Described display screen simulating rod and weight fork are equipped with the damping unit to both relative motions.
This cubing is relatively directly used the technology of height gauge to need not operator's health and is shifted back and forth and goes carefully numerical value and the calculated difference of observation memory height gauge for twice, but directly automatically shows qualified noly, and operation is convenient, and speed is fast, operating personnel's indefatigability.And compare laser method and inclination angle digital display instrument rule has extremely low cost, be convenient to a large amount of uses, and very simply more reliable and stable because of structure, the life-span is long, the also extensive operation service condition of industry spot preferably.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
1. display screen simulating rods among the figure, 2. bearing pin, 3. weight fork, 4. electric switch, 5. displaying alarm, 6. power supply, 7. damping unit, 8 display screen bracing frames.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with accompanying drawing and specifically preferred embodiment the utility model is described in further detail.
Referring to accompanying drawing, this preferred embodiment---a kind of weight fork adds the cubing of electric switch automatic discrimination display screen bracing frame drop.Its making and use all very simple: both place display screen simulating rod 1 and weight fork 3 face-to-face the bearing pin 2 of also being installed by a level and swing hinged and mutually free rotation (known configurations gets final product), and its mass distribution is lower heavy light (can consciously the bottom being done heavily a bit take bearing pin 2 as reference point, such as similar weight shape), when display screen simulating rod 1 during around bearing pin 2 axis rotation that level is installed the weight fork keep motionless because of following weight; Be preferably made with display screen simulating rod 1 shape similarly shaft-like by display screen simulating rod 1 part on the weight fork 3, so that both stocks are from forming maximum relative rotation angular displacement between bearing pin 2 distal-most end to react more significantly drop, and (also can in two ends also to be preferably in the distal-most end of this one, for asking simple this example only at one end) respectively be equipped with between the two an electrode (also can utilize the part of bar self-conductive make its local shape do a little variations take into account form electrode) formation electric switch 4,4 of electric switches connect to note whether needing insulation with electrode, all conducting does not form short circuit when power supply 6 and displaying alarm 5(note such as 3 of display screen simulating rod 1 and weight forks as electric conductor with flexible thin wire); This wherein weight fork 3 be relative stationary electrode because of the electrode of weight effect on it, on the display screen simulating rod 1 is the movable electrode of phase opposing connection bearing pin 2; Because this example only at one end fills electric switch 4, therefore an electrode in two electrodes can change into discrete one-tenth occupy another electrode up and down two disjunct sub-electrodes of both sides (sub-electrode links to each other and also can, but can not take into account and specifically tell drop is that the left side is high or the right is high, therefore this case is not adopted), two electric switches 4 of up and down two limit positions of left and right sides drop have been equivalent to form, so that no matter display screen simulating rod 1 around bearing pin 2 clockwise or rotate counterclockwise as long as display screen left or right arbitrary limit tilt (drop is namely arranged) just can both differentiate, can also taking into account simultaneously when forming electric switch 4 and a displaying alarm 5 respectively is installed with stationary electrode respectively such as two sub-electrodes, differentiation is that the left side is high or the right is high.Displaying alarm 5 for the sake of simplicity available pilot lamp and or hummer, power supply 6 can use direct current (such as dry cell, rechargeable battery etc.) or the interchange all can, its position is placed on the relatively good part that can doublely make weight in weight place on the weight fork 3 during with battery; Then be fixed on the table top relatively good during with interchange; Power supply 6 gets final product with displaying alarm 5 usefulness flexible circuit conductor flexible joint electric switches 4 electrodes; Above-mentioned relevant electric aspect all can adopt known technology.It should be that the drop value sets according to the height difference of the good bar both end sides regulation of prior conversion that two interelectrode corresponding distance values relations of angular displacement are arranged relatively, all two electrodes do not contact namely surperficial in qualified permissible value scope, otherwise two electrode contacts conduction, displaying alarm 5 actions are for defective.Electrode when measuring first, cause needs calibrate by known technology elder generation's leveling worktable and to cubing, therefore also can be made into screw-like so that in time adjust its contact position or spacing in case of necessity.
Because of this cubing usage comparison frequent, for the duration of oscillation that shortens weight fork 3 to accelerate detection speed, can be equipped with on the cubing the damping unit 7 of display screen simulating rod 1 with 3 both relative motions of weight fork.This damping unit 7 can adopt known technology, and such as oil damping, air chamber air damping etc., this example adopts the damping of electromagnetic eddy effect.Namely at weight fork 3(or display screen simulating rod 1) utilize it own or add in addition that to load onto fritter conduction good but consist of the eddy-current damping plate for nonmagnetic material (such as copper coin, aluminium sheet etc.) etc., display screen simulating rod 1(or weight fork 3) above damping sheet is loaded onto two magnetic poles and the magnetic field that forms by damping sheet (is preferably the fairly simple of permanent magnetism, without connecting wire burden and involving power), when both have relative motion, can make time spent vertical fork because of mutual electromagnetic damping and stop swinging rapidly.
The display screen simulating rod 1 that weight fork 3 will be housed during use is installed on the computer support 8, and is no according to displaying alarm 5 actions, can judge directly that drop is qualified not no and which side is high or low.
This technology makes the operator need not health and is shifted back and forth and removes carefully observation memory both heights chi altitude information for twice and calculate its difference, can automatically directly differentiate drop according to displaying alarm qualified no, and operation is convenient, and speed is fast.(wherein the digital display incidence meter wants the operator carefully to see and differentiate digital defective in addition and compare laser method and inclination angle digital display instrument, more direct not and convenient) then have an extremely low cost, construct very simple, work is used more reliably, stable, the life-span is long, operation also can be more extensive, industry spot operation service condition preferably.
