Description

A pressure-adjustable specimen holder

technical field

The utility model relates to a specimen holder.

Background technique

Specimen clip is a common preservation tool for collecting plant specimens in the field. Using the water absorption capacity of absorbent paper and the pressing force of the specimen clip, the specimen can be quickly dried and flattened. If the force is uneven, the specimen will be insufficiently dried or uneven. . However, in the prior art, in order to flatten the specimen and quickly dry it, it is necessary to use multiple operations such as binding to make the specimen in close contact with the absorbent paper. When replacing the absorbent paper or adjusting the specimen, it is necessary to open and repeat the operations such as binding again, which is extremely cumbersome. , and the pressure is not easy to grasp and adjust, and it is difficult to achieve uniform force.

Utility model content

The utility model provides a pressure-adjustable specimen holder to solve the problems of extremely cumbersome operations and difficult control and adjustment of the pressure when replacing the absorbent paper or adjusting the specimen in the prior art.

A pressure-adjustable specimen holder, which comprises a shell, an elastic component and a splint;

The shell is composed of an upper shell plate, a lower shell plate and a side shell plate; the upper shell plate and the lower shell plate are arranged in parallel, and one side end of the upper shell plate and the lower shell plate are respectively connected with the upper and lower shell plates of the side shell plate. The two ends are hinged, and the other side ends of the upper shell plate and the lower shell plate are fixed by means of buckles and protrusions, respectively; the upper shell plate and the lower shell plate are provided with a plurality of adjustment holes;

And between the upper shell plate and the lower shell plate, a plurality of plywood are arranged in parallel from top to bottom, and one end of the plywood is softly connected to the side shell plate;

Elastic components are respectively arranged between the upper shell plate and the clamping plate and between the lower shell plate and the clamping plate;

The elastic component is composed of a plurality of arc-shaped elastic sheets and a plurality of adjustment components. One side of the arc-shaped elastic sheets arranged at both ends between the upper shell plate and the plywood is fixed on the upper shell plate, and the lower shell plate and the plywood are fixed on the upper shell plate. One side of the arc-shaped elastic sheets arranged at both ends is fixed on the lower shell plate; a plurality of adjustment components are arranged between the adjacent arc-shaped elastic sheets; the adjustment components are composed of left-hand screw, right-hand screw and thread A sleeve is formed, and one end of the left-handed screw and the right-handed screw are respectively fixedly connected with one side of the arc-shaped elastic sheet, and the other ends of the left-handed screw and the right-handed screw are respectively threadedly connected with both sides of the threaded sleeve; the threaded sleeve They are respectively arranged in the adjustment holes on the upper shell plate and the lower shell plate.

The working principle of the present utility model:

The collected plants are placed between the adjacent splints, and then fixed by snaps and protrusions. Since the threaded sleeves are respectively set in the square holes on the upper shell plate and the lower shell plate, when the specimen clips are closed, the The threaded sleeve can be adjusted. The threaded sleeve can make the left-handed screw and the right-handed screw rotate outward or inward at the same time, thereby changing the shape of the arc-shaped elastic sheet. When screwing inward, the arc-shaped elastic sheet The distance between the two ends becomes smaller, and the splint and the side shell plate are softly connected. The elastic component squeezes multiple splints from the upper and lower sides at the same time and increases the extrusion force. When it is rotated out, the distance between the two ends of the arc-shaped elastic sheet changes. If the pressing force is large, the pressing force is reduced. Therefore, the utility model can adjust the pressing force of the pressing according to the needs, and the adjustment is simple and the operation is easy.

After the threaded sleeve is adjusted, the shape of the curved elastic sheet remains constant and will not change. Therefore, when replacing the absorbent paper or adjusting the specimen, it is only necessary to open the buckle. After replacement or adjustment, only the buckle needs to be opened. It can be fixed again. The constant shape of the curved elastic sheet directly exerts pressure on the splint without other operations, which is convenient and easy to operate.

The elastic component is composed of a plurality of arc-shaped elastic sheets and a plurality of adjustment components. According to different positions, different pressures can be adjusted according to actual needs.

The beneficial effects of the present utility model are:

1. The pressing force of the extrusion can be adjusted according to the needs, and the adjustment is simple and easy to operate;

2. According to different positions, different pressures can be adjusted according to actual needs;

3. When replacing the absorbent paper or adjusting the specimen, you only need to open the clip. After replacement or adjustment, you only need to re-fix the clip without other operations, which is convenient and easy to operate.
