Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable sealing technology, and more specifically, to a cable sealing plug. Background Technology
[0002] Cable sealing plugs are used in outdoor or humid environments, such as substations, streetlights, and underground distribution rooms. They effectively prevent rainwater and groundwater from entering the equipment through cable perforations. For example, in outdoor distribution boxes in coastal areas, where humidity is high and rainfall is frequent, without cable sealing plugs, moisture can easily enter the distribution box along the cables, causing short circuits, damage to electrical equipment, and even safety accidents.
[0003] Among existing publicly available documents, patent publication number CN204258180U discloses a cable sealing structure for a blowout test plug. This technology uses a lead screw that passes through a driven gear and presses against a sealing gasket. One side of the lead screw has a groove, and an anti-rotation pin is installed in a pin hole on the side of the main body, with one end of the anti-rotation pin in the groove. The main body, the sealing gasket on the main body axis, and the center of the lead screw all have through-holes for wires. The DC motor assembly, wireless transceiver module, and battery inside the main body are all connected to the control module via wires. However, this patent has the following problems.
[0004] When using cable sealing plugs, the cable needs to be inserted into the sealing plug. However, when the plug is applied to the cable, only a single layer of extrusion pressure provides a binding seal, which is insufficient to achieve a spiral multi-point seal on the outside of the cable, resulting in a poor sealing effect. Utility Model Content
[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides the following technical solution: a cable sealing plug, comprising a sealing conical sleeve, wherein a sealing sleeve is fixedly connected to the inner wall of the sealing conical sleeve, and a spiral sealing assembly is provided on the outer wall of the sealing conical sleeve; the spiral sealing assembly includes a sealing pad fixedly disposed on the outer wall of the sealing conical sleeve, a connecting block is fixedly connected to the lower surface of the sealing pad, and a spiral binding rope is fixedly connected to one side of the connecting block, a pull block is fixedly installed at the bottom end of the spiral binding rope, and an adhesive strip is fixedly connected to one side of the pull block.
[0006] Preferably, the inner diameter of the top end of the sealing conical sleeve is smaller than the inner diameter of its bottom end, and the inner wall of the sealing conical sleeve is a smooth surface. The spiral binding rope is spiral-shaped and made of fiber material. An installation tube is installed on the upper surface of the sealing pad, and a cable is installed inside the installation tube. The cable is slidably connected to the sealing conical sleeve, and a through hole is provided on the inner wall of the installation tube.
[0007] The inner wall of the sealing conical sleeve is provided with a guide surface, and the inner wall of the guide surface is a smooth surface.
[0008] When using this technology, the cable is inserted into the guide surface inside the sealing conical sleeve. Along the inside of the sealing conical sleeve and the sealing sleeve, the pull block drives the spiral binding rope to move spirally. The connecting block supports the top of the spiral binding rope, and the spiral binding rope spirally squeezes and binds the outer wall of the sealing sleeve, thus adhering the adhesive strip to the outer wall of the cable.
[0009] Preferably, the outer wall of the sealing pad is provided with a double-layer sealing assembly; the sealing assembly includes a support block fixedly disposed on the outer wall of the sealing pad, an outer sleeve fixedly connected to the outer wall of the support block, a pressure ring embedded in the upper surface of the sealing pad, and an adhesive ring fixedly connected to the upper surface of the pressure ring. The upper surface of the outer sleeve is coated with a layer of adhesive, and the outer sleeve is adhesively bonded to the mounting tube.
[0010] When using this technology, the pressure ring squeezes the rubber ring, thus bonding and fixing the rubber ring to the installation tube. The sealing gasket supports the block, and the outer sleeve is bonded to the lower surface of the installation tube. The outer sleeve and the pressure ring can achieve a double seal at the bottom of the installation tube.
[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model inserts the cable into the guide surface inside the sealing conical sleeve, the sealing pad is pressed against the lower surface of the installation tube, the pull block drives the spiral binding rope to move spirally, the connecting block supports the top of the spiral binding rope, and the spiral binding rope spirally compresses and binds the outer wall of the sealing sleeve to seal, thus completing the multi-point spiral seal between the sealing sleeve and the cable, resulting in a better sealing effect. 2. This utility model uses a sealing gasket to compress the pressure ring. The rubber ring is pressed and bonded to the top of the inner wall of the installation tube, and the sealing gasket is pressed and bonded to the lower surface of the installation tube. The outer sleeve and the pressure ring can achieve a double seal on the bottom of the installation tube, resulting in a better sealing effect. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] As attached Figure 1 - Appendix Figure 4 The cable sealing plug shown is equipped with a spiral sealing assembly. The spiral sealing assembly enables the connecting block to support the top of the spiral binding rope. The spiral binding rope spirally compresses and binds the outer wall of the sealing sleeve to achieve a multi-point spiral seal between the sealing sleeve and the cable, resulting in a better sealing effect. The specific structural configuration of the spiral sealing assembly is as follows.
