Description

Technical Field

[0001] This utility model relates to the field of electronic weighing instrument safety protection technology, specifically to an anti-remote control device for an electronic truck scale display. Background Technology

[0002] As a terminal device for weighing data, electronic truck scale displays are susceptible to interference from illegal wireless remote control signals, which can lead to data tampering or abnormal display.

[0003] Traditional protection methods have the following problems: low heat dissipation efficiency: the monitor is prone to component aging due to heat accumulation during long-term operation (such as the capacitor bulging rate increasing by 15% per year); traditional heat dissipation hole design is prone to dust introduction, with a blockage rate of up to 30% per year; and poor installation stability: vehicle weighing vibration may cause the device to shift, resulting in loose signal interfaces and an increased risk of data interruption.

[0021] 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.

[0022] Please see Figures 1-4 This utility model discloses an anti-remote control device for an electronic truck scale display, including an equipment box 1, a display panel 2 fixedly connected to the front end of the equipment box 1, and a control button 3 fixedly connected to the bottom of the front end of the display panel 2.

[0023] Both sides of the outer wall of the equipment box 1 are fixedly connected to the fixing slot plate 4. Multiple cooling fans 10 are rotatably connected to the inner wall of the fixing slot plate 4, and a connecting plate 11 is fixedly connected to one side of each fixing slot plate 4.

[0024] Specifically, the equipment box 1 is made of double-layer cold-rolled steel plate, with the inner layer sprayed with conductive paint and the outer layer galvanized. The overall shielding effectiveness is ≥60dB, which can block 99.9% of the 2.4GHz remote control signal. The connection lines between the display panel 2 and the control button 3 are connected to the equipment box through a through-core capacitor filter with a cutoff frequency of 1GHz to prevent external signals from entering through the cable coupling. The cooling fan 10 in the fixed slot plate 4 is a dustproof centrifugal fan.

[0025] In this embodiment, rotating frames 5 are fixedly connected to both the upper and lower ends of the connecting plate 11 on both sides of the outer wall of the equipment box 1, and the number of rotating frames 5 is four.

[0026] Specifically, the four rotating frames 5 on both sides of the equipment box are arranged in a rectangular shape, and the rotating plate 6 is hinged to the rotating frame by a stainless steel shaft pin to absorb the vibration energy when the vehicle is weighed.

[0027] In this embodiment, a rotating plate 6 is rotatably connected to the inner wall of a plurality of rotating frames 5, and a spring rod 9 is fixedly connected to the end of the plurality of rotating plates 6 away from the rotating frame 5.

[0028] Specifically, the spring rod 9 at the end of the rotating plate 6 is a cylindrical helical spring. When the device is impacted, the spring rod absorbs kinetic energy to prevent the equipment box from colliding hard with the mounting surface and can withstand the acceleration impact of external forces.

[0029] In this embodiment, two spring rods 9 are fixedly connected to one side of the fixed groove plate 4.

[0030] Specifically, by fixing the spring rod 9 to one side of the fixed groove plate 4, the device can move more smoothly.

[0031] In this embodiment, a plurality of fixing rods 12 are fixedly connected to the other side of the outer wall of the connecting plate 11, and a plurality of heat-conducting pipes 13 are fixedly connected to the outer wall of the plurality of fixing rods 12.

[0032] Specifically, the heat pipe 13 on the connecting plate 11 uses copper micro heat pipes, with one end attached to the inner wall of the equipment box to absorb heat, and the other end dispersed into the air through the connecting bracket 14. Together with the cooling fan, this reduces the temperature inside the equipment box by more than 10°C.

[0033] In this embodiment, multiple connecting brackets 14 are fixedly connected between multiple heat pipes 13, and the multiple connecting brackets 14 are all located between multiple fixed rods 12.

[0034] Specifically, the heat pipe 13 is fixed by setting the connecting bracket 14.

[0035] In this embodiment, a fixing sleeve 7 is fixedly connected to the center position of multiple rotating plates 6, and a suction cup rod 8 is fixedly connected to the inner wall of multiple fixing sleeves 7.

[0036] Specifically, the suction rod 8 inside the fixed sleeve 7 is connected to a manual vacuum pump. Pressing the suction rod 8 can create a vacuum adsorption on the mounting surface. Combined with the elastic support of the spring rod, tool-free quick installation can be achieved.

[0037] The working principle and usage process of this utility model are as follows: During use, the built-in temperature sensor monitors the temperature inside the equipment box in real time. When the temperature is high, the cooling fan 10 starts and draws in cold air through the ventilation holes of the fixed slot plate 4. The hot air is guided to the top of the equipment box and discharged through the heat conduction pipe 13. When the fan rotates at high speed, the dust inside the equipment box 1 is automatically dislodged and discharged. When the car vibrates during weighing, the rotating plate 6 swings with the vibration direction, and the spring rod 9 is compressed and deformed to absorb energy, reducing the amplitude of vibration transmitted to the equipment box. Tests have shown that it can reduce vibration acceleration. During installation, press the suction cup rod 8 to expel air, and the suction cup forms a vacuum adsorption with the mounting surface. The spring rod provides pre-tightening force to ensure that the device does not shift under vibration. During disassembly, rotate the locking valve to release the vacuum and easily remove the device.
