Preferably, the side of the lifting structure, the sliding rail is equipped with the rack gear.
Preferably, the lifting structure, the both ends of the nutted rod are equipped with retaining ring, the cooperation of two retaining rings,
For preventing the nutted rod from moving in lifting process along itself direction.
Preferably, the lifting structure, the retaining ring be deep groove ball bearing, and the nutted rod go up and down when, the depth
Ditch ball bearing can be rolled along the sliding rail.
Preferably, the outermost of the lifting structure, the nutted rod both ends is equipped with flat key.
A kind of tensioning apparatus, the tensioning apparatus include the lifting structure as described in above-mentioned any bar.
Lifting structure provided by the utility model, including nutted rod and two sliding rails；Wherein, the both ends of nutted rod are equipped with
Gear, two sliding rails are respectively placed in the both ends of nutted rod, are equipped with rack gear in each sliding rail；In actual use, two gear energy
It is enough meshed respectively with corresponding rack gear, the lifting to realize nutted rod.As shown in the above, this lifting structure is to pass through tooth
The cooperation of wheel and rack, to realize nutted rod lifting；Compared with the prior art the shape that the both ends of middle nutted rod are moved in sliding rail
For formula, this lifting structure can be avoided nutted rod sliding offset phenomena such as, guarantee the precision of paper feed.Therefore, this is practical
The lifting structure of novel proposition can be improved the precision of lifting structure paper feed, solve the problems, such as the field at this stage.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the schematic diagram of nutted rod in specific embodiment of the present invention；
Fig. 2 is the schematic diagram of sliding rail in specific embodiment of the present invention；
Fig. 3 is the schematic diagram that nutted rod is combined with sliding rail in specific embodiment of the present invention.
In Fig. 1-Fig. 3:
Nutted rod -1, gear -2, sliding rail -3, rack gear -4, retaining ring -5, flat key -6.
Specific embodiment
The core of present embodiment is to provide a kind of lifting structure, which can be improved lifting structure and walk
The precision of paper solves the problems, such as the field at this stage.
Hereinafter, being illustrated referring to attached drawing to embodiment.In addition, embodiments illustrated below is not to recorded in claim
Utility model content rise any restriction effect.In addition, the full content of composition represented by following example is not limited to conduct
Necessary to the solution of utility model documented by claim.
The lifting structure that present embodiment provides, referring to Figure 1-Fig. 3；Including nutted rod 1 and two sliding rails 3；Its
In, the both ends of nutted rod 1 are equipped with gear 2, and two sliding rails 3 are respectively placed in the both ends of nutted rod 1, are equipped in each sliding rail 3
Rack gear 4；In actual use, two gears 2 can be meshed respectively with corresponding rack gear 4, the lifting to realize nutted rod 1.By
Above content is it is found that this lifting structure is by the cooperation of gear 2 and rack gear 4, to realize what nutted rod 1 was gone up and down；It compares existing
For the form that the both ends of nutted rod are moved in sliding rail in technology, this lifting structure can be avoided the sliding offset of nutted rod 1
Phenomena such as, guarantee the precision of paper feed.Therefore, the utility model proposes lifting structure, can be improved lifting structure paper feed
