A load cell protection structure

Abstract

The invention provides a load cell protection structure, which belongs to the field of weighing instruments and is used for connecting a load cell, including a first connecting rod, a second connecting rod and a first rebound assembly; the first connecting rod is used for connecting the weighing sensor Heavy sensor; one end of the first connecting rod and one end of the second connecting rod are connected through a ten-byte connection; the outer side of the first connecting rod is fixedly provided with a mounting frame, and the mounting frame extends toward the direction of the second connecting rod, and the mounting frame can be used The space between the first connecting rod and the second connecting rod is clamped; the end of the mounting bracket close to the second connecting rod forms a first opening for the second connecting rod to rotate out of the clamping space relative to the first connecting rod; the first The rebound assembly is installed on one side of the first opening of the installation frame, the first rebound assembly includes a first rebound plate, and when the first rebound plate is in contact with the second connecting rod, the second connecting rod always has a clamping space Movement trend of internal displacement. It has the advantages of simple assembly process, no need to use special tooling, and improved production efficiency.

Description

technical field [0001] The invention relates to the field of weighing instruments, in particular to a load cell protection structure. Background technique [0002] The load cell is a device that converts the quality signal into a measurable electrical signal output. Based on this working principle, the load cell is very sensitive to external force. If the external force exceeds the maximum load of the sensor, it will cause weighing failure. allow. [0003] Existing technical scheme one: [0004] Arm-mounted electronic scales, such as figure 1 As shown, it is mainly composed of an electronic scale arm 001 and a load cell 010, and the end of the electronic scale arm 001 is used to carry a plasma collection bottle 002 or a plasma collection bag. [0005] Because the electronic scale arm 001 is longer. If you accidentally press the electronic scale arm 001 during the operation of hanging the plasma collection bottle 002 or the plasma collection bag, a large torque will be tr...

Problems solved by technology

[0008] However, in order to keep the strut 070 in a vertical state, the strong spring 003 required is relatively strong. During production and assembly, it is assembled against the spring force, which leads to inconvenience in production; at the same time, it is difficult to keep the two end faces of the large spring horizontal, resulting in the strut not being able to maintain a vertical state.
