Description

Technical Field

[0001] This utility model relates to the field of support frame technology, and in particular to a foldable pear tree branch support frame. Background Technology

[0002] In pear tree cultivation, branch support frames play a crucial role in ensuring reasonable growth space and shape for pear tree branches, and preventing branches from bending or being damaged due to fruit weight or natural factors, which would affect fruit yield and quality. Whether in large-scale pear orchards or small orchards, reliable branch support frames are essential to assist pear tree growth. In practical applications, such as supporting new pear tree branches in spring to fix their direction, and supporting them to bear the weight of the branches during the summer fruit enlargement period, foldable pear tree branch support frames typically require the following technologies in practical applications:

[0003] 1. Flexible angle adjustment technology can be precisely adjusted according to the different growth angles of pear tree branches to ensure that the support frame fits tightly with the branches and provides effective support;

[0004] 2. Stable telescopic and fixing technology: The telescopic structure of the support frame must be stable and reliable, with the length adjustable according to actual needs, and it must be firmly fixed to prevent loosening during the support process;

[0005] 3. Convenient folding and unfolding technology, which makes it easy to fold and store when not in use, reducing space occupation, and can be quickly unfolded and installed when in use;

[0006] 4. Durable materials and structural technology: Made of sturdy and durable materials, it has good wind and corrosion resistance, adapts to the changing outdoor natural environment, and extends the service life of the support frame.

[0007] Currently, various devices and methods are used to support pear tree branches. Some fruit growers use traditional wooden or bamboo sticks, binding the branches together to provide support. Others use fixed metal support frames, while some devices employ adjustable, openable support frames.

[0008] The existing adjustable-angle pear tree branch support frame has a drawback: to accommodate different branch growth angles, the adjustable-angle support frame is usually fixed by screwing bolts into the two slots. When determining the rotation angle, the lack of elastic locking and limiting function makes it impossible to stably support the adjustment seat in the screw-in installation position. Users need to support the support to ensure that there is no rotational deviation while tightening the bolts. This process is cumbersome and often takes a lot of time. When multiple support frames need to be installed, the cumulative operation time will increase significantly, reducing work efficiency. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a foldable pear tree branch support frame. It solves the problem that adjustable support frames, designed to accommodate different branch growth angles, typically rely on bolts aligned with two slots for tightening. However, the lack of elastic locking mechanisms prevents the adjustable base from being stably supported at the tightening position when determining the rotation angle. Users must simultaneously support the branch to prevent rotational shift while tightening the bolts, a cumbersome and time-consuming process. When multiple support frames need to be installed, the cumulative operation time increases significantly, reducing work efficiency.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A foldable pear tree branch support frame includes a telescopic reinforcing rod. An adjustment mechanism for adapting to branch angles is rotatably connected inside the telescopic reinforcing rod. The adjustment mechanism includes an H-shaped angle adjustment seat rotatably connected inside the telescopic reinforcing rod. A locking mechanism for limiting the rotation of the H-shaped angle adjustment seat is provided inside the telescopic reinforcing rod. The locking mechanism includes a support ring, a lifting spring, and a triangular limiting block. The support ring is fixedly connected to the outer surface of the telescopic reinforcing rod, the lifting spring is fixedly connected inside the support ring, and the triangular limiting block is slidably connected inside the support ring, with the support ring sleeved on the outer surface of the triangular limiting block. A set of arc-shaped slots is provided inside the H-shaped angle adjustment seat, and the triangular limiting block is locked into the set of arc-shaped slots.

[0012] Preferably, the telescopic reinforcing rod is provided with a strap inside, and the H-shaped angle adjusting seat is provided with a set of internal threaded grooves inside.

[0013] Preferably, the telescopic reinforcing rod and a set of internally threaded through grooves are internally threaded with bolts.

[0014] Preferably, the outer surface of the telescopic reinforcing rod is slidably connected to a support sleeve, and the support sleeve is internally threaded with an externally threaded swivel.

[0015] Preferably, a set of arc-shaped elastic clips are fixedly connected inside the support sleeve.

[0016] Preferably, the external threaded swivel ring has a cylindrical extrusion groove inside.

[0017] Preferably, a set of anti-slip rubber strips are fixedly connected to the outer surface of the external threaded swivel.

