Description
Technical field
The present invention relates to chain technical field more particularly to a kind of chains for preventing link plate from deforming.
Background technique
Chain is constituted and multiple chain links formed by a pair of of link plate are connected in series.One in adjacent chain link
The front end of a chain link is connected in a manner of being able to rotate relative to the rear end of another chain link.Chain passes through the length direction in chain
It is stretched and advances to a direction.
For example, can enumerate the front-end and back-end for being spaced in chain link between link plate is constant plate chain.?
In plate chain, need to prepare between the relatively narrow inner link in interval and link plate between 2 kinds of chain links, i.e. link plate
The relatively wide outer link in interval.
A kind of existing eccentric chain, is made of a kind of different chain link of the front-end and back-end for being spaced in chain link between link plate.
According to this chain, a chain link in adjacent chain link is the end of the relatively narrow side in the interval between link plate to be inserted into
State in the end of the wider side in interval between the link plate of another chain link is connect with another chain link.
But in eccentric chain, need to keep the interval between link plate different in the front-end and back-end of chain link.Therefore,
The middle part that there is each link plate the length direction relative to chain obliquely to extend between the front-end and back-end of link plate.By
In such structure, when chain is when its length direction stretches, stress concentrates on the middle part of each link plate, may make centre
Portion is deformed.

The present invention as shown in Figs 1-4 provides a kind of chain for preventing link plate from deforming, by multiple by a pair of of link plate 01
The chain link of formation is constituted and the bayonet lock 02 for being inserted into bushing 03 is connected in series, the front end of in adjacent chain link a chain link
Rear end relative to another chain link is connected in a manner of it can be freely rotated, and the chain passes through the length direction in the chain
It is stretched and advances to a direction, the link plate of the chain includes the 1st end 011；2nd end 013, be located at it is described
The opposite side in 1st end；And middle part 012, it is arranged between the 1st end 011 and the 2nd end 013, it is described
1st end 011 and the 2nd end 013 extend to the length direction of the chain respectively；The length of the middle part and the chain
Direction intersects, and the middle part 012 has the 1st cross part 0121 and the 2nd cross part 0122, the 1st cross part 0121 and institute
It states the length direction of chain to intersect with the 1st angle, the length direction of the 2nd cross part 0122 and the chain is with the 2nd angle
Intersect, the 2nd angle the 1st end 011 opposite with the 1st angle is symmetric, the absolute value of the 2nd angle and
The absolute value of 1st angle is equal；The middle part 012 relative to the 1st end 011 intersecting angle and it is described in
Between portion 012 relative to the intersecting angle of the 2nd end 013 be obtuse angle；2nd end 013 includes 0131 He of a link plate
B link plate 0132, a link plate 0131 are connect with the 1st cross part 0121, are parallel to the 1st end 011, the b link plate

0131, setting in this way, the cooperation that the b link plate and the bayonet lock 03 can be more stable.
Further, the shape of the bushing 02 is tubular, and inner wall is equipped with groove 021, uses solid in the groove 021
The greasy property of chain can be enhanced in oil refill, setting in this way, chain can be allowed to realize non-maintaining.
Further, the thickness of the middle part 012 is greater than the thickness of the 1st end 011, the centre in existing chain
Portion is easiest to deformation, thickeies middle part to resist stronger stress for this technical problem in the present invention.
Further, the thickness of the thickness and a link plate 0131 and the b link plate 0132 of the 1st end 011
Degree is the same.
Further, two walls of the 1st end 011 respectively with a link plate 0131 and the b link plate 0132
Inner wall abuts against.
Further, the through hole Yu the bayonet lock 03 of the 1st end 011 are clearance fit, the 1st end 011
Through hole aperture be greater than the bayonet lock 03 diameter, the 1st end described in this way can more freely be rotated around the bayonet lock 03.
Further, the through hole of a link plate 0131 and the bayonet lock 03 are clearance fit, a link plate
0131 through hole aperture is greater than the diameter of the bayonet lock 03；The through hole of the b link plate 0132 and the bayonet lock 03 were
It is full of cooperation, the through hole aperture of the b link plate 0132 is less than in the diameter of the bayonet lock 03.
Further, chamfered has all been done at the both ends of the bayonet lock 03, convenient for the assembling of chain.
The above is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is included within the scope of the present invention.
