[0002] As housing transactions gradually enter the stock era, the renovation volume of stock houses has been increasing year by year. At present, the concealed installation of electrical home decoration pipelines in old concrete houses requires re-grooving and burying pipes on the ground and walls for wiring. DN16 and DN20 electrical round pipes are usually used, and DN20 wire pipes are mostly used. Generally, the wall thickness of old houses is thin. The distance from the wall of the old concrete house to the exposed steel bar layer is only 1.5-3cm, and the distance between each steel bar is only 3cm. During the installation and grooving of the circular electrical pipe, the steel bars often need to be cut or removed to facilitate the grooving. However, the cutting or removal of the steel bars will affect the bearing capacity of the walls or floor slabs of the old house, causing certain safety hazards. Therefore, the development of an electrical pipe that passes through steel bars can effectively solve this problem and ensure the safety of living in old houses. Utility Model Content
[0003] In view of the above-mentioned problems, the utility model provides a round-to-square PVC electrical pipe suitable for crossing steel bars in old houses, which solves the safety problem caused by the risk of cutting steel bars when using round electrical pipes to dig grooves in old houses.

The size of the square pipe section is slightly larger than the size of the first socket and the second socket, so that the two ends can be plugged and fixed.
[0008] According to a further technical solution, the effective plug-in distance between the square electrical tube and the round-to-square electrical tube fitting is 1 cm.
[0009] According to a further technical solution, the outer diameter of the circular tube section is greater than the outer diameter of the square tube section.

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.
[0023] like Figure 1-Figure 4 As shown, a round-to-square PVC electrical pipe suitable for spanning steel bars in old houses comprises a square electrical pipe 1 and a round-to-square electrical pipe fitting 2. The two ends of the square electrical pipe 1 are respectively provided with a first socket 11 and a second socket 12. The round-to-square electrical pipe fitting 2 is respectively plugged and fixedly connected with the square electrical pipe 1 through the first socket 11 and the second socket 12. The square electrical pipe 1 comprises a first square body 3 and a second square body 4 that are slidably connected to each other.
[0024] picture Figure 5-Figure 6 As shown, the first square body 3 is a square opening structure, and a groove 31 is arranged on the inner wall of the first square body 3; the second square body 4 is a square opening structure corresponding to the first square body 3, and a convex strip 41 is arranged on the outer wall of the second square body 4, and the groove 31 and the convex strip 41 are slidably connected with each other.
[0025] like Figure 7 As shown, the round-to-square electrical pipe fitting 2 includes a round pipe section 21, a square pipe section 22, and a transition section 23 between the round pipe section 21 and the square pipe section 22. The square pipe section 22 is connected to the first receiving port 11 and the second receiving port 12 of the square electrical pipe 1. A long side plane of the square pipe section 22 is on the same plane as the bottom of the round pipe section 21.
[0026] The outer diameter of the circular tube section 21 is larger than the outer diameter of the square tube section 22 , and the size of the square tube section 22 is larger than the size of the square electrical tube 1 . During assembly, it is convenient for both ends of the square electrical tube 1 to be smoothly plugged and fixed inside the square tube section 22 .
[0027] Due to the internal curvature design of the round-to-square electrical pipe fitting 2, when the square electrical pipe 1 is inserted, there is an effective plug-in distance of 1 cm between the two.
[0028] During installation, the utility model round-to-square electrical pipe fitting 2 is matched with a DN20 round electrical pipe in front, the outer diameter of the round mouth is 22mm, the outer diameter of the square mouth is only 12mm, and the wall thickness is 1mm, which can match the extreme case of a wall of only 1.5cm, and leave a part of space for wall hanging and plastering. Compared with the round electrical pipe protruding outside the slot, the wall needs to be thickened, and the cost is reduced, highlighting its cost advantage;
[0029] When slotting and installing the assembled square electrical tube 1, the required length of the wire tube can be cut by the user according to the slot height, which can match the extreme situation of dense steel bars in old houses;
[0030] During the threading process, the required wires are placed in the second square body 4 of the square electrical tube 1. Since the wires are bent during the threading process, the assembled square electrical tube 1 is specially provided with a groove 31 and a convex strip 41 structure. The first square body 3 and the second square body 4 can be slidably matched and fixed, or directly buckled and fixed, so that multiple wires can be conveniently buckled and fixed. Even if the bending height of the wire exceeds the height of the square electrical tube 1, the groove 31 and the convex strip 41 can assist in fixing, or slide up and down to align;
[0031] The square electrical tube 1 and the round-to-square electrical tube fitting 2 of the utility model are both made of PVC; the edges of the square electrical tube 1 and the round-to-square electrical tube fitting 2 are chamfered to reduce resistance during installation and connection, and can reduce unnecessary damage to construction workers during installation compared to sharp right angles.
[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
