Description

Technical Field

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

[0002] A weighing sensor is a device that converts mass signals into measurable electrical signal outputs. However, the existing bridge-type weighing sensors have poor shock absorption effects. When the weighing device vibrates, the impact of the vibration can cause the detection element to move, resulting in measurement errors.

[0003] The prior art patent CN213021914U discloses a bridge-type weighing sensor. When in use, people can twist the second bolt through the handle, and the second bolt will drive the support plate to move up and down through the second through hole and the second threaded groove. The elastic force of the spring can make the support plate and the support block elastic. When the weighing device vibrates, the elastic force of the spring can reduce the vibration of the first box body through the support plate, thereby achieving the first-level shock absorption effect. At the same time, the shock-absorbing pad can reduce the vibration of the support block and reduce the vibration of the weighing device, thereby achieving the second-level shock absorption effect, thereby achieving the purpose of good shock absorption effect. When the weighing device vibrates, the shock-absorbing structure can reduce the movement of the detection element and reduce the measurement error, thereby improving the accuracy of the detection result.

[0004] However, in the above-mentioned prior art, when a user places an object on the bridge type weighing sensor, if the placing force is too great, the bridge type weighing sensor may be damaged, and shock absorption alone cannot avoid the impact of the user placing the object. Utility Model Content

The two sliders are respectively slidably connected to the corresponding electric slide rails. The two clamping units are respectively arranged below the corresponding sliders, and the placement groove is arranged between the two clamping units.

[0008] Wherein, the weighing assembly further comprises a buffer pad, the buffer pad is fixedly connected to the base and is located above the base, and the bridge type weighing sensor is placed above the buffer pad.

[0009] Wherein, the clamping unit includes a first cylinder, a second cylinder and a limit block, the first cylinder is fixedly connected to the slider and is located below the slider, the second cylinder is fixedly connected to the output end of the first cylinder, and the output end of the second cylinder is fixedly connected to the limit block, and the placement groove has two limit grooves, and the two limit grooves are respectively adapted to the corresponding limit blocks.

[0010] Wherein, the bridge type weighing sensor also includes an auxiliary component, and the auxiliary component is arranged on the base.

[0011] Wherein, the auxiliary component includes a support column and a plurality of moving wheels, the support column is fixedly connected to the base, and the plurality of moving wheels are fixedly connected to the base and are distributed in sequence below the base.
