[Industrial applications]

  The present invention relates to a stopper device for a rotary operation knob, and particularly to a rotation limit of the operation knob. The present invention relates to a stopper device that is convenient for changing the position.

[0002]

[Prior art]

  Conventionally, a rotary switch or detent mechanism attached to the operation surface of communication equipment, etc. For rotating parts that have a stopper, it is best to rely on the stopper attached to the part itself. Generally, it is impossible to change the stopper position, so the rotation limit It was necessary to repurchase the parts themselves that were in different positions. In addition, the parts themselves Some types allow you to change the position, but when changing the After removing it from the work panel, change the stopper position and then operate the component again. It is difficult to change it on the operation surface because it has to be attached to the channel. Met.

[0003]   In addition, there are some that have a stop mechanism between the operation surface and the operation knob. When the operation knob is removed from the parts to change the position, the stop mechanism itself comes apart. There was an inconvenience that

[0004]

[Problems to be solved by the device]

  SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems of the conventional device, and a rotary operation. To change the stop position of the knob, do not remove the parts one by one as before. Stop position by rotating the position setting ring by simply removing the operating knob. An object of the present invention is to provide a stopper device for a rotary operation knob that can be easily changed. .

[0005]

[Means for Solving the Problems]

  In order to achieve the above-mentioned object, the present invention puts the rotary operation knob at the stopper position. And a part having a rotary operation rod to be attached to the operation panel, and the rotary operation rod. Operation knob having a first protrusion for preventing rotation attached to the work rod, and the first protrusion It has a second protrusion that comes into contact with the A position setting ring attached to the first projection and the second projection. The position at which the rotation of the rotary operation knob is blocked by It features an adjustable structure corresponding to the mounting position of the ring.

【Example】

  Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS.

[0007]   1 to 3, as a substrate for mounting a rotary switch, etc. The operation panel 1 is provided with a mounting hole 3, and the mounting hole 3 is used to utilize the rotary hole. Parts 6 such as switches are screwed in the usual way. Such as the rotary switch The rotary operation rod 6A of the component 6 has an operation knob having a first protrusion 5A for preventing rotation. Only 5 is installed.

[0008]   The position setting ring 4 is attached between the operation panel 1 and the operation knob 5. This position The setting ring 4 is made of, for example, plastic and has a plurality of small protrusions 4 on its back surface. A are provided at substantially equal intervals. In addition, on the surface of the operation knob 5, the rotation blocking Second projection 4 for preventing rotation of operation knob 5 by contacting with first projection 5A for stopping B is integrally provided.

[0009]   A space for accommodating the position setting ring 4 is secured in the operation panel 1. A recess 1A is provided for storing the small projection 4A in the recess 1A. The same number of small holes 2 as that for the small protrusions 4A are provided at equal intervals. Therefore, the operation When the position setting ring 4 is attached to the small hole 2 of the panel 1, the position of the second protrusion 4B The position can be freely selected and set. That is, the normal use of the operation knob 5 With it removed from the state, the position of the second protrusion 4B can be arbitrarily and easily selected. It is possible to choose.

[0010]   Since the engagement between the small hole 2 and the small protrusion 4A utilizes friction, the position setting ring 4 is Both can be fixed firmly by pushing firmly, but if it is not so strong, the second collision Since it is difficult to remove it when changing the position of the origin 4B, the frictional engagement between the two is smooth. It is desirable to set it as not strong. In that case, position in normal use It is desirable to take measures to prevent the setting ring 4 from floating. Operation knob 5th The end surface 5B of the first projection 5A makes a light contact with the position setting ring 4 in a normal use state. Therefore, the floating can be prevented. Also, for the same purpose, use the operation knob. A pressing rod 5C is integrally formed on a part of the groove 5, and the end of the pressing rod 5C is formed. The surface 5D also prevents the position setting ring 4 from rising.

[0011]   In the embodiments described above, the small holes on the operation panel are set to small projections, and the position setting Even if the small projection of the ring is changed to a small hole, the same effect as described above can be achieved. Also small The hole is not limited to a circle, and it can be a square or an ellipse, as long as it is similar to the cross-sectional shape of the small protrusion. .

[0012]

[Effect of device]

  As described above, according to the present invention, the position setting between the operation panel and the operation knob is set. Since the ring is provided, the position setting ring can be rotated with only the operation knob removed. The position of the second protrusion can be arbitrarily selected and changed by replacing As a result, the stop position of the operation knob can be easily changed.
