The first fixing part 1 and the second fixing part 2 are docked and fixed to form an installation device, and the installation device is used to pre-embed the conducting part of the wiring and the sealing part with waterproof and dustproof.

In a further embodiment, as shown in FIG. 3 , the first fixing part 1 includes: a sleeve 101 , a first connecting part 103 and an annular connecting seat 105 . Moreover, the bottom of the sleeve 101 has a bent portion 102 extending outward with a predetermined width, and the fixed connection between the sleeve 101 and the housing is realized through the bent portion 102, and the connection can be welded or locked by screws. The first connecting piece 103 is fixed on the bending portion 102 and extends upward to a predetermined height. The first connecting piece 103 is used to connect to the annular connecting seat 105 and play a role of fixing the annular connecting seat 105 . Secondly, the arrangement of the first connecting piece 103 can also isolate the bending part 102 and the components inside the bending part 102 from the outside world, especially when bolts are used to fix it, it can play a dustproof and waterproof effect. At the same time, the sleeve 101 is a hollow structure, which is used for pre-embedding electric wires, and plays a very good role in protecting the electric wires especially when the environment is relatively harsh. And there is a predetermined gap between the inner wall of the first connecting piece 103 and the outer wall of the sleeve 101 to form a docking cavity 104; the setting of the docking cavity 104 is to realize the connection with the second fixing piece 2, and there will be further details below description of.

The ring 107 is fixedly connected. The connection method is glued or integrally formed. The connection between the lower sealing ring 109 and the upper sealing ring 107 constitutes a buffer, which can protect the connection between the bending portion 102 and the housing under any external force. Increase the cushioning performance between the housing and the first connecting piece 103, no matter in the process of installation or transfer, the upper sealing ring 107 and the lower sealing ring 109 can play a certain buffering role, avoiding damage to the housing due to external force. of damage.

In a further embodiment, as shown in FIG. 4 , the second fixing member 2 includes: an annular cover 201 installed on the support surface and fixed by welding, piling or screws. A connecting sleeve 202 is fixed on the bottom of the annular cover 201 , wherein the bottom of the connecting sleeve 202 is provided with a butt ring 203 extending downward. During installation, the docking ring 203 passes through the accommodating cavity 106 and the docking cavity 104 in sequence. At this time, the butt ring 203 and the sleeve 101 form a baffle channel, which has the effect of dustproof and waterproof.

In order to increase the sealing performance between the annular cover 201 and the annular connection seat 105, a certain distance is left between the outer wall of the docking ring 203 and the outer wall of the connecting sleeve 202 to form a reserved surface 204; In the recessed placement groove 205 , several rubber rings 206 are sequentially arranged in the placement groove 205 from top to bottom, and the rubber rings 206 are in contact with the annular connecting seat 105 and the docking ring 203 at the same time.

In the above structure, it is necessary to place the several rubber rings 206 in the accommodation cavity 106 first during installation, and then insert the docking ring 203, so that the rubber ring 206 will not affect it when the docking ring 203 is inserted ( Disordered placement makes it difficult to insert), so the bottom of the housing cavity 106 is provided with a gasket 207, the vertical section of the gasket 207 is L-shaped; . The gasket 207 not only plays the role of sealing the connection, but also plays the role of discharge management for the rubber ring 206 .
