Description

A kind of telescopical electric apparatus control apparatus of coin-feed that is used for

Technical field

The utility model belongs to a kind of electric apparatus control apparatus, mainly as the telescopical electric apparatus control apparatus of coin-feed.Also can be used for simultaneously the control of similar products.。

Background technology

The coin-feed telescope is to supply tourist attractions such as skyscraper, scenic spot, seabeach to supply the visitor to view and admire scenery to use; Drop into the coin of appointment as the visitor after; Just can use telescope to watch the scenery that is invisible to the naked eye at a distance, be a kind of optical articles that extends the visual observation effect.

Coin-feed telescope electric apparatus control apparatus is depicted as example with Fig. 1,2, partly is made up of controller I, dimmer II, coin-freed arrangement III and power supply IV etc.Its primary structure: in the controller I; Circuit board 7 is fixed in the plastic casing 6 through screw 8; Inductive switch 1, dimmer II, coin-freed arrangement III are connected with plug 2,3,4 respectively, and plug inserts in the corresponding jack on the control circuit board 7, is connected to attaching plug 5 on the side of plastic casing 6.Its principle of work: when the visitor when the inlet input of coin-freed arrangement III is specified coin; After coin-freed arrangement detects this information, feed back signal to the controller I, send instruction by controller and make the work of dimmer II; In the time of appointment, the visitor can watch scenery at a distance through telescope.

For a long time, this control device can satisfy request for utilization basically, has brought into play positive role in practice.But aspect technical pattern, exist some irrational aspect: A, because the respective socket of the control circuit board 7 of controller I, the inductive means coin-freed arrangement III cavity in, electromagnetic valve components, dimmer II, coin-freed arrangement III, inductive switch 1 and control circuit board 7, plug and supporting socket etc.; All expose outside or unsealing; The entering or the etch of rainwater and steam during open-air the use cause short circuit, loose contact easily or burn; B, in the dimmer II, (see Fig. 3,4), stepper motor 10 is connected with gear 12, and gear shaft 11 1 ends pass bearing 9 and cooperate with gear 12, and anti-dazzling screen 16 is connected on the gear shaft 11 through screw 15.During stepper motor 10 work, driven gear 12 rotates, thereby anti-dazzling screen 16 is rotated; After the signal of controller I imported secondary circuit plate 13 into, anti-dazzling screen 16 inwardly was brought together into the position of dotted line in the direction of arrows, and this moment, telescopical light path was unobstructed; Human eye can be watched scenery at a distance through telescope, and anti-dazzling screen 16 is outwards opened by the diagram dotted line position after the time of program setting, in the groove of the sensing chip 17 reeve inductive switches 14 on the anti-dazzling screen; After inductive switch 14 is sensed sensing chip 17; Control anti-dazzling screen 16 is parked in shown position, and this moment, telescopical light path was cut off, and human eye just can not be observed through telescope.The dimmer II that assembles is installed in telescope inside (between object lens and the eyepiece), and friction force strengthens when low temperature, the easy clamping stagnation of gear set; Add any breaking down in inductive switch 14 and the secondary circuit plate 13; Anti-dazzling screen can not reliably be opened, close up, and influence is watched, when breaking down; Be difficult to the failure judgement reason, can only a whole set ofly change; C, because the power consumption of coin-freed arrangement III is bigger; Be about 75mA during standby, need the lithium battery of special DC12V 5000mAh customized to supply power as the power supply IV, this lithium battery costs an arm and a leg; And whole coin-feed telescope product is when marketing; Railway and Air Branch do not allow to transport lithium battery, can only walk highway, bring inconvenience to transportation.

In view of there are the problems referred to above in former electric apparatus control apparatus, fault is frequent when having brought the coin-feed telescope to use, poor stability, and defectives such as cost of manufacture height must be improved.

Summary of the invention

The technical problem underlying that the utility model will solve is: according to the defective of the telescopical electric apparatus control apparatus existence of existing coin-feed; Make improvements; The important spare part of controller, coin-freed arrangement is sealed and the corrosion protection design, the structure of dimmer is designed again.Fundamentally overcome the defective of failure-frequency height, poor stability.Reach the quality level of comprehensive raising stabilization control device, reduce production costs, adapt to batch production requirement.

The main technical schemes of the utility model is: a, sealing controller architecture, and circuit board is fixed tightly in in the plastic casing through screw, holder is installed on the plastic casing again; Compress with bung flange behind the O-ring seal on the pad, after cable penetrated from holder, O-ring seal compressed with bung flange on the pad; Load onto sealing gasket at the plastic casing left end; Buckle cover plate and tighten up with screw, the display screen and the keytop of plastic casing stick film, all sealings in the whole plastic casing; B, joint sealing behind the plug insertion socket, compress O-ring seal with guard shield; C, rotation dimmer structure, stepper motor is screwed on Connection Block, and the axle of stepper motor is connected through screw with contiguous block, and anti-dazzling screen is connected on the contiguous block with screw; D, mechanical structure of coin feeding apparatus, the inner physical construction that adopts aluminum alloy materials to produce fully is only at mechanical coin-freed arrangement Go outThe contact switch of a sealing is installed at the mouth place; E, power supply adopt the dry cell of No. 2 1.5V of two joints.

The utility model proves through practical application: the frame mode of sealing, dimmer and coin-freed arrangement through improving electrical equipment, simplified the control device structure, and reduced cost, improved the telescopical performance quality of coin-feed effectively.
