Abstract
The utility model discloses a ventilating device for a safety door, two parts of a guard plate 1 with an insulation interlayer are respectively connected with racks 2 and 3; a safety railing 4 can penetrate through the interlayer of the guard plate 1; the racks 2 and 3 and a gear wheel 5 are connected; the guard plate 1, a safety railing 4, the racks 2 and 3 and the gear wheel 5 are all arranged in a safety door leaf. The utility model has the advantages of insulation, strong safety, convenient operation and goodly style.
Description
The utility model relates to the security door ventilation installation.
Existing security door ventilation installation kind is a lot, mostly adopts turnover plate type, single pull-type, door in door formula, its shortcoming be antitheft and heat-insulating property poor, inconvenient operation, not attractive in appearance.
The purpose of this utility model is the deficiency that solves existing security door ventilation installation, and a kind of antitheft and strong, easy to operate, moulded security door ventilation installation attractive in appearance of the living energy of insulation promptly is provided.
For reaching this purpose, the technical solution of the utility model is as follows: 1, a kind of security door ventilation installation, comprise ventilation opening 6, it is characterized in that: have the backplate 1 that is incubated interlayer and form by upper and lower two halves, anti-theft guardrail 4 passes the interlayer of backplate 1, and gear 5 is connected with tooth bar 2,3, and tooth bar 2 is connected with the first half of backplate 1, tooth bar 3 is connected with the latter half of backplate 1, and backplate 1, anti-theft guardrail 4, tooth bar 2 and 3, gear 5 all are built in the antitheft door leaf.
Described gear 5 is connected electric driver 7, and drive unit 7 is driven by motor 8.
Described gear 5 is connected with the motor 8 by remote control circuit control.
After adopting technique scheme, because backplate of the present utility model 1 adopts quality steel plate to make interlayer, and is provided with anti-theft guardrail 4, and backplate 1 and anti-theft guardrail 4 all be built in the antitheft door leaf, thus be incubated and theftproof performance strong; Adopt gear 5 and tooth bar 2,3 because of transmission device of the present utility model again, reliable transmission, and the power of drive unit 7 can derive from the 6V dc-battery, and also can be unworthy of the manual folding of battery according to consumers' opinions, also can as electric door, adopt telecontrol engineering, so it is folding freely, easy to operate, flexible; In addition, of the present utility model moulded elegant in appearance.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is drive unit 7 control principle figure of the present utility model.
Fig. 3 is a remote control circuit theory diagram of the present utility model.
Fig. 4 is a remote control circuit schematic diagram of the present utility model.
Structure of the present utility model as shown in Figure 1, having the backplate 1 that is incubated interlayer is made up of upper and lower two halves, anti-theft guardrail 4 passes the interlayer of backplate 1, gear 5 is connected with tooth bar 2,3, tooth bar 2 is connected with the first half of backplate 1, tooth bar 3 is connected with the latter half of backplate 1, and backplate 1, anti-theft guardrail 4, tooth bar 2 and 3, gear 5 all are built in the antitheft door leaf.Wherein, under the gearing of gear 5 and tooth bar 2,3, the two halves up and down of backplate 1 can be done and split involutory straight line parallel motion, but the tracks of the not only antitheft also double as of anti-theft guardrail 4 backplate 1.When the two halves of backplate 1 was split to antitheft door leaf, ventilation opening 6 exposed, and involutory when tight when the two halves of backplate 1, ventilation opening 6 is sealed by backplate 1.
Backplate 1 can be manual in the utility model, also can be electronic, and can as electric door, adopt remote controller control.
When manual, draw back (or drawing) arbitrary half part backplate 1, the tooth bar 2 (or 3) that is connected of part backplate 1 can drive another tooth bars 3 (or 2) by gear 5 therewith, thereby draw back (or drawing) in addition half part backplate 1, two parts backplate 1 is done along anti-theft guardrail 4 split involutory straight line parallel and move.
When electronic, gear 5 is connected with drive unit 7, the control principle figure of drive unit 7 as shown in Figure 2, drive circuit is: the 6V dc-battery is by changeover switch K
1-1, K
2-1, K
1-2, K
2-2Link to each other with motor 8.Press changeover switch, can control turning to of motor, thereby drive the gear 5 link to each other with motor 8, gear 5 drives tooth bars 2 and 3, thereby the two parts that drive backplate 1 are done and split involutory straight line parallel and move.The 6V dc-battery can charge, and charging circuit is: the 220V civil power is formed whole current circuit rectification through transformer B with by D1-D4, again through the series arm voltage stabilizing of diode D5 and resistance R, then output is connected to plug JK after the rectification.Be connected to socket CK at 6V dc-battery two ends, plug JK is linked to each other with socket CK, can charge the 6V dc-battery.Drive unit 7 also is built in the antitheft door leaf during making, and charging circuit can connect and be built in the antitheft door leaf with drive unit 7, only leaves the interface that connects the 220V power supply on security door, does not influence the attractive in appearance of integral body.
When remote control, the motor 8 that gear 5 connects is controlled by remote control circuit.The remote control circuit theory diagram as shown in Figure 3, the remote control circuit schematic diagram is opening and closing of available remote controller control ventilation installation as shown in Figure 4 like this.
Transmission device adopts nylon gear, tooth bar in the sample of the present utility model, the light and reliable transmission of selection, and backplate adopts quality steel plate to make interlayer, and anti-theft guardrail adopts four six fens thick stainless steel tubes, and power adopts 6 volts of dc-batteries when electronic.Through on probation, can reach the purpose of this utility model fully, effect is splendid.
