Description

A New Positionable Door Stop Hydraulic Door Closer

technical field

The utility model relates to a hydraulic door closer, in particular to a novel hydraulic door closer capable of positioning and stopping the door.

Background technique

Door closers are mainly used in commercial and public buildings, but can also be used in homes. At present, the most common door closers in life are spring door closers and hydraulic door closers. Spring door closers can realize the function of automatic door closing, but the moment of automatic door closing will cause a large impact on the door frame, which will Resulting in a reduction in the life of the door and frame. The hydraulic door closer can solve this problem very well. The hydraulic door closer can not only make the door close automatically, but also protect the door frame and the door body.

The working principle of the hydraulic door closer: when the door is opened, the door body drives the connecting rod to move, so that the transmission gear rotates, and the rack plunger is driven to move in one direction. During the movement of the plunger, the spring is compressed to store energy. When people let go of the hand, the energy absorbed by the spring due to compression is released. Under the push of the spring force, the rack plunger moves in the opposite direction to make the door return and realize the function of automatic door closing. Although the size and size of different hydraulic door closers are different, the principle of hydraulic door closers is basically the same.

The purpose of the hydraulic door closer is to make the door close by itself to limit the spread of fire and ventilation in the building. However, it has certain functional limitations, that is, it will automatically close after opening within a certain angle, which cannot meet the requirement of temporarily positioning the door. Most of the existing hydraulic door closers do not have the function of positioning and stopping the door, and the positioning door closer basically stops the door at 90 degrees and the principle is relatively complicated.

Contents of the invention

In view of the above problems, the problem to be solved by this utility model is to break through the limitation that the original hydraulic door closer cannot be positioned at any position to stop the door, and to provide a door that can be positioned at any angle to stop the door, and can complete positioning and non-positioning, A new type of hydraulic door closer that can easily switch between the door-stop mode and the non-door mode.

The utility model is a novel positionable door stop hydraulic door closer, comprising a fixed connection seat (1), a connecting rod (2), a nut (3), a connecting rod (4), a positionable door stop structure (17), Connecting rod (11), hydraulic chamber (12), the connecting rod (4) is threadedly connected with the connecting sleeve (5); the connecting rod (11) is loosely fitted on the pull rod (7); The positionable door stop structure (17) includes a connecting sleeve (5), a rotating shaft (6), a pull rod (7), a steel ball (8), a groove (9), a pull rod spring (10), a screw (13), Upper stop device (14), lower stop device (15), steel ball spring (16). The connecting sleeve (5) is set on the screw (13) with loose fit; the upper end of the tie rod spring (10) is fixed in the lower stopper (15), the lower end is free, and the loose fit is set on the tie rod (7) Above; the lower stop (15) has a groove (9); the upper stop (14) has a built-in steel ball spring (16) and steel ball (8); the steel ball spring (16) The upper end is fixed to the upper stopper (14), and the lower end is in fixed contact with the steel ball (8); the pull rod (7) is rigidly connected to the lower stopper (15); the lower stopper (15) is over Ying fit is sleeved in the rotating shaft (6).

A new type of hydraulic door closer that can be positioned to stop. The functions include: when the pull rod is pulled down, the upper and lower stops are separated, and the door has the function of an ordinary hydraulic door closer; when the pull rod is pushed up, the upper and lower stops are separated. The two stoppers are tightly fitted together. As the door rotates to a certain angle, the steel ball can just be stuck in the groove to realize the function of positioning and stopping the door; and the position of the groove can follow the rotation of the lower stopper. It can be adjusted so that the stuck position will be different, so as to realize the function of positioning the door at any angle.

detailed description

In order to describe the implementation process of the utility model in more detail, the utility model will be described below in conjunction with the accompanying drawings.

As shown in the front view of the utility model in Figure 1 and the side view of the utility model in Figure 2, the utility model has the function of a common hydraulic door closer when the pull rod is pulled down under normal conditions. That is, when the door is opened, the door body drives the connecting rod to move, so that the transmission gear rotates, and the rack plunger is driven to move in one direction. During the movement of the plunger, the spring is compressed to store energy. When the person releases the handle, the spring is The energy absorbed by the compression is released, and under the push of the spring force, the rack plunger moves in the opposite direction to return the door and realize the function of automatic door closing.

The utility model preferably uses a positionable door stop structure, as shown in Figure 3, the schematic diagram of the pull rod of the utility model, the partial sectional view of the utility model in Figure 4, and the schematic diagram of the spring steel ball of the utility model in Figure 5, the door stop device can realize the door stop at any position . The structure of the positionable door stop is: there is a groove in the lower stop, and a steel ball spring and a steel ball are built in the upper stop. The steel ball is connected to the steel ball spring, and the steel ball spring gives the steel ball force to pop out. The spring is in a compressed state. With the rotation of the door driving the rotation of the door stopper, the groove is also rotating. When it turns to the position of the steel ball, the steel ball will bounce off under the action of the spring force and be stuck in the groove to realize the stop. door function.

As shown in Figure 3, the pull rod schematic diagram of the utility model, the lower stopper and the pull rod are rigidly connected, and the pull rod can be pulled down or pushed up to drive the lower stopper to separate or approach the upper stopper. The lower stopper is set in the rotating shaft, and it rotates around the rotating shaft as a whole. Through the rotation, the lower stopper and the pull rod will rotate to a certain angle. At this time, the position of the groove will change with the lower stopper. The angle of the door also changes accordingly, so that the function of stopping the door at any position can be realized.

The benefits of the utility model are: compared with the existing hydraulic door closers, in addition to the basic function of automatically closing after opening, it can also realize the function of stopping and positioning the door at any position, that is, in addition to being used to limit the spread of fire and Excellent ventilation, through the positionable door stop structure, it is also easy to adjust the position of the door stop position, and realize the function of flexible switching between positioning and non-positioning, door stop and non-stop door.
