Description

Leg rubbing and scraping massage mechanism

The invention relates to a massage appliance, in particular to a leg rubbing and scraping massage mechanism.

With the improvement of people’s living standards, people are paying more and more attention to physical and mental relaxation. Therefore, various types of massage equipment have appeared on the market. Leg massage equipment is one of them. At present, the leg massage equipment on the market, other The structure is more complicated, the production and processing are inconvenient, and the massage action for the legs is only a simple linear pressing action, and it can only press and massage a certain part of the leg, and it cannot achieve a multi-directional massage. The massage effect needs to be improved. .

In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a leg rubbing and scraping with simple structure and reasonable design, which can perform all-round rubbing and massage on the inner side of the user's leg, so that the user can obtain a better massage experience. Massage agency.

For this reason, the present invention is implemented by adopting the following scheme:

A leg rubbing and scraping massage mechanism has: a frame and a drive motor, two first kneading boards are fixedly installed on both sides of the frame, and a second kneading board is arranged between the first kneading boards, The drive motor is in transmission connection with a rotating shaft. A scraping cam is provided on the left and right sides of the rotating shaft. The middle part of the rotating shaft is connected with an eccentric wheel. One end of the swing arm is hinged, and the other end of the swing arm is hinged on the frame.

An output shaft of the drive motor is connected with a worm, the worm is meshed with a worm wheel, and the worm wheel is connected with the rotating shaft.

The two swing arms are symmetrically arranged on the left and right sides, and are connected together by a connecting rod. The two ends of the connecting rod are connected with a fixing seat, and the fixing seat is connected with a second kneading board.

By adopting the above technical solution, the present invention has the advantages: 1. Simple structure and reasonable design, which can realize large-scale production; 2. By setting the scraping cam on the left and right sides of the rotating shaft, the back side of the user's leg can be scraped. For massage, the cooperation of the eccentric wheel and the swing arm can drive the second kneading board to reciprocate in both the horizontal and vertical directions, so that the second kneading board can simulate a more reasonable movement trajectory, and then perform the operation on the inner side of the user's leg. The rubbing massage effectively improves the massage effect of the entire organization and provides a better user experience.

With reference to Figure 1, the present invention discloses a leg rubbing and scraping massage mechanism. The leg rubbing and scraping massage mechanism has a frame 8 and a drive motor 3. A first rubbing plate 1 is fixedly installed on both sides of the frame 8. The outer side of the drive motor 3 is limited and protected. A second rubbing plate 2 is provided between the two first rubbing plates 1, and the drive motor 3 is in transmission connection with the rotating shaft 5. In this embodiment, the output shaft of the drive motor 3 and the worm Connected, the worm meshes with the worm wheel, and the worm wheel is connected with the rotating shaft 5. By controlling the action of the driving motor 3, the rotating shaft 5 can be driven to rotate through the transmission of the worm gear and the worm. The rotating shaft 5 is provided with scraping cams 6 on the left and right sides. , When the rotating shaft 5 rotates, it can drive the scraping cam 6 to rotate, and then scrape and massage the back side of the user's leg.

Referring to Figure 2, the first kneading board 2 and the second kneading board 2 are assembled on the frame 8, the middle of the rotating shaft 5 is connected with the eccentric wheel 4, the eccentric wheel 4 is provided with two symmetrical left and right, the eccentric wheel 4 and the second The kneading board 2 is connected, and when the eccentric wheel 4 rotates, the end of the second kneading board 2 connected to it will be driven to rise and fall in the vertical direction.

1 and 3 at the same time, the second kneading board 2 is hinged with one end of the swing arm 10, and the other end of the swing arm 10 is hinged on the frame 8. Specifically, two swing arms 10 are provided symmetrically, and pass The connecting rods 9 are connected together. The two ends of the connecting rod 9 are connected with a fixing seat 11, and the fixing seat 11 is connected with the second kneading board 2. The swing arm 10 will guide the movement of the second kneading board 2 and guide the second kneading board. 2 also moves in the horizontal direction, thereby realizing the reciprocating movement of the second kneading board 2.

The movement mode of the second kneading board 2 is similar to a crank-rocker mechanism. Refer to FIG. 4, which is a cross-sectional view taken along the radial direction of the eccentric wheel 4, in which the position of the frame 8 is fixed to serve as a fixed connecting rod. , The eccentric wheel 4 takes the rotating shaft 5 as its axis, and rotates 360 degrees around the rotating shaft 5 as a crank, the swing arm 10 is a rocker swinging within an angle, and the second kneading board 2 serves as a connecting rod. One end is connected to the eccentric wheel 4 and the other end is hinged to one end of the swing arm. Therefore, the eccentric wheel as a crank and the swing arm as a rocker are connected by the second kneading board 2 and drive the movement of the second kneading board 2, so that the second The kneading board 2 can continuously massage the inside of the user's legs in the horizontal and vertical directions, and makes the movement track of the second kneading board 2 more reasonable, thus effectively improving the massage effect of the entire mechanism and providing better Massage experience.
