[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] See also Figures 1 to 7 In an embodiment of the present invention, a fixed sealing structure for connecting the inner and outer connecting pipes of a cooling protective suit includes an inner pipe 1 for connecting to a cooling air conditioner and an outer pipe 2 for connecting to a protective suit. Both ends of the inner pipe 1 and the outer pipe 2 are provided with a connecting assembly 4. The connecting assembly 4 includes two joint pipes 41, two sealing disks 42 and two first docking posts 43. The joint pipe 41 is slidably connected to the inner pipe 1 and the outer pipe 2. One side of one sealing disk 42 is fixedly connected to two second docking posts 46. The first docking post 43 on the inner pipe 1 is opposite to the second docking post 46 on the external pipe 2, and the second docking post 46 on the inner pipe 1 is opposite to the first docking post 43 on the external pipe 2.

[0029] The spherical shape of the inner and outer pipes 1 and 2 is convenient for operation. When the pipes are connected to the inner and outer pipes 1 and 2, the first and second connecting posts 43 on the inner and outer pipes 1 and 2 are connected, and the second and second connecting posts 46 on the outer and inner pipes 2 are connected. When the inner and outer pipes 1 and 2 are brought close to each other, the joint pipe 41 on the first and second connecting posts 43 and 46 on the outer and inner pipes 2 are connected. Under the action of the collision of the two docking columns 46, they can be exposed from the inner and outer pipes 1 and 2, so that the concave surfaces 8 relative to the inner and outer pipes 1 and 2 are fitted, and the locking block 441 is locked in the inner and outer pipes 1 and 2, and the pipe is inserted into the joint pipe 41 for use. The joint pipe 41 slides in the pipe limit seat 3, and one side of the pipe limit seat 3 is fixedly connected with two insertion sleeves 31, which are located in the inner and outer pipes 1 and 2, so that the joint pipe 41 can slide along the inner and outer pipes 1 and 2. The joint tube 41 is provided with an insertion section 411 for inserting the tube, and the sealing disk 42 is fixedly connected to one side of the insertion section 411 with two elastic positioning rods 45. The elastic positioning rods 45 are slidably connected to the insertion sleeve 31, and the elastic positioning rods 45 are connected to the insertion sleeve 31 by means of a spring. At the same time, when the joint tube 41 moves, the elastic positioning rods 45 can slide in the insertion sleeve 31 to position the position of the joint tube 41, and the elastic positioning rods 45 can be driven by the spring to reset the joint tube 41.

[0030] The sealing disk 42 is fixed to one end of the joint tube 41, and the two first docking posts 43 are fixedly connected to the sealing disk 42, one end of one of the first docking posts 43 is fixedly connected to a docking sleeve 44, and a snap-fit ​​fixing block 441 is slidably connected in the docking sleeve 44, and the docking sleeve 44 has an inner cavity for installing the snap-fit ​​fixing block 441, and the snap-fit ​​fixing block 441 is connected in the docking sleeve 44 through a limit spring 442, and the snap-fit ​​fixing block 441 on the inner tube 1 is snap-fitted to the outer tube 2, and the snap-fit ​​fixing block 441 on the outer tube 2 is snap-fitted to the inner tube 1, and both the inner tube 1 and the outer tube 2 are provided with an outer portion corresponding to the snap-fit ​​fixing block 441 When the first docking post 43 and the second docking post 46 move, the engaging and fixing block 441 on the docking sleeve 44 exceeds the inner cavity of the internal tube 1 or the external tube 2. When it contacts the end face of the internal tube 1 or the external tube 2, the engaging and fixing block 441 has a guiding inclined surface and can be squeezed and located in the docking sleeve 44, so that the engaging and fixing block 441 can move along the inner wall of the internal tube 1 or the external tube 2. When it is opposite to the external groove 7, the engaging and fixing block 441 is engaged with the external groove 7 under the action of the limit spring 442, so that the internal tube 1 and the external tube 2 can be connected to each other and fixed to each other for use.

[0031] The inner cavities of the joint pipe 41, the internal pipe 1 and the external pipe 2 form two flow cavities 6 for water inlet and water return, that is, one flow cavity 6 is a water inlet pipe, and the other flow cavity 6 is a water return pipe. The pipe is inserted into the insertion section 411 for use, and the end of the pipe can be pressed against the end face of the pipe limit seat 3 to limit the position.

