The present invention relates to a massaging device, more particularly to a positioning structure of plastic disk in the massaging device.
Conventional massaging devices, such as the one disclosing in Taiwanese Patent No.: M362693, titled “eccentrically rotated massaging device,” has an inner curved lip-shaped edge at an opening of a massaging cover, and the lip-shaped edge is used to touch the user's body with its resilience to increase the massaging area and further provide a comfortable massaging process. However, the conventional massaging device is disadvantageous because (i) the massaging cover is connected with a connecting unit and a rotating plate that has a polygonal hole. The rotating unit is driven by a motor with a shaft that is configured to plug into the polygonal hole. Although it results a quick assembly and disassembly, the connection between the massaging cover and the rotating unit may be too tight if the polygonal hole is too small, while the massaging cover may fall off if the polygonal hole is too large; (ii) the massaging cover has a ladder-shaped hole and the driving unit has a through hole, and a securing unit is used to pass through the ladder-shaped hole and through hole. When the massaging cover is conducting massaging activities, the massaging cover may generate a lateral force to the driving unit, so the securing unit may not be securely engaged with the driving unit; and (iii) since the rotating unit is connected with the massaging cover only through the shaft's insertion into the polygonal hole, when the massaging cover is conducting massaging activities, a lateral force is generated to the shaft to break the driving unit and further increase the wear inside the rotating unit. Therefore, there remains a need for a new and improved positioning structure in the massaging device to overcome the problems stated above.
To solve the problems stated above, the present invention provides a positioning structure of a plastic disk in a massaging device may include a massaging unit, a connecting unit and a locking unit. The massaging unit has a protruding block that has a through hole. A bowl-shaped portion is formed at one end of the protruding block and an elastic ring is formed at an enlarging end of the bowl-shaped portion. An inner recessed slot is formed at outer periphery of the through hole of the bowl-shaped portion. One end of the connecting unit has a receiving space that is used to receive the protruding block of the massaging unit. The connecting unit has a fixed hole aligned with the through hole, and a plurality of positioning slots are circularly formed at outer periphery of the fixed hole of the connecting unit. A guiding inclined surface is formed inside the receiving space of the connecting unit and the guiding inclined surface is used to tightly attach with the massaging unit. The locking unit has a head portion and a tubular unit extending therefrom. The tubular unit of the locking unit passes through the through hole and fixed hole, and the head portion of the locking unit can be received in the inner recessed slot of the massaging unit to form a elastic compression to achieve an anti-leaking effect between the massaging unit and the locking unit. A screw is used to secure the tubular unit to connect the massaging unit and the connecting unit. Also, the connecting unit has a cover near the fixed hole, and top portion of the cover has a flat portion to cover the opening of the fixed hole to protect the screw therein.
The present invention further includes a driving device having a rotating shaft, and rear end of the rotating shaft has a plurality of positioning pieces, and a stopping block is protrudingly formed at outer surface of the positioning piece. The positioning piece of the driving device is used to plug into the positioning slot of the connecting unit, and the stopping block is received by the receiving space of the connecting unit to quickly engage the driving device and the massaging unit. When the massaging unit needs to be replaced, the connecting unit can be pulled to cause the positioning piece to shrink inwardly, so the massaging unit can be easily replaced. Also, a ring slot is recessedly formed at outer periphery of the positioning slot of the connecting unit and a restricting ring is protrudingly formed at outer periphery of the rotating shaft at a eccentric plate. The restricting ring is configured to plug into the ring slot of the connecting unit to prevent the connecting unit from overly bending the positioning piece.
The main objective of the present invention is that one end of the connecting unit has a receiving space that is used to receive the protruding block of the massaging unit, and the connecting unit has a fixed hole aligned with the through hole, and a plurality of positioning slots are circularly formed at outer periphery of the fixed hole of the connecting unit; the positioning piece of the driving device is used to plug into the positioning slot of the connecting unit, and the stopping block is received by the receiving space of the connecting unit to quickly engage the driving device and the massaging unit.
The second objective of the present invention is that the receiving space that is used to receive the protruding block of the massaging unit, and the connecting unit has a fixed hole aligned with the through hole, so that the head portion of the locking unit can be squeezed into the inner recessed slot of the massaging unit, and the screw can be inserted into the fixed hole of the connecting unit to secure the massaging unit and the connecting unit, and prevent the massaging unit and the connecting unit from falling off.
The third objective of the present invention is that the ring slot is recessedly formed at outer periphery of the positioning slot of the connecting unit and a restricting ring is protrudingly formed at outer periphery of the rotating shaft at a eccentric plate; the restricting ring is configured to plug into the ring slot of the connecting unit to prevent the connecting unit from overly bending the positioning piece.
