Description

A type of main control cabinet air conditioner fan Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and more specifically, it relates to a main electrical cabinet air conditioning fan. Background Technology

[0002] In modern electrical equipment, especially inside important electrical equipment such as distribution cabinets and control cabinets, temperature control and environmental cleanliness are key factors to ensure stable operation. To this end, air conditioning fan systems are usually installed to reduce the internal temperature of the cabinet and prevent the equipment from being damaged by overheating. At the same time, since the cabinet is usually in a dusty environment, the air conditioning fan system is usually equipped with filter plates to ensure that the equipment is not affected by dust. The filter plates filter dust and impurities in the air to ensure that the air flowing into the cabinet is clean. However, over time, the filter plates will become clogged due to the accumulation of dust, resulting in a decrease in fan efficiency. Therefore, regularly replacing or cleaning the filter plates has become an important task of equipment maintenance.

[0003] However, in the existing technology, the replacement and cleaning of filter plates often require a certain amount of time and effort. Traditional filter plate designs are inconvenient to disassemble and install, and may require the use of special tools or relatively complicated disassembly and assembly procedures, which brings considerable trouble to daily maintenance. This is especially true in situations where filter plates need to be replaced frequently, where the complexity and time consumption of the operation become particularly prominent. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a main electrical cabinet air conditioning fan to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

The outer wall of the rod has multiple sets of abutment plates that rotate on the inner wall of the fixed sleeve. The connecting plate is hinged to the bottom end of the abutment plate. Multiple sets of sliding grooves are distributed on the outer wall of the fixed sleeve. The sliding sleeve slides in multiple sets of sliding grooves and is hinged to multiple sets of connecting plates. The limiting mechanism includes a limiting sleeve, a limiting groove, a rotating sleeve, a sliding rod, and a limiting block. The limiting sleeve is fixed to the outer wall of the sliding sleeve. Multiple sets of limiting grooves are distributed on the outer wall of the limiting sleeve. The rotating sleeve rotates on the outer wall of the fixed sleeve. Multiple sets of sliding rods are fixed to the bottom surface of the rotating sleeve and slide in multiple sets of limiting grooves. The limiting block is fixed to the bottom end of multiple sets of sliding rods.

[0008] The present invention is further configured such that the insertion rod is polygonal, and a positioning hole is provided inside the fixing sleeve. The positioning hole is adapted to the insertion rod, which enhances the stability of the insertion and prevents the insertion rod from rotating or loosening during use.

[0009] The present invention is further configured such that each of the multiple sets of limiting grooves has an unlocking hole at one end, which facilitates quick release of the limiting when needed and improves the disassembly efficiency of the system.

[0010] The present invention is further configured such that the diameter of each of the multiple sets of unlocking holes is larger than that of the limiting block, so as to ensure that the unlocking operation can pass smoothly through the limiting block and avoid the limiting block from jamming the unlocking hole, which would lead to unlocking failure.

[0011] The present invention is further configured such that a push spring is connected to the top surface of the limiting sleeve, and a thrust bearing is connected between the top end of the push spring and the rotating sleeve, which ensures the stable transmission of thrust and improves the cooperation effect between the limiting sleeve and the rotating sleeve.

[0012] The present invention is further configured such that a reset mechanism is provided on the top surface of the rotating sleeve. The reset mechanism includes a mounting block, an arc rod, a pressing plate, and a pressing spring. Multiple sets of mounting blocks are fixed to the top surface of the rotating sleeve. Multiple sets of arc rods are respectively fixed to the outer wall of multiple sets of mounting blocks. Multiple sets of pressing plates are fixed to the outer wall of the fixed sleeve and are slidably connected to multiple sets of arc rods. Multiple sets of pressing springs are provided, with their two ends respectively connected to the mounting block and the pressing plate, ensuring that all components can automatically reset after installation, thereby improving the stability and working efficiency of the system.

[0013] The present invention is further configured such that multiple sets of compression springs are respectively arranged on the outer side of multiple sets of arc-shaped rods, thereby optimizing the pressure distribution of the compression springs and improving the uniformity of the reset effect.

[0014] The present invention is further configured such that the mounting plate has a socket, which is adapted to the plug rod, thereby enhancing the fitting accuracy between the mounting plate and the plug rod and ensuring a firm connection during the installation process.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a main electrical cabinet air conditioning fan, which has the following beneficial effects:

[0017] 1. The snap-fit ​​mechanism achieves a secure connection between the mounting plate and the fixed plate through precise design. Furthermore, the cooperation between the insert rod and the fixing sleeve allows the mounting plate to be quickly separated from the fixed plate when disassembly is required, greatly improving the convenience of filter plate replacement. Specifically, the snap-fit ​​mechanism achieves a stable snap-fit ​​effect through the insertion structure between the insert rod and the fixing sleeve. The included slot and abutment plate secure the insert rod in the mounting plate, preventing loosening due to inaccurate positioning during installation. In addition, the snap-fit ​​mechanism design ensures quick switching between installation and disassembly operations, saving maintenance time and improving the overall system efficiency.

