Description

Technical Field

[0001] This utility model relates to the field of shampoo bed technology, specifically to a reciprocating massage device applied to a shampoo bed. Background Technology

[0002] With the continuous development of the medical and nursing industries, shampoo beds, as important equipment in hospitals, nursing homes, and home care, are receiving increasing attention for their functionality and comfort. In recent years, a number of new shampoo devices have emerged, including some with massage functions. For example, Chinese utility model patent application number 201820539681.2 discloses a shampoo massage bed mechanism. This mechanism uses a reciprocating motion mechanism installed on the bed, within which a massager is mounted. The reciprocating motion mechanism drives the massager to move back and forth, thus massaging the user's back. This not only expands the massage area but also improves user comfort, relieving stress and fatigue.

[0003] In the above structure, the reciprocating motion mechanism is driven by a gear and rack mechanism. Specifically, the gear is mounted on the rotating shaft, and the motor drives the rotating shaft to rotate. The rotating gear meshes with the rack to achieve the drive. However, since guide wheels need to be installed at both ends of the rotating shaft and then fitted onto guide rails for guidance, in this mechanism, the rotating shaft not only bears the lateral traction force but also the longitudinal support force. Especially during massage, in order to achieve an effective massage effect, the massager needs to have sufficient pressing pressure. The reverse force generated by the pressing pressure will be applied to the rotating shaft, which may cause the rotating shaft to bend and deform, thereby affecting the guidance of the guide wheels. Moreover, after a long period of time, the fit between the gear and rack may become misaligned or the meshing may become loose, thus affecting the driving effect. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a reciprocating moving massage device for use on a shampoo bed.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A reciprocating massage device for use on a shampoo bed includes a bed frame body, a massage device movably mounted on the bed frame body, and a reciprocating drive device mounted below the massage device. The bed frame body has a travel cavity with a top opening in the middle, and a rectangular support frame is provided at the opening of the travel cavity. Guide grooves extending horizontally in the front-back direction are provided on both sides of the support frame. Guide wheels are provided on both sides of the massage device, and the massage device slides in the guide grooves on both sides through the guide wheels. The bottom of the massage device is also provided with a linkage block for connecting the reciprocating drive device. The reciprocating drive device is provided with a linkage seat, and a slot is provided in the middle of the linkage seat. The linkage block is inserted into the slot from top to bottom. The reciprocating drive device drives the linkage block to move the massage device back and forth by pushing the linkage block through the linkage seat.

[0007] Furthermore, the guide groove is disposed on the inner side of the two side frames of the support frame.

[0008] In this invention, the reciprocating drive device includes two rotating shafts rotatably mounted in the stroke cavity, a toothed belt rotatably engaged between the two rotating shafts, a slider fixedly connected to the toothed belt, and a drive motor connected to one of the rotating shafts. The two rotating shafts rotate synchronously through the toothed belt, and the drive motor drives the slider to move back and forth through the toothed belt.

[0009] Furthermore, the toothed belt has two sections, which are respectively engaged with the two ends of the rotating shaft. The two sides of the stroke cavity are also provided with slide rails extending horizontally in the front and rear directions. The sliders on the toothed belts on both sides are respectively slidably engaged with the slide rails on both sides. The linkage seat is fixedly connected between the two sliders. When the sliders move, they drive the linkage seat to move back and forth.

[0010] Furthermore, the two rotating shafts are parallel to each other and are respectively located at the front and rear ends of the stroke cavity. Gears are fixedly installed on each rotating shaft near both ends. The two toothed belts are respectively engaged with the gears on the same side of the rotating shafts. The rotating shafts drive the toothed belts to rotate through the gears.

[0011] Furthermore, the drive motor is mounted on the side wall of the bed frame body, and the drive motor is connected to one of the rotating shafts via a gear commutator.

[0012] In this utility model, the massage device includes a support plate and a massager installed at the bottom of the support plate. The front end and rear end of the bottom of the support plate are respectively provided with support rods. The guide wheel is rotatably mounted on both ends of the support rod. Massage arms are provided on both sides of the massager. The massage arms pass through and protrude from the support plate from bottom to top. Multiple massage wheels are rotatably arranged on the massage arms.

[0013] Furthermore, the linkage seat includes two horizontally spaced push rods, with a gap hole between the two push rods forming the slot. The top of the linkage block is fixedly connected to the support plate, and the bottom of the linkage block is inserted between the two push rods.

