Multimeter which has function of reinforcing contact and is convenient to place

Abstract

The invention relates to a multimeter which has the function of reinforcing a contact and is convenient to place. The multimeter comprises a main body, a display screen, at least two control keys, contact interfaces of at least two probes and at least two supporting blocks, and further comprises a connecting mechanism, a reinforcing mechanism and a center control mechanism. The connecting mechanism comprises a limiting rod, an adsorbing assembly, two first connecting rods, two first springs, two sleeves and two driving assemblies. A first reinforcing assembly comprises a base, a push plate, two second springs, two third springs and two bead screws. A second reinforcing assembly comprises a supporting unit, two rotary rods and two clamping blocks. By means of the multimeter which has the function of reinforcing the contact and is convenient to place, through the connecting mechanism, the multimeter can be firmly adsorbed on the surface of an object, and the probability that the multimeter falls off due to collision is lowered; through the reinforcing mechanism, the connecting firmness of the contacts of the probes and the contact interfaces of the probes can be improved, and thus the detecting accuracy of the multimeter is improved.

Description

technical field [0001] The invention relates to the field of electronic detection equipment, in particular to an easy-to-place multimeter with joint reinforcement function. Background technique [0002] Multimeters are also known as multiplex meters, multimeters, three-purpose meters, multimeters, etc. Generally, the main purpose is to measure voltage, current and resistance. Multimeters are divided into pointer multimeters and digital multimeters according to the display mode. It is a multi-functional, Multi-range measuring instruments, general multimeters can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, etc., and some can also measure AC current, capacitance, inductance and some parameters of semiconductors.

[0003] As a kind of electronic testing equipment, multimeter is an indispensable testing instrument for power electronics and other departments. Generally, when people test electronic circuits, they may need to use multiple multimeters at a time, and people often stack multimeters on top of each other for easy operation. Together, if the multimeters stacked together are collided by people, it will cause the multimeter to slip, which will bring huge losses to people. Not only that, but the joints of the test leads of the general multimeter will be plugged and unplugged for a long time. The connection with the interface on the multimeter is loose, which reduces the measurement accuracy of the multimeter
