DETAILED DESCRIPTION

[0013] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0014] Reference Figure 1-7 A DLP optical machine driving device based on FPGA includes a driving device body 1, a dustproof structure 2 is embedded and installed on one side surface of the driving device body 1, and a limiting structure 3 is fixedly installed on one side surface of the dustproof structure 2; Specifically, the dustproof structure 2 is used to perform dustproof processing on the driving device body 1 , and the limiting structure 3 is used to limit and fix the data line plugged into the driving device body 1 .

[0015] In a preferred embodiment, the driving device body 1 includes a first slide groove 101, a wiring port 102, a housing 103, a first slider 104, a limiting rod 105, and a second slide groove 106. The wiring port 102 is opened on one side surface of the housing 103. The wiring port 102 is divided into multiple groups. The first slide groove 101 is opened on one side surface of the housing 103 in front and rear of the wiring port 102. There are two groups of first slide grooves 101. The second slide groove 106 is opened on one side surface of the housing 103 in the front. The first slider 104 is embedded in the interior of the second slide groove 106. The limiting rod 105 is fixedly installed on one side surface of the first slider 104. Specifically, the optical module, hardware drive circuit module, network port to serial port module, etc. are loaded and fixed through the shell 103, and the wiring port 102 is connected to the outside world through a data cable. The second slide groove 106 is used to limit the first slider 104, and the first slider 104 can slide inside the second slide groove 106 and will not be separated from the second slide groove 106, thereby driving the limit rod 105 to move. The first slide groove 101 is located in front and behind the wiring port 102, and the second slide groove 106 is located on one side of the shell 103 in the front position and in front of the first slide groove 101, so that the first slide groove 101, the wiring port 102, and the second slide groove 106 do not interfere with each other. The installation position of the second slide groove 106 can be set as needed.

[0016] In a preferred embodiment, the dustproof structure 2 includes a dustproof plate 201, a limiting groove 202, and a second slider 203. The front surface of the dustproof plate 201 is provided with limiting grooves 202 at the top and bottom, and the limiting grooves 202 are multiple groups. The second sliders 203 are fixedly installed on the front and rear of one side surface of the dustproof plate 201, and the second sliders 203 are two groups. Specifically, the dustproof plate 201 is driven to slide by the second slider 203. The dustproof plate 201 is made of plastic and can block dust in the air. The limiting groove 202 is provided in front of the dustproof plate 201 at the upper and lower positions, so that the dustproof plate 201 can be limited to keep the dustproof plate 201 stable.

[0017] In a preferred embodiment, the second slider 203 is respectively embedded in the interior of the first slide groove 101, and the limiting rod 105 is embedded in the interior of the limiting groove 202; Specifically, the position of the dustproof plate 201 is adjusted by embedding the second slider 203 into the interior of the first slide groove 101 and sliding the second slider 203 inside the first slide groove 101. The first slider 104 is made to slide inside the second slide groove 106, so that the limit rod 105 is embedded into the interior of the limit groove 202, thereby limiting the position of the dustproof plate 201. The first slider 104 and the second slide groove 106 are fixed by friction. When there is no external force, the first slider 104 will not move inside the second slide groove 106.

[0018] In a preferred embodiment, the limiting structure 3 includes a limiting plate 301, a through groove 302, a sleeve 303, a nut 304, a threaded rod 305, an adjustment groove 306, and an inner tube 307. The inner tube 307 is embedded in the sleeve 303, and the surface of the inner tube 307 is provided with an adjustment groove 306. The threaded rod 305 is embedded in the interior of the adjustment groove 306 and the surface of the sleeve 303. The nut 304 is sleeved on the surface of the threaded rod 305. The limiting plate 301 is fixedly installed on one side surface of the inner tube 307. The lower surface of the limiting plate 301 is provided with a through groove 302, and the through grooves 302 are multiple groups. Specifically, the position of the inner tube 307 inside the sleeve 303 is adjusted, thereby adjusting the position of the limit plate 301. When in use, the data cable needs to be embedded in the through groove 302. Since the diameters of the data cables are different at the connection points, the limit plate 301 can be used to limit the data cables to prevent them from falling off. The threaded rod 305 is embedded in the sleeve 303 and extends to the surface of the sleeve 303. The surface of the sleeve 303 is provided with a movable hole, and the threaded rod 305 is located inside the movable hole. When the position needs to be adjusted, the position of the inner tube 307 inside the sleeve 303 can be adjusted. After the adjustment is appropriate, the nut 304 is put on the threaded rod 305 and tightened to fix it, so that the sleeve 303 and the inner tube 307 are fixed by extrusion, and the adjustment groove 306 is long and strip-shaped.

[0019] In a preferred embodiment, the sleeve 303 is fixedly mounted on one side surface of the dustproof plate 201 and is located at a lower position; Specifically, by fixing the sleeve 303 on one side surface of the dustproof plate 201 at a lower position, the limiting plate 301 is connected to the dustproof plate 201, and when the dustproof plate 201 moves up and down, it can drive the limiting plate 301 to move up and down.

[0020] It should be noted that when in use, the data cable is inserted into the interior of the wiring port 102 to connect the device to the drive device body 1. After the connection is completed, the inner tube 307 is moved inside the sleeve 303. After the position is adjusted appropriately, the nut 304 is put on the surface of the threaded rod 305 and tightened to fix it. The dustproof plate 201 is moved downward, so that the second slider 203 slides inside the first slide groove 101, so that the data cable is embedded in the through groove 302, and the limiting rod 105 is pushed backward so that the first slider 104 is embedded in the interior of the second slide groove 106, so that the limiting rod 105 is embedded in the interior of the limiting groove 202 to limit the dustproof plate 201. When not in use, the dustproof plate 201 can be moved down to block the wiring port 102.
