It connects, the other end of driving hydraulic cylinder and the left part of bottom plate are hinged.During experiment, by the following fixation for being fixed on bar shaped of fabric to be measured
It presss from both sides on a, the top of fabric to be measured is fixed on the geometrical clamp b of bar shaped, the section of fabric, bottom plate and flap forms triangle；
Control driving hydraulic cylinder elongation so that flap rotates, and then stretches fabric；Due to driving hydraulic cylinder relative to fabric farther away from
The hinge joint of bottom plate and flap, therefore, according to lever principle, the stroke of the stroke ratio fabric of driving hydraulic cylinder is longer, is applied to
Power increase on fabric, can allow the smaller driving hydraulic cylinder of power meet needed for drawing force.Due to bottom plate right side edge with
The right side edge of flap is hinged using line, and it is parallel can to ensure that geometrical clamp a is always maintained at geometrical clamp b, and then ensures to apply
It is added in the uniform of drawing force on fabric.
Further, the plate upper surface left end is fixedly connected with bottom plate hinge base, the lower surface of the extension rod
Left end is fixedly connected with extension rod hinge base, and one end of the bottom plate hinge base and driving hydraulic cylinder is hinged, the extension
The other end of bar hinge base and driving hydraulic cylinder is hinged.The setting of bottom plate hinge base and extension rod hinge base causes this reality
More stablized with novel operation.
Further, the flap surface offers flap hole, can mitigate the weight of flap, flap is facilitated to rotate.
Preferably, the extension rod is connect with flap left side central portion, the both ends difference on the left of the left end and flap of extension rod
It is connected by a bracing piece, can ensure the stability that power is transmitted, increase fastness.
Preferably, the geometrical clamp a is hinged with bottom plate, and the geometrical clamp b is hinged with flap.It can ensure entirely to stretch examination
Process is tested, plane where fabric is along to the drawing force of fabric is avoided because the angle of bottom plate and flap changes and leads
The stretching to fabric is caused to change angle.
The utility model has the advantages that：
The utility model utilizes lever principle, and the deformation of the stroke ratio fabric of driving hydraulic cylinder is longer, is applied on fabric
Power increase, can allow the smaller driving hydraulic cylinder of power meet needed for driving force；
Bottom plate is hinged with flap using line, can ensure that geometrical clamp a is always maintained at parallel, Jin Erbao with geometrical clamp b
Card is applied to the uniform of drawing force on fabric.
