Description

Technical Field

[0001] This utility model belongs to the field of walking sticks, and in particular relates to a walking stick with a replaceable tip structure. Background Technology

[0002] Existing trekking poles generally have non-detachable tip systems, meaning they cannot be taken on airplanes and must be checked in. This is primarily because the tips are quite sharp, and high-end trekking poles used in high-altitude, snow-covered, or trail running environments are expensive, making them prone to damage and loss during transport. For example, the applicant's previous Chinese patent application, publication number CN220937045U, disclosed a novel aluminum alloy trekking pole tip device. While it features a detachable tip, this is typically only replaced when the tip is severely worn. Disassembly usually requires specific tools, making it difficult for the average user to remove the tip, causing significant inconvenience in daily use. Utility Model Content

[0003] This invention provides a replaceable cane tip structure, which facilitates the separation of the cane tip from the cane tube and improves the convenience of daily use.

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

[0005] A replaceable tip structure for a walking stick includes a stick tube and a mud holder. The bottom of the mud holder has a stick tip. A connector is provided between the stick tube and the mud holder. The upper part of the connector is fixedly connected to the inside of the stick tube, and the lower part of the connector is threadedly connected to the mud holder. The middle part of the connector has a limiting end, and the limiting end has a limiting arc surface facing the mud holder. The mud holder has a mating arc surface that matches the limiting arc surface. After the connector and the mud holder are threaded together, the limiting arc surface and the mating arc surface fit together. Thus, the connector and the mud holder are connected by threads, allowing for easy disassembly and installation without the need for additional tools, improving daily usability. Furthermore, the mud holder effectively prevents soil from entering the mating area between the connector and the mud holder, reducing the difficulty of disassembly.

[0006] Preferably, the limiting arc surface is arranged circumferentially around the limiting end, and the limiting arc surface is provided with an arc-shaped limiting protrusion, while the mating arc surface is provided with a mating protrusion corresponding to the limiting protrusion. In this way, when the mud support is tightened to the connector, the limiting arc surface and the mating arc surface are circumferentially limited by the limiting protrusion and the mating protrusion, effectively preventing the mud support from falling off the connector and improving connection stability.

[0007] Preferably, there are at least two limiting protrusions on the limiting arc surface, and the limiting protrusions are evenly distributed along the limiting arc surface. The multiple protrusions between the limiting arc surface and the mating arc surface ensure more even force distribution and further guarantee the anti-detachment effect.

[0008] Preferably, the mud support has a countersunk hole that mates with the lower part of the connector, and the mating arc surface is disposed on the stepped surface of the countersunk hole. The countersunk hole can axially position the connector, improving the support effect of the mud support for the connector.

[0009] Preferably, the lower part of the connector has a cylindrical structure, the cylindrical structure is provided with external threads, and the inner wall of the countersunk hole is provided with internal threads that mate with the external threads.

[0010] Preferably, the upper part of the connector is provided with a connecting end, which is fixed to the inner wall of the cane tube, and the connecting end is provided with several annular grooves. The annular grooves can increase the contact surface with the cane tube and improve the connection reliability between the connector and the cane tube.

[0011] Preferably, the device also includes an extension rod detachably connected to the pole tube. One end of the extension rod has a threaded section that engages with the threaded connector, and the other end has a pin. Thus, by simply adding a matching extension rod to the pole tube, the pole can be used as a support pole for tents or tarps, greatly facilitating subsequent outdoor hiking and camping activities.

[0012] Preferably, the device also includes an extension rod detachably connected to the cane tube. The extension rod includes a rod body and a rod body connecting portion fixed to the rod body. The outer end of the rod body connecting portion has a threaded section that engages with a connecting piece, and the outer end of the rod body has another connecting piece. Thus, when the extension rod is used to form a support rod, it can be fixed to one end of the rod body as a jack using a mud support along with the cane tip.

[0013] Preferably, the device also includes an assembly with a 1 / 4-inch threaded post at one end and an internal threaded hole at the other end that mates with the threaded connection of the connector. This allows the mud stick to be disassembled and replaced with the assembly, which features a 1 / 4-inch threaded post for easy mounting of a camera or phone holder onto the stick for shooting.

[0014] The beneficial effects of this utility model are: (1) The mud support and the pole tip can be quickly separated from the pole tube, making it convenient for users to remove the pole tip when boarding the plane and carry it with them; (2) It reduces the difficulty of separating the pole tip and the pole tube, improving the user's convenience; (3) The mud support and the connector have an anti-fall-off function after being connected, improving the stability and reliability of the connection; (4) After the mud support is disassembled, it is convenient to connect the extension pole as a support pole for tents and tarps, which is convenient for subsequent outdoor hiking and camping activities; (5) After the mud support is disassembled, the assembly can be installed to facilitate the installation of a camera or mobile phone for shooting.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1

[0032] like Figure 1 In the illustrated embodiment, a replaceable cane tip structure includes a cane tube 1 and a mud support 2. A cane tip 4 is located at the bottom of the mud support 2. A cane holder 3 is typically provided between the cane tip 4 and the mud support 2. The cane holder 3 is fixedly connected to the bottom of the mud support 2, while the cane holder 3 and the cane tip 4 are detachably connected to facilitate the installation and replacement of the cane tip 4. Figure 2 , Figure 3 As shown, a connector 5 is provided between the cane tube 1 and the mud support 2. The upper part of the connector 5 is fixedly connected to the inside of the cane tube 1 by means of physical fixation or glue fixation.

