Abstract
The utility model provides a mechanical interlock switch. According to the mechanical interlock switch, a plastic interlock slide block is arranged inside a housing. Through contact and isolation between the plastic interlock slide block and a plastic bulge on a lifting lever, several other buttons bounce when one button is pressed. When the plastic interlock slide block contacts with the plastic bulge, the contact surface is smoother, and the frictional force of the contact surface is much lower. In addition, the weight of an interlock slide sheet prepared from plastic replacing an original metal material is lighter. The interlock slide sheet can move from side to side under tiny external force. Contact is stable, and hand feeling is smooth. The lifting lever, the bulge and the sheet are one-step molding structures. Thus, hand feeling is good, costs can be saved, and the mechanical interlock switch is convenient to produce.

Utility model content
The utility model, for the problems referred to above, provides a kind of mechanical type interlock switch, this mechanical type interlock switch by improve self-lock switch internal structure, reach improve feel, contact stabilization improve, by the little effect of touch.
The utility model is realized by following scheme:
An interlock switch, comprises button, casing cover, driving lever, push-button reset spring, buckle back-moving spring, housing, and described push-button reset spring is between button and casing cover; Described driving lever upper end is connected with button, and lower end is deep in housing through push-button reset spring; In described housing, be provided with plastics interlocking slide block, plastics interlocking slide block is provided with latch hook, and plastics interlocking slide block can move left and right; Described plastics interlocking slide block one end is connected with buckle, and described buckle back-moving spring is between buckle and housing wall; The lower end of described driving lever is provided with plastics projection, and projection contacts with the latch hook of plastics interlocking slide block, and described driving lever below is provided with the movable contact spring that can conduct electricity, and housing wall is provided with the static contact corresponding with movable contact spring.
Preferably, described push-button reset spring is volute spring, can improve the stability that button is pressed the process of upspringing, and avoids spring eccentric and cause loose contact, guarantees that button feel in pressing the process of upspringing is good, contact stabilization.
Preferably, described projection and described latch hook contact-making surface are cambered surface, can reduce the contact area with latch hook, reduce frictional force, thereby make feel more smooth and easy.
Preferably, described driving lever bottom one side is provided with the card of two the parallel movable contact spring clamped upper ends, and described driving lever, projection, card are one-shot forming structure, can accomplish that feel is good, can also be cost-saving, be convenient to produce.
Preferably, described button, driving lever, casing cover, housing form by plastic material.The parts friend hardware of tradition mechanical type self-lock switch forms, and hardware punching press meeting causes burr, and switch is had some setbacks, and after adopting plastic material to form, switch is more smooth and easy.
The beneficial effect that the utility model mechanical type interlock switch can produce is: this mechanical type interlock switch is provided with plastics interlocking slide block in housing, by plastics, interlocking slide block contacts and leaves with the plastics projection on driving lever, reaching a button presses, the effect that several buttons are upspring in addition, described plastics interlocking slide block is when contacting with plastics projection, contact surface is more smooth, the frictional force of contact-making surface is less, and the interlocking slide plate that replaces original metal material to make with plastics, quality is lighter, under the effect once small external force, can move left and right, can accomplish contact stabilization, feel is smooth and easy, described driving lever, projection, card are one-shot forming structure, can accomplish that feel is good, can also be cost-saving, be convenient to produce.
Accompanying drawing explanation
Fig. 1 is the organigram of mechanical type interlock switch.
Fig. 2 is preferably organigram of a kind of button driving lever part.
Fig. 3 is the organigram of plastics interlocking slide block.
Embodiment
Fig. 1 is the structural representation of mechanical type interlock switch provided by the utility model, comprises button 1, push-button reset spring 3, driving lever 2, buckle back-moving spring 4, buckle 5, plastics interlocking slide block 7, casing cover 8, housing 10, base 9.Fig. 2 is preferably organigram of a kind of button driving lever part, comprises static contact 61, movable contact spring 62, card 22 and projection 21.Fig. 3 is the schematic diagram of plastics interlocking slide block.Described push-button reset spring 3 is between button 1 and casing cover 8, driving lever 2 upper ends are connected with button 1, lower end is deep in housing 10 through push-button reset spring 3, in housing 10, be provided with plastics interlocking slide block 7, plastics interlocking slide block 7 is provided with latch hook 71, plastics interlocking slide block 7 can move left and right, and plastics interlocking slide block 7 one end are connected with buckle 5.Buckle back-moving spring 4 is between buckle 5 and the inwall of housing 10, the lower end of described driving lever 2 is provided with the projection 21 of plastics cambered surface, the projection 21 of plastics cambered surface contacts with the latch hook 71 of plastics interlocking slide block 7, the projection 21 of plastics cambered surface can reduce and latch hook 71 between frictional force, thereby prolongation component life, and make to press more flexible.Described driving lever 2 belows are provided with the movable contact spring 62 that can conduct electricity, and its housing 10 inside are provided with corresponding with it static contact 61.
When one of them button is pressed to 1 time, projection 21 parts on driving lever 2 and driving lever 2 move down, the latch hook 71 of projection 21 extruding plastic interlocking slide blocks 7, plastics interlocking slide block 7 is moved right, plastics interlocking slide block 7 right-hand members are provided with buckle 5 and buckle back-moving spring 4, when protruding 21 extruding plastic interlocking slide blocks 7 are to low order end, driving lever 2 continues to move downward, its protruding 21 parts no longer contact with plastics interlocking slide block 7, at this moment buckle back-moving spring 4 can be moved to the left by promotion plastics interlocking slide block 7, realizing this button 1 presses, the effect that other buttons are upspring, in the process that driving lever 2 moves down, can to static contact 61, move by extruding movable contact spring 62, movable contact spring 62 is contacted with static contact 61, corresponding switch connection.
