Technical Field

[0001] This utility model relates to the field of PE pipe installation technology, and in particular to a snap-fit ​​connection device for quick connection of PE pipes. Background Technology

[0002] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc. are all made of PE. HDPE is a highly crystalline, non-polar thermoplastic resin.

[0003] During transportation, PE pipes are connected to connectors using bolts. This connection method makes it very easy for the PE pipe and connector to break during transportation, which in turn affects the operation of the PE pipe. Utility Model Content

[0004] The purpose of this invention is to solve the problem of easy disconnection between the connecting pipe and the PE pipe in the prior art, and to propose a snap-fit ​​connection device for quick connection of PE pipe.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A snap-fit ​​connection device for quick connection of PE pipes includes a PE pipe and a connecting pipe. The connecting pipe includes a hollow positioning plate and a positioning post. The outer wall of the positioning post is provided with uniformly distributed limiting protrusions that move against the inner wall of the PE pipe. The positioning plate is fixedly installed with symmetrically arranged guide posts. The guide posts are slidably sleeved with symmetrically arranged sliders. A clamp strip for pressing the PE pipe is integrally connected between two corresponding sliders. A pressing plate for pressing the PE pipe is integrally connected to the clamp strip. The positioning plate is provided with a limiting structure for limiting the clamp strip.

[0007] Preferably, the guide post is vertically positioned on both sides of the positioning post, and the clamp strip is horizontally positioned at both ends of the PE pipe.

[0008] Preferably, the slider is threadedly connected to a fixing bolt that connects to the positioning plate, and the clamp strip and the pressing plate are arc-shaped structures adapted to the PE pipe.

[0009] Preferably, the limiting structure includes a support rod installed in the positioning plate, and a limiting frame extending to the clamp strip is fixedly installed on the support rod. A displacement plate is slidably sleeved in the positioning plate, and a uniformly distributed limiting post extending into the support rod is fixedly installed on the displacement plate. A spring is welded between the displacement plate and the positioning plate.

[0010] Preferably, the support rod is horizontally positioned on both sides of the PE pipe, and the limiting frame has a concave structure.

[0011] Preferably, the support rod is threaded with a locking bolt that connects to the positioning plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model uses a limiting protrusion to initially position the PE pipe and the positioning post, and a pressing plate to limit the PE pipe from both the top and bottom. The two limiting frames can limit the clamp strip, thereby ensuring the connection between the PE pipe and the positioning post. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A snap-fit ​​connection device for quick connection of PE pipe includes a PE pipe and a connecting pipe. The connecting pipe includes a hollow positioning plate 1 and a positioning post 2. The outer wall of the positioning post 2 is provided with uniformly distributed limiting protrusions that move against the inner wall of the PE pipe. The positioning post 2 and the PE pipe can be initially connected through the limiting protrusions.

[0020] The positioning plate 1 is fixedly installed with symmetrically arranged guide posts 3, and symmetrically arranged sliders 4 are slidably sleeved on the guide posts 3. The guide posts 3 are vertically arranged on both sides of the positioning post 2, and the clamp strips 5 are horizontally arranged at both ends of the PE pipe. The two corresponding sliders 4 are integrally connected with clamp strips 5 for pressing the PE pipe. The guide posts 3 guide the sliders 4 and restrict their movement direction, which can further ensure the balance of the movement of the clamp strips 5 and the pressing plate 6.

[0021] The slider 4 is threaded with a fixing bolt that connects to the positioning plate 1. The clamp strip 5 and the pressing plate 6 are arc-shaped structures adapted to the PE pipe. The clamp strip 5 is integrally connected with the pressing plate 6 for pressing the PE pipe. By setting the clamp strip 5 and the pressing plate 6 to be arc-shaped structures adapted to the PE pipe, the contact degree between the clamp strip 5 and the pressing plate 6 and the PE pipe can be increased.

[0022] The positioning plate 1 is equipped with a limiting structure to limit the clamp strip 5.

[0023] The limiting structure includes a support rod 7 installed inside the positioning plate 1, and a limiting frame 8 extending to the clamp strip 5 is fixedly installed on the support rod 7. A displacement plate 9 is slidably sleeved inside the positioning plate 1, and a uniformly distributed limiting post 11 extending into the support rod 7 is fixedly installed on the displacement plate 9. A spring 10 is welded between the displacement plate 9 and the positioning plate 1. The support rod 7 is horizontally positioned on both sides of the PE pipe. The limiting frame 8 has a concave structure. A locking bolt connected to the positioning plate 1 is threaded onto the support rod 7. The extension and retraction of the spring 10 drives the limiting post 11 to extend into the support rod 7, thereby limiting the position of the support rod 7 to both sides of the PE pipe. The limiting frame 8 extends to the clamp strip 5, preventing the pressing plate 6 from becoming loose, and further ensuring the connection between the PE pipe and the connecting pipe.

[0024] The functional principle of this utility model can be explained through the following operation methods:

[0025] Place the PE pipe onto the positioning post 2;

[0026] Press down on the two clamp strips 5 so that the clamp strips 5 and the pressing plate 6 clamp the PE pipe from the top and bottom ends. Use the fixing bolt to connect the slider 4 and the positioning plate 1.

[0027] Push the support rod 7 into the positioning plate 1, so that the support rod 7 drives the limiting frame 8 to extend onto the clamping strip 5, so that the limiting frame 8 clamps the clamping strip 5. Under the extension and retraction of the spring 10, the limiting post 11 extends into the support rod 7. Use the locking bolt to connect the support rod 7 and the positioning plate 1.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
