[0026] It should be noted that the relative terms such as first and second, and the like are used herein solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any such actual relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without more limitations, an element defined by an "including a" statement does not exclude the existence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0027] As Figure 1 shown, a vegetable planting frame according to the present application comprises a base 1, an adjustable column 2, a crossbeam 3 and a planting tray 4. In addition, the frame also comprises a hand wheel type height adjusting device 5 for height adjustment.

[0028] The base 1 provides the basic support for the entire planting frame, which is stably placed on the ground or other platform to ensure the stability of the entire structure. The upper surface of the base 1 has a plurality of mounting holes or connection points for securely combining the adjustable column 2 therewith. This design ensures the close connection between the column and the base 1, while also facilitating disassembly and reassembly.

[0029] The adjustable column 2 is installed above the base 1 and provides structural support for the planting frame in the vertical direction. It is provided with positioning holes and corresponding threaded interfaces inside or outside, which cooperate with the hand-tightened locking nuts to realize the selection and fixation of different height positions. This allows users to adjust the height of the column according to their needs without the need for additional tools. The design of the hand-tightened locking nuts takes into account convenience and practicality.

[0030] The horizontal beams 3 are horizontally connected to the top of the plurality of adjustable columns 2 to form a stable load bearing platform. This part is used as an important component to bear the weight of the trays and the corresponding vegetation required for planting. The material should be selected to have good load bearing performance and a certain degree of toughness, such as metal or high-quality composite materials, etc., to ensure safety during use.

[0031] The planting trays 4 are arranged on the upper surface of the horizontal beams 3 to load various vegetable pots. The trays can be designed with a certain inclination to drain excess water, and the bottom is provided with a plurality of small holes to promote air circulation and root respiration. In addition, it can also be equipped with a slide rail system to make replacement and cleaning more convenient and efficient.

[0032] The hand wheel type height adjustment device 5 is installed on one side of the adjustable column 2. This device is composed of a knob with an indicating symbol direction and a positioning pin, and the direction knob has clear scale lines 12, which enable the operator to accurately know the degree of rotation and the set position reached without precise measuring instruments. Users only need to turn the hand wheel slightly to change the final placement of the entire structure without exerting much physical effort, which is very suitable for users with relatively weak physical ability, such as the elderly.

[0033] Specifically, the base 1 can be made of cast aluminum or thick steel plate to ensure sufficient strength and flatness. The connecting interface can be reinforced by welding and equipped with sealing washers to prevent moisture from entering and causing rust. The adjustable column 2 is made of hollow steel pipe, with stainless steel nuts embedded at key connection points to ensure durability and reliability after repeated adjustments. The pre-set positioning holes are generated by stamping or mechanical processing. The horizontal beam 3 can be made of rectangular steel pipe with reinforcing ribs welded on both sides to enhance lateral stiffness. The end is drilled with a round hole to cooperate with the screw to lock and fix the column. The components in the hand wheel type height adjustment device 5 are usually metal and are installed in place after precise cutting and polishing. The surface of the direction knob is formed with clear line texture through fine turning process to facilitate identification and control. The internal worm and gear transmission principle is used to increase the force arm to allow users to drive the whole up and down with less force.

[0034] In order to facilitate the operation of the elderly or those with weak physical strength, the vegetable planting frame adopts a hand wheel type height adjustment method, which is safer, more intuitive and easier to master than traditional hydraulic or electric lifting schemes. The rotation angle mark helps users quickly find the target displacement amplitude and avoid accidental changes caused by misoperation. In addition, since it does not rely on power sources or complex control systems, the daily maintenance difficulty is reduced. The whole mechanism fully considers the actual needs of such special groups and provides a more humanized solution.

[0035] In one embodiment, continuing to refer to Figure 1The base 1 of the vegetable planting frame of the present application is provided with a roller assembly 6 at the bottom, which enables the user to conveniently move the entire planting frame when the height or position needs to be adjusted. In order to ensure that the base 1 has sufficient stability and structural strength, reinforcing rib plates 16 are arranged at the four corners of the base 1 to prevent deformation of the base 1 due to external forces, thereby affecting the overall service life and stability.

[0036] Specifically, by adding the roller assembly 6, during daily use, when the position of the planting frame needs to be changed or maintenance, carrying, etc. operations are performed, manual difficulties and possible ground damage caused by weight problems can be avoided. The reinforcing rib plates 16 are arranged at the four corner positions of the base 1, which not only strengthen the connection firmness of the edges of the base 1, but also enhance the dispersion ability of the entire base to external forces. In addition, such design also improves the shear resistance of the base 1 itself, which provides more reliable support and protection for the upper components.

