Abstract
The invention discloses a push-and-pull switch with a retractable button for home appliances. Currently, most push-and-pull switches can only achieve single back-and-forth movements of stretching and retracting, however, some problems such as button blocking, decentration, incapability of resilience and the like emerge in the actual process of a whole machine assembly. The push-and-pull switch with a retractable button is characterized in that a sliding rod is arranged in the center of a casing, a button which is sleeved on the sliding rod is arranged inside the casing, a spring is arranged between the top of the sliding rod and the button, the outside of the sliding rod is sleeved with a button post which is in linkage with the button, the surface of the sliding rod is provided with a circular groove, a transverse groove is arranged on the button post, a pulley is arranged between the sliding rod and the button, a supporting shaft penetrates through the center of the sliding rod, one end of the supporting shaft is located in the circular groove, and the other end of the supporting rod is located in the transverse groove. The button post and the sliding rod are connected through the pulley, one end of the supporting shaft of the pulley moves in the circular groove and the other end moves in the transverse groove so that clamping stagnation between the button and the inner wall of the casing is avoided when the button stretches and retracts back and forth.
Description
Technical field
The present invention relates to appliance switch, specifically one is used in the telescopic push-and-pull switch of button on household electrical appliance (baking box, steam box).
Background technology
Push-and-pull switch is a kind of purposes control piece very widely, particularly in household electrical appliance.Current most of push-and-pull switches can only be realized single stretching motion back and forth, but in actual final assembly process, tend to encounter a lot of for example buttons stuck, eccentric, cannot resilience etc. Similar Problems, directly affecting complete machine cannot normally work.
Summary of the invention
Technical problem to be solved by this invention is to overcome the defect that above-mentioned prior art exists, and provides a kind of button telescopic push-and-pull switch, with avoid button in motion process, occur stuck, eccentric, cannot resilience etc. phenomenon.
For this reason, the present invention is by the following technical solutions: the telescopic push-and-pull switch of a kind of button, comprise housing and be connected to the overcoat on housing, it is characterized in that, in housing, be provided with a slide bar that is positioned at the center, a set of button on slide bar is housed in housing, between the top of slide bar and button, have a spring, slide bar overcoat have one with the button post of button interlock;
The surface of described slide bar has a cannelure, has a transverse groove on button post, between slide bar and button post, is provided with a pulley, and a back shaft is run through at the center of this pulley, and one end of back shaft is arranged in cannelure, and the other end is arranged in transverse groove.By pulley, button post being connected with slide bar, moves in one end of pulley support axle in cannelure, and the other end moves in transverse groove, avoids button when flexible back and forth and inner walls generation catching phenomenon.
As the further of technique scheme improved and supplemented, the present invention takes following technical measures:
The upper side wall of described transverse groove forms a boss, and lower wall forms a concave station; One upper limit position is formed on the top of described cannelure, the cannelure that is positioned at upper limit position right side forms a step that stops pulley support axle to move right, two left and right lower positions that are arranged side by side are formed on cannelure bottom, lower limit on the right position is lower than lower limit on the left position, be positioned on the cannelure madial wall of lower-left directly over spacing and form a latched position, be positioned at the cannelure formation one anti-down turntable rank in latched position left side;
Under normality, one end of back shaft is arranged in the transverse groove of boss below, in the latched position that the other end is conflicted in cannelure.
Being used in conjunction with of described concave, convex platform and multiple spacing positions, makes pulley support axle when motion flexible, falls back, the generation of the problem such as clamping stagnation while thoroughly getting rid of the motion of pulley support axle; A set of guide vane end stop and on button post is housed in described button and is positioned at the slide block above button post, the chimb of described button column top is positioned between guide vane end stop and slide block, and guide vane end stop is connected on button, slip, guide vane end stop and button post and button interlock.
Described slide block, button post and button realized three's interlock by the cooperation of groove and positioning bar, and the edge of guide vane end stop is useful on the oblique projection being connected on button.
Described cannelure and the same side of transverse groove respectively have one for back shaft, to enter the introducing port in it.
Described overcoat is threaded connection on housing, easy accessibility.
Compared with prior art, the beneficial effect that the present invention has is as follows: avoided button when flexible back and forth and inner walls generation catching phenomenon 1.; 2, on button post, be equipped with corresponding female, boss and multiple spacing positions be set in cannelure, better guarantee pulley support axle in running back and forth without problems such as reversing, clamping stagnations.
Below in conjunction with specification drawings and specific embodiments, the invention will be further described.
