Description
Technical Field
[0001] This invention relates to an industrial control computer, and more particularly to a simplified embedded industrial control computer. Background Technology
[0002] An industrial control computer, also known as an industrial control computer, is used in the industrial field to connect with common industrial control devices such as industrial cameras, light source controllers, displays, and various sensors, thereby assisting industrial production and work. Depending on the needs, industrial PCs vary in type and function. One type, the simplified embedded industrial PC, uses air cooling and is installed in an embedded manner. Its internal components are compact, resulting in a small overall size, hence the name "simplified embedded industrial PC" or "compact embedded industrial PC." Traditional simplified embedded industrial PCs, while possessing strong data transmission capabilities, typically include multiple interfaces such as USB, COM, DVI, and VGA. This increased number of interfaces, while maintaining a compact structure, reduces the space between them, leading to a more compact arrangement. This compact arrangement can cause difficulties in plugging and unplugging data connectors, as the small gaps between interfaces make it difficult to hold the plugs, especially when multiple rows of interfaces are connected to data connectors. The data cables and connectors further occupy space, making plugging and unplugging inconvenient. Furthermore, traditional industrial PCs are limited by the industrial environment. Due to factors such as vibration and shaking, data connectors often experience loose connections, necessitating frequent plugging and unplugging. This not only causes inconvenience but also impacts connected equipment and industrial production. Furthermore, the compact interface arrangement, after insertion, becomes cluttered due to the resilience of the data cable. To organize the cables, cable ties are often used for bundling, achieving a tidy environment. However, bundling restricts the insertion and unplugging of certain connectors. The support provided by the data cable to the connector is limited, especially for stiffer data cables, making it difficult to significantly change the plug's position. Even if there is contact, the connection may still be loose. In this case, unplugging and replugging the connector is not only hindered by the resistance of the data cable but also by the force exerted on other connectors due to the bundling effect, affecting their stability and causing loose connections. This highlights the shortcomings of the cable ties. Summary of the Invention
[0003] The purpose of this invention is to provide a simplified embedded industrial control computer to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A simplified embedded industrial control computer includes a main body, a filter screen, support shafts, limit bolts, a mounting base, through holes, an upper data interface, a middle data interface, a lower data interface, a support base, limit holes, and an adjustment section. Vertical filters are fixed to the front and rear of the main body, and horizontal support shafts are fixed to the middle of the left and right ends of the main body. Limit bolts are threadedly connected to the front and rear of each of the left and right ends. The two support shafts are rotatably connected to horizontal, L-shaped mounting bases. Each mounting base has through holes for inserting bolts, and each limit bolt passes through the mounting base and is connected to the mounting plate. The mounting base is interlocked with the main body, which houses the motherboard and cooling fan. Multiple horizontal upper, middle, and lower data interfaces are fixed to the front and rear of the motherboard from top to bottom. These interfaces are interlocked with the main body and exposed to the outside. Multiple horizontal support bases are fixed to both the front and rear ends of the main body. Each support base is interlocked with each upper and lower data interface. The support bases are cylindrical in shape and have vertical limiting holes penetrating their upper and lower parts. All support bases share an adjustment mechanism.
[0006] Based on the above technical solution, the adjustment part includes a support socket, a partition groove, an elastic plate, a limiting protrusion, a silicone strip, an upper ratchet, a lower ratchet, a limiting plate, a limiting groove, a support frame, a limiting shaft, an incomplete ratchet gear, a blank area, and a traction part. Each support base has a horizontal support socket inserted into its inner wall, and vertical partition grooves penetrate both its upper and lower parts. The top view of the partition grooves is U-shaped. The upper and lower parts of the support sockets are separated by the partition grooves to form two horizontal elastic plates. Limiting protrusions are fixed to the root of each elastic plate connected to the support socket, and horizontal silicone strips are fixed to the adjacent ends away from the root in the left-right direction. The silicone strips are ratchet-shaped and point towards the support base. The upper end of the inner wall of the support socket... Multiple upper ratchet teeth in the same direction are fixed on both the left and right sides along the front-back direction, and multiple lower ratchet teeth in the same direction are fixed on both the left and right sides at the bottom of the inner wall along the front-back direction. The direction of the upper ratchet teeth is opposite to that of the lower ratchet teeth. A horizontal limiting plate is fixed on each of the left and right sides of the support socket in the front-back direction. A horizontal limiting groove runs through the front part of the limiting plate in the left-back direction. A support frame is installed on the part of each support socket away from the support base. A horizontal limiting shaft is fixed on each of the left and right sides of the support frame in the left-back direction. An incomplete ratchet gear is coaxially fixed on the part of each limiting shaft away from the support frame and is interlocked with the limiting groove. The incomplete ratchet gear has a blank area on both the upper and lower parts. A traction part is installed on each of the support frames.
