Description

Technical Field

[0001] This utility model relates to the field of plastic pipe technology, specifically a plastic pipe with a sealing structure. Background Technology

[0002] Plastic pipes with sealing structures refer to plastic pipes that achieve excellent sealing performance through different structural designs and material selections. Existing plastic pipes with sealing mechanisms mainly include PE conduits, plastic capillary tubes, PVC-U pipes, and HDPE pipes, which have strong sealing properties and are widely used in various engineering fields.

[0003] Chinese patent CN220551614U discloses a plastic tube with a sealed structure, comprising an outer tube containing an inner tube. A partition, also fixedly connected to the outer tube, divides the space between the inner and outer tubes into a sealed storage tank. The storage tank contains fire extinguishing liquid. An outlet hole, communicating with the storage tank, is located on the outer tube, and a flammable block is placed inside the outlet hole. This application, through its dual-tube structure (inner and outer tubes), facilitates the storage of fire extinguishing liquid. Furthermore, the inclusion of a flammable block allows for the rapid discharge of the fire extinguishing liquid in the event of a fire, thus extinguishing the fire in the plastic tube. This addresses the problem that existing plastic tubes only provide fire protection but lack fire extinguishing capabilities.

[0004] The aforementioned plastic pipes have fireproof and fire-extinguishing effects, but existing plastic pipes use adhesive bonding during connection, which leads to cracking under stress during use. In addition, traditional plastic pipes do not have a sealing effect. Therefore, it is necessary to provide a plastic pipe with a sealing structure. Utility Model Content

[0007] Preferably, both ends of the first buckle and the second buckle have a semi-circular tube combination, and the limiting groove is adapted to the rubber pad.

[0008] Preferably, the connecting seats on both sides are connected to each other, and the connecting shaft consists of bolts and nuts.

[0009] Preferably, a sealing mechanism is provided between the first buckle and the second buckle. The sealing mechanism includes two sealing seats, which are respectively fixedly installed inside the first buckle and the second buckle. Sliding grooves are provided on both sides of the first buckle and the second buckle. A support is slidably installed in the sliding groove. A sealing plug is fixedly installed on the upper part of the support. Sealing gaskets are fixedly installed on both sides of the sealing plug. Slides are fixedly installed at both ends of the support. Two positioning seats are fixedly installed side by side on one side of the slides. A positioning rod is fixedly installed through the first buckle, the second buckle, and the positioning seats.

[0010] Preferably, both sealing seats are adapted to the sealing plug, and both sealing seats are composed of half of a shaped tube.

[0011] Preferably, the first buckle and the second buckle are located between the sealing gasket and the slide, and the sealing gasket and the slide are in close contact with the first buckle and the second buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This is used for plastic pipes with a sealing structure. By controlling the No. 1 and No. 2 buckles to clamp the outer pipe, and using the connecting shaft with the connecting seat to connect the No. 1 and No. 2 buckles together, the outer pipe can be reinforced by further adjusting the connecting shaft. The limiting groove and rubber gasket can be matched to increase the sealing performance of the plastic pipe.

[0023] See Figure 3 Furthermore, it is found that both ends of the first buckle 201 and the second buckle 202 are composed of semi-circular tubes, the limiting groove 203 is adapted to the rubber pad 204, the two connecting seats 205 are connected to each other, and the connecting shaft 206 is composed of bolts and nuts.

[0024] Specifically, the outer pipe 1 is clamped by the first buckle 201 and the second buckle 202, so that the limiting groove 203 is matched and connected with the rubber pad 204. Furthermore, the first buckle 201 and the second buckle 202 are connected together by the connecting shaft 206. Since the connecting shaft 206 is composed of bolts and nuts, the first buckle 201 and the second buckle 202 can be reinforced by the connecting shaft 206 to ensure the airtightness of the connection.

[0027] See Figure 4 Furthermore, based on Embodiment 1, both sealing seats 301 are adapted to sealing plugs 304, and both sealing seats 301 are composed of half of a shaped tube. The first buckle 201 and the second buckle 202 are located between the sealing gasket 305 and the slide 306, and the sealing gasket 305 and the slide 306 are in close contact with the first buckle 201 and the second buckle 202.
