Abstract
Description
Technical Field
[0001] This utility model relates to the field of PVC pipe processing technology, specifically a PVC pipe connection device. Background Technology
[0002] PVC pipes are widely used in many fields such as construction, municipal engineering, and chemical industry due to their advantages such as strong corrosion resistance, low cost, and convenient installation. In the actual laying and installation of PVC pipes, the connection between pipes is a critical step, as the quality of the connection directly affects the stability, sealing, and service life of the entire pipeline system.
[0003] Currently, the most common methods for connecting PVC pipes are heat fusion and adhesive bonding. Both methods require a connecting device to secure the PVC pipes. During operation, the PVC pipes are first installed on the connecting device, then both ends of the pipes are treated accordingly, such as softening the pipe ends through heat fusion or evenly applying adhesive. Finally, the two pipes are aligned to the same horizontal plane for connection.
[0004] However, currently, the pipe connection process mainly relies on manual pressure application. Manual pressure application makes it difficult to ensure that the applied pressure is consistent and evenly distributed across the pipe connection area each time. Uneven pressure can lead to gaps, misalignment, and other problems at the pipe connection point. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a PVC pipe splicing device that solves the problem of uneven manual force application during the traditional PVC pipe splicing process.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution: a PVC pipe docking device, comprising a base, on which two support rods are arranged side by side with a gap, each support rod being fitted with a sleeve for supporting the pipe body, a limiting block one being provided at the end of each support rod, a connecting member movable along the sleeve axis being installed inside the sleeve, a limiting block two being provided at one end of the connecting member, a spring being installed between the limiting block one and the limiting block two, and a push plate being installed at the other end of the connecting member, the spring providing elastic force to the push plate, the push plate applying pressure to one end of the pipe body, thereby docking the two pipe bodies together.
[0009] Furthermore, a baffle is rotatably installed in the middle of the support rod to block the end of the pipe body that is connected to it.
[0010] Furthermore, the support block is provided with a mounting groove for installing a baffle.
[0011] Furthermore, the sleeves are installed on both sides of the support rod, and there is a gap between the two sleeves on the same support rod.
[0012] Furthermore, the base is provided with a support block for supporting the support rod.
[0013] Furthermore, a handle is provided on the outer side of the push plate.
[0014] Furthermore, a protective pad is provided on the inner side of the push plate.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a PVC pipe connection device, which has the following advantages:
[0017] This PVC pipe joining device, by incorporating a connector within a sleeve, utilizes the elastic potential energy of a spring to continuously provide a stable and uniform pushing force to a push plate, thus overcoming the uneven force distribution caused by manual pressure application in the past. During pipe joining, the push plate evenly transmits the spring's pushing force to the pipe ends, ensuring uniform force distribution on both pipe joining ends. This effectively avoids problems such as joint gaps and misalignment caused by uneven force distribution, greatly improving the accuracy and reliability of pipe joining and ensuring the sealing and stability of the entire pipeline system.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model discloses a PVC pipe connection device, including a base 1. Two support rods 2 are arranged side-by-side with a gap on the base 1. Each support rod 2 is fitted with a sleeve 3 for supporting the pipe body 4. There can be one or two sleeves 3. If two sleeves 3 are installed on both sides of the support rod 2, there is a gap between the two sleeves 3 on the same support rod 2. A support block 8 is provided on the base 1 for supporting the support rods 2.
[0025] A baffle 9 is rotatably mounted in the middle of the support rod to block and limit the connection of the pipe body 4 to the connecting end. The baffle 9 is then moved away during connection. The support block 8 has a mounting groove 13 for installing the baffle 9.
[0026] The end of the support rod 2 is provided with a limiting block 5. The sleeve 3 is equipped with a connector 6 that can move along the axis of the sleeve 3. One end of the connector 6 is provided with a limiting block 12. A spring 11 is installed between the limiting block 5 and the limiting block 12. The other end of the connector 6 is equipped with a push plate 7. The elastic potential energy of the spring 11 provides elastic force to the push plate 7. The push plate 7 applies pressure to one end of the pipe body 4, so that the two sides of the pipe body 4 are connected.