[0018] Preferably, the outer surface of the support sleeve is fixedly connected to three rod mounting seats, and each of the three rod mounting seats is rotatably connected to a conical rod.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. To accommodate the growth angle of pear tree branches, the H-shaped angle adjustment seat, which is rotatably connected within the telescopic reinforcing rod, is manually screwed on, causing it to rotate around the connection point. During rotation, the inclined surface of the arc-shaped groove inside the H-shaped angle adjustment seat presses against the triangular limiting block, causing it to compress the lifting spring and slide down. When rotating to the next arc-shaped groove position, the triangular limiting block loses its pressing force and, under the elastic force of the lifting spring, pushes upward and engages with the new groove. Because there are five arc-shaped grooves, the angle adjustment of the H-shaped angle adjustment seat is limited, ensuring it remains stably in the corresponding position during screwing and installation. This stable placement allows workers to easily complete the screwing and installation work with one hand, making the operation more efficient and convenient.

[0021] 2. To adjust the extension length of the telescopic reinforcement rod, unscrew the external threaded swivel to reduce the squeezing force on the arc-shaped elastic clip, and loosen the fixation on the telescopic reinforcement rod. At this point, the extension length of the telescopic reinforcement rod in the support sleeve can be freely adjusted. Under the premise of ensuring stable placement, the extension length can be adjusted conveniently and quickly. Attached Figure Description

[0029] This application provides a foldable pear tree branch support frame, effectively solving the problem that traditional adjustable-angle support frames, designed to accommodate different branch growth angles, typically use bolts to align with two slots and screw them on. However, the lack of elastic locking and limiting function prevents the adjustable seat from being stably supported in the screw-on position when determining the rotation angle. Users must simultaneously support the support to prevent rotational shift while tightening the bolts, a cumbersome and time-consuming process. When multiple support frames need to be installed, the cumulative operation time increases significantly, reducing work efficiency. To accommodate the pear tree branch growth angle, the H-shaped angle adjustment seat, rotatably connected within the telescopic reinforcing rod, is manually screwed on, allowing it to rotate around the connection point. During rotation, the inclined surface of the arc-shaped slot within the H-shaped angle adjustment seat presses against the triangular limiting block, compressing the lifting spring and causing it to slide downwards. When the device rotates to the next arc-shaped slot, the triangular limit block loses its squeezing force and, under the action of the lifting spring, pushes up and engages in the new slot. Because there are five arc-shaped slots, the adjustment angle of the H-shaped angle adjustment seat is limited, allowing it to be stably maintained in the corresponding position during screwing and installation. The stable placement position allows workers to easily complete the screwing and installation work with one hand, making the operation more efficient and convenient.

[0030] Example

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application embodiment effectively solves the problem that, in order to adapt to different branch growth angles, adjustable angle support frames are usually fixed by screwing bolts into two slots. When determining the rotation angle, the lack of elastic locking and limiting function prevents the adjustment seat from being stably supported in the screwing position. Users need to simultaneously support the frame to ensure no rotational deviation while tightening the bolts, a cumbersome process that often takes a considerable amount of time. When multiple support frames need to be installed, the cumulative operation time increases significantly, reducing work efficiency. The overall approach is as follows: A foldable pear tree branch support frame includes a telescopic reinforcing rod 11. An adjustment mechanism for adapting to branch angles is rotatably connected inside the telescopic reinforcing rod 11. The adjustment mechanism includes an H-shaped angle adjustment seat 12, which is rotatably connected inside the telescopic reinforcing rod 11. A locking mechanism for limiting the rotation of the H-shaped angle adjustment seat 12 is provided inside the telescopic reinforcing rod 11. The locking mechanism includes a support ring 13, a lifting spring 14, and a triangular limiting block 15. Ring 13 is fixedly connected to the outer surface of telescopic reinforcing rod 11. Lifting spring 14 is fixedly connected to the inside of support ring 13. Triangular limiting block 15 is slidably connected to the inside of support ring 13. Support ring 13 is sleeved on the outer surface of triangular limiting block 15. H-shaped angle adjusting seat 12 has a set of arc-shaped slots 16 inside. Triangular limiting block 15 is engaged in the set of arc-shaped slots 16. The H-shaped angle adjusting seat 12 can be rotated to adapt to the growth angle of pear tree branches. When adjusting the H-shaped angle adjusting seat 12, manually rotate the H-shaped angle adjusting seat. 12. When the H-shaped angle adjusting seat 12 rotates, it will push the triangular limiting block 15 downward through the inclined surface of the arc-shaped slot 16 inside. The triangular limiting block 15 slides and compresses the lifting spring 14. When the H-shaped angle adjusting seat 12 rotates to the next arc-shaped slot 16 inside, the triangular limiting block 15 loses the squeezing force and is lifted upward by the lifting spring 14 to engage in the arc-shaped slot 16, thereby limiting the adjustable angle of the H-shaped angle adjusting seat 12. Five arc-shaped slots 16 are opened inside the H-shaped angle adjusting seat 12.

