[0003] There are many existing methods for connecting pipe fittings. Among them, the threaded connection method is relatively common. However, the threaded part is exposed to a corrosive environment for a long time, which easily causes the threads to be damaged, thereby affecting the sealing performance and strength of the connection. At the same time, it is more troublesome to use tools to lock it, and in some narrow environments, the corroded pipe fittings are also difficult to disassemble and maintain during maintenance, reducing the convenience of pipe fitting connection.

[0005] The utility model provides the following technical solutions:
[0006] It includes a pipeline and a retaining ring. The retaining ring is hinged to the connection part of the pipeline. It is characterized in that one side of the retaining ring is connected with a structure box. A connection hole is opened at the bottom of the structure box, and a clamping mechanism is arranged inside the structure box; the clamping mechanism includes a connection column, a fixing groove, a round shaft, a gear ring, a gear part, a connection plate, a fixing block, and a compression spring.

The connection plates are respectively fixedly connected to one end of the gear part. One end of the fixing block is respectively fixedly connected to the inner side of the connection plate. The other end of the fixing block penetrates into the fixing groove. One end of the compression spring is fixedly connected to the inner wall of the structure box, and the other end of the compression spring is fixedly connected to the outer side of the connection plate.
[0007] Furthermore, sliding parts are fixedly connected to the tops of the gear parts. A sliding rod is fixedly connected inside the structure box, and the sliding parts are respectively fixedly connected to the surface of the sliding rod.

