Description

Technical Field

[0001] This utility model relates to the field of electronic fence technology, specifically a rainproof electronic fence handle. Background Technology

[0002] With the rapid development of livestock farming towards large-scale and intensive operations, the scale of farming is constantly expanding, placing higher demands on the scientific management and safety protection of livestock. As a core facility for demarcating farming areas, preventing livestock from wandering off, and resisting predator intrusion, the performance of fencing directly affects farming efficiency and safe production. While traditional solid fencing can achieve basic isolation functions, it is no longer sufficient to meet the needs of modern farming in terms of flexibility in range adjustment and intelligent management. Therefore, pulse-type and wireless electronic fencing are gradually becoming mainstream, providing more efficient technical support for large-scale farming through precise range control and real-time boundary monitoring. These electronic fences typically consist of fixed poles, fencing mesh, and connecting components. Among these, the connecting components are crucial for ensuring a stable connection between the fencing mesh and the fixed poles, guaranteeing structural strength to maintain the overall shape of the fence.

[0003] In outdoor farming environments, electronic fences are constantly exposed to natural conditions such as rain, snow, and humidity, posing a severe challenge to the durability of their connecting components. Existing connecting components mostly use traditional bolts, clips, and simple spring connections. The springs, exposed for extended periods, lack specialized rainproof structures, leading to rust from rainwater, reduced mechanical connection strength, and increased susceptibility to breakage of springs and clips. This compromises the fence's overall strength and reduces its protective effect on livestock. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a rainproof electronic fence handle.

[0005] The technical solution of this utility model is as follows: A rainproof electronic fence handle that can fix the fence net to the fence post, including a handle that is hollow and open at both ends of a cylindrical shape; The two ends of the grip are fitted with sealing plates, and the two sealing plates are fixed together by fasteners; The handle is equipped with a tension spring located near the upper end of the handle. The upper end of the tension spring has a hook that penetrates the upper sealing plate and can be hooked to the fence post. The bottom end of the hook is fixed to the inner and outer end faces of the sealing plate. The lower end of the tension spring has a hanging ring that penetrates the lower sealing plate and is used to fix the fence netting.

[0006] To facilitate the installation of the sealing plate, the two ends of the handle are provided with stepped openings to form receiving grooves for placing the sealing plate.

[0007] To further ensure the stability of the sealing plate, a limit block is integrally formed with the opening edge of the grip facing its axis, and a corresponding limit slot is opened on the sealing plate.

[0008] The fastener is specifically designed as follows: the fastener includes multiple connecting rods disposed in the grip area, and the two ends of the connecting rods pass through two sealing plates. The connecting rod located outside the sealing plate is stamped with a first protrusion, which extends in a direction away from the center of the connecting rod and abuts against the sealing plate.

[0009] To ensure the sealing plate is fixed stably and to facilitate the arrangement of connecting rods, two connecting rods are provided, and they are arranged symmetrically with respect to the axis of the grip.

[0010] To facilitate the fixing of the hook and ring parts to the tension spring, the tension spring includes a main body, and the two ends of the main body are integrally formed with mounting parts. The outer diameter of the mounting parts is smaller than the outer diameter of the main body, and the hook and ring parts are respectively inserted into the two mounting parts for fixing.

[0011] The hook and the ring are fixed in such a way that the bottom end of the hook and the top end of the ring are both provided with external threads, and the external threads can be screwed into the mounting part to form mutual limiting between them and the spiral coil of the tension spring.

[0012] To facilitate fixing the hook and allow the lifting ring to adjust its position by pulling the tension spring, the outer end faces of the hook rods inside and outside the sealing plate are all stamped with a second protrusion, which abuts against the sealing plate.

[0013] To prevent over-adjustment when adjusting the position of the hook, a third protrusion is stamped on the hook rod portion located inside the grip, extending away from its axis.

[0014] In order to provide protection for the hand when the grip is adjusted, both ends of the grip are formed with frustum-shaped protective parts, and the protective parts are hollow, with the length of the bottom edge away from the grip being greater than the length of the bottom edge connected to the grip.

