Description

Technical Field

[0001] The utility model relates to the technical field of fixed electronic weighing instruments, in particular to an auxiliary calibration device for weighing instruments. Background Art

[0002] Weighing instruments are widely used in industry, agriculture, commerce, scientific research, medical and health sectors. Weighing instruments use Hooke's law or the principle of lever balance to measure the mass of an object. Weighing instruments can be divided into three categories according to their structural principles: mechanical scales, electronic scales, and electromechanical combined scales.

[0003] In the prior art, common weighing scales in life, such as electronic scales, are usually placed on the ground when weighing. When the electronic scale is placed in an area with bumps and uneven ground, it may tilt, which may cause the weighing object placed on the surface to be unstable, thus affecting the weighing. Secondly, when weighing certain irregularly shaped objects, such as spherical objects, when they are placed on the electronic scale, there is a lack of auxiliary mechanisms to fix them, and they may roll or fall.

[0004] Therefore, an auxiliary calibration device for a weighing instrument is proposed to solve the above problems. Utility Model Content

[0010] As a preferred embodiment, the two grooves five are interconnected with the groove four, the two baffles two are movable inside the groove four, the carrying rod moves inside the groove three, and the surface of one end of the carrying rod moves inside another groove six.

[0011] As a preferred implementation, the baffle plate 1 moves inside the groove 2.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model places the device on a suitable platform. When the user wants to use it, the object is placed on the top of the weighing plate for weighing. The pressure sensor at the bottom of the weighing plate senses the object and transmits the data to the display terminal through the circuit inside the support frame. When the user wants to weigh irregular objects, the two interception components are clamped together to encircle the object. The structures and operations of the two interception components are the same. Only one of the operations is described here. At this time, the lever is toggled, and the lever drives the connecting shaft 2 to rotate and drive the baffle 1 to expand to a vertical state. The handle is pulled to pull the locking rod out of one of the grooves 6. At this time, the two baffles 2 are toggled to move the two baffles 2 from the inside of the grooves 6. The inside of the groove four is pulled out and spread to both sides until it is perpendicular to the baffle one, and then the locking rod is correspondingly inserted into the inside of the groove six on the opposite side for fixing, thereby completing the docking of the two interception components, so that the four baffles two and the two baffles one form a wrapped cube, at this moment, the ball object to be weighed is placed in it, and the ball object can be blocked and protected. When the weighing is completed, it is only necessary to pull the hand lever to take the locking rod out of the inside of the groove six on the opposite side, and reverse the above steps to fold and store it. This setting is convenient for enclosing objects on the surface of the scale, placing them for movement or rolling, and avoids the situation where the scale lacks an auxiliary mechanism for fixing it, which is prone to rolling or rolling, thereby improving practicality.

[0014] 2. When the utility model is used on an uneven ground, the four extension rods are rotated to extend them, and the four support legs are driven to extend downward to contact the ground for support by turning the four knobs. The setting can adjust the knob in the corresponding position of the inclined side according to the degree of potholes on the ground, so as to achieve leveling of the symmetrical weighing plate, avoiding the tilt of the electronic scale when placed in some areas with potholes and uneven ground, thereby improving practicality.
