具体实施方式detailed description
实施例1Example 1
如图1-3所示，一种红外激光自动感应防夹锁，包括外壳1和上盖2，所述的上盖2通过螺丝与外壳1固连；所述的外壳1内安装有隔板7，所述的隔板7通过螺丝与外壳1内的支架固连；所述的外壳1内，位于隔板7的下方安装有控制电路板8和电池9；所述的电池9通过线路与控制电路板8相连；所述的外壳1侧面开设有锁头开口12，所述的隔板7上安装有锁头4，且所述的锁头4的一端穿过锁头开口12后位于外壳1外；控制电路板8包括机械闭锁机构和电控闭锁机构，机械闭锁机构连接并带动锁头做伸缩动作，电控闭锁机构是通过电磁铁来改变杠杆支点进行控制锁头伸出缩入的变支点杠杆结构，因而锁头4是活动的，受控制电路板8。所述的外壳1上还分别开设有红外接收器安装孔3和红外激光二极管安装孔10，所述的红外接收器安装孔3和红外激光二极管安装孔10上分别安装有红外接收器5和红外激光二极管6；所述的红外接收器和红外激光二极管分别通过线路与控制电路板相连。所述的上盖2上开设有4个螺丝孔11；所述的4个螺丝孔11均匀分布在上盖2的两侧，且两两平行开设；所述的4个螺丝孔11上分别安装有螺丝，且所述的上盖2通过螺丝与门框固连，可将红外激光自动感应防夹锁与门框固连。As shown in Figure 1-3, an infrared laser automatic induction anti-pinch lock includes a casing 1 and an upper cover 2, the upper cover 2 is fixedly connected to the casing 1 by screws; a partition is installed inside the casing 1 7. The partition 7 is fixedly connected with the bracket in the casing 1 by screws; in the casing 1, a control circuit board 8 and a battery 9 are installed below the partition 7; the battery 9 is connected to the The control circuit board 8 is connected; the side of the shell 1 is provided with a lock opening 12, the lock 4 is installed on the partition 7, and one end of the lock 4 passes through the lock opening 12 and is located in the shell 1. The control circuit board 8 includes a mechanical locking mechanism and an electronically controlled locking mechanism. The mechanical locking mechanism is connected and drives the lock head to perform telescopic movements. The electronically controlled locking mechanism uses an electromagnet to change the fulcrum of the lever to control the extension and retraction of the lock head. Change fulcrum lever structure, thereby lock head 4 is movable, controlled circuit board 8. The housing 1 is also provided with an infrared receiver mounting hole 3 and an infrared laser diode mounting hole 10 respectively, and an infrared receiver 5 and an infrared laser diode mounting hole 10 are installed on the infrared receiver mounting hole 3 and the infrared laser diode mounting hole 10 respectively. Laser diode 6; the infrared receiver and the infrared laser diode are respectively connected to the control circuit board through lines. The upper cover 2 is provided with four screw holes 11; the four screw holes 11 are evenly distributed on both sides of the upper cover 2, and opened in parallel; the four screw holes 11 are respectively installed There are screws, and the upper cover 2 is fixedly connected to the door frame through screws, so that the infrared laser automatic induction anti-pinch lock can be fixedly connected to the door frame.
将本实施例通过螺丝穿过4个螺丝孔11后，将红外激光自动感应防夹锁安装在门框上，如图4所示；在正常情况下，红外激光二极管6发出的光线在设置的一定距离内投射到地面，并通过地面正常反射到红外接收器5，当关门时，手置于门缝处，挡住了部分红外激光二极管6发出的光线，此时红外接收器5所接收到的光量将减少。掌握这种减少后，控制电路板8接收到此信息，因而启动锁头的线路被接通，即电控开锁机构被启动，再者能够带动锁头做伸缩动作的机械开锁机构开始工作，即由电磁铁来改变杠杆支点进行控制，使锁头4伸出，阻止门被关上，从而防止手被门夹住的危险。After the present embodiment is passed through 4 screw holes 11 by screws, the infrared laser automatic induction anti-pinch lock is installed on the door frame, as shown in Figure 4; It is projected to the ground within a distance, and is normally reflected to the infrared receiver 5 through the ground. When the door is closed, the hand is placed at the crack of the door, blocking part of the light emitted by the infrared laser diode 6. At this time, the amount of light received by the infrared receiver 5 is will decrease. After mastering this reduction, the control circuit board 8 receives this information, thus the circuit for starting the lock head is connected, that is, the electronically controlled unlocking mechanism is started, and the mechanical unlocking mechanism that can drive the lock head to do telescopic action starts to work, that is, The fulcrum of the lever is controlled by the electromagnet, so that the lock head 4 is stretched out to prevent the door from being closed, thereby preventing the danger of the hand being caught by the door.
