[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0030] Embodiment: As shown in the figure, the convertible outdoor hiking shoes of this embodiment include a sole and an upper arranged on the sole, and also include spikes 1 and a driving mechanism. The sole is provided with spike holes, and the spikes 1 are placed at positions in the sole corresponding to the spike holes. The driving mechanism is transmission-connected with the spikes 1 and is used to drive the spikes 1 to extend out of the sole from the corresponding spike holes, or retract into the sole.

[0031] More specifically, the sole is divided into two layers (upper sole a and lower sole b), which is a combined structure, which facilitates the installation and arrangement of studs and other components inside the sole.

[0032] During use, the driving mechanism is adjusted according to usage requirements to drive the spikes 1 to extend out of the sole or retract, thereby adjusting the two usage modes of climbing and walking or running. Specifically, when climbing, the spikes 1 extend out of the bottom of the sole, and when walking or running normally, the spikes are retracted into the sole. The entire technical solution has a reasonable structural design and can adjust the two modes of climbing and normal walking and running according to needs. It has diversified functions and is relatively convenient to use.

[0033] Preferably, the bottom of the above-mentioned sole is evenly provided with anti-skid protrusions 11, and the front part of the above-mentioned bottom of the above-mentioned sole is provided with a protective protrusion 12, and the protective protrusion 12 is provided with the above-mentioned nail hole passing through it from top to bottom. When the above-mentioned shoe spikes 1 move downward to extend out of the corresponding above-mentioned nail holes, they protrude below the anti-skid protrusions 11 of the above-mentioned bottom of the sole.

[0034] In this embodiment, the anti-slip protrusion 11 is reasonably designed and adopts a conventional rubber sole structure on the market. The protective protrusion 12 can play a certain protective role on the shoe spike 1. The nail hole thereon is designed to be concealed. It is preferably made of a material with good elasticity, extrusion resistance, a sense of control and sealing for the extrusion or retraction of the shoe spike, so as to prevent external ground water from penetrating into the shoe.

[0035] As a preferred embodiment, Figure 3 , 5 As shown in Figure 6, the driving mechanism includes a long strip shell 21, a bow plate 22 and a telescopic component. The shell 21 is arranged across the interior of the front part of the sole, and slideways are provided on both sides of the top length direction of the interior thereof, and a through hole is provided in the middle of the bottom wall for the shoe spike 1 to pass through. The bow plate 22 is an arc-shaped plate with an opening upward, and its two ends are respectively slidably connected with the two ends of the slideways on both sides of the top of the shell 21, and its arc top is located above the through hole. The shoe spike 1 is fixed to the outer side of the arc top of the bow plate 22, and the telescopic component is installed in the shell 21 and connected to the inner side of the arc top of the bow plate 22. The telescopic component is used to drive the arc top of the bow plate 22 to move up and down, and drive the two ends of the bow plate 22 to slide relatively close or away along the slideways on both sides, so that the shoe spike 1 extends out of the sole from the corresponding nail hole, or retracts into the shell 21.

[0036] In this embodiment, when the telescopic component is extended, the arc opening of the bow plate 22 can be driven to contract, that is, the two ends of the bow plate 22 are relatively moved closer along the slide, and the top of the arc moves downward, and drives the shoe spike 1 to move downward gradually through the spike hole and extend out of the sole. The overall structural design is reasonable, and the operation is simple and convenient.

[0037] As a preferred embodiment, Figure 4-10As shown, the telescopic assembly includes a columnar nut 231, a screw rod 232, a screw rod sleeve 233, a rotary disk 234, a positioning column 235, a stretching assembly and a rotary drive assembly. The inner side of the arc top of the bow plate 22 is fixed with an arc-shaped bow pestle 221 that matches it. One end of the nut 231 is laterally rotatably connected to the inner side of the bow pestle 221. One end of the screw rod 232 is screwed into the other end of the nut 231. The screw rod sleeve 233 is fixed to the other end of the screw rod 232 and is provided with a protruding engaging portion 2331 at its end. One end of the positioning column 235 is laterally rotatably connected to the top wall of the shell 21 corresponding to the position above the arc top of the bow plate 22. The rotary disk 234 is rotatably connected to the positioning column 235. The other end of the positioning column 235 is provided with a slot 2341 that matches the above-mentioned engaging portion 2331 at its end. The above-mentioned stretching assembly is movably connected with the above-mentioned screw sleeve 233, and the above-mentioned rotation drive assembly is transmission-connected with the above-mentioned turntable 234. The above-mentioned rotation drive assembly and the above-mentioned stretching assembly can synchronously pull the above-mentioned turntable 234 and the positioning column 235 and the above-mentioned screw sleeve 233 and the screw 232 two groups of components to rotate laterally and vertically, and make the ends of the above-mentioned screw sleeve 233 and the turntable 234 contact, and make the above-mentioned engaging portion 2331 engage in the above-mentioned slot 2341, or synchronously pull the above-mentioned turntable 234 and the screw sleeve 233 to rotate laterally until the two are separated and form an angle, thereby driving the above-mentioned bow plate 22 to drive the shoe spike 1 to move up and down.