[0018] 2. The limiting mechanism, through its unique structure, precisely restricts the sliding sleeve and connecting plate, preventing misalignment or detachment during installation and disassembly. The cooperative design of the limiting sleeve and the sliding sleeve ensures the smooth sliding of the sliding sleeve within the groove. Furthermore, the interaction between the limiting block and the sliding rod ensures that the mounting plate can be precisely separated from the fixed sleeve during disassembly. The function of the limiting mechanism is to prevent interference between components through its adjustable structure, ensuring a smooth and safe disassembly process, making filter plate replacement more efficient, and effectively reducing the risk of damage caused by improper operation.

[0019] 3. The design of the reset mechanism ensures that all components can be stably returned to their initial position during disassembly. Through the cooperation of the mounting block, arc-shaped rod, compression plate, and compression spring, the reset mechanism ensures that all components can be precisely reset after the filter plate is installed, guaranteeing the effectiveness of the locking and limiting functions. Specifically, the reset mechanism uses the reverse force generated by compressing the compression spring to push the rotating sleeve to rotate, thereby driving the sliding rod and limiting block back to their original positions. This ensures that all components can be safely and reliably restored to their fixed state after installation. In practical applications, this design not only improves the ease of installation but also ensures the stability of the filter plate after installation, further enhancing the reliability and service life of the entire air conditioning fan system.

[0029] Please refer to Figures 1-5. A main electrical cabinet air conditioner fan includes a fixed plate 1, an mounting frame 2 installed on the fixed plate 1, a fan body 3 installed inside the mounting frame 2, and a mounting plate 4 installed on the outside of the fixed plate 1 via a snap-fit ​​mechanism. A filter plate 5 is fixed inside the mounting plate 4. The snap-fit ​​mechanism includes a rod 6, a fixing sleeve 7, a slot 8, an abutment plate 9, a connecting plate 10, a sliding groove 11, a sliding sleeve 12, and a limiting mechanism. The rod 6 is fixed to the outer wall of the fixed plate 1 and inserted into the mounting plate 4. The fixing sleeve 7 is inserted into the top of the rod 6. The slot 8 is located on the outer wall of the rod 6. The abutment plate 9 has multiple sets of rotating parts that rotate within the fixing sleeve 7. The inner wall, the connecting plate 10 is hinged to the bottom end of the abutment plate 9, the sliding groove 11 is provided in multiple sets distributed on the outer wall of the fixed sleeve 7, the sliding sleeve 12 slides in multiple sets of sliding grooves 11 and is hinged to multiple sets of connecting plates 10, the limiting mechanism includes limiting sleeve 13, limiting groove 14, rotating sleeve 15, sliding rod 16 and limiting block 17, the limiting sleeve 13 is fixed to the outer wall of the sliding sleeve 12, the limiting groove 14 is provided in multiple sets distributed on the outer wall of the limiting sleeve 13, the rotating sleeve 15 rotates on the outer wall of the fixed sleeve 7, the sliding rod 16 is provided in multiple sets fixed to the bottom surface of the rotating sleeve 15 and slides in multiple sets of limiting grooves 14, and the limiting block 17 is fixed to the bottom end of multiple sets of sliding rods 16.

[0030] The insertion rod 6 is polygonal, and the fixing sleeve 7 has a positioning hole 18. The positioning hole 18 is adapted to the insertion rod 6 to achieve anti-rotation fit between the insertion rod 6 and the fixing sleeve 7, thereby improving the connection stability.

[0031] Each of the multiple limiting grooves 14 has an unlocking hole 19 at one end, which provides release space when the limiting block 17 is subjected to force, so that the limiting block 17 can exit the limiting groove 14 and realize a quick unlocking operation.

[0032] The diameter of multiple unlocking holes 19 is larger than that of the limiting block 17, ensuring that the limiting block 17 can pass smoothly through the unlocking holes 19, preventing jamming and improving unlocking smoothness.

[0033] A push spring 20 is connected to the top surface of the limiting sleeve 13. A thrust bearing 21 is connected between the top end of the push spring 20 and the rotating sleeve 15 to provide continuous thrust to the rotating sleeve 15. At the same time, the thrust bearing 21 reduces rotational friction and improves the flexibility and durability of the structure.

[0034] A reset mechanism is provided on the top surface of the rotating sleeve 15. The reset mechanism includes a mounting block 22, an arc rod 23, a pressing plate 24, and a pressing spring 25. Multiple sets of mounting blocks 22 are fixed to the top surface of the rotating sleeve 15. Multiple sets of arc rods 23 are fixed to the outer wall of multiple sets of mounting blocks 22 respectively. Multiple sets of pressing plates 24 are fixed to the outer wall of the fixed sleeve 7 and are slidably connected to multiple sets of arc rods 23 respectively. Multiple sets of pressing springs 25 are provided, and their two ends are connected to the mounting blocks 22 and the pressing plates 24 respectively. The whole mechanism is used to transmit the motion generated by the rotation through the arc rods 23 to the pressing springs 25 during the structural reset process, so that each component returns to its original position, ensuring accurate and automatic reset.

