By adjusting the relative position between the length or support rod and centering rod of support rod, so that the body of rod and horizontal plane, the body of rod
Vertical degree directly affect mapping precision, and the body of rod easily shakes, tilts when in use, and then influences mapping knot
Fruit.In addition, cannot arbitrarily be dismantled between support rod and the body of rod, if support rod or body of rod damage, can only buy a whole set of centering again
Bar is surveyed and drawn at high cost.
Utility model content
The purpose of this utility model is to provide a kind of mapping centering rods, to solve mentioned above in the background art ask
Topic.
Used technical solution to solve above-mentioned technical problem: a kind of mapping centering rod, including centering bar body and branch
Support, support frame as described above include connection component and three retractable support levers, the connection component include connecting plate, ball base and
Universal caster, three retractable support lever compartment of terrain are hinged on connecting plate, and the ball base is fixed in connecting plate
Portion, the Universal caster are mounted on ball base, and the ball base is equipped with one for holding out against or unclamping the top of Universal caster
Tight bolt, is connected with a connecting screw on the Universal caster, the bottom of the centering bar body be equipped with internal screw thread with even
Screw flight connection is connect, the top of the centering bar body is equipped with supporting block, and the supporting block is equipped with air level.
Further, the retractable support lever includes upper support leg and lower support leg, and the lower support leg is movably set in branch
In foot, it is provided with elastic button on the lower support leg, multiple positioning matched with elastic button are provided in the upper support leg
Hole.
Further, spring is provided in the upper support leg, one end of the spring is fixed on the top of upper support leg, another
End is fixedly connected with lower support leg.
Further, the centering bar body is carbon fibre materials.
The utility model has the advantages that the utility model is simple and reasonable, it is detachable between centering bar body and support frame, therefore when branch
When support or centering bar body are damaged, the part of damage need to be only bought again, is not necessarily to basket purchase, reduce mapping cost；Due to
Centering bar body is connect by Universal caster with support frame, is provided with air level in centering bar body, is passed through Universal caster and water
Anywhere the cooperation of quasi- bubble, centering bar body can all keep horizontal positioned, meanwhile, because retractable support lever is hinged on
On connecting plate, therefore retractable support lever can be unfolded or collapse, and by adjusting retractable support lever, adjustable centering
The height of bar body meets mapping and requires.
Detailed description of the invention
The utility model is described further with reference to the accompanying drawings and examples:
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structural schematic diagram of connection component in the utility model；
Fig. 3 is the structural schematic diagram of retractable support lever in the utility model.
Specific embodiment
Referring to Figures 1 and 2, the utility model is a kind of mapping centering rod, including centering bar body 1 and support frame, support
Frame includes connection component 2 and three retractable support levers 3, and connection component 2 includes connecting plate 21, ball base 22 and Universal caster
23, three 3 compartment of terrain of retractable support lever are hinged on connecting plate 21, and ball base 22 is fixed on the middle part of connecting plate 21, universal
Ball 23 is mounted on ball base 22, and ball base 22 is equipped with one for holding out against or unclamping the puller bolt of Universal caster 23
24, be connected with a connecting screw 25 on Universal caster 23, the bottom of centering bar body 1 be equipped with internal screw thread with connecting screw 25
It is threadedly coupled, the top of centering bar body 1 is equipped with supporting block 4, and supporting block 4 is equipped with air level 5.
This mapping centering rod it is simple and reasonable, it is detachable between centering bar body 1 and support frame, therefore work as support frame
Or when the damage of centering bar body 1, the part of damage need to be only bought again, it is not necessarily to basket purchase, reduces mapping cost；Due to centering
Bar body 1 is connect by Universal caster 23 with support frame, air level 5 is provided in centering bar body 1, therefore pass through Universal caster
23 with the cooperation of air level 5, anywhere centering bar body 1 can be turned to suitable position around Universal caster 23,
Puller bolt 24 is tightened again, so that Universal caster 23 can not rotate, so that mapping centering rod keeps horizontal positioned, meanwhile,
Because retractable support lever 3 is hinged on connecting plate 21, retractable support lever 3 can be unfolded or collapse, and pass through tune
Whole retractable support lever 3, the height of adjustable centering bar body 1 meet mapping and require.
