Description

Technical Field

[0001] This utility model relates to the field of massagers, specifically to a radial array type point-and-roll massage stick. Background Technology

[0002] In modern society, people face increasing work and life pressures, making physical fatigue and muscle tension common health problems. To alleviate these discomforts, massage, as an effective relaxation and soothing method, has gradually gained widespread attention and popularity. Massage devices, as important tools to assist massage, are also experiencing increasing market demand. Among them, massage sticks, with their portability, ease of use, and relatively low price, have been widely used in homes and offices.

[0003] However, traditional massage sticks have many limitations in design and function. First, in terms of massage methods, traditional massage sticks usually rely on manual operation or simple vibration modes. This single massage method cannot simulate the rich and diverse techniques in human massage, such as pushing, pressing, and kneading, resulting in limited massage effects and failing to meet users' needs for deep relaxation and soothing. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a radial array type point-and-roll massage stick: A radial array type touch-rolling massage stick includes a main body, which comprises a radial pushing mechanism, a cylindrical shell, and an elastic outer sleeve. The radial pushing mechanism is disposed in an installation cavity provided within the cylindrical shell. The radial pushing mechanism includes a battery, a control switch, a drive motor, a central shaft, and multiple radial push rods. The battery, control switch, and drive motor are electrically connected in sequence. The control switch is used to control the start and stop of the drive motor. The drive motor is driven and connected to the central shaft. The central shaft is provided with multiple axially distributed eccentric shaft portions. The eccentric shaft portions are movably sleeved with radial push rods. The radial push rods pass through radial holes provided in the cylindrical shell and are snapped into locking grooves provided in the elastic outer sleeve. When the drive motor drives the eccentric shaft portions to rotate eccentrically, the radial push rods perform intermittent radial protrusion movements relative to the surface of the elastic outer sleeve.

[0005] Preferably, the cylindrical shell is composed of two corresponding semi-cylindrical shells that are interlocked with each other, and the elastic outer sleeve covers the cylindrical shell and is used to fix the relative position of the semi-cylindrical shells.

[0006] Preferably, each of the eccentric shaft portions is provided with two adjacent and mutually perpendicular radial push rods, and the four radial push rods of adjacent eccentric shaft portions are arranged in a mutually perpendicular circumferential array.

[0007] Preferably, the battery and control switch are respectively positioned above and below the drive motor. The control switch includes a circuit board and a button. The cylindrical housing has an opening corresponding to the button, and the elastic outer sleeve has an arc-shaped inner groove corresponding to the button. The user starts and stops the button by pressing the bottom surface of the arc-shaped inner groove. If the area of ​​the elastic outer sleeve corresponding to the button has an outward convex structure, accidental touches can easily occur during the rolling of the massage stick, causing the button to be repeatedly pressed to start and stop. Therefore, this invention specifically adopts an arc-shaped inner groove structure for the corresponding area of ​​the elastic outer sleeve, which can effectively avoid the problem of accidental button touches.

[0008] Preferably, one end of the central shaft is connected to a drive motor, and the shaft head at the other end of the central shaft and the journal in the middle are movably connected to the bearing seat in the cylindrical housing.

[0009] Preferably, adjacent journals or eccentric shaft portions are mutually limited and separated by a collar, the diameter of which is larger than that of the journal and the eccentric shaft portion, and the collar defines the axial displacement position of the radial push rod relative to the central shaft.

[0010] Preferably, the radial push rod includes an annular hook portion, a rod body portion, and a top flange that are integrally and sequentially fixedly connected. The annular hook portion is movably sleeved on the eccentric shaft portion. The outer surface of the top flange has an arc surface structure. The top flange is radially protruding relative to the rod body portion. The top flange is locked in a locking groove on the inner surface of the elastic sleeve. The outer surface of the elastic sleeve is provided with an elastic protrusion corresponding to the locking groove.

[0011] Preferably, it also includes two handles respectively hinged to both ends of the main rod body. The handles include an integral hinge end and a grip portion. The hinge end is disposed inside the cylindrical shell, and the grip portion is located outside the cylindrical shell.

[0012] Preferably, the hinge end includes a connecting part and an annular limiting groove. The connecting part is movably fitted with a movable bearing provided in the cylindrical housing. The annular limiting groove is located near the grip part. The annular limiting groove and an annular protrusion provided in the cylindrical housing form a snap-fit ​​limiting engagement, thereby limiting the axial displacement of the handle relative to the cylindrical housing.

[0013] Preferably, the two ends of the grip are provided with radially protruding limiting flanges, one of which (21) cooperates with the end face of the cylindrical shell to clamp the edge of the elastic outer sleeve.

