Abstract

The utility model is related to sports equipment more particularly to a kind of body-building barbells having quick-disassembly structure, to be needed by tool, time-consuming and cumbersome technical problem when solving traditional barbell dismounting, including：Disc and cross bar, cross bar is hollow tubular, and cross bar both ends are equipped with overhanging fixture block, and disc is equipped with the bar shaped limit hole that cooperation fixture block passes through, the longer both ends medial surface of the bar shaped limit hole is equipped with catch, on fixture block there are allow catch along cross bar axially across first through hole；The utility model is relative to traditional locking type barbell, the effect realized limit using the relative rotation of bar shaped limit hole and fixture block and be detached from, it can be realized without using tool in installation and removal, use that more convenient and stability is stronger, and practicability is stronger relative to traditional barbell.

Description

A kind of body-building barbell having quick-disassembly structure

Technical field

The utility model is related to sports equipment more particularly to a kind of body-building barbells having quick-disassembly structure.

Background technology

Barbell is equipment used in a kind of core training Excercise training apparatus and weight lifting.Barbell exercise belongs to weight training One kind, just with barbell exercising equipment, to promote the training of muscle strength, can also using barbell carry out core training, Promote whole harmony, widely used, either shoulder, back, arm, chest etc. the muscle of barbell, by barbell and The iron plate of different weight is cooked muscular endurance training for whole body muscle group, makes fatty combustion with repeatedly several muscular strength special training skills Burning is converted into strong the line of beauty, and reinforcement muscle strength enhances body core ability, improves and moves what part for a long time but still relaxed Muscle；In addition, can more delay muscle aging, increase that sclerotin is close, prevents osteoporosis and other effects, improves endocrine, improve body Harmony is intended to men and women's property of body-building, can be engaged in one of movement of exercise.

Barbell in the prior art is mostly by barbell bar（Whippletree）, disc and clip three parts composition, therefore dismounting When need by tool, it is time-consuming and cumbersome.

Invention content

The purpose of the utility model is to overcome the deficiencies in the prior art, adapt to reality and need, provide one kind and having Quick Release The body-building barbell of structure, to be needed by tool, time-consuming and cumbersome technical problem when solving traditional barbell dismounting.

In order to realize the purpose of this utility model, technical solution is used by the utility model：

A kind of body-building barbell having quick-disassembly structure, including：Disc and cross bar, the cross bar is hollow tubular, described Cross bar both ends are equipped with overhanging fixture block, and the disc is equipped with the bar shaped limit hole that cooperation fixture block passes through, bar shaped limit The longer both ends medial surface in hole is equipped with catch, on the fixture block there are allow catch along cross bar axially across first through hole.

More preferred, the first through hole quantity is 2 and is symmetricly set on cross bar both sides.

More preferred, the bar shaped limit hole is ellipse or rectangle.

It is more preferred, the shape and size all same of the fixture block and bar shaped limit hole.

It is more preferred, be additionally provided on the cross bar allow catch along cross bar radially across the second through-hole.

Operation principle：When needing to install disc, disc is placed vertically, rotary bar makes fixture block be limited with bar shaped The alignment of position hole, rotary bar makes first through hole be aligned with catch after insertion, and the disc after installing at this time will not fall off；When making When user lifts or places down the weight, on the upside of bar shaped limit hole or the catch of downside the second through-hole of insertion prevents disc in cross bar Upper sliding.

The beneficial effects of the utility model are：

Relative to traditional locking type barbell, limits and be detached from using the realization of the relative rotation of bar shaped limit hole and fixture block Effect can be realized in installation and removal without using tool, relative to traditional barbell use it is more convenient and Stability is stronger, and practicability is stronger.

Specific implementation mode

The utility model is further illustrated with reference to the accompanying drawings and examples：

Embodiment 1：

It is a kind of body-building barbell having quick-disassembly structure as shown in Figs. 1-2, including：Disc 1 and cross bar 2, the cross bar 2 For hollow tubular, 2 both ends of the cross bar are equipped with overhanging fixture block 3, and the disc 1 is equipped with the item that cooperation fixture block 3 passes through Shape limit hole 4, the 4 longer both ends medial surface of bar shaped limit hole are equipped with catch 5, on the fixture block 3 there are allow catch 5 along cross Bar axially across first through hole 6.

6 quantity of the first through hole is 2 and is symmetricly set on fixture block both ends, the bar shaped limit hole 4 be ellipse or Rectangle, shape and the size all same of the fixture block 3 and bar shaped limit hole 4 are additionally provided on the cross bar 2 and allow catch 5 along cross Bar radially across the second through-hole 7.

What the embodiments of the present invention were announced is preferred embodiment, and however, it is not limited to this, the common skill of this field Art personnel understand the spirit of the utility model easily according to above-described embodiment, and make different amplification and variation, but as long as The spirit of the utility model is not departed from, it is all within the protection scope of the present utility model.
