Description
Technical field
The utility model relates to field of exercise equipment more particularly to a kind of straight forming hollow tube to fill dumbbell, barbell.
Background technique
What existing dumbbell or barbell were made of the head and handle of dumbbell or barbell mostly, and dumbbell head or barbell head are
By solid round steel or machine-shaping is cast, then reaches the requirement of different weight by changing the size of round steel or casting,
However the dumbbell of casting structure or barbell are not sufficiently strong and be easily damaged, the cutting of round steel and post-production forming cost are very
It is high.Meanwhile the cost of dumbbell or barbell that the round steel or casting of same weight are made into can be much higher than containing useless with sand or iron sand etc.
Expect the dumbbell or barbell being filled into.
Utility model content
The purpose of the utility model is to overcome above-mentioned limitations, solve existing drawback, thus provide a kind of simplified dumbbell or
The production procedure of person's barbell greatlys save the manufacturing cost of dumbbell or barbell, improves production efficiency, saves social resources
Straight forming hollow tube fills dumbbell, barbell.
The purpose of this utility model is to be achieved through the following technical solutions: a kind of straight forming hollow tube filling is mute
Bell, barbell, including mid-handle, mid-handle cover on center shaft, and mid-handle both ends are equipped with inner sidewall, and inner sidewall covers in
In mandrel, inner sidewall side is equipped with hollow pipe, is equipped with support frame, support frame and hollow inside pipe wall and central axis phase in hollow pipe
Even, hollow pipe outer end is equipped with lateral wall, is equipped with weight filler in hollow pipe.
Preferably, according to dumbbell demand of different shapes, hollow pipe is cut by the hollow tube for pulling straight out respective shapes
The segment for taking into some length is made.If the shape of hollow pipe is round, rectangular, hexagon, dodecagon or special-shaped shape changeable
Deng.
Preferably, support frame is equipped with multiple supporting ribs, and supporting rib end and hollow inside pipe wall weld or pass through screw
Fixed, support frame central part is fixed with central axis by welding or screw connection.
Preferably, bushing or bearing are equipped between mid-handle and central axis.
Preferably, multiple side handles are equipped between inner sidewall, side handle is fixed with inner sidewall by welding or screw, side
Handle is evenly distributed on around mid-handle.
Preferably, hollow tube outer surface and inner sidewall, lateral wall are enclosed with rubber layer or layer of polyurethane.
Preferably, weight filler includes cement, sand, iron sand or other mass.
Preferably, inner sidewall and lateral wall are made of laser cutting or pressed sheet.
In conclusion compared with the prior art, the utility model has the following advantages: simplifying the production of dumbbell or barbell
Process greatlys save the manufacturing cost of dumbbell or barbell, improves production efficiency, saves social resources.

Specific embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail, which is only used for explaining the utility model, does not constitute the restriction to scope of protection of the utility model.
Embodiment 1: a kind of straight forming hollow tube as shown in Figure 1 fills dumbbell, barbell, including mid-handle 1, in
Between 1 set of handle on central axis 2,1 both ends of mid-handle are equipped with inner sidewall 3, and mid-handle 1 and inner sidewall 3 pass through welding or spiral shell
Silk is fixed, 3 sets of inner sidewall on central axis 2,3 side of inner sidewall be equipped with hollow pipe 4, inner sidewall 3 and hollow pipe 4 by welding or
Screw is fixed, and support frame 5 is equipped in hollow pipe 4,5 sets of support frame are connected with hollow pipe 4 and central axis 2, and 4 outer end of hollow pipe is equipped with
Lateral wall 6, hollow pipe 4 are fixed with lateral wall 6 by welding or screw.Support frame 5 is equipped with multiple supporting ribs 7,7 end of supporting rib
It welds or is screwed with 4 inner wall of hollow pipe in portion.The central part and central axis 2 of supporting rib 7 weld or are consolidated by screw
Fixed to be connected, inner sidewall 3 and lateral wall 6 are made of laser cutting or pressed sheet.Hollow pipe 4 is by directly taking the molding hollow pipe of extraction
Material cuts a certain length and is made.The center line of hollow pipe 4 is overlapped with the center line of central axis 2, in the collective effect of support frame 5
Under, increase the stability and intensity of dumbbell, barbell entirety.By in hollow pipe 4 be added different weight breeding filler come
It realizes the dumbbell and barbell of different weight, while obtaining the effect of the consistency of the dumbbell or barbell of different weight in shape.
Bushing or bearing are equipped between mid-handle 1 and central axis 2, when lifting the dumbbell or barbell, mid-handle 1 is remained stationary, and is kept away
Exempt from discomfort caused by the friction of mid-handle 1 and palm, meanwhile, increase the length of mid-handle 1 and central axis 2, can make
For barbell use.
Embodiment 2: it is solid by welding or screw that multiple side handles 8, side handle 8 and inner sidewall 3 are equipped between inner sidewall 3
