Detailed Implementation

[0021] Please see Figure 1-6 As shown, this application provides a technical solution: a cross-linked cable cold shrink waterproof flame retardant straight intermediate connection joint, including a tube body 1, joints 3 disposed on both sides of the tube body 1, and a connection mechanism between the tube body 1 and the joints 3. The connection mechanism includes a movable clamp 31 disposed on the tube body 1 and a boss 32 disposed on the inner side of the joint 3, with the clamp 31 clamped on the surface of the boss 32.

[0022] In a preferred embodiment, a groove 11 is provided on one side of the tube body 1, and a clamp 31 is disposed in the groove 11. A baffle 33 is provided on the side of the groove 11 near the center, and a notch 36 is provided on the baffle 33. A spring 34 is also provided between the clamp 31 and the baffle 33. A push rod 35 extending out of the tube body 1 is also provided on the side of the baffle 33 away from the spring 34. When working, the push rod 35 pushes the clamp 31, and part of the clamp 31 extends out from the notch 36 of the baffle 33 and the groove 11 and abuts against the boss 32.

[0023] In a preferred embodiment, a threaded hole 12 is provided on one side of the groove 11, and a matching thread is provided on the push rod 35. The push rod 35 passes through the threaded hole 12 and abuts against one side of the chuck 31.

[0024] The push rod 35 is similar to a fixed-base type, with a groove on one side that can be tightened with a screwdriver.

[0025] In a preferred embodiment, a slot 321 is also provided on the boss 32, and the head 31 is engaged in the slot 321.

[0026] In the preferred embodiment, the baffle 33 is located at the center of the groove 11 and has notches 36 on both sides of the groove 11, and the clip 31 extends out from the notches 36.

[0027] The chuck 31 is also provided with a guide groove 312, and the baffle 33 is provided with a matching guide platform, and the chuck 31 moves along the guide platform.

[0028] The working principle of the connecting mechanism is as follows: when the connector 3 is connected to the tube body 1, the push rod 35 is screwed in. The push rod abuts against one side of the clamp 31, pushing the clamp 31 out from the notch 36 and abutting against the groove 321. In this way, the connector 3 cannot be separated from the tube body 1. When it is necessary to disassemble the connector 3, the push rod 35 is screwed out, and the clamp 31 retracts under the action of the spring 34, so that the connector 3 can be pulled out of the tube body 1.

[0029] In a preferred embodiment, an arc-shaped section 311 matching the card slot 321 is provided at the front end of the card head 31.

[0030] In a preferred embodiment, a coating mechanism 2 is further provided on the surface of the pipe body 1. The coating mechanism 2 includes a waterproof coating 21, a sun-proof and heat-insulating coating 22, a flame-retardant coating 23, and a fluorescent coating 24. The fluorescent coating 24 covers the surface of the pipe body 1, and the flame-retardant coating 23 covers the surface of the fluorescent coating 24. The sun-proof and heat-insulating coating 22 covers the surface of the flame-retardant coating 23, and the waterproof coating 21 covers the surface of the sun-proof and heat-insulating coating 22.

[0031] When the waterproof coating 21, the sun-proof and heat-insulating coating 22, and the flame-retardant coating 23 are used up, the fluorescent coating 24 will be exposed to the outside world to remind workers to re-spray in time. The waterproof coating 21 helps to prevent rainwater from entering. The sun-proof and heat-insulating coating 22 can prevent the pipe body 1 from aging due to sun exposure in the hot summer. The flame-retardant coating 23 helps to prevent external fire sources from entering, which helps to extend the service life.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
