Embodiment
Referring to figs. 1 through Fig. 6, the portable height of tree survey instrument of a kind of hinged bayonet type, comprise by some bar chi 11 head and the tail and be movably hinged successively the folding rod chi 10 formed, in each bar chi 11 hinged places, be provided with check lock lever chi 11 so that the snap close of folding rod chi 10 in straight configuration is labeled with scale on bar chi 11.
While utilizing this hinged bayonet type height of tree survey instrument to carry out height of tree surveying work, folding rod chi 10 is stretching and make whole folding rod chi 10 keep straight configurations to be positioned over by mangrove by snap close check lock lever chi 11, the height of tree of directly by the scale value on bar chi 11, reading mangrove, simple and quick, after measurement completes, folding rod chi 10 is folded back the length of single bar chi 11, reduce and take up an area space, be convenient for carrying, realize the Mangrove Wetlands measurement height of tree larger in plant growth density, improved the high efficiency of investigation surveying work.
As preferred implementation of the present utility model, but snap close comprises the splined hole 21 of being located at respectively on two adjacent stems chi 11 hinged end and inserts the interior limit rod chi 11 of splined hole 21 bearing pin 20 in relative rotation, be provided with the spline 22 matched with splined hole 21 on bearing pin 20.
As preferred implementation of the present utility model, at the hinged end of each bar chi 11 spaced two the hinged disk ends 12 that stretch out, have corresponding splined hole 21 on two hinged disk ends 12, the splined hole 21 that two adjacent stems chis 11 insert in hinged disk end 12 by bearing pin 20 is hinged, and on bearing pin 20, axially spaced-apart is provided with two and snaps in splined hole 21 with limit rod chi 11 spline 22 in relative rotation.
In the present embodiment, except the first and last barre chi 11, other each bar chi 11 two ends all are provided with hinged disk end 12 to facilitate each bar chi 11 head and the tail hinged formation folding rod chi 10 successively, two hinged disk ends 12 keep at a certain distance away and are arranged on bar chi 11 end one sides, referring to Fig. 2, Fig. 4 and Fig. 6, in two adjacent bar chis 11, the interlaced laminating of two hinged disk ends 12 separately is close together, and make the splined hole 21 in hinged disk end 12 separately corresponding, bearing pin 20 is through each splined hole 21 and then two adjacent bar chis 11 are hinged, the axially spaced-apart of bearing pin 20 is provided with two splines 22, wherein the axial width of spline 22 is half of hinged disk end 12 thickness, when bearing pin 20 during through each splined hole 21 in two bar chis 11, spline 22 can just be stuck on two bar chis 11 in the splined hole 21 in hinged disk end 12 separately, thereby limiting two bar chis 11 relatively rotates, whether the moving left and right of bearing pin 20 can be controlled between the adjacent bar chi 11 of two-phase and can relatively rotate, when folding rod chi 10 during in straight configuration, can lock the position between two adjacent stems chis 11 by mobile bearing pin 20, limiting it relatively rotates.Specifically referring to Fig. 3 to Fig. 6, one of them bar chi 11 in Fig. 3 and Fig. 5 does not draw, the moving left and right can make to latch under locking state and releasing orientation of bearing pin 20 switched, Fig. 3 and Fig. 4 are the schematic diagram of snap close in locking state, when two adjacent stems chis 11 during in straight configuration, bearing pin 20, to a side shifting, just is stuck in the splined hole 21 in two adjacent stems chis 11 spline 22 on bearing pin 20, limits two adjacent stems chis 11 rotations and makes it remain on straight configuration; Fig. 5 and Fig. 6 are the schematic diagram of snap close in releasing orientation, bearing pin 20 is to an other side shifting, half that makes spline 22 on bearing pin 20 breaks away from the splined hole 21 in hinged disk end 12 on one of them bar chi 11, be that splined hole 21 on one of them bar chi 11 does not coordinate with the spline 22 on bearing pin 20, thereby can relatively rotate between two adjacent stems chis 11 to fold, make the whole folding rod chi 10 can be in folded state.
As preferred implementation of the present utility model, at an end of folding rod chi 10, be connected with wrist strap 30.
Can save by wrist strap 30 is set the casing that holds other common height of tree survey instrument, reduced transportation and carried difficulty, more be conducive to field study.
As preferred implementation of the present utility model, bar chi 11 adopts stainless steel material to make.
The above is explained in detail embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-mentioned embodiment, in the ken possessed at described technical field those of ordinary skill, can also under the prerequisite that does not break away from the utility model aim, make various variations.
