Description

a hinge

technical field

The invention relates to a hinge, in particular to a hinge which is convenient for punching.

Background technique

A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow rotation between them. Hinges may be constructed from moving components, or from materials that fold. In the prior art, the two foldable parts of the hinge are mostly integrally formed. In this way, when a hole needs to be punched in the folded part, it must be penetrated from one end of the folded part to the other, which usually increases the difficulty in processing. At the same time, Because the depth of punching is deep, the precision between each hole is also reduced, making it difficult to install the connecting shaft, or the rotation is not flexible enough after installation.

Contents of the invention

In order to solve the above-mentioned technical problems such as difficult installation and inflexible rotation caused by low precision, the invention discloses a new type of hinge, which is composed of a connecting block and two bases, and the two bases are connected through the connecting block. At the same time, the two bases can rotate around the connecting block. The bases are composed of a receiving groove and mounting seats located at both ends of the receiving groove. The receiving groove and the mounting seats are connected by a detachable connecting piece.

On the basis of the above technical solution, in order to further optimize the technical effect, a further technical solution is that a protrusion is provided in the accommodating groove, and a shaft hole for connecting with the connecting block is provided in the protrusion, and the protrusion The shape is adapted to the shape of the connecting block.

Further, a shaft for pivotally connecting the base and the connection block is provided in the shaft hole of the protrusion, and the shaft runs through the entire receiving groove, and the two end surfaces of the shaft are respectively in contact with the mounting seats at both ends.

Further, bosses for positioning are provided on the outer walls of both ends of the receiving groove, and grooves are provided on one side of the mounting seat, and the grooves are adapted to and contact with the shape of the bosses.

Further, the top surface of the boss and the bottom surface of the groove are respectively provided with a positioning pin hole, and the two positioning pin holes are connected by a pin.

Further, the mounting base is also provided with adjustment screws.

Further, the connecting block is composed of connecting pieces, the number of connecting pieces is not less than two, and the connecting pieces are pivotally connected by connecting shafts.

Further, the middle part of the entire base is concave, and the upper surfaces of the mounting seats at both ends are flush with the upper edge of the receiving groove.

In the present invention, the base is divided into three sections, that is, the accommodation groove and the connecting seats at both ends. This design makes it only necessary to penetrate the accommodation groove during the production, processing and drilling process. As a result, the depth of punching becomes shallower, and the length of the connecting shaft is also shortened. It makes the processing easier and the accuracy of the hole is easier to guarantee.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

A novel hinge disclosed by the invention consists of a connecting block and two bases, the two bases are connected through the connecting block, and the two bases can rotate around the connecting block. These several technical features should be the common technical features of the existing hinges, and also the necessary technical features to form the folding hinge. On this basis, the base of the hinge in the present invention is composed of a receiving groove and mounting seats located at both ends of the receiving groove, and the receiving groove and the mounting seat are connected by a detachable connecting piece. That is to say, the base of the hinge used for folding in this solution is not integral, but consists of three parts, a receiving groove and two mounting seats. At the same time, the mounting base can be disassembled from the receiving groove. This design makes it only necessary to penetrate from one end of the receiving groove to the other end of the receiving groove when processing the shaft hole for connecting the base and the connecting block. The shaft for connection only needs to go through the receiving groove, and finally install the mounting seats at both ends. In this solution, both the shaft and the hole used for connection are shortened, thereby improving the processing accuracy and convenience of the hole, and finally obtaining a higher quality hinge.

On the basis of the above technical solution, the preferred solution is that a protrusion is provided in the accommodating groove, and a shaft hole for connecting with the connecting block is provided in the protrusion, and the shape of the protrusion is consistent with that of the connecting block. The shape matches. Because the hinge involves rotation, it will have the design of the shaft hole. Some of them bend a metal sheet to process the shaft hole, but the strength of the shaft hole is generally low and easy to deform. In this solution, protrusions are directly set in the receiving groove, and then holes are drilled on the protrusions. Although the materials and processing are much more complicated, such hinges generally have high strength and can be rotated repeatedly for a long time without deformation. In addition, some other structures of the hinge can also be accommodated therein. When the hinge is installed on the door and window, the accommodating groove can be integrally embedded in the corresponding recessed part of the door and window. Then it is fixed by the mounting bases at both ends, which can realize the hidden installation of the hinge.

