Description
Technical field
The utility model is related to rolling screen door technical field, more particularly to roller shutter door limiting device.
Background technology
Electric rolling door is used widely in places such as StoreFront, garages, and electric rolling door lifting is driven by door roller, is rolled up
Door machine is general to drive spool turns by transmission mechanism, and reel, which drives, is wrapped in the door curtain on reel along downslide on door curtain guide rail
Move to realize switch gate.It can be automatically stopped when door curtain is elevated to precalculated position, the function is completed by roller shutter door limiting device,
Existing roller shutter door limiting device is general to drive screw rod rotation by the gear being connected with door roller transmission mechanism, makes determining on screw rod
Position device axially moves to touch travel switch, and travel switch sends electric signal, so as to stop door roller operation.Due to existing
Roller shutter door limiting device uses mechanical transmission-type, and structure is more complicated, secondly, and mechanical fatigue and travel switch internal electrical contact are burnt
Erosion can cause travel switch failure, rolling screen door is not stopped at precalculated position, cause to damage.
Utility model content
The utility model provides a kind of reliable roller shutter door limiting device, and existing stopping means can be overcome easily mechanical
Fatigue and the shortcoming of the easy ablation of electric contact.
The utility model is achieved through the following technical solutions：
Roller shutter door limiting device, including permanent-magnet steel, tongue tube and controller；The permanent-magnet steel is located at rolling screen door door curtain
Bottom girder end；The tongue tube includes upper limit tongue tube and lower limit tongue tube；The upper limit tongue tube is located at door curtain enabling back door
The corresponding door curtain guide rail position side of curtain bottom girder stop position, lower limit tongue tube is located at door curtain guide rail bottom side；The dry spring
Pipe and controller electrical connection.
When closing rolling screen door, door curtain drops to door curtain guide rail bottom along door curtain guide rail, located at the permanent of door curtain bottom girder end
Magnet steel is close to lower limit tongue tube, and lower limit tongue tube just sends electric signal to controller, and controller, which is connected to after electric signal, controls rolling door
Machine is stopped, and door curtain stops declining；Similarly, when opening rolling screen door, door curtain rises along door curtain guide rail, when located at door curtain bottom girder end
When the permanent-magnet steel in portion is close to upper limit tongue tube, upper limit tongue tube just sends electric signal to controller, and controller is connected to electric signal
Control door roller is stopped afterwards, and door curtain stops rising.Adjust position of the upper limit tongue tube in door curtain guide rail side, so that it may adjust
What door curtain opened the door is automatically stopped position.
Further, the door curtain bottom girder two ends are equipped with permanent-magnet steel, and the door curtain guide rail side of door opening both sides is equipped with
Tongue tube and lower limit tongue tube are limited, upper limit tongue tube and lower limit tongue tube are electrically connected with the controller.The tongue tube of door opening both sides
Play mutual insurance, when the tongue tube of side breaks down, the tongue tube of opposite side remains to play a role.
Further, the door curtain guide rail side above the upper limit tongue tube is provided with preventing colliding with top tongue tube, and the preventing colliding with top is done
Reed pipe and controller electrical connection.Preventing colliding with top tongue tube plays safety effect to upper limit tongue tube, when upper limit tongue tube breaks down,
Preventing colliding with top tongue tube can prevent door curtain from continuing up damage rolling screen door.
The beneficial effects of the utility model are：Spacing, energy is carried out to rolling screen door using permanent-magnet steel, tongue tube and controller
Overcome the shortcoming of the easy mechanical fatigue of existing stopping means and the easy ablation of electric contact, it is reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is circuit diagram of the present utility model.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
As depicted in figs. 1 and 2, embodiment of the present utility model, roller shutter door limiting device, including permanent-magnet steel 1, tongue tube
With controller 2；The permanent-magnet steel 1 is located at the end of bottom girder 4 of rolling screen door door curtain 3；The tongue tube includes the He of upper limit tongue tube 5
Lower limit tongue tube 6；The upper limit tongue tube 5 corresponding position of door curtain guide rail 7 of the stop position of door curtain bottom girder 4 after door curtain enabling
Side, lower limit tongue tube 6 is located at the bottom side of door curtain guide rail 7；The tongue tube and controller 2 are electrically connected.
When closing rolling screen door, door curtain 3 drops to the bottom of door curtain guide rail 7 along door curtain guide rail 7, located at the end of door curtain bottom girder 4
Permanent-magnet steel 1 is close to lower limit tongue tube 6, and lower limit tongue tube 6 just sends electric signal to controller 2, and controller 2 is connected to after electric signal
Control door roller 8 is stopped, and door curtain 3 stops declining；Similarly, when opening rolling screen door, door curtain 3 rises along door curtain guide rail 7, when setting
When the permanent-magnet steel 1 of the end of door curtain bottom girder 4 is close to upper limit tongue tube 5, upper limit tongue tube 5 just sends electric signal to controller 2,
Controller 2, which is connected to after electric signal, controls door roller 8 to be stopped, and door curtain 3 stops rising.Adjustment upper limit tongue tube 5 is led in door curtain
The position of the side of rail 7, so that it may which adjust the enabling of door curtain 3 is automatically stopped position.
In the present embodiment, the two ends of door curtain bottom girder 4 are equipped with permanent-magnet steel 1, and the side of door curtain guide rail 7 of door opening both sides is equal
Provided with upper limit tongue tube 5 and lower limit tongue tube 6, upper limit tongue tube 5 and lower limit tongue tube 6 are electrically connected with controller 2.Door opening two
The tongue tube of side plays mutual insurance, and when the tongue tube of side breaks down, the tongue tube of opposite side remains to play a role.
In the present embodiment, the side of door curtain guide rail 7 of the top of upper limit tongue tube 5 is provided with preventing colliding with top tongue tube 9, described anti-
Rush to summit tongue tube 9 and controller 2 is electrically connected.Preventing colliding with top tongue tube 9 is to 5 safety effects of upper limit tongue tube, when upper limit tongue tube 5
When breaking down, preventing colliding with top tongue tube 9 can prevent door curtain 3 from continuing up damage rolling screen door.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
