Description

Technical Field

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

[0002] The connection of FRP pipes generally adopts flange connection, but the flange connection process requires the use of multiple bolts. During the long-term use of FRP pipes, it cannot be guaranteed that the bolts of the flange connection can remain intact as always. However, the traditional connection method lacks a protective structure for the bolts. Once the bolts are loose, it will affect the connection stability of the FRP pipe.

[0003] Therefore, the traditional connection method of glass fiber reinforced plastic pipes can be improved so that the above-mentioned problems can be avoided. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems and to propose a clamping type glass fiber reinforced plastic pipe.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A clamping glass fiber reinforced plastic pipe includes a pipe body, a fixing plate fixed on the pipe body, a through hole 1 and a through hole 2 formed on the fixing plate, the outer side of the pipe body abuts against a clamping ring 1, and the clamping ring 1 is rotatably connected to the clamping ring 2, the clamping ring 2 and the clamping ring 1 are clamped on the pipe body, a round rod 1 is fixed on the clamping ring 1, and a round rod 2 is fixed on the clamping ring 2, the round rod 1 and the round rod 2 respectively pass through the through hole 1 and the through hole 2, the round rod 1 is connected to a screw sleeve by a thread, and the pipe body is provided with a limiting member for limiting the screw sleeve.

[0007] Preferably, the limiting member includes a side hole on the screw sleeve, a round hole on the fixed plate, the round hole is connected to the rotating rod by a thread, an arc rod is rotatably connected to the rotating rod, a through rod is fixed on the arc rod, a through hole is opened on the fixed plate, and the through rod passes through the side hole and the through hole.

[0008] Preferably, the rotating rod is fixedly connected with a handle.

[0009] Preferably, elastic rubber gaskets protrude from the portions where the first and second clamping rings abut against the outer wall of the tube body.

[0010] Preferably, the bottom of the arc-shaped rod abuts against the fixed plate, and the notched portion on the arc-shaped rod abuts against the corresponding position of the screw sleeve.

[0011] Preferably, after the second round rod passes through the fixing plates of the two tube bodies, it is flush with the outer wall of the fixing plates.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] 1. The present application achieves a stable connection between the two pipe bodies by clamping the pipe body with clamping rings 1 and 2, and passing round rods 1 and 2 through through holes 1 and 2 on the fixing plate, and then fixing them with screw sleeves. This connection method can withstand a certain external force and ensure the structural stability of the glass fiber reinforced plastic pipe during use.

[0020] The following will be combined with the accompanying drawings in 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.

[0021] Example 1:

[0022] This utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A clamping type glass fiber reinforced plastic pipe includes a pipe body 1, a fixing plate 2 fixed on the pipe body 1, a through hole 1 3 and a through hole 2 4 formed on the fixing plate 2, a clamping ring 1 7 abutting the outside of the pipe body 1, and a clamping ring 2 8 rotatably connected to the clamping ring 1 7, the clamping ring 2 8 and the clamping ring 1 7 being clamped on the pipe body 1, a round rod 1 9 fixed on the clamping ring 1 7, a round rod 2 10 fixed on the clamping ring 2 8, the round rod 1 9 and the round rod 2 10 respectively passing through the through hole 1 3 and the through hole 2 4, the round rod 1 9 being connected to a screw sleeve 11 by a thread, and a limiting member for limiting the position of the screw sleeve 11 on the pipe body 1. After the round rod 2 10 passes through the fixing plates 2 of the two pipe bodies 1, it is flush with the outer wall of the fixing plates 2. With the cooperation of the round rod 1 9 and the round rod 2 10, the position of the clamping ring 1 7 and the clamping ring 2 8 can be limited, and after the pipe openings of the two pipe bodies 1 are clamped together, the fixing plates 2 can also be abutted.

[0024] Example 2:

[0025] The technical solution is basically the same as that of embodiment 1, except that Figure 3 As shown, the limiting member includes a screw sleeve 11 with a side hole 12, a fixed disk 2 with a circular hole 6, the circular hole 6 being threadedly connected to a rotating rod 14, a curved rod 13 being rotatably connected to the rotating rod 14, a through-rod 16 being fixed to the curved rod 13, a through-hole 5 being provided on the fixed disk 2, and the through-rod 16 passing through the side hole 12 and the through-hole 5, and a handle 15 being fixedly connected to the rotating rod 14, which can be used to conveniently control the rotation of the rotating rod 14, thereby causing the rotating rod 14 to be threadedly connected to the circular hole 6 during rotation. The bottom of the curved rod 13 abuts the fixed disk 2, and the notched portion on the curved rod 13 abuts the corresponding position of the screw sleeve 11. Elastic rubber gaskets protrude from the portions of the snap ring 1 7 and the snap ring 2 8 that abut the outer wall of the tube body 1. Therefore, after the snap ring 1 7 and the snap ring 2 8 come into contact with the outer wall of the tube body 1 during rotation, they can be clamped outside the tube body 1, so that the snap ring 1 7 and the snap ring 2 8 are fixed to the tube body 1 as a whole.

[0026] In summary, this embodiment provides a method for docking the fixing plates 2 of two tubular bodies 1, with through-hole 1 3 and through-hole 2 4 aligned. Then, the snap rings 1 7 and 2 8 are rotated, clamping them against the tubular body 1 as they rotate, pushing them to move until the round rod 1 9 fixed to the snap ring 1 7 penetrates through through-hole 1 3 and the round rod 2 10 extends into through-hole 2 4. The screw sleeve 11 is then threadedly connected to the round rod 1 9, securing the two tubular bodies 1 together.

[0027] The side hole 12 on the screw sleeve 11 is aligned with the through hole 5 on the fixed plate 2. The through rod 16 is aligned with the side hole 12. The rotating rod 14 is rotated by turning the handle 15 so that the rotating rod 14 is threadedly connected to the circular hole 6 until the arc-shaped rod 13 abuts the fixed plate 2 and the through rod 16 passes through the side hole 12 and extends into the through hole 5. The two tubes 1 are fixed.

[0028] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
