It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Example

[0026] Infrared linkage alarm protection device, please refer to Figure 1 、 Figure 2 and Figure 3 , including two transmission mechanisms 1, one side of each of the two transmission mechanisms 1 is provided with a detection mechanism 5 for infrared detection, one side of each of the two transmission mechanisms 1 is provided with a docking mechanism 4 for installing the detection mechanism 5, and the interior of each of the two transmission mechanisms 1 is provided with a displacement mechanism 3 for driving the two docking mechanisms 4 to move up and down, and the upper ends of the two transmission mechanisms 1 are provided with an adjustment mechanism 2 for driving the transmission mechanism 1 to operate. The close cooperation between the displacement mechanism 3 and the transmission mechanism 1 makes the position adjustment of the detection mechanism 5 flexible and accurate, providing a good platform foundation for subsequent infrared detection work. The design of the adjustment mechanism 2 simplifies the operation process, so that the user only needs to By rotating the adjustment knob 208, the position of the detection mechanism 5 can be precisely adjusted, which greatly improves the convenience of use. The flexible combination of the docking mechanism 4 and the detection mechanism 5 not only facilitates the installation and maintenance of the detection equipment, but also makes the entire detection system more adaptable. At the same time, the rapid adjustment function of the detection mechanism 5 further improves the efficiency and accuracy of the detection work. Through the precise control of the transmission mechanism 1 and the displacement mechanism 3 by the adjustment mechanism 2, the flexible adjustment of the position of the detection mechanism 5 is achieved, thereby meeting the needs of different detection scenarios. This design not only improves the efficiency and accuracy of the detection work, but also greatly improves the user experience.

[0027] like Figure 4 and Figure 6As shown, the transmission mechanism 1 includes a base plate 101, and columns 102 are installed on both sides of the upper end of the base plate 101. The tops of the two columns 102 are fixedly connected to the top of the top plate 103. The center of the bottom plate 101 and the top plate 103 are fixedly sleeved with first bearings 104, and the inner rings of the two first bearings 104 are fixedly sleeved with screw rods 105. The two columns 102 close to each other are arranged with multiple guide grooves 106. The displacement mechanism 3 includes a slider 301, and the slider 301 is threadedly sleeved on the outside of the screw rod 105. The two sides of the slider 301 away from each other are arranged in a rectangular shape with multiple bolt holes 302. The other two sides of the slider 301 away from each other are arranged and fixedly connected with multiple guide rails 303. The multiple guide rails 303 are respectively slidably sleeved in the multiple guide grooves 106. The transmission mechanism 1 serves as the core support of the entire system. The supporting structure constructs a stable frame through the base plate 101, the column 102 and the top plate 103, and the displacement mechanism 3 cleverly utilizes this frame. Through the threaded connection between the screw rod 105 and the slider 301, and the sliding cooperation between the guide rail 303 on the slider 301 and the guide groove 106 on the column 102, the precise movement of the slider 301 in the vertical direction is achieved. This design not only ensures the smoothness of the displacement, but also makes the displacement adjustment simple and precise through the rotation control of the screw rod 105. When the position of the detection mechanism 5 needs to be adjusted, the screw rod 105 is driven to rotate by the adjustment mechanism 2, and the rotation of the screw rod 105 is converted into the linear motion of the slider 301, thereby driving the docking mechanism 4 and the detection mechanism 5 installed thereon to move up and down. This transmission method not only ensures the accuracy of the displacement, but also facilitates simple control.

[0028] like Figure 5As shown, the adjustment mechanism 2 includes a protective shell 201, and a second bearing 202 is fixedly sleeved on one side of the protective shell 201 near the upper and lower ends, and a third bearing 203 is fixedly sleeved on both sides of the protective shell 201 near the other end. The inner rings of the two second bearings 202 are fixedly sleeved with a transmission rod 204, and the bottom end of the transmission rod 204 is fixedly connected to the top of the screw rod 105. A worm gear 205 is fixedly sleeved at the center of the outer side of the transmission rod 204, and a driving rod 206 is fixedly sleeved on the inner rings of the two third bearings 203. A worm 207 is fixedly sleeved at the center of the outer side of the driving rod 206. The worm 207 and the worm wheel 205 are helically geared. An adjustment knob 208 is fixedly connected to one side of the driving rod 206. The adjustment mechanism 2 is a key part of the control system. Through the worm wheel 205 and the worm 20 7 Transmission principle, which realizes the rotation control of the screw 105 inside the transmission mechanism 1. The second bearing 202 and the third bearing 203 in the protective shell 201 support the transmission rod 204 and the drive rod 206 respectively, making the entire transmission process more stable and reliable. The helical gear transmission of the worm wheel 205 and the worm 207 not only has a large transmission ratio, but also can realize the self-locking function to prevent reverse rotation when no external force is applied. By rotating the adjustment knob 208, the drive rod 206 and the worm 207 are driven to rotate. The rotation of the worm 207 then drives the worm wheel 205 and the transmission rod 204 connected thereto to rotate. The bottom end of the transmission rod 204 is fixedly connected to the top of the screw 105, so the screw 105 also rotates accordingly, and finally drives the detection mechanism 5 to move up and down through the displacement mechanism 3.

