Fig. 1 is the structural representation of a kind of measure apparatus of youngs modulus in this utility model embodiment；
Fig. 2 is the rearview of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, this utility model is further elaborated.Should be appreciated that
Specific embodiment described herein, only in order to explain this utility model, does not limit this utility model.
As shown in Figure 1, 2, this utility model embodiment relates to a kind of measure apparatus of youngs modulus, including:
Base 10,
Fixing pillar 20, is arranged on base 10；
Middle cross beam 30, is arranged in the middle part of fixing pillar 20 by set lever 70；
Entablature 40, is arranged on fixing pillar 20 upper end；
Steel wire 60, one end is fixed on entablature 40 by locking device 50, and the other end passes middle cross beam
Naturally hang down after the threaded hole of steel of 30；
Positioning sleeve 110, is arranged on base 10 by the hole, location being arranged on base 10；Wherein, fixed
Position set 110 is the sleeve pipe of hollow；The steel wire 60 projection on base 10 overlaps with the center of circle in hole, location.
Locating slide rod 100, one end is provided with centre bore, by locking mechanism 120 by steel wire 60 freely
End is fixed in centre bore；The other end is inserted among positioning sleeve 110；Locating slide rod 100 medium position sets
Being equipped with counterweight mounting groove 80, counterweight mounting groove 80 is " mountain " font, is provided with open slot, is used for installing
With taking-up counterweight.Locating slide rod 100 inserts surface roughness Ra≤1 μm of positioning sleeve 110 one end, location
Overlap surface roughness Ra≤1 μm of 110 inwalls.
Locating slide rod can be moved vertically by the weight of counterweight in positioning sleeve up and down.Can be straight when assembling counterweight
Tipping is arrived inside counterweight mounting groove.Therefore, this structure has and prevents steel wire from waving the advantage rocked, the most again
Preventing counterweight from dropping and injure the danger of experimenter by a crashing object, compensate for unsafe shortcoming, operating process is very convenient
Fast, safe and reliable.
During use, first positioning sleeve 110 being arranged on the centre bore of base 10, positioning sleeve 110 is provided with
Endoporus, this hole inner wall smooth, with locating slide rod 100 with the use of.Then fixing pillar 20 is arranged on
