Description

Technical Field

[0001] This utility model relates to the field of exercise assistive equipment technology, specifically a multi-functional integrated palm exercise machine. Background Technology

[0002] Iron Palm, a classic hard-skill training method in traditional Chinese martial arts, primarily involves repeatedly striking hard objects such as iron sandbags, sandbags, or stones to enhance the hardness, strength, and resistance to blows in the palm. Based on Wolf's Law, its core training principle lies in increasing bone density in the hand through long-term mechanical stimulation, thereby improving striking and defensive capabilities in actual combat.

[0003] However, existing Iron Palm training methods have the following significant drawbacks:

[0004] 1. Traditional methods rely on practitioners to actively strike hard objects, which is a passive adaptive training method. It requires long-term and repeated practice to see results, which is time-consuming and makes it difficult to quickly improve the hardness of the palm and its impact resistance.

[0005] 2. Practitioners need to concentrate highly to adjust the striking force. Excessive force can easily lead to hand injuries (such as bone fractures or soft tissue contusions), while insufficient force will not effectively stimulate the hand tissues and affect the training effect.

[0006] Therefore, there is an urgent need for an Iron Palm training device that can optimize the training process, improve efficiency, and reduce the risk of injury, in order to overcome the limitations of traditional training methods. Summary of the Invention

[0007] To address the technical problems in the background art, this utility model discloses a multi-functional integrated palm-power machine.

[0008] This utility model provides a multi-functional hand massager, including a base, on which are provided:

[0009] The striking plate is hinged to the base, and there is a gap between the hinge point and the center of gravity of the striking plate.

[0010] Gear motor;

[0011] The drive rod is perpendicular to the drive shaft of the geared motor. One end of the drive rod is fixedly connected to the drive end of the geared motor, and the other end makes a circular motion to drive one end of the striking plate to descend or detach from the striking plate. When the drive rod detaches from the striking plate, the other end of the striking plate moves freely downward under the action of gravity and strikes the hand.

[0012] Furthermore, a drive bearing is installed at the other end of the drive rod; when the drive rod drives the striking plate, the outer ring of the drive bearing contacts the striking plate.

[0013] Furthermore, a rubber pad is provided at the contact point between the striking plate and the drive rod.

[0014] Furthermore, a height-adjustable support plate is installed on the base; when the other end of the striking plate falls, it contacts the upper surface of the support plate; the hand is placed on the upper end of the support plate.

[0015] Furthermore, the base is provided with a vertically arranged rack; a gear meshes on the rack; the gear is mounted on a sleeve that engages with the rack via a movable connection; a movable drive block is mounted on the sleeve for driving the gear to rotate; a support plate is fixed to one side of the sleeve; and a pawl for engaging the gear is also provided on the sleeve.

[0016] Furthermore, the gear is rotatably connected to the sleeve via the first coupling; the drive block is installed in the U-shaped shift fork with its open end movably connected to the first coupling, and is rotatably connected via the second coupling; a first torsion spring is sleeved on the second coupling; the elastic force of the first torsion spring causes pressure to be generated between the drive block and the bottom of the gear tooth groove.

[0017] Furthermore, the pawl extends out of the force-bearing part; when the shift fork rotates to a certain angle, it drives the force-bearing part to rotate, causing the pawl to disengage from the gear.

[0018] Furthermore, the opening and closing end of the shift fork is also connected to a handle.

[0019] Furthermore, the striking part of the striking plate is welded with striking blocks.

[0020] Furthermore, the base is also equipped with a housing that covers the geared motor and drive bearing; a horizontally arranged connecting frame is installed on the housing; a fixed roller and a floating roller are arranged radially side by side at intervals on the connecting frame; the fixed roller is fixed in position; the side of the floating roller facing away from the fixed roller is elastically connected to the connecting frame by a spring; an adjusting bolt is also threadedly connected to the connecting frame; the threaded end of the adjusting bolt abuts against the floating roller.

