Description
Technical field
The utility model relates to surveying and mapping tool fields, relate in particular to a kind of engineering mapping survey pin.
Background technique
Survey pin is made of thick iron wire, the ruler number of segment that survey pin is mainly used to the position of calibration scale section point and calculating is measured.In work
Survey pin uses very extensive in journey mapping.Existing survey pin design comparison is traditional, only top pole annular in shape, survey pin
Bottom is equipped with the non-return spine of hangnail shape, and non-return spine can prevent survey pin from extracting ground easily by external force, to avoid wind-force or
The influence of other external force causes survey pin insertion ground depth to change and influence engineering mapping precision.Existing survey pin is only to set
Counted fixed non-return spine, after causing in insertion soil, non-return spine can not be unfolded, this will lead to survey pin by wind-force or
The influence of other external force can be pulled up a little, influence mapping precision.
Utility model content
The utility model is designed to pricker cylinder and core bar mainly solving the technical problems that provide a kind of engineering mapping survey pin
Double-layer structure installs non-return spine in core bar bottom, after being inserted into soil, can hold holding rod and up pull up core bar, allow non-return spine exhibition
It opens, pricker cylinder can be effectively prevent to be influenced by wind-force or other external force and is pulled up.
To achieve the above objectives, the present invention provides the following technical solutions:
The engineering mapping survey pin includes the pricker cylinder of tubular, and pricker cylinder surface is carved with scale, is equipped with round bar shape inside pricker cylinder
Core bar, the length of core bar is bigger than the length of pricker cylinder, and the diameter of core bar is equal to the internal diameter of pricker cylinder, and one end of core bar is vertically equipped with directly
Rod-shaped holding rod, the other end of core bar are symmetrically provided tiltedly with the non-return spine of several reversed acanthoids, side of the pricker cylinder close to holding rod one end
The vertical grip ring for being equipped with two annulars.
As advanced optimizing for the technical program, the pricker cylinder and grip ring are manufactured from aluminum alloy, and pricker cylinder and grip ring are equal
Pass through welded connecting.
As advanced optimizing for the technical program, the core bar, non-return spine, holding rod are made of stainless steel, and core bar is logical
Welding is crossed to connect with non-return spine and holding rod.
Be using the beneficial effect of above technical scheme: the engineering mapping survey pin when in use can first two hands difference hand
Pricker cylinder, core bar, non-return spine are inserted into underground appropriate depth by holding rod and grip ring, and then hands grasping holding rod, pulls up core upwards
Bar proper height is all unfolded by the non-return spine of core bar bottom, the engineering mapping survey pin ancillary works can be used to survey and draw work
Make.The engineering mapping is designed to pricker cylinder and core bar double-layer structure with survey pin, installs non-return spine in core bar bottom, after being inserted into soil,
Holding rod can be held and up pull up core bar, allow non-return spine be unfolded, can effectively prevent pricker cylinder by wind-force or other external force influenced and by
It pulls up.
Detailed description of the invention
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is a kind of main view of engineering mapping survey pin of the utility model；
Fig. 2 is a kind of left view of engineering mapping survey pin of the utility model.
Wherein, 1-pricker cylinder, 2-core bars, 3-non-return spine, 4-holding rods, 5-grip rings, 6-scales.
Specific embodiment
A kind of preferred embodiment of engineering mapping survey pin that according to the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 and Fig. 2 shows a kind of specific embodiment of engineering mapping survey pin of the utility model:
The engineering mapping survey pin includes the pricker cylinder 1 of tubular combined with Figure 1 and Figure 2, and scale 6, pricker are carved in 1 surface of pricker cylinder
1 inside of cylinder is equipped with the core bar 2 of round bar shape, and the length of core bar 2 is bigger than the length of pricker cylinder 1, and the diameter of core bar 2 is equal to the interior of pricker cylinder 1
Diameter, one end of core bar 2 are vertically equipped with the holding rod 4 of direct rod shape, and the other end of core bar 2 is symmetrically provided tiltedly with the non-return of several reversed acanthoids
Spine 3, pricker cylinder 1 are vertically equipped with the grip ring 5 of two annulars close to the side of 4 one end of holding rod.
Pricker cylinder 1 and grip ring 4 are manufactured from aluminum alloy, and hardness is big, wear-resistant, corrosion resistance and good, and pricker cylinder 1 and grip ring 4 are equal
Pass through welded connecting.Core bar 2, non-return spine 3, holding rod 5 are made of stainless steel, sturdy and durable, and corrosion resistance is good, core bar
2 are connect by welding with non-return spine 3 and holding rod 5.
The engineering mapping with survey pin when in use can first two hand hold holding rod 4 and grip ring 5 respectively, by pricker cylinder 1, core bar 2,
Non-return spine 3 is inserted into underground appropriate depth, then hands grasping holding rod 4, pulls up 2 proper height of core bar upwards, by 2 bottom of core bar
The all expansion of non-return spine 3, allow 3 inner wall of non-return spine to be bonded with 1 bottom surface of pricker cylinder, non-return spine 3 effectively prevent 2 quilt of pricker cylinder 1 and core bar
It pulls up, the engineering mapping survey pin ancillary works mapping operations can be used.The engineering mapping is designed to pricker cylinder 1 and core with survey pin
2 double-layer structure of bar installs non-return spine 3 in 2 bottom of core bar, after being inserted into soil, can hold holding rod 4 and up pull up core bar 2, allow only
It returns spine 3 to be unfolded, pricker cylinder 1 can be effectively prevent to be influenced by wind-force or other external force and be pulled up.
The above are merely preferred embodiments of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this
The protection scope of utility model.
