Such shielding tents have the advantages of good mobility, light weight, and easy portability.

[0003] The existing patent (publication number: CN116163581A) discloses an electromagnetic shielding tent, which is composed of a front tent component and a rear tent component with electromagnetic shielding functions. The connection between the front tent component and the rear tent component is covered by a shielding component to achieve a good electromagnetic shielding effect. The combination of the front tent component and the rear tent component increases the area of the electromagnetic shielding tent, does not increase the sewing difficulty of the tent body, and can meet the needs of multiple people for classified office work. At the same time, it makes the erection and disassembly of the electromagnetic shielding tent simpler and more convenient, thereby effectively reducing the erection cost and difficulty of the electromagnetic shielding tent. In the process of implementing this solution, it is found that the following problems in the prior art have not been well solved:

[0004] During the use of this tent, more people can work by increasing the area. However, in order to ensure the sealing performance, the tent is often in a sealed state. The combination of multiple people working and the heat dissipation of electronic devices often leads to a relatively stuffy state inside the tent for a long time. The characteristics of the electromagnetic tent itself determine that heat cannot be dissipated directly through openings, otherwise the shielding effect is likely to be reduced. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-4 drawings.

[0029] Please refer to the drawings in the specification Figures 1-4, An embodiment provided by the present utility model: An electromagnetic shielding tent, including a tent surface main body 1, the tent surface main body 1 is composed of three layers of electromagnetic shielding fabrics, achieving shielding effect through the electromagnetic shielding fabrics to prevent signal transmission. At the connection between the tent surface main body 1 and other tent surface main bodies 1, a shielding component is provided (the same as the shielding component 4 disclosed in an electromagnetic shielding tent disclosed in the comparative document CN116163581A, which is prior art). By using the shielding component, the tent surface main body 1 can be spliced to adapt to multiple people for work. Inside the tent surface main body 1, a support frame 2 is connected, above the support frame 2, a storage block 3 is connected. The storage block 3 protects the micro motor 14 to prevent it from being damaged during transportation. Inside the storage block 3, a micro motor 14 is connected, above the micro motor 14, a driving rod 15 is connected. By driving the driving rod 15, the rotating rod 5 is driven to rotate to achieve the ventilation work;

[0030] Above the driving rod 15, a rotating rod 5 is connected. On the outer side below the rotating rod 5, a second fan blade 13 is connected. By using the second fan blade 13, the air circulation effect is enhanced to ensure use. At the top of the rotating rod 5, a first fan blade 4 is connected. At the center of the rotating rod 5, a reciprocating lead screw 6 is connected. By using the reciprocating lead screw 6, the linkage block 7 is driven to lift and lower to complete heat dissipation. On the outer side of the reciprocating lead screw 6, a linkage block 7 is connected. Below the linkage block 7, a limiting rod 11 is connected. Storage grooves 9 are provided around the linkage block 7. By cooperating the storage grooves 9 with the ventilation openings 10, the internal and external air is replaced, and it is ensured that it is always in a sealed state. On the outer side of the storage grooves 9, ventilation openings 10 are provided. The linkage block 7 is located inside the fixed block 12.

[0031] Refer to the accompanying drawings of the specification Figures 1-4 , The support frame 2 and the fixed block 12 are integrally installed. The support frame 2 and the storage block 3 are integrally installed. The support frames 2 are evenly and equidistantly distributed inside the tent surface main body 1. By the support frames 2, the storage block 3 and the fixed block 12 are respectively fixed to avoid affecting the rotation of the second fan blade 13.

[0032] Refer to the accompanying drawings of the specification Figures 1-4 , The first fan blade 4 and the rotating rod 5 are integrally rotated. The rotating rod 5 and the second fan blade 13 are integrally rotated. Above the rotating rod 5, a rain shield 8 is also connected. The rain shield 8 is made of the same material as the tent surface main body 1. The first fan blade 4 drives the rotating rod 5 and the second fan blade 13 to rotate, facilitating the subsequent heat dissipation work.

[0033] Refer to the accompanying drawings of the specification Figures 1-4 , Below the rotating rod 5, a ratchet is connected, and the connection mode between the ratchet and the pawl is meshing connection, and the connection mode between the pawl and the driving rod 15 is hot melt connection. The driving rod 15 and the micro motor 14 are integrally installed. The ratchet and pawl group enables the driving rod 15 to drive the rotating rod 5 to rotate, thus realizing a dual driving mode.

[0034] Refer to the attached drawings of the specification Figures 1-4 , the reciprocating lead screw 6 is connected to the linkage block 7 by a threaded connection, the linkage block 7 is connected to the limiting rod 11 by a sliding connection, and the limiting rod 11 is connected to the fixed block 12 by a thermal fusion connection. The reciprocating lead screw 6 drives the linkage block 7 to move up and down, so that it is always in a sealed state during the heat dissipation process.

[0035] Refer to the attached drawings of the specification Figures 1-4 , receiving grooves 9 are evenly distributed at equal distances around the center of the linkage block 7. The width quantity of the receiving grooves 9 is the same as that of the ventilation openings 10. The ventilation openings 10 are evenly distributed at equal distances on both sides of the fixed block 12. The receiving grooves 9 at the center of the linkage block 7 drive the air to exchange through the ventilation openings 10, so as to achieve the purpose of heat dissipation and improve comfort.

[0036] Working principle: When in use, first, in the case of strong natural wind, the natural wind drives the first fan blade 4 to rotate, so that the first fan blade 4 drives the rotating rod 5 to rotate, and thus the reciprocating lead screw 6 rotates together. At the same time, a threaded movement occurs with the linkage block 7. Under the limitation of the limiting rod 11, the linkage block 7 starts to move up and down. When the linkage block 7 is at the bottom, since the second fan blade 13 and the first fan blade 4 have a coaxial rotation structure, the second fan blade 13 drives the air to flow. The air enters the interior of the receiving groove 9 through the ventilation opening 10. After the linkage block 7 rises, the air inside the receiving groove 9 is replaced with the air outside the tent body 1. At this time, the bottom of the linkage block 7 blocks the ventilation opening 10 to ensure sealing. When the linkage block 7 resets, the outside air is brought into the interior of the tent body 1 by the receiving groove 9 through the ventilation opening 10 to complete the heat dissipation work;

[0037] Similarly to the above, when there is no wind, turn on the switch of the micro motor 14, which drives the driving rod 15 to rotate. The driving rod 15 drives the ratchet to rotate through the pawl, so that the rotating rod 5 above the ratchet also starts to rotate. Thus, the reciprocating lead screw 6 also starts to have a threaded movement with the linkage block 7, and the above work is repeated. The micro motor 14 can be designed with a wireless charging or wired direct connection mode according to the actual situation.

[0038] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
