[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] The existing technology has the problem of low sealing performance of the sealed box. This embodiment provides a high-performance sealed box, which can improve the sealing performance of the sealed box. Please refer to Figures 1-4 This high-performance sealed box includes a worm gear 2 rotatably connected to the interior of the sealed box 1, and a worm 3 rotatably connected to the interior of the sealed box 1 and meshing with the worm gear 2. A support mechanism 4 is provided within the sealed box 1 to ensure stable rotation of the worm gear 2. A sealing mechanism 5 is also provided within the sealed box 1 to improve the sealing performance of the sealed box 1. The support mechanism 4 stably supports the worm gear 2, allowing it to rotate stably. The sealing mechanism 5 not only allows for quick assembly and disassembly of the box cover 51, but also utilizes multiple sets of sealing rings to seal the sealed box 1, thereby improving the sealing effect.

[0025] During the use of the sealing box 1, in order to improve the sealing performance of the sealing box 1 and prevent dust and debris from entering the sealing box 1, the sealing mechanism 5 includes a sealing plate 54 installed inside the sealing box 1, and a positioning column 55 is fixedly installed at the bottom end of the sealing plate 54. The positioning columns 55 are symmetrically distributed in pairs at the bottom end of the sealing plate 54, so that the sealing disc 57 can move more stably. The outer wall of the positioning column 55 is connected to a buffer spring 56, and the outer wall of the positioning column 55 is connected to a sealing disc 57 connected to one end of the buffer spring 56. Several groups of sealing rings 58 are installed on the outer wall of the disk 57. The material of the sealing rings 58 is made of waterproof rubber material, which prolongs the sealing time of the device. Several groups of sealing circular grooves 59 are opened on the inner side of the sealing plate 54, which are compatible with the sealing rings 58. A rotating rod 510 is rotatably connected to the inside of the sealing box 1. A turning handle 511 is fixedly installed on one end of the rotating rod 510, and a top piece 512 is fixedly installed on the outer wall of the rotating rod 510 to abut the bottom end of the sealing disk 57. The sealing box 1 is provided with a fitting component 501 for sealing the top end of the sealing box 1. By turning the turning handle 511, the rotating rod 510 is rotated, and the top piece 512 pushes the sealing disk 57 upward. Under the connection of the buffer spring 56, it has a certain degree of ductility. When the sealing disk 57 moves upward, the sealing ring 58 is engaged with the sealing circular groove 59, thereby playing a double sealing role and improving the sealing performance of the device.

[0026] In order to quickly disassemble and assemble the box cover 51 and to preliminarily seal the sealed box 1, the fitting assembly 501 includes a box cover 51 movably mounted on the top of the sealed box 1. The box cover 51 is connected to the top of the sealed box 1 via a fixing bolt 52, making it easy to quickly install the box cover 51 on the top of the sealed box 1. The fixing bolt 52 is threadedly connected to the box cover 51. A pressure plate 53 is mounted on the bottom of the box cover 51 to abut against the top of the sealing plate 54. The area of ​​the bottom of the pressure plate 53 is larger than the area of ​​the top of the sealing disc 57, which facilitates better sealing of the interior of the sealed box 1 and improves the sealing performance. The box cover 51 is first closed on the top of the sealed box 1 so that the pressure plate 53 abuts against the top of the sealing plate 54, and then the box cover 51 is fixed to the top of the sealed box 1 via the fixing bolt 52, thereby achieving a preliminary sealing effect on the sealed box 1.

[0027] Example 2

[0028] Based on Example 1, Figures 1-4 As shown, based on the problem of low sealing performance of the sealing box 1 in the existing prior art, when the worm gear 2 inside the traditional sealing box 1 rotates, the worm gear 2 is driven to rotate only by the rotation of the worm 3, which easily affects the rotation stability of the worm gear 2. Therefore, the device is also provided with a structure that makes the rotation of the worm gear 2 more stable.

[0029] During the rotation of the worm gear 2, in order to make its rotation more stable, the support mechanism 4 includes a fixed plate 41 mounted on the worm gear 2 and a support seat 46 mounted inside the sealed box 1. The top of the fixed plate 41 is fixedly mounted with an L-shaped plate 42, and the side of the L-shaped plate 42 is provided with a rotation groove 43. The rotation groove 43 is internally connected to a mounting block 44. One end of the mounting block 44 is fixedly mounted with a support wedge 45. The support wedge 45 is distributed in a triangular shape inside the circular support groove 47, so that the support wedge 45 always fits with the inside of the circular support groove 47 and is not easily separated, thereby further improving the rotation stability of the worm gear 2. The support wedge 45 fits tightly with the inside of the circular support groove 47, making the support wedge 45 rotate more smoothly. The inner side of the support seat 46 is provided with a circular support groove 47 that is compatible with the support wedge 45. During the rotation of the worm gear 2, under the connection of the fixed plate 41, the support wedge 45 rotates along the inside of the circular support groove 47, thereby playing a role in rotating the worm gear 2.
