Abstract
Description
Technical Field
[0001] This utility model mainly relates to the field of lock technology, specifically to an anti-lock lock. Background Technology
[0002] Common lock bodies on the market include single-prong lock bodies, three-prong lock bodies, etc. They generally use gear transmission to drive the internal bolt of the lock body to extend and retract. Because the gears and push rod inside the lock body are prone to jamming, the bolt cannot extend and retract normally. In other words, the internal locking problem is prone to occur when the lock body is in operation, which makes the lock body prone to motion interference and damage, affecting the reliability of the lock body.

One end of the fork overlaps with the surface of the second slider to drive the second slider to move.
[0012] This utility model provides an anti-lock device that uses a connecting rod to drive the bolt to extend and retract, avoiding the problem of gears jamming during rotation, thereby achieving the anti-lock effect and improving the reliability of the lock body. Attached Figure Description
[0013] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0014] Figure 1 This is a schematic diagram of the internal structure of the anti-lock device in this utility model;
[0015] Figure 2 This is a schematic diagram of the internal structure of an anti-lock device of another size in this utility model. Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] Figure 1 The diagram shows the internal structure of the anti-lock device of this utility model. The anti-lock device includes a lock body shell 1, a square tongue assembly 2, and a lock tongue assembly 3. The lock body shell 1 is provided with a keyhole 11. The square tongue assembly 2 and the lock tongue assembly 3 are installed and fixed below the keyhole 11. The key rotates through the keyhole 11 and contacts the square tongue assembly 2, thereby pushing the square tongue 21 out of the lock body shell 1.
[0018] Specifically, the third slider 22 is provided with a first sliding groove, and the first sliding pin 23 is disposed in the first sliding groove 221 and can move along the first sliding groove. When the key is turned, it contacts the third slider 22, pushing the third slider 22 down. The first sliding pin 23 moves up along the first sliding groove 221, so that the third slider 22 is in complete contact with the square tongue 21, allowing the square tongue 21 to extend and retract smoothly, thus improving the anti-theft performance.
[0019] Specifically, a push plate 31 is provided between the latch assembly 3 and the square latch assembly 2. The latch assembly 3 includes a fork 32. The push plate 31 controls the linkage movement of the latch assembly 3 and the square latch assembly 2. When the user locks the square latch assembly 2 with a key, the push plate 31 is engaged between the square latch assembly 2 and the latch assembly 3, thereby locking the latch assembly 3. One end of the push plate 31 is installed below the keyhole 11, and the other end is provided with a rotating shaft. The push plate 31 is movably connected to the fork 32 through the rotating shaft 311. The fork 32 is provided with a square hole 321, which is used to connect to the door lock handle. When the user turns the handle, it can drive the fork 32 to rotate, thereby driving the latch assembly 3 to perform locking and unlocking operations.
[0020] Furthermore, the latch assembly 3 also includes a second sliding pin 34, a first slider 33, a second slider 35, a slide rod 36, and a latch 37. The fork 32 is provided with a second sliding groove, the second sliding pin 34 is disposed in the second sliding pin 34 and can move along the second sliding groove 322, the fork 32 is also provided with a drive groove, the first slider 33 is disposed in the drive groove 323 and abuts against the fork 32, one end of the fork 32 overlaps with the surface of the second slider 35, and the latch 37 and the second slider 35 are connected by the slide rod 36. By rotating the handle, when the fork 32 is rotated clockwise, the first slider 33 is driven to slide downward, so that the second sliding pin 34 moves upward along the second sliding groove 322, thereby pushing the second slider 35 to move inward, causing the latch to retract into the lock body shell 1, achieving the function of quick unlocking.
[0021] Specifically, Figure 2 A schematic diagram of the internal structure of an anti-lock device of another size according to this invention is shown. Please refer to it. Figure 2 In another feasible embodiment, the lock body can be configured as a narrow structure, so that the various components inside the lock body are arranged compactly, thereby adapting to the thermally broken aluminum door body.
[0022] This utility model provides an anti-lock device that uses a connecting rod to drive the bolt to extend and retract, avoiding the problem of gears jamming during rotation, thereby achieving the anti-lock effect and improving the reliability of the lock body.
[0023] Furthermore, the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model.
