DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solution of the present invention, but cannot be used to limit the protection scope of the present invention.

[0023] Example:

[0024] like Figures 1 to 4 As shown, the utility model provides a quick connection lock for an LED display screen cabinet, comprising a first connection seat 1 and a second connection seat 2. The first connection seat 1 and the second connection seat 2 have opposite ends provided with a first mounting plate 19 and a second mounting plate 20, respectively. The user can install the LED display screen on the connection lock through the first mounting plate 19, and then install the connection lock on the display screen cabinet through the second mounting plate 20. The first mounting plate 19 and the second mounting plate 20 make the connection between the LED display screen and the display screen cabinet faster and more convenient, which greatly saves installation time and labor costs, and effectively improves work efficiency. In addition, the user can also replace the first mounting plate 19 and the second mounting plate 20 that match the model of the LED display screen or the display screen cabinet, which effectively increases the versatility and compatibility of the connection lock.

[0025] A card block 4 is provided at one end corresponding to the first connecting seat 1 and the second connecting seat 2, wherein one group of card blocks 4 is located at the bottom of the first connecting seat 1, and the other group of card blocks 4 is located at the top of the second connecting seat 2. The first connecting seat 1 and the second connecting seat 2 are provided with first card slots 3 corresponding to each other, and the two groups of card blocks 4 are respectively clamped in the two groups of first card slots 3. Through this mutually clamped structure, the stability of the connection can be effectively increased, which can effectively prevent the first connecting seat 1 and the second connecting seat 2 from loosening or shifting during use, which effectively ensures the stability of the connecting lock.

[0026] like Figures 2 to 4As shown, a first movable block 6 and a second movable block 7 are clamped between the two groups of clamping blocks 4, and the two groups of clamping blocks 4 are correspondingly provided with fixing grooves 5. The first movable block 6 and the second movable block 7 are respectively clamped in the two groups of fixing grooves 5. When the user connects the first connecting seat 1 and the second connecting seat 2 together, the user can rotate the first movable block 6 and the second movable block 7 to make the first movable block 6 and the second movable block 7 cross-clamped in the two groups of fixing grooves 5, thereby fixing the first connecting seat 1 and the second connecting seat 2 together. Through this cross-clamping fixing method, the connection strength between the first connecting seat 1 and the second connecting seat 2 is effectively improved, which enables the connecting lock to effectively withstand external forces and vibrations from all directions, thereby ensuring the reliability and stability of the connecting lock.

[0027] The first movable block 6 and the second movable block 7 are each provided with a limiting rod 9 at the opposite end, and sliding grooves 8 are opened on both sides of the two groups of fixed grooves 5. The two ends of the two groups of limiting rods 9 are respectively clamped in multiple groups of sliding grooves 8. Through this structure, the first movable block 6 and the second movable block 7 can be effectively limited, which ensures that the first movable block 6 and the second movable block 7 can accurately perform cross-clamping actions during operation, and the structure also effectively prevents the first movable block 6 and the second movable block 7 from unnecessary shaking or deviation in the fixed groove 5, which effectively increases the stability of the connecting lock.

[0028] The contacting ends of the first movable block 6 and the second movable block 7 are both provided with magnets 10. When the two groups of blocks 4 are respectively inserted into the two groups of first slots 3, the first movable block 6 and the second movable block 7 will be connected through the two groups of magnets 10. The two groups of magnets 10 ensure that the first movable block 6 and the second movable block 7 can be rotated at the same time, which effectively ensures the stability of the connection and can also effectively avoid the separation problem caused by factors such as vibration and external force impact.

[0029] The first movable block 6 and the second movable block 7 are each provided with a connecting rod 11 at one end corresponding to the first movable block 6, and a group of connecting rods 11 are provided with a paddle 12 at one end. A plurality of buckles 14 are provided on the top of the second connecting seat 2, and a plurality of second slots 13 are provided on the paddle 12. The plurality of buckles 14 are respectively clamped in the plurality of second slots 13. When the user presses the connecting rod 11 to rotate the first movable block 6 and the second movable block 7, the connecting rod 11 can be effectively fixed by the fixing structure, which effectively ensures that the fixing structure can maintain its stable state, which effectively increases the stability and reliability of the coupling lock.

[0030] A telescopic rod 15 is provided between the other group of connecting rods 11 and the first connecting seat 1. A mounting groove 16 is provided on the first connecting seat 1. The telescopic rod 15 is clamped in the mounting groove 16. A movable plate 18 is provided between the telescopic rod 15 and the connecting rod 11. One end of the telescopic rod 15 is connected to the connecting rod 11 through the movable plate 18. A spring 17 is provided on the outer sleeve of the telescopic rod 15. When the user lifts the paddle 12, the spring 17 will release its squeezing force to assist the resetting of the telescopic rod 15. Through this structure, the user can release the fixed state without manual operation, which effectively simplifies the operation process and improves work efficiency. In addition, through its movable plate 18, it ensures that during the resetting process, the coordination between the various components is smoother, reducing the risk of failure caused by loose components or improper matching.

[0031] The specific usage and function of this embodiment are as follows:

[0032] After the user installs the first connecting seat 1 onto the second connecting seat 2, the first movable block 6 and the second movable block 7 will be connected together through the magnet 10. At this time, the user only needs to press the paddle 12 to drive one of the connecting rods 11, thereby rotating the first movable block 6 and the second movable block 7 to allow the first movable block 6 and the second movable block 7 to be cross-clamped in the two sets of fixing grooves 5, thereby fixing the first connecting seat 1 and the second connecting seat 2 together. Through this cross-clamping fixing method, the connection between the first connecting seat 1 and the second connecting seat 2 is strong. The degree of tension is effectively improved, which enables the coupling lock to effectively withstand external forces and vibrations from all directions. When it is necessary to release its fixed state, the user can push the paddle 12 to disengage the paddle 12 from the buckle 14. At this time, the spring 17 will release its squeezing force, thereby assisting the telescopic rod 15 to reset, to push the other set of connecting rods 11, thereby driving the first movable block 6 and the second movable block 7 to reset, thereby releasing its fixed state. Through this structure, the user can release its fixed state without manual operation, which effectively simplifies the operation process.

[0033] The basic principle and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
