Description

Five-stage pressure adjustable grip

technical field

The utility model relates to a fitness equipment, in particular to an improved grip with adjustable pressure.

Background technique

Gripper is a kind of fitness equipment designed according to the shape of human hand. It is small and light, easy to carry, and there is no restriction when using it. It can exercise hand strength at any time, relieve fatigue, make muscles strong, and enhance blood circulation. Long-term use, It is helpful to prevent rheumatoid arthritis, etc. It is an essential small fitness equipment for exercising and fitness. In many physical examinations in China, grip strength is a compulsory item. Therefore, the grip strength device is basically an indispensable equipment for middle school students to exercise grip strength. The existing grip strength device provides elastic damping structure that cannot be changed from the beginning to the end. , but for different groups of people, different ages, different genders, and different grip strengths, it is difficult for the same grip to be used by such a large group. In this way, a pressure-adjustable grip is needed. When the pressure cannot be satisfied, the pressure can be changed by adjusting the gripper itself to reach the required range again; in addition, after the athletes exercise for a period of time, the grip strength of their hands is exercised and increased, which also needs to be adjusted to change The size of the grip strength of the gripper is re-applicable to the user, so that the user has a greater improvement. All of these require a pressure-adjustable gripper to satisfy, instead of discarding it and buying it again, causing waste.

Utility model content

In view of the many shortcomings and limitations of the above-mentioned grippers, the utility model designs a gripper that can change the pressure through its own structural adjustment, to meet the needs of groups with different grip strengths for exercise, and to meet the needs of athletes when hand strength increases. stressful demands.

The utility model is realized through the following technical solutions: the five-stage pressure-adjustable grip includes two mutually symmetrical handles, and also includes a pivot joint that serves as the fulcrum for pivoting the two handles and provides elastic damping, and the pivot head is provided with Two connectors, one end of each of the two handles is connected to the two connectors on the pivot head; the pivot joint is provided with a semicircular clamping hole, and a semicircular clamping hole with the same inner diameter as the clamping hole is also provided. Bolt rod, the bolt rod is made of elastic material, the front end of the bolt rod is set as a slope for easy clamping into the clamping hole, the inside of the bolt rod is provided with a wall ladder whose thickness gradually increases from the front end to the back, and the wall ladder has at least Three sections, after the bolt rod is clamped in the clamping hole, it can move relative to the clamping hole.

The following is a further elaboration to the above-mentioned technical scheme:

Protruding ridges are provided on the front and rear arcs of the bolt rod.

The wall ladder provided inside the bolt rod is provided with 5 sections.

The elastic material used to make the bolt is plastic elastic material.

The handle and pivot joint are injection molded into one body.

The bolt rod, the wall ladder provided on the bolt rod, and the protruding ridges provided on the front and rear arcs of the bolt rod are also injection molded into one body.

The other ends of the two symmetrical handles connected to the pivot joints are respectively provided with a protective glove.

The beneficial effects of the utility model are: the pivot joint is provided with a semicircular clamping hole, and a semicircular bolt rod with the same inner diameter as the clamping hole is also provided. The bolt rod is made of elastic material, and the bolt rod is provided with a It is a wall ladder with increasing thickness from the front end to the rear. The wall ladder has five sections. After the bolt rod is clamped in the clamping hole, it can move relative to the clamping hole. Through this structure, as long as the position of the bolt rod in the pivot joint is moved , so that the parts of the wall ladder with different thicknesses are clamped in the pivot joint, the pressure between the two handles can be adjusted, which is convenient for people with different strengths to use.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

As shown in Figures 1 and 2, the five-stage pressure-adjustable grip includes two symmetrical handles 1, and also includes a pivot joint 2 that serves as the pivot point of the two handles 1 and provides elastic damping. There are two connectors, each of the two handles 1 is connected to the two connectors located on the pivot head 2 with one end, and the pivot joint is also provided with a semicircular clamping hole; the handle 1, the pivot The joint 2 is injection molded into one body; the other ends of the two symmetrical handles 1 connected to the pivot joint are each covered with a protective glove.

As shown in Figure 3 and Figure 4, the five-stage pressure adjustable grip is also provided with a semicircular bolt 3 with the same inner diameter as the clamping hole. The bolt 3 is made of elastic material, and the front end of the bolt 3 is set to facilitate installation. Clamped into the clamping hole in a slope shape, the inside of the bolt bar 3 is provided with a wall ladder with increasing thickness from its front end to the rear, and the wall ladder is provided with 5 sections. After the bolt bar 3 is clamped in the clamping hole, it can be connected with the clamping hole. Relative movement occurs; the front and rear arcs of the bolt rod 3 are provided with raised ridges; the elastic material made of the bolt rod 3 is a plastic elastic material; the bolt rod 3, bolt rod The wall ladder provided on the 3 and the bolt bar 3 are provided with raised ridges on the arcs of the front end and the rear end, which are also injection molded into one.

As shown in Figure 3, when adjusting the pressure, push the bolt rod 3 clamped in the clamping hole by hand, according to the pressure of the two handles 1 required, when pushing the bolt rod 3, let the wall ladder The position of the bolt rod 3 is left in the clamping hole; when the pressure of the required two handles 1 is relatively large, the position of the bolt rod 3 where the thicker wall ladder is located is left in the clamping hole, and the left is The position where the thickness of the wall ladder in the bolt rod 3 is relatively large increases the outward elastic force of the two handles 1, and requires a relatively large force to squeeze the bolt rod 3 to squeeze and deform in the middle; when the required two handles 1 When the pressure is small, the position of the bolt rod 3 where the wall ladder with a smaller thickness is located is left in the clamping hole, and the position of the wall ladder with a smaller thickness in the bolt rod 3 is left, so that the outward movement of the two handles 1 is reduced. The elastic force only needs a small extrusion force and the bolt rod 3 will be squeezed and deformed in the middle; through the above method, the pressures of different sizes required between the two handles 1 can be exchanged.

According to the disclosure and teaching of the above specification, those skilled in the art to which the present utility model belongs can also make appropriate changes and modifications to the above embodiment. Therefore, the utility model is not limited to the specific implementation manners disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present utility model.
