Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet inlet sealing device. Background Art

[0002] The switch cabinet is an electrical equipment. The external wire of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. After the cable is inserted into the switch cabinet, a sealing device is needed to seal the wire entry hole to prevent water stains from entering the switch cabinet.

[0003] Authorization announcement number CN216929254U discloses a cable entry seal for a switch cabinet, wherein a first threaded rod is provided in the middle of the installation chamber, a nut is screwed onto the outer peripheral thread of the first threaded rod, connecting rods are fixed on both sides of the lower surface of the nut, the connecting rods penetrate the lower surface of the installation chamber, and a fixing block is fixed at the bottom end of the two connecting rods, a fixing ring is fixed at the bottom of the fixing block, and an arc-shaped limit plate is installed at the top end of the second threaded rod through a bearing. The added first threaded rod can drive the nut to move downward by rotating, and the fixing block will also drive the fixing ring to squeeze the wire from above as it moves downward, while the added second threaded rod can drive the arc-shaped limit plate to move upward by rotating, and the arc-shaped limit plate can squeeze the wire from below, so that the device can seal the gap between the wire and the inlet pipe, thereby improving the sealing performance of the device.

[0004] The disadvantage of the existing cable entry seal of the switch cabinet is that the first screw is required to push the fixing ring and the arc-shaped limit plate to close, clamp and fix the cable, and thus seal the switch cabinet entry hole, but the fixing ring and the arc-shaped limit plate are not arc-shaped, and cannot effectively seal the entry hole. To this end, we propose a switch cabinet entry sealing device. Utility Model Content

[0005] The main purpose of the utility model is to provide a switch cabinet incoming line sealing device, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A switch cabinet inlet sealing device comprises a first limiting ring, a sealing sleeve is welded on one side of the first limiting ring, a rubber sleeve is sleeved on the inner side of the sealing sleeve, a second limiting ring is arranged on one side of the sealing sleeve, a pusher is welded on the side of the second limiting ring close to the sealing sleeve, and limiting components are arranged on the inner sides of the first limiting ring and the second limiting ring;

[0008] The limiting assembly comprises limiting grooves which are equidistantly arranged on the inner sides of the first limiting ring and the second limiting ring, a round head column is sleeved inside the limiting groove, and a compression spring is arranged inside the limiting groove.

[0009] Furthermore, a thread groove is provided on the inner surface of the sealing sleeve, and thread teeth are provided on the outer surface of the pushing cylinder.

[0010] Furthermore, slots are equidistantly formed on the outer sides of the first limiting ring and the second limiting ring.

[0011] Furthermore, one end of the round head column located inside the limiting groove is fixed to the limiting block by a bolt.

[0012] Furthermore, the rubber sleeve is made of nitrile rubber material.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Insert the sealing sleeve into the wire inlet hole of the switch cabinet from the outside of the switch cabinet, and make the first limiting ring close to the outside of the switch cabinet, screw the push barrel into the second limiting ring through the thread teeth and the thread groove, and make the second limiting ring close to the inside of the switch cabinet. When the push barrel enters the second limiting ring, the rubber sleeve is squeezed so that the rubber sleeve is fully filled between the cable and the sealing sleeve, thereby sealing the sealing sleeve and the cable.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a switch cabinet incoming line sealing device comprises a first limiting ring 1, a sealing sleeve 3 is welded on one side of the first limiting ring 1, a rubber sleeve 6 is sleeved on the inner side of the sealing sleeve 3, a second limiting ring 2 is arranged on one side of the sealing sleeve 3, a pusher 4 is welded on the side of the second limiting ring 2 close to the sealing sleeve 3, and limiting components 5 are arranged on the inner sides of the first limiting ring 1 and the second limiting ring 2;

[0022] The limiting assembly 5 includes limiting grooves 501 equidistantly arranged inside the first limiting ring 1 and the second limiting ring 2 , a round head column 502 is sleeved inside the limiting groove 501 , and a compression spring 504 is arranged inside the limiting groove 501 .

[0023] Among them, Figure 2 and Figure 3 As shown, the inner surface of the sealing sleeve 3 is provided with a thread groove 7, and the outer surface of the pushing barrel 4 is provided with thread teeth 8. The arrangement of the thread groove 7 and the thread teeth 8 facilitates the pushing barrel 4 to be screwed into the second limiting ring 2.