[0032] The telescopic reinforcing rod 11 has a strap 17 inside, and the H-shaped angle adjustment seat 12 has a set of internal threaded grooves 18 inside. The telescopic reinforcing rod 11 and the set of internal threaded grooves 18 are connected by bolt rods 27. By screwing the bolt rods 27 into the internal threaded grooves 18 and the internal threaded grooves inside the telescopic reinforcing rod 11, the H-shaped angle adjustment seat 12 is fixedly installed inside the telescopic reinforcing rod 11 to ensure stable support.

[0033] A support sleeve 19 is slidably connected to the outer surface of the telescopic reinforcing rod 11. An externally threaded swivel ring 21 is threadedly connected inside the support sleeve 19, rotatably connected to the outer surface of the telescopic reinforcing rod 11. A set of arc-shaped elastic clips 22 are fixedly connected inside the support sleeve 19, all of which are located on the outer surface of the telescopic reinforcing rod 11. A cylindrical extrusion groove 23 is formed inside the externally threaded swivel ring 21, fitting snugly against the outer surface of the set of arc-shaped elastic clips 22. A set of anti-slip rubber strips 24 are fixedly connected to the outer surface of the externally threaded swivel ring 21. Three insert rod mounting seats 25 are fixedly connected to the outer surface of the support sleeve 19, each rotatably connected to a conical insert rod 26. The extension length of the telescopic reinforcing rod 11 can be adjusted by sliding it within the support sleeve 19. The conical insert 26, which rotates outward from the support sleeve 19 and is located within the insert mounting base 25, can be rotated and folded, thus saving space during transportation. The rotatable conical insert 26 can be inserted into the pear orchard to fix the entire device. When adjusting the telescopic reinforcement rod 11, the external threaded swivel ring 21 is screwed on. The external threaded swivel ring 21 is threaded into the support sleeve 19. When screwed outward, the external threaded swivel ring 21 will rotate upward. The cylindrical extrusion groove 23 inside the external threaded swivel ring 21 extrudes the arc-shaped surface of the arc-shaped elastic clip 22, so that the four elastic arc-shaped elastic clips 22 clamp the surface of the telescopic reinforcement rod 11 to fix the telescopic reinforcement rod 11. After unscrewing the external threaded swivel ring 21, the fixation of the telescopic reinforcement rod 11 is released, and the extension length of the telescopic reinforcement rod 11 can be adjusted.

[0034] To address the problems existing in the prior art, this utility model provides a foldable pear tree branch support frame. To accommodate the growth angle of pear tree branches, the H-shaped angle adjustment seat 12, rotatably connected within the telescopic reinforcing rod 11, is manually screwed on, causing it to rotate around the connection point. During rotation, the inclined surface of the arc-shaped groove 16 within the H-shaped angle adjustment seat 12 presses against the triangular limiting block 15, causing it to compress the lifting spring 14 and slide down. When rotating to the next arc-shaped groove 16 position, the triangular limiting block 15 loses its pressing force and, under the elastic force of the lifting spring 14, pushes upward and engages with the new groove. Because there are five arc-shaped grooves 16, the angle adjustment of the H-shaped angle adjustment seat 12 is limited, ensuring it remains stably in the corresponding screw-on installation position. This stable placement allows workers to easily complete the screw-on installation with one hand, making the operation more efficient and convenient.

[0035] Telescopic reinforcing rod 11: As one of the main structures of the support frame, it is internally rotatably connected to H-shaped angle adjustment seat 12, providing an installation base for the adjustment mechanism and realizing the angle adjustment function;

[0036] H-shaped angle adjustment seat 12: It has a set of arc-shaped slots 16 inside, which cooperate with the triangular limiting block 15 to limit the adjustment angle of itself; In addition, a set of internal thread through slots 18 inside corresponds to the internal thread slots inside the telescopic reinforcement rod 11. By tightening the bolt rod 27, it is fixedly installed inside the telescopic reinforcement rod 11 to ensure the stability of the support.