[0038] In this implementation, the use process is as follows:

[0039] ① When adjusting the climbing mode, the screw sleeve 233 and the rotary disk 234 are pulled by the stretching assembly and the rotary drive assembly respectively, so that the screw sleeve 233 and the screw rod 232 are rotated sideways to a vertical state, and the rotary disk 234 and the positioning column 235 are rotated sideways to a vertical state, and the ends of the screw sleeve 233 and the rotary disk 234 are in contact with each other, and the engaging portion 2331 is engaged with the engaging groove 2341, so that the rotary disk 234 and the screw sleeve 233 are connected as a whole and form a linkage state. Next, the rotary drive assembly acts on the rotary disk 234, so that the rotary disk 234 rotates, which can drive the screw sleeve 233 to rotate, thereby rotating the screw rod 232, and finally making the nut 231 move downward relative to the screw rod 232 under the condition of rotation constraint, that is, pushing the bow pestle 221 and the bow plate 22 downward, prompting the shoe spike 1 to move downward through the nail hole;

[0040] ② Adjust the walking or running mode, and the studs 1 can be retracted by driving the rotary disc 234 to rotate in the opposite direction through the rotary drive assembly. The whole design is reasonable and easy to operate.

[0041] As a preferred embodiment, the tensioning assembly includes a mounting shell 31, a first elastic member 32, a second elastic member 33, a first cable 34, a second cable 35 and a connecting tube 36. The mounting shell 31 is strip-shaped and is vertically mounted on one side of the housing 21 at a position corresponding to the top of the arc of the bow plate 22. One end of the connecting tube 36 extends close to the screw sleeve 233 and the rotary disk 234, and tension springs 361 are fixed on both sides of one end of the connecting tube 36. An annular groove is provided on the outer periphery of the screw sleeve 233. A tension rope 362 is connected between the two tension springs 361. The tension rope 362 is wrapped around the annular groove. The first elastic member 32 is arranged along the length direction of the mounting shell 31. The first stopper 321 is arranged at one end of the mounting shell 31 close to the housing 21, and the other end is connected to the end of the mounting shell 31 away from the housing 21. One end of the first cable 34 passes through the end of the mounting shell 31 away from the housing 21, and is connected to the other end of the connecting pipe 36 after passing through the other end of the mounting shell 31. A strip-shaped assembly shell 37 perpendicular to the strip-shaped assembly shell 37 is fixed to the side of the end of the mounting shell 31 away from the housing 21. The second elastic member 33 is arranged in the assembly shell 37 along the length direction. The second stopper 331 is arranged at one end of the mounting shell 31 close to the mounting shell 31, and the end of the second stopper 331 away from the second elastic member 33 is provided with a strip-shaped assembly shell 37 along the length direction. 37, one end of the columnar pull card 332 away from the second baffle 331 passes through the corresponding side of the mounting shell 31 and extends into the interior of the mounting shell 31. The side of the end of the columnar pull card 332 passing through the mounting shell 31 close to the first baffle 321 is set as a first inclined surface. The first baffle 321 corresponds to the columnar pull card 332 and the side close to it is set as a second inclined surface. The second inclined surface coincides with the first inclined surface. One end of the second cable 35 passes through the side wall of the end of the assembly shell 37 away from the mounting shell 31 and extends to connect with the second baffle 331. The other ends of the first cable 34 and the second cable 35 pass through the upper The inside of the sole is located at a channel set between the heel of the sole and the shell 21, and passes through the heel of the sole. The first cable 34 is used to pull the first baffle 321 to move to the second inclined plane to slide over the first inclined plane under the action of external force, and synchronously compress the first elastic member 32. At the same time, the screw sleeve 233 and the screw 232 are pulled laterally to rotate vertically through the connecting tube 36, the tension spring 361 and the tension rope 362. The second cable 35 is used to pull the second baffle 331 and the columnar pull card 332 away from the mounting shell 31 under the action of external force, so that the columnar pull card 332 and the second baffle 331 are disengaged and avoid the first baffle 321.

