Abstract

The utility model discloses a leveling sighting rod foot rest, have base (1) and with base (1) articulated stabilizer blade (3), base (1) is closed ring -type, cover measure -alike ruler pad (4) that useful elastic material made on base (1) interior side surface horizontal direction in succession. Simple structure, with low costs directly utilizes ruler pad's elasticity to come adjustment and fixed leveling sighting rod, need not to adjust repeatedly stabilizer blade and jackscrew, convenient operation, erects fast, can guarantee measurement probe pole and base and move in -process relatively fixed, portable removes the station, has improved measurement of efficiency greatly.

Description

Measurement of the level mark post foot rest

Technical field

This utility model relates to a kind of auxiliary device of measuring, especially a kind of simple in construction, low cost, easy to operate, set up quick measurement of the level mark post foot rest.

Background technology

In geodesic survey and engineering survey field, need stood upright on ground survey index point and keep steady statue just can measure by measurement of the level mark post (measurement of the level scale, total powerstation reflecting prism centering rod or satellite positioning surveys centering rod etc.).The measurement foot rest that tradition uses, for measuring spider, is made up of tabular pedestal and hinged with pedestal three legs, can be used for the measuring instrument such as level gauge, total powerstation, and cannot be applied to measurement of the level mark post.In order to solve the problems referred to above, the Chinese invention patent of Patent No. 201210267959.2, disclose one " sleeve clip type measurement tripod ", its main contributions is to be changed to ring-type by tabular by the pedestal of tradition foot rest, and on ring-type pedestal, it is evenly equipped with the horizontal jackscrew of at least three, provide special measurement foot rest for surveyors' staff etc. first, improve the degree of accuracy that overcasting staff is the most vertical.The Chinese invention patent of Patent No. 201310022381.9 discloses one " Holding-clamp type measurement foot rest ", the improvement further " sleeve clip type measurement tripod " carried out, its structure has pedestal and the leg connected with pedestal, pedestal is ring-type, having opening on described pedestal, be furnished with two horizontal jackscrews on pedestal, all there is fixed connection apparatus the front end of each horizontal jackscrew, or being furnished with three horizontal jackscrews on pedestal, there is fixed connection apparatus horizontal jackscrew front end placed in the middle；It is mutually perpendicular between described adjacent transverse jackscrew axis.But, " sleeve clip type measurement tripod " and " Holding-clamp type measurement foot rest " the most all there is problems in that

1. the perpendicularity of overcasting staff accurately can be adjusted although with jackscrew, but premise is pedestal should be at level, otherwise jackscrew tilts overcasting staff can produce friction torsion, cause overcasting staff straightening even cannot can damage overcasting staff, it is thus desirable to regulation leg makes pedestal be in level repeatedly, the most also need repeatedly to regulate jackscrew guarantee mark post vertical, troublesome poeration；

2. jackscrew structure does not ensures that being relatively fixed of overcasting staff and pedestal, during removing station, need to separately carry, bring difficulty to surveyor, waste time and energy, and measures efficiency low；

3. structure is complicated, cost is high.

Summary of the invention

This utility model is to solve the above-mentioned technical problem existing for prior art, it is provided that a kind of simple in construction, low cost, easy to operate, set up quick measurement of the level mark post foot rest.

Technical solution of the present utility model is: a kind of measurement of the level mark post foot rest, has pedestal and the leg hinged with pedestal, and pedestal is the ring-type of Guan Bi, and described pedestal inner surface horizontal direction is covered with the equivalently-sized foot pin made with elastomeric material continuously.

Described pedestal is the circle docked by connector by two semicircles.

Described leg is 1 ~ 2, is terminated with the horizontal foot-driven lever axially vertical with leg under described leg.

This utility model simple in construction, low cost, the elasticity directly utilizing foot pin adjusts and fixes measurement of the level mark post, it is not necessary to repeatedly adjust leg and jackscrew, easy to operate, set up quickly；Can ensure that overcasting staff is relatively fixed with pedestal during moving, it is simple to carry and remove station, substantially increase measurement efficiency.

Detailed description of the invention

Embodiment 1:

As shown in Figure 1: have pedestal 1 that the materials such as metal make and with pedestal 1 by the hinged leg 3 of connector 2, leg 3 can be the triangle leg of prior art, can also be 1 ~ 2, the horizontal foot-driven lever 6 axially vertical with leg 3 it is terminated with for 3 times at described leg, pedestal 1 is the rectangle of Guan Bi, and pedestal 1 inner surface horizontal direction is covered with the foot pin 4 of equivalently-sized (height and the consistency of thickness) made with elastomeric material (sponge, rubber, spring pad etc.) continuously.

During use as shown in Figure 2, surveyors' staff 20 is inserted in pedestal 1, to be placed in bottom surveyors' staff 20 on surveying marker point, make surveyors' staff 20 substantially vertical, then make to open and be contacted with ground outside leg 3 to fix, again by observing the bubble position of the spirit level on surveyors' staff 20, adjust the surveyors' staff 20 position in foot pin 4, surveyors' staff 20 can be made to be in plumbness.

Embodiment 2:

As shown in Figure 3,4: substantially the same manner as Example 1, be a difference in that pedestal 1 be described pedestal 1 be by two semicircles circle by connector 5 docking, can more easily circular surveyors' staff 20 be placed in pedestal 1.

Claims

1. a measurement of the level mark post foot rest, there are pedestal (1) and the leg (3) hinged with pedestal (1), pedestal (1) is ring-type for Guan Bi, it is characterised in that: it is covered with the equivalently-sized foot pin (4) made with elastomeric material in described pedestal (1) inner surface horizontal direction continuously.

Measurement of the level mark post foot rest the most according to claim 1, it is characterised in that: described pedestal (1) is the circle docked by connector (5) by two semicircles.

Measurement of the level mark post foot rest the most according to claim 1, it is characterised in that: described leg (3) is 1 ~ 2, is terminated with the horizontal foot-driven lever (6) axially vertical with leg (3) under described leg (3).
