Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, a portable style box for field survey in forestry according to a first embodiment of the present invention includes a plurality of connection pipes 110 and connection ropes 120.

The connecting rope 120 connects the plurality of connecting pipes 110 end to end in series to form a rectangular frame, and as shown in fig. 1, the connecting rope 120 sequentially passes through the centers of the four connecting pipes 110 and is knotted to connect the connecting pipes 110 in series. The connecting pipe 110 is preferably made of a PVC material, is light in weight, convenient to carry and low in cost, and the connecting pipe 110 can be set with specifications of different lengths according to requirements so as to meet the requirements of different size samples.

In order to ensure that the connecting pipes 110 are connected in series, the connecting pipes are perpendicular in angle and axially positioned, one end of each connecting pipe 110 is provided with a supporting plate 111 matched with the profile of the connecting pipe 110, the supporting plate 111 is an arc-shaped plate, the diameter of the inner ring of the supporting plate is the same as that of the connecting pipe 110, and the extending direction of the supporting plate 111 is perpendicular to the length direction of the connecting pipe 110, so that when the adjacent connecting pipes 110 are attached to the inner rings of the supporting plates 111, the adjacent connecting pipes 110 can be ensured to.

The supporting plate 111 is provided with an annular cutting groove 114 in the middle, and one end of each connecting pipe 110 away from the supporting plate 111 is provided with a flange 115 correspondingly matched with the annular cutting groove 114.

The connection between the adjacent connecting pipes 110 is as shown in fig. 3, the outer wall of the connecting pipe 110 is attached to the supporting plate 111 of the adjacent connecting pipe 110 and the connection is limited by the flange 115 embedded in the circular cut groove 114, i.e. the flange 115 at one end of each connecting pipe 110 is clamped into the circular cut groove 114 of the adjacent connecting pipe 110, and the circular cut groove 114 at the other end is matched with the flange 115 of the other adjacent connecting pipe 110, thereby realizing end-to-end connection. In order to achieve a more stable connection, it is preferable that the ring slot 114 is connected with the flange 115 by an interference fit, so that the flange 115 can be clamped into the ring slot 114 to achieve a fixed connection under a slight force.

In order to improve the connection stability between the connection pipes 110, the support plate 111 is provided with a first connection hole 112, and the first connection hole 112 extends through and is parallel to the length direction of the corresponding connection pipe 110. One end of the connecting pipe 110, which is far away from the support plate 111, is provided with a second connecting hole 113 corresponding to the first connecting hole 112, and the extending direction of the second connecting hole 113 is parallel to the extending direction of the support plate 111. The second connection holes 113 of the connection pipes 110 are aligned with the first connection holes 112 of the adjacent connection pipes 110 and are equipped with fasteners, preferably pins or bolts, by which the adjacent connection pipes 110 are fixedly connected.

In the second embodiment of the present application, the difference from the first embodiment is that the second embodiment is provided with a structure for facilitating insertion-fixing to the ground. The peripheral wall of the connecting tube 110 is provided with an insertion part 116 extending radially outwards, and the insertion part 116 is perpendicular to the extending direction of the supporting plate 111. As shown in fig. 4, the connection pipe 110 is connected to the frame and then directly inserted into the ground to fix the position of the sample cell, thereby preventing the sample cell from being touched and moved. In order to facilitate the insertion into the ground, the bottom of the insertion part 116 is provided with a chamfer facilitating the insertion into the ground.

The plastic rope is threaded at the hollow part of the PVC pipe, so that the design is flexible and rapid. In the past, one small sample is measured and defined on a multi-purpose tape site, time and labor are consumed, and the sizes of all samples are different. Four PVC pipes with required lengths are selected indoors at present and connected in series by plastic ropes, so that the PVC pipe is foldable, does not occupy too much space, is convenient to use and low in cost and is used for sample survey.

The above embodiments are only used for illustrating the technical solutions of the present invention and are not limited thereto, and any modification or equivalent replacement that does not depart from the spirit and scope of the present invention should be covered by the scope of the technical solutions of the present invention.
