Description

Technical Field

[0001] The utility model relates to the technical field of specimen preservation, in particular to a plant specimen preservation device. Background Art

[0002] A plant specimen is a material carrier that is collected, processed and preserved to study, identify and display plants. It preserves the shape and color of the plant for future observation and research. When collecting and preserving plant specimens, specimen clamps are an important tool for pressing and preserving plant specimens.

[0003] According to the "Plant Specimen Collection Clamp" disclosed in Chinese Patent Publication No. CN220023989U, the device includes several stacked plates, each of which has a placement slot on its upper surface. Except for the bottom plate, the bottom surfaces of all other plates have a receiving slot. Each receiving slot is provided with a squeeze plate, and the squeeze plate is adapted to fit within the placement slot. By inserting the upper squeeze plate into the lower placement slot, the thickness of the plant pushes the squeeze plate upward within the receiving slot, simultaneously driving the elastic component to contract. Subsequently, the two plates are fixed by the surrounding clamping components. The squeeze plate constantly squeezes and clamps the plant under the elastic force of the elastic component. By stacking multiple plates, multiple plant specimens can be collected. By installing two adjacent plates, the plants can be clamped and fixed, greatly reducing the stacking thickness of the collection clamp and facilitating portability. At the same time, the squeeze plate on the bottom of the plate can continuously apply pressure to the plant, improving the specimen shaping effect.

[0004] However, during the pressing process of plant specimens, dry absorbent paper needs to be replaced regularly to ensure that the plant specimens can be evenly dried. In the above-mentioned device, different plant specimens are pressed and stacked together through a plate. When a certain type of plant specimen needs to be replaced, the entire specimen clamp needs to be disassembled, which is very inconvenient and makes the device have certain limitations. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a plant specimen preservation device. When the absorbent paper in a certain plate body needs to be replaced, there is no need to disassemble the entire plate body. The pressing plate at the plate body only needs to be raised again by the handle to release the fixation. Then the placement plate and the pressing plate can be pulled out of the inner side of the plate body. The staff can then replace the absorbent paper and then put it back in, thereby achieving the effect of facilitating the replacement of the absorbent paper.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A plant specimen preservation device comprises a plate body, a preservation mechanism is provided on the outside of the plate body, and a connecting mechanism is provided on the outside of the plate body;

[0008] The storage mechanism includes a placement plate and a pressing plate. The left and right sides of the placement plate are fixedly connected with sliding blocks. The outside of the pressing plate is provided with a pressing assembly. The front of the sliding block is provided with a positioning plate. The front of the positioning plate is installed with an extrusion block.

[0009] Preferably, the pressing assembly includes a pressing groove, the internal rotation of the pressing groove is connected to a screw rod, the external thread of the screw rod is connected to a connecting block, the outside of the screw rod is installed with a first transmission wheel, the external transmission of the first transmission wheel is connected to a transmission belt, and the inside of the transmission belt is installed with a second transmission wheel.

[0010] Preferably, the exterior of the connecting block is engaged with one end of the pressing plate, and a handle is installed on the top of the second transmission wheel.

[0011] Preferably, one end of the sliding block is slidably connected to the inner side of the plate body, a protrusion is provided at one end of the sliding block, the back side of the positioning plate is clamped with the front side of the plate body, a damping shaft is installed at one end of the extrusion block, and one end of the damping shaft is rotatably connected to the front side of the plate body.

[0012] Preferably, the connecting mechanism includes a rotating shaft and a connecting groove, the outside of the rotating shaft is fixedly connected to a fixed plate, one end of the fixed plate is fixedly connected to a fixed column, the inner side of the connecting groove is fixedly connected to a return spring, the top of the return spring is fixedly connected to a limiting block, and one end of the limiting block is fixedly connected to a lifting rod.

[0013] Preferably, the rotating shaft is rotatably connected to the outside of the plate body, and the connecting grooves are opened on the left and right sides of the plate body.

[0014] Preferably, the limiting block is configured to be T-shaped, and the bottom of the limiting block is configured to be an oblique triangle.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] First, by installing absorbent paper on the top of the placement plate and the bottom of the pressing plate, and then slidingly connecting the sliding blocks on the left and right sides of the placement plate with the inner side of the plate body, the placement plate can be pushed into the inner side of the plate body, and the protrusions on the back of the sliding blocks are engaged with the inner side of the plate body, thereby fixing the placement plate, and then pushing the pressing plate into the inner side of the plate body, and making the protruding ends on the left and right sides of the pressing plate engage with the connecting blocks, and then, according to the type of plant specimen, the second transmission wheel is driven to rotate by the handle outside the second transmission wheel, and then the transmission belt is driven to rotate, so that the first transmission wheel rotates, and the first transmission wheel drives The screw rotates, causing the connecting block to move downward, thereby driving the pressing plate to descend, so that the pressing plate is pressed on the plant specimen to perform a pressing operation, and the pressing force can be adjusted. Then, multiple plates can be connected through the connecting mechanism, and multiple plates can be stacked to collect multiple plant specimens. When the absorbent paper in a certain plate needs to be replaced, there is no need to disassemble the entire plate. Only the pressing plate at the plate can be raised again by the handle to release the fixation. Then, the placement plate and the pressing plate can be pulled out of the inner side of the plate body, and the staff can replace the absorbent paper and then put it back in, so as to achieve the effect of facilitating the replacement of the absorbent paper.

[0017] Secondly, by placing one plate body on the other plate body, and then using the set rotating shaft to allow the fixed plate to rotate, the fixed column can slide in the connecting groove until the fixed column enters the connecting groove of the other plate body. Since the bottom of the limit block is set to be triangular, the fixed column can push the limit block to rise. After the fixed column passes through the limit block, the limit block is reset under the action of the reset spring, and then the fixed column is limited and fixed to prevent the fixed column from returning, thereby connecting the two plate bodies. When the two plate bodies need to be disassembled, only the limit block needs to be lowered by pulling the lifting rod, and the fixed column can be retracted to release the fixation between the two plate bodies, thereby achieving the effect of facilitating connection and disassembly.
