Description

Technical Field

[0001] This utility model relates to the field of buckle technology, specifically to a buckle for telescopic rods. Background Technology

[0002] Telescopic pruning shears are a specialized gardening tool for pruning fruit tree branches. Their main feature is the telescopic handle, allowing for length adjustment to suit different needs. These shears typically use high-strength stainless steel blades, making them sharp and durable, easily cutting branches of varying thicknesses. Their telescopic design allows users to prune from different heights and positions without frequent tool changes or climbing, improving efficiency and reducing safety risks associated with climbing. Widely applicable in orchards and gardens, they are an invaluable tool for fruit growers and gardening enthusiasts.

[0003] In the telescopic control structure of telescopic fruit shears, bolts are a common fixing method. However, this design has certain drawbacks. In actual use, the fruit shears frequently move in and out of orchards and other environments, and the bolt holes easily accumulate dust, debris, and various types of dirt. Over time, this affects the smooth tightening of the bolts. Moreover, under repeated telescopic and fixing operations, the area around the bolt holes is subjected to significant stress, making it prone to wear and even breakage, thus reducing the overall service life and stability of the fruit shears. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a convenient and practical telescopic rod buckle that can quickly lock the telescopic rod, is not easily damaged, and has a good locking effect.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a buckle for a telescopic rod, comprising:

[0006] The pipe body includes a bottom pipe and a fastening pipe. The fastening pipe is integrally formed on the upper end of the bottom pipe, and an arc-shaped gap is formed between its bottom surface and the top surface of the bottom pipe. The inner diameter of the fastening pipe is smaller than the inner diameter of the bottom pipe, and a shrinkage gap is provided on one side of the fastening pipe.

[0007] The locking mechanism includes a locking block, a locking handle, and a bolt. Two locking blocks are integrally formed and located on both sides of the contraction gap on the side wall of the fastening tube. One end of the locking handle is provided with a U-shaped groove that matches the locking block, and the locking block is located in the U-shaped groove. The bolt passes through both the locking handle and the locking block, with its head embedded in the side wall of the locking handle, and the other end is threaded with a nut.

[0008] Furthermore, anti-slip grooves are provided on the outer walls of both the bottom tube and the fastening tube.

[0009] Furthermore, the shrinkage gap is located above the middle of the arc-shaped gap, with the upper end of the shrinkage gap extending to the top of the fastening tube and the lower end communicating with the arc-shaped gap.

[0010] Furthermore, the locking handle has several anti-slip protrusions on the side wall away from the locking block.

[0011] Furthermore, the bolt head is hexagonal, and the locking handle has a hexagonal groove on its side wall that matches the bolt head.

[0012] Furthermore, the nut is a wing nut.

[0013] Compared with existing technologies, the advantages of this invention are as follows: the design of anti-slip grooves and anti-slip protrusions increases the friction with the hand, making the grip more stable and the operation easier. A contraction gap is provided on one side of the fastening tube, which connects with the arc-shaped gap, allowing for more even contraction under force, enabling quick fastening of the telescopic rod. Furthermore, the bolt and wing nut structure allows for tool-free locking, greatly improving installation and disassembly efficiency.

[0014] The pipe body utilizes a one-piece molded base pipe and fastening pipe, resulting in high structural strength and reducing the risk of damage due to loose connections. In the locking mechanism, the bolt head and locking handle are fixed together via a hexagonal structure, preventing damage caused by bolt loosening and displacement, thus enhancing overall durability. These design features collectively ensure the excellent performance of the latch. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings.

[0021] Combined with appendix Figure 1 Appendix Figure 3A buckle for a telescopic pole includes: a tube body comprising a base tube 1 and a fastening tube 2, wherein both the base tube 1 and the fastening tube 2 have anti-slip grooves 9 on their outer walls to increase friction when in contact with the hand. When operating the telescopic pole buckle, the user can grip it more securely, avoiding slippage and improving ease of use and safety.

[0022] Combined with appendix Figure 1 Appendix Figure 2 The fastening tube 2 is integrally formed on the upper end of the bottom tube 1, and an arc-shaped gap 3 is formed between its bottom surface and the top surface of the bottom tube 1. The inner diameter of the fastening tube 2 is smaller than the inner diameter of the bottom tube 1. A shrinkage gap 4 is provided on one side of the fastening tube 2. The shrinkage gap 4 is located above the middle of the arc-shaped gap 3. The upper end of the shrinkage gap 4 extends to the top of the fastening tube 2, and the lower end communicates with the arc-shaped gap 3, so that the fastening tube 2 can shrink more evenly when subjected to force, which enhances the fastening effect on the telescopic rod and ensures that the buckle plays a better role.

[0023] Combined with appendix Figure 1 Appendix Figure 2 The locking mechanism includes a locking block 5, a locking handle 6, and a bolt 7. The locking block 5 is provided in two parts and is integrally formed on both sides of the contraction gap 4 on the side wall of the fastening tube 2. One end of the locking handle 6 is provided with a U-shaped groove that matches the locking block 5. The locking block 5 is located in the U-shaped groove. The side wall of the locking handle 6 away from the locking block 5 is provided with several anti-slip protrusions 10, which can increase the friction between the hand and the locking handle 6, allowing the user to hold the handle more easily and stably, and making it convenient to perform locking or unlocking operations.

[0024] Combined with appendix Figure 1 Appendix Figure 3 Appendix Figure 4 The bolt 7 passes through both the locking handle 6 and the locking block 5, with its head embedded in the side wall of the locking handle 6. The other end is threaded with a nut 8. The bolt 7 has a hexagonal head, and the side wall of the locking handle 6 has a matching hexagonal groove to secure the bolt 7 to the locking handle 6. Fixing the locking handle 6 secures the bolt 7, facilitating the tightening and loosening of the nut 8. The operation is convenient and effortless. The nut 8 is a wing nut, requiring no tools; the user can tighten or loosen it directly by hand, simplifying the operation, saving time and effort, and improving the efficiency of installing and disassembling the telescopic rod clip.

[0025] The specific implementation method of this utility model is as follows: First, the bottom tube 1 of the tube body is installed and fixed to the fixing part of the telescopic rod extension and contraction, and the fastening tube 2 is located at the extension and contraction part of the telescopic rod extension and contraction. When the telescopic rod extends to a suitable length, the tube body is gripped and locked. The anti-slip groove 9 on the outer wall of the bottom tube 1 and the fastening tube 2 can provide good friction to ensure stable grip.

[0026] The rotating nut 8 is in close contact with the side wall of the locking handle 6 and continues to approach the head of the bolt 7. Since the head of the bolt 7 is hexagonal and matches the hexagonal recess on the side wall of the locking handle 6, the bolt 7 is relatively fixed with the locking handle 6. When the nut 8 rotates, if the bolt 7 rotates with it, the locking handle 6 will rotate with the bolt 7 and be lifted. At this time, only need to press the locking handle 6 downward, the bolt 7 can be fixed, and the nut can be rotated smoothly. The nut 8 drives the two locking blocks 5 to approach each other, the gap 4 is reduced, so that the inner wall of the fastening pipe 2 approaches the outer wall of the telescopic rod telescopic part, until it is tightly attached to the telescopic rod telescopic part to fix it, and the locking is completed.

[0027] When the telescopic rod needs to be moved, the butterfly nut 8 is rotated in the opposite direction, so that the fastening pipe 2 returns to its original state, and the telescopic rod can be easily moved. The whole process is simple and convenient.
