Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the utility model and not to limit the scope of the utility model. Moreover, in the following structures, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description. And are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation and, therefore, should not be taken to be limiting of the utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The cover plate positioning mechanism of the freezing point tester shown in fig. 1 to 5 includes a rotating shaft 300 disposed on a first contact side of the cover plate 200 and the base 100, wherein a rotating torque of the rotating shaft 300 is adjusted by press-fitting positions of first and second ball plungers 410 and 420 disposed inside the cover plate 200, specifically, first and second contact grooves 301 and 302 are disposed at the press-fitting positions of the first and second ball plungers 410 and 420 of the rotating shaft 300, and are adjusted by rotating the first and second ball plungers 410 and 420.
A positioning pin 500 is disposed on a second contact side of the cover plate 200 and the base 100, the positioning pin 500 includes a positioning seat 510 connected to the cover plate 200, and a positioning end 530 is disposed on the positioning seat 510 via a positioning rod 520. The diameter of the positioning tip 530 is larger than the diameter of the positioning rod 520.
