Description

Barbell

Technical field

The utility model belongs to sports equipment field, is specifically related to a kind of barbell.

Background technology

Current barbell is two ends multi-disc disc being fixed on screwed bar with nut, dismounting is bothersome, and particularly when the disc used is less, the rotating cycle of nut is more, lose time very much during dismounting, but also there is the inflexible defect of weight combinations.

Summary of the invention

The purpose of this utility model is bothersome but also there is the inflexible problem of weight combinations in order to solve current barbell dismounting, and provide a kind of barbell, its technical scheme is as follows:

A kind of barbell, it comprises bar and disc, is respectively provided with the disc of more than two panels or two panels at the two ends of bar, and the end face outside of every sheet disc is provided with identical screw, and screw hole depth is 1/2nd of disc thickness; The inner side end of the every sheet disc except the two panels disc except being positioned at inner side is provided with the screwed pipe corresponding with the screw in the end face outside of disc, and adjacent disc is connected by screwed pipe with between disc; In each screwed pipe, be provided with the balancing weight coincide with space in screwed pipe, the balancing weight in each screwed pipe is all be set with by the sub-balancing weight of multilayer to form; The screw being positioned at outermost two panels disc is provided with plug, and plug is connected with disc by screw thread; The outer face of plug is provided with two or more circular hole, is used for doing attacker's easy disassembly plug; Bar is connected and composed by three knot bars successively head and the tail, be positioned at the middle long 15-18 centimetre of a knot bar, screw rod is provided with at the two ends being positioned at a middle knot bar, be respectively arranged with the screw adapted to the screw rod being positioned at middle knot bar two ends at the phase near-end of the sub bar being positioned at both sides, three knot bars are connected by screw rod; Screw rod is respectively arranged with at the phase far-end of the sub bar being positioned at both sides, the inner side end of two panels disc being positioned at inner side is provided with the screw adapted with the screw rod of the phase far-end of the sub bar being positioned at both sides, and the two panels disc being positioned at inner side is connected by the phase far-end of screw rod with the sub bar being positioned at both sides; Be provided with the screw adapted to the screw rod being positioned at middle knot bar two ends in the center of two plugs, two plugs can be connected to be positioned at middle knot bar two ends to be assembled into dumbbell use.

The beneficial effects of the utility model are: easy accessibility, save time, and weight can matched combined flexibly, can also be assembled into dumbbell and use.
