The buckle structure between the upper and lower glands of the locking device may not be tightly fastened during use. After a period of use, the two glands will expand, resulting in the disappearance of the locking state, and the stability is low. Utility Model Content

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0021] according to Figure 1 , 2 As shown in Figure 3, a glass fiber reinforced plastic pipe connection locking device is proposed in this embodiment, including a three-way joint. The three-way joint includes two upper and lower clamping sleeves 1, and a rotating pin 4 is provided on the back of the clamping sleeve 1. The two clamping sleeves 1 rotate relative to each other through the rotating pin 4; the longitudinal pipe and the transverse pipe to be connected are placed between the two clamping sleeves 1, and the upper clamping sleeve 1 is rotated to clamp the upper end of the other clamping sleeve 1 to lock the pipe.

[0022] A pressing plate 2 is provided at the upper end of the upper ferrule 1, and a bottom plate 3 is provided at the lower end of the lower ferrule 1. The pressing plate 2 and the bottom plate 3 are fixedly connected to the two ferrules 1 respectively.

[0023] Two adjusting bolts 10 are provided at one end of the bottom plate 3 away from the ferrule 1, and the two adjusting bolts 10 are rotatably connected to the two sides of the bottom plate 3. Two locking components are provided at one end of the pressing plate 2 away from the ferrule 1, and two card seat structures are fixedly connected to the two sides of the ferrule 1. The upper end of the adjusting bolt 10 is provided with an adjusting component engaged with the card seat structure. After the two ferrules 1 are buckled, the adjusting bolts 10 on both sides of the ferrule 1 are rotated, and the adjusting components on the upper ends of the adjusting bolts 10 are moved to the two sides of the pressing plate 2. The card seat structure is engaged through the adjusting component to lock the upper end of the adjusting bolt 10. Since the lower end of the adjusting bolt 10 is rotatably connected to the bottom plate 3, the pressing plate 2 and the bottom plate 3 will be firmly closed together through the two adjusting bolts 10, ensuring that the ferrule 1 in the engaged state will not expand, thereby improving the safety of the steel pipe connection.

[0024] Specifically, first pipe joints 5 are provided on both sides of the ferrule 1, and second pipe joints 6 are provided on the front side of the ferrule 1, and the second pipe joints 6 are connected to the first pipe joints 5. The two ferrules 1 are clamped on the outside of the pipes to be connected, and after the two ferrules 1 are clamped together, the first pipe joints 5 on both sides of the ferrule 1 fix the transversely arranged pipes, and the second pipe joints 6 fix the longitudinally arranged pipes.

[0025] More specifically, two hinge seats 9 are provided at one end of the bottom plate 3 away from the ferrule 1, and the two hinge seats 9 are respectively fixedly connected to the two sides of the bottom plate 3, and the two hinge seats 9 are respectively rotatably connected to the lower ends of the two adjustment bolts 10. The lower ends of the adjustment bolts 10 are rotatably connected to the hinge seats 9 through movable pins, and the adjustment bolts 10 can rotate around the movable pins and stand up from the two sides of the bottom plate 3.

[0026] Regarding the adjustment assembly and the seat structure: the adjustment assembly includes a nut 14, which is sleeved on the upper end of the adjustment bolt 10, and the nut 14 is threadedly connected with the threaded surface opened on the outside of the adjustment bolt 10. By turning the nut 14, the nut 14 can rotate along the threaded surface on the outside of the adjustment bolt 10 to adjust the height.

[0027] The card seat structure includes a U-shaped card 12, which is fixedly connected to both sides of the pressure plate 2. Two baffles 16 are provided at the upper end of the U-shaped card 12, and a card slot 13 is provided between the two baffles 16. The card slot 13 is opened at the end of the U-shaped card 12 away from the pressure plate 2. The width of the U-shaped card 12 is greater than the diameter of the adjustment bolt 10, and the width of the U-shaped card 12 is less than the diameter of the nut 14. After the adjustment bolt 10 is bent into the card slot 13, the nut 14 is rotated, and the nut 14 will fall into the upper end of the U-shaped card 12 and fix the pressure plate 2 and the bottom plate 3. At this time, the baffles 16 on both sides of the card slot 13 will limit the nut 14, so that the nut 14 will not detach from the upper end of the U-shaped card 12, and the safety is strong.

[0028] In order to reduce the collision damage between the U-shaped clamp 12 and the nut 14, a gasket 15 is provided at the lower end of the nut 14, and the gasket 15 is sleeved on the outside of the adjustment bolt 10, and the gasket 15 is slidably connected with the adjustment bolt 10. The gasket 15 is arranged between the nut 14 and the U-shaped clamp 12, which can protect the nut 14 and the U-shaped clamp 12 and improve the service life of the U-shaped clamp 12 and the nut 14.

[0029] In order to facilitate the staff to open or close the pressing plate 2 and the bottom plate 3, a groove 7 is provided at one end of the pressing plate 2 and the bottom plate 3 away from the ferrule 1, and a grip 8 is provided in the groove 7, and both ends of the grip 8 are rotatably connected to the groove wall of the groove 7. The grip 8 is convenient for the user to hold, and there will be no problem of hurting the hand when the pipeline is compressed.

[0030] The upper end of the articulated seat 9 is equipped with a plurality of first fixing bolts 11, which are threadedly connected to the bolt holes opened at the upper end of the bottom plate 3. The upper end of the U-shaped clamp 12 is equipped with a plurality of second fixing bolts 17, which are threadedly connected to the bolt holes opened at the upper end of the pressing plate 2. The articulated seat 9 and the U-shaped clamp 12 are fixed to the pressing plate 2 and the bottom plate 3 by bolt connection, which is convenient for the staff to replace the various components of the locking device.

[0031] Working principle: The longitudinal pipe and the transverse pipe to be connected are placed between two ferrules 1. The ferrule 1 on the upper side is rotated to engage the upper end of the other ferrule 1 to lock the pipe. After the two ferrules 1 are buckled, the adjustment bolts 10 on both sides of the ferrules 1 are rotated, and the adjustment components on the upper end of the adjustment bolts 10 are moved to both sides of the pressure plate 2. The seat structure is engaged through the adjustment component to lock the upper end of the adjustment bolt 10. Since the lower end of the adjustment bolt 10 is rotatably connected to the bottom plate 3, the pressure plate 2 and the bottom plate 3 will be firmly combined through the two adjustment bolts 10, ensuring that the ferrule 1 in the engaged state will not expand, thereby improving the safety of steel pipe connection.
