Description

Technical Field

[0001] The utility model relates to the field of potentiometers, in particular to a balanced potential difference guarantee device. Background Art

[0002] The potentiometer is an instrument constructed using the compensation principle. In order to ensure the measurement accuracy of the potentiometer, precision detection equipment is generally used to detect the potentiometer. The potentiometer precision detection equipment in the prior art is generally composed of a box, a standard battery installed inside the box, a galvanometer, a sliding rheostat, a single-pole single-throw switch and other components, and a mounting plate for fixing the box. When in use, first turn on the switch, then adjust the resistance of the sliding rheostat, and then detect the precision of the potentiometer based on the principle of mutual compensation between the measured voltage and the known voltage. However, when adjusting the use direction of the existing potentiometer precision detection equipment, it is necessary to hold the box and the mounting plate with both hands and rotate them together to adjust the use direction. The use direction of the potentiometer precision detection equipment cannot be adjusted by rotating only the box.

[0003] According to the published patent 202320202893.2, a potentiometer precision detection device includes an installation box for installing the potentiometer precision detection device body, the middle part of the lower end surface of the installation box is recessed downward to form a placement groove, a mounting plate is arranged on the lower side of the installation box, a support column is arranged in the middle part of the upper end of the installation plate, a circular plate is arranged on the upper end of the support column, a plurality of baffles arranged in a ring shape are arranged on the lower end of the circular plate, two connecting rods with a symmetrical structure are arranged on the inner wall of the placement groove, and the connecting rods are located between two adjacent baffles, the lower end surface of the installation box is recessed upward to form an annular slide groove, and the The upper end of the mounting plate is provided with two symmetrical cylinders, the inner wall of the cylinder is slidably connected with a piston, the upper end of the piston is provided with a movable rod and the movable rod extends to the upper side of the cylinder and is slidably connected to the inner wall of the annular slide groove. This design achieves the purpose of flexible use of the potentiometer precision detection equipment. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the movable rod is driven downward by pressing the mounting box downward, the downward movement of the movable rod will drive the piston to slide downward along the inner wall of the cylinder, and the downward sliding of the piston will increase the air pressure on the lower side of the piston. At the same time, the mounting box is pushed downward. The downward movement will drive the connecting rod to move downward to the lower side of the baffle, and then rotate the installation box to adjust the rotation direction of the installation box. After adjusting the direction of the installation box, release the installation box. Under the action of the air pressure on the lower side of the piston, the piston will move upward and drive the movable rod to move upward. The upward movement of the movable rod will drive the installation box and the connecting rod to move upward. When the connecting rod moves upward to a suitable position, it will fit with the lower end of the circular plate. At this time, the connecting rod will be located between two adjacent baffles. The two adjacent baffles will limit the connecting rod, thereby improving the stability of the potentiometer precision detection equipment and achieving flexible control of the potentiometer precision detection equipment. The purpose of use is to solve the problem that the existing potentiometer precision detection equipment needs to adjust the use direction by holding the box and the mounting plate with both hands to rotate together to adjust the use direction, and the use direction of the potentiometer precision detection equipment cannot be adjusted by rotating the box alone. However, during use, the traditional balanced potential difference guarantee equipment needs to use a piston inflation method to drive the potentiometer precision detection equipment in the installation box to adjust the position. This method has a relatively single adjustable angle for the potentiometer precision detection equipment, and cannot adjust the potentiometer precision detection equipment at multiple positions and angles. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a balanced potential difference guarantee device to solve the current traditional balanced potential difference guarantee device, which needs to adopt a piston inflation method to drive the potentiometer precision detection device in the installation box to adjust the position. This method has a relatively single adjustable angle for the potentiometer precision detection device and cannot adjust the potentiometer precision detection device at multiple positions and angles. Technical problems.
