Description
Technical Field
The invention relates to a measurement auxiliary device, in particular to a stable, reliable and convenient-to-operate foot-operated scale foot rest.
Background
During geodetic surveying and engineering surveying, a measuring staff (a leveling staff, a total station reflection prism centering rod, a satellite positioning and measuring centering rod and the like) needs to be erected on a measuring mark point to keep vertical and face a measuring device such as a level, and the vertical state of the staff (the staff) and the deflection angle facing the level directly influence the measuring accuracy. The base of the traditional measuring foot rest (tripod) is flat and belongs to a tripod head type foot rest, and the traditional measuring foot rest cannot be applied to an upright measuring scale, so that a measurer needs to carry out hand operation, namely, whether bubbles of a level on a scale (rod) are centered or not needs to be observed, the measuring scale is in a vertical state by hand, time and labor are wasted, the accuracy and the stability of the measuring scale in the vertical state are difficult to guarantee, and the measuring accuracy is reduced. Chinese patent No. 201420599759.1 discloses a foot-operated measuring foot stool, which comprises two telescopic legs, and a transverse foot rest rod axially perpendicular to the legs is connected to the lower ends of the legs. The measurer pedals the transverse pedal rod, and the measuring foot rest is relatively fixed with the ground by utilizing the self weight of the measurer, so that the verticality of the measuring scale can be conveniently adjusted. However, the following disadvantages are found in practical applications: (1) the fixed connection of horizontal foot rest pole and landing leg can not adapt to the arrangement needs of different topography, can cause the unsettled unstable condition of horizontal foot rest pole or landing leg, leads to measuring the unable peaceful use of foot rest. (2) When a measurer steps on the transverse pedal rod, the foot pressing phenomenon can occur, and the foot rest can not be kept stable for a long time, so that the normal measurement can not be carried out. (3) Telescopic landing leg need surveyor observe the spirit level bubble on scale (pole) with eyes, and both hands control interior outer tube relative movement respectively simultaneously and carry out length control, and when the spirit level bubble was placed in the middle, the screw thread jackscrew on the outer tube was arranged in the locking, relies on the frictional force between screw thread jackscrew and the inner tube to realize interior outer tube relatively fixed. The operation is time-consuming and labor-consuming, the rapid leveling is difficult, and the relative sliding of the inner sleeve and the outer sleeve caused by the looseness of the jackscrew is easy to occur, so that the phenomenon that the staff (rod) deviates from the vertical state and even falls is caused.

Detailed Description
Example 1:
as shown in fig. 1, 2 and 3: there are two landing legs 1 of telescopic, 1 bottom fixedly connected with stabilizer blade 2 of landing leg, have toper stabilizer blade head 3 below the stabilizer blade 2, and stabilizer blade 2 is the cylindricality body, is equipped with first recess 4 in the side of cylindricality body, and the lower extreme of first recess 4 is fixed with axial vertically transverse rotating shaft 5, and transverse rotating shaft 5 rotates with the one end of connecting rod 6 to be connected, and connecting rod 6 can rotate around pivot 5 promptly, and relative first recess 4 reciprocates. The other end cover of connecting rod 6 has the lantern ring 7, and 7 surface mounting on the lantern ring have a footboard 8, can avoid the surveyor to press against the foot phenomenon appear when stepping on. Be equipped with through-hole 9 on the lantern ring 7, have threaded connection in the through-hole 9 in the spacing screw 10 of connecting rod 6, spacing screw 10's effect rely on and the through-hole 9 between the clearance, make footboard 8 can make the low-angle rotation around connecting rod 6, avoid 8 wide-angle rotations of footboard to appear overturning influence foot to step on simultaneously. A spring 11 (tension spring) is fixed at the upper end of the first groove 4, the other end of the spring 11 is connected with the connecting rod 6 near the transverse rotating shaft 5, and the spring 11 is used for enabling the connecting rod 6 to be folded upwards when the user steps on the connecting rod, so that the supporting legs 2 can be flexibly arranged on the ground conveniently.
Example 1 procedure: referring to fig. 1, as in the prior art, a measuring staff (rod) 20 is provided, a level 21 is fixedly connected to the measuring staff (rod), a foot stool base 22 is connected to the middle lower portion of the measuring staff (rod) 20, and the top end of the leg 1 is rotatably connected to the foot stool base 22. The surveyor firstly erects the measuring staff (rod) 20 on a ground measuring point, then opens the supporting legs 1 to enable the supporting leg heads 3 to be arranged on the ground, then steps on the pedals 8 with feet to enable the supporting leg heads 3 to be fixed with the ground, and then observes the level 21 to adjust the telescopic supporting legs 1 to enable the measuring staff (rod) 20 to be in a vertical stable state. The rotation (up-down movement) of the connecting rod 6 and the small-angle rotation of the pedal 8 ensure the arrangement requirements of the measuring foot rest on different grounds.
Example 2:
fig. 4, 5, 6 and 7 show a basic structure example 1 different from example 1. The supporting leg 1 is composed of a lath 1-1 and a sleeve 1-2 which is sleeved outside the lath 1-1 and can move relative to the lath 1-1, a plurality of holes 1-3 with close intervals are vertically arranged on the lath 1-1, and the interval and the diameter of the holes 1-3 meet the requirement of length adjustment precision. The side surface of the upper end of the sleeve 1-2 is provided with a second groove 1-4, a transversely movable pressing block 1-5 is arranged in the second groove 1-4, and the pressing block 1-5 and the second groove 1-4 can be connected by adopting a slide rail and other connection modes. A transverse tension spring 1-6 is fixed between the bottom of the second groove 1-4 and the pressing block 1-5, a lath through hole 1-7 is arranged on the pressing block 1-5, and a clamping column 1-8 matched with the hole 1-3 is arranged on one side of the lath through hole 1-7, which is positioned on the transverse tension spring 1-6.
Example 2 procedure: the same procedure as that of the embodiment 1 is carried out, except that when the observation level 21 adjusts the telescopic legs 1 to make the measuring staff (rod) 20 in a vertical stable state, a measurer presses the pressing blocks 1-5 by hand to move the pressing blocks into the grooves 1-4, and at the moment, the clamping columns 1-8 are separated from the holes 1-3 of the lath 1, so that the lath 1-1 can be conveniently adjusted to move up and down in the sleeve 1-2. When the bubble of the level 21 is centered, the surveyor releases the pressing block 1-5, and the clamping columns 1-8 are embedded into the holes 1-3 of the batten 1 under the action of the transverse tension springs 1-6 to fix the batten 1-1 and the sleeve 1-2 relatively.
