[0026] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an independent or selectively mutually exclusive embodiment with other embodiments.

[0029] Embodiment 1

[0030] Referring to Figures 1 to 6 , which is the first embodiment of the present utility model. This embodiment provides a connection structure between a thick-walled tube sheet and a shell, including an installation shell 100. Clamping blocks 200 are movably sleeved at both ends of the outer wall of the installation shell 100. A fixing rod 300 is fixedly connected to the side of the clamping blocks 200 close to each other. An adjusting block 400 is fixedly connected to the middle end of the fixing rod 300. Bidirectional threaded lead screws 500 are threadedly connected to both sides of the adjusting block 400. A plurality of fixing grooves 1100 are formed inside the clamping blocks 200. A spring telescopic tube 700 is fixedly connected to the inner cavity of the fixing grooves 1100. One end of the spring telescopic tube 700 away from the bottom surface of the inner cavity of the fixing grooves 1100 is fixedly connected to a moving block 800. A hole corresponding to the moving block 800 is formed in the side of the installation shell 100 close to the moving block 800. The tube sheet body 900 is movably clamped through the hole by the moving block 800.

[0031] The connection between the clamping blocks 200 and the fixing rod 300 limits the clamping blocks 200 to prevent the clamping blocks 200 from falling off the surface of the installation shell 100. By setting the fixing rod 300, the adjusting block 400 and the bidirectional threaded lead screws 500 to cooperate with each other, when the bidirectional threaded lead screws 500 rotate, they can drive the adjusting block 400 to move synchronously in the same or opposite directions, and then the adjusting block 400 drives the clamping blocks 200 to move synchronously towards or away from each other to clamp and release the installation shell 100. By setting the hole, it prevents the moving block 800 from being blocked and affecting the operation of the mechanism. By setting the spring telescopic tube 700 and the moving block 800, the tube sheet body 900 can be clamped by the spring telescopic tube 700 and the moving block 800 during installation, thereby realizing quick installation.

[0032] Embodiment 2

[0033] Referring to Figures 2 to 6, which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment. The fixing groove 1100 is set in a shape where a circle and a rectangle overlap. Both the fixing rod 300 and the adjusting block 400 are provided with two and are symmetric to each other. The inner cavity wall of the mounting housing 100 is fixedly connected with a baffle 1000. The baffle 1000 is movably connected with the tube sheet body 900. The moving block 800 is set in a trapezoidal shape and its surface is smooth. Both ends of the inner side of the mounting housing 100 are movably sleeved with the tube sheet body 900. A rectangular hole corresponding to the moving block 800 is opened on the outer surface of the tube sheet body 900, and the rectangular hole is movably clamped with the moving block 800.

[0034] By setting the fixing groove 1100 in a shape where a circle and a rectangle overlap, the structures can fit with each other, making it more stable during movement. By setting both the fixing rod 300 and the adjusting block 400 to two, the connection relationship between the structures is deepened, thereby strengthening the structural compactness and reducing the failures that occur during the use of the mechanism. By setting the baffle 1000, the tube sheet body 900 can be limited during installation to prevent the failure of installing the tube sheet body 900. By setting the moving block 800 in a trapezoidal shape, the tube sheet body 900 can be directly pushed into the inner cavity of the mounting housing 100 for portable installation. By setting the surface of the moving block 800 to be smooth, the resistance during the installation of the tube sheet body 900 is reduced and it can be more labor-saving. By setting the rectangular hole, the tube sheet body 900 can be clamped by the spring telescopic tube 700 and the moving block 800 during installation to achieve the installation.

[0035] Embodiment 3

[0036] Refer to Figures 1 to 6 , which is the third embodiment of the present utility model. This embodiment is based on the previous embodiment. The outer side of the moving block 800 is movably connected with the hole opened on the mounting housing 100. The inner side of the mounting housing 100 and the surface of the tube sheet body 900 are smooth. The inner side of the adjusting block 400 is movably connected with the outer surface of the mounting housing 100, and the sizes on both sides of the adjusting block 400 are the same. One end of the double-threaded lead screw 500 is fixedly connected with an adjusting handle 600. The end of the double-threaded lead screw 500 far from the adjusting handle 600 is fixedly connected with a round block. A spring is arranged on the outer side of the middle end of the double-threaded lead screw 500, and both ends of the spring are respectively fixedly connected with one side of the adjusting block 400.

[0037] By setting the movable block 800 to be movably connected to the hole, the movable block 800 can be limited, preventing the movable block 800 from shifting and affecting the operation of the structure. By setting the inner side of the mounting housing 100 and the surface of the tube sheet body 900 to be smooth, the frictional force during the installation of the tube sheet body 900 can be reduced, making it more labor-saving. By setting the cooperation relationship between the adjustment block 400 and the mounting housing 100, the adjustment block 400 can be prevented from falling off during movement. By setting the sizes of the adjustment blocks 400 to be consistent, the error during the synchronous opposite movement of the adjustment blocks 400 can be reduced, thereby enhancing the precision of clamping. By setting the adjusting handle 600, a person can control the adjusting handle 600 to rotate the double-threaded lead screw 500 for clamping and releasing. By setting the round block, the adjustment block 400 can be limited to prevent it from falling off. By setting the spring, the adjustment block 400 can be stressed, making the adjustment block 400 more stable when making synchronous opposite or separating movements.
