Description

The parallel bars of heavy burden can be added

Technical field

The utility model belongs to sports equipment technical field, specifically, more particularly to a kind of parallel bars adding heavy burden.

Background technology

Parallel bars bending and stretching of the arms is a kind of most common parallel bars campaign, it can effectively temper the upper limbs force of human body.Traditional Parallel bars bending and stretching of the arms belongs to from retraining, when the increase of person taking exercise's strength to a certain extent when, the train on that generates is difficult It is promoted to further.For the above situation, occur some weight belts on the market, it can be by this waistband person taking exercise Waist hangs the weights such as dumbbell plate to promote train on.But this waistband when in use can generate the waist of person taking exercise certain Injury, and the carrying back and forth of the weights such as dumbbell also can bring big inconvenience to exercise.

Invention content

The purpose of this utility model is to provide a kind of parallel bars for adding heavy burden simple in structure, which can be bending and stretching of the arms Person taking exercise provides safe and reliable, convenient, flexible heavy burden.

To achieve the above object, the utility model uses following technical scheme：

It is a kind of to add the parallel bars of heavy burden, including it is erected at two cross bars being mutually parallel on ground, the every cross The heavy burden frame slided up and down is equipped on bar, the lower part of the heavy burden frame is equipped with downward heavy burden, and the top of the heavy burden frame is set There is the pressing plate that can be pressed on shoulder.

Further, the heavy burden frame includes two guide posts being mutually parallel, is parallel to the crossbeam of cross bar, the guide post with Cross bar slides up and down connection, and the fixer is located at two guide post upper ends, and the pressing plate is set to crossbeam lower part.

Further, the guide post lower end is equipped with limit, and compressed spring is equipped between the limit and cross bar.

Further, the guide post lower part is machined with external screw thread, and the limit is the wing nut being threadedly coupled with guide post.

Further, the pressing plate can be along crossbeam length direction linear slide.

Further, the pressing plate lower part is equipped with cushion.

Compared with prior art, the utility model has the beneficial effects that：

The utility model integrates load-bearing device in parallel bars can efficiently solve traditional parallel bars bending and stretching of the arms raining load deficiency The problem of, and without carrying heavy goods back and forth when person taking exercise's use, it is convenient, flexible；The utility model will bear a heavy burden load in person taking exercise Shoulder can be effectively prevented from heavy burden its body is damaged；The utility model provides heavy burden using compressed spring, can be significantly Reduce equipment overall weight, structure design is simple, and adjusts and bear a heavy burden conveniently.

Specific implementation mode

The utility model is more fully understood for the ease of those skilled in the art, below by specific embodiment and in conjunction with attached drawing pair The utility model is described further.

As shown in Figure 1 and Figure 2, a kind of parallel bars adding heavy burden, including it is the embedded column 1 on the ground of four fixations, fixed Two horizontal cross bars 8 being erected in four columns 1, two 8 height of cross bar are identical and are mutually parallel.In every cross bar 8 There are two connecting plate 11,11 position of connecting plate on two cross bars 8 corresponds for side weldering.It is provided on connecting plate 11 transparent Pilot hole 12, can be slided up and down along pilot hole 12 equipped with the guide post 2 with its clearance fit, guide post 2 in the pilot hole 12.It is leading The lower part of column 2 is machined with external screw thread and wing nut 10 is housed, and compressed spring 9, the both ends of compressed spring 9 are cased on guide post 2 The lower part on the top and connecting plate 11 of wing nut 10 is withstood on respectively.In the upper end fixed frame of two guide posts 2 of same root cross bar 8 Equipped with the crossbeam 4 for being parallel to cross bar 8, transparent rectangle sliding slot 5, the long side and crossbeam of sliding slot 5 are provided at the middle part of crossbeam 4 4 is parallel, and equipped with the slide bar 6 coordinated with its width gaps in sliding slot 5, fixed limit is respectively arranged in the upper and lower part of slide bar 6, So that slide bar 6 can only be along 5 linear slide of sliding slot.It is fixed with pressing plate 3 in the lower end of slide bar 6,3 lower part of pressing plate is equipped with and may be stuck in shoulder On arcwall face, cushion 7 is fixed in arcwall face.

In view of above-described embodiment, the course of work and operation principle of the utility model are as follows：

When semi-girder rises person taking exercise in parallel bars, shoulder can push up pressing plate 3, and crossbeam 4 can drive guide post 2 upward Sliding, compressed spring 9, which can be pressurized, at this time generates elastic force to hinder 2 upward sliding of guide post, and continues to increase resistance, so as to be forging The arm-stretching exercise offer of refining person continues reliably to bear a heavy burden.It is oriented to using two guide posts 2 and can guarantee that entire load-bearing device moves up and down Stability.It is machined with external screw thread in 2 lower part of guide post and wing nut 10 is housed, it is i.e. adjustable by turning wing nut 10 up and down The first decrement of compressed spring 9 is saved to the changeable size born a heavy burden.The pressing plate 3 can be along 4 length direction linear slide of crossbeam It can make pressing plate 3 that can follow the shoulder swing of person taking exercise without falling off always in the movement of entire bending and stretching of the arms.In pressing plate 3 Lower part is equipped with cushion 7 and comfort that equipment uses can be improved and the shoulder of person taking exercise is protected to preserve from.
