Description

Technical Field

[0001] This utility model relates to the field of industrial control chassis technology, specifically to an industrial control chassis with a flexible expandable internal space structure. Background Technology

[0002] The industrial control chassis with flexible internal space structure can easily adjust the internal space layout according to specific application needs to accommodate different types and numbers of equipment, ensuring that each piece of equipment can be installed reasonably and without interference, thereby improving the operating efficiency and reliability of the entire industrial system.

[0003] The existing technology has the following problems:

[0004] Existing devices cannot lock the position of the expansion frame during use. Industrial sites are often accompanied by mechanical vibration or accidental collisions. If the expansion frame is not locked, it may loosen, shift, or even fall off due to vibration or external force. In addition, existing devices cannot dissipate heat inside the chassis. Industrial control scenarios have extremely high requirements for computing performance. If the heat dissipation is insufficient, the core components will trigger the protection mechanism due to high temperature, forcibly reduce the frequency or even crash, resulting in system response delay or complete paralysis.

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1 As shown, this utility model provides an industrial control chassis with a flexible expandable internal space structure, including a main body 1. A motor 2 is fixedly connected to the upper side of the main body 1, and a gear 3 is fixedly connected to the output shaft of the motor 2. An expansion frame 4 is slidably connected to the rear side of the main body 1. An L-shaped support plate 7 is fixedly connected to the upper side of the expansion frame 4. A fixed frame 5 is fixedly connected to the upper side of the main body 1. Multiple insertion holes 6 are provided on both the left and right sides of the fixed frame 5. The outer wall of the L-shaped support plate 7 is slidably connected to the fixed frame 5. An air inlet pipe 17 is provided on the front side of the main body 1, and several air outlet holes 8 are provided through the rear side of the expansion frame 4. A fixing block 9 is fixedly connected to the end of plate 7 away from the expansion frame 4. The industrial control chassis of this utility model is based on the main body 1. The motor 2 outputs power to drive the gear 3 to rotate. The expansion frame 4 can slide on the rear side of the main body 1 to expand the internal space. The L-shaped support plate 7 cooperates with the fixing frame 5 to restrict the sliding direction of the expansion frame 4. Multiple holes 6 provide a position basis for subsequent locking. The air inlet pipe 17 is set on the front side of the main body 1. The air outlet 8 on the rear side of the expansion frame 4 and the air inlet pipe 17 form an air circulation channel to create conditions for heat dissipation inside the chassis. The fixing block 9 plays a key role in the subsequent locking of the expansion frame 4.

[0025] like Figure 2-3As shown, this utility model provides a technical solution: Preferably, a knob 10 is rotatably connected to the upper side of the fixing block 9, a worm gear 11 is fixedly connected to the lower side of the knob 10, a worm wheel 12 is meshed with the outer wall of the worm gear 11, a threaded rod 13 is fixedly connected through the left side of the worm wheel 12, two connecting plates 15 are threadedly connected to the outer wall of the threaded rod 13, a pin 16 is fixedly connected to the outer wall of the connecting plate 15, the outer wall of the pin 16 is movably connected to the insertion hole 6, a limiting plate 14 is fixedly connected to the right side of the inner wall of the fixing block 9, the outer wall of the limiting plate 14 is slidably connected to the connecting plate 15, both ends of the threaded rod 13 are rotatably connected to the fixing block 9, the outer wall of the worm gear 11 is rotatably connected to the fixing block 9, and the left and right ends of the outer wall of the threaded rod 13 are threaded... With the threads in opposite directions, when it is necessary to adjust and lock the position of the expansion frame 4, turn the knob 10. The knob 10 drives the worm gear 11 to rotate. Since the worm gear 11 meshes with the worm wheel 12, the worm wheel 12 rotates. When the worm wheel 12 rotates, it drives the threaded rod 13 to rotate. The threads on the left and right ends of the outer wall of the threaded rod 13 are in opposite directions. Therefore, when the threaded rod 13 rotates, the two connecting plates 15 will move towards or away from each other along the threaded rod 13 under the restriction of the limiting plate 14. When the connecting plates 15 move, they drive the insertion pin 16 to move. When the insertion pin 16 is inserted into the insertion hole 6 on the fixed frame 5, the position of the expansion frame 4 can be locked, thereby ensuring that the hardware remains in a fixed position under vibration or external force, and avoiding loosening, falling off or poor interface contact.

