Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to a spliced ​​PP corrugated pipe. Background Art

[0002] Bellows have a wide range of functions. They can be used as measuring elements to convert the generated pressure into displacement or force. They can also be used as isolation materials to separate two different materials for protection. They can also be used as compensation elements to compensate for the temperature error generated by the elements, or used for the connection between two elements, etc. The different functions of the bellows will cause the length of the bellows to change accordingly.

[0003] After searching, it was found that a Chinese patent with publication number CN210344585U discloses a spliced ​​PP corrugated pipe. During daily assembly, the male tenon of the corrugated half-pipe two can be slid into the female groove of the corrugated half-pipe one along the length direction to quickly complete the assembly of the corrugated half-pipe one and the corrugated half-pipe two. At the same time, the sealing strip of the corrugated half-pipe one along the length direction at the assembly surface is squeezed and deformed to ensure the sealing at the assembly surface, thereby ensuring that the corrugated half-pipe one and the corrugated half-pipe two have good sealing performance during use after being assembled.

[0004] However, when the length of the corrugated pipe is long, as the length of the male tenon sliding into the female groove increases, the friction between the female groove and the male tenon increases, causing a gradual increase in sliding. At the same time, impurities falling into the female groove and the bending of the corrugated half-tube will increase friction, thereby causing difficulty in splicing the two corrugated half-tubes. Therefore, a new solution is needed to solve this problem. Utility Model Content

The two ends of the slider are slidably set in the two sliding grooves, and the inner wall of the slider is slidably set with the outer surfaces of the connecting plate 1 and the connecting plate 2.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1.

[0023] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model spliced ​​PP corrugated pipe comprises a first half pipe 1 and a second half pipe 2. Two connecting plates 1 3 are symmetrically arranged on the first half pipe 1, and two connecting plates 2 4 are symmetrically arranged on the second half pipe 2. A clamping strip 5 is arranged on the second half pipe 2. A clamping groove 6 is arranged on the connecting plate 1 3 at a position corresponding to the clamping strip 5. The clamping strip 5 and the connecting plates 1 3 and 2 4 are all made of PP material. The connecting plates 1 3 and 2 4 are integrally formed with the corresponding first half pipe 1 or second half pipe 2. A slider 7 is slidably arranged on the connecting plate 2 4 and the connecting plate 1 3.

[0024] When splicing the first half pipe 1 with the second half pipe 2, first insert the same end of the two clamping strips 5 on the connecting plate 2 4 into the clamping groove 6 at the corresponding position, then install the slider 7 on the connecting plate 1 3 and the connecting plate 2 4, and push the slider 7 to slide on the connecting plate 1 3 and the connecting plate 2 4, so that the entire clamping strip 5 is gradually clamped into the clamping groove 6, thereby realizing the splicing between the first half pipe 1 and the second half pipe 2, and can realize the rapid splicing of corrugated pipes of different lengths.

[0025] like Figure 1 , Figure 3As shown in the figure, sliding grooves 8 are provided on the sides of connecting plate 1 and connecting plate 2 that are away from each other. The slider 7 is set in a "C" shape. The two ends of the slider 7 are slidably arranged in the two sliding grooves 8, and the inner wall of the slider 7 is slidably arranged on the outer surfaces of connecting plate 1 and connecting plate 2. By restricting the position of the slider 7 through the sliding groove 8, the connection stability between the slider 7 and connecting plate 1 and connecting plate 2 is improved, preventing misalignment between connecting plate 1 and connecting plate 2, thereby achieving an improved splicing effect.

[0026] As Figure 3 shown in the figure, a convex block 12 is provided on the second half pipe 2, and a groove 13 is provided on the first half pipe 1 at the corresponding position of the convex block 12. The convex block 12 and the groove 13 have the same shape, and the side of the convex block 12 close to the groove 13 is chamfered. When splicing the first half pipe 1 and the second half pipe 2, the convex block 12 is inserted into the corresponding groove 13, thereby restricting the relative position between the first half pipe 1 and the second half pipe 2 and improving the connection stability between the first half pipe 1 and the second half pipe 2.

[0027] As Figure 2 、 Figure 3 shown in the figure, a first fixing hole 9 is provided on the connecting plate 1, and a second fixing hole 10 is provided on the connecting plate 2. A fixing bolt 11 is provided between the first fixing hole 9 and the connecting plate 2. The first fixing hole 9 is provided in a long strip shape, and a certain misalignment can be achieved between the positions of the first fixing hole 9 and the second fixing hole 10, improving the splicing property during the installation of the fixing bolt 11. By passing the fixing bolt 11 through the first fixing hole 9 and the second fixing hole 10, the specified positions of the first half pipe 1 and the second half pipe 2 are strengthened. By arranging the fixing bolt 11 at both ends of the first half pipe 1 and the second half pipe 2, the separation of the card strip 5 and the card slot 6 is avoided. By arranging the fixing bolt 11 at the turning position of the first half pipe 1 and the second half pipe 2, the splicing effect is improved.

[0028] As Figure 1 、 Figure 4 shown in the figure, the card strip 5 is set in a "Ji" shape, the card slot 6 has the same shape as the card strip 5, and a gap is provided between the card slot 6 and the card strip 5, increasing the clamping effect between the card strip 5 and the card slot 6 and increasing the connection stability between the connecting plate 1 and the connecting plate 2.

[0029] As Figure 3 shown in the figure, sealing gaskets are provided on the inner wall of the groove 13 and the outer surface of the convex block 12. The sealing gaskets on the groove 13 and the convex block 12 have the same thickness. When the convex block 12 is inserted into the groove 13, the sealing gaskets are mutually extruded to achieve a sealing effect.
