Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0022] This utility model provides an improved quick-installation device for explosion-proof cable head housings. The technical solution of this utility model is as follows:

[0023] like Figures 1-4 As shown, a quick-installation device for an explosion-proof cable head housing includes two housings 1. Each housing 1 has a housing groove 2 at the center of its outer wall. A fixing component 4 is installed inside each of the two sets of housing grooves 2. The fixing component 4 includes a collar 41, a fixing plate 42, and a rotating block 45. The two collars 41 are located on the outer walls of the two housings 1 respectively. The two sets of fixing plates 42 are fixedly installed at both ends of the collars 41. An inner cavity 6 is formed inside the housing 1. A limit component 7 is installed inside the inner cavity 6. The interior of both sets of housings 1 is made of insulating material. The diameter of the inner cavity at both ends of the housing is slightly larger than that of the cable 8, and the sealing effect is achieved through the elasticity of the cable 8.

[0024] Furthermore, the fixing component 4 also includes a rotating shaft 44 and a threaded rod 47. The rotating shaft 44 is disposed inside one set of fixing plates 42, and the other set of fixing plates 42 has a plate groove 43 in the middle. The threaded rod 47 is fixedly installed on one end of the rotating block 45, and the rotating block 45 is rotatably mounted on the rotating shaft 44. When needed, the rotating block 45 is rotated to move the threaded rod 47 into the plate groove 43.

[0025] Furthermore, the fixing component 4 also includes a shaft hole 46 and a nut 48. The shaft hole 46 is opened at one end of the rotating block 45 and is adapted to the rotating shaft 44. The nut 48 and the threaded rod 47 are respectively fixedly connected to the two ends of the two sets of collars 41, and the threaded rod 47 is adapted to the nut 48.

[0026] Furthermore, the limiting component 7 includes a bracket 71, a support ring 72, and protrusions 73. The bracket 71 is fixedly installed inside the inner cavity 6, and the support ring 72 is fixedly installed on the upper end of the bracket 71. The inner wall of the support ring 72 is provided with several sets of protrusions 73, which can increase the friction force on the cable 8.

[0027] Furthermore, the limiting component 7 also includes a positioning groove 74 and a positioning block 75. The positioning groove 74 is opened at one end of one set of housings 1, and the positioning block 75 is fixedly installed at one end of another set of housings 1. The positioning groove 74 and the positioning block 75 are adapted to each other.

[0028] Furthermore, sealing grooves 3 are provided at both ends of the housing 1, and small collars 5 are installed on the outer wall of the sealing grooves 3. The small collars 5 have the same structure as the fixing component 4, and the small collars 5 can fix the two ends of the housing.

[0029] The specific working method is as follows: First, wrap some silicone rubber sealing strips or armor tape around the outer wall of the cable 8, and then wrap several layers of waterproof tape around the sealing strips for fixation. Place one set of housing 1 on the ground, place the pre-treated cable 8 inside the housing 1, and then cover it with another set of housing 1 so that the positioning groove 74 between the two sets of housing 1 matches the positioning block 75, which can achieve the effect of pre-installation. Then, put two sets of collars 41 inside the housing groove 2, rotate the rotating block 45 around the rotating shaft 44, so that the threaded rod 47 on the rotating block 45 is embedded in the plate groove 43, and then fix it with nuts 48. The sealing grooves 3 at both ends of the housing 1 are fixed with small collars 5 so that the two sets of housing 1 clamp the cable 8. After installation, the support ring 72 set in the inner cavity 6 can limit the cable 8. The protrusion 73 set on the support ring 72 can increase the friction of the cable 8, which can effectively prevent the cable 8 from being pulled out or moved from one end under the influence of external force.