[0037] For example, the roller assembly 6 can be directly installed at the four corners of the bottom surface of the base 1 below by bolts or other suitable fixing means, and ensure that it can roll smoothly without excessive resistance. At the same time, the two ends of each reinforcing rib plate 16 are continuously welded or fixed by riveting with the side surface of the base 1, so as to become an indivisible whole, so that the base 1 can better bear various loads from the top. In addition, the reinforcing rib plate 16 itself can also be made of high-strength metal materials such as stainless steel or aluminum alloy plate, which not only reduces the weight itself but also ensures the firmness of the structure.

[0038] In one embodiment, the adjustable column 2 of the vegetable planting frame of the present application is designed with an internal telescopic rod 7. Through this structural design, the height of the entire planting frame can be flexibly adjusted to adapt to different application scenarios and user needs. The adjustable column 2 is connected with the base 1, and the main part is installed on the upper surface of the base 1, and provides stable structural support in the vertical direction. Inside the adjustable column 2, a telescopic rod 7 that can slide longitudinally is configured, so that the overall height of the planting frame can be continuously changed within a certain range, while ensuring good stability in various height states. This structural design fully considers the different requirements for plant growth environment during planting, such as light intensity adjustment and space layout planning, etc.

[0039] In a specific implementation, for example, in order to ensure the stability of the telescopic rod 7 and the column during height adjustment and the convenience of operation, a high-precision guide device is used between the two, which not only prevents shaking but also has good wear resistance, thereby prolonging the service life of the overall structure. In addition, the column is equipped with a set of manual adjustment mechanism, when the operator wants to change the height, just loosen the locking part to make the telescopic rod 7 freely ascend and descend to the appropriate position, and then firmly fix it to complete the height adjustment operation process. This manual handwheel type adjustment method is intuitive and easy to master, and is very suitable for popularization and application in actual use scenarios.

[0040] In one embodiment, the adjustable column 2 of the vegetable planting frame of the present application is provided with preset positioning holes for cooperating with the locking nuts to realize the height adjustment and fixation of the structure. The positioning holes are uniformly distributed on the adjustable column 2, ensuring that users can flexibly select the appropriate fixed position when different height requirements are needed. This design allows users to adjust the overall height according to the specific cultivation environment, while ensuring the stability of the structure, and also provides flexibility in operation. The circular through hole 8 form of the positioning hole not only facilitates processing, but also effectively reduces material waste. The hole diameter is carefully calculated and designed to perfectly match the locking nut, realizing a stable and reliable fixation function without affecting the convenience of use.

[0041] Specifically, the circular through hole 8 can be opened on the adjustable column 2 according to the predetermined interval during the production stage by using a numerical control machine tool or a special punch equipment, and the consistency of the diameters of all through holes is strictly guaranteed to meet the requirements of the locking nut. During installation, the user can quickly and stably fix the position of the column by manually rotating the locking nut into the corresponding level of the positioning hole, thereby ensuring that the height adjustment range of the entire device is controllable and reliably fixed at the desired height. For example, during assembly or later adjustment, after placing the handwheel type height adjustment device 5 at the appropriate height, the selected locking nut is inserted into the corresponding positioning hole to complete the fixation.

[0042] In one embodiment, as shown in Figure 2 The beam 3 of the vegetable planting frame of the present application is provided with a locking bolt 9 at both ends, which is used to fix the connection position of the beam 3 and the adjustable column 2. This feature aims to enhance the stability and reliability of the planting frame structure, ensuring that each component will not easily loosen or shift when subjected to external force or other actions. Through the effective use of the locking bolt 9, the beam 3 can be firmly attached to the adjustable column 2 at the set height, avoiding the influence of external conditions (such as wind force, vibration during transportation, etc.) on the relative position between the beam 3 and the column.

[0043] Specifically, in one embodiment, the two ends of the crossbeam 3 are threaded or have through holes to receive locking bolts 9. At the same time, to make the locking operation more convenient, corresponding holes can usually be provided at appropriate positions of the stand. When installing, the crossbeam 3 needs to be lifted to the preset height, aligned with the positioning holes of the stand, and the locking bolts 9 are tightened to achieve close connection. In this way, even if it is in an outdoor environment for a long time or in an unfavorable condition, it can maintain a stable state. In addition, according to different actual conditions, bolts of different lengths can also be selected to meet specific application requirements, ensuring the applicability and adjustment flexibility while improving the firmness and safety of the entire system.

