Description

Technical Field

[0001] This utility model relates to the field of image test cards, and in particular to a video surveillance test card fixing device. Background Technology

[0002] The core function of the fixing device for the video surveillance test card is to ensure that the test card remains stable and accurately positioned within the field of view of the surveillance camera, so that the video surveillance test card can correspond to the image captured by the surveillance camera.

[0003] However, existing fixing devices are limited in their single fixing method and lack versatility. Different devices are required for different testing environments, such as suction cup fixing, track fixing, and support fixing. The more devices there are, the more the video surveillance test card needs to be disassembled and reinstalled, which not only damages the video surveillance test card but also reduces work efficiency. Utility Model Content

The surface of the fixing body is provided with an embedding groove, and a pressing mechanism is installed on the edge of the embedding groove. The base includes a fixed seat and a movable seat installed on the rear side of the fixed seat. The movable seat and the fixed seat are detachably connected. The movable seat is designed with an L-shaped structure. A connector is installed on the side of the movable seat near the fixing body. A plug is provided at the rear of the fixing body. The plug and the connector are installed vertically. A recessed cavity is provided on the vertical surface of the movable seat, and a first fixing bolt is installed inside the recessed cavity.

[0007] Preferably, the fixing seat is an L-shaped structure, and the horizontal plate is attached to the surface of the fixing seat to form a cuboid. The bottom of the fixing seat and the top of the support seat are fixedly connected. The fixing seat includes: a limiting hole located at the rear of the fixing seat, which is corresponding to the shape and position of the protruding column; and a second fixing bolt that passes through the front of the fixing seat and is threaded to the front of the horizontal plate.

[0008] Preferably, the plug-in has an inverted U-shaped groove structure, and the connector is fixed to the outside of the plug-in in a wrapping manner.

[0009] Preferably, the rear surface of the fixing body is provided with an installation block, the plug-in is provided with a connecting groove on the side facing the fixing body, a third fixing bolt is installed on the top of the plug-in, and the installation block is fixed to the inside of the connecting groove by the third fixing bolt.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] In the attached diagram, all identical reference numerals refer to the same components.

[0018] In the first embodiment, as Figure 1-4 As shown, this utility model provides a video surveillance test card fixing device, including a support base 1 that provides overall structural support. The support base 1 fixes the upper base 2 and the fixing body 3. The fixing body 3 mainly fixes the video surveillance test card based on the embedding groove 31 and the pressing mechanism 4. However, the existing conventional fixing devices have poor versatility. Such fixing mechanisms are generally movable and cannot be transformed into other states, such as a permanent wall-mounted structure. Therefore, the base 2 is designed with a detachable fixed seat 21 and a movable seat 22. The fixed seat 21 is mainly fixed to the upper part of the support base 1, and after being spliced ​​with the movable seat 22, it completes the fixing function for the fixing body 3. When the movable seat 22 needs to be fixed to the wall, the second fixing bolt 212 at the front of the fixed seat 21 can be removed first, the horizontal plate 223 and the fixed seat 21 can be removed, and the protruding column 225 and the limit vertical separation can be separated. Then, the first fixing bolt 222 can be inserted into the recessed cavity 221 at the vertical plate 226 of the movable seat 22, and the first fixing bolt 222 can be rotated and fixed to the prefabricated part with screw holes on the wall, or directly fixed to the opening in the wooden wall.

[0019] Furthermore, the fixing body 3 can be vertically inserted downwards into the connecting piece 5 of the vertical plate 226 via the rear plug-in piece 6. That is, during the above process, the fixing body 3 can be disassembled first to handle the installation of the movable seat 22 separately. Figure 2 and3 As shown.

[0020] Furthermore, during installation, the bottom of the fixed body 3 can be embedded into the horizontal groove 224, forming a frame-like stable structure when fixed to the wall with the movable seat 22, preventing the fixed body 3 from tilting. The C-shaped structure of the vertical plate 226 also makes it easy for the head of the first fixing bolt 222 to be stored in the recessed cavity 221, so as not to obstruct the insertion position of the connector 6.

[0021] Furthermore, in order to allow the overall equipment to fit the fixed body 3 of different sizes, an installation block 32 is designed at the rear of the fixed body 3. The connecting groove 61 on the upper part of the connector 6 and the installation block 32 are disassembled and installed by the third fixing bolt 62, so that the connector 6 can be installed on the fixed body 3 of different sizes to fix video surveillance test cards of different sizes.

[0022] The structure is simple and can be installed in different environments according to actual requirements. For example, the movable seat 22 can be installed on the fixed seat 21 for mobile use. The movable seat 22 can also be installed on the wall or other movable rails. The movable seat 22 has an L-shaped structure, which can keep the fixed seat 3 in a vertical position when installed together with the fixed seat 3, reducing the error caused during subsequent video surveillance testing.

[0023] In another embodiment, such as Figure 1 and 5 As shown, the clamping mechanism 4 includes an adjusting threaded rod 42 and a pressing plate 41, so that after the adjusting threaded rod 42 is rotated, the pressing plate 41 is fixed to the edge of the video surveillance test card. The video surveillance test card is mainly inserted from the insertion port 33 at the top of the fixing body 3 into the inner embedding groove 31. After insertion, the top is limited to prevent it from falling directly to the outside. The left and right edges are fixed by the pressing plate 41 in conjunction with the embedding groove 31, so as to facilitate the replacement of different video surveillance test cards.

[0024] Furthermore, to reduce damage to the edge of the video surveillance test card caused by the pressing plate 41, a compression spring 43 and a pressure plate 44 are designed. As the pressing plate 41 approaches the embedding groove 31, the compression spring 43 pushes the pressure plate 44 to approach the video surveillance test card until it is in contact with the video surveillance test card. After applying pressure again, the compression spring 43 increases the pressure on the pressure plate 44 and absorbs the larger pressure formed by the pressing plate 41. This allows the pressure on the video surveillance test card to be adjusted according to the elastic modulus of the compression spring 43, realizing a more concrete and precise adjustment of the force.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
