Between allow repair and maintenance personnel to adjust, increase cost of labor, result in unnecessary waste.
The content of the invention
To solve the above problems, the purpose of this utility model is to provide a kind of swelling device of drive chain, by butt-joint
The coincidence displacement of Sliding Control two linking arm of the screw in chute, and then adjust the angle of two connecting rods and exist ensureing roller group
Rolling in drive chain, so as to the slack for adjusting drive chain makes chain keep tensioner, increased the safety of system.
To realize above-mentioned technical purpose, above-mentioned technique effect is reached, this utility model is achieved through the following technical solutions：
A kind of swelling device of drive chain, including the first roller group, the second roller group, bottom is welded on first rolling
Head rod in wheel group, bottom is welded on the second connecting rod in second roller group, the first linking arm, the second connection
Arm；The head rod is flexibly connected with the top of second connecting rod by bearing pin；One end of first linking arm
Connect the head rod, the other end is provided with butt-joint screw；It is provided with second linking arm and is available for the butt-joint spiral shell
The chute that nail slides, described second linking arm one end connects second connecting rod, and the other end is fixed by the butt-joint screw
It is connected with first linking arm in the chute.
Further, that one end for being provided with first linking arm of the butt-joint screw is provided with waist-shaped hole, described to touch
Weldering screw is arranged in the waist-shaped hole slidably.
Further, the first sprocket wheel is connected with the second sprocket wheel by drive chain, and first roller group is in the driving
The lower section of chain is rolled, and second roller group is rolled in the upper section of the drive chain.
The beneficial effects of the utility model are：
This utility model is placed on host driven chain inner side, by the butt-joint screw on the first linking arm in the second connection
The coincidence displacement of the linking arm of Sliding Control two in the chute of arm, so adjust two connecting rods angle come ensure roller group drive
Rolling on dynamic chain, so as to the slack for adjusting drive chain makes chain keep tensioner, reduces the cost of manual adjustment, increases
The safety of system is added.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
