Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand-held pine serge machine, and more particularly to a hand-held pine surge machine that has an improved support structure suitable for supporting an anti-vibration spring and a drive motor.

The configuration of a hand-held pine surge machine can be roughly divided into a vibration part, a vibration isolation part, and a main body part.

The support structure of the vibration isolator and drive motor of a conventional hand-held pine surge machine will be explained with reference to FIGS. 5 and 6 and FIG. 4b.

The drive motor 104 has one end of the protruding side of the shaft 105 connected to a convex rib 107 integrally formed on the main body case 106 and a spring support 108 that supports the vibrating section.
A plurality of screws 109 and washers 11 are inserted through the
It is screwed on by 0.

Further, at the other end of the drive motor 104, an elastic ring-shaped elastic body 111 is disposed in a gap between the two divided main body cases 106a and 106b.
Controls vibration and stabilization of the drive motor 104.

In addition, the main body case 106a, 106b is divided into two parts.
is engaged by a claw etc. formed integrally with the part,
Preventing the cap from coming off is achieved by a cap 112 that is screwed onto the screw located in the longitudinal direction of the length and the drive motor 4 mounting screw 109.

The support mechanism further includes a vibration isolating part 102 that absorbs hand vibration, a main body part 103 containing a drive motor 104, a flexible shaft 116, a vibration isolating spring 117, and a vibration isolating spring cover 118.

The conventional drive motor 104 support structure described above not only requires a large number of parts, but also has drawbacks in ease of assembly, making it very expensive.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hand-held pine surge machine that has a vibration-proofing part and a drive motor support structure that has a small number of components and can improve assembly efficiency.

A feature of the present invention is that a spring seat is integrally molded on both of the two divided main body cases, and a cap made of synthetic resin or the like that contacts the spring seat is engaged to hold the vibration-proof spring. There is a handheld pine surge machine.

In the best embodiment of the hand-held pine surge machine of the present invention, as a support structure for the drive motor, the front and back directions of this part are positioned by ribs that protrude integrally with the main body case, and the radial direction of this part is supported by an elastic Holds through an elastic body, and also holds a vibration-proof spring.
By integrally forming a spring seat with the main body case, the main body case is divided into two parts together with the drive motor 4, and a plurality of claws integrally formed in the part prevent the main body case from coming off. This is done by a cap that comes into contact with the outer periphery of the spring seat.

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, and 4a.

The hand-held pine surge machine is roughly divided into three parts: a vibration part 1 that controls vibration, a vibration isolation part 2 that absorbs hand vibration, and a main body part 3 that houses a power supply part such as a drive motor 4.
It is classified as

The vibrating part 1 includes an eccentric weight 13, a weight shaft 14, a bearing metal 15, etc., and the weight shaft 14
A flexible shaft 16 made of a coil spring is connected to the shaft 5 of the drive motor 4.

The vibration isolating part 2 consists of a vibration isolating spring 17 and a vibration isolating spring cover 18 that covers the outer surface of the vibration isolating spring 1.
One end of the spring 7 is fixed to the vibrating part 2, and the other end circumscribes a spring seat 19 formed integrally with the main body case 6, and a tapered surface 29 is formed on the outer periphery of the spring seat 19.

The drive motor 4 is positioned in the longitudinal direction by ribs 20 and 21 that protrude integrally with the main body case 6, and is integrated in the radial direction with the main body cases 6a and 6b, which are divided into two via an elastic body 22. It is fixed together with the vibration isolating spring 17 by engagement of the plurality of formed pawls 23 and the like.

In addition, the main body case 6 can be prevented from coming off by using the power cord 24 installed at the longitudinal end of the length and the claw 2 nearby.
3, a convex pawl 26 that engages in a corresponding manner with a groove 25 installed on the surface of the spring seat 19, and a tapered surface 30 that corresponds to and abuts on a tapered surface 29 on the outer periphery of the spring seat 19. Cap 2 made of synthetic resin etc.
7, and the cap 27 also serves to reinforce the spring seat 19, which is subjected to stress when the main body is in use.

Further, the power switch 28 is fixed to the main body case 6 by an integrally protruding engaging claw, or is attached by screws or the like.

Next, the operation will be explained. When the power switch 28 is operated, the drive motor 4 rotates, and the rotation is transmitted to the weight shaft 14 and the eccentric weight 13 via the flexible shaft 16, causing the vibrating part 1 to vibrate. , the user presses the vibrating section 1 against the human body to perform a partial massage.

According to the above-described embodiment of the present invention, the spring seat 19 that supports the vibrating part 1 and the vibration isolating part 2 is integrally formed with the main body case to hold the parts, and the spring seat 19 is also attached to the main body case 6 when supporting the drive motor 4. The integrally protruding rib and elastic body 22 are used to engage the main body case 6, and to prevent the main body case 6 from coming off, there is a tapered surface 30 that engages in correspondence with the tapered surface 29 on the outer periphery of the spring seat 19. This is done by engaging the cap 27 with the claw 23 formed on the main body case 6.

Further, in the engagement between the cap 27 and the outer periphery of the spring seat 19, the tapered face-to-face alignment is adopted, so that the engagement between the concave groove 25 of the main body case 6 and the cap convex pawl 26 is made to work in a direction that makes it difficult to disengage. This not only eliminates the need for screws, washers, etc. that have been used in the past, but also enables the locking of the main body case 6 to be configured without screws. As you can see, we were able to significantly reduce the number of parts, and also significantly improve assembly workability.

As described above, the present invention provides two
The divided main body case and the vibrating part containing the eccentric weight are connected via an elastic support tube, and the weight shaft supporting the eccentric weight and the drive motor shaft are connected by a flexible shaft, etc. In a device that generates vibration through rotation, a spring seat is integrally formed on both of the two divided main body cases, and a cap that abuts across both spring seats is held in such a way that the spring seat holds the vibration isolating spring. Because it is engaged with the anti-vibration spring, it is possible to obtain sufficient holding force for the anti-vibration spring with a simple configuration, and the number of components is greatly reduced compared to the conventional one.
Moreover, it was possible to provide a hand-held pine surge machine with significantly improved assembly workability.
