Description

Technical Field

[0001] This utility model relates to the field of Teflon tube technology, and in particular to a Teflon tube that is easy to connect. Background Technology

[0002] Teflon pipe, also known as polytetrafluoroethylene (PTFE) pipe, is a high-performance pipe made of fluoropolymer material. It has chemical stability and can withstand the effects of strong acids, strong alkalis, strong oxidants, reducing agents and various organic solvents.

[0003] For example, Chinese patent CN216045919U discloses a convenient Teflon tube, including a Teflon tube, a connector, a groove, a pad, and a protective wrapping device. The connector is fixedly installed at both ends of the Teflon tube, the groove is formed on the surface of the connector, the pad is fitted on the surface of the connector, a connecting cylinder is fixedly installed on one side of the connector, the surface of the connecting cylinder has external threads, a fastening cylinder is fitted on the surface of the connecting cylinder, the inside of the fastening cylinder has internal threads, and the surface of the Teflon tube is provided with a protective wrapping device.

[0004] In the aforementioned patent, although the problem of not being able to connect and disassemble the connector without a corresponding wrench is solved by using connectors and pads, the Teflon tube has relatively poor pressure resistance and the outer wrapping ring is also a single structure, which cannot withstand excessive pressure. It is only suitable for the transportation of low-pressure fluids. When the fluid pressure is too high, it is easy to cause damage to the tube body. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing Teflon tubes, such as relatively poor pressure resistance, a single outer ring structure that cannot withstand excessive pressure, and suitability only for transporting low-pressure fluids. When the fluid pressure is too high, the tube body is easily damaged. Therefore, this invention proposes a Teflon tube with convenient connection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a conveniently connected Teflon tube, comprising a Teflon tube body, a pressure-resistant auxiliary mechanism provided on the outer ring surface of the Teflon tube body, the pressure-resistant auxiliary mechanism comprising a reinforcing ring, a supporting tube, and a buffer component one, a sleeve fixedly connected to the inner ring surface of the reinforcing ring, an inner strip engaged on the inner ring surface of the sleeve, one side of the inner strip fixedly connected to the outer ring surface of the supporting tube, and the outer ring surface of the supporting tube and the inner ring surface of the sleeve being compositely connected, the inner ring surface of the supporting tube being fixedly connected to the buffer component one, a reinforcing tube fixedly connected to one side of the buffer component one, the inner ring surface of the reinforcing tube being fixedly connected to the Teflon tube body, and a buffer component two installed between the supporting tube and the reinforcing tube.

[0007] Preferably, the longitudinal section of the second buffer component is arc-shaped, one end of the second buffer component is fixedly connected to the inner annular surface of the support tube, and the other side of the second buffer component overlaps with the reinforcing tube.

[0008] Preferably, a limiting block is fixedly connected to the outer annular surface of the sleeve, and a guide strip is inserted through the limiting block. The guide strip and the limiting block are connected by bolts via threads.

[0009] Preferably, the guide strip and the limiting block are slidably connected, and one end of the guide strip is fixedly connected to a connector, with one side of the connector overlapping the end of the sleeve.

[0010] Preferably, a connector is fixedly connected to the inner wall of the connector, one end of which is inserted into the Teflon tube body, and a through hole is opened on one side of the connector.

[0011] Preferably, an extension tube is fixedly connected to one side of the connector, and a sealing ring one and a sealing ring two are fixedly connected to the inner circumferential surface of the extension tube, with one side of the sealing ring two overlapping with the connector.

[0012] Preferably, the outer ring surface of the extension tube is threaded, and a fixing ring is overlapped on the outer ring surface of the extension tube. The two ends of the fixing ring are connected to locking bolts by threads.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the inner annular surface of the reinforcing ring is fixedly connected to the sleeve, and the two sides of the buffer component one are fixedly connected to the support pipe and the reinforcing pipe respectively. When the fluid pressure inside the pipe is too high, the buffer component one and the buffer component two are compressed between the support pipe and the reinforcing pipe to achieve buffering on one side of the support pipe. The reinforcing pipe wraps around the Teflon tube body, which can reduce the damage to the Teflon tube body after impact, thereby ensuring the normal use of the entire tube body.

