Description

Technical Field

[0001] This utility model belongs to the field of signal shielding technology, and in particular relates to a signal shielding device. Background Technology

[0002] Electronic signal jammers are widely used in daily life. They are mainly used to interfere with signals, thereby preventing mobile phones and other electronic communication devices from connecting to the internet. They are often used in exam rooms to prevent cheating and in meetings to prevent the leakage of information.

[0003] However, after an exam or meeting, the electronic signal jammers need to be collected for use in the next exam or meeting. However, since electronic signal jammers are usually stored in a centralized manner after use, they are prone to collisions, which can cause them to malfunction and affect their normal use. Furthermore, during the storage period, dust can easily accumulate on the surface of the electronic signal jammers or enter their interior and adhere to their internal components. When the electronic signal jammers are used again, the dust on the internal components can easily cause short circuits, thus reducing their lifespan. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] As described in the background section, electronic signal jammers need to be recycled after an exam or meeting for use in the next exam or meeting. However, since electronic signal jammers are usually stored in a centralized manner after use, they are prone to collisions, which can cause them to malfunction and affect their normal use. Furthermore, during the storage period, dust can easily accumulate on the surface of the electronic signal jammer or enter its interior and adhere to its internal components. When the electronic signal jammer is used again, the dust on the internal components can easily cause a short circuit, thereby reducing the lifespan of the electronic signal jammer.

[0024] Therefore, in order to solve the above problems, such as Figure 1 As shown, this embodiment provides a signal shielding device, including a first housing 1 and a second housing 2 hinged to the first housing 1; as Figure 3As shown, a rotatable buckle 11 is provided on the side of the first housing 1 away from the hinge joint between the first housing 1 and the second housing 2; a buckle hook 21 matching the buckle 11 is provided on the side of the second housing 2 away from the hinge joint between the first housing 1 and the second housing 2; when the buckle 11 is connected to the buckle hook 21, the interiors of the first housing 1 and the second housing 2 form a sealed space; mounting plates 3 are fixedly connected to the interiors of both the first housing 1 and the second housing 2; a shielding device 4, a storage battery 5, and a solar panel 6 are detachably connected to each mounting plate 3; the storage battery 5 is electrically connected to the shielding device 4 to supply power to the shielding device 4; the solar panel 6 is electrically connected to the storage battery 5 to charge the storage battery 5.

[0025] In situations requiring signal shielding, the buckle 11 is disengaged from the hook 21 to open the first housing 1 and the second housing 2. Once the first housing 1 and the second housing 2 are opened, the shielding device 4 is activated, and the solar panel 6 charges the battery 5. The mounting plate 3, made of ceramic, serves as both insulation and counterweight.

[0026] like Figure 3 As shown, multiple anti-slip pads 9 are evenly distributed on the outer surfaces of the first housing 1 and the second housing 2. These anti-slip pads 9 are used to contact the support surfaces that support the first housing 1 and the second housing 2 when they are fully opened. For example, when the entire signal shielding device is placed on a table, the support surface is the tabletop. The anti-slip pads 9 are made of rubber, and together with the ceramic mounting plate 3 which acts as a counterweight, the stability of the entire signal shielding device during use is improved. A connecting block 12 is provided on the side of the first housing 1; a handle 8 is rotatably connected to the connecting block 12, making it easy to grip the handle 8 to move the entire signal shielding device.

[0027] For example, such as Figure 2 As shown, both the first housing 1 and the second housing 2 have power inlets 7 on their sides; the power inlets 7 are electrically connected to the shielding device 4. When the solar panel 6 cannot charge the battery 5 (e.g., when the light intensity is insufficient), the battery 5 can be charged by plugging a power cord into the power inlet 7 and connecting it to an external power source. Power cord slots 10 are provided on the inner walls of both the first housing 1 and the second housing 2. When not in use, the power cord can be placed in the power cord slots 10 to minimize the risk of loss. Figure 4 As shown, each of the two power connection ports 7 is provided with an openable cover plate 71, which can be closed by the elastic force of the elastic element to prevent foreign objects from entering the power connection port 7.

[0028] For example, a rubber ring is provided on the opening of the first housing 1 along the circumference of the opening. After the first housing 1 and the second housing 2 are closed, the rubber ring improves the sealing performance of the first housing 1 and the second housing 2 after closure, preventing dust from entering the interior of the first housing 1 and the second housing 2, and at the same time, to a certain extent, preventing the interior of the first housing 1 and the second housing 2 from getting damp after closure, thereby protecting the internal components of the shielding device 4 from the influence of the external environment of the first housing 1 and the second housing 2 as much as possible.

[0029] For example, such as Figure 2 As shown, two first casters 13 are provided at the corner of the first housing 1 away from the handle 8; the two first casters 13 are away from the opening of the first housing 1; two second casters 22 are provided at the corner of the second housing 2 away from the handle 8; the two second casters 22 are away from the opening of the second housing 2. The casters can improve the handling efficiency and portability of the entire signal shielding device.

[0030] This utility model provides a signal shielding device that stores the shielding device 4 in a sealed space formed by a first housing 1 and a second housing 2. This prevents the shielding device 4 from malfunctioning due to impacts and ensures its normal operation. During storage, external dust is prevented from accumulating on the surface of the shielding device 4 or entering its interior and adhering to its internal components. This prevents internal short circuits caused by dust on the internal components when the shielding device 4 is used again, thus extending its service life.

[0031] The present invention has been described in detail above with reference to specific embodiments and exemplary examples; however, these descriptions should not be construed as limiting the present invention. Those skilled in the art will understand that various equivalent substitutions, modifications, or improvements can be made to the technical solutions and implementation methods of the present invention without departing from the spirit and scope of the present invention, and all such modifications and improvements fall within the scope of the present invention. The scope of protection of the present invention is defined by the appended claims.