[0032] The first docking post 43 on the internal tube 1 is inserted into the second docking post 46 on the external tube 2, and the second docking post 46 on the internal tube 1 is inserted into the first docking post 43 on the external tube 2, forming four plug-in cavities. Magnets are provided in the plug-in cavities. The first docking post 43 and the second docking post 46 cooperate with each other to locate the positions of the internal tube 1 and the external tube 2, and through magnetic adsorption, the positions of the internal tube 1 and the external tube 2 can be further stabilized.

[0033] A sealing rubber 5 corresponding to the joint pipe 41 is fixedly connected to the pipe limit seat 3. The sealing rubber 5 is composed of several sealing strips. When the inner and outer connecting pipes need to be separated, the inner pipe 1 and the outer pipe 2 can be moved outward by pressing the locking fixing block 441. If the pipeline leaves the joint pipe 41, the joint pipe 41 can be retracted into the inner pipe 1 and the outer pipe 2 under the action of the elastic positioning rod 45. When the joint pipe 41 extends out of the pipe limit seat 3, or is located in the inner pipe 1 and the outer pipe 2, the sealing rubber 5 can be used to drive the sealing rubber 5 to move. When the joint pipe 41 is located in the inner pipe 1 and the outer pipe 2, the sealing rubber 5 can limit the port position of the joint pipe 41, thereby achieving sealing and protection of the joint pipe 41.

[0034] like Figure 1-Figure 7 As shown, the present invention also provides a method for using the fixed sealing structure of the inner and outer connecting pipes of the cooling protective clothing, and the specific steps are as follows:

[0035] A: When the pipeline is connected to the internal pipe 1 and the external pipe 2, the first docking post 43 on the internal pipe 1 and the second docking post 46 on the external pipe 2 are docked, and the second docking post 46 on the internal pipe 1 and the first docking post 43 on the external pipe 2 are docked. The internal pipe 1 and the external pipe 2 are brought closer together. The joint pipe 41 can be exposed from the internal pipe 1 and the external pipe 2 due to the collision between the first docking post 43 and the second docking post 46. The concave surfaces 8 of the internal pipe 1 and the external pipe 2 are abutted, and the engaging and fixing block 441 is engaged with the internal pipe 1 and the external pipe 2. The pipeline is inserted into the joint pipe 41 for use.

[0036] B: When it is necessary to separate the inner and outer connecting pipes, the inner pipe 1 and the outer pipe 2 can be moved outward by pressing the locking fixing block 441. If the pipeline leaves the joint pipe 41, the joint pipe 41 can be retracted into the inner and outer pipes 1 and 2 under the action of the elastic positioning rod 45, thereby achieving sealing and protection of the joint pipe 41.

[0037] The working principle of the present invention is: by wearing the air-conditioning host, the pipeline of the refrigeration host can be connected to the protective clothing when in use, so as to realize the connection of the internal and external connecting pipes. By connecting the pipeline to the internal pipe 1 and the external pipe 2, the first docking post 43 on the internal pipe 1 and the second docking post 46 on the external pipe 2 are docked, and the second docking post 46 on the internal pipe 1 and the first docking post 43 on the external pipe 2 are docked. The first docking post 43 and the second docking post 46 cooperate with each other to position the position of the internal pipe 1 and the external pipe 2, and through magnetic adsorption, the position of the internal pipe 1 and the external pipe 2 can be further stabilized, and the internal pipe 1 and the external pipe 2 are brought close to each other, and the joint pipe 41 is at the first docking post 43 and the second docking post Under the action of the collision of 46, the joint tube 41 slides in the internal pipe 1 and the external pipe 2, and can be exposed from the internal pipe 1 and the external pipe 2, so that the relative concave surfaces 8 of the internal pipe 1 and the external pipe 2 are fitted together, and the locking and fixing block 441 moves along the inner walls of the internal pipe 1 and the external pipe 2, so that the locking and fixing block 441 is locked in the internal pipe 1 and the external pipe 2 to achieve a fixed connection. The pipeline is inserted into the joint tube 41 for use. When it is necessary to separate the inner and outer connecting pipes, the inner pipe 1 and the external pipe 2 can be moved outward by pressing the locking and fixing block 441, and if the pipeline leaves the joint tube 41, the joint tube 41 can be retracted into the internal pipe 1 and the external pipe 2 under the action of the elastic positioning rod 45, thereby achieving sealing and protection of the joint tube 41.

[0038] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
