Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a flame-retardant cable with a cable protection device. Background Technique

[0002] A flame-retardant cable refers to a cable that, under specified test conditions, when the specimen is burned and the test fire source is removed, the spread of the flame is only within a limited range, and the residual flame or afterglow can self-extinguish within a limited time. Its fundamental characteristic is that it may be burned out and unable to operate in case of a fire, but it can prevent the spread of the fire. Generally speaking, in case of a fire in the wire, it can limit the combustion to a local area, without spreading, protect various other devices, and avoid causing greater losses.

[0003] However, in the prior art, when installing a flame-retardant cable, in order to protect the connection of the flame-retardant cable, a protective shell is often set to protect the connection. However, the installation steps of the existing protective shell are cumbersome, time-consuming and laborious, and the heat dissipation effect of the flame-retardant cable is affected after the protective shell is installed, resulting in problems such as inconvenient installation with the cable main body, single heat dissipation method and poor heat dissipation effect. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the utility model to solve its technical problems is: a flame-retardant cable with a cable protection device, including: a protective shell; a cable, the cable is arranged inside the protective shell; an observation board, the outer wall of the observation board is fixedly connected to the top end of the protective shell; a fixing device, the outer wall of the fixing device is fixedly connected to the outer wall of the protective shell; a circulation mechanism, the outer wall of the circulation mechanism is fixedly connected to the inner wall of the protective shell; the fixing device includes a fixing ring, the inner wall of the fixing ring is rotatably connected with a rotating ring, the outer wall of the rotating ring is rotatably connected with a rotating handle, the outer wall of the rotating handle is rotatably connected with a telescopic ring, one end of the rotating handle away from the telescopic ring is rotatably connected with a guide post, the outer wall of the rotating ring is fixedly connected with a toggle rod, and a tooth groove is opened on the outer wall of the fixing ring.

[0005] Preferably, the rotating handles are annularly arranged along the central axis of the fixing ring, the outer wall of the fixing ring is fixedly connected to the outer wall of the protective shell, a limiting groove is opened on the outer wall of the fixing ring, and the outer wall of the guide post is slidably connected to the inner wall of the limiting groove. The guide post on the rotating handle is restricted by the limiting groove on the fixing ring, so that when the rotating ring rotates, it will drive the rotating handle to rotate. As the rotating handle moves, it squeezes the telescopic ring, causing the telescopic ring to contract.

[0006] Preferably, the outer wall of the toggle rod is slidably connected with a block, and the outer wall of the block is fixedly connected with a push spring. The outer wall of the toggle rod is slidably connected to the inner wall of the fixed ring, the top of the push spring is fixedly connected to the top of the toggle rod, and the outer wall of the block is slidably connected to the inner wall of the tooth groove. When the block is released, the block moves back to its original position under the action of the push spring and is stuck in the tooth groove, so that the toggle rod cannot drive the rotating ring to rotate. With the curved circulation pipe, rainwater will be directly discharged from the air inlet pipe and cannot enter the circulation pipe, so that rainwater cannot enter the inner cavity of the protective shell to corrode the cable.

[0007] Preferably, the circulation mechanism comprises an air inlet pipe, the outer wall of the air inlet pipe is fixedly connected to a circulation pipe, and the middle outer wall of the circulation pipe is fixedly connected to an output pipe. The outer walls of the air inlet pipe, the circulation pipe and the output pipe are fixedly connected to the inner wall of the protective shell, and the air inlet pipe is symmetrically arranged at both ends of the circulation pipe.

[0008] The beneficial effects of the utility model are as follows:

[0009] 1. The utility model protects the connection of the cable by providing a protective shell. The toggle rod is pulled to drive the rotating ring to rotate in the fixed ring, and the rotating handle is driven to rotate. As the rotating handle moves, the telescopic ring is squeezed to shrink until the telescopic ring contacts the cable, thereby completing the fixation of the protective shell and the cable. At the same time, the protective shell is movably arranged in the protective shell, and the detachable structure is convenient for disassembly and maintenance.

[0010] 2. The utility model sets a circulation mechanism, and air enters through the air inlet pipe, and the air enters the inner cavity of the protective shell through the output pipe, so as to dissipate heat to the internal cables. When it rains, rainwater will be discharged directly from the air inlet pipe through the curved circulation pipe and cannot enter the circulation pipe, so that rainwater cannot enter the inner cavity of the protective shell to corrode the cables, thereby achieving a waterproof effect in the process of exhaust and heat dissipation.

[0019] The rotating handles 33 are annularly arranged along the central axis of the fixed ring 31, the outer wall of the fixed ring 31 is fixedly connected to the outer wall of the protective shell 1, the outer wall of the fixed ring 31 is provided with a limit groove 36, and the outer wall of the guide post 35 is slidably connected to the inner wall of the limit groove 36. The rotating ring 32 rotates inside the inner wall of the fixed ring 31. Under the restriction of the limit groove 36 on the fixed ring 31 by the guide post 35 rotatably connected to the rotating handle 33, when the rotating ring 32 rotates, it will drive the rotatably connected rotating handle 33 to rotate. As the rotating handle 33 moves, it presses the telescopic ring 34, causing the telescopic ring 34 to contract.

[0020] The outer wall of the toggle rod 38 is slidably connected with a block 310, and the outer wall of the block 310 is fixedly connected with a push spring 39. The outer wall of the toggle rod 38 is slidably connected with the inner wall of the fixed ring 31, the top of the push spring 39 is fixedly connected with the top of the toggle rod 38, and the outer wall of the block 310 is slidably connected with the inner wall of the tooth groove 37.
