Abstract
The utility model relates to an automatic-door safety device; a safety air bag is arranged on an automatic door; a motor drives the automatic door to move; a rubber pipe is connected with the air cavity of the safety air bag; a control mechanism controls the motor to work, and is characterized in that the control mechanism comprises an air-pressure detection device that is connected with the rubber pipe; the air-pressure detection device is connected with a wireless signal transmitting device; the wireless electric signal transmitting device controls the motor to work. Because the air-pressure detection device, the wireless electric signal transmitting device and the wireless signal receiving device are adopted to control the motor to work, the detection device is connected with the motor without a conducting wire, so that the operation of the safety device is safer.
Description
Technical field:
The utility model relates to a kind of automatic door safety device.
Background technology:
At present, various automatic doors have been widely used in occasions such as warehouse, garage, machine room.Existing automatic door is not generally established safety guard, makes automatic door extruding security incident happen occasionally.Be head it off, Chinese patent has just proposed a kind of " rolling-gate airbag safety device " for No. 02216582.7.This technical scheme automatic door safety device comprises: microswitch is fixed in the casing, is connected with control cabinet by lead; Film and box house are sealed to air cavity by hold-down ring, and air cavity is communicated with the rubber tracheae; The rubber tracheae other end seals by plug.The outer side center fixed-site of film is hit sheet, hits between the contact of sheet and microswitch and leaves minim gap, and the rubber air pipe sleeve has flexible jacket.It can improve the security performance of automatic door, reduces the generation of extruding security incident.But it has the following disadvantages:
1, because microswitch is connected with controlled motor by lead, and motor and microswitch distance are far away, makes that the connection lead is long.For the automatic garage door that motor also moves, being provided with of this connection lead can be made the danger of touching lead or breaking lead at automatic door in moving process, brought inconvenience to use.
2, realize controlling machine operation because frame for movements such as sheet and microswitch are hit in employing, frame for movement generally can't be adjusted and be set, and makes above-mentioned airbag safety device be easy to misoperation in the course of the work, and functional reliability is undesirable.
3, because airbag safety device directly is loaded on the bottom girder of below such as electric rolling, when rubber tracheae pressurized, microswitch is just controlled motor is quit work.Because the common planeness in installation place of automatic door is not very desirable at present, makes that the automatic door sealing performance of said structure is undesirable.
Summary of the invention:
The purpose of this utility model is: a kind of reliable operation, sealing performance ideal, automatic door safety device easy for installation are provided.
The utility model is achieved through the following technical solutions:
A kind of automatic door safety device, air bag is loaded on the automatic door, the action of driven by motor automatic door, rubber tube links to each other with the air cavity of air bag, controlling organization control machine operation; It is characterized in that: described controlling organization comprises: the pressure test device that is connected with rubber tube, pressure test device is connected with radio signal launcher, radio signal receiving apparatus control machine operation.
Advantage of the present utility model is: because the utility model adopts pressure test device, radio signal launcher and radio signal receiving apparatus to control machine operation, between checkout gear and motor, need not to be connected, make that the utility model work is safer by lead.Because adopt pressure test device, pressure test device can be adjusted and set the critical point of machine operation, the probability that it can effectively reduce misoperation makes that the utility model work is more reliable.
In the utility model, the air cavity periphery of described air bag is provided with the aliform bluff piece.When the aliform bluff piece can make the installation place planeness of automatic door undesirable, automatic door also had the better seal performance.
In the utility model, the air cavity periphery of described air bag is provided with brace, and the brace top is provided with lug boss, and the hard underseal bar that is connected with automatic door is provided with the cavity that matches with lug boss.It is more convenient that it can make air bag be connected with automatic door, and connect reliable.
In the utility model, described radio signal receiving apparatus is connected with function self check buzzer and alarm.
Description of drawings:
Fig. 1 is the utility model embodiment 1 structural representation.
Fig. 2 is the utility model embodiment 1 air bag and automatic door junction generalized section.
The specific embodiment:
As shown in Figure 1: the automatic door safety device of present embodiment comprises: air bag 1 is loaded on the automatic door 2, the action of driven by motor automatic door, and rubber tube 3 links to each other with the air cavity 4 of air bag 1, controlling organization control machine operation.Controlling organization comprises: the pressure test device 5 that is connected with rubber tube 3, pressure test device 5 is connected with radio signal launcher 6,8 work of radio signal receiving apparatus 7 control motors.Described radio signal receiving apparatus is connected with function self check buzzer 9 and alarm 10.
The course of work of present embodiment is as follows: when air bag is run into obstruction, the air bag pressurized, and pressure is reached pressure test device by rubber tube, through the pressure test device detection control signal is transmitted into radio signal receiving apparatus by radio signal launcher, thus the control machine operation.
Owing to adopt pressure test device, radio signal launcher and radio signal receiving apparatus to control machine operation, between checkout gear and controlled motor, need not to be connected by lead, make that the work of automatic door safety device is safer.Because adopt pressure test device, pressure test device can be adjusted and set the critical point of machine operation, it can effectively reduce the probability of misoperation.
As shown in Figure 2: air cavity 4 peripheries of air bag are provided with aliform bluff piece 11.The air cavity periphery of air bag is provided with brace 12, and the brace top is provided with lug boss 13, and the hard underseal bar 14 that is connected with automatic door 2 is provided with the cavity that matches with lug boss.When the aliform bluff piece can make the installation place planeness of automatic door undesirable, automatic door also had the better seal performance.It is more convenient that brace and hard underseal bar can make air bag be connected with automatic door.