[0015] The beneficial effects of this utility model are as follows: This utility model is a rainproof electronic fence handle. A closed cavity is formed by the hollow cylindrical handle and the end sealing plates, which, together with the frustum-shaped protective part, constitute a stepped rainproof barrier. The stepped receiving grooves and limiting blocks of the sealing plates and handle significantly enhance the sealing performance at the connection, effectively preventing rainwater intrusion and solving the corrosion problem caused by exposure of existing spring connections. This improves the weather resistance of core components such as the tension spring, ensuring stable mechanical elasticity during long-term use. Simultaneously, the tension spring is axially fixed through the threaded engagement of the mounting part with the hook and lifting ring, and the limiting of the spiral coil. Two symmetrical connecting rods penetrate the sealing plate and are locked by stamped protrusions. With the radial constraint of the limiting blocks, the structure's impact resistance is greatly improved, effectively preventing component breakage and ensuring the connection strength between the fence net and the fence rod, as well as the reliable enclosure effect for livestock. The limiting slot and receiving slot design of the handle and the sealing plate enables quick positioning and installation, reducing assembly errors. The threaded connection of the hook, lifting ring and tension spring and the detachable structure of the sealing plate facilitate the individual replacement of damaged parts, reducing maintenance costs. The stamped protrusion fixing method of the connecting rod can also avoid the corrosion and jamming problems of traditional bolts. The overall lightweight design and symmetrical layout ensure balanced force distribution and can be adapted to various electronic fences such as pulse type and wireless type, improving its applicability in large-scale breeding scenarios.

[0018] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0019] Example As mentioned in the background section, electronic fences are commonly used in livestock farming. They form a farming space by fixing the fence netting and fence posts. The two are usually connected by simple springs, buckles, or other simple means. However, when used outdoors, the springs are easily corroded by rainwater and can corrode over time, causing the spring force to decrease or even break, thus failing to perform the fixing function. Therefore, the inventor has combined the existing fixing methods to make improvements and designed a new type of electronic fence handle for fixing the fence netting and fence posts. The following is a detailed explanation with reference to the illustrations.

[0020] This embodiment provides a rainproof electronic fence handle; see [link / reference] Figure 1 Specifically designed to address the problem of traditional fence connection components being easily eroded by rainwater and having reduced structural strength in outdoor aquaculture environments, this product achieves a long-term stable connection between the fence net and the fence pole through an integrated rainproof structure and reinforced fixing method. Its specific structure and working principle are as follows.

[0021] In this embodiment, the handle includes a grip portion 1, combined with... Figure 1 and Figure 2 As the main support of the entire handle, it adopts a hollow cylindrical design, with open ends and a completely open interior. The cylinder wall is made of high-strength engineering plastic, which not only has excellent UV resistance, resisting aging caused by long-term outdoor sunlight, but also adapts to significant temperature changes. Sealing plates 2 are installed at both ends of the grip 1, and the two sealing plates 2 are fixed together by fasteners. It should be noted that, to achieve a tight fit with the sealing plates 2, the openings at both ends of the grip 1 are specially designed with a stepped structure. Figure 3 and Figure 5 This forms an inwardly recessed receiving groove 6, the depth of which matches the thickness of the sealing plate 2, ensuring that the sealing plate 2 remains flush with the edge of the opening after being embedded, thus preventing the formation of water accumulation gaps. Simultaneously, combined with... Figure 4 and Figure 5 The opening edge is integrally formed with symmetrically distributed limiting blocks 7 along the radial direction to the axis. Correspondingly, the edge of the sealing plate 2 is provided with a limiting groove 8 that matches the shape of the blocks. During assembly, the precise engagement of the blocks and grooves can effectively limit the circumferential rotation of the sealing plate 2, preventing it from shifting position due to vibration or force during use, thereby ensuring the durability of the sealing effect.

[0022] In this design, the fixing component includes multiple connecting rods 9 installed inside the grip 1. There are two connecting rods arranged symmetrically with respect to the axis of the grip 1, and the two ends of the connecting rods 9 pass through the two sealing plates 2. The portions of the connecting rods 9 extending beyond the sealing plates 2 are stamped to form outwardly opening first protrusions 10. These protrusions are flat and turn outward away from the center of the connecting rod, tightly abutting against the outer end face of the sealing plate 2. Through the opposing force formed by the protrusions on both sides, the two sealing plates 2 are firmly pressed into the receiving groove 6, which can effectively prevent rainwater from seeping into the interior from the gaps at the ends.

