Description

Technical Field

[0001] The invention relates to the technical field of interface protection, and in particular to a data interface protection device for an industrial computer. Background Art

[0002] During the use of industrial computers, they are often exposed to open air, humidity, dust and other weather conditions, which often causes the data interface of the engineering machine to be blocked by dust and water droplets, resulting in loss of the data interface. Especially in humid and rainy environments, water entering the data interface will cause short circuit and leakage of the industrial computer. Therefore, it is necessary to take moisture-proof and dust-cleaning measures on the data interface of the industrial computer to realize the protection function of the data interface.

[0003] With respect to the protection of the data interface, the prior art often uses a closed cover to cover the data interface. This method can well protect the data interface when the data interface is not in use. However, when the data interface is in use, the closed cover needs to be pulled out and the data plug needs to be inserted into the data interface, which will cause the closed cover to lose its protective effect on the data interface. At the same time, the existing data interface protection covers are generally divided into a connected type and a single type. The connected type generally has multiple closed covers that are pulled out together, while the single type has each closed cover independently inserted into a different data interface. However, when only one data interface is in use, the other closed covers must also be opened, and the protection function for other data interfaces cannot be achieved. The single type is cumbersome to operate. After opening a closed cover alone, if it is not properly kept, the closed cover will be lost. Therefore, there is a need for an industrial computer data interface protection device that can protect the interface when the data interface is in use or not in use, and can also independently protect each data interface while being convenient to open, so as to solve the shortcomings of the existing data interface protection devices.

[0004] For example, the patent with announcement number CN112506293B provides a data interface protection device for an intelligent industrial computer, which includes a No. 1 box body, a wire slot, and a limit hole, and the wire slot is used to protect the data line of the data plug. The application is easy to operate, can protect the wires at the plug, improve practicality, and can also be ventilated in time to avoid dust on unused interfaces; when a fault occurs, the solution cannot quickly disassemble and install the protection device, thereby reducing the flexibility of the solution; the solution cannot actively isolate dust when the data interface is in use or not in use; at the same time, the solution cannot automatically clean the isolated dust, nor can it use the wind that cleans the dust to dissipate the heat of the data interface; although the solution can protect the wires of the plug, it cannot achieve anti-bending protection for the plug body when the plug is directly hit and bent; the solution cannot synchronously control the opening and closing of multiple interfaces, which makes it inconvenient for staff to insert multiple data plugs.

[0043] Working principle of the present invention: Figure 1 and Figure 2 The usage and corresponding scenarios of the present invention are given. The posture control of the data interface protection process is determined by the splicing device 1, the shielding device 2 and the dust collection device 5. The posture of the splicing device 1 is determined by the shielding device 2, and the posture of the dust collection device 5 is determined by the shielding device 2. Therefore, the shielding device 2 is the core of the data interface protection process.

[0044] Taking the first embodiment as an example, the splicing device 1 drives the splicing slide bar 201 of the shielding device 2 to move forward and backward by engaging the splicing teeth 103 with the splicing groove 202 and then rotating the splicing wheel 102, thereby realizing the sliding of the shielding device 2 on the splicing device 1, and also inserting the crescent plug block 105 into the crescent slot 107, so that the splicing wheel 102 cannot continue to rotate, thereby realizing the quick disassembly and assembly function of the shielding device 2 and the splicing device 1. The shielding slide plate 203 on the manually sliding shielding device 2, during the sliding process of the shielding slide plate 203, the shielding protrusion 217 on the slide plate body 214 will prevent the shielding baffle 204 from opening, at this time, the shielding slide plate 203 drives the differential wheel 218 on the differential assembly 207 to rotate on the third shaft 224, when the shielding protrusion 217 is removed from above the shielding baffle 204, the differential wheel 218 will drive the third shaft 224 to rotate, the third shaft 224 drives the first shaft 209 and the second gear 211 to rotate through the first gear 208, the second gear 211 drives the shielding baffle 204 to open through the second shaft 210, so as to realize the quick conversion between the sealing mode and the working mode. When the data plug is inserted, the data plug will squeeze the inclined surface of the inclined slider 506 to drive the dust collecting device 5 to open outward. When the data plug is fully inserted, the inclined slider 506 will clamp the data plug, and the wrapping frame 403 of the protection component 4 will wrap the data plug, thereby realizing the anti-compression bending protection function after the data plug is inserted. After the heat dissipation fan 604 on the heat dissipation component 6 is turned on, the outside air will be sucked into the air storage groove 504 of the dust collecting device 5 through the first air inlet 501 and the second air inlet 502, and the dust filtered on the inclined slider 506 will also be sucked into the air storage groove 504 to realize the self-cleaning function. Then the dust and wind enter the air storage chamber 601 through the air inlet pipe 603, and then the dust is filtered by the dust plate 602, so that the clean wind is blown out from the heat dissipation fan 604 to realize the heat dissipation and dust collection functions; the dust shielding component 3 is used to prevent large debris from entering between the first gear 208 and the second gear 211.

