Description

Technical Field

[0001] The invention belongs to the field of abdominal massage, and in particular relates to an adjustable abdominal massage device. Background Art

[0002] As a traditional Chinese medicine physiotherapy method, abdominal massage has the functions of promoting blood circulation, relieving muscle fatigue, and regulating gastrointestinal function. In recent years, with the improvement of health awareness, it has gradually been combined with modern smart devices, and a variety of abdominal massage devices have been derived. Existing abdominal massage equipment mostly uses mechanical rotation or vibration to press and knead the abdomen through massage balls or rollers to simulate manual massage techniques. This type of equipment is usually driven by a motor to rotate the massage surface, and multiple massage balls are evenly distributed on the massage surface, aiming to relax muscles and improve metabolism through continuous pressure stimulation.

[0003] Although the existing technology has achieved a certain degree of automated massage, its design still has shortcomings. First, the massage balls of the existing devices are usually evenly fixed and distributed on the massage surface. There are generally multiple massage balls on the same motion trajectory. When the massage surface fits the abdomen and rotates, the same abdominal area will be repeatedly compressed due to the periodic contact of the massage balls. However, the distance between two adjacent massage balls on the same motion trajectory is relatively scattered. Compared with the pressing and massaging method of the manual palm, the effective area of ​​the massage ball pressing the same area at a time is limited. For some users with thick abdominal fat, the massage effect is limited and there are great limitations. In addition, the existing abdominal massage device usually adjusts the pressing force of the massage ball and the abdomen through a belt. Since the tightening pressure of the belt is difficult to accurately control, it often happens that after tightening, the working pressure of the massage ball on the abdomen is too large or too small, and it is difficult to cooperate with the massage ball to achieve the appropriate massage intensity for different patients, thereby reducing the quality of massage.

[0035] In specific operation, when the device is placed on the user's abdomen as a whole and fixed by the strap assembly 3, as the pressure increases, the compression spring 1 74 compresses to provide continuous and non-rigid pressure on the installation slide frame 8. At the same time, after the massage ball 428 at each position contacts the user's abdomen, the compression spring 2 425 will be compressed. Under the action of the compression spring 2 425, the massage ball 428 will adaptively fit the user's abdomen according to the height of the area and provide a certain amount of pressure. Then, the two drive motors 91 synchronously drive the corresponding driving gear 92 to rotate and jointly drive the driven gear 93 to rotate, driving the rotating shaft 71 to rotate, so that the connecting disk 72 drives the installation slide frame 8 to rotate, thereby enabling the massage mechanism 4 below to rotate. Providing two drive motors 91 can provide sufficient and more stable driving force for the installation slide frame 8.

[0036] See also Figure 3 , Figure 4 , Figure 5 and Figure 8 A fixing seat 11 is fixedly arranged at the middle position of the upper inner wall of the installation slide frame 8. The fixing seat 11 is a truncated cone structure. Two arc grooves 13 symmetrical to the axis of the fixing seat 11 are opened on the peripheral side wall. Arc-shaped guide rods 12 are fixedly arranged in the two arc grooves 13. The two massage seats 41 are slidably connected to the corresponding guide rods 12 through guide blocks, and the two massage seats 41 can rotate around the fixing seat 11.

[0037] See also Figure 4 , Figure 5 and Figure 8 , the two massage seats 41 rotatably connected to the fixed seat 11 are both provided with sliding holes extending radially along the massage seats 41, the locking assembly 43 includes a limiting column 431 slidably arranged in the sliding hole and having a rectangular structure, four locking grooves 14 are provided on the inner wall of the peripheral side of the installation slide frame 8, and the four locking grooves 14 are grouped in pairs and are symmetrical with the axis of the installation slide frame 8. One end of the limiting column 431 close to the inner wall of the peripheral side of the installation slide frame 8 is slidably plugged into the corresponding locking groove 14, and an arc hole 15 is provided on the peripheral side wall of the fixed seat 11 directly above each arc groove 13, and the other end of the limiting column 431 passes through the corresponding arc hole 15 and extends into the fixed seat 11 and is set as an inclined surface, and a threaded groove is provided on the lower side of the fixed seat 11, and a locking seat 432 that movably contacts the inclined surface of the limiting column 431 is provided in the thread in the threaded groove.

[0038] See also Figure 5 A strip hole connected to the sliding hole is provided on the upper side of the massage seat 41, a connecting block is slidably arranged in the strip hole, the lower side of the connecting block is fixedly connected to the corresponding limiting column 431, and a return spring 433 is commonly arranged between the connecting block and the inner wall of the corresponding strip hole.

[0039] During specific operation, for users with less abdominal fat, the three massage seats 41 can be evenly distributed on the lower side of the mounting slide frame 8, and the massage balls 428 are driven to rotate by the driving motor 91, so that the massage balls 428 can perform massage work on the user's abdomen. When the user is not satisfied with the simple massage effect, before use, the locking seat 432 can be rotated in the reverse direction to make the locking seat 432, which was originally in conflict with the inclined surface of the limiting column 431, move downward, so that the limiting column 431 is released from the limit and moves in the direction away from the corresponding locking groove 14 with the cooperation of the second return spring 433, thereby releasing the lock of the massage seat 41. Then, the user manually pushes the two massage seats 41 that can rotate in the installation slide frame 8 to rotate, so that the two massage seats 41 can be closed with another massage seat 41 fixed in the installation slide frame 8, and then rotates the locking seat 432 forward, so that the locking seat 432 moves up again and conflicts with the inclined surface of the limiting column 431 and drives the limiting column 431 to move in the direction of the corresponding locking groove 14, so that the massage seat 41 is locked again, and then fixed to the user's abdomen again for use. At this time, the three massage seats 41 on the massage mechanism 4 are closed together, as shown in FIG. Figure 7 As shown, all the massage balls 428 can be concentrated in one area for massage, which can better simulate the manual palm massage method, and the single massage surface is larger, which can achieve a better massage effect.

[0040] See also Figure 2 , Figure 3 and Figure 5 The guide assembly 10 includes two connecting columns 101, the upper ends of the connecting columns 101 are fixedly connected to the lower sides of the corresponding connecting ear seats 2, and the lower ends of the two connecting columns 101 are commonly connected to a guide ring 102, and the inner ring of the guide ring 102 is provided with an arc surface protruding outward. The connecting shaft 427 is rollingly connected to the inner ring of the guide ring 102.

[0041] During specific operation, the massage ball 428 is installed on the massage seat 41 through the connecting shaft 427. When the connecting shaft 427 drives the massage ball 428 to rotate, the connecting shaft 427 moves along the inner ring of the guide ring 102. When the massage ball 428 passes through the inwardly protruding arc surface, the connecting shaft 427 will be guided by the arc surface and move toward the radial direction of the installation slide frame 8, thereby causing the slider 421 to move and causing the original radial position of the massage ball 428 on the installation slide frame 8 to change, so that when the massage ball 428 is driven to rotate by the massage seat 41, it can slide along the radial direction of the installation slide frame 8, thereby expanding the massage surface action area of ​​the massage ball 428 and further improving the massage effect.