[0044] In one embodiment, continuing to refer to Figure 2 , the bottom of the planting tray 4 of a vegetable planting frame of the present application is provided with a buffer pad layer 10. The structure design aims to provide a buffer transition surface between the planting tray 4 and the crossbeam 3 to avoid mechanical damage or wear that may occur during long-term use, especially during handling and position adjustment. By being installed at the bottom area of the planting tray 4, the buffer pad layer 10 can effectively reduce the problem of direct metal component contact caused by external force impact.

[0045] Specifically, the buffer pad layer 10 is composed of materials with good elasticity and wear resistance, such as high-density polyethylene foam or silicone rubber. These materials not only can absorb energy when subjected to external stress, but also can restore the original shape to a certain extent, prolonging the service life of the entire planting frame system. In addition, the buffer pad layer 10 also has certain moisture-proof and corrosion-resistant properties to adapt to different environmental conditions.

[0046] For example, when making the planting tray 4, a groove of appropriate size can be pre-made, and the selected material can be cut according to actual needs, and then it is firmly adhered to the inner side surface of the groove using environmentally friendly adhesive, thereby completing the effective combination of the buffer pad layer 10 and the main body of the planting tray 4. The advantage of this is to ensure that the connection is smooth and uninterrupted, so that the two are tightly attached and not easy to fall off, thereby achieving good shock absorption and protection effect.

[0047] In one embodiment, the handwheel type height adjustment device 5 of a vegetable planting frame of the present application is installed on one side of the adjustable stand 2 for height adjustment by rotating. As Figure 4As shown, the hand wheel type height adjustment device 5 not only provides a convenient manual adjustment method, but also has an advanced torque monitoring function. The rotating shaft position is provided with a torque sensor 11, so that the operator can monitor the change of the rotating torque in real time during the adjustment process. Through this feature, the operation force of the hand wheel type height adjustment device 5 can be more accurately controlled, ensuring stable operation and avoiding damage or misalignment due to excessive force. The application of the torque sensor 11 also enables the system to better feedback the adjustment state, facilitating user fine tuning.

[0048] Specifically, the installation position of the hand wheel type height adjustment device 5 cooperates with the base 1, and in a direction perpendicular to the base 1, the rotating shaft of the device passes through the adjustable column and interfaces with the internal gear system to drive the lifting action of the column relative to the base 1. The torque sensor 11 on the rotating shaft is located in a fixed bracket between the rotating shaft and the hand wheel, adjacent to the gear mechanism. This design layout helps the sensor accurately detect the mechanical torque converted from the manual force, thereby providing a reference for adjustment.

[0049] For example, this arrangement can be realized by selecting a high-sensitivity, miniaturized torque sensor 11 to realize this feature. The sensor is directly installed in the key stress area of the rotating shaft, using strain gauges or Hall effect elements to sense the change in torsional load generated during rotation, while equipped with a data interface to transmit the measured information to an external display or other control system for reading and analysis. This not only simplifies the installation process, but also ensures detection accuracy and response speed. In addition, the torque sensor 11 is packaged in a fixed structure near the rotating shaft with waterproof and dustproof seals, effectively protecting the sensor from external environmental factors, prolonging service life and operational reliability.

[0050] In one embodiment, the hand wheel type height adjustment device 5 of the vegetable growing rack of the present application is equipped with an automatic reset spring 13 (see Figure 3 ). The design of this device enables the hand wheel type height adjustment device 5 to quickly and automatically return to the initial position after the user stops manual adjustment. This mechanism not only improves user operation convenience, but also effectively reduces the aging and wear of mechanical parts during long-term use. Specifically, the installation position of the automatic reset spring 13 is located between the hand wheel type height adjustment device 5 and the adjustable column 2, which plays a key role in the internal structure, ensuring the rebound effect after each rotation.

[0051] The hand wheel type height adjustment device 5 includes a handle for manual adjustment, which can move the beam 3 and the planting tray 4 carried thereon up and down by rotating. The automatic reset spring 13 is arranged to act immediately when the handle is released, ensuring that the device can smoothly return to the initial state, maintaining the stability of the equipment while enhancing the safety performance.

[0052] In this design, the automatic reset function of the handwheel type height adjustment device 5 is mainly realized through a carefully designed mechanical linkage. Specifically, one end of the spring 15 is fastened to the shell of the adjustment device, and the other end is connected to the rotating shaft of the height adjustment handle for operation. When the user rotates the height adjustment handle, the spring is compressed or stretched with the rotation of the handle; once the hand leaves the handle, the spring will release the stored energy, driving the handle together with the adjustment mechanism back to the original position. During this process, the spring is always working within a controllable range, neither over-contracted nor relaxed, thus effectively realizing the automatic reset operation. Such a mechanical structure is simple and reliable, easy to manufacture and maintain, and at the same time ensures that the device can operate normally under different load conditions, meeting the actual application requirements of the vegetable growing rack.

