Description

Technical Field

[0001] This utility model relates to the technical field of touch locks, and in particular to a universal double-point touch lock. Background Technology

[0002] Sliding windows are a common type of window, widely used due to their advantages such as not taking up interior space, flexible opening, and low price. The latch lock, a common lock mechanism for sliding windows, is very convenient to use. When locked, the latch is pushed to the frame along with the window sash, and the latch automatically pushes open the latch plate inside the lock, which then automatically resets to lock. To open, simply lift the latch plate to release the latch plate and slide the window sash. (Refer to Publication No.: CN219471799U, Patent Title: "A Double-Point Lever Lock for Sliding Windows") According to the utility model patent for "pump lock", our company designed a double-point bump lock to solve the problem of insufficient locking strength and improve the stability of locking. However, the existing bump lock uses a lever at one end of the handle to push one of the movable blocks of the clamping mechanism, and the movable block drives the clamping mechanism to unfold. During production and installation, it is necessary to distinguish between left and right. The handle can only be turned from one direction. Therefore, the handle and clamping mechanism need to be produced and installed in two directions, left and right, according to the actual installation. This causes inconvenience in installation and increases inventory pressure. Utility Model Content

[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 double-point latching lock, comprising a lock body 1, a latch plate 2 on the outer side of the lock body 1, and two clamping assemblies 3 inside the lock body 1. Each clamping assembly 3 includes two locking plates 31 (a) and two locking plates 32 (b), with the two locking plates 32 close to each other. As shown, the ends of the facing sides of the locking plates 31 and 32 abut against each other, and the ends of the locking plates 31 and 32 have abutting portions. The abutting portion of the locking plate 31 is located below the abutting portion of the locking plate 32. A space is provided between the locking plates 31 and 32. An elastic element 4 is provided, which can be implemented by a tension spring. One end of the elastic element 4 is connected to the a-lock piece 31, and the other end is connected to the lock body 1. The two b-lock pieces 32 are mutually connected and driven. A column 320 is provided on the side of the two b-lock pieces 32 facing the buckle plate 2. The middle part of the buckle plate 2 is rotatably connected to the lock body 1. Pushing blocks 20 for pushing the columns 320 are symmetrically arranged on the side of the buckle plate 2 facing the lock body 1. A rotating shaft 201 is provided in the middle of the buckle plate 2 and is rotatably connected to the lock body 1 through the rotating shaft 201. The two pushing blocks 20 are symmetrically arranged on both sides of the buckle plate 2 facing the clamping assembly 3 with the rotating shaft 201 as the center. It also includes a socket 5, which includes two inserts 55. The socket 5 is installed on the outer frame. The socket 5 and the lock body 1 form a complete lock set. This belongs to the existing bump lock structure. It should be noted that the lock body 1 is provided with two clamping components 3, and the socket 5 is provided with two inserts 55. The inserts 55 correspond one-to-one with the clamping components 3.

[0020] This utility model discloses a universal double-point contact lock. It features two pushing blocks 20 on the buckle plate 2 and uprights 320 on the two b-lock plates 32. When the user moves the buckle plate 2, the pushing blocks 20 push the corresponding uprights 320, causing the corresponding b-lock plates 32 to unfold. The two b-lock plates 32 are interconnected; when one b-lock plate 32 unfolds, the other also unfolds. Furthermore, the a-lock plate 31 abuts against the b-lock plates 32. The unfolding of the b-lock plate 32 simultaneously pushes the a-lock plate 31 open, allowing the a-lock plate 31 and b-lock plate 32 to unfold together, thereby driving the a-lock plate 31 and b-lock plate 32 to move. The locking plates 32 unfold with each other, eliminating the need to distinguish between left and right during production and installation, thus improving installation convenience and reducing inventory pressure. Further explanation: the two b-locking plates 32 are interconnected and abut against their corresponding a-locking plates 31. When a b-locking plate 32 is pushed open, it causes the abutting a-locking plate 31 to unfold. Simultaneously, the unfolding of the a-locking plate 31 stretches the elastic element 4. Furthermore, due to the connection with the elastic element 4, the a-locking plate 31 automatically resets when the push from the b-locking plate 32 is removed. The reset of the a-locking plate 31 simultaneously pushes the abutting b-locking plate 32 to reset, achieving the effect of the b-locking plate 32 pushing the a-locking plate 31 to unfold, and the reset of the a-locking plate 31 causing the b-locking plate 32 to reset together.

[0021] Specifically, the lock body 1 is provided with a connecting post 41 for connecting the elastic element 4. The connecting post 41 is located between the a locking piece 31 and the b locking piece 32. The lock body 1 is elastically connected to the a locking piece 31 by the connecting post 41, and the connecting post 41 needs to be located between the a locking piece 31 and the b locking piece 32. It is mainly used to reset the a locking piece 31 after it is pushed open.

[0022] Both locking piece a 31 and locking piece b 32 are rotatably connected to the lock body 1. This is an existing bump lock structure. Based on this, the push block 20 has an inclined surface, and the end of the column 320 is spherical. The column 320 abuts against the inclined surface through this end. The push block 20 uses the inclined surface to push the column 320 to unfold. It should be noted that the two columns 320 are located between the two push blocks 20. The side of the two push blocks 20 facing each other is an inclined surface. The two push blocks 20 abut against the corresponding columns 320 through the inclined surface.

[0023] Specifically, the lock body 1 has a groove 100, and the buckle plate 2 is disposed in the middle of the groove 100. Placing the buckle plate 2 in the middle of the groove 100 makes the lock body 1 look more harmonious and facilitates the user to pry the buckle plate 2 from top or bottom. Space is reserved on both sides of the groove 100 to facilitate the user's prying of the buckle plate 2. The clamping component 3 is disposed inside the lock body 1. The bottom of the groove 100 has an opening 102, through which the column 320 protrudes into the groove 100 and cooperates with the push block 20. The opening 102 is preferably C-shaped, as its shape better matches the swinging motion of the b-lock plate 32. That is, while the b-lock plate 32 swings, the column 320 slides along the opening 102, which helps stabilize the swinging motion of the b-lock plate 32.

[0024] Specifically, both b-locking plates 32 have intermeshing transmission teeth on their facing sides. The two b-locking plates 32 are driven by the intermeshing transmission teeth, so that when one b-locking plate 32 is pushed open by the push block 20, it drives the other b-locking plate 32 to unfold.

[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.
