The clamping assembly overlaps the interior of the connecting sheet metal part and includes an upper part, a lower part, and an upper and lower plate connecting part.

[0005] By adopting the above technical solution, the upper and lower plate connectors connect the Z-shaped part, L-shaped part, upper part and lower part from top to bottom. The plug is placed inside the upper and lower plate connectors, clamping and fixing the irregular plug. The cooperation between the connecting sheet metal part and the clamping assembly makes the plug straight and horizontal to the ground, making it less prone to tilting. At the same time, the elastic pin can prevent the nut from loosening.

[0006] Preferably, the connecting sheet metal parts include Z-shaped parts and L-shaped parts. The top of the upper part overlaps the inner wall of the top of the Z-shaped part, and one side and the top of the Z-shaped part overlap the interior of the L-shaped part. The outer surfaces of the Z-shaped part and the L-shaped part are provided with a plurality of through holes.

[0007] By adopting the above technical solution, the through hole serves as an interface for connecting various components.

[0008] Preferably, the vertical plate of the Z-shaped component has a plug hole, and a positioning plate is fixedly connected to one side of the Z-shaped component. The positioning plate has a through hole that matches the plug.

[0009] By adopting the above technical solution, the second through hole is used to place the plug.

[0010] Preferably, both the upper and lower parts are provided with an arc-shaped hole and a through hole. The plug is snapped into the interior of the arc-shaped hole. The upper and lower plate connectors include a long bolt and a nut. The long bolt passes through the through hole of the Z-shaped part, the through hole of the L-shaped part, the through hole of the upper part, and the through hole of the lower part. The nut is threaded to the bottom of the long bolt, and one side of the nut is snapped into the bottom of the lower part.

[0011] By adopting the above technical solution, the plug is fixed as the nut is tightened, and the arc-shaped interface is adapted to various irregular plugs. It is even possible to use heating to melt the arc-shaped interface in contact with the irregular plug, so that the arc-shaped interface is more compatible with the irregular plug.

[0012] Preferably, both the upper and lower parts are provided with an arc-shaped hole and a through hole. The plug is snapped into the interior of the arc-shaped hole. The upper and lower plate connecting parts include elastic pins, which are snapped into the interior of the through hole one of the Z-shaped part, the through hole one of the L-shaped part, the through hole of the upper part, and the through hole of the lower part.

[0013] By adopting the above technical solution, the length of the elastic pin is equal to the distance from the top of the L-shaped part to the bottom of the lower part.

[0014] In summary, this utility model has the following beneficial technical effects: 1. This device is equipped with upper and lower plate connectors. By using long bolts and nuts, or elastic pins, the Z-shaped piece, L-shaped piece, upper piece and lower piece are connected from top to bottom. The plug is placed inside the arc-shaped hole. As the nut is tightened, the plug is locked by the upper and lower pieces, clamping and fixing the irregular plug. The through hole two and the arc-shaped hole match to make the plug straight and horizontal to the ground, so that it is not easy to tilt. At the same time, the elastic pin can prevent the nut from loosening. 2. This device is equipped with a clamping assembly made of plastic parts. Plastic parts are easy to manufacture and have low cost, allowing for quick modification of the plug fixing structure at a low cost. Through the cooperation of sheet metal parts and plastic parts, irregularly shaped plugs can be clamped and fixed. The plastic parts are located inside the Z-shaped parts, and part of the Z-shaped parts are located inside the L-shaped parts, thus fixing the plug and preventing the plug from tilting to the ground while saving space and without increasing modification costs.

