[0026] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-5As shown, the embodiment of the present invention provides a mechanical sealing device with a dustproof effect, including a base 1 and a mechanical seal 3, the mechanical seal 3 is fixedly installed on the top of the base 1, and a shaft 4 is movably connected in the inner cavity of the mechanical seal 3. A vertical plate 6 is fixedly installed on the right side of the top of the base 1. A protective mechanism 2 is provided on the top of the base 1. The protective mechanism 2 includes a micro motor 201 and a ring 203. The ring 203 is provided on the outside of the mechanical seal 3. A fixing rod 205 is fixedly installed on the top of the ring 203. The four fixing rods 205 are fixedly installed. 5 are movably connected to the other end of the four connecting rods 206, and the other ends of the four connecting rods 206 are movably connected to the mounting blocks 207. The outer sides of the four mounting blocks 207 are fixedly mounted with protective covers 208, and the four protective covers 208 are all fitted together. The micro motor 201 is fixedly mounted on the right side of the vertical plate 6, and the output end of the micro motor 201 is fixedly connected to the bevel gear 202. The bottom of the ring 203 is fixedly mounted with a bevel gear ring 204, and the surface of the bevel gear ring 204 is meshed with the surface of the bevel gear 202.

[0029] By setting up the protection mechanism 2, through the output of the micro motor 201, the ring 203 drives the fixed rod 205 to rotate, and through the cooperation of the fixed rod 205 and the connecting rod 206, the mounting block 207 pulls the protective cover 208 to move inward, thereby forming a sealed space at the position where the mechanical seal 3 is located. By protecting the mechanical seal 3, dust can be prevented from floating into the interior of the mechanical seal 3, and the mechanical seal 3 can be prevented from being damaged by the influence of dust, thereby extending the service life of the mechanical seal 3 and ensuring the stability of the use of the mechanical seal 3.

[0030] Example 2

[0031] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in one embodiment, the outer sides of the four protective covers 208 are each provided with an oblique angle 209, and the oblique angle 209 is a forty-five degree angle, the tops of the four protective covers 208 are each provided with an arc groove 210, and the shape of the four arc grooves 210 spliced ​​together is a circle, the top of the base 1 is provided with movable grooves 211, the bottoms of the four protective covers 208 are all slidably connected to the inner cavity of the eight movable grooves 211, the surface of the mechanical seal 3 is provided with a slide groove 212, the ring 203 is slidably connected to the inner cavity of the slide groove 212, the top of the base 1 is threadedly connected with a mounting bolt 5, the four mounting bolts 5 all penetrate the inner surface of the base 1 and extend to the bottom of the base 1, and a sealing ring 7 is fixedly installed on the top of the mechanical seal 3. The shape of the sealing ring 7 matches the shape of the four arc grooves 210, and the material of the sealing ring 7 is rubber.

[0032] By setting the bevel 209, since its angle is 45 degrees, the four protective covers 208 can be tightly fitted together when they are attached to each other, avoiding the existence of gaps when the protective covers 208 are attached, thereby preventing dust from floating into the inner cavity of the protective cover 208 through the gaps. By setting the arc groove 210, since its shape when attached to each other is circular and its size matches the size of the shaft body 4, it can reduce the gaps left when the protective cover 208 contacts the shaft body 4, thereby ensuring the dustproofness of the protective cover 208. By setting the movable groove 211, the protective cover 208 can be moved. The movement of the cover 208 is limited to avoid the offset of the protective cover 208 when it moves, thereby affecting the dust-proof effect of the mechanical seal 3. By setting the slide groove 212, the rotation of the ring 203 can be limited to avoid the offset of the ring 203 when it rotates, thereby affecting the splicing of the protective cover 208. By setting the mounting bolts 5, the overall installation of the equipment can be facilitated, thereby improving the convenience of the overall installation of the equipment. By setting the sealing ring 7, the mechanical seal 3 can be dust-proofed, reducing the damage of the mechanical seal 3 due to dust drifting in.

[0033] When the present invention is working: through the output of the micro motor 201, the bevel gear 202 rotates, and at this time the bevel gear 202 cooperates with the bevel gear ring 204 to make the ring 203 rotate. As the ring 203 rotates, the position of the fixing rod 205 changes, and pulls the connecting rod 206 to flip. At this time, the connecting rod 206 synchronously pulls the mounting block 207 and the protective cover 208 to move inward. At this time, the protective covers 208 fit together, so that a sealed space is formed on the outside of the mechanical seal 3. At the same time, as the protective cover 208 moves, the shaft body 4 fits into the inner cavity of the arc groove 210, thereby completing the dust-proof work of the mechanical seal 3.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
