Description

Tomato Climbing Trough Technical Field

[0001] This utility model relates to the field of climbing frame technology, specifically to a climbing frame for tomato cultivation. Background Technology

[0002] In the process of tomato cultivation, the growth of the plant and the yield and quality of the fruit are affected by a variety of factors. A suitable support structure plays a crucial role in the healthy growth of tomato plants. Tomatoes are vine plants that cannot grow upright on their own and need external support to climb upwards to fully extend their branches and leaves. If there is a lack of effective support, the plant is prone to growing on the ground, which not only leads to unreasonable use of space but may also cause branches and leaves to shade each other, resulting in poor ventilation and lighting conditions.

[0003] The stability of existing climbing frames is generally insufficient, especially in severe weather such as strong winds, where they are prone to swaying, tilting or even collapsing. This not only directly damages tomato plants and interrupts their normal growth process, but may also cause fruit to fall off, seriously affecting yield. In addition, the existing anchoring methods are usually simple and cannot effectively resist external forces, making it difficult to ensure the stability of the climbing frame in various environments. Summary of the Invention

[0004] To address the aforementioned problems, this utility model provides a tomato planting climbing frame, which features flexible adjustment of height and spacing, strong stability and wind resistance, thus solving the problems of traditional climbing frames being unable to adapt to different planting environments and lacking stability, making them prone to damage in severe weather.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: a tomato planting climbing frame, comprising three climbing rods, two adjusting rods fixedly installed on the outer side of each climbing rod, several trapezoidal adjusting slots on one side of each adjusting rod, a telescopic groove at the bottom of each climbing rod, a telescopic rod movably installed inside the telescopic groove, several threaded grooves on the outer side of each telescopic rod, and a spinning-type expanding claw anchoring assembly at the bottom of each telescopic rod for improving stability and wind resistance. Two adjusting components for adjusting the distance between the three climbing rods are provided between the three climbing rods, and the trapezoidal adjusting slots are used in conjunction with the adjusting components.

[0006] As a preferred embodiment of this utility model, the spin-forming expander anchor assembly includes an installation rod, which is fixedly installed at the bottom of a telescopic rod. The installation rod has a threaded outer side, and a threaded sleeve is threadedly connected to the outer side of the installation rod. A movable ring is movably installed on the outer side of the threaded sleeve via a groove. Three rectangular slots are equidistantly formed on the outer side of the movable ring. Movable claws are movably installed inside the rectangular slots via a round rod. Several barbs are fixedly installed on one side of each movable claw. A trapezoidal compression ring is fixedly installed on the outer side of the installation rod, and the trapezoidal compression ring is located at the bottom of the three movable claws. A conical protrusion is fixedly installed at the bottom of the installation rod.

[0007] As a preferred embodiment of this utility model, the adjustment component includes a triangular adjustment frame disposed between three climbing rods. Each of the three vertices of the triangular adjustment frame has a rectangular hole. An adjustment rod is movably installed inside the rectangular hole. A rectangular mounting groove is formed on one side of the rectangular hole. A trapezoidal pin is movably installed inside the rectangular mounting groove. The trapezoidal pin cooperates with a trapezoidal adjustment slot. A spring is fixedly installed at one end of the trapezoidal pin, and the other end of the spring is fixedly installed to one side of the rectangular mounting groove.

[0008] As a preferred embodiment of this utility model, a circular hole is provided on the outer side of the climbing rod, the circular hole corresponds to a threaded groove, and a bolt is movably fitted inside the circular hole, the bolt passing through the circular hole and threadedly connected to the threaded groove.

[0009] As a preferred embodiment of this utility model, the bottom of the movable claw is set with an inclined surface, which is adapted to the inclined surface of the top of the trapezoidal extrusion ring, and a handle is symmetrically fixedly installed on the outer side of the threaded sleeve.

[0010] As a preferred embodiment of this utility model, the inclined surface of the trapezoidal pin is adapted to the inclined surface in the trapezoidal adjusting groove.