[0021] The beneficial effects of this utility model are:

[0022] 1. By using a speed-reducing motor to drive the striking board to automatically strike, the traditional passive striking training is transformed into an active force application mode. The gravitational potential energy of the striking board is converted into impact force, which significantly improves the bone density of the hands.

[0023] 2. The design adopts a separate drive rod and striking plate. When the drive rod is separated from the striking plate, the striking plate falls freely with constant gravitational acceleration, ensuring that the force of each strike is uniform and controllable, which can both reach the effective stimulation threshold and avoid hand damage caused by sudden changes in force.

[0024] 3. By adjusting the speed of the geared motor, the striking frequency can be changed to meet the strength requirements of different training stages.

[0025] 4. Training can be completed simply by placing your hand on the striking position of the hitting board. No continuous attention is required, which effectively avoids movement distortion and accidental injury caused by fatigue in traditional training. Moreover, the free hand can be used for other operations during training, improving the utilization of time. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0039] Example 1: As Figure 1 and Figure 2 As shown, this utility model discloses a multi-functional hand massager, including a base 1. A vertically arranged mounting plate 22, parallel to the base's length, is mounted on the upper surface of the base 1. Parallel and spaced support plates 23 are arranged on one side of the mounting plate 22. Both the mounting plate 22 and the support plates 23 are fixed to the base 1 by welding. One end of the mounting plate 22 extends to one end of the base 1 and is vertically bent to improve its structural stability. The lower end of the support plate 23 is vertically bent into an L-shape, and its bent portion is welded to the base 1, also to improve the stability of the support plate 23.

[0040] A geared motor 3 is mounted on one side of the mounting plate 22. The drive end of the geared motor 3 is connected to a horizontally arranged drive shaft, which passes through the mounting plate 22 and extends to the other side of the mounting plate 22. One end of a drive rod 4, perpendicular to the drive shaft, is engaged with the end of the drive shaft via a profile connection; the other end of the drive rod 4 is fitted with a rotatably connected drive bearing 5. Thus, when the geared motor 3 is started, it can drive the drive rod 4 to perform circular motion.

[0041] A horizontally arranged shaft is also connected between the mounting plate 22 and the support plate 23. Symmetrically arranged protruding plates extend from the lower side of the flat striking plate 2, and these protruding plates are fitted onto the shaft, enabling the striking plate 2 to be rotatably connected to the base 1. A gap is provided between the protruding plates and the center of gravity of the striking plate 2, and the protruding plates are located near one end of the striking plate 2, so that the striking plate 2 forms two parts, one long and one short, on both sides of the protruding plates. The longer part automatically droops under the weight of the striking plate 2, while the shorter part tilts upwards. The shorter part extends towards the drive bearing 5. When the reduction motor 3 starts, the drive bearing 5 performs two cyclical actions: first, it applies downward pressure to the shorter part of the striking plate 2, causing the shorter part to move downwards and the longer part to move upwards; second, the drive bearing 5 disengages from the striking plate 2, and under the weight of gravity, the longer part of the striking plate 2 moves downwards and the shorter part moves upwards. As the longer part moves downwards under the influence of gravity, it generates a downward impact force. Placing your hand directly below the striking part of the striking plate 2 allows you to be struck by the plate, achieving the purpose of exercise. The drive bearing 5 is included to rotatably connect with the striking plate 2, reducing wear.

[0042] To increase the impact force of the slapping plate 2 and improve the training effect, a striking block 19 is welded to the slapping part of the slapping plate 2 to increase the weight of the slapping part of the slapping plate 2, thereby increasing the dynamic potential energy of the slapping part and increasing the impact force on the hand.

