Abstract

The utility model discloses a sports fitness device, and relates to fitness equipment. The sports fitness device comprises a handle and a plurality of bell bodies in the similar shape at two sides of the handle. Threaded holes are formed at two ends of the handle and the center of one side of each bell body, a threaded column matched with the threaded hole is arranged at the center of the other side of each bell body, and the handle and the bell bodies are connected through the threaded columns and the threaded holes in a threaded matching mode. The plurality of bell bodies are connected with one another through the threaded columns and the threaded holes in a threaded matching mode, and soft rubber is arranged at contact positions of two ends of the handle and the bell bodies. According to the sports fitness device, the handle is connected with the plurality of bell bodies in sequence through threads, and therefore bell bodies with corresponding weights are directly loaded or unloaded to increase the weight or decrease the weight, and the operation is simple and convenient. Due to threaded connection among bell bodies on two sides of the handle, extra parts can not stretch out of the outer sides of the bell bodies, and people can not be scratched by dumbbells which are placed on the ground arbitrarily.

Description

A kind of physical fitness device

Technical field

The utility model relates to a kind of body-building apparatus, particularly a kind of physical fitness device.

Background technology

Present increased weight dumbbell consists essentially of handle and bell body, establishes screw thread at the handle two ends, the bell body of reciprocity quantity is located in the handle two ends respectively, and establishes a fastening bolt in outermost end, avoids the bell body to come off.This dumbbell need be backed out the fastening bolt on both sides earlier in weightening finish or loss of weight, and then equity lays down part bell body, tightens fastening bolt at last again, complex steps, very trouble; When producing, do handle very long because the handle of dumbbell in order to increase a plurality of bell bodies, makes, so that after assembling, two ends meeting exposed portions serve handle, when generally people are without dumbbell, all be that it at will is placed on the ground, be easy to be scratched because of carelessness when walking by exposed portions serve.

The utility model content

At above-mentioned the deficiencies in the prior art part, the utility model provides a kind of physical fitness device, has solved the problem that above-mentioned prior art exists effectively.

To achieve these goals, the technical solution adopted in the utility model is: a kind of physical fitness device, comprise the similar bell body of several piece shape on handle and handle both sides, and described handle two ends and bell body are equipped with screwed hole in the center on one side; Be provided with the threaded post that is complementary with screwed hole in bell body another side center, handle is connected with the threaded post threaded engagement by screwed hole with the bell body, also be connected with the threaded post threaded engagement by screwed hole between the several piece bell body, handle two ends and bell body contact position have soft rubber.

Further, the protection piece that has been threaded on the described outermost bell body, protection piece inboard is provided with the software rubber layer;

Further, the hole depth of described screwed hole equates with the post height of threaded post.

Compared with prior art, the beneficial effect of this utility model: the utility model is threaded with several bell bodies successively by handle, and when weightening finish or loss of weight, the bell body that only need directly unload corresponding weight gets final product, and is very simple and convenient like this; Because between the bell body of handle both sides is to be threaded, the external side of bell does not just have the redundance that stretches out like this, and the dumbbell that people just can arbitrarily be placed on the ground scratches.

Description of drawings

Fig. 1 is the schematic perspective view of the utility model embodiment;

Fig. 2 is the perspective exploded view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Embodiment:

Referring to Fig. 1 and Fig. 2, this safe dumbbell for convenience detach comprises the bell body 2 that handle 1 is similar with the several piece shape on handle 1 both sides, and described handle 1 two ends and bell body 2 are equipped with screwed hole 4 in the center on one side; Be provided with the threaded post 5 that is complementary with screwed hole 4 in bell body 2 another side centers; handle 1 is connected with threaded post 5 threaded engagement by screwed hole 4 with bell body 2; also be connected with threaded post 5 threaded engagement between the several piece bell body 2 by screwed hole 4; protection piece 3 has been threaded on described outermost bell body 2; and protection piece 3 inboards are provided with the software rubber layer; also be provided with same threaded post 5 on the protection piece 3, handle 1 two ends and bell 2 body contact positions have soft rubber.

Screwed hole 4 hole depths on above-described handle 1 and the bell body 2 are with bell body 2 and protect the threaded post 5 posts height on the piece 3 to equate.

Be threaded successively with several bell bodies 2 by handle 1, when weightening finish or loss of weight, the bell body 2 that only need directly unload corresponding weight gets final product, and operates very simple and convenient like this; Because between the bell body 2 of handle 1 both sides is to be threaded; bell body 2 outsides just do not have the redundance that stretches out like this; the dumbbell that people just can arbitrarily be placed on the ground scratches, and outermost protection piece 3 can be protected screwed hole 4, is contained on the bell body 2 to make this dumbbell more attractive in appearance.

The above only is the detailed description of the utility model preferred embodiment and graphic, is not to be used for limiting the utility model, and the embodiment or the approximate construction of all similar variations of doing according to creation spirit of the present utility model all should be contained among the utility model.