[0023] Based on the above structure, a tension spring 3 is installed inside the handle 1 near the upper end. The tension spring 3 is made of high-quality steel and galvanized, providing strong corrosion resistance and reducing corrosion caused by direct contact with rainwater. The main body 31 of the tension spring 3 maintains a relatively large diameter, while both ends are integrally formed into mounting parts 32 with a reduced diameter, creating a natural stepped transition. This design ensures the elastic tension of the main body 31 and provides a suitable interface for connection with the hook part 4 and the hanging ring part 5. The mounting part 32 at the upper end of the tension spring 3 is connected to the hook part 4. The hook part 4 is generally "J" shaped, with the end of the horizontal section bent to form a hook structure. Its opening size is adapted to the size of the fixing ring on common fence posts. After the vertical section of the rod passes through the center hole of the upper sealing plate 2, the bottom end is fixed to the tension spring 3 through a special connection method. Specifically, the outer surface of the bottom end of the rod is machined with a threaded structure. After being screwed into the mounting part 32 at the upper end of the tension spring 3, the thread can engage with the spiral coil of the tension spring 3 to form a reliable mechanical limit, effectively preventing it from falling off during use.

[0024] Similarly, the mounting part 32 at the lower end of the tension spring 3 is connected to the lifting ring part 5. The lifting ring part 5 adopts a closed ring structure, and the size of the ring is suitable for threading the edge rope of the fence net. The top of its vertical rod is also threaded and screwed into the mounting part 32 at the lower end of the tension spring 3. To further enhance the installation stability of the hook part 4 and the lifting ring part 5, the outer end face of the hook part 4 rod part inside and outside the sealing plate 2 is stamped with a second protrusion 11, which is set against the sealing plate 2. The protrusion located on the inner side is inside the grip part 1 and is tightly abutted against the inner end face of the sealing plate 2. The protrusion located on the outer side is in contact with the outer end face of the sealing plate 2. Through the limiting effect of the bidirectional protrusion, the axial movement of the hook part 4 caused by the extension and retraction of the tension spring 3 can be effectively prevented, ensuring the stability of the connection. In addition, the hook part 4 inside the handle part 1 is stamped with a third protrusion 12 extending outward. These protrusions extend away from the axis of the rod. When the tension spring 3 is stretched, the lifting ring part 5 moves outward. When the third protrusion 12 moves to abut against the sealing plate 2, it can limit its continued movement. This can effectively reduce the excessive stretching of the tension spring 3 and the resulting large deformation, thereby extending its service life.

[0025] Based on the above structure, both ends of the grip 1 are integrally formed with frustum-shaped protective parts 13. The protective parts 13 also adopt a hollow structure and are completely connected to the interior of the grip 1. The diameter of the end away from the grip 1 is larger than the diameter of the end connected to the grip 1, forming an outward-opening trumpet shape. This inclined slope design can guide rainwater to slide outward, avoiding rainwater directly impacting the connection between the sealing plate 2 and the connecting rod. At the same time, the length of the protective parts 13 is sufficient to cover the edge of the sealing plate 2, forming the first rainproof barrier. It works in conjunction with the sealing structure of the internal sealing plate 2 to form a double protection system, and can also provide a certain degree of protection for the hands of the staff when holding the grip 1.

[0026] During the assembly process, firstly, the lifting ring 5 is screwed into the bottom end of the tension spring 3, and the third protrusion 12 is stamped. The hook part 4 passes through the sealing plate 2 and is screwed into the upper end of the tension spring 3, and the second protrusion 11 is stamped out. The whole is placed into the handle part 1. The lower end of the lifting ring 5 passes through another sealing plate 2. Then, the lifting ring 5 is bent out to form a lifting ring, and the hook part 4 is bent out to form a hook. Finally, the connecting rod 9 passes through the two sealing plates 2 and the first protrusion 10 is stamped out to complete the overall assembly.
