Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.The most identical parts are presented with like reference characters.It should be noted that, the word "front", "rear" that uses in describing below, "left", "right", the noun of locality such as "up" and "down" refer only to the direction in accompanying drawing, and word " interior " and " outward " refer respectively to the direction towards or away from particular elements geometric center.
A kind of geotextiles calibrator, by base 9 as main body, base 9 connects a support bar 3 with supporting role, one gimbal lever 7 is set in the upper end of support bar 3, the gimbal lever 7 is hinged with support bar 3, the gimbal lever 7 is left, the right side is respectively arranged at two ends with counterweight 1 and counterweight 8, a datum plate 11 being used for placing geotextiles is placed on base 9, datum plate 11 is provided with the presser feet 10 that measured object applies power, presser feet 10 is provided with the depression bar 6 for transmitting pressure to presser feet 10, this depression bar 6 is positioned at below the gimbal lever 7, depression bar 6 upper end is provided with read head 5, being provided with on support bar 3 can be the adjusting means that the gimbal lever 7 moves up and down around self convert rotational motion by support bar 3, structure as shown in Figure 2.
So, using before geotextiles calibrator, operator can first rotary supporting rod 3, by the adjusting means arranged, by the up and down motion that convert rotational motion is the gimbal lever 7 of support bar 3, thus the deformation quantity of standard of compensation plate 11, it is ensured that geotextiles calibrator certainty of measurement.Simultaneously as compensate for the deformation quantity of datum plate 11, allow the pointer of read head 5 make zero, allow operator measure when direct reading, decrease the number of times of record and eliminate the process of calculating, reduce occur measuring error probability.
This device can be accomplished by: support bar 3 lower end edge support bar 3 direction is provided with a worm screw 13, and worm screw 13 is fixing with support bar 3 to be connected；Base 9 is provided with and the worm gear 12 of worm screw 13 engaged transmission, and wherein the way of restraint of worm gear 12 is to be realized by the rotary shaft of fixing worm gear 12.The upper end of support bar 3 is provided with a slide block 4, the screwed hole along support bar 3 direction and pilot hole 17 is offered on slide block 4, thread segment is offered on support bar 3, thread segment closes with the corresponding threaded holes with slide block 4, base 9 is provided with guide post 2 that is parallel with support bar 3 and that coordinate with pilot hole 17, structure as shown in Figure 2.
Pass through which, when rotating worm gear 12, worm gear 12 drives worm screw 13 to rotate, support bar 3 rotates together also with worm screw 13, owing to slide block 4 and support bar 3 use threaded, and under the effect of guide post 2 constraint, slide block 4 moves up and down only along guide post 2 direction, and the gimbal lever 7 is hinged on slide block 4, thus slide block 4 is also achieved that moving up and down of the gimbal lever 7 along moving up and down of guide post 2, say, that support bar 3 is converted into moving up and down of the gimbal lever 7 around the rotation of self.
In order to the rotation making worm gear 12 in the measurements is more convenient, a handle 16, structure as shown in Figure 2 can be set on worm gear 12.
By this handle 16, operator can apply rotating torque to worm gear 12 easily, so that worm gear 12 rotates, has reached to make the rotation more easily effect of worm gear 12.
Slide block 4 is by moving up and down along guide post 2 direction, so the stable motion of slide block 4 is also had a significant impact by the frictional force reduced between slide block 4 and guide post 2.Therefore being fixed with self-lubricating bearing 14 in the pilot hole 17 of slide block 4, this self-lubricating bearing 14 coordinates with guide post 2, structure as shown in Figure 2.
By arranging self-lubricating bearing 14, it is possible to reduce the frictional force between guide post 2 and pilot hole 17, so that the frictional force between slide block 4 and guide post 2 is greatly reduced, due to slide block 4 move up and down mechanical resistance power reduce, reached the effect of slide block 4 easy motion.
Owing to moving up and down of slide block 4 is by driving support bar to realize around worm screw 13 rotation self rotated, and the resistance that worm screw 13 rotates is mainly the frictional force between itself and base 9.To this end, worm screw 13 near one cylinder roller bearing a151 of one end fits of base 9, then cylinder roller bearing a151 is fixed on base 9, structure as shown in Figure 2.
Setting by cylinder roller bearing a151 so that worm screw 13 is connected with base 9 simply by cylinder roller bearing a151, reduces the frictional force suffered by worm screw 13, has reached to be easy to make worm gear 12 drive the effect that worm screw 13 rotates, structure as shown in Figure 2.
For governor motion mentioned above, also having another method to set up, i.e. offer an inverted T shape hole 18 and the turnbarrel 19 matched with inverted T shape hole 18 on base 9, turnbarrel 19 is parallel with support bar 3, and it is threaded connection, structure as shown in Figure 3.
For arranging this mechanism, turnbarrel 19 can be around self rotary motion in inverted T shape hole 18, owing to support bar 3 itself is fixing, when operator moves turnbarrel 19 with hand-screw, the support bar 3 being threaded connection with it can drive the gimbal lever 7 down or up by the way of being threaded in or out, adjustment bar 7 height, reaching operator just can be with the effect of adjustment bar 7 height by rotating the turnbarrel 19 of this mechanism by hand.
For above-mentioned turnbarrel 19, when its rotary motion, the resistance always brought by the friction in inverted T shape hole 18.To this end, coordinate cylinder roller bearing b 152, this cylinder roller bearing b152 to use fixing connection, structure as shown in Figure 3 with inverted T shape hole 18 on turnbarrel.
By arranging cylinder roller bearing b 152, it is to avoid turnbarrel 19 directly contacts with inverted T shape hole 18, greatly reduces the frictional resistance being subject to when turnbarrel 19 rotates, reaches the effect making operator operate turnbarrel 19 the most easily.
It is last it is noted that above example is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
