Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a vibrating pine surgical machine, and more particularly to the structure of a vibrating pine surgical machine that has a vibrating part attached to the tip of a grip that is easy to assemble.

(Background of the invention) As a vibrating pine surger, one in which a vibrating part is attached to the tip of the grip part is known. This type of vibrating unit consists of an unbalancer, a pine surge body, etc. driven by a motor, and the treatment is performed by pressing the pine surge body against the affected area, such as the shoulder or lower back, while vibrating the body. The parts are required to be easy and robust to assemble.

A conventional pine surgeon of this type has a mounting body 5 in which an unbalancer is housed, as shown in FIG. 5, for example.
A vibrating part 56 is formed by attaching the head cover 52, soft ring part 53, case part 54, etc., which constitute the pine surge body 51, to the front part and outer circumferential part of 0 with screws 55, etc., and then the vibrating part 56 is The spring seat 58 is press-fitted into the rear end of the resilient coil spring 57, and then the spring seat 58 is attached to the tip of the grip portion 59. However, in such conventional means, since the outer diameter D of the spring seat 58 was larger than the inner diameter d of the case part 54, after the pine surge body 51 was assembled on the outer peripheral part of the mounting body 50, the spring seat 58 was attached behind the spring 57. It must be fixed to the end, and in that case, press-fitting or caulking is performed using a tool such as a jig for the fixing work, so the pine surge body 51 may be damaged by the jig or There were problems such as oils adhering to it and making it dirty. In particular, this type of pine surge body 51 is made of a soft material to ensure good contact with the human body. This is easily damaged or soiled, and since the pine surgery body 51 is the most important and conspicuous member that comes into contact with the human body for treatment, if it gets damaged or soiled during assembly, the commercial value of the pine surgery body 51 will be reduced. Because it will disappear,
Assembling it requires careful attention.

(Purpose of the invention) The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a vibrating pine surger with excellent assemblability of the vibrating part. More specifically, in order to improve the contact with the human body, we have removed the vibrating pine surger, which is made of soft materials such as soft synthetic resin, and is not likely to be damaged or contaminated during assembly. The purpose is to provide.

(Summary of the invention) The present invention includes an unbalancer that is driven by a motor via a flexible shaft, and a mounting body in which the unbalancer is installed, in which the vibrating part is attached to the tip of the grip part. At the same time, the mounting body is attached to the tip of the resilient coil spring, and a spring seat to be attached to the tip of the grip is attached to the rear end of the coil spring. The back case part of the Pine Surge body is made of a soft material with an inner diameter larger than the outer diameter.
It is fitted onto the spring seat and the resilient coil spring to be attached to the outer periphery of the attachment body. With this configuration, the vibrating section can be easily attached to the tip of the grip section via the resilient coil spring. In particular, in order to improve contact with the human body, the pine surge body is made of a soft material, and after attaching a spring seat for attachment to the grip part to a coiled spring for elasticity, the body is fitted onto the spring seat or coil spring. The pinsurge body is inserted into the body and attached to the outer periphery of the attachment body, thereby preventing the pine surge body from being damaged or soiled by jigs or the like during assembly.

(Example) Next, an example of the present invention will be described with reference to the drawings.

Figure 1 is a perspective view of the vibrating pine surger, Figure 2
The figure is a cross-sectional view, and this pine sergeer is formed by attaching a vibrating part 5 to the tip of a rod-shaped grip part 1 consisting of half cases 2 and 3 through a bellows-like flexible tube 4. ing. 6 is a motor housed in the front part of the grip part 1, 7 is a cooling fan, and 10 is a sliding switch part.
0 slides through three positions: vibration, thermal vibration, and OFF.

