Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Present embodiment discloses a kind of positioning rules convenient for construction budget, as shown in Figure 1 and Figure 2, including main scale 1 and backplate
2, main scale 1 is equipped with the first graduation mark 3, and backplate 2 is made of acrylic board.The right side of backplate 2 be equipped with locating slot 4, main scale 1
In in locating slot 4.The light transmittance of acrylic board is up to 92% or more and has excellent weatherability, and anti-aging property is good, has just
The effect of the first graduation mark 3 is observed in people.The upper end of main scale 1 is equipped with location hole 5, and the upper end of backplate 2, which is equipped with, runs through locating slot 4
Connecting hole 6, the position of connecting hole 6 and location hole 5 is corresponding.Positioning bolt 7, the bar portion of positioning bolt 7 are equipped in connecting hole 6
It is equally spaced along its length there are three fixation hole 8, is equipped with positioning member in one of fixation hole 8.
As shown in Figure 2 and Figure 3, positioning member includes fixed link 9, limited block 10 and two elastic slices 11, and fixed link 9 includes living
Motion block 12 and extension block 13, movable block 12 are located at the left side of extension block 13.Limited block 10 is fixed on the right side of extension block 13, limit
The diameter of position block 10 is greater than the diameter of fixation hole 8, and two elastic slices 11 are from the left end of extension block 13 towards side away from each other
Extend.Movable block 12 is equipped with screw hole 14 close to the one side of extension block 13, and extension block 13 is equipped with screw rod close to the one side of movable block 12
15, screw rod 15 is threadedly coupled with screw hole 14.
As shown in Figure 2 and Figure 3, when people store main scale 1, main scale 1 is turned in locating slot 4, is then prolonged by rotation
The length that stretching block 13 makes screw rod 15 expose screw hole 14 changes, so that the length of fixed link 9 is equal to the diameter of positioning bolt 7.
Then by two elastic slices 11 to close to the mobile diameter for making the distance between its be less than fixation hole 8 in mutual side, while by bullet
Piece 11 be pierced by with fixation hole 8 similar in the rear end face of backplate 2 so that fixed link 9 is located in the fixation hole 8.Then elastic slice is unclamped
11, two elastic slices 11 are mobile to side away from each other under the action of natural resiliency, so that fixed link 9 be made to be not easy to far from solid
The side for determining hole 8 is mobile, and main scale 1 and backplate 2 closely connection and are located in locating slot 4 at this time so that the first graduation mark 3 be not easy by
It scratches, extends the service life of main scale 1.
As shown in Figure 2 and Figure 3, the left side of two elastic slices 11 and the junction of one side away from each other are equipped with chamfering 16,
The spring 17 for driving it mobile to side away from each other is equipped between two elastic slices 11.Chamfering 16 reduces 11 left end of elastic slice
Cross-sectional area plays the role of guiding when elastic slice 11 is inserted into fixation hole 8.When elastic slice 11 is pierced by fixation hole 8, elastic slice is unclamped
11, two elastic slices 11 are mobile to side away from each other under the elastic force effect of spring 17 and the elastic reaction of itself, spring 17
The elasticity effect of elastic slice 11 is increased, so that elastic slice 11 remains to work normally when elasticity reduces after long-term use.
As shown in Figure 1, the lower end surface of backplate 2 is fixed with glove block 18, object placing cavity 19, object placing cavity 19 are equipped in glove block 18
Opening towards right side.When people need while storing main scale 1 and pen, pen can be placed in object placing cavity 19 and make pen cap card
It closes on the side wall of object placing cavity 19, the storage effect of backplate 2 is improved, so that pen will not be moved arbitrarily, when pen cap being avoided to fall off
Pen tip scratches backplate 2.
As shown in Figure 1, the front inner wall of locating slot 4 is equipped with the second graduation mark 20, the second graduation mark 20 is close to locating slot 4
Left side.When people need to measure the length of the object of both direction, can first main scale 1 and backplate 2 be respectively moved to and be needed
The corresponding position of the object to be measured, then by the length value in one direction of the first graduation mark 3 reading, pass through the second graduation mark
20 read the length value in another direction, so that people improve measurement efficiency without repeatedly mobile main scale 1.
As shown in Figure 1, the front side wall of backplate 2 is equipped with circumferentially distributed third graduation mark 21, the circle of third graduation mark 21
The heart is identical as the center of circle of connecting hole 6.The front end face of backplate 2 is fixed with the fixed ring 22 concentric with connecting hole 6, and fixed ring 22 is located at
21 outside of third graduation mark.When people need measurement angle, main scale 1 and backplate 2 are adjusted to the angle measured with needs
Parallel position is distinguished on two sides, then by 21 reading angular numerical value of third graduation mark, so that people are without carrying angle measurement
Tool.Fixed ring 22 is raised in backplate 2 and plays the role of protecting third graduation mark 21, so that third graduation mark 21 is not easy to be scraped
Flower.
The working principle of the present embodiment: when people store main scale 1, positioning bolt 7 is first passed through into connecting hole 6 and location hole
5, then main scale 1 is turned in locating slot 4 with positioning bolt 7 for the center of circle.Then expose screw rod 15 by rotating extension block 13
The length of screw hole 14 changes until the length of fixed link 9 is equal to the diameter of positioning bolt 7, then by two elastic slices 11 to leaning on
Nearly mutual side is mobile, so that the distance between elastic slice 11 is less than the diameter of fixation hole 8, while elastic slice 11 being passed through and backplate
In fixation hole 8 similar in 2 trailing flank.When limited block 10 is abutted with positioning bolt 7, elastic slice 11 is unclamped, two elastic slices 11 exist
It is mobile to side away from each other under the action of spring 17 and its own elasticity, so that it is fixed on fixed link 9 in fixation hole 8,
And then make the fixed close connection to realize main scale 1 and backplate 2 in the position of positioning bolt 7.Main scale 1 is located in locating slot 4 and makes
First graduation mark 3 avoids the first graduation mark 3 from being scratched by article, extends the service life of main scale 1 outside being not exposed to.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
