Description

Multifunctional door lock auxiliary tool

technical field

The invention relates to the field of auxiliary tools for locks, in particular to a multifunctional door lock auxiliary tool.

Background technique

In the process of installing and maintaining the door lock, sometimes the cooperation between the oblique tongue of the door lock and the guide plate of the door frame is too tight, resulting in the problem of poor movement of the tongue. The general adjustment method for such problems is to adjust the door frame guide after removing it, which is time-consuming and labor-intensive.

SUMMARY OF THE INVENTION

In order to solve the above problems, the present invention provides a multifunctional door lock auxiliary tool that can adjust the gap between the oblique tongue and the door frame guide piece without disassembling the door frame guide piece, and is easy to grasp, easy to use, and easy to carry.

In order to achieve the above purpose, the multifunctional door lock auxiliary tool designed by the present invention is a crowbar. On the side of the crowbar, the wedge opening faces the axial end face of the crowbar. The function of the wedge opening is to insert the end of the crowbar with the wedge opening into the oblique tongue hole of the guide plate of the door frame when installing the door lock, and then align the wedge opening with the edge of the inward roll on the guide plate of the door frame. Then use the door frame as a fulcrum, pry the crowbar, and then adjust the matching gap between the inward curling edge and the door lock tongue through the wedge opening, so that the door lock tongue can smoothly slide back and forth on the door frame guide plate, thereby The door can be opened and closed smoothly.

In order to fit the square steel hole of the door lock and test the quality of the lock body, the crowbar has a solid square section, and its axial section size is 8×8mm. The square steel in the household door lock is used as a standard part, and its section size is 8×8mm. When installing or replacing the door lock, you can insert the crowbar into the square steel hole corresponding to the square steel on the fixed lock body, and then hold it. Hold and turn the crowbar to test the quality of the lock body.

In order to facilitate grasping and apply rotational force, the crowbar is L-shaped, including a long side and a short side. The L-shaped crowbar is easy to grasp during use, and is conducive to turning and applying force. At the same time, both the long side and the short side can be used as working parts to meet various needs.

In order to facilitate the length measurement at zero time, a scale mark is provided on the side of the crowbar. In actual production and life, the crowbar can also be used as a scale to measure the length of an object.

In order to further provide the depth measurement function of the square steel hole of the door lock, the zero scale of the scale mark corresponds to the axial end face of the long side portion. When installing and replacing the door lock, the long side of the crowbar can be inserted into the square steel hole corresponding to the square steel on the fixed lock body, and the length of the required square steel can be measured.

In order to prolong the service life of the scale mark, the scale line on the scale mark is a concave ring line surrounding the outer surface of the shaft of the crowbar. The concave ring line surrounding the crowbar is conducive to the observation of the scale during measurement, and reduces the negative impact of bumps and scratches on the scale during use.

In order to further increase the convenience of measuring the square steel hole, and at the same time consider the cost of product production, the scale value of the scale mark is in units of 2cm, and the corresponding scale value mark is set between the concave ring lines. When measuring the square steel required for the lock body, since the standard size increase of the square steel is 5mm, the scale unit of 2cm can completely estimate the value exceeding the scale line by the naked eye, so as to calculate the total required square steel. At the same time, the spacing of 2cm corresponds to the crowbar with a width of 8mm, so that the marked scale value is appropriate and easy to observe. It will not affect the observation of the scale value because the scale value is too narrow, resulting in difficult observation.

A further solution is that the total length of the scale marks is 10cm. The size of the square steel sold in the market is basically within 140mm, and the size of the square steel of the household lock that often needs to be replaced in actual production and life is basically within 100mm, so the scale of 10cm is enough for the actual needs of household lock replacement, while more than 10cm The square steel can be roughly estimated according to its length exceeding 10cm, and the estimated range can be narrowed; limiting the length of the scale value can limit the total size of the crowbar as small as possible, making the crowbar light and easy to carry, and does not take up too much space when carrying .

In order to ensure the matching effect between the wedge opening and the guide piece of the door frame, the included angle between the wedge opening and the side surface is between 30° and 60°. The angle between the wedge opening and the crowbar is limited by the size of the corresponding oblique tongue opening on the guide plate of the door frame, and cannot be too large or too small.

In order to ensure the service life of the crowbar and the wedge opening, the end of the crowbar where the wedge opening is located is quenched and tempered. Increases the stiffness of the crowbar end to avoid breakage when using the wedge.

The multifunctional door lock auxiliary tool designed by the present invention is a crowbar with a wedge opening at one end. The edge of the hole is curled inward, and the installation gap between the curled edge and the oblique tongue can be adjusted by prying the curled edge. Secondly, the crowbar is also a solid square steel with a cross-section of 8×8mm, which makes the crowbar suitable for home use. During the installation and replacement of the lock, it can be inserted into the hole where the square steel of the lock body is located to perform a rotation test on the lock body. Thirdly, the shape of the crowbar is L-shaped, including the long side and the short side, which is easy to grasp or apply force, and The structure is simple and easy to carry. In addition, the long side of the crowbar is provided with a scale mark with the zero scale line aligned with the end face and a corresponding scale mark, so that the crowbar can be inserted into the square steel hole to adjust the required square steel length. The measurement is carried out, and the concave ring line surrounding the surface of the crowbar corresponding to the scale line on it is conducive to the observation during measurement, and its scale value can be observed from any angle.
