The chemical-proof protective shoe has the advantages that on one hand, the ventilation assembly is installed between the puncture-proof insole and the vamp, so that when the chemical-proof protective shoe is worn and used, gas between the vamp and the protective lining is exhausted through the one-way exhaust valve by enabling the pressure bag to expand when a worker steps on the foot in the walking process, and the chemical-proof protective shoe is convenient to use; when the worker lifts the foot, the pressing bag recovers to the original shape, and meanwhile, the elastic connecting column recovers to the original shape, so that external air enters the space between the vamp and the protective lining through the one-way air inlet valve, and ventilation is repeated in this way, so that dryness of the interior of the protective shoe is ensured, and the comfort level of the worker when the protective shoe is worn is improved; on the other hand, by means of the design of the first flexible protection steel plate and the second flexible protection steel plate, the overall scratch and puncture prevention performance of the protection shoes is improved, and therefore the safety of the protection shoes is better during use.

Description

Technical Field

[0001] The utility model relates to the technical field of protective shoes, in particular to a pair of protective shoes that are resistant to chemicals. Background Art

[0002] When preparing chemical products in a chemical plant, in order to avoid damage to the workers' feet in the chemical product production site, the workers need to wear chemical-resistant protective shoes during the production process.

[0003] At present, the chemical-resistant protective shoes worn by workers in chemical plants are mainly composed of a non-slip sole, an insole installed on the top of the non-slip sole, and an integrated PVC upper formed on the insole. Although the chemical-resistant protective shoes of this structure can protect the workers' feet when used, on the one hand, the air permeability of the protective shoes themselves is poor. When the workers wear the protective shoes for a long time, the internal airtightness of the protective shoes is easily caused, resulting in the protective shoes being in a wet state for a long time, making the workers less comfortable during the wearing process. On the other hand, since the insole and upper of the chemical-resistant protective shoes of this structure are both flexible structures, they are easily scratched and punctured, resulting in poor safety of the protective shoes when used. Utility Model Content

[0004] (1) Technical issues to be solved

[0005] The technical problem to be solved by the present invention is to provide a chemical-resistant protective shoe that can realize the convenient exchange of gas inside and outside the protective shoe, ensure the dryness of the inside of the protective shoe, and improve the overall anti-scratch and puncture performance of the protective shoe in response to the current status of the existing technology.

[0006] (2) Technical solution

[0007] The present invention is realized through the following technical scheme: The present invention proposes a chemical-resistant protective shoe, comprising a puncture-proof insole, a shoe upper being installed on the upper side of the puncture-proof insole, the puncture-proof insole comprising an acid- and alkali-resistant pad layer and a flexible protective steel plate 1 installed in the acid- and alkali-resistant pad layer, a ventilation component being installed between the shoe upper and the puncture-proof insole, the ventilation component comprising a protective sleeve installed on the inner side of the shoe upper, air holes provided on the bottom and outer wall of the protective sleeve, an elastic connecting column installed between the outer wall of the protective sleeve and the inner wall of the shoe upper, pressure bags evenly distributed at the bottom end of the protective sleeve, a one-way air intake valve installed on one side of the top of the shoe upper, and a one-way exhaust valve installed on the other side of the top of the shoe upper, and a flexible protective steel plate 2 being installed at the toe part in the shoe upper interlayer.

[0008] Furthermore, a protective sole is installed at the bottom end of the puncture-proof insole, and the protective sole is bonded to the puncture-proof insole.

[0009] By adopting the above technical solution, the protective sole can ensure that the protective shoes have sufficient anti-slip performance when in use.

[0010] Furthermore, the upper, the protective lining and the acid- and alkali-resistant cushion layer are all made of PVC material, the protective sole is made of acid- and alkali-resistant rubber material, and the bottom of the protective sole has anti-slip grooves.

[0011] By adopting the above technical solution, the acid and alkali resistance of the shoe upper, the protective liner and the acid and alkali resistant cushion layer can be effectively ensured.

[0012] Furthermore, the protective sleeve is bonded to the shoe upper, and the ventilation hole passes through the protective sleeve.

[0013] By adopting the above technical solution, the vent holes can ensure that the gas in the protective bushing is easily discharged to the outside.

[0014] Furthermore, one end of the elastic connecting column is bonded to the shoe upper, and the other end of the elastic connecting column is bonded to the protective sleeve.

[0015] By adopting the above technical solution, when a worker wears the protective shoes and walks, the protective sleeve will move downward when the worker steps on the shoes, thereby driving the elastic connecting column to move downward.

[0016] Furthermore, the pressure bag is bonded to the protective bushing and the acid- and alkali-resistant cushion layer, and the pressure bag is a sealed balloon filled with gas.

[0017] By adopting the above technical solution, when the staff steps on the foot, the pressure bag is pressed to expand the pressure bag. After the pressure bag expands, the space between the shoe upper and the protective liner becomes smaller, so that the gas on the shoe upper is discharged to the outside through the one-way exhaust valve. When the staff lifts the foot, under the resetting action of the elastic connecting column and the pressure bag, the external gas enters the space between the shoe upper and the protective liner through the one-way air intake valve, thereby realizing ventilation inside the protective shoe.

[0018] Furthermore, the one-way air intake valve and the one-way air exhaust valve are both connected to the upper and the interior of the protective bushing.

[0019] By adopting the above technical solution, the one-way air inlet valve is mainly used to ensure that external air enters the protective shoe in one direction, and the one-way exhaust valve is mainly used to discharge the gas in the protective shoe to the outside in one direction.

