Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a position limiting protection device for a large-scale weighing instrument sensor. Background Art

[0002] Large scale sensors are sensor devices used to measure the weight of large objects. They are commonly used in industrial applications such as lifting equipment, cranes, and cargo weighing. These sensors detect and measure the mass of suspended objects, ensuring safe operation and accurate measurement. These sensors typically transmit this information to a display or recording system for user viewing and recording. Large scale sensors utilize various mechanisms to limit their position, but these limit devices are complex, cumbersome, and time-consuming and labor-intensive to install and remove.

[0003] A Chinese patent discloses a limit protection device for a large-scale weighing instrument sensor (authorization announcement number CN220960292U). The patented technology mainly includes a mounting base plate, the upper surface of which is fixedly connected to two vertical plates, the upper surfaces of which are jointly fixedly connected to a support plate, a limit hole is provided on the upper surface of the support plate, and a sensor pressure head is provided inside the limit hole. The gap between the sensor pressure head and the limit hole is three millimeters. A bearing platform is provided above the support plate. The sensor mounting groove and the second mounting hole are provided to install and fix the main body of the weighing instrument sensor. The vertical plate, support plate, limit hole, slide rail bracket, track wood and limit bolt are provided to clamp and limit the bearing platform and the sensor pressure head. The support and cooperation with the limit support block and protective pad effectively prevent the bearing platform from tipping over, avoid crushing the sensor body, and facilitate the safe use of large-scale weighing instrument sensors.

[0004] However, this patent still has some shortcomings. When limiting the position of a large scale sensor, multiple devices are used to limit the position of the large scale sensor. However, the limiting devices are complex in structure, complicated in operation, and time-consuming and labor-intensive to install and remove. Therefore, those skilled in the art have provided a large scale sensor limit protection device to solve the problems raised in the above background technology. Utility Model Content