[0007] Based on the above technical solution, after the limiting bolt is removed, the mounting base can still allow the limiting bolt to be inserted into the gap and threadedly connected to the main body after rotating 180 degrees around the support shaft. When the support socket is inserted into the support base, the limiting protrusion can be inserted into the limiting hole without deformation of the elastic plate. When the support socket is inserted into the support base, the two elastic plates on it can be elastically deformed and move closer to each other, allowing the limiting protrusion to disengage from the limiting hole. The limiting shaft can rotate and slide back and forth in the limiting groove. The lower ratchet corresponding to the lower data interface points to the lower data interface, and the upper ratchet corresponding to the upper data interface points to the upper data interface. The blank area will have incomplete ratchet. The ratchet of the gear is divided into front and rear parts. When the limiting shaft rotates, it enables the ratchet part of the incomplete ratchet gear to mesh with the upper and lower ratchet simultaneously. When the limiting shaft rotates, it enables the upper and lower ratchet simultaneously to engage in the blank area of the incomplete ratchet gear. When the upper and lower ratchet simultaneously engage in the blank area of the incomplete ratchet gear, the limiting shaft can slide back and forth along the limiting groove under the action of external force. When the upper and lower ratchet simultaneously engage in the blank area of the incomplete ratchet gear, the support frame corresponding to the upper data interface is in a downward tilted state. When the upper and lower ratchet simultaneously engage in the blank area of the incomplete ratchet gear, the support frame corresponding to the lower data interface is in an upward tilted state.
[0008] Based on the above technical solution, the traction part includes a left insertion hole, a right insertion hole, an elastic rope, a left plug, a right plug, elastic plates, and a limiting circular plate. Each support frame has a horizontal left insertion hole penetrating its left side in the left-right direction, and a horizontal right insertion hole penetrating its right side in the left-right direction. A horizontal left plug is fixed to the left end of the elastic rope, and a right plug is fixed to its right end. The middle of both the left and right plugs is cylindrical, and the ends away from the elastic rope are conical. Multiple elastic plates are fixed at equal angles around the circumference of the ends of the left and right plugs away from the elastic rope, and the portions near the elastic rope... Each plug is coaxially fixed with a limiting circular plate. The direction of the elastic plate is the same as the direction of the cone surface of the cone-shaped left and right plugs. Each left plug is interposed with the left socket, and each right plug is interposed with the right socket. The elastic plate of each left plug is located to the left of the left socket, and the limiting circular plate of each left plug is located to the right of the left socket. When the left plug is inserted into the left socket, it is prevented from falling out of the left socket by the elastic plate and the limiting circular plate. When the right plug is inserted into the right socket, it is prevented from falling out of the right socket by the elastic plate and the limiting circular plate.