[0035] Multiple sets of compression springs 25 are respectively arranged on the outside of multiple sets of arc-shaped rods 23, effectively distributing the source of elastic force and enhancing the balance and rebound efficiency of the overall reset process.

[0036] The mounting plate 4 has a socket 26, which is adapted to the plug rod 6 to achieve a tight fit between the plug rod 6 and the mounting plate 4, ensuring that the overall structure is firmly connected and easy to assemble and disassemble.

[0037] In this embodiment, the fixing plate 1 is fixed to the external air conditioner. When the filter plate 5 needs to be replaced, the rotating sleeve 15 drives multiple sets of sliding rods 16 to rotate and slide along the limiting groove 14. The rotating sleeve 15 drives multiple sets of mounting blocks 22 to push the arc rod 23 to slide along the extrusion block and compress the extrusion spring 25. When the multiple sets of sliding rods 16 slide into the unlocking hole 19, the multiple sets of limiting blocks 17 release the contact with the outer wall of the limiting sleeve 13. The push spring 20 pushes the limiting sleeve 13 to drive the sliding sleeve 12 to slide along multiple sets of sliding grooves 11, so that the sliding sleeve 12 drives multiple sets of connecting plates 10 to hinge with the abutment plate 9, thereby driving the multiple sets of abutment plates 9 to disengage from the slot 8 and release the locking of the insertion rod 6. Then the fixing sleeve 7 can be separated from the insertion rod 6, and the pressing of the fixing sleeve 7 on the mounting plate 4 can be released. The mounting plate 4 and the filter plate 5 can be disassembled by operating in sequence.

[0038] More specifically, when the filter plate 5 needs to be installed, the insertion hole 26 is inserted into the insertion rod 6, and then the fixing sleeve 7 is inserted into the top of the insertion rod 6 and its bottom end is pressed against the outer wall of the mounting plate 4. The limiting sleeve 13 is pushed to drive the sliding sleeve 12 to slide along the multiple sets of sliding grooves 11 and to compress the push spring 20. This pushes the multiple sets of connecting plates 10 to hinge with the abutment plate 9, thereby pushing the multiple sets of abutment plates 9 to engage in the slot 8. At the same time, the multiple sets of limiting blocks 17 and sliding rods 16 are inserted into the unlocking hole 19. The multiple sets of compression springs 25 are reset to push the mounting block 22 to drive the rotating sleeve 15 to rotate, thereby driving the multiple sets of sliding rods 16 to slide along the limiting groove 14, so that the multiple sets of limiting blocks 17 abut against the outer wall of the limiting sleeve 13 to limit the sliding sleeve 12.

[0039] In summary, when the entire equipment is in use or running: the fixing plate 1 is fixed to the external air conditioner. When the filter plate 5 needs to be replaced, the rotating sleeve 15 drives multiple sets of sliding rods 16 to rotate and slide along the limiting groove 14. The rotating sleeve 15 drives multiple sets of mounting blocks 22 to push the arc rod 23 to slide along the extrusion block and compress the extrusion spring 25. When the multiple sets of sliding rods 16 slide into the unlocking hole 19, the multiple sets of limiting blocks 17 release the contact with the outer wall of the limiting sleeve 13. The push spring 20 pushes the limiting sleeve 13 to drive the sliding sleeve 12 to slide along multiple sets of sliding grooves 11, so that the sliding sleeve 12 drives multiple sets of connecting plates 10 to hinge with the abutment plate 9, thereby driving the multiple sets of abutment plates 9 to disengage from the slot 8 and release the locking of the insertion rod 6. Then the fixing sleeve 7 can be separated from the insertion rod 6, and the pressing of the fixing sleeve 7 on the mounting plate 4 can be released. The mounting plate 4 and the filter plate 5 can be disassembled by operating in sequence.

[0040] When the filter plate 5 needs to be installed, the insertion hole 26 is inserted into the insertion rod 6. Then, the fixing sleeve 7 is inserted into the top of the insertion rod 6 and its bottom end is pressed against the outer wall of the mounting plate 4. The limiting sleeve 13 is pushed to drive the sliding sleeve 12 to slide along the multiple sets of sliding grooves 11 and to compress the push spring 20. This pushes the multiple sets of connecting plates 10 to hinge with the abutment plate 9, thereby pushing the multiple sets of abutment plates 9 to engage in the slot 8. At the same time, the multiple sets of limiting blocks 17 and sliding rods 16 are inserted into the unlocking hole 19. The multiple sets of compression springs 25 are reset to push the mounting block 22 to drive the rotating sleeve 15 to rotate, thereby driving the multiple sets of sliding rods 16 to slide along the limiting groove 14. This causes the multiple sets of limiting blocks 17 to abut against the outer wall of the limiting sleeve 13 to limit the sliding sleeve 12.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
