Description

Technical Field

[0001] This utility model relates to the field of media data annotation and recognition technology, and in particular to a media data annotation and recognition device that is easy to disassemble. Background Technology

[0002] A media data annotation and recognition device is a processing system composed of numerous electrical components mounted on a circuit board. These components include a microprocessor, memory, sensors, signal processing units, and communication interfaces. Together, they form a relay processing system for media data annotation and recognition. Its main function is to receive, process, and annotate image, text, video, and audio information input into the system, store the processed information, and display it through connected peripheral display devices. The circuit board housing these electrical components is typically fixed to the inner wall of a control cabinet and then connected to an external control platform via connecting cables.

[0003] However, in the existing technology, the circuit boards used in media data annotation and recognition devices are mostly fixed to the inner wall surface of the control cabinet by bolts. When it is necessary to debug and repair the circuit boards, due to the large number of electrical components inside the control cabinet and the limited available space, it is inconvenient to use tools to disassemble and repair the circuit boards, which is not conducive to use.

[0004] To address this issue, a media data labeling and identification device that is easy to disassemble is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a media data labeling and identification device that is easy to disassemble, comprising: a base plate and a circuit board body, wherein two mounting plates are symmetrically fixedly installed on the upper and lower surfaces of the base plate, and mounting holes are opened on one side surface of the mounting plates; two support columns are symmetrically fixedly installed on one side surface of the base plate, and insert rods are fixedly installed on one side surface of the two support columns; through holes are symmetrically opened on one side surface of the circuit board body, and the two insert rods are correspondingly inserted into the two through holes; an electrical component group is installed on one side surface of the circuit board body; a fixing assembly is provided on one side surface of the base plate, the fixing assembly including a cross-shaped through groove, the cross-shaped through groove being opened on one side surface of the base plate; and two convex through grooves are symmetrically opened at both the upper and lower ends of one side surface of the circuit board body.

[0007] Furthermore, the two sides of the cross-shaped through groove are connected to a bidirectional threaded rod via bearings. One end of the bidirectional threaded rod movably penetrates one side of the inner wall surface of the cross-shaped through groove. A first knob is fixedly installed on one end of the bidirectional threaded rod, and the first knob is located on the outside of the base plate.

[0008] Furthermore, crossbars are fixedly installed between the multiple inner walls of the cross groove, and movable plates are movably fitted onto the surfaces of the multiple crossbars in pairs, with the two movable plates threaded onto the surfaces of the bidirectional threaded rods.

[0009] Furthermore, two hollow blocks are symmetrically fixedly installed on one side surface of each of the two movable plates, and a first disc is fixedly fitted on the outer wall surface of each of the hollow blocks, and a soft pad is fixedly installed on one side surface of each of the first discs.

[0010] Furthermore, each of the hollow blocks has a threaded rod threaded through its top surface, and a limiting plate is mounted on one end of each of the threaded rods via a bearing. The limiting plates are located inside the hollow blocks, and the four sides of the limiting plates are movably fitted to the inner wall surfaces of the hollow blocks.

[0011] Furthermore, a second disc is fixedly mounted on the other end surface of each of the multiple threaded rods, and a soft pad is fixedly mounted on one side surface of each of the multiple second discs. The circuit board body is located between the multiple second discs and the multiple first discs.

[0012] Furthermore, a second knob is fixedly installed on the other side surface of each of the second discs.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, multiple second knobs are first turned in sequence. The rotation of the second knobs drives multiple threaded rods to rotate, which in turn moves multiple second discs and multiple limiting plates. The movement of the second discs causes the circuit board body to lose its limiting position. At this time, the first knob is turned, which drives the bidirectional threaded rods to rotate. The bidirectional threaded rods drive two movable plates to move on the surface of multiple crossbars. The movement of the movable plates drives multiple hollow columns to move. When the multiple hollow columns move into the larger rectangular through slot among the multiple convex through slots, the multiple second discs no longer obstruct the circuit board body. The circuit board body can then be disassembled for inspection and repair.