After one side of the tooth part moves outward, it can drive the engaged tooth ring to rotate on the surface of the round shaft. At the same time, the tooth ring will drive the other engaged tooth part to move outward. When the tooth parts move outward at the same time, the fixing block can be driven to move outward through the connecting plate, and the compression spring will be squeezed. Then, after the connecting column is inserted into the structure box, the snap ring is pressed tightly. Then, when the hand is released from the pull plate, the connecting plate and the fixing block can be pushed to move inward at the same time under the rebounding force of the compression spring.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.
[0021] Please refer to Figures 1-4, including a pipe 1 and a clamping ring 101. The clamping ring 101 is hinged to the connection part of the pipe 1. One side of the clamping ring 101 is connected with a structure box 2. A connection hole 201 is opened at the bottom of the structure box 2. A clamping mechanism is arranged inside the structure box 2;The clamping mechanism includes a connecting column 202, a fixing groove 203, a circular shaft 204, a gear ring 205, a gear member 206, a connecting plate 207, a fixing block 208, and a compression spring 209. One end of the connecting column 202 is fixedly connected to the end of one side of the clamping ring 101. The other end of the connecting column 202 passes through the connecting hole 201 and extends into the interior of the structural box 2. The fixing groove 203 is opened on the front and rear sides of the connecting column 202. The circular shaft 204 is fixedly connected to the interior of the structural box 2. The gear ring 205 is sleeved on the surface of the circular shaft 204. The gear members 206 are meshed and connected to both sides of the gear ring 205. The connecting plates 207 are respectively fixedly connected to one end of the gear members 206. One end of the fixing block 208 is respectively fixedly connected to the inner side of the connecting plate 207. The other end of the fixing block 208 penetrates into the interior of the fixing groove 203. One end of the compression spring 209 is fixedly connected to the inner wall of the structural box 2, and the other end of the compression spring 209 is fixedly connected to the outer side of the connecting plate 207. A pulling plate 5 is fixedly connected to the top of the front connecting plate 207. The pulling plate 5 penetrates to the top of the structural box 2. When the staff needs to connect two pipes 1, first align the flange rings of the pipes 1, then put the clamping ring 101 on the flange rings of the pipes 1, and then insert the connecting column 202 at one end of the flange ring into the interior of the structural box 2 through the connecting hole 201. When the staff needs to connect two pipes 1, first align the flange rings of the pipes 1, then put the clamping ring 101 on the flange rings of the pipes 1, and then insert the connecting column 202 at one end of the clamping ring 101 into the interior of the structural box 2 through the connecting hole 201. At the same time, the staff pulls the front connecting plate 207 outward through the pulling plate 5. The outward movement of the connecting plate 207 can drive the gear member 206 on the connected side to move outward. After one side of the gear member 206 moves outward, it can drive the meshed gear ring 205 to rotate on the surface of the circular shaft 204. At the same time, the gear ring 205 will drive the meshed gear member 206 on the other side to also move outward. When the gear members 206 move outward simultaneously, they can drive the fixing block 208 to move outward through the connecting plate 207 and squeeze the compression spring 209. Then, after the connecting column 202 is inserted into the interior of the structural box 2, the clamping ring 101 is pressed tightly. Then, release the hand from the pulling plate 5, and the compression spring 209 can push the connecting plate 207 and the fixing block 208 to move inward simultaneously under the rebound force. Reverse the above steps to make the fixing block 208 cooperate with the fixing groove 203 and fix and limit the connecting column 202 in the interior of the structural box 2 under the rebound force of the compression spring 209. At the same time, the clamping ring 101 can be stably clamped at the connection of the pipe 1, so that the pipe 1 can be quickly connected, improving the efficiency of the staff in connecting the pipe 1. And when the staff needs to disassemble and maintain the pipe 1, they can reverse the above steps to disassemble the pipe 1, reducing the maintenance time and improving the maintenance efficiency of the pipe 1;
[0022] Please refer to Figures 2-3, sliding members 301 are fixedly connected to the tops of the tooth members 206. A slide bar 302 is fixedly connected inside the structure box 2. The sliding members 301 are respectively fixedly connected to the surface of the slide bar 302. When the tooth members 206 move, the tooth members 206 will drive the sliding members 301 to slide flexibly on the surface of the slide bar 302, and can assist in limiting the tooth members 206, so that the tooth members 206 move in a left parallel manner, avoiding displacement of the tooth members 206 during movement and detachment from the tooth ring 205, and affecting the normal operation of the clamping mechanism.
[0023] Please refer to Figures 2-3 , a telescopic rod 4 is movably arranged inside the compression spring 209. One end of the telescopic rod 4 is fixedly connected to the outside of the connecting plate 207, and the other end of the telescopic rod 4 is fixedly connected to the inside of the structure box 2. When the connecting plate 207 squeezes the compression spring 209, a stable support point can be provided inside the compression spring 209 to ensure that the compression spring 209 maintains linear motion during compression and extension, avoiding deflection or bending. At the same time, under the action of the relatively two compression springs 209 and the telescopic rod 4, its flexibility can be improved, and the connecting plate 207 and the fixing block 208 can be pushed more stably, so that the fixing block 208 and the fixing groove 203 can be connected more firmly.
[0024] Please refer to Figure 1 , a mating groove 6 is formed at the top of the structure box 2. The pull plate 5 is slidably connected inside the mating groove 6. When the pull plate 5 is pulled, the pull plate 5 can slide flexibly inside the mating groove 6, and avoid collision between the pull plate 5 and the structure box 2 due to insufficient space during movement, which affects the operation of the clamping mechanism.
[0025] Please refer to Figures 2-3 , a stop block 7 is fixedly connected to the end of the tooth member 206. The shape of the stop block 7 is circular. When the tooth member 206 moves outward, in order to prevent the tooth member 206 from moving too far and disengaging from the engaged tooth ring 205, the stop block 7 can prevent the tooth member 206 from disengaging from the tooth ring 205.
[0026] Please refer to Figures 2-4 , the number of the fixing grooves 203 is several and they are evenly distributed on the front side and the rear side of the connecting column 202. Under the action of the multiple fixing grooves 203, the clamping mechanism can be flexibly adjusted according to the diameters of the pipeline 1 and the flange, so as to be able to connect and fix different pipelines 1, improving the practicality and wide applicability of the clamping mechanism.
[0027] Working principle: When the staff needs to connect two pipes 1, first align the flange rings of the pipe 1, then put the clamping ring 101 on the flange ring of the pipe 1. Subsequently, insert the connecting column 202 at one end of the clamping ring 101 into the interior of the structure box 2 through the connecting hole 201. At the same time, the staff pulls the front connecting plate 207 outward through the pulling plate 5. The outward movement of the connecting plate 207 can drive the tooth part 206 on the connecting side to move outward. After one side of the tooth part 206 moves outward, it can drive the meshing tooth ring 205 to rotate on the surface of the round shaft 204. At the same time, the tooth ring 205 will drive the meshing tooth part 206 on the other side to also move outward. When the tooth parts 206 move outward simultaneously, they can drive the fixing block 208 to move outward through the connecting plate 207 and squeeze the compression spring 209. Subsequently, after the connecting column 202 is inserted into the interior of the structure box 2, the clamping ring 101 is pressed tightly. Then, when the hand is removed from the pulling plate 5, the connecting plate 207 and the fixing block 208 can be pushed to move inward simultaneously under the rebounding force of the compression spring 209. Reverse the above steps to make the fixing block 208 fit and connect with the fixing groove 203, and fix and limit the connecting column 202 in the interior of the structure box 2 under the rebounding force of the compression spring 209. At the same time, the clamping ring 101 can be stably clamped at the connection of the pipe 1. Thus, with the mutual cooperation of the clamping mechanism, the pipe 1 can be quickly connected, improving the efficiency of the staff in the connection construction of the pipe 1.
