[0033] For the purpose of making the technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.

[0034] The present application provides a quick docking and fixing device for the quick fixing of devices, which can be applied to the quick docking and fixing of devices.

[0035] As shown in Figure 1 and Figure 2 The quick docking and fixing device 10 provided by the present application includes a mounting seat 1, a limiting block 2, a handle 3, a torsional spring 4, a nut 5, a rotating shaft 6, a locking block 7, and a connecting piece 8.

[0036] The mounting seat 1 is horizontally arranged, and its left side surface is fixedly connected to the first device 20. A stepped hole is formed in the lower surface of the mounting seat 1, which includes a large hole 11 on the lower side and a small hole 12 on the upper side. The small hole 12 is in communication with the large hole 11. In some embodiments of the present application, the mounting seat 1 is of a rectangular structure, the large hole 11 is of a rectangular hole, and the small hole 12 is of a circular hole.

[0037] The connecting piece 8 is vertically arranged, and its lower end surface is fixedly connected to the second device 30. The upper end surface of the connecting piece 8 is provided with a vertical through groove 81, and a limiting groove 82 is arranged at the bottom of the through groove 81. The limiting groove 82 is in communication with the through groove 81, and the width of the limiting groove 82 is greater than that of the through groove 81, so that "c" shaped cavity bodies are formed on both sides of the limiting groove 82. In some embodiments of the present application, the connecting piece 8 is of a rectangular body structure, and its shape is adapted to the large hole 11 in the stepped hole. The upper end of the connecting piece 8 can be inserted into the large hole 11 of the mounting seat 1. The through groove 81 and the limiting groove 82 can both be rectangular grooves and are through in the front-rear direction.

[0038] The rotating shaft 6 is of a cylindrical stepped structure, which includes a small cylindrical structure with a smaller diameter on the upper side and a large cylindrical structure with a larger diameter on the lower side. The outer surface of the small cylindrical structure is provided with a thread, the small cylindrical structure partially protrudes out of the mounting seat 1 through the small hole 12 of the stepped hole in the mounting seat 1, the large cylindrical structure is located in the through groove 81 of the connecting piece 8 and is in contact with the end surface of the stepped hole of the mounting seat 1, and the rotating shaft 6 can rotate around the circular through hole of the mounting seat 1.

[0039] Locking block 7 is fixed at the end of the large cylinder of rotating shaft 6, which is located in the limiting slot 82 of connecting piece 8. Locking block 7 can pass through the through slot 81 so that the left and right ends of locking block 7 are located in the "c" shaped cavity of connecting piece 8, so that connecting piece 8 can be locked. In some embodiments of the present application, locking block 7 is rectangular structure, the short side of which is smaller than the width of the through slot 81, and the long side of which is larger than the width of the through slot 81, so that connecting piece 8 can be locked in the rectangular through hole of mounting seat 1 by rotating locking block 7.

[0040] Nut 5 is arranged on the upper side of mounting seat 1, which is screwed on the small cylindrical structure of rotating shaft 6 and is in contact with the upper surface of mounting seat 1.

[0041] Handle 3 is fixedly connected with the end of the small cylindrical structure of rotating shaft 6, which can be connected by welding or bolt, etc. In some embodiments of the present application, handle 3 can be long rectangular structure or round rod structure.

[0042] Torsional spring 4 is sleeved on the small cylindrical structure of rotating shaft 6 and is located between handle 3 and mounting seat 1. The upper end of torsional spring 4 is fixedly connected with handle 3, and the lower end of torsional spring 4 is fixedly connected with the upper surface of mounting seat 1, so as to provide a torque for rotating shaft 6 to rotate in a predetermined direction.

[0043] Limiting block 2 is fixedly arranged on the upper surface of mounting seat 1, and the distance between limiting block 2 and the axis of rotating shaft 6 is less than the transverse length of handle 3, so that when handle 3 is rotated to a certain angle, limiting block 2 can prevent rotating shaft 6 from continuing to rotate. In some embodiments of the present application, limiting block 2 can be long rectangular structure or round rod structure.

[0044] In use, rotate handle 3 counterclockwise to a certain angle, so that locking block 7 can pass through the through hole 81 of connecting piece 8. At this time, the upper end of connecting piece 8 is inserted into the large hole 11 of mounting seat 1, and then handle 3 is loosened. After handle 3 is rotated clockwise to a certain angle under the action of torsional spring 4, limiting block 2 blocks handle 3 from continuing to rotate, locking block 7 enters the limiting slot 82 of connecting piece 8 and cannot be pulled out, so that connecting piece 8 is locked in the large hole 11 of mounting seat 1, achieving the effect of quick docking and fixing.

[0045] When it is needed to unlock, rotate handle 3 to a certain angle, so that locking block 3 can leave the limiting slot 82 of connecting piece 8 and no longer limit the up and down movement of connecting piece 8, so as to realize the function of quickly unlocking connecting piece 8 from the large hole 11 of mounting seat 1.

[0046] The application utilizes the combined form of the limiting groove, through groove and locking block on the connecting piece, and through rotating the handle, the both ends of the locking block enter or leave the limiting groove of the connecting piece, so that the quick locking or unlocking effect of the connecting piece in the large hole 11 of the mounting seat is achieved; the combined form of the handle, torsional spring and limiting block is adopted, so that the rotating shaft always keeps the locking state under the action of the torsional spring, and the reliable locking ability in the external vibration environment is ensured, and the use efficiency and safety are improved.

[0047] The application fixes the equipment in a simple device, reduces the cost, has high reliability, realizes the quick docking and fixing between the equipment, and has simple, firm and convenient-to-use device which is not limited by external conditions.

[0048] The above is only a specific embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the application, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be subject to the protection scope of the claims.
