Description

Technical Field

[0001] This utility model relates to the field of sports products, and in particular to an ice pick handle and a modular ice pick. Background Technology

[0002] As an essential piece of equipment in icy and high-altitude environments, the ice axe's structural design directly impacts climbing safety and operational efficiency. Most existing ice axes are fixed in one piece, with the handle's shape and functional modules pre-matched, making them suitable only for single or limited climbing environments.

[0003] In practical applications, different terrains have significantly different requirements for the mechanical performance, grip method and function of ice axes. Traditional one-piece ice axes are difficult to meet the needs of switching between multiple scenarios. Users need to carry multiple ice axes of different sizes, which increases the weight of the equipment and makes it inconvenient to carry.

[0004] To address the aforementioned issues, some existing technologies have attempted to adopt modular designs. However, their core drawback lies in the fact that the pickaxe handle is mostly an integrated structure, making it impossible to transform its form by replacing key components. The entire pickaxe handle still needs to be replaced, resulting in low modular efficiency.

[0005] Therefore, there is an urgent need for a modular ice axe handle and ice axe with a unified connection standard, adaptability to multiple scenarios by replacing key components of the handle, and a grip structure that is specifically optimized. Utility Model Content

[0006] The purpose of this invention is to overcome the problems of limited adaptability to various climbing scenarios and low modular efficiency of ice axes. This invention provides an ice axe handle and a modular ice axe structure, which facilitates the replacement of the ice axe handle according to various climbing scenarios, reduces the load on climbers' equipment, and meets the needs of climbers for different ice axe handle shape transformations.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a pickaxe handle, the pickaxe handle including an upper pickaxe handle, a lower pickaxe handle and a first fitting, one end of the upper pickaxe handle is provided with a guide rail groove structure, one end of the lower pickaxe handle is provided with a slider structure adapted to the guide rail groove, the slider structure is snapped onto the guide rail groove structure, and the first fitting fixes the slider structure of the lower pickaxe handle in the guide rail groove structure of the upper pickaxe handle.

[0008] Preferably, the guide rail groove is a T-shaped groove extending along the length direction of the pick handle, and the slider is a T-shaped structure adapted to the T-shaped groove.

[0009] Preferably, the outer shell of the pickaxe handle is provided with a first threaded hole, and the slider structure is provided with a second threaded hole that mates with the first threaded hole. The first assembly includes a first bolt and a first nut. After the first threaded hole and the second threaded hole are aligned, the first bolt passes through the first threaded hole and the second threaded hole and mates with the first nut to fix the pickaxe handle and the pickaxe lower handle together.

[0010] Preferably, the other end of the pick has a straight handle that matches an ice axe, or the other end of the pick has a curved handle that matches an ice axe, or the other end of the pick has a curved handle that matches pure ice climbing.

[0011] Accordingly, this utility model also discloses a modular ice axe, which includes the aforementioned handle, head, and tip, with the head and tip located at the other end of the handle.

[0012] Preferably, the pickaxe tip is provided with a connecting part at one end near the pickaxe handle, the connecting part is provided with at least two fixing holes, the pickaxe handle is provided with a matching hole at the corresponding position, and the pickaxe tip and the pickaxe handle are fixedly engaged by the fixing holes and matching holes through the second fitting.

[0013] Preferably, the pick head has an embedding portion, the connecting portion has a notch, the shape of the notch is complementary to that of the embedding portion, the pick head is pre-positioned by embedding into the notch, and the pick head and the pick tip are engaged to form a fitting structure.

[0014] Preferably, the pick handle is provided with a receiving groove adapted to the fitting structure, and the fitting structure formed by the pick head and the pick tip is embedded in the receiving groove and then axially fixed by the second fitting to form a fit.

[0016] Preferably, the pickaxe tip is an ice and snow mountaineering pickaxe tip, a pure ice climbing pickaxe tip, or a mixed ice and rock all-terrain pickaxe tip.

