Description

Technical Field

[0001] This utility model relates to the field of durable shoe technology, and in particular to a durable shoe with a mortise and tenon structure. Background Technology

[0002] Durable shoes are footwear products designed for prolonged use and high-intensity environments. They typically offer greater abrasion resistance and improved comfort, suitable for situations requiring extended standing, walking, or exposure to significant pressure. Durable shoes generally utilize robust materials such as rubber, leather, and synthetic fibers, and their soles are designed for slip resistance and shock absorption to ensure the wearer's safety and comfort in various challenging environments. Therefore, durable shoes require a more robust construction than ordinary shoes to extend their lifespan and reduce the need for frequent replacements.

[0003] In practical use, existing durable shoe soles are typically fixed using an adhesive bonding process. As usage time increases, the strength of the adhesive gradually decreases, making the sole prone to detachment. This severely impacts the shoe's lifespan and safety, increasing the risk of falls and other safety hazards. Furthermore, repair costs are high, increasing maintenance inconvenience and expense. Additionally, adhesive-bonded soles are usually of a fixed height, unable to be flexibly adjusted to different usage scenarios or individual needs, often requiring the purchase of new shoes, and generally resulting in lower wearing comfort. Utility Model Content

[0004] Based on the technical problems of poor adaptability and difficulty in installing and replacing soles in existing durable shoes, this utility model proposes a durable shoe with a mortise and tenon structure.

[0005] This utility model proposes a durable shoe with a mortise and tenon structure, including a sole, an upper sewn to the top of the sole, a replacement sole at the bottom of the sole, and an installation component between the sole and the replacement sole. The installation component includes a shaped block, and the sole and the replacement sole are installed by inserting the shaped block.

[0006] Preferably, the mounting assembly further includes an upper groove formed at the bottom of the sole, and a lower groove formed at the top of the replacement sole, wherein the bottom surface of the sole fits against the top surface of the replacement sole.

[0007] The above technical solution utilizes separate design for the sole and replacement sole, facilitating easy replacement of the replacement sole, adapting to different occasions, and reducing maintenance costs while ensuring a stable connection.

[0008] Preferably, the two oppositely arranged irregularly shaped blocks are slidably connected within the upper and lower grooves on corresponding sides.

[0009] The above technical solution utilizes irregularly shaped blocks inserted into the upper and lower grooves to facilitate the connection between the shoe sole and the replacement sole.

[0010] Preferably, a positioning block is slidably connected to the top of the irregularly shaped block, and a sliding groove is provided on the bottom surface of the shoe sole.

[0011] The above technical solution utilizes a sliding groove to reserve a sliding position for the positioning block, which facilitates limiting the positioning block.

[0012] Preferably, a positioning bead is fixedly connected to the bottom surface of the sliding groove, and the positioning bead is matched with the positioning block.

[0013] The above technical solution uses a positioning bead, which is a small metal ball encased in plastic. The positioning bead is used to limit the position of the positioning block, making it easier to fix the positioning block.

[0014] Preferably, each of the two irregularly shaped blocks on one side has an insertion port, and a magnetic strip is slidably connected inside the insertion port.

[0015] With the above technical solution, the lower surface of the positioning block and the surface of the magnetic strip are both smoothly designed. The magnetic strip is inserted into the slot, which makes it easy to push the positioning block upward and engage with the positioning bead. The magnetic strip and the positioning bead are magnetically attracted to each other, which makes it easy to fix the positioning block and prevent displacement.

[0016] Preferably, both the sole and the replacement sole have annular grooves on their outer surfaces, and protective zipper strips are sewn together in opposite directions within the two annular grooves. A zipper head is fitted onto the protective zipper strip, and the teeth of the protective zipper strip engage with the zipper head.

[0017] The above technical solution utilizes the zipper head to close and protect the zipper strip, wrapping around and shielding the connection point to protect it and isolate it from dirt.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. By setting up the installation components, insert the irregular blocks from both sides of the upper and lower grooves, push the magnetic strip into the insertion port, and push the positioning block on the top of the irregular block upward. The positioning bead in the sliding groove of the shoe sole will be used for positioning and locking. The magnetic strip magnetically attracts the positioning bead to prevent the positioning block from shifting, which is convenient for installation and replacement. The connection is more secure and the cost of use is reduced. The positioning bead can also massage the sole of the foot.

[0020] 2. By setting up protective zipper strips and zipper heads, the zipper heads are used to close the protective zipper strips, which surrounds and covers the connection point, making it easy to protect the connection point and at the same time isolate dirt. Attached Figure Description
