The utility model has the following contents:

an object of the utility model is to provide a portable removable appearance square frame that conveniently carries and uses.

The utility model discloses by following technical scheme implement:

a portable detachable sample square frame comprises four straight frames which are the same in length and are arranged in a square in an enclosing mode, and the adjacent straight frames are connected through connecting elbows; the straight frame comprises a plurality of sub-frames with the same length, every two adjacent sub-frames are connected through a connecting sleeve, and two ends of each sub-frame are inserted into the connecting elbows or the connecting sleeves.

Preferably, the sub-frame, the connecting sleeve and the connecting elbow are all made of plastic.

Preferably, a telescopic leg is fixed at the lower end of each connecting elbow, and a reinforcing claw is fixed at the bottom of each telescopic leg.

Preferably, a horizontally rotating wire wheel is fixed in the middle of the top end of each connecting sleeve, and a magnet is fixed at the end part of a pull rope of each wire wheel; the magnets which are arranged on the straight frames in parallel and are opposite to each other are attracted with each other by the corresponding magnets on the connecting sleeve.

Preferably, the sub-frame is connected with the connecting elbow and the connecting sleeve through threads.

The utility model has the advantages that: the length of each sub-frame is the same, the sub-frames can be assembled according to actual requirements, the sub-frames and the connecting sleeves are sequentially arranged, the sub-frames are inserted into the connecting sleeves, the use is flexible, the sub-frames can be assembled according to actual conditions, and each door component is small in size and convenient to carry; and through setting up the long magnet of line wheel and line wheel stay cord, all drawing good back at per two corresponding stay cords, can divide into the square that sub-frame, connecting sleeve and connecting bend constitute into big squares such as a plurality of little square frame areas, make things convenient for random sampling, it is more convenient to use.

Description of the drawings:

fig. 1 is a schematic structural diagram of the present invention;

FIG. 2 is a schematic structural view of the connecting sleeve of the present invention;

fig. 3 is a schematic structural view of the connecting elbow of the present invention.

In the figure: straight frame 1, sub-frame 1.1, connecting sleeve 1.2, connecting elbow 2, flexible landing leg 3, reinforcement claw 4, line wheel 5, stay cord 5.1, magnet 6.

The specific implementation mode is as follows:

as shown in fig. 1 to 3, a portable detachable sample square frame comprises four straight frames 1 which have the same length and are arranged in a square, and the adjacent straight frames 1 are connected through connecting elbows 2; the straight frame 1 comprises a plurality of sub-frames 1.1 with the same length, every two adjacent sub-frames 1.1 are connected through a connecting sleeve 1.2, and two ends of each sub-frame 1.1 are inserted into the connecting elbows 2 or the connecting sleeves 1.2;

the length of each sub-frame 1.1 is the same, the sub-frames can be assembled according to actual requirements, the sub-frames 1.1 and the connecting sleeves 1.2 are sequentially arranged, and the sub-frames 1.1 are inserted into the connecting sleeves 1.2; after the straight frame 1 is assembled, the two ends of the straight frame are respectively inserted into the connecting elbows 2 to form a square frame; the use is flexible, the assembly can be carried out according to the actual condition, the size of each component is small, and the components are carried in a box;

in order to ensure the service life, the sub-frame 1.1, the connecting sleeve 1.2 and the connecting elbow 2 are all made of plastics, and the sub-frame is small in mass and convenient to carry;

a telescopic supporting leg 3 is fixed at the lower end of each connecting elbow 2, and a reinforcing claw 4 is fixed at the bottom of each telescopic supporting leg 3; when carrying out actual sampling, different vegetation has different heights, will consolidate claw 4 and insert soil in, adjust the height of flexible landing leg 3, and then adjust the height of square frame, ensure that all vegetation all in the square frame that comprises sub-frame 1.1, connecting sleeve 1.2 and connecting elbow 2.

A horizontally rotating wire wheel 5 is fixed in the middle of the top end of each connecting sleeve 1.2, and a magnet 6 is fixed at the end part of a pull rope 5.1 of each wire wheel 5; the magnets 6 corresponding to the connecting sleeves 1.2 oppositely arranged on the straight frames 1 arranged in parallel attract each other, and the rotating shaft of the wire wheel 5 is provided with a torsion spring which can be automatically retracted;

in practical use, random sampling is needed to be carried out on vegetation in the same sampling area, so that a square frame formed by the sub-frame 1.1, the connecting sleeve 1.2 and the connecting elbow 2 is needed to be divided into a plurality of squares with equal areas; pulling the pull ropes 5.1 to pull up the corresponding pull ropes 5.1, so that the magnets 6 on the two pull ropes 5.1 are attracted to form a straight line; after each two corresponding pull ropes 5.1 are pulled, the square frame formed by the sub-frame 1.1, the connecting sleeve 1.2 and the connecting elbow 2 can be divided into a plurality of squares with equal areas, so that random sampling is facilitated;

because the length of each sub-frame 1.1 is equal, and the length of the connecting sleeve 1.2 is also equal, the distance between two adjacent pull ropes 5.1 on the same straight frame 1 is equal, and therefore, after the magnets 6 on all the pull ropes 5.1 are attracted with the magnets 6 on the corresponding pull ropes 5.1, the area of each square formed is equal to the size of the square;

sub-frame 1.1 and connecting elbow 2 and connecting sleeve 1.2 pass through threaded connection, through setting up the screw thread, ensure in the in-service use process, sub-frame 1.1 with connect elbow 2 and connecting sleeve 1.2 separation that can not be easily, guarantee the result of use.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
