Preferably, measuring sonde is a kind of in adamas probe, steel ball probe and sintered carbide ball probe.
Preferably, sclerometer body is provided with hand-held position.
Preferably, measuring tube is set with the baffle plate offseted with mould, baffle plate is connected with Handheld Division by extrusion spring, and the stiffness factor of extrusion spring is less than the stiffness factor of energy-stored spring.
Preferably, extrusion spring to be arranged on outside measuring tube and coaxially to arrange with energy-stored spring.
Preferably, extrusion spring is distributed on outside measuring tube.
Preferably, measuring tube be provided with along measuring tube central axial direction arrange scale for measuring the degree of depth of groove/opening to be measured.
A kind of portable die hardness measuring device provided by the invention, measuring tube stretches in groove/opening and makes to offset bottom measuring sonde and groove/opening, drive measuring sonde by sclerometer body and offset until measuring sonde flushes with bottom groove/opening bottom groove/opening, measuring sonde drives energy-stored spring, carriage release lever moves up, the pointer that teeth groove on carriage release lever drives transmitting gear to rotate in drive hardness indicator gauge swings, thus hardness and the intensity of Measurement die can be read on hardness indicator gauge, by the rack geared adopted, measuring accuracy, measurement efficiency is high.The present invention is set with baffle plate on measuring tube, and baffle plate is connected with sclerometer body by extrusion spring, ensures the bottom in measuring sonde vertical insertion grooves/hole, improves measuring accuracy further and measures efficiency.Measuring tube in the present invention is provided with the scale arranged along measuring tube central axial direction, can be used for measuring the degree of depth of groove/opening, has widened purposes of the present invention.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, Fig. 1 is the surface structure schematic diagram of a kind of portable die hardness measuring device that the present invention proposes; Fig. 2 is the inner structure schematic diagram of a kind of portable die hardness measuring device that the present invention proposes; Fig. 3 is the structural representation of a kind of portable die hardness measuring device specific embodiment that the present invention proposes.
With reference to Fig. 1, Fig. 2, a kind of portable die hardness measuring device that the present invention proposes, comprise sclerometer body 1 and measurement mechanism 2, measurement mechanism 2 comprises measuring tube 20, measuring tube 20 is vertically set on the side of sclerometer body 1 and is connected with sclerometer body 1, sclerometer body 1 is provided with hand-held position, sclerometer body 1 front is provided with hardness indicator gauge 11, energy-stored spring 21 is provided with in measuring tube 20, measuring tube 20 one end stretching into sclerometer body 1 inside is provided with the carriage release lever 22 be connected with energy-stored spring 21, measuring sonde 23 is provided with in measuring tube 20 away from sclerometer body 1 one end, measuring sonde 23 is sintered carbide ball probe, measuring sonde 23 passes measuring tube 20 under energy-stored spring 21 free state, carriage release lever 22, measuring sonde 23 is arranged on the two ends of measuring tube 20 along the central axis of measuring tube 20, carriage release lever 22 arranges in the gathering sill in sclerometer body 1, the side opening of carriage release lever 22 is provided with teeth groove, teeth groove is arranged along the length direction of carriage release lever 22, sclerometer body 1 inside is provided with transmitting gear 12, transmitting gear 12 arranges with the central axis of hardness indicator gauge 11 and drives indicators turn, transmitting gear 12 is suitable with the teeth groove on carriage release lever 22, measuring sonde 23 and groove/opening to be measured offset and drive energy-stored spring 21 upwardly carriage release lever 22, teeth groove on carriage release lever 22 drives transmitting gear 12 rotation to realize pointer and deflects on hardness indicator gauge 12.
Using method of the present invention is as follows: measuring tube 20 stretches in groove/opening and makes to offset bottom measuring sonde 23 and groove/opening, drive measuring sonde 23 by sclerometer body 1 and offset until measuring sonde flushes with bottom groove/opening bottom groove/opening, measuring sonde 23 drives energy-stored spring 21, carriage release lever 22 moves up, the pointer that teeth groove on carriage release lever 22 drives transmitting gear 12 to rotate in drive hardness indicator gauge 11 swings, thus hardness and the intensity of Measurement die can be read on hardness indicator gauge 11, the rack geared of the present invention by adopting, measuring accuracy, measurement efficiency is high.