[0011] The beneficial effects of this utility model are as follows:

[0012] This utility model achieves flexible adjustment of height and spacing by setting up climbing rods, adjusting rods, and telescopic rods. The trapezoidal adjustment slot of the adjusting rod, together with the trapezoidal pin and spring of the triangular adjusting frame, allows the climbing rod spacing to be adjusted by pushing and pulling the adjusting rod as needed, so as to meet the ventilation and lighting needs of plants at different growth stages. The telescopic rod, through the cooperation of bolts and threaded grooves, can adjust the extension length as needed to adapt to different planting environments and varieties.

[0013] A spinning-type expanding claw anchoring component is installed at the bottom of the telescopic pole to improve the stability and wind resistance of the climbing frame. The threaded sleeve is manually rotated to drive the movable ring to expand the movable claw and insert it into the soil. The barbs enhance the grip and prevent the frame from swaying and collapsing in strong winds, thus ensuring plant growth. The conical protrusion at the bottom of the pole facilitates the insertion of the component into the soil and improves the ease of installation. Attached Figure Description

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-6 are the preferred embodiments of this utility model. The utility model will be further described below with reference to Figures 1-6.

[0023] The tomato climbing frame includes three climbing poles 1. Two adjusting rods 2 are fixedly installed on the outer side of the climbing poles 1. Several trapezoidal adjusting slots 3 are opened on one side of the adjusting rods 2. The bottom of the climbing poles 1 has a telescopic groove 4. A telescopic rod 5 is movably installed inside the telescopic groove 4. Several threaded grooves 6 are opened on the outer side of the telescopic rod 5. The bottom of the telescopic rod 5 is equipped with a spinning-type expanding claw anchoring component to improve stability and wind resistance. Two adjusting components are set between the three climbing poles 1 to adjust the distance between the three climbing poles 1. The trapezoidal adjusting slots 3 are used in conjunction with the adjusting components.

[0024] In this implementation scheme, climbing rods 1 provide a vertical support for the tomato plants, bearing the weight and tension of the plants during growth. This forms the basic structure of the entire climbing frame. Adjustable rods 2, in conjunction with the adjustment components, utilize trapezoidal adjustment slots 3 to adjust the spacing between the climbing rods 1. This allows for flexible adjustment based on the spatial needs of the tomato plants at different growth stages, ensuring ventilation and light penetration, and promoting healthy growth. The trapezoidal adjustment slots 3, in conjunction with the trapezoidal pins 19 in the adjustment components, form multiple adjustable positioning nodes, enabling precise locking of the position of the adjustable rods 2 and thus controlling the spacing between the climbing rods 1. This meets the diverse spatial needs of the plants at different growth stages. Telescopic grooves 4 provide space for the telescopic rods 5, allowing them to extend and retract, laying the foundation for the height adjustment function of the climbing frame. Different planting environments and different tomato varieties have different height requirements. The telescopic rod 5 extends and retracts within the telescopic groove 4. Through cooperation with the threaded groove 6 and bolts, the overall height of the climbing frame can be flexibly adjusted. When the telescopic rod 5 is adjusted to the appropriate height, it is threadedly connected to the threaded groove 6 by the bolts, which securely locks the telescopic rod 5 within the telescopic groove 4. The spinning-type expanding claw anchoring component, through the cooperation of components such as the threaded sleeve 9, the movable ring 10, and the movable claw 11, causes the movable claw 11 to expand outwards and insert into the soil when the threaded sleeve 9 is rotated. This increases the contact area and friction with the soil, significantly improving the stability and wind resistance of the climbing frame, preventing the frame from tilting or collapsing, and protecting the plants for safe growth. The adjustment component allows for convenient adjustment of the distance between the three climbing rods 1, ensuring that the plants have suitable growing space at different growth stages.

