[0001] This utility model relates to the field of cable conduit connection technology, and more specifically, to a cable protection conduit connection structure that improves sealing performance. Background Technology

[0002] As an important protective component of power and communication systems, the sealing performance of cable protection pipes directly affects the pipeline's resistance to water seepage, corrosion, and long-term reliability.

[0003] A search revealed that Chinese Patent Publication No. CN221574802U discloses "a high-seal cable conduit connector, comprising a connecting seat, a clamping block, and a pipe body. The clamping block is located at the bottom of the connecting seat, and the pipe body is sleeved between the inner cavity of the connecting seat and the inner sidewall of the clamping block. A nut is screwed onto the lower side of the outer sidewall of the connecting seat. A sealing washer is fixedly connected around the bottom of the connecting seat and within the inner cavity of the nut. A connecting ring is fixedly connected around the top outer side of the connecting seat. A sealing ring is placed in the inner cavity of the connecting ring, and a toothed ring is fixedly connected around the inner sidewall of the sealing ring, with the toothed rings arranged sequentially from top to bottom. This high-seal cable conduit connector has a reasonable structural design, which can improve the sealing performance of the cable conduit connector without affecting the connection stability. It can also be used for the installation and docking of various cable conduits, improving the versatility of the cable conduit connector." However, it still has the following drawbacks: (1) This device requires manual screwing of the nut to tighten the sealing gasket, and lacks a quick locking structure. Therefore, the installation efficiency is low in batch construction.

[0004] (2) It cannot adaptively adjust to different diameters or materials of cable pipes, and the clamping blocks need to be replaced, which is cumbersome and inconvenient to use.

[0005] Therefore, we have made improvements and proposed a cable protection pipe connection structure with improved sealing performance. Utility Model Content

[0006] The purpose of this utility model is to address the problems of the current lack of a quick locking structure, low installation efficiency in batch construction, inability to adaptively adjust to cable pipes of different diameters or materials, the need to replace clamping blocks, cumbersome operation, and inconvenience in use.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: Improve the sealing performance of cable protection conduit connection structures to address the aforementioned issues.

[0008] The specific details of this utility model are as follows: It includes a first retaining ring, a second retaining ring sleeved on the outer side of the first retaining ring, a quick-locking component for quickly locking the first retaining ring and the second retaining ring, and a buffer sealing component for providing cushioning for the quick-locking component inside the second retaining ring; The quick-locking assembly includes two sets of safety cams hinged to the outer side of the second retaining ring. The two sets of safety cams are symmetrically distributed along the periphery of the second retaining ring, penetrate the second retaining ring, and extend into the interior of the second retaining ring. The outer wall of the first retaining ring has an annular groove, and one end of the first retaining ring has two sets of rectangular grooves. The two sets of rectangular grooves are symmetrically distributed along the periphery of the second retaining ring.

[0009] As a preferred technical solution of this utility model, the buffer sealing assembly includes a buffer pad located inside the second retaining ring. The buffer pad is located on one side of the first retaining ring, and a toothed groove is formed inside the second retaining ring. The buffer pad is located inside the toothed groove.

[0010] As a preferred technical solution of this utility model, two sets of positioning blocks are fixedly provided on the outer wall of the first retaining ring, and the positions of the two sets of positioning blocks correspond to the positions of the two sets of rectangular grooves.

[0011] As a preferred embodiment of this utility model, a first protective tube is sleeved inside the first retaining ring, and a second protective tube is sleeved inside the second retaining ring.

[0012] As a preferred technical solution of this utility model, multiple sets of anti-slip rings are fixedly provided on the inner wall of the first retaining ring, and the anti-slip rings are also located on the inner wall of the second retaining ring.

[0013] As a preferred technical solution of this utility model, a sealing ring is fixedly connected to one end of the first retaining ring and the second retaining ring, and the sealing ring is made of silicone.

[0014] As a preferred technical solution of this utility model, the ends of both sets of safety cams are rotatably connected to pull rings, and the surface of the pull rings is coated with a fluorescent coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. With the designed quick-locking assembly, during use, the second retaining ring is fitted onto the first retaining ring. The two sets of safety cams slide along the rectangular groove of the first retaining ring until they are embedded in the annular groove. At this point, the bottom of the safety cam fits tightly against the annular groove. Then, the first retaining ring is rotated 90 degrees, and the safety cam is rotated above the second retaining ring. During this process, the safety cam is squeezed from above the second retaining ring and contracts towards the second retaining ring. This contraction action causes the safety cam to exert additional pressure on the contact surface between the second and first retaining rings, further tightening the contact surface between the first and second retaining rings, thereby achieving a quick and secure locking connection. This effectively prevents loosening, improves sealing, and is simple and convenient to operate.

