Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides the dustproof bearing based on the activated carbon, and dust entering the bearing can be adsorbed and cleaned by the adsorption effect of the activated carbon, so that the effective dustproof effect is achieved.

Technical proposal

The utility model provides a dustproof bearing based on active carbon, includes pivot and bearing, the fixed connection housing that is provided with in both sides of bearing, be provided with first perforation on the connection housing, the pivot runs through first perforation and not with the connection housing contact, the connection housing keep away from be provided with first splice groove in the one side surface of bearing, two fixed sleeves of position symmetry still fixedly connected with in the pivot, fixed sleeve is last detachable fixed mounting has a plurality of to block the disc, it is provided with the active carbon layer that one deck was used for removing dust on the surface to block the disc, still be provided with on the connection housing with block the safety cover mechanism of disc correspondence quantity, safety cover mechanism include the zonulae occludens in first splice groove, the zonal one end fixedly provided with safety cover of connection housing is kept away from to the go-between, be provided with the second splice groove in one side of connection housing in the safety cover, still be provided with on the safety cover can by the second perforation that the pivot runs through.

Further, the protection cover is not contacted with the active carbon layer, a fine channel is reserved between the protection cover and the active carbon layer, the rotation of the rotating shaft is not affected due to the existence of the fine channel, and dust in air in the fine channel can be adsorbed by the active carbon layer, so that the dustproof effect of the bearing is achieved.

Furthermore, the second splicing groove can be matched with and tightly connected with the connecting ring.

Furthermore, the number of the blocking discs and the number of the protecting covers are two, and if the use environment is worse, the number of the blocking discs and the number of the protecting covers can be increased.

Further, the fixed sleeve and the rotating shaft are sealed.

Advantageous effects

Compared with the prior art, the invention has the following beneficial effects: due to the reason that the bearing rotates, gaps exist in the sealing structure of the bearing, dust is introduced into the sealing structure, and the dust introduced into the bearing can be adsorbed and cleaned through the adsorption effect of the activated carbon, so that the effective dustproof effect is achieved.

fig. 2 is an enlarged view at a in fig. 1.

Reference numerals and signs

The device comprises a rotating shaft 1, a bearing 2, a connecting housing 3, a fixed sleeve 4, a blocking disc 5, an activated carbon layer 6, a second perforation 7, a protective cover 8, a second splicing groove 9, a connecting ring 10, a first perforation 11, a first splicing groove 12 and a micro channel 13.

Detailed Description

For a better illustration of the present invention, the following description is made with reference to the accompanying drawings and examples:

the invention discloses an active carbon-based dustproof bearing, which comprises a rotating shaft 1 and a bearing 2, wherein a connecting housing 3 is fixedly arranged on two sides of the bearing 2, a first through hole 11 is formed in the connecting housing 3, the rotating shaft 1 penetrates through the first through hole 11 and is not in contact with the connecting housing 3, a first splicing groove 12 is formed in one side surface of the connecting housing 3 far away from the bearing 2, two fixing sleeves 4 which are symmetrical in position are fixedly connected to the rotating shaft 1, a plurality of blocking discs 5 are detachably and fixedly arranged on the fixing sleeves 4, a layer of active carbon layer 6 used for dust removal is arranged on the surface of the blocking discs 5, a protective cover mechanism which corresponds to the blocking discs 5 is further arranged on the connecting housing 3, the protective cover mechanism comprises a connecting ring 10 which is tightly connected with the first splicing groove 12, a protective cover 8 is fixedly arranged at one end of the connecting ring 10 far away from the connecting housing 3, a second through hole 9 which can be penetrated by the rotating shaft 7 is further arranged in one side surface of the protective cover 8 far away from the connecting housing 3.

Further, the protection cover 8 is not in contact with the activated carbon layer 6, and a fine channel 13 is reserved between the protection cover 8 and the activated carbon layer 6, the rotation of the rotating shaft 1 is not affected by the existence of the fine channel 13, and dust in the air in the fine channel 13 can be adsorbed by the activated carbon layer 6, so that the dust-proof effect of the bearing 2 is achieved.
