Description

Technical Field

[0001] This utility model belongs to the field of walking sticks, and in particular relates to a walking stick tip structure that is easy to assemble and disassemble. Background Technology

[0002] The tip system of trekking poles is generally not detachable, and trekking poles usually cannot be taken directly on airplanes and must be checked in. Furthermore, because the tips are not detachable, they cannot be quickly replaced after wear and tear, hindering rapid repairs. For example, Chinese Patent Publication No. CN214509856U discloses a tip structure for dry-land skiing poles. Although this disclosed technical solution allows for tip detachment, it only considers dry-land use and cannot meet the needs of use on land, mud, or snow where mud rails or snow guards are required. Therefore, it significantly affects the ease of tip detachment and installation. Utility Model Content

[0003] This invention provides a cane tip structure that is easy to assemble and disassemble, effectively ensuring the convenience of cane tip assembly and disassembly and improving the efficiency of cane tip assembly and disassembly.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A trekking pole tip structure that is easy to assemble and disassemble includes a pole tube and a tip seat located at the bottom of the pole tube. The tip seat has a pole tip at its bottom. A connector is provided between the pole tube and the tip seat. The connector has a fixing part near the pole tube for fixing to the pole tube. The tip seat has a connecting hole that slides with the connector. A locking nut is fitted onto the bottom of the pole tube. The pole tube and the tip seat are fixed together by the locking nut and the tip seat being threaded together. Thus, the locking nut is located at the bottom of the pole tube and connected to the tip seat by threads. Tightening or loosening the locking nut allows for the fixing or detachment of the tip seat from the pole tube, enabling convenient and quick installation and removal of the tip seat and tip together. Because the locking nut is located on one side of the pole tube, tightening or loosening the tip seat will not interfere with components such as mudguards or snow rails on the tip seat, eliminating the need to disassemble these components first. This effectively reduces the difficulty of disassembly and improves the efficiency and convenience of assembly and disassembly.

[0006] Preferably, the connector is provided with a positioning part for circumferential positioning of the cane tip seat. One of the positioning part and the cane tip seat has at least one positioning key, and the other has a sliding groove adapted to the positioning key. The positioning key and sliding groove work together to provide sliding guidance during cane tip seat installation, ensuring proper placement, and the keyway prevents rotation of the cane tip seat, facilitating a stable and reliable fixing and disassembly process by rotating the locking nut.

[0007] Preferably, the positioning keys are evenly distributed on the positioning part or the cane tip seat. This ensures that the force between the cane tip seat and the connector is more even in the direction of mutual rotation, which helps to ensure the connection strength between the two.

[0008] Preferably, the inner end of the locking nut away from the cane tip seat has an inwardly protruding positioning protrusion, and the connecting piece has a flange with a diameter larger than the inner diameter of the positioning protrusion. After the locking nut is tightened, the positioning protrusion and the flange abut axially. When the locking nut slides to the bottom of the cane tube, the positioning protrusion abuts against the flange, preventing the locking nut from coming off the cane tube, thus avoiding loss of the locking nut and ensuring the integrity of the cane tube and cane tip seat when transported and stored separately.

[0009] Preferably, the locking nut has an internal thread in its inner hole, and the cane tip seat has an external thread that mates with the internal thread. The locking nut's inner hole also has a groove between the internal thread and the positioning protrusion that matches the width of the flange. Thus, when the locking nut locks the connector and the cane tip seat, the end of the cane tip seat can contact the flange, ensuring a tight positioning connection and effectively preventing the cane tip seat from wobbling relative to the connector.

[0010] Preferably, the connector has an extension extending towards the bottom of the cane tip seat, the diameter of which is smaller than that of the positioning portion. The bottom of the connection hole in the cane tip seat has a countersunk hole that mates with the extension. The extension increases the axial connection length between the cane tip seat and the connector, ensuring the connection strength. Furthermore, by providing a countersunk hole, the axial positioning area of ​​the connector and the cane tip seat is increased, which helps improve the stress condition at the locking nut and threads, thereby enhancing connection reliability.

[0011] Preferably, the outer surface of the locking nut is provided with anti-slip stripes.

[0012] Preferably, the connector has an axially arranged positioning hole, and the cane tip has a cane tip positioning part extending into the positioning hole of the connector. In this way, the end of the cane tip enters into the connector, and the connector also supports and positions the cane tip, effectively dispersing the pressure on the cane tip seat and preventing the cane tip seat from breaking.

[0013] The beneficial effects of this utility model are: (1) It enables quick disassembly and installation of the pole tip seat together with the pole tip, improving the convenience of disassembly and installation; (2) It enables quick disassembly and installation of the pole tip seat without prior disassembly of mud support, snow rails, etc., effectively reducing the difficulty of disassembly and installation and improving the efficiency of disassembly and installation; (3) Through the cooperation of locking nut and connector, the connection strength between pole tip seat and connector is effectively improved, making the connection between pole tip seat and pole tube reliable and ensuring the stability of use; (4) After the locking nut is loosened, it will not separate from the pole tube, avoiding the risk of loss due to the locking nut falling off, and ensuring the integrity of the pole; (5) It facilitates quick disassembly and replacement of the pole tip after the pole tip is worn, improving the convenience of maintenance; (6) It facilitates the replacement of different pole tips according to different usage scenarios, such as skiing, cross-country, hiking, achieving the purpose of one pole for multiple uses.