[0015] When the circuit board body needs to be installed, first align the two through holes on the surface of the circuit board body with the surfaces of the two insert rods, so that multiple second discs are inserted and pass through the interior of multiple convex through slots. At this time, the hollow block part located inside the limiting plate and the first disc is located inside the convex through slot. Then, rotate the first knob in the opposite direction to drive the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives the two movable plates to move. The movement of the two movable plates drives the multiple hollow blocks to move, so that the multiple hollow blocks are located inside the smaller rectangular through slots in the multiple convex through slots. At the same time, multiple first discs are located on one side of the circuit board body. Then, rotate multiple second knobs. The rotation of multiple second knobs drives multiple threaded rods to rotate. The rotation of multiple threaded rods drives multiple second discs to rotate. The multiple second discs, together with the multiple first discs, firmly clamp and fix the circuit board body.

[0016] With the cooperation of the above structure, multiple second discs restrict the lateral movement of the circuit board body, while multiple first discs cooperate with multiple second discs to firmly clamp and fix the circuit board body to the surface of the base plate. There is no need to repeatedly remove the bolts to disassemble the circuit board body, saving the time required for maintenance personnel during installation and disassembly, and improving the convenience of installation and disassembly of the media data labeling and identification device.

[0029] Please see Figure 1-9 This utility model provides a technical solution: a media data labeling and identification device that is easy to disassemble, comprising: a base plate 1 and a circuit board body 2. Two mounting plates 3 are symmetrically fixedly installed on the upper and lower surfaces of the base plate 1. Mounting holes are opened on one side surface of the mounting plates 3.

The fixing component 7 includes a cross through groove 701, which is opened on one side surface of the base plate 1.

[0030] Specifically: The device can be installed on the inner wall surface of the control cabinet through the mounting holes on the surface of multiple mounting plates 3. The two plug rods 5 and the two through holes 6 serve to determine the installation position of the circuit board body 2. The electrical component group consists of various electrical components required to form the media data labeling and identification device. They are installed together on the surface of the circuit board body 2 to form the media data labeling and identification device. This is existing technology, and the specific structure will not be described in detail here.

[0031] In one embodiment, the two sides of the cross groove 701 are connected to a bidirectional threaded rod 702 by bearings. One end of the bidirectional threaded rod 702 movably penetrates the inner wall surface of one side of the cross groove 701. A first knob 703 is fixedly installed on one end of the bidirectional threaded rod 702. The first knob 703 is located on the outside of the base plate 1.

[0032] Specifically, such as Figure 2 As shown: the first knob 703 drives the bidirectional threaded rod 702 to rotate, and multiple first knobs 703 have a certain self-locking function.

[0033] In one embodiment, crossbars 704 are fixedly installed between multiple inner walls of the cross groove 701, and movable plates 705 are movably fitted onto the surfaces of each pair of crossbars 704. Both movable plates 705 are threaded onto the surface of the bidirectional threaded rod 702.

[0034] Specifically, such as Figure 2 As shown: the bidirectional threaded rod 702 serves to drive the two movable plates 705 to move in opposite directions on the surfaces of the multiple crossbars 704.

[0035] In one embodiment, two hollow blocks 707 are symmetrically fixedly installed on one side surface of each of the two movable plates 705, and a first disc 708 is fixedly sleeved on the outer wall surface of each of the multiple hollow blocks 707, and a soft pad is fixedly installed on one side surface of each of the multiple first discs 708.

[0036] Specifically, such as Figure 2 , 4 As shown in Figure 5: one side surface of the plurality of first disks 708 is on the same horizontal line as one side surface of the two support columns 4, and the diameter of the plurality of first disks 708 is greater than the width of the plurality of convex through slots 706.

[0037] In one embodiment, threaded rods 709 are threaded through the top surfaces of multiple hollow blocks 707, and limiting plates 710 are mounted on one end surface of each threaded rod 709 via bearings. The limiting plates 710 are located inside the multiple hollow blocks 707, and the four side surfaces of the limiting plates 710 are movably attached to the multiple inner wall surfaces of the multiple hollow blocks 707.