[0025] Specifically, the spinning-type expanding claw anchoring assembly includes an installation rod 7, which is fixedly installed at the bottom of the telescopic rod 5. The outer side of the installation rod 7 is threaded with a thread 8, and a threaded sleeve 9 is threadedly connected to the outer side of the installation rod 7. A movable ring 10 is movably installed on the outer side of the threaded sleeve 9 through a groove. Three rectangular slots are equidistantly opened on the outer side of the movable ring 10. Movable claws 11 are movably installed inside the rectangular slots through a round rod. Several barbs 12 are fixedly installed on one side of the movable claws 11. A trapezoidal compression ring 13 is fixedly installed on the outer side of the installation rod 7. The trapezoidal compression ring 13 is located at the bottom of the three movable claws 11. A conical protrusion 14 is fixedly installed at the bottom of the installation rod 7.

[0026] In this embodiment, by setting one end of the installation rod 7 to be securely connected to the bottom of the telescopic rod 5, an installation foundation is provided for the entire anchoring assembly, bearing the weight and force of other components and ensuring the stability of the assembly structure. The thread 8 and the threaded sleeve 9 cooperate, and by rotating the threaded sleeve 9, it moves up and down along the installation rod 7, providing a power transmission path for the expansion action of the movable claw 11. When the threaded sleeve 9 rotates, it moves along the thread 8 on the outside of the installation rod 7. During the downward movement, it squeezes the movable ring 10, thereby pushing the movable claw 11 to expand outward. The movable ring 10 is sleeved on the outside of the threaded sleeve 9 and is movably connected to the threaded sleeve 9 through a groove. The rectangular groove provides space for the installation and rotation of the movable claw 11. When the threaded sleeve 9 rotates, it does not drive the movable ring 10 to rotate, but transmits the downward pressure of the threaded sleeve 9 to the movable claw 11, causing the movable claw 11 to rotate around the circular rod, realizing the expansion action of the movable claw 11. The movable claw 11 is in direct contact with the soil. The component that contacts and provides anchoring force expands into the soil by rotating, increasing the contact area and friction between the component and the soil, significantly improving the stability and wind resistance of the climbing frame. The barb 12 is fixedly installed on one side of the movable claw 11. After being inserted into the soil, the unidirectional gripping force of the barb 12 effectively enhances the gripping force between the movable claw 11 and the soil, improving the stability of the climbing frame in the soil and resisting external forces. The barb 12 further enhances the interlocking with the soil, preventing the climbing frame from being pulled out. The trapezoidal compression ring 13 has a trapezoidal inclined surface that matches the bottom inclined surface of the movable claw 11. When the movable ring 10 is pressed down, it guides the movable claw 11 to expand in a predetermined direction, ensuring accurate and efficient expansion action, while providing support for the movable claw 11. The conical protrusion 14 has a sharp conical structure that effectively reduces the resistance to insertion into the soil, making it easy for the entire spin-pressed expansion claw anchoring component to be quickly and smoothly inserted into the soil, improving installation efficiency and convenience.

[0027] Specifically, the adjustment component includes a triangular adjustment frame 15, which is positioned between three climbing rods 1. Each of the three vertices of the triangular adjustment frame 15 has a rectangular hole 16. The adjustment rod 2 is movably installed inside the rectangular hole 16. A rectangular mounting groove 17 is provided on one side of the rectangular hole 16. A trapezoidal pin 19 is movably installed inside the rectangular mounting groove 17. The trapezoidal pin 19 works in conjunction with the trapezoidal adjustment slot 3. A spring 18 is fixedly installed at one end of the trapezoidal pin 19, and the other end of the spring 18 is fixedly installed on one side of the rectangular mounting groove 17.

