Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, and in particular relates to a hugging and pulling fitness device which can assist in exercising back muscles. Background Art

[0002] A pull-up exercise machine is a device specifically designed for back muscle training. It usually includes a handle or grip that the user can pull or push to exercise the back muscles, increase back strength and improve rounded shoulders and hunchback posture.

[0003] Existing back muscle training methods typically involve gripping a barbell with both hands and pulling it closer to the torso. However, due to the hot summer weather, hands sweat a lot, making them prone to slipping, leading to frequent injuries. Furthermore, the arms are largely used for support, failing to effectively stimulate the target back muscles. Therefore, we propose a pull-up fitness device that can assist in back muscle training. Utility Model Content

[0004] The purpose of the present invention is to provide a pull-up fitness device that can assist in training back muscles, so as to solve the problems of slipping, safety and leverage when using ordinary barbells to train back muscles in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a pulling and hugging fitness device that can assist in back muscle training, comprising a sleeve, a triangular support frame is provided at the bottom of the sleeve, a fixing rod is provided at the bottom end of the triangular support frame, a non-slip sleeve is provided on the surface of the fixing rod, a connecting tube is provided on the surface of the sleeve, a screw rod is provided on the inner side of the connecting tube, a spring is provided inside the sleeve, a splint is provided at the end of the spring, and a hexagonal hole is provided on the end surface of the screw rod.

[0006] Preferably, triangular support frames are respectively installed at both ends of the bottom of the sleeve, and the bottom end surface of the triangular support frame is fixedly connected to the upper end surfaces of the fixing rod.

[0007] Preferably, a non-slip sleeve is fixedly mounted on the middle portion of the surface of the fixing rod, and connecting tubes are fixedly mounted on both sides of the surface of the sleeve, and the interior of the connecting tube is communicated with the interior of the sleeve.

[0008] Preferably, the inner thread of the connecting tube is rotatably connected to a screw rod, and the inner surface of the sleeve is fixedly mounted with a spring.

[0009] Preferably, a clamping plate is fixedly mounted on the end of the spring, and the spring and the clamping plate are evenly mounted around the center of the circle inside the sleeve.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The provided sleeve makes it easy to insert the barbell rod into the interior, and the screw rod is rotated until its end is in close contact with the surface of the barbell rod inside the sleeve, thereby improving the stability of the connection between the barbell rod and the sleeve. The user can hold the anti-slip sleeve and drive the barbell rod closer to the torso for exercise, accurately stimulating the target back muscles and avoiding slipping, safety and leverage problems.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The utility model provides a technical solution: a hugging and pulling fitness device that can assist in exercising the back muscles, comprising a sleeve 1, a triangular support frame 2 is provided at the bottom of the sleeve 1, a fixing rod 3 is provided at the bottom end of the triangular support frame 2, a non-slip sleeve 4 is provided on the surface of the fixing rod 3, a connecting tube 5 is provided on the surface of the sleeve 1, a screw rod 6 is provided on the inner side of the connecting tube 5, a spring 7 is provided inside the sleeve 1, a splint 8 is provided at the end of the spring 7, and a hexagonal hole 9 is provided on the end surface of the screw rod 6.

[0018] Specifically, triangular support frames 2 are respectively installed at both ends of the bottom of the sleeve 1, the bottom end surface of the triangular support frame 2 is fixedly connected to the upper end surfaces of the fixed rod 3, the middle part of the surface of the fixed rod 3 is fixedly sleeved with an anti-slip sleeve 4, and connecting tubes 5 are fixedly installed on both sides of the surface of the sleeve 1. The interior of the connecting tube 5 is communicated with the interior of the sleeve 1, and the inner side of the connecting tube 5 is rotatably connected to a screw rod 6. A spring 7 is fixedly installed on the inner surface of the sleeve 1, and a splint 8 is fixedly installed on the end of the spring 7. The spring 7 and the splint 8 are evenly installed around the center of the circle inside the sleeve 1.

[0019] In this embodiment, when using a barbell to exercise the back muscles, the sleeve 1 is first inserted into the surface of the barbell lever. Through the provided spring 7 and splint 8, the splint 8 and the spring 7 can be compressed to different degrees according to the thickness of the barbell rod. The spring 7 can make one side of the splint 8 fit with the surface of the barbell rod, thereby preliminarily improving the stability of the barbell rod inside the sleeve 1. Then, one end of the hexagonal wrench is inserted into the inside of the hexagonal hole 9 to facilitate driving the screw rod 6 to rotate inside the connecting tube 5 until the end of the screw rod 6 is tightly abutted against the surface of the barbell rod inside the sleeve 1, thereby further improving the stability of the connection between the barbell rod and the sleeve 1. The user can hold the anti-slip sleeve 4 and drive the barbell rod to move closer to the torso to accurately stimulate the target back muscles and avoid slipping, safety and leverage problems.
