DETAILED DESCRIPTION

[0025] Referring Figures 1 to 5 , the utility model provides a kind of bell and spigot joint cooling pipe, it includes water outlet pipe 1 and water inlet pipe 2, water outlet pipe 1 front surface fixed installation has bell 5, water inlet pipe 2 rear surface fixed installation has spigot 6, bell 5 and spigot 6 outer surface sleeve installation has upper protective cover 3 and lower protective cover 4, protective cover can also reduce dust, impurity and other foreign matter into the connecting place of bell 5 and spigot 6, avoid the influence sealing performance due to foreign matter.

[0026] Upper protective cover 3 and lower protective cover 4 inner side surface close to rear position fixed installation has first limiting piece 8, upper protective cover 3 and lower protective cover 4 inner side surface close to front position fixed installation has second limiting piece 9.

[0027] Specifically, glue pouring groove 11 is formed between first limiting piece 8 and second limiting piece 9, and glue pouring groove 11 is used to receive sealant.

[0028] Specifically, glue pouring port 7 is provided on the upper surface of upper protective cover 3 at the center position, a sealing plug is spirally installed on glue pouring port 7, glue pouring port 7 penetrates through upper protective cover 3 and is in communication with glue pouring groove 11, and the design of glue pouring groove 11 and glue pouring port 7 facilitates further sealing of the connecting portion of bell 5 and spigot 6 by glue pouring, enhances the sealing performance of the joint, prevents water leakage, and the glue formed after glue pouring can increase the friction between bell 5 and spigot 6, so that the connection is more stable and can resist vibration and displacement in the pipeline system to a certain extent.

[0029] The lower surfaces of the first limiting piece 8 and the second limiting piece 9 on the upper protective cover 3 are provided with buckle grooves 10. The upper surfaces of the first limiting piece 8 and the second limiting piece 9 on the lower protective cover 4 are fixedly provided with buckles 12 corresponding to the buckle grooves 10 and buckled in the buckle grooves 10.

[0030] The upper protective cover 3 and the lower protective cover 4 can be combined to move around the socket 5 and the spigot 6 by using the glue pouring groove 11. In the glue pouring process, the upper protective cover 4 and the lower protective cover 4 can move around the socket 5 and the spigot 6, which facilitates the glue to be evenly applied on the sealing piece, so that the socket 5 and the spigot 6 are better glued, and the structural sealing performance and the overall strength are improved.

[0031] Meanwhile, after the glue pouring is completed, the unused glue can be recycled by inverting the glue pouring port 7, thereby saving the production cost.

[0032] The front surface of the socket 5 is fixedly provided with a first sealing ring 13, and the front surface of the first sealing ring 13 is designed as a flat surface. The rear surface of the spigot 6 is fixedly provided with a second sealing ring 14, and the rear surface of the second sealing ring 14 is designed as a flat surface.

[0033] The first sealing ring 13 and the second sealing ring 14 can be mutually adhered by the relatively designed flat surfaces. After the first sealing ring 13 and the second sealing ring 14 are adhered, they correspond to the glue pouring groove 11. The two sealing rings are adhered by the relatively flat surfaces, thereby forming an effective sealing line to prevent water from leaking from the connection between the socket 5 and the spigot 6. Corresponding to the glue pouring groove 11, the glue pouring can be used to further enhance the sealing effect, thereby double guaranteeing the sealing performance.

[0034] A first limiting groove 15 is arranged between the socket 5 and the first sealing ring 13 and close to the first sealing ring 13, and the first limiting groove 15 corresponds to the first limiting piece 8.

[0035] Specifically, a circular ring 16 is fixedly arranged in the socket 5. The circular ring 16 plays a limiting role on the spigot 6. When water flows from the water outlet pipe 1 to the water inlet pipe 2, the circular ring 16 plays a protective role on the connection between the socket 5 and the spigot 6, thereby preventing water from flowing out of the connection for a long time.

[0036] A second limiting groove 17 is arranged between the spigot 6 and the second sealing ring 14 and close to the second sealing ring 14, and the second limiting groove 17 corresponds to the second limiting piece 9.

[0037] Specifically, an inclined surface 18 is arranged on the rear surface of the spigot 6. The inclined surface 18 guides the forward water flow to smoothly pass through the joint area, thereby forming a good seal. A round corner 19 is arranged on the inclined surface 18, and the round corner 19 is adhered to the circular ring 16.

[0038] In the socket joint structure, the socket 6 is smaller in diameter than the spigot 5. When the water flows in the normal direction from the inlet pipe 2 to the outlet pipe 1, the water flow direction is consistent with the flow direction formed by the sealing structure of the socket joint. When the water flows through the joint area, the water flow is guided by the inclined surface 18 and can smoothly pass through the joint area.

[0039] When the water flows in the reverse direction from the outlet pipe 1 to the inlet pipe 2, the water flow direction is opposite to the flow direction in the normal direction and is opposite to the initial sealing force of the joint. Under the long-time water flow impact, the conventional socket joint is prone to water leakage at the connection. However, the design that the fillet 19 is in contact with the circular ring 16 can play a key role. On the one hand, the arc profile of the fillet 19 can effectively disperse the impact force of the reverse water flow, avoid the sealing failure caused by the concentrated force, and the impact force will spread to all directions along the arc surface after the water flow impacts the fillet 19, reducing the pressure on the local connection. On the other hand, the contact between the socket 6 and the spigot 5 is more close and uniform due to the contact design, so that the sealing performance can be maintained to a certain extent even under the impact of the reverse water flow, reducing the risk of water leakage.

[0040] In use, the socket 6 of the inlet pipe 2 is aligned with the spigot 5 of the outlet pipe 1 to preliminarily sleeve the spigot 5 and the socket 6, realize the connection between the outlet pipe 1 and the inlet pipe 2, sleeve the upper protective cover 3 and the lower protective cover 4 on the outer surface of the spigot 5 and the socket 6 to form external protection for the spigot 5 and the socket 6, and then inject the sealant into the sealant pouring groove 11 through the pouring port 7 on the upper surface of the upper protective cover 3. Since the first limiting part 8 and the second limiting part 9 determine the position of the sealant pouring groove 11, the accuracy of the sealant pouring operation is ensured. During the sealant pouring process, the upper and lower protective covers can make circumferential motion around the spigot 5 and the socket 6, so that the sealant can be evenly applied on the sealing part, the sealant can better glue the spigot 5 and the socket 6, the sealing performance of the joint is enhanced, the friction between the spigot 5 and the socket 6 is increased after the sealant is poured, the stability of the overall structure is enhanced, the user can conveniently perform the gluing treatment, and the unused sealant can be recycled through the inverted pouring port 7 after the sealant pouring is completed, saving the production cost.
