Abstract
Description
Technical Field
[0001] This utility model relates to a ventilated and heat-dissipating instrument box, belonging to the field of instrument box heat dissipation technology. Background Technology
[0002] With increasing automation and the widespread use of digital instruments, instrument cases are typically provided to improve the operating environment and extend service life. Instruments generate heat during prolonged operation or in high-temperature environments. Insufficient heat dissipation can lead to decreased performance, shortened lifespan, or even malfunction. To ensure stable operation, heat dissipation structures are usually installed in the instrument case. Regular disassembly and maintenance of the filter screen is crucial for effective ventilation and heat dissipation within the instrument case, ensuring that the cooling effect remains consistently high.
[0003] For example, Chinese utility model patent CN221930401U discloses an instrument box with a ventilation and heat dissipation structure. Although the above-mentioned prior art can achieve the disassembly and maintenance of the filter, the filter is fixed inside the side plate, and the entire side plate assembly needs to be disassembled for maintenance, which is cumbersome and inefficient. Utility Model Content
[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a ventilated and heat-dissipating instrument box that facilitates the disassembly and maintenance of the filter screen.
[0005] The ventilated and heat-dissipating instrument box of this utility model includes a box body and a box door. Square slots are respectively opened on both sides of the box body. A magnetic frame is fixedly connected in the square slot. A filter screen is magnetically attracted to the magnetic frame. The box body is provided with multiple blocking pin mechanisms corresponding to the filter screen. The blocking pin mechanism includes a fixed column fixedly connected to the box body. A baffle is rotatably connected to the fixed column. A locking platform is provided at the end of the fixed column. A spring is sleeved on the outside of the fixed column between the locking platform and the baffle. A locking pin is fixedly connected to the baffle and abuts against the filter screen.
[0006] Furthermore, the end of the locking pin is rounded, and a limiting groove corresponding to the locking pin is provided on the filter screen. The diameter of the limiting groove is larger than the diameter of the locking pin. By locking the locking pin into the limiting groove, the structural stability of the filter screen after installation can be fully guaranteed.
[0007] Furthermore, the door is hinged to the box body, and a handle is installed on the door to facilitate opening and closing.
[0008] Furthermore, the bottom wall of the enclosure is provided with a cable outlet hole, which facilitates the entry and exit of cables for the instruments and equipment installed inside the enclosure.
[0009] Furthermore, a sealing gasket is provided at the edge of the filter screen, which can effectively prevent dust from entering the box and play a dustproof role.
[0010] Furthermore, the housing is equipped with a slide rail, on which a fixed frame is slidably connected. The fixed frame is used to install instruments and equipment. By sliding the fixed frame, the installation and maintenance of the instruments and equipment are facilitated.
[0011] Furthermore, the slide rail is a T-shaped rail, with transverse grooves on the rail surface and several arc-shaped recesses inside the transverse grooves, making the fixing frame more stable during sliding.
[0012] Furthermore, the fixing frame includes a vertical plate and a base plate, with the vertical plate fixedly connected to the base plate. The base plate has several fixed rails, and a hook plate is located below the base plate, positioned on the outer side of the slide rails and slidably connected to them. Several ball bearings are located on the inner side of the hook plate, engaging with transverse grooves. Several positioning bolts are located on the base plate, threadedly connected to the base plate, with their ends abutting against the slide rails. The slidable connection between the hook plate and the outer side of the slide rails, combined with the use of ball bearings, further reduces friction, ensuring smooth movement of the fixing frame on the slide rails.
[0013] The advantages of this utility model compared with the prior art are:
[0014] The ventilated and heat-dissipating instrument box of this invention forms an effective ventilation channel by opening square slots on both sides of the box and installing a filter screen and a magnetic frame. This significantly improves the airflow inside the instrument box and avoids the problem of performance degradation or damage to the instrument equipment caused by excessive temperature. The magnetic frame design not only allows for the initial positioning of the filter screen for easy installation, but also facilitates the disassembly and maintenance of the filter screen, ensuring the long-term effectiveness of the ventilation channel.
[0015] The ventilated and heat-dissipating instrument box of this utility model is equipped with a retaining pin mechanism. Through the combination of a retaining plate and a spring, the installation and removal of the filter screen becomes extremely convenient. The cooperation between the retaining pin and the limiting groove ensures the stability of the filter screen after installation, while also facilitating the disassembly and maintenance of the filter screen, effectively improving the efficiency of filter screen disassembly and maintenance.

