Description

Technical Field

[0001] This utility model relates to the field of inoculation, and more specifically, to a sterile inoculation device for plants. Background Technology

[0002] In the early stages of plant tissue culture, plant seeds or seedlings are inoculated. The inoculation process needs to be carried out in a sterile environment, thus requiring the use of sterile inoculation equipment. During sterile inoculation, the operation is primarily performed by the operator's hands, and a high degree of precision is required, such as accurately placing the seed into the designated position on the culture medium.

[0003] During aseptic inoculation, if the volume is large, the inoculation bottles and sterilizers are at a certain height relative to the workbench, requiring the operator's hands to remain suspended in the air. Over time, this leads to hand fatigue, which is difficult to alleviate by immediately resting the elbows on the platform. This fatigue can cause errors or even inoculation failures. Therefore, this design proposes a plant aseptic inoculation device that effectively reduces hand fatigue during operation. Utility Model Content

[0004] The technical problem to be solved by this invention is the fatigue of the hands of staff during aseptic inoculation operations.

[0005] To address the problems in the prior art, this utility model proposes a sterile inoculation device for plants, comprising a device body, an open working space formed on the upper part of the device body and a workbench located within the working space, and a support mechanism for supporting an arm is provided near the edge of the workbench.

[0006] Furthermore, the support mechanism includes a support platform, and a connecting rod is movably connected below the support platform.

[0007] Furthermore, a sliding component is connected to the lower end of the connecting rod, and a guide mechanism is slidably connected to the other end of the sliding component.

[0008] Furthermore, an active space is formed in the lower part of the device body, and the guide mechanism includes a horizontal plate connected to the two side walls of the active space. A sliding rod is provided on the upper side of the horizontal plate, and the sliding component is sleeved on the surface of the sliding rod through a through hole.

[0009] Furthermore, the sliding component is also integrally connected to a stabilizing part, the end face of which is located on one side of the horizontal plate abuts against the outer surface of the horizontal plate.

[0010] Furthermore, the support platform bends upward to form a support groove.

[0011] Furthermore, the lower end of the connecting rod is hinged to the sliding component; grooves are provided at the connection points between the two side walls of the active space and the horizontal plate.

[0012] Furthermore, the connecting rod includes a connecting rod 1 with one end hollow and a connecting rod 2. The connecting rod 1 is connected to the connecting rod 2 through a telescopic component. The upper end of the connecting rod 1 is connected to the support platform, and the lower end of the connecting rod 2 is connected to the sliding component.

[0013] Furthermore, the telescopic component is a threaded connecting rod, and the hollow side of the connecting rod and the connecting rod are provided with internal threads. The connecting rod is connected to the connecting rod 2 through the threaded connecting rod.

[0014] Furthermore, a locking device is installed on the sliding component. The locking device includes a locking block disposed within the sliding component, and the locking block is connected to a locking switch, which is located outside the sliding component.

[0015] The aseptic inoculation device for plants of this utility model has the following beneficial effects:

[0016] First, a support mechanism is installed near the workbench. When staff feel arm fatigue during operation, they can place their arms directly on the support platform of the support mechanism to reduce hand fatigue and make it easier for them to continue their work, thereby improving the accuracy of their operation during the vaccination process.

[0017] Secondly, the connecting rod is configured as two sections, connecting rod one and connecting rod two, connected by a telescopic component, thereby allowing adjustment of the height of the support platform on the support mechanism; simultaneously, the support mechanism slides back and forth on the sliding rod via a sliding component, facilitating adjustment of the relative distance between a pair of support mechanisms. Therefore, the aseptic inoculation device of this invention can be adapted to workers of different heights and shoulder widths.

[0018] Furthermore, the hinge between the connecting rod and the sliding component allows the support platform and connecting rod to rotate downwards around the hinge and be stored away from the human body via the horizontal plate along the slide groove, thus enhancing the convenience of the device.

[0026] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figure 1-5 The present invention provides a more detailed description of a sterile inoculation device for plants.

[0027] Figure 1 The illustration shows a first embodiment of a sterile inoculation device for plants according to this invention. It includes a device body 1, with a single-sided open working space 12 at the top and an inverted U-shaped movable space 14 at the bottom, allowing the worker to place their feet within the movable space 14 when seated. The bottom surface of the working space 12 is a workbench 13, on which instruments and devices necessary for sterilization during the inoculation process, such as high-temperature sterilizers for scissors and tweezers, and disinfectants for culture media or seeds, can be placed. An isolation plate 11 is provided near the edge of the opening in the working space 12. The upper end of the isolation plate 11 slides into the upper side wall of the working space 12, and the isolation plate 11 can slide up and down along this side wall. A force-bearing protrusion 101 extends outward from the lower end of the isolation plate 11. By applying downward pressure or upward thrust to the force-bearing protrusion 101, the size of the opening of the working space 12 can be controlled. The isolation plate 11 is made of a transparent material, such as tempered glass.

[0028] A support mechanism 2 is installed outside the workspace 12. This support mechanism 2 supports the worker's arm to reduce hand fatigue during aseptic inoculation, improve operational precision, and thus increase the success rate of aseptic inoculation. A pair of support mechanisms 2 can be provided. Each support mechanism 2 includes a support platform 21, which is curved upwards to form a support groove 201. This groove facilitates the placement of the arm into the support platform 201, increasing the contact area between the arm and the support platform 21 and preventing the arm from slipping out during operation. A connecting rod 22 is movably connected below the support platform 21. A sliding component 23 is integrally connected to the other end of the connecting rod 22, and a guide mechanism is slidably connected to the other end of the sliding component 23. The sliding component 23 slides back and forth along the guide mechanism, adjusting the relative distance between the pair of support mechanisms 2 to accommodate workers with different shoulder widths. When using it, the staff can adjust the distance between the pair of support mechanisms 2 according to the distance between their hands and their operating habits. After completing other necessary preparations for aseptic inoculation, the staff can start the operation. The staff can place their arms on the support platform 21 at the beginning, or they can place their arms on the support platform 21 when their hands feel tired.

