Description
The utility model relates to a kind of switching device that is applicable to electrical control, illumination control, relate in particular to a kind of be applicable to open a period of time after, need close down the wall type vapour lock time-delay button switch of occasion automatically.
At present, with regard to existing many kind that vapour lock time-delay button switch technical scheme is applied for a patent, do not used but all promote so far, reason may be many-sided, its master-plan design is correct, and its certain characteristics are also arranged on the structure, but technically all has certain weak point.At first be that versatility is poor, ubiquity button knob head is too small, as desk-top install and use still can, and just seem not too suitable as present widely used wall type lighting switch.As be applied to Equipment Control and just more demonstrate its weakness, switchtype does not match, and interchangeability is poor.Also there is certain problem, too slow as the on-off action of switch contact in its switch contact in addition, very easily arcing of contact, carbon distribution or scaling loss, thus cause loose contact, easily have an accident, durability is also very poor, and the part technology still is the old-fashioned structure of exposed type, is not suitable for buried installation.
The purpose of this utility model just is to overcome weak point of the prior art, and provides a kind of design more reasonable, and the knob women's head-ornaments are long-pending big, switch contact is swift in motion, and separates thoroughly closed, safe and reliable, wall type vapour lock time-delay button switch durable in use, that interchangeability is strong.
The purpose of this utility model realizes by following measure: an air chamber barrier film is installed between last lower house, the edge of air chamber barrier film is fitted between the lower house, the housing inner chamber is divided into upper and lower two parts, epicoele directly communicates with atmosphere, cavity of resorption is an annular seal space, it communicates with atmosphere by the air flue that is arranged on the lower house, also is processed with one in a side of air flue the valve opening that valve is adjusted in time-delay is housed; The moving plate of leapfrog switch and moving plate spring are installed in the middle part of push rod, and the upper end of push rod contacts with the lower surface of button, and the mesopore that the air chamber barrier film is passed in its lower end lumps together by screw thread and movable agllutination down, and the air chamber spring housing is contained in the movable bottom of piece down; The switch stator is installed on the housing by terminal screw.
Be processed with a through hole respectively on the opposite position of the corresponding two side of upper shell of the present utility model, the tip side of switch stator bends into the housing inner chamber by the through hole of processing on sidewall, and the other end is installed on the housing outer wall by terminal screw.
Time-delay is adjusted valve and is made up of rubber seal piece and adjustment screw.The air chamber barrier film is made by elastomeric material.The switch stator is four groups two, and one group of the top for often opening group, and following one group is normally closed group.
The utility model advantage compared to existing technology is:
1, the leapfrog construction of switch is adopted in the contact folding, can be finishing opening and closing movement in the shortest time (10 milliseconds), and be the double-contact folding, restricted the generation of arcing, avoid the generation of carbon distribution, thereby improved the security reliability of using;
2, adjust valve owing to be provided with time-delay on the annular seal space, make the time of delay switch adjustable by regularly becoming, reference time delay can be adjusted arbitrarily in 1~360 second scope, thereby has enlarged the scope of application of delay switch;
3, the switch stator adopts four two groups of frame modes, makes the utility model realize often opening and normally closed dibit function, thereby has further enlarged use face;
4, because the utility model more reasonable, compact than prior art design, it is strong to make that the utility model also has interchangeability, and long-lived advantage can be widely used in Equipment Control and illumination control field.
Accompanying drawing is a cutaway view of the present utility model.
The utility model is done with detailed description below in conjunction with embodiment (accompanying drawing):
As shown in the figure, the installation panel 1 of switch is installed in the top of upper shell 6 by the mode that is threaded, and a lock nut 2 also is installed on this position.Button head 3, spring 4 and fairlead 5 are installed in the cavity on upper shell 6 tops; Between upper and lower casing 6,10, air chamber barrier film 9 is housed, the edge of air chamber barrier film 9 is fitted between the lower house, the housing inner chamber is divided into two parts up and down, epicoele directly communicates with atmosphere, cavity of resorption is an annular seal space, it communicates with atmosphere by the air flue 12 that is arranged on the lower house, also is processed with a valve opening in a side of air flue 12, by the rubber seal piece with adjust the time-delay adjustment valve 13 that screw forms and be installed in the valve opening; The moving plate 18 of leapfrog switch and moving plate spring 19 are installed in the middle part of push rod 8, the upper end of push rod 8 contacts with the lower end of button head 3, the mesopore that the thread segment that its underpart is set with pad 17 and spring 16 passes air chamber barrier film 9 combines with movable piece 14 down, and air chamber spring 15 is sleeved on the movable bottom of piece 14 down; Be processed with an open-work respectively on the symmetrical position of upper shell 6 corresponding two sides, the tip side of switch stator 7 bends into the housing inner chamber by the open-work on the sidewall, the other end is installed on the housing outer wall by terminal screw 11, switch stator 7 is four two groups, last group for often opening group, and following group is normally closed group.
Operation principle of the present utility model is as follows: adjust time-delay in advance and adjust valve, head presses button, push rod moves down thereupon, the switch moving plate props up support by normally closed stator to be decided, because the move down angle and the supporting point that make the leapfrog spring of push rod change, fulcrum length is shortened by long, spring energy-storage, when extending by the short rightabout again, the accumulation of energy abrupt release of spring institute, promptly fulcrum of spring length is extended to opposite direction, and the switch moving plate is upwards boosted, with the normally opened contact closure, leapfrog this moment switch is finished the task of opening.Meanwhile, the air chamber barrier film also moves down with push rod, and the cavity of resorption air is discharged, and the time of delay switch is adjusted valve by time-delay and adjusts, and return is finished by air inflow and air chamber spring.
