[0026] The following is combined with Figure 1-Figure 2 The present application is further described with specific embodiments:

[0028] like Figure 1 to Figure 2 As shown, an expansion waterproof wiring device includes: a main body 2, a wiring joint 3, two flexible parts 4, and two bolts 5, wherein the main body 2 has at least one channel 21 arranged along the length direction of the main body 2; the wiring joint 3 is arranged in the middle of the channel 21, and the wiring joint 3 has a first threading channel 31; the flexible part 4 is arranged in both ends of the channel 21 and abuts on the wiring joint 3, and the wiring joint 3 is located between the two flexible parts 4; the flexible part 4 has a second threading channel 41 that can be connected to the first threading channel 31; the two bolts 5 are respectively threadedly connected to the two ends of the channel 21, and the bolts 5 have a third threading channel 51 that penetrates along the axial direction thereof; wherein the flexible part 4 can be compressed and expanded under the squeezing of the bolts 5, so that the outer wall of the flexible part 4 abuts and seals against the inner wall of the channel 21, and the inner wall of the flexible part 4 abuts and seals against the cable.
[0029] In the present application, when cable wiring is required, the cable is passed through the third threading channel 51 of the bolt 5, the second threading channel 41 of the flexible member 4 and the first threading channel 31 of the wiring connector 3 in sequence, so that the wiring part is in the wiring connector 3, and then the bolts 5 at both ends of the channel 21 are tightened. The bolts 5 will squeeze the flexible member 4 during the screwing process, and the flexible member 4 will compress and expand under the squeezing of the bolts 5. The outer wall of the flexible member 4 is tightly against the inner wall of the channel 21 to form a seal. At the same time, the inner wall of the flexible member 4 is also tightly against the cable to form a seal, thereby achieving sealing and waterproofing of the cable wiring.
[0030] The flexible member 4 is squeezed by the bolt 5 so that the flexible member 4 is tightly against the inner wall of the channel 21 and the cable, which can effectively prevent water and other liquids from entering the interior of the wiring device and ensure the sealing of the wiring. This connection method can achieve a seal of 260 kg of air pressure without leakage. The device has a simple structure. During the installation process, it only needs to pass the cable through each channel 21 and tighten the bolt 5. The operation is convenient and quick. Due to the use of compression and expansion sealing, even in harsh environments, such as humidity, high temperature, acid and alkali conditions, it can maintain good sealing performance and improve the reliability of the wiring device.
[0031] Furthermore, the total length of the rods of the two flexible members 4 , the wiring connector 3 , and the bolt 5 is greater than the length of the channel 21 .
[0032] Specifically, the main body 2 is semicircular, and the inner wall of the main body 2 has a semicircular groove.
[0033] The semicircular groove can adapt to the shape of the oil pipe and is easy to install.
[0034] Specifically, the main body 2 is provided with three channels 21 .
[0035] Providing three channels 21 means that there are more reserved holes available. This provides great flexibility for connecting different numbers of cables. In practical applications, there may be a situation where multiple cables need to be connected. Three channels 21 can meet this demand and avoid the trouble of installing additional wiring devices due to insufficient holes.
[0036] Specifically, the flexible member 4 and the channel 21 are tightly matched.
[0037] The tight fit makes it difficult for the flexible member 4 to be displaced or loosened in the channel 21. Even under external vibration, impact or the tension of the cable itself, the flexible member 4 can always remain in a fixed position to ensure the durability of the sealing effect, which improves the stability of the entire wiring device and reduces the risk of failure caused by looseness.
[0038] Specifically, both ends of the channel 21 are provided with internal threads adapted to the bolts 5 , and a smooth inner wall of the channel 21 is provided between the two internal threads.
[0039] The internal thread of the adapter bolt 5 is provided so that the bolt 5 can be easily screwed into the two ends of the channel 21 to achieve the extrusion seal of the flexible member 4. This design facilitates the installation process, and the operator can quickly and accurately install the bolt 5 in place, thereby improving the work efficiency. The internal thread and the bolt 5 are tightly matched, which can ensure that the bolt 5 will not loosen during use, thereby ensuring the reliability of the seal.
[0040] After the flexible member 4 expands, it can better form a seal with the smooth inner wall.
[0041] Specifically, the flexible member 4 is made of rubber material.
[0042] Rubber has excellent elasticity and can be compressed and expanded under the extrusion of the bolt 5, tightly fitting the inner wall of the channel 21 and the cable to form a good seal. The elasticity of the rubber enables the flexible part 4 to adapt to cables of different sizes, ensuring the reliability of the seal. Even when the temperature changes or is subjected to a certain pressure, the rubber flexible part 4 can maintain good sealing performance. Rubber has good resistance to corrosive substances such as acids, alkalis, and oils.
[0043] Specifically, a tapered guide portion 42 is provided at the end of the flexible member 4 .
[0044] The unique shape of the tapered guide portion 42 allows the cross-sectional area of the front end of the flexible member 4 to gradually decrease when the flexible member 4 is inserted into the channel 21. As a result, the contact area with the inner wall of the channel 21 is also reduced accordingly during the insertion process, thereby greatly reducing the installation resistance. The operator can push the flexible member 4 into the channel 21 more easily, reducing the effort and time required for installation.
[0045] It should be noted that the above embodiments are only used to illustrate the present application and are not intended to limit the technical solutions described in the present application. Although the present application has been described in detail in this specification with reference to the above embodiments, a person of ordinary skill in the art should understand that a person of ordinary skill in the art can still modify or make equivalent substitutions to the present application, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present application should be included in the scope of the claims of the present application.
