Abstract
The utility model relates to a machinery dismounting device technical field, especially a laborsaving type draws horse. It includes the lead screw, draw the seat, transport persons or goods by cart and draw the claw, and the lead screw is inserted in the central authorities of drawing the seat, transports persons or goods by cart and connects the edge drawing the seat, draws the claw to connect at the end of transporting persons or goods by cart, is equipped with the single arm -drag on drawing the claw, is equipped with spring and filler ring in the single arm -drag. The single arm -drag of flexible loop bar structure is set up at the top tilt up who draws the claw to set up spring and convex filler ring in the single arm -drag, form centre of a circle supporting mechanism. During the use, the filler ring extends to the central authorities of wheel body bottom through the single arm -drag to hug closely the axis body under the effect of spring, with the hole edge overlapping of wheel body, messenger's die pull direct action in centre of a circle position, effectively avoid wheel body distortion extrusion axis body, reduced and drawn the degree of difficulty, labour saving and time saving.
Description
Technical field
The utility model relates to mechanical provision for disengagement technical field, and especially a kind of effort-saving draws horse.
Background technology
In machinery industry, often relate to motor pulley, stator, rotor and the field-strip between various gear and axle in motor, need to use a kind of instrument being referred to as to draw horse.Form screw mechanism between its nut and screw mandrel, nut is fixed in main body, and after the front end of pulling claw is linked up with gear hook jail, turn screw mandrel makes its front end and is coupling tactile and continues forward to withstand axle, and wheel shaft can be made to be separated.The existing edge that pulling claw is buckled in wheel body when drawing horse to work applies pulling force, and the force localization of wheel body and axis body is in the center of circle of wheel body, causes force target to depart from, and easily makes wheel body distortion extruding axis body and is difficult to extract, and wastes time and energy.
Utility model content
Depart to overcome the existing horse point of application that draws, the deficiency wasted time and energy, the utility model provides a kind of effort-saving and draws horse.
The utility model solves the technical scheme that its technical problem adopts: a kind of effort-saving draws horse, comprise screw mandrel, pulling seat, transport persons or goods by cart and pulling claw, screw mandrel is inserted in the central authorities of pulling seat, transport persons or goods by cart and be connected to the edge of pulling seat, pulling claw is connected to the end of transporting persons or goods by cart, pulling claw is provided with torque arm, and torque arm is provided with spring and filler ring.
According to another embodiment of the present utility model, comprising torque arm is further telescopic sleeving rod, is inclined upwardly and is connected to the top of pulling claw.
According to another embodiment of the present utility model, comprising filler ring is further circular arc, is connected to the front end of torque arm.
According to another embodiment of the present utility model, comprise spring housing further in torque arm, be stuck between torque arm and filler ring.
The beneficial effects of the utility model are, being inclined upwardly at the top of pulling claw arranges the torque arm of telescopic sleeving rod structure, and in torque arm, arrange the filler ring of spring and circular arc, form center of circle supporting mechanism.During use, filler ring extends to the central authorities bottom wheel body by torque arm, and is close to axis body under the action of the spring, overlapping with the inner port edge of wheel body, make pulling capacity directly act on position, the center of circle, effectively avoid wheel body distortion to extrude axis body, reduce drawing difficulty, time saving and energy saving.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure, 1. screw mandrels, 2. pulling seat, 3. transport persons or goods by cart, 4. pulling claw, 5. torque arm, 6. spring, 7. filler ring.
Detailed description of the invention
If Fig. 1 is structural representation of the present utility model, a kind of effort-saving draws horse, comprise screw mandrel 1, pulling seat 2, transport persons or goods by cart 3 and pulling claw 4, screw mandrel 1 is inserted in the central authorities of pulling seat 2, to transport persons or goods by cart 3 edges being connected to pulling seat 2, pulling claw 4 be connected to transport persons or goods by cart 3 end, pulling claw 4 is provided with torque arm 5, and torque arm 5 is provided with spring 6 and filler ring 7.Torque arm 5 is telescopic sleeving rod, is inclined upwardly and is connected to the top of pulling claw 4.Filler ring 7, in circular arc, is connected to the front end of torque arm 5.Spring 6 is enclosed within torque arm 5, is stuck between torque arm 5 and filler ring 7.
Be inclined upwardly at the top of pulling claw 4 and the torque arm 5 of telescopic sleeving rod structure is set, and the filler ring 7 of spring 6 and circular arc is set in torque arm 5, form center of circle supporting mechanism.During use, filler ring 7 extends to the central authorities bottom wheel body by torque arm 5, and is close to axis body under the effect of spring 6, overlapping with the inner port edge of wheel body, make pulling capacity directly act on position, the center of circle, effectively avoid wheel body distortion to extrude axis body, reduce drawing difficulty, time saving and energy saving.
