Abstract
The invention relates to a adjustable grate element, comprising: at least one control display device, fixed shell and rotary emitter or receiver element in the fixed shell, wherein the control display device is set at the pivot of the emitter or receiver element.
Description
Technical field
The present invention relates to a kind of adjustable grating (light barrier also makes the light hurdle) element, it comprises: at least one controls display device, stationary housing and rotatable transmitter or receiver element in stationary housing.
Background technology
The grating that comprises this optical grating element specifically is used in combination with the garage door control device, to allow the automatic control that garage door drives or to satisfy security functions.
About this point, grating generally includes two optical grating elements: light barrier transmitter, the light beam of its emission grating; Grating receiver, it receives from the light barrier transmitter emitted light beams.About this point, two optical grating elements must be aimed at mutually, to guarantee the operation of grating no problem.For this reason, the transmitter of each optical grating element or receiver element can rotate in stationary housing.When this adjusting of carrying out optical grating element, since light beam less than+/-5 ° little optics opening angle, cause light barrier transmitter very accurately to be aligned on the grating receiver or grating receiver very accurately is aligned on the light barrier transmitter, therefore in fact often go wrong.Yet, owing to can stop the reflection of not expecting (for example reflection on door or floor covering), thereby these little opening angles are favourable.Therefore, trending towards opening angle with grating is chosen as even is lower than above-mentioned+/-5 °.In addition, because the used infrared light of grating is sightless, and because hull shape makes optical axis also can not recognize usually, so also can other problem occur aspect the adjusting of optical grating element.
Therefore, be provided with the control display, so that help optical grating element adjusting and with the relevant aligning of rotatable transmitter or receiver element in stationary housing, described control display device sends the signal of grating operation, and the correct adjusting of optical grating element can be shown by described control display device.
, can go wrong about this point, that is, the stationary housing owing to around rotatable transmitter or receiver element causes only can picking out the control display device that is connected in transmitter or receiver element difficultly.But other of control display device arranged again may be very expensive and/or complicated.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of adjustable light barrier member, wherein can easily see the control display device, and this optical grating element has simple structure.
According to the present invention, can realize this purpose by adjustable light barrier element according to claim 1.Has at least one control display device, stationary housing and in stationary housing in the adjustable light barrier element of rotatable transmitter or receiver element, according to the present invention, the control display device is arranged on the pivot place of transmitter or receiver element this.Therefore can see this control display device easily from the outside, and still can be connected in the electron device that is arranged in transmitter or the receiver element in simple mode.
In another favourable mode, the control display device is arranged on the end of pivot, and this pivot passes the opening in the stationary housing.Opening in the stationary housing is always in the mode of the pivot that holds transmitter or receiver element and occur, thereby the control display device that is arranged on the place, pivot end of passing this opening is located in the outside of stationary housing, therefore is provided with in the mode that can see easily.
Thus, the control display device is advantageously provided the place, two ends at pivot.Thus, can easily check the operation of grating from the both sides of stationary housing.
The pivot of transmitter or receiver element advantageously is fixedly connected on transmitter or receiver element.Thus, the control display device that is arranged on the pivot place also can be connected to the electron device that is arranged in transmitter or receiver element, and this connection can be owing to the rotation or the mobile influence that is subjected to mechanical stress of transmitter or receiver element.Therefore, reduce wearing and tearing, and can save the expensive and/or complicated flexible connection between transmitter or receiver element and the control display device.
Advantageously, the pivot of transmitter or receiver element rotatably is coupling in stationary housing.This realizes in particularly advantageous mode, and promptly two openings that are arranged in the sidewall that stationary housing is oppositely arranged are passed in the end of pivot.Therefore, pivot can transmitter or receiver element in stationary housing rotate, and allows the simple adjustment of grating thus.
Advantageously, pivot has axially open at least one place, end, and the control display device is arranged in this axially open.Control display device thus and only protrude in outside the stationary housing slightly, and still can be recognized at an easy rate.
In another favourable mode, pivot comprises hollow cylinder.Electrical connector both between control display device and control display device and the electron device in transmitter or receiver element can be arranged on the inside of this hollow cylinder.The layout that this allows the simple especially of control display device and does not have wearing and tearing.
In another favourable mode, the control display device comprises control lamp or LED.Can show whether grating works by the illumination of control lamp or LED, thus can be with the correct adjusting of simple mode evaluation of transmitter or receiver element.
Description of drawings
Set forth the present invention in more detail now with reference to embodiment.
About this point, Fig. 1 shows the skeleton view of the embodiment of the invention.
Embodiment
As can be seen from Fig. 1, adjustable light barrier element according to the present invention comprises transmitter or the receiver element 2 that is rotatably installed in the stationary housing 1.The control display device is arranged on the two ends place of pivot 3, and this pivot passes two openings on the sidepiece of being oppositely arranged of stationary housing 1, and is fixedly connected to transmitter or receiver element 2.Show by this control display device whether grating correctly works.For the light barrier transmitter of grating is aimed at grating receiver, perhaps vice versa, and then, can make transmitter or receiver element 2 in stationary housing, rotate in order to regulate grating, show that up to the control display device correct work of grating and optical grating element are correctly regulated.Then, transmitter or receiver element can be fixed in the correct position by fixture 4.About this point, fixture 4 comprises screw rod, in the groove in this screw rod insertion stationary housing, and can be screwed in transmitter or the receiver element, thereby can transmitter or receiver element be fixed in the correct adjusting position by tensioning threaded rods 4.
Because control display device (this control display device can comprise for example control lamp or LED) is arranged in the end regions of pivot 3, so can see this control display device easily.In order further to improve observability and to allow the control display device to be arranged on two sidepieces of stationary housing, the control display device also is arranged in the end regions of the pivot on another sidepiece (not shown here) of housing.About this point, this control display device protrudes in outside the stationary housing slightly, thereby can see the control display device that each is single in 180 ° angular range.This control display device is fixedly connected to transmitter or receiver element 2, thereby this control display device can not be subjected to mechanical stress owing to the rotation of transmitter or receiver element 2.
