Description

Technical Field

[0001] This utility model relates to the technical field of sliding door and window locks, and in particular to a universal self-collision lock. Background Technology

[0002] Self-closing locks are a common lock structure for sliding windows and are very convenient to use. When locked, the insert is pushed to the frame along with the window sash, and the insert of the window sash automatically pushes open the latch plate inside the lock and enters the lock. The latch plate then automatically resets to achieve locking. When unlocking, the latch plate is lifted to open the latch plate and the window sash can be pushed or pulled. The main structure of current self-closing locks includes a latch plate and two locking plates that abut against each other. One locking plate is pushed by a lever at one end of the handle, and the locking plate drives the other locking plate, thereby making the two locking plates move away from each other and allowing the insert plate to detach from the two locking plates. However, current self-closing locks can only be moved in one direction to make the locking plates move outward by using the protrusion on the latch plate. Therefore, existing self-closing locks need to be installed according to the direction of push and pull, which is not conducive to production and installation, and also increases inventory pressure.

[0018] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As shown in the attached figure, this utility model discloses a universal self-collision lock, comprising a lock body 1, a buckle plate 2, and a locking structure 3. The locking structure 3 includes two symmetrically arranged locking plates 30 inside the lock body 1, which are rotatably connected to the lock body 1. The buckle plate 2 has a rotating part 20 rotatably connected to the lock body 1 in the middle. The rotating part 20 includes a rotating shaft rotatably connected to the lock body 1. The rear side of the rotating part 20 has a protruding ridge 22 for driving the push plate 4 to slide up and down. The two locking plates 30 are not in direct contact. The ridge 22 is connected to the push plate 4, and the push plate 4 drives the two locking plates 30 to unfold relative to each other. The push plate 4 is an integrally formed sheet structure.

[0020] The lock body 1 has two rotatable locking plates 30 inside. Specifically, the lock body 1 has two pins 101, and each locking plate 30 has a through hole. The two pins 101 are respectively inserted into the corresponding through holes, so that the locking plates 30 are rotatably connected to the lock body 1. The push plate 4 has an opening 40 corresponding to the protruding ridge 22. The protruding ridge 22 passes through the opening 40. The push plate 4 slides up and down by rotating the buckle plate 2. That is, by bending the buckle plate 2, the protruding ridge 22 on the rear side swings up or down, so that the push plate 4 slides up or down. Preferably, the two pins 101 and the opening 40 are both set on the same vertical line, and the opening 40 is located in the middle of the two pins 101. The push plate 4 is provided with an abutment plate 401 and abutment plates 402. The abutment plate 401 is located on the left side of the pin 101 and abuts between the two locking plates 30. The bbutment plates 402 are located on the right side of the pin 101 and abut against the two locking plates 30 on opposite sides. There are two locking plates 30, and correspondingly, there are two bbutment plates 402. The two bbutment plates 402 abut against the two locking plates 30 on opposite sides. That is, the abutment plate 401 and the two bbutment plates 402 are located on the left and right sides of the rotation point of the locking plate 30, respectively.

[0021] This utility model discloses a universal self-locking principle and effect. The latch plate 2 is connected to the lock body 1 via a rotating part 20 located in the middle. A push plate 4 is connected via a protruding rib 22 on the rotating part 20. The push plate 4 drives the two locking plates 30 to unfold relative to each other. The user can unlock the lock by prying either side of the latch plate 2. (See reference.) Figure 3-5If the user pulls the buckle plate 2 upwards, the protrusion 22 swings downwards and drives the push plate 4 to slide down. The upper b-contact plate 402 then pushes the upper locking piece 30 downwards, while the a-contact plate 401 pushes the lower locking piece 30, thus allowing the two locking pieces 30 to move away from each other and unfold outwards. Conversely, if the user pulls the buckle plate 2 downwards, the protrusion 22 swings upwards and drives the push plate 4 to slide upwards. The lower b-contact plate 402 then pushes the lower locking piece 30 upwards, while the a-contact plate 401 pushes the upper locking piece 30. This eliminates the need to distinguish between left and right installation, improving installation efficiency. At the same time, since the two locking pieces 30 have the same structure, they do not need to be produced separately, reducing production and inventory pressure.

[0022] Specifically, a tension spring 31 is connected between the two locking plates 30, and the tension spring 31 mainly serves to help the two locking plates 30 reset.

[0023] Specifically, the lock body 1 has a groove 102 on the front side, and the buckle plate 2 is set in the middle of the groove 102. Setting the buckle plate 2 in the middle of the groove 102 makes the lock body 1 look more coordinated and makes it easier for the user to pry the buckle plate 2 from the top or bottom. The groove 102 has reserved space on both sides to facilitate the user to pry the buckle plate 2.

[0024] Based on this, a locking key 50 is rotatably disposed within the groove 102, and the push plate 4 has a square hole 405. One end of the locking key 50 has a flat plate portion 500 extending into the square hole 405. The length of the flat plate portion 500 corresponds to the height of the square hole 405, and both ends of the flat plate portion 500 in the length direction can abut against the upper and lower sides of the square hole 405. This is a child-locking structure to prevent children from accidentally touching it. Specifically, the front of the locking key 50 has a structure for the user to turn, and it can be directly set as a hexagonal hole for the user to pass through. When the key is turned, the deadbolt 50 is integrally formed and can rotate on the lock body 1. The width of the flat plate 500 is less than the height of the square hole 405. Under normal conditions, the flat plate 500 is located inside the square hole 405. However, since the width of the flat plate 500 is less than the height of the square hole 405, it does not affect the sliding of the push plate 4. When the deadbolt 50 is rotated 90 degrees, the flat plate 500 is placed vertically. At this time, the two ends of the flat plate 500 in the length direction abut against the corresponding sides of the square hole 405, so that the push plate 4 cannot slide up and down, thereby achieving the deadbolt effect.

[0025] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
