Description

Technical Field

[0001] The utility model relates to the field of customs quarantine equipment, and more specifically to a photographing table for identifying forest pests. Background Art

[0002] As the first line of defense for guarding biological safety, the customs is the first line of defense against the invasion of alien harmful organisms. The customs needs to carry out inspection and quarantine work on the plants and their products entering and leaving the country.

[0003] In daily quarantine, for the identification of insects carried in imported logs, generally, those with a relatively small size can be placed under a microscope for observation and photographing. However, for many insects with a slightly larger size (such as longhorn beetles, buprestids, etc.), the depth of field of the current microscope cannot meet the requirement of taking full - range photos of the important features of the insects. Quarantine personnel can only manually move the test specimens continuously for gradual observation and photographing. However, this operation has two deficiencies. One is that the test specimen is placed on the stage, and the moving direction and range of the stage are limited, and the test specimen may not be fully observed and photographed. The other is that since it is the stage that moves, when the test specimen moves with the stage, on the one hand, it is easy to fall off, and on the other hand, the specimen is easy to be misaligned or damaged, thus affecting the observation and photographing of it.

[0004] Therefore, how to provide a photographing table for identifying forest pests to overcome the above problems is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0025] The present invention discloses a photographing table for identifying forest pests. By designing the stage 2, the forest pests to be identified can be stably placed on the stage 2;

[0026] The semi-circular rod 3 is rotatably installed on the base 1 through the rotating shaft 4 and the support 5. The sliding part 10 is slidably installed on the semi-circular rod 3, and the sliding part 10 can move along the rod length direction of the semi-circular rod 3. The telescopic part is installed on the sliding part 10, and the camera 12 is connected to the telescopic end of the telescopic part; the above design realizes that the forest pests to be identified do not move while the camera 12 moves. While ensuring that the camera 12 can observe the forest pests to be identified reliably and clearly, the forest pests to be identified will not shift or be damaged on the stage 2; on the other hand, the camera 12 can use the semi-circular rod 3, the sliding part 10 and the telescopic part to achieve flexible multi-directional movement. The movement range of the camera 12 is hemispherical, and the stage 2 is at the center of the sphere. The camera 12 can observe and photograph the forest pests to be identified comprehensively and clearly;

The axis line of the first limiting wheels 7 is perpendicular to the axis line of the rotating shaft 4. The geometric centers of the two first limiting wheels 7 and the geometric center of one second limiting wheel 8 can jointly define an isosceles triangle. The outer side walls of the first limiting wheels 7 and the outer side wall of the second limiting wheel 8 respectively roll and abut against the two opposite side walls of the semi-circular rod 3. The first limiting wheels 7 can be located above the second limiting wheel 8, that is, the second limiting wheel 8 is located between the semi-circular rod 3 and the stage 2. The telescopic member is connected to the support frame 6.

[0043] The support frame 6 is provided with a threaded hole 10000, which is located between the two limiting wheels 7. The central axis of the threaded hole 10000 is perpendicular to the axis of the rotating shaft 4, and the plane defined by the central axis of the threaded hole 10000 coincides with the plane defined by the central axis in the rod length direction of the semi-circular rod 3. A tightening screw 16 is screwed into the threaded hole 10000, and the sharp end of the tightening screw 16 can abut against the outer side wall of the semi-circular rod 3; after the support frame 6 moves to a certain position on the semi-circular rod 3, the tightening screw 16 is tightened, and the relative position of the support frame 6 and the semi-circular rod 3 can be fixed, that is, after the tightening screw 16 is tightened, the support frame 6 will no longer move along the rod length direction of the semi-circular rod 3.

[0044] The telescopic member includes a fixing member 9, a sliding member 10 and a pressing bolt 11.

[0045] There are two fixing members 9, both of which are fixed to the support frame 6. Each fixing member 9 is provided with a long hole 90, and the length direction of the long hole 90 is perpendicular to the axis of the rotating shaft 4. The plane defined by the central axis in the rod length direction of the semi-circular rod 3 is parallel to the length direction of the long hole 90.

The two opposite side walls of the rectangular block 1000 are respectively slidably in close contact with the two long hole walls of the long hole 90. Each rectangular block 1000 is provided with a threaded hole 10000.

[0047] One end of the pressing bolt 11 is screwed into the threaded hole 10000 after passing through the long hole 90, and the bolt head of the pressing bolt 11 and the connecting member 100 can jointly clamp the fixing member 9.

[0048] The camera 12 is fixed on the sliding member 10, and the sliding member 10 is located between the camera 12 and the semi-circular rod 3; after the rectangular block 1000 moves to a certain position in the long hole 90, the pressing bolt 11 is tightened. At this time, the rectangular block 1000 cannot continue to move along the length direction of the long hole 90, that is, the relative position between the camera 12 and the semi-circular rod 3 is fixed.

[0049] When the shooting table is in use, in the first step, the forest pest to be identified is placed on the stage 2. If the forest pest is alive, it can be fixed to the stage 2 by using tape or other fixing parts. In the second step, the semi-circular rod 3 is rotated. When the semi-circular rod 3 rotates around the rotating shaft 4 to a certain position, the compression nut 15 is tightened. In the third step, the support frame 6 is moved. After the support frame 6 is moved to a certain position, the locking screw 16 is tightened. In the fourth step, the fixing member 9 is adjusted. After the camera 12 is focused, the compression bolt 11 is tightened, and the camera 12 can clearly capture the body part of the forest pest. Of course, the camera 12 can also autofocus by itself, and the design of the telescopic member can further improve the imaging effect of the camera 12.
