[0024] Specifically, the sealing assembly 23 includes a sealing ring 231, a first protrusion 232 and a second protrusion 234. The sealing ring 231 is disposed inside the mounting groove 1 22, the second protrusion 234 is disposed on the side of the sealing ring 231, and the first protrusion 232 is disposed at the corner of the sealing ring 231.

[0025] By adopting the above technical solution, the sealing ring 231 is placed into the interior of the installation groove 22, so that the protrusions 232 and 234 on the side and corner of the sealing ring 231 are inserted into the corresponding positions inside the installation groove 22, and then the cover body 3 is fixed to the upper end of the turntable shell 1, thereby improving the sealing performance of the cover body 3 after installation.

[0026] Specifically, the sealing assembly 23 further includes a spring 235 and a mounting hole 236. The mounting hole 236 is provided inside the protrusion 234, and the spring 235 is provided inside the mounting hole 236.

[0027] By adopting the above technical solution, a mounting hole 236 is opened inside the protrusion 234, and a spring 1 235 is arranged inside the mounting hole 236. In this way, after the cover body 3 is installed, the cover body 3 will press down the sealing ring 231 and drive the spring 1 235 to compress, which will drive the sealing ring 231 to rebound, thereby improving the sealing effect of the cover body 3.

[0028] Specifically, a positioning rod 21 is provided at the inner corner of the installation groove 22, and a positioning hole 233 corresponding to the positioning rod 21 is provided inside the protrusion 232.

[0029] By adopting the above technical solution, when the sealing ring 231 is installed inside the installation groove 22, the positioning hole 233 inside the protrusion 232 on the side of the sealing ring 231 is correspondingly plugged into the positioning rod 21 inside the installation groove 22, thereby further improving the installation stability of the sealing ring 231.

[0030] When the present embodiment is in use, the sealing ring 231 is placed into the installation groove 22, so that the protrusions 1 232 and the protrusions 234 on the side and corners of the sealing ring 231 are inserted into the corresponding positions in the installation groove 22, and then the cover body 3 is fixed to the upper end of the turntable shell 1, thereby improving the sealing performance of the cover body 3 after installation. By opening a mounting hole 236 in the protrusion 234, a spring 1 235 is arranged inside the mounting hole 236. In this way, after the cover body 3 is installed, the cover body 3 will press down the sealing ring 231 and drive the spring 1 235 to compress, which will drive the sealing ring 231 to rebound, thereby improving the sealing effect of the cover body 3. When the sealing ring 231 is installed in the installation groove 22, the positioning hole 233 in the protrusion 1 232 on the side of the sealing ring 231 is correspondingly plugged into the positioning rod 21 in the installation groove 22, thereby further improving the installation stability of the sealing ring 231.

[0031] Example 2

The lower end side of the cover 3 is provided with a block 42, the side of the block 42 is provided with a fixing hole 41, the upper end side of the turntable housing 1 is provided with a slot 43 corresponding to the block 42, and the inside of the turntable housing 1 is provided with a fixing assembly 44 near the slot 43.

[0033] By adopting the above technical solution, the cover body 3 can be fixed by inserting the clamping block 42 at the lower end of the cover body 3 into the clamping groove 43 and then cooperating with the fixing assembly 44 and the fixing hole 41 .

[0034] Specifically, the fixing assembly 44 includes a handle 441, a pull rod 442, a second spring 443, a limit plate 444 and a fixed rod 445. A limit plate 444 is provided at a position near the slot 43 inside the turntable housing 1. A fixed rod 445 is provided on one side of the limit plate 444. A pull rod 442 is provided on the other side of the limit plate 444. A handle 441 is provided at the other end of the pull rod 442. A second spring 443 is provided on the surface of the pull rod 442.

[0035] By adopting the above technical solution, before installing the cover body 3, pull the handle 441, the handle 441 pulls the pull rod 442, the pull rod 442 pulls the limit plate 444 and the fixing rod 445, and drives the spring 2 443 to be compressed, and then the block 42 at the lower end of the cover body 3 is inserted into the interior of the slot 43, and the handle 441 is released, and the spring 2 443 rebounds, thereby driving the fixing rod 445 to be inserted into the interior of the fixing hole 41 to achieve fixed installation of the cover body 3.

[0036] When the present embodiment is in use, before installing the cover body 3, the pull handle 441 is pulled, the pull handle 441 pulls the pull rod 442, the pull rod 442 pulls the limit plate 444 and the fixing rod 445, and drives the spring 2 443 to be compressed, and then the block 42 at the lower end of the cover body 3 is inserted into the interior of the slot 43, and the pull handle 441 is released, and the spring 2 443 rebounds, thereby driving the fixing rod 445 to be inserted into the interior of the fixing hole 41, so as to achieve fixed installation of the cover body 3.

[0037] Working principle and use process of the utility model: When the utility model is in use, the sealing ring 231 is placed in the installation groove 22, so that the protrusions 232 and the protrusions 234 on the side and corner of the sealing ring 231 are inserted into the corresponding positions in the installation groove 22, and then the cover body 3 is fixed to the upper end of the turntable shell 1, so as to improve the sealing performance of the cover body 3 after installation. By opening a mounting hole 236 in the protrusion 234, a spring 235 is arranged in the mounting hole 236, so that after the cover body 3 is installed, the cover body 3 will press down the sealing ring 231 and drive the spring 235 to compress, which will drive the sealing ring 231 to rebound, thereby improving the sealing effect on the cover body 3. As a result, when the sealing ring 231 is installed in the installation groove 22, the positioning hole 233 in the protrusion 232 on the side of the sealing ring 231 is plugged into the positioning rod 21 in the installation groove 22, thereby further improving the installation stability of the sealing ring 231; before installing the cover body 3, pull the handle 441, the handle 441 pulls the pull rod 442, the pull rod 442 pulls the limit plate 444 and the fixing rod 445, and drives the spring 443 to compress, and then insert the block 42 at the lower end of the cover body 3 into the slot 43, release the handle 441, and the spring 443 rebounds, thereby driving the fixing rod 445 to insert into the fixing hole 41 to achieve fixed installation of the cover body 3.
