Abstract
A burglar-proof quick centering base of a GPS receiver is used for connecting a GPS receiver antenna with an observation pier when in observation. The device comprises a screw shaft at the upper end and a connecting base at the lower end, an inner sleeve is connected with the connecting base, the inner sleeve is sheathed inside a middle sleeve, the middle sleeve is connected with the screw shaft, the middle sleeve is sheathed inside an outer sleeve, C-shaped snap rings are installed between the outer sleeve and the middle sleeve as well as between the middle sleeve and the inner sleeve, the outer sleeve, the middle sleeve and the inner sleeve are all provided with openings, and a burglar-proof bolt is matched with the openings. After an instrument is installed at the observation pier by the base, centering leveling and antenna gauge height are not needed, thereby having convenient operation and improving the working efficiency of measurement; the GPS receiver antenna is safely fixed on the observation pier by the coincidence of round orifice center lines of three rotable column sleeves of the base and by means of the burglar-proof bolt, thereby having good outdoor burglar-proof performance; the base has small volume, and is convenient and practical in outdoor work.
Description
Technical field
The present invention relates to a kind of GPS of being used for receiver installed device, particularly a kind of centering fast, and have the pedestal of anti-theft feature.
Background technology
The GPS receiver more generally adopts in side slope or engineering works etc. being carried out the periodically deforming monitoring, the observation personnel carry a series of instrument annexes to field survey at every turn, before observation, to do a lot of preliminary works, comprise: carry out the pedestal installation and be connected with antenna, and carry out horizontal adjustment and centering, also to carry out repeatedly antenna amount height and record, to guarantee the accurate of observed result, in the operating process of reality, be pretty troublesome, need many times of cost.On the other hand, in measuring process, if staff's busy temporarily (such as near, 2～3 measuring points observation personnel will go to put) leaves current measuring point, the instrument annex of observing personnel promptly will carry so is a lot, and field work is very inconvenient; Can worry device losses again.
Summary of the invention
One of the problem to be solved in the present invention is to reduce the pedestal volume, reduces complex steps and the trouble of bringing and the waste of time of centering, leveling; Two of the problem that solves is to make pedestal have anti-theft feature preferably, be fixed on instrument on the observation pier after, if the interim busy measuring point that leaves of staff in the measuring process, other people are difficult to instrument unloaded and take away, thereby strengthen its anti-theft feature.
The object of the present invention is achieved like this: a kind of GPS receiver anti-theft type quick centering base, what comprise the screw shaft of upper end and lower end is connected pedestal, inner sleeve be connected pedestal and connect, inner sleeve is set in the intermediate sleeve, intermediate sleeve is connected with screw shaft, and intermediate sleeve is set in the outer sleeve, between outer sleeve and the intermediate sleeve to be provided with C shape snap ring between interior intermediate sleeve and the inner sleeve, be equipped with perforate on outer sleeve, intermediate sleeve and the inner sleeve, Theftproof bolt matches with perforate.
GPS receiver anti-theft type quick centering base provided by the invention, base bottom surface is designed near seamless with observation pier top levels and is connected, and the central point of pedestal center line and observation pier is on same vertical curve, after the GPS receiver was connected with this pedestal and is placed on the observation pier like this, the geometric center of GPS receiver was coaxial centering with observing the pier central point; Because this base height is designed to 4cm, greatly reduce than traditional base height (being generally about 12cm), make the geometrical offset amount that causes because of the pedestal slight inclination greatly reduce.Saved and traditional instrument has been carried out centering, leveling and the high operation of GPS receiver antenna amount, improved the efficient of surveying work greatly.
This pedestal be designed to from the inside to surface three can coaxial rotation the cylinder type metal sleeve, in each cartridges sides a circular hole is arranged.Principle according to three conllinear, have only when the circle hole centreline conllinear on three sleeves, just can reverse in two axle (i.e. this pedestal and the central shaft of observing pier be connected and pedestal be connected main shaft) with the GPS receiver antenna, so just can make pedestal and observation pier, pedestal is realized separating with the GPS receiver antenna, thereby carries out the loading and unloading of instrument.Circle hole centreline in order to realize needing loading and unloading on three sleeves can conllinear, does not also promptly depart from, and has designed the Theftproof bolt that can insert in the perforate, so just can rotate interior smoothly instrument is loaded and unloaded.If the interim busy needs of survey crew leave a moment, as long as take out down latch, and arbitrarily rotate a lower sleeve and get final product, common people do not know this operation skill, without Theftproof bolt with the circular hole center conllinear on three sleeves, just the GPS receiver can't be taken off from pedestal, also pedestal can't be disassembled from the observation pier.So just played the effect that prevents that instrument and equipment is stolen.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, what the present invention includes the screw shaft 8 of upper end and lower end is connected pedestal 4, inner sleeve 3 be connected pedestal 4 and connect, inner sleeve 3 is set in the intermediate sleeve 2, intermediate sleeve 2 is connected with screw shaft 8, and intermediate sleeve 2 is set in the outer sleeve 1, between outer sleeve 1 and the intermediate sleeve 2 to be provided with C shape snap ring 7 between interior intermediate sleeve 2 and the inner sleeve 3, be equipped with perforate 6 on outer sleeve 1, intermediate sleeve 2 and the inner sleeve 3, Theftproof bolt 5 matches with perforate 6.
Among the present invention, screw shaft 8 is used to connect the GPS receiver, connects pedestal 4 and is connected with the observation pier.C type snap ring 7 makes outer sleeve 1, intermediate sleeve 2 and 3 three layers of coaxial intussusception of column type sleeve of inner sleeve.
When the present invention uses, will be fixedly placed on the observation pier by pedestal 4 earlier, pedestal 4 is exactly horizontal centring automatically like this, need not to regulate.When the GPS receiver antenna with regulate with regard to not needing after this pedestal is connected, be exactly horizontal centring automatically.Then with pedestal outer sleeve 1, intermediate sleeve 2 and 3 three pivotable sleeves of inner sleeve are rotated from outside to inside, make perforate 6 coincidences on three sleeves, Theftproof bolt 5 is inserted in three perforates that overlap, at this moment the GPS receiver antenna is screwed on this pedestal screw shaft 8.After the GPS receiver antenna is connected pedestal, Theftproof bolt is taken out, rotate arbitrarily that three rotational sleeves no longer overlap the perforate 6 on it, this sampling instrument just is fixed on the observation pier, and the staff just can directly measure.If the interim busy needs of survey crew are away from keyboard, needn't worry that also instrument and equipment is disassembled and loses.