[0033] The lower part of connector 5 is threadedly connected to mud support 2, such as... Figure 3 As shown, the connector 5 has a limiting end 5c in the middle, and the limiting end 5c protrudes radially from the connector 5. Figure 4 As shown, the mud support 2 has a countersunk hole 22 that mates with the lower part of the connector 5. The stepped surface of the countersunk hole 22 can axially limit the limiting end 5c to ensure accurate installation of the connector 5 and the mud support 2. The lower part of the connector 5 is a cylindrical structure 5b, which has an external thread 53. The inner wall of the countersunk hole 22 has an internal thread 23 that mates with the external thread 53. Figure 5 As shown, when the column structure 5b of the connector 5 is tightened with the mud support 2 by threads, the two are fixedly engaged.

[0034] like Figure 3 , Figure 4 As shown, the limiting end 5c has a limiting arc surface 52 on the side facing the mud support 2, and the mud support 2 has a mating arc surface 21 that matches the limiting arc surface 52. The mating arc surface 21 is set on the stepped surface of the countersunk hole 22. The limiting arc surface 52 is arranged circumferentially around the limiting end 5c, and the limiting arc surface 52 has an arc-shaped limiting protrusion 52a. The mating arc surface 21 has a mating protrusion 21a corresponding to the limiting protrusion 52a. There are at least two limiting protrusions 52a on the limiting arc surface 52, and the limiting protrusions 52a are evenly distributed along the limiting arc surface 52. Figure 5 As shown, after the connecting piece 5 and the mud support 2 are screwed together, the limiting arc surface 52 and the mating arc surface 21 fit together. When the connecting piece 5 and the mud support 2 are tightened, the limiting protrusion 52a on the limiting arc surface 52 enters between two adjacent mating protrusions 21a on the mating arc surface 21 to form a limit. At this time, a certain torsional torque is required to separate the connecting piece 5 and the mud support 2 to prevent the mud support 2 from falling off the bottom of the rod tube 1 during use.

[0035] In addition, such as Figure 3As shown, the upper part of the connector 5 is provided with a connecting end 5a, and the connecting end 5a is provided with several annular grooves 51. Figure 1 and Figure 6 As shown, the connector 5 is fixed to the inner wall of the tube 1 via the upper connecting end 5a.

[0036] In actual use, when it is necessary to separate the cane tip 4 from the cane tube 1, the cane tube 1 and the mud support 2 are rotated relative to each other, causing the limiting arc surface 52 and the mating arc surface 21 to separate, releasing their limiting relationship, and the mud support 2 can be easily removed from the bottom of the cane tube 1. When it is necessary to install the cane tip 4 onto the cane tube 1, the mud support 2 and the connector 5 are tightened with threads, ultimately causing the limiting arc surface 52 and the mating arc surface 21 to fit together for limiting, thus completing the installation of the cane tip 4.

[0037] like Figure 7 As shown, after disassembling the mud holder 2 along with the staff tip 4, an extension rod 6 can be fitted to the staff tube 1, combining... Figure 8 As shown, one end of the extension rod 6 has a threaded section 62, which can mate with the external thread 53 of the connector 5, thereby achieving a detachable connection between the extension rod 6 and the cane tube 1. The other end of the extension rod 6 has a pin 61, which is coaxially arranged with the extension rod 6. Figure 9 As shown, after the pole tube 1 is connected to the extension rod 6, the pin 61 at the end of the extension rod 6 can pass through the corresponding positioning holes of the tent 7, etc., and thus be used as a support pole for equipment such as tents and tarps, which is very convenient for subsequent outdoor hiking and camping activities.

[0038] Example 2

[0039] The difference between Example 2 and Example 1 is that, for example... Figure 10 As shown, the extension rod includes a rod body 6a and a rod body connecting part 6b. The rod body 6a and the rod body connecting part 6b can be fixedly connected by means such as glue. The outer end of the rod body connecting part 6b is provided with a threaded section 62, which facilitates fixing with the external thread of the connecting piece through thread engagement. The outer end of the rod body 6a is provided with another connecting piece 5, which facilitates connection with the mud support through the connecting piece.

[0040] In actual use, after the user disassembles the mud holder 2 along with the stick tip 4, an extension rod 6 can be fitted to the stick tube 1, combining... Figure 10 , Figure 11 As shown, one end of the extension rod 6 has a threaded section 62, which can mate with the external thread 53 of the connector 5, thereby achieving a detachable connection between the extension rod 6 and the cane tube 1. Another connector 5 is provided at the outer end of the extension rod, so the disassembled mud support 2, along with the cane tip 4, can be installed at the outer end of the extension rod 6. Figure 12As shown, when the pole tube 1 is connected to the extension pole 6, the pole tip 4 located at the outer end of the extension pole 6 can pass through the corresponding positioning holes of the tent 7, etc., and thus be used as a support pole for equipment such as tents and tarps, which is very convenient for subsequent outdoor hiking and camping activities.

[0041] Example 3

[0042] The difference between Example 3 and Example 1 is that, for example... Figure 13 As shown, it also includes assembly 9, one end of which has a 1 / 4-inch threaded post 8, and the other end of which has an internal threaded hole that mates with the threaded connection of the connector. In this embodiment, another mud support can be used to install the 1 / 4-inch threaded post as an assembly, thereby effectively saving production costs.

[0043] In actual use, after the user disassembles the mud holder 2 along with the staff tip 4, as follows: Figure 13 , Figure 14 As shown, the assembly 9 with the 1 / 4-inch threaded post 8 can be mounted on the connector of the cane tube. Since the bottom of the camera and the phone holder usually have 1 / 4-inch threaded holes, as in this embodiment, the phone clip 11 is fixed to the assembly 9, and the phone 10 is clamped in the phone clip 11. In this way, the camera and the phone can be fixed to the assembly 9, making it convenient for the user to take pictures.

[0044] 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.
