Abstract
The utility model discloses a protection chain, inner plate, outer chain plate including the headtotail, inner plate or outer chain plate arrange the both sides at the roller in pairs, inner plate, outer chain plate, roller on leave the pinhole, through the assembly of round pin axle together, characterized by: inner plate or outer chain plate on stretch out and have the extension position, the extension position lie in inner plate or outer chain plate's top and bottom, the chain of structure can stop the drop meshing position of chain of foreign matter like this, has the advantage that operates steadily.
Description
Technical field
The utility model relates to drive technology field, the chain of specifically a kind of protection.
Background technique
In prior art, chain is applied on parking space widely as transmission part, chain-driving vehicle is driven to promote by sprocket wheel, due to the structural feature of link, dregs or linear foreign matter is easy to drop on the engagement position of link, causing the wearing and tearing person of link to be the fault of machine, there is the shortcoming that rate of fault is high, working life is short in the chain of this spline structure.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of protection chain that foreign matter enters chain engagement position that can stop
The utility model realizes by the following technical solutions: a kind of protection chain, comprise connected head-to-tail inner plate, outer plate, described inner plate or outer plate are arranged in the both sides of roller in pairs, described inner plate, outer plate, roller leave pin-and-hole, be assembled together by bearing pin, it is characterized in that: described inner plate or outer plate are extended with extending part, described extending part is positioned at top and the bottom of inner plate or outer plate.
In solution technique, be provided with fillet bottom described extending part, when preventing chain-loose, extending part is sagging pulls body.
The beneficial effects of the utility model are: the chain of this spline structure can stop that foreign matter drops the engagement position of chain, has the advantage operated steadily.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, inner plate 2, outer plate 3, roller 4 pin-and-hole 5, bearing pin 6, extending part 7, fillet.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As described in Figure 1, a kind of protection chain, comprise connected head-to-tail inner plate 1, outer plate 2, described inner plate 1 or outer plate 2 are arranged in the both sides of roller 3 in pairs, described inner plate 1, outer plate 2, roller 3 leave pin-and-hole, be assembled together by bearing pin 5, it is characterized in that: described inner plate 1 or outer plate 2 are extended with extending part 6, described extending part 6 is positioned at top and the bottom of inner plate 1 or outer plate 2.
In solution technique, be provided with fillet 7 bottom described extending part 6, when preventing chain-loose, extending part 6 is sagging pulls body.
The chain of this spline structure can stop that foreign matter drops the engagement position of chain, has the advantage operated steadily.
