Description

Technical Field

[0001] This utility model relates to the field of explosion-proof distribution cabinet technology, specifically to an adjustable explosion-proof distribution cabinet inlet and outlet sealing structure. Background Technology

[0002] Distribution cabinet is a general term for motor control center. Distribution cabinets are suitable for occasions where the load is relatively dispersed and there are few circuits. When using distribution cabinets, slots need to be opened in them so that cables can be smoothly entered and exited.

[0003] Since the inlet and outlet dimensions of the distribution cabinet are fixed, there is a certain gap between the cable and the distribution cabinet. In order to prevent rainwater, dust and foreign objects from entering the distribution cabinet and damaging the internal components, thus affecting the service life of the equipment, most existing technologies use fireproof putty to seal the gap between the cable and the distribution cabinet. However, the fireproof putty will melt during long-term use, affecting the sealing effect of the cable. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable explosion-proof distribution cabinet inlet and outlet sealing structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An adjustable explosion-proof distribution cabinet inlet and outlet sealing structure includes a connecting sealing mechanism, and a fixing mechanism is provided at the bottom of the connecting sealing mechanism;

[0007] The connecting sealing mechanism includes a gland tube, a rotating sleeve rotatably connected to the outer surface of the bottom end of the gland tube, a fixed ring fixedly connected to the inside of the bottom end of the gland tube, and a rotating ring fixedly connected to the inside of the bottom end of the rotating sleeve. The top surface of the fixed ring has a circumferential array of guide grooves, and the top surface of the rotating ring has a circumferential array of arc-shaped grooves. A fixed post is slidably arranged inside the guide groove, and a rotating post is slidably arranged inside the arc-shaped groove. One end of the fixed post is fixedly connected to a sealing block, and the rotating post is rotatably connected inside the sealing block.

[0008] A further improvement of this utility model is that: a hexagonal nut one is fixedly connected to the outer surface of the gland tube, the outer surface of the gland tube is threaded, a hexagonal nut two and a threaded ring are threadedly connected to the outer surface of the gland tube, the hexagonal nut two and the threaded ring are located below the hexagonal nut one, and through holes are arranged in a circumferential array on the top surface of the hexagonal nut two.

[0009] A further improvement of this utility model is that: a fixing rod is fixedly connected to the top surface of the rotating sleeve in a circumferential array, and the fixing rod is slidably disposed inside the through hole.

[0010] A further improvement of this utility model is that: the outer surface of the gland tube is threaded with a hexagonal nut three, and the hexagonal nut three is located above the hexagonal nut one.

[0011] A further improvement of the present invention is that the fixing mechanism includes a guide tube, the guide tube is fixedly connected to the bottom surface of the rotating sleeve, a guide ring is fixedly connected inside the bottom end of the guide tube, the outer surface of the guide tube is threaded, a threaded tube is threadedly connected to the outer surface of the guide tube, and a stepped ring is fixedly connected inside the bottom end of the threaded tube.

[0012] A further improvement of this utility model is that a collar is slidably connected to the top of the stepped ring, and the collar and the stepped ring are interference fit.

[0013] A further improvement of this utility model is that a conical plate is fixedly connected to the top surface of the collar in a circumferential array, and the top end of the conical plate is rounded.

By rotating the hexagonal nut, the fixed rod, the rotating sleeve and the rotating ring are driven to rotate. When the rotating ring rotates, it drives multiple sealing blocks to rotate synchronously through the arc groove and the rotating column. The fixed ring restricts the movement direction of the sealing blocks through the guide groove and the fixed column. Multiple sealing blocks move synchronously and fit against the outer surface of the cable, thereby achieving clamping and sealing of cables of different thicknesses.

[0016] 2. This utility model provides an adjustable explosion-proof distribution cabinet inlet and outlet sealing structure.

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] Example 1

[0027] like Figure 1-5 As shown, this utility model provides an adjustable explosion-proof distribution cabinet inlet and outlet sealing structure, including a connecting sealing mechanism 1. A fixing mechanism 2 is provided at the bottom of the connecting sealing mechanism 1. The connecting sealing mechanism 1 includes a gland tube 101. A rotating sleeve 102 is rotatably connected to the outer surface of the bottom end of the gland tube 101. A fixing ring 103 is fixedly connected inside the bottom end of the gland tube 101. A rotating ring 104 is fixedly connected inside the bottom end of the rotating sleeve 102. A guide groove 105 is circumferentially arranged on the top surface of the fixing ring 103. An arc-shaped groove 106 is circumferentially arranged on the top surface of the rotating ring 104. A fixing post is slidably arranged inside the guide groove 105. A rotating post is slidably arranged inside the arc-shaped groove 106. One end of the fixing post is fixed... A fixed connecting sealing block 107 is provided, and a rotating column is rotatably connected inside the sealing block 107. A hexagonal nut 108 is fixedly connected to the outer surface of the gland tube 101. The outer surface of the gland tube 101 is threaded. A hexagonal nut 109 and a threaded ring 110 are threadedly connected to the outer surface of the gland tube 101. The hexagonal nut 109 and the threaded ring 110 are located below the hexagonal nut 108. A through hole is formed in the circumferential array on the top surface of the hexagonal nut 109. A fixing rod 111 is fixedly connected to the circumferential array on the top surface of the rotating sleeve 102. The fixing rod 111 is slidably disposed inside the through hole. A hexagonal nut 112 is threadedly connected to the outer surface of the gland tube 101. The hexagonal nut 112 is located above the hexagonal nut 108.

