Description

Technical Field

[0001] This utility model relates to the field of monitoring and storage equipment technology, and in particular to a small-sized anti-theft mechanical lock. Background Technology

[0002] For devices such as automotive hard drive enclosures, a flip-top cover is typically used to seal the enclosure. These enclosures usually employ a locking mechanism to lock the cover and enclosure together, providing a sealed environment and security. In existing technology, this typically involves inserting a key into a keyhole and turning it to rotate the inner bolt. The bolt engages a locking groove, or is blocked by a side wall, thus restricting the movement of the cover and achieving a locking effect. However, due to the small overall structure of the enclosure, existing technologies generally use small lock cylinders. These small lock cylinders are relatively simple and flimsy, making them easy to pry open and disassemble with tools, resulting in weak anti-theft capabilities.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a small-sized anti-theft mechanical lock.

[0005] The technical solution of this utility model is as follows: A small-sized anti-theft mechanical lock is provided, including: a lock head, a lock cylinder movably embedded in the lock head, and a lock tongue connected and fixed to the lock cylinder. The inner side of the lock head is provided with a latch corresponding to the lock cylinder, and the lock cylinder is provided with an L-shaped groove corresponding to the latch. The L-shaped groove extends around the side wall of the lock cylinder, and the latch moves along the L-shaped groove.

[0006] Furthermore, the lock head and the lock tongue are clamped to both sides of the panel to be locked.

[0007] Furthermore, the bolt is secured to the lock cylinder by screws.

[0008] Furthermore, the lock cylinder is provided with a Z-shaped buckle at one end facing the lock tongue, and the lock tongue is provided with a positioning groove corresponding to the Z-shaped buckle. The Z-shaped buckle is embedded in the positioning groove, and the end of the Z-shaped buckle is pressed against the end face of the lock tongue.

[0009] Furthermore, the outer side of the lock head is provided with several elastic locking blocks.

[0010] Furthermore, the keyhole of the lock cylinder adopts a stepped structure.

[0011] Using the above-described solution, this utility model inserts the latch into the transverse end of the L-shaped groove of the lock cylinder. Then, the latch is fixed to the lock cylinder, tightening and securing it to prevent rotation, thus achieving the installation of the anti-theft mechanical lock. By fixing the latch to the lock cylinder, the rotation of the lock cylinder is restricted, preventing it from rotating back to its initial insertion angle and thus limiting its unscrewing. This prevents the lock cylinder from being forcibly pried open, providing anti-theft and anti-tampering protection. Furthermore, the anti-theft mechanical lock provided by this utility model has a compact and small overall structure, making it suitable for use on products of different sizes and specifications, achieving effective anti-theft security.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Please see Figures 1 to 3 This utility model provides a small-sized anti-theft mechanical lock, including: a lock head 1, a lock cylinder 2 movably embedded in the lock head 1, and a lock tongue 3 connected and fixed to the lock cylinder 2. The inner side of the lock head 1 is provided with a latch 11 corresponding to the lock cylinder 2, and the lock cylinder 2 is provided with an L-shaped groove 21 corresponding to the latch 11. The L-shaped groove 21 extends around the side wall of the lock cylinder 2, and the latch 11 moves along the L-shaped groove 21.

[0019] When installing the mechanical lock, first install the lock cylinder 1 on the panel 6 to be locked. Then, align the L-shaped groove 21 of the lock cylinder 2 with the latch 11 on the inside of the lock cylinder 1, push the lock cylinder 2 into the lock cylinder 1, so that the latch 11 enters the L-shaped groove 21, and rotate the lock cylinder 2 so that the latch 11 enters the lateral end of the L-shaped groove 21 around the lock cylinder 2. Then, fix the bolt 3 to the lock cylinder 2 to tighten and fix the lock cylinder 2, preventing the lock cylinder 2 from rotating, thus completing the installation of the anti-theft mechanical lock. By fixing the bolt 3 to the lock cylinder 2, the rotation direction of the lock cylinder 2 can be restricted, thereby preventing the lock cylinder 2 from rotating to the initial insertion angle, which restricts the lock cylinder 2 from being unscrewed, and thus prevents the lock cylinder 2 from being forcibly pried open, providing anti-theft and anti-tampering functions.

