Description

Technical Field

[0001] This utility model relates to the field of plant specimen preparation technology, and in particular to a folding plant specimen clip. Background Technology

[0002] A plant specimen press is a specialized tool used for pressing and drying plant specimens. It mainly consists of two identical rigid plates (usually made of wood or plastic), used in conjunction with absorbent paper, string, and other auxiliary materials. Its working principle is to apply continuous and even pressure to the plant specimen through the plates, causing the absorbent paper to absorb and rapidly evaporate the moisture in the specimen, thus preserving the plant's original shape and color for long-term storage. To use, fresh plants are flattened, sandwiched between absorbent paper, placed inside the plates, and then secured with binding. The absorbent paper needs to be replaced periodically to accelerate drying. It is widely used in botanical teaching, research collection, and specimen preparation.

[0003] Existing specimen clips have several significant drawbacks: they rely heavily on rope binding for fixation, which requires repeated wrapping and knotting during opening and closing, making the process cumbersome and inefficient. Each fixation takes a considerable amount of time, and uneven manual binding can lead to stress imbalances in the clips, causing slow dehydration at specimen edges and folds due to insufficient pressure. In humid environments, specimens may mold within 48 hours, and deformities such as leaf curling and flower rot are frequent. More importantly, changing the absorbent paper requires completely untying the ropes and opening the clips, during which specimens are prone to sliding and shifting within the absorbent paper, especially small floral and leafy specimens, whose morphology is easily damaged. Repeated operations not only further reduce efficiency but also affect the drying stability of the specimens due to frequent disturbance. Overall, they are significantly inadequate in terms of ease of operation, portability, and specimen protection.

[0004] In response to this technical problem, this application proposes a foldable plant specimen clip. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as reliance on rope binding, cumbersome and inefficient operation, uneven pressure leading to easy damage to specimens, lack of folding making it inconvenient to carry, and the need to fully open the container to change absorbent paper, which can easily lead to misalignment. The proposed invention is a foldable plant specimen clip.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A folding plant specimen clip includes a lower clip plate, an upper clip plate rotatably connected to the top rear end of the lower clip plate, mounting grooves on the inner walls of both the lower and upper clip plates, pressure plates detachably connected to the inner walls of the mounting grooves, a positioning block connected to the left inner wall of the pressure plate via an adjustment assembly, limit bolts fixedly connected to the front and rear ends of the left sides of both the lower and upper clip plates, the outer walls of the limit bolts engaging with the opposite side of the positioning blocks, and corrugated cardboard detachably connected to the inner walls of the lower and upper clip plates, with absorbent paper placed on the top of the corrugated cardboard.

[0008] Furthermore, the lower clamping plate has reserved slots on both the left and right sides of its front side, and the front end of the upper clamping plate is rotatably connected to a connecting bolt. The outer side of the connecting bolt is adapted to the inner wall of the reserved slot, and the bottom end of the connecting bolt is threaded with a knob.

[0009] Furthermore, the adjusting assembly includes a bidirectional screw, which is rotatably connected to the left inner wall of the lower clamping plate and the upper clamping plate. Positioning blocks are sleeved on the front and rear ends of the bidirectional screw, and the outer right end of the positioning block is slidably connected to the inner wall of the pressure plate. A sleeve rod is fixedly connected to the outer middle end of the bidirectional screw.

[0010] Furthermore, the top of the knob is provided with an anti-slip pad.

[0011] Furthermore, the top of the pressure plate is provided with multiple through slots.

[0012] Furthermore, a handle is fixedly connected to the front end of both the lower clamping plate and the upper clamping plate.

[0013] Furthermore, the bottom rear end of the lower clamping plate is fixedly connected to two fixed support legs, and the height of the two fixed support legs is consistent with the height of the part exposed after the connecting bolt is inserted into the inner wall of the reserved slot.

[0014] Furthermore, the shape of the positioning block at one end is a semi-circular arc, and the diameter of the middle end of the limiting bolt is adapted to the diameter of the positioning block at one end.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the folding structure, the rotating connection between the lower and upper clamping plates, the connecting bolts, the reserved slots, and the knob fixing structure completely replace the traditional rope binding method. This not only simplifies the opening, closing, and fixing operations from tedious wrapping and knotting to quick locking and rotation, greatly improving the efficiency of use, but also avoids the problem of uneven force on the specimen caused by uneven force during manual binding, ensuring uniform pressure and reducing the risk of specimen mold and deformation.

