Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic pipes, in particular to a glass fiber reinforced plastic pipe that is easy to connect. Background Art

[0002] FRP pipes are lightweight, high-strength, and corrosion-resistant non-metallic pipes. They are made of heavy glass fibers wrapped in a resin matrix, layer by layer, around a rotating mandrel according to process requirements. Quartz sand is evenly spaced between the fibers as a sand layer. The pipe wall structure is rational and advanced, fully utilizing the material's properties. While maintaining sufficient strength, it also improves rigidity, ensuring product stability and reliability.

[0003] When laying FRP pipes, it is necessary to dock two adjacent pipes. In order to improve the stability of pipe docking, the patent with publication number CN215568653U discloses a FRP pipe that is easy to connect. By turning the knob, the driving shaft, bevel gear one and bevel gear two are driven to rotate, thereby driving bevel gear three, bevel gear four and the driven shaft to rotate through the transmission shaft, so that the screw rotates, driving the slider to move, so that the rod is inserted into the socket for further connection. However, the structure of the pipe docking part is too complicated, and it is difficult to manufacture in the early stage, which will increase the production cost. Secondly, like the existing pipes, there is no protective structure on the outside of the pipe. Once the pipe encounters a collision during the laying process, it is easy to cause the side wall of the pipe to rupture, so it needs further improvement. Utility Model Content

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.

[0024] like Figure 1-Figure 5 As shown, it relates to a glass fiber reinforced plastic pipe that is easy to connect, including a pipe 1, an annular slot 2 is opened at one end of the pipe 1, an annular plug plate 3 is fixed to the end of the pipe 1 away from the annular slot 2, and the annular plug plate 3 matches the annular slot 2, a plurality of card slots 31 are opened on the outer wall of the annular plug plate 3, a plurality of card slots 31 are provided on the inner wall of the annular slot 2, a plurality of bolts 5 are passed through and threadedly connected to the side wall of the annular slot 2, a first ring plate 8 and a second ring plate 9 are fixedly connected at both ends of the surface of the pipe 1, and a plurality of protective components 10 are fixedly connected between the first ring plate 8 and the second ring plate 9.

[0025] The clamping assembly 4 includes a groove 41 formed on the inner wall of the annular slot 2 . A spring 42 is fixedly connected to the inner wall of the groove 41 . A latching tooth 43 is fixedly connected to the other end of the spring 42 . The latching tooth 43 , which is away from the spring 42 , can be clamped into the inside of the clamping slot 31 .

[0026] When connecting two adjacent pipes 1, the annular plug plate 3 on one of the pipes 1 is inserted into the annular slot 2 on the other pipe 1. During the connection process, the position of the clamping component 4 is aligned with the clamping slot 31. During the insertion of the annular plug plate 3 into the annular slot 2, the clamping teeth 43 will be squeezed back into the groove 41. When the position of the clamping teeth 43 coincides with the clamping slot 31, the spring 42 squeezes the clamping teeth 43 into the clamping slot 31, thereby achieving the preliminary connection and fixation of the two pipes 1.

[0027] The end of the latching tooth 43 away from the spring 42 is designed to be inclined.

[0028] By designing the latching teeth 43 as inclined surfaces, the latching teeth 43 can be pressed back into the groove 41 more easily.

[0029] A plurality of threaded holes 32 for screwing the bolts 5 are formed on the surface of the annular insert plate 3 .

[0030] After the two pipes 1 are preliminarily connected and fixed by the clamping assembly 4 and the clamping slot 31 , the bolt 5 can be screwed into the threaded hole 32 to further fix the annular insert plate 3 in the annular slot 2 .

[0031] An annular clamping groove 6 is provided at one end of the pipe 1 close to the annular slot 2 , and a sealing ring 7 is clamped inside the clamping groove 6 .

[0032] The sealing ring 7 can increase the sealing performance between the two connected pipes 1 .

[0033] The protective assembly 10 includes a screw 101 and a cross bar 102 fixed to the surface of the first ring plate 8. The end of the cross bar 102 close to the first ring plate 8 is fixedly connected to the end plate 103. The second ring plate 9 is provided with a plurality of through holes 91 for passing the cross bar 102. The surface of the end of the cross bar 102 away from the end plate 103 is slidably sleeved with an internal threaded sleeve 104. The internal threaded sleeve 104 is screwed to the surface of the screw 101. The end of the cross bar 102 located in the internal threaded sleeve 104 is fixedly connected to an anti-slip plate 105. The size of the through hole 91 is larger than the internal threaded sleeve 104 and smaller than the end plate 103.

[0034] The protective components 10 are evenly spaced between the first ring plate 8 and the second ring plate 9 to prevent damage to the pipeline 1 from collisions. If a crossbar 102 is damaged, the internally threaded sleeve 104 at the end of the crossbar 102 can be unscrewed from the corresponding screw 101. The crossbar 102, connected to the internally threaded sleeve 104, can then be removed from the through-hole 91. A new crossbar 102 can then be replaced, and the end of the crossbar 102 with the internally threaded sleeve 104 can be passed through the through-hole 91. The internally threaded sleeve 104 can then be screwed onto the screw 101 to secure the crossbar 102 between the first ring plate 8 and the second ring plate 9.

[0035] The outer side wall of the internal thread sleeve 104 is provided with anti-skid patterns to prevent the internal thread sleeve 104 from slipping when being twisted.

[0036] Working Principle: When connecting two pipes 1, the annular insert 3 on one pipe 1 is inserted into the annular slot 2 on the other pipe 1. The spring 42 of the clamping assembly 4 squeezes the clamping teeth 43 into the clamping slot 31, achieving the initial connection and fixation of the two pipes 1. Then, the bolt 5 is screwed into the threaded hole 32 to further fix the annular insert 3 in the annular slot 2, thereby connecting and fixing the two pipes 1. This fiberglass pipe has a simple structure and is faster and more convenient when connecting two adjacent pipes 1. The protective assembly 10 located on the outside of the pipe 1 can prevent the pipe 1 from being directly hit and ruptured.