[0019] Reference Figure 1 The device includes a plug 5, a connecting sheet metal part, and a clamping assembly. The plug 5 is an irregular cylinder with a sloping boss groove (not shown in the figure). The clamping assembly overlaps inside the connecting sheet metal part. The clamping assembly is made of plastic. Plastic parts are easy to manufacture and have low cost. The structure of the plug fixing part can be quickly modified at a low cost. Through the cooperation of the sheet metal part and the plastic part, the irregular plug 5 can be clamped and fixed and made to be horizontal to the ground. The clamping assembly includes an upper part 1, a lower part 2, and an upper and lower plate connecting part.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The connecting sheet metal parts include Z-shaped part 3 and L-shaped part 4. The top of the upper part 1 overlaps the inner wall of the top of the Z-shaped part 3. One side and the top of the Z-shaped part 3 overlap the interior of the L-shaped part 4. The Z-shaped part 3 and the L-shaped part 4 are connected to the scissor lift platform. The plastic part is located inside the Z-shaped part 3, and part of the Z-shaped part 3 is located inside the L-shaped part 4. This allows for the fixing of the plug 5 without increasing the modification cost and without saving space.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The outer surfaces of Z-shaped part 3 and L-shaped part 4 are provided with several through holes. Z-shaped part 3 and L-shaped part 4 are connected to the scissor lift platform through the through holes, bolts and other intermediate upper and lower plate connecting parts.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The vertical plate of the Z-shaped part 3 has a plug hole. A positioning plate is fixedly connected to one side of the Z-shaped part 3. The positioning plate is also made of sheet metal. The interior of the positioning plate has two through holes that are compatible with the plug.

[0023] Reference Figure 4 , Figure 5 , Figure 6Both the upper part 1 and the lower part 2 are provided with an arc-shaped hole 6 and a through hole 7. The plug 5 is snapped into the inside of the arc-shaped hole 6. The arc-shaped hole 6 and the through hole 7 cooperate, that is, the sheet metal part and the plastic part together fix the irregular plug 5, so that the plug 5 is secure and not easy to fall off and is horizontal to the ground.

[0024] Reference Figure 1 , Figure 3 The upper and lower plate connectors include a long bolt and a nut 8. The long bolt passes through the through hole 1 of the Z-shaped part 3, the through hole 1 of the L-shaped part 4, the through hole 7 of the upper part 1, and the through hole 7 of the lower part 2. The nut 8 is threaded to the bottom of the long bolt, and one side of the nut 8 is engaged with the bottom of the lower part 2. The Z-shaped part 3, the L-shaped part 4, the upper part 1, and the lower part 2 are connected from top to bottom. After the nut 8 is tightened, the long bolt is locked. After the nut 8 is loosened, the plug 5 can be pulled.

[0025] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 The upper and lower plate connecting parts include elastic pins 9, which are engaged inside the through hole 1 of Z-shaped part 3, the through hole 1 of L-shaped part 4, the through hole 7 of upper part 1 and the through hole 7 of lower part 2.

[0026] The implementation principle of the scissor lift platform plug fixing structure in this embodiment of the utility model is as follows: A long bolt passes through the through hole 1 of Z-shaped part 3, the through hole 1 of L-shaped part 4, the through hole 7 of upper part 1, and the through hole 7 of lower part 2, connecting Z-shaped part 3, L-shaped part 4, upper part 1, and lower part 2 from top to bottom, thereby placing the plug 5 inside the arc-shaped hole 6. As the nut 8 is tightened, the plug 5 is locked by upper part 1 and lower part 2. The through hole 2 and the arc-shaped hole 6 cooperate to make the plug 5 straight, so that the plug 5 is horizontal to the ground and is not easy to tilt. When concealing the overhead, a flexible pin 9 is used to replace the long bolt, connecting the Z-shaped part 3, L-shaped part 4, upper part 1, and lower part 2. A common tool can be used to insert the flexible pin 9 into the corresponding through hole 1 and the corresponding through hole 7. After the tool inserts the flexible pin 9 into the appropriate position, the tool is released, and the flexible pin 9 automatically unfolds, tightly supporting the corresponding through hole 1 and the corresponding through hole 7, thus locking the plug 5. When it needs to be removed, simply use a metal post that matches the through hole 1 and the through hole 7 to push out the flexible pin 9 to open it. At the same time, the through hole 2 and the arc-shaped hole 6 cooperate to make the plug 5 straight, so that the plug 5 is horizontal to the ground and not easy to tilt.

[0027] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
