The spacing device of the present invention is used to adjust the spacing between the head massager body, characterized in that to adjust the spacing between the body by moving the connecting mechanism through the drive mechanism.

The head massager generally includes a first body and a second body, and moves the connecting mechanism by a driving mechanism, and the connecting mechanism enables adjustment of the size such as to close or move the distance between the first body and the second body. To help the convenience of each user.

The following specific embodiment will be described in more detail with respect to the spacing device of the present invention and a massager having the control device.

1 to 6, according to the first embodiment of the head massager of the present invention, the first body 110 and the second body 120 are divided into two parts, and are generally surrounded by hemispherical shape. Massage device is installed inside the hemispherical shape (not shown).

The first body 110 and the second body 120 is composed of two independent parts, the first body 110 and the second body 120 to adjust the distance between the first body 110 and the second body 120 Positions in contact with both ends of the body 120 are connected to each other through the gap adjusting device 130.

1 to 5, one of the spacing device 130 is taken as an example, and how the spacing device 130 is implemented in detail.

The gap adjusting device 130 includes an external case module, a drive mechanism and a connection mechanism mounted on the external case module.

One end of the connecting mechanism is connected to the first body 110 and / or the second body 120, and the other end is connected to the driving mechanism, and the first mechanism 110 is operated by operating the connecting mechanism with the driving mechanism. ) And the gap between the second body 120.

According to this embodiment, the connecting mechanism includes a first connecting piece 131 and a second connecting piece 132, the driving mechanism includes a rotary knob 133, the rotary knob 133 is an outer case The control unit 1333 exposed to the outside of the module and the annular connecting portion 1334 installed inside the outer case module.

One end of the first connecting piece 131 is rotatably connected to the first body 110, and the other end is rotatably connected to the edge of the annular connecting portion 1334 of the rotary knob 133.

One end of the second connecting piece 132 is rotatably connected to the second body 120, the other end is rotatably connected to the rim of the annular connecting portion 1334 of the rotary handle 133, The connection positions of the first connecting piece 131, the second connecting piece 132, and the rotary knob 133 are separated on the same straight line, and are also symmetrical with the center of the rotary knob 133.

Specifically, the first protrusion 111 may be installed inside the first body 110, and the first mounting hole 1331 may be installed in the connection portion 1334 of the rotary knob 133.

First connection holes 1311 corresponding to the first protrusion 111 and the first mounting hole 1331 are installed at both ends of the first connection piece 131, respectively, through screws, rivets, and the like. By being connected, the first connecting piece 131 may be connected between the first body 110 and the rotary knob 133 and may rotate corresponding to the first body 110 and the rotary knob 133.

The positioning mechanism is also possible in other manners, such as for example a positioning groove.

The first body 110 and the second body 120, between the base 135 and the first body 110, to rotate corresponding to the outer case module, the base 135 and the second body 120 A guide mechanism is installed between the guides to guide rotation of the first body 110 and the second body 120.

The guide mechanism is a set of first guide pieces 1352 parallel to each other provided on the base 135 and second guide pieces parallel to each other provided on the first body 110 and the second body 120. (112) (122).

The first guide piece 1352 and the second guide piece 112 and 122 are arranged to guide each other to guide rotation of the first body 110 and the second body 120.

In order to prevent the first body 110 and the second body 120 from being separated from the outer case module, stoppers 1353 are installed at both ends of the base 135, and correspondingly, the first body Hooks 113 and 123 that are properly coupled to the stopper 1353 are installed at the 110 and the second body 120.

By preventing the detachment of the hooks 113 and 123 through the stopper 1353, the first body 110 and the second body 120 do not leave the outer case module.

The two bases 135 can also be connected to the third body 140, which is convenient for the user to wear.

The third body 140 and the base 135 may be formed in an integrated structure connected by fixing in the manner of welding, adhesion, screws, rivets, bolts, or the like.

In order to increase the convenience of the user wearing, the inside of the base 135 may also be provided with a washer (Washer) (150).

At the time of assembly, one end of the first connecting piece 131 and the second connecting piece 132 is rotated on the first protrusion 111 and the second protrusion 121 of the first body 110 and the second body 120, respectively. After the connection is possible, one end of the hooks 113 and 123 installed on the first body 110 and the second body 120 are inserted from both sides of the base 135 to the inside of the stopper 1353, respectively. In addition, the second guide piece 112 and 122 inside the first body 110 and the second body 120 and the first guide piece 1352 on the base 135 to be combined with each other, the guide Do it.

Thereafter, the other ends of the first connecting piece 131 and the second connecting piece 132 are respectively connected to the first mounting hole 1331 and the second mounting hole 1332 of the rotary knob 133. To the rotatable handle 133 by aligning the open hole 1342 of the outer case 134 with the rotary knob 133, and then hooking the hook 1341 of the outer case 134 into the groove 1351 of the base 135. And the outer case 134 and the base 135 are hooked to allow the outer case module to be assembled at a connection position of the first body 110 and the second body 120, and also to the first body. The body 110 and the second body 120 may prevent the external case module from slipping. At this time, the operation part 1333 of the rotary knob 133 is exposed to the outside of the outer case, and helps to rotate well.

When it is necessary to adjust the distance between the first body 110 and the second body 120, the operating portion 1333 of the rotary knob 133 rotates from the outside is the rotation of the connecting portion 1334 of the rotary knob 133 By interlocking with each other, the first connecting piece 131 and the second connecting piece 132 is moved, and the first body 110 and the second body 120 as shown in FIG. Adjust the spacing by moving away as shown in.
