Description

Technical Field

[0001] This utility model relates to the field of civil defense conduits, and in particular to a civil defense conduit structure for laying multiple cables. Background Technology

[0002] Civil defense conduit sleeves are pipe protection devices used in civil air defense projects. Their main function is to install conduits passing through exterior walls or walls exposed to air raids in areas such as basements where they may be damaged by air raids. During an air raid, a powerful shock wave is generated. If cables pass directly through the civil defense wall without the shock wave, they can easily be damaged. Placing the cables inside the civil defense conduit sleeve allows the sleeve to withstand and disperse the energy of the shock wave, protecting the cables.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: Existing civil defense conduits for laying multiple cables generally include a conduit body, cables, waterproof coating, and other structures. When the existing conduit body is subjected to pressure, it mostly relies on the strength of its own material for support. This support and protection mechanism is relatively simple and its effect is unsatisfactory. At the same time, most of the existing multiple cables enter the conduit together. When one cable short-circuits, the heat generated may be transferred to the other cables, causing the other cables to burn out. In addition, the existing conduit head lacks a mechanism to protect the cables when the cables are split, which makes the cables prone to wear and breakage when bent.

[0004] Therefore, those skilled in the art have provided a civil defense conduit structure for laying multiple cables to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a civil defense conduit structure for laying multiple cables. The support mechanism can significantly improve the protection level of the cables, while the snap-fit ​​mechanism can protect the cable bends and facilitate diversion and replacement of the second conduit.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a civil defense sleeve structure for laying multiple cables, including a support mechanism and a snap-fit ​​mechanism. The support mechanism includes a support tube and a first tube. A fixing sleeve is fixedly connected to the outer wall of the first tube. Two first springs are fixedly connected to the outer walls of multiple fixing sleeves. A support block is fixedly connected to multiple first springs away from the first tube.

[0007] The locking mechanism includes a locking post, a second tube, and multiple third tubes. The bottom of the locking post is movably disposed inside the top of the second tube. A pull block is fixedly connected to the top of the locking post, and a second spring is fixedly connected to the bottom of the pull block away from the locking post.

[0008] Furthermore, the top of the support tube is fixedly connected to the bottom of the two second springs near the second tube.

[0009] Furthermore, the locking post penetrates the top of the support tube near the second tube, and the locking post is slidably connected to the inner wall of the top of the support tube near the second tube.

[0010] Furthermore, four branch pipes are fixedly installed on the inner wall of the second pipe, and the four branch pipes are spaced 90 degrees apart.

[0011] Furthermore, the outer wall of the second tube near the support tube is slidably connected to the inner wall of the support tube, and the inner wall of the support tube is slidably connected to the side of the multiple support blocks away from the first tube.

[0012] Furthermore, each of the three tubes is fixedly connected to a fixing plate on the side away from the first tube, and the end of the fixing plate away from the three tubes is fixedly connected to the inner wall of the first tube.

[0013] Furthermore, each of the multiple No. 1 springs is internally connected to a telescopic rod, the ends of the multiple telescopic rods away from the No. 1 tube are fixedly connected to the multiple support blocks, and the ends of the multiple telescopic rods away from the multiple support tubes are fixedly connected to the multiple fixed sleeves. The outer wall of each support tube is fixedly provided with a waterproof coating.

[0014] This utility model has the following beneficial effects:

[0015] 1. The present invention proposes a civil defense conduit structure for laying multiple cables. When the wall is bombed and the internal structure is damaged or the wall shakes and squeezes the internal support pipe, the support pipe collapses after being squeezed and transmits the pressure to the support block. The pressure is then transmitted through the support block to the No. 1 spring and the telescopic rod until the edges of the four support blocks contact each other, forming a ring outside the No. 1 pipe and the fixed sleeve, thus protecting the multiple cables inside the No. 1 pipe.

[0016] 2. This utility model proposes a civil defense conduit structure for laying multiple cables. After the cables are fixed by multiple No. 3 pipes, it can prevent a cable from short-circuiting and being damaged, thus preventing the heat from being transferred to the descending cable and causing the other cables to burn out. After the cable passes through the branch pipe, the arc area of ​​the branch pipe can protect the cable from wear and damage when it bends. When the No. 2 pipe needs to be replaced after long-term use, or when a certain cable is damaged, the pull block is moved up, which drives the locking post and the No. 2 spring to move up, and the locking post slides out from the inside of the top of the No. 2 pipe, so that the No. 2 pipe can be replaced or the cable can be disassembled. This can protect the cable bending point from wear and tear, and at the same time, it is also convenient to replace the No. 2 pipe when it needs to be replaced after long-term use.

[0025] 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.