[0038] Specifically, such as Figure 5-7 As shown: The limiting plate 710 serves to prevent the threaded rod 709 from dislodging from the hollow block 707.

[0039] In one embodiment, a second disk 711 is fixedly mounted on the other end surface of a plurality of threaded rods 709, and a soft pad is fixedly mounted on one side surface of a plurality of second disks 711. The circuit board body 2 is located between a plurality of second disks 711 and a plurality of first disks 708.

[0040] Specifically, such as Figure 7-9 As shown: multiple first discs 708 and multiple second discs 711 serve to clamp and fix the circuit board body 2. The diameter of the multiple second discs is greater than the width of the smaller rectangular through slot among the multiple convex through slots 706, and less than the width of the larger rectangular through slot among the multiple convex through slots 706. A soft pad is provided on one side surface of the multiple first discs 708 and multiple second discs 711, which plays a protective role when clamping the circuit board body 2.

[0041] In one embodiment, a second knob 712 is fixedly mounted on the other side surface of each of the plurality of second discs 711.

[0042] Specifically, such as Figure 5 As shown: multiple second knobs 712 serve to drive multiple threaded rods 709 to rotate, and multiple second knobs 712 all have a certain self-locking function.

[0043] Working principle:

[0044] The media data labeling and identification device can be installed on the inner wall of the control cabinet through the mounting holes on the surface of multiple mounting plates 3. When it is necessary to disassemble the circuit board body 2 used for the media data labeling and identification device, firstly, turn multiple second knobs 712 in sequence. The rotation of multiple second knobs 712 drives multiple threaded rods 709 to rotate. The rotation of multiple threaded rods 709 drives multiple second discs 711 and multiple limit plates 710 to move. The movement of multiple second discs 711 causes the circuit board body 2 to lose its limit. At this time, turn the first knob 703. The rotation of the first knob 703 drives the bidirectional threaded rod 702 to rotate. The rotation of the bidirectional threaded rod 702 drives two movable plates 705 to move on the surface of multiple crossbars 704. The movement of multiple movable plates 705 drives multiple hollow columns to move. When the multiple hollow columns move into the larger rectangular through slot in multiple convex through slots 706, the multiple second discs 711 no longer block the circuit board body 2. Then the circuit board body 2 can be disassembled for inspection and maintenance.

[0045] When the circuit board body 2 needs to be installed, first align the two through holes 6 on the surface of the circuit board body 2 with the two insert rods 5, so that multiple second discs 711 are inserted and pass through the interior of multiple convex through slots 706. At this time, the hollow block 707 located inside the limiting plate 711 and the first disc 708 is located inside the convex through slot 706. Then, rotate the first knob 703 in the opposite direction to drive the bidirectional threaded rod 702 to rotate. The rotation of the bidirectional threaded rod 702 drives the two movable plates 705 to move. The movement of plate 705 causes multiple hollow blocks 707 to move, so that the multiple hollow blocks 707 are located inside the smaller rectangular through slots in multiple convex through slots 706. At the same time, multiple first discs 708 are located on one side of the circuit board body 2. Then, multiple second knobs 712 can be rotated. The rotation of multiple second knobs 712 causes multiple threaded rods 709 to rotate. The rotation of multiple threaded rods 709 causes multiple second discs 711 to rotate. The multiple second discs 711, together with the multiple first discs 708, firmly clamp and fix the circuit board body 2.

[0046] With the cooperation of the above structure, multiple second discs 711 restrict the lateral movement of the circuit board body 2, while multiple first discs 708 cooperate with multiple second discs 711 to firmly clamp and fix the circuit board body 2 to the surface of the base plate 1. There is no need to repeatedly remove the bolts to disassemble the circuit board body 2, saving the time required for maintenance personnel during installation and disassembly, and improving the convenience of installation and disassembly of the media data labeling and identification device.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
