[0022] Example 1:

[0023] Please see Figures 1-4This utility model discloses a quick-release anti-loosening latch, comprising a latch seat assembly 1, a latch assembly 2, and an anti-loosening component 3. The front end of the latch seat assembly 1 is slidably connected to the latch assembly 2, and the front end of the latch assembly 2 is fixedly connected to the anti-loosening component 3. The latch seat assembly 1 also includes a lower latch seat 11, a threaded groove 12, a slot 13, a screw 14, an upper latch seat 15, and a sliding groove 16. The front end of the lower latch seat 11 is slidably connected to the latch assembly 2. The threaded groove 12 is located at both ends of the lower latch seat 11, and the slot 13 is located inside the front end of the lower latch seat 11. The lower latch seat 11 and the slot 13 provide the mounting base and sliding track for the latch, allowing the latch to move back and forth as a whole, realizing a preliminary quick-release function, facilitating installation and position adjustment. The screw 14 is threadedly connected to the lower latch seat 11 through the threaded groove 12. The upper latch seat 15 is located on the upper end of the lower latch seat 11, and the sliding groove 16 is located at both ends of the upper latch seat 15.

[0024] The locking assembly 2 includes a lower locking buckle 21, a locking groove 22, an upper locking buckle 23, a limiting block 24, a spring 25, and a limiting guide rod 26. The lower end of the lower locking buckle 21 is slidably connected to the lower locking buckle seat 11 through a slot 13. The lower locking buckle 21 has threaded grooves 12 at both ends, and the lower locking buckle 21 is threadedly connected to a screw 14 through the threaded grooves 12. The locking groove 22 is located on the left and right sides of the upper end of the lower locking buckle 21. The upper locking buckle 23 is fixedly connected to the front end of the upper locking buckle seat 15, and the lower end of the upper locking buckle 23 is slidably connected to the upper end of the lower locking buckle 21. The limiting block 24 is slidably connected to the upper locking buckle 21. At both ends of the 3rd section, the limiting buckle 24 is slidably connected to the lower buckle 21 through the buckle groove 22. The spring 25 is fixedly connected to the inside of the upper buckle 23. The spring 25 is fixedly connected to the upper end of the limiting buckle 24. The limiting guide rod 26 is fixedly connected to the upper end of the limiting buckle 24. The setting of the limiting guide rod 26 greatly improves the working stability of the spring 25, preventing the spring 25 from bending, being unbalanced, or even jamming during compression and rebound, ensuring the smoothness and long-term reliability of the locking action. The limiting guide rod 26 is placed inside the spring 25 and is slidably connected to the inside of the upper buckle 23.

[0025] This utility model provides an improved quick-release anti-loosening lock, the working principle of which is as follows:

[0026] First, when using this lock, install it into the designated enclosure.

[0027] Secondly, when the latch is needed, the upper latch 23 can be slidably aligned with the lower latch 21 along with the upper latch seat 15. At this time, the spring 25 inside the upper latch 23 is in its natural state, and its elasticity pushes the limiting latch block 24 to extend inward. When the upper latch 23 and the lower latch 21 slide to the corresponding position, the limiting latch block 24 will automatically engage with the latch groove 22 at the upper end of the lower latch 21, achieving quick engagement. At the same time, the limiting guide rod 26, which is placed inside the spring 25 and slidably connected to the upper latch 23, will limit the deformation direction of the spring 25, ensuring that the limiting latch block 24 engages precisely and avoids displacement.

[0028] Example 2:

[0029] Please see Figures 1-4 Compared to Embodiment 1, this utility model provides a quick-release anti-loosening lock, which further includes the following: the anti-loosening component 3 includes a rotating base 31, a loosening fixing block 32, a pull bar 33, a magnetic positive pole 34, a magnetic negative pole 35, and a limiting loosening block 36. The rotating base 31 is fixedly connected to the front end of the upper lock 23, the upper end of the loosening fixing block 32 is rotatably connected to the rotating base 31, and the pull bar 33 is fixedly connected to the lower side of the front end of the loosening fixing block 32. The pull bar 33 provides a clear and easy-to-apply operating point, allowing the user to easily hook and pull it with their fingers to unlock the anti-loosening mechanism. The magnetic positive pole 34 is fixedly connected to the lower side of the rear end of the loosening fixing block 32, and the front end of the magnetic negative pole 35 is magnetically connected to the rear end of the magnetic positive pole 34. The limiting loosening block 36 is fixedly connected to the front end of the lower lock 21, and the magnetic negative pole 35 is fixedly connected to the front end of the lower lock 21. The middle part of the limiting loosening block 36 is slidably connected to the loosening fixing block 32.

[0030] In this embodiment:

[0031] When it is necessary to prevent the latch from loosening, after the latch is engaged, first rotate the loosening fixing block 32 with the rotating seat 31 as the fulcrum, so that it slides and engages with the limiting loosening block 36 at the front end of the lower latch 21. This mechanical structure restricts the forward and backward displacement of the lower latch 21 and its upper components. At the same time, the magnetic positive pole 34 at the rear end of the loosening fixing block 32 will be tightly attracted to the magnetic negative pole 35 fixed at the front end of the lower latch 21, further reinforcing it with magnetic force and preventing the latch from accidentally loosening due to vibration or external force. To disassemble, simply reverse the operation: first, pull the pull bar 33 to make the loosening fixing block 32 rotate around the rotating seat 31, so that the magnetic positive pole 34 and the magnetic negative pole 35 are separated, and at the same time the loosening fixing block 32 is disengaged from the limiting loosening block 36, thus releasing the anti-loosening restriction; then press the limiting buckles 24 on both sides to compress the spring 25 and make the limiting buckles 24 disengage from the buckle groove 22, thus releasing the locking assembly; finally, unscrew the screw 14 and slide the lower locking buckle 21 out of the slot 13 of the lower locking seat 11 to complete the quick disassembly.

[0032] This utility model provides an improved quick-release anti-loosening latch. By setting a sliding connection between the lower latch 21 and the latch seat and fixing it with screws, quick disassembly and maintenance are achieved. The latch assembly 2 is composed of a spring 25, a limiting guide rod 26 and a limiting latch block 24 to form an adaptive locking mechanism, which ensures tightness and reliability when locked. The anti-loosening assembly 3 uses a rotating seat 31 and a magnetically attracted fixing block to magnetically assist positioning and physically block the limiting release block 32 when locked, forming an efficient mechanical anti-loosening barrier, which effectively resists accidental unlocking caused by vibration.