[0028] In this embodiment, a triangular adjustment frame 15 is set as the main frame of the adjustment component, positioned between the three climbing rods 1, providing stable support and connection for the entire adjustment structure. This ensures that the three climbing rods 1 can form a stable and adjustable overall structure. The rectangular hole 16 provides movement space for the adjustment rod 2, allowing it to slide smoothly within the rectangular hole 16 and serving as a guide. The rectangular mounting groove 17 provides installation space for the trapezoidal pin 19 and the spring 18, ensuring they can be installed and function in the appropriate positions. The trapezoidal pin 19 cooperates with the trapezoidal adjustment slot 3 on the adjustment rod 2. When it is necessary to adjust the distance between the three climbing rods 1, external force overcomes the spring 18's elasticity. The force causes the trapezoidal pin 19 to disengage from the trapezoidal adjustment slot 3. At this time, the adjustment rod 2 can slide within the rectangular hole 16 to adjust the spacing. After adjusting to the appropriate position, the external force is released, and under the elastic force of the spring 18, the trapezoidal pin 19 inserts into the corresponding trapezoidal adjustment slot 3, locking the adjustment rod 2 and fixing the spacing between the climbing rods 1. The spring 18 provides a reset elastic force for the trapezoidal pin 19. When the external force is removed, the spring 18 pushes the trapezoidal pin 19 back to the position that cooperates with the trapezoidal adjustment slot 3, realizing automatic locking. The elastic force of the spring 18 ensures a tight fit between the trapezoidal pin 19 and the trapezoidal adjustment slot 3, enhancing the stability of the lock and preventing the adjustment rod 2 from loosening due to vibration or other reasons during use.

[0029] Specifically, a circular hole is provided on the outer side of the climbing rod 1, which corresponds to the threaded groove 6. A bolt is movably fitted inside the circular hole, and the bolt passes through the circular hole and is threadedly connected to the threaded groove 6.

[0030] In this implementation scheme, a circular hole is provided on the outside of the climbing pole 1, precisely corresponding to the threaded groove 6 on the telescopic pole 5. This provides a through-hole for the bolt, serving as a positioning and guiding function. This ensures that the bolt can accurately align with the threaded groove 6, enabling the fixing and adjustment of the telescopic pole 5. When the height of the climbing frame needs to be adjusted, the bolt is loosened manually with a wrench, allowing the telescopic pole 5 to extend and retract freely within the telescopic groove 4. After adjusting to the appropriate height, the bolt is tightened manually with a wrench to securely lock the telescopic pole 5 in its current position, ensuring the stability of the climbing frame's height and preventing it from shifting under the weight of the plant and external forces. The threaded groove 6, in conjunction with the bolt, provides an internal thread structure for the bolt to engage. The meshing of the threads generates a tightening force, which, together with the bolt, achieves precise adjustment and secure locking of the telescopic pole 5's position, ensuring that the climbing frame maintains reliable support performance at different heights.

[0031] Specifically, the bottom of the movable claw 11 is set with an inclined surface, which is adapted to the inclined surface at the top of the trapezoidal extrusion ring 13, and a handle is symmetrically fixedly installed on the outside of the threaded sleeve 9.

[0032] In this embodiment, the bottom of the movable claw 11 is set with an inclined surface. Through the design of the inclined surface at a specific angle, it cooperates with the top inclined surface of the trapezoidal compression ring 13. When the threaded sleeve 9 drives the movable ring 10 to move downward, the bottom inclined surface of the movable claw 11 is compressed, generating a component force along the inclined surface direction. This drives the movable claw 11 to rotate around the round rod and expand outward, realizing the action of inserting into the soil. The top inclined surface of the trapezoidal compression ring 13 provides a guiding and force-applying surface for the expansion of the movable claw 11. It fits tightly with the bottom inclined surface of the movable claw 11, accurately guiding the movable claw 11 to expand in a predetermined direction and angle, so that the movable claw 11 inserts into the soil evenly and stably. The screw-in screw-in expansion claw anchor assembly is embedded in the soil, enhancing its anchoring stability and reliability. It also provides reverse support for the movable claw 11, ensuring structural stability during expansion. A handle is fixedly installed on the outside of the threaded sleeve 9 for easy gripping by operators. When adjusting the screw-in screw-in expansion claw anchor assembly by rotating the threaded sleeve 9, the handle significantly enhances the stability and control of hand force application, reducing operational difficulty and hand fatigue. This allows installers to more easily and efficiently move the movable ring 10 downwards by rotating the threaded sleeve 9, thereby expanding and contracting the movable claw 11, improving the convenience and efficiency of the entire anchor assembly installation and disassembly process.

