Specific implementation mode

[0028] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0029] Embodiment 1

[0030] As Figures 1 to 7 shown, this embodiment proposes a cable with a butt joint end, including a cable body 1. The two ends of the cable body 1 are respectively fixedly connected with a butt joint end 2 and a locking end 4. A butt joint ring 3 is horizontally slidably connected inside the butt joint end 2. A locking ring 5 is fixedly connected to the outside of one end of the locking end 4. A tightening assembly 6 is arranged inside the locking ring 5. The tightening assembly 6 is used to cooperate with the locking end 4 to form the butt joint between two cable bodies 1;

[0031] Specifically, a through groove is opened at the top of the butt joint end 2. A force-bearing rod is fixedly connected to the top of the butt joint ring 3, and the force-bearing rod is located inside the through groove. With the setting of the through groove, the force-bearing rod can be avoided, so that when a person pulls the force-bearing rod, the butt joint ring 3 can be driven to move accordingly;

[0032] Among them, a limiting slider is fixedly connected to the inner wall of the docking end 2. A linear sliding groove is formed on the outer side of the docking ring 3, and the limiting slider is also slidably connected to the inside of the linear sliding groove. By using the structural cooperation between the limiting slider and the linear sliding groove, the displacement of the docking ring 3 can be effectively guided, ensuring the stability of the docking ring 3 during displacement. A friction pad is fixedly connected to the outer side of the limiting slider to increase the friction between the limiting slider and the sliding groove, so that the docking ring 3 will not slide easily;

[0033] Furthermore, the locking end 4 is of a circular ring structure. A slot for cooperating with the docking ring 3 is formed between the inner wall and the outer wall of the locking end 4. By using the structural cooperation of the slot of the locking end 4, a stable connection with the docking ring 3 can be formed;

[0034] Among them, a sealing ring is fixedly connected to the inside of the slot, and the material of the sealing ring is rubber. By using the setting of the sealing ring, the connection gap between the locking end 4 and the docking ring 3 can be sealed to prevent external water vapor from entering the docking area between the two cable bodies 1;

[0035] Embodiment 2

[0036] As Figures 1 to 7 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a tightening assembly 6;

[0037] In this embodiment, the tightening assembly 6 includes a tightening belt 7, a positioning frame 10 and a limiting hole 11. A through hole 8 and an outlet hole 9 are formed on the outer side of the locking ring 5. One end of the tightening belt 7 passes through the through hole 8 and enters the inside of the locking ring 5, and after changing the direction on the opposite edge parts of the locking ring 5, it passes through the outlet hole 9. Two limiting holes 11 are formed in the middle of the positioning frame 10, and both ends of the tightening belt 7 are slidably connected to the inside of the two limiting holes 11 respectively;

[0038] Preferably, the locking ring 5 is made of an elastic material. By using the material characteristics of the locking ring 5, the tightening belt 7 can drive the locking ring 5 to produce a certain degree of deformation;

[0039] Furthermore, linear sliding rods are fixedly connected to the top and bottom inside the positioning frame 10, and the displacement plate 12 is also slidably connected to the outside of the linear sliding rods. By using the structural cooperation of the linear sliding rods, the displacement of the displacement plate 12 can be stably guided to prevent the displacement plate 12 from rotating along with the threaded section 15;

[0040] The tightening assembly 6 further includes a displacement plate 12, a stop plate 13, a central shaft rod 14 and a threaded section 15. Displacement plates 12 are slidably connected to both the top and bottom inside the positioning frame 10. A stop plate 13 is fixedly connected to one end of the displacement plate 12 close to the limiting hole 11. A central shaft rod 14 is vertically rotatably connected to one side inside the positioning frame 10. Threaded sections 15 are provided at both ends on the outer side of the central shaft rod 14, and the thread directions of the two threaded sections 15 are opposite. And the two displacement plates 12 are respectively threadedly connected to the outer sides of the two threaded sections 15;

[0041] Specifically, a force-receiving knob is fixedly connected to the top of the central shaft rod 14, and anti-slip lines are provided on the outer side of the force-receiving knob. With the arrangement of the force-receiving knob, it enables personnel to conveniently rotate the central shaft rod 14, greatly improving the transmission effect of the threaded section 15.

[0042] A specific application of the above two embodiments is as follows. First, align the locking end 4 at one cable main body 1 with the locking ring 5 at the other cable main body 1. Then, while pushing the docking ring 3 out of the docking end 2, move it into the slot of the locking end 4 to form the docking between the two cable main bodies 1;

[0043] Hold the tightening belt 7 and push the positioning frame 10 to slide on the tightening belt 7, so that the positioning frame 10 contacts the outer wall of the locking ring 5. Then, pull the tightening belt 7 outwards, causing the tightening belt 7 to drive the locking ring 5 to deform, so that the locking ring 5 fits tightly with the docking ring 3 to form the positioning of the docking ring 3. Then rotate the central shaft rod 14. With the arrangement of the two threaded sections 15 with opposite thread directions, it can drive the two displacement plates 12 to displace towards the tightening belt 7, and position the tightening belt 7 inside the limiting hole 11 through the stop plate 13, avoiding uncontrollable sliding between the tightening belt 7 and the positioning frame 10;

[0044] And when the cable main body 1 does not need to be docked, the docking ring 3 can be moved into the docking end 2, so that the normal use of the cable main body 1 will not be affected by the existence of the docking ring 3.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