[0009] Compared with the prior art, the present invention has the following advantages: the insertion of the limiting protrusion and the limiting hole can prevent the support socket from moving away from the support base, while the ratchet-shaped silicone strip facilitates the insertion of the data connector and prevents the data plug from moving away from the support base, thus ensuring the stability of the insertion. The limiting shaft's ability to rotate within the limiting groove and slide back and forth allows control over whether the incomplete ratchet gear meshes with the upper and lower ratchet teeth, thereby adjusting the vertical angle and front-back position of the support frame relative to the support base. Simultaneously, under the tension of the elastic rope, it can not only monitor external data... The connector is pulled towards the support base, thereby further improving the stability of the external data plug connection. It can also select an appropriate bending radius to bend the external data cable according to its different softness, hardness and thickness. This avoids damage to the data cable due to an excessively small bending radius, while increasing the vertical gap between the data cables to achieve the purpose of clearing the circuit. The mutual squeezing of the elastic plate can release the connection between the limiting protrusion and the limiting hole. At the same time, the silicone strip can tightly squeeze the external data connector, making it easy to pull out the external data plug and the support socket together. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figures 1-5 As shown, a simplified embedded industrial control computer includes a main body 1, a filter screen 2, a support shaft 3, a limiting bolt 4, a mounting base 5, a through hole 6, an upper data interface 7, a middle data interface 8, a lower data interface 9, a support base 10, a limiting hole 11, and an adjustment part 12. Vertical filters 2 are fixed to the front and rear of the main body 1, facilitating air cooling by the internal cooling fan. Horizontal support shafts 3 are fixed to the middle of the left and right ends of the main body 1, and limiting bolts 4 are threaded to the front and rear of both ends. The limiting bolts 4 restrict the relative position of the mounting base 5 and the main body 1. The two support shafts 3 are rotatably connected to horizontal, "L"-shaped mounting bases 5. The mounting base 5 has through holes 6 for inserting bolts, facilitating fixing of the mounting base 5. Each limiting bolt 4 passes through the mounting base. 5. It is interlocked with the mounting base 5. The main body 1 is equipped with a motherboard and a heat sink. The motherboard has multiple horizontal upper data interfaces 7, middle data interfaces 8 and lower data interfaces 9 fixed from top to bottom on both the front and rear sides. The upper data interfaces 7, middle data interfaces 8 and lower data interfaces 9 are known interfaces in the prior art, such as USB interfaces, COM interfaces, DVI interfaces and VGA interfaces. The upper data interfaces 7, middle data interfaces 8 and lower data interfaces 9 are respectively interlocked with the main body 1 and exposed to the outside. Multiple horizontal support bases 10 are fixed at both the front and rear ends of the main body 1. Each support base 10 is interlocked with each upper data interface 7 and lower data interface 9. The support base 10 has a square cylindrical structure and vertical limiting holes 11 pass through the upper and lower parts. Each support base 10 is equipped with an adjustment part 12.
[0018] The adjusting part 12 includes a support socket 13, a partition groove 14, an elastic plate 15, a limiting protrusion 16, a silicone strip 17, an upper ratchet 18, a lower ratchet 19, a limiting plate 20, a limiting groove 21, a support frame 22, a limiting shaft 23, an incomplete ratchet gear 24, a blank area 25, and a traction part 26. Each of the support seats 10 has a horizontal support socket 13 inserted into its inner wall, and vertical partition grooves 14 penetrate both the upper and lower parts. The top view projection of the partition groove 14 is U-shaped. The upper and lower parts of the support socket 13 are separated by a partition groove 14 to form two horizontal elastic plates 15. Limiting protrusions 16 are fixed to the root of each elastic plate 15 where it connects to the support socket 13. Horizontal silicone strips 17 are fixed to adjacent ends away from the root in the left-right direction. These silicone strips 17 are ratcheted and point towards the support base 10, thereby facilitating insertion of the support socket 13 while increasing the resistance to removal, thus ensuring the stability of the external data connector connection. The inner wall of the support socket 13... Multiple upper ratchet teeth 18 are fixed in the same direction on the left and right sides of the upper end along the front and back direction, and multiple lower ratchet teeth 19 are fixed in the same direction on the left and right sides of the bottom of the inner wall along the front and back direction. The direction of the upper ratchet teeth 18 is opposite to that of the lower ratchet teeth 19. Horizontal limiting plates 20 are fixed on the left and right sides of the support socket 13 in the front and back directions. Horizontal limiting grooves 21 penetrate the front part of the limiting plate 20 in the left and right directions. The limiting grooves 21 are used to limit the vertical and horizontal positions of the limiting shaft 23, thereby limiting the vertical and horizontal positions of the support frame 22. Support frames 22 are installed on the parts of each support socket 13 away from the support base 10. Horizontal limiting shafts 23 are fixed on the left and right sides of each support frame 22 in the left and right directions. Incomplete ratchet gears 24 are coaxially fixed on the parts of each limiting shaft 23 away from the support frame 22, and are interlocked with the limiting grooves 21. Blank areas 25 are provided on the upper and lower parts of each incomplete ratchet gear 24. Traction parts 26 are installed on each support frame 22.
