[0002] The inflatable cabinet is a type of power distribution cabinet, which is a general term for the motor control center. The existing environmentally friendly inflatable cabinets with inlet and outlet lines have a relatively simple structure when inlet and outlet lines are used. A cable placement groove is directly opened on the surface of the environmentally friendly inflatable cabinet with inlet and outlet line structure, and the cable is extended to the outside of the environmentally friendly inflatable cabinet with inlet and outlet line structure through the cable placement groove. Since the inlet and outlet line structure is simple and concentrated in one through-hole inlet and outlet line, the sealing performance of the environmentally friendly inflatable cabinet with inlet and outlet line structure is reduced, and rainwater, foreign objects or animals can easily enter the interior of the environmentally friendly inflatable cabinet with inlet and outlet line structure through the inlet and outlet line through-hole, thereby damaging the internal components of the environmentally friendly inflatable cabinet with inlet and outlet line structure, affecting the normal power supply of the environmentally friendly inflatable cabinet with inlet and outlet line structure. Therefore, the applicant has made a beneficial design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

[0003] The purpose of the utility model is to overcome the shortcomings of the design of the environmentally friendly inflatable cabinet with the traditional inlet and outlet line structure, and to provide a product with good sealing performance and labor-saving installation.

[0012] Beneficial effects:

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The utility model applies downward pressure to the compression sleeve, and the conical part moves on the inclined surface, and gradually pushes the pushing block to squeeze the incoming line sleeve, so that it is deformed and closely attached to the surface of the wire, thereby preventing rainwater, foreign matter or animals from entering the inflatable cabinet through the gap between the wire and the incoming line sleeve, thereby ensuring the sealing of the inflatable cabinet. The elastic force released by the deformation of the incoming line sleeve causes the inclined surface to be pressed against the conical part, so that the compression sleeve is fixed in the position after the downward movement, so that it is firmly fixed.

[0015] (2) The utility model uses the elastic force released by the spring to give the push block, which not only acts as a pre-tightening force on the wire, but also reduces the force required to press the compression sleeve downward, making it easier to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It is worth mentioning that a sealing strip 21 is provided between the inlet board 2 and the cabinet 1, and the sealing strip 21 improves the sealing between the inlet board 2 and the cabinet 1, and prevents rainwater from entering the inflatable cabinet through the gap between the two;

[0029] It is worth mentioning that the inlet plate 2 is provided with a plurality of first through holes 22 for accommodating the inlet sleeve 3, a first blind hole 23 is provided at one end of the first through hole 22, a plurality of guide grooves 231 are evenly distributed on the inner wall of the first blind hole 23 with the dot as the axis, a countersunk hole 232 is also provided on the top of the first blind hole 23, the first through hole 22 is used in conjunction with the inlet sleeve 3, the guide groove 231 provides a guiding function for the push block 4, the first blind hole 23 provides an accommodating space for the action part 43, and the countersunk hole 232 provides a space for accommodating the first sealing ring 51;

[0030] It is worth mentioning that the push block 4 is slidably arranged in the guide groove 231, the push block 4 is provided with a second blind hole 41, the spring 42 is arranged in the second blind hole 41 and abuts against the end surface of the guide groove 231, the push block 4 is provided with an action portion 43 for fitting the shape of the incoming line sleeve 3, and is slidably arranged in the first blind hole 23, the push block 4 is provided with an increase block 44, the increase block 44 is provided with an inclined surface 45, the second blind hole 41 provides a storage space for the spring 42, and the elastic force released by the spring 42 is applied to the push block 4, so that the action portion 43 is pressed against the outer wall of the incoming line sleeve 3, providing a pre-tightening force for the wire in the incoming line sleeve 3, and also reducing the force required to press the compression sleeve 6 downward, so that it can be installed with less effort, and the inclined surface 45 is wide at the top and narrow at the bottom, and is used in conjunction with the tapered portion 61;

[0031] It is worth mentioning that the cover plate 5 is installed and fixed on the top of the first blind hole 23. The cover plate 5 is provided with a first sealing ring 51 and is arranged in the countersunk hole 232. The cover plate 5 is provided with a guide hole 52 for the compression sleeve 6 to move up and down. When the cover plate 5 is installed and fixed on the top of the first blind hole 23, it is tightly attached to the first sealing ring 51, thereby preventing rainwater from penetrating into the first blind hole 23. The guide hole 52 provides a guide for the compression sleeve 6.

[0032] It is worth mentioning that the compression sleeve 6 is provided with a tapered portion 61 and abuts against the inclined surface 45, and pressure-bearing surfaces 62 are provided on both sides of the compression sleeve 6. The pressure-bearing surfaces 62 are provided with second through holes 63, and the compression sleeve 6 is provided with a second sealing ring 64 and abuts against the guide hole 52. The diameter of the tapered portion 61 is narrow at the top and wide at the bottom. The pressure-bearing surface 62 facilitates the user to apply downward pressure to the compression sleeve 6.

The second sealing ring 64 prevents rainwater from entering the first blind hole 23 through the gap between the compression sleeve 6 and the guide hole 52.

[0033] It is worth mentioning that a pluggable plug 31 is provided at the entrance of the incoming sleeve 3. The material of the incoming sleeve 3 is set to rubber. When there is no wire passing through the incoming sleeve 3, in order to prevent rainwater, foreign objects or animals from entering the inflatable cabinet, the entrance of the incoming sleeve 3 is blocked by the plug 31. The incoming sleeve 3 made of rubber has a certain elasticity.

[0034] The use principle of the utility model is now described as follows:

[0035] Pull out the plug 31 and pass the wire through the incoming wire sleeve 3. When the wire is adjusted to enter the cabinet 1, the elastic force released by the spring 42 is applied to the outer wall of the incoming wire sleeve 3 through the action part 43, thereby applying a certain pre-tightening force to the wire, placing the compression sleeve 6 in the guide hole 52, and applying downward pressure through the pressure-bearing surface 62. The tapered portion 61 moves on the inclined surface 45 and gradually moves downward. The more the inclined surface 45 moves toward the upper part of the tapered portion 61, the more the action part 43 moves toward the axial direction of the incoming wire sleeve 3. The greater the force applied, the incoming wire sleeve 3 is squeezed and deformed, and fits more closely to the outer wall of the wire, preventing rainwater, foreign matter or animals from entering the inflatable cabinet through the gap between the wire and the incoming wire sleeve 3, thereby ensuring the sealing of the inflatable cabinet. The elastic force released by the deformation of the incoming wire sleeve 3 causes the inclined surface 45 to be pressed against the tapered portion 61, thereby fixing the compression sleeve 6 in the position after the downward movement, thereby completing the step of fixing the wire.

[0036] The above design scheme can enable the product to achieve the advantages of good sealing and labor-saving installation.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods.
