Description

Technical Field

[0001] This invention belongs to the field of mechanical structure technology, specifically relating to a mechanism for the rapid installation and disassembly of loads. Background Technology

[0002] Traditional load mounting typically uses straight-end positioning, with the load direction determined and secured via bolt mounting holes. This method uses bolt tightening force to fix the load to locations such as the vehicle roof. However, this method suffers from drawbacks, including high precision requirements for straight-end machining, the need for tools for bolt tightening, and lengthy assembly / disassembly times. During vehicle use, situations frequently arise in field operations requiring load replacement. The aforementioned load mounting structure, requiring tools, makes it impossible to loosen the mounting bolts manually without them, thus hindering the performance of disassembly, maintenance, and repair tasks in such environments. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by this invention is: how to design a load-bearing installation mechanism that can quickly perform installation alignment, rely on manual installation for rapid installation, and has a large clamping force.

[0005] (II) Technical Solution

[0006] To solve the above technical problems, the present invention provides a quick installation and disassembly mechanism for a load, the quick installation and disassembly mechanism comprising: a load body 1, a mounting body 2, a ball positioning mechanism 4, and a quick fastening and disassembly mechanism 5;

[0007] The load body 1 serves as the mounting surface for the load, and a protruding straight cylinder is provided in the middle of its lower part for positioning. A ball positioning mechanism 4 is embedded in the outer wall of the straight cylinder.

[0008] The upper end of the mounting body 2 is provided with a straight cylindrical cavity that matches the straight cylinder, which is used to accommodate the straight cylinder. A vertical groove is provided on the inner wall of the straight cylindrical cavity, and a groove is provided at the bottom of the groove for accommodating the balls of the ball positioning mechanism 4.

[0009] The quick fastening and disassembly mechanism 5 is fixed to the mounting body 2 as a whole, and is used to apply a clamping force to the load body 1 to press it to the mounting body 2 so as to achieve fastening between the load body 1 and the mounting body 2; or to remove the clamping force so as to achieve quick disassembly of the load body 1.

[0010] The load body 1 has a horizontal blind hole on its straight cylindrical outer wall, and the ball positioning mechanism 4 is placed therein;

[0011] The ball positioning mechanism 4 includes a ball and a spring, with one end of the spring connected to the bottom of the blind hole and the other end in contact with the ball;

[0012] During the process of aligning the load body 1 and entering the mounting body 2, the ball positioning mechanism 4 moves from top to bottom along the groove vertically set in the mounting body 2 until it reaches the groove at the bottom of the groove. Under the action of spring force, the ball is stuck in the groove.

[0013] The ball positioning mechanism 4 enters along the groove vertically set in the mounting body 2 during the process of aligning the load body 1 and entering the mounting body 2, serving as a reference point for the orientation of the load installation. At the same time, it also serves as an auxiliary guide mechanism during the process of the straight cylinder of the load body 1 entering the mounting body 2. After installation, the ball positioning mechanism 4 serves as a positioning mechanism for the load body 1 and the mounting body 2, preventing the load body 1 from randomly rotating circumferentially or moving up and down relative to the mounting body 2 during use.

[0014] The transition section between the vertically arranged groove of the mounting body 2 and the groove at its end is provided with a certain slope, so that when an upward force is applied to the load body 1, the ball can return from the groove to the groove along the transition section with the slope, and then move upward with the load body 1.

[0015] When the load body 1 is installed on the mounting body 2, the sealing ring 3 is pressed on the mounting surface between the load body 1 and the mounting body 2 to achieve a seal between the load body 1 and the mounting body 2.

[0016] The quick fastening and disassembly mechanism 5 includes a mounting cavity 6, a clockwise threaded sleeve 7, a four-bar linkage 8, an upper hinge 9, a pressure plate 10, a counterclockwise threaded sleeve 11, a locking nut 12, and a bolt rod 13 with a wing nut.

[0017] The mounting cavity 6 is a hollow structure with an opening at the bottom, and a clamping plate 10 is matched and installed at the lower end; the outer wall of the mounting cavity 6 is fixedly connected to the mounting body 2.

