Abstract
The utility model discloses a kind of chain stretching device, comprise and connect the chain of gear, outside described chain, be provided with curved roof, curved roof projection one facing to chain, curved roof two ends end points line is parallel with chain feeding direction, and described curved roof both sides of the edge are provided with catch.The one side of described curved roof projection is smooth surface.Described curved roof is provided with two.Compared to prior art, chain stretching device structure of the present utility model is simple, easy to use, the securable chain when chain fluffs, and is provided with catch due to curved roof of the present utility model, so chain can not come off, ensures that Chain conveyer normally runs.
Description
Technical field
Chain is conventional a kind of transmission device, and the scope of application is very extensive.Chain is wound on sprocket wheel, chain is in operation, problem can be caused to get more and more due to the wearing and tearing of chain, sprocket wheel, due to chain stressed for a long time after can there is plastic deformation and then elongated, also can occur to jump tooth time serious, fall the phenomenon of chain thus cause transmission process to interrupt even have an accident.Chain after lax easily falls chain, and that falls chain frequently reduces working efficiency, too increases dangerous situation hidden danger, therefore carries out tensioning with regard to tension device to chain.Be use hitch roll to carry out tensioning to chain at present, but hitch roll does not have limit stoper, chain is still easy from slippage hitch roll.
Background technique
The utility model relates to transmission device, particularly chain stretching device.
Model utility content
In order to overcome above-mentioned defect, the utility model provides simple, the easy to use and chain stretching device of difficult drop-off of a kind of structure.
The utility model is achieved through the following technical solutions: chain stretching device, comprise the chain connecting gear, curved roof is provided with outside described chain, curved roof projection one facing to chain, curved roof two ends end points line is parallel with chain feeding direction, and described curved roof both sides of the edge are provided with catch.
The one side of described curved roof projection is smooth surface.
Described curved roof is provided with two.
The beneficial effects of the utility model: compared to prior art, chain stretching device structure of the present utility model is simple, easy to use, the securable chain when chain fluffs, and be provided with catch due to curved roof of the present utility model, so chain can not come off, ensure that Chain conveyer normally runs.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises and connects the chain 2 of gear 1, is provided with curved roof 3 in the outside of chain 2, curved roof 3 projection one facing to chain 2, the one side of curved roof 3 projection is smooth surface.
Curved roof 3 two ends end points line is parallel with chain 2 feeding direction.
In order to prevent chain from landing top board, be provided with catch 4 in top board 3 both sides of the edge.
In order to increase the tension effects of chain, can arrange curved roof 3 respectively in chain both sides, two curved roofs 3 improve the ability that prevention chain falls chain simultaneously.
