Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a general-purpose lock with adjustable bolt extension length. Background Technology

[0002] Current drawer locks are a type of mortise lock, commonly used in drawers, filing cabinets, and small storage cabinets. The main structure and function of this type of lock are as follows: the lock cylinder is the cylindrical component at the top of the lock; inserting a key and turning it controls the extension and retraction of the bolt, enabling locking and unlocking; the bolt is a square movable component that extends to lock the cabinet body to prevent the drawer from being pulled open, and retracts to open the drawer when unlocking; the mounting plate has holes for screws to fix it to the drawer or cabinet body for installing the lock. It is easy to install, has universal specifications, and is suitable for a wide range of scenarios, making it a general-purpose lock. Currently, most of these locks have a fixed, one-piece bolt structure. However, due to the diversity of furniture door panels, cabinet thicknesses, and lock specifications, compatibility issues can easily arise. When facing thick door panels or cabinets, the bolt length may be insufficient, leading to an unstable lock and reduced anti-theft performance. When facing thin door panels or cabinets, the bolt may extend too far, exceeding the length required for normal locking. This can cause unnecessary hard contact with the internal structure of the cabinet (such as side panels and the area around the lock), resulting in jamming, component wear, and even cabinet cracking and lock damage. This not only affects the user experience but also shortens the lifespan of the furniture and locks. Utility Model Content

[0003] The purpose of this utility model is to address the problem that most drawer locks currently use a one-piece fixed structure for the bolt, which has poor adaptability due to the variety of furniture door panels, cabinet thicknesses, and lock specifications: when the door panel is thick, the bolt is too short, resulting in an unstable lock and reduced anti-theft performance; when the door panel is thin, the bolt is too long, which easily makes hard contact with the cabinet, causing jamming, wear, and damage, affecting the user experience and shortening the lifespan. The present invention proposes a universal lock with an adjustable bolt extension length.

[0004] The technical solution of this utility model is: a universal lock with adjustable bolt extension length, including a lock body and a bolt, and further including: a plurality of adjustable splicing blocks installed sequentially at the end of the bolt, wherein the adjustable splicing blocks are connected by a splicing structure; one of the adjustable splicing blocks has a locking block at the end away from the bolt, and the locking block has a fixing mechanism installed inside for locking the adjustable splicing block.

[0005] Optionally, one end of each adjusting splicing block is fixedly connected to a positioning plug, and the end of each adjusting splicing block away from the positioning plug is provided with a second slot for the positioning plug to be inserted, and the end of the locking tongue near the adjusting splicing block is provided with a first slot for the positioning plug to be inserted.

[0006] Optionally, the fixing mechanism includes a pair of spiral holes at the end of the latch, and each of the adjusting splice blocks has a pair of first through holes corresponding to the spiral holes. The lock block has a pair of third through holes corresponding to the first through holes and the spiral holes. The third through holes are provided with screws that can pass through the first through holes and are spirally connected to the spiral holes.

[0007] Optionally, the latch is provided with a limiting groove to prevent the latch from sliding horizontally.

[0008] Optionally, the lock body is further provided with a lock cylinder, and the lock body is provided with multiple mounting holes.

[0009] Optionally, each of the third through holes has a groove inside for the screw end to be inserted.

[0010] Optionally, the pair of spiral holes, screws, third through holes and first through holes are all symmetrically arranged with the second slot as the center.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] This utility model uses a combination of components such as the lock body, lock tongue, adjusting splicing block, and lock block, and utilizes spiral holes, slots, through holes, and screws to achieve splicing and adjustment, so that the length of the lock tongue can be adjusted as needed. This solves the compatibility problem caused by the variety of furniture door panels, cabinet thicknesses, and lock buckle specifications of integrated lock tongues, and avoids the situation that the lock is not secure when it is too short or that it damages the cabinet when it is too long, thereby improving the user experience and extending the service life.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0023] like Figures 1 to 3As shown, the universal lock with adjustable bolt extension length proposed in this utility model includes a lock body 1 and a bolt 2. The lock body 1 also has a lock cylinder 11, which is installed on the lock body 1. Inserting a key and turning it controls the extension and retraction of the bolt 2, realizing the locking and unlocking functions. The lock body 1 has multiple mounting holes 12, which are used to fix the lock to furniture such as drawers and cabinets using screws. The bolt 2 has a limiting groove 13 that locks the bolt 2 horizontally, restricting its horizontal sliding trajectory and ensuring stable extension and retraction. Multiple adjusting splicing blocks 21 are sequentially installed at the end of the bolt 2. These adjusting splicing blocks 21 are connected in a splicing structure, increasing the overall length of the bolt 2 and realizing the adjustment of the bolt 2's length. All the adjusting splicing blocks 21 are connected by a splicing structure; one of the adjusting splicing blocks 21 has a locking block 22 at the end away from the locking tongue 2. The locking block 22 is located at the end of the adjusting splicing block 21 away from the locking tongue 2, and has a fixing mechanism installed inside to lock the adjusting splicing block 21 and stabilize the splicing structure of the locking tongue 2.