Reference numeral 8 indicates a rotary switch section for setting the rotation speed of the motor 6, and reference numeral 9 indicates a volume section, which is obliquely provided at the rear end corner of the rear enlarged portion 1a of the grip section 1. 11 is a substrate for fixing the volume section 9;
1, and then inserting the fitting part 8a of the switch part 8 into the rotating shaft 12 protruding from the volume part 9.
The switch part 8 is fixed by engaging the engaging part 8b with the locking part 13. By fixing the switch part 8 and the volume part 9 separately in this way, the switch part 8 and the volume part 9 can be fixed. The fitting part 8a and the rotating shaft 12 are corrected for positional deviations due to manufacturing errors, etc.
The switch part 8 can be fixed at the best position by absorbing the damage between the parts. The rotation axis X of the switch part 8 mounted in this way intersects the longitudinal axis Y of the grip part 1, so that the grip part 1 can be held with one hand. This makes it easier to operate the switch part 8 with the other hand, and prevents the switch part 8 from rotating unnecessarily in conjunction with the vibration of the grip part 1, thereby preventing the rotational speed of the motor 6 from going out of order. Reference numerals 17 and 18 are air intake holes and exhaust holes provided at the tip and rear ends of the grip part 1. When the fan 7 rotates, outside air is sucked in through the intake hole 17, cooled the motor 6, and then exhausted. The exhaust air is exhausted through the hole 18, and by setting the exhaust hole 18 at this position, the exhaust air is prevented from hitting the human body and cooling the human body during use. 19 is a connection code.

The vibrating section 5 includes a pine surge body 23 on the front side and outer periphery of the mounting body 22 on which the unbalancer 21 is disposed.
It is formed by attaching. 24 is the motor 6 mentioned above.
It is a flexible shaft consisting of a coil spring driven by a coil spring, and an unbalancer 21 is attached to the tip thereof.The unbalancer 21 is rotated by the drive of the motor 6, and the pine surge body 23
vibrates. Reference numeral 30 denotes a resilient coil spring for the vibrating section 5, the rear end of which is attached to the tip of the grip section 1 via the spring seat 25, and the attachment body 22 is attached to the tip of the spring seat 25. is installed.

The pine surge body 23 consists of a back case part 26a, a front case part 26b, a soft ring part 27 installed between the back case parts 26a and 26b, a head cover 28, an elastic plate 29 made of foam material, etc. A heating section 31 made of a heat transfer plate made of aluminum or the like is provided in a part of the housing. The case parts 26a, 26b, the soft ring part 27, etc. are made of a soft material such as soft synthetic resin or rubber in order to improve contact with the human body. 34
is a heater of the heating section 31, and 35 is a lead wire.
The side of the heating section 31 in which the heater 34 is built-in is considerably heavier than the opposite side. Therefore, when the pine surger is placed on a desk or the like, the heating section 31 is placed on the bottom side as shown in FIG. In this state, the switch section 8 is placed on the upper side, thereby preventing the switch section 8 from touching the ground and being damaged or erroneously operated.

Three flange portions 32 are provided protruding from the outer circumference of the mounting body 22 (see FIG. 3).
A screw rod 33 is screwed onto 2. This flange part 3
2 is located in front of the unbalancer 21. The outer diameter D (see Fig. 4) of the spring seat 25 is:
The inner diameter d of the case portion 26a of the pine surge body 23 is slightly smaller than the inner diameter d of the case portion 26a, and therefore, as shown in FIG. Attach by press-fitting with a jig, etc., and then attach case 2.
6a is fitted into the spring seat 25 and the spring 30, and the case 26a, the soft ring part 27, the head cover 28, etc. are assembled on the front surface and outer periphery of the mounting body 22 to form the pine surge body 23, and then the spring seat 2 is assembled.
5 is assembled by fixing it to the tip of the grip part 1. In this way, the vibrating part 5 is constructed by attaching the spring seat 25 in advance to the rear end of the resilient coil spring 30 to which the mounting body 22 is attached, and then assembling the pine surge body 23 on the outer periphery of the mounting body 22. It will be done.

(Effects of the Invention) As explained above, the vibrating pine surger according to the present invention allows the vibrating part 5 to be easily and firmly attached to the tip of the grip part 1, and in particular, the pine surger body 23 can be attached easily and firmly. After attaching the spring seat 25 to the rear end of the resilient coil spring, the back case part 26a is inserted into the spring seat 25 and the spring 30 to attach the attached body 2.
2, so when attaching the spring seat 25 to the coil spring 30 using a jig or the like,
The pine serge body 23 is not damaged or soiled, and the pine surge body 23 made of a soft material that is easily damaged in order to make good contact with the human body can be neatly assembled without any defects.
