Well known Mume flower contact is made of contact, support frame, tension spring etc., tension spring provide radial force make each contact with it is quiet
Contact closely connects, and can only control each contact radial elastic by quality (material, size) of control tension spring etc. at present
Deforming contact pressure, and can not verify whether to reach specified value.
Therefore, defect existing in the prior art is: contact elastomeric radial contact pressure can not quantitative detection.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of Mume flower contact pressure tester,
It can quantitative detection Mume flower contact contact elastomeric radial contact pressure.
The technical solution of the utility model is as follows:
A kind of Mume flower contact pressure tester, the Mume flower contact pressure tester are by pressure sensing head and operating display
Composition, the pressure sensing head are electrically connected with the operating display, and the pressure sensing head includes several for being located at head
Distribution annular in shape and mutually independent sensory package and the handle positioned at tail portion, each described sensory package correspond to plum blossom touching

The signal output end of several sensory packages is electrically connected by the amplifying circuit with the A/D conversion circuit, the A/D
The signal output end of conversion circuit connects the operating display.
Further, there are six the sensory package is set.
Further, the sensory package uses diplopore beam sensor, is integrated with foil gauge.
Further, the operating display includes display interface, interface circuit and key, the A/D conversion circuit
Signal output end is separately connected the display interface, interface circuit, key.
Further, it is connected between the pressure sensing head and operating display by conducting wire.
Compared with prior art, the utility model has the beneficial effects that: the utility model is by designing several in ring
Shape is distributed and mutually independent sensory package, each sensory package correspond to the contact of Mume flower contact, in use, pressure sensing
Head is inserted into tested Mume flower contact, and Mume flower contact is softened, in the effect of Mume flower contact contact elastomeric radial contact pressure
