Description
Technical field
The present invention relates to measuring device, especially a kind of improved RTK bar.
Background technique
RTK(Real-time kinematic, in real time dynamically) carrier phase difference technology, it is two surveys of real-time processing
The carrier phase that base station acquires is issued receiver user, carries out seeking poor solution by the differential device of amount station carrier phase observed quantity
Calculate coordinate；This is a kind of new common GPS measuring device, pervious static state, rapid static, dynamic measure require afterwards into
Row resolves the precision that could obtain Centimeter Level, and RTK is can to obtain in real time the measuring device of centimeter-level positioning precision in field,
It uses carrier phase dynamic real-time difference method, is the great milestone of GPS application, its appearance be engineering setting out,
Shape mapping, various control measurements bring Neoma Foam, greatly improve operating efficiency.
RTK bar used at present is because it is a metal tube entirety, during measurement is got ready, due to by head and this
Body weight effect, so that fierce collision occurs for RTK bar low side and ground, since RTK bar and head are rigid connection, stress will lead to
It crosses RTK bar and is transmitted to head bottom, prolonged and repeated collision will damage head inner body, cause instrument failure, damages.
Summary of the invention
The present invention is intended to provide a kind of improved RTK bar, to reduce RTK bar in measurement process, external force is to head instrument
Impact.
The technical solution adopted by the present invention: a kind of improved RTK bar, including top connecting rod and lower coupling pole, upper
Connector sleeve is set between portion's connecting rod and lower coupling pole, and the upper end of connector sleeve is connect with top connecting rod lower thread, even
It is provided with compressed spring in female connector, the lower end surface of connector sleeve is provided with through-hole, the upper end of lower coupling pole is put in by through-hole
In female connector, lower coupling pole and through-hole are clearance fit, in the horizontally disposed round cushion block in the upper surface of lower coupling pole, circular pad
The outer diameter of block is greater than through-hole internal diameter, and compressed spring lower end surface and round cushion block are in close contact, and compressed spring upper surface and top connect
Extension bar lower end surface is in close contact.
As a further improvement, the lower end of lower coupling pole is inverted-cone shape structure, the small end of pyramidal structure is spherical surface.
As a further improvement, the small end face of pyramidal structure is provided with wearing layer.
By adopting the above technical scheme, RTK bar is in measurement process, and when being contacted with ground, compressed spring passes through for RTK bar lower end
Stress is absorbed to extend stress time, is reduced same momentum and is changed the stress that lower object is subject to, to reach cushioning effect.
Certain compressed spring must have certain rigidity, in measurement process, will not be compressed, influence measurement accuracy；Compressed spring
It is set in connector sleeve, and connects RTK bar top and RTK bar lower part, make an entirety, and be capable of fixing spring,
It is allowed in upright state.The inventive structure is simple, and damping effect is obvious, can effective protection instrument.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is connecting jacket structure schematic diagram；
Fig. 3 is another structural schematic diagram of the utility model；
In attached drawing: 1 top connecting rod, 2 lower coupling pole, 3 connector sleeve, 4 compressed spring 5,6 through-hole of round cushion block.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of improved RTK bar, including top connecting rod 1 and lower coupling pole 2, top connect
The upper end of extension bar 1 is for installing measuring head, that is, measuring instrument, and on top, the lower end of connecting rod 1 is provided with outer spiral shell
Line.
Connector sleeve 3 is set between top connecting rod 1 and lower coupling pole 2, the upper end of connector sleeve 3 is provided with internal screw thread,
The upper end of connector sleeve 3 is connect with 1 lower thread of top connecting rod.
Compressed spring 4 is provided in connector sleeve, certain compressed spring 4 must have design rigidity, if rigidity is too small,
It will affect measurement accuracy, if rigidity is too big, just do not have the protective effect to head.
The lower end surface of connector sleeve 3 is provided with through-hole 6, the upper end of lower coupling pole 2 is put in connector sleeve 3 by through-hole 6,
Lower coupling pole 2 and through-hole 6 are clearance fit, that is, lower coupling pole 2 can be freely axially moved；
When actual installation, needs that lower coupling pole 2 is first passed through through-hole 6, then compressed spring 4 is installed, reconnect top connecting rod
1。
In the horizontally disposed round cushion block in the upper surface of lower coupling pole, the outer diameter of round cushion block is greater than the internal diameter of through-hole 6, this
Sample guarantees that lower coupling pole 1 will not fall off out of connector sleeve 3.
4 lower end surface of compressed spring and round cushion block 5 are in close contact, 4 upper surface of compressed spring and 1 lower end surface of top connecting rod
It is in close contact, it is sufficiently rigid to ensure that whole RTK bar has in this way.
As a further improvement, the lower end of lower coupling pole 2 is inverted-cone shape structure, the small end of pyramidal structure is spherical surface.
As a further improvement, the small end face of pyramidal structure is provided with wearing layer, layer of charcoal or spray coating are such as seeped, in this way may be used
Significantly to extend RTK bar service life.