[0043] The above setup offers the following advantages: 1. By using a reduction motor 3 to drive the striking plate 2 for automatic hammering, traditional passive striking training is transformed into an active force application mode. The gravitational potential energy of the striking plate 2 is converted into impact force, significantly improving bone density in the hands. 2. The separate design of the drive rod 4 and the striking plate 2 ensures that when the drive rod 4 detaches from the striking plate 2, the striking plate 2 falls freely with constant gravitational acceleration, guaranteeing uniform and controllable striking force for each strike. This achieves the effective stimulation threshold while avoiding hand injuries caused by sudden changes in force. 3. The striking frequency can be changed by adjusting the speed of the reduction motor 3 to meet the strength requirements of different training stages. 4. Training can be completed simply by placing the hand on the striking position of the striking plate 2, without the need for continuous attention control. This effectively avoids movement distortion and accidental injuries caused by fatigue in traditional training. Furthermore, the freed hand can be used for other operations during training, improving time utilization.

[0044] Because the hard contact between the drive bearing 5 and the striking plate 2 generates a lot of noise, a rubber pad 6 is also provided at the upper end of the shorter part of the striking plate 2, and the drive bearing 5 contacts the rubber pad 6 to reduce noise.

[0045] A vertically arranged rack 8 is provided at one end of the base 1, which is located at the striking part of the striking plate 2, and its lower end is fixed by welding. The teeth of the rack 8 face the outside of the base 1.

[0046] A sleeve 10 is fitted onto the rack 8. A slot is formed on one side of the sleeve 10, and the opening of the slot is rotatably connected to a gear 9 via a first coupling 13, meshing with the rack 8. A horizontally arranged support plate 7 is provided on the other side of the sleeve 10, with the hand placed on top of the support plate 7. The support plate 7 is located below the striking plate 2 and directly opposite the striking part of the striking plate 2. By driving the gear 9 to rotate, the height of the sleeve 10 and the height of the support plate 7 can be adjusted. This allows adjustment of the distance between the hand and the striking part, and the downward movement distance of the striking part, thereby adjusting the impact force of the striking part to achieve a gradual hand exercise effect.

[0047] The specific structure for driving gear 9 to rotate is as follows: Figure 3 As shown, a U-shaped shift fork 14 with its open end rotatably connected to the first connecting shaft 13 is also provided. A second connecting shaft 15 is connected to the side wall of the shift fork 14 near its bottom, and a drive block 11 is sleeved on the second connecting shaft 15. One end of the drive block 11 has teeth that engage with the tooth groove of the gear 9. A slot is formed at the center of the drive block 11, exposing the second connecting shaft 15 at this location. A first torsion spring 16 is sleeved on the second connecting shaft 15 at this location, creating pressure between the drive block 11 and the tooth groove of the gear 9. When the shift fork 14 rotates, the drive block 11 drives the gear 9 to rotate. A handle 18 is also connected to the outer side of the bottom of the shift fork 14, which not only facilitates operation but also saves effort.

[0048] Meanwhile, to improve the positional stability of the support plate 7 after adjustment, such as Figure 4 As shown, the sleeve 10 is also equipped with a pawl 12 that engages with the gear 9, allowing the gear 9 to rotate only in one direction. In this embodiment, the pawl 12 is positioned such that when the gear 9 rotates upward, the gear 9 is not obstructed by the pawl 12; when the gear 9 rotates downward, the pawl 12 is always engaged in the tooth groove of the gear 9, creating resistance. Thus, when a hand is placed on the support plate 7, under the influence of gravity and habit, a downward pressure is exerted on the support plate 7. At this time, the resistance of the pawl 12 keeps the support plate 7 stable.

[0049] like Figure 5 and Figure 6 As shown, the pawl 12 is movably connected to the sleeve 10 via a connecting rod. A second torsion spring 21 is installed on this connecting rod, which is used not only to improve the stability of the pawl 12 engaging the gear 9, but also to reset the pawl 12.

[0050] The pawl 12 also extends a force-bearing part 17 towards the handle 18. When the shift fork 14 rotates a certain angle towards the pawl 12, it will drive the pawl 12 to rotate and disengage from the gear 9, so that the gear 9 rotates without resistance, and the sleeve 10 can engage with or disengage from the rack 8 without resistance.

