[0022] As a technical optimization scheme of the utility model, by setting a clamping mechanism 6, it can be used in conjunction with the clamping member 4. The clamping member 4 drives the round block 62 to move to the outside of the round sleeve 61, and the round block 62 drives the movable rod 63 and the inclined block 65 to move to the outside of the round sleeve 61 and squeeze the spring 64. The inclined block 65 is engaged and separated with the engaging block 73, thereby improving the disassembly efficiency of pipe 1 and pipe 2 2.
[0023] refer to Figure 3 The docking assembly 7 includes a circular plate member 71, which is fixedly sleeved on the surface of the pipe 1. The surface of the circular plate member 71 is fixedly connected with a positioning block 72, and the number of the positioning blocks 72 is several. The left side of the surface of the pipe 1 is fixedly connected with a mosaic block 73, and the number of the mosaic blocks 73 is several.
[0024] As a technical optimization solution of the utility model, a docking component 7 is provided, which can be used in conjunction with the positioning groove 10. The position of the pipeline is positioned by the positioning block 72 and the positioning groove 10. When the positioning block 72 contacts the positioning groove 10, the engaging block 73 contacts the inclined block 65, thereby improving the docking efficiency of the pipeline 1 and the pipeline 2 2.
[0025] refer to Figure 2 The inner wall of the clamping member 4 is C-shaped, and the inner side of the clamping member 4 is movably connected to the surfaces of the circular plate member 1 3 and the circular plate member 2 71 .
[0026] As a technical optimization scheme of the utility model, by setting a C-shaped setting, the inner wall of the clamping member 4 can clamp the surface of the circular plate member 1 3 and the circular plate member 2 71, so that the circular plate member 1 3 and the circular plate member 2 71 are further fixed, thereby improving the use effect of the circular plate member 1 3 and the circular plate member 2 71.
[0027] refer to Figure 2 The surface of the handle 5 is fixedly connected with an anti-slip sleeve 8, and the anti-slip sleeve 8 is located on the outside of the clamping member 4.
[0028] As a technical optimization solution of the present invention, by providing the anti-slip cover 8, the friction between the palm and the handle 5 can be increased when the operator pulls the handle 5, thereby improving the use effect of the handle 5.
[0029] refer to Figure 2 The left side of the pipeline 2 is fixedly connected with a sealing ring 9, and the left side of the sealing ring 9 is movably connected to the right side of the pipeline 1.
[0030] As a technical optimization solution of the present invention, by providing a sealing ring 9, the contact between pipe 1 and pipe 2 2 can be made more sealed, the sealing effect is further strengthened, and the sealing effect between pipe 1 and pipe 2 2 is improved.
[0031] refer to Figure 2 A positioning groove 10 is provided on the left side of the surface of the circular plate member 3 , and the positioning groove 10 is plug-connected with the positioning block 72 .
[0032] As a technical optimization solution of the utility model, by setting the positioning groove 10, it can be used in conjunction with the positioning block 72. By plugging the positioning block 72 into the positioning groove 10, pipe 1 and pipe 2 2 can be quickly docked, thereby improving the docking effect of pipe 1 and pipe 2 2.
[0033] The working principle and use process of the utility model are as follows: when in use, the clamping member 4 is pulled out from the surface of the circular plate member 1 3 and the circular plate member 2 71 through the handle 5, and the clamping member 4 drives the round block 62 to move to the outside of the circular sleeve 61, and the round block 62 drives the movable rod 63 and the inclined block 65 to move to the outside of the circular sleeve 61 and squeeze the spring 64, and the inclined block 65 is engaged and separated from the engaging block 73, pulling the pipe 1 to move to the side away from the pipe 2 2, and the pipe 1 drives the circular plate member 2 71, the engaging block 73, and the positioning block 72 to move to the left, so that the pipe 1 is separated from the pipe 2 2, which is convenient for cleaning the scale layer inside the pipe. When the pipe needs to be connected, the pipe 1 is pushed to the right side, and the pipe 1 drives the circular plate member 2 71, the engaging block 73, and the positioning block 72 to move to one side of the pipe 2 2. The block 72 is used to locate the position of the pipeline with the positioning groove 10. When the positioning block 72 is in contact with the positioning groove 10, the engaging block 73 is in contact with the inclined block 65, and the pipeline 1 and the pipeline 2 are in contact. The joint of the pipeline 1 and the pipeline 2 is sealed by the sealing ring 9. The surface of the engaging block 73 slides with the surface of the inclined block 65 and squeezes the inclined block 65. The inclined block 65 drives the movable rod 63 and the round block 62 to move to the outside of the circular sleeve 61. The round block 62 drives the clamping member 4 to slide to both sides with the circular plate member as the center. When the engaging block 73 is engaged with the inclined block 65, the spring 64 resets and drives the inclined block 65, the movable rod 63, the round block 62, and the clamping member 4 to reset and clamp the engaging block 73. The clamping member 4 clamps the surfaces of the circular plate member 1 3 and the circular plate member 2 71, clamps the pipeline, and completes the sealing of the pipeline.
[0034] In summary: the sealing connection structure of the heat exchanger, through the coordinated use of pipe 1, pipe 2, circular plate member 1, clamping member 1, handle 5, clamping mechanism 6 and docking assembly 7, solves the problem that when the existing heat exchanger is sealed on the pipe, bolts and nuts are usually used to make the connection sealed. After long-term use, a scale layer will be generated inside the pipe, resulting in a decrease in the heat exchange efficiency of the heat exchanger, and the pipe needs to be cleaned. When the bolts are disassembled, the disassembly time is long and the disassembly efficiency is poor, which reduces the efficiency of pipe maintenance and increases the time required for pipe disassembly.
