Sack is collected, and the outstanding Beam arms of weigh assembly are generally fixed, two kinds of Leftward/rightward rotating, fixed outstanding Beam arms space-consuming
Greatly, and easily there is damage caused by human factor, Leftward/rightward rotating hangs Beam arms and the problem of weighting error is big easily occurs, comprehensive
More than, problems be present in used weigh assembly：Function is few, weighing sensor is fragile, weighting error is big, space-consuming is big
The shortcomings of.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of small folding formula weighing structure, existing to solve
Caused above-mentioned multinomial defect in technology.
To achieve the above object, the utility model provides following technical scheme：A kind of small folding formula weighing structure,
Including sensor fixture, sensor connecting piece, weighing sensor, scale support, scale hinge, hinge axle, shouldered shaft set, scale pawl,
Scale is linked up with, and the end of the sensor fixture and weighing sensor is detachably connected, sensor connecting plate end and biography of weighing
The front end of sensor is detachably connected, and scale support is connected front edge of board with sensor to be detachably connected, and shouldered shaft set is fixed on scale conjunction
On page, scale hinge on scale support, is equipped with a pair of scale pawls, scale pawl front end is provided with a pair of scales by hinge axis connection on scale hinge
Hook.
Preferably, the scale pawl is connected by scale pawl pivot pin with scale hinge.
Preferably, extension spring is installed, the both ends of the extension spring withstand on two scale pawls respectively inside the scale hinge
End.
Beneficial effect using above technical scheme is：Scale support and scale hinge during the hinge expansion of the utility model structure
Binding face is horizontal by about -15 degree angles, and scale closes when can prevent from installing collection vessel
Page is folded up, and a pair of scale pawls is housed, scale pawl is connected by scale pawl pivot pin with scale hinge, scale pawl front end on scale hinge
A pair of scale hooks are installed, for hanging collection vessel, disconnecting prevention structure is designed with scale hook, prevents collection vessel from coming off.
Meanwhile extension spring is installed inside scale hinge, the both ends of extension spring withstand on the end of two scale pawls respectively, are closed for scale pawl
Reset force is provided.
