Description
Technical field
The present invention relates to a kind of infrared laser and automatically respond to the anti-pinch lock, belong to infrared laser induction technology field.
Background technology
The children's safety problem is social discussion focus always, as the children of disadvantaged group, no matter is indoor, or outdoor, and safety problem all exists everywhere.Even accompanying of the head of a family arranged, still can't avoid some hard to guard against danger.For example children's hand is pressed from both sides this safety problem by door, in existing product, has hiding crack between a door and its frame to reach the product of finger effect, child door folder etc. is also arranged, but it is attractive in appearance, installs, and anti-pinch effect etc. all have problems.
Summary of the invention
The object of the invention is to provide a kind of infrared laser automatically to respond to the anti-pinch lock, has overcome deficiency of the prior art, utilizes the infrared laser induction technology, reaches the automatic spring tapered end, stops door to be shut, thereby prevents the danger that hand is clamped by door.
In order to achieve the above object, technical scheme of the present invention is:
A kind of infrared laser is responded to the anti-pinch lock automatically, comprises shell and upper cover, and described upper cover is connected by screw and shell; In described shell, dividing plate is installed, described dividing plate is connected by the support in screw and shell; In described shell, the below that is positioned at dividing plate is equipped with control circuit board and battery; Described battery is connected with control circuit board by circuit; Described shell side offers the tapered end opening, on described dividing plate, tapered end is installed, and an end of described tapered end is positioned at outside shell after passing the tapered end opening; On described shell, also offer respectively infrared remote receiver installing hole and infra-red laser diode installing hole, be separately installed with infrared remote receiver and infra-red laser diode on described infrared remote receiver installing hole and infra-red laser diode installing hole; Described infrared remote receiver is connected with control circuit board by circuit respectively with infra-red laser diode.
On described, cover and offer 4 screw holes; Described 4 screw holes are evenly distributed on the both sides of upper cover, and parallel offering in twos; On described 4 screw holes, be separately installed with screw, and described upper cover is connected by screw and doorframe.
The invention has the beneficial effects as follows: of the present inventionly provide a kind of infrared laser automatically to respond to anti-pinch lock, utilized the infrared laser induction technology, reached the automatic spring tapered end, stoped door to be shut, thereby prevent the danger that hand is clamped by door.A side of section is installed with infra-red laser diode (being light projector) and infrared remote receiver side by side within it, and control circuit board is equipped with in the bottom of opposite side, battery, and on it, be fixed with a dividing plate, be connected with the shell medial cradle by screw, finally above dividing plate, be provided with tapered end.When hand is placed in crack between a door and its frame, block laser, whole circuit namely is switched on, and the tapered end automatic spring prevents from being shut, and this process is convenient and swift, and successful greatly reduces the potential safety hazard that children's hand is pressed from both sides by door.

The specific embodiment
?
As Figure 1-3, a kind of infrared laser is responded to the anti-pinch lock automatically, comprises shell 1 and upper cover 2, and described upper cover 2 is connected by screw and shell 1; In described shell 1, dividing plate 7 is installed, described dividing plate 7 is connected by the support in screw and shell 1; In described shell 1, the below that is positioned at dividing plate 7 is equipped with control circuit board 8 and battery 9; Described battery 9 is connected with control circuit board 8 by circuit; Described shell 1 side opening is provided with tapered end opening 12, on described dividing plate 7, tapered end 4 is installed, and an end of described tapered end 4 is positioned at outside shell 1 after passing tapered end opening 12; Control circuit board 8 comprises mechanical lock and automatically controlled blocking mechanism, mechanical lock connects and drives tapered end does expanding-contracting action, automatically controlled blocking mechanism is by electromagnet, to change balance pivot to control the floating rod structure that tapered end stretches out retraction, thereby tapered end 4 is movable, controlled circuit board 8.On described shell 1, also offer respectively infrared remote receiver installing hole 3 and infra-red laser diode installing hole 10, on described infrared remote receiver installing hole 3 and infra-red laser diode installing hole 10, be separately installed with infrared remote receiver 5 and infra-red laser diode 6; Described infrared remote receiver is connected with control circuit board by circuit respectively with infra-red laser diode.On described upper cover 2, offer 4 screw holes 11; Described 4 screw holes 11 are evenly distributed on the both sides of upper cover 2, and parallel offering in twos; On described 4 screw holes 11, be separately installed with screw, and described upper cover 2 is connected by screw and doorframe, infrared laser can be responded to automatically to the anti-pinch lock and be connected with doorframe.
After the present embodiment is passed to 4 screw holes 11 by screw, infrared laser is responded to the anti-pinch lock automatically and be arranged on doorframe, as shown in Figure 4; Under normal circumstances, the light that infra-red laser diode 6 sends projects ground in the certain distance arranged, and pass through the ground regular reflection to infrared remote receiver 5, when at closing time, hand is placed in the crack between a door and its frame place, blocked the light that part infra-red laser diode 6 sends, now the received light quantity of infrared remote receiver 5 will reduce.After grasping this minimizing, control circuit board 8 receives this information, thereby the circuit that starts tapered end is switched on, be that automatically controlled unlocking mechanism is activated, moreover can drive tapered end and do the mechanical unlocking mechanism of expanding-contracting action and start working, namely by electromagnet, change balance pivot and control, tapered end 4 is stretched out, stop door to be shut, thereby prevent the danger that hand is clamped by door.
A kind of infrared laser of the present embodiment is responded to the anti-pinch lock automatically, utilizes the infrared laser induction technology, reaches the automatic spring tapered end, stops door to be shut, thereby prevents the danger that hand is clamped by door.A side of section is installed with infra-red laser diode (being light projector) and infrared remote receiver side by side within it, and control circuit board is equipped with in the bottom of opposite side, battery, and on it, be fixed with a dividing plate, be connected with the shell medial cradle by screw, finally above dividing plate, be provided with tapered end.When hand is placed in crack between a door and its frame, block laser, whole circuit namely is switched on, and the tapered end automatic spring prevents from being shut, and this process is convenient and swift, and successful greatly reduces the potential safety hazard that children's hand is pressed from both sides by door.