[0017] This invention provides an ice axe handle and a modular ice axe structure. By separating the handle into an upper handle and a replaceable lower handle, and ensuring that the sliding mechanism of different types of lower handles is standardized, different types of curved handles can be quickly switched. Combined with replaceable heads and tips, it adapts to various climbing scenarios, eliminating the need to carry multiple ice axes and improving equipment versatility and operational reliability. The modular ice axe allows each module to be easily disassembled into a separate structural unit after use, making assembly and carrying more convenient. Attached Figure Description

Detailed Implementation

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specifically, Figure 1 A three-dimensional assembly structure diagram of the pickaxe handle of this utility model is shown. The pickaxe handle includes an upper handle 2, a lower handle 3, and a first mounting component 1. The first mounting component 1 is located at the connection between the upper handle 2 and the lower handle 3, and it fixes the upper handle 2 and the lower handle 3 together. Here, the upper handle 2 and the lower handle 3 are detachably connected, specifically through the first mounting component 1. This detachable design allows the pickaxe handle to be disassembled into different modules, which shortens the length of the device and makes it easier to carry.

[0023] Figure 2 This is a three-dimensional exploded view of the pickaxe handle of this utility model. One end of the upper handle 2 has a guide rail groove 21, and one end of the lower handle 3 has a slider structure 31 adapted to the guide rail groove 21. The slider structure 31 is engaged with the guide rail groove 21. The first assembly 1 fixes the slider structure 31 of the lower handle 3 in the guide rail groove 21 of the upper handle 2. This detachable structure allows for quick replacement of lower handles with different functions, improving the equipment's adaptability to various scenarios and reducing carrying costs.

[0024] Specifically, the guide groove 21 is a T-shaped groove extending along the length of the upper handle 2, and the slider is a T-shaped structure adapted to the T-shaped groove. This large-area contact fit of the T-shaped structure increases the connection area between the upper handle 2 and the lower handle 3, allowing the force during climbing to be evenly transmitted through the contact surface, reducing localized stress concentration, lowering the risk of damage to components due to uneven force distribution, and extending the service life of the pickaxe handle. Furthermore, the outer shell of the upper handle 2 is provided with a first threaded hole 23, and the slider structure 31 is provided with a second threaded hole 32 that mates with the first threaded hole 23. The first assembly 1 includes a first bolt 11 and a first nut 12. After the first threaded hole 23 and the second threaded hole 32 are aligned, the first bolt 11 passes through the first threaded hole 23 and the second threaded hole 32 and then engages with the first nut 12 to fix the upper handle 2 and the lower handle 3 of the pickaxe together. The standardized design of the threaded connection can adapt to different types of lower handles 3, enabling the same upper handle 2 to stably engage with multiple lower handles 3, thus enhancing the versatility of the modular design.

[0025] Specifically, schematic diagrams of different structural forms of the pickaxe handle of this utility model are shown. Figure 2 The other end of the axe handle 3 shown has a straight handle that fits with an ice axe. The end of this straight handle has a sharp tip, the axis of which is collinear with the axis of the straight handle. The handle has perforated holes spaced along its length, with rounded edges. This sharp tip structure allows it to be inserted into the snow for stable support, while the perforated structure reduces weight while maintaining strength, making it suitable for the support and balance needs of walking on flat ground and gentle slopes.

[0026] It should be noted that, Figure 3 The diagram illustrates the structure of this invention, featuring a curved handle that mates with an ice axe. Specifically, the other end of the lower handle 33 has a curved handle that mates with the ice axe. This curved handle has a pre-defined arc shape. The end of the curved handle furthest from the upper handle 2 forms the grip area. This area has arc-shaped protrusions distributed along its length. These protrusions are symmetrically arranged along the axis of the grip area, forming a serrated elongated structure. A protrusion structure for assisting in force application is located on the side closest to the upper handle 2. This serrated arc-shaped protrusion structure enhances grip friction, preventing the ice axe from slipping out of the hand. It also facilitates arm support during force application, improving overall climbing efficiency.

[0027] Figure 4 The diagram illustrates the structure of this invention, showing a curved handle designed for pure ice climbing. Specifically, the other end of the axe lower handle 34 has a curved handle for pure ice climbing. This curved handle has a large-area-ratio curved shape, with the end of the curved handle originally separated from the axe upper handle 2 forming the grip area. This area has an arc-shaped surface that conforms to the contour of the hand grip. This large-area-ratio design conforms to the force trajectory of the hand hooking, reducing fatigue during prolonged gripping and enhancing control stability when hooking onto ice walls.