[0017] 2. In this utility model, the absorbent paper can be replaced without opening the specimen clip. By rotating the sleeve rod to drive the positioning block to disengage from the limit bolt, the pressure plate, corrugated cardboard and absorbent paper can be quickly removed. After replacement, the reverse operation can be performed to complete the installation. This eliminates the steps of repeatedly untying and re-tying when replacing absorbent paper in traditional specimen clips, greatly improving the convenience of operation. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 - Figure 3An embodiment of this utility model provides a foldable plant specimen clip, including a lower clip plate 1, an upper clip plate 2 rotatably connected to the top and rear end of the lower clip plate 1, an installation groove 3 is provided on the inner wall of both the lower clip plate 1 and the upper clip plate 2, a pressure plate 4 is detachably connected to the inner wall of the installation groove 3, a positioning block 8 is connected to the inner wall of the left end of the pressure plate 4 through an adjustment component, a limit bolt 5 is fixedly connected to the front and rear ends of the left side of both the lower clip plate 1 and the upper clip plate 2, the outer wall of the limit bolt 5 is engaged with the side of the positioning block 8 that is away from it, and a corrugated cardboard 10 is detachably connected to the inner wall of the lower clip plate 1 and the upper clip plate 2, and an absorbent paper 11 is provided on the top of the corrugated cardboard 10;

[0027] Specifically, this invention effectively overcomes the shortcomings of existing specimen clips, which mostly use ropes to connect two clip frames, resulting in inconvenience in carrying and low efficiency. It includes a lower clip 1, with an upper clip 2 rotatably connected to the top and rear end of the lower clip 1. This rotatable connection structure allows the specimen clip to be folded for storage, significantly reducing its volume during storage and carrying. This solves the problem of traditional specimen clips taking up a lot of space and being heavy to carry due to fixed connections. Both the lower clip 1 and the upper clip 2 have mounting grooves 3 on their inner walls, with pressure plates 4 detachably connected to the inner walls of the mounting grooves 3. A positioning block 8 is connected to the inner wall of the left end of the pressure plate 4 via an adjustment component. Limiting bolts 5 are fixedly connected to the front and rear ends of the left side of both the lower clip 1 and the upper clip 2. The outer wall of the limiting bolt 5 engages with the opposite side of the positioning block 8. Through the engagement of the positioning block 8 and the limiting bolt 5, the position of the pressure plate 4 is stably fixed, ensuring that the pressure plate 4 is aligned with the target. Applying stable pressure, corrugated cardboard 10 is detachably connected to the inner walls of the lower clamping plate 1 and the upper clamping plate 2. Absorbent paper 11 is placed on the top of the corrugated cardboard 10. The corrugated cardboard 10 has good air permeability and support, and can work with the absorbent paper 11 to more efficiently absorb moisture from the specimen, accelerating the drying speed. The lower clamping plate 1 has pre-reserved slots 12 on both the left and right sides of its front side. A connecting bolt 13 is rotatably connected to the front end of the upper clamping plate 2. The outer side of the connecting bolt 13 is adapted to the inner wall of the pre-reserved slot 12. A knob 14 is threaded to the bottom end of the connecting bolt 13. By inserting the connecting bolt 13 into the pre-reserved slot 12 and tightening it with the knob 14, the lower clamping plate 1 and the upper clamping plate 2 can be quickly fixed, replacing the traditional rope binding method. This method is convenient to operate and securely fixed, effectively avoiding the problem of uneven specimen force caused by uneven binding in traditional methods.

