Description

Technical Field

[0001] This utility model relates to the field of people detection technology, and in particular to a people number detection device that is easy to install. Background Technology

[0002] Tourist attractions, factories, and other places with large numbers of people often need to count the flow of people at the gate. There are many existing mechanical barrier counting devices. When people pass through, the barrier needs to be pushed to rotate. After the people pass through, another barrier stops at the gate, and so on, thus achieving the purpose of counting the number of people.

[0003] However, existing personnel number detection devices require workers to use multiple sets of bolts and nuts to fix them in place during use, and multiple bolts need to be removed during maintenance. The operation process is cumbersome, making the existing personnel number detection devices inconvenient to install. Therefore, an easy-to-install personnel number detection device is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the problems existing in the background technology, this utility model proposes a personnel quantity detection device that is easy to install.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a personnel quantity detection device that is easy to install, comprising a mounting base and a personnel counter, wherein the personnel counter is slidably mounted on the mounting base; a mounting groove is provided on the front side of the mounting base, and a connecting slider is slidably mounted inside the mounting groove, the connecting slider being fixedly connected to the personnel counter; U-shaped connecting rods are slidably mounted on both sides of the connecting slider, and multiple limiting grooves are evenly provided on both sides of the mounting groove, one end of each U-shaped connecting rod is respectively inserted into the limiting groove, and a lever is fixedly mounted on the other end of each U-shaped connecting rod, and a return spring is fixedly connected between the lever and the outer wall of the connecting slider.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0017] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a personnel quantity detection device that is easy to install, including a mounting base 1 and a personnel counter 2, wherein the personnel counter 2 is slidably mounted on the mounting base 1. Assembly plates 10 are fixedly installed on both sides of the mounting base 1, and the mounting base 1 is fixed in the installation position by bolts on the assembly plates 10. The mounting base 1 is firmly fixed by the assembly plates 10 and bolts, providing a stable installation foundation for the entire device.

[0019] Furthermore, a mounting groove 3 is provided on the front side of the mounting base 1, and a connecting slider 4 is slidably mounted inside the mounting groove 3. The connecting slider 4 is fixedly connected to the people counter 2. The four corners of the connecting slider 4 are all rounded chamfered to facilitate insertion into the mounting groove 3. The rounded chamfered design of the connecting slider 4 facilitates its smooth sliding into the mounting groove 3, simplifying the installation and alignment process.

[0020] The connecting slider 4 consists of upper and lower parts joined together. Guide grooves 9 are provided on both sides of the joining position of the connecting slider 4, and U-shaped connecting rods 5 are slidably installed inside the guide grooves 9. U-shaped connecting rods 5 are slidably installed on both sides of the connecting slider 4. Multiple limiting grooves 6 are evenly provided on both sides of the mounting groove 3. One end of each U-shaped connecting rod 5 is inserted into the limiting groove 6 on both sides. The guide grooves 9 provide a precise sliding track for the U-shaped connecting rods 5, ensuring accurate insertion into the limiting grooves 6 of different heights, thus realizing the height adjustment function.

[0021] Both ends of the U-shaped connecting rods 5 on both sides are fixedly equipped with levers 7, and return springs 8 are fixedly connected between the levers 7 and the outer wall of the connecting slider 4. The return springs 8 are sleeved on the outside of the U-shaped connecting rods 5, with one end of the return spring 8 fixedly connected to the lever 7 and the other end fixedly connected to the outer wall of the connecting slider 4. The return springs 8 provide automatic rebound force, allowing the U-shaped connecting rods 5 to reliably engage in the limiting grooves 6, ensuring the stability of the device after installation. At the same time, the levers 7 are designed for easy manual operation.

[0022] The people counter 2 is equipped with an infrared sensor 11 on its bottom. Since the human body has a certain temperature and emits infrared radiation with a center wavelength of 9-10 μm, any sensor sensitive to this wavelength can be used as an infrared sensor for detecting people. In other words, when infrared radiation encounters the detection element, the surface temperature of the element changes, resulting in an electrical charge. This charge is extracted as an electrical signal, allowing for the detection of the infrared radiation. The infrared sensor 11 can effectively detect specific wavelengths of infrared radiation emitted by the human body and convert the detected signal into an electrical signal, achieving non-contact personnel detection.

[0023] As customers pass through the gate, the people counter 2 receives the data and transmits it to a simplified PC via an interface circuit. The PC then sends the people count results as a file to the main computer via the network. The results from each gate are then aggregated and displayed in real time. This achieves centralized data processing and remote real-time monitoring.

[0024] During installation, the people counter 2 is slid into the mounting groove 3 on the mounting base 1 via the connecting slider 4. Simultaneously, the levers 7 on both sides are squeezed, causing the U-shaped connecting rods 5 on both sides to move closer together. This causes the return springs 8 on both sides to contract, allowing the connecting slider 4 to smoothly slide into the mounting groove 3. When the U-shaped connecting rod 5 moves downward to the corresponding limiting groove 6 inside the mounting groove 3, the levers 7 are released. The return springs 8 then cause the U-shaped connecting rod 5 to slide into the limiting groove 6, completing the installation. Height adjustment can be achieved by connecting the U-shaped connecting rod 5 with multiple longitudinal limiting grooves 6. The entire operation is simple and quick, requiring no tools, thus improving the efficiency of installation and debugging.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
