Make buffer layer absorb the impact force from steel ball through the above technical solutions, steel ball hits buffer layer first, subtracts
Lack steel ball to the impact force of lower plate, to extend the use time of lower plate.
Further, the buffer layer is towards being formed with frosted layer on the face of the steel ball.
Through the above technical solutions, increasing the frictional force between steel ball and buffer layer, so that steel ball, which is stablized, is in holding groove
In, so that steel ball be avoided to bounce the damage for causing glass beaker to the bottom wall of glass beaker from holding groove.
Further, the elastic spacing set is made of heat-resisting material.
Through the above technical solutions, make elastic spacing set can test environment in be stabilized, avoid bearing bed and
Limit sleeve destruction leads to not be tested.
Compared with prior art, the beneficial effects of the utility model are as follows:
(1) by being arranged dismountable elastic spacing set on the locating part of post end, when needing replacing lower plate, only
Elastic spacing set need to be removed from locating part, so that locating part is extracted out from perforating, so that column and lower plate are separated, side
Just dismantle or install lower plate；
(2) by opening up holding groove on lower plate, so that steel ball is fallen in holding groove from bitumen samples, so that steel
Ball stabilization is in lower plate, is avoided steel ball from falling to glass beaker bottom wall and is smashed glass beaker.
