Description

Multifunctional barbell

technical field

The invention belongs to the technical field of training equipment for enhancing the growth of muscles or joints of the human body, in particular to a multifunctional barbell.

Background technique

The invention with the application number of 03272188.9 discloses a two-in-one barbell dumbbell, which includes a bell bar and a bell head. Dumbbells for independent use. When the bell bar is connected with the two dumbbells as the bell head, the two-in-one barbell dumbbell can be used as a barbell; after the bell bar is removed, the dumbbell as the bell head can be used independently. The shortcomings of this solution are: (1) It needs to be equipped with a bell bar to assemble the dumbbells at both ends into a barbell; (2) When assembling, it is necessary to rotate the dumbbell in hand to fix it with the bell bar, which is laborious; (3) ) The weight of the dumbbell is heavy, and it is easy to bend, deform or even damage the connection between the dumbbell and the bell bar; (4) The purpose of adjusting the weight of the barbell can only be achieved by adjusting the weight of the dumbbells at both ends; (5) The horizontal length of the barbell is only This can be achieved by adjusting the length of the bell bar.

The invention and creation with application number 201420407752.5 discloses a dumbbell, comprising a first dumbbell bar and a second dumbbell bar, one end of the first dumbbell bar is provided with a threaded groove along the length direction of the first dumbbell bar, and one end of the second dumbbell bar is The thread is installed in the threaded groove, a number of dumbbell plates are movably sleeved on the first dumbbell rod and the second dumbbell rod, and a clamping block is arranged on the outer ends of the first dumbbell rod and the second dumbbell rod. Both are provided with a fixing device. In this solution, the dumbbell bar is split from the middle when adding and removing the dumbbell bar, and the increase or decrease is performed from the middle of the dumbbell bar, so that the operation of adding and removing the dumbbell bar becomes simpler compared with the prior art. The shortcomings of this solution are: (1) When adding and reducing the dumbbell plate, the first dumbbell bar and the second dumbbell bar need to be rotated and separated, and the first dumbbell bar and the second dumbbell bar are both fixed with dumbbell plates, which leads to a relatively long operation. It is laborious; (2) the weight of the dumbbell is relatively large, and the connection between the first dumbbell bar and the second dumbbell bar is bent, deformed or even damaged.

SUMMARY OF THE INVENTION

The purpose of the present invention is to overcome the deficiencies of the prior art and provide a multifunctional barbell, which is not only convenient for adding and removing dumbbell pieces, but also can be used as a barbell after being spliced with each other, and the connection of each dumbbell is not easily damaged.

In order to achieve the above purpose, the technical solution of the present invention is as follows: a multifunctional barbell, characterized in that: it is formed by splicing several dumbbells; the dumbbell includes a first bell bar and several dumbbell pieces, and the dumbbell pieces are locked by a locking nut Close to both ends of the first bell bar, a channel for the first bell bar to pass through is opened between the center of the dumbbell plate and the edge of the dumbbell plate, and the channel is L-shaped; the adjacent dumbbells are connected to form a barbell through the second bell bar , the second bell bar is located between the dumbbell plates of adjacent dumbbells, and the dumbbell plates are provided with through holes for the second bell bar to pass through; when the barbell is split into dumbbells for use, the second bell bar is located at the dumbbells at both ends of the same dumbbell between the plates to prevent the dumbbell plate from falling off the first bar.

In this solution, the dumbbell plate is added to the first bell bar by inserting through the channel, and then the locking nut is tightened. Due to the L-shaped channel, once the lock nut is loose, the dumbbell plate will not easily separate from the first bar. In order to prevent the occurrence of the occurrence of the dumbbell plate slipping due to the loosening of the locking nut, the dumbbell plate is also provided with a through hole, and the second bell bar is fixed in the through hole on the dumbbell plate. It is impossible to fall off the first bell bar.

When used as a dumbbell, the exerciser's palm is inserted between the first bell bar and the second bell bar, which is not easy to slip off and increases safety.

When you need to increase or decrease the dumbbell plate, pull the second bell bar out of the through hole and loosen the lock nut. The traditional operations for adding barbell plates are: unscrew the lock nut, lift the bar with the heavier dumbbell plate, insert the dumbbell plate laterally into the bar, and screw on the lock nut. In this solution, only the second bell bar with lighter mass is withdrawn from the through hole, the dumbbell plate is inserted vertically into the bell bar, the locking nut is tightened, and the second bell bar is inserted. Compared with the traditional method, this solution is relatively convenient and labor-saving.

When several dumbbells need to be spliced into a barbell, the second bell bar is moved laterally so that the second bell bar is inserted into the through hole of the adjacent dumbbells, and the second bell bar is used to fix the two adjacent dumbbells. The advantages of this connection method are as follows: (1) The connection between adjacent dumbbells can be realized by only turning the second bell bar with a lighter mass, which is convenient and labor-saving, and does not require an additional bell bar; (2) Dumbbell plates Both the second bell rod and the second bell rod are thicker, can bear a large weight, and are not easily deformed and damaged. In addition, when the dumbbells are spliced into a barbell, if the dumbbell plate at the end of the barbell is not separately inserted into a second bar and the channel is straight, the dumbbell plate at the end of the barbell may slip off. In the present application, however, the channel is L-shaped, and the dumbbell plate at the end of the barbell is less likely to slip.

As a further technical solution, the dumbbell plate is provided with 3 through holes in total. The 3 through holes are convenient for the second bell bar to be inserted laterally when the adjacent dumbbell plates are rotated at a certain angle.

As a further technical solution, a limit plug is arranged in the channel. When the dumbbells are spliced into a barbell, the stopper can further prevent the dumbbell plate at the end of the barbell from slipping.

As a further technical solution, the limiting plug is L-shaped. The L-shaped limit plug corresponds to the shape of the channel, which can enhance the firmness of the combination between the limit plug and the channel.

As a further technical solution, the second bell bar and the through hole of the dumbbell plate are connected by threads. Threaded connection is easy to use.

As an alternative technical solution, the through hole of the dumbbell plate is provided with a groove, and both ends of the second bell bar are provided with a plurality of raised parts; when the dumbbell plate is located at one end of the second bell bar, the raised parts are stuck in the groove. This solution makes the second bar move more quickly laterally between the dumbbell plates.

To sum up, the present invention has the advantages of novel structure, safety and reliability, not only is it convenient to add and remove dumbbell pieces, but also can be used as a barbell after being spliced with each other, and the connection of each dumbbell is not easily damaged.
