Description
Technical field
The utility model relates to a kind of measurement mechanism and using method thereof, particularly a kind of with low cost, rainproof antirust, simple, convenient, the coupling arrangement observing prism and forced centering base can be realized rapidly, and substantially can eliminate different time middle observation prism of surveying because installing the vertical error and lateral error that cause, thus simplify deformation observation prism installation, leveling, highly measure, improve accuracy of observation, specifically a kind of observation prism and forced centering base Quick Connect Kit.
Background technology
As everyone knows, appearance deformation observation prism and forced centering base are widely used in engineering survey.Wherein, prism is connected with forced centering base by traditional prism base.And traditional prism base complex structure, expensive, usually use dress with screw be connected with forced centering base, and often measure one-step installation once and leveling again, not only troublesome poeration, length consuming time, also causes the prism setting height(from bottom) between the measurement of different number of times to there is the discrepancy in elevation, and then adds measuring result error.Based on this, research and develop with low cost, simple, convenient, the connection observing prism and forced centering base can be realized rapidly, and substantially can eliminate the coupling arrangement of vertical error that observation prism in different to survey time causes because of installation and lateral error and using method has certain significance.
Summary of the invention
The purpose of this utility model is for existing prism base complex structure, troublesome poeration, expensive, the setting height(from bottom) error of prism and lateral error larger problem when different number of times is measured, there is provided a kind of with low cost, simple, convenient, observation prism and the forced centering base Quick Connect Kit of the connection of prism and forced centering base can be realized rapidly.
The technical solution of the utility model is:
A kind of observation prism and forced centering base Quick Connect Kit, it is characterized in that it comprises spiro column 1 and rain cover 2, the lower end of described spiro column 1 be provided with external diameter be less than spiro column for screwing in the external thread section 5 in prism mounting base 3, being provided with at external thread section 5 and the joint face place of spiro column 1 gasket groove 4 installing waterproof washer additional, spiro column 1 being provided with for external thread section being screwed into the symmetrical force application structure 6 of in forced centering base 3 at least two; The upper end of described spiro column 1 is connected with and the joint pin 8 observing prism 7 grafting be connected, and joint pin 8 is provided with a fixed sturcture 10 inserted for the register pin 9 in prism leveling pedestal 7.
Described fixed sturcture 10 is pin-and-hole or annular pickup groove.
Described force application structure 6 is two symmetrical sections, the quadrilateral of decile or hexagon section.
The beneficial effects of the utility model:
(1) adopt coupling arrangement of the present utility model and using method thereof, the connection observing prism and forced centering base can be realized rapidly.
(2) coupling arrangement of the present utility model and using method thereof, can realize accurate location when prism is installed, and substantially can eliminate different time middle observation prism of surveying because installing coupling arrangement and the using method thereof of vertical error and the lateral error caused.
(3) coupling arrangement of the present utility model and using method thereof, accurately can be located the process implementation that is spirally connected by self structure, further reduces height error and lateral error that in the measurement of different number of times, prism is installed.
(4) coupling arrangement of the present utility model and using method thereof, with low cost, simple, convenient, can be permanently affixed on forced centering base.

A kind of observation prism and forced centering base Quick Connect Kit, it comprises spiro column 1 and rain cover 2(Fig. 3), the lower end of described spiro column 1 be provided with external diameter be less than spiro column for screwing in the external thread section 5 in prism mounting base 3, the gasket groove 4 installing waterproof washer additional is provided with at external thread section 5 and the joint face place of spiro column 1, spiro column 1 is provided with for external thread section being screwed into the symmetrical force application structure 6 of in forced centering base 3 at least two, force application structure 6 can adopt the symmetrical section of two shown in Fig. 2, also the quadrilateral or hexagon section of being convenient to the decile that normal work spanner uses can be adopted.The upper end of described spiro column 1 is connected with and the joint pin 8 observing prism 7 grafting be connected, joint pin 8 is provided with a fixed sturcture 10 inserted for the register pin 9 in prism leveling pedestal 7, described fixed sturcture 10 is and the pin-and-hole of register pin cooperating number or an annular pickup groove, as shown in Figure 1.
As shown in Figure 4, it comprises the following steps using method of the present utility model:
First, sealing packing ring 11 is loaded on (Fig. 4-1) on gasket groove 4;
Secondly, external thread section 5 is connected with the internal thread on forced centering base 3, and blocks section 6 with spanner 12 and tightened fixing (Fig. 4-2);
Again, observation prism 7 is set on joint pin 8, the register pin 9 in observation prism 7 is snapped in pickup groove and can start to measure (Fig. 4-3);
Finally, at the end of measurement, directly take off observation prism, by device indwelling on forced centering base 3, cover rain cover 2 and get final product (Fig. 4-4).
The utility model does not relate to the part prior art that maybe can adopt same as the prior art and is realized.
