Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a roller massager. Background Technology

[0002] A roller massager includes a roller, rollers rotatably mounted on the roller, and a drive motor that drives the roller to rotate. The drive motor is controlled by a circuit board and a control switch. The circuit board and the drive motor are located on opposite sides of the roller and are electrically connected by conductive wires. For example, Chinese utility model patent application number 201821421951.6 requires connecting the two hand grips and then laying wires, which is a rather unreasonable structural layout. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects of the prior art. This utility model provides a roller massager with a hollow threaded design, which avoids the bulky shape caused by the thread passing through the outside, saves design space, and makes the product smaller and more beautiful.

[0004] This utility model discloses a roller massager, including two opposing handles and a roller rotatably disposed between the two handles. A plurality of rollers are rotatably mounted on the roller. One handle has a circuit board and a battery for circuit control, while the other handle has a drive motor for driving the roller's rotation and a charging base for charging the battery. The circuit board also has a control switch for controlling the operation of the drive motor. The battery and control switch are electrically connected to the circuit board. The roller is characterized by having a hollowed-out hole in the center to form a wire through which a conductive wire passes, allowing the drive motor and charging base to be electrically connected to the circuit board.

[0005] A further feature of this invention is as follows: the roller includes a first cylinder and a second cylinder that are separately inserted and connected. The first cylinder is provided with a first mounting plate and a first shaft. The second cylinder is provided with a second mounting plate and a second shaft that mates with the first shaft. The first shaft and the second shaft mate to form a hinge frame. Several hinge frames are spaced apart along the circumferential direction, and each hinge frame is provided with a hinge shaft. The roller is rotatably mounted on the hinge shaft.

[0006] A further feature of this invention is that each of the two handles is provided with a support base, the roller is rotatably mounted on the support base, and a rod is also inserted between the two support bases. The rod passes through a threading hole and is locked to the two support bases.

[0007] A further feature of this invention is that a limiting surface is provided on the rod body, and a locking plate that cooperates with the limiting surface to restrict the rotation of the rod body is provided on the support base.

[0008] A further feature of this invention is that the roller is provided with a plurality of raised ribs spaced apart along the circumference.

[0009] A further feature of this invention is that the second cylinder is provided with a worm wheel that rotates synchronously with it, and the drive motor is provided with a worm segment, which is linked and cooperates with the worm wheel.

[0010] The specific beneficial effects of this utility model are as follows: the drive motor drives the roller to rotate, which in turn drives the roller to rotate, thereby achieving a massage effect. Furthermore, the roller can rotate relative to each other, making the massage effect better and preventing skin abrasion. By setting the center of the roller as a wire hole, the bulky shape caused by the conductive wire running from the outside is avoided, saving design space and making the product smaller and more beautiful. Moreover, it can be disassembled more finely during transportation, improving the convenience of transportation and reducing transportation costs. Attached Figure Description

Detailed Implementation

[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: In the description of this utility model, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "rear", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] This utility model discloses a roller massager, including two opposing handles 1 and a roller 2 rotatably disposed between the two handles 1 (the handles 1 are preferably triangular to facilitate hand grip and allow for internal space, and the two triangular handles 1 are more stable and less prone to tipping when on a flat surface). Several rollers 3 are rotatably disposed on the roller 2. One handle 1 is provided with a circuit board 4 for circuit control and a battery 5, and the other handle 1 is provided with a drive motor 6 for driving the roller 2 to rotate and a charging base 7 for charging the battery 5. The circuit board 4 is also provided with a control switch 8 for controlling the operation of the drive motor 6. The battery 5 and the control switch 8 are electrically connected to the circuit board 4. In this utility model embodiment, the roller 2 has a hollowed-out hole 9 to form a wire hole, and a conductive wire 50 is also included. The conductive wire 50 passes through the wire hole 9 to electrically connect the drive motor 6 and the charging base 7 to the circuit board 4.

[0014] Using the above technical solution, the drive motor 6 drives the roller 2 to rotate, which in turn drives the roller 3 to rotate, thereby achieving the massage effect. The roller 3 can rotate relative to each other, making the massage effect better and preventing skin abrasion. Furthermore, by setting the middle of the roller 2 as a threading hole 9, the roller 2 will not cause the conductive wire to get tangled when it rotates. Moreover, there is no need to set an additional shell to connect the two handles 1. Its structural layout is also more reasonable. In addition, it can be disassembled more subdivided during transportation, improving the convenience of transportation and reducing transportation costs.

[0015] The roller 2 includes a first cylinder 21 and a second cylinder 22 that are separately connected and interlocked. The first cylinder 21 is provided with a first mounting plate 211 and a first shaft 212. The second cylinder 22 is provided with a second mounting plate 221 and a second shaft 222 that mates with the first shaft 212. The first shaft 212 and the second shaft 222 cooperate to form a hinge frame. Several hinge frames are spaced apart along the circumferential direction, and each hinge frame is provided with a hinge shaft 10. The roller 3 is rotatably mounted on the hinge shaft 10. The separately connected first cylinder 21 and second cylinder 22 facilitate the installation of the hinge shaft 10 and the roller 3 by simply placing the hinge shaft 10 on the hinge frame.

[0016] Each of the two grips 1 is provided with a support base 20. The roller 2 is rotatably mounted on the support base 20, and a rod 201 is also provided between the two support bases 20. The rod 201 passes through the wire hole 9 and is locked to the two support bases 20. The rod 201 is provided with a limiting surface 2011. The support base 20 is provided with a locking plate 202 that cooperates with the limiting surface 2011 to restrict the rotation of the rod 201. The two grips 1 can be locked by the rod 201, thereby preventing the two grips 1 from rotating relative to each other. The structure is simple and easy to assemble. The locking plate 202 can be fixed to the support base 20 by screws.

[0017] The roller 3 is provided with a number of raised ribs 31 spaced apart along the circumference, which can increase the massage effect.

[0018] The second cylinder 22 is provided with a worm wheel 30 that rotates synchronously with it, and the drive motor 6 is provided with a worm section 40. The worm section 40 and the worm wheel 30 are linked and cooperated. The cooperation between the worm wheel 30 and the worm section 40 can increase the torque and generate the force reversal, making its layout more convenient.
