Abstract
Description
Technical Field
[0001] This utility model relates to the field of daily necessities technology, and in particular to a detachable and replaceable shoe. Background Technology
[0002] Most existing shoes have a fixed, one-piece upper and sole. However, in actual use, because the sole is in contact with the ground, the wear and tear on the sole is more noticeable than that on the upper. This often results in situations where the upper is relatively intact, but the sole is worn out, rendering the entire shoe unusable, causing a significant waste of resources. Furthermore, the fixed upper and sole design limits the application of shoes, making it difficult to replace the sole with a suitable one based on actual usage, thus hindering their usability. Utility Model Content
[0003] To address the technical problem of resource waste caused by the inconvenience of replacing existing shoe soles, this utility model proposes a detachable and replaceable shoe.
[0004] This utility model proposes a detachable and replaceable shoe, including a shoe body, with ventilation holes on the surface of the shoe body at the toe, and a sole mechanism installed on the lower surface of the shoe body. The sole mechanism includes a replaceable sole, with a front connecting strap and a rear connecting strap fixedly connected to the two ends of the replaceable sole, respectively. The rear connecting strap is located at the heel of the sole, and the front connecting strap is located at the toe of the sole.
[0005] Preferably, the surface of the front connecting strap has a locking seam, and a locking block is fixedly connected to the upper surface of the shoe body. The locking block is located on the surface of the ventilation hole, and the cross-section of the locking block is T-shaped.
[0006] The above technical solution utilizes a locking block to engage with the front connecting belt via a locking seam, thereby facilitating the installation and fixation of the front connecting belt while also allowing the front connecting belt to pull the locking block.
[0007] Preferably, both ends of the shoe body are fixedly connected with Velcro, and the adhesive ends of the two Velcro are fixedly connected to the end surfaces of the front connecting strap and the rear connecting strap, respectively.
[0008] The above technical solution uses Velcro to connect and fix the shoe body to the front and rear connecting straps, which facilitates the installation and fixation of the replacement sole. In order to increase the connection strength of the rear connecting strap, the Velcro at the rear of the shoe body can also be installed on the heel inside the shoe body, which facilitates the auxiliary clamping by the pressure of the human heel.
[0009] Preferably, an insert is fixedly connected to the lower surface of the shoe body, and the insert is made of polypropylene.
[0010] The above technical solution utilizes a rigid plastic material for the insert, which facilitates the insertion of the insert into the foot and allows for foot massage-like effects when the replaceable sole is not in use, by squeezing the sole of the foot with the insert.
[0011] Preferably, the upper surface of the replaceable sole is provided with a slot, and the inner wall of the slot engages with the surface of the insert block.
[0012] The above technical solution utilizes inserts and slots to increase the connection strength between the replaceable sole and the shoe body, thereby ensuring a firm connection between the replaceable sole and the shoe body.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. By installing a sole mechanism on the lower surface of the shoe body, the replaceable sole in the sole mechanism replaces the traditional one-piece structure of the shoe body and sole. This makes it easier to replace the sole with severe wear, thereby increasing the service life of the shoe, reducing resource waste, and allowing the sole to be replaced with different materials depending on the usage environment.
[0015] 2. By setting the front and rear connecting straps in the sole mechanism to connect and fix the shoe body to the replacement sole, it is easy to install and remove the replacement sole. At the same time, when the shoe body is in motion, the bending and stretching of the front connecting strap will drive the locking strap, which in turn will cause the toe of the shoe body to bulge, thereby promoting the breathability of the shoe body.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 A detachable and replaceable shoe includes a shoe body 1. A ventilation hole 2 is provided on the surface of the toe of the shoe body 1. A sole mechanism is installed on the lower surface of the shoe body 1. The sole mechanism includes a replaceable sole 3. A front connecting strap 31 and a rear connecting strap 32 are fixedly connected to the two ends of the replaceable sole 3, respectively. The rear connecting strap 32 is located at the heel of the sole, and the front connecting strap 31 is located at the toe of the sole.
[0023] By installing a sole mechanism on the lower surface of the shoe body 1, the replaceable sole 3 in the sole mechanism replaces the traditional one-piece structure of the shoe body 1 and sole. This facilitates the replacement of severely worn soles, thereby increasing the lifespan of the shoes, reducing resource waste, and allowing for the replacement of soles made of different materials according to different usage environments.
[0024] In order to fix the front end of the replaceable sole 3, a slot 33 is provided on the surface of the front connecting strap 31. A locking block 34 is fixedly connected to the upper surface of the shoe body 1. The locking block 34 is located on the surface of the ventilation hole 2. The cross section of the locking block 34 is T-shaped. The locking block 34 is used to lock with the front connecting strap 31 through the slot 33, so as to facilitate the installation and fixation of the front connecting strap 31, and at the same time, the front connecting strap 31 can pull the locking block 34.
[0025] To secure the rear end of the replaceable sole 3, Velcro 35 is fixedly connected to both ends of the shoe body 1. The adhesive ends of the two Velcro 35 are fixedly connected to the end surfaces of the front connecting strap 31 and the rear connecting strap 32, respectively. The Velcro 35 is used to connect and fix the shoe body 1 to the front connecting strap 31 and the rear connecting strap 32, thereby facilitating the installation and fixation of the replaceable sole 3. In order to increase the connection strength of the rear connecting strap 32, the Velcro 35 at the rear end of the shoe body 1 can also be installed at the heel on the inside of the shoe body 1, so as to facilitate the auxiliary tightening by the pressure of the human heel.
[0026] To fix the surface of the replaceable sole 3, an insert 36 is fixedly connected to the lower surface of the shoe body 1. The insert 36 is made of polypropylene. The use of the hard plastic material of the insert 36 makes it easy for the insert 36 to be inserted into the shoe body 1. When the replaceable sole 3 is not in use, the insert 36 can be used to press the sole of the foot, which can have a similar effect to foot massage. The upper surface of the replaceable sole 3 has a groove 37. The inner wall of the groove 37 is engaged with the surface of the insert 36. The insert 36 and the groove 37 increase the connection strength between the replaceable sole 3 and the shoe body 1, thereby making the connection between the replaceable sole 3 and the shoe body 1 firm.
[0027] By setting the front connecting strap 31 and the rear connecting strap 32 in the sole mechanism, the shoe body 1 and the replaceable sole 3 are connected and fixed, which makes it easy to install and remove the replaceable sole 3. When exercising, the bending and stretching of the front connecting strap 31 drives the buckle 34, which in turn drives the surface of the shoe body 1 at the toe to bulge, thereby promoting the breathability of the shoe body 1.
[0028] Working principle:
[0029] Before use, select a suitable replacement sole 3 as needed, splice the upper surface of the replacement sole 3 with the lower surface of the shoe body 1, so that the insertion hole is inserted into the slot 37 and snapped in place, and attach the front connecting strap 31 and the rear connecting strap 32 to the two Velcro straps 35 on the surface of the shoe body 1 respectively, and snap the front connecting strap 31 to the card block 34 through the card slot 33.
[0030] When in use, the movement of the foot causes the shoe body 1 and the replacement sole 3 to twist and deform. The pulling of the shoe body 1 and the replacement sole 3 causes the front connecting strap 31 to bend and straighten repeatedly. The deformation of the front connecting strap 31 pulls the locking block 34, and the locking block 34 causes the surface of the shoe body 1 to bulge, thereby bulging the air circulation inside the shoe body 1.
[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
