Description
Technical field
The present invention relates to a kind of holder device, particularly relate to a kind of centering rod support.
Background technology
Mapping centering rod, as aligning equipment indispensable in mapping, has purposes widely in mapping, and it is the metallic rod that can be pointing directly at land mark point by vertical.When general centering rod uses, need support that it is aided with supporting role.
The lowermost end of a spike of existing centering rod support is all sharp, in view of the three-legged structure of support with centering rod composition is to stablize very much, is highly suitable for the place such as construction site, highway.But, if using on smooth floor or on wet and slippery and the most irregular stone, the most restricted, the most easily skid, and floor of grinding away, or stability is inadequate, and very inconvenient.
Summary of the invention
Present invention is primarily targeted at, overcome deficiency of the prior art, it is provided that a kind of centering rod support, be particularly well-suited on smooth floor use, the local use such as also be adapted in construction site, reach dual-purpose purpose.
The technical problem to be solved is to provide simple in construction, easy to use, the centering rod support of highly versatile, not only can overcome skidding, and floor of will not grinding away, it is ensured that while stability, it is convenient for measuring.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of centering rod support, including two support bars, described support bar includes an outer tube and the telescopic inner tube being inserted in outer tube, and described outer tube and inner tube are fixed by drot gfasplng locking member；Described outer tube end is provided with the pointed nose for landing；Described outer tube outer surface is set with a sleeve pipe that can move along outer tube axial direction, and described cannula tip is fixed with outer tube by securing member；Described cannula end is provided with the claw-like portion for landing；The total length in described sleeve pipe and claw-like portion is less than the length of outer tube.
The present invention is further arranged to: described claw-like portion is to the extraradial three-jaw structure extended down away from outer tube axial direction.
The present invention is further set to: described three-jaw is spacedly distributed on cannula end circumference.
The present invention is further set to: the pawl point in described claw-like portion is set to the pothook type near outer pipe surface bending.
The present invention is further set to: described support bar lives centering rod by connecting modular support.
The present invention is further set to: described connection assembly includes that vertical connecting shaft, one end of described vertical connecting shaft are connected with centering rod by stubborn formula locking member one；The other end of described vertical connecting shaft is connected with two support bars respectively by stubborn formula locking member two.
Compared with prior art, the invention has the beneficial effects as follows: be set with a sleeve pipe that can move along outer tube axial direction by tube outer surface outside, and claw-like portion is set at the end of sleeve pipe, when can be implemented in use on smooth floor, sleeve pipe is put down and pins with securing member, use claw-like portion to land, increase lifting surface area and improve its stability；The pawl point in claw-like portion is set to the structure of bending, the abrasion to floor of the preventing claw point；If needing local in construction site etc. to use support, then original pointed nose can be directly used to land；When the pawl point of pothook type is easy to not use sleeve pipe, improve the steadiness of support by hanging gravity thing, strengthen its wind-proof performance；And original outer tube and inner tube total length not, need support to lengthen in the case of, sleeve pipe can be as another extension pipe, it is achieved lengthen purpose.
Foregoing is only the general introduction of technical solution of the present invention, and in order to be better understood upon the technological means of the present invention, the invention will be further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of centering rod support of the present invention.
Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of centering rod support, including two support bars, it is respectively the first support bar 2 and the second support bar 3, described first support bar 2 includes that the first support bar outer tube 21 and the telescopic first support bar inner tube 22 being inserted in the first support bar outer tube 21, described first support bar outer tube 21 and the first support bar inner tube 22 are fixed by drot gfasplng locking member 23；Identical, described second support bar 3 includes that the second support bar outer tube 31 and the telescopic second support bar inner tube 32 being inserted in the second support bar outer tube 31, described second support bar outer tube 31 and the second support bar inner tube 32 are fixed by drot gfasplng locking member 33.Described first support bar 2 and the second support bar 3 support centering rod 1 by connecting assembly 4；Described connection assembly 4 includes that vertical connecting shaft 41, one end of described vertical connecting shaft 41 are connected with centering rod 1 by stubborn formula locking member 1；The other end of described vertical connecting shaft 41 is connected with the first support bar 2 and the second support bar 3 respectively by stubborn formula locking member 2 43.
The end of aforesaid first support bar outer tube 21 and the second support bar outer tube 31 is separately provided for the first pointed nose 24 and the second pointed nose 34 landed.Described first support bar outer tube 21 is set with a first sleeve 25 that can move along the first support bar outer tube 21 axial direction, and described first sleeve 25 top is fixed with the first support bar outer tube 21 by a class securing member 26；Described first sleeve 25 end is provided with the first claw-like portion 27 for landing；The total length in described first sleeve 25 and the first claw-like portion 27 is less than the length of the first support bar outer tube 21；Identical, described second support bar outer tube 31 is set with second sleeve pipe 35 that can move along the second support bar outer tube 31 axial direction, and described second sleeve pipe 35 top is fixed with the second support bar outer tube 31 by two class securing members 36；Described second sleeve pipe 35 end is provided with the second claw-like portion 37 for landing；The total length in described second sleeve pipe 35 and the second claw-like portion 37 is less than the length of the second support bar outer tube 31.