[0028] In this embodiment, when using the inlet / outlet sealing device, the cable is passed through the fixing mechanism 2 and the gland tube 101 with a suitable length reserved. The fixing mechanism 2 clamps and fixes the cable. Rotating the hexagonal nut 109 causes it to rotate along the outer surface of the gland tube 101, which in turn drives the rotating sleeve 102 and the rotating ring 104 to rotate via the fixing rod 111. When the rotating ring 104 rotates, it drives multiple sealing blocks 107 to rotate synchronously via the arc groove 106 and the rotating column. The fixing ring 103, through the guide groove 105 and the fixing column, can improve the movement stability of the sealing blocks 107 and restrict the movement direction of the sealing blocks 107. Multiple sealing blocks 107 move synchronously and fit against the outer surface of the cable, thereby sealing the cable. The sealing blocks 107 are made of rubber. When the sealing blocks 107 fit against the outer surface of the cable, the sealing blocks 107 deform. This fills the gap between the sealing block 107 and the cable, improving the sealing effect of the sealing block 107 on the cable. After multiple sealing blocks 107 seal the cable, the rotation of the hexagonal nut 109 is stopped and the threaded ring 110 is rotated. The hexagonal nut 109 restricts the rotation of the rotating sleeve 102 and the rotating ring 104 through the fixing rod 111, thereby restricting the movement of the sealing block 107. The threaded ring 110 rotates along the outer surface of the gland tube 101 and fits against the hexagonal nut 109. The threaded ring 110 restricts the rotation of the hexagonal nut 109, thereby restricting the rotation of the fixing rod 111, the rotating sleeve 102 and the rotating ring 104. This prevents the hexagonal nut 109 from loosening during use and causing the rotating sleeve 102 and the rotating ring 104 to rotate through the fixing rod 111, which would affect the sealing effect of the sealing block 107 on the cable.

[0029] After the cable is sealed, insert the gland tube 101 into the inlet hole at the bottom of the explosion-proof distribution cabinet, and connect the hexagonal nut 312 to the gland tube 101. The hexagonal nut 312 rotates along the outer surface of the gland tube 101 and clamps the explosion-proof distribution cabinet with the hexagonal nut 108, thereby fixing the gland tube 101 on the explosion-proof distribution cabinet.

[0030] Example 2

[0031] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the fixing mechanism 2 includes a guide tube 201, which is fixedly connected to the bottom surface of the rotating sleeve 102. A guide ring 202 is fixedly connected inside the bottom end of the guide tube 201. The outer surface of the guide tube 201 is threaded, and a threaded tube 203 is threadedly connected to the outer surface of the guide tube 201. A stepped ring 204 is fixedly connected inside the bottom end of the threaded tube 203. A collar 205 is slidably connected to the top end of the stepped ring 204. The collar 205 and the stepped ring 204 are interference fit. A conical plate 206 is fixedly connected to the top surface of the collar 205 in a circumferential array. The top end of the conical plate 206 is rounded.

[0032] In this embodiment, before using the inlet and outlet sealing device, the threaded tube 203 is rotated, and the threaded tube 203 rotates along the outer surface of the guide tube 201 and separates from the guide tube 201, connecting the collar 205 and the stepped ring 204. The stepped ring 204 and the collar 205 are interference fit, thereby restricting the movement of the collar 205. Both the collar 205 and the conical plate 206 are made of plastic and can deform themselves.

[0033] When using the inlet and outlet sealing device, the cable is passed through the threaded tube 203, guide tube 201 and gland tube 101 with an appropriate length reserved. The threaded tube 203 is connected to the guide tube 201. The threaded tube 203 rotates along the outer surface of the guide tube 201 and drives the collar 205 and the conical plate 206 to move through the stepped ring 204. The conical plate 206 enters the guide ring 202 and the guide tube 201 and contacts the inner ring surface of the guide ring 202. As the threaded tube 203 continues to rotate, multiple conical plates 206 clamp and fix the cable due to the deformation of the guide ring 202. The top of the conical plate 206 is rounded to avoid damage to the cable.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
