Abstract
Description
Technical Field
[0001] The present invention belongs to the field of lock bodies and relates to a door lock buckle plate that facilitates the left - right adjustment of the position of the lock tongue hole. Technical Background
[0002] A door lock includes two parts. The lock body part is installed on the door, and the buckle box part is installed on the door frame. When the lock tongue in the lock body on the door extends into the buckle box on the door frame, the door is locked. The buckle box part includes a buckle box installed in the lock tongue groove of the door frame and a buckle plate installed outside the buckle box. In order to ensure that the door does not shake after being locked, the width of the lock tongue and the width of the lock tongue hole on the buckle plate are as close as possible. However, this will greatly improve the accuracy requirements for installation, making the installation difficulty increase. If the installation is wrong, since the fixing screw holes have been drilled, if you want to adjust the position again, the effect will also become worse, and the fixing of the buckle plate will not be so firm. Summary of the Invention
[0003] According to the above problems, the present invention provides a door lock buckle plate that facilitates the left - right adjustment of the position of the lock tongue hole. The device has the advantages of simple structure, convenient adjustment of the position of the lock tongue hole, and thus convenient installation of the buckle plate.
[0004] The object of the present invention is achieved as follows:
[0005] A door lock buckle plate that facilitates the left - right adjustment of the position of the lock tongue hole, including a buckle plate body. A first lock tongue hole is formed on the buckle plate body. An adjusting plate is provided on the buckle plate body. A second lock tongue hole corresponding to the first lock tongue hole is formed on the adjusting plate. Longitudinal positioning blocks are formed on the upper and lower sides of the back of the second lock tongue hole. The longitudinal positioning blocks are arranged in the first lock tongue hole and abut against the upper and lower inner walls of the first lock tongue hole. Adjusting holes are formed at the upper and lower ends of the adjusting plate. Eccentric screws are provided in the adjusting holes. The rotating shaft of the eccentric screw is rotatably connected to the buckle plate body and axially fixed.
[0006] Through the setting of the longitudinal positioning blocks, the longitudinal positioning blocks are arranged in the first lock tongue hole and abut against the upper and lower inner walls of the first lock tongue hole, thereby defining the longitudinal relationship between the adjusting plate and the buckle plate body and preventing longitudinal movement. Then, through the setting of the eccentric screws, by rotating the eccentric screws, the left - right adjustment of the adjusting plate is realized, and thus the left - right adjustment of the position of the second lock tongue hole is realized. The width of the second lock tongue hole is adapted to the width of the lock tongue. The width of the first lock tongue hole is greater than that of the second lock tongue hole. In this way, even if the position of the buckle plate is inaccurate during installation, it can be adjusted left - right through the eccentric screws.
[0007] The present utility model is further provided as: The adjusting plate includes a bottom plate and a soft rubber coating. The soft rubber coating is injection - molded at the second lock tongue hole and wraps the lock tongue hole.
[0008] Through the setting of soft rubber coating, firstly, it can play a role of silencing, and secondly, it can play a role of protecting the lock tongue.
[0009] The utility model is further configured as follows: the longitudinal positioning block is injection molded together with the soft rubber coating.
[0010] The utility model is further configured as follows: the eccentric screw comprises a handle portion, an eccentric adjustment portion and a rotating shaft in sequence from top to bottom, and the eccentric adjustment portion is arranged corresponding to the inner wall of the adjustment hole.
[0011] Through the above settings, the screw can be a hexagonal screw, a flat screw or a cross screw. The eccentric screw is rotated by a screwdriver or a hexagonal wrench. Since the axial direction of the rotating shaft is fixed, after rotation, the eccentric adjustment part is offset left and right, thereby driving the adjustment plate to move left and right, thereby driving the second lock tongue hole to adjust left and right.
[0012] The utility model is further configured as follows: the adjusting hole is provided with a longitudinal giving way portion.
[0013] By setting the longitudinal relief portion, when the eccentric screw rotates, the longitudinal offset of the eccentric adjustment portion caused by the rotation will not cause the adjustment plate to move longitudinally, so the adjustment hole can be elliptical or rectangular.
[0014] The utility model is further configured as follows: a positioning mark is also provided on the front end surface of the eccentric screw.
[0015] Through the design of the positioning mark, the user can more clearly understand the rotation angle of the eccentric screw.
[0016] The utility model is further configured as follows: a first square tongue hole is formed below the buckle plate body, a square tongue buckle plate is provided below the adjustment plate, a second square tongue hole is formed on the square tongue buckle plate, and the second square tongue hole is arranged corresponding to the first square tongue hole.
[0017] By setting the square tongue buckle plate, the lock body with a square tongue can be applied.
[0018] The utility model is further configured as follows: the upper end of the square tongue buckle plate is formed with a transverse shift groove for the adjustment plate to move left and right, the front end surface of the transverse shift groove is the adjustment plate fixing surface, and the lower end surface of the transverse shift groove is the transverse shift guide surface.
[0019] By setting the transverse movement groove, the adjustment plate can be fixed and the transverse movement of the adjustment plate can be guided and stabilized at the same time.
[0020] The utility model is further configured as follows: a buckle is formed on the back side of the square tongue buckle plate.
[0021] The utility model is further configured as follows: a screw fixing hole is formed on the square tongue buckle plate.
[0022] The prominent and beneficial technical effects of the present invention compared with the prior art are as follows: Through the provision of the longitudinal positioning block, the longitudinal positioning block is arranged in the first lock tongue hole and abuts against the upper and lower inner walls of the first lock tongue hole, thereby defining the longitudinal relationship between the adjusting plate and the buckle body and preventing longitudinal movement. Then, through the provision of the eccentric screw, by rotating the eccentric screw, the left and right adjustment of the adjusting plate is achieved, thereby realizing the left and right adjustment of the position of the second lock tongue hole. The width of the second lock tongue hole is adapted to the width of the lock tongue, and the width of the first lock tongue hole is greater than that of the second lock tongue hole. In this way, even if the position of the buckle is inaccurate during installation, it can be adjusted left and right through the eccentric screw. BRIEF DESCRIPTION OF THE DRAWINGS
