Abstract
The utility model provides a leg pressing device used before sports activities, and the left pressing device is good in effect. The leg pressing device comprises two parallel inverted-L-shaped supports, each inverted-L-shaped support comprises a supporting leg fixed to a foundation and a cantilever at the upper end of the supporting leg, threaded holes which penetrate through the cantilevers are formed in the end portions of the cantilevers respectively, a vertical lead screw is arranged in each threaded hole in a penetrating mode, a hand wheel is arranged at the upper end of each lead screw, the two ends of a beam with a rectangular cross section are connected with the lower ends of the two lead screws respectively in a rotating mode through rolling bearings, and two concave portions for supporting the legs are arranged on the upper surface of the beam with the rectangular cross section in a spaced mode. The height of the beam with the rectangular cross section can be adjusted, the cantilevers can be held by hand, and therefore the activity effect is good.
Description
technical field
The utility model relates to sports apparatus, is specifically related to use pressing-leg device before a kind of sports.
background technology
Before sports, need to do warm-up lacing wire warm-up movable, with the lifter motion ability, avoid athletic injury.Present leg pressing campaign is general by the object with certain altitude, and such as high platform, tables and chairs, parallel bars etc., be placed on it leg to carry out the leg pressing campaign.The problem such as but being not steady on one's legs easily appears in this easy leg pressing auxiliary equipment, even the shank ligament is injured.The leg pressing campaign need to be placed on leg with waist with on high object, could obtain satisfied effect.
summary of the invention
The technical problems to be solved in the utility model is used pressing-leg device before being to provide a kind of effective sports.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
Use pressing-leg device before a kind of sports, comprise two juxtaposed " Г " shape supports, each " Г " shape support includes the supporting leg that is fixed on basis and the cantilever of supporting leg upper end, the cantilever end has the screwed hole run through, wear the leading screw of vertically-arranged in screwed hole, the leading screw upper end arranges handwheel, and the two ends of beam with rectangular section are rotationally connected by rolling bearing and two leading screw lower ends respectively, spaced two depressed parts for the support shank of the upper surface of beam with rectangular section.
Use pressing-leg device before above-mentioned sports, be positioned at the handwheel below and near on the leading screw of handwheel, sprocket wheel be set, two sprocket wheels connect by chain.
Use pressing-leg device before above-mentioned sports, the upper surface of depressed part adheres to one deck rubber blanket.
Using pressing-leg device, the length of cantilever before above-mentioned sports is 1-1.2m.
It is cylindrical using pressing-leg device, the cross section of cantilever before above-mentioned sports.
Beam with rectangular section is suspended on two juxtaposed " Г " shape supports by the leading screw of two vertically-arrangeds, during leg pressing, by rotation hand wheel, make leading screw rotate, and then beam with rectangular section moves up and down, make the height of beam with rectangular section suitable, then leg is positioned on depressed part, carry out the leg pressing campaign and get final product, in the process of leg pressing, hand can be held cantilever to keep one's balance.The height of beam with rectangular section can be regulated, and hand can be held cantilever, therefore movable effective.
the accompanying drawing explanation
Below in conjunction with accompanying drawing to further detailed explanation of the utility model:
Fig. 1 is structural representation of the present utility model.
The side view that Fig. 2 is Fig. 1.
In figure: 1 supporting leg, 2 cantilevers, 3 leading screws, 4 sprocket wheels, 5 chains, 6 handwheels, 7 rubber blankets, 8 beam with rectangular sections.
The specific embodiment
As depicted in figs. 1 and 2, use pressing-leg device before a kind of sports, comprise two juxtaposed " Г " shape supports, each " Г " shape support includes the supporting leg 1 that is fixed on basis and the cantilever 2 of supporting leg upper end, the cantilever end has the screwed hole run through, wear the leading screw 3 of vertically-arranged in screwed hole, the leading screw upper end arranges handwheel 6, the two ends of beam with rectangular section 8 are rotationally connected by rolling bearing and two leading screw lower ends respectively, spaced two depressed parts for the support shank of the upper surface of beam with rectangular section.
Be positioned at the handwheel below and connect by chain 5 near sprocket wheel 4, two sprocket wheels are set on the leading screw of handwheel, in order to make two rhizoid thick sticks synchronously rotate.
The upper surface of depressed part adheres to one deck rubber blanket 7, plays anti-skidding effect, and alleviates the tenderness sense that shank directly contacts with crossbeam.
Particularly, the length of cantilever is 1-1.2m.
For the ease of gripping, the cross section of cantilever is cylindrical.
