Description

Technical Field

[0001] The utility model relates to the technical field of signal shielding devices, in particular to a wireless signal shielding device. Background Art

[0002] A wireless signal jammer is a signal blocking device. Within a certain frequency range, the signal receiving source and the signal transmitting source cannot establish a communication connection. It is widely used in some specific places. During operation, the wireless signal jammer scans from the low-end frequency to the high-end frequency of the forward channel at a certain speed. This scanning speed can form garbled interference in the message signal received by the mobile phone, making it impossible for the mobile phone to detect the normal data sent from the base station, thereby preventing the mobile phone from establishing a connection with the base station and failing to realize the communication function.

[0003] The shell of the wireless signal jammer is usually provided with a heat dissipation mesh plate, through which the heat dissipation mesh plate is used to dissipate heat from the inside of the shell. Since airflow often flows through the heat dissipation mesh plate, dust or debris is easily accumulated. These dust or debris are easily blown into the shell with the airflow and fall on the electrical components in the shell. The heat dissipation mesh plate is mostly fixed to the shell with screws, so it is difficult to completely clean the heat dissipation mesh plate. Usually, only the outer surface of the heat dissipation mesh plate can be cleaned. Therefore, the heat dissipation mesh plate on the existing wireless jammer is easy to cause dust and impurities to enter the inside of the shell, and it is also very difficult to clean. Utility Model Content

[0004] In order to solve the above problem, that is, the heat dissipation mesh plate on the wireless shield is easy to cause dust or impurities to enter the interior thereof, the utility model proposes a wireless signal shield, which includes a shell, and heat dissipation members are installed on the wide sides of both sides of the shell, and the heat dissipation members include vertical mesh plates and inclined mesh plates arranged at equal angles, the top edges of the vertical mesh plates and the inclined mesh plates are against the upper surface inside the shell, the bottom edges of the vertical mesh plates and the inclined mesh plates are against the lower surface inside the shell, and the top edges of the vertical mesh plates are connected to the top edges of the inclined mesh plates.

[0005] The utility model is further configured as follows: the heat sink is slidably connected to the shell.

[0006] The utility model is further configured as follows: the bottom edge of the vertical mesh plate and the bottom edge of the inclined mesh plate are also connected to a bottom plate, and the bottom plate, the vertical mesh plate and the inclined mesh plate together form a cylinder with a triangular cross-section.

[0007] The utility model is further configured as follows: slide rails are arranged on the shell corresponding to the inclined mesh plate and the bottom plate, the slide rails are arranged parallel to the wide side of the shell, and slide grooves adapted to the slide rails are opened on the inclined mesh plate and the bottom plate.

[0008] The utility model is further configured as follows: two limit clamps are arranged on the front side surface of the shell, and one end of the heat sink close to the limit clamp is rotatably connected with a clamping plate adapted to the limit clamp.

[0009] The beneficial effects of the utility model are:

[0010] 1. By setting the inclined mesh plate, it is possible to achieve a blocking effect on dust and impurities. Furthermore, when dust or impurities enter from the vertical mesh plate, they will be located between the vertical mesh plate and the inclined mesh plate. Under the blocking effect of the inclined mesh plate, it can effectively prevent dust or impurities from directly entering the shell.

[0018] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] The utility model provides a wireless signal shielding device, comprising a shell 1. Installation notches are provided on the wide sides of both sides of the shell 1 for installing a heat sink 2. One end of the installation notch close to the front surface of the shell 1 is open, and one end of the installation notch close to the rear surface of the shell 1 is closed.

[0020] The heat sink 2 includes a vertical mesh plate 21, an inclined mesh plate 22 and a bottom plate 23, which together form a cylinder with a triangular cross-section, that is, the vertical mesh plate 21 and the bottom plate 23 are vertically arranged, and the adjacent edges of the vertical mesh plate 21, the inclined mesh plate 22 and the bottom plate 23 are welded to each other, that is, the top edge of the vertical mesh plate 21 is welded to the top edge of the inclined mesh plate 22, the bottom edge of the vertical mesh plate 21 is welded to one of the long edges of the bottom plate 23, and the bottom edge of the inclined mesh plate 22 is welded to the other long edge of the bottom plate 23.

[0021] The top edges of the vertical mesh plates 21 and the inclined mesh plates 22 abut against the upper surface inside the shell 1, and the bottom edges of the vertical mesh plates 21 and the inclined mesh plates 22 abut against the lower surface inside the shell 1, so that the installation gap on the shell 1 can be blocked by the cooperation of the vertical mesh plates 21 and the inclined mesh plates 22.

[0022] Through the cooperation of the vertical mesh plate 21 and the inclined mesh plate 22, the heat dissipation function inside the shell 1 can be achieved. At the same time, when dust or impurities pass through the mesh holes on the vertical mesh plate 21, the dust or impurities will be located between the vertical mesh plate 21 and the inclined mesh plate 22. At this time, under the blocking effect of the inclined mesh plate 22, dust or impurities will not easily pass through the inclined mesh plate 22, thereby effectively preventing dust or impurities from entering the inside of the shell 1.

[0023] The heat sink 2 is slidably connected to the shell 1, and two slide rails 11 are welded in the installation notch, one of the slide rails 11 is arranged corresponding to the inclined mesh plate 22, and the other slide rail 11 is arranged corresponding to the bottom plate 23. The slide rail 11 is an angle plate with an "L"-shaped cross-section. The inclined mesh plate 22 and the bottom plate 23 are both provided with slide grooves 24 through a bending process, and the slide grooves 24 are adapted to the slide rails 11. The heat sink 2 is slidably connected to the shell 1 through the slide grooves 24 and the slide rails 11, thereby achieving the purpose of quickly disassembling and assembling the heat sink 2, so that the heat sink 2 can be disassembled for thorough cleaning.

[0024] Two limit clips 12 are welded on the front surface of the shell 1, and the opening of the limit clip 12 is set upward. One end of the heat sink 2 close to the limit clip 12 is rotatably connected with a clamping plate 25, and the clamping plate 25 is adapted to the limit clip 12, that is, the clamping plate 25 can be rotated into the limit clip 12 and cooperate with the limit clip 12 to realize the limiting effect on the sliding of the heat sink 2.

[0025] In summary, the utility model can achieve the function of blocking dust and impurities by setting the inclined mesh plate 22. Further, when dust or impurities enter from the vertical mesh plate 21, they will be located between the vertical mesh plate 21 and the inclined mesh plate 22. Under the blocking effect of the inclined mesh plate 22, dust or impurities can be effectively prevented from directly entering the housing 1. Through the cooperation of the slide rail 11 and the slide groove 24, the detachable function of the heat sink 2 can be achieved, and the disassembly process is simple and convenient, so that the heat sink 2 can be disassembled and cleaned, so that it can be cleaned more thoroughly.
