Embodiment Construction

[0020] like figure 1 As shown, the small object tester described herein includes two symmetrical semi-cylindrical structures 11 , 12 , a solid structure 14 on a slope surface, electromagnet units 15 , 16 , a rotating shaft device 17 and a control unit 18 . The slope surface solid structure 14 is inside the two symmetrical semi-cylindrical structures 11, 12, and the semi-cylindrical devices 11, 12 are closely attached to the slope surface solid structure 14 when closed, and the electromagnet units 15, 16 are installed in the semi-cylindrical structures The edges of the outer openings of 11 and 12 are symmetrically distributed, and the control unit 18 controls the polarity of the electromagnet units 15 and 16 to control the opening and closing of the two symmetrical semi-cylindrical structures 11 and 12 . Because the polarity of the electromagnet is determined by the winding direction of the coil and the direction of the current, when the winding direction of the coil is fixed, ...

Abstract

The invention discloses a small part tester which comprises a cylinder device, a slope solid structure, a rotating shaft device, electromagnet units and a control unit, wherein the slope solid structure is arranged in the cylinder device, the cylinder device consists of two separated half cylinders, one side of one half cylinder is connected with one side of the other half cylinder by a rotating shaft device, the electromagnet units for controlling the opening and closing of the two half cylinders are respectively arranged at the opening parts of the other sides of the two half cylinders, and a door structure is formed by the electromagnet units and the cylinder device, and the control unit is positioned outside the cylinder device and connected with the electromagnet units to control the polarities of the electromagnet units. According to the small part tester, due to the improvement of a traditional small part tester, parts to be tested in the small part tester with the door structure can be conveniently taken out.

Description

technical field [0001] The invention belongs to the field of experimental instruments and relates to a small object tester with side openings. Background technique [0002] The small object tester is a device used to simulate the throat of a child under 3 years old, and to assess whether the toy has the risk of choking caused by children swallowing objects after use and reasonable abuse. [0003] The traditional small object tester is a cylindrical device that imitates the throat of children under 3 years old. During the experiment, under the condition of no external pressure, test samples with disassembled or falling parts on toys played by children under 3 years old If it can be completely contained in the test cup at any angle by its own weight, the part is judged as a small object, otherwise it is not a small object. If it passes through this part, it is regarded as a small object. [0004] There is no mechanical opening on the side of the traditional small object teste...