[0037] Support ring 13: It is sleeved on the outer surface of the triangular limiting block 15 and guides the sliding of the triangular limiting block 15, so that it can only slide in a specific direction inside the support ring 13, ensuring the stable operation of the locking mechanism.

[0038] Lifting spring 14: When the triangular limiting block 15 is pressed by the inclined surface of the arc-shaped groove 16 inside the H-shaped angle adjusting seat 12, the lifting spring 14 is compressed and stores elastic potential energy; when the H-shaped angle adjusting seat 12 rotates to the next arc-shaped groove 16 position, and the triangular limiting block 15 loses the pressing force, the lifting spring 14 releases the elastic potential energy, lifts the triangular limiting block 15 upward, and makes it fit into the new arc-shaped groove 16, thereby limiting the adjustment angle of the H-shaped angle adjusting seat 12.

[0039] Triangular limiting block 15: When the H-shaped angle adjusting seat 12 rotates, the inclined surface of its internal arc-shaped groove 16 presses the triangular limiting block 15, causing it to slide downward within the support ring 13, compressing the lifting spring 14; when the H-shaped angle adjusting seat 12 rotates to the appropriate position, the triangular limiting block 15, which loses the pressing force, is lifted upward by the elastic force of the lifting spring 14 and engages in the corresponding arc-shaped groove 16 within the H-shaped angle adjusting seat 12, limiting the rotation angle of the H-shaped angle adjusting seat 12, so that the support frame can be stably maintained in a position that adapts to the growth angle of the pear tree branches;

[0040] Arc-shaped slot 16: When the H-shaped angle adjustment seat 12 rotates, the inclined surface of the arc-shaped slot 16 presses and pushes the triangular limiting block 15, causing it to slide; when rotated to the appropriate position, the triangular limiting block 15 is engaged in the corresponding arc-shaped slot 16 under the action of the lifting spring 14, fixing the angle of the H-shaped angle adjustment seat 12; since there are five arc-shaped slots 16, multiple adjustable angle positions are provided to meet the needs of different pear tree branches growing at different angles;

[0041] Strap 17: Used to bind the pear tree branch to the H-shaped angle adjustment seat 12 for fixation. It contains a spring buckle that can be pressed open to adjust the opening degree.

[0042] Internal thread through groove 18: By threading the bolt rod 27 into these two internal thread structures, the H-shaped angle adjustment seat 12 is firmly fixed inside the telescopic reinforcement rod 11, ensuring that the angle adjustment part can provide stable support when the support frame supports the pear tree branches;

[0043] Bolt rod 27: The H-shaped angle adjustment seat 12 is fixedly installed inside the telescopic reinforcement rod 11 so that the two form a stable whole, ensuring that the support frame can stably support the pear tree branches after the angle is adjusted;

[0044] Support sleeve 19: Its outer surface is slidably connected to the telescopic reinforcing rod 11, providing a sliding track for the telescopic reinforcing rod 11 to realize the adjustment of the extension length of the support frame;

[0045] External thread swivel 21: When the external thread swivel 21 is screwed, due to its threaded connection with the support sleeve 19, it will screw upwards when screwed outwards. The cylindrical extrusion groove 23 inside it extrudes the arc-shaped surface of the arc elastic clip 22, thereby fixing or loosening the telescopic reinforcing rod 11 to adjust the extension length of the telescopic reinforcing rod 11.

[0046] Arc-shaped elastic clip 22: Made of spring sheet material, when the arc-shaped surface of the arc-shaped elastic clip 22 is squeezed by the cylindrical extrusion groove 23 inside the external threaded swivel ring 21, the arc-shaped elastic clip 22 is clamped on the surface of the telescopic reinforcing rod 11 to fix the telescopic reinforcing rod 11. When the external threaded swivel ring 21 is unscrewed to reduce the extrusion force on the arc-shaped elastic clip 22, the fixation on the telescopic reinforcing rod 11 is released, making it easy to adjust the extension length of the telescopic reinforcing rod 11 in the support sleeve 19.

[0047] Cylindrical extrusion groove 23: When the external threaded swivel ring 21 is unscrewed, the cylindrical extrusion groove 23 moves with the external threaded swivel ring 21 and extrudes the arc-shaped surface of the arc-shaped elastic clamp 22, causing the arc-shaped elastic clamp 22 to deform and clamp onto the surface of the telescopic reinforcing rod 11, thereby fixing the telescopic reinforcing rod 11.