[0053] In one embodiment, referring to Figure 4 The positioning pin of the vegetable growing rack according to the present application is covered with a protective rubber sleeve 14. This design aims to provide reliable protection for the positioning pin, avoiding scratches or damage to the user's hands during operation and handling. At the same time, the protective rubber sleeve 14 can play a certain damping role, reducing external vibration transmission when the handwheel type height adjustment device 5 rotates, ensuring that the device adjustment is more stable and smooth. In addition, this structure also enhances the user's grip comfort.

[0054] The selection and installation position of the protective rubber sleeve 14 are carefully considered. The protective rubber sleeve 14 is made of materials with good weather resistance and aging resistance, which can withstand the influence of the external environment for a long time. The protective rubber sleeve 14 closely fits the outside of the positioning pin and will not loosen or fall off after long-term use. During specific installation, the protective rubber sleeve 14 is firmly attached to the positioning pin through processes such as thermoplastic forming, without affecting the function of the positioning pin or hindering its normal connection with other components.

[0055] For example, when the technical personnel need to fine-tune the handwheel type height adjustment device 5, the presence of the protective rubber sleeve 14 will not affect its operation accuracy and convenience. Specifically, the technical personnel rotate the direction knob to change the height of the adjustable column 2, and during this period, the protective rubber sleeve 14 protects the positioning pin from accidental damage, ensuring that the cooperative work between components during the height adjustment process proceeds smoothly. At the same time, when the hand-tightening locking nut is fixed, it can also effectively prevent the inconvenience caused by direct contact between the nut and the hand.

[0056] In one embodiment, the hand wheel surface of the hand wheel type height adjustment device 5 of the vegetable planting frame of the present application is provided with a rubber grip 15. This design not only improves the comfort of the user's grip when adjusting the height, but also enhances the friction of the hands and reduces the risk of slipping. The design of the rubber grip 15 conforms to the principle of ergonomics, making the adjustment action more relaxed and precise.

[0057] Specifically, the hand wheel type height adjustment device 5 is installed on one side of the adjustable column 2, and the hand wheel surface is covered with a rubber grip. This grip closely fits the surface of the hand wheel and is fixed by adhesive or embedded process, ensuring its durability and long-term stability. Because rubber has good elasticity and shock-absorbing properties, this design can effectively buffer the force exerted by the user when turning, thereby protecting the user's joints and muscles from injury.

[0058] In addition, the central part of the hand wheel is made of metal or high-strength plastic material, which can withstand a large torsion force, ensuring the safety and reliability of the entire device. By wrapping a layer of rubber around the outer edge of the hand wheel, the normal operation of the hand wheel type height adjustment device 5 is not affected, and the convenience of use and user experience are significantly improved. In order to meet the needs of different occasions, the rubber grip 15 can be selected in different colors and textures.

[0059] Specifically, the rubber grip 15 can be molded by custom mold injection molding, with a groove or buckle structure matching the hand wheel designed inside. When installing, you only need to insert the hand wheel into the rubber grip 15 and lock it tightly to ensure that there is no relative displacement between the two, thereby achieving a stable installation effect. For example, the inner wall of the rubber grip 15 is provided with a plurality of anti-skid racks, which can increase the friction resistance when cooperating with the hand wheel, ensuring the stability during the adjustment process.

[0060] In actual operation, when the device is in use, first place the base 1 at the predetermined installation position to provide stable support. Then, install the adjustable column 2 above the base 1 and fix the column by hand-tightening the locking nut. Next, connect the cross beam 3 horizontally on the top of the adjustable column 2 to form a stable structural frame. Then, place the planting tray 4 on the upper surface of the cross beam 3 for loading vegetable pots. In order to adjust the height of the planting frame, the hand wheel type height adjustment device 5 installed on one side of the adjustable column 2 can be turned to raise or lower the height of the column on the base 1 as needed. During the adjustment process, the angle scale line 12 on the direction knob ensures the accuracy of the adjustment, and the positioning pin ensures the stable locking of the column at the set height. In this way, the user can easily adjust the height of the entire planting frame according to the planting needs or space limitations, ensuring that the plants obtain the best growing conditions.

[0061] The above are preferred embodiments of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles described in the present application, can make several improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
