Description

Technical Field

[0001] This utility model relates to the field of wireless radio frequency testing equipment, and specifically discloses a wireless radio frequency conformance testing shielding box. Background Technology

[0002] Wireless radio frequency (RF) test equipment is a professional instrument used to test and evaluate the performance, functionality, and compatibility of wireless radio frequency (RF) related products, components, or systems. It is mainly used to measure various parameters of wireless RF signals, such as frequency, power, modulation method, bandwidth, signal-to-noise ratio, and transmit / receive performance, to ensure that the equipment meets technical standards and design requirements during wireless communication. RF test equipment is an indispensable link in the wireless communication industry chain, and its technological advancements directly promote the development of fields such as 5G, the Internet of Things, and satellite communication, ensuring that various wireless devices work stably in complex electromagnetic environments.

[0003] In the production and R&D of wireless radio frequency products, conformance testing is required to ensure that the product performance meets the standards. Since external electromagnetic interference can seriously affect the test results, shielding boxes are usually used to isolate external electromagnetic signals. However, the heat dissipation effect inside the current shielding boxes is not good. During long-term testing, the heat generated by the equipment cannot be dissipated in time, which will affect the performance of the equipment and is not conducive to its current use. To address this issue, we propose a wireless radio frequency conformance testing shielding box to solve the above problems. Utility Model Content

[0011] The beneficial effects of this utility model are:

[0012] This wireless radio frequency conformance testing shielded box uses a fan and suction pipe to create negative pressure inside the casing, which facilitates air entry through the inlet. The filter design effectively filters dust and particulate matter from the air.

Unless otherwise specified, the methods used in the present utility model are conventional methods; unless otherwise specified, the raw materials and apparatus used are conventional commercially available products.

[0020] Please see Figure 1-4 A wireless radio frequency conformance testing shielded box includes a box body 8. A partition 11 is connected to the inner side wall of the box body 8. Two nozzles 15 are connected to the inner side wall of the box body 8. A fan 12 is connected to the upper surface of the partition 11. The output end of the fan 12 passes through the partition 11 and extends to the bottom of the partition 11. A three-way pipe 13 is connected to the output end of the fan 12. Both output ends of the three-way pipe 13 are connected to bends 14. One end of each bend 14 is connected to the upper surface of the nozzle 15. A shell 4 is provided on the right side of the box body 8. A suction pipe 5 is connected to the input end of the fan 12. One end of the suction pipe 5 passes through the box body 8 and is connected to the upper surface of the shell 4. A filter screen 16 is connected to the inner side wall of the shell 4. A shielding door 1 is hinged to the front of the box body 8. Two openings 19 are opened on the bottom surface of the shell 4.

[0021] In this embodiment: the combined use of the fan 12 and the suction pipe 5 facilitates the generation of negative pressure inside the housing 4, which in turn facilitates the entry of air through the port 19. The design of the filter screen 16 facilitates the filtration of dust and particulate matter in the air. At the same time, the design of the fan 12, the three-way pipe 13 and the bend pipe 14 facilitates the discharge of gas into the nozzle 15, and then the gas is discharged outward through the nozzle 15. This also helps to dissipate heat and cool down the inside of the housing 8, thereby solving the problem of heat affecting the performance of the equipment.

[0022] As a technical optimization of this utility model, the bottom surface of the box 8 is connected to the base 2, the bottom surface of the base 2 is connected to two anti-slip plates 3, the front surface of the box 8 is embedded with a temperature sensor 7, the right side of the box 8 is connected to a controller 6, the bottom surface of the shell 4 is embedded with a rolling bearing 18, the inner ring of the rolling bearing 18 is connected to a connecting rod 17, and the top end of the connecting rod 17 is connected to a cleaning brush 20.

[0023] In this embodiment: the design of the base 2 and the anti-slip plate 3 is used to increase the stability of the device; the design of the controller 6 and the temperature sensor 7 is used to automatically control the start of the fan 12 after detecting high temperature; and the cooperation of the connecting rod 17 and the unblocking brush 20 is used to facilitate the unblocking of the filter screen 16, thereby facilitating the passage of air through the filter screen 16.

[0024] As a technical optimization of this utility model, a display panel 9 is provided in front of the shielding door 1, and the back of the display panel 9 is connected to the front of the shielding door 1. A box 10 is provided on the left side of the box body 8, and the right side of the box 10 is connected to the left side of the box body 8.

[0025] In this embodiment: the display board 9 is used to facilitate the display of the operation process of the device, and the box 10 is used to facilitate the storage of maintenance tools.

[0026] The working principle and usage process of this utility model are as follows: In use, the suction force of the fan 12 is first used to draw air into the suction pipe 5, and the dust in the air is filtered through the filter screen 16. Then, the fan 12 uses the three-way pipe 13 to transport the gas, and through the design of the bend pipe 14, the gas is discharged into the nozzle 15. At this time, the nozzle 15 discharges gas outward and achieves the purpose of heat dissipation and cooling. Then, rotating the connecting rod 17 can drive the cleaning brush 20 to clean the filter screen 16, thereby facilitating the air to pass through the filter screen 16. The housing 8 and the shielding door 1 of this device are coated with a shielding coating, thereby achieving the shielding function.
