DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: Please refer to Figure 1-Figure 5 A PU women's shoe with an easily replaceable sole comprises a shoe body 1, an upper bottom plate 2 is fixedly connected to the bottom of the shoe body 1, a lower bottom plate 3 is arranged at the bottom of the upper bottom plate 2, a connecting hole 21 is opened on the bottom peripheral side of the upper bottom plate 2, a limiting hole 22 is arranged at one end of the bottom of the upper bottom plate 2, a connecting block 31 is fixedly connected to the top peripheral side of the lower bottom plate 3, a limiting block 32 is arranged at one end of the top of the lower bottom plate 3, a control groove 4 is opened at one end of the lower bottom plate 3, the connecting hole 21 is matched with the connecting block 31, the limiting block 32 is matched with the limiting hole 22, a fixing groove is connected to one side of the connecting hole 21, a notch is arranged on the fixing groove on one side of the connecting hole 21, the connecting block 31 is divided into an upper and lower layers, the width of the upper layer of the connecting block 31 is greater than the width of the lower layer, and the width of the lower layer of the connecting block 31 is the same as the width of the notch.

[0025] Specifically, when connecting, the connecting block 31 on the lower base plate 3 is aligned with the connecting hole 21, so that the connecting block 31 enters the connecting hole 21, and then the user moves toward the fixing groove, and uses the lower layer of the connecting block 31 to adapt to the notch, so that the connecting block 31 enters the fixing groove, and at the same time uses the notch to limit the connecting block 31, and the width of the notch is the same as the width of the lower layer of the connecting block 31 and is smaller than the width of the upper layer of the connecting block 31, so that the upper layer of the connecting block 31 is blocked by the notch after entering the fixing groove, and prevents it from falling off downward, thereby preventing the upper and lower separation during use; the adaptation of the limit block 32 to the limit hole 22 enables the limit hole 22 to prevent the limit block 32 from moving horizontally, thereby preventing the lower base plate 3 from moving horizontally relative to the upper base plate 2;

[0026] Thus, the connecting block 31 is installed in the fixing groove on one side of the connecting hole 21 to prevent the upper base plate 2 and the lower base plate 3 from being separated up and down. At the same time, the limiting block 32 enters the limiting hole 22 to prevent the upper base plate 2 and the lower base plate 3 from being separated horizontally, thereby achieving a fixed connection between the upper base plate 2 and the lower base plate 3 and preventing the connection between the upper base plate 2 and the lower base plate 3 from being loosened.

[0027] Example 2: To achieve a quick connection between the upper base plate 2 and the lower base plate 3, please refer to Figure 1-Figure 5 On the basis of Example 1, the control groove 4 is connected to the movable groove 35, the movable groove 35 is arranged at one end of the control groove 4, and the limit block 32 is slidably arranged in the movable groove 35;

[0028] The bottom of the movable groove 35 is fixedly connected with a slide rod 34, one end of which passes through the bottom of the limit block 32 and is arranged in a slide groove 321 inside the limit block 32. A through hole is opened on one side of the top of the slide groove 321 to communicate with the outside.

[0029] The bottom of the limit block 32 is connected with a first spring 36 , the limit block 32 is connected to the bottom of the moving groove 35 through the first spring 36 , and the slide bar 34 is arranged in the first spring 36 ;

[0030] A dial plate 33 is fixed to one side of the bottom of the limit block 32, and the dial plate 33 is arranged in the control slot 4;

[0031] The end of the control slot 4 away from the limit block 32 is rotatably connected to a baffle plate 5, and the baffle plate 5 is provided with moving holes 51 on both the upper and lower sides. A second spring 53 is installed inside the moving hole 51, and one end of the second spring 53 is connected to a slider 52, which is slidably arranged in the second spring 53, and the slider 52 is adapted to the moving hole 51;

[0032] A pull slot 41 is formed on one end of the control slot 4 .

[0033] Specifically, the dial plate 33 can control the limit block 32 to move along the slide rod 34. When installing the connecting block 31 into the connecting hole 21, the user needs to first use the dial plate 33 to control the limit block 32 to retract into the moving groove 35 to prevent the limit block 32 from blocking the installation of the connecting block 31. When the limit block 32 retracts into the moving groove 35, the limit block 32 squeezes the first spring 36, causing the first spring 36 to undergo elastic deformation. When the connecting block 31 is installed into the connecting hole 21, the lower base plate 3 fits with the upper base plate 2. At this time, the upper base plate 2 The first spring 36 pushes the limit block 32 into the limit hole 22, thereby realizing the quick connection between the lower base plate 3 and the upper base plate 2. The through hole provided at the top of the slide groove 321 is used to connect the slide groove 321 with the outside, so that the slide rod 34 can move more conveniently in the slide groove 321. The slide rod 34 can guide the movement of the limit block 32, making its movement more stable.

[0034] Positioning holes are provided on the upper and lower sides of one end of the control groove 4. In a normal state, the slider 52 is adapted to the positioning holes so that the baffle 5 can be closed with the control groove 4. The baffle 5 is used to protect the paddle 33 and prevent dust and impurities from entering the control groove 4. The paddle groove 41 at one end of the control groove 4 can be used to pry one end of the baffle 5 to rotate around the other end. One end of the slider 52 is hemispherical. During this process, the edge of the positioning hole squeezes one end of the slider 52, so that the slider 52 moves into the moving hole 51 and squeezes the second spring 53. At this time, the slider 52 disengages from the positioning hole to achieve the opening of the baffle 5.

[0035] Working principle: when replacing the sole, the user controls the baffle plate 5 to rotate through the dial groove 41, causing the slider 52 in the baffle plate 5 to disengage from the positioning hole, thereby opening the baffle plate 5. After the baffle plate 5 is opened, the user can dial the dial plate 33 toward the bottom of the control groove 4, so that it drives the limit block 32 to move downward. During this process, the limit block 32 squeezes the first spring 36, so that the limit block 32 can enter the inside of the moving groove 35 along the slide rod 34, and the limit block 32 can disengage from the limit hole 22. Then the user controls the lower bottom plate 3 to move toward the end away from the control groove 4, so that the connecting block 31 can move from the fixed groove to the connecting hole 21, thereby facilitating the control of the connecting block 31 to move out through the connecting hole 21, thereby realizing the separation of the lower bottom plate 3 and the upper bottom plate 2.

[0036] When installing a new sole, the user also controls the dial plate 33 to move downward to drive the limit block 32 to squeeze the first spring 36, so that the limit block 32 enters the moving groove 35, and then the connecting block 31 on the lower bottom plate 3 corresponds to the connecting hole 21 on the upper bottom plate 2, so that the connecting block 31 enters the connecting hole 21, and the lower bottom plate 3 is moved in the direction of the control groove 4, so that the connecting block 31 can enter the fixed groove, and the groove is used to limit the up and down movement of the connecting block 31. At this time, the limit block 32 and the limit hole 2 2, the user releases the paddle 33, the first spring 36 loses the external force restriction and returns to its original state and pushes the limit block 32 into the limit hole 22, so that the cooperation between the limit hole 22 and the limit block 32 is used to prevent the lower bottom plate 3 from moving in the horizontal direction, thereby realizing the quick connection and fixation of the upper bottom plate 2 and the lower bottom plate 3. After the lower bottom plate 3 is installed, the user closes the baffle 5, so that the slider 52 in the baffle 5 corresponds to the positioning hole on the control groove 4 to realize the closing of the baffle 5, thereby completing the replacement of the sole.
