Description

Technical Field

[0001] This utility model relates to the field of sports exercise technology, and in particular to a forearm trainer. Background Technology

[0002] A forearm trainer is a device specifically designed for strength training of the forearm muscle groups. It is mainly used to exercise the biceps, triceps, and forearm flexor muscles, helping to improve grip strength, wrist strength, and overall forearm strength.

[0003] Existing forearm trainers include a connecting tube and a rope wound around the middle of the connecting tube, with a weight attached to the lower end of the rope. By holding both ends of the connecting tube and rotating it to perform a rope-winding motion, the weight is lifted. Repeated training in this manner can fully activate the forearm muscle groups and increase strength.

[0004] Because the connecting tube length is fixed, the handle length cannot be adjusted, failing to meet the fitness needs of different groups. Only various models of forearm trainers with different handle lengths can be manufactured, resulting in high manufacturing and operating costs and low versatility. Utility Model Content

[0005] The purpose of this invention is to provide a forearm trainer that allows for adjustable hand spacing.

[0006] The technical solution of this utility model is: a forearm trainer, including a connecting tube, a tape wound in the middle of the connecting tube, and a handle tube detachably fitted at both ends of the connecting tube. The connecting tube is provided with a plurality of adjustment holes spaced apart along the axial direction. The handle tube is through at both ends and has an insertion hole at one end. The insertion hole is aligned with the adjustment hole and fixed by a positioning pin.

[0007] Preferably, the handle tube includes a second tube body and an anti-slip sleeve fitted onto the outside of the second tube body. Multiple anti-slip sleeves are spaced apart along the axial direction of the second tube body. The second tube body is fitted onto the connecting tube, and the insertion hole is located on the second tube body.

[0008] Preferably, the anti-slip sleeve is a rubber sleeve.

[0009] Preferably, a connecting post is fitted into the middle of the connecting tube, and the tape is wound onto the connecting post.

[0010] Preferably, the connecting column includes a connecting plate, a sleeve, and a screw. Two connecting plates are spaced apart on the connecting tube. Multiple through holes are arranged circumferentially on the connecting plate. The sleeve is located between the two connecting plates and is arranged in a one-to-one correspondence with the through holes. The screw is installed at the through hole and is connected to the sleeve. The tape is wound onto the cylinder surrounded by the multiple sleeves.

[0011] Preferably, the connecting plate is a circular ring plate, the inner hole of which is adapted to the connecting pipe.

[0012] Preferably, a hanging ring is connected to the end of the tape away from the connecting tube.

[0013] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0014] I. This utility model features detachable handle tubes at both ends of the connecting tube, enabling adjustable hand spacing, i.e., adjustable handle length, to suit the fitness needs of different groups, reducing the number of forearm trainer models and improving versatility.

[0015] Second, the connecting tube is equipped with multiple adjustment holes, and the handle tube is adapted to the corresponding adjustment holes. On the one hand, this increases the adjustable range, and on the other hand, it makes adjustment and fixing convenient and quick.

[0016] Third, the outside of the handle tube is fitted with an anti-slip sleeve with intervals to prevent slipping while increasing the difficulty of training;

[0017] Fourth, the through holes at corresponding positions on the two connecting plates are connected to the same sleeve by screws, which not only makes installation convenient, but also makes the structure of the connection as a whole more resilient and stable. Attached Figure Description

[0022] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0023] like Figure 1, Figure 2 As shown, the forearm trainer provided in this embodiment includes a connecting tube 1, a handle tube 2, a connecting column 3, a positioning pin 4, a winding belt 5, and a hanging ring 6.

[0024] like Figure 3 As shown, the connecting pipe 1 includes a first pipe body 11, an end plate 12, and adjustment holes 13. The first pipe body 11 is a circular pipe with both ends open, and its two ends are covered by the end plate 12. A connecting post 3 is installed in the middle of the first pipe body 11, and multiple adjustment holes 13 are arranged axially at both ends of the first pipe body 11. The multiple adjustment holes 13 can be arranged at equal or unequal intervals to increase the length adjustment range.

[0025] The handle tube 2 is open at both ends and inserted into the first tube body 11. An insertion hole 23 is formed on the tube wall at the front end of the handle tube 2 in the insertion direction. The insertion hole 23 is aligned with the adjustment hole 13 therein and fixed by a positioning pin 4. The handle tube 2 includes a second tube body 21 and an anti-slip sleeve 22 fitted onto the outside of the second tube body 21. Multiple anti-slip sleeves 22 are spaced apart along the axial direction of the second tube body 21. The anti-slip sleeve 22 is a rubber sleeve. The second tube body 21 is fitted onto the connecting tube 1. One end of the positioning pin 4 has a T-shaped head that engages with one side wall of the handle tube 2 forming the insertion hole 23. The other end of the positioning pin 4 can have a cotter pin or a compressible ball that engages with the other side wall of the handle tube 2 forming the insertion hole 23. The positioning pin 4 connects the handle tube 2 and the connecting tube 1 as a single unit, transmitting torque. Alternatively, based on user feedback, a portion of anti-slip pads (such as axially spaced pads) can be installed on the inner surface of the handle tube 2, with the same material as the anti-slip sleeve 22, so that the anti-slip pads fit snugly against the outer surface of the connecting tube 1, thus better transmitting torque.

[0026] like Figure 2 , Figure 3 As shown, the connecting post 3 includes a connecting plate 31, a sleeve 32, and a screw 33. Two connecting plates 31 are spaced apart on the connecting pipe 1. Multiple through holes are arranged circumferentially on the connecting plate 31. The sleeve 32 is located between the two connecting plates 31 and corresponds to each of the through holes. The screw 33 is installed at each through hole and connects to the sleeve 32. Both ends of the sleeve 32 have internal threaded holes, which are respectively connected to the screw 33.

[0027] After one end of the winding tape 5 is fixed to a sleeve 32, the winding tape 5 is then wound around a cylinder enclosed by multiple sleeves 32. The other end of the winding tape 5 is connected to a hanging ring 6. In use, the hanging ring 6 is connected to a counterweight of suitable weight, and the length of the handle tube 2 is adjusted to a suitable position. Holding the handle tube 2 and rotating it transmits torque to the connecting tube 1, causing the winding tape 5 to wind up and the counterweight to rise. Through this process, forearm strength is trained. The specific training process of the forearm trainer provided by this utility model is the same as that of existing ones, and will not be described again here.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
