Abstract
The utility model discloses a measurement instrument which comprises a ruler body 1, a telescopic rod 4, a positioning pin 5, a hinge pin 6, a ruler body 2, a spring 3 and a clamp pin 7. A telescopic rod sliding slot 9 and a hinge pin sliding slot 10 are arranged on the ruler body 2. The ruler body 1 and the ruler body 2 are connected through the telescopic rod 4 and the positioning pin 5. The telescopic rod is telescopic along the ruler body 1. The spring 3 is arranged on the telescopic rod 4, is clamped by the clamp pin 7 and is connected with the ruler body 1. The positioning pin 5 is arranged on the left side of the end face of the ruler body 1. Three horizontal and vertical positioning pin holes are arranged on the ruler body 2. The positioning pin 5 on the ruler body 1 is respectively matched with the positioning pin holes on the ruler body 2. According to the utility model, the measurement instrument has the advantages of simple and reasonable structure and convenient use, and can flexibly switch between a straight ruler, an angle ruler and a T type ruler.
Description
[technical field]
The utility model relates to fields of measurement, relates in particular to a kind of survey instrument.
[background technology]
Many maintenance on-the-spot (non-finishing) of metallurgy industry need be to levelness, verticality, some form and position tolerances such as squareness are effectively measured, use is such as ruler, some simple measurers such as angle square and T-shape chi, but the present ruler that uses, angle square and T-shape chi structure are all fairly simple, can not change mutually, function singleness, node in order to ensure perfectly safe and repair time of repair quality, must be with all measurers of foot when a lot of occasions are used, the not beneficial effect of bringing should be exactly carry the maintenance measurer various, component is heavier, and measurer precision damage frequency is frequent thereupon.
[summary of the invention]
At the shortcoming of prior art, the purpose of this utility model is to provide the survey instrument of the exchange of a kind of simple and reasonable, easy to use ruler, angle square and T-shape chi.
The technical solution adopted in the utility model is: a kind of survey instrument is characterized in that: comprise chi body 1, expansion link 4, register pin 5, bearing pin 6, chi body 2, spring 3, bayonet lock 7, expansion link chute 9 and bearing pin chute 10 are arranged on the chi body 2; Be connected with register pin 5 by expansion link 4 between chi body 1 and the chi body 2, expansion link can be flexible along chi body 1, spring 3 arranged on the expansion link 4, and by bayonet lock 7 screens, link to each other with chi body 1; The end face of chi body 1 keeps left and a register pin 5 is housed on the side, has on the chi body 2 laterally and vertical three dowel holes, and the register pin 5 on the chi body 1 cooperates respectively with dowel hole on the chi body 2.
When survey instrument was ruler, 5 one-tenth clearance fit of the register pin on the chi body 1 were inserted in the dowel hole 81 of chi body 2,9 one-tenth clearance fit of expansion link and chi body 2 expansion link chutes.
When survey instrument is angle square, register pin 5 is extracted from dowel hole 81, and rotated one of them chi body, make 2 one-tenth 90 of chi body 1 and chi bodies
0The right angle state, and make register pin 5 clearance fit insert dowel hole 82.
When survey instrument is the T-shape chi, register pin 5 is extracted from dowel hole 82, and one of them chi body of translation, make register pin 5 insert in the dowel hole 83 2 one-tenth center line plumbnesss of chi body 1 and chi body.
The beneficial effects of the utility model are: simple and reasonable, easy to use, can be in the flexible exchange of ruler, angle square and T-shape chi.
