Description
[technical field]
The utility model relates to a kind of guiding rulers, and in particular to a kind of folding guiding ruler belongs to building Instrument technology field.
[background technique]
Guiding ruler is mainly used on construction project, for checking there is large surface area, while having the building of flatness requirement again
Metope, traffic municipal administration road surface, works surface etc..According to code requirement, guiding ruler generally requires 2~3 meters of length, so carries non-
Often inconvenience, especially traffic municipal project, route is very long, and detection instrument is all often to be transported by vehicle from a test point
To next test point, general automobile is all difficult to fill in 3 meters of guiding ruler.
Therefore, existing to overcome in order to solve the above technical problems, it is necessory to provide a kind of folding guiding ruler of innovation
The defect in technology.
[utility model content]
To solve the above problems, the purpose of this utility model is to provide a kind of structure is simple, it is easy to use, it is easy to carry
Folding guiding ruler.
To achieve the above object, the technical solution that the utility model is taken are as follows: a kind of folding guiding ruler comprising long
Ruler, short ruler and rotation ruler；Wherein, the long ruler, rotation ruler and short ruler are successively articulated, and three's height is identical；The rotation
Turn ruler length and be equal to height, top is equipped with the semi-circular arc face that radius is mid-height, is connected below semi-circular arc face
First vertical plane of 1/2 guiding ruler height；1/4 arc surface, 1/4 circle are correspondingly provided on the long ruler and short ruler of semi-circular arc face two sides
Second vertical plane of the 1/2 guiding ruler height that is connected below cambered surface；The center point of the semi-circular arc face and 1/4 arc surface is set respectively
There is a shaft；The long ruler is connected with rotation ruler by first connecting rod；The short ruler passes through the second connecting rod phase with rotation ruler
Even；The first connecting rod and the second connecting rod are respectively pivoted in shaft.
The folding guiding ruler of the utility model is further arranged to: first vertical plane can offset with the second vertical plane
It connects.
The folding guiding ruler of the utility model is further arranged to: the long ruler, short ruler are below the shaft
Equipped with locating convex block, the lower edge of the first connecting rod and the second connecting rod can be resisted against on locating convex block, make the first connection
Bar and the second connecting rod are in a straight line.
The folding guiding ruler of the utility model is further arranged to: the long ruler length is equal to rotation ruler length and short ruler
The sum of length.
The folding guiding ruler of the utility model is also configured to: the end of the first connecting rod and the second connecting rod is half
Arc surface, the radius of the semicircle cambered surface are the 1/2 of first connecting rod and the second connecting rod height.
Compared with prior art, the utility model has the following beneficial effects:
It, can by the effect of rotation ruler and the first and second connecting rod 1. the folding guiding ruler structure of the utility model is simple
To open when in use, become the complete guiding ruler that a length is met the requirements, is not desired to require in use, can fold, after folding
Length be raw footage half, to be convenient for carrying.And guiding ruler bottom surface is able to maintain on a horizontal plane.
2. the folding guiding ruler of the utility model is opened into horizontal from folded state, because of the setting of arc surface, make
Three parts of guiding ruler can be successfully around circular rotatable, while because the vertical plane of long ruler, rotation ruler, short ruler end part is deposited
, when face perpendicular to one another is affixed, guiding ruler be in integral level.
3. the locating convex block on the folding guiding ruler of the utility model, which can limit guiding ruler each section, reaches horizontality
Excessive rotation afterwards, playing prevents guiding ruler after folded state opening, because accidentally excessively rotation causes guiding ruler to occur to user
The generation of bending or end damage.
[Detailed description of the invention]
Fig. 1 is the use state diagram of the folding guiding ruler of the utility model.
Fig. 2 is the folding guiding ruler folded state schematic diagram of the utility model.
[specific embodiment]
Please refer to shown in Figure of description 1 and attached drawing 2, the utility model be a kind of folding guiding ruler, by long ruler 1,
A few part compositions such as short ruler 2 and rotation ruler 3.
Wherein, the long ruler 1, rotation ruler 3 and short ruler 2 are successively articulated, and three's height is identical, after guiding ruler is unfolded,
Long ruler 1, rotation ruler 3 and short ruler 2 can be in same levels.1 length of long ruler is equal to rotation 3 length of ruler and short 2 length of ruler
The sum of, make folded concordant by ruler end part.
3 length of rotation ruler is equal to height, and top is equipped with the semi-circular arc face 31 that radius is mid-height, semicircle
First vertical plane 32 of the 1/2 guiding ruler height that is connected below shape arc surface 31.
1/4 arc surface 13,23 is correspondingly provided on the long ruler 1 and short ruler 2 of 31 two sides of semi-circular arc face.1/4 arc surface 13,
Second vertical plane 14,24 of the 1/2 guiding ruler height that is connected below 23.First vertical plane 32 can hang down after guiding ruler expansion with second
14,24 are faced directly to abut against.When guiding ruler is opened into horizontal from folded state, because the arc surface of semi-circular arc face 31 and 1/4 13,
23 setting allows three parts of guiding ruler successfully around circular rotatable, while because of long ruler 1, rotation ruler 3,2 end of short ruler
Vertical plane 14,24 presence, when face 14,24 perpendicular to one another is affixed, guiding ruler be in integral level.
The center point of the arc surface of semi-circular arc face 31 and 1/4 13,23 is respectively equipped with a shaft 4.The long ruler 1 with
Ruler 3 is rotated to be connected by first connecting rod 11；The short ruler 2 is connected with rotation ruler 3 by the second connecting rod 21.Described first connects
Extension bar 11 and the second connecting rod 21 are respectively pivoted in shaft 4, to enable 2 flexible rotating of long ruler 1 and short ruler.Described first
The end of connecting rod 11 and the second connecting rod 21 is semicircle cambered surface 111,211, and the radius of the semicircle cambered surface 111,211 is first
The 1/2 of 21 height of connecting rod 11 and the second connecting rod.
Further, the long ruler 1, short ruler 2 are being equipped with locating convex block 22 below the shaft 4, and described first connects
Extension bar 11 and the lower edge of the second connecting rod 21 can be resisted against on locating convex block 22, make first connecting rod 11 and the second connecting rod 21
In a straight line, prevent guiding ruler after folded state opening, because accidentally excessively rotation causes guiding ruler to bend to user, or
The generation of end damage.
Above specific embodiment is only the preferred embodiment of this creation, all in this wound not to limit this creation
Any modification, equivalent substitution, improvement and etc. done within the spirit and principle of work, should be included in this creation protection scope it
It is interior.
