[specific embodiment]
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
With novel further description.
Fig. 1-Fig. 3 is please referred to, the utility model provides a kind of criminal scene footprint measuring scale, comprising: use transparent material
The first measuring scale 1 being made and the second measuring scale 2 being sheathed in the first measuring scale 1, described second measuring scale, 2 one end
It is pierced by with the reading starting point flush of the first measuring scale 1, the other end in 1 other end of the first measuring scale, and second measuring scale 2
One end two sides being sheathed in the first measuring scale 1 are respectively equipped with connection strap 3, and one end of the connection strap 3 is connect with the second measuring scale 2
It is integrated, the other end close to the side of the second measuring scale 2 vertically offers a circular hole, is equipped with far from the side of the second measuring scale 2
One protrusion 4, the circular hole is interior to be equipped with a spring 5, and the other end of the spring 5 is fixed on the second measuring scale 2, and described first surveys
It is equipped with the through-hole 6 adaptable with protrusion 4 on the outside of the reading end of gage 1, second measuring scale 2 is another in the first measuring scale 1
After the stretching of end under the action of spring 5, protrusion 4 is pierced by through-hole 6.
Particularly, two lateral edge ruler bodies of second measuring scale 2 are respectively equipped with transparent sliding slot slot 7, set respectively in the sliding slot 7
There is sliding block 8, and second measuring scale 2 is equipped with a measuring block 9, the both ends of the measuring block 9 in the part that is pierced by of the first measuring scale 1
It is fixedly connected respectively with sliding block 8, the measuring block 9 slides under the action of sliding block 8 in sliding slot 7, to measure footprint
Length or width；It is designed in this way, when measuring, the length of footprint can quickly be read out by sliding measuring block 9, from
And measuring speed is improved, while what measuring block can be more accurate navigates to the edge of footprint, to improve footprint measurement
Accuracy.
Particularly, the both ends of first measuring scale 1 and the second measuring scale 2 are respectively arc；It is designed in this way, so that the
The end of one the second measuring scale of measuring scale is more bonded with footprint edge, to further improve the accuracy of footprint measurement.
Particularly, every scale line length on first measuring scale 1 is of same size with the first measuring scale 1, institute
The every scale line length stated on the second measuring scale 2 is of same size with the second measuring scale 2；It is designed in this way, can position
After good footprint, length or width that is more quick and accurately reading out footprint has been saved the time, has been improved work efficiency.
Particularly, the integral multiple that the length of first measuring scale 1 and the extension elongation of the second measuring scale 2 are 1CM；So
Can be to avoid after the second measuring scale to be fully extended, the handover position of the second measuring scale and the first measuring scale is non-whole centimetre, is needed
Very important person is the trouble for calculating margin, to further improve working efficiency.
Particularly, the measuring block 9 is arc, radian and the second radian of the measuring scale 2 far from 1 one end of the first measuring scale
It is equal；It is designed in this way, measuring block can be allow preferably to be bonded with footprint edge, to further increase the standard of footprint measurement
True property.
Particularly, the measuring block 9 is made using deformable aluminum alloy material, and the width of the measuring block 9 is less than
The width of sliding block 8；Be designed in this way, when needing to measure footprint width, can with the radian direction of manual change's measuring block, so as to
Go out the width of footprint, while sliding block Widening Design with rapid survey, improves the service life of sliding block indirectly, anti-limited slip block is because of length
There is loose phenomenon and influences to use in phase sliding.
Application method:
When unused, the second measuring scale is sheathed in the first measuring scale, and spring is in compressive state at this time, when need into
When row footprint measures, the second measuring scale is stretched, when protrusion is moved to lead to the hole site, spring is in extended state, and protrusion is in bullet
It is stretched out under the action of spring in through-hole, the second measuring scale is fully extended at this time, and the first measuring scale, the second measuring scale form a reading
Complete and continuous footprint measuring scale, the at this time end by the first measuring scale far from the second measuring scale and footprint length one end pair
Together, it later by stirring measuring block, moves measuring block along the chute under the action of sliding block, makes the another of measuring block and footprint length
One end alignment, it can the length for reading out footprint artificially exerts a force to measuring block when needing to measure the width of footprint, makes to survey
The radian of end of the radian of gauge block with the first measuring scale far from the second measuring scale is identical, makes the second measuring scale far from first later
The end of measuring scale is aligned with footprint width one end, later by stirring measuring block, makes measuring block under the action of sliding block along cunning
Slot is mobile, is aligned measuring block and the other end of footprint width, it can the length for reading out footprint, after measurement, and pressing
Protrusion, makes spring-compressed, pushes the second measuring scale later, retracts the second measuring scale in the first measuring scale, consequently facilitating carrying.