[0028] Reference Figure 3 - Figure 5The lower clamping plate 1 has pre-drilled slots 12 on both the left and right sides of its front side. A connecting bolt 13 is rotatably connected to the front end of the upper clamping plate 2. The outer side of the connecting bolt 13 is adapted to the inner wall of the pre-drilled slot 12. A knob 14 is threadedly connected to the bottom end of the connecting bolt 13. The adjusting assembly includes a bidirectional screw 6, which is rotatably connected to the inner wall of the left end of the lower clamping plate 1 and the upper clamping plate 2. Positioning blocks 8 are fitted onto the front and rear ends of the bidirectional screw 6. The outer right end of the positioning block 8 is slidably connected to the inner wall of the pressure plate 4. A sleeve rod 7 is fixedly connected to the middle of the outer side; an anti-slip pad is provided on the top of the knob 14; multiple through slots 9 are opened on the top of the pressure plate 4; handles 15 are fixedly connected to the front ends of both the lower clamping plate 1 and the upper clamping plate 2; two fixed support legs 16 are fixedly connected to the rear end of the bottom of the lower clamping plate 1, and the height of the two fixed support legs 16 is consistent with the height of the part exposed after the connecting bolt 13 is inserted into the inner wall of the reserved slot 12; the shape of the positioning block 8 at one end is semi-circular, and the diameter of the middle end of the limiting bolt 5 is adapted to the diameter of the positioning block 8 at one end.

[0029] Specifically, the adjustment assembly includes a bidirectional screw 6, which is rotatably connected to the inner left wall of the lower clamping plate 1 and the upper clamping plate 2. Positioning blocks 8 are fitted onto the front and rear ends of the bidirectional screw 6. The outer right end of the positioning block 8 is slidably connected to the inner wall of the pressure plate 4. A sleeve rod 7 is fixedly connected to the middle outer end of the bidirectional screw 6. Rotating the sleeve rod 7 drives the bidirectional screw 6 to rotate, thereby causing the positioning block 8 to slide relative to the bidirectional screw 6, achieving engagement or disengagement between the positioning block 8 and the limit bolt 5. The operation is simple and efficient. An anti-slip pad is provided on the top of the knob 14, increasing friction when rotating the knob 14, facilitating tightening and preventing slippage. Multiple through slots 9 are provided on the top of the pressure plate 4, enhancing airflow. The evaporation of moisture from the specimen and absorbent paper 11 is accelerated, improving drying efficiency. Handles 15 are fixedly connected to the front ends of both the lower clamping plate 1 and the upper clamping plate 2, making it convenient for users to carry the specimen clip and further enhancing its portability. Two fixed support legs 16 are fixedly connected to the rear end of the lower clamping plate 1. The height of the two support legs 16 is consistent with the height of the exposed portion after the connecting bolt 13 is inserted into the inner wall of the reserved slot 12, ensuring the specimen clip remains stable when placed and preventing damage to the specimen due to unstable placement. The shape of the positioning block 8 at one end is semi-circular, and the diameter of the middle end of the limiting bolt 5 matches the diameter of the positioning block 8 at one end, ensuring the tightness and stability of the engagement between the positioning block 8 and the limiting bolt 5.

[0030] Working principle: In use, first slide the pressure plate 4 into the mounting groove 3 and rotate the sleeve rod 7 to drive the double-ended screw 6 to rotate, causing the positioning block 8 to slide relative to each other and engage with the limiting bolt 5, thereby fixing the pressure plate 4. Place the plant specimen on the absorbent paper 11, and then place the absorbent paper 11 and corrugated cardboard 10 between the lower clamping plate 1 and the upper clamping plate 2. The pressure plate 4 applies uniform pressure to the specimen, and the through groove 9 promotes air circulation and accelerates moisture evaporation. When it is necessary to replace the absorbent paper 11, there is no need to open the specimen clamp. Simply rotate the double-ended screw 6 to drive the positioning block 8 to slide relative to each other and disengage from the limiting bolt 5, and the pressure plate 4 can be removed. Then, snap the clamp back on. Remove the corrugated cardboard 10 and take out the absorbent paper 11 for replacement. After replacement, reverse the operation to install the pressure plate 4. This greatly improves the efficiency of replacing absorbent paper and avoids the tedious operation of repeatedly untying and binding ropes when replacing absorbent paper in traditional specimen clips. When folding and storing, first rotate the lower clip 1 and the upper clip 2 to fit together, then rotate the connecting bolt 13 to insert it into the reserved slot 12, and then rotate the knob 14 to tighten it. This completes the fixed connection between the lower clip 1 and the upper clip 2. The folded specimen clip is compact and easy to carry with the handle 15, solving the problem of inconvenience in carrying traditional specimen clips.