[0016] 2. With the buffer sealing assembly in place, when the safety cam is rotated to lock the first and second retaining rings together, one end of the first retaining ring will fit against the surface of the buffer pad. The buffer pad, due to its elastic properties, will deform elastically when squeezed by the end of the first retaining ring, thereby absorbing the impact energy generated during the movement of the first retaining ring. This prevents one end of the first retaining ring from directly colliding with the inner wall of the second retaining ring, thus reducing wear caused by collision and friction and extending the service life of the first and second retaining rings.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0020] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] like Figure 1 and Figure 3 As shown, this embodiment proposes a cable protection pipe connection structure to improve sealing performance, including a first retaining ring 1, a second retaining ring 2 sleeved on the outside of the first retaining ring 1, a quick-locking component 3 for quickly locking the first retaining ring 1 and the second retaining ring 2, and a buffer sealing component 4 for providing buffer for the quick-locking component 3 inside the second retaining ring 2. like Figure 2As shown, the quick-locking assembly 3 includes two sets of safety cams 301 hinged to the outer side of the second retaining ring 2. The two sets of safety cams 301 are symmetrically distributed along the periphery of the second retaining ring 2, and penetrate through the second retaining ring 2 and extend into the interior of the second retaining ring 2. The outer wall of the first retaining ring 1 is provided with an annular groove 302, which is used to accommodate the bottom of the safety cam 301 so that it fits tightly. One end of the first retaining ring 1 is provided with two sets of rectangular grooves 303, which provide precise guidance and constraint for the positioning and movement of the two sets of safety cams 301, ensuring that the safety cams 301 can be accurately embedded and realize the locking function. The two sets of rectangular grooves 303 are symmetrically distributed along the periphery of the second retaining ring 2. In use, the second retaining ring 2 is fitted onto the first retaining ring 1. The two sets of safety cams 301 slide along the rectangular groove 303 of the first retaining ring 1 until they are embedded in the annular groove 302. At this time, the bottom of the safety cam 301 is tightly fitted with the annular groove 302. Then, the first retaining ring 1 is rotated 90 degrees, and the safety cam 301 is rotated above the second retaining ring 2. During this process, the safety cam 301 is squeezed from above the second retaining ring 2 and contracts towards the second retaining ring 2. This contraction action causes the safety cam 301 to generate additional pressure on the contact surface between the second retaining ring 2 and the first retaining ring 1, further pressing the contact surface between the first retaining ring 1 and the second retaining ring 2, thereby achieving a quick and firm locking connection. This effectively prevents loosening, improves sealing, and is simple and convenient to operate.

[0024] like Figure 4 As shown, the buffer sealing assembly 4 includes a buffer pad 401 located inside the second retaining ring 2. The buffer pad 401 is located on one side of the first retaining ring 1. The second retaining ring 2 has a toothed groove 402 inside, and the buffer pad 401 is located in the toothed groove 402. In use, when the safety cam 301 is rotated to lock the first retaining ring 1 and the second retaining ring 2 together, one end of the first retaining ring 1 will adhere to the surface of the buffer pad 401. Due to its elastic properties, the buffer pad 401 undergoes elastic deformation when squeezed by the end of the first retaining ring 1, thereby absorbing the impact energy generated during the movement of the first retaining ring 1. This prevents one end of the first retaining ring 1 from directly colliding with the inner wall of the second retaining ring 2, thereby reducing wear caused by collision and friction and extending the service life of the first retaining ring 1 and the second retaining ring 2.

[0025] like Figure 2 As shown, two sets of positioning blocks 5 are fixedly installed on the outer wall of the first retaining ring 1, and the positions of the two sets of positioning blocks 5 correspond to the positions of the two sets of rectangular grooves 303. The corresponding arrangement of the rectangular blocks and the rectangular grooves 303 provides precise positioning for the connection of the first retaining ring 1 and the second retaining ring 2, reduces deviations during the installation process, and enables installers to connect the first retaining ring 1 and the second retaining ring 2 more quickly and accurately, simplifying the installation process and improving installation efficiency.

[0026] like Figure 1 As shown, a first protective tube 6 is sleeved inside the first retaining ring 1, and a second protective tube 7 is sleeved inside the second retaining ring 2. The first protective tube 6 is sleeved inside the first retaining ring 1, and the second protective tube 7 is sleeved inside the second retaining ring 2. When the first retaining ring 1 and the second retaining ring 2 are locked together by operations such as rotating the safety cam 301, the connection between the first protective tube 6 and the second protective tube 7 is realized.

[0027] like Figure 3 As shown, multiple sets of anti-slip rings 8 are fixedly arranged on the inner wall of the first retaining ring 1. The anti-slip rings 8 are also located on the inner wall of the second retaining ring 2. By setting multiple sets of anti-slip rings 8, the surface roughness of the inner walls of the first retaining ring 1 and the second retaining ring 2 is increased, which can prevent the first protective tube 6 from sliding out of the first retaining ring 1.

[0028] like Figure 3 As shown, a sealing ring 9 is fixedly connected to one end of the first retaining ring 1 and the second retaining ring 2 respectively. The sealing ring 9 is made of silicone. The silicone ring fits tightly against the surface of the first protective tube 6, which can prevent external dust and impurities from entering the interior of the first retaining ring 1 and extend the service life of the first retaining ring 1.

[0029] like Figure 3 As shown, the ends of both sets of safety cams 301 are rotatably connected to pull rings 10. The surface of the pull rings 10 is coated with a fluorescent coating, which allows the safety cams 301 to be rotated more conveniently and quickly through the pull rings 10, and can be quickly positioned in dark environments.

[0030] Specifically, this cable protection conduit connection structure with improved sealing is used as follows: Figure 1 As shown, the first protective tube 6 is fitted inside the first retaining ring 1, the second protective tube 7 is fitted inside the second retaining ring 2, and the second retaining ring 2 is fitted onto the first retaining ring 1, as shown. Figure 2 As shown, the two sets of safety cams 301 slide along the rectangular groove 303 of the first retaining ring 1 until they are embedded in the annular groove 302. At this time, the bottom of the safety cam 301 is tightly fitted with the annular groove 302. Then, the first retaining ring 1 is rotated ninety degrees, and the safety cam 301 is rotated above the second retaining ring 2. During this process, the safety cam 301 is squeezed from above the second retaining ring 2 and contracts towards the second retaining ring 2. This contraction action causes the safety cam 301 to generate additional pressure on the contact surface between the second retaining ring 2 and the first retaining ring 1, further pressing the contact surface between the first retaining ring 1 and the second retaining ring 2, thereby achieving a fast and firm locking connection. This effectively prevents loosening, improves sealing, and is simple to operate and convenient to use.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
