DETAILED DESCRIPTION

[0024] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 6 As shown, this specific embodiment adopts the following technical solution: it comprises a sheath body 1, the sheath body 1 is composed of an upper sheath 1-1 and a lower sheath 1-2, and the lower part of the upper sheath 1-1 is movably opposed to the lower sheath 1-2;

[0026] It also contains:

[0027] Mounting strips 2, the mounting strips 2 are several in number, and are respectively fixed on the outer ring wall of the sheath body 1 with equal fillets. The outer ring wall of the sheath body 1 is provided with several wear-resistant strips 3 with equal fillets. The wear-resistant strips 3 are clamped on the mounting strips 2. The wear-resistant strips 3 are made of PE material and have good insulation and friction resistance. Through the protection of the wear-resistant strips 3, the wear caused by the contact between the sheath body 1 and other objects can be fully reduced. The upper sheath 1-1 and the lower sheath 1-2 are connected by a splicing mechanism 8;

[0028] The limiting plates 4 are several in number and are respectively screwed and connected at the two ends of the several mounting strips 2 through shafts and bearings. Three springs 5 ​​are fixedly arranged in the limiting plates 4. A synchronous plate 6 is movably arranged in the limiting plates 4. One end of the spring 5 is fixedly connected to the synchronous plate 6. Two guide rods 12 are fixedly arranged in the limiting plates 4. The guide rods 12 are movably arranged on the synchronous plate 6. The guide rods 12 can provide guidance for the movement of the synchronous plate 6, so that the movement process of the synchronous plate 6 is more stable.

[0029] The limit block 7 is a plurality of limit blocks 7, which are respectively fixedly arranged on both sides of the side walls of the plurality of synchronization plates 6. One end of the limit block 7 passes through the limit plate 4 and is movably abutted in the limit groove 14 provided at the end of the wear-resistant strip 3. A sealing ring 13 is fixedly arranged in the embedded groove provided on the side wall of the limit plate 4 and located outside the limit block 7. The sealing ring 13 is movably abutted against the side wall of the wear-resistant strip 3. The sealing ring 13 can improve the sealing performance of the gap between the limit plate 4 and the wear-resistant strip 3 to prevent rainwater from penetrating into the limit plate 4.

[0030] The splicing mechanism 8 comprises:

[0031] Positioning plates 8-1, the positioning plates 8-1 are several, respectively fixed in the strip grooves opened on the left and right sides of the upper part of the lower sleeve 1-2, and the positioning plates 8-1 are movably clamped in the rectangular grooves 9 opened in the lower part of the upper sleeve 1-1, and the left and right sides of the side walls of the upper sleeve 1-1 are both provided with control grooves 10 intersecting with the several rectangular grooves 9;

[0032] There are two control rods 8-2, which are movably inserted in two control grooves 10 respectively. Several limit rods 8-3 are fixedly set on the control rod 8-2. The protrusions on the limit rods 8-3 are clamped in the through holes 8-4 opened on the positioning plate 8-1. The front end of the control rod 8-2 is screwed with a threaded rod 11 through a thrust ball bearing. The threaded rod 11 is screwed and inserted on the front side of the upper sleeve 1-1 through a threaded connection. The threaded rod 11 can limit the position of the control rod 8-2 to prevent the control rod 8-2 from moving at will during normal use of the sleeve.

[0033] When using the utility model, the upper sheath 1-1 and the lower sheath 1-2 are respectively sleeved on the upper and lower sides of the cable, and the positioning plate 8-1 is inserted into the rectangular groove 9. Then, the control rod 8-2 can be driven to move backward through the threaded rod 11, and the control rod 8-2 drives the limiting rod 8-3 to move backward, so that the protrusion on the limiting rod 8-3 is clamped into the through hole 8-4, and then the threaded rod 11 is rotated to make the threaded rod 11 screwed to the upper sheath 1-1 through the thread, so that the sheath body 1 is installed and fixed on the cable. The protection of the wear-resistant strip 3 can reduce the contact between the sheath body 1 and other objects, and reduce the wear of the sheath body 1. When the wear-resistant strip 3 is severely worn, the limiting plate 4 can be rotated so that the limiting plate 4 drives the limiting block 7 to rotate. Move out of the limit groove 14. At this time, the limit block 7 will be squeezed into the limit plate 4, and under the action of the synchronous plate 6, the spring 5 will be compressed. At the same time, when the limit block 7 on either side is squeezed, the limit block 7 on the other side will also be synchronously moved into the limit plate 4 through the cooperation of the synchronous plate 6. At this time, after the wear-resistant strip 3 loses the limit of the limit block 7, the wear-resistant strip 3 can be moved in the opposite direction of the sleeve body 1, so that the wear-resistant strip 3 is detached from the mounting strip 2, and then the other wear-resistant strip 3 is clamped on the mounting strip 2, and then the limit plate 4 is rotated in the opposite direction, so that the limit plate 4 drives the limit block 7 to rotate in the opposite direction to the position of the limit groove 14. At this time, the spring 5 resets and stretches, and drives the limit block 7 to be clamped in the limit groove 14 through the synchronous plate 6, so as to limit the installed wear-resistant strip 3.

[0034] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0035] 1. The wear-resistant strips 3 with equal fillet distribution can fully reduce the wear caused by the contact between the jacket body 1 and other objects, and the cooperation of the mounting strip 2, the limit plate 4, the spring 5, the synchronous plate 6 and the limit block 7 is also conducive to the replacement of the wear-resistant strips 3 with serious wear;

[0036] 2. Through the cooperation of the splicing mechanism 8, the sheath body 1 can be conveniently disassembled and assembled on the cable.

[0037] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