[0023] like Figure 1 , Figure 2In the illustrated embodiment, a detachable trekking pole tip structure includes a pole tube 1 and a pole tip seat 2 located at the bottom of the pole tube 1. A pole tip 3, made of tungsten steel, is located at the bottom of the pole tip seat 2. The pole tip 3 is inserted into the bottom of the pole tip seat 2 to form an integral structure fixed to the pole tip seat 2. A mudguard 21 is provided on the pole tip seat 2, which serves to prevent mud from entering the ground too deeply during use. Below the mudguard 21, the pole tip seat 2 has a snow rail thread 22 for installing a larger snow rail, thus facilitating the use of the trekking pole on snow.

[0024] like Figure 3 , Figure 4 As shown, a connector 5 is provided between the cane tube 1 and the cane tip 2. The end of the connector 5 near the cane tube 1 has a fixing part 51 that is fixed to the cane tube 1. The fixing part 51 is inserted into the cane tube 1 and fixed to the cane tube 1 with glue. Figure 5 , Figure 6 As shown, the cane tip seat 2 is provided with a connecting hole 24 that slides with the connector 5, the bottom of the cane tube 1 is fitted with a locking nut 4, the inner hole 45 of the locking nut 4 is provided with an internal thread 44, the cane tip seat 2 is provided with an external thread 23 that mates with the internal thread 44, and the cane tube 1 and the cane tip seat 2 are fixedly connected by the locking nut 4 and the cane tip seat 2 threaded connection.

[0025] like Figure 4 , Figure 5 As shown, the connector 5 is provided with a positioning part 54 for circumferential positioning of the cane tip seat 2. One of the positioning part 54 and the cane tip seat 2 is provided with at least one positioning key 55, and the other is provided with a sliding groove 25 adapted to the positioning key 55. In this embodiment, the positioning part 54 is provided with two positioning keys 55, and the connecting hole 24 of the cane tip seat 2 is provided with a sliding groove 25 corresponding to the positioning key 55. The positioning keys 55 are evenly arranged on the positioning part 54 to ensure uniform force distribution.

[0026] like Figure 3 , Figure 6 As shown, the inner hole 45 of the locking nut 4 has an inwardly protruding positioning protrusion 42 at the end away from the cane tip seat 2. The connecting piece 5 has a flange 52 with a diameter larger than the inner diameter of the positioning protrusion 42. After the locking nut 4 is tightened and fixed, the positioning protrusion 42 and the flange 52 abut axially, thereby ensuring a stable locking effect. Furthermore, after the cane tip seat 2 is removed, the locking nut 4 is limited to prevent it from detaching from the cane tube 1. The inner hole 45 of the locking nut 4 has a groove 43 between the internal thread 44 and the positioning protrusion 42, which matches the width of the flange 52. The outer surface of the locking nut 4 has anti-slip stripes 41, providing a good feel and preventing slippage.

[0027] like Figure 3 , Figure 4As shown, the connector 5 has an extension 53 extending towards the bottom of the cane tip seat 2. The diameter of the extension 53 is smaller than that of the positioning part 54. The bottom of the connecting hole 24 of the cane tip seat 2 has a countersunk hole 26 that mates with the extension 53. The extension 53 can provide a longer axial length, thereby ensuring the connection strength between the cane tip seat 2 and the cane tube 1. In addition, a positioning hole 56 is provided at the end of the connector 5 facing the cane tip 3. The positioning hole 56 is arranged along the axial direction of the connector 5. The inner end of the cane tip 3 has a cane tip positioning part 31, which extends into the positioning hole 56 of the connector 5. The connector 5 also plays a supporting and positioning role for the cane tip 3, thereby effectively dispersing the pressure on the cane tip seat 2 and improving the stress state.

[0028] In actual use, such as Figure 2 As shown, when it is necessary to disassemble the cane tip seat 2, loosening the locking nut 4 releases the fixation of the cane tip seat 2 and the locking nut 4. At this point, pulling downwards will remove the cane tip seat 2 from the connector 5, while the locking nut 4 remains at the bottom of the cane tube 1. When it is necessary to install the cane tip seat 2, first align the sliding groove 25 of the cane tip seat 2 with the positioning key 55 on the positioning part 54, and then slide the cane tip seat 2 so that the connector 5 enters the cane tip seat 2. Figure 7 As shown, after tightening the locking nut 4 downwards to fix the cane tip seat 2 to the cane tube 1, it can be used normally.

[0029] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
