Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; it is apparent that the described embodiments are only some embodiments of the present utility model, not all embodiments, and that all other embodiments obtained by persons of ordinary skill in the art without making creative efforts based on the embodiments in the present utility model are within the protection scope of the present utility model.

Examples:

Referring to fig. 1-3, a bar bell with adjustable counterweight comprises a base 1, wherein a threaded rod 2 is fixedly connected to the upper end of the base 1, a plurality of uniformly distributed weights 3 are sleeved on the outer end of the threaded rod 2, a pressing point nut 4 is connected to the outer end of the threaded rod 2 in a threaded manner, the pressing point nut 4 is located on the upper side of the weights 3, a handle 5 is connected to the upper end of the threaded rod 2 in a threaded manner, the handle 5 is located on the upper side of the pressing point nut 4, a threaded hole 6 is formed in the lower end of the handle 5, and a hollow barrel 7 is installed between the base 1 and the inner wall of the handle 5.

In the use process of the scheme, in order to avoid the phenomenon that the moment and the gravity center distribution of the bar bell are changed because the length of the bar bell is changed after the weight of the bar bell is increased or decreased in the prior art, so that the performance of the bar bell cannot be maximally exerted, in the embodiment, the bar bell with the weight capable of being automatically adjusted and the moment and the gravity center distribution unchanged is designed, so that when a body-building sporter trains in different stages, only the weight is required to be increased or decreased in the bar bell, and the weight ends are not required to be increased or decreased at the left end and the right end;

when the novel self-balancing weight is used, firstly, a body-building sporter rotates the handle 5 to separate the handle 5 from the hollow barrel 7, then the hollow barrel 7 moves upwards until the hollow barrel 7 moves away from the threaded rod 2, the body-building sporter can sleeve weights 3 with different weight specifications at the outer end of the threaded rod 2 according to the required counter weights, if the weights 3 are not fully filled, the weights 3 can be screwed downwards through the pressure point nuts 4, so that the weights 3 are pressed and fixed, after the body-building sporter assembles the required counter weights, the hollow barrel 7 is sleeved at the outer end of the weights 3, then the handle 5 is screwed in the opposite direction, the counter weights can be replaced after the handle 5 is restored to the initial state, and the base 1 always keeps unchanged in the process.

Compared with the prior art, the balance weight of the bar bell can be increased or decreased while the length of the bar bell is not changed, so that the influence of the change of the gravity center distribution and the centrifugal effect on the benefit of a user in use is avoided because the length of the bar bell is changed after the balance weight ends are increased or decreased at the left side and the right side of the bar bell in the prior art.

Referring to fig. 1-3, weights 3 have different weight specifications and different thicknesses.

Further, the weight 3 has a smaller diameter than the inner diameter of the hollow shaft 7.

Further, the threaded rod 2 is mutually matched with the threaded hole 6, and the threaded rod 2 is mutually matched with the press point nut 4.

This scheme is in the use, when changing the counter weight, because be the shape setting between base 1 and the threaded rod 2, when making weight 3 cover establish on threaded rod 2, be difficult for rocking, weight 3 can be disc, square, other shapes such as rectangle, and the diameter of weight 3 is less than the inside diameter of hollow stack 7, make weight 3 be difficult for taking place wearing and tearing in hollow stack 7, the threaded rod 2 that can directly pass through base 1 upper end fixed connection under the state of filling weight 3 is rotatory screw up with screw hole 6, make all weights 3 be tightly fixed by base 1 and handle 5, if required configuration can't make weight 3 fill up hollow stack, the accessible is screwed down with the pressure point nut 4, make weight 3 compressed tightly fixedly, can't reciprocate, accomplish the configuration afterwards, when making the change counter weight, more convenient and fast.

Referring to fig. 1 to 3, the diameter of the base 1 is the same as the bottom diameter of the handle 5, and the diameter of the base 1 is the same as the outer diameter of the hollow barrel 7.

This scheme is in the use, after changing the counter weight, because the diameter of base 1 is the same with the bottom diameter of handle 5, and the diameter of base 1 is the same with the outside diameter of hollow stack shell 7 for closely laminate after the installation, be difficult for producing the gap and rock, the security when having increased the use.

Part of the components in this solution are also provided with the following alternatives:

1. Under the structural condition that the main body of the bar bell is hollow, the weights are not fixed by connecting the counter weights or the pressing point nuts in series by the screw, but stacked or fixed by other forms, for example, in the scheme, the connection of the two parts is a clamping connection, but the scheme can also be realized by the hinge connection, so the hinge connection is an alternative scheme.

2. After the internal weight 3 of the hollow barrel 7 is fully added, when the body building sportsman feels lighter in overall weight, the body building sportsman can screw out the base 1 through the hollow barrel 7, sleeve the fixed weight to the hollow barrel 7 and then screw up the base 1 to lock the fixed weight to increase the overall weight, the length of the fixed weight is the same as the length of the hollow barrel 7, and the weight of the fixed weight can be increased by increasing the thickness of the fixed weight.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
