[0002] At present, when two or more (including this number) devices need to be assembled together for stacking, conventional screws and non-loose hand screws are commonly used for fastening. Conventional screws require special tools, and have defects such as easy loss of screws after disassembly and inconvenience in carrying tools. Especially for equipment used outdoors, due to outdoor conditions, it is impossible to carry too many disassembly and assembly tools or other auxiliary tools, resulting in the equipment being unable to be installed on site or being installed loosely. Hand-tightened non-loose screws require a certain amount of free space around them to facilitate the operation of staff. For small-sized equipment, there is a defect of insufficient space, and the efficiency of screw locking and unlocking operations is also relatively low. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Figures 1 to 9 An embodiment of the locking mechanism of the utility model is shown, which includes a mounting plate 2 arranged on a first device (not shown in the figure), and a locking pin 4 arranged on a second device 1. An elastic member 5 and a reciprocating locking plate 6 are provided on the side of the mounting plate 2 away from the second device 1. A locking hole 3 is provided on the mounting plate 2, and a locking groove 41 is provided at one end of the locking pin 4 and passes through the locking hole 3. A card groove 61 matching the locking groove 41 is provided on the locking plate 6, and the locking plate 6 abuts against the elastic member 5 so that the card groove 61 is inserted into the locking groove 41.

[0030] In the locking mechanism of this embodiment, the mounting plate 2 provided on the first device is provided with an elastic member 5 and a slidable locking plate 6, so that the operator only needs to press the elastic member 5 by moving the locking plate 6 and pass the locking pin 4 on the second device 1 through the locking hole 3 on the mounting plate 2. Once the locking plate 6 is loosened, the elastic member 5 automatically pushes the locking plate 6 so that its card slot 61 is accurately inserted into the locking groove 41 of the locking pin 4, and the assembly operation can be completed, thereby stably connecting the first device and the second device 1 to achieve self-locking. Through the automatic recovery characteristics of the elastic member 5, the locking plate 6 can quickly and accurately cooperate with the locking groove 41 of the locking pin 4, reducing the assembly time and improving the overall assembly efficiency. When the first device and the second device 1 need to be separated, the operator only needs to slide the locking plate 6 again to press the elastic member 5, thereby separating the card slot 61 from the locking groove 41, and then the locking pin 4 can be easily removed to complete the separation of the two devices, greatly reducing the difficulty of disassembly and assembly. Since the locking mechanism of this embodiment does not completely separate independent components, assembly problems caused by the loss of components are avoided, and the overall reliability is improved.

[0031] Further, in this embodiment, a mounting seat 21 is provided on the mounting plate 2, and a mounting groove 211 for accommodating the elastic member 5 is provided on the mounting seat 21. A guide rod 62 is provided on the side of the lock plate 6 close to the elastic member 5, and the guide rod 62 extends into the mounting groove 211. The elastic member 5 is preferably a coil spring, and one end of the coil spring is sleeved on the guide rod 62. The operator moves the lock plate 6 to press the elastic member 5. When the guide rod 62 abuts against the bottom wall of the mounting groove 211 and cannot move any further, it prompts the operator that the elastic member 5 has been compressed into place, and the lock plate 6 will no longer block the lock hole 3. If the first device and the second device 1 need to be combined at this time, after one end of the lock pin 4 passes through the lock hole 3 and the lock plate 6 is released, the slot 61 can be smoothly engaged with the locking groove 41 under the push of the coil spring; if the first device and the second device 1 need to be separated at this time, the lock pin 4 can be directly and smoothly withdrawn from the lock hole 3 to complete the separation. Specifically, in this embodiment, the diameter of the lock hole 3 is 4.6 mm, and from the locked state until the lock plate 6 compresses the coil spring by 2.3 mm, the lock plate 6 no longer blocks the lock hole 3, and when the lock plate 6 compresses the elastic member 5 by 4 mm, the guide rod 62 abuts against the bottom wall of the installation groove 211. Of course, in other embodiments, the diameter of the lock hole 3 and the distance between the guide rod 62 and the bottom wall of the installation groove 211 can be set as needed, and it is only necessary to ensure that after the guide rod 62 is relaxed after abutting against the bottom wall of the installation groove 211, the elastic member 5 can smoothly push the lock plate 6 to make its card slot 61 card into the locking groove 41.

