[0002] The rolling door lock tongue is an important component of the rolling door lock. Its design and quality are directly related to the safety performance of the rolling door. The lock tongue is usually located at the bottom of the lock body and is used to connect to the ground or other fixed objects to ensure that the rolling door can be firmly locked when closed.
[0003] Existing rolling door locks push the connecting rod to both sides through the lock tongue, but after long-term use of the rolling door, the lock tongue part may be deformed due to wear, resulting in failure to cooperate properly, resulting in deviation, and then causing the lock tongue to fail to extend and retract smoothly during later use. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a rolling door guide rail lock tongue which is easy to install.
[0005] The utility model is implemented by the following technical scheme: a rolling shutter door guide rail lock tongue that is easy to install, comprising a lock front cover, a lock rear cover is arranged at the front end of the lock front cover, a threaded rod is threadedly connected to the inner wall of the lock rear cover, a lock core is rotatably connected to the inner wall of the lock front cover, lock tongues are arranged at both ends of the lock front cover, a sliding block is fixedly connected to the upper end of the lock tongue, a sliding rail is slidably connected to the surface of the sliding block, a driving gear is fixedly connected to the surface of the lock core, a rack is fixedly connected to the left end of the lock tongue, a T-shaped slider is fixedly connected to the bottom of the rack, and the guide rail is fixedly connected to the inner wall of the lock front cover.
[0006] Through the above technical solution, the sliding block slides on the inner wall of the slide rail to limit the position of the lock tongue, thereby avoiding the deviation of the lock tongue position during long-term use, ensuring the stability and accuracy of the lock tongue during movement, and enhancing the overall performance of the lock.
[0007] As a further improvement of the above solution, the lock front cover and the lock rear cover are threadedly connected by a threaded rod, and both ends of the lock core pass through the lock front cover and the lock rear cover.
[0008] Through the above technical solution, the lock back cover can be disassembled by disassembling the threaded rod.
[0009] As a further improvement of the above solution, the driving gear is located inside the front cover of the lock, and the driving gear is meshed with the rack.
[0010] Through the above technical solution, the lock core is rotated to drive the driving gear to rotate, thereby driving the gears to move away from each other, and then pushing the lock tongue to move, so that the lock tongue pushes the connecting rod connected to the outside to move.
[0011] As a further improvement of the above solution, the rack is located inside the lock front cover, and the surface of the T-shaped slider is slidably connected to the inner wall of the guide rail.
[0012] Through the above technical solution, the position of the rack is limited by the sliding connection between the T-shaped slider and the inner wall of the guide rail, thereby improving the stability during movement, ensuring that the lock tongue can be smoothly extended and retracted, and extending the service life of the lock tongue.
[0013] As a further improvement of the above solution, openings are provided at both ends of the lock front cover, inner walls of the openings are fixedly connected to the top of the slide rail, and limiting plates are provided at both ends of the lock rear cover.
[0014] Through the above technical solution, the position of the rack after movement is limited by the limiting plate.
[0015] As a further improvement of the above solution, the inner wall of the lock rear cover is threadedly connected with a bolt, and the bolt passes through the lock rear cover and is threadedly connected to the inner wall of the limiting plate.
[0016] Through the above technical solution, the limit plate can be removed by dismantling the bolts, and then the lock tongue is pulled to drive the rack to slide on the inner wall of the guide rail to remove the lock tongue, which is convenient for subsequent replacement of the lock tongue, facilitates subsequent maintenance, and improves practicality.
[0017] As a further improvement of the above solution, the surface of the limiting plate contacts the inner wall of the opening, and the limiting plate is located at the lower end of the locking tongue.
[0018] Through the above technical solution, the lock tongue and the rack can be removed through the opening position, which is convenient for subsequent replacement of the lock tongue and improves the convenience of subsequent maintenance.
[0019] Compared with the prior art, the beneficial effects of the present invention are:
[0020] The utility model provides a sliding block, a slide rail rack, a guide rail and a T-shaped slider, and specifically, rotates the lock core to rotate the driving gear, thereby driving the rack meshing with the driving gear to move, so that the rack moves to both sides, thereby pushing the lock tongue to move to both sides, and at the same time the sliding block slides on the inner wall of the slide rail to limit the moving position of the lock tongue, thereby ensuring the stability of the lock tongue when moving, avoiding the phenomenon that the lock tongue is prone to deviation due to long-term use, and improving the service life of the lock tongue. The guide rail is used to limit the T-shaped slider, so that the rack is more stable when moving, thereby ensuring the stability and accuracy of the lock tongue when moving.
[0021] The utility model provides a limit plate and a bolt. Specifically, when the lock tongue needs to be disassembled and replaced, the threaded rod is first disassembled, and then the bolt is disassembled, the lock back cover is removed, and then the limit plate is removed, so that the rack is not limited by the limit plate, and then the lock tongue is pulled to drive the rack to move and be removed from the opening, and the lock tongue can be replaced, which is convenient for subsequent replacement of the lock tongue and improves convenience during use.
