Abstract

The utility model relates to an adjustable dumb bell, which comprises a rod body and at least a gravity body; a fixing device can selectively fix the gravity body to the two ends of the rod body. The rod body is provided with a guiding groove, the gravity body is provided with a fixing groove, and the fixing device is provided with a cotter body which is embedded in the guiding groove of the rod body and the fixing groove of the gravity body, so as to selectively fix the gravity body to the rod body. The utility model has the advantage that various different weights can be conveniently adjusted.

Description

Adjustable dumbbell

The utility model relates to a kind of dumbbell, particularly a kind of adjustable dumbbell.

The tradition dumbbell all has fixed weight, so the user must prepare just convenient use of dumbbell that a cover has various Different Weight.

Because many shortcomings of the general dumbbell of using always, the purpose of this utility model is to provide a kind of adjustable dumbbell that can conveniently adjust various Different Weight.

Above-mentioned purpose of the present utility model is realized by following technical scheme.

A kind of adjustable dumbbell includes a body of rod and at least one gravity body; It is characterized in that: a fixture optionally is fixed to gravity body the two ends of the body of rod.

Except that above-mentioned essential features, in specific implementation process, also can replenish following technology contents:

This body of rod is established a guide groove, and gravity body has a holddown groove, and this fixture has a key and is embedded in the holddown groove of the guide groove of the body of rod and gravity body, gravity body is fixed to the two ends of the body of rod.

One carriage release lever is fixed on this key.

One jacket casing is located on this carriage release lever, and sheathed one is forced to the spring of the body of rod with sleeve between the head of sleeve and carriage release lever.

This body of rod has a shifting chute that supplies carriage release lever to be embedded.

It comprises that more one supports the substrate of gravity body.

Advantage of the present utility model is: can conveniently adjust various Different Weight.

For further specifying structure of the present utility model, feature and practical purpose thereof describe in detail as the back with the following example and accompanying drawing:

Description of drawings:

Fig. 1 is a stereogram of the present utility model;

Fig. 2 is an exploded view of the present utility model:

Fig. 3 is an end-view of the present utility model; And

Fig. 4,5 overlooks the action schematic diagram for part of the present utility model.

Adjustable dumbbell of the present utility model please cooperate and consult Fig. 1 to shown in Figure 4, and this adjustable dumbbell comprises: a substrate 10 does not have a plurality of partition walls 12 forming a plurality of grooves 11, and can be embedded gravity body 20; Each gravity body 20 respectively has a groove 21 and a holddown groove 22, these groove 21 each tool one top openings 23, and the width of each holddown groove 22 is greater than the width of groove 21; One body of rod 30, two ends 31 can embed groove 21 from top to bottom, and a plurality of caulking grooves 33 of two ends 31 each tool and fin 32, for being embedded each gravity body 20, and respectively have a guide groove 34 for a key 40 sliding establishing; A shifting chute 36 is respectively established at the body of rod 30 two ends 31 and guide groove 34 is connected, and a plurality of depression 37 and shifting chute 36 be connected, and with respect to the number of gravity body 20 and establish; A baffle plate 39 can respectively be established for blocking gravity body 20 in this inboard, body of rod 30 two ends; One carriage release lever 41 inserts each shifting chute 36 and the solid screw 42 to key 40 of spiral shell, and key 40 can be moved with respect to the body of rod 30; One sleeve 45 is located on each carriage release lever 41, and it has an end 46 can embed each depression 37; One spring 44 is located on each carriage release lever 41, and is located between the head 43 of sleeve 45 and carriage release lever 41, so that end 46 embeddings of sleeve 45 are forced into each depression 37 and key 40 can be fixed to the desired location place of the body of rod 30.

Mode of operation of the present utility model please cooperates Fig. 4 again, and shown in 5, key 40 can be moved that bar 41 moves and holddown groove 22 the insides that embed one or more gravity body 20.And sleeve 45 must antagonistic spring 44 and up draws, and makes the end 46 of sleeve 45 be separated from each depression 37 and just key 40 can be moved to needed position with respect to the body of rod 30.And after key 40 embeds one or more gravity body 20, sleeve 45 is bled off, make the end 46 of sleeve 45 be forced into corresponding depression 37 the insides again, and can once more key 40 be fixed to the desired location place of the body of rod 30.

At this moment, when key 40 embeds the holddown groove 22 of two gravity body 20 (Fig. 5), and when the body of rod 30 is up carried, this body of rod 30 can be mentioned this two gravity body 20 in passing, the gravity body 20 that two other key 40 is provided with embedding then can not be raised, and makes to have only two gravity body 20 can be fixed to the body of rod 30 1 ends.And when key 40 embeds the holddown groove 22 of four gravity body 20 (Fig. 4), and when the body of rod 30 was up carried, this body of rod 30 can be mentioned these four gravity body 20 in passing, made four gravity body 20 all can be fixed to the body of rod 30 1 ends.So can select one or more gravity body 20 to be fixed to one or two ends of the body of rod 30.