[0026] Reference Figures 1-6 The present invention provides an embodiment of a civil defense sleeve structure for laying multiple cables, including a support mechanism 1 and a snap-fit ​​mechanism 2. The support mechanism 1 includes a support pipe 101 and a first pipe 105. A fixing sleeve 104 is fixedly connected to the outer wall of the first pipe 105. Two first springs 103 are fixedly connected to the outer walls of multiple fixing sleeves 104. A support block 102 is fixedly connected to multiple first springs 103 away from the first pipe 105.

[0027] The locking mechanism 2 includes a locking post 203, a second tube 206, and multiple third tubes 207. The bottom of the locking post 203 is movably disposed inside the top of the second tube 206. A pull block 201 is fixedly connected to the top of the locking post 203. A second spring 202 is fixedly connected to the bottom of the pull block 201 away from the locking post 203.

[0028] Specifically, the cable passes through the interior of pipe 207. If the wall is damaged by bombing or the wall shakes and squeezes the internal support pipe 101, the support pipe 101 will first provide support and protection. After the support pipe 101 is squeezed and deformed, the pressure will be transmitted through the support block 102 to the first spring 103 and the telescopic rod 106. Finally, the pressure will be transmitted to the fixing sleeve 104 and pipe 105. After the pressure passes through the fixing sleeve 104 and pipe 105, the first spring 103 and the telescopic rod 106 on the other side will contract until the corners of the four support blocks 102 contact to form a ring covering the outside of pipe 105 and fixing sleeve 104, continuing to protect the cable inside pipe 105. The multiple first springs 103 and multiple telescopic rods 106 can absorb external impact and vibration to the greatest extent.

[0029] Reference Figures 1-6 The top of the support tube 101, near the second tube 206, is fixedly connected to the bottom of the two second springs 202. A locking post 203 penetrates the top of the support tube 101 near the second tube 206, and is slidably connected to the inner wall of the support tube 101 near the second tube 206. Four branch tubes 205 are fixedly installed on the inner wall of the second tube 206, spaced 90 degrees apart. The outer wall of the second tube 206 near the support tube 101 is slidably connected to the inner wall of the support tube 101. The inner wall of the support tube 101 and multiple support blocks 102 are located away from the first tube 10. 5. One side is a sliding connection. Multiple No. 3 pipes 207 are fixedly connected to a fixing plate 204 on the side away from No. 1 pipe 105. The ends of the multiple fixing plates 204 away from the multiple No. 3 pipes 207 are fixedly connected to the inner wall of No. 1 pipe 105. Multiple No. 1 springs 103 are internally connected to telescopic rods 106. The ends of the multiple telescopic rods 106 away from No. 1 pipe 105 are fixedly connected to multiple support blocks 102. The ends of the multiple telescopic rods 106 away from the multiple support pipes 101 are fixedly connected to multiple fixing sleeves 104. The outer wall of the support pipes 101 is fixedly provided with a waterproof coating 3.

[0030] Specifically, multiple tubes 207 prevent multiple cables from contacting each other, and prevent heat transfer to other cables and damage when one cable short-circuits. Multiple cables can be diverted to different directions through branch tubes 205. The bends of multiple cables are transitioned by the arc of branch tubes 205 to prevent wear caused by contact between the bends of multiple cables and the corners of the outer wall of the support tube 101. When the cables and tubes 206 wear out after long-term use, pulling the pull block 201 moves upward, causing the locking post 203 and the two springs 202 to move upward. The locking post 203 slides out from the top of the tube 206, allowing the tube 206 to be replaced or the cable to be disassembled. After replacing the tube 206, the locking post 203 is aligned with the hole at the top of the support tube 101 and the tube 206. Under the action of the springs 202, the locking post 203 can be reset to fix the tube 206.

[0031] Working principle: Multiple cables are passed through the No. 3 pipe 207 fixed by the fixing plate 204. The No. 1 pipe 105 can accommodate multiple cables. Cement is poured on the outer wall of the support pipe 101 and the pouring stops near the snap-fit ​​mechanism 2. After the wall is bombed, the internal structure is damaged or the wall shakes and squeezes the internal support pipe 101. After the support pipe 101 is squeezed and collapsed, the force is transmitted to the support block 102. The No. 1 spring 103 and the telescopic rod 106 of the support block 102, when the top support block 102 moves downward, squeeze the bottom No. 1 spring 103 and the telescopic rod 106 until the corners of the four support blocks 102 contact the outside of the No. 1 pipe 105 and the fixing sleeve 104 to form a ring, which continues to support and protect the multiple cables inside.

[0032] Secondly, since the head of the support pipe 101 is located outside the wall, multiple cables can be diverted to different directions through the branch pipe 205 inside the second pipe 206. The branch pipe 205 can ensure that the bends of multiple cables have a rounded transition, preventing damage to the bends of multiple cables. Furthermore, when disassembling a damaged cable or the second pipe 206, the pull block 201 can be moved upward, causing the locking post 203 and the two second springs 202 to move upward, and the locking post 203 can be slid out from the top of the second pipe 206, so that the second pipe 206 can be replaced or the cable can be disassembled.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
