[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figure 1-6As shown, a quick-release connector includes a first connecting body 1, a second connecting body 2, and a fastening device 3. The fastening device 3 includes a fastening body 31, a fastening bolt 32, and a slider 33. The fastening bolt 32 and the slider 33 are threaded together. The fastening body 31 is fixedly mounted on the first connecting body 1. The second connecting body 2 includes a first connecting post 21 and a second connecting post 22. The first connecting post 21 is located at one end of the fastening body 31, and the second connecting post 22 is attached to the side of the slider 33 away from the first connecting post 21. By rotating the fastening bolt 33, the slider 33 moves up and down. During this up-and-down movement, the position of the slider 33 on the fastening body 31 changes. Since the first connecting post 21 is located at one end of the fastening body 31, and the second connecting post 22 is attached to the side of the slider 33 away from the first connecting post 21, changing the position of the slider 33 on the fastening body 31 allows for the clamping or disassembly of the first connecting post 21 and the second connecting post 22, thus enabling quick disassembly and installation of the first connecting body 1 and the second connecting body 2. The first connector 1 and the second connector 2 are connected, one to a mobile mechanical device and the other to a detachable tool, facilitating quick replacement of different tools. They can also be used for quick connections in other industries, such as train carriages.

[0027] The disassembly of the first connecting body 1 and the second connecting body 2 is achieved through the cooperation of the first connecting post 21 and the second connecting post 22 with the fastening body 31 and the slider 33. When the fastening body 31 and the slider 33 are positioned between the first connecting post 21 and the second connecting post 22, when the slider 33 moves away from the first connecting post 21 under the action of the fastening bolt 32, the slider 33 and the fastening body 31 clamp the first connecting post 21 and the second connecting post 22, and the second connecting body 2 and the first connecting body 1 are firmly connected into a whole. When the slider 22 moves towards the first connecting post 21 under the action of the fastening bolt 32, the slider 33 and the fastening body 31 release the first connecting post 21 and the second connecting post 22, thereby separating the second connecting body 2 from the first connecting body 1.

[0028] To better guide the slider 33 and prevent it from being unable to move along the fastener 31, the fastener 31 includes a guide groove 311. One end of the slider 33 is disposed within the guide groove 311, and the other end extends out of the guide groove 311. The second connecting post 22 is hooked onto the end of the slider 33 that extends out of the guide groove 311. The slider 33 can only move within the guide groove 311, preventing the clamping and disassembly of the second connecting body 2 and the first connecting body 1 from being impossible when rotating the fastening bolt 32.

[0029] The fastening device 3 further includes a half-tube 34, which is disposed between the second connecting post 22 and the second groove 313; the length of the half-tube 34 is greater than the width of the guide groove 311. The half-tube 34 is used to increase the contact area between the slider 33 and the second connecting post 22, increase stability, and avoid applying too much force to the second connecting post 22, which could cause the second connecting post 22 to deform.

[0030] The fastener 31 has a first groove 312 at its end connected to the first connecting post 21, and the first connecting post 21 is disposed within the first groove 312. The slider 33 has a second groove 313 at its end that mates with the second connecting post 22, and the second connecting post 22 is disposed within the second groove 313. The first groove 312 better secures the first connecting post 21, preventing it from detaching from the fastener 31 when the fastening bolt 32 is rotated, thus preventing the clamping and disassembly of the second connecting body 2 and the first connecting body 1 from being impossible. The second groove 313 better secures the second connecting post 22, preventing it from detaching from the slider 33 when the fastening bolt 32 is rotated, thus preventing the clamping and disassembly of the second connecting body 2 and the first connecting body 1 from being impossible.

[0031] During use, the fastening bolt 32 is easily rotated due to shaking or external force. This rotation causes the slider 33 to slide down under gravity, making it easy for the first connecting body 1 and the second connecting body 2 to separate, affecting practical use. The fastening body 31 has an arc surface 314 on one side of the guide groove 311. This arc surface 314 gradually moves away from the first connecting body 1 along the fastening body 31 from the second groove 313 towards the first groove 312. When the fastening bolt 32 slides, causing the slider 33 to move downwards under gravity, the arc surface 314 applies a force perpendicular to the fastening bolt 32 to the second connecting post 22, preventing the fastening bolt 32 from shaking due to external force and improving the reliability of the entire device. To better secure the fastening bolt 32, a fastening nut 321 is provided at the end of the fastening bolt.

[0032] The second connector 2 further includes a first guard plate 23, a second guard plate 24, and an end plate 25. The first guard plate 23 is connected to one end of the first connecting post 21 and the second connecting post 22, and the second guard plate 24 is connected to the other end of the first connecting post 21 and the second connecting post 22. The end plate 25 is connected to the first guard plate 23 and the second guard plate 24. The first guard plate 23 is disposed on one side of the fastener 31, and the second guard plate 24 is disposed on the other side of the fastener 31. The first guard plate 23 and the second guard plate 24 are disposed close to the fastener 31, which can both fix the first connecting post 21 and the second connecting post 22 and use the two sides of the fastener 31 to position the second connector 2, preventing the second connector 2 from sliding along the length direction of the first connecting post 21 and the second connecting post 22 during use, thus enhancing reliability. The end plate 25 is used to fix different tools or connected parts, appliances, etc.

[0033] The first connector 1 includes a mounting plate 11, a mounting plate 12, a mounting bolt 14, and an extension rod 17. The extension rod 17 is fixedly mounted on the mounting plate 12, and the mounting bolt 14 is disposed between the mounting plate 11 and the mounting plate 12. The extension rod 17 facilitates the connection of the first connector 1 to various operating levers and facilitates the fixation of the first connector 1. The mounting plate 11 is used to install the fastener 31, and the mounting plate 12 is used to install the extension rod 17.

[0034] The first connecting body 1 further includes a fixed cylinder 16 and an outer mounting plate 18. One end of the fixed cylinder 16 is fixedly mounted on the mounting plate 12, and one end of the extension rod 17 is fixedly inserted into the fixed cylinder 16. The outer mounting plate 18 is mounted on the fixed cylinder 16. The fixed insertion of one end of the extension rod 17 into the fixed cylinder 16 improves the installation accuracy of the extension rod 17. The outer mounting plate 18 is used to hang other engineering equipment.

[0035] The first connector 1 further includes a sleeve 13 and an inclined plate 15. The sleeve 13 is fixedly connected to the mounting plate 12, and the mounting bolt 14 passes through the sleeve 13. The inclined plate 15 is fixedly disposed between the sleeve 13 and the extension rod 17. The mounting plate 11 is provided with a connecting lug 111, and the mounting bolt 14 passes through the connecting lug 111 and the sleeve 13. The inclined plate 15 increases the structural strength of the sleeve 13 and the extension rod 17, preventing separation during use due to weak fixing methods such as welding. The connecting lug 111 facilitates the detachable connection or separation of the mounting plate 11 and the mounting plate 12 by the mounting bolt 14.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