[0048] Anti-slip rubber strip 24: Increases the friction between the operator's hand and the external threaded swivel ring 21 when the operator is turning the external threaded swivel ring 21, making the turning operation more effortless and convenient, and avoiding operation difficulties caused by slipping hands;

[0049] Insert rod mounting base 25: Provides a fulcrum for the installation and rotation of the conical insert rod 26, allowing the conical insert rod 26 to be rotated and folded within the insert rod mounting base 25 for easy transportation. When in use, the conical insert rod 26 can be rotated out and inserted into the ground of the pear orchard to fix the entire support frame device.

[0050] Conical insert 26: It can be rotated and folded during transportation to save space. When in use, it is rotated out from the insert mounting base 25 and inserted into the ground of the pear orchard to fix the entire support frame device and ensure the stability of the support frame when supporting pear tree branches.

[0051] Working principle:

[0052] The first step involves threading the bolt rod 27 into the internal threaded groove inside the telescopic reinforcing rod 11 and the internal threaded through groove 18 inside the H-shaped angle adjusting seat 12. This securely fixes the H-shaped angle adjusting seat 12 inside the telescopic reinforcing rod 11, ensuring stable support for the angle adjustment section when supporting pear tree branches. The telescopic reinforcing rod 11 can slide within the support sleeve 19 to adjust the extension length of the support frame. The support sleeve 19 has an external threaded swivel ring 21 threadedly connected to its interior. The external threaded swivel ring 21 is rotatably connected to the outer surface of the telescopic reinforcing rod 11, and a set of anti-slip rubber strips 24 are fixedly connected to its outer surface for easy tightening. When the position of the telescopic reinforcing rod 11 needs to be fixed, the external threaded swivel ring 21 is tightened. Since the external threaded swivel ring 21 and the support sleeve 19 are threadedly connected, when tightened outwards, the external threaded swivel ring 21 will rotate upwards. The cylindrical extrusion groove 23 inside the external threaded swivel ring 21 will engage with the arc-shaped elastic clamp. The curved surface of the plate 22 is compressed, and the curved elastic clamp 22 is fixed inside the support sleeve 19 and set on the outer surface of the telescopic reinforcing rod 11. It is elastic and will clamp on the surface of the telescopic reinforcing rod 11 after being compressed, thereby fixing the telescopic reinforcing rod 11. If the extension length of the telescopic reinforcing rod 11 is to be adjusted, the external threaded swivel ring 21 is unscrewed to reduce the compressive force on the curved elastic clamp 22 and loosen the fixation on the telescopic reinforcing rod 11. At this time, the extension length of the telescopic reinforcing rod 11 in the support sleeve 19 can be freely adjusted. Three rod mounting seats 25 are fixedly connected to the outer surface of the support sleeve 19. The conical rod 26 is rotatably connected inside the rod mounting seat 25 and can be rotated and folded. During transportation, the conical rod 26 can be rotated and folded to save space. When in use, the rotatable conical rod 26 is inserted into the ground of the pear orchard to fix the entire support frame device and ensure its stability when supporting pear tree branches.

[0053] The second step, to accommodate the growth angle of the pear tree branches, involves operating the H-shaped angle adjustment seat 12 in the adjustment mechanism. The H-shaped angle adjustment seat 12 is rotatably connected inside the telescopic reinforcing rod 11. When manually turned, the H-shaped angle adjustment seat 12 rotates around its connection point with the telescopic reinforcing rod 11. The H-shaped angle adjustment seat 12 has a set of arc-shaped slots 16 inside. When the H-shaped angle adjustment seat 12 rotates, the inclined surface of the arc-shaped slots 16 inside will press and push the triangular limiting block 15. The triangular limiting block 15, after being pressed, will compress and rise. Spring 14 slides downwards. When the H-shaped angle adjustment seat 12 rotates to the position of the next arc-shaped slot 16 opened inside, the triangular limiting block 15 loses the squeezing force from the inclined surface of the arc-shaped slot 16. At this time, under the upward elastic force of the lifting spring 14, the triangular limiting block 15 is lifted upwards and locked in the new arc-shaped slot 16. Since five arc-shaped slots 16 are opened inside the H-shaped angle adjustment seat 12, the adjustable angle of the H-shaped angle adjustment seat 12 is limited in this way, so that it is aligned to the position required for screwing installation.

[0054] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
