Problems solved by technology

When the existing sitting body forward bending test device is in use, after the push plate on the vernier is pushed out, it needs to be returned to the original point when it is used again. When pushing the push plate, it is inconvenient for the tester to control the push plate The speed of the push plate often has a large inertial force, which makes the measurement data inaccurate and cannot truly reflect the physical fitness of the students, and manual control makes it inconvenient to reset the push plate, and the test efficiency is low. It is inconvenient to adjust the height of the vernier for the students. In view of this, we propose a sitting and forward bending exercise device for physical fitness testing.

Abstract

The present invention relates to the field of physical fitness test equipment, and particularly relates to a sit-and-reach motion device convenient for physical body testing. The sit-and-reach motiondevice comprises a bottom plate, wherein a reference plate is fixed on the bottom plate; the reference plate is perpendicularly fixed on the left side edge of the bottom plate; a vernier scale is arranged on the reference plate; the vernier scale is glidingly connected with a push plate; the vernier scale is connected with the bottom plate and the reference plate through a height adjustment mechanism; a convex rod is fixed at the right end of the vernier scale; the push plate and the convex rod are connected through a spring I; a sliding groove is formed in the upper side face of the vernier ruler; the push plate is slidably connected in the sliding groove; a speed limiting mechanism is arranged in the vernier scale; and the push plate is connected with the speed limiting mechanism. According to the sit-and-reach motion device convenient for physical body testing, through the height adjusting mechanism, the height of the vernier scale is adjusted; the moving speed of the push plate isautomatically limited through the speed limiting mechanism, and the structure is simple; and the push plate is kept motionless in the stop position by using an anti-backup mechanism, so that the testdata is conveniently read, and the push plate can be quickly reset.

Description

technical field [0001] The invention relates to the field of physical fitness testing equipment, in particular to a sitting body forward bending exercise device for physical fitness testing. Background technique [0002] Sitting and forward bending is a physical fitness test item for primary and secondary schools. Its purpose is to measure the possible range of motion of the trunk, waist, hip and other joints in a static state, mainly reflecting the extensibility of the joints, ligaments and muscles in these parts. and the level of development of elasticity and body flexibility. When the existing sitting body forward bending test device is in use, after the push plate on the vernier is pushed out, it needs to be returned to the original point when it is used again. When pushing the push plate, it is inconvenient for the tester to control the push plate The speed of the push plate often has a large inertial force, which makes the measurement data inaccurate and cannot truly ...
