Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a pull plate sensor. Background Art

[0002] When a truck is tying up cargo, there are too many straps that need to be interlaced and many straps need to cross each other to bear force. However, sometimes a certain section of the strap may be subjected to force in multiple directions, resulting in uneven force when the strap is tied. It is possible that a certain section of the strap is not subjected to force. The characteristics of the rope make it impossible to intuitively observe whether the rope is subjected to force, and the reliability of the binding cannot be guaranteed. Therefore, a pull plate sensor is proposed to solve the above problems. Utility Model Content

One end of the elastomer is arranged in a "Y" shape, which can be assembled with the binding beam or the universal rotating wheel on the load-carrying truck to ensure that the sensor can rotate 360° and that the direction of the binding strap can be changed at will during binding. The other end of the elastomer is connected to the universal rotating ring, and the indicator light and aviation plug are both installed on the top of the elastomer, and the aviation plug is connected to a cable.

[0005] Preferably, a sealing sheet and a strain gauge are provided on the elastomer, and the sealing sheet is coated with silicone. This silicone has a wide operating temperature range and can meet the operating environment requirements of the sensor at -20°C to +80°C, while meeting the requirements of protection grade IP65; the base of the strain gauge is constantan material, which can make the pressure strain gauge stably used at room temperature and have good insulation, ductility and flexibility, and can be completely fitted to the strain part of the elastomer, with the best overall comprehensive performance. After the insulating protective material is applied, the sensor is pasted, which improves the accuracy and reliability of the sensor detection and avoids interference with the reading.

[0006] Preferably, the aviation plug is provided with a CAN protocol transmitter module, and the CAN protocol transmitter module is connected to the main control console through the transmission line of the aviation plug. The CAN protocol transmitter module is specially designed and has an operating temperature of -35°C to +85°C. The transmission of the CAN protocol transmitter module can be connected to a bus of the main control console and ensure that instructions are sent to different sensors respectively, ensuring that the transmission line is concise, clear, beautiful and generous. Data is transmitted to the main control console through the CAN bus, and the force value can be monitored and displayed in real time. There is a command in the CAN protocol, and the indicator light can be controlled by sending a command.

[0007] Preferably, the elastic body and the universal rotating ring are connected via a pin.

[0008] Preferably, the bottom end of the universal rotating lifting ring is screwed into the binding plane of the truck.

[0009] Preferably, the outer wall fixing sleeve of the elastic body is provided with a protective sleeve, and the protective sleeve is made of rubber material.

[0010] Preferably, the protective cover is provided with through holes adapted to the indicator light and the aviation plug, respectively, and the indicator light and the aviation plug are respectively located in the corresponding through holes.
