Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, and in particular relates to a plant tissue slicing device. Background Technology

[0002] In botanical research, the microstructure analysis of plant tissues is fundamental to understanding key processes such as plant growth, development, physiological functions, and responses to environmental changes. The traditional process of preparing plant tissue sections usually involves multiple tedious steps, such as sample collection, fixation, dehydration, infiltration, embedding, sectioning, staining, and mounting. Each step directly affects the quality of the final section and the observation results.

[0003] While existing plant tissue sectioning devices have indeed made significant progress in mechanized operation and effectively improved sectioning efficiency, these devices still have some obvious shortcomings in their design, especially the way the sample is fixed on the sample holder and the installation method of the receiving box, which poses considerable safety hazards to the experimenters.

[0004] First, because the sample holder is fixed in position and the slicing blade is installed at the upper end of the sample holder, the experimenter's hands are likely to come into contact with the slicing blade when installing the sample, which undoubtedly increases the risk of being cut. Second, there is also a risk of being cut by the slicing blade when installing the receiving box. Since the receiving box is usually placed below the slicing blade to collect the slices, and the receiving box also needs to be connected to the sample holder, the experimenter can easily touch the sharp edge of the slicing blade when installing and removing the receiving box. If the operation is not careful, it will also cause a cut. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a plant tissue slicing device.

[0006] To achieve the above objectives, the utility model employs the following technical solution: a plant tissue slicing device, comprising a slicer body and an installation groove formed on the slicer body, a sample placement seat provided on the inner side of the installation groove, a receiving box provided on the sample placement seat, a moving component provided between the sample placement seat and the installation groove, the moving component including a motor mounted on the slicer body, a threaded rod installed on the output end of the motor, and a threaded sleeve connected to the sample placement seat fitted on the outer side of the threaded rod; a locking element is provided between the sample placement seat and the receiving box.

[0007] By adopting the above technical solution and introducing moving components, locking elements, and a series of detailed designs, the flexibility, safety, and convenience of slicing operations have been significantly improved. This device not only reduces the operational difficulty and labor intensity for experimental personnel, but also improves the quality of slices and the accuracy of experiments, providing stronger support for botanical research and experiments.

[0008] Optionally, the bottom wall of the mounting groove is provided with a fixing groove, and the end of the threaded rod away from the motor is connected to the inner side wall of the fixing groove through a bearing.

[0009] By adopting the above technical solution, the fixing groove opened on the bottom wall of the mounting groove is connected to one end of the threaded rod through the bearing, which ensures the stability of the threaded rod during rotation, thereby ensuring the smooth movement of the sample placement seat.

[0010] Optionally, the side wall of the sample placement seat is equipped with two pairs of slides, which are symmetrically distributed, and the side wall of the mounting groove is provided with a sliding groove for the two pairs of slides to slide.

[0011] By adopting the above technical solution, the two pairs of sliding blocks installed on the side wall of the sample placement seat cooperate with the sliding grooves on the side wall of the mounting groove, which further enhances the stability and accuracy of the sample placement seat movement and improves the precision of the slice.

[0012] Optionally, a pair of connecting posts are installed on the outer wall of the threaded sleeve. The cross-section of the pair of connecting posts is "T" shaped, and a plurality of fixing holes are opened at the end of the pair of connecting posts away from the threaded sleeve.

[0013] By adopting the above technical solution, the "T"-shaped connecting post and fixing hole installed on the outer wall of the threaded sleeve increases the stability and strength of the connection, while facilitating connection with external fixing devices and further enhancing the stability of the sample placement seat.

[0014] Optionally, the locking element includes a pair of mating grooves formed on the sample placement seat, with locking pins connected to the side walls of the pair of mating grooves respectively, and a return spring installed between the locking pins and the sample placement seat. An insertion seat is installed on one end of the receiving box near the pair of mating grooves, and a locking hole is formed on the side wall of the insertion seat.

[0015] By adopting the above technical solution and the design of the locking component, the receiving box and the sample placement seat are firmly fixed, preventing them from falling off or shifting during the slicing process, simplifying the operation process and improving experimental efficiency.

[0016] Optionally, the sidewalls of the pair of docking slots are respectively provided with through holes for mounting the locking post. When the receiving box is in contact with the sample placement seat, the through holes align with the locking holes.

[0017] By adopting the above technical solution, the perforation opened on the side wall of the docking groove is aligned with the locking hole on the side wall of the insertion seat, ensuring that the locking pin can be smoothly inserted into the locking hole, thus achieving rapid fixation of the receiving box.

