[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0026] A snap - on fiberglass pipe, comprising a fiberglass pipe body 1. The fiberglass pipe body 1 includes a first fiberglass pipe 101 and a second fiberglass pipe 102. One end of the inner wall of the fiberglass pipe body 1 is fixedly connected with a connecting pipe 2. The connecting pipe 2 penetrates through the fiberglass pipe body 1. The inner side of the end of the connecting pipe 2 penetrating through the fiberglass pipe body 1 is provided with sliding grooves 3 having equal groove diameters. A spring 4 is arranged inside the sliding grooves 3. A clamping block 5 is slidably connected inside the sliding grooves 3. Two ends of the spring 4 are respectively fixedly connected with the inner wall of the sliding grooves 3 and the clamping block 5. One end of the fiberglass pipe body 1 away from the connecting pipe 2 is fixedly connected with a receiving pipe 6. An arc - shaped clamping groove 7 is arranged inside the receiving pipe 6. The clamping block 5 arranged inside the connecting pipe 2 fixedly connected with the first fiberglass pipe 101 is clamped inside the clamping groove 7 arranged inside the receiving pipe 6 fixedly connected with the second fiberglass pipe 102.

[0027] An arc - shaped damping pad 8 is fixedly connected inside the clamping groove 7. The damping pad 8 is in fit with the clamping block 5. This setting enables the damping pad 8 to increase the friction force between the clamping block 5 and the clamping groove 7, so that the clamping block 5 can be more stably clamped inside the clamping groove 7. The clamping blocks 5 are arranged in an equiangular array with the same center of a circle. One side of the clamping block 5 is arc - shaped. This setting enables the clamping blocks 5 to stably connect the first fiberglass pipe 101 and the second fiberglass pipe 102 in cooperation with the clamping groove 7;

[0028] One end of the FRP pipe body 1 away from the receiving pipe 6 is fixedly connected with a protective ring 9. The protective ring 9 fixedly connected to the first FRP pipe 101 is in contact with the receiving pipe 6 fixedly connected to the second FRP pipe 102. This setting makes it so that when the block 5 is fully engaged with the slot 7, the protective ring 9 connected to the first FRP pipe 101 will be in contact with the receiving pipe 6 connected to the second FRP pipe 102, thereby protecting the first FRP pipe 101 and the second FRP pipe 102; One end of the connecting pipe 2 is fixedly connected with a first sealing ring 10. The inner wall of one end of the FRP pipe body 1 away from the connecting pipe 2 is fixedly connected with a reinforcing pipe 11. The reinforcing pipe 11 is fixedly connected with the inner wall of the receiving pipe 6. One end of the reinforcing pipe 11 is fixedly connected with a second sealing ring 12. The first sealing ring 10 is in contact with the second sealing ring 12. This setting makes it so that the reinforcing pipe 11 and the connecting pipe 2 can be more tightly connected together through the first sealing ring 10 and the second sealing ring 12. The reinforcing pipe 11 can reinforce the receiving pipe 6, enabling the receiving pipe 6 to be firmly arranged at one end of the FRP pipe body 1.

[0029] Workflow: When connecting adjacent FRP pipe bodies 1 together, that is, connecting the first FRP pipe 101 and the second FRP pipe 102 together, gradually move the connecting pipe 2 connected to the first FRP pipe 101 towards the inside of the receiving pipe 6 connected to the second FRP pipe 102. The block 5 will first be affected by the inner wall of the receiving pipe 6 connected to the second FRP pipe 102, causing the block 5 to slide inside the sliding groove 3 and act on the spring 4. The spring 4 will generate a reaction elastic force. When the block 5 moves inside the slot 7, the elastic force of the spring 4 makes the block 5 fit more closely with the damping pad 8 inside the slot 7. The damping pad 8 increases the friction between the block 5 and the slot 7, thereby enabling the block 5 to be more stably engaged inside the slot 7. Thus, through the clamping connection of the receiving pipe 6 and the connecting pipe 2, etc., the first FRP pipe 101 and the second FRP pipe 102 can be stably connected together. When the block 5 is fully engaged with the slot 7, the protective ring 9 connected to the first FRP pipe 101 will be in contact with the receiving pipe 6 connected to the second FRP pipe 102, thereby protecting the first FRP pipe 101 and the second FRP pipe 102. At the same time, the first sealing ring 10 and the second sealing ring 12 will be in contact, and the reinforcing pipe 11 and the connecting pipe 2 will be connected and communicate. The reinforcing pipe 11 can reinforce the receiving pipe 6, enabling the receiving pipe 6 to be firmly arranged at one end of the FRP pipe body 1. Then, apply a special adhesive to the outside of the protective ring 9 connected to the first FRP pipe 101 and the receiving pipe 6 connected to the second FRP pipe 102, making the first FRP pipe 101 and the second FRP pipe 102 more firmly connected together.

[0030] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