[0033] Specifically, the inclined surface of the trapezoidal pin 19 is adapted to the inclined surface inside the trapezoidal adjusting slot 3.

[0034] In this embodiment, by setting the inclined surface of the trapezoidal pin 19, during the adjustment process, when an external force is applied to the adjusting rod 2 to make it move, the inclined surface of the trapezoidal pin 19 and the inclined surface in the trapezoidal adjusting groove 3 will slide relative to each other. Through the cooperation between the inclined surfaces, the resistance of the pin moving in the groove is reduced, making the pushing and pulling operation of the adjusting rod 2 smoother. The inclined surface in the trapezoidal adjusting groove 3 and the inclined surface of the trapezoidal pin 19 are closely cooperated to provide guidance and support for the sliding and locking of the pin. When the adjusting rod 2 moves into place, the trapezoidal pin 19 is embedded in the groove under the elastic force of the spring 18, and the inclined surfaces of the two abut against each other to form a stable locking structure.

[0035] In summary: When using this utility model, based on the tomato planting scale, plant spacing, and height requirements, the telescopic rod 5 is inserted into the telescopic groove 4 at the bottom of the climbing rod 1. The extension length of the telescopic rod 5 is adjusted according to the expected growth height of the tomato plants, ensuring that the threaded groove 6 on the outer side of the telescopic rod 5 is precisely aligned with the round hole on the outer side of the climbing rod 1. A bolt is passed through the round hole on the outer side of the climbing rod 1 and threaded into the threaded groove 6. The bolt is then manually tightened with a wrench to fix the position of the telescopic rod 5, thus completing the height adjustment of the climbing frame. The triangular adjustment frame 15 is then placed between the three climbing rods 1, with the adjustment rod 2 inserted into the three vertices of the triangular adjustment frame 15. Inside the rectangular hole 16, hold the climbing rod 1 and press it firmly so that the adjusting rod 2 presses against the trapezoidal pin 19. The trapezoidal pin 19 presses against the spring 18 inside the rectangular mounting groove 17. When the adjusting slot 3 on the adjusting rod 2 corresponds to the trapezoidal pin 19, the spring 18 releases its elasticity, inserting the trapezoidal pin 19 into the adjusting slot 3. Depending on the space required for plant growth, manually push the adjusting rod 2 inward or outward. Under the action of the spring 18, the trapezoidal pin 19 slides along the trapezoidal adjusting slot 3. After adjusting to the appropriate distance, release the adjusting rod 2. The spring 18 pushes the trapezoidal pin 19 into the corresponding trapezoidal adjusting slot 3, locking the adjusting rod 2. Position the climbing pole 1 and adjust the spacing. Holding the climbing pole 1, align the conical protrusion 14 at the bottom of the mounting pole 7 with the ground and press down firmly to insert the mounting pole 7, movable ring 10, and movable claw 11 into the soil until the movable ring 10 is completely buried. Hold the handle on the outside of the threaded sleeve 9 and rotate the threaded sleeve 9 clockwise to move it downwards along the thread 8 on the outside of the mounting pole 7. As the threaded sleeve 9 moves downwards, it squeezes the movable ring 10, which pushes the movable claw 11. This causes the bottom slope of the movable claw 11 to press against the top slope of the trapezoidal compression ring 13. Under the pressure, the movable claw 11 expands around the circular pole and inserts into the surrounding area. The barbs 12 embed into the soil, significantly enhancing the climbing frame's grip on the ground, completing the anchoring, and improving the climbing frame's wind resistance and stability. After use, hold the outer handle of the threaded sleeve 9 and rotate the threaded sleeve 9 counterclockwise to retract the movable claw 11. Pull the climbing rod 1 upwards to remove the spin-pressed expanding claw anchoring assembly from the soil. Clean the soil off the assembly surface and pull the adjusting rod 2 outwards to compress the spring 18, causing the trapezoidal pin 19 to disengage from the trapezoidal adjusting slot 3. Completely pull the adjusting rod 2 out of the rectangular hole 16 to separate the triangular adjusting frame 15 from the climbing rod 1. Store all components properly for future use.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
