Abstract
The utility model relates to a power saving safety lock, belonging to an energy-saving and safe electric appliance. The utility model is characterized in that a power saving safety card which is tied with the key to a house door is used as interlocking, the energy-saving control can be realized by a magnetic coupling switch. When people lock a door and leave a room with the key being carried, the magnetic coupling switch can automatically cut off an indoor main power supply. Thus, the power can not be consumed without people being in the room, and the wear or ageing of the equipment can not happen. In particular, the bad damage of the electrical equipment and the electrical fire accident caused by operation with failures in the presence of nobody can be prevented. The practicability of the utility model lies in low cost and convenient installation for buildings.
Description
The utility model is the design about a kind of new economize on electricity safety lock.
In factory floor, research laboratory, dwelling house and hotel guest-room, existing power supply switch often generation personnel withdraw from a room and forget and turn off power supply, cause personnel not at the scene under the situation, the electric equipment long-play.With but abnormal failure occurs and can not get timely processing, will cause substantial equipment to damage or form fire incident.
The utility model the economize on electricity safety lock of opinion, comprise the ferromagnetic coupling switch enclosure that can be installed on the inboard wall control panel of door, and lying in of carrying of discrepancy personnel, and has the interlocking card that interlocking triggers function with key.
The design's purpose is, utilizes anyone must carry these characteristics of key when withdrawing from a room, and the interlocking card is connect with key system as a kind of jewelry.Going out leaves away must be with key, also takes away the interlocking card simultaneously, and ferromagnetic like this coupling box switch will disconnect full chamber power supply.When personnel turn the key in the lock enter house after, put the triggering window place that the interlocking card that connects with key system is done the ferromagnetic coupling switch, then ferromagnetic attraction force is powered through interlocking card transmission closing contact and to indoor equipment.
Fig. 1 is the profile of economize on electricity safety lock.Fig. 2 is an A-A cross section view among Fig. 1, to show the structure of inner magnetic circuit.Fig. 3 is a B-B cross section view among Fig. 1, to show the structure and the action situation of electrical contact.
The name of each several part is called in Fig. 1 to 3: 1-plastic box body, 2-interlocking card, 3-metal tethers, 4-key, 5-permanent magnet, 6-pole shoe, the non-magnetic cover plate of 7-, 8-slide block, 9-static electrical contact, the movable electrical contact of 10-, 11-box body back shroud, 12-moving contact hold-down screw, 13-fixed contact hold-down screw.
As shown in Figure 1, box body is a rectangle.Hole on four jiaos is an installing hole.Can be on wall or control panel by screw.Positive rectangular channel cave of protruding the position is called the triggering window.When interlocking card is positioned over this when triggering window, in box body under the suction of permanent magnet by being adsorbed on the box body tightly.
In Fig. 2, permanent magnet 5 adopts the annular magnetic steel of loud speaker.It and steel pole shoe 6 have been formed the ferromagnetic coupling magnetic circuit together.The effect of non magnetic cover plate 7 is that the pole shoe air gap is closed, and enters between the air gap seam to prevent foreign matter.Because it adopts namagnetic substance (copper or aluminium or plastics), so can not make magnetic circuit square road.Interlocking card 2 is the steel sheet, under the attraction of magnetic force, to the pressure of slide block 8 generations to the box body inner chamber.
Shown in Figure 3, slide block 8 is spacing as warp-wise with the hole wall that forms when the box body injection moulding, and can slide vertically at this.Slide block 8 is controlled by interlocking card 2 and moving contact 10 in axial position.Interlocking card 2 is depressed slide block 8, and slide block 8 gives moving contact 10 with pressure and make it contact power connection in the control room with fixed contact 9 to the box body inner slide.
Take away interlocking card 2 when personnel withdraw from a room, slide block 8 outwards slides under moving contact 10 reed elastic force effects, and the contact disconnects indoor power supply.
The concrete best approach that realizes of economize on electricity safety lock described in the utility model is:
(1) adopt homemade seriation loud speaker annular magnetic steel to make permanent magnet.
(2) box body can be used the Shooting Technique manufacturing, is beneficial to batch process.
(3) the design contact is a two point form, can be directly used in the control of single phase alternating current power supply.When being used for load, then only need adding the commercially available contactor of one-level in addition and get final product than big or three phase mains control.
Claims (1)
- The utility model is a kind of new economize on electricity safety lock, it is characterized in that in box body with bakelite or plastic production, form magnetic circuit with annular permanent-magnet steel and pole shoe, have the steel sheet of good magnetic property to close pintle hook lock even with door key system;A pair of electrical contact is installed in the box body inboard, by screw on box body, slide block is subjected to the effect of moving contact and interlocking card and is that track slides with the hole on the box wall between the two, and realizes break-make control to the contact by its location status.