[0042] This embodiment specifically provides the technical means of stretching the assembly, and the operation process is as follows:

[0043] ① When adjusting the mountain climbing mode, the first cable 34 is pulled outward at the heel, and the first cable 34 directly pulls the connecting tube 36 and the first barrier 321. The connecting tube 36 then pulls the screw rod sleeve 233 and the screw rod 232 to rotate laterally through the tension spring 361 and the tension rope 362. In this process, until the second inclined surface at the side end of the first barrier 321 slides over the first inclined surface and is engaged with the side close to it after the first inclined surface slides over, the position of the first barrier 321 is blocked by the columnar pull card 332 and will maintain the current position after the external force is removed. In this state, the screw rod 232 is just in a vertical state (in this state, the shoe spike 1 moves downward but does not completely pass through the nail hole), and then the synchronous operation of the rotating drive assembly can realize the extension operation of the shoe spike 1 (the shoe spike 1 completely passes through the nail hole to the limit position);

[0044] ② To adjust the walking or running mode, just pull the second cable 35 outward, so that the second cable 35 drives the second barrier 331 and the columnar pull card 332 to move until the columnar pull card 332 retracts to avoid the first barrier 321, and the first barrier 321 can move back to its original position under the elastic force recovery of the first elastic member 32, and then cooperate with the elastic deformation recovery of the bow plate 22 and the force of the rotation drive assembly to make the screw rod 232 return to the inclined state.

[0045] Preferably, the first elastic member 32 and the second elastic member 33 are both strip-shaped springs.

[0046] As a preferred embodiment, Fig.11 As shown, the rotation drive assembly includes a third cable, and the third cable includes a left cable 41 and a right cable 42. A groove is arranged around the outer periphery of the rotary disk 234. One ends of the left cable 41 and the right cable 42 enter from opposite sides of the groove respectively, surround the groove, and are fixed at opposite sides of the groove. The other ends of the left cable 41 and the right cable 42 pass through the connecting pipe 36 and the mounting shell 31 respectively, and pass out from the other end of the mounting shell 31 away from the housing 21 and then pass through the passage from the upper The heel of the sole is passed through, and the other ends of the left cable 41 and the right cable 42 are connected to each other. Under the action of external force, one of the left cable 41 and the right cable 42 is pulled, and the above-mentioned turntable 234 is driven to rotate forward and reversely, and the above-mentioned screw rod 232 engaged with it is driven to rotate through the above-mentioned turntable 234, so that the above-mentioned nut 231 moves up and down relative to the above-mentioned screw rod 232, and drives the arc top of the above-mentioned bow plate 22 to move up and down, thereby driving the above-mentioned shoe spike 1 to extend out of the sole from the corresponding above-mentioned nail hole, or retract into the above-mentioned shell 21.

[0047] In this embodiment, after the engaging portion 2331 and the engaging groove 2341 are engaged with each other (that is, when the screw rod 232 and the positioning column 235 are both in a vertical state), the left cable 41 / right cable 42 is pulled to make the rotary disk 234 rotate clockwise / counterclockwise, thereby driving the screw rod 232 to rotate, so that the nut 231 moves downward to push the bow plate 22 to drive the shoe spike 1 to completely pass through the nail hole to the limit position. When switching the walking mode, the right cable 42 / left cable 41 is pulled to make the rotary disk 234 rotate counterclockwise / clockwise, thereby driving the screw rod 232 to rotate in the opposite direction, so that the nut 231 moves upward to make the bow plate 22 drive the shoe spike 1 to retract, and then, cooperate with the stretching component to make the bow plate 22 drive the shoe spike 1 to completely retract into the sole. The overall structural design is reasonable, and only two ropes need to be pulled during operation, which is very simple and convenient.

[0048] As a preferred embodiment, a ring patch 6 is provided at the heel of the above-mentioned upper, and the other ends of the above-mentioned first cable 34, second cable 35, left cable 41 and right cable 42 respectively pass through the matching through holes on the above-mentioned ring patch 6 and are respectively provided with pull rings.

[0049] In this embodiment, the design of the annular patch 6 can constrain the other ends of the first cable 34, the second cable 35, and the left cable 41 and the right cable 42 at their height positions to prevent wear on the ground or trampling that affects normal use.

[0050] Preferably, the engaging portion 2331 is a cylindrical structure, and its outer circumference is provided with external teeth, and the engaging groove 2341 is a circular groove adapted thereto, and its inner wall is provided with matching internal teeth.

[0051] This design enables the engaging portion 2331 and the engaging slot 2341 to be tightly engaged with each other through the matching of the inner and outer teeth of the engaging portion 2331 and the engaging slot 2341 .

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