[0029] like Figure 7 、 Figure 8 and Figure 9As shown, the docking mechanism 4 includes two mounting plates 401, and the two mounting plates 401 are respectively arranged on both sides of the slider 301, and a docking plate 402 is fixedly connected to one side of the two mounting plates 401. A plurality of fastening bolts 403 are arranged in a rectangular shape inside the two mounting plates 401, and the assembly ends of the plurality of fastening bolts 403 respectively pass through one side of the two mounting plates 401 and pass into the interior of the plurality of bolt holes 302. The center of one side of the docking plate 402 is fixedly connected with ear pieces 404 at the upper and lower ends. The two detection mechanisms 5 both include protective covers 501, and the two protective covers 501 are respectively rotatably connected to the middle of the two ear pieces 404 at one side and the two ear pieces 404 at the other side. A plurality of infrared receivers 502 and infrared transmitters 503 are arranged and fixedly connected at the upper and lower ends of the two protective covers 501. The center of the two protective covers 501 is fixedly sleeved with There is a buzzer 504, and a glass cover 505 is fixedly connected to the upper and lower ends of the center of the side where the two protective covers 501 are close to each other. The docking mechanism 4 serves as the installation carrier of the detection mechanism 5. Through the mutual cooperation of the mounting plate 401, the docking plate 402 and the fastening bolts 403, the detection mechanism 5 is quickly installed and disassembled. At the same time, the design of the ear piece 404 provides a reliable connection point for the detection mechanism 5, ensuring its stability during operation. The protective cover 501 of the detection mechanism 5 is connected to the docking plate 402 through the ear piece 404, so that the detection mechanism 5 can move with the movement of the docking mechanism 4. The infrared receiver 502 and the infrared transmitter 503 inside the protective cover 501 cooperate with each other to complete infrared detection of the target object. When an abnormal situation is detected, the buzzer 504 will sound an alarm to alert the operator.

[0030] Working principle: The system consists of five parts: transmission mechanism 1, adjustment mechanism 2, displacement mechanism 3, docking mechanism 4 and detection mechanism 5. The transmission mechanism 1 builds a stable framework to provide support for the entire system. The adjustment mechanism 2, as the core of the control system, realizes precise rotation control of the lead screw 105 inside the transmission mechanism 1 through the transmission principle of worm gear 205 and worm 207. When the adjustment knob 208 is rotated, the driving rod 206 and worm 207 rotate accordingly, thereby driving the worm gear 205 and the transmission rod 204 to rotate, and finally driving the lead screw 105 to rotate. The rotation of the lead screw 105 is converted into linear motion of the slider 301 through the displacement mechanism 3. The guide rail 303 on the slider 301 is closely matched with the guide groove 106 on the column 102 to ensure the smooth movement of the slider 301 in the vertical direction. This design not only ensures the accuracy of displacement, but also facilitates the realization of automatic control. As the block 301 moves up and down, the docking mechanism 4 and the detection mechanism 5 installed thereon also move accordingly. The docking mechanism 4 cooperates with the mounting plate 401, the docking plate 402 and the fastening bolt 403 to achieve rapid installation and disassembly of the detection mechanism 5. At the same time, the design of the ear piece 404 provides a reliable connection point for the detection mechanism 5, ensuring its stability during operation. The protective cover 501 of the detection mechanism 5 is equipped with an infrared receiver 502 and an infrared transmitter 503, which cooperate with each other to complete the infrared detection of the target object. When an abnormality is detected, the buzzer 504 will immediately sound an alarm to remind the operator to pay attention. The entire system achieves flexible and precise adjustment of the position of the detection mechanism 5 through close cooperation and collaborative work between the various mechanisms, providing a good platform foundation for subsequent infrared detection work and greatly improving the efficiency and accuracy of the detection work.
