Description

Rotary switch

This creation is a rotary switch, especially a switch used in electrical appliances to adjust the number of segments or turn off in a rotating manner.

Check, the conventional rotary switch used in electrical appliances, as described in Taiwan's new patent M343903, is mainly a structure in which a rotating seat is assembled on a fixed seat, and the rotating seat can be rotated in several stages, so that the rotating seat can be rotated in several stages. Mainly divided into the following two types: 1. The rotating seat is provided with a plurality of zigzag grooves, and the fixing seat is provided with a snap-fitting piece with a spring, and the snap-fitting piece can be locked in the slot. When the rotating seat is rotated, different slots can be locked by the locking pieces, thereby adjusting the number of segments. However, every time this structure is rotated to switch the number of segments, the tip of the jagged slot will be worn out. After a lot of use, the tip will be flattened, making it difficult to use for a long time. 2. A plurality of card slots are provided on the fixed seat, and the rotating seat is provided with a spring and a steel ball, and the steel ball is locked in the card slot by the spring support. When the revolving seat is rotated to the next stage, the steel ball will be pressed back close to the axis of the revolving seat until it corresponds to the next slot before being pushed back to lock by the spring. Although this structure solves the problem of wear, the steel ball parts used are small and difficult to assemble, and the steel ball may slip if vigorously shaken.

This creation is to improve the above-mentioned shortcomings of the prior art and design a rotary switch that is easier to assemble and not easy to wear. The main system includes: a fixing seat with a accommodating space with a plurality of card slots, and a first perforation at the bottom; a rotating seat, which includes: a rotating shaft with a second perforation at the center of the rotating shaft; Through the second perforation; two positioning members, one end of the positioning member is arc-shaped, and the other end has a groove, respectively sleeved at both ends of the spring; the rotating shaft passes through the first perforation, and is assembled in the accommodating space, The two positioning members are supported outwardly by the spring and can be precisely locked in the card slot. When the rotating seat is rotated to the next stage, the two positioning pieces will first be squeezed by the edge of the accommodating space toward the center of the rotating shaft until they correspond to the next slot respectively, and then pushed back by the spring to achieve the effect of switching the stage. .

Please refer to the first to seventh figures, it is a rotary switch, including: a fixed seat 10, the fixed seat 10 is provided with an accommodating space 101, the accommodating space 101 has a plurality of card slots 102, the bottom has a first perforation 103; a rotating seat 20, which includes: a rotating shaft 21, the center of the rotating shaft 21 has a second through hole 211; a spring 22 through the second through hole 211; two positioning members 23, one end of the positioning member 23 is The other end has grooves, which are respectively sleeved on both ends of the spring 22; the rotating seat 20 passes through the first through hole 103 through the rotating shaft 21, and is assembled in the accommodating space 101. The two positioning members 23 are formed by The spring 22 is supported outwards to be precisely locked in the slot 102; and a conductive sheet 30 is fixed on the bottom of the rotating seat 20, the two ends of the conductive sheet 30 are inclined downward; a base plate 40 is assembled on the fixed In the base 10, an arc-shaped electrode sheet 41 is fixed on one side of the substrate 40 in the center, and a plurality of electrical connection sheets 42 arranged at intervals are fixed on the other side; by rotating the rotating base 20, the conductive sheet 30 can be controlled One end is in contact with the arc-shaped electrode sheet 41, and the other end is optionally in contact with one of the electrical connection sheets 42 to form an electrical connection to achieve the effect of switching the number of segments.

When the rotating seat is to be rotated and switched to the next stage, the two positioning members will be squeezed toward the center of the rotating shaft by the edge of the accommodating space, until they respectively correspond to the next slot, and then pushed back by the spring.

In addition, the center of the rotation shaft 21 can be provided with a protruding column 212; the substrate 40 can be provided with a third through hole 401 in the center of the base plate 40; the protruding column 212 can be inserted into the third through hole 401 to make the structure more stable. The fixing base 10 can be further provided with two hooks 104; the substrate 40 can be further provided with two locking slots 402, and the hooks 104 can be locked in the slot 402, so that the substrate 40 and the fixing base 10 can be locked. Solid one.

According to the concept of this creation, when it is desired to switch between the three strengths and the closed four segments, the accommodating space 101 of the fixing seat 10 is a polygon with eight convex corners, and each convex corner forms a card slot 102. The polygon is a regular octagonal shape; the substrate 40 is fixed with three electrical connection pieces 42 corresponding to the three adjacent grooves 102, and the arc-shaped electrode piece 41 is fixed to the three opposite grooves 102; the remaining two The card slot 102 does not correspond to any electrical connection or electrode plates. When the conductive sheet 30 is turned to a slot with no corresponding contact sheet or electrode sheet, the switch is turned off; when one end is in contact with the arc-shaped electrode sheet 41 and the other end is in contact with one of the contact sheets 42, the switch can be switched Number of segments.

According to the above structure, the following effects and advantages can be obtained: (1) The number of switching stages in this creation depends on the two positioning pieces 23 sheathed at both ends of the spring 22 and locked in the slot 102, while the 23 positioning pieces designed by this creation are sheathed on the spring 22, positioning pieces The part 23 is always in the second perforation 211, so it is easy to assemble and not easy to fall off as far as the traditional spring and steel ball combination is concerned. (2) When the accommodating space 101 of this creation has an octagonal cross-section, it can switch between three strong and weak and close four segments. According to the design of this creation, not only can the rotating seat 20 be continuously rotated clockwise to switch the number of segments , The rotating base 20 can also be rotated counterclockwise to achieve the effect of not setting any direction to limit the number of switching segments.

In summary, this creation does have a breakthrough structure and improved design creation content, while at the same time it can achieve industrial utilization and advancement, and this creation has not been seen in any information that can be known to the public, and It is novel. When it complies with the provisions of the Patent Law, Yan filed a new patent application in accordance with the law. I implore the Jun Jugui Examiner to grant a legal patent right. I really pray.

Only the above is only one of the preferred embodiments of this creation, and the scope of implementation of this creation cannot be limited accordingly; that is to say, all equal changes and modifications created in accordance with the scope of the patent application for this creation should still be covered by this creation patent.
