[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 3 As shown, this utility model provides a stepped sealing sleeve device for cable joints, including a cable 1 and a sealing sleeve assembly installed on the outside of the cable 1. The sealing sleeve assembly includes a rubber sleeve 2 sleeved on the outside of the cable 1 and an annular positioning groove 3 constructed on the outer wall of the rubber sleeve 2. The rubber sleeve 2 wraps around the outside of the cable 1 to provide it with sealing protection, and a clamping ring 4 is sleeved on the inner side of the positioning groove 3. The clamping ring 4 tightly fixes the corresponding side of the rubber sleeve 2 to the outer wall of the cable 1 to ensure the sealing at that point. The front ends of the upper and lower parts of the clamping ring 4 are integrally formed with fixing parts 5, and a fastening screw 6 is screwed between the two fixing parts 5. The fastening screw 6 can be used to fix the cable joint. Tighten the upper and lower parts of the clamping ring 4, and unscrew the fastening screw 6 to remove the clamping ring 4, thereby detaching the rubber sleeve 2 from the side wall of the cable 1. A connecting ring 7 is bonded to the side of the rubber sleeve 2 away from the cable 1, and a sealing tube 8 is integrally formed on the inner side of the connecting ring 7. The rubber sleeve 2 is fixed to the corresponding side of the sealing tube 8 through the connecting ring 7. The sealing tube 8 provides sealing protection for the cable 1. A connecting sleeve 9 is threaded to the outer wall of the side of the sealing tube 8 away from the connecting ring 7. The left end of the connecting sleeve 9 is connected to the current sealing sleeve assembly, and the right end is used to connect to another set of sealing sleeve assemblies. The sealing sleeve assembly at the right end is used to provide sealing protection for the cable 1 at the right end.

[0022] Specifically, a reinforcing ring 10 is bonded to the side of the rubber sleeve 2 away from the connecting ring 7, and the reinforcing ring 10 is flush with the outer side of the rubber sleeve 2, which can provide structural strength to that side of the rubber sleeve 2 and prevent damage to the corresponding side of the rubber sleeve 2.

[0023] Furthermore, the rubber sleeve 2 has an annular groove 11 on the side near the connecting ring 7, and a waterproof adhesive layer is bonded to the inner side of the groove 11, which fixes the rubber sleeve 2 to the corresponding side of the connecting ring 7.

[0024] Furthermore, the side wall of the connecting ring 7 has an opening 12 corresponding to the groove 11, and a rubber plug is glued to one side of the opening 12. The opening 12 facilitates the injection of glue, and after the injection is completed, the opening 12 is blocked by the rubber plug.

[0025] It is worth noting that the front and rear outer walls of the connecting sleeve 9 are both constructed with force-applying grooves, and rubber pads 13 are bonded to the inner side of the force-applying grooves. The friction can be increased by the rubber pads 13 on both sides, making it easier to apply force to screw the connecting sleeve 9 between the outer sides of the two sealing tubes 8.

[0026] It is worth noting that the hoop 4 and the fastener 5 are die-cast integral structures, which have high structural strength and are not easily damaged. The connecting ring 7 and the sealing tube 8 are injection molded integral structures, which are more durable and not easily damaged.

[0027] It is worth noting that the side wall of the fastening screw 6 is fitted with a washer (not shown in the figure), and the washer is supported between the head of the fastening screw 6 and the corresponding side of the fastener 5, which can prevent the fastening screw 6 from being tightened too much and making it difficult to unscrew.

[0028] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0029] Working principle: First, pass the left cable 1 through the rubber sleeve 2 and the sealing tube 8 and extend it to the inside of the connecting sleeve 9. Then, fit the clamp 4 into the positioning groove 3 and tighten the fastening screw 6 to fix it. Next, pass the right cable 1 through the rubber sleeve 2 and the sealing tube 8 and connect it to the left cable 1. Then, fix the right clamp 4. Finally, tighten the connecting sleeve 9 to screw it between the outside of the two sealing tubes 8. Since the sealing tube 8 and the connecting sleeve 9 are connected by threads and the clamp 4 is fixed by the fastening screw 6, it can be repeatedly disassembled and assembled. It is a non-disposable installation method, which is more environmentally friendly. Tightening the fastening screw 6 and the connecting sleeve 9 is enough to complete the installation of the device and the two cables 1. When disassembling, you only need to tighten the two. The overall operation process is relatively simple and more convenient to use.