[0014] This utility model has the following advantages and beneficial effects:

[0015] The support frame set at the opening of the travel cavity is mainly used to support the massage device and provide guidance. The linkage seat is set on the reciprocating drive device below the massage device. The massage device moves back and forth by pushing the linkage rod through the linkage seat. This separates the drive component and the support component, thus avoiding the support component from affecting the drive component. The two work independently and do not interfere with each other, which improves flexibility and structural stability, and makes maintenance and upkeep more convenient. Attached Figure Description

[0023] like Figures 1 to 3 As shown, this embodiment discloses a reciprocating massage device applied to a shampoo bed, including a bed frame body 1, a massage device 2 movably mounted on the bed frame body 1, and a reciprocating drive device 3 mounted below the massage device 2. Specifically, the bed frame body 1 has a stroke cavity 10 with a top opening in the middle, and a rectangular support frame 11 is provided at the opening of the stroke cavity 10. The two side frames of the support frame 11 are provided with guide grooves 110 extending horizontally in the front-back direction. The guide grooves 110 are preferably located on the inner side of the two side frames. The two sides of the massage device 2 are respectively provided with guide wheels 20. The massage device 2 slides in the guide grooves 110 on both sides through the guide wheels 20. The bottom of the massage device 2 is also provided with a linkage block 21 connected to the reciprocating drive device 3. The reciprocating drive device 3 is provided with a linkage seat 30. The middle of the linkage seat 30 is provided with a slot 300. The linkage block 21 is inserted into the slot 300 from top to bottom. The reciprocating drive device 3 drives the massage device 2 to move back and forth by pushing the linkage block 21 through the linkage seat 30.

[0024] In this embodiment, the reciprocating drive device 3 includes two rotating shafts 31 rotatably mounted in the stroke cavity 10, a toothed belt 32 rotatably engaged between the two rotating shafts 31, a slider 34 fixedly connected to the toothed belt 32, and a drive motor 33 connected to one of the rotating shafts 31. The two rotating shafts 31 rotate synchronously through the toothed belt 32, and the drive motor 33 drives the slider 34 to move back and forth through the toothed belt 32. Specifically, in order to improve the smoothness of the movement of the slider 34, two toothed belts 32 are provided and are respectively engaged at both ends of the rotating shafts 31. Slide rails 35 extending in the front-back horizontal direction are also provided on the two side walls of the stroke cavity 10. The sliders 34 on the two sides of the toothed belt 32 slide in engagement with the slide rails 35. The linkage seat 30 is fixedly connected between the two sliders 34. When the slider 34 moves, it drives the linkage seat 30 to move back and forth. The slide rails 35 can also improve the guiding effect for the back-and-forth movement of the linkage seat 30.

[0025] Furthermore, the two rotating shafts 31 are parallel to each other and are respectively located at the front end and rear end of the stroke cavity 10. Gears 311 are fixedly installed on each rotating shaft 31 near both ends. The two toothed belts 32 are respectively engaged with the gears 311 on the corresponding side of the rotating shaft 31. The rotating shaft 31 drives the toothed belts 32 to rotate through the gears 311.

[0026] Furthermore, the drive motor 33 is mounted on the side wall of the bed frame body 1. Since the driving direction of the drive motor 33 is perpendicular to the rotation direction of the rotating shaft 31, the drive motor 33 is connected to one of the rotating shafts 31 by a gear commutator 36.

[0027] In this embodiment, the massage device 2 includes a support plate 22 and a massager 23 installed at the center of the bottom of the support plate 22. The front and rear ends of the bottom of the support plate 22 are respectively provided with support rods 221. The guide wheels 20 are rotatably mounted on both ends of the support rods 221. Specifically, the massager 23 has massage arms 24 on both sides. The massage arms 24 pass through and protrude from the support plate 22 from bottom to top. Multiple massage wheels 25 are rotatably arranged on the massage arms 24. The massager 23 is a mature prior art. The specific working principle of the massager 23 can be referred to the massager 23 disclosed in a massage shampoo bed provided by patent application number 201720463934.8, so it will not be described in detail here.

[0028] Furthermore, the linkage seat 30 includes two horizontally spaced push rods 301, with a gap between the two push rods 301 forming the slot 300. The top of the linkage block 21 is fixedly connected to the support plate 22, and the bottom of the linkage block 21 is inserted between the two push rods 301. When the massage device 2 needs to move forward, the rear push rod 301 pushes the linkage block 21; conversely, if it needs to move backward, the front push rod 301 pushes the linkage block 21. To improve structural stability, two linkage blocks 21 are provided, and they are respectively located on both sides of the bottom of the support plate 22.

[0029] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
