Description

Technical Field

[0001] This utility model relates to the field of image acquisition equipment technology, specifically a portable face image acquisition device. Background Technology

[0002] When collecting personnel information in various workplaces, it is often necessary to use facial image recognition equipment to collect and record facial information to prevent unauthorized personnel from entering the workplace later.

[0003] Some existing facial image recognition acquisition devices are used at a fixed height. However, since people have different heights, the only way to collect data is to adjust the angle of the camera on the facial image recognition acquisition device. However, arbitrarily adjusting the camera angle can easily lead to overexposure, which is quite inconvenient.

[0004] To address the aforementioned issues, this application provides a portable face image acquisition device. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a portable face image acquisition device to address the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a portable face image acquisition device, including a base, a housing connected to the top of the base, an adjustment mechanism provided inside the housing, the adjustment mechanism including a motor, a lead screw, a threaded sleeve, and a vertical rod, the motor being installed on the top of the base and located inside the housing, the top of the motor output shaft being connected to the bottom of the lead screw, the top of the lead screw being threadedly connected to the inside of the threaded sleeve, and the threaded sleeve being connected to the bottom of the vertical rod, the vertical rod penetrating the top of the housing and slidably connected to the housing, the top of the vertical rod being rotatably connected to a mounting block via a damping shaft, and the device body being installed on the right side of the mounting block.

[0007] Preferably, the inner wall of the housing has limit grooves on both the front and rear sides, and the outer wall of the vertical rod is connected to sliders on both the front and rear sides, with one end of the slider slidably connected inside the limit groove.

[0008] Preferably, a cover plate is hinged to the front of the housing, and the cover plate has heat dissipation holes.

[0009] Preferably, a light shield is connected to the right side of the mounting block, and the light shield is located on the top of the device body.

[0010] Preferably, the top of the housing has a through hole, and a baffle is provided inside the through hole. A fixing plate is connected to the left side of the inner wall of the housing, and a spring is connected between the fixing plate and the baffle. The size of the through hole is the same as the size of the upper surface of the light shield.

[0011] Preferably, the bottom of the baffle is connected to a limiting rod, the limiting rod passes through the fixing plate and is slidably connected to the fixing plate, and a spring is sleeved on the limiting rod.

[0012] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0013] 1. This portable face image acquisition device uses a motor to drive a lead screw to rotate. The lead screw, through a threaded sleeve, drives a vertical rod to move up and down. The vertical rod, through a mounting block, drives the device body to move up and down, thereby adjusting the height of the device and enabling it to acquire images of people of different heights.

[0014] 2. This portable face image acquisition device can be shielded from light by setting a light shield to avoid affecting image acquisition. Rotating the mounting block so that the device body faces left, and then starting the motor to store the device body inside the housing. When the mounting block moves down to the upper surface and coincides with the upper surface of the housing, the light shield presses the baffle to move down. At this time, the light shield moves into the through hole, thereby sealing the upper surface of the housing to prevent foreign objects from entering. The device is easy to store and carry.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" means two or more, unless otherwise explicitly specified.

[0023] like Figure 1-3As shown, this utility model provides a portable face image acquisition device, including a base 1, a housing 2 connected to the top of the base 1, an adjustment mechanism 4 inside the housing 2, the adjustment mechanism 4 including a motor 41, a lead screw 42, a threaded sleeve 43, and a vertical rod 44. The motor 41 is installed on the top of the base 1 and located inside the housing 2. The top of the output shaft of the motor 41 is connected to the bottom of the lead screw 42. The top of the lead screw 42 is threadedly connected to the inside of the threaded sleeve 43, and the threaded sleeve 43 is connected to the bottom of the vertical rod 44. The vertical rod 44 passes through the top of the housing 2 and is slidably connected to the housing 2. The top of the vertical rod 44 is rotatably connected to a mounting block 45 through a damping shaft. The right side of the mounting block 45 is equipped with a device body 46, which is an image acquisition device. Limiting grooves 48 are opened on the front and rear sides of the inner wall of the housing 2. Slider 47 is connected to the front and rear sides of the outer wall of the vertical rod 44, and one end of the slider 47 is slidably connected to the inside of the limiting groove 48. A cover plate 3 is hinged to the front of the housing 2, and heat dissipation holes 31 are opened on the cover plate 3.

[0024] Specifically, by starting the motor 41, the lead screw 42 is driven to rotate. The lead screw 42 drives the vertical rod 44 to move up and down through the threaded sleeve 43. The vertical rod 44 drives the equipment body 46 to move up and down through the mounting block 45, thereby adjusting the height of the equipment and enabling the equipment to capture images of people of different heights.
