Detailed description of the invention
See figures.1.and.2 and this utility model is described further.
nullA kind of concrete injection resistance meter，Including base 4、Test portion container 5、Pressure gauge (not shown)，And it is fixed on the pressure measurement head 1 on support 3，Pressure measurement head 1 upper end is oil-in 2，Lower end is penetration needle 6，Inside is oil pocket (not shown) and dynamometer link (not shown)，Fixed disk 27 and movable disk 25 it is provided with in oil-in 2，The inner wall sealing of fixed disk 27 and oil-in 2 is arranged，Fixed disk 27 is provided with the through hole 22 that fuel feeding passes through，Movable disk 25 is positioned at the lower section of fixed disk 27，Movable disk 25 is provided with slide bar 26，Slide bar 26 is through fixed disk 27 and is slidably connected with fixed disk 27，Movable disk 25 is provided with the plugging block 24 for blocking through hole 22，The slide bar 26 shaft between fixed disk 27 and movable disk 25 is arranged with extension spring 23，The two ends of extension spring 23 are fixed with fixed disk 27 and movable disk 25 respectively，When original state, described plugging block 24 blocks through hole 22.
When injection resistance meter needs to measure concrete setting time, to oil-in 2 drain the oil, oil flows into fixed disk 27, drain the oil is stopped after a certain amount of, needs are drained the oil, by pressing slide bar 26, slide bar 26 slide downward immediately, meanwhile extension spring 23 two ends stretch, fixed disk 27 is made to separate with movable disk 25, plugging block 24 is away from through hole 22, no longer block through hole 22, oil flows into bottom oil-in 2, subsequently enter oil pocket, when oily q.s in oil pocket, stopping is drained the oil, unclamp slide bar 26, extension spring 23 two ends are shunk, slide bar 26 upward sliding, movable disk 25 is made to reset, now, need to keep still having above fixed disk 27 oil.Pass through arrangement above, the oil flowing into oil pocket does not have air, when penetration needle 6 is produced resistance by test portion, this power is by the fluid in dynamometer link compression seal oil pocket, namely oil liquid pressure increase is indicated by Pressure gauge, the size measuring pressure will not be affected, thus affecting the time measuring concrete coagulation because there being the existence of air.
Oil-in 2 upper port is provided with the lid 21 for sealed port, it is prevented that oil-in 2 falls into dust, causes that the purity of oil declines, and impact is measured.
Through hole 22 bottom is truncated cone-shaped enlarging, and plugging block 24 is circular platform type projection, and the purpose so arranged is that circular platform type projection can fully seal through hole 22.
Inwall place between upper end and the fixed disk 27 of oil-in 2 is provided with the first scale and the second scale (not shown), has visual reference degree.When drain the oil, when pasta arrives the first scale i.e. oil full scale, stopping drain the oil, otherwise oil will overflow oil-in 2, cause wasting phenomenon.When draining the oil, pasta arrive the second scale namely stop draining the oil scale time, stop pressing slide bar 26, slide bar 26 upward sliding, make movable disk 25 reset, stop draining the oil, otherwise ullage air is taken advantage of a situation inflow oil pocket, has a strong impact on measurement effect.It addition, slide bar 26 top is provided with pole cap 28, increase the comfort level of finger pressing when pressing slide bar 26.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
