[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0025] As Figures 1-7The utility model discloses a kind of deformation-preventing shoe soles, including outsole 1, midsole 2 and insole 3, the insole 3 is located above midsole 2 and midsole 2 is located above outsole 1, the outsole 1 bottom is provided with several friction lines 11, the midsole 2 is provided with the installation cavity 21 for insole 3 insertion, the midsole 2 protrudes several positioning inserts 32 upwards, each positioning insert 32 is inserted midsole 2 and both ends are abutted with midsole 2, the insole 3 is located in the rear positioning insert 32 rear of right rear and is provided with the reinforcing framework 33 for increasing the internal strength of midsole 2, 1. in the process of assembling outsole 1, midsole 2 and insole 3, when insole 3 is loaded into the installation cavity 21 of midsole 2, each positioning insert 32 on midsole 2 will be inserted into the corresponding position of insole 3 in turn to complete the relative position determination of midsole 2 and insole 3, at this time, midsole 2 will not be relatively moved compared to insole 3 without the action of external force, and it is convenient for the connection and fixation of insole 3 and midsole 2;2. after insole 3 is loaded into the installation cavity 21 of midsole 2, at this time, since the left and right ends of positioning insert 32 are abutted with midsole 2, they can evenly distribute pressure to the inner wall of midsole 2, and when midsole 2 is deformed under stress, at this time, the force reaches between insole 3 and midsole 2, the reaction force of each positioning insert 32 can be outward to insole 3 and then make the circumferential direction of insole 3 abut with the inner wall of midsole 2 to increase the rigidity and stability of the whole structure;3. in addition, since midsole 2 is located at the rear side of each positioning insert 32 and is also provided with reinforcing framework 33, it can also increase the strength of insole 3, thereby improving the anti-deformation ability of the whole shoe sole.

[0026] Among them, each positioning insert 32 includes several front protruding sections 321 and rear protruding sections 322, each rear protruding section 322 is located between adjacent front protruding sections 321, and each front protruding section 321 is arranged in an arc shape with an opening facing forward. Since each front protruding section 321 is arranged in an arc shape with an opening facing forward, the volume occupied by each front protruding section 321 in the longitudinal direction is increased, thereby being able to exert a reaction force on more longitudinal positions of insole 3 so that the circumferential direction of insole 3 can abut with the inner wall of midsole 2.

[0027] Preferably, each rear protruding section 322 is arranged in an arc shape with an opening facing backward. Since each rear protruding section 322 is arranged in an arc shape with an opening facing backward, the volume occupied by each rear protruding section 322 in the longitudinal direction is increased, thereby being able to exert a reaction force on more longitudinal positions of insole 3 so that the circumferential direction of insole 3 can abut with the inner wall of midsole 2.

[0028] The reinforcing framework 33 comprises a plurality of lateral segments 331, longitudinal segments 332 and matching segments 333. Each lateral segment 331 is arranged on a longitudinal segment 332 in the up-down direction, and the left and right sides of each lateral segment 331 abut the inner wall of the midsole 2. Each matching segment 333 is connected to the lateral segment 331 of the bottom and one end is connected to the bottom of the midsole 2. The reinforcing framework 33 is composed of lateral segments 331, longitudinal segments 332 and matching segments 333. This multi-directional support structure can effectively improve the overall rigidity of the midsole 2, prevent excessive bending and twisting of the sole in multiple directions, thereby prolonging the service life of the shoe and improving the wearing comfort.

[0029] The inner sole 3 is provided with a plurality of matching plug blocks 31 protruding downward. Each matching plug block 31 comprises a matching column 311 made of rubber or other easily deformed material. The midsole 2 is provided with a matching groove 23 corresponding to each matching column 311. Each matching groove 23 is inclined from top to bottom and from inside to outside. Since each matching column 311 is made of easily deformed material and the matching groove 23 corresponding to each matching column 311 is inclined, when the inner sole 3 is installed in the mounting cavity 21 and each matching column 311 reaches the corresponding matching groove 23, each matching column 311 will deform along the direction of each matching groove 23. At this time, each matching column 311 is in an inclined state. Since the positioning plug blocks 32 are arranged, the inner sole 3 cannot move relative to the outer sole 1. Therefore, each matching column 311 can be stably deformed into an inclined state and apply an outward force to each matching column 311, so that the circumference of the inner sole 3 is in close contact with the inner wall of the midsole 2.

[0030] The midsole 2 protrudes into the mounting cavity 21 and is provided with a resisting member 22 made of rubber or other easily deformed material. The bottom of the resisting member 22 abuts the inner sole 3. Since the resisting member 22 is connected to the midsole 2 and the bottom abuts the inner sole 3, when the inner sole 3 is installed in the mounting cavity 21, the circumference of the inner sole 3 first passes over the resisting member 22 before the positioning plug blocks 32 are inserted into the inner sole 3. When the inner sole 3 has passed over the resisting member 22, each matching column 311 deforms towards the corresponding matching groove 23. Since the inner sole 3 cannot pass over the resisting member 22 without external force, the resisting member 22 applies a downward force to the inner sole 3, so that each matching column 311 is stably pressed and deformed into an inclined state in the corresponding matching groove 23.

[0031] Preferably, the cross-section of the resisting member 22 is triangular with a narrow top and a wide bottom. This shape not only increases the contact area between the resisting member 22 and the inner sole 3, providing more uniform support, but also reduces the thickness of the resisting member 22, thereby facilitating the deformation of the resisting member 22 under stress and the installation of the inner sole 3 into the mounting cavity 21.

[0032] The above description of disclosed embodiments enables one of ordinary skill in the art to make or use the application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
