Detailed Description
To facilitate an understanding of the utility model, the utility model will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1 and 2, the utility model provides an inertia mechanism closed overload test tool, which includes a centrifugal seat 1 and a circuit board 4 arranged on the centrifugal seat, wherein at least one mounting groove is concavely arranged on a side portion of the centrifugal seat, a mounting hole 11 for mounting an inertia mechanism is formed in a wall of the mounting groove, an electric connection plate 3 and an electric connection piece 2 are arranged in the mounting groove, the electric connection plate is inserted into the centrifugal seat through grooves on two opposite sides of the electric connection plate, one end of the electric connection piece is connected with the electric connection plate, the other end of the electric connection piece is connected with the circuit board, a power switch 7, a signal lamp 5 and an accommodating portion are arranged on the circuit board 4, and a screw plug 6 is accommodated in the accommodating portion.
In one embodiment, the number of the installation grooves is 6, and the 6 installation grooves are uniformly arranged around the periphery of the centrifugal seat.
In one embodiment, the electric connecting piece comprises a first bending part and a second bending part, the first bending part is connected with the circuit board, and the second bending part is connected with the centrifugal seat.
In one embodiment, the accommodating portion has an accommodating hole for mounting the screw plug, and the accommodating hole penetrates through two opposite sides of the accommodating portion.
In one embodiment, the circuit board is fixedly connected with the centrifugal seat through screws.
In one embodiment, the centrifuge holder is fixedly connected to the centrifuge by means of a screw thread.
In one embodiment, the power switch and the signal lamp are soldered to the circuit board.
According to the inertia mechanism closed overload test tool, the position for installing the inertia mechanism is designed on the centrifugal seat, and the 6-shot inertia mechanism can be measured at the same time. When the centrifugal machine is used, the power switch is firstly turned on, then the centrifugal machine is started, the rotating speed is adjusted, and whether the closing overload value of the inertia mechanism meets the requirement or not is judged through the signal lamp. The tool is simple and reasonable in structure, convenient to operate, high in measuring efficiency, time-saving and labor-saving.
