Description

Technical Field

[0001] This utility model relates to the field of footwear technology, and in particular to a high-density PU sole with massage and shock absorption functions. Background Technology

[0002] In daily life, the performance of insoles directly affects the comfort and practicality of wearing shoes.

[0003] Traditional insoles typically rely solely on the elasticity of the material itself for shock absorption, lacking a dedicated shock-absorbing structure design. When the foot is subjected to impact from the ground, they cannot effectively disperse and buffer the impact force. Long-term wear can easily cause fatigue in the feet and legs, and may even damage the joints. To solve the above problems, this application proposes a high-density PU sole with massage and shock absorption functions. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-density PU sole with massage and shock absorption functions. The ventilation holes at the toe and the ventilation grooves at the bottom work together to form an efficient airflow circulation channel, effectively dissipating foot sweat and preventing dampness, stuffiness, and odor, thus significantly improving wearing comfort. The honeycomb structure inside the insole interacts with the friction balls within the honeycomb holes to effectively disperse and cushion the impact force on the feet during walking, greatly reducing foot and leg fatigue and lowering the risk of joint damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-density PU sole with massage and shock absorption functions includes an insole and a shoe cover wrapped around the insole. The insole has multiple ventilation holes running through it. The top of the insole has multiple acupoint protrusions fixedly connected to it. The bottom of the insole has multiple protrusions fixedly connected to it and multiple ventilation channels. The insole has multiple honeycomb holes inside, each of which is filled with friction balls. The top of the insole has multiple massage protrusions fixedly connected to it.

[0007] Preferably, the ventilation holes are arranged in an array at the top of the insole, and the diameter of the ventilation holes is 1 to 3 mm.

[0008] Preferably, the height of the acupoint protrusion is 2 to 5 mm, and multiple acupoint protrusions are respectively set for the Yongquan acupoint, Taichong acupoint and Zulinqi acupoint on the human foot.

[0009] Preferably, the support part is made of high-density PU material, and the height of the support part is 1.2 to 1.5 times the overall height of the insole. The ventilation grooves are distributed in a Y shape on the support part.

[0010] Preferably, the honeycomb pores have a regular hexagonal structure, and the friction balls are made of elastic rubber material.

[0011] Preferably, the diameter of the friction ball is smaller than the inner diameter of the honeycomb pores.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The ventilation holes at the head and the ventilation channels at the bottom work together to form an efficient airflow circulation channel, which can dissipate foot sweat in time, effectively avoiding the problems of dampness, stuffiness and odor on the feet, and significantly improving the comfort of wearing.

[0014] 2. The acupoint protrusions are precisely designed to correspond to key acupoints on the human foot, which can provide appropriate stimulation to the acupoints during walking, thus fully exerting the massage and health care effects.

[0015] 3. The honeycomb structure inside the insole interacts with the friction balls inside the honeycomb holes, which can effectively disperse and cushion the impact force on the feet during walking, greatly reducing foot and leg fatigue and lowering the risk of joint injury.

[0016] In summary, the ventilation holes at the top and the ventilation channels at the bottom work together to form an efficient airflow circulation channel, which can effectively dissipate foot sweat in time, avoiding problems such as dampness, stuffiness and odor on the feet, and significantly improving wearing comfort. The honeycomb structure inside the insole and the friction balls inside the honeycomb holes interact to effectively disperse and cushion the impact force on the feet during walking, greatly reducing foot and leg fatigue and lowering the risk of joint injury.

[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 1-3 A high-density PU sole with massage and shock absorption function includes an insole 1 and a shoe cover 11 wrapped around the insole 1. The insole 1 serves as the basic structure of the entire sole, providing a mounting carrier for various components and supporting the foot. Multiple ventilation holes 2 are opened through the insole 1. The ventilation holes 2 can accelerate the air circulation of the foot and enhance the overall breathability in conjunction with the subsequent ventilation grooves 7. The ventilation holes 2 are arranged in an array at the head of the insole 1, and the diameter of the ventilation holes 2 is 1 to 3 mm.

[0023] The top of the insole 1 is fixedly connected with multiple acupoint protrusions 3. When walking, the acupoint protrusions 3 come into contact with the acupoints on the foot and produce a pressing effect to achieve a massage function. The height of the acupoint protrusions 3 is 2 to 5 mm, and the multiple acupoint protrusions 3 are respectively set to the Yongquan acupoint, Taichong acupoint and Zulinqi acupoint on the human foot.

[0024] The top of the insole 1 is fixedly connected to a support part 4. The support part 4 enhances the structural strength of the heel area and works with the insole 1 to distribute the force on the heel. The support part 4 has ventilation grooves 5, which further improve the air circulation at the heel and form a ventilation passage with the ventilation holes 2. The support part 4 is made of high-density PU material. The height of the support part 4 is 1.2 to 1.5 times the overall height of the insole 1. The ventilation grooves 5 are distributed in a Y shape on the support part 4.

[0025] The bottom of the insole 1 is fixedly connected with multiple protrusions 6, which increase the friction between the insole and the shoe upper. At the same time, they assist in shock absorption through deformation during walking. The bottom of the insole 1 has multiple ventilation grooves 7, which are connected to the ventilation holes 2 to form an airflow channel from the top to the bottom of the sole. The insole 1 has multiple honeycomb holes 8, which disperse the impact force through their own structure and improve the overall shock absorption performance of the shoe. Each honeycomb hole 8 is filled with friction balls 9. The friction balls 9 move slightly with the foot movement within the honeycomb hole 8, further buffering the vibration and enhancing the structural elasticity. The honeycomb hole 8 has a regular hexagonal structure, and the friction balls 9 are made of elastic rubber material. The diameter of the friction balls 9 is smaller than the inner diameter of the honeycomb hole 8. The top of the insole 1 is fixedly connected with multiple massage protrusions 10, which can massage the sole of the foot and relax the body.
