Description

Technical Field

[0001] This utility model relates to the field of locking technology, specifically a novel locking mechanism. Background Technology

[0002] During the assembly of the cabinet, two structural components need to be installed together, and then the two structures of the cabinet need to be locked together by latches.

[0003] Based on the above, the inventor has discovered that while there are many locks on the market, conventional locks are typically assembled by workers who fix both ends of the lock to the cabinet structural components to be assembled. The workers then attach the lock ring from one cabinet structural component to the lock clip on the other. This process significantly increases the workload for workers, and the ring is easily detached from the clip due to external forces. Consequently, the stability of the engagement between the two assembled cabinet components is poor, reducing the practicality of the device. Therefore, in view of this, the inventor has researched and improved the existing structure to provide a new type of lock, aiming to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a novel latch, including a protrusion, a concave block matched on the outer wall of the protrusion, a control mechanism on the inner wall of the protrusion and the concave block, a retraction mechanism on one side of the control mechanism, and the retraction mechanism being disposed on the inner wall of the protrusion.

[0006] The control mechanism includes:

[0007] A concave sliding plate has two sides that slide against the inner walls of a protrusion and a concave block, respectively. A horizontal column is fixed to the inner wall of the concave sliding plate, and an insert block is fixed to one side of the horizontal column. The bottom end of the insert block slides against the inner wall of the protrusion. Two toothed plates drive the outer wall of the concave sliding plate.

[0008] As a preferred embodiment of this utility model, a pull plate slides on the inner wall of the protrusion, and one side of the pull plate is fixed to the outer wall of the toothed plate.

[0009] In a preferred embodiment of this utility model, the horizontal column is disposed between two toothed plates and at the bottom end of the pull plate.

[0010] As a preferred embodiment of this utility model, the inner walls of both toothed plates are rotatably provided with a rotating shaft, and a round hole is provided on one side of each of the protrusions and concave blocks, with the inner walls of both round holes fitted onto the outer walls of the rotating shafts.

[0011] As a preferred embodiment of this utility model, the shrinking mechanism includes:

[0012] A spring damper is disposed on one side of the concave sliding plate, and the spring damper is disposed on the inner wall of the protrusion and the concave block.

[0013] As a preferred embodiment of this utility model, one end of the spring damper is fixed with a block, a square groove is provided on one side of the horizontal column, the inner wall of the square groove is fixed to the outer wall of the block, and the other side of the spring damper is fixed to the inner wall of the protrusion.

[0014] As a preferred embodiment of this utility model, the cross-sectional area of ​​the inner wall of the square groove is matched with the cross-sectional area of ​​the outer wall of the block.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution uses the matching installation of the outer wall of the protrusion and the inner wall of the concave block to install the latch on the cabinet assembly structure. The outer wall of the pull plate slides against the inner wall of the protrusion, thereby driving the toothed plate fixed to the pull plate to rotate on the outer wall of the rotating shaft. This causes the outer wall of the toothed plate to drive the outer wall of the concave slide plate, which in turn drives the concave slide plate to slide on the inner walls of the protrusion and concave block until the insert block fixed to the outer wall of the crossbar is inserted into the inner wall of the corresponding cabinet assembly structure and engaged. This reduces the workload of the operator and facilitates better engagement of the insert block with the inner wall of the groove on the external cabinet assembly structure. Therefore, it effectively and securely installs the two assembly structures on the cabinet, which is conducive to the normal use of the device.

[0017] 2. In this solution, by retracting the spring damper, the block fixed at one end is inserted into the inner wall of the square groove opened on one side of the horizontal column, which makes the block and the square groove stable in the installation. This makes it easier for the spring damper to be firmly installed with the horizontal column. When the pull plate drives the toothed plate to engage the insert with the groove inner wall of the external assembly cabinet structure, the spring damper's reset driving force will cause the insert to be firmly installed on the inner wall of the corresponding groove, effectively improving the performance of the device.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Example: Figures 1-4 As shown, this utility model discloses a novel latch, including a protrusion 1, a concave block 2 matched on the outer wall of the protrusion 1, a control mechanism 3 on the inner wall of the protrusion 1 and the concave block 2, and a retraction mechanism 4 on one side of the control mechanism 3. The retraction mechanism 4 is located on the inner wall of the protrusion 1, which facilitates the quick use of the latch to engage and install two assembly structures on the cabinet, thereby reducing the actual operation time of the staff and helping to strengthen the tightness of the connection between the two assembly structures of the cabinet, thus effectively improving the use effect of the device.

[0026] Control mechanism 3 includes:

[0027] The concave sliding plate 31 slides against the inner walls of the protrusion 1 and concave block 2 on both sides. A horizontal column 32 is fixed to the inner wall of the concave sliding plate 31, and an insert block 33 is fixed to one side of the horizontal column 32. The bottom end of the insert block 33 slides against the inner wall of the protrusion 1. Two toothed plates 34 drive the outer wall of the concave sliding plate 31. A pull plate 35 slides on the inner wall of the protrusion 1. One side of the pull plate 35 is fixed to the outer wall of the toothed plate 34. The horizontal column 32 is located between the two toothed plates 34 and at the bottom end of the pull plate 35. A rotating shaft 36 is rotatably mounted on the inner wall of each toothed plate 34. A round hole 37 is opened on one side of both the protrusion 1 and the concave block 2. The inner wall of each round hole 37 fits into the outer wall of the rotating shaft 36, which reduces the operator's workload and facilitates better engagement of the insert block 33 with the inner wall of the groove on the external cabinet assembly structure. Therefore, it effectively and securely installs the two assembly structures on the cabinet, which is conducive to the normal use of the device.

[0028] As attached Figure 2 , Figure 3 and Figure 4 As shown, the retraction mechanism 4 includes:

[0029] A spring damper 41 is disposed on one side of the concave sliding plate 31. The spring damper 41 is disposed on the inner wall of the protrusion 1 and the concave block 2. A square block 42 is fixed to one end of the spring damper 41. A square groove 43 is opened on one side of the cross column 32. The inner wall of the square groove 43 is fixed to the outer wall of the square block 42. The other side of the spring damper 41 is fixed to the inner wall of the protrusion 1. The cross-sectional area of ​​the inner wall of the square groove 43 is matched with the cross-sectional area of ​​the outer wall of the square block 42, so that the insert 33 can be inserted more firmly into the inner wall of the corresponding groove, so that the two assembly structures on the cabinet are stably installed.

[0030] Working principle: When in use, the spring damper 41 is contracted, so that the block 42 fixed at one end is inserted into the inner wall of the square groove 43 opened on one side of the crossbar 32, so that the block 42 and the square groove 43 are locked together for stability, and thus the spring damper 41 is firmly installed with the crossbar 32. The outer wall of the protrusion 1 is matched with the inner wall of the concave block 2 for installation. The latch is installed on the cabinet assembly structure. The outer wall of the pull plate 35 slides with the inner wall of the protrusion 1, thereby driving the toothed plate 34 fixed with the pull plate 35 to rotate on the outer wall of the rotating shaft 36. The spring damper 41 returns to its contraction force, so the outer wall of the toothed plate 34 is driven to drive the outer wall of the concave slide plate 31, thereby driving the concave slide plate 31 to slide on the inner wall of the protrusion 1 and the concave block 2 until the insert block 33 fixed with the outer wall of the crossbar 32 is inserted into the inner wall of the groove of the corresponding cabinet assembly structure for locking and installation. Therefore, the latch is used to quickly match and install the two structural components in the cabinet assembly.
