Through such a design, the device can easily and conveniently connect the modules that need to be connected, saving time and effort, and improving the convenience and practicality of the device.

[0023] A sealing mechanism 200 is provided between the lower clamping plate 110 and the upper clamping plate 111, and the sealing mechanism 200 is provided between the sub-frame module 120 and the end wall body 130. The sealing mechanism 200 includes a sealing shell 210, a first support block 211, a rotating disk 212, a screw rod 213, a second support block 215, a moving block 220, a pushing rod 221, a pushing block 222, a sealing spring 223, a sealing seat 224 and a sealing gasket 225. The top end of the lower clamping plate 110 is fixedly connected to the bottom end of the sealing shell 210, and the top end of the sealing shell 210 is fixedly connected to the bottom end of the upper clamping plate 111. The inside of the sealing shell 210 is fixedly connected to the first support block 211, the first support block 211 and the screw rod 213 are rotatably connected, and the end of the screw rod 213 away from the first support block 211 is connected to the second support block 2 15 is rotatably connected, one end of the screw rod 213 away from the second supporting block 215 is fixedly connected to the turntable 212, and the outer wall of the screw rod 213 is threadedly connected to the moving block 220, both sides of the moving block 220 are connected to the pushing rod 221, and the end of the pushing rod 221 away from the moving block 220 is rotatably connected to the side of the pushing block 222 close to the moving block 220, the inner wall of the pushing block 222 is fixedly connected to the sealing spring 223, and the end of the sealing spring 223 away from the moving block 220 is fixedly connected to the sealing seat 224, and the side of the sealing seat 224 away from the screw rod 213 is glued with a sealing gasket 225. Through such a design, there is no need to add an additional sealing structure, the device itself has a sealing structure, which reduces the difficulty of operation during installation, is simple and convenient to operate, and improves the practicability and sealing of the device.

[0024] The horizontal distance between the upper clamping plate 111 and the block 112 is slightly greater than the thickness of the end wall body 130. This design ensures that the end wall body 130 can be inserted between the upper clamping plate 111 and the block 112, thereby improving the practicability of the device.

[0025] The top and bottom ends of the moving block 220 are fixedly connected to the limiting rod 214, and the end of the limiting rod 214 away from the moving block 220 is embedded in the slide groove opened on the inner wall of the sealing shell 210. Through such a design, the moving block 220 is restricted when moving, ensuring that the moving block 220 itself will not rotate when moving along the sealing spring 223, and the device is more stable and sensitive during operation.

[0026] The sealing springs 223 are arranged in multiple groups, and the sealing springs 223 are evenly arranged between the pushing block 222 and the sealing seat 224. Such a design ensures that the sealing springs 223 can push the end wall body 130 to fit with the block 112 through the sealing seat 224 and the sealing gasket 225, and the sealing springs 223 can exert a greater force on the sealing gasket 225, so that the sealing gasket 225 can maintain a close fit with the surface of the sub-frame module 120 and the end wall body 130, thereby improving the sealing and firmness of the device.

[0027] The sealing gasket 225 is configured to have a semicircular cross-section, and the sealing gasket 225 is configured in multiple groups. Through such a design, the sealing gasket 225 fits more tightly against the surface of the sub-frame module 120 and the end wall body 130 close to the sealing mechanism 200, thereby improving the sealing performance of the device.

[0028] Working principle: When it is necessary to connect the sub-frame module 120 and the end wall body 130, insert the sub-frame module 120 between the lower clamping plate 110 and the upper clamping plate 111, then rotate the fixing bolt 115 to fix the lower clamping plate 110 and the upper clamping plate 111 at the right end of the sub-frame module 120, then pull out the positioning pin 113, after pulling out the positioning pin 113, insert the end wall body 130 between the upper clamping plate 111 and the block 112 until the end wall body 130 fits with the top of the lower clamping plate 110, then release the positioning pin 113, and the positioning pin 113 returns to its original position under the action of the positioning spring 114. At this time, the right end of the positioning pin 113 is embedded in the groove inside the end wall body 130, and the sub-frame module 120 and the end wall body 130 are connected, and the operation ends here.

[0029] After the sub-frame module 120 and the end wall body 130 are connected by the device, the turntable 212 is rotated, and the rotation of the turntable 212 drives the screw rod 213 to rotate. The rotating screw rod 213 drives the moving block 220 to move through the surface thread. When the moving block 220 moves, it drives the push rod 221. The push rod 221 pushes the push block 222 to move away from the moving block 220. When the push block 222 moves, it drives the sealing spring 2233, the sealing seat 224 and the sealing gasket 225 to move away from the moving block 220. The moving block 220 moves in the direction until the sealing gasket 225 contacts the right side of the sub-frame module 120 and the left side of the end wall body 130, and then the turntable 212 continues to rotate, the sealing spring 223 is deformed by the force, and squeezes the sealing gasket 225 to fit the side of the sub-frame module 120 and the end wall body 130 close to the moving block 220, and the end wall body 130 is pushed by the sealing gasket 225 to fit the side of the block 112 close to the moving block 220, and the operation ends here.