[0045] Specifically, Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the splicing teeth 103 on the splicing wheel 102 are meshed with the splicing grooves 202 on the splicing slide bar 201, and then the crescent plug block 105 and the locking slide column 106 are manually rotated, and the locking slide column 106 drives the splicing wheel 102 to rotate, and the splicing wheel 102 drives the splicing slide bar 201 to move back and forth, so that the shielding device 2 slides on the splicing base 101, and the crescent plug block 105 is pressed down so that the crescent plug block 105 is inserted into the crescent slot 107, so that the splicing wheel 102 cannot continue to rotate. Then, the semicircular locking plate 104 is rotated so that the semicircular locking plate 104 rotates to the top of the crescent plug 105 to prevent the crescent plug 105 from popping out, thereby realizing the quick disassembly and assembly function of the shielding bottom plate 205 and the splicing device 1; the slide body 214 on the shielding slide plate 203 is manually driven to slide on the shielding slide groove 206. During the sliding process of the shielding slide plate 203, the shielding protrusion 217 on the slide body 214 will prevent the shielding baffle 204 from opening. At this time, the push-pull slide bar 215 passes through the push-pull teeth 216 and the differential groove 219 is engaged to drive the differential rotating wheel 218 on the differential assembly 207 to rotate. At this time, the third rotating shaft 224 cannot rotate because the shielding baffle 204 cannot be opened, so that the differential rotating wheel 218 can rotate freely on the third rotating shaft 224. At this time, the extrusion force will squeeze the differential round head pin 221 from the second locking groove 223 back into the differential rotating wheel 218. When the shielding protrusion 217 is removed from the top of the shielding baffle 204, the differential rotating wheel 218 will drive the differential round head pin 221 to reach the first locking groove 222 At this time, the differential spring 220 drives the differential round head pin 221 to pop out into the first locking groove 222, so that the differential wheel 218 rotates together with the third shaft 224, and the third shaft 224 drives the first shaft 209 and the second gear 211 to rotate through the first gear 208, and the second gear 211 drives the shielding baffle 204 to open through the second shaft 210, so that the protection interface 212 is opened, so as to realize the quick conversion between the sealing mode and the working mode; the horizontal slide groove 213 is used for sliding installation of the dust collection device 5.

[0046] like Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, when the data plug is inserted, the data plug will squeeze the inclined surface of the inclined slider 506 to drive the inclined slider 506 to slide in the horizontal slide groove 213, so that the protection interface 212 and the data interface are opened. When the data plug is fully inserted, the pressure spring 505 drives the inclined slider 506 to rebound, thereby clamping the data plug; after the shielding baffle 204 is opened, the protection spring 402 on the protection bracket 401 drives the parcel rack 403 to clamp inward, so that the parcel rack 403 can completely wrap the data plug, thereby realizing the anti-compression bending protection function after the data plug is inserted; after the cooling fan 604 is turned on, the cooling fan 604 will suck the outside air into the air storage groove 504 through the first air inlet 501 and the second air inlet 502, and at the same time, the inclined slider 506 The filtered dust is also sucked into the air storage groove 504 to achieve the self-cleaning function; then the dust and wind enter the air storage chamber 601 through the air inlet pipe 603, and then the dust is filtered by the dust filter plate 602, so that the clean wind is blown out from the cooling fan 604 to achieve the heat dissipation and dust collection functions; in the process of opening the shielding baffle 204, the shielding baffle 204 will drive the flexible baffle 302 on the fixed support plate 301 to flexibly deform, so as to adapt to the opening of the shielding baffle 204; the fixed support plate 301 and the flexible baffle 302 are also used to prevent large debris from entering between the first gear 208 and the second gear 211; the heat dissipation hole 503 is used to dissipate heat in the data interface; when the dust in the air storage chamber 601 is full, the cleaning slide 605 is manually opened to clean the dust.

[0047] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
