The position of dynamic stabilizer blade is fixed, the upper end of the fixed foot tube and the lower end Joint of circular connecting frame.Although the structure can be to swashing
The levelness and height of light total powerstation carry out accurate adjusting, but regulative mode is complex, reduces the efficiency of measurement.
Invention content
In view of this, in view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of mapping portable support stand,
By the arc-shaped guide rail of centering type, the precise fine-adjustment to entire support device height is realized, one is kept with the height for measuring target
It causes, and support base weight is small, it is easy to carry.
In order to achieve the above objectives, the present invention uses following technical scheme：
A kind of mapping portable support stand, including support base, tripod and objective table, the support base include interior branch
Seat, outer support and arc-shaped guide rail, the interior bearing and outer support are the loop configuration being arranged concentrically, the interior bearing and outer support
It is fixedly connected by multiple connecting rods, one end of the arc-shaped guide rail is connected with interior bearing, the other end of the arc-shaped guide rail
It is connected with outer support, the tie point A and the tie point B of arc-shaped guide rail and outer support of the arc-shaped guide rail and interior bearing are located at not
In same radial line, the arc-shaped guide rail is three and is circumferentially evenly arranged that arc chute is arranged in the arc-shaped guide rail upper surface,
The tripod includes three telescopic rods, and the lower end of the telescopic rod is hinged slide bar, and the slide bar is slidably matched with arc chute,
Multiple blind holes are arranged in the slot bottom of the arc chute, and the lower end of the slide bar and blind hole are mating.
Further, the groove depth of the arc chute is sequentially reduced on tie point B to the direction of tie point A, described more
The depth of a blind hole is identical.
Further, the lower end of the slider is arranged sliding block, and the sliding block is slidably matched with the arc chute, the sliding block
Through-hole and chamber be set, the circumferentially arranged limit protrusion in slide bar lower part, after through-hole is stretched into the lower end of the slide bar, the limit
Position protrusion is slided in chamber.
Further, resetting spring is arranged in the lower face of the limit protrusion, and the first magnet is arranged in the lower end of the slide bar,
With the second attracted magnet of the first magnet, the suction-combining force between the first magnet and the second magnet is big for the bottom end setting of the blind hole
In the elastic force of resetting spring.
Further, the both ends of the arc-shaped guide rail are respectively articulated with first slide and second slide, the first slide with
Outer support is slidably connected, and the second slide is connect with interior bearing sliding.
The beneficial effects of the invention are as follows：
1. the present invention is hinged slide bar in the lower end of tripod, arc chute, the slot bottom of arc chute are set on arc-shaped guide rail
Multiple blind holes are set, slide bar can not only be slidably matched with arc chute, but also can be mating with blind hole, and the two of telescopic rod
End is hinged with support plate and slide bar respectively, and slide bar is that slidingtype is connect with arc-shaped guide rail, which can realize that telescopic rod is long
Short freely adjusts；This support device when in use, adjusts the length of tripod telescopic rod, makes the height base of whole device first
This arrival predetermined value, and inevitably there are errors for the adjusting of the height of this process, are slided in arc chute by slide bar at this time, and
The tie point A of arc-shaped guide rail and interior bearing is located at from the tie point B of arc-shaped guide rail and outer support in different radial line, makes slide bar
During being slided from sliding slot head end towards tail end, three telescopic rods of tripod do centripetal movement, and the height of whole device is not
The fine tuning of height is realized in disconnected increase, and the mode for reducing whole device height is similar, this is not repeated；It finely tunes to optimal use height
After degree, slide bar is inserted into blind hole and is fixed, and prevents its free to slide；
From the foregoing, it will be observed that the purpose of the present invention is how to realize the accurate tune of the height for the measuring instrument for being placed on support plate
Section realizes the precise fine-adjustment to entire support device height by the arc-shaped guide rail of centering type, and measures target (such as whole station
Instrument and prism) height be consistent, actual use it is significant；Light-weight design especially is carried out to the structure of support base,
The pedestal of opposite plate, influence of the application to whole device weight is smaller, easy to carry and remove and move.
2. to improve the fine tuning amplitude of whole device height, arc chute is carried out special designing, arc chute by the present invention
Groove depth be sequentially reduced on tie point B to the direction of tie point A, slide bar is in arc chute from from tie point B to tie point A
In sliding process, since groove depth is constantly reducing, the position of slide bar is also constantly rising, to be effectively increased whole device height
The amplification of degree expands the range of whole device high fine-tuning；It is improved realization alternatively, it is also possible to the structure to arc-shaped guide rail
The effect successively increases the thickness of arc-shaped guide rail on tie point B to the direction of tie point A, the thickness of arc chute exists
Do not change or successively increase on tie point B to the direction of tie point A, can also realize this technology effect, but virtually increase
The weight of arc-shaped guide rail, the optimal selection scheme of the structure design of the application actual design, the experiment during.
3. the present invention is arranged sliding block in the lower end of the slider, sliding block is slidably matched with arc chute, and through-hole and chamber is arranged in sliding block,
The circumferentially arranged limit protrusion in slide bar lower part, after through-hole is stretched into the lower end of slide bar, limit protrusion is slided in chamber, this structure design
Sliding block is added in the lower end of the slider, sliding block can not only realize that slide bar is indirectly slidably matched with sliding slot, reduces friction between the two
Loss, and the limit protrusion of slide bar is slided in the chamber of sliding block, the structure of slide bar and blind hole can be designed to column or
The rectangular equal regular textures of person, that is, reduce the manufacture difficulty of slide bar and improve the process conditions such as brill, the boring of blind hole.One structure
Variation realize multiple effect.
4. resetting spring is arranged in the lower face of limit protrusion, this structure design can be in order to slide bar fast ski-running out of blind hole
Go out, save manpower, the activity duration, for prevent resetting spring by slide bar the automatic spring out of blind hole, define its elastic force be less than support
The 1/3 of device gravity.
6. for the stability for improving during use of the present invention, the first magnet is arranged in the lower end of slide bar, and the bottom end of blind hole is set
Second magnet attracted with the first magnet is set, when slide bar, which is inserted into blind hole, to be fixed, ensures the grafting effect of slide bar, especially
It is added in the structure of resetting spring in slide bar lower part, the problem of effective pre- antiskid bar freely pops up.
7. the both ends of arc-shaped guide rail are respectively articulated with first slide and second slide, first slide is slidably connected with outer support,
Second slide is connect with interior bearing sliding, and the angle adjustment of arc-shaped guide rail may be implemented in this structure design, you can to change three
The spacing of telescopic rod and interior bearing center, makes the height adjustment range of whole device further increase.
