Outdoor power assisting device with two-way spring

Abstract

The invention discloses an outdoor power assisting device with a two-way spring. The outdoor power assisting device structurally comprises a supporting plate mechanism, a fixing frame and an elastic mechanism, the right end of the supporting plate mechanism is connected with the right end of the fixing frame, the lower end of the elastic mechanism is installed in the fixing frame, a spring rod is bidirectionally stretched in a welding plate and a fixing pipe sleeve, and the limiting effect is achieved; an excessive rotation range amplitude of an extrusion mechanism is avoided, the top of an elastic mechanism and the bottom of an anti-skid supporting plate are movably supported, the anti-skid supporting plate is prevented from applying an excessive extrusion force to the elastic mechanism, the upper end of a two-way spring slides within a certain range at the bottom of the extrusion mechanism, and the extrusion mechanism is prevented from excessively pressurizing the two-way spring; and during extrusion, the lower end of the two-way spring transversely moves on the guide sliding rod through the sliding block, the situation that the two-way spring is excessively extruded so that the elastic deformation of the two-way spring is excessive is avoided, the two-way spring is prevented from falling off, and the two-way spring keeps the good elastic effect in the long-time power assisting process.

Description

technical field [0001] The invention relates to the field of elastic boosting, and more specifically, relates to an outdoor boosting device with two-way springs. Background technique [0002] In the process of practicing long jump outdoors, athletes need to use a two-way spring outdoor booster device. The spring is squeezed by the athlete's foot, and the elastic force generated by the spring drives the support plate to bounce, thus providing the athlete's foot with a bouncing force. Power to improve the training effect of athletes, but due to the long-term extrusion of the spring, the spring has a certain elastic coefficient, and the spring is directly fixed at the lower end of the support plate, and excessive extrusion rebound is prone to occur when the spring remains stationary , so that the spring itself loses its elastic force, which leads to a gradual decrease in the elastic force provided for the support plate, thereby reducing the performance of the booster device.

Power to improve the training effect of athletes, but due to the long-term extrusion of the spring, the spring has a certain elastic coefficient, and the spring is directly fixed at the lower end of the support plate, and excessive extrusion rebound is prone to occur when the spring remains stationary , so that the spring itself loses its elastic force, which leads to a gradual decrease in the elastic force provided for the support plate, thereby reducing the performance of the booster device. At the same time, the spring is easy to fall off from the lower end of the support plate during excessive extrusion, resulting in In the process of assisting athletes, athletes tend to lose gravity from the support plate and fall down