[0019] After the limiting bolt 4 is removed, the mounting base 5 can still be threadedly connected to the main body 1 while the limiting bolt 4 is inserted into the gap with the support shaft 3 after rotating 180 degrees around the support shaft 3. When the support socket 13 is inserted into the support base 10, the limiting protrusion 16 can be inserted into the limiting hole 11 without deformation of the elastic plate 15. When the support socket 13 is inserted into the support base 10, the two elastic plates 15 on it can be elastically deformed and move closer to each other, so that the limiting protrusion 16 can disengage from the limiting hole 11. The limiting shaft 23 can... The gear can rotate and slide back and forth within the limiting groove 21. The lower ratchet 19 corresponding to the lower data interface 9 points to the lower data interface 9, and the upper ratchet 18 corresponding to the upper data interface 7 points to the upper data interface 7. The blank area 25 divides the ratchet of the incomplete ratchet gear 24 into two parts. When the limiting shaft 23 rotates, it allows the ratchet portion of the incomplete ratchet gear 24 to mesh with both the upper ratchet 18 and the lower ratchet 19 simultaneously. When the limiting shaft 23 rotates, it allows both the upper ratchet 18 and the lower ratchet 19 to simultaneously engage with the incomplete ratchet gear 24. When the upper ratchet 18 and lower ratchet 19 simultaneously engage with the incomplete ratchet gear 24 within the blank area 25 of the 4th ratchet, the limiting shaft 23 can slide back and forth along the limiting groove 21 under the action of external force. That is, at this time, the incomplete ratchet gear 24 does not mesh with the upper ratchet 18 and lower ratchet 19. When the upper ratchet 18 and lower ratchet 19 simultaneously engage with the incomplete ratchet gear 24 within the blank area 25 of the 4th ratchet, the support frame 22 corresponding to the upper data interface 7 is in a downward tilted state, which facilitates the insertion of external data connectors into the upper data interface 7. To ensure that the position of the support frame 22 can be restricted by the meshing of the incomplete ratchet gear 24 with the upper ratchet 18 and the lower ratchet 19 after the support frame 22 is pushed up, when the upper ratchet 18 and the lower ratchet 19 are simultaneously engaged in the blank area 25 of the incomplete ratchet gear 24, the support frame 22 corresponding to the lower data interface 9 is in an upward tilted state, which facilitates the insertion of the external data connector and the lower data interface 9. At the same time, to ensure that the position of the support frame 22 can be restricted by the meshing of the incomplete ratchet gear 24 with the upper ratchet 18 and the lower ratchet 19 after the support frame 22 is pushed down.
[0020] The traction part 26 includes a left insertion hole 27, a right insertion hole 28, an elastic rope 29, a left plug 30, a right plug 31, elastic pieces 32, and a limiting circular plate 33. Each support frame 22 has a horizontal left insertion hole 27 penetrating its left side in the left-right direction and a horizontal right insertion hole 28 penetrating its right side in the left-right direction. The elastic rope 29 has a horizontal left plug 30 fixed to its left end and a right plug 31 fixed to its right end. Both the left plug 30 and right plug 31 are cylindrical in the middle, and their ends away from the elastic rope 29 are conical. Multiple elastic pieces 32 are fixed at equal angles around the ends of the left plug 30 and right plug 31 away from the elastic rope 29, and a limiting circular plate 33 is coaxially fixed to the portions near the elastic rope 29. The direction of the elastic pieces 32 is... The cone-shaped left plug 30 and right plug 31 have the same cone surface direction, which facilitates the insertion of the left plug 30 into the left socket 27 and the right plug 31 into the right socket 28. Each of the left plugs 30 is inserted into the left socket 27 with a gap, and each of the right plugs 31 can be inserted into the right socket 28 with a gap. The elastic piece 32 of each of the left plugs 30 is located to the left of the left socket 27, and the limiting round plate 33 of each of the left plugs 30 is located to the right of the left socket 27. When the left plug 30 is inserted into the left socket 27, it can be prevented from falling out of the left socket 27 by the elastic piece 32 and the limiting round plate 33. When the right plug 31 is inserted into the right socket 28, it can be prevented from falling out of the right socket 28 by the elastic piece 32 and the limiting round plate 33.
