Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5The utility model provides an embodiment: a socket-locked glass fiber reinforced plastic pipe, comprising a glass fiber reinforced plastic pipe 1 and a glass fiber reinforced plastic pipe 2 9, the outer ends of the glass fiber reinforced plastic pipe 1 and the glass fiber reinforced plastic pipe 2 9 are fixedly connected with a sealing plate 2, the outer end of the sealing plate 2 is fixedly connected with a reinforcing plate 2 8, the inner part of the reinforcing plate 2 8 is provided with a limiting groove 21, the inner part of the limiting groove 21 is slidably connected with a pull rod 5, the outer part of the pull rod 5 is sleeved with a spring 22, one end of the spring 22 is fixedly connected with a moving plate 20, and the reinforcing plate 21 is fixedly connected with a reinforcing plate 20. A slide groove 7 is provided on the outside of the fixing plate 28, a spring 16 is fixedly connected inside the slide groove 7, one end of the spring 16 is fixedly connected to a fixing column 6, the other ends of the outsides of the FRP pipe 1 and the FRP pipe 29 are fixedly connected to a sealing plate 2 10, the outside of the sealing plate 2 10 is fixedly connected to a reinforcement plate 4, the outside of the reinforcement plate 4 is fixedly connected to a plug-in plate 11, a limiting hole 12 is provided on the outside of the plug-in plate 11, and sealing components are installed inside the FRP pipe 1 and the FRP pipe 29.

[0032] Specifically, by adjusting the position of the fixing column 6, the pull rod 5 is controlled, thereby controlling the movement and locking of the plug board 11. The plug board 11 can ensure the correct position and direction through the design of the limit hole 12 when connected. At the same time, the plug board 11 is firmly inserted into the slot 23 and fixed so that the pull rod 5 fixes the plug board 11. The spring 22 plays a buffering and supporting role in the connection process, ensuring that the plug board 11 can be correctly locked in the slot 23 at the appropriate time. Through the setting of the limit slot 21, a sliding track is provided for the pull rod 5, so that the pull rod 5 can move smoothly. This process is convenient for operators to use and improves efficiency.

[0033] Reference Figure 2 and Figure 3 The seal directly includes a first plug-in sleeve 3, one side of the first plug-in sleeve 3 is fixedly connected to the outside of the FRP pipe 1, the inside of the first plug-in sleeve 3 is fixedly connected with a sealing ring 19, the outside of the FRP pipe 1 is fixedly connected with a connecting sleeve 18, the outside of the FRP pipe 2 9 is provided with a plug-in groove 14, and the inside of the FRP pipe 2 9 is fixedly connected with a second plug-in sleeve 15.

[0034] Specifically, the first plug-in sleeve 3 and the second plug-in sleeve 15 are the main connecting components, which are respectively inserted into specific positions of the FRP pipe 1 and the FRP pipe 2 9 so that the two pipes can be tightly connected together. Secondly, the sealing ring 19 plays a vital role in the connection. It is fixedly connected to the inside of the first plug-in sleeve 3. When the first plug-in sleeve 3 is inserted into the plug-in groove 14, the sealing ring 19 can fit tightly with the corresponding pipe surface to prevent liquid or gas from leaking from the connection.

[0035] Reference Figure 5The other end of the spring 22 is fixedly connected to the inside of the limiting groove 21, the outside of the movable plate 20 is slidably connected to the inside of the limiting groove 21, a slot 23 is provided inside the reinforcing plate 8, the outside of the plug-in board 11 fits with the inside of the slot 23, one end of the pull rod 5 is inserted into the inside of the limiting hole 12, and the other end of the pull rod 5 extends to the outside of the reinforcing plate 8 and is fixedly connected to the handle 13.

[0036] Specifically, the movement of the movable plate 20 is driven by the tension of the contraction of the spring 22, and the pull rod 5 is moved at the same time. Through the setting of the slot 23, the plug-in board 11 is inserted into the interior of the reinforcement plate 8, and one end of the pull rod 5 is inserted into the interior of the limiting hole 12. The handle 13 is pulled by external force, so that the pull rod 5 moves inside the limiting slot 21.

[0037] Reference Figure 3 A connecting hole 17 is opened on the outside of the pull rod 5, the outside of the fixing column 6 is slidably connected to the inside of the connecting hole 17, the outside of the first plug-in sleeve 3 is slidably connected to the inside of the plug-in groove 14, the outside of the second plug-in sleeve 15 is slidably connected to the inside of the connecting sleeve 18, and a waterproof sleeve is provided on the outside of the sealing ring 19.

[0038] Specifically, through the setting of the connecting hole 17, the fixing column 6 is inserted into the interior of the pull rod 5, thereby fixing the position of the pull rod 5 so that the pull rod 5 will not move. The first plug-in sleeve 3 is connected to the interior of the plug-in groove 14, so that the FRP pipe 1 and the FRP pipe 2 9 are connected. At the same time, the second plug-in sleeve 15 is plugged into the connecting sleeve 18, so that the FRP pipe 1 and the FRP pipe 2 9 are connected more tightly. At the same time, under the action of the sealing ring 19, the connection has a good sealing effect to prevent water leakage and seepage.

[0039] Working principle: when it is necessary to install and connect the FRP pipe 1 and the FRP pipe 2 9, the reinforcing plate 2 8 and the reinforcing plate 1 4 can be connected relatively at this time, and the fixing column 6 can be moved to the right by external force, so that the fixing column 6 is separated from the connecting hole 17, and then the handle 13 is pulled outward to move the pull rod 5, and at the same time, the spring 22 is compressed inside the limiting groove 21, so that the plug-in plate 11 is inserted into the inside of the card slot 23, and the handle 13 is pushed at the same time, so that the pull rod 5 moves to the inside of the limiting hole 12, so that the plug-in plate 11 is fixed inside the card slot 23 under the insertion of the pull rod 5, and the fixing column 6 is moved to the left, so that the fixing column 6 is inserted into the inside of the connecting hole 17, and the spring 16 releases the tension, so that the fixing column 6 can limit the movement of the pull rod 5, so that the plug-in plate 11 is more stably inside the reinforcing plate 2 8, so that the FRP pipe 1 and the FRP pipe 2 9 are in a stable position during the installation process, making the installation process faster and more convenient. This simplicity saves installation time and labor costs;

[0040] Secondly, the first plug-in sleeve 3 fixedly connected to the outside of the FRP pipe 1 is inserted into the inside of the plug-in groove 14, so that the second plug-in sleeve 15 is inserted into the inside of the connecting sleeve 18, wherein the sealing ring 19 can make the connection between the FRP pipe 1 and the FRP pipe 2 9 have good sealing properties to prevent water leakage.