[0014] Beneficial effects: (1) By controlling the intermittent lifting motion of the radial push rod through the radial pushing mechanism, it can simulate complex techniques such as pushing, pressing, and kneading in manual massage, providing users with a more realistic and comfortable massage experience. This diverse massage method can penetrate deep into muscle tissue and effectively relieve muscle tension and fatigue. (2) The design of the rolling massage stick allows the main body to roll repeatedly on the surface of human skin, thereby expanding the massage area. Compared with traditional massage sticks, it can cover a wider area, improve massage efficiency, and allow users to obtain a more comprehensive relaxation effect in a short time.

[0023] The following is in conjunction with the appendix Figures 1-7 The present invention will be further described with reference to Example 1.

[0024] Example 1: A radial array type tapping and rolling massage stick, comprising a main body and two handles respectively hinged to both ends of the main body. The main body includes a radial pushing mechanism, a cylindrical shell, and an elastic outer sleeve. The radial pushing mechanism is disposed in an installation cavity within the cylindrical shell, which is fitted inside the elastic outer sleeve. The cylindrical shell is formed by two corresponding semi-cylindrical shells interlocking with each other. The elastic outer sleeve covers the cylindrical shell and is used to fix the relative position of the semi-cylindrical shells. This product can either use the handles to roll the main body, or apply a corresponding force directly to the surface of the main body, using a rolling pin-like motion to make the massage stick roll relative to the human skin surface.

[0025] The radial push-press mechanism includes a battery, a control switch, a drive motor, a central shaft, and multiple radial push rods. The battery, control switch, and drive motor are electrically connected in sequence. The control switch controls the start and stop of the drive motor. The drive motor is driven by the central shaft, which has multiple axially distributed eccentric shaft portions. Each eccentric shaft portion is movably fitted with a radial push rod. The radial push rod passes through a radial hole in the cylindrical housing and is snapped into a locking groove in the elastic outer sleeve. When the drive motor drives the eccentric shaft portion to rotate eccentrically, the radial push rod performs intermittent radial protrusion movement relative to the surface of the elastic outer sleeve. Each eccentric shaft portion has two adjacent and mutually perpendicular radial push rods, and the four radial push rods of adjacent eccentric shaft portions are arranged in a mutually perpendicular circumferential array. The battery and control switch are respectively located above and below the drive motor. The control switch includes a circuit board and a button. The cylindrical housing has an opening corresponding to the button, and the elastic outer sleeve has an arc-shaped inner groove corresponding to the button. The user starts and stops the button by pressing the bottom surface of the arc-shaped inner groove. If the area corresponding to the elastic sleeve of the button has an outward protruding structure, accidental activation can easily occur during the rolling of the massage stick, causing the button to be repeatedly pressed to start and stop. Therefore, this invention specifically adopts an arc-shaped inner groove structure for the corresponding area of ​​the elastic sleeve, which can effectively avoid the problem of accidental button activation. One end of the central shaft is connected to a drive motor, and the shaft head and journal at the other end of the central shaft are movably connected to the bearing seat in the cylindrical housing. Adjacent journals or eccentric shaft portions are mutually limited and separated by a collar. The diameter of the collar is larger than that of the journal and the eccentric shaft portion, and the collar limits the axial displacement position of the radial push rod relative to the central shaft.

[0026] The radial push rod includes an annular hook, a rod body, and a top flange that are integrally and sequentially fixedly connected. The annular hook is movably sleeved on the eccentric shaft. The outer surface of the top flange has an arc-shaped structure. The top flange is radially protruding relative to the rod body. The top flange is locked in a locking groove on the inner surface of the elastic sleeve. The outer surface of the elastic sleeve is provided with an elastic protrusion corresponding to the locking groove.

[0027] The handle includes an integral hinge end and a grip portion. The hinge end is located inside a cylindrical housing, while the grip portion is located outside the cylindrical housing. The hinge end includes a connecting portion and an annular limiting groove. The connecting portion and a movable bearing inside the cylindrical housing form a movable sleeve fit. The annular limiting groove, located near the grip portion, and a ring-shaped protrusion inside the cylindrical housing form a snap-fit ​​limiting engagement. Both ends of the grip portion have radially protruding limiting flanges, one of which forms a clamping and fixing structure with the cylindrical housing to create an elastic outer sleeve. Anti-slip protrusions are evenly distributed on the surface of the grip portion.

[0028] In practical applications, users can grasp the handle and press the main body against the skin of the back. Under the action of the radial pushing mechanism, the elastic outer sleeve will intermittently lift up to massage the fixed acupoints and achieve the corresponding massage effect. Alternatively, users can use a rolling method to roll the entire main body back and forth relative to the back of the user, and achieve rolling massage through the protrusions.

[0029] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
