Abstract

The utility model relates to a rotary switch for an electric device, which comprises a casing (1), a cover plate (2), a static storage sheet (3), a movable contact piece (4), a rotary rod (5) and a rotary seat (6). The rotary seat (6) is provided with a through hole (7), wherein, the interior of which is provided with a spring (8), wherein, both ends of which are respectively provided with a ball (9) which is contacted with the inner surface of the casing (1); the inner surface of the casing (1) is formed by a plurality of circular arc-shaped lug bosses (10) which are connected ends to ends; a pit (11) is formed between two circular arc-shaped lug bosses (10) which are connected. The utility model has the advantages of flexible rotation, beautiful appearance and material saving.

Description

A kind of rotary electrical equipment switch

The utility model belongs to appliance switch, especially belongs to a kind of rotary electrical equipment switch.

At present, the structure of traditional on the market rotary electrical equipment switch as shown in Figure 1 and Figure 2, the rotating mechanism of this kind appliance switch is to comprise gear A, jacking block B, spring C and groove D, when gear A is rotated, jacking block B is pressed among the groove D, when turning to certain angle, jacking block B ejects the teeth groove that enters gear A again, and the realization movable contact spring is connected with static contact; But there is following shortcoming in this structure: the frictional force that rotating mechanism need overcome is bigger, rotates dumb smooth and easyly, boss will be set in addition constructing groove D on shell, so the volume of switch is bigger, makes difficulty, waste material, and profile is not attractive in appearance.

The utility model provides a kind of and rotates flexibly, good looking appearance, the less electrical equipment rotary switch of volume.

The utility model is achieved by the following technical solution: it comprises shell, cover plate, electrostatic-stored piece, movable contact spring, swingle and rotating seat, wherein static contact is installed on the cover board, swingle is fixed on the rotating seat end face, movable contact spring is installed on the swingle, on rotating seat, have through hole, the through hole the inside is placed with spring, respectively there is a ball at the two ends of spring, ball contacts with the inner surface of shell, the inner surface of shell is joined end to end by several arc cams and forms, and two link to each other forms pit between the arc cam.

Another solution of the present utility model is put case and is: it comprises shell, cover plate, electrostatic-stored piece, movable contact spring, swingle and rotating seat, wherein static contact is installed on the cover board, swingle is fixed on the rotating seat end face, movable contact spring is installed on the swingle, it is characterized in that having on rotating seat through hole, the through hole the inside is placed with spring, and respectively there is a ball at the two ends of spring, ball contacts with the rounded internal surface of shell, and the inner surface of shell is provided with several grooves.

The utility model compared with prior art has following advantage: ball is realized rolling with the inner surface of shell and is contacted, and frictional force is less, therefore rotates flexibly, need not spend bigger strength; Shell mechanism is comparatively simple, and is easy to manufacture, saves material.

Below in conjunction with accompanying drawing the utility model is done detailed explanation:

Fig. 1 is the structure chart of traditional rotary switch;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is a structural representation of the present utility model;

Fig. 4 is the B-B profile of Fig. 3;

Fig. 5 is another embodiment of the present utility model.

As Fig. 3, shown in Figure 4, the utility model comprises shell (1), cover plate (2), electrostatic-stored piece (3), movable contact spring (4), swingle (5) and rotating seat (6), wherein static contact (3) is installed on the cover plate (2), swingle (5) is fixed on rotating seat (6) end face, movable contact spring (4) is installed on the swingle (5), it is characterized in that on rotating seat (6), having through hole (7), through hole (7) the inside is placed with spring (8), respectively there is a ball (9) at the two ends of spring (8), ball (9) contacts with the inner surface of shell (1), the inner surface of shell (1) is joined end to end by several arc cams (10) and forms, and two link to each other forms pit (11) between the arc cam (10); During operation, rotate swingle (5), swingle drives movable contact spring (4) and rotates, two balls (9) are under the effect of spring (8), remain with the arc cam (10) of shell (1) inner surface and contact, when ball (9) entered pit (11), movable contact spring (4) was realized the connection of two static contacts (3).

As shown in Figure 5, another kind of execution mode of the present utility model has through hole (7) on rotating seat (6), through hole (7) the inside is placed with spring (8), respectively there is a ball (9) at the two ends of spring (8), ball (9) contacts with the rounded internal surface of shell (1), and the inner surface of shell (1) is provided with several grooves (12), the shape of groove (12) can be circular arc, can be triangle, also can be trapezoidal.
