Abstract
The invention relates to an anti-dust device of a mast type lifting mechanism. The anti-dust device comprises dust-proof covers respectively and fixedly arranged on each lifting ejection rod, wherein multiple dust-proof covers are in a stepped shape when the lifting mechanism lifts, a previous dust-proof cover can cover an opening formed in the upper ejection rod where a next dust-proof cover is located, the multiple dust-proof covers are spliced to form a cover plate when the lifting mechanism is taken up, and the openings formed in the upper ends of the lifting ejection rods are covered. Fallen dust is decreased through the dust-proof covers of the anti-dust device, the service life of the lifting mechanism is prolonged, meanwhile tools or parts can be effectively prevented from falling, and probability of safety accident occurrence can be reduced.
Description
Technical field
The present invention relates to a kind of dust guard of column type elevating mechanism.
Background technology
Column type elevator, is widely used in the places such as factory, hotel, dining room, station, airport cinema, exhibition center, is to protect
The best safety companion of the purposes such as foster equipment, paint finishing, exchange light fixture, electrical equipment, cleaning maintenance, also very common on market,
But in escalation process, its flexible push rod is to step up or decline, stretch gear used or the driving-chain of flexible push rod
Etc. being all disposed within inside lifting top rod, and flexible push rod upper end is unlimited, and dust or chip easily fall in flexible push rod
Portion, reduces the service life of gear assembly, meanwhile, after instrument or part surprisingly fall in flexible push rod, directly stuck gear,
Easily cause the generation of contingency.
Content of the invention
The technical problem to be solved is to overcome the deficiencies in the prior art, provides a kind of improved column type lifting
The dust guard of mechanism.
For solving above-mentioned technical problem, the present invention adopts the following technical scheme that:
A kind of dust guard of column type elevating mechanism, it includes the screening dirt being respectively fixedly disposed on every lifting top rod
Lid, when elevating mechanism rises, multiple dust proofs are stepped, and can be located at next screening dirt positioned at a upper dust proof
The opening masking of the lifting top rod upper end that lid is located, when elevating mechanism draws in, multiple dust proofs are spliced into one piece of cover plate, will be every
The upper end open masking of root lifting top rod.
Specifically, the both sides in lifting top rod are provided with connecting portion, and dust proof is detachably connected with connecting portion, and hide dirt
Lid includes the screening dirt portion of horizontal-extending setting.
Further, hide dirt portion and be provided with notch part and protuberance, when elevating mechanism rises, positioned at a upper dust proof
Protuberance by positioned at next dust proof notch part masking, when elevating mechanism draws in, in two often adjacent dust proofs
A protuberance and another dust proof notch part splicing, and the upper end open masking by every lifting top rod.
Specifically, the material of dust proof is rubber.
Due to the enforcement of above technical scheme, the present invention compared with prior art has the advantage that
The setting by dust proof for the present invention, reduces falling into of dust, extends the service life of elevating mechanism, can also simultaneously
Enough it is effectively prevented falling into of instrument or part, reduce the probability that security incident occurs.
Brief description
The present invention will be further described in detail with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the perspective view (elevating mechanism is in raised configuration) of the dust guard according to the present invention；
Fig. 2 is the perspective view (elevating mechanism is in rounding state) of the dust guard according to the present invention；

Specific embodiment
As depicted in figs. 1 and 2, according to the dust guard of the column type elevating mechanism of the present embodiment, it includes fixing respectively
It is arranged on the dust proof 2 on every lifting top rod 1, when elevating mechanism rises, multiple dust proofs 2 are stepped, and be located at upper
The opening 10 of lifting top rod 1 upper end being located positioned at next dust proof 2 can be covered by one dust proof 2, works as elevating mechanism
During gathering, multiple dust proofs 2 are spliced into one piece of cover plate, and the upper end open 10 of every lifting top rod 1 is covered.
In order to realize the masking of above-mentioned opening 10, in this example, it is provided with connecting portion 11 in the both sides of lifting top rod 1, hide
Dirt lid 2 is detachably connected with connecting portion 11, and dust proof 2 includes the screening dirt portion 20 of horizontal-extending setting.
Further, hide dirt portion 20 and be provided with breach 20a portion and protuberance 20b, when elevating mechanism rises, positioned at upper one
Notch part 20a positioned at next dust proof 2 is covered by the protuberance 20b of individual dust proof 2, when elevating mechanism draws in, every phase
One of two adjacent dust proofs 2 protuberance 20b is spliced with the notch part 20a of another dust proof 2, and every lifting is pushed up
The upper end open 10 of bar 1 is covered.
Specifically, in this example, the material of dust proof 2 is rubber or plastics.
Above the present invention is described in detail, its object is to allow the personage being familiar with this art will appreciate that this
The content of invention is simultaneously carried out, and can not be limited the scope of the invention with this, all spirit institutes according to the present invention
The equivalence changes made or modification, all should cover within the scope of the present invention.