[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In order to solve the problem that the chemical protection shoes currently worn by workers in chemical plants are mainly composed of non-slip soles, insoles installed on the top of the non-slip soles and an integrated PVC upper formed on the insole, although the chemical protection shoes of this structure can protect the workers' feet when used, on the one hand, the air permeability of the protective shoes themselves is poor. When workers wear them for a long time, the protective shoes are easily airtight, which causes the inside of the protective shoes to be in a wet state for a long time, making the workers less comfortable during the wearing process. On the other hand, since the insoles and uppers of the chemical protection shoes of this structure are flexible structures, they are easily scratched and punctured, resulting in poor safety of the protective shoes when used. By installing a ventilation component between the puncture-proof insole and the upper, the chemical-resistant protective shoe can be worn and used. When the worker steps on the foot while walking, the pressure bag can be expanded, so that the gas between the upper and the protective liner can be discharged through the one-way exhaust valve. When the worker lifts the foot, the pressure bag returns to its original shape, and at the same time, the elastic connecting column returns to its original shape, so that the outside air enters the space between the upper and the protective liner through the one-way air intake valve. The ventilation is repeated in this way, thereby ensuring the dryness of the inside of the protective shoe and improving the comfort of the worker when wearing the protective shoe. On the other hand, with the design of the flexible protective steel plate 1 and the flexible protective steel plate 2, the overall anti-scratch and anti-puncture performance of the protective shoe is improved, thereby making the protective shoe safer when in use.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figure 1-Figure 2 As shown, a chemical-resistant protective shoe in this embodiment includes a puncture-proof insole 2, a shoe upper 1 is installed on the upper side of the puncture-proof insole 2, the puncture-proof insole 2 includes an acid-resistant and alkali-resistant pad layer 201 and a flexible protective steel plate 202 installed in the acid-resistant and alkali-resistant pad layer 201, a ventilation component 4 is installed between the shoe upper 1 and the puncture-proof insole 2, the ventilation component 4 includes a protective bushing 403 installed on the inner side of the shoe upper 1, air holes 406 opened on the bottom and outer wall of the protective bushing 403, an elastic connecting column 404 installed between the outer wall of the protective bushing 403 and the inner wall of the shoe upper 1, pressure bags 405 evenly distributed at the bottom end of the protective bushing 403, a one-way air intake valve 401 installed on one side of the top of the shoe upper 1, and a one-way exhaust valve 402 installed on the other side of the top of the shoe upper 1, a flexible protective steel plate 25 is installed at the toe part of the interlayer of the shoe upper 1, and the flexible protective steel plate 202 is connected to the shoe upper 1. The combination of the flexible protective steel plate 25 improves the overall anti-scratch and puncture performance of the protective shoe. When the staff wears the protective shoe and walks, the protective sleeve 403 will move down when the staff steps on the foot, thereby driving the elastic connecting column 404 to move down. When the staff steps on the foot, the pressure bag 405 will expand. After the pressure bag 405 expands, the space between the upper 1 and the protective sleeve 403 will become smaller, thereby discharging the gas in the upper 1 through the one-way exhaust valve 402. When the staff lifts the foot, under the resetting action of the elastic connecting column 404 and the pressure bag 405, the external gas will enter the space between the upper 1 and the protective sleeve 403 through the one-way air intake valve 401, thereby realizing ventilation inside the protective shoe. The elastic connecting column 404 can also support the upper 1 when worn to prevent the upper 1 from deformation when the staff steps on the foot.

[0029] like Figure 1-Figure 2 As shown, in this embodiment, a protective sole 3 is installed at the bottom end of the anti-puncture insole 2, and the protective sole 3 is bonded to the anti-puncture insole 2. The protective sole 3 can ensure that the protective shoes have sufficient anti-slip performance when in use. The upper 1, the protective liner 403 and the acid and alkali resistant cushion layer 201 are all made of PVC, and the protective sole 3 is made of acid and alkali resistant rubber. The bottom of the protective sole 3 has anti-slip patterns, which can effectively ensure the acid and alkali resistance of the upper 1, the protective liner 403 and the acid and alkali resistant cushion layer 201.

[0030] like Figure 1-Figure 2As shown, in this embodiment, the protective sleeve 403 is bonded to the upper 1, and the air hole 406 passes through the protective sleeve 403. The air hole 406 can ensure that the gas in the protective sleeve 403 is easily discharged to the outside. One end of the elastic connecting column 404 is bonded to the upper 1, and the other end of the elastic connecting column 404 is bonded to the protective sleeve 403. The pressure bag 405 is bonded to the protective sleeve 403 and the acid and alkali resistant cushion layer 201. The pressure bag 405 is a sealed balloon filled with gas. The one-way air inlet valve 401 and the one-way exhaust valve 402 are both connected to the upper 1 and the interior of the protective sleeve 403. The one-way air inlet valve 401 is mainly used to ensure that external air enters the protective shoe in one direction, and the one-way exhaust valve 402 is mainly used for the one-way discharge of gas in the protective shoe to the outside.

[0031] The specific implementation process of this embodiment is as follows: when in use, the protective shoe is first put on the worker's foot, and the worker's foot is tightly fitted with the protective liner 403, and then the protective shoe can be put into use. During use, when the worker steps on his foot while walking, the pressure bag 405 is expanded, so that the gas between the upper 1 and the protective liner 403 is discharged through the one-way exhaust valve 402. When the worker lifts his foot, the pressure bag 405 returns to its original shape, and at the same time, the elastic connecting column 404 returns to its original shape, so that external air enters the space between the upper 1 and the protective liner 403 through the one-way air intake valve 401. The ventilation is repeated in this way to ensure the dryness of the inside of the protective shoe and improve the comfort of the worker when wearing the protective shoe. On the other hand, with the design of the flexible protective steel plate 1 202 and the flexible protective steel plate 2 5, the overall anti-scratch and puncture performance of the protective shoe is improved, thereby making the protective shoe safer when in use.

[0032] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
