The present invention relates to a low speed rotating device for mechanical advertising using the Rackett principle. Conventional low-speed rotating devices used as small commercial rotating devices or rotating lights have used small reduction motors, which have shortened lifespan due to motor damage caused by wear caused by high-speed rotation or failure of the reduction gear. It was the cause. This proposal was devised in consideration of the above-mentioned drawbacks, and by eliminating the high-speed rotation part such as the motor, there are few trouble parts caused by abrasion even after long-term use, and there is no possibility of damage like the motor even if it is suspended during use. When described in detail below, based on the accompanying drawings.

In the accompanying drawings,

1 is a small jaw portion formed in the upper part of the inner circumferential wall and subtracts a circular oscillator 2 having the same thickness as the jaw in the part, and the lower part is a rotor inserted in the inner circumference of the stator 3 serving as a housing. On the outer surface of the rotor 1, several slots 4, one of which is deep and the other of which is shallow, are provided, and the lower roll 6 supported by the springs 5 and 5a in this slot 4 is provided. (6a) was installed up and down, respectively.

7 is a wire lead hole formed in the center of the rotor (1), the wire lead hole (7) refers to the power supply line for the light source for lighting (for example, the user, beauty salon, hospital, etc., not shown in the drawing) ) Can be inserted.

8,8a is a vibration interval protruding on both sides of the vibrator 2, the right vibration interval 8 is to receive the motive force, mechanical (reciprocating vibration device by a cam, etc.), electrical (vibration device by an electromagnet) or compression The vibration force can be transmitted by using air (air induction device, etc.), and the left side vibration gap (8a) of the stable spring (10) (10a) in the support frame (9) installed in the stator (3) It is hard. 11 is an adjustment screw to adjust the elasticity of the stable spring (10) (10a) installed on both sides of the support frame (9), by adjusting the amplitude of the oscillator (2) by the adjustment screw (11) You can finely adjust the rotation speed of the).

In this configuration, the present invention is designed to reversibly vibrate the vibration section 8 in the "a" "b" direction in the state of FIG. 3, and as shown in FIG. 4, the vibration section 8 "b" is moved in the direction. When the upper roller 6 of the rotor 1 and the rotor 1 in close contact by the action of the spring 5 also move clockwise in the same direction, the vibration interval 8 as shown in FIG. ) Moves counterclockwise in the direction of "a", the rotor 1 is stopped by the action of the lower roller 6a and the spring 5a of the rotor 1 and only the vibrator 2 is the upper roller 6 ) Is to move in the counterclockwise direction while pushing the slot 4 in the deep direction, which will be described in more detail as follows.

In the third (a) and third (b) degrees, the vibrator 8 moves in the " b " direction as shown in the fourth (a), so that the vibrator 2 moves the upper roller 6 to the rotor 1 Since the slot 4 is pushed in the shallow direction, the top roller 6 is sandwiched between the shallow surface of the slot 4 of the rotor 1 and the vibrator 2 as in the fifth (a). The rotor 1 moves together with the vibrator 2, and at this time, the lower roller 6a is fixed to the spring 5a as opposed to the upper roller 6 as shown in FIG. 5 (b) because the stator 3 is fixed. While pushing slightly, the slot 4 of the rotor 1 is pushed in the deep direction so that the rotational motion of the rotor 1 is not suppressed.

On the contrary, when the oscillation section 8 moves in the direction of “a” as shown in FIG. 6 (a), the vibrator 2 pushes the upper roller 6 in the deep direction of the slot 4 of the rotor 1. As shown in FIG. 7 (a), the upper roller 6 does not attempt to rotate the rotor 1 by a large force, but when the upper roller 6 rotates in the primary “b” direction, the upper roller 6 moves in the shallow direction of the slot 4. 2) as the state of close contact with the "a" direction to some extent, as shown in the 6 (b) the lower roller (6a) is pushed to the shallow side of the slot (4) to be fitted to the inner surface of the stator (3) Therefore, the rotor 1 is stopped and the upper roller 6 is to be idle while slightly compressing the spring (5).

Accordingly, the lower roller 6a acts as a raquel so that the rotor 1 stops, and only the vibrator 2 idles in the " a " direction (counterclockwise).

When the reversible operation in the a, b direction is applied to the vibration section 8 from the outside, the rotor 1 rotates continuously in a clockwise direction, and at this time, the safety is held in the left vibration section 8a of the vibrator 2. By adjusting the elasticity of the spring (10) (10a) to adjust the amplitude of the vibrator (2) it is possible to finely adjust the rotational speed of the rotor (1), which is an adjustment provided on the support (9) of the stator (3) It can be adjusted by tightening or loosening the screw (11).

In addition, the wire lead-in hole 7 in the center of the rotor 1 allows the power lead wire to be drawn in and connected to the lighting lamp, and the reflector or the rotating ball can be directly attached to the rotating side, thereby greatly simplifying the production cost. It is possible to reduce, it is a very practical and useful design that can be used efficiently, such as rotating lights for general stage equipment, warning rotating lights, advertising advertising rotating lights.

Claims (2)

In the structure which arranged several slots 4 which the one side was deep and the other side was shallow in the outer surface of the rotor 1, the roller which supported by the normal spring 5 and 5a in the slot 4 was supported.
