Abstract

Nowadays, physical labor of people in work is less and less, and physical fitness gets worse and worse, and people do some physical exercises for body health, such as lifting barbells, pushing and lifting a barbell on a panel, and pressing legs by a barbell, etc. Barbells in gyms or homes are basically made of iron, and disks and barbell rods are in old types, and the disks are very easy to slip. So for people doing physical exercises especially newbies, disk slipping is very dangerous. Through designing barbell disks in a pentagon, rolling of the barbell on a plane is effectively prevented. An inner barbell disk and an outer barbell disk are designed in a bended funnel shape, and friction forces and integrating degree between the barbell disks are increased. A central round structure for stopping the barbell disk extends outwards, being beneficial for preferably stabilizing and increasing the length of internal threads in a screw type, so that the barbell disk can be screwed tightly.

Description

A kind of new-type barbell

Technical field

the present invention relates to sports goods, relate generally to a kind of barbell.

Background technology

the work manual labor of people is fewer and feweri now, fitness also worse and worse, people carry out some sports to improve own health, such as lift barbell, dull and stereotyped election barbell, barbell leg pressing etc., barbell in present gymnasium or family is iron substantially, and disc and bar are old-fashioned that, and disc is very easy to landing, this is for the people tempering physical culture, and especially new hand is breakneck thing; And dumbbell plate is round, place and easily disorderly to roll on the ground and in use procedure between disc and unrestricted or friction, this just causes disc to loosen, often using for a moment will tightening nut again, otherwise easily cause disc to drop, cause unnecessary unexpected injury.

Summary of the invention

for above-mentioned defect, the object of the present invention is to provide a kind of structure simple, can careless regulating weight, meet different people requirement, prevent from disorderly rolling in the plane, while can ensure the new-type barbell of one of tight type between dumbbell plate and compatible degree.

invent the technical scheme adopted is for this reason:

comprise a bar, described bar two ends are provided with bar cover, bar puts and is provided with external screw thread, described bar puts cover some discs, disc surrounding of telling is pentagon, disc of telling is divided into interior disc and outer disc, stop disc, to tell outer disc be bending funnel-form, to tell interior disc be bending solid funnel-form, described stop disc is bending funnel-form, and centre circle structure is toward extension, internal thread is provided with in stop disc centre circle structure, the outermost of described disc is provided with stop disc and is enclosed within the external screw thread of bar cover.

tell the centre circle structure that stop disc extends out surface be provided with anti-skid structure.

described outer disc reduces gradually to two ends volume in the middle of bar.

advantage of the present invention is:

structure of the present invention is simple, can regulating weight arbitrarily, meets different people requirement, and by barbell cake is designed to five limits

shape, can effectively prevent barbell from disorderly rolling in the plane, interior disc and outer disc are designed to the funnel-form bent, be conducive to increasing the frictional force between disc and compatible degree, by the centre circle structure of stop disc toward extension, be conducive to spiral length of better stabilizing and increasing internal thread, and be convenient to rotation and tighten disc.

Accompanying drawing explanation

fig. 1 is structural representation of the present invention.

fig. 2 is the structure chart of stop disc of the present invention.

fig. 3 is construction profile of the present invention.

in figure, 1 be bar, 2 is bar covers, and 3 are interior discs, 4 are outer discs, 5 is stop discs, 6 are parts, 7 that stop disc extends are anti-skid structures, 8 is internal threads.

Detailed description of the invention

new-type barbell, comprise a bar 1, described bar 1 two ends are provided with bar cover 2, on described bar cover 2, cover has some dumbbell plates 3, 4 and 5, described disc 3, 4 and 5 is pentagon, described interior disc 3 is positioned on dumbbell bar cover 2, be close to the inwall of bar cover 2, described outer disc 4 is positioned on the bar cover 2 of bar 1, be close to interior disc 3, described stop disc 5 is also positioned on the bar cover 2 of bar 1, be close to outer disc 4, during use, first any disc is placed on bar cover 2, again stop disc 5 is enclosed within bar cover 2.

Claims

1. a new-type barbell, it is characterized in that comprising a bar, described bar two ends are provided with bar cover, bar puts and is provided with external screw thread, described bar puts cover some discs, disc surrounding of telling is pentagon, disc of telling is divided into interior disc and outer disc, stop disc, to tell outer disc be bending funnel-form, to tell interior disc be bending solid funnel-form, described stop disc is bending funnel-form, and centre circle structure is toward extension, internal thread is provided with in stop disc centre circle structure, the outermost of described disc is provided with stop disc and is enclosed within the external screw thread of bar cover.

2. a kind of new-type barbell as claimed in claim 1, the surface of the centre circle structure that the stop disc described in it extends out is provided with anti-skid structure.

3. a kind of new-type barbell as claimed in claim 1, outer disc described in it reduces gradually to two ends volume in the middle of bar.
