Description

Technical Field

[0001] This utility model relates to the field of composite pipe technology, and in particular to a polytetrafluoroethylene composite pipe connection structure. Background Technology

[0002] Polytetrafluoroethylene (PTFE), also known as Teflon, is a high-molecular polymer made by polymerizing tetrafluoroethylene as a monomer. Its chemical formula is (C₂F₄)n. It exhibits excellent heat and cold resistance and can be used continuously at temperatures ranging from -180 to 260°C. This material is resistant to acids, alkalis, and various organic solvents, and is virtually insoluble in all solvents. Furthermore, PTFE is heat-resistant and has an extremely low coefficient of friction, making it suitable for lubrication and as an ideal coating for easy-to-clean water pipe interiors.

[0003] Most PTFE composite pipes are segmented, requiring a composite pipe connection structure for splicing during use. Existing composite pipe connection structures have low strength at the joints after installation and are prone to breakage. Therefore, we propose a PTFE composite pipe connection structure.

A support plate is provided on the connecting pipe between the two mating plates. Multiple uniformly distributed reinforcing plates are provided on the outer wall of the connecting pipe between the support plate and the mating plates. A connecting plate is provided on the outer wall of the mating plate, and an opening groove is provided on the connecting plate for the arc-shaped plates to engage.

[0023] Example

[0024] refer to Figures 1-6 A polytetrafluoroethylene (PTFE) composite pipe connection structure includes a composite pipe body 1 and a connecting assembly 2 disposed at the connection point of two adjacent composite pipe bodies 1. Two opposing arc-shaped plates 101 are provided at the ends of the composite pipe bodies 1. The connecting assembly 2 includes a connecting pipe 201 sleeved on the outer sides of the ends of the two adjacent composite pipe bodies 1. Both ends of the connecting pipe 201 are provided with mating plates 203. A support plate 202 is provided on the connecting pipe 201 between the two mating plates 203. Multiple uniformly distributed reinforcing plates 204 are provided on the outer wall of the connecting pipe 201 between the support plate 202 and the mating plate 203. The reinforcing plates 204 are symmetrically arranged on the left and right sides of the support plate 202, and the reinforcing plates 204 on each side of the support plate 202 are evenly distributed around the outer side wall of the connecting pipe 201, so that the connection between the two adjacent composite pipe bodies 1 can be balanced and stable. The reinforcing plates 204 are triangular in structure. Since triangles have stability, they have the characteristics of being stable, firm, and pressure resistant, which improves the overall strength of the connecting pipe 201 and further strengthens the strength of the connection between the two adjacent composite pipe bodies 1. The outer side wall of the mating plate 203 is provided with a connecting plate 205, and the connecting plate 205 is provided with an opening groove 206 that allows the arc plate 101 to be snapped in.

[0025] Furthermore, the inner sidewall of the connecting plate 205 is provided with an installation groove 207 that allows the arc plate 101 to be snapped into the opening groove 206 and then rotated into place. By rotating the connecting component 2, the arc plate 101 is inserted into the installation groove 207 of the connecting plate 205, thereby achieving a preliminary fixed connection between the connecting component 2 and the two adjacent composite pipe bodies 1.

[0026] Furthermore, one end of the arc-shaped plate 101 is provided with a limiting block 103, and the connecting plate 205 is provided with a limiting groove 214 for the limiting block 103 to be inserted. Through the setting of the limiting groove 214 and the limiting block 103, the displacement of the connecting plate 205 can be limited, so that the first locking hole 212 of the connecting plate 205 is aligned and connected with the second locking hole 102 of the arc-shaped plate 101.

[0027] Furthermore, an anti-detachment plate 208 is provided on the outer side of the connecting plate 205, and a threaded rod 209 is screwed onto the anti-detachment plate 208. One end of the threaded rod 209 is provided with a locking rod 210, and the other end of the threaded rod 209 is provided with a drive handle 211.

[0028] Furthermore, each of the anti-detachment plates 208 on both sides of the threaded rod 209 is provided with a connecting rod 213. One end of the connecting rod 213 is fixedly connected to the connecting plate 205, and the other end of the connecting rod 213 is fixedly connected to the anti-detachment plate 208.

[0029] Furthermore, the connecting plate 205 is provided with a first locking hole 212 for the locking rod 210 to be inserted, and the arc plate 101 is provided with a second locking hole 102 for the locking rod 210 to be inserted. By rotating the drive handle 211, the threaded rod 209 is driven to rotate on the anti-detachment plate 208 to achieve displacement, and the locking rod 210 is driven to be inserted into the second locking hole 102 of the arc plate 101, thereby locking the arc plate 101 in the mounting groove 207 of the connecting plate 205, and then fixing the connecting assembly 2 at the connection port of the two composite pipe bodies 1.

[0030] In the initial state, the front end of the locking rod 210 is retracted into the first locking hole 212 of the connecting plate 205, so as not to affect the insertion of the arc plate 101 into the mounting groove 207 of the connecting plate 205.

[0031] The working principle of this utility model:

[0032] During installation, firstly, align the opening slot 206 of the connecting component 2 with the arc plate 101 of the composite pipe body 1 and insert it, so that the connecting pipe 201 of the connecting component 2 is fitted and installed at the port of the two adjacent composite pipe bodies 1. At this time, the arc plate 101 is in contact with the mating plate 203. Then, rotate the connecting component 2 so that the arc plate 101 is inserted into the mounting slot 207 of the connecting plate 205. The displacement of the rotating connecting plate 205 is limited by the limiting block 103, so that the first locking hole 212 of the connecting plate 205 is aligned and connected with the second locking hole 102 of the arc plate 101. Then, rotate the drive handle 211. The drive handle 211 drives the threaded rod 209 to rotate on the anti-detachment plate 208 to achieve displacement, and drives the locking rod 210 to be inserted into the second locking hole 102 of the arc plate 101, thereby locking the arc plate 101 in the mounting slot 207 of the connecting plate 205, and then fixing the connecting component 2 at the connection port of the two composite pipe bodies 1.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
