Abstract
The utility model relates to a motor-driven door with a safety device, particularly a motor-driven door whose safety device can be immediately and automatically cut and close door action can be stopped when the human body or an object is touched in closing stroke. The utility model is characterized in that the hazardous area of the motor-driven door is provided with a brake band made of flexible materials, two interphase electric conduction copper sheets are arranged in the brake band to form a point touch switch, and an electromagnetic switch and a transformer connected with the electromagnetic switch are arranged. The positive and the negative wires of the electromagnetic switch are connected with a driving motor, and the positive and the negative wires of the transformer are connected with the two electric conduction copper sheets in the brake band.
Description
The utility model relates to a kind of electric door that has safety device, if when brushing up against human body or object, its safety device can be cut off the electricity supply automatically immediately and be stopped to close the door action in particularly a kind of electric door shutoff stroke.
The child is crushed or presss from both sides by electric door extremely, during this type of miserable accident what is heard is arranged, though this can blame the carelessness in adult's treatment, main cause is that still general electric door (for example electronic iron gate, electric rolling door) lacks effective safety device and causes.
The utility model lacks safety device at existing electric door, causes the shortcoming of unexpected injury easily, and purpose provides a kind of electric door that has safety device.
The strap of the brake made from soft material in the installing one of the hazardous area of electric door that is characterised in that of the present utility model, two alternate conductive copper sheets are housed in the strap of the brake and form and a little touch switch, and be provided with an electromagnetic switch and be attached thereto the transformer that connects, positive and negative line with electromagnetic switch connects drive motors, and with two conductive copper sheets in the positive negative wire connection strap of the brake of transformer.
Principle of the present utility model be when the strap of the brake in electric door hazardous area brush up against human body or object the time, two conductive copper sheets promptly contact and the inductive electromagnetic switch, and the action power dump of this electromagnetic switch of nationality and the action that stops to close the door, to prevent that human body or object from being injured, reach the purpose and the effect of safe handling.
Fig. 1 is a schematic configuration diagram of the present utility model.
Fig. 2 is a strap of the brake constructional drawing of the present utility model.
Further illustrate the utility model below in conjunction with accompanying drawing.
Structure of the present utility model comprises the strap of the brake 1, electromagnetic switch 2 and transformer 3.
The strap of the brake 1 is to form with soft plastic material (as P, V, C) or rubber material or other insulation materials manufacturing, this strap of the brake 1 is the hollow strip, be equiped with two identical strip conductive copper sheets 11 and 12 in it, two conductive copper sheets 11,12 a little touch switch because of middle elastomeric isolation forms, and this strap of the brake 1 can be installed in the hazardous area (hazardous area is meant the electric door root edge of upper and lower switching) of electric door 10 by any way.
Above-mentioned electromagnetic switch 2 and transformer 3 are connected, it is existing product, its installation site can be decided according to the particular case of electric door, can't influence the effect performance of safety device, power supply is connected with drive motors 4 through the positive and negative line 21 of electromagnetic switch 2, and be the roll-type electric wire through the positive and negative line 31 of transformer 3, be connected with two conductive copper sheets 11,12 in the lock curtain 1.
Aforementioned means is activated in the shutoff stroke of back in electric door 10, when any point of the strap of the brake of installing when the hazardous area of electric door 1 touches human body or object, constituting two conductive copper sheet 11,12 that touch switch in the strap of the brake 1 promptly contacts and inductive electromagnetic switch 2, action takes place and cuts off the electricity supply in this electromagnetic switch 2 immediately, the action of closing the door of electric door is stopped, and then the danger that injured of human body or object is removed.
The voltage of aforementioned two conduction steel discs 11,12 does not have injury because of become only 12 volts through transformer 3 transformations to human body, thereby is loaded on when brushing up against human body in the strap of the brake 1 in electric door 10 hazardous areas, does not have the danger of electric shock.
