Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, in particular to a reinforced glass fiber PP-R composite pipe. Background Art

[0002] Composite pipe is a widely used and mature pipe material. However, its disadvantage is poor flexibility and easy breakage. It can meet most needs under normal circumstances, such as being used as a catheter. However, when used in certain special environments (such as underwater), the pipe is required to be impact-resistant.

[0003] According to a disclosed impact-resistant composite pipe (publication number: CN203868539U), it includes a composite pipe with a protective steel pipe nested on its outer side. Several fixing rings are evenly distributed on the outer side of the composite pipe. Several bolts of adjustable length are evenly distributed on the protective steel pipe. Springs are fixedly mounted on the bolts, and the other side of the springs is fixedly connected to the fixing rings. The composite pipe, protective steel pipe, and spring surfaces are all provided with an anti-corrosion layer. Due to the adoption of this technical solution, the composite pipe is more durable and convenient when used in liquid environments or windy and wavey environments. It has the advantages of a simple structure, easy maintenance, low processing cost, corrosion resistance, impact resistance, and high production efficiency. However, in the above device, the interaction between the composite pipe and the fixing rings makes it difficult to achieve the effect of quickly connecting a second pipe when the pipe length is insufficient, resulting in reduced work efficiency. Therefore, we have proposed a reinforced glass fiber PP-R composite pipe specifically for quickly connecting a second pipe. Utility Model Content

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] like Figures 1 to 3 This embodiment provides a reinforced glass fiber PP-R composite pipe, including a pipe mechanism 1, which includes a pipe A101. A protective sleeve 102 is fixedly connected to one end of the pipe A101. A pipe B103 is fixedly connected to the inner wall of the protective sleeve 102 at the end away from the pipe A101. A threaded sleeve 104 is fixedly connected to the end of the pipe B103 away from the protective sleeve 102.

The end of the pipeline A101 away from the protective sleeve 102 is fixedly connected to the connecting sleeve A201, and a clamping block 202 is fixedly connected to the circumferential surface of the connecting sleeve A201.

The above design is conducive to completely isolating the external air from penetrating into the pipe through three layers of different materials, thereby inhibiting the growth of algae and keeping the water fresh and pure.

[0031] The clamping block 202 is located on the displacement track of the clamping sleeve 205, and the push block 208 is L-shaped.

The above design is conducive to convenient and quick connection with the water pipe and disassembly and replacement.

[0035] There are four positioning blocks 301, which are arranged in groups of two and are symmetrical with each other along the vertical center axis of the fixing ring 105. There are four screw rods 302, which are arranged in groups of two and are symmetrical with each other along the vertical center axis of the fixing ring 105. The above design is conducive to limiting the two fixing rings 105 through the four screw rods 302.

[0036] There are four short rods 303, which are arranged in groups of two and are symmetrical with each other along the vertical center axis of the fixing ring 105. There are four snap rings 304, which are arranged in groups of two and are symmetrical with each other along the vertical center axis of the fixing ring 105. The above design is conducive to limiting the snap rings 304 through the four short rods 303.

[0037] The diameter of the retaining ring 304 is consistent with the diameter of the screw rod 302, the inner diameter of the retaining ring 304 is larger than the diameter of the short rod 303, and the circumferential surface of the retaining ring 304 is located on the displacement trajectory of the electric telescopic rod 307 away from the end of the limit plate 306. The above design is conducive to driving the retaining ring 304 to move vertically when pulling out the screw rod 302.

[0038] There are four limit plates 306, which are arranged in groups of two and arranged in a circular array on the circumferential surface of the fixed ring 105. There are four electric telescopic rods 307, which are arranged in groups of two and are symmetrical with each other along the vertical central axis of the fixed ring 105.

The size of the connecting sleeve A201 is consistent with the size of the connecting sleeve B203. The above design is conducive to pushing the clamping sleeve 205 to move by the push block 208.

[0040] The circumferential surface of the short rod 303 is located on the displacement track inside the clamping ring 304, and the bottom of the fixing ring 105 is located on the displacement track of the clamping ring 304. The above design is conducive to fixing the pipe B103 and the water pipe through the mutual contact between the clamping ring 304 and the fixing ring 105.

[0041] In this embodiment, the end of the screw rod 302 away from the positioning block 301 is inserted into the top of the fixing ring 105, and the clamping ring 304 is pushed by the electric telescopic rod 307 to cause the clamping ring 304 to move horizontally, thereby causing the clamping ring 304 to contact the bottom of the fixing ring 105, thereby achieving the effect of quickly fixing the water pipe. When the water pipe needs to be replaced, the electric telescopic rod 307 is driven by an external power supply to move the electric telescopic rod 307 away from the clamping ring 304, and then the clamping ring 304 is pushed to move the center point of the clamping ring 304 to the same point as the center point of the screw rod 302. Then, by pulling out the positioning block 301, the positioning block 301 can drive the screw rod 302 and the clamping ring 304 away from the fixing ring 105, thereby achieving the purpose of convenient disassembly.