Preferably, a shaft for pivotally connecting the base and the connection block is provided in the shaft hole of the protrusion, and the shaft runs through the entire receiving groove, and the two end surfaces of the shaft are respectively in contact with the mounting seats at both ends. Generally, there is a pivot structure in the hinge, and then the shaft and the shaft hole become the basic necessary features. The unique three-stage design of the base in this solution makes the shaft and the shaft hole shorter. In this solution, the shaft hole penetrates from one end of the base body to the other end, and at the same time, both ends of the shaft are in contact with the mounting seat. Because the mounting base is fixedly connected to both ends of the base body, the mounting bases at both ends can sandwich the connecting shaft, thereby restricting the axial movement of the shaft and making the entire hinge connection more stable.

Preferably, bosses for positioning are provided on the outer walls of both ends of the receiving groove, and grooves are provided on one side of the mounting seat, and the grooves are adapted in shape and contact with the bosses. Although the mounting base and the base are fixedly connected through the connecting piece, there will be some deviation in position when the connecting piece is connected, so the design of the positioning boss and the corresponding groove is to avoid this deviation. When the positioning boss is in contact with the groove, the mounting base can be temporarily positioned on the receiving groove, and then the base and the mounting base are fixedly connected by the connecting piece. Due to the limitation of the positioning bosses and grooves, it is not suitable for relative sliding between the mounting seat and the base during the installation process, and at the same time, the overall hinge after installation can be made more stable.

Preferably, the top surface of the boss and the bottom surface of the groove are respectively provided with a positioning pin hole, and the two positioning pin holes are connected by a pin. The design of pin hole here and the design of above-mentioned boss and groove, its purpose is roughly the same. The design of the boss matching the groove can limit the relative position of the mounting seat and the base, and the design of the pin hole and the pin is also to limit the relative position between the mounting seat and the base, that is, to limit the relative radial displacement of the two, and The joint design of the two can make the restriction effect more significant.

Preferably, an adjustment screw is also provided on the mounting base. The setting of the adjusting screw can finely adjust the relative position between the base and the connecting block, and then adjust the positional fit between the shaft and the shaft hole, reduce the friction between the shaft and the shaft hole, and finally make the rotation of the entire hinge more flexible.

Preferably, the connecting block is composed of connecting pieces, the number of connecting pieces is not less than two, and the connecting pieces are pivotally connected by connecting shafts. The design of multiple connecting pieces in the connecting block can not only enhance the mechanical strength of the connecting block, but also make the structure of the connecting block more flexible, and the hinge can rotate at a larger angle.

Preferably, the middle part of the entire base is concave, and the upper surfaces of the mounting seats at both ends are flush with the upper edge of the accommodating groove. With this design, when the hinge is installed on the door and window, the concave part can be completely fitted into the recess of the door and window. At the same time, the mounting seat is flush with the upper edge of the receiving groove, so that only the mounting seat is exposed outside, which truly realizes the hidden design.

The hinge disclosed by the present invention can significantly improve the ease of machining the shaft hole due to the three-stage design of the base, and also improve the machining accuracy. With the design of the accommodating groove, the concealed hinge installation is realized. Combined with the design of the limit boss, groove, limit pin and adjustment screw, the position of the base can be fixed more precisely, and at the same time, fine adjustment can be made to make the friction between the base and the connecting block smaller when rotating. It is more flexible and stable for a long time without deformation.

Here, up, down, left, right, front, and back only represent their relative positions and not their absolute positions. The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technologies fields, all of which are equally included in the scope of patent protection of the present invention.
