Description

Technical Field

[0001] This utility model relates to the field of PVC pipe sealing technology, and in particular to a PVC pipe insertion sealing structure. Background Technology

[0002] In pipeline engineering, PVC pipes are widely used due to their advantages such as light weight, corrosion resistance, and low price. However, the connection of PVC pipes has always been a major challenge for engineers. Traditional PVC pipe connection methods, such as adhesive bonding and heat fusion, can meet the connection requirements to a certain extent, but they have many shortcomings. For example, adhesive bonding is easily affected by environmental humidity and temperature, leading to unstable connection strength; heat fusion requires specialized equipment and skills, and is complex and costly to operate.

[0003] To address these issues, people began experimenting with plug-in sealing structures to connect PVC pipes. Plug-in sealing structures, through well-designed connection and sealing components, achieve quick and secure connections between PVC pipes while ensuring good sealing performance. However, existing plug-in sealing structures still have some problems in practical applications.

[0004] First, some plug-in sealing structures have poorly designed connection components, resulting in insufficient connection strength and making them prone to loosening or breakage under stress. This not only affects the normal use of the pipeline but may also create safety hazards.

[0005] Secondly, the sealing performance of sealing components is unstable. Due to limitations in sealing materials and structures, some plug-in sealing structures may fail after prolonged use, leading to liquid or gas leaks. This not only wastes resources but may also pollute the environment. Utility Model Content

[0006] The purpose of this utility model is to provide a PVC pipe insertion sealing structure to solve the problems mentioned in the background art and facilitate its promotion.

[0007] A PVC pipe insertion sealing structure includes a connecting sleeve, on which a connecting component one and a connecting component two are symmetrically arranged, and on the connecting component one and the connecting component two are a sealing component. A fixing component is provided on the outer wall of the connecting sleeve, and a fixing auxiliary component is provided on the connecting component one and the connecting component two.

[0008] The connecting component includes an internal thread formed on the inner wall of the connecting sleeve and a connecting tube provided at one end of the connecting sleeve. The connecting tube has a connecting thread at the end near the connecting sleeve, and the connecting thread is threadedly connected to the internal thread.

[0009] Furthermore, the sealing assembly includes sealing grooves formed at both ends of the connecting sleeve and a sealing connecting plate fixedly disposed on the connecting pipe. The sealing connecting plate has a sealing block on the side near the connecting sleeve, and the sealing block is inserted into the sealing groove.

[0010] Furthermore, the fixing component includes a plurality of evenly arranged fixing connecting blocks fixedly disposed on the outer wall of the connecting sleeve, and fixing threaded rod one and fixing threaded rod two are symmetrically disposed on both sides of the fixing connecting blocks.

[0011] Furthermore, the fixing auxiliary component includes an auxiliary connecting sleeve sleeved on the outer wall of the connecting pipe. An auxiliary block corresponding to the fixing connecting block is fixedly provided on the outer wall of the auxiliary connecting sleeve. A fixing through hole is provided on the auxiliary block. The fixing through hole is inserted into the fixing threaded rod one and the fixing threaded rod two. The fixing threaded rod one and the fixing threaded rod two are threadedly connected to the fixing nut through the fixing through hole.

[0012] Furthermore, the structures of connection component one and connection component two are identical.

[0013] As an improvement, the beneficial effects of this utility model are as follows:

[0014] This utility model discloses a PVC pipe insertion sealing structure that achieves a secure connection between PVC pipes through connecting components. Connecting component one and connecting component two utilize the tight fit between the internal and external threads to ensure the strength and stability of the connection. This threaded connection method not only effectively resists external forces, preventing loosening or breakage of the connection, but also significantly improves the overall safety of the pipeline system. The innovative design of the sealing components significantly enhances sealing performance. The combined use of the sealing groove and sealing block forms a tight and durable sealing structure, effectively preventing liquid or gas leakage. The fixing component and fixing auxiliary component together simplify the PVC pipe installation process.

It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Identical components are indicated by the same reference numerals.

[0024] This embodiment provides a PVC pipe insertion sealing structure, including a connecting sleeve 1. The connecting sleeve 1 is symmetrically provided with a connecting component 2 and a connecting component 3. The connecting component 2 and the connecting component 3 are provided with a sealing component 4. The outer wall of the connecting sleeve 1 is provided with a fixing component 5. The connecting component 2 and the connecting component 3 are provided with a fixing auxiliary component 6. The connecting component 2 and the connecting component 3 have the same structure.

[0025] In this embodiment, connecting component 2 (and connecting component 3; since their structures are identical, connecting component 2 will be used as an example for the following description) includes an internal connecting thread 201 and a connecting pipe 202. The internal connecting thread 201 is formed on the inner wall of the connecting sleeve 1 and is used for threaded connection with the external thread of the PVC pipe. The connecting pipe 202 is located at one end of the connecting sleeve 1, and a connecting thread 203 is formed at the end closest to the connecting sleeve 1. This connecting thread 203 cooperates with the internal connecting thread 201 to realize the threaded connection between the connecting sleeve 1 and the connecting pipe 202. This design makes the connection between the connecting sleeve 1 and the connecting pipe 202 more secure and less prone to loosening.

[0026] In this embodiment, the sealing assembly 4 includes a sealing groove 401 and a sealing connecting plate 402. The sealing groove 401 is formed at both ends of the connecting sleeve 1 to accommodate the sealing block 403. The sealing connecting plate 402 is fixedly mounted on the connecting pipe 202, and the sealing block 403 is provided on the side of the connecting sleeve 1. When the connecting pipe 202 and the connecting sleeve 1 are connected by the connecting thread 203 and the connecting internal thread 201, the sealing block 403 is inserted into the sealing groove 401, thereby achieving a seal at the connection. This sealing method is simple and effective, and can prevent liquid or gas from leaking from the connection.

[0027] In this embodiment, the fixing component 5 includes a fixing connecting block 501, a fixing threaded rod one 502, and a fixing threaded rod two 503. The fixing connecting block 501 is fixedly disposed on the outer wall of the connecting sleeve 1, and multiple fixing connecting blocks 501 are evenly arranged to ensure the stability of the connection. The fixing threaded rod one 502 and the fixing threaded rod two 503 are symmetrically disposed on both sides of the fixing connecting block 501 for connecting with external structures. This design allows the connecting sleeve 1 to be firmly fixed in the required position and is not easy to shake.

[0028] In this embodiment, the fixing auxiliary component 6 includes an auxiliary connecting sleeve 601, an auxiliary block 602, and a fixing nut 604. The auxiliary connecting sleeve 601 is fitted onto the outer wall of the connecting pipe 202 to enhance the stability of the connecting pipe 202. The auxiliary block 602 is fixedly mounted on the outer wall of the auxiliary connecting sleeve 601 and corresponds to the fixing connecting block 501. The auxiliary block 602 has a fixing through hole 603, which can be inserted into the fixing threaded rod 1 502 and the fixing threaded rod 2 503. When the fixing through hole 603 is inserted into the fixing threaded rod 1 502 and the fixing threaded rod 2 503, the auxiliary connecting sleeve 601 (and the connecting pipe 202) can be firmly fixed to the connecting sleeve 1 by rotating the fixing nut 604. This design not only enhances the stability of the connection but also simplifies the installation process.

[0029] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