[0020] In some embodiments, L-shaped grooves 21 are provided on both sides of the lock cylinder 2, and two sets of latches 11 are provided on the lock head 1 respectively, so that the latches 11 on both sides can be engaged with the L-shaped grooves 21 respectively, thereby improving the stability of the lock cylinder 2 in the lock head 1.

[0021] In some embodiments, after the latch 11 enters the L-shaped groove 21, the angle range of the rotation of the lock cylinder 2 is 135°, which effectively prevents the latch 11 from disengaging from the L-shaped groove 21 of the lock cylinder 2, thus achieving a stable assembly effect.

[0022] In some embodiments, the lock cylinder 1 and the bolt 3 are clamped to both sides of the panel 6 to be locked. By pressing the panel 6 together with the lock cylinder 1 and the bolt 3, the force and feel of the locking and unlocking states can be controlled, thereby improving safety in the event of forced disassembly.

[0023] In some embodiments, the bolt 3 is locked to the lock cylinder 2 by a screw 4, thereby ensuring the stability of the connection between the bolt 3 and the lock cylinder 2. At the same time, by adjusting the number of turns the screw 4 is screwed in, the force and feel of the locking and unlocking states can be adjusted.

[0024] In some embodiments, a Z-shaped latch 22 is provided at the end of the lock cylinder 2 facing the bolt 3, and a positioning groove 31 is provided on the bolt 3 corresponding to the Z-shaped latch 22. The Z-shaped latch 22 is embedded in the positioning groove 31, and the end of the Z-shaped latch 22 is pressed against the end face of the bolt 3. The Z-shaped latch 22 is used to position and fix the lock cylinder 2 and the bolt 3, thereby improving the stability of the connection between the lock cylinder 2 and the bolt 3.

[0025] In some embodiments, a plurality of elastic locking blocks 12 are provided on the outer side of the lock head 1. When the lock head 1 is installed on the panel 6 to be locked, the elastic locking blocks 12 press against the inside of the mounting holes of the panel 6, thereby improving the stability of the lock head 1 in the installed state. In some embodiments, a groove is provided on the inner wall of the mounting holes of the panel 6 corresponding to the elastic locking blocks 12. The elastic locking blocks 12 are embedded in the groove, thereby preventing the lock head 1 from rotating, thus effectively improving the anti-theft and anti-tampering effect of the anti-theft mechanical lock.

[0026] In some embodiments, the keyhole of the lock cylinder 2 adopts a stepped structure 23, thereby being compatible with different types of keys 5 for unlocking, providing convenience for users. In the prior art, mechanical locks configured on products such as hard drive enclosures generally use either a plastic key 51 or a metal key 52 for unlocking and locking. In this embodiment, please refer to... Figures 2 to 5By setting a stepped structure 23 and aligning the front ends of the corresponding plastic key 51 and metal key 52 with the upper and lower step positions respectively, the tooth profiles of the two keys 5 are matched, making it easy to accommodate the unlocking needs of the two keys 5 and providing users with more diverse choices.

[0027] In summary, this utility model involves inserting the lock cylinder into the lateral end of the L-shaped groove via a latch. The latch is then fixed to the lock cylinder, tightening and securing it to prevent rotation. This achieves the installation of the anti-theft mechanical lock. By fixing the latch to the lock cylinder, the direction of rotation is restricted, preventing the cylinder from rotating to its initial insertion angle and thus limiting its unscrewing. This prevents the lock cylinder from being forcibly pried open, providing anti-theft and anti-tampering protection. Furthermore, the overall structure of the anti-theft mechanical lock provided by this utility model is compact and small, suitable for use on products of various sizes, providing effective anti-theft security.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
