Description

Technical Field

[0001] The utility model relates to the technical field of shoe soles, and specifically relates to a shoe sole with adjustable height. Background Art

[0002] For the structure of traditional shoe soles, after the height of the shoe sole is usually manufactured, the height of the shoe sole is fixed and cannot be adjusted flexibly. Or by using the method of pasting the heel, it is often easy to be lost due to insecure pasting. Based on this, the inventor studied and proposed this case. While ensuring that the height of the shoe sole is adjustable, the comfort during wearing is ensured. Summary of the Utility Model

[0003] The utility model provides a shoe sole with adjustable height, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0005] A shoe sole with adjustable height includes a shoe sole body and an adjusting block. A notch for installing the adjusting block is provided on the shoe sole body. A support cylinder is provided inside the adjusting block. The adjusting block is slidably installed on the notch, and a threaded rod is provided on the adjusting block. The threaded rod is threadedly connected to the adjusting block and the support cylinder. An airbag is further provided on the back side of the adjusting block. An air pipe is provided inside the shoe sole body. One end of the air pipe communicates with the airbag, and the other end extends to the outer side surface of the shoe sole.

[0006] A preferred technical solution: Two support cylinders are provided and symmetrically arranged on the back side of the adjusting block.

[0007] A preferred technical solution: Protrusions are provided on both sides of the adjusting block, and the protrusions slide along the inner side wall of the notch.

[0008] A preferred technical solution: One end of the air pipe extending to the outer side surface of the shoe sole is provided with a sealing plug, and the sealing plug is nested on the side surface of the shoe sole.

[0009] A preferred technical solution: Two air pipes are provided, which are divided into a first air pipe and a second air pipe. Check valves are provided on both the first air pipe and the second air pipe.

[0010] A preferred technical solution: The airbag is located between the two support cylinders.

[0011] A preferred technical solution: A threaded port for connecting the threaded rod is provided on the adjusting block.

[0012] A preferred technical solution: The screwing end of the threaded rod is in a shape of a cross or a plus sign.

[0013] A preferred technical solution: The screwing end of the threaded rod is a hexagonal port.

[0014] By adopting the above technical solutions, the beneficial effects of the utility model are as follows:

[0015] In the present utility model, the adjusting block can stably slide and adjust on the notch. By changing the relative height of the adjusting block in the vertical direction in the heel area of the sole, the height of the sole is changed; through the progressive movement of the thread, the position of the adjusting block is changed, and further, the airbag assists in supporting and adjusting on the back side of the adjusting block, so as to enhance the comfort of the heel area of the sole on the premise of meeting the adjustment requirements.

[0021] As Figures 1 - 2 shown, an adjustable-height sole includes a sole body 1 and an adjusting block 2. A notch 11 for installing the adjusting block 2 is provided on the sole body 1. A support cylinder 3 is provided inside the adjusting block 2. The adjusting block 2 is slidably installed on the notch 11, and a threaded rod 4 is provided on the adjusting block 2. The threaded rod 4 is threadedly connected to the adjusting block 2 and the support cylinder 3. An airbag 5 is further provided on the back side of the adjusting block 2. An air pipe 51 is provided inside the sole body 1. One end of the air pipe 51 communicates with the airbag 5, and the other end extends to the outer side of the sole. The material of the sole is mainly polyurethane material to ensure high comfort of the sole.

[0022] Furthermore, two support cylinders 3 are provided and symmetrically arranged on the back side of the adjusting block 2.

[0023] Furthermore, convex blocks 21 are provided on both sides of the adjusting block 2, and the convex blocks 21 slide along the inner side wall of the notch 11.

[0024] Furthermore, a sealing plug 52 is provided at one end of the air pipe 51 extending to the outer side of the sole, and the sealing plug 52 is nested on the side of the sole.

[0025] Further, two tracheas 51 are provided and are divided into a first trachea and a second trachea. One-way valves are provided on both the first trachea and the second trachea. The one-way valves can ensure the efficiency of gas injection during the gas injection process or the efficiency of gas extraction during the gas extraction process. During gas injection, the gas flow direction of the corresponding one-way valve is unidirectional from outside to inside; during gas extraction, the gas flow direction of the corresponding one-way valve is unidirectional from inside to outside. The structure of the one-way valve usually consists of a blocking ball, a blocking seat, a spring, and a gas passing plate structure. When the blocking ball is not affected by a force, the blocking ball does not compress the spring, and the blocking ball fits with the blocking seat. At this time, the valve body is in a closed state; on the contrary, when the blocking ball is affected by a force, the blocking ball compresses the spring, there is a gap between the blocking ball and the blocking seat, and gas enters the valve body and enters the other end through the gas passing plate.

[0026] Further, the airbag 5 is located between the two support cylinders 3.

[0027] Further, a threaded port 22 for connecting the threaded rod 4 is provided on the adjusting block 2.

[0028] Further, the screwing end of the threaded rod 4 is in a shape of a single slot or a cross slot.

[0029] Further, the screwing end of the threaded rod 4 is a hexagonal port.

[0030] During use, by screwing the threaded rod 4 with a corresponding screwdriver, the threads on the surface of the threaded rod 4 are progressively threaded with the adjusting block 2 and the support cylinder 3, changing the relative position of the adjusting block 2; the trachea 51 extends to a connection on the outer side of the sole to connect a corresponding air pump, so that gas is injected into the airbag 5 through the trachea 51, and the airbag 5 expands, which can assist in pushing out the adjusting block 2; after stopping gas injection, the sealing plug 52 is covered, and the airbag 5 can improve the buffering effect of the heel area of the sole.

[0031] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
