A locking groove 103 is provided on the lower right side of 101. Specifically, the guide groove 101 provides precise guidance for the lateral sliding of the sliding lock cylinder 2, avoiding deviation and jamming. The sliding groove 102 is adapted to the sliding block 201 to further limit the trajectory of the sliding lock cylinder 2 and ensure stable lateral movement. The locking groove 103 provides installation space for the anti-loosening pin 3 and can work with the anti-loosening pin 3 to limit the sliding lock cylinder 2 and prevent accidental disengagement. The multiple grooves work together to provide structural support for the subsequent assembly and stable operation of the locking components, ensuring the initial assembly accuracy and operational stability.

[0018] The sliding lock cylinder 2 is U-shaped and horizontally arranged. The two right ends of the sliding lock cylinder 2 are slidably connected to the guide groove 101 of the fixed base 1. A sliding block 201 is fixedly connected between the two left ends of the sliding lock cylinder 2. The sliding block 201 is slidably connected to a sliding groove 102 inside the fixed base 1.

Specifically, the sliding block 201 cooperates with the sliding groove 102, superimposed on the guide groove 101, to lock the sliding lock cylinder. The limiting at both ends forms a double guide, ensuring the straightness of the lateral sliding and avoiding deviation that affects the locking dock. The support spring 202 pushes the sliding block 201 with elastic force, causing the sliding lock cylinder 2 to automatically reset to the pre-locked state, eliminating the need for manual reset and improving the convenience of operation. When locked, it can maintain the tight fit between the sliding lock cylinder 2 and the locking seat 4, offsetting the gap of the body vibration and preventing loosening. The anti-loosening groove 203 can be engaged with the anti-loosening pin 3, which limits the lateral sliding lock cylinder 2 and avoids external force displacement. It provides a matching structure for the function of the anti-loosening pin 3. The locking groove 204 cooperates with the locking button 5. The equidistant locking groove 204 can enhance the locking effect of the sliding lock cylinder 2 and achieve first-level locking, preventing the sliding lock cylinder 2 from disengaging from the locking seat 4.

[0019] The anti-loosening pin 3 is slidably connected to the locking groove 103 inside the fixed base 1. The locking groove 103 is L-shaped and engages with the anti-loosening groove 203 at the bottom of the upper right side of the sliding lock cylinder 2. A trigger button 301 is fixedly installed on the front side wall of the anti-loosening pin 3. The trigger button 301 is slidably connected to the front side wall of the fixed base 1. Two anti-loosening springs 302 are symmetrically installed at the bottom of the anti-loosening pin 3. Specifically, the anti-loosening pin 3 engages with the anti-loosening groove 203 to build a secondary anti-loosening defense line after the primary locking. Even if the locking button 5 fails or is subjected to vibration, it will still... It can prevent the sliding lock cylinder 2 from loosening, greatly improving the locking security. The "L"-shaped locking groove 103 restricts the anti-loosening pin 3 to slide only vertically, ensuring accurate engagement / disengagement from the anti-loosening groove 203, avoiding deviation failure, and ensuring the reliability of anti-loosening. The anti-loosening spring 302 continuously pushes the anti-loosening pin 3, keeping it in the engaged position. It can maintain the anti-loosening state without additional external force, reducing the difficulty of operation and enhancing stability. The trigger button 301 makes it easy to manually press down the anti-loosening pin 3 to quickly release the anti-loosening, and the hidden design reduces the risk of accidental activation, balancing the anti-loosening effect and convenience.

