Specific implementation

[0025] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range of the utility model protection.

[0026] Embodiment one: please refer to Figure 1 - Figure 6 The utility model provides the following technical scheme: a kind of mountaineering shoes with adjustable shoe sole hardness, including shoe sole 1, shoe face 2 is installed on the top of shoe sole 1, and reinforcing pad 3 is installed in shoe sole 1;Reinforcing pad 3 is formed by movable strip 4 of equidistance distribution, and movable strip 4 is connected to form reinforcing pad 3 with head-to-tail, and connecting strip 6 is fixedly connected on one side of movable strip 4, and the side of movable strip 4 away from connecting strip 6 is equipped with connecting groove 5, and each movable strip 4 is connected by connecting groove 5 and connecting strip 6 to form reinforcing pad 3;Adjusting structure for adjusting the hardness of reinforcing pad 3 is installed on the back side of shoe sole 1;Reserved hole 7 is equipped in movable strip 4, and the reserved hole 7 in each movable strip 4 is on same straight line, and pull rope 8 is installed in reserved hole 7.

[0027] When user wears mountaineering shoes, the pressure of foot will act on shoe sole 1, and reinforcing pad 3 in shoe sole is extruded, and the hardness of shoe sole is adjusted, and reinforcing pad 3 is formed by multiple equidistance distribution movable strips 4, and each movable strip 4 is connected by connecting groove 5 and connecting strip 6, to form an integral reinforcing pad 3.

[0028] When the mountain climbing shoes step on the ground, the sole 1 will be deformed according to the shape of the ground. Since the reinforcing pad 3 is composed of a plurality of movable strips 4, and these movable strips 4 are connected through connecting grooves 5 and connecting strips 6, when the sole 1 is bent or pressed, the adjacent movable strips 4 can rotate around their connecting parts, adapt to the deformation of the sole, so that the whole reinforcing pad 3 can change synchronously with the sole, thereby ensuring the comfort and stability of walking.

[0029] The inside of the movable strip 4 is provided with a reserved hole 7, and the pull rope 8 penetrating through it can control the overall tightness of the reinforcing pad 3. When the pull rope 8 is tightened, the connection between the adjacent movable strips 4 is more firm, inhibiting the rotation ability, making the reinforcing pad 3 more rigid, and thus increasing the hardness of the sole 1, improving the supporting force, and being suitable for use in rough terrain or under heavy load.

[0030] On the contrary, when the pull rope 8 is loose, the connection between the movable strips 4 becomes loose, and the rotation range of the movable strips 4 increases, making the reinforcing pad 3 overall soft, allowing the sole 1 to more easily adapt to the ground shape, enhancing the fitting ability to irregular terrain, and improving the comfort.

[0031] Example two: on the basis of example one, the adjusting structure is also disclosed, and the specific structure is as follows: the adjusting structure comprises a mounting shell 9 mounted at the rear end of the sole 1, and a knob 10 is rotatably connected inside the mounting shell 9, and one end of the pull rope 8 away from the reinforcing pad 3 extends to the inside of the mounting shell 9; the knob 10 is fixedly connected with a winding ring 11 on the side close to the inside of the mounting shell 9, and the winding ring 11 is rotatably connected inside the mounting shell 9, and the pull rope 8 inside the mounting shell 9 is wound outside the winding ring 11; a fixed column 12 is fixedly connected in the middle of the inside of the mounting shell 9, and a ratchet 13 is slidably connected outside the fixed column 12, and the fixed column 12 and the ratchet 13 are both inside the winding ring 11; a first spring 14 is mounted outside the fixed column 12, and the two ends of the first spring 14 are fixedly connected between the ratchet 13 and the mounting shell 9, respectively; a plurality of elastic strips 18 are fixedly connected inside the winding ring 11 in a ring shape at equal intervals, and the elastic strips 18 are snap-connected outside the ratchet 13; a button 15 is slidably connected inside the knob 10, a pressure sleeve 16 is fixedly connected to the side close to the inside of the knob 10, and the pressure sleeve 16 and the ratchet 13 are in close contact with each other, and a second spring 17 is fixedly connected between the side of the button 15 and the inside of the knob 10.

[0032] When the user rotates the knob 10, the knob 10 drives the winding ring 11 fixedly connected inside to rotate, since one end of the pull rope 8 extends to the inside of the mounting shell 9 and is wound outside the winding ring 11, therefore, with the rotation of the winding ring 11, the pull rope 8 is gradually tightened or loosened, the tightness of the pull rope 8 in the reserved hole 7 directly determines the connection strength between the movable strips 4, thereby affecting the overall rigidity of the reinforcing pad 3, and finally changing the hardness of the sole 1.

[0033] The inside of the winding ring 11 is fixedly connected with elastic strips 18 in the form of a ring and equidistant distribution, the elastic strips 18 are clamped outside the ratchet 13, when the winding ring 11 rotates, the elastic strips 18 slide along the ratchet 13 and form one-way limiting with the ratchet 13, so that it can only rotate in one direction and cannot reverse, thereby ensuring that the pull rope 8 remains in a set state of tightness and cannot be automatically loosened.

[0034] If the user wants to reduce the hardness of the sole and make it softer to adapt to more flexible walking needs, the button 15 can be pressed, the button 15 drives the pressure sleeve 16 to move, when the button 15 is pressed, the pressure sleeve 16 connected inside will move towards the ratchet 13 and form a close fit with the ratchet 13, thereby releasing the limitation of the ratchet 13 and the elastic strips 18, the pressure sleeve 16 pushes the ratchet 13 to slide along the fixed column 12, so that the first spring 14 is compressed.

[0035] In this process, the fixed column 12 also moves towards the mounting shell 9, until the ratchet 13 is completely separated from the elastic strips 18, since the ratchet 13 is separated from the clamping relationship with the elastic strips 18, at this time the winding ring 11 loses the limitation and can rotate freely, the pull rope 8 can be relaxed, the connection strength of the movable strips 4 is reduced, the reinforcing pad 3 becomes softer, thereby reducing the hardness of the sole 1 and improving the comfort.

[0036] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "connected" and "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
