Abstract

The utility model provides a time-delay cut-off pull switch which is mainly added with a moving rotating disk and a disk-shaped spring on the base of the prime pull switch. The second circuit of the switch comprises a contact strip, a conducting strip, a contact card and conducting wires to realize the delaying power cut-off function. The utility model is especially suitable for the public places of office buildings, corridors and stairways and also suitable for the family use.

Description

Time-delay cut-off pullswitch

The utility model belongs to the electric switch technical field, is the improvement to pulling switch.

Present pulling switch only has two kinds of functions of instantaneous open and close, though this switch is simple in structure, but locate as office building, meeting room, stair corridor etc. in that some occasion is not too convenient, when the people turns off the light when leaving at night, dark, very inconvenient, therefore, usually occur altar lamp in office building, the corridor, the waste electric energy damages bulb.

The purpose of this utility model is the above-mentioned defective that will overcome pulling switch, adorns a delay cut-off device in switch, switch is beaten extinguished shelves, and through after a while, after people left the scene, lamp just extinguished, and provides amenities for the people like this, saves electric energy.

The utility model mainly is that pulling switch is improved.With the fixing noose of an end of the mandrel of pulling switch and rotating disk, the other end at mandrel overlaps a movable disk again, one end and the mandrel of one time-delay clockwork spring are fixed, the other end and movable disk are fixed, contact chip of having on the movable disk surface and second circuit that contacts card, conducting sheet, lead composition switch.Be further described below in conjunction with accompanying drawing.

Accompanying drawing 1 is a front view of the present utility model; Fig. 2 is Fig. 1 C-C cutaway view; Fig. 3 is Figure 1A-A cutaway view; Fig. 4 is the B-B cutaway view of Fig. 1; Fig. 5 is circuit theory diagrams of the present utility model.Among the figure: 1,3-contact card, 2-diode, 4, the 6-contact chip, 5-reduction torsion spring, 7-mandrel, 8-pull handle, 9-shell, the 10-clockwork spring of delaying time, 11-rotating disk, 12-movable disk, 13,14-conducting sheet, 15-pressure torsion spring, K ₁, K ₂-take key, -bulb.

Be with rotating disk (11), movable disk (12) (both is quadrangle among the figure) on the mandrel (7), rotating disk (11) is fixed with the position of mandrel (7), can not relatively rotate, rotating disk (11) is driven by pull handle (8) and rotates, rotating disk (11) drives mandrel (7) and rotates, the inner of time-delay clockwork spring (10) is fixed on the mandrel (7), the outer end is fixed on the movable disk (12), movable disk (12) can rotate around mandrel (7), and the rotation of mandrel (7) screws time-delay clockwork spring (10).Movable disk (12) cross section is " recessed " shape, has conducting sheet (13) that its surface is divided into conducting surface and insulating surfaces on the surface, and rotating disk (11) has conducting sheet (14) also its surface to be divided into conducting surface and insulating surfaces.As can be seen from Figure 5, two conducting circuits are arranged, need only one of them connection in two circuits, switch just is in conducting state, has only when two circuits all disconnect, and switch just is in off-state.The contact chip of having on the rotating disk among Fig. 1 (11) (6), conducting sheet (14), contact card (1) are formed first circuit of switch, route is a → b → c, the contact chip of having on the movable disk (12) (4), conducting sheet (13), contact card (3), lead (16) are formed second circuit of switch, route is a → d → e → f → c, the state of Fig. 1 is first circuit and second circuit state when all disconnecting, so switch is in not on-state.By backguy pulling pull handle (8), drive rotating disk (11) and rotate, contact card (1) contacts with conducting sheet (14), and first circuit is connected, and switch is in conducting state, and lamp is bright.Pull handle (8) is return under reduction torsion spring (5) effect, when rotating disk (11) rotates, rotating disk (11) screws by mandrel (7) clockwork spring (10) of will delaying time simultaneously, after pull handle (8) resetted, time-delay clockwork spring (10) discharged elastic energy and relaxes, and drove movable disk (12) and rotated, behind certain hour, contact card (3) contacts with conducting sheet (13), the also conducting of second circuit, and time-delay clockwork spring (10) has recovered original form.In the time will extinguishing lamp, pulling pull handle (8), rotating disk (11) rotates, contact card (1) separates with conducting sheet (14), first circuit disconnects, at this moment electric current is by second circuit a → d → e → f → c, make circuit still unimpeded, lamp is light yellow still, but the rotation of rotating disk (11) screws time-delay clockwork spring (10) by mandrel (7), and time-delay clockwork spring (10) begins to discharge elastic energy immediately, drives movable disk (12) and rotates, behind certain hour (as 30 seconds), conducting sheet (13) on the movable disk separates with contact card (3), and like this, second circuit also disconnects, thereby whole switch is in off-state, still get back to the state shown in Fig. 1, lamp extinguishes, and has so just realized the purpose that time-delay is turned off the light.For the ease of judging that switch is the state that is in the pass in the time-delay stage of turning off the light, can in the middle of circuit a → d → e → f → c, connect a forward diode or a resistance, when electric current flows through a → d → e → f → c circuit, because the effect of diode (or resistance), lamplight brightness is reduced, and people know that just switch has been in the state of pass like this.The effect of pressure torsion spring (15) is when pulling pull handle (8), pressure torsion spring (15) is turned round, make the torsion spring other end exert pressure for contact card (3), thereby it is motionless to make contact card (3) tightly suppress movable disk (12), like this, mandrel (7) rotation just can make time-delay clockwork spring (10) screw, pull handle (8) is when resetting, pressure extension spring (8) also resets, the pressure that imposes on contact card (3) also disappears, and movable disk (12) just is rotating to the release of elastic energy under time-delay clockwork spring (10) effect.

The utility model is simple in structure, and is easy to manufacture, and the time of time-delay be decided by the to delay time elastic constant of clockwork spring (10) can be made the product of different delay times as required.
