Description
Technical field
The utility model belongs to the design and manufaction technical field of grassplot resource and ecology investigation apparatus, particularly relates to a kind of Portable detachable sample prescription frame.
Background technology
In the work such as grassplot resource and ecology investigation, the acquisition of grassland vegetation quantitative data, in order to the relevant data message such as bio distribution quantity in institute survey area can be obtained by fast fetching, usually need in regulation area, to carry out investigation and sampling with sample prescription.At present, the orientation of sample prescription determined again by sample prescription after arranging and generally adopting the instrument such as tape measure, lining rope to measure a back gauge at the scene, then measure another back gauge of sample prescription, measure out the four edges of sample prescription one by one, be coiled into pros, as selected regulation area, then sample in area.The sample prescription that this method is determined, boundary line and orientation are not easy accurate control, and the sample prescription boundary line of setting can be caused not close, and sample prescription is irregular, easily cause enquiry data inaccurate, and setting up procedure is more loaded down with trivial details, and field study work efficiency is not high.Design used steel bar welding to make fixing sample prescription frame again afterwards, but such sample prescription frame carries inconvenience.
Utility model content
The utility model is for prior art above shortcomings, and provide the novel portable sample prescription frame of one, boundary line and orientation easily accurately control, and the sample prescription boundary line of setting closes, sample prescription regular shape, and carry, dismantle, easy to assembly.
The purpose of this utility model is achieved through the following technical solutions: a kind of Portable detachable sample prescription frame, comprise large connecting link such as four grades, with externally threaded wing bolt and four right-angle connectors, described right-angle connector arranges and is with female screw, described wing bolt and screw adapt; Connecting link and right-angle connector are interconnected to form foursquare sample prescription frame, and are fixed on right-angle connector by butterfly-type bolt by connecting link; Arrange respectively in described intermediate point both sides, connecting link side and be symmetrical arranged jack, the arc shaped handle with grafting pin is plugged on connecting link by jack, and grafting pin matches with jack, and grafting pin can rotate in jack.Described connecting link, right-angle connector and bowhandle are that aluminum or plastic material are made.
The utility model beneficial effect: simple and reasonable, easy to assembly, quick detachable, carry also very convenient.Can with demand Quick Acquisition 1 m
2, conveniently get 0.5m
2or 0.25 m
2sample, improve field study efficiency, reduce research cost, sample prescription frame can not disassemble by the used time, easily carries, and sample box border rule, can ensure the accuracy of enquiry data.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the main TV structure schematic diagram of the utility model; Fig. 2 is the main TV structure schematic diagram of wing bolt 4 in utility model.
Embodiment
Embodiment 1, a kind of Portable detachable sample prescription frame, as shown in Figure 1, comprise large connecting link 1 such as four grades, with externally threaded wing bolt 4 and four right-angle connectors 2, described right-angle connector 2 is arranged and is with female screw 3, described wing bolt 4 and screw 3 adapt; Connecting link 1 and right-angle connector 2 are interconnected to form foursquare sample prescription frame, and are fixed on right-angle connector 2 by butterfly-type bolt 4 by connecting link 1; Arrange respectively in described intermediate point both sides, connecting link 1 side and be symmetrical arranged jack, the arc with grafting pin is carried 5 hands and is plugged on connecting link 1 by jack, and grafting pin matches with jack, and grafting pin can rotate in jack.Described connecting link 1, right-angle connector 2 and bowhandle 5 are made for aluminum or plastic material.
During use, connecting link inserts right-angle connector hollow parts, then fix with wing bolt, just form a foursquare investigation sample prescription frame after such four bar shaped connecting links, four right-angle connectors, four butterfly-type bolt-connections are fixing, then bowhandle is inserted and connecting link can close bowhandle carry.Simple and convenient assembly, can assemble rapidly in the wild, disassemble, and can improve the work efficiency of field sampling, easy to carry, makes simple.
Claims (2)
1. a Portable detachable sample prescription frame, comprise large connecting link such as four grades, with externally threaded wing bolt and four right-angle connectors, it is characterized in that: to arrange on described right-angle connector and be with female screw, described wing bolt and screw adapt; Connecting link and right-angle connector are interconnected to form foursquare sample prescription frame, and are fixed on right-angle connector by butterfly-type bolt by connecting link; Be symmetrical arranged jack respectively in described intermediate point both sides, connecting link side, the arc shaped handle with grafting pin is plugged on connecting link by jack, and grafting pin matches with jack, and grafting pin can rotate in jack.