[0019] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, the device includes a sealing conical sleeve 1, with a sealing sleeve 2 fixedly connected to the inner wall of the sealing conical sleeve 1. A spiral sealing assembly is provided on the outer wall of the sealing conical sleeve 1. The spiral sealing assembly includes a sealing pad 3 fixedly disposed on the outer wall of the sealing conical sleeve 1. A connecting block 4 is fixedly connected to the lower surface of the sealing pad 3, and a spiral binding rope 5 is fixedly connected to one side of the connecting block 4. A pull block 6 is fixedly installed at the bottom end of the spiral binding rope 5, and an adhesive strip 7 is fixedly connected to one side of the pull block 6. The diameter of the inner wall at the top of the sealing conical sleeve 1 is smaller than the diameter of the inner wall at its bottom end, and the inner wall of the sealing conical sleeve 1 is a smooth surface. The spiral binding rope 5 is spiral-shaped and made of fiber material.
[0020] In this embodiment, as shown in the appendix Figure 1 - Appendix Figure 2 As shown, an installation tube 9 is mounted on the upper surface of the sealing gasket 3, and a cable 8 is installed inside the installation tube 9. The cable 8 is slidably connected to the sealing conical sleeve 1. A through hole 12 is provided on the inner wall of the installation tube 9 to allow the cable 8 to pass through the inside of the installation tube 9 for installation. A guide surface 10 is provided on the inner wall of the sealing conical sleeve 1, and the inner wall of the guide surface 10 is smooth to allow the cable 8 to be inserted into the guide surface 10 inside the sealing conical sleeve 1 for installation. The cable 8 is positioned by passing through the through hole 12.
[0021] When using this cable sealing plug, the cable 8 is inserted into the guide surface 10 inside the sealing conical sleeve 1, along the inside of the sealing conical sleeve 1 and the sealing sleeve 2. Then, the sealing pad 3 is pushed, and the sealing pad 3 is pressed against the lower surface of the mounting tube 9, thereby pulling the pull block 6. The pull block 6 drives the spiral binding rope 5 to move spirally. At the same time, the sealing pad 3 supports the connecting block 4, and the connecting block 4 supports the top of the spiral binding rope 5. The spiral binding rope 5 spirally compresses and binds the outer wall of the sealing sleeve 2, so that the sealing sleeve 2 can be spirally compressed and sealed. The adhesive strip 7 is then adhered to the outer wall of the cable 8, completing the multi-point spiral seal between the sealing sleeve 2 and the cable 8.
[0022] In this embodiment, as shown in the appendix Figure 4 As shown, the outer wall of the sealing pad 3 is provided with a double-layer sealing assembly; the sealing assembly includes a support block 11 fixedly disposed on the outer wall of the sealing pad 3, an outer sleeve 15 fixedly connected to the outer wall of the support block 11, a pressure ring 13 embedded in the upper surface of the sealing pad 3, and an adhesive ring 14 fixedly connected to the upper surface of the pressure ring 13. The upper surface of the outer sleeve 15 is coated with a layer of adhesive, and the outer sleeve 15 is glued to the mounting tube 9.
[0023] When using this cable sealing plug, the sealing gasket 3 is squeezed, which in turn squeezes the pressure ring 13, which in turn squeezes the rubber ring 14. The rubber ring 14 is then pressed and bonded to the top of the inner wall of the mounting tube 9, thus securing the rubber ring 14 to the mounting tube 9. Simultaneously, the sealing gasket 3 is pressed and bonded to the lower surface of the mounting tube 9. The sealing gasket 3 also supports the support block 11, which in turn supports the outer sleeve 15, which is bonded to the lower surface of the mounting tube 9. The outer sleeve 15 and the pressure ring 13 provide a double seal to the bottom of the mounting tube 9, resulting in a better sealing effect.
