Description

Sample frame

Technical Field

The utility model relates to a sampling device for the sample is selected and is measured mainly relates to a sample frame.

Background

When developing field ecological tests, researchers often need to select a plurality of 1m × 1m or 50cm × 50cm samples for investigating ecological relevant indexes such as biodiversity or biomass. In the past, researchers often adopt a sample frame made of aluminum alloy and fixedly connected with four sides, or directly adopt an iron stick or a wood stick to circle a place with the square meter of 1 square meter (the sample is called as the sample in ecology), and then survey and measure related ecological test indexes. After looking up the prior patent and literature data, the four frames of the sample square frame are connected end to end mainly in a fixed mode (welding and riveting), or are not connected at all, and a sample square area is formed basically intuitively. The existing sample square frame has the defects of large volume, heavy weight, easy damage of a connecting part, inaccurate sample square measuring amount and the like; especially for some sample prescriptions containing relatively tall plants, the prior sample prescription frame is very inconvenient to use, and the accuracy of the test result is directly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure uses convenient to carry's appearance square frame.

The utility model discloses a sample square frame comprises a plurality of branch pipe end to end connections, each branch pipe include the body of iron and install in the magnet head of body one end, the magnet head of body is used for adsorbing adjacently the other end of body to this a plurality of branch pipe end to end connections form sample square frame, still be provided with the telescopic support that is used for supporting the body on the body.

The utility model discloses a kind square frame, wherein, the body includes first body and telescopically installs the second body in first body, the lateral wall of first body and second body all is provided with the scale mark, the magnet head sets up in the top of second body, the support articulates on first body.

The utility model discloses a appearance square frame, wherein, the magnet head articulates in the top of second body, the side of magnet head is provided with the recess, be used for with adjacent the other end of body cooperatees.

The utility model discloses a sample square frame uses more conveniently, and easy separation is dismantled after using, is difficult to lead to destroying because of the collision in the transportation.

Detailed Description

As shown in fig. 1, fig. 2, fig. 3, fig. 4, the utility model discloses a kind square frame comprises a plurality of branch pipes 1 end to end connection, and each branch pipe 1 includes the body of iron and install in the magnet head 2 of body one end, the magnet head 2 of body is used for adsorbing adjacently the other end of body to this a plurality of branch pipes end to end connection form kind square frame, still is provided with the telescopic support 5 that is used for supporting the body on each body.

The utility model discloses a kind square frame, wherein, the body includes first body 11 and telescopically installs second body 12 in first body, and first body 11 all is provided with the scale mark with the lateral wall of second body 12, magnet head 2 sets up in the top of second body 12, and first body 11 is used for being connected with the magnet head of adjacent branch pipe. The support 5 is hinged to the first tube 11. The lower end of the support 5 is provided with a cone for drilling down the ground. Support 5 articulates on first body 11 through bolt and nut, can connect when needing, then adjusts to suitable high use, then need not connect when not needing.

The utility model discloses a kind square frame, wherein, magnet head 2 articulates in the top of second body, and the side of magnet head is provided with recess 3 for cooperate with the other end of adjacent body.

The utility model discloses a kind square frame, wherein, magnet head 2 is regular triangle, and magnet head 2 passes through the linking arm and articulates on the top of second body 12, and magnet head 2 can be around the top swing of second body 12, and the recess of the side of magnet head can hold the outer end of the first body of adjacent branch pipe. The design can be more convenient dismantlement, equipment sample frame.

The utility model discloses a sample square frame compares the sample square frame of couple formula, and it is more convenient to use, is difficult to lead to destroying because of the collision in the transportation moreover. The bracket enables the sample square frame to be fixed on the ground more stably and conveniently.

The utility model discloses a kind square frame, second body 12 set up in first body 11 telescopically, and the lateral wall of first body and second body all is provided with the scale mark, and such kind square frame can satisfy the demand of multiple kind square area simultaneously.

The utility model discloses a sample square frame can install the LED lamp on the surface of branch pipe.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