[0021] The working principle of this invention: Initially, the upper ratchet 18 and lower ratchet 19 are integrated into the blank area 25, that is, the support frame 22 corresponding to the upper data interface 7 tilts downward, and the support frame 22 corresponding to the lower data interface 9 tilts upward. The left plug 30 is inserted into the left socket 27. The mounting base 5 is rotated accordingly as needed to adjust the installation position of the main body 1. For example, when it is necessary to make the main body 1 close to the bottom of a certain plane, the limiting bolt 4 can be removed first, and then the mounting base 5 can be rotated 180 degrees around the support shaft 3 and then the limiting bolt 4 can be reinstalled, thereby changing the position of the mounting base 5 relative to the main body 1, so that the mounting base 5 is inverted. At this time, the bottom of the mounting base 5 is close to the bottom of the plane. Therefore, at this time, the mounting base 5, through hole 6 and bolts, etc. Fasteners can be used to install the main body 1 below a certain plane. External data connectors are then plugged into the corresponding upper data interface 7, middle data interface 8, and lower data interface 9. When plugging into the upper data interface 7 and lower data interface 9, the external data connector should first be plugged into the support socket 13, and then into the corresponding upper data interface 7 and lower data interface 9. When the external data connector is plugged into the support socket 13, the upper and lower end faces of the external data connector will exert an expanding pressure on the silicone strip 17 (this can be achieved by replacing the support socket 13 with silicone strips 17 of different sizes). The ratchet-shaped silicone strip 17 pointing towards the support base 10 not only facilitates the insertion of the external data plug, but also... Furthermore, it can prevent external data plugs from detaching from the corresponding upper data interface 7 or lower data interface 9. Then, the elastic cord 29 can be wrapped around the external connector or the transition section between the external connector and the external data cable several times before the right plug 31 is inserted into the right socket 28. This ensures that the right plug 31 is confined within the right socket 28 by the elastic plate 32 and the limiting disc 33, preventing it from falling off. Next, the position of the limiting shaft 23 within the limiting groove 21 is adjusted so that the limiting shaft 23 is as close as possible to the support base 10, while simultaneously ensuring the elastic cord 29 is under significant elastic tension. Then, the support frame 22 directly in front of the upper data interface 7 is pulled up, or the support frame 22 directly in front of the lower data interface 9 is pulled down, ensuring that each support frame 22 is in a relatively stable position. In a horizontal position, during rotation, the incomplete ratchet 24 causes its ratchet teeth to expand and compress the upper and lower parts of the support socket 13. This allows the ratchet teeth of the incomplete ratchet 24 to simultaneously mesh with the upper ratchet 18 and the lower ratchet 19, preventing the ratchet from rotating in the opposite direction and thus preventing the support frame 22 from returning to its original tilted state. It also prevents the incomplete ratchet 24 from sliding back and forth relative to the upper and lower ratchet teeth 18 and 19, thus preventing the support frame 22 from moving back and forth relative to the support socket 13. At this time, the elastic rope 29 also remains elastically stretched, allowing the external data connector to be pulled towards the support base 10 using the tension of the elastic rope 29, while the support frame 22 does not move back and forth relative to the support socket 13.The support socket 13, compared to the support base 10, does not move back and forth under the action of the limiting protrusion 16 and the limiting hole 11, thus helping to improve the stability of the external data connector insertion. If the elastic cord 29 is not needed to improve the insertion stability but the cable needs to be tidied, after inserting the external data connector through the support socket 13 and plugging it into the corresponding upper data interface 7 and lower data interface 9, wrap the elastic cord 29 around the external data cable several times before inserting the right plug 31 into the right socket 28. The right plug 31 is then restricted within the right socket 28 by the elastic piece 32 and the limiting circular plate 33, thus preventing the right plug 31 from falling off. Then, pull up the support frame 22 directly in front of the upper data interface 7 and pull down the support frame 22 directly in front of the lower data interface 9, so that the support frame 22 directly in front of the upper data interface 7 is in an upward tilted state and the support frame 22 directly in front of the lower data interface 9 is in a downward tilted state, thus bending the data cable corresponding to the upper data interface 7 upward. The data cable corresponding to the lower data interface 9 is bent downwards to increase the vertical gap between the data cables, thereby clarifying the wiring. Before moving the support bracket 22, the position of the limiting shaft 23 in the limiting groove 21 can be adjusted according to the thickness and hardness of the external data cable, thereby indirectly adjusting the position of the support bracket 22 relative to the support base 10. Then, when moving the corresponding support bracket 22, the bending radius of the data cable is adjusted, ensuring that the wiring is cleared while ensuring reasonable bending of the data cable, thus avoiding damage due to an excessively small bending radius. When it is necessary to unplug the data connector, the elastic plates 15 on both the upper and lower parts of the same support socket 13 are squeezed simultaneously by the thumb and forefinger. The ratchet structure and elastic properties of the silicone strip 17 facilitate the proximity of the elastic plates 15, thereby allowing the limiting protrusion 16 to disengage from the limiting hole 11. At the same time, the silicone strip 17 can be used to tightly squeeze the external data connector, making it easy to unplug the external data plug and the support socket 13 together.