[0028] The pickaxe handle 3 in this utility model is designed in multiple forms. The pickaxe handle 3 is assembled with the same pickaxe handle 2 through a unified slider structure 31, so that one handle can be used in multiple scenarios. Users do not need to carry multiple ice axes. They can meet the functional requirements of different scenarios such as walking on flat ground, climbing steep slopes, and vertical ice walls by simply changing the pickaxe handle 3, which greatly reduces the weight of equipment and carrying costs.

[0029] Specifically, Figure 5 This diagram illustrates a three-dimensional assembly structure of the modular ice axe of this invention. The modular ice axe includes an upper handle 2, a lower handle 3, a pick 4, and a head 5. The upper handle 2 and the lower handle 3 are fixed together by a first fitting 1. One end of the lower handle 3 has a straight handle that mates with a mountaineering ice axe. The pick 4 is an ice and snow mountaineering pick, and the head 5 is a shovel head 52. For details regarding the structure of the upper handle 2 and the lower handle 3 connected by the first fitting 1, please refer to [reference needed]. Figures 1-5The details shown are not elaborated here. The ice and snow climbing axe tip 4 has a reverse arc-shaped working part, the curvature of which is adapted to the force direction of bending the axe body, and the upper teeth of the working part have a blunt structure; the ice and snow climbing axe tip, together with the straight handle of the ice axe, is adapted to the support and balance requirements of walking on flat ground and gentle slopes; the axe head 5 is a shovel head 52, with a flat blade and sharp edges; it can be used to cut steps in icy and snowy terrain, dig on the snow surface, clear the snow surface or dig snow holes, remove loose snow and decayed ice from the surface when setting up protection points, and serve as a braking tool in soft snow.

[0030] Specifically, Figure 6 An exploded perspective view of the pickaxe handle assembly component of this utility model is shown. The pickaxe handle assembly component includes a pickaxe tip 4, a pickaxe head 5, and a second fitting 6. The pickaxe tip 4 has a connecting portion 41 near the end of the pickaxe handle 2. The connecting portion 41 has at least two fixing holes 42. The pickaxe handle 2 has a corresponding matching hole 24. The pickaxe tip 4 and the pickaxe handle 2 are fixedly engaged by the second fitting 6 passing through the fixing holes 42 and matching holes 24. This structure avoids circumferential deflection or axial misalignment during the assembly of the pickaxe tip 4, ensuring that the working direction of the pickaxe tip 4 is consistent with the force direction of the pickaxe handle. It prevents misalignment between the force direction and the action direction of the pickaxe tip 4 due to assembly deviations, thus ensuring the stability and consistency of the climber's operation.

[0031] Furthermore, one end of the pick 5 is provided with an insert 51, the cross-section of which is triangular. The connecting part 41 is provided with a notch 43, the shape of which is complementary to that of the insert 51. The insert 51 is provided with rounded corners to guide the insert 51 to smoothly engage with the notch 43. The pick 5 is pre-positioned by engaging with the notch 43. The axes of the pick 5 and the pick tip 4 are not offset in a plane perpendicular to the axis of the pick handle 2, forming a coaxial fitting structure. The other end is a working part that can meet the auxiliary function requirements of some specific functions, such as hammering and shoveling snow.

[0032] Furthermore, the pick 5 and the pick tip 4 interlock to form a fitting structure. The pick handle 2 has a receiving groove 22 adapted to the fitting structure, ensuring that the fitting structure is flush with the outer wall of the pick handle 2 after being inserted. When the fitting structure formed by the pick 5 and the pick tip 4 is fully inserted into the receiving groove 22, the fitting structure has holes that correspond coaxially with the holes in the pick handle 2. After the fitting structure is inserted into the receiving groove 22, it is axially fixed by the second fitting 6 to form a fit. This standardized design continues the core advantage of modular ice axes, allowing users to quickly switch the function of the pick 5 according to the scene without replacing the pick handle 2, further improving the equipment's versatility.

[0033] It should be noted that the pickaxe 5 here can be a shovel head or a hammer head, specifically... Figure 6The pickaxe 5 shown is a shovel head 52, which can be used to shovel snow, shovel the ground, etc. in specific application scenarios.