[0015] 2. In this utility model, the guide strip is slidably connected to the limiting block, and the fixing ring and the locking bolt are connected by threads. The guide strip is inserted into the limiting block, and the guide strip is moved along the limiting block so that one side of the connector overlaps with the sleeve. This allows the connector and the extension tube to be installed at one end of the sleeve. The connector and the extension tube facilitate the connection between the Teflon tube body and the external components. Moreover, the sealing ring one and the sealing ring two can provide double sealing for the inside of the extension tube, increasing the sealing performance of the extension tube connection and reducing leakage during liquid flow.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: Refer to Figures 1-4 As shown: A conveniently connected Teflon tube includes a Teflon tube body 12. A pressure-resistant auxiliary mechanism is provided on the outer ring surface of the Teflon tube body 12. The pressure-resistant auxiliary mechanism includes a reinforcing ring 10, a support tube 13, and a buffer element 15. A sleeve 1 is fixedly connected to the inner ring surface of the reinforcing ring 10. An inner strip 11 is engaged with the inner ring surface of the sleeve 1. One side of the inner strip 11 is fixedly connected to the outer ring surface of the support tube 13, and the outer ring surface of the support tube 13 is compositely connected to the inner ring surface of the sleeve 1. The inner ring surface of the support tube 13 is fixedly connected to the buffer element 15. A reinforcing tube 14 is fixedly connected to one side of the buffer element 15. The inner ring surface of the reinforcing tube 14 is fixedly connected to the Teflon tube body 12. A second buffer element 16 is installed between the support tube 13 and the reinforcing tube 14. The second buffer element 16 has an arc-shaped longitudinal section. One end of the second buffer element 16 is fixedly connected to the inner ring surface of the support tube 13, and the other side of the second buffer element 16 overlaps with the reinforcing tube 14.

[0024] The reinforcing ring 10 provides external support and protection for the sleeve 1, reducing the contact area between the outer ring surface of the sleeve 1 and the ground or other structures, thereby reducing wear during use. The built-in strip 11 increases the contact area between the support pipe 13 and the sleeve 1, achieving a tight connection between the sleeve 1 and the support pipe 13. The buffer element 15 and the buffer element 2 16 connect the support pipe 13 and the reinforcing pipe 14, providing buffer protection for the support pipe 13 and the reinforcing pipe 14. By wrapping the Teflon pipe body 12 with the reinforcing pipe 14, the reinforcing pipe 14 and the buffer element 2 16 can be stably installed and used outside the Teflon pipe body 12. The double buffering of the buffer element 15 and the buffer element 2 16 reduces damage to the Teflon pipe body 12 during use, thus ensuring the normal use of the entire pipeline.

[0025] Example 2: Figure 1 and Figure 2 As shown, a limiting block 5 is fixedly connected to the outer ring surface of the sleeve 1. A guide strip 4 is inserted through the limiting block 5. The guide strip 4 and the limiting block 5 are connected by bolts through threads. The guide strip 4 and the limiting block 5 are slidably connected. A connector 2 is fixedly connected to one end of the guide strip 4. One side of the connector 2 overlaps with the end of the sleeve 1. A connector 9 is fixedly connected to the inner wall of the connector 2. One end of the connector 9 is inserted into the Teflon tube body 12. A through hole is opened on one side of the connector 9. An extension tube 3 is fixedly connected to one side of the connector 2. A sealing ring 7 and a sealing ring 8 are fixedly connected to the inner ring surface of the extension tube 3. One side of the sealing ring 8 overlaps with the connector 9. A thread is opened on the outer ring surface of the extension tube 3. A fixing ring 6 overlaps on the outer ring surface of the extension tube 3. Locking bolts 17 are connected to both ends of the fixing ring 6 through threads.

[0026] The limiting block 5 guides the installation of the guide strip 4, allowing one side of the connector 2 to overlap with the sleeve 1. The threaded connection limits the insertion position of the guide strip 4 inside the limiting block 5, thus limiting the connector 2 and reducing loosening during use. The connector 9 and the extension tube 3 guide the flow of liquid. The sealing ring 7 and the sealing ring 8 improve the sealing performance of the extension tube 3 connection. The locking bolt 17 tightens both ends of the fixing ring 6. The fixing ring 6 reinforces the connection between the external connection structure and the extension tube 3, reducing loosening of the connection structure.

[0027] The usage and working principle of this device are as follows: First, when the entire pipe needs to be connected, the connecting component is threaded to the extension pipe 3 until one end of the connecting component overlaps with one side of the connector 2. Then, the locking bolt 17 is rotated, and the connecting component is tightened by the fixing ring 6 to achieve a stable connection between the extension pipe 3 and the connecting component. The liquid enters the extension pipe 3 through the external component, and then enters the connector 9 and the Teflon tube body 12 through the extension pipe 3. When the entire pipe is subjected to external pressure, the rubber reinforcing ring 10 provides initial buffering. The sleeve 1 and the support pipe 13 apply force to the buffer component 15 and the buffer component 16. The buffer component 15 and the buffer component 16 buffer one side of the reinforcing pipe 14, reducing the damage to the reinforcing pipe 14 and the Teflon tube body 12. When the fluid pressure inside the pipe is too high, the buffer component 15 and the buffer component 16 are compressed between the support pipe 13 and the reinforcing pipe 14 to achieve buffer protection for the Teflon tube body 12.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
