Abstract
The utility model belongs to the physical exercise equipment field relates to a seat trunk bending forwards prevents device that knee joint flexion used, its characterized in that: ground is placed in to the base, and square sliding sleeve overlaps in square litter, two lower extremes of square litter and base welded joint, and above the 6 lower extreme welded joint side sliding sleeves on the cylinder, spring, slick and sly cover borehole jack are outside the cylinder, and slick and sly cover side sets up fastening screw, welded joint clamp plate, links firmly the rubber slab below the clamp plate. Use the device and both hands to press the beneficial effect that the knee joint compared to be: the rubber plate voltage has been avoided leading to the fact the drawback that the knee joint is painful, knee joint flexion is cannot kept under control for a short time to the pressing force with both hands pressing force da yi on the knee joint under the clamp plate.
Description
Technical field
The utility model belongs to field of sports equipment, relates to the device that a kind of sitting body anteflexion prevents knee joint bending.
Background technology
Sitting body anteflexion is one of National Standard for Sports Training content, requires that sole touches 0 datum plate both legs knee joint and stretches, in both hands finger tip push away vernier carry out exercise test.Bending easily appears in above-mentioned test a few peoples knee joint, trace it to its cause with pliability inaccurate coordination, can not action anxiety up to standard relevant.Occur that for preventing knee joint crooked test achievement is inaccurate, pressing knee joint energetically by companion's both hands at present can feel pain, and pressing force is little, can not control knee joint bending.Now lack the device that a kind of sitting body anteflexion prevents knee joint bending.
Summary of the invention
For solving above-mentioned background technology Problems existing preferably, the purpose of this utility model is to provide the device that a kind of sitting body anteflexion prevents knee joint bending, the technical scheme taked is formed by with lower component: base is placed in ground, the side's sliding sleeve side of being placed on litter, litter two lower end, side and base weld connection, above cylinder lower end weld connection side sliding sleeve, spring, round slide-sleeve borehole jack are outside cylinder, round slide-sleeve side arranges trip bolt, weld connection pressing plate, and be connected rubber slab below pressing plate.
The side's of moving left and right sliding sleeve can be with dynamic pressure plate to move forward and backward.
Pressing plate rubber slab presses to above knee joint, is fixed by trip bolt.
Use this device press knee joint with both hands compared with beneficial effect be: under pressing plate, rubber slab is pressed in above knee joint, avoids with the hands pressing force great Yi and causes that gonalgia, pressing force are little cannot keeps under control knee-sprung drawback.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The sitting body anteflexion that Fig. 1 is prevents the device master of knee joint bending from looking sketch;
Fig. 2 is that sketch is looked on a left side of Fig. 1;
Fig. 3 is the diagrammatic top view of Fig. 1;
Fig. 4 is that Fig. 3 pressing plate is turned right 90 ° the simplified schematic diagram of not pressing knee joint to facilitate tester to sit down to stand.
Detailed description of the invention
With reference to accompanying drawing: base 2 is placed in ground 1, side's sliding sleeve 9 side of being placed on litter 10, litter 10 liang of lower ends, side and base 2 weld connection, above cylinder 6 lower end weld connection side sliding sleeve 9, spring 8, round slide-sleeve 5 borehole jack are outside cylinder 6, round slide-sleeve 5 side arranges trip bolt 7, weld connection pressing plate 4, and be connected rubber slab 3 below pressing plate 4.When using this device, testee's both feet palm leans against sitting body anteflexion detector datum plate 11, and the side's of moving left and right sliding sleeve band dynamic pressure plate moves and is pressed in above knee joint, is fixed by pressing plate by trip bolt, preventing under knee joint bending prerequisite, hand push vernier can complete test.
