Description

Technical Field

[0001] The utility model relates to a massage device, in particular to a belt-type massage ball. Background Art

[0002] As people pay more attention to health, various types of fitness and health care equipment are increasing. Among them, massage balls are widely used because of their small size and easy to carry, especially massage balls for back massage. The existing peanut-shaped massage balls use two symmetrical spheres, such as patent number 202121497125.1, which can be placed on the ground or connected with drawstrings. The human body lies on the massage ball or pulls the drawstring to achieve local massage of the human body. However, when a single massage ball structure is used, the massage points and surfaces are relatively small, and larger movements are required to complete the massage of more points and surfaces. Moreover, when a human body lies on a single massage ball, the support points and surfaces are subjected to greater force, which can easily cause single-point support damage on the back, posing a safety hazard in use. Summary of the invention

[0005] Furthermore, the shape of the connecting hole is adapted to the connecting belt.

[0006] Furthermore, the connecting belt is a nylon belt, a rubber belt or a leather belt.

[0007] Furthermore, the end of the connecting belt extends out of the last through hole to form a buckle section, and a male buckle head or a female buckle head is arranged outward on the buckle section, and a female buckle head or a male buckle head corresponding to the above-mentioned male buckle head or female buckle head is arranged on the connecting belt on the inner side of the last through hole.

[0008] Furthermore, the roller shaft is also connected with a transition sleeve located between the two massage balls, and the transition sleeve and the two massage balls on both sides form a spherical arc transition fit; or the roller shaft is composed of left and right roller shaft sections axially spliced ​​through a transition sleeve, and the transition sleeve and the two massage balls on both sides form a spherical arc transition fit.

[0009] Furthermore, a raised plug-in shaft section is arranged in the middle of the roller shaft, and two plug-in bayonet structures are arranged on the plug-in shaft section facing back to back on both sides. The two half-sections of the transition sleeve are respectively inserted into the roller shaft and the plug-in bayonet structures are assembled into a transition sleeve overall structure with a spherical arc transition fit between the two massage balls.

[0010] Furthermore, roller shaft screw holes are arranged at the centers of both ends of the roller shaft, and locking holes of the side connecting seats are penetrated by locking screws and screwed to the roller shaft screw holes.

[0011] Furthermore, anti-rotation clamps are provided at both ends of the roller shaft, and the anti-rotation clamps are plugged into anti-rotation sockets on the inner side of the side connecting seat.

[0012] Furthermore, a sleeve is arranged between the roller and the massage ball, and the sleeve abuts against the inner side of the side connecting seat outwardly and abuts against the transition sleeve inwardly. The sleeve is an integral whole, or the sleeve is an inner sleeve and an outer sleeve respectively plugged into the inside and outside of the massage ball, and the inner and outer sides of the inner and outer sleeves are connected with sleeve flanges, and the sleeve flanges are positioned and abutted against the inner and outer sides of the massage ball.

[0013] Furthermore, massage protrusions are arranged on the surface of the massage ball, and the massage protrusions are convex dots, pattern protrusions or flower-shaped protrusions.

[0014] The beneficial effects of the utility model are:

[0015] 1. Multiple massage ball groups are arranged in sequence front and back, and connected into a whole through a side connecting seat and a connecting belt. When in use, they can be adjusted according to the required number of groups to meet the requirements of multi-point and large-area massage.

[0016] 2. It can be placed on the ground to support the shoulders, neck, back, waist, legs, arms and feet of the human body. The massage ball group rolls as a whole as the human body moves, or you can lie down or step on it directly to achieve support massage. The performance is stable and safe.

[0017] 3. The flexible structure connected in series with connecting belts is adopted. The two ends of the overall structure can be held by hand to pull and press the neck, shoulders, back, arms, legs and other parts of the human body for massage. It has more functions and stronger applicability.

[0018] 4. The side connecting seat is installed on the outside of the massage ball of the massage ball group. The locking screw is inserted through the locking hole on the side connecting seat to lock the connecting belt and the roller shaft, which helps to ensure the firmness and stability of the overall structure assembly, while avoiding the sliding of the connecting belt, ensuring the stable positioning and connection of multiple groups of massage balls.

[0019] 5. A buckle head is provided at the buckle section at the outermost end of the connecting belt, which can be folded back and buckled to the mouth of the connecting belt after passing through the outermost group of massage balls, thereby avoiding the pulling and loosening of the locking screw at the outermost end of the connecting belt and improving the overall assembly performance.

[0020] 6. A transition sleeve is provided between the two massage balls of the massage ball set, which not only improves the overall appearance but also ensures the effective grasping and taking of the massage ball set, making it easier to operate massage and fitness operations.

[0021] 7. The roller shaft adopts a plug-in bayonet structure of the plug-in shaft section to connect the two halves of the transition sleeve, so as to assemble an integral transition sleeve structure. The plug-in bayonet structure can be made into a circle structure, which is convenient for injection molding production and positioning plug-in assembly, and can ensure the overall beauty of the structure; when the roller shaft, the side connecting seat, and the transition sleeve overall structure are connected as one, the rotation of the roller shaft and the transition sleeve overall structure is effectively prevented; and the massage ball is connected to the roller shaft through the inner and outer shaft sleeves, which can provide better support and rolling support to achieve a similar bearing effect, ensuring the stable rotation of the massage ball.