[0034] Specifically, Figure 7 The diagram shows the structure of the first hammer head of this utility model. The first hammer head 53 has an embedding part 51 at one end and a striking part at the other end. The striking part is V-shaped, with the two sides of the blade converging towards the middle. The striking part is a raised hard block shape, and the force is concentrated at the apex of the V-shape, resulting in high local pressure and easy penetration of hard ice.

[0035] Specifically, Figure 8 The diagram shows the structure of the second hammer head of this utility model. One end of the second hammer head 54 is provided with an embedding part 51, and the other end is a striking part. The striking part is straight, with a flat cutting edge. The striking part is a raised hard block shape. When it penetrates the ice surface, the cutting edge is evenly stressed, the pressure is relatively low, and the ice surface is damaged over a large area. It is suitable for large-area hammering and excavation of ice walls.

[0036] It should be noted that the pickaxe tip in this embodiment of the invention is an ice and snow mountaineering pickaxe tip, a pure ice climbing pickaxe tip, or a mixed ice and rock all-terrain pickaxe tip.

[0037] Furthermore, Figure 9 The diagram shows the structure of the curved-handle climbing ice axe of this invention. The modular ice axe includes an upper handle 2, a lower handle 3, and a tip 4. The upper handle 2 and the lower handle 3 are fixed together by a first fitting 1. One end of the lower handle 3 has a curved handle that matches the mountaineering ice axe, and the tip 4 is a pure ice climbing ice axe tip.

[0038] The pure ice climbing axe tip has a smaller included angle at the tip 4 of its working part, resulting in a sharper cutting edge. The upper teeth of the working part have a blunt structure, with the tips of the blunt teeth forming a rounded transition. The curved handle that mates with the ice axe has a pre-defined curved shape. The end of the curved handle away from the upper handle 2 is the grip area, and this area has arc-shaped protrusions distributed along its length. These protrusions are symmetrically arranged along the axis of the grip area, forming a serrated strip structure. A protrusion structure for assisting in force generation is located on the side closer to the upper handle 2. This serrated arc-shaped protrusion structure enhances grip friction, preventing the ice axe from slipping out of the hand. The auxiliary force generation protrusion structure also facilitates arm support during force generation, improving overall climbing efficiency. For details regarding the assembly structure between the upper pickaxe handle 2 and the lower pickaxe handle 3 via the first assembly part 1, please refer to [link / reference needed]. Figures 1-5 The details shown will not be elaborated upon here. The curved-handle ice axe, as an all-around technical ice axe, offers greater versatility, is suitable for mixed routes, and is specifically designed for ice wall routes and technical climbing.

[0039] Furthermore, Figure 10The diagram shows the structure of the ice axe for pure ice climbing of this utility model. The modular ice axe includes an upper handle 2, a lower handle 3, and a tip 4. The upper handle 2 and the lower handle 3 are fixed together by a first fitting 1. One end of the lower handle 3 has a curved handle for pure ice climbing. The tip 4 is a hybrid ice and rock all-terrain tip.

[0040] The ice-rock hybrid all-terrain pickaxe tip features serrated teeth on its working section. The height of these teeth and the angle of the flat edge are adapted to the cutting requirements of ice-rock hybrid terrain. The upper teeth of the working section have a sharp structure with pointed edges at the tips. The curved handle, designed for pure ice climbing, has a large-area curvature. The end of the curved handle away from the upper handle 2 is the grip area, which has an arc-shaped surface that conforms to the contours of the hand. This large-area curvature design conforms to the force trajectory of the hand when hooking, reducing fatigue during prolonged gripping and enhancing control stability when hooking onto ice walls.

[0041] For details regarding the assembly structure between the upper pickaxe handle 2 and the lower pickaxe handle 3 via the first assembly part 1, please refer to [link / reference needed]. Figures 1-5 The details shown will not be elaborated upon here. Pure ice climbing ice axes are specifically designed for use as a support point for climbers on ice walls and mixed-type cliffs. For use on cliff terrain such as bulges, steep inclines, and overhangs, the axe handle has a large bend and a smaller blade angle, making hooking actions more efficient.

[0042] Furthermore, the above description provides a detailed overview of the modular structure pick handle and ice axe provided by the embodiments of this utility model. 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.