[0051] The pawl 12 also provides another training effect: by rotating the sleeve 10 180° to engage the rack 8, the upward movement of the support plate 7 is resisted by the pawl 12. By placing the hand between the base 1 and the support plate 7 and driving the support plate 7 downward to the position where pressure is applied to the hand, the hand can be subjected to constant pressure for a prolonged period of time.

[0052] In this embodiment, a storage battery 20 is also installed on the base 1 to power the geared motor 3, so that the device can be moved to any suitable position for exercise without being limited by a fixed power source.

[0053] Example 2: The difference from Example 1 is as follows: Figure 7-10 As shown, a cover 24 is also provided on the base 1. Figure 9 For reference, the cover 24 is flush with the right, top, and bottom ends of the base 1, and the left end of the cover 24 extends to the mounting plate 22 to provide waterproofing and dustproofing. The left and top sides of the cover 24 are provided with clearance grooves 30, the length and width of which are configured so that the striking plate 2 will not collide with the cover 24 when it rotates.

[0054] A horizontally arranged connecting frame 25 is fixedly connected to the right side of the top of the cover 24 by welding. The connecting frame 25 consists of two symmetrically arranged horizontal bars and a vertical bar connecting the right end of the horizontal bars. Both the horizontal bars and the vertical bar are square tubes. The horizontal bars are connected to the front and rear sides of the cover 24, and their upper ends are flush with the top of the cover 24.

[0055] The fixed roller 26 is located between two crossbars, with its shaft passing through the crossbars and extending outwards. The end of this shaft is a screw, which is locked in place by a threaded nut to keep the fixed roller 26 in a fixed position.

[0056] The crossbar has a groove 31 that runs through the inner and outer sides along its length. The rotating shafts at both ends of the floating roller 27 extend outward from the groove 31. Both ends of the rotating shaft are also screws, and the installation is limited by the threaded nuts, so that the floating roller 27 can move radially, closer to or away from the fixed roller 26.

[0057] The crossbar is equipped with a fixed block 32 and a floating block 33 that are clearance-fitted with its inner wall, allowing it to slide within the crossbar; these blocks also limit their movement, preventing rotation. The fixed block 32 has a through hole through which the rotating shafts at both ends of the floating roller 27 pass. A protruding limiting post is located at the right end of the fixed block 32. The floating block 33 is located to the right of the fixed block 32, and its left end also has a protruding limiting post. A spring 28 is installed inside the crossbar, with a limiting post fitted at each end to improve the stability of its installation position. The outer wall of the spring 28 is clearance-fitted with the inner wall of the crossbar to improve its expansion and contraction stability and prevent bending.

[0058] The right end of the crossbar is sealed with a threaded block 34. The threaded block 34 has a threaded hole. The adjusting bolt 29 is threadedly connected to the threaded hole, and its threaded end abuts against the floating block 33 to adjust the compression amplitude of the spring 28, thereby adjusting the elastic force of the spring 28.

[0059] The fixed roller 26 and the floating roller 27 are used for hand rolling exercises. The specific operation is as follows: with the palms together and fingers pointing down, perform the following two actions repeatedly: First, insert the palm downward between the fixed roller 26 and the floating roller 27. The floating roller 27 will move away from the fixed roller 26 under the squeezing action of the palm. Under the action and reaction forces, the fixed roller 26 and the floating roller 27 apply pressure to both sides of the palm for exercise. Second, move the palm upward to get away from the fixed roller 26 and the floating roller 27.

[0060] The floating roller 27 abuts against the left end of the slide groove 31 under the elastic force of the spring 28. At this time, there is a gap between the fixed roller 26 and the floating roller 27 to facilitate the insertion of the palm between the fixed roller 26 and the floating roller 27.

[0061] By adjusting the elasticity of the spring 28, the pressure of the fixed roller 26 and the floating roller 27 on the palm can be adjusted for gradual exercise.

[0062] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
