Abstract
Button type is in the same direction as switch, its leading features establish the movable contact on the adjustable shelf under consequent button or reverse button and reset spring's effect, only make rectilinear direction's reciprocating motion, the action of consequent button and reverse button passes through the interlocking mechanism interlocking, this interlocking mechanism is started by installing the piece that promotes in the change button below the axle, the change button is then established between consequent button and reverse button, this kind is in the same direction as the movable contact of switch and does not have the phenomenon of sliding and the wearing and tearing condition with fixed contact between, consequently, contact long service life, contact performance is good, is a novel structure, and operation laborsaving, convenient to use's novel switch in the same direction as switch.
Description
The utility model relates to a kind of two-direction switch of controlling suitable, the contrary direction running of motor conversion.
Known two-direction switch, KO-3 type two-direction switch for example, be to utilize laterally swinging of turn-button, make two groups of movable contacts that are installed on the turn-button axle realize that by the road of falling the para-electric motor is suitable, the conversion of reverse running with two groups of fixed contact contact , And in three groups of fixed contacts respectively.This two-direction switch is in the contact process of movable contact with fixed contact, and movable contact is with existing sliding phenomenon between the fixed contact, and this slippage is to carry out under the effect of movable contact stage clip, and therefore, the contact wearing and tearing are very fast, and useful life is short; Contact after the wearing and tearing makes the contact performance variation of contact again.
The purpose of this utility model provides a kind of contact long service life, and the good two-direction switch of contact performance.
Structure of the present utility model as shown in drawings, wherein:
Fig. 1: the utility model structure chart;
Fig. 2: the monophase machine road of falling para-electric winding diagram;
Fig. 3: the three phase electric machine road of falling para-electric winding diagram;
Fig. 4: adjustable shelf guide frame figure;
Fig. 5: mutual interlocking gear upward view.
This two-direction switch is by base (1), adjustable shelf (2), forward button (3), reverse button (4), turn-button (5), mutual interlocking gear and the road of falling the para-electric form. Install and fix contact (6) on the base (1), totally four arrange, three of every rows, and the adjacent fixed contact (6) of middle two rows is communicated with. Left and right two altogether of adjustable shelfs (2), each adjustable shelf (2) are installed two row's movable contacts (7), and activity adjacent between two rows is touched Head (7) is communicated with, movable contact (7) has holddown spring (8), be located on the adjustable shelf (2), the guide frame (such as Fig. 4) of chute-type is set between the same base of adjustable shelf (2) (1), can be cooperated by the chute on (27,28) the same bases of the projection on the adjustable shelf (2) (1) (29,30) to form, also be provided with back-moving spring (9) in the below of adjustable shelf (2). The road of falling the para-electric is located on the base (1), and for monophase machine and three phase electric machine, its line structure of falling the para-electric is different, and the road of falling the para-electric belongs to known technology, and wiring diagram as shown in Figures 2 and 3. Forward button (3), reverse button (4), turn-button (5) and mutual interlocking gear are located on the lid (10), forward button (3) and reverse button (4) are mobile by thumb-button push rod (11,12) promotion adjustable shelf (2), and be provided with push-button reset spring (13,14), also be provided with locating slot (15,16) and lower locating slot (17,18) on the thumb-button push rod (11,12). Turn-button (5) is located at forward between the button (3) and reverse button (4), and a semicircular pushing block (20) is arranged in the below of turn-button axle (19). Mutual interlocking gear is by right slide plate (21), left skateboard (22), right stage clip (23), left stage clip (24), pushing block (20), upper locating slot (15,16) and lower locating slot (17,18) form, establish thumb-button push rod hole (25 on right slide plate (21) and the left skateboard (22), 26), for thumb-button push rod (11,12) extend through, when turn-button (5) when being in stop position, the two-end-point of pushing block (20) overcomes the right side simultaneously, left stage clip (23,24) spring force And promotes right, left skateboard (21,22) enter lower locating slot (17,18), button (3) and reverse button (4) are locked, and movable contact (7) and fixed contact (6) are thrown off. (5) 90 ° of turn-buttons turn right, pushing block (20) disengages with right slide plate (21), right stage clip (23) is about to right slide plate (21) and releases lower locating slot (17) left, at this moment, forward button (3) release, reverse button (4) is still locked, press forward button (3), it is mobile that thumb-button push rod (11) promotes adjustable shelf (2), movable contact (7) contacted, simultaneously with fixed contact (6), right stage clip (23) further promotes right slide plate (21) and enters the forward button (3) that locating slot (15) And locking has been pressed, in like manner, and to counter-rotation turn-button (5), also can make reverse button (4) release, and forward button (3) is still locked, and presses reverse button (4), and left skateboard (22) can be with further locking of reverse button (4).
The two-direction switch of above-mentioned push button, movable contact are only done the reciprocating motion of rectilinear direction, live Moving contact is with not having sliding phenomenon and abrasion condition between the fixed contact, therefore, the contact long service life, contact performance is good, in addition, and the two-direction switch of this push button, novel structure, rapid operation, easy to use, be a kind of new two-direction switch that has more advance than KO-3 type two-direction switch.
Claims (1)
1, a kind of two-direction switch, has fixed contact, movable contact and the road of falling the para-electric, it is characterized in that: also have the forward button (3) that is located on the lid (10), reverse button (4), turn-button (5) and mutual interlocking gear, turn-button (5) places forward between the same reverse button of button (3) (4), there is the pushing block (20) of a semicircle below of turn-button axle (19), the same left skateboard of this pushing block (20) (22), right slide plate (21), left side stage clip (24), right stage clip (23), thumb-button push rod (11,12) the last location notch (15 on, 16) and following location notch (17,18) constitute mutual interlocking gear together, forward button (3) and reverse button (4) are provided with push-button reset spring (13,14), movable contact (7) is installed in a left side, on right two adjustable shelfs (2), each adjustable shelf (2) is installed two row's movable contacts (7), the movable contact (7) that two rows are adjacent is communicated with, movable contact (7) has holddown spring (8), adjustable shelf (2) is provided with back-moving spring (9), fixed contact (6) is totally four rows, be installed on the base (1), the adjacent fixed contact (6) of middle two rows is communicated with, and between the same adjustable shelf of base (1) (2) the chute-type guide frame is set.
