Description

Technical Field

[0001] The utility model relates to the technical field of grip trainers, in particular to an adjustable grip trainer. Background Art

[0002] A grip trainer is a device specifically designed to enhance the muscle strength of the hand and forearm. By providing opposing resistance, it effectively exercises the muscles of the hand, improving grip strength and the overall strength of the arm. A grip trainer usually consists of one or more springs, and users exercise the muscles of the hand and forearm by holding and compressing these springs with their hands. The design of the grip trainer can be adjusted according to the user's hand size and strength level to ensure effective use by different users. During exercise, users need to hold the grip trainer in the correct posture and squeeze it with appropriate force. Through continuous training, the strength and endurance of the hand can be significantly improved. Using a grip trainer can not only strengthen the muscles of the hand and forearm, but also promote blood circulation, relieve hand fatigue and prevent related diseases. In addition, regular use of a grip trainer can also help improve hand-eye coordination and increase the efficiency of work and daily life.

[0003] However, the design of some existing grip trainers lacks a precise adjustment mechanism and cannot adapt to the strength levels and progress speeds of different users. The inability to adjust the starting resistance and progression gradient means that trainers can only practice at a fixed strength level, which undoubtedly reduces the flexibility and adaptability of training. In addition, if the resistance level of the trainer is too low or too high, it can make it difficult for beginners to get started or prevent advanced users from getting enough challenges, thus affecting the training effect and user satisfaction. Therefore, in view of the above deficiencies, an adjustable grip trainer is proposed to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an adjustable grip trainer, aiming to improve the problem that some grip trainers in the prior art cannot effectively adjust the threshold of grip strength.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] Adjustable grip strength trainer, comprising two grips, the tops of both of the two grips are fixedly connected with rotating frames, a fixed shaft is rotatably connected inside both of the two rotating frames, the tops of both of the two rotating frames are fixedly connected with fixing plates, the tops of both of the two fixing plates are fixedly connected with fixing blocks, a plurality of fixing frames are fixedly connected inside both of the two fixing blocks, clamping columns are slidably connected inside the plurality of fixing frames, fixing rings are fixedly connected to the outsides of the plurality of clamping columns, adjusting springs are sleeved on the outsides of the plurality of clamping columns, a pulling plate is fixedly connected to the top of every five clamping columns, a plurality of sliding grooves are formed inside both of the two fixing blocks, a plurality of grip springs are arranged on the adjacent sides of the two fixing blocks, two clamping grooves are formed inside the plurality of grip springs, and a counting assembly for calculating force is arranged on the tops of the two rotating frames;

[0007] As a further description of the above technical solution:

[0008] The counting assembly includes an arc-shaped sector ring, the right side of the arc-shaped sector ring is fixedly connected to the left side of one of the rotating frames, a sliding plate is fixedly connected to the left side of the arc-shaped sector ring, a pointing block is fixedly connected to the front side of the sliding plate, and an arc-shaped frame is fixedly connected to the right side of the other rotating frame;

[0009] As a further description of the above technical solution:

[0010] The outside of the grip spring is slidably connected inside the fixing block, and the outside of the clamping column is slidably connected inside the clamping groove;

[0011] As a further description of the above technical solution:

[0012] The outside of the fixing ring is slidably connected inside the fixing frame, and friction lines are arranged on the outside of the grip;

[0013] As a further description of the above technical solution:

[0014] One end of the adjusting spring is fixedly connected to the top side inside the fixing frame, and the other end of the adjusting spring is fixedly connected to the top of the fixing ring;

[0017] As a further description of the above technical solution:

[0018] The outer portion of the sliding plate is slidably connected to the inner portion of the arc frame, and the outer portion of the arc-shaped sector ring is slidably connected to the inner portion of the arc frame;

[0019] As a further description of the above technical solution:

[0020] A force scale is arranged on the top of the arc frame.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the present invention, the number of grip springs can be adjusted. When the user needs to adjust the difficulty of training, the pull plate can be pulled upward to cause the clamping column and the fixing ring to move. At this time, the adjustment spring will be compressed, causing the clamping column to disengage from the clamping groove inside the grip spring. In this way, the user can easily add or remove grip springs to adjust the strength threshold of grip training. This design makes the grip trainer suitable for users with different strength levels, increasing the applicability and flexibility of the device.

[0023] 2. In the present invention, when the user pinches the grip for training, the rotating frame will rotate around the fixed axis, and this rotation is converted into the sliding of the sliding plate in the arc frame through the arc fan ring. Since the front side of the sliding plate is fixedly connected with a pointing block, the position change of the pointing block intuitively reflects the user's grip strength. The user can understand his grip strength in real time by observing the position of the pointing block on the arc frame and the corresponding scale. This instant feedback mechanism helps the user monitor the training effect, adjust the training intensity, and ensure the safety and effectiveness of the training. BRIEF DESCRIPTION OF THE DRAWINGS

The adjusting spring 9 is used to provide elastic force so that the card columns 7 can be separated from the card slots 13 when needed. A pull plate 10 is fixedly connected to the tops of every five card columns 7, and the pull plate 10 is used to pull the card columns 7 to move so as to adjust the number of grip springs 12. Multiple sliding grooves 11 are provided inside the two fixed blocks 5;

[0034] On the adjacent sides of the two fixed blocks 5, there are multiple grip springs 12. The chute 11 is used to accommodate and guide the movement of the grip springs 12. The outside of the grip springs 12 is slidably connected to the inside of the fixed blocks 5. One end of the grip spring 12 is fixedly connected to the inside of one of the fixed blocks 5, and the other end of the grip spring 12 is fixedly connected to the inside of the other fixed block 5.