[0026] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a fixed plate 18 is fixedly connected to the inner wall of the air intake pipe 17, a fan 19 is fixedly connected through the front side of the fixed plate 18, a dustproof plate 23 is fixedly connected to the inner surface of the air intake pipe 17, a limiting groove 20 is opened on the front side of the air intake pipe 17, a rotating ring 21 is rotatably connected to the front side of the air intake pipe 17, a plurality of limiting posts 22 are fixedly connected to the rear side of the rotating ring 21, the outer wall of the limiting post 22 is slidably connected to the limiting groove 20, a gear ring 24 is fixedly connected to the outer wall of the rotating ring 21, the outer wall of the gear 3 is meshed with the gear ring 24, a plurality of connecting posts 25 are fixedly connected to the inner surface of the rotating ring 21, a rotating block 26 is fixedly connected to the other end of the connecting post 25, a plurality of cleaning plates 27 are fixedly connected to the rear side of the rotating block 26, and the cleaning plates 27 are cleaned. The surface is movably connected to the dustproof plate 23. The motor 2 drives the gear 3 to rotate, and the gear 3 meshes with the gear ring 24, thereby causing the rotating ring 21 to rotate. When the rotating ring 21 rotates, the limiting post 22 slides in the limiting groove 20 to ensure the stability of the rotating ring 21. The rotating ring 21 drives the rotating block 26 and the cleaning plate 27 to rotate through the connecting post 25. The cleaning plate 27 cleans the surface of the dustproof plate 23 to prevent dust accumulation from affecting heat dissipation. At the same time, the fan 19 on the fixed plate 18 works to draw external air into the chassis through the air intake pipe 17. After the air flows through the core components inside the chassis and carries away the heat, it is discharged from the air outlet 8 on the rear side of the expansion frame 4. Effective heat dissipation can ensure that the core components operate stably at the nominal frequency and avoid triggering the protection mechanism due to high temperature, thereby ensuring the system response speed and processing efficiency.

[0027] The working principle of this industrial control chassis with a flexible internal space structure will be explained in detail below.

[0028] like Figure 1-5As shown, when it is necessary to adjust and lock the position of the expansion frame 4, turn the knob 10. The knob 10 drives the worm gear 11 to rotate. Since the worm gear 11 meshes with the worm wheel 12, the worm wheel 12 rotates. When the worm wheel 12 rotates, it drives the threaded rod 13 to rotate. The threads on the left and right ends of the outer wall of the threaded rod 13 are opposite in direction. Therefore, when the threaded rod 13 rotates, the two connecting plates 15 will move towards or away from each other along the threaded rod 13 under the restriction of the limiting plate 14. When the connecting plates 15 move, they drive the insertion pin 16 to move. When the insertion pin 16 is inserted into the insertion hole 6 on the fixed frame 5, the position of the expansion frame 4 can be locked, thereby ensuring that the hardware remains in a fixed position under vibration or external force, avoiding loosening, falling off, or poor interface contact. The motor 2 drives... Gear 3 rotates and meshes with gear ring 24, thereby causing rotating ring 21 to rotate. When rotating ring 21 rotates, limiting post 22 slides in limiting groove 20 to ensure the stability of rotating ring 21. Rotating ring 21 drives rotating block 26 and cleaning plate 27 to rotate through connecting post 25. Cleaning plate 27 cleans the surface of dustproof plate 23 to prevent dust accumulation from affecting heat dissipation. At the same time, fan 19 on fixed plate 18 works to draw external air into the chassis through air intake pipe 17. After the air flows through the core components inside the chassis and carries away the heat, it is discharged from the air outlet 8 on the rear side of expansion frame 4. Effective heat dissipation can ensure that the core components operate stably at the nominal frequency and avoid triggering the protection mechanism due to high temperature, thereby ensuring system response speed and processing efficiency.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