[0018] The bolt rod 13 with a wing nut is horizontally inserted through the side wall of the mounting cavity 6, and the wing nut is located on the end of the bolt rod 13 located outside the mounting cavity 6; an upper hinge 9 is provided at the center of the inner wall of the top of the mounting cavity 6; correspondingly, a lower hinge is also provided at the center of the upper surface of the clamping plate 10.

[0019] On the rod portion of the bolt rod 13 that enters the mounting cavity 6, clockwise threaded sleeves 7 and counterclockwise threaded sleeves 11 are provided on the left and right sides; and the clockwise threaded sleeves 7 and counterclockwise threaded sleeves 11 are connected to the upper hinge 9 through two upper connecting rods. At the same time, the clockwise threaded sleeves 7 and counterclockwise threaded sleeves 11 are connected to the lower hinge through two lower connecting rods. The two upper connecting rods and the two lower connecting rods constitute a four-bar linkage 8.

[0020] On the bolt rod 13, a locking nut 12 is provided at one end of the counterclockwise threaded sleeve 11 near the wall of the mounting cavity 6.

[0021] The quick fastening and disassembly mechanism 5 applies a clamping force to the load body 1, pressing it tightly against the mounting body 2, to achieve the fastening between the load body 1 and the mounting body 2. Its working principle is as follows:

[0022] By manually rotating the bolt rod 13 with the wing nut clockwise, the relative movement of the screw sleeve 7 to the left and the screw sleeve 11 to the right drives the linkage of the four-bar linkage 8, thereby realizing the downward movement of the clamping plate 10, applying a clamping force towards the mounting body 2 to the load body 1, thus pressing the load body 1 onto the mounting body 2; after clamping in place, the locking nut 12 is fixed to achieve a firm connection between the load body 1 and the mounting body 2.

[0023] The working principle of the quick fastening and disassembly mechanism 5, which is used to release the clamping force to achieve quick disassembly of the load body 1, is as follows:

[0024] The process of disassembling the load body 1 is the reverse of the fastening process. First, manually loosen the fastening nut 12, and rotate the bolt rod 13 with the wing nut counterclockwise. Through the relative movement of the clockwise screw sleeve 7 to the right and the counterclockwise screw sleeve 11 to the left, the linkage of the four-bar linkage 8 is driven, thereby realizing the upward movement of the pressure plate 10 and releasing the load body 1.

[0025] The quick fastening and disassembly mechanism 5 is fixed to the mounting body 2.

[0026] The quick fastening and disassembly mechanism 5 is integrally formed with the mounting body 2.

[0027] (III) Beneficial Effects

[0028] Compared with existing technologies, this invention combines a straight-edge and ball-bearing positioning mechanism for positioning, enabling rapid mounting surface positioning of the load. The load's orientation is achieved via a spring hole, and the manual quick-installation mechanism allows for rapid manual installation and removal of the load device. Because the manual quick-installation mechanism employs a multi-link lever mechanism, a large clamping force can be achieved by manually driving the wing nut, replacing the method of connecting with bolts using tools such as wrenches. This results in rapid installation, convenient positioning, and simple disassembly, significantly improving the efficiency of load installation and removal. Attached Figure Description

[0047] The quick fastening and disassembly mechanism 5 applies a clamping force to the load body 1, pressing it tightly against the mounting body 2, to achieve the fastening between the load body 1 and the mounting body 2. Its working principle is as follows:

[0048] By manually rotating the bolt rod 13 with the wing nut clockwise, the relative movement of the screw sleeve 7 to the left and the screw sleeve 11 to the right drives the linkage of the four-bar linkage 8, thereby realizing the downward movement of the clamping plate 10, applying a clamping force towards the mounting body 2 to the load body 1, thus pressing the load body 1 onto the mounting body 2; after clamping in place, the locking nut 12 is fixed to achieve a firm connection between the load body 1 and the mounting body 2.
