Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1 to 3, a spring-grip dumb-bells according to a preferred embodiment of the present invention can improve the muscle exercise effect of the palm.

Based on the above technical scheme, the embodiment provides a spring-grip, including fixed column 100 and four grips 200 of setting on fixed column 100 circumference, wherein, fixed column 100 is used for fixed four grips 200, and fixed column 100, grip 200 are made by metal to guarantee the intensity of this spring-grip.

Specifically, the middle of each grip 200 is hinged to the fixing post 100, so that the grips 200 can rotate relative to the fixing post 100, and the first end of each grip 200 is provided with a holding portion 210 for fingers to hold, so that the holding portion 210 of each grip 200 can be far away from or close to the fixing post 100.

Specifically, a spring fixing plate 300 is disposed in the middle of the second end of each handle 200, and a spring 400 is fixedly connected between the spring fixing plate 300 and the second end of each handle 200. The spring fixing plate 300 is used for fixing the spring 400, the grips 200 and the fixing posts 100 form a lever structure, when the fingers grip each grip 200, so that the grip portion 210 of the grip 200 is close to the fixing post 100, the spring 400 pulls the grip portion 210 away from the fixing post 100 through the lever structure, and further exercises the muscle of the hand.

Compare in the spring-grip that only has two grips, this spring-grip has four grips, and four grips all can be through finger, palm cooperation clenching, when holding the handle and clenching through the finger, the muscle intensity of finger can be improved under the support of grip to the end of finger. Compared with the hand-muscle developer only provided with two grips, the strength of the fingers can be fully exercised through the four grips, and the muscle exercising effect of the hands is improved.

Preferably, four through holes 310 are uniformly formed on the spring fixing plate 300, and the end of the spring 400 passes through the through holes 310 to be fixedly coupled to the spring fixing plate 300. Wherein, the end of the spring 400 is bent in the through hole 310, the end of the spring 400 is bent to form a connection structure buckled with the through hole 310, and the end of the spring 400 forms a ring structure around the through hole 310, thereby improving the stability of fixing the spring 400.

Preferably, a first notch 220 is formed at the second end of each handle 200, and a first pin 221 is inserted into the first notch 220, wherein the first pin 221 is a bolt structure, and a nut is connected to the first pin 221, so as to stably connect the first pin 221 with the first notch 220.

Specifically, the end of the spring 400 is fixedly connected to the first pin 221, and the end of the spring 400 is bent to surround a ring-shaped structure around the first pin 221, so as to improve the connection stability of the spring 400.

Preferably, a second recess 230 is disposed in the middle of each handle 200, and a second bolt 231 is inserted into the second recess 230, wherein the second bolt 231 is a bolt, a nut is connected to the end of the second bolt 231 through a screw thread, and the second bolt 231 can be fixedly connected to the second recess 230 through the nut.

Specifically, as shown in fig. 3, the fixing post 100 is provided with a protrusion 110 capable of being inserted into the second notch 230, a second pin 231 is inserted between the protrusion 110 and the handle 200, and the protrusion 110 and the handle 200 can be hinged by the second pin 231, so that the handle 200 can rotate relative to the fixing post 100.

Preferably, a curved surface portion 211 for cooperating with fingers is provided on a side surface of the holding portion 210 away from the fixing column 100, and the curved surface portion 211 has a curved surface cooperating with fingers, so that the curved surface portion 211 can cooperate with fingers stably, thereby improving stability of the curved surface portion 211 when the finger is assigned with a hand.

To sum up, the utility model discloses simple structure can improve finger, palm exercise effect everywhere, has improved the exercise effect of spring-grip to hand muscle.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
