するものである。 Conventionally, rotation adjustment knobs have been used in electric cookers, radios, televisions, etc., but the knobs can easily turn due to carelessness on the part of the operator. Providing a rotation control device is practiced. For example, FIG. 1 is a side sectional view showing a conventional example of a knob rotation control device.
From the plan view showing the top surface 8 of the case 1 in FIG.
The outer cylinder 7 and the inner cylinder 10 have an upper plate 6 of the knob 5.
The inner end of the inner cylinder 10 inside the outer cylinder 7 is closed by a bottom plate 17, and a hole for supporting the rotating shaft 2 is provided in the center of the bottom plate 17. 2 passes through the inner cylinder 10 and is supported by a chrysanthemum-shaped ring-shaped leaf spring 13 via a coil spring 11. Since the ring-shaped leaf spring 13 is supported by the top 9 of the rotating shaft 2, the coil spring 11 is positioned between the upper surface of the bottom plate 17 of the inner cylinder 10 and the ring-shaped leaf spring 13. And the rotating shaft 2 is
It is arranged to be connected to a resistor, thermostat, etc. within the case 1, and a display scale plate 12 is provided on the upper plate 6 of the knob 5. Further, on the upper surface 8 of the case 1, a recess 3 is formed concentrically with the rotating shaft 2 as an axis.
is formed. FIG. 2 shows the top surface 8 of the case 1.
, a hole 4 is provided in the center of the upper surface 8, a rotation shaft 2 extending upward from inside the case 1 passes through this hole 4, and a knob 5 is provided in the recess 3 of the upper surface 8. A ball 16 provided between the inner cylinder 10 and the outer cylinder 7 of
This ball 16 is provided with a box 14 between the outer cylinder 7 and the inner cylinder 10, and a ball 16 is provided in the box 14 via a spring 15. Pressing to 8. That is, when the knob 5 is rotated based on the rotation axis 2, the ball 16 is rotated on the top surface 8 of the case 1.
The balls 16 slide concentrically around the rotating shaft 2, and the balls 16 align with the respective recesses 3 to control the rotation.

の回転が円滑に行われない。 The above operation is called a step or click, and is well known. However, the box 14 must be fixed between the outer cylinder 7 and the inner cylinder 10 of the knob 5, and the spring 15 and ball 16 must be fixed. It was difficult to assemble as it required several parts. That is, with the knob 5 passed through the rotating shaft 2 on the upper surface 8 of the case 1, the knob 5 is pressed in the direction of the upper surface 8 of the case 1 to prevent the ball 16 from popping out, and the coil spring is attached to the rotating shaft 2. 11 and the ring-shaped leaf spring 13 must be set, making the work difficult. Furthermore, since the pressing direction of the ball 16 is on the axis of the rotating shaft 2, the knob 5 is pushed up by the resistance of the spring 15 that presses the ball 16, and the knob 5 is pushed up.
The knob 5 may be tilted, creating a gap between the knob 5 and the top surface 8 of the case 1, spoiling the aesthetic appearance.
does not rotate smoothly.

A cylindrical ring 20 is provided on the outer periphery of the cylindrical body 18, and the cylindrical body 18 and the cylindrical ring 20 are connected to the outer cylinder 7 and the inner cylinder of the knob 5 at a position where the shaft hole 26 of the knob 5 is supported on the rotating shaft 2. 10, and a part of the outer wall surface of the cylindrical ring 20 and the knob 5.
The knobs 5 are engaged with each other on a part of the inner wall surface of the outer cylinder 7 , and a convex part 21 is formed on a part of the inner wall surface of the cylindrical ring 20 to abut against the outer wall surface of the cylindrical body 18 of the case 1 . The case 1 and the cylindrical body 18 are integrally constructed using a resin material.
Further, the knob 5 is also integrally constructed using a resin material, and a part of the inner wall surface of the outer cylinder 7 of the knob 5 and a part of the outer wall surface of the cylindrical ring 20 are engaged with a pair of parts on the outer wall surface of the cylindrical ring 20. Protruding pieces 22 are provided, and between these protruding pieces 22,
A protruding piece 25 provided on the inner wall surface of the knob 5 is arranged and locked. It is also possible to provide a pair of protrusions 25 on the inner wall surface of the outer cylinder 7 of the knob 5 and lock the protrusions 22 of the cylindrical ring 20 as one. Further, the convex portion 21 provided on a part of the inner wall surface of the cylindrical ring 20 is made of a resin material or a metal material and has elasticity. A pair of notches 23 are provided from the ends, and a plate surface 24 between the notches 23 is provided.
A convex portion 21 is formed on the surface, and the notch 23 makes the plate surface 24 elastic. This cylindrical ring 20 can be integrally molded. Then, to explain the case where it is used in a temperature controller such as a plug-in thermostat shown in FIG. The contact distance of the thermostat is changed by the rotation of the rotating shaft 2, and a heat-sensitive rod 27 that is inserted into the inside of the electric cooker and senses the temperature is installed on one end surface in the longitudinal direction of the case 1. A pair of plug holes 28 into which plug pins of an electric cooker are inserted are provided on the end face portion of the case 1 located on both sides of the heat-sensitive rod 27, and a power cord 29 is provided on the other end face of the case 1. Connected. On the top surface of the case 1, a cylinder 18 and a cylinder 18 are provided.

表示目盛板１２を設けることになる。 The top 9 of the rotating shaft 2 is approximately equal to the diameter of the rotating shaft 2, and the diameter of the rotating shaft 2 below the top 9 is equal to the diameter of the rotating shaft 2.
Since the diameter is slightly smaller than the diameter of the coil spring 11, once the chrysanthemum-shaped ring-shaped leaf spring 13 is inserted under the top portion 9, it will not come off due to the drag force of the coil spring 11. That is, the assembly involves positioning the cylindrical ring 20 on the outer periphery of the cylindrical body 18 of the case 1, and then attaching the knob 5 to the rotating shaft 2, the coil spring 11, the ring-shaped leaf spring 13, and the upper surface of the upper plate 6 of the knob 5.
A display scale plate 12 will be provided.

価なものとなり、組立て時間も短縮される。 As described above, the rotation control device for the knob 5 of the present invention only requires the knob 5 to be installed on the rotating shaft 2 after the cylindrical ring 20 is set on the outer periphery of the cylindrical body 18 of the case 1. Therefore, the assembly work is extremely easy. Furthermore, since the elastic force of the convex portion 21 of the cylindrical ring 20 is in the radial direction of the rotating shaft 2,
Since no force is applied in the axial direction and the case 1 and knob 5 are always located in a parallel state, the aesthetic appearance is not spoiled. Furthermore, although parts such as the ball 16 and the spring 14 were conventionally required, only the cylindrical ring 20 is required, which reduces the number of parts, reduces the cost, and shortens the assembly time.
