Description

Technical Field

[0001] The invention relates to the field of daily necessities, and more precisely to safety shoes for nurses. Background Art

[0002] Anti-static conductive shoes are a kind of work shoes worn in dust-free workshops, advanced laboratories, and R&D centers of industries such as electronic semiconductor devices, electronic computers, anti-static shoes, electronic communication equipment, integrated circuits, and the pharmaceutical industry to reduce and eliminate the hazards of static electricity. In addition, such shoes are widely used in oil and gas development and storage management sites. Anti-static shoes can introduce static electricity from the human body into the earth, thereby eliminating static electricity on the human body. At the same time, they also effectively suppress the dust generated by people walking in the clean room, thereby achieving the anti-static and dust-proof effect of the dust-free purification workshop. Because the existing anti-static shoes conductors, the human body and the ground are easy to deviate, it also causes the overall inability to function.

[0003] Secondly, according to the national standard GB21148-2007 "Technical Requirements for Anti-static Shoes and Conductive Shoes", the resistance value of conductive shoes should be less than 100kΩ, and the resistance value of anti-static shoes should be 100kΩ~1000MΩ. Therefore, suitable shoes should be selected for different venues, so the existing ones are generally special shoes. In Chinese patent CN110859357A, named "A kind of anti-static shoe with translational switching", a shoe with a slide groove and a plurality of guide posts is disclosed, which switches the anti-static property and the insulating property by translating the guide posts. However, the applicant believes that the solution is too cumbersome in production, and the technical features of the solution are easily worn and damaged, resulting in a short service life of the product. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an anti-static conductive safety shoe for nurses. By superimposing different conductive material layers, the conductive layers can be conveniently switched to achieve safety protection purposes for different venues and situations.

[0005] To achieve the above object, the present invention provides the following technical solution: a nurse safety shoe, comprising a sole and an upper lining, characterized in that: it also comprises an inner shoe cover whose outer wall is tightly fitted with the sole and the upper lining, the inner shoe cover comprises an insole and an upper lining surface with a storage groove, the lower bottom surface of the insole is fitted with the sole, the upper lining surface is fitted with the upper lining, the insole and the upper lining surface cooperate to form a cavity for placing the foot, the insole is separated into an upper part and a lower part relative to the arch of the sole, and the upper part can be turned up and inserted into the storage groove;

[0006] The sole is also provided with a conductive rubber penetrating the sole, the upper part abuts against the conductive rubber, and a conductive wire A is provided at the abutting position of the two, and the conductive wire A penetrates the upper part to connect the conductive rubber and the cavity.

[0007] Through the above-mentioned scheme, the shoes are anti-static shoes in normal use. The upper part that can be separated from the left and right sides of the upper lining and only the front end is left connected is folded upward and inserted into the storage slot to achieve direct connection between the sole of the foot and the conductive rubber when worn, and used as conductive shoes. When used temporarily in an emergency, the wire A on the back of the upper part can be covered with the spare insulating tape attached to the lower part to block the connection between the conductive rubber 11 and the conductive wire A, thereby achieving insulating shoes.

[0008] As a further configuration of the present invention, the sole is further provided with a conductive cloth attached to the surface of the sole at the contact surface between the conductive rubber and the conductive wire A, and the conductive rubber is located in the middle and front of the sole relative to the Yongquan acupoint on the sole of the foot.

[0009] Through the above-mentioned arrangement, the conductive cloth can better realize the conduction between the inner cover of the shoe and the sole, and the conductive rubber which is harder than the sole material can also play a massage role.

[0010] As a further configuration of the present invention, it also includes a shoe rear strap with two ends hinged to the shoe upper lining, the shoe rear strap is movably arranged relative to the sole and the shoe upper lining and is a Velcro structure for convenient length adjustment.

[0011] Through the above-mentioned scheme setting, by utilizing the setting of the shoe back strap, it is convenient for the user to wear the shoes of this product, it is convenient for the user to adjust the size and comfort of the shoes, and it is convenient for the user to clean the inside of the shoes.

