Description

Technical Field

[0001] The utility model belongs to the technical field of electronic weighing instrument preparation, and in particular relates to an electronic weighing instrument based on a bridge type weighing sensor. Background Art

[0002] Electronic scales are widely used in factories, mines, ports, warehouses, docks and other industries for weighing and measuring various materials. They mainly include electronic truck scales, electronic track scales, quantitative packaging scales, etc.

[0003] The bridge sensor is a kind of electronic truck scale. Its existing structure is as shown in announcement number CN213397294 U, which is named as a bridge sensor and a scale body, including an elastomer, a bottom beam and a base. A strain gauge is arranged in the elastomer, and a connecting layer is arranged between the elastomer and the bottom beam. The connecting layer fixes the elastomer and the bottom beam. The base is fixed to one end of the bottom beam away from the elastomer. A swing component is installed on the top of the elastomer, and the swing component is used to contact with the external scale body. A signal component for connecting the signal of the external measuring instrument is installed on the elastomer.

[0004] When using the bridge sensor, its steel ball seat is the main force-bearing part. When the force on the scale is uneven or offset, the steel ball seat will be deformed and easily worn out. The traditional steel ball seat is mainly fixed with screws, which is inconvenient to disassemble and assemble. Therefore, we proposed an electronic scale based on a bridge weighing sensor to solve the above problems. Utility Model Content

A magnetic rod is arranged inside the magnetic seat, and the magnetic seat is magnetically adsorbed and connected to the U-shaped steel ball seat through the magnetic rod. A pull-out handle is installed at one end of the magnetic rod.

[0015] Preferably, both ends of the bridge type weighing sensor are connected to the electronic scale positioning seat by bolts.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The U-shaped steel ball seat of the utility model is a double positioning structure of a clamping block and a magnetic attraction. During installation, the clamping blocks below the two ends of the U-shaped steel ball seat are engaged with the clamping grooves on the bridge type weighing sensor to achieve preliminary positioning. After positioning, the two sides of the U-shaped steel ball seat are respectively pressed against the magnetic attraction seats on both sides of the electronic scale positioning seat, and the U-shaped steel ball seat is magnetically adsorbed and fixed by the magnetic rods in the magnetic attraction seats, so as to achieve a stable connection between the U-shaped steel ball seat and the bridge type weighing sensor. When the U-shaped steel ball seat is deformed by external force, the pull-out handle at the end of the magnetic rod can be pulled outward, and the magnetic rod is separated from the U-shaped steel ball seat by applying lateral stress, so that the U-shaped steel ball seat can be conveniently removed from the bridge type weighing sensor through the force application groove, thereby solving the problem that during the use of the existing bridge type sensor, the steel ball seat is the main force-bearing part, and the steel ball seat will be deformed and easily damaged when the floor scale is subjected to uneven force or offset, and the traditional steel ball seat is mainly fixed with screws, which is inconvenient to disassemble and assemble.

[0018] The utility model provides a rubber ring on the installation through hole of the electronic scale installation base plate. After the screws are installed, the water blocking sheet can be clamped into the rubber ring. The water blocking sheet is fixed by relying on the damping elasticity of the rubber ring, which has a good waterproof effect on the screws and avoids the inconvenience of subsequent disassembly caused by corrosion caused by water.
