Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit tree support technology, and in particular to a telescopic hook device for citrus fruit-bearing branches. Background Technology
[0002] Citrus trees are an important economic crop, belonging to the Rutaceae family and the Citrus genus. They include various fruits such as oranges, tangerines, pomelos, oranges, kumquats, and lemons. During the growth of citrus trees, as the fruit gradually ripens, the branches may bear a large weight, making them prone to drooping and breaking. Wooden sticks are usually used to support the branches of the fruit trees. The main purpose is to prevent the branches from bending or breaking due to excessive fruit weight. At the same time, it also helps to improve ventilation and light penetration in the canopy, reduce the occurrence of pests and diseases, and promote uniform coloring and ripening of the fruit.
[0003] Existing fruit-supporting devices, when used in practice, require a significant amount of time to find and assemble the supporting sticks when setting up multiple sets of branches for support, resulting in low work efficiency. Furthermore, they struggle to provide support sticks of suitable height for citrus branches of varying growth heights, leading to some branches not receiving effective support and reducing the device's fruit-supporting effect. Therefore, a citrus fruit-bearing branch telescopic hook device is proposed to address these issues. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a telescopic hook device for citrus fruit-bearing branches, which aims to improve the problem that the existing fruit-supporting devices are difficult to adapt to citrus fruit tree branches of different growth heights.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a telescopic hook device for citrus fruit-bearing branches, comprising a telescopic support rod, a triangular bracket fixedly connected to the top of the telescopic support rod, a hollow ring fixedly connected to the upper end of the triangular bracket, a fixed plate fixedly connected inside the hollow ring, a rotating shaft rotatably connected to the outer wall surface of the fixed plate, a take-up roller fixedly connected to the end of the rotating shaft away from the fixed plate, a pull rope fixedly connected to the outer side of the take-up roller, and a hook fixedly connected to the end of the pull rope away from the take-up roller.
[0006] As a further description of the above technical solution:
[0007] A coil spring is provided on the outer side of the rotating shaft, and the outer wall of the coil spring does not fit against the outer wall of the fixing plate and the rotating shaft.
[0008] As a further description of the above technical solution:
[0009] The end of the pull rope furthest from the take-up roller is wrapped around the outside of the take-up roller.
[0010] As a further description of the above technical solution:
[0011] The end of the pull rope away from the take-up roller passes through the hollow ring.
[0012] As a further description of the above technical solution:
[0013] A sponge plug is fixedly connected inside the connection between the hollow ring and the pull rope, and the sponge plug is sleeved on the outside of the pull rope.
[0014] As a further description of the above technical solution:
[0015] The bottom end of the retractable support rod is designed with a pointed shape.
[0016] As a further description of the above technical solution:
[0017] One end of the coil spring is fixedly connected to the outer wall of the rotating shaft, and the other end of the coil spring is fixedly connected to the outer wall of the fixing plate through a connecting rod.
[0018] As a further description of the above technical solution:
[0019] The hollow ring has a hollow structure at its center.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this utility model, the combination of a telescopic support rod, a triangular bracket, a hollow ring, a fixing plate, a rotating shaft, a winding roller, a pull rope, and a hook can quickly limit and support the branches of citrus trees, preventing the branches from drooping or breaking due to the weight of the fruit. The overall height of the device can be adjusted according to the height of the fruit tree. At the same time, the triangular bracket and the hollow structure at the center of the hollow ring minimize the obstruction of sunlight to the fruit tree.
[0022] 2. In this utility model, the coil spring allows the pull rope to quickly return to its original position and wind around the outside of the take-up roller for storage after the hook is removed, thus preventing the pull rope from scattering and becoming tangled during storage. The sponge plug allows the surface of the pull rope to be wiped when the pull rope and hook return to the hollow ring, preventing impurities from adhering to the surface of the pull rope and causing serious wear during winding and rewinding, which would affect the service life of the device.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1-2 This utility model provides an embodiment of a citrus fruit-bearing branch telescopic hook device, including a telescopic support rod 1. The telescopic support rod 1 is composed of multiple support rods vertically threaded together, and the connection between every two adjacent support rods is fixed by bolts. The overall length of the telescopic support rod 1 can be adjusted by rotating the support rod. After adjustment, the bolts can be tightened to fix it, ensuring the stability of the telescopic support rod 1 during use. It can also be disassembled and transported for easy storage. The bottom end of the telescopic support rod 1 is set with a pointed structure. The pointed structure allows the telescopic support rod 1 to be quickly inserted into the soil for fixation. A triangular bracket 2 is fixedly connected to the top end of the telescopic support rod 1. A hollow ring 3 is fixedly connected to the upper end of the triangular bracket 2. The center of the hollow ring 3 is set with a hollow structure. Through the setting of the triangular bracket 2 and the hollow structure at the center of the hollow ring 3, the shading of the fruit tree's sunlight is minimized, thereby reducing the impact on the fruit tree's growth.
