Description

Safe barbell

Technical field

A kind of sports apparatus is the utility model is related to, more particularly to a kind of safe barbell.

Background technology

At present, barbell exercising has two ways, and one kind is counter balanced Smith machine training, and another kind is free barbell exercising.Shi Mi The characteristics of this machine maximum is exactly the moving direction that the right and left has fixed track limitation barbell, first, so that training appearance It will definitely be dominated by machine, it is impossible to correctly have an effect, muscle cannot take exercise well, and the time, which has been grown, makes many wrong actions will Form a habit, while malfunction can also apply pressure to joint；Secondly, will have 1/3 weight during training is to rely on machine Undertake, reduce training strength；Also, counter balanced Smith machine trains the balance that can reduce body, reduces itself to free weight Control ability；And when people is exhausted, it is necessary to which user is put into barbell on hook, trouble is laborious also dangerous.Freely For barbell when carrying out heavy weight training, if do not protected, user is easy to injury.Both training methods are unsuitable for Deep-knee-bend is trained, and the former is due to that track is fixed, and does not meet the mode of having an effect of people, and the latter is in order at secure context consideration.

The content of the invention

The utility model aims to overcome that above-mentioned deficiency, there is provided a kind of science is taken exercise, safe and reliable safe barbell.

Technical scheme is used by the utility model solves its technical problem：Theory of mechanics：Safe barbell by barbell stand, Roller, wrap up in rubber wire rope, barbell, spring vibration damper, guide wheel group into.Wherein there are roller bearings, nest coil spring, chaste tree in roller Take turns, wrap up in rubber wire rope, electric wire, chaste tree tooth, magnetic valve, battery.There are petcock plate, lever, connecting rod, switch sheet reset bullet on barbell Spring, contact, electric wire.Circuit theory：Electric current out enters cylinder axis by electric wire from anode, then wraps up in glue steel by one Cord reach roller outside, wrapping up in rubber wire rope has steel wire rope metal-cored, wrap up in rubber wire rope by directive wheel enter barbell after, by electricity Line is connected with contact, and by pressing petcock plate, drivening rod makes contact be contacted with barbell, and electric current is reached another by barbell The contact of head, enter via electric wire and wrap up in rubber wire rope, then roller is reached by wrapping up in rubber wire rope, into cylinder axis afterwards by electric wire Into magnetic valve, GND is arrived by magnetic valve again.When not in use or unclamping petcock plate, chaste tree wheel in roller and Chaste tree tooth is constantly in button death situation state in the presence of roller nest coil spring, and barbell may only rise, it is not possible to decline；In use, Need to press petcock plate, now barbell is powered, and when barbell is in propradation, magnetic valve could be by chaste tree tooth and chaste tree wheel point From only at this moment barbell can be just freely lifted.

The beneficial effects of the utility model are that user can safely carry out alone barbell exercising；Rail-free designs, thick stick Fluid motion direction is free, and such user can use correct action training, and the training to muscle also complies with the normal of people and had an effect Mode, extra pressure will not be caused to joint；Barbell weight is attached on the person completely, reaches more preferable training effect；Enhancing The balance of user's body, improve the control ability to free weight；Barbell falling stop can be achieved in trip switch, convenient to save Power；It can with safe and scientific carry out deep-knee-bend training.

Embodiment

In figure, safe barbell by barbell stand 2, roller 1, wrap up in rubber wire rope 3, barbell 4, spring vibration damper 5, directive wheel 6 compositions.Wherein there are roller bearings 14, nest coil spring 15, chaste tree to take turns 16, wrap up in rubber wire rope 3, electric wire 8, chaste tree tooth 17, electromagnetism in roller 1 Valve 18, battery 19.There are petcock plate 12, lever 11, connecting rod 13, switchboard back-moving spring 10, contact 9, electric wire 8 on barbell 4. Cylinder axis 20 wrap up in rubber wire rope 3 to connection one outside roller 1, and wrapping up in has steel wire rope metal-cored 7 in rubber wire rope 3.

After players stress on both hands barbell 4, petcock plate 12 is depressed, two on two petcock plates 12 Contact 9 contacts barbell 4, and electric current out enters cylinder axis 20 from the positive pole of battery 19 by electric wire 8, arrived by wrapping up in rubber wire rope 3 Enter barbell 4 up to outside roller 1 around roller 1 and directive wheel 6, after connected with contact 9 by electric wire 8 and contacted again with barbell 4, electric current leads to The contact 9 that barbell 4 reaches other end is crossed, enters via electric wire and wraps up in rubber wire rope 3, then roller 1 is reached by wrapping up in rubber wire rope 3, is entered Enter cylinder axis 20 and magnetic valve 18 is entered by electric wire afterwards, the negative pole of battery 19 is arrived by magnetic valve 18 again, now circuit turn-on, electricity Magnet valve 18 is in attracting state, but due to wrapping up in the stress of rubber wire rope 3 on roller 1, chaste tree tooth 17 can not depart from chaste tree wheel 16, and barbell 4 is not It can decline so magnetic valve 18 can't adhesive.Now players slightly upper must lift barbell 4, wrap up in the releasing of the stress of rubber wire rope 3, The adhesive chaste tree tooth 17 of magnetic valve 18 depart from chaste tree wheel 16, now barbell 4 can any rise and fall, barbell 4 decline when wrap up in rubber wire rope 3 Dragging roller 1 rotates, and compresses the internal socket coil spring 15 of roller 1, roller 1 is in the presence of nest coil spring 15 when barbell 4 rises Reversing makes to wrap up in outside the winding roller 1 of rubber wire rope 3.

When not in use or unclamping petcock plate 12, the chaste tree wheel 16 and chaste tree tooth 17 in roller 1 are in nest coil spring 15 Under effect, button death situation state is constantly in, barbell 4 may only rise, it is not possible to decline.

Safety analysis：1st, when players hand grabs bar, barbell will not decline, it is necessary to after slightly rising, ability Free rise and fall.Ensure that hand one will not run into the danger that barbell declines immediately when grabbing barbell.

2nd, when carrying out barbell exercise, any situation no matter occurs, as long as user's hand unclamps petcock plate, barbell is stood Carve and stop declining, it is ensured that personal security.
