[0022] As shown in the figure, a steel toe cap for external wear on shoes includes a steel toe cap body 1, the steel toe cap body 1 has a protective plate 11 and a supporting bottom plate 12, the protective plate 11 is arc-shaped, and the supporting bottom is integrally formed at the lower end of the protective plate 11, and a supporting plate 2 in the shape of an arc is fixedly arranged in the steel toe cap body 1, a buffer cavity 3 is formed between the supporting plate 2 and the protective plate 11, and a tightening screw 4 whose end can pass through the buffer cavity 3 and the supporting plate 2 and extend into the interior of the steel toe cap body 1 is screwed on the side of the protective plate 11, an anti-slip protrusion 41 is formed on the end face of the tightening screw 4 extending into the interior of the steel toe cap body 1, and an operating handle 42 is integrally formed at the end of the tightening screw 4 located outside the steel toe cap body 1.

[0023] Specifically, two tightening screws 4 are symmetrically arranged.

[0024] Specifically, a buffer cushion layer 5 matching the buffer cavity 3 is disposed in the buffer cavity 3 , and two surfaces of the buffer cushion layer 5 are in contact with the protective plate 11 and the supporting plate 2 respectively.

[0025] Specifically, the structure in which the tightening screw 4 is screwed to the protective plate 11 is as follows: the protective plate 11, the buffer layer 5 and the supporting plate 2 are respectively provided with a first mounting hole 111, a second mounting hole 51 and a third mounting hole 21; the lower ends of the supporting plate 2 and the buffer layer 5 are pressed against the supporting bottom plate 12 to align the first mounting hole 111, the second mounting hole 51 and the third mounting hole 21; a T-shaped threaded sleeve 6 is passed through the third mounting hole 21 and the small end thereof passes through the third mounting hole 21, the second mounting hole 51 and the first mounting hole 111 in sequence; a retaining spring 61 is provided on the small end thereof which is tightly pressed against the outer surface of the protective plate 11, so that the large end of the threaded sleeve 6 is tightly pressed against the inner surface of the supporting plate 2; the tightening screw 4 is screwed into the threaded sleeve 6, and the above-mentioned tightening screw The structure arranged on the protective plate 11 by screwing and screwing the sleeve 6 enables the steel toe cap body 1, the buffer cushion layer 5 and the supporting plate 2 to be individually processed and formed and then assembled and fixed by the screwing sleeve 6, thereby facilitating the processing and forming of the steel toe cap body 1, the buffer cushion layer 5 and the supporting plate 2, and facilitating the individual replacement of the steel toe cap body 1, the buffer cushion layer 5 and the supporting plate 2, thereby extending the service life of the steel toe cap as a whole. In addition, in order to enhance the circumferential stability of the screwing sleeve 6 when it is inserted into the first mounting hole 111, the second mounting hole 51 and the third mounting hole 21, and to prevent the screwing sleeve 6 from rotating with the tightening screw 4, the screwing sleeve 6, the first mounting hole 111, the second mounting hole 51 and the third mounting hole 21 can be set as matching polygonal columns and polygonal holes, which will not be described in detail in this embodiment.

[0026] In the above embodiment, when wearing the steel toe cap, the steel toe cap is put on the head of the shoe so that the head of the shoe is extended into the supporting plate 2, and the bottom surface of the sole is placed on the supporting plate 12, and then the position of the steel toe cap is adjusted so that the steel toe cap can completely cover the head of the shoe, and then the tightening screw 4 is rotated inwardly so that the tightening screw 4 is tightly against the side of the sole. Through the action of the tightening screw 4, the steel toe cap can be well fixed when worn on the head of shoes of different sizes, thereby improving the stability of the steel toe cap when worn, facilitating people to walk when wearing the steel toe cap, and ensuring that the steel toe cap is kept on the head of the shoe to play a protective role, and the two symmetrically arranged tightening screws 4 can match each other. The protective plate 11 is tightly pressed against the side surfaces of the sole from two opposite directions, so that the steel toe cap can be worn more firmly on the head of the shoe, and since a buffer cavity 3 is formed between the protective plate 11 and the supporting plate 2, when the protective plate 11 is deformed by external impact or static pressure, the buffer space provides space for the deformation of the protective plate 11, and the supporting plate 2 separates the toes from the protective plate 11 to prevent the deformed protective plate 11 from directly squeezing the toes and causing damage to the toes, thereby improving the protective performance of the steel toe cap, and the buffer pad layer 5 arranged in the buffer space can absorb energy when the protective plate 11 is subjected to external impact or static pressure, thereby further improving the protective performance of the steel toe cap.

[0027] Preferably, the cushion layer 5 is made of polystyrene foam. Based on the characteristics of polystyrene foam, the cushion layer 5 has better energy absorption performance and reduces the mass of the cushion layer 5, thereby reducing the overall mass of the steel toe cap, making it more convenient to walk while wearing the steel toe cap.

[0028] Preferably, the support plate 2 is provided with a plurality of hollow grooves 22 to reduce the weight of the support plate 2 and the overall weight of the steel toe cap, making it more convenient to wear the steel toe cap and walk.

[0029] Furthermore, a plurality of strap rings 112 are fixedly connected to the outer surface of the protective plate 11 , a tensioning strap 7 is connected inside the strap rings 112 , and ends of a plurality of the tensioning straps 7 are fixedly connected to a fixing strap 8 .

[0030] Specifically, the tensioning strap 7 is an elastic strap, and the two ends of the fixing strap 8 are connected by Velcro.

[0031] In the above preferred embodiment, after the steel toe cap is worn on the toe of the shoe, the tightening strap 7 is tightened, and the fixing strap 8 loop 112 is fixed around the ankle. The steel toe cap is tightened backward and upward by tightening the tightening strap 7, so that the toe cap is more firmly kept on the toe of the shoe, which is convenient for walking when worn. The tightening strap 7 using an elastic band can adapt to the length of different shoes to tighten the steel toe cap. The fixing strap 8 at both ends is connected by Velcro, which makes it easy for people to fix the fixing strap 8 loop 112 around the ankle.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
