Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example one

Fig. 1 is a schematic structural view of a cable bushing according to the present invention in an unfolded state, fig. 2 is a schematic structural view of the cable bushing according to the present invention in a closed state, fig. 3 is a schematic axial structural view of the cable bushing according to the present invention in a closed state, and referring to fig. 1, fig. 2 and fig. 3, this embodiment provides a cable bushing comprising a bushing body 1 and a fastening device 2, the bushing body has a first connecting end 11 and a second connecting end 12 corresponding to the first connecting end 11, the fastening device 2 includes a male buckle 21 and a female buckle 22, the male buckle 21 is fixedly connected to the first connecting end 11, the female buckle 22 is fixedly connected to the second connecting end 12, the male buckle 21 is operatively connected to the female buckle 22, the bushing body is integrally connected by the male buckle and the female buckle, so as to wrap a cable, and when the cable bushing needs to be replaced, only the male buckle and the female buckle need to be separated, the cable threading sleeve can be taken down very quickly, and the equipment for connecting the cables does not need to be stopped. The male buckle and the female buckle may be commonly used buckles, and in this embodiment, no specific limitation is imposed.

Example two

As another embodiment of the present invention, different from the previous embodiment, the male buckle 21 of this embodiment includes a first protrusion 211 and a second protrusion 212 connected in sequence, the first protrusion 211 is connected with the first connection end 11, and the width of the first protrusion 211 is smaller than the width of the second protrusion 212, the female buckle 22 includes a first buckle plate 221 and a second buckle plate 222, the first buckle plate 221 is connected with the second connection end 12, the first buckle plate 221 is provided with a first notch, the second buckle plate 222 is provided with a second notch, the second notch is communicated with the first notch, and the width of the first notch is smaller than the width of the second notch, the second protrusion 212 is operatively embedded in the second notch of the second buckle plate 222, and the first protrusion 211 is operatively embedded in the first notch of the first buckle plate 221. Because the width of first lug 211 and second lug 212 is different, form first step face in junction between them, the width of first notch and second notch is also different, can form the second step face in junction between them, and first step face and second step face can butt each other to prevent the separation of convex buckle 21 and concave buckle 22, guarantee that the cable threading sleeve cover can have certain stability after establishing on the cable.

Further, the cross-section of first lug 211 is square, the cross-section of second lug 212 is semi-circular, the semicircle plane and the first lug 211 fixed connection of second lug 212, the cross-section of first notch is square, the cross-section of second notch is semi-circular, the semicircle plane and the first notch of second notch are linked together, through setting up semicircular second lug 212 and second notch, make the semicircle cambered surface of both junctions can effectual entering that prevents the dust, because the cambered surface is crooked and longer for the plane route, consequently the dust in operational environment is more difficult to get into cable threading sheathed tube inside.

It should be noted that the cross section of the second protrusion 212 may be triangular, and the cross section of the second notch may also be triangular, wherein the plane where the longest side of the triangle of the second protrusion 212 is located is fixedly connected with the first protrusion 211, and the plane where the longest side of the triangle of the second notch is located is communicated with the first notch. The other two sides of the triangle also make it less likely that dust will enter the interior of the cable transit sleeve.

Furthermore, the opening directions of the first notch and the second notch of the female buckle 22 and the first convex block 211 and the second convex block 212 of the male buckle 21 face the same side of the sleeve body 1, and after the cable threading sleeve is wound outside the cable, the male buckle 21 and the female buckle 22 can be easily buckled.

Further, the length of the male buckle 21 and the female buckle 22 is the same as that of the sleeve body 1, so that the length of the cable threading sleeve required actually can be selected according to the length of the actual cable.

Further, the sleeve body 1 and the fastening device 2 are integrally formed, and both the sleeve body 1 and the fastening device 2 are made of an insulating material, such as plastic, polyester, metal, and the like.

The embodiment of the specification provides a cable threading sleeve pipe, including sleeve pipe body and fastener, the sleeve pipe body has first link and the second link that corresponds with first link, fastener includes protruding knot and concave knot, protruding knot and first link fixed connection, concave knot and second link fixed connection, protruding knot maneuverability is connected with concave knot, be connected with the cooperation of concave knot through protruding knot, link into an integrated entity the sleeve pipe body, thereby wrap up the cable, and when needing to be changed utensil cable threading sleeve pipe, only need part protruding knot and concave knot, then can be very quick take off cable threading sleeve pipe, cable connection's equipment need not to shut down, be equipped with fine practicality.

The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. It should be noted that, for those skilled in the art, without departing from the principle of the present application, several improvements and modifications can be made, and these improvements and modifications should also be construed as the protection scope of the present application.
