Abstract

The utility model relates to a positioning structure for a knob switch. A positioning rod sheathed with a spring is arranged on a rotary disc which is arranged in a circular slot of a base and is combined with a knob which is pivoted on a convex ring of the base; the head of a positioning rod is constantly abutted on the wall of the circular slot under the action of spring force, and the wall of the slot has a groove; the base can have grooves having the quantity which is matched with the quantity of knob sections according to the sections desired by the knob. Force for moving the positioning rod can be directly controlled by selecting the springs having different elastic coefficients, and accordingly, the force for rotating the knob can be effectively controlled. The utility model has the advantages of simple structure, easy assembly, clear and accurate position fixing, unqualified product rate reduction and manufacturing cost reduction.

Description

The rotary switch location structure

The utility model is the switch of relevant electronic correlation product knob option location usefulness, especially has the rotary switch location structure of flexible backstay.

Rotary switch is widely used in the electronic product, as the usefulness of option and turning circuit.General rotary switch be the elastic arm made with plastic material as align member because plastic cement elasticity is relatively poor, locating effect is not clear, quality is of poor quality.Other has the align member that utilizes steel ball and spring matched combined, though can obtain the preferred positioning effect, its production and assembling difficulty, relative have a higher manufacturing cost.General rotary switch location structure uses upward and disappearance is gone up in manufacturing in order to improve, and after the creator studies again and again, finishes the utility model eventually.

Main purpose of the present utility model is providing a kind of simple in structure, easy good rotary switch location structure of versatility that reaches of assembling.

Another purpose of the present utility model is providing a kind of rotary switch location structure clearly demarcated, that can reduce fraction defective of locating.

A kind of rotary switch location structure of the utility model is characterized in that, comprises that pedestal, rotating disk and knob form; This rotating disk is placed in the circular groove of pedestal, and combines with the knob that is articulated in pedestal circular groove opposite side, can be by the knob driven rotary; This rotating disk is provided with the backstay of a socket spring; The bar head of this backstay is subjected to the cell wall of the power perseverance of spring against circular groove, and this cell wall is established groove; When backstay went to groove, the bar head promptly stretched into and makes knob obtain the location in the groove.

Wherein this rotating disk is provided with an axostylus axostyle and a lamellar body, and this axostylus axostyle and lamellar body are respectively equipped with groove and hole and are incorporated into therebetween for the backstay of socket spring; This backstay is established baffle ring, and this baffle ring perseverance is subjected to the thrust of spring only to be against the inboard in the hole of lamellar body, and this bar head is extended in the outside, hole or shrink in the hole.

Wherein this knob is articulated on the bulge loop ring wall of this pedestal.

Wherein this pedestal is provided with the groove quantity that matches according to the required hop count of knob.

Wherein this lamellar body is by extending on the rotating disk periphery.

Other purposes of the present utility model, effect and embodiment see also graphic being described in detail as follows, wherein:

Fig. 1 is the utility model three-dimensional appearance schematic diagram.

Fig. 2 is the utility model perspective exploded view.

Fig. 3 is another perspective exploded view of the utility model.

See also Fig. 1, Fig. 2 and shown in Figure 3, the utility model rotary switch location structure is made up of pedestal 10, rotating disk 20 and knob 30; This rotating disk 20 is placed in the circular groove 11 of pedestal 10; One knob 30 is articulated on bulge loop 12 ring walls of pedestal 10 circular grooves 11 opposite sides; The hole 201 that two bolts 40 pass rotating disk 20 is bolted in the screw 301 of knob 30, and knob 30 is combined with rotating disk 20; This rotating disk 20 is provided with axostylus axostyle 21 and extends a lamellar body 23 on periphery 22, and this axostylus axostyle 21 and lamellar body 23 are respectively equipped with groove 211 and hole 231 and are incorporated into therebetween for the backstay 25 of a socket spring 24; This backstay 25 is established baffle ring 251 and bar head 252, and these baffle ring 251 perseverances are subjected to the low inboard that is against the hole 231 of lamellar body 23 of the thrust of spring 24, and this bar head 252 is extended in 231 outsides, hole or shrink in the hole 231; The cell wall 13 of these pedestal 10 circular grooves 11 is provided with groove 14; The lamellar body 23 of this rotating disk 20 is placed in rotatable activity in the cell wall 13, and the bar head 252 of its backstay 25 is resisted against on the cell wall 13 by the thrust perseverance of spring 24 also.When knob 30 drives rotating disk 20 rotations,, can make knob 30 obtain the location if the bar head 252 of backstay 25 stretches out when being resisted against in the groove 14 outside the hole 231; When knob 30 drove rotating disk 20 rotation again, bar head 252 promptly was resisted against on the cell wall 13 in the retraction hole 231 again, just stretched out again and was resisted against in the groove 14 up to forwarding groove 14 places again to, made knob 30 location of reentrying.

The backstay 25 that the utility model utilizes spring 24 and plastic cement to make is incorporated on the rotating disk 20, because of backstay 25 has the auxiliary of spring 24, when being subjected to knob 30 to drive the time spent of doing of rotating disk 20 rotations, cooperate the design of cell wall 13 inner groovies 14, can do free toward covering motion, with clear, the definite positioning action of pedestal 10 generations.The utility model can be selected the spring 24 of different coefficient of elasticity for use, and with the strength size of control drive backstay 25, and then effectively control handle 30 rotates required strength.The utility model pedestal 10 can be provided with the groove 14 of requirement, with the usefulness as multiple option location according to the required hop count of knob 30.The utility model is simple in structure can be the design of monomer modularity, assembling easily and versatility good, can know clearly demarcated location, increase the stability of product, the fraction defective that reduces product and reduction manufacturing cost and make keep in repair more convenient and efficient.

The above record only for utilizing the embodiment of the utility model technology contents, anyly is familiar with modification, the variation that this skill person uses the utility model to do, and all belongs to the claim of the utility model opinion, and is not limited to those disclosed embodiments.

In sum, the utility model and known rotary switch location structure have evident difference, and have multinomial effect enhancement, have closed in novel patent requirement, earnestly ask early to grant a patent, with Jiahui society.
