The utility model content

The purpose of this utility model is at the deficiencies in the prior art, and the electronic digital display Shore durometer that a kind of structure is simple, cost is lower, measuring accuracy is higher, easy to operate is provided.

The purpose of this utility model is to realize by following technical scheme:

A kind of electronic digital display Shore durometer, comprise mechanical body and capacitive grid numeral display assembly, unlike the prior art be: the capacitive grid numeral display assembly is arranged on the front of mechanical body, and the surface-mounted integrated circuit in the capacitive grid numeral display assembly and the fixed grid that is arranged in the mechanical body slidably are abutted against.

Described capacitive grid numeral display assembly is made up of shell, luffer boards, display screen, bus, operating key and surface-mounted integrated circuit, the display screen setting in the enclosure, be connected with the surface-mounted integrated circuit that is arranged on the shell bottom surface by bus, luffer boards are arranged on the window that case surface is provided with, corresponding with display screen, it is corresponding with the contact of surface-mounted integrated circuit that operating key is arranged on case surface.

Described mechanical body is made up of pressing, pressure foot, main body, steel ball, fixed grid base, gathering sill, fixed grid, pressure spring, holding screw and upper guide bush, fixed grid is fitted on the fixed grid base, fixed grid base and gathering sill are slidingly connected, gathering sill is packed in the main body, presses foot to be fitted in bottom in the main body, and pressing is fitted in presses in the foot, upper guide bush is arranged in the through hole of main body upper end, holding screw is arranged in the upper guide bush, is connected with fixed grid base by pressure spring, and fixed grid base is abutted against by steel ball and pressing.

Described steel ball is arranged in the hole of pressing upper end, and is fastening by interference fit, and an outstanding part is outside the hole.

Described upper guide bush upper end is provided with the upper guide bush lid.

Principle of work of the present utility model is: high precision capacitive displacement transducer measuring system is a mixed signal large scale integrated circuit (LSI), its function is the variation that mechanical motion is converted to electrical signal phase, by detecting different phase places, distance also shows the precise length that output is measured as calculated then.

The utility model realizes that according to this principle the numerical value of measuring shows that the pressing stroke of existing national standard Shore durometer is 2.5mm, and this scleroscopic demonstration range is 100 unit values, promptly whenever walks 0.01mm and then shows 0.4 unit value (existing national standard).By the pitch of capacitor grid transducer is changed into 5.0mm from 1 times of 5.08mm, at this moment the demonstration of holding grid shows 1mm from original mobile 1mm, become mobile 1mm and show 1.016mm, when thereby just being arranged, mobile 2.5mm shows 2.54mm, unit conversion by measuring system, it is converted to English system be shown as 0.1inch, show 100 stiffness units values in the time of just can realizing mobile 2.5mm by the driving demonstration of changing display screen again.

The utility model can be widely used in soft rubber, plastics, PVC, polyester, neoprene, leather, thiokol, tire, rigidity synthetic material, and shore hardnesses such as acryl resin, plexiglas, printing roller bearing, cellulose, acetate fat, hardwood, nylon, acetal resin are measured.

The utlity model has the advantage that structure is simple, cost is lower, measuring accuracy is higher, easy to operate.