[0012] As a further configuration of the present invention, the outer surface of the upper lining is made of hard leather that is resistant to being punctured by sharp objects.

[0013] Through the above-mentioned scheme setting, in special working scenarios such as nurses and assembly line workers, the shoe upper lining is set to hard leather, which can effectively protect the feet from being injured by sharp objects such as tweezers, scissors, screwdrivers, etc. falling from the table or above the feet, and can also play a buffering role for blunt objects.

[0014] As a further configuration of the present solution, an insulating tape is further provided on the insole, and the insulating tape is larger than the size of the conductive wire A provided on the sole fitting surface.

[0015] As a further configuration of the present solution, the insulating tape is arranged on the bottom surface of the insole, the insulating tape is a removable tape and the tape surface is made of insulating material.

The safety shoes of this scheme can be used as anti-static shoes after the shoe inner cover is installed. In non-emergency situations, the style of the shoe inner cover can be replaced. The shoe inner cover made of the conductive wire A equivalent to the conductive shoe can be used as a conductive shoe. In case of emergency or temporary use, the inner shoe cover can be directly removed. If there is a low-voltage risk of leakage, in an emergency, the insulating tape made of the removable tape on the insole can be torn off and attached to the conductive wire A to cover the conductive wire A, thereby blocking the current path between the conductive wire A and the conductive rubber.

[0019] The technology of this solution is compared with the existing technical solution:

[0020] 1. This solution uses completely insulating materials to make the sole, equipped with an inner shoe cover with a detachable self-folding and storage insole, a sole and upper lining that can be used separately, and spare insulating tape, so that this product can be switched between conductive shoes and anti-static shoes. Furthermore, the insulating tape of the removable tape can be attached between the wire A and the conductive rubber to block and achieve insulation in a short period of time, and can be used as an insulating shoe in emergency situations;

[0021] 2. This solution uses a flexible conductive material similar to the material of shoes. The conductive rubber can be put in while the sole plastic is being made. The one-piece molding avoids gaps and cracking during use, thus increasing the service life of the product. At the same time, a retractable and completely detachable inner shoe cover is used to facilitate daily cleaning and maintenance.

[0022] 3. The shoes of this scheme are made of conductive cloth and conductive wire, which are soft enough not to cause discomfort to users, and are conducive to protecting the feet of users who stand and walk for a long time.

[0033] As a further configuration of the present invention, the sole 1 is further provided with a conductive cloth attached to the surface of the sole 1 at the contact surface between the conductive rubber 11 and the conductive wire A43. The conductive rubber 11 is located in the middle and front of the sole 1 relative to the Yongquan acupoint on the sole of the foot.

[0034] Through the above arrangement, the conductive cloth can better achieve electrical conduction between the shoe inner cover 4 and the sole 1, and the conductive rubber 11 which is harder than the sole 1 can also play a massage role.

[0035] As a further configuration of the present solution, an insulating tape 45 is further provided on the insole 41 , and the insulating tape 45 is larger than the size of the conductive wire A43 provided on the fitting surface of the sole 1 .

[0036] As a further configuration of the present solution, the insulating tape 45 is disposed on the bottom surface of the insole 41 . The insulating tape 45 is a removable tape and the tape surface is made of insulating material.

[0040] As a further configuration of the present invention, the outer surface of the upper lining 2 is made of hard leather that is resistant to being punctured by sharp objects.

[0041] Through the above-mentioned scheme setting, in special working scenarios such as nurses and assembly line workers, the shoe upper lining is set to hard leather, which can effectively protect the feet from being injured by sharp objects such as tweezers, scissors, screwdrivers, etc. falling from the table or above the feet, and can also play a buffering role for blunt objects.

[0042] As a further configuration of the present solution, the resistance value of the conductive rubber 11 is less than 100 kΩ, the resistance value of the conductive wire A43 is 100 kΩ to 1000 MΩ, and the remaining materials are highly insulating materials.

In emergency or temporary use, the upper part 411 of the insole 41 of the inner shoe cover 4 can be turned up and inserted into the storage groove 413. If it is a non-emergency, the style of replacing the shoe inner cover 4 can be adopted.
