[0023] 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.

[0024] like Figures 1 to 5 As shown, this utility model provides a waterproof sealing structure for a cable joint, including two left-right hinged first protective sleeves 1 and two top-bottom hinged second protective sleeves 2. The two top-bottom hinged second protective sleeves 2 can cover the joint of the two left-right hinged first protective sleeves 1 to improve the sealing effect. The second protective sleeves 2 are fitted onto the outside of the first protective sleeves 1. A semi-circular limiting strip 3 is welded to the inner wall of the second protective sleeve 2, and the first protective sleeve 1 is located between the two limiting strips 3. The two limiting strips 3 can position the installation position of the two first protective sleeves 1 and also improve the sealing effect at that point. For sealing effect, the left side of the second protective sleeve 2 is integrally formed with a fixing member 4. The fixing member 4 has a fixing hole 5 in the middle, and a fixing screw 6 is screwed between the corresponding fixing holes 5. The two fixing members 4 can be fixed by fixing screw 6. After fixing the fixing members 4 on the front and rear sides, the two second protective sleeves 2 can be fixed. The tail of the fixing screw 6 is screwed with a nut 7, which can ensure the stability of the fixing screw 6 and ensure that the connection with the corresponding two fixing members 4 will not be loose. The nut 7 abuts against the corresponding side of the fixing member 4. An installation component is installed at the bottom of the lower side of the second protective sleeve 2.

[0025] Specifically, the mounting components include a mounting plate 9 integrally formed at the bottom of the lower second protective sleeve 2 and two screws 10 symmetrically screwed to the top of the mounting plate 9, the screws 10 being able to be screwed relative to the mounting plate 9.

[0026] Furthermore, a reinforcing plate 11 is mounted on the bottom of the screw 10 via a bearing. A guide rod 12 is threadedly connected to one side of the top of the reinforcing plate 11. The threaded connection facilitates disassembly and assembly, and the guide rod 12 is movably inserted into the corresponding side of the mounting plate 9. The guide rod 12 can prevent the reinforcing plate 11 from deflecting along with the screw 10.

[0027] Furthermore, the top of the reinforcing plate 11 has two symmetrical reinforcing holes 13 opposite to the screw 10. Bolts can be screwed into the reinforcing holes 13 to fix it to the external structure. The top of the screw 10 is connected to a circular gripper 14 by screws, which makes it easy to apply force to tighten the screw 10.

[0028] It is worth noting that the second protective sleeve 2 and the fastener 4, as well as the second protective sleeve 2 and the mounting plate 9, are all injection molded as a single unit. The injection molded structure has higher structural strength, is less prone to damage and breakage, and is more durable.

[0029] It is worth noting that a washer (not shown in the figure) is fitted on the side wall of the fixing screw 6, and the washer is supported between the head of the fixing screw 6 and the corresponding side of the fastener 4, so as to prevent the fixing screw 6 from being tightened too much, which would make it difficult to unscrew.

[0030] It is worth mentioning that a waterproof layer 8 is bonded to the inside of the first protective sleeve 1, and the waterproof layer 8 is flush with the corresponding side of the first protective sleeve 1, which can improve the waterproof sealing effect of the first protective sleeve 1.

[0031] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0032] Working principle: First, connect the cables on both sides, then connect the two first protective sleeves 1 as follows: Figure 3 Sleeve it onto the sidewalls of the two cables that have already been wired, then attach the two second protective sleeves 2 as follows: Figure 1 The device is fitted onto the outside of the first protective sleeve 1. Then, the fixing screw 6 is screwed into the corresponding fixing hole 5 and tightened. Next, the nut 7 is tightened at the end of the fixing screw 6 to complete the installation. If it is necessary to increase the stability of the equipment after installation, the height of the reinforcing plate 11 can be adjusted by turning the screws 10 on both sides so that the reinforcing plate 11 is close to the external structure. Finally, the bolts are screwed between the reinforcing hole 13 and the external structure to increase the stability of the equipment.