[0028] Example 1
[0029] like Figures 1 to 10As shown, this utility model provides an instrument box with a ventilation and heat dissipation mechanism, including a box body 1 and a box door 6. The box body 1 and the box door 6 are hinged together. Square grooves 2 are respectively opened on both sides of the box body 1. A filter screen 3 and a magnet frame 5 are arranged in the square grooves 2. The magnet frame 5 is placed between the filter screen 3 and the square grooves 2. A stop pin mechanism 4 is provided on the box body 1. The stop pin mechanism 4 abuts against the filter screen 3. A slide rail 9 is provided inside the box body 1. A fixing frame 8 is provided on the slide rail 9. The fixing frame 8 is slidably connected to the slide rail 9. The slide rail 9 is a T-shaped rail. A transverse groove 91 is provided on the surface of the slide rail 9. A plurality of arc-shaped grooves 92 are provided in the transverse grooves 91. In this embodiment of the utility model, the edge part of the filter screen 3 is an iron square frame for magnetic connection with the magnet frame 5. The inside is a stainless steel mesh or a plastic mesh, which is integrally formed with the iron square frame. Specifically, in this embodiment of the invention, the magnet frame 5 can consist of several magnet blocks evenly distributed within the square groove 2 for adsorbing the filter screen 3, or it can be made into a square frame and embedded in the bottom of the square groove 2. In this embodiment of the invention, the square groove 2 is located on both sides of the housing 1, and the interior of the square groove 2 is hollowed out to hold the filter screen 3. The square groove 2 is designed as an L-shaped groove. After the magnet frame 5 is placed at the bottom, the filter screen 3 is placed there. A reinforcing platform is provided at the edge of the groove, and the reinforcing platform is flush with the edge of the filter screen 3 to facilitate the fixing of the filter screen 3 by the retaining pin mechanism 4. One end of the retaining pin mechanism 4 is fixed to the housing 1, and the other end rotates around the fixing component. When it is necessary to fix the filter screen 3, the retaining pin mechanism 4 is rotated above the filter screen 3 to restrict the movement of the filter screen 3. When replacing the filter screen, the retaining pin mechanism 4 is rotated to a direction flush with the square groove 2 to facilitate the removal of the filter screen. By creating square slots on both sides of the enclosure and installing filters and magnetic frames, an effective ventilation channel is formed, significantly improving airflow inside the instrument enclosure and preventing performance degradation or damage to the instruments due to excessive temperature. The magnetic frame design not only secures the filter but also facilitates its disassembly and cleaning, ensuring the long-term effectiveness of the ventilation channel.
[0030] The retaining pin mechanism 4 includes a baffle 41 and a fixing post 42. A locking platform 45 is provided at the end of the fixing post 42. The baffle 41 passes through the fixing post 42, and the baffle 41 is rotatably connected to the fixing post 42. The other end of the fixing post 42 is fixedly connected to the housing 1. A retaining pin 43 is provided at the other end of the baffle 41. The retaining pin 43 and the fixing post 42 are located on the same side of the baffle 41, and the retaining pin 43 abuts against the filter screen 3. A spring 44 is provided between the baffle 41 and the locking platform 45. The end of the retaining pin 43 is rounded. A limiting groove 31 is provided on the filter screen 3, and the diameter of the limiting groove 31 is larger than the diameter of the retaining pin 43. In this embodiment of the invention, the limiting groove 31 on the filter screen 3 is an arc-shaped groove, which facilitates the screwing of the retaining pin 43 in or out.
[0031] A handle 7 is provided on the cabinet door 6. The handle facilitates opening and closing the cabinet door. As a further preferred configuration, the handle 7 is a handle with a locking mechanism, enhancing the security of this invention.
[0032] Example 2
[0033] This embodiment is a further improvement based on Embodiment 1.

Square grooves 2 are respectively provided on both sides of the box body 1. A filter screen 3 and a magnet frame 5 are disposed within the square grooves 2, with the magnet frame 5 positioned between the filter screen 3 and the square grooves 2. A stop pin mechanism 4 is provided on the box body 1, abutting against the filter screen 3. A slide rail 9 is provided inside the box body 1, and a fixing frame 8 is provided on the slide rail 9, slidably connected to the slide rail 9. The T-shaped slide rail and its horizontal grooves and arc-shaped recesses inside the box body of this utility model make the fixing frame more stable during sliding, avoiding equipment displacement caused by vibration or impact, thereby improving the overall structural stability. The hook plate of the fixing frame is slidably connected to the outer side of the slide rail, and with the use of ball bearings, friction is further reduced, ensuring smooth movement of the fixing frame on the slide rail.
[0035] The slide rail 9 is a T-shaped rail, and a horizontal groove 91 is provided on the surface of the slide rail 9. Several arc-shaped grooves 92 are provided within the horizontal grooves 91. The fixing frame 8 includes a vertical plate 81 and a base plate 82. The vertical plate 81 is fixedly connected to the base plate 82. Several fixing rails 83 are provided on the base plate 82. A hook plate 84 is provided below the base plate 82, located on the outside of the slide rail 9. The hook plate 84 is slidably connected to the slide rail 9. Several ball bearings 86 are provided on the inner side of the hook plate 84, and the ball bearings 86 are engaged with the horizontal grooves 91. Several positioning bolts 85 are provided on the base plate 82, and the positioning bolts 85 are threadedly connected to the base plate 82. The ends of the positioning bolts 85 abut against the slide rail 9. In this embodiment of the invention, when the fixed frame 8 slides along the slide rail 9, the ball bearing 86 rolls within the transverse groove 91. When the ball bearing 86 rolls into the arc-shaped groove 92, it provides a damping force to the movement of the fixed frame 8, causing the fixed frame 8 to move at intervals, facilitating adjustment of the distance the fixed frame 8 moves out.