[0029] The guiding mechanism includes a horizontal plate 3 connected to both sides of the lower movable space 14 of the device body 1. A sliding rod 31 is provided on the upper end face of the horizontal plate 3. The support mechanism 2 is connected to the sliding rod 31 on the horizontal plate 3 through a sliding component 23. A through hole is provided at the connection end of the sliding component 23 and the sliding rod 31. The sliding component 23 is sleeved on the sliding rod 31 through the through hole, so that the support mechanism 2 can adjust the relative distance between a pair of support mechanisms 2 by sliding the sliding component 23 back and forth along the sliding rod 31. In addition, a stabilizing part 232 is formed by extending downward from the lower side of the sliding component 23. The cross-section of the stabilizing part 232 can be rectangular or triangular. The end face of the stabilizing part 232 on one side of the horizontal plate 3 is lower than the outer surface of the horizontal plate 3 to prevent the sliding component 23 from breaking or undergoing plastic deformation when the worker's arm applies downward pressure through the support platform 21.

[0030] After adjusting the distance between the pair of support mechanisms 2, to prevent the sliding component 23 from sliding along the sliding rod 31 during use and pulling the operator's arm away from the original operating position, thus causing accidental operation, a locking device can be installed on the sliding component 23. The locking device includes a locking block (not shown in the figure) disposed inside the sliding component 23, and a locking switch 231 connected to the locking block. When it is necessary to fix the support mechanism 2, the locking switch 231 can be operated to make the locking block inside the sliding component 23 abut against the surface of the horizontal plate 3 or the sliding rod 31, thereby fixing the sliding component 23 in the adjusted position.

[0031] like Figure 2As shown, in order to allow the user to move the support platform 21 to a certain angle when the arm is placed on the support platform 21, the support platform 21 and the connecting rod 22 are movably connected by a movable part 202. The movable part 202 can be a rectangular elastic silicone. One end of the elastic silicone is fixedly connected to the lower end face of the support platform 21, and the other end is connected to the upper end of the connecting rod 22. When the arm rotates horizontally or vertically at a certain angle, the elastic silicone deforms, so that the support platform 21 can move to a certain angle with the arm. The movable component 202 can also be a connecting ball made of hard stainless steel or hard plastic. The spherical surface of the connecting ball is fixedly connected to the support platform 21. The radially opposite surface of the spherical surface of the connecting ball and the support platform 21 is embedded from the upper end face of the connecting rod 22 into 1 / 2 to 2 / 3 (excluding 1 / 2) of the volume of the connecting ball, so that a contact surface is formed after the connecting ball is embedded in the connecting rod 22. The connecting ball can rotate around its center in any direction along the contact surface between the connecting ball and the connecting rod 22 without easily slipping out. Thus, under the rotation of the connecting ball, the support platform 21 can rotate 360° in the horizontal direction under the action of the arm. Depending on the size of the connecting ball and its height exposed between the support platform 21 and the connecting rod 22, the support platform 21 can be adjusted at a certain angle in the vertical direction. The movable component 202 can also be other connecting parts, as long as they can realize the function of changing the angle of the support platform 21. In this embodiment, the movable component 202 is preferably a stainless steel connecting ball.

[0032] Figure 3 The illustration shows an improvement on the first embodiment, namely, the second embodiment of this utility model. The difference from the first embodiment is that the connecting rod 22 is split into two sections: connecting rod one 221 and connecting rod two 222. Connecting rod one 221 is connected to connecting rod two 222 via a telescopic component 203. The telescopic component 203 can be a threaded connecting rod or a telescopic connecting rod; in this embodiment, the telescopic component 203 is preferably a threaded connecting rod, with external threads on its outer wall. One end of both connecting rod one 221 and connecting rod two 222 is a hollow connecting portion, with internal threads on the hollow side. Connecting rod one 221 is connected to connecting rod two 222 via the threaded connecting rod. The upper end of connecting rod one 221 is connected to the support platform 21, and the lower end of connecting rod two 222 is connected to the sliding component 23. Furthermore, the remaining structure of this embodiment is the same as the first embodiment and will not be described again here. In this embodiment, by adjusting the insertion depth of the threaded connecting rod with connecting rod one 221 or connecting rod two 222, the relative height between the support platform 21 and the workbench 13 can be adjusted, thereby making the support mechanism 2 of this utility model suitable for workers of different heights.

[0033] Figure 4 and Figure 5The third embodiment of this utility model is shown. Unlike the second embodiment, the lower end of the connecting rod 22 is tightly hinged to the sliding component 23 (the rest of the structure is the same as the second embodiment). This allows the connecting rod 22 to drive the support platform 21 to rotate downwards around the hinge point and stop at any position, allowing it to be stored away when not in use. Furthermore, a groove 32 is provided at the connection between the horizontal plate 3 and the lower side walls of the device body 1. The horizontal plate 3 can slide back and forth along the groove 32. After storing the support mechanism 2, the horizontal plate 3 is pushed inwards towards a position away from the worker, thereby causing the support mechanism 2 to be concealed within the movable space 14 below the workbench 13. Therefore, after the worker no longer needs to use or has finished using the support mechanism 2, it can be stored and concealed within the movable space 14, thus improving the convenience of the inoculation device of this utility model.

[0034] In the above embodiments, the connection method between the lower end of the connecting rod 22 and the sliding component 23 in the third embodiment is also applicable to the first embodiment.

[0035] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
