Background

At present, tools for measuring length are used, and tools for directly measuring the coordinates of a certain point are not used. The measurement of the normal size needs to be carried out twice for the sizes on the X axis and the Y axis, and the measurement needs to take a certain process, so that the operation is inconvenient; meanwhile, when the existing longitude and latitude ruler is used for geographic coordinate mapping, the length values measured on each map by the unit longitude and the unit latitude are different due to the fact that the scale of each map is different. When the second value of the geographical coordinate of a certain point is measured on a map, the length values of longitude 1 minute and latitude 1 minute are usually measured on the current map by using a ruler, the length values are used as reference values, then the length value measured in the longitude second value area and the length value measured in the latitude second value area of the measuring point are respectively divided by the reference values to obtain the longitude second value and the latitude second value of the coordinate of the measuring point, and the longitude second value and the latitude second value are measured and calculated again each time when the map is changed, so that the working efficiency is low.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model provides a can get the longitude and latitude chi of map position in a flexible way, the coordinate of surveying out a certain point on the map that can be accurate quick.

In order to solve the technical problem, the utility model discloses a can get longitude and latitude chi of map position location in a flexible way, including long chi, short chi and sliding block, the both sides of long chi respectively are equipped with inwards sunken guide way, the middle part of long chi is equipped with one and goes up narrow "⊥" type spout wide down, and each the guide way with "⊥" type spout sets up in parallel to each other, the both sides portion lock respectively in each in the guide way, the middle part of sliding block be equipped with the arch that "⊥" type spout matches, the sliding block passes through protruding card is gone into realize in "⊥" type spout slide on the long chi, the one end of sliding block extends one side setting of long chi, the one end of short chi cup joints the tip of sliding block, and support perpendicularly in on the side of long chi, the both sides of long chi are equipped with first scale and second scale respectively, be equipped with third scale, fourth scale and fifth scale on the short chi the downside and the middle part of third scale, fourth scale and fifth scale in proper order.

Preferably, the sliding block adopts the transparent plastic material to make, just the arch with sliding block integrated into one piece.

Preferably, the zero graduation lines of the first graduation and the second graduation are positioned on the same X axis.

Preferably, zero scale marks of the third scale, the fourth scale and the fifth scale are positioned on the same Y axis and positioned on the short side where the short ruler and the long ruler are attached to each other.

From the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages:

the utility model provides a can get longitude and latitude chi of map position in a flexible way, realize that the short ruler moves in the longitudinal direction of long chi through the sliding block to realize the quick measurement to map point coordinate, and need not fixed point mark or go on step by step, just can accurate quick survey out the longitude second value and the latitude second value of a certain point coordinate on the map, consequently, improved measurement of efficiency greatly; the utility model has the advantages of simple structure, low production cost, convenient use and convenient carrying.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following drawings and embodiments are connected to further illustrate the present invention in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Examples

Referring to fig. 1-3, the utility model discloses a can measure longitude and latitude chi of map position location in a flexible way, including long chi 1, short chi 2 and sliding block 3, the both sides of long chi 1 respectively are equipped with one inwards sunken guide way 4, the middle part of long chi 1 is equipped with one and goes up narrow wide "⊥" type spout 5 down, and each the guide way 4 with "⊥" type spout 5 sets up in parallel to each other, the both sides portion of sliding block 3 respectively the lock in each in guide way 4, the middle part of sliding block 3 be equipped with "⊥" type spout 5 matches protruding 6, sliding block 3 passes through protruding 6 card is gone into realize in "⊥" type spout 5 slide on the long chi 1, the one end of sliding block 3 extends one side setting of long chi 1, the one end of short chi 2 cup joint the tip of sliding block 3, and perpendicular support in the both sides of long chi 1, the both sides of long chi 1 are equipped with first scale 101 and second scale 102 respectively, be equipped with third scale 2 and short scale 203 and fourth scale 202 and the horizontal side 202 and the fourth scale 202 and the lower side of long chi 1 establish in proper order.

In this embodiment, the sliding block 3 is made of transparent plastic material, and the protrusion 6 and the sliding block 3 are integrally formed.

In this embodiment, the first scale 101 is a common centimeter scale for measuring length and distance; the second scale 102 is used for measuring latitude minute-second values on the map, and has 12 grids, wherein each grid is based on the area 1: taking latitude scores of 5 ten thousand of topographic maps as unit standards, and marking the latitude scores into 60 equal scores; the third scale 201, the fourth scale 202 and the fifth scale 203 are all used for measuring the minute-second value of longitude on the topographic map, and the third scale, the fourth scale and the fifth scale are all used for measuring the minute-second value of longitude on the topographic map according to different regions 1 in China: the longitude scores of 5 ten thousand topographic maps are marked by unit standard (such as lambda =27mm, lambda =28mm and lambda =29 mm); according to the measurement requirement, the second value of the geographic coordinate of a certain point on the topographic map can be rapidly measured by utilizing the sliding of the short ruler on the long ruler and matching with the reading on each scale, so that the measurement efficiency is greatly improved.