[0032] Further, in this embodiment, the second device 1 is provided with two locking pins 4, preferably, the two locking pins 4 are provided on both sides of the second device 1, the mounting plate 2 is provided with two locking holes 3 and an elastic member 5, the locking plate 6 is provided with two locking grooves 41, and the two locking pins 4, the locking holes 3, the elastic member 5 and the locking grooves 41 are provided correspondingly. The locking at two locations enhances the connection strength between the first device and the second device 1 after locking, and ensures stability during use.

[0033] Further, in this embodiment, a connecting portion 22 is provided on the lock plate 6, and the connecting portion 22 is provided between the two locking grooves 41. A limiting portion 23 cooperating with the connecting portion 22 is provided on the mounting plate 2, and the limiting portion 23 is located between the lock hole 3 and the elastic member 5. After the lock plate 6 is released, the spiral spring resets and pushes the lock plate 6 to move, and stops moving when the connecting portion 22 on the lock plate 6 contacts the limiting portion 23. The limiting portion 23 can limit the moving distance of the lock plate 6, thereby enhancing the reliability in use.

[0034] Furthermore, in this embodiment, a shift block 7 is provided on the connecting portion 22, and a slide groove 24 for the shift block 7 to pass through is provided on the mounting plate 2. Preferably, a side of the shift block 7 passing through the mounting plate 2 is provided with an anti-skid pattern 71, and a side of the mounting plate 2 close to the second device 1 is provided with a shift block unlocking mark 25. The operator can follow the prompt of the shift block unlocking mark 25 and quickly push the shift block 7 in the correct direction, thereby operating the locking plate 6 to compress the coil spring. The anti-skid pattern 71 on the surface of the shift block 7 can increase friction and prevent slipping, which is more conducive to the operator pushing the shift block 7 and improves the convenience during use.

[0035] Furthermore, in this embodiment, a guide member 8 is provided on the mounting plate 2 and a guide channel is formed between the two, and the lock plate 6 is inserted into the guide channel. During the reciprocating movement of the lock plate 6, the guide member 8 guides and limits the lock plate 6, preventing the lock plate 6 from deflecting during the movement, ensuring that the card slot 61 can be smoothly inserted into the locking groove 41, and at the same time, the guide member 8 can prevent the lock plate 6 from being separated from the mounting plate 2 due to the force transmitted from the lock pin 4. The guide member 8 cooperates with the card slot 61 to lock the lock pin 4 on the mounting plate 2, thereby enhancing stability. Of course, in other embodiments, the guide member 8 can also be a guide groove, and the width of the guide groove opening is smaller than the width of the lock plate 6. The lock plate 6 is arranged in the guide groove to achieve the guiding and limiting functions.

[0036] Furthermore, in this embodiment, a plurality of guide members 8 are provided at intervals along the moving direction of the locking plate 6, thereby further enhancing the guiding and limiting functions.

[0037] The method of using the locking mechanism of this embodiment is as follows:

[0038] Initially, the first device and the second device 1 are in a separated state. First, push the shift block 7 to drive the lock plate 6 to slide and compress the coil spring until the guide rod 62 abuts against the bottom wall of the installation groove 211, maintain the position of the shift block 7 to keep the coil spring from loosening, then align the lock pin 4 on the second device 1 with the corresponding lock hole 3, pass one end of the lock pin 4 through the lock hole 3, and make the locking groove 41 and the card groove 61 of the lock plate 6 in the same plane, then release the shift block 7, and the coil spring pushes the lock plate 6 to move toward the lock pin 4 until the card groove 61 of the lock pin 4 is stuck in the locking groove 41, completing the assembly between the first device and the second device 1. When the first device needs to be separated from the second device 1, push the shift block 7 to drive the lock plate 6 to compress the coil spring, and when the lock plate 6 no longer blocks the lock hole 3, keep the position of the shift block 7 and move the lock pin 4 out of the lock hole 3, then release the shift block 7 to complete the disassembly between the first device and the second device 1.
