[0002] In existing technologies, gaps exist at the connection between the cable and the outer casing, and the cable and the outer casing are two separate structures. This can easily lead to relative displacement during use, causing mechanical damage and stress on the cable, affecting its safety. This is especially true during the assembly and use of the cable and the outer casing, which can easily create safety hazards.

[0003] The prior art discloses a sealing structure and sealing method for wire lead-out holes (CN201110135185.3). Although it initially achieves a dustproof sealing effect, the sealing structure for wire lead-out holes in the prior art still has the following defects:

[0004] Although a preliminary seal has been achieved, the wires in the existing sealed structure are still prone to relative displacement and mechanical wear under the action of external forces.

[0005] The assembly and disassembly of the existing through-hole structure are not convenient enough;

[0006] The structure relies solely on elastic sealing and lacks rigid limiting support, making it susceptible to displacement due to external forces, resulting in poor stability of the assembled structure. Utility Model Content

[0012] In a preferred embodiment of this utility model, a sealing ring platform is further provided on the sealing hose. The sealing ring platform is located outside the sealing ring platform, and the sealing ring platform is in elastic contact with the inner wall of the locking nut.

[0013] In a preferred embodiment of this utility model, the connection between the first sealing ring platform and the second sealing ring platform is a transition slope, and the end of the guide tube can abut against the transition slope.

[0014] In a preferred embodiment of this utility model, a fixing ring for fixing the wire is housed inside the outer shell. The fixing ring is located in the inner cavity, and the outer diameter of the fixing ring is larger than the diameter of the guide tube hole of the outer shell.

In the absence of conflict, the embodiments of the present invention and the technical features therein can be combined with each other.

[0027] The term "and / or" simply describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " generally indicates that the preceding and following related objects have an "or" relationship. Example 1

[0028] like Figure 1 As shown, this utility model discloses an electrical wire sealing structure, including a housing 3, a guide tube 31 disposed on the housing 3, the guide tube 31 communicating with the inner cavity 32 of the housing 3, an electrical wire 5 passing through the guide tube 31 into the inner cavity 32 of the housing 3, and a sealing hose 2 sleeved on the outside of the electrical wire 5. The sealing hose 2 is embedded between the electrical wire 5 and the guide tube 31; a locking nut 1 is sleeved on the outside of the guide tube 31, the locking nut 1 confining the sealing hose 2 and the electrical wire 5 within the guide tube 31 of the housing 3. Example 2

[0029] like Figure 1As shown, this utility model discloses an electrical wire sealing structure, including a housing 3, a guide tube 31 provided on the housing 3, the guide tube 31 communicating with the inner cavity 32 of the housing 3, an electrical wire 5 passing through the guide tube 31 into the inner cavity 32 of the housing 3, and a sealing hose 2 sleeved on the outside of the electrical wire 5. The sealing hose 2 is embedded between the electrical wire 5 and the guide tube 31; a locking nut 1 is sleeved on the outside of the guide tube 31, and the locking nut 1 is threadedly connected to the outwardly extending guide tube 31 on the housing 3; the locking nut 1 confines the sealing hose 2 and the electrical wire 5 within the guide tube 31 of the housing 3. Furthermore, the housing 3 provides support and protection for the entire electrical wire sealing structure, forming a relatively enclosed space. In a further embodiment, the housing 3 includes a box body and a cover body; after assembling the electrical wire sealing structure with the box body, the cover body is then assembled and sealed with the box body.

[0030] Specifically, one end of the sealing hose 2 is inserted into the bore of the guide tube 31, and the other end of the sealing hose 2 contacts the inner wall of the locking nut 1. One end of the sealing hose 2 is provided with a second sealing ring platform 23, and the inner wall of the guide tube 31 is provided with an abutment protrusion 311 that abuts against the cross-section of the second sealing ring platform 23. The other end of the sealing hose 2 is a tube opening 21. The sealing hose 2 is also provided with a first sealing ring platform 22, which is located outside the second sealing ring platform 23 and elastically contacts the inner wall of the locking nut 1. The junction of the first sealing ring platform 22 and the second sealing ring platform 23 is a transition slope, and the end of the guide tube 31 can abut against the transition slope. The side of the second sealing ring platform 23 that abuts against the abutment protrusion 311 is a gradually tapering outward-extending guide slope. Furthermore, the sealing hose 2 is one of the core components for achieving the sealing function in the wire sealing structure. The sealing hose 2 is made of a commonly used elastic sealing material for sealing components; the specific existing sealing material used will not be listed here, as long as it basically has the function of elastic waterproof sealing. The sealing hose 2 has good flexibility and elasticity, which can tightly wrap the wire 5, fill the gap between the outer shell 3 and the wire 5, and prevent external impurities from entering the sealed structure. At the same time, the sealing hose 2 provides a certain degree of protection for the wire 5, preventing the wire from being damaged by friction and collision.

[0031] Specifically, one end of the locking nut 1 is screwed onto the guide tube 31, and the internal thread of the locking nut 1 is located in the middle of the inner hole of the locking nut 1, which is more conducive to the alignment and screwing of the locking nut 1 and the guide tube 31. The other end of the locking nut 1 has an annular platform inside, and the port 21 of the sealing hose 2 passes through the annular platform. In this embodiment, the port 21 at least partially passes through the locking nut 1, further improving the precise connection between the locking nut 1 and the sealing hose 2, and enhancing dustproof and waterproof performance. Furthermore, the locking nut 1 is used to firmly connect the sealing hose 2 to the outer shell 3 of the equipment. The contact surface has threads, and by rotating and tightening, axial pressure is generated to ensure that the sealing part will not loosen due to vibration, external pulling, or other factors, thus playing a role in displacement, sealing, and fastening. Example 3

[0032] Based on Embodiment 1 or Embodiment 2, the outer casing 3 houses a fixing ring 4 for fixing the wire 5. The fixing ring 4 is located in the inner cavity 32, and its outer diameter is larger than the diameter of the guide tube 3 of the outer casing 3. Further, the fixing ring 4 is a metal ring capable of being fixedly fitted or pressed onto the wire 5. However, it is not limited to this and other rigid materials can also be used. In this embodiment, the fixing ring 4 is an iron ring. The iron ring serves to fix the wire 5 in the sealing structure. The iron ring has an open design, and its outer diameter is larger than the inner diameter of the wire hole in the outer casing 3. When the iron ring is clamped in a suitable position on the wire 5, and an external force pulls on the wire 5, the iron ring gradually approaches the wire hole in the outer casing as the wire 5 moves. Because the outer diameter of the iron ring is larger than the inner diameter of the wire hole in the outer casing 3, when it reaches the port of the outer casing 3, it will be blocked by the outer casing 3, preventing the wire 5 from moving further outward and avoiding damage to the wire 5 due to excessive pulling.

[0033] Working principle:

[0034] This utility model is a structurally stable and easily detachable wire sealing structure that effectively prevents external impurities from entering the lead-out device of the wire 5, thus improving the safety and reliability of the wire 5. Through the coordinated operation of the locking nut 1, sealing hose 2, outer shell 3, and fixing ring 4, reliable sealing and protection of the wire 5 are achieved. It effectively prevents external moisture, dust, and other impurities from entering the lead-out device of the wire 5, avoiding short circuits, leakage, and other faults caused by moisture or corrosion, thereby improving the safety and reliability of the wire 5. The sealing structure also has protective capabilities, protecting the wire 5 from external mechanical damage and extending its service life.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