[0022] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.

When the plates (15) elastically deform and move closer to each other, the limiting protrusion (16) can disengage from the limiting hole (11). The limiting shaft (23) can rotate and slide back and forth in the limiting groove (21). The lower ratchet (19) corresponding to the lower data interface (9) points to the lower data interface (9), and the upper ratchet (18) corresponding to the upper data interface (7) points to the upper data interface (7). The blank area (25) divides the ratchet of the incomplete ratchet gear (24) into two parts. When the limiting shaft (23) rotates, it enables the ratchet portion of the incomplete ratchet gear (24) to simultaneously mesh with the upper ratchet (18) and the lower ratchet (19). When the limiting shaft (23) rotates, it enables the upper ratchet (18) and the lower ratchet (19) to simultaneously engage in the blank area (25) of the incomplete ratchet gear (24). When the upper ratchet (18) and the lower ratchet (19) simultaneously engage in the blank area (25) of the incomplete ratchet gear (24), the limiting shaft (23) is on the outside. Under the action of force, it can slide back and forth along the limiting groove (21). When the upper ratchet (18) and the lower ratchet (19) are simultaneously integrated into the blank area (25) of the incomplete ratchet gear (24), the support frame (22) corresponding to the upper data interface (7) is in a downward tilting state. When the upper ratchet (18) and the lower ratchet (19) are simultaneously integrated into the blank area (25) of the incomplete ratchet gear (24), the support frame (22) corresponding to the lower data interface (9) is in an upward tilting state.
3. A simplified embedded industrial control computer according to claim 1, characterized in that: The traction part (26) includes a left insertion hole (27), a right insertion hole (28), an elastic rope (29), a left plug (30), a right plug (31), elastic plates (32), and a limiting circular plate (33). Each of the support frames (22) has a horizontal left insertion hole (27) penetrating its left side in the left-right direction, and a horizontal right insertion hole (28) penetrating its right side in the left-right direction. The left end of the elastic rope (29) is fixed with a horizontal left plug (30), and the right end is fixed with a right plug (31). The middle of the left plug (30) and the right plug (31) are both cylindrical, and the ends away from the elastic rope (29) are both conical. The ends of the left plug (30) and the right plug (31) away from the elastic rope (29) are respectively fixed with multiple elastic plates (32) at equal angles around their circumference, and the parts close to the elastic rope (29) are respectively fixed with a limiting circular plate (33) on the same axis. The plate (33) has the same direction as the cone surface of the cone-shaped left plug (30) and right plug (31). Each left plug (30) is interleaved with the left socket (27), and each right plug (31) is interleaved with the right socket (28). The elastic piece (32) of each left plug (30) is located to the left of the left socket (27), and the limiting round plate (33) of each left plug (30) is located to the right of the left socket (27). When the left plug (30) is interleaved with the left socket (27), it is prevented from falling out of the left socket (27) by the elastic piece (32) and the limiting round plate (33). When the right plug (31) is interleaved with the right socket (28), it is prevented from falling out of the right socket (28) by the elastic piece (32) and the limiting round plate (33).
