Description

Technical Field

[0001] The present invention relates to the technical field of image quality recognition, and in particular to a detachable image quality recognition detection device. Background Art

[0002] With the rapid development of social economy, image quality recognition and detection are becoming more and more important in the trend of information digitization. Image quality refers to people's subjective evaluation of the visual experience of an image. It is generally believed that image quality refers to the degree of error in the human visual system of the tested image relative to the standard image. Image quality can be divided into image fidelity and image intelligibility. Image fidelity describes the degree of deviation between the processed image and the original image; while image intelligibility indicates the degree to which people or machines can extract relevant feature information from the image.

[0003] However, the fixed frame structure on the existing image quality recognition and detection devices is mostly an integrated structure, and the staff cannot disassemble the entire fixed frame according to needs; and the fixing effect of the entire fixed frame is weak. Under a slight collision, a gap is easily generated between the fixed frame and the fixed platform, and the light in the gap has a great impact on the internal detection mechanism.

[0008] The fixed base, the fixed frame, the plug-in plate and the upper end plate are combined to form a closed space.

[0009] This basic solution designs a fixed base, a fixed frame, a plug-in plate, an upper end plate, a fixed connecting mechanism, and a stop fixing mechanism that are installed in combination. The fixed connecting mechanism and the stop fixing mechanism are used to limit the installation of the fixed frame and the upper end plate, respectively, to form a detachable combined shell. When repairing / repairing, it is only necessary to open the fixed connecting mechanism and toggle the stop fixing mechanism to release the tight installation between the various components for replacement or maintenance.

[0012] This solution designs vertically installed fixed pillars at the four end corners of the cabinet structure, which can limit the fixed frame to the corresponding installation area and reduce the difficulty of installation; the top of the side panel is extended outward to form an installation platform to install the fixed connection mechanism, so that the fixed connection mechanism abuts the bottom of the fixed frame, further improving the stability of the device.

[0013] In a further embodiment, the fixed connection mechanism comprises a matching plate, a rotating shaft, a first movable block, a second movable block, a pulling block and a clamping block; the clamping block is placed on the top surface of the mounting platform, and its top surface and outer side surface are embedded with the inner side surface of the second movable block, and the inner side surface is close to the fixed frame, and its top surface is also provided with a limiting groove embedded with the pulling block; the bottom of the matching plate is provided with a mounting hole that matches the rotating shaft, and the two matching plates are vertically fixed downward on the bottom surface of the mounting platform and fixedly connected to the mounting platform as positioning ends; one end of the first movable block extends horizontally inwardly and is movably connected to the matching plate through the rotating shaft, and the other end extends upwardly and is movably connected to one end of the second movable block; the other end of the second movable block extends horizontally inwardly and is parallel to the mounting platform, and a movable inner cavity is provided on it; the pulling block movably passes through the movable inner cavity and is embedded in the limiting groove to fix the clamping block, so that the clamping block abuts against the fixed frame as a limiting end;

At this time, the clamping block is released and the contact with the fixed frame is released, so that the fixed frame is disengaged from the limit and can be disassembled.

[0015] The scheme designs a movably plug-in pulling block, a second movable block, and a clamping block. The clamping block is positioned and limited by the pulling block and the second movable block, so that the clamping block abuts against the fixed frame, and the fixed frame is controlled to be in a fixed installation state; the pulling block is controlled to rise so that it is separated from the pulling block, and then the pulling block is pulled outward so that the first movable block and the second movable block are flipped outward along the rotating axis, so that the clamping block can be released and the abutment with the fixed frame can be released, and the fixed frame is then disengaged from the limit and can be disassembled, with a compact structure and simple operation.