[0020] The locking seat 4 has two symmetrically arranged lock hole slots 401 on its left side wall. Two locking buttons 5 are slidably connected to the opposite side walls of the two lock hole slots 401. The right end of the sliding lock cylinder 2 is inserted into the lock hole slot 401, and the locking buttons 5 are engaged in the locking grooves 204 on the outer walls of the right sides of the sliding lock cylinder 2. The outer walls of the rotary lock cylinder 6 have symmetrically arranged sliding fins 601 on their upper and lower sides. The sliding fins 601 are slidably connected to a sliding groove inside the locking seat 4. The left side of the sliding groove is a circular groove, and the left side of the rotary lock cylinder 6 is elliptical, with its highest points resting on the locking buttons 5. A return spring 602 is fixedly connected to the middle of the left side wall of the rotary lock cylinder 6. Specifically, the lock hole slots 401 provide a precise insertion channel for the right end of the sliding lock cylinder 2, ensuring coaxial alignment and preventing locking failure due to deviation, and supporting the sliding... Lock cylinder 2 meets the requirements to ensure initial locking accuracy. Locking button 5 engages with locking groove 204, directly restricting the axial displacement of sliding lock cylinder 2 to achieve primary locking. Multiple locking grooves 204 further enhance the locking effect. The elliptical structure of rotating lock cylinder 6 initially presses against locking button 5 to prevent accidental retraction and maintain primary locking stability. Sliding fin 601 cooperates with the slide groove to guide the sliding of rotating lock cylinder 6, and the left circular groove of the slide groove provides rotational space to ensure smooth unlocking. After unlocking, return spring 602 pushes rotating lock cylinder 6 to reset, causing the elliptical structure to re-press against locking button 5, automatically restoring locking and improving convenience. Even when not unlocked, it maintains a pressing force to solidify the primary locking effect. Together with anti-loosening pin 3 for secondary anti-loosening, it forms a complete locking-unlocking system, ensuring the safe and stable locking of the compartment.

[0021] The specific usage and function of this embodiment are as follows: When using this anti-loosening safety locking structure, during locking, the support spring 202 in the fixed seat 1 initially pushes the sliding block 201, placing the sliding lock cylinder 2 in the pre-locked position. Manually push both ends of the right side of the sliding lock cylinder 2, causing it to slide laterally along the guide groove 101 and sliding groove 102 of the fixed seat 1 until the right end of the sliding lock cylinder 2 is inserted into the lock hole groove 401 of the locking seat 4. At this time, the locking button 5 in the locking seat 4 automatically engages with the locking groove 204 of the sliding lock cylinder 2 under the pressure of the elliptical structure of the rotating lock cylinder 6, completing the first-level locking. Simultaneously, the anti-loosening pin 3 in the fixed seat 1 moves vertically upward along the locking groove 103 under the elastic force of the anti-loosening spring 302, engaging with the anti-loosening groove 203 of the sliding lock cylinder 2, forming the second-level anti-loosening, achieving complete locking. During unlocking... Insert the key into the right side of the rotary lock cylinder 6, push the rotary lock cylinder 6 to the left and compress the return spring 602, so that the sliding fin 601 slides along the groove of the locking seat 4 to the left circular groove. Rotate the key to drive the rotary lock cylinder 6 to rotate, and its elliptical structure releases the pressure on the locking button 5. The locking button 5 disengages from the locking groove 204, releasing the first-level lock. Then press the trigger button 301 of the anti-loosening pin 3, so that the anti-loosening pin 3 moves down along the locking groove 103 and compresses the anti-loosening spring 302, disengaging from the anti-loosening groove 203 and releasing the second-level anti-loosening. At this time, the support spring 202 pushes the sliding block 201, driving the sliding lock cylinder 2 to reset along the guide groove 101 and the sliding groove 102. The right end of the sliding lock cylinder 2 disengages from the lock hole groove 401 of the locking seat 4. At the same time, the rotary lock cylinder 6 resets under the action of the return spring 602, completing the unlocking.

[0022] Example 2: The right side wall of the fixed seat 1 is integrally formed with three positioning bosses, and the left side wall of the locking seat 4 is provided with matching positioning grooves. The positioning bosses and positioning grooves are in clearance fit. The positioning bosses and positioning grooves are in fit to provide a quick alignment reference when the fixed seat 1 and the locking seat 4 are installed, so as to avoid the sliding lock cylinder 2 being unable to be inserted into the lock hole slot 401 due to docking misalignment, thus improving assembly efficiency.