[0024] Among them, such as Figure 2 , Figure 3 As shown, each adjusting splicing block 21 has a fixedly connected positioning insert 212 at one end. The positioning insert 212 is fixedly connected to one end of the adjusting splicing block 21 and can be inserted into the first slot 202 of the locking tongue 2 or the second slot 211 of other adjusting splicing blocks 21 to achieve positioning splicing between components. Each adjusting splicing block 21 has a second slot 211 for the positioning insert 212 to be inserted at the end away from the positioning insert 212. The second slot 211 is located at the end of the adjusting splicing block 21 away from the positioning insert 212, allowing the positioning insert 212 of other adjusting splicing blocks 21 to be inserted, achieving docking between the adjusting splicing blocks 21. The locking tongue 2 has a first slot 202 for the positioning insert 212 to be inserted at the end near the adjusting splicing block 21, allowing the positioning insert 212 of the adjusting splicing block 21 to be inserted, achieving initial docking between the locking tongue 2 and the adjusting splicing block 21.

[0025] In addition, such as Figure 2 , Figure 3As shown, the locking block 22 has a fixing mechanism installed inside for locking the adjusting splicing block 21. The fixing mechanism includes a pair of spiral holes 201 at the end of the latch 2. The spiral holes 201 are located at the end of the latch 2 and cooperate with the screw 203 to fix the adjusting splicing block 21 and the locking block 22 by threaded connection. Each adjusting splicing block 21 has a pair of first through holes 210 corresponding to the spiral holes 201. The first through holes 210 are located on the adjusting splicing block 21 and correspond to the spiral holes 201 and the third through holes 220, allowing the screw 203 to pass through so that the screw 203 can fix the adjusting splicing block 21 to the latch 2 and the locking block 22. The locking block 22 has a pair of third through holes 220 corresponding to the first through hole 210 and the spiral hole 201. The third through holes 220 are opened on the locking block 22 and correspond to the first through hole 210 and the spiral hole 201, so that the screw 203 can pass through and connect the locking block 22, the adjusting splicing block 21 and the locking tongue 2.

[0026] It is worth noting that, for example Figures 1 to 3 As shown, a screw 203 is provided inside the third through hole 220, which passes through the first through hole 210 and is then spirally connected to the spiral hole 201. The screw 203 passes through the third through hole 220 of the locking block 22 and the first through hole 210 of the adjusting splicing block 21, and is then spirally connected to the spiral hole 201 of the locking tongue 2. This is used to lock the adjusting splicing block 21 and the locking block 22, and to fix the overall length of the locking tongue 2. The interior of each third through hole 220 has a groove 221 for the end of the screw 203 to be inserted. The groove 221 is located inside the third through hole 220 to allow the end of the screw 203 to be inserted, preventing the end of the screw 203 from protruding, ensuring the surface of the locking block 22 is flat, and enhancing the fixing effect. The pair of spiral holes 201, screw 203, third through hole 220, and first through hole 210 are all symmetrically arranged with the second slot 211 as the center.

[0027] In this embodiment, when using a universal lock with adjustable bolt extension length, the bolt length adjustment is achieved through the cooperation of various components. First, the positioning insert 212 at the end of the first adjusting splice block 21 is inserted into the first slot 202 at the end of the bolt 2. When splicing multiple adjusting splice blocks 21, simply insert the positioning insert 212 at the end of the adjusting splice block 21 into the second slot 211 within the corresponding adjusting splice block 21. Then, the corresponding adjusting splice blocks 21 are spliced ​​according to the length of the bolt 2. Next, the lock block 22 is placed at the end of the adjusting splice block 21 away from the bolt 2. Then, a pair of screws 203 are sequentially passed through the third through hole 220 and the first through hole 210 on the lock block 22 and the adjusting splice block 21. Finally, the end of the screw 203 is inserted into the corresponding spiral hole 201. Since the screw 203 and the spiral hole 201 are spirally connected, the screw 203 is tightened so that its end is engaged in the groove 221, thereby fixing the length of the spliced ​​bolt 2. The spliced ​​latch 2 can be adapted to the thickness of the door panel or cabinet to extend in a suitable length, which avoids the problem of the latch being too short and not locking properly, and also prevents the latch from being too long and damaging the cabinet, thus improving its universal compatibility.
