Abstract
The invention relates to a rocking arm with signal output. The rocking arm comprises a front rocking arm, a front rocking arm shaft, a rear rocking arm, a rear rocking arm shaft, a supporting seat and a sensor, and is characterized in that the rocking arm is connected with the rear rocking arm by the front rocking arm shaft; the rear rocking arm is connected with the supporting seat by the rear rocking arm; the sensor is arranged on the rear rocking arm; and the position of the sensor on the rear rocking arm can be adjusted forward and backward. The rocking arm with signal output is simple in structure and convenient to use, and can be directly mounted on an ordinary door closer.
Description
Technical field
The present invention relates to the door closer field, specifically a kind of rocking arm of band signal output.
Background technology
Door closer is a hydraulic press of a upper spring-like, can door be shut automatically by discharging after the compression after door is opened, and the effect that resembles swinging door is arranged, and after can guaranteeing to be unlocked, is closed to accurately, timely initial position.The meaning of door closer not only is the door autoshutdown, can also protect doorframe and door body (steadily closing), the more important thing is that door closer has become a very important operating part of modern architecture intelligent management.Door closer mainly is used in commercial and the public building, but situation about using is at home also arranged.They have a lot of purposes, wherein topmost purposes be make the door close voluntarily, limit fire spread with mansion in ventilation.
The operating principle of door closer is: when opening the door, and the action of door body drivening rod, and travelling gear is rotated, drive the tooth bar plunger to right-hand movement.The process medi-spring that moves to right at plunger is compressed, and the hydraulic oil in the right chamber is pressurized also.The one way valve spheroid in plunger left side is opened under the effect of oil pressure, and the hydraulic oil in the right chamber flows in the left chamber through one way valve.After the process of opening the door was finished, because spring is compressed in opening process, the elastic potential energy of putting aside was released, and with the plunger thruster of turning left, band nutating gear and door closer connecting rod rotate, and door is closed.
The basic building block of door closer has supporting guide, travelling gear, back-moving spring, one way valve, tooth bar plunger, throttling valve core and housing, end cap, sealing ring and connecting rod.Door closer in the market seldom has belt sensor, particularly can induction door whether open or close the sensor of situation, confirm a lot of whether door closer works, particularly need to tend to door closer and monitoring system are used in the situation of the accurately folding of grasp door.
Summary of the invention
The present invention is directed to above technical problem, provide a kind of simple in structure, easy for installation, do not need to cooperate huge monitoring system, can accurately grasp the rocking arm of band signal output of the folding situation of door.
The present invention is achieved through the following technical solutions.
A kind of rocking arm of band signal output comprises front arm, front arm axle, rear arm, rear arm axle, bearing, sensor.It is characterized in that front arm is connected by the front arm axle with rear arm, rear arm is connected by the rear arm axle with bearing, and sensor setting is on rear arm.The position of sensor on rear arm can be regulated front and back.
During use, rotation on the front arm axle realizes the rotation of opening with closing of door by front arm and rear arm, the present invention is by arranging sensor at rear arm, when door is closed, angle between front arm and the rear arm diminishes, sensor is when sensing that the interval narrows down to predetermined distance between front arm and the sensor, sensor is output signal, this moment, show gate was closed condition, when door was opened, it is large that angle between front arm and the rear arm becomes, and sensor is when sensing that predetermined distance is expanded at the interval between front arm and the sensor, sensor is output signal, and be that show gate is opening this moment.In addition, can realize the control to sensor output signal by the front and back position of sensor on rear arm moved, thereby can realize the Real Time Monitoring of show gate unlatching size state.
The present invention is simple in structure, and is easy to use.Can directly install at common door closer.
Description of drawings
In the accompanying drawing, Fig. 1 is structural representation of the present invention, wherein:
1-front arm, 2-front arm axle, 3-rear arm, 4-rear arm axle, 5-bearing, 6-sensor.
Specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
A kind of rocking arm of band signal output comprises front arm 1, front arm axle 2, rear arm 3, rear arm axle 4, bearing 5, sensor 6.It is characterized in that front arm 1 is connected by front arm axle 2 with rear arm 3, rear arm 3 is connected by rear arm axle 4 with bearing 5, and sensor 6 is arranged on the rear arm 4.The position of sensor 6 on rear arm 4 can be regulated front and back.
During use, realize the rotation of opening with closing of door by front arm 1 and the rotation of rear arm 3 on front arm axle 2, the present invention is by arranging sensor 6 at rear arm 3, when door is closed, angle between front arm 1 and the rear arm 3 diminishes, sensor 6 is when sensing that the interval narrows down to predetermined distance between front arm 1 and the sensor 6, sensor 6 is output signal, this moment, show gate was closed condition, when door was opened, it is large that angle between front arm 1 and the rear arm 3 becomes, and sensor 6 is when sensing that predetermined distance is expanded at the interval between front arm 1 and the sensor 6, sensor 6 is output signal, and be that show gate is opening this moment.In addition, can realize the control to sensor 6 output signals by the front and back position of sensor 6 on rear arm 4 moved, thereby can realize the Real Time Monitoring of show gate unlatching size state.
The present invention is simple in structure, and is easy to use.Can directly install at common door closer.
