The specific embodiment
Below providing specific embodiment of the utility model further illustrates the technical solution of the utility model.
Defer to technique scheme, as shown in Figures 1 to 5, a kind of three meters rulers comprise surveyors' staff and three meters guide rails 1:
Described three meters guide rails 1 are the inner cuboid guide rail that offers cross chute, cross chute is opened in the inside of cuboid guide rail along the direction on the long limit of cuboid guide rail, the end face that cross chute passes the cuboid guide rail leaves the junction plate 11 be used to being connected the cuboid guide rail with the two ends of Bing Zai bottom surface, bottom surface;
Described surveyors' staff comprises interior bar 3 and overcoat 2, described overcoat 2 is the cuboid slide bar of hollow, in the bottom of cuboid slide bar, be provided with the roller 23 that can roll along the cross chute bottom, the long side direction along the cuboid slide bar on the cuboid slide bar offers interior bar chute 25; At cuboid slide bar top, be provided with magnetic drawing 21, on magnetic drawing 21, be provided with the graduated scale 26 that can move up and down along magnetic drawing 21; Described interior bar 3 is arranged on the inside of overcoat 2, and interior bar 3 is the bar shaped thin bar; The upper end of bar shaped thin bar is provided with the tip 31 that can stay cut on magnetic drawing 21, and the lower end of bar shaped thin bar is consolidated with and interior bar slide block 33 that with described interior bar chute 25 coordinate vertical with the bar shaped thin bar.
Three meters guide rails 1 of this device are the cuboid guide rail, in the cuboid guide rail, offer cross chute, cross chute is comprised of orthogonal upper gliding groove 5 and left and right chute 4, the upper end of wherein going up gliding groove 5 penetrates the end face of cuboid guide rail fully, the lower end major part of upper gliding groove 5 is passed the bottom surface of cuboid guide rail, only at the two ends of cuboid guide rail bottom surface, leaves the junction plate 11 be used to connecting the cuboid guide rail, and the width of junction plate 11 is w, be highly d, as shown in mark in Fig. 1 Fig. 2.
When the structure of three meters guide rails 1 can make surveyors' staff slide in upper gliding groove 5, the interior bar slide block 33 of interior bar 3 in surveyors' staff is stuck in the left and right chute 4 of cross chute, surveyors' staff only can move along the direction of cross chute bottom chute like this; Owing on the overcoat 2 at surveyors' staff, offering interior bar chute 25, in this, bar chute 25 is offered the long side direction of direction along overcoat 2 simultaneously, and when interior bar slide block 33 was slided in cross chute, the overcoat 2 of surveyors' staff can move up and down again.
Surveyors' staff comprises two parts, overcoat 2 and interior bar 3.Overcoat 2 lower ends arrange roller 23, on overcoat 2, also are provided with interior bar chute 25; Interior bar 3 is arranged on overcoat 2 inside, and is fixing by anchor ear 24, by the cooperation of interior bar chute 25 and interior bar slide block 33, interior bar 3 can be moved up and down in overcoat 2; Interior bar 3 is the bar shaped thin bar, and interior bar 3 upper ends are provided with tip 31, and when interior bar 3 moved up and down, tip 31 can stay cut on the magnetic drawing 21 on overcoat 2, and the structure of interior bar 3 as shown in Figure 6.
Described magnetic drawing 21 is commercially available drawing board commonly used, and its principle is when nib is drawn on drawing board, and the material in drawing board middle level is in the same place with the magnetic material of bottom is glutinous, has just produced cut.While not needing this cut, only need to draw clear trace switch 22, make the magnetic material of the material in middle level of drawing board and bottom separately, can reach the purpose of removing cut.
In order to measure the length of cut, on magnetic drawing 21, be provided with the graduated scale 26 that can move up and down along magnetic drawing 21; And on tip 31, be provided with the zeroing cross bar 32, zeroing cross bar 32 is the reference point of graduated scale 26 zeroings, during use, move up and down graduated scale 26, to the scale value of graduated scale 26 for-d place is in sustained height with the cross bar 32 that returns to zero, namely graduated scale 26 has been carried out to " zeroing ".
The use procedure of this device:
During use, three meters guide rails 1 are placed on and need the road surface of measuring, the bottom surface of three meters guide rails 1 is contacted with road surface, then in surveyors' staff being breakked away to cross chute along one of three meters guide rails 1, interior bar slide block 33 is stuck in left and right chute 4, the roller 23 of surveyors' staff this moment bottom, in upper gliding groove 5, has namely touched and has needed the road surface of measuring.
Before measurement, need graduated scale 26 " zeroing ", the scale value that is about to graduated scale 26 is-the d place to aim at the zeroing cross bar 32 on tip 31.After zeroing is good, surveyors' staff is pushed to the other end of three meters guide rails 1 along cross chute, this moment is due to the roller 23 rough bottom surfaces of contact, driving overcoat 2 moves up and down, and interior bar 3 is stuck in left and right chute 4 due to interior bar slide block 33, interior bar 3 can not move up and down, and 31, the tip of interior bar 3 can stay the cut of up and down on magnetic drawing 21.After when surveyors' staff, being pushed to the other end of three meters guide rails 1, record the length of cut on magnetic drawing 21, be the maximal clearance value in this road section scope.
