Description

Technical Field

[0001] This utility model relates to the field of power pipe connection technology, and in particular to an MPP power pipe connector. Background Technology

[0002] MPP pipes use modified polypropylene as the main raw material, and are characterized by high temperature resistance and external pressure resistance. They are suitable for medium and low voltage power transmission cable ducts below 10KV. During production, they are manufactured in a certain length to ensure transportation needs. However, during construction, multiple pipes are usually connected to ensure construction needs.

[0003] The following problems exist in the connection of existing power pipes: 1. Existing power pipe connections are usually achieved through connectors. Most connectors are fixed by directly squeezing the outside of the connection between two MPP power pipes. This fixing method is cumbersome and can easily cause the MPP power pipes to break; 2. Existing connectors do not have high sealing performance during connection, which can easily cause the cable inside the pipe to get damp or be eaten by insects.

[0004] To solve the above problems, a new type of MPP power pipe connector is needed. Summary of the Invention

[0005] The purpose of this invention is to provide an MPP power pipe connector that enables rapid connection of power pipes and provides high sealing performance.

[0006] To achieve the above objectives, this utility model provides an MPP power pipe connector, comprising an outer cylinder and an inner cylinder. The middle section of the inner sidewall of the outer cylinder is fixedly connected to the outer sidewall of the inner cylinder. Fixing members are connected to both ends of the outer sidewall of the outer cylinder. Slots and positioning posts are provided on both ends of the inner cylinder. The central axis of the slot coincides with the central axis of the inner cylinder. The slot is adapted to the connector structure at the end of the MPP power pipe. The minimum distance from the positioning post to the central axis of the inner cylinder is greater than the outer radius of the slot. The positioning post is adapted to the positioning insertion hole structure at the end of the MPP power pipe. A threaded slot is provided on the outer sidewall of the MPP power pipe, which is adapted to the fixing member structure.

[0007] Preferably, the inner cylinder is made of rubber.

[0008] Preferably, the outer cylinder is made of MPP.

[0009] Preferably, the fastener is a bolt.

[0010] Preferably, the inner cylinder is bonded to the outer cylinder.

[0011] Preferably, the inner wall of the outer cylinder is provided with two limiting bosses integrally connected thereto. The two limiting bosses are respectively located at both ends of the inner cylinder and abut against the inner cylinder. The inner radius of the limiting bosses is greater than the maximum distance from the positioning post to the central axis of the inner cylinder.

[0012] Therefore, the MPP power pipe connector with the above-described structure of this utility model has the following beneficial effects:

[0013] 1. Ensure the airtight connection of the two MPP power pipes by inserting the connector at the end of the MPP power pipe into the slot on the inner cylinder.

[0014] 2. By inserting the positioning pin into the positioning hole, the fastener and the threaded slot can be quickly aligned, making it convenient to use the fastener to quickly connect the connector and the MPP power pipe, thereby achieving a quick connection between the two power pipes.

[0015] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] like Figure 1-2 As shown, an MPP power pipe connector includes an outer cylinder 1 and an inner cylinder 2. The outer cylinder is made of MPP, which has high strength and resistance to external pressure. The middle section of the inner wall of the outer cylinder 1 is fixedly connected to the outer wall of the inner cylinder 2. In this embodiment, the inner cylinder 2 is bonded to the outer cylinder 1.

[0024] The outer cylinder 1 has fasteners 3 connected to both ends of its outer side wall; these fasteners 3 can be bolts. The inner cylinder 2 has slots 4 and positioning pins 5 on both ends. The central axis of the slots 4 coincides with the central axis of the inner cylinder 2, and the minimum distance from the positioning pin 5 to the central axis of the inner cylinder 2 is greater than the outer radius of the slots 4. The slots 4 are adapted to the connector 6 at the end of the MPP power pipe 10, and are used to insert the connector 6 into the end of the MPP power pipe 10, thus ensuring the sealing performance of the MPP power pipe 10 connection. The inner cylinder 2 is made of rubber; the deformation characteristics of rubber further enhance the sealing performance of the MPP power pipe 10 connection. Additionally, rubber provides a certain buffering function when the MPP power pipe 10 and connector are subjected to external forces. The positioning pins 5 are adapted to the positioning holes 7 at the end of the MPP power pipe 10, and are used to insert into the positioning holes 7. The outer side wall of the MPP power pipe 10 has threaded slots 8 adapted to the structure of the fasteners 3.

[0025] In use, the connector 6 at the end of the MPP power pipe 10 is inserted into the slot 4, and the positioning pin 5 is inserted into the positioning hole 7. The fixing part 3 is then aligned with the threaded slot 8. This allows for quick connection between the connector and the MPP power pipe 10 using the fixing part 3. After connection, the fixing part 3, the positioning pin 5, and the positioning hole 7 together ensure the stability of the connection between the connector and the MPP power pipe 10. The slot 4 ensures the sealing of the connection between the connector and the MPP power pipe 10.

[0026] Example 2

[0027] The difference between this embodiment and Embodiment 1 lies in the connection method between the inner cylinder 2 and the outer cylinder 1: as follows Figure 3 As shown, the inner wall of the outer cylinder 1 is provided with two integrally connected limiting bosses 9. The two limiting bosses 9 are located at both ends of the inner cylinder 2 and abut against the inner cylinder 2. The inner radius of the limiting bosses 9 is greater than the maximum distance from the positioning post 5 to the central axis of the inner cylinder 2. The limiting bosses 9 can ensure the stability of the connection between the inner cylinder 2 and the outer cylinder 1, and facilitate the disassembly and assembly of the inner cylinder 2.

[0028] Therefore, the MPP power pipe connector of this utility model with the above structure can realize the rapid connection of power pipes and has high sealing performance.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
