Abstract

The utility model discloses an electric rolling door. A switch K is arranged on the rolling door. An insulating handle capable of toggling the switch K is linked with a lock bar of the rolling door. The switch K is connected in series with a power circuit of a motor of the rolling door; a lock core of the rolling door is provided with two pieces of key contact plates. An insulating strip is lined at the fixed point of the contact plate, and one of the contact plates is connected with an indicator light D on the rolling door through a conducting wire. The rolling door is also provided with an electrical source battery E of the indicator light D. The utility model can prevent the damage of the rolling door because of the false start of the motor of the rolling door.

Description

The electric rolling gate door

The utility model relates to a kind of electric rolling gate door.

The electric rolling gate door is widely used in occasions such as shop, bank, office building; at present; electric rolling gate door of the prior art does not generally all have the electric motor starting protective device; so in use; when door is when locking, when the key of perhaps unblanking does not reach, if the error starting motor; just be easy to rolling-gate is drawn bad, thereby cause unnecessary loss.Therefore existing electric rolling gate door is still not ideal enough in use.

The purpose of this utility model is: provide a kind of and can prevent rolling-gate motor error starting and damage the electric rolling gate door of rolling-gate, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it is equipped with 1～2 K switch on existing motored rolling-gate (1), the locking bar (2) of the insulation handle of toggle switch K and rolling-gate (1) is connected, K switch is connected on the electric electromechanics source circuit of rolling-gate (1), at the lock core place of rolling-gate (1) two key contacts (3) are housed, the fixed point of contact (3) is lined with insulating trip (4), and wherein there is a contact (3) to be connected with indicator lamp D on being contained in rolling-gate (1), the power-supply battery E of indicator lamp D also is housed on rolling-gate (1) by lead.

Owing to adopted technique scheme, the utility model is compared with existing electric rolling gate door, has the advantage that can prevent rolling-gate motor error starting and damage rolling-gate.During use, earlier key is injected in the lockhole, key contacts with two contacts (3), thereby indicator lamp D is communicated with battery E, indicator lamp D is bright, during key, makes locking bar (2) action, and drive K switch action, after key was all reached the position, K switch was just closed fully, at this moment key is extracted from lockhole, indicator lamp D extinguishes, and can open the motor DJ of rolling-gate like this; When rolling-gate was closed and lock, because locking bar (2) is opened K switch, thereby the power supply of motor was cut off, even press the start button AN of motor, motor can not worked yet, thereby has prevented that the situation of damaging rolling-gate because of misoperation from taking place.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the connection diagram of the utility model locking bar and K switch;

Accompanying drawing 3 is that the utility model contact, indicator lamp and battery are installed connection diagram;

Accompanying drawing 4 is the utility model circuit for controlling motor schematic diagram.

Embodiment of the present utility model: motored rolling-gate (1) preferably adopts stainless steel cast rolling-gate, during making, locking bar (2) in rolling-gate (1) locates to load onto a K switch, if two locking bars are just installed two K switch, with on each K switch can toggle switch K the insulation handle be connected with the locking bar (2) of rolling-gate (1) respectively, and K switch is connected on the electric electromechanics source circuit of rolling-gate (1), load onto two key contacts (3) at the lock core place of rolling-gate (1), and on the fixed point pad of contact (3) insulating trip (4), a contact (3) wherein is connected with indicator lamp D on being contained in rolling-gate (1) by lead, on rolling-gate (1), installs the power-supply battery E of indicator lamp D.

Claims

1, a kind of electric rolling gate door, it comprises motored rolling-gate (1), it is characterized in that: 1～2 K switch is housed on rolling-gate (1), the locking bar (2) of the insulation handle of toggle switch K and rolling-gate (1) is connected, K switch is connected on the electric electromechanics source circuit of rolling-gate (1), at the lock core place of rolling-gate (1) two key contacts (3) are housed, the fixed point of contact (3) is lined with insulating trip (4), and wherein there is a contact (3) to be connected with indicator lamp D on being contained in rolling-gate (1), the power-supply battery E of indicator lamp D also is housed on rolling-gate (1) by lead.
