Description

Technical Field

[0001] The utility model relates to the technical field of single-sided locks, in particular to a single-sided lock for a cabinet door. Background Art

[0002] A one-sided lock is a special type of lock that has a key that can only open a specific lock cylinder and not other locks. This type of lock is often used in situations where highly personalized and customized security solutions are required, such as vehicle locks and house door locks. In these cases, each lock is equipped with a unique key that corresponds to it, which means that only the person holding the correct key can open the corresponding lock.

[0003] When the single-sided lock of the prior art needs to be disassembled for internal maintenance, multiple screws need to be removed to remove the cover plate, which is quite inconvenient. To solve the above problem, a single-sided lock for a cabinet door is provided. Utility Model Content

[0004] The purpose of the utility model is to provide a single-side lock for a cabinet door to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The cam is provided with a plurality of springs, each of which is provided with a plurality of springs, each of which is connected to a plurality of linking members, each of which is connected to a plurality of linking members.

[0008] Furthermore, a locking block is slidably connected to the inner wall of the slide groove, and a straight tooth is fixedly installed on one end of the locking block.

[0009] Furthermore, a connecting rod is installed on the inner wall of the bearing, and the connecting rod extends to the outer surface of the lock housing through the through groove, and a thread groove is formed on the peripheral side surface of the connecting rod.

[0010] Furthermore, a gear is fixedly mounted on the peripheral side surface of the connecting rod, the gear is spur-toothed and meshed, and a handle is threadedly connected to the outer surface of the thread groove.

[0011] Furthermore, a mounting plate is fixedly mounted on one side of the lock housing.

[0012] The utility model has the following beneficial effects:

[0013] (1) The utility model pinches the extension plate with two hands, so that the extension plate drives the slider to squeeze the spring to move inside the installation slot. The movement of the slider drives the clamping column to enter the interior of the installation slot, so that the clamping column releases the clamping of the clamping slot. Then, the cover plate is lifted up and removed from the connecting rod to complete the disassembly. The disassembly is convenient and quick, and the surface needs to remove multiple screws, which wastes maintenance time.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 - Figure 5 As shown, the utility model is a single-sided lock for a cabinet door, comprising a lock housing 1, an inner wall of the lock housing 1 is provided with a card slot 101, the number of the card slots 101 is fixed to four, a bearing 102 is fixedly installed on the inner bottom of the lock housing 1, a slide groove 103 is provided on the inner wall of the lock housing 1, and an installation component 2 is provided on the inner wall of the lock housing 1.

[0025] The mounting assembly 2 includes a cover plate 201, a through slot 202, an elongated slot 203, a mounting slot 204, a spring 205, a slider 206, an extension plate 207 and a clamping column 208. The outer surface of the cover plate 201 is provided with a through slot 202, the outer surface of the cover plate 201 is provided with an elongated slot 203, the number of the elongated slots 203 is fixed to four, the outer surface of the cover plate 201 is provided with a mounting slot 204, the number of the mounting slot 204 is fixed to four, the mounting slot 204 is connected to the elongated slot 203, a spring 205 is fixedly installed inside the mounting slot 204, a slider 206 is fixedly installed at one end of the spring 205, the slider 206 is slidably connected to the mounting slot 204, and the peripheral side of the slider 206 An extension plate 207 is fixedly installed, and the extension plate 207 extends to the outer surface of the cover plate 201 through the elongated slot 203. A clamping column 208 is fixedly installed at one end of the slider 206, and the clamping column 208 is clamped with the slot 101. By pinching the extension plate 207 with two hands, the extension plate 207 drives the slider 206 to squeeze the spring 205 to move inside the installation slot 204. The movement of the slider 206 drives the clamping column 208 to enter the interior of the installation slot 204, so that the clamping column 208 releases the clamping of the slot 101, and then the cover plate 201 is lifted up to be removed from the connecting rod 5 to complete the disassembly. The disassembly is convenient and quick, and it avoids the need to remove multiple screws, which wastes maintenance time.

[0026] The inner wall of the slide groove 103 is slidably connected with a locking block 3 , and one end of the locking block 3 is fixedly mounted with a spur tooth 4 .

[0027] A connecting rod 5 is installed on the inner wall of the bearing 102 . The connecting rod 5 extends to the outer surface of the lock housing 1 through the through slot 202 . A threaded groove 7 is formed on the peripheral side of the connecting rod 5 .

[0029] A mounting plate 9 is fixedly mounted on one side of the lock housing 1 .

[0030] When in use, first turn the handle 8 to drive the connecting rod 5 to rotate, and the connecting rod 5 drives the gear 6 to rotate. The rotation of the gear 6 drives the spur teeth 4 to move, and the movement of the spur teeth 4 drives the locking block 3 to slide on the inner wall of the slide groove 103, and the locking block 3 moves to the outer surface of the lock housing 1 to achieve the effect of locking. When disassembling and repairing, unscrew the handle 8 from the threaded groove 7, and then pinch the extension plate 207 with both hands to make the extension plate 207 drive the slider 206 to squeeze the spring 205 to move inside the installation groove 204, and the slider 206 moves to drive the clamping column 208 to enter the inside of the installation groove 204, so that the clamping column 208 releases the clamping of the clamping slot 101, and then lift up to remove the cover plate 201 from the connecting rod 5 to complete the disassembly. The disassembly is convenient and quick, and avoids the situation where it is necessary to remove multiple screws, which is more wasteful of maintenance time.