[0032] Reference Figures 2-4A fixed plate 4 is fixedly connected inside the hollow ring 3. A rotating shaft 5 is rotatably connected to the outer wall surface of the fixed plate 4. A take-up roller 6 is fixedly connected to the end of the rotating shaft 5 away from the fixed plate 4. The take-up roller 6 can rotate around the fixed plate 4 through the rotating shaft 5. There are several fixed plates 4, rotating shafts 5 and take-up rollers 6, and they are arranged in a ring array inside the hollow ring 3. A pull rope 7 is fixedly connected to the outside of the take-up roller 6. The end of the pull rope 7 away from the take-up roller 6 is wrapped around the outside of the take-up roller 6. The end of the pull rope 7 away from the take-up roller 6 passes through the hollow ring 3. When the pull rope 7 is pulled, it can drive the take-up roller 6 to rotate. A hook 8 is fixedly connected to the end of the pull rope 7 away from the take-up roller 6.
[0033] After adjusting the telescopic support rod 1 and inserting it into the soil for fixation, pull down the rope 7 to move the hook 8 downwards. Then, hang the branch of the fruit tree on the hook 8 to suspend and support the branch, preventing it from drooping or breaking due to the weight of the fruit. At the same time, the branch is engaged with the hook 8 to prevent the hook 8 from moving on the branch and affecting the support effect.
[0034] Reference Figure 1 and Figure 5 A coil spring 9 is provided on the outer side of the rotating shaft 5. One end of the coil spring 9 is fixedly connected to the outer wall of the rotating shaft 5, and the other end of the coil spring 9 is fixedly connected to the outer wall of the fixing plate 4 through a connecting rod. When the pull rope 7 is pulled, causing the take-up roller 6 and the rotating shaft 5 to rotate, the coil spring 9 can be wound up to generate elastic potential energy. After the support of the citrus fruit tree branches is completed, when the hook 8 is removed, the pull on the coil spring 9 will be released simultaneously, allowing the coil spring 9 to reset under its own elastic potential energy. At the same time, it will drive the take-up roller 6 to rotate and reset, so that the pull rope 7 is rewound around the outer side of the take-up roller 6, which facilitates the storage of the pull rope 7 and the hook 8 and avoids multiple pull ropes 7 and hooks 8 in the device. If the coil spring 9 becomes tangled or knotted during placement, it will affect the subsequent use of the device. The outer wall of the coil spring 9 does not fit against the outer walls of the fixed plate 4 and the rotating shaft 5, which can prevent the coil spring 9 from contacting and wearing with the fixed plate 4 and the rotating shaft 5 during movement, thus affecting the service life of the coil spring 9. A sponge plug 10 is fixedly connected inside the connection between the hollow ring 3 and the pull rope 7. The sponge plug 10 is sleeved on the outside of the pull rope 7. When the pull rope 7 is reset and wound around the outside of the take-up roller 6, the sponge plug 10 can wipe and clean the outside of the pull rope 7, preventing impurities from adhering to the surface of the pull rope 7 and causing friction between the pull rope 7 and the pull rope 7 during winding and taking-up, thus affecting the service life of the pull rope 7.
[0035] Working principle: After adjusting and fixing the length of the telescopic support rod 1 by twisting the various support rods on the telescopic support rod 1, insert the telescopic support rod 1 into the soil near the fruit tree, so that the hollow ring 3 is directly above the fruit tree, and fix the whole device. Then, pull the rope 7 downward, so that the hook 8 descends and hangs the branch of the citrus tree on the hook 8 for fixation. This can support the fruit tree branches and prevent sagging or breakage caused by excessive fruit weight. During the process of pulling the rope 7, the winding roller 6 will rotate accordingly, and the coil spring 9 will coil to generate elastic potential energy. When the support work is completed, when the hook 8 is removed, the coil spring 9 will drive the winding roller 6 to rotate and reset under the action of its elastic potential energy, so that the rope 7 can be rewound and stored on the outside of the winding roller 6, avoiding scattering and tangling. At the same time, during the reset process of the rope 7, the sponge plug 10 will clean its surface to prevent impurities from adhering, thereby avoiding serious wear during winding and storage, and ensuring the service life of the device.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
