[0011] Preferably, the cover body is made of metal material, and the outer surface of the cover body is smooth.

[0012] Preferably, the inside of the insulating shield gradually decreases from right to left, and the insulating shield is a hollow structure.

[0013] Preferably, the sealing sleeve and the clamping sleeve are both made of rubber material, and the sealing sleeve and the clamping sleeve are both annular structures.

[0014] (Three) beneficial effects

[0015] The utility model provides a kind of cable closed cover, with the following beneficial effects:

[0016] (1), the cable closed cover, by being provided with screw sleeve, merging petal, clamping sleeve and insulating shield, in the use process, staff inserts the one end of cable into the sealing sleeve of sleeve mouth, and then cable is passed through screw sleeve and merging petal, when installing, staff inserts screw sleeve and merging petal into the cover mouth of cover body, so that the one end of cable is pressed against insulating shield, and then staff rotates butt joint sleeve, butt joint sleeve drives screw sleeve and merging petal to rotate respectively, and screw sleeve is connected with cover mouth by screw thread, at this time, screw sleeve pushes merging petal, and merging petal extrudes insulating shield, at this time, merging petal will be inwards, at this time, the clamping sleeve on merging petal will be clamped to cable, so that closed cover can be equipped with multiple models of cable, so as to improve the adaptability of closed cover.

[0022] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments, and based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0023] Please refer to Figures 1-4 The utility model provides a technical scheme: a cable closed cover, including cover body 1, the one end of cover body 1 is equipped with cover mouth 2, the inside installation of cover mouth 2 has insulating shield 9, the one end of cover body 1 is connected with the screw sleeve 6 through cover mouth 2, the one end of screw sleeve 6 is fixedly connected with the butt joint sleeve 3, the one end of butt joint sleeve 3 is equipped with sleeve mouth 4, the inside installation of sleeve mouth 4 has sealing sleeve 5, the other end of screw sleeve 6 is fixedly connected with the merging petal 7, the inside installation of merging petal 7 has the clamp sleeve 8.

[0024] Further, the merging petal 7 is provided with four, the size of the four merging petals 7 is same, when the screw sleeve 6 pushes the merging petal 7, and the merging petal 7 extrudes the insulating shield 9, at this time, the merging petal 7 will be inwards and will be folded, at this time, the clamp sleeve 8 on the merging petal 7 will hold the cable, so that the closed cover can be equipped with various models of cable.

[0025] Further, the screw sleeve 6 includes the butt joint sleeve 3 at one end of the screw sleeve 6 and the merging petal 7 at the other end of the screw sleeve 6, which are integrated structures, and the integrated butt joint sleeve 3, screw sleeve 6 and merging petal 7 are convenient for production and manufacture.

[0026] Further, the diameter of the screw sleeve 6 is matched with the inner diameter of the cover mouth 2, and the screw sleeve 6 is threadedly connected with the cover mouth 2, so that the screw sleeve 6 and the cover mouth 2 can be more tightly connected in the process of threadedly connecting.

[0027] Further, the cover body 1 is processed from metal material, and the outer surface of the cover body 1 is smooth, so that the cover body 1 processed from metal material is more solid and durable and is not easy to be damaged.
