Abstract
The utility model relates to the field of teaching appliances and particularly relates to a portable quadrat frame. The portable quadrat frame comprises a base and a connector, wherein the base and the connector are square-shaped, the base is provide with a fixed rod which is 0.5-0.8m long, the fixed rod is internally provided with a telescopic rod which is 0.5-0.8m long, the fixed rod and the telescopic rod are connected by a bolt, the connector is arranged on the telescopic rod, the base and the connector are connected with a strip plate, the middle part of the strip plate is provided with a hinge, and the strip plate is 1m long. The beneficial effects are as follows: the portable quadrat frame is easy to carry, convenient to operate and complete in specifications and can be quickly assembled, both time and labor are saved, the efficiency of field investigation is improved, the investigation cost is reduced, the quadrat frame is easy to carry as the quadrat frame can be decomposed and the telescopic rod can be contracted when the portable quadrat frame is not in use, the boundary of the quadrat frame is regular, the accuracy of survey data can be ensured, and only a small area is needed to store the portable quadrat frame.
Description
Technical field
The utility model relates to the teaching aid field, relates in particular to a kind of portable sample prescription frame.
Background technology
In the field study of plant teaching, agricultural research, in order to obtain fast the various relevant data messages such as biological substep quantity in the institute survey area, usually need to carry out in the regulation area with sample prescription investigation and sampling.At present, sample prescription arranges determines the orientation of sample prescription after the instruments such as general employing tape measure, lining rope have been measured a back gauge of sample prescription at the scene again, then measure another back gauge of sample prescription, measure out one by one the four edges of sample prescription, be coiled into pros, as selected regulation area, then take a sample in area.The sample prescription that this method is determined, boundary line and orientation are not easy accurate control, can cause the sample prescription boundary line of setting not closed, and sample prescription is irregular, easily causes enquiry data inaccurate, and setting up procedure is more loaded down with trivial details, and the 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.
The utility model content
The utility model provides novel a kind of portable sample prescription frame for the prior art above shortcomings, and boundary line and orientation are easily accurately controlled, and the sample prescription boundary line of setting is closed, the sample prescription regular shape, and easy to carry.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of portable sample prescription frame, comprise base, connector, described base and described connector all are square, and described base is provided with fixed bar, the length of described fixed bar is 0.5-0.8m, be provided with expansion link in described fixed bar, the length of described expansion link is 0.5-0.8m, and described fixed bar and described expansion link are bolted, described expansion link is provided with connector, described base all is connected with stripe board with described connector, is provided with hinge in the middle part of described stripe board, and described stripe board length is 1m.
Described stripe board is made by plank.
Described expansion link and described fixed bar are each made of aluminum.
The utility model beneficial effect: easy to carry, easy and simple to handle, complete in specifications, can become the sample prescription frame by rapid-assembling, time saving and energy saving, improve field study efficient, reduce research cost, the used time can not disassemble the sample prescription frame, expansion link shrinks, and easily carries sample prescription edge circle rule, can guarantee the accuracy of enquiry data, the harvesting floor area is little.
Description of drawings
Fig. 1 is portable sample prescription mount structure schematic diagram described in the utility model.
In figure: the 1-base; The 2-connector; The 3-fixed bar; The 4-expansion link; The 5-bolt; The 6-stripe board; The 7-hinge.
Embodiment
The below is described in further detail the utility model according to drawings and embodiments:
as shown in Figure 1, a kind of portable sample prescription frame of the present utility model, comprise base 1, connector 2, described base 1 all is square with described connector 2, described base 1 is provided with fixed bar made of aluminum 3, the length of described fixed bar 3 is 0.5-0.8m, be provided with expansion link made of aluminum 4 in described fixed bar 3, the length of described expansion link 4 is 0.5-0.8m, described fixed bar 3 is connected by bolt 5 with described expansion link 4, described expansion link 4 is provided with connector 2, described base 1 all is connected with stripe board 6 with described connector 2, described stripe board 6 middle parts are provided with hinge 7, described stripe board 6 length are 1m, described stripe board is made by plank.
During use, first by the two piece planks that are opened into an integral body of hinge 7 with stripe board 6, then expansion link 4 is pulled out in fixed bar 3, be to be fixed with bolt 5 after 1m with ruler measurement length, remove like this length of connector 2 and base 1, the sample prescription frame that it is 1m that whole sample prescription frame just forms a length of side, available sample prescription frame carries out corresponding sampling survey.Use and later bolt 5 is unclamped, all flexible in fixed bar 3 expansion link 4, hinge 7 by stripe board 6 middle parts is folded into the less two parts of length with stripe board 6, each edge lengths of sample prescription frame after folding like this will diminish accordingly, can not affect again the normal use of sample prescription frame when being convenient to carry.
Claims (3)
1. portable sample prescription frame, it is characterized in that: comprise base, connector, described base and described connector all are square, described base is provided with fixed bar, the length of described fixed bar is 0.5-0.8m, be provided with expansion link in described fixed bar, the length of described expansion link is 0.5-0.8m, described fixed bar and described expansion link are bolted, described expansion link is provided with connector, described base all is connected with stripe board with described connector, is provided with hinge in the middle part of described stripe board, and described stripe board length is 1m.
