Description

Technical Field

[0001] This utility model relates to the field of safety shoes, specifically to a safety shoe with a modular puncture-resistant sole. Background Technology

[0002] Safety shoes are widely used in many fields such as industrial production, construction, and logistics transportation, serving as essential equipment to ensure the safety of workers' feet. Traditional safety shoes typically employ a one-piece structure, with the sole and upper fixed by adhesive or stitching.

[0003] Over time, adhesive bonding can lose its stickiness due to wear, aging, or chemical corrosion, causing the sole to separate from the shoe body and affecting the normal use of safety shoes. While stitching is relatively secure, the disassembly and reassembly process is extremely complicated when the sole is severely worn and needs to be replaced. It often requires specialized tools and personnel, consuming a lot of time and effort.

[0004] Furthermore, regardless of the method, once the sole is damaged, the entire safety shoe faces the dilemma of being scrapped or difficult to repair, which not only wastes resources but also increases the cost of use. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned defects and provide a modular puncture-resistant safety shoe, thus solving the existing technical problems.

[0006] The objective of this utility model is achieved through the following means:

[0007] A modular puncture-resistant safety shoe includes a shoe body, a puncture-resistant sole with an inner steel plate lining on the lower end surface of the shoe body, a metal toe cap on the toe of the shoe body, three L-shaped limiting blocks sewn and fixed at equal intervals inside the lower end surface of the shoe body, three equally spaced top grooves on the upper end surface of the puncture-resistant sole, a limiting plate fixedly installed on one side of the upper end of the top groove, and the limiting plate is adapted to the L-shaped limiting blocks, a tail block sewn and fixedly installed at the rear of the shoe body, an inner groove on the lower end of the tail block, a return spring and a limiting baffle installed sequentially from top to bottom inside the inner groove, and a lever fixedly installed on the outer side of the upper end surface of the limiting baffle.

[0008] Furthermore, the metal toe is stitched and fixed to the shoe body, and the limiting baffle is slidably connected to the inner groove, with the inner groove restricting the movement trajectory of the limiting baffle.

[0009] Furthermore, an anti-slip strip is provided on the outer side of the lever, and the anti-slip strip is fixedly connected to the lever. The anti-slip strip is used to improve the anti-slip performance of the lever.

[0010] Furthermore, a spring is embedded in the upper end of the L-shaped limiting plug, and a limiting strip is fixedly provided on the top of the spring, which enables the limiting strip to automatically reset.

[0011] Furthermore, a limiting groove is formed on the lower end face of the limiting plate, and the limiting strip is adapted to the limiting groove.

[0012] Furthermore, a side groove is provided inside the metal toe on the side near the puncture-resistant sole, and an insert is fixedly provided at the end of the puncture-resistant sole near the metal toe, and the side groove and the insert are adapted to each other. The insert is inserted into the side groove so that the puncture-resistant sole can be easily aligned and connected with the metal toe.

[0013] The beneficial effects of this utility model are:

[0014] This invention achieves rapid and precise positioning and connection between the puncture-resistant sole and the shoe body by equidistantly stitching L-shaped limiting blocks inside the lower end face of the shoe body, and by creating a top groove inside the upper end face of the puncture-resistant sole with an inner steel lining that matches the L-shaped limiting blocks, and installing a limiting plate within the top groove. A limiting structure consisting of a return spring, a limiting baffle, and a lever installed inside the tail block provides stable positioning and easy disassembly of the puncture-resistant sole. This modular design offers the advantages of easy installation and quick disassembly, greatly improving the efficiency of replacing puncture-resistant soles; it solves the technical problems of existing safety shoes, such as difficult sole replacement, high maintenance costs, and inability to flexibly adapt to different working environments.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. This embodiment refers to... Figures 1-4 The present invention relates to a modular puncture-resistant safety shoe with a puncture-resistant sole, comprising a shoe body 1, a puncture-resistant sole 2 with an inner steel plate on the lower end of the shoe body 1, a metal toe cap 3 on the toe of the shoe body 1, three L-shaped limiting blocks 10 being sewn and fixed at equal intervals inside the lower end of the shoe body 1, three equally spaced top grooves 7 being opened inside the upper end of the puncture-resistant sole 2, a limiting plate 8 being fixedly installed on one side of the upper end of the top groove 7, and the limiting plate 8 being adapted to the L-shaped limiting blocks 10, a tail block 4 being sewn and fixed at the tail of the shoe body 1, an inner groove 13 being opened at the lower end of the tail block 4, a return spring 15 and a limiting baffle 14 being installed sequentially from top to bottom inside the inner groove 13, and a lever 16 being fixedly installed on the outer side of the upper end of the limiting baffle 14.

[0021] like Figure 2 and Figure 4 As shown, the metal toe 3 is stitched and fixed to the shoe body 1, and the limiting baffle 14 is slidably connected to the inner groove 13, with the inner groove 13 restricting the movement trajectory of the limiting baffle 14.

[0022] like Figure 2 and Figure 4 As shown, an anti-slip strip 17 is provided on the outer side of the lever 16, and the anti-slip strip 17 is fixedly connected to the lever 16. The anti-slip strip 17 is used to improve the anti-slip performance of the lever 16.

[0023] like Figure 2 and Figure 3 As shown, the upper end of the L-shaped limiting plug 10 is embedded with a spring piece 11, and the top of the spring piece 11 is fixedly provided with a limiting strip 12, which enables the limiting strip 12 to have automatic reset capability.

[0024] like Figure 2 and Figure 3 As shown, a limiting groove 9 is provided on the lower end face of the limiting plate 8, and the limiting strip 12 is adapted to the limiting groove 9.

[0025] like Figure 1 and Figure 2 As shown, a side groove 5 is provided inside the metal toe 3 on the side near the puncture-resistant sole 2. An insert 6 is fixedly provided at the end of the puncture-resistant sole 2 near the metal toe 3, and the side groove 5 and the insert 6 are adapted to each other. The insert 6 is inserted into the side groove 5 so that the puncture-resistant sole 2 can be easily aligned and connected with the metal toe 3.

[0026] The working principle of a modular puncture-resistant safety shoe with a puncture-resistant sole in this embodiment is as follows: When installing the puncture-resistant sole 2, first pull the lever 16 upward so that the limiting baffle 14 is retracted into the inner groove 13, so that the upper end face of the puncture-resistant sole 2 is attached to the lower end face of the shoe body 1, and the top groove 7 is aligned with and merged with the L-shaped limiting insert 10. Then, move the puncture-resistant sole 2 toward the head of the shoe body 1 so that the L-shaped limiting insert 10 is combined with the limiting plate 8. At this time, the limiting strip 12 at the lower end of the spring piece 11 is combined with the limiting groove 9 of the limiting plate 8.

[0027] Release the lever 16, and the reset spring 15 pushes the limit baffle 14 so that it extends out of the inner groove 13 and blocks the puncture-proof sole 2, thereby making the installation of the puncture-proof sole 2 more stable.

[0028] When disassembling the puncture-resistant sole 2, first pull the lever 16 to remove the obstruction of the limiting baffle 14 from the puncture-resistant sole 2, then pull the puncture-resistant sole 2 toward the tail block 4 to separate the limiting plate 8 from the L-shaped limiting insert 10, and then move it downward to remove the puncture-resistant sole 2. This method makes it easy to replace the sole.

[0029] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
