Description

Technical Field

[0001] The utility model relates to the technical field of two-dimensional code recognition, and more specifically, to a two-dimensional code device that can be recognized by both strong light and weak light. Background Art

[0002] A two-dimensional code is a black and white graphic that records data symbol information and is distributed in a plane (in two-dimensional direction) according to a certain rule using certain specific geometric figures. The code compilation cleverly uses the concepts of "0" and "1" bit streams that form the basis of the internal logic of a computer, and uses a number of geometric shapes corresponding to binary to represent textual numerical information. The code is automatically read by an image input device or a photoelectric scanning device to realize automatic information processing. When the existing two-dimensional code panel is recognized, if the external ambient light is strong, reflections are likely to occur. If the external ambient light is weak, it is difficult to clearly capture the two-dimensional code, resulting in strong light and weak light affecting the accuracy and speed of the scanning device in recognizing the two-dimensional code panel, thereby reducing the effectiveness of two-dimensional code recognition. Based on this, the utility model designs a two-dimensional code device that can be recognized by both strong light and weak light, so as to solve the above problems. Utility Model Content

[0003] The purpose of the utility model is to provide a two-dimensional code device that can be identified in both strong light and weak light, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a two-dimensional code device identifiable by both strong light and weak light, comprising a U-shaped carrier, a two-dimensional code panel and a light shield, the inner surface of the U-shaped carrier is provided with a middle groove, the two-dimensional code panel is adapted to the middle groove, two light strips are symmetrically and fixedly embedded on the inner side of the U-shaped carrier, a slider is slidably connected inside the middle groove, two springs are symmetrically and fixedly connected between the U-shaped carrier and the slider, the two-dimensional code panel contacts the opposite end faces of the slider, a positioning screw is threadedly connected between the U-shaped carrier and the two-dimensional code panel, the light shield is arranged on the U-shaped carrier, and two limit grooves are symmetrically provided on the top surface of the U-shaped carrier, a limit plug is fixedly connected to the bottom of the light shield at the corresponding position of the limit groove, and the limit plug is cooperatively plugged into the limit groove.

[0005] As a preferred technical solution of the utility model, a handle is fixedly installed on the upper end of the light-isolating cover, and the cross-sectional shape of the handle is an inverted L shape.

[0006] As a preferred technical solution of the present utility model, the top surface of the two-dimensional code panel is flush with the inner surface of the U-shaped carrier.

[0007] As a preferred technical solution of the utility model, the number of the positioning screws is two, and the positioning screws are symmetrically distributed.

[0008] As a preferred technical solution of the utility model, a countersunk hole is opened on the side of the U-shaped carrier, and the end cap of the positioning screw is located in the countersunk hole.

[0009] As a preferred technical solution of the utility model, the bottom end of the U-shaped carrier is symmetrically fixedly connected with a support foot, and the bottom surface of the support foot is fixedly installed with an anti-slip rubber pad.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model provides a U-shaped carrier, a light shield and a light strip. If the ambient light is weak, the light shield is lifted up on the U-shaped carrier by using a handle, and the light strip is turned on. The light strip can increase the brightness of light around the QR code panel, making it convenient for the scanning device to clearly capture the QR code. If the ambient light is normal, the light strip is turned off, and the scanning device can be used to identify the QR code panel. If the ambient light is strong, the limit plug is inserted into the limit groove so that the light shield is limitedly installed on the U-shaped carrier. The light shield can block the ambient light and effectively prevent reflection, thereby facilitating identification of strong light and weak light, so as to ensure the accuracy and speed of the scanning device in identifying the QR code panel, which is conducive to ensuring the effectiveness of QR code recognition.

[0012] 2. The utility model provides a slider, a spring and a positioning screw. If the two-dimensional code panel needs to be replaced, the two positioning screws are loosened, and the slider is driven by the spring to push the two-dimensional code panel out along the middle groove, so that the two-dimensional code panel can be taken out for replacement.

The inner surface of the U-shaped carrier 1 is provided with a middle groove 4, and the two-dimensional code panel 2 is adapted to the middle groove 4. Two light strips 5 are symmetrically fixedly embedded on the inner side of the U-shaped carrier 1. The light strips 5 can improve the light brightness around the two-dimensional code panel 2. A slider 401 is slidably connected inside the middle groove 4. The U-shaped carrier 1 and the slider 401 are symmetrically fixedly connected. There are two springs 402, the two-dimensional code panel 2 is in contact with the opposite end faces of the slider 401, a positioning screw 6 is threadedly connected between the U-shaped carrier 1 and the two-dimensional code panel 2, the light-shielding cover 3 is arranged on the U-shaped carrier 1, and two limiting grooves 101 are symmetrically provided on the top surface of the U-shaped carrier 1, and the bottom of the light-shielding cover 3 is fixedly connected to the limiting plug block 301 at the corresponding position of the limiting groove 101, and the limiting plug block 301 is cooperated and inserted in the limiting groove 101, so that the light-shielding cover 3 is convenient for limited installation and disassembly on the U-shaped carrier 1.

[0022] Among them, Figure 6 As shown, a handle 7 is fixedly mounted on the upper end of the light-isolating cover 3 , and the cross-sectional shape of the handle 7 is an inverted L-shape, so as to facilitate the upward extraction of the light-isolating cover 3 on the U-shaped carrier 1 .

[0023] Among them, Figure 2 As shown, the top surface of the two-dimensional code panel 2 is flush with the inner surface of the U-shaped carrier 1, ensuring the overall flatness of the two-dimensional code panel 2 and the U-shaped carrier 1.

[0024] Among them, Figure 4 and Figure 5 As shown, there are two positioning screws 6, which are symmetrically distributed to ensure the positioning and stability of the two-dimensional code panel 2 on the U-shaped carrier 1.

Use the scanning device to identify the two-dimensional code panel 2, so that both strong light and weak light can be identified, so as to ensure the accuracy and speed of the scanning device to identify the two-dimensional code panel. If the two-dimensional code panel 2 needs to be replaced, loosen the two positioning screws 6, use the spring 402 to drive the slider 401 to push the two-dimensional code panel 2 out along the middle groove 4, and the two-dimensional code panel 2 can be taken out for replacement.
