Abstract

An electrical conduit structure for seismic expansion joints, belonging to the field of electrical wiring technology, is disclosed. It includes an outer fixing ring and two supporting legs. A conduit is threaded through the outer fixing ring. The inner end of each supporting leg is rotatably connected to the outer fixing ring, and the outer end is connected to a bearing seat mounted on the building wall via a supporting shaft. The supporting shaft is movably mounted on the bearing seat. An elastic arc plate is provided between the two supporting legs. In this invention, based on the connection structure between the outer fixing ring and the supporting legs, between the bearing seat and the supporting legs, and between the supporting legs, deformation of the outer fixing ring and conduit can be avoided by changing the angle between the supporting legs when the width of the seismic expansion joint changes. When the position of the seismic expansion joint changes, the change in the horizontal position between the supporting shaft and the bearing seat can offset the change in the position of the seismic expansion joint.

[0019] Please see Figure 1-3 :

[0020] Example 1

[0021] This utility model provides a technical solution: a seismic deformation joint building electrical pipeline structure, including: an outer fixing ring 2 and a supporting leg 6;

[0022] The outer fixing ring 2 is a hollow tubular tube with openings at the top and bottom. A conduit 3 is inserted inside the outer fixing ring 2. There are two support legs 6. One end of the two support legs 6 is rotatably connected to the outer wall of the outer fixing ring 2 via a rotating shaft. The other end of the support leg 6 is provided with a support shaft 7. A bearing seat 8 is installed at opposite positions on both sides inside the seismic deformation joint by screws. The support shaft 7 is inserted into the bearing seat 8.

[0023] The dimensions of structures such as the outer fixing ring 2 and the support leg 6 are set according to the size of the expansion joint formed between the two building walls.

[0024] When in use, the conduit 3 is inserted into the outer fixing ring 2. The inside of the conduit 3 is used for cable routing. When the seismic expansion joint contracts or expands, the support legs 6 on both sides push the outer fixing ring 2 forward or backward, so that the outer fixing ring 2 and the conduit 3 are away from or close to the seismic expansion joint, thus avoiding damage to the outer fixing ring 2 and the conduit 3 by the compression or stretching of the seismic expansion joint.

[0025] Both support legs 6 are provided with snap-fit ​​plates 11 on their side walls, and an elastic arc plate 10 is connected between the two snap-fit ​​plates 11.

[0026] The elastic arc plate 10 is made of spring steel. When the two support legs 6 come together or separate, the elastic arc plate 10 is compressed or stretched and deformed to generate elastic force. Under the elastic force of the elastic arc plate 10, it provides elastic support to the outer fixing ring 2 and the two support legs 6.

[0027] Example 2

[0028] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: an anti-slip pad 4 is provided on the inner wall of the outer fixing ring 2. The anti-slip pad 4 is made of rubber and is sleeved on the outer wall of the conduit 3. The rubber anti-slip pad 4 has the function of elastic deformation, which can buffer and support the conduit 3.

[0029] The outer wall of the outer fixing ring 2 is threaded with a fastening screw 5. The threaded end of the fastening screw 5 extends into the interior of the outer fixing ring 2. When the fastening screw 5 is tightened, it can support the anti-slip pad 4 and the outer wall of the conduit 3, thereby reinforcing the conduit 3 and preventing it from loosening.

[0030] Example 3

[0031] This utility model provides a technical solution based on Embodiment 1: the included angle between the two supporting legs 6 is 120°-180°.

[0032] Example 4

[0033] This utility model provides a technical solution based on Embodiment 1: the length of the support shaft 7 is greater than the length of the bearing seat 8, and the support shaft 7 can move left and right within the bearing seat 8.

[0034] An anti-detachment baffle 9 is provided at the outer end of the support shaft 7. The cross-sectional area of ​​the anti-detachment baffle 9 is larger than that of the support shaft 7, which can prevent the support shaft 7 from detaching from the shaft seat 8.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