[0018] Optionally, the slicer body has a cavity for mounting the motor, and a cover plate is installed on the side wall of the cavity.

[0019] By adopting the above technical solution, the motor mounting cavity and cover plate opened on the slicer body not only save space, but also ensure the safe and stable operation of the motor.

The sample placement seat is no longer limited to a fixed position, but can be smoothly moved along the mounting groove by a motor according to the needs of the experimenter, until the end of the sample placement seat is located outside the microtome body. This design not only improves the flexibility and diversity of slicing, but also allows the experimenter to install and adjust the sample from a safe position away from the microtome blade, thereby greatly reducing the risk of being scratched.

[0022] 2. The locking mechanism design makes the installation and removal of the receiving box simpler and more convenient. At the same time, the connection between the receiving box and the sample placement seat allows the receiving box to be installed on the outside of the slicer body and then moved to the inside of the slicer body. This design allows the experimenter to operate in a safe area away from the slicer blade, thereby effectively avoiding scratch accidents. Attached Figure Description

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] like Figure 1 As shown in Figure 4, the specific scheme of the embodiment is as follows: A plant tissue slicing device includes a slicer body 1. The slicer body 1 serves as the basic support structure of the entire device. The slicer body 1 provides a stable working environment, ensuring the accuracy and safety of the slicing operation. Its design is reasonable and its structure is robust, capable of withstanding various forces and vibrations during the slicing process. At the same time, the slicer body 1 is also equipped with a control device and an installation groove 2 opened on the slicer body 1. The installation groove 2 is opened on the slicer body 1, providing installation space for the sample placement seat 3 and the slicing blade. The bottom wall of the installation groove 2 is provided with a fixing groove 202. The fixing groove 202 is located on the bottom wall of the installation groove 2 and is connected by a bearing. The fixing groove 202 ensures the stability of the threaded rod 7 during the rotation process, thereby ensuring the smooth movement of the sample placement seat 3.

[0031] The inner side of the mounting groove 2 is provided with a sample placement seat 3, which is used to place the plant tissue sample to be sliced. It can firmly fix the sample and prevent displacement or falling off during the slicing process. At the same time, the sample placement seat 3 is provided with a sample placement channel 10 for placing the sample. The other end of the sample placement channel is connected to the placement groove. The inner side of the placement groove is equipped with a pusher for pushing the sample. The pusher is not shown in the figure, but it is the same as the components in the existing equipment. Two pairs of slides 301 are installed on the side wall of the sample placement seat 3. The two pairs of slides 301 are symmetrically distributed. The side wall of the mounting groove 2 has a sliding groove 201 for the two pairs of slides 301 to slide. The slides 301 are installed on the side wall of the sample placement seat 3 and cooperate with the sliding groove 201 on the side wall of the mounting groove 2 to realize the smooth movement of the sample placement seat 3. This design not only improves the accuracy of slicing, but also makes the operation more convenient and flexible.

[0032] The sample placement seat 3 is provided with a receiving box 4, and a moving component 5 is provided between the sample placement seat 3 and the mounting groove 2. The design of the moving component 5 realizes the automated movement of the sample placement seat 3, improves the slicing efficiency, and reduces the labor intensity of the experimental personnel.

[0033] The moving component 5 includes a motor 6 mounted on the slicer body 1. The slicer body 1 has a cavity 101 for mounting the motor 6. A cover plate is installed on the side wall of the cavity 101. The motor 6 is installed in the cavity 101 on the slicer body 1 and is sealed and protected by the cover plate. This design not only saves space but also ensures the safe and stable operation of the motor 6. The driving force of the motor 6 is transmitted to the sample placement seat 3 through the threaded rod 7, realizing the movement of the sample.

[0034] A threaded rod 7 is installed at the output end of the motor 6. The end of the threaded rod 7 away from the motor 6 is connected to the inner wall of the fixing groove 202 through a bearing. A threaded sleeve 8 connected to the sample placement seat 3 is sleeved on the outer side of the threaded rod 7. The threaded rod 7 is fixed in the fixing groove 202 through the bearing. The threaded sleeve 8 is sleeved on the outer side of the threaded rod 7 and connected to the sample placement seat 3. When the motor 6 drives the threaded rod 7 to rotate, the threaded sleeve 8 drives the sample placement seat 3 to move along the mounting groove 2. This design realizes the smooth and precise movement of the sample placement seat 3. A pair of connecting posts 801 are installed on the outer wall of the threaded sleeve 8. The cross-section of the pair of connecting posts 801 is "T". Several fixing holes 802 are opened at the end of the pair of connecting posts 801 away from the threaded sleeve 8. The connecting posts 801 are installed on the outer wall of the threaded sleeve 8. Their cross-section is "T", which increases the stability and strength of the connection. The fixing holes 802 are opened at the far end of the connecting posts 801 for connection with external fixing devices, which further enhances the stability of the sample placement seat 3.

