Abstract

A torsion spring for a foot-operated tank pressing device is provided with a cylindrical spring body, wherein the two ends of the spring body extend oppositely to form a long spring arm and a short spring arm both tangent to the spring body; the tail ends of the long spring arm and the short spring arm are outward bent to form right angles, and are on the same side; the included angle of the extending lines of the long spring arm and the short spring arm is 50 DEG; the right-angled tail end of the long spring arm is 44mm; and the right-angled tail end of the short spring arm is 39mm. The torsion spring provided by the utility model is made through winding a spring steel wire with the diameter of 4.4mm, can be sleeved on a shaft of the foot-operated tank pressing device when being used, the tail end of the long spring arm is propped against the bottom of a pressure plate, the tail end of the short spring arm is propped against the upper part of a base plate, so that under the action of the external force, the long spring arm can move around the shaft of the foot-operated tank pressing device, the kinetic energy is converted to the static energy, the static energy can be converted to the kinetic energy for elastic recovery so as to drive the pressure plate to reposition after the external force is removed.

Description

A kind of foot-operated pressing can device is used torsion spring

Affiliated technical field

The utility model relates to a kind of torsion spring, be specifically related to a kind of can with the matching used torsion spring of foot-operated pressing can device.

Background technique

The torsion spring of in people's daily life, using is made up of cylindrical spring body and two spring arms, and two spring arms extend from the two ends of spring body relatively, and tangent with the spring body, in practical application, in order to satisfy the demand of different product, also needs the spring arm is made certain improvements.

Summary of the invention

The purpose of the utility model is that a kind of foot-operated pressing can device that designs to above-mentioned situation is used torsion spring, and the spring arm adopts special construction, can satisfy and the matching used requirement of foot-operated pressing can device.

The purpose of the utility model is achieved in that a kind of foot-operated pressing can device uses torsion spring, is provided with cylindrical spring body, and spring body two ends are extended the long spring arm and short spring arm tangent with the spring body relatively; Long spring arm outwards is bent into the right angle with short spring arm end and at homonymy, long spring arm is 50 ° with the angle of short spring arm line stretcher, and long spring arm right angle end is 44mm; Short spring arm right angle end is 39mm, and the utility model employing diameter is that the Spring Steel Wire coiling of 4.4mm forms, and during use the spring body is enclosed within on the axle of foot-operated pressing can device; Long spring arm end withstands on the pressing plate bottom, and short spring arm end is against base plate top, under external force; Long spring arm can be around the axle motion of foot-operated pressing can device; Kinetic energy is converted into potential energy, removes the kinetic energy that potential energy after the external force is converted into resilience, drives pressing plate and resets.

The beneficial effect of the utility model is, the spring arm is terminal vertical with the spring arm and link up with at the right angle of homonymy, and the pressing plate of foot-operated pressing can device and base plate are separated, and is simple in structure, convenient and practical.

Description of drawings

Fig. 1 is the plan view of the utility model;

Fig. 2 is the plan view of the utility model.

Among the figure: 1, spring body; 2, long spring arm right angle is terminal; 3, lack spring arm right angle end; 4, long spring arm; 5, lack the spring arm.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

A kind of foot-operated pressing can device is used torsion spring, as shown in Figure 1ly is provided with cylindrical spring body 1, and spring body 1 two ends are extended the long spring arm 4 and short spring arm 5 tangent with the spring body relatively; Long spring arm 4 outwards is bent into right angle and as shown in Figure 2 easily at homonymy with short spring arm 5 ends, and long spring arm is 50 ° with the angle of short spring arm line stretcher, and long spring arm right angle terminal 2 is 44mm; Short spring arm right angle terminal 3 is 39mm, and the utility model employing diameter is that the Spring Steel Wire coiling of 4.4mm forms, and during use spring body 1 is enclosed within on the axle of foot-operated pressing can device; Long spring arm right angle terminal 2 withstands on the pressing plate bottom, and short spring arm right angle terminal 3 is against base plate top, under external force; Long spring arm 4 can be around the axle motion of foot-operated pressing can device; Kinetic energy is converted into potential energy, removes the kinetic energy that potential energy after the external force is converted into resilience, drives pressing plate and resets.
