Abstract
A kind of diameter of a cross-section of a tree trunk 1.3 meters above the ground encloses the specific purpose tool that chi relates to a kind of metering tree breast-height diameter for using during forest survey.One end of blade (1) is provided with clamp device, the locking post (3) that this clamp device parallels setting by a chuck (2) and two is formed, chuck (2) is provided with the groove (4) in its front end face opening, chuck (2) offers the chute (5) perpendicular to chuck (2) front end face for fixing and locking post (3) termination respectively on the cell wall of groove (4) both sides, chuck (2) one end is fixedly connected with blade (1) one end, the other end has the stomidium (6) passed for blade (1) free end be communicated with groove (4), two locking posts (3) are fixed in chute (5) respectively by the spring (7) that force direction is relative.It has that structure is simple, lightweight, cost is low, accurate measurement, reliable and easy to use, the advantage of carrying.
Description
Technical field
The utility model relates to and encloses chi, particularly a kind of specific purpose tool of the metering tree breast-height diameter for using during forest survey.
Background technology
Often use in forest survey and enclose the diameter of a cross-section of a tree trunk 1.3 meters above the ground of chi to tree and enter to obtain and measure.Measurement statistics can be carried out to a large amount of arboreal growth situations during measurement.In order to add up the upgrowth situation of same trees at different times tree-walk, will repeat to measure at different times same one tree.The used diameter of a cross-section of a tree trunk 1.3 meters above the ground encloses chi for banded, so that at its surface indicia scale and reading.Its structure is very simple, does not have other additional structures.Existing in using exist following problem with enclosing chi: need two people to coordinate when (1) is measured, need one man operation, people's record, lost labor; One people's complete independently is then inefficent.(2) time to fixed target duplicate measurements, at every turn must manual measurement again, not only lose time but also easily strengthen measuring error.
To this, someone conceives the existing chi that encloses to carry out structure of modification, by chi increasing clamp device it is disposablely fixed on trunk periphery enclosing, just can solve the problem period in different measurements by means of only reading the fixing reading enclosing chi in the tree.But because trees are annual all in growth, how to solve and enclose chi and reliably fix on trunk, clamp device can constantly become large with tree breast-height diameter again and automatically discharge the difficult problem that blade just becomes thorny simultaneously.Because blade is wider, comparatively large with the contact area of trees and clamp device, frictional resistance is also comparatively large, and this just brings difficulty to design.Also blade can be made to produce larger dilatation comparatively greatly with clamp device frictional resistance, the accuracy of impact metering.Further, because forest survey needs the quantity of measurement usually all very large, need to use the quantity of enclosing chi also very huge, width is greatly also unfavorable for weight and the cost of reduction ruler, all brings inconvenience to carrying and using; Enclose that chi is narrower is not easy to again reference mark and reading.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of structure is simple, cost is low, the diameter of a cross-section of a tree trunk 1.3 meters above the ground of accurate measurement and good reliability encloses chi.
Technical solution of the present utility model is: it comprises blade, one end of described blade is provided with clamp device, the locking post that this clamp device parallels setting by a chuck and two is formed, chuck is provided with the groove in its front end face opening, chuck offers the chute perpendicular to chuck front end face for fixing and locking styletable head respectively on the cell wall of groove both sides, chuck one end is fixedly connected with blade one end, the other end has the stomidium passed for blade free end be communicated with groove, two locking posts are fixed in chute respectively by the spring that force direction is relative, the free end of blade passes in " S " sigmoid through two locking intercolumniations under the force of a spring through after the stomidium of chuck.
Technique effect of the present utility model is: it has, and structure is simple, lightweight, cost is low, accurate measurement, reliable and easy to use, the advantage of carrying.Blade is thin, adopts and marks with the colour circle of resistance solid colour, convenient memory and counting.Clamp device simple structure is reliable, and can ensure automatically to discharge blade, accuracy of reading is reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the main TV structure schematic diagram of the utility model clamp device;
Fig. 3 is the plan structure schematic diagram of the utility model clamp device.
Embodiment
As Fig. 1, shown in 2 and 3, it comprises blade 1, one end of described blade 1 is provided with clamp device, the locking post 3 that this clamp device parallels setting by a chuck 2 and two is formed, keep at a certain distance away between two locking posts 3, so that blade 1 can just pass, chuck 2 is provided with the groove 4 in its front end face opening, chuck 2 offers the chute 5 perpendicular to chuck 2 front end face for fixing and locking post 3 termination respectively on the cell wall of groove 4 both sides, chuck 2 one end is fixedly connected with blade 1 one end, the other end has the stomidium 6 passed for blade 1 free end be communicated with groove 4, two locking posts 3 are fixed in chute 5 respectively by the spring 7 that force direction is relative, the free end of blade 1 passes in " S " sigmoid through between two locking posts 3 through after the stomidium 6 of chuck 2 under the acting force of spring 7.Blade 1 is under the effect of two locking posts 3 and spring 7, and bending in " S " shape was both conducive to self-locking, also automatically can expand outwardly with the growth of trees.
The inclined-plane 8 be convenient to blade 1 free end and passed is provided with in described groove 4.This inclined-plane 8 also can be the curved surface of indent, and the blade 1 with certain rigidity is easily passed along it.
Described blade 1 is the rounded restiform bodies in cross section.The width of groove 4 is a bit larger tham the diameter of blade 1 as well.
Described blade 1 is provided with the colour circle for representing long measure.Colour circle can use the representation of resistance colour circle, represents different numerical value and be easy in conjunction with different in width just can be clear by numerical expression concrete for tree-walk with different colors.