[0035] A locking element 9 is provided between the sample placement seat 3 and the receiving box 4. The locking element 9 includes a pair of mating grooves 91 formed on the sample placement seat 3. The side walls of the pair of mating grooves 91 are respectively provided with through holes for the installation of locking pins 92. When the receiving box 4 is in contact with the sample placement seat 3, the through holes are aligned with the locking holes 95. The side walls of the pair of mating grooves 91 are respectively connected to locking pins 92. The side walls of the sample placement seat 3 are provided with grooves. When the locking pins 92 are locked with the locking holes 95, the end of the locking pins 92 located outside the mating grooves 91 is on the same horizontal plane as the groove. This design can prevent the locking pins 92 from obstructing the movement of the sample placement seat 3 during movement. A return spring 93 is installed between the locking pins 92 and the sample placement seat 3. An insertion seat 94 is installed on the end of the receiving box 4 near the pair of mating grooves 91. The side wall of the insertion seat 94 is provided with locking holes 95.

[0036] The locking element 9 securely fixes the receiving box 4 to the sample holder 3, preventing it from falling off or shifting during slicing. Simultaneously, the convenient operation of the locking element 9 improves experimental efficiency. When the receiving box 4 is in contact with the sample holder 3, the perforation aligns with the locking hole 95, and the locking pin 92, under the action of the return spring 93, inserts into the locking hole 95, thus fixing the receiving box 4 in place. The insertion seat 94 facilitates quick and accurate installation and removal of the receiving box 4 by the experimenter.

[0037] The slicer body 1 in this application is the same as the body of the BS-1018 vibrating slicer, and both have the same control device and the same operating principle. The difference is that the sample placement seat 3 on the slicer body 1 in this application is telescopic, while the sample placement seat 3 on the BS-1018 vibrating slicer is fixed. In addition, the connection method of the receiving box 4 of the two is different.

[0038] The working principle of the above embodiments is as follows:

[0039] When researchers need to perform tissue sectioning on plants, they first start motor 6 via the control device on the microtome body 1. Upon receiving the start signal, motor 6's output drives the threaded rod 7 to rotate. Since the threaded rod 7 is securely mounted in the fixed groove 202 via bearings, and the threaded sleeve 8 is tightly fitted onto the outside of the threaded rod 7 and connected to the sample placement seat 3, when the threaded rod 7 rotates, the threaded sleeve 8 moves along the threaded rod 7 under the action of the threads, thereby causing the sample placement seat 3 to move smoothly within the mounting groove 2. This process continues until the sample placement end of the sample placement seat 3 moves to the outside of the mounting groove 2, that is, below the microtome blade, preparing for the sectioning operation.

[0040] Next, the experimenters will install the pre-prepared plant tissue sample on the sample placement seat 3. During this process, the experimenters need to ensure that the sample is firmly fixed on the sample placement seat 3 to prevent displacement or detachment during the sectioning process, which would affect the accuracy and effect of the sectioning.

[0041] Then, the experimenters will align the receiving box 4 with the sample placement seat 3. Specifically, they will place the end of the receiving box 4 closest to the sample placement seat 3 against the sample placement seat 3, aligning the insertion seat 94 on the receiving box 4 with the docking groove 91 on the sample placement seat 3. At this time, since the side wall of the docking groove 91 has a through hole for installing the locking post 92, and the through hole corresponds to the position of the locking hole 95 on the receiving box 4, the locking post 92 will automatically insert into the locking hole 95 under the action of the return spring 93, firmly fixing the receiving box 4 to the sample placement seat 3. This locking method is not only simple and convenient, but also ensures that the receiving box 4 will not fall off or shift during the slicing process, thus ensuring the smooth progress of the slicing operation.

[0042] At this point, the experimenters have completed all the preparations before slicing. By using the control device on the slicer body 1 to reset the sample placement seat 3, the experimenters only need to control the slicer blade through the control device to perform the slicing operation. During the slicing process, the experimenters need to pay close attention to the slicing situation and adjust parameters such as the position of the sample placement seat 3 and the speed of the slicer blade as needed to ensure that high-quality sliced ​​samples are obtained.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
