Detailed Implementation

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The structural component of the present invention, which can be quickly connected and disassembled, mainly includes a mounting fastener 1, a mounting movable component 2, a connecting fastener 3, and a limiting component 4. The mounting fastener 1 is provided with a fixing threaded hole 11 that mates with the connecting fastener 3. The mounting movable component 2 is provided with a mounting through hole 21 and a connecting hole 22. The limiting component includes a fixed limiting component 41, a movable limiting component 42, and a bolt 43.

[0025] like Figure 1 As shown, the mounting connection part of the movable component 2 has a planar structure with multiple mounting through holes 21 and connecting holes 22, which are connected. The fixed connector 3 is pre-fixed into the fixed threaded hole 11 on the mounting fastener 1. It is typically a bolt, screw, or other connector. This type of part generally includes a limiting head 31 and a threaded neck 32. The diameter of the head 31 is larger than that of the neck 32, and the distance between the head 31 and the mounting surface 12 is slightly greater than the thickness of the movable component 2. The mounting through hole 21 allows passage through the head 31 of the connector, and the connecting hole 22 allows passage through the neck 32 of the connector but not through the head 31. The limiting component 4 includes a fixed limiting component 41 and a movable limiting component 42, which are fixedly mounted on the mounting fastener 1. The movable limiting component 42 is movably connected to the fixed limiting component 41 by bolts 43 and can move in the width direction. The opening size of the limiting component 4 in the width direction is the same as the width of the movable component 2, and both are V-shaped structures. The limiting component 4 is pre-fixed on the mounting fastener 1.

[0026] like Figure 2 , Figure 3As shown, during installation, first align the installation through hole 21 on the installation movable part 2 and pass through the head of the connecting fastener 3 until the installation surface two 23 of the installation movable part 2 contacts the installation surface one 12 of the installation fixed part 1, since the size of the installation through hole 21 is larger than the head 31 of the fixed connecting part, this process can be quickly achieved. Then drop the installation movable part 2, the circular installation through hole 21 can automatically position the neck 32 of the connecting part into the connecting hole 22, the V-shaped surface of the installation fixed part 1 and the installation movable part 2 are attached, and clamping is achieved under the action of gravity. Since the connecting fastener 3 is pre-installed on the installation fixed part 1, simply operating the connecting fastener 3 can fasten the installation movable part 2 on the installation fixed part 1, without the need to align the connecting fastener 3 with the fixed threaded hole 11 and then rotate and tighten it. At this time, the lower end of the installation movable part 2 enters the limiting part bottom clamping groove 44 and is limited, the movable limiting part 42 is moved inward and the bolt 43 is tightened, and the two sides of the installation movable part 2 are limited. The final installation and connection state is as shown in Figure 4 .

[0027] During disassembly, slightly loosen the bolt 43 and move the movable limiting part 42 outward, simply operate the connecting fastener 3 to lift the installation movable part 2, align the head 31 of the connecting fastener with the installation through hole 21, and take out the installation movable part 2 along the vertical installation surface one 12.

[0028] The limiting part 4 strengthens the limiting and restraining effect on the installation movable part 2.

[0029] The present application installs the connecting fastener in advance on the fixed device that needs to be installed and connected, a through hole and a connecting hole that do not have passing property are arranged on the installation movable part, the through hole and the connecting hole are communicated, the installation movable part can quickly pass through the connecting part and achieve fastening. The front surface of the installation movable part and the installation fixed part of the present application are both V-shaped structures, and positioning and clamping can be achieved by relying on the dead weight; the fixed device is provided with a limiting device matched with the installation movable part, which increases the connection reliability; the device and method can be used for quick disassembly of the installation movable part.
