Description

Technical Field

[0001] This application belongs to the field of safety shoes, and particularly relates to a protective shell structure for safety shoes. Background Technology

[0002] Existing protective footwear is widely used in various high-risk work environments, such as industrial manufacturing, construction, and outdoor exploration, providing essential protection for workers' feet. These protective shoes typically employ a rigid protective structure to enhance resistance to risks such as impact injuries, punctures, and crushing.

[0003] However, existing protective shoe designs also have some problems. Because the protective structure and shoe are molded as a single piece, and because rigid materials are often used to ensure protective effectiveness, the comfort of the shoes during daily wear is severely affected. Therefore, existing protective shoes are largely limited to specific work environments and cannot meet the needs of users in their daily lives. This design limitation not only restricts the widespread application of protective shoes but also causes inconvenience for users when changing shoes in different situations. Therefore, it is necessary to solve the aforementioned technical problems. Summary of the Invention

[0004] The purpose of this application is to provide a protective shell structure for safety shoes to solve the technical problem of limited usage scenarios for safety shoes in the prior art.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a protective shell structure for safety shoes, comprising:

[0006] Base plate;

[0007] A fastener, forming a connecting part and a snap-fit ​​part, wherein the connecting part is connected to the edge of the base plate, and the snap-fit ​​part is connected to the side of the connecting part facing the base plate and is spaced apart from the base plate;

[0008] The containment shell has a snap-fit ​​edge that is detachably snapped between the snap-fit ​​portion and the base plate so that the containment shell, in conjunction with the base plate, forms a foot protection space.

[0009] Optionally, multiple fasteners are provided and evenly spaced along the edge of the base plate.

[0010] Optionally, the protective shell structure for the safety shoe also includes side panels;

[0011] The side guards are connected to the edge of the base plate and distributed on the front and rear sides of the fastener according to the edge direction of the base plate. The outer edge of the snap-fit ​​edge abuts against the side guards.

[0012] Optionally, the protective shell structure for the safety shoe also includes a rear flap connected to one of the side flaps closer to the heel;

[0013] The rear bumper and the side bumper are set at an angle, and the end face of the snap-fit ​​edge abuts against the rear bumper.

[0014] Optionally, the base plate has a first surface and a second surface that are stepped together, and a third surface that is arc-shaped and connected between the first surface and the second surface;

[0015] The first surface and the third surface are used to be embedded inside the target shoe body. The connecting part and the side guard of the fastener are both connected to the second surface. There is a gap between the connecting part and the side guard. The gap passes through the second surface and extends to the outer edge of the third surface.

[0016] Optionally, the base plate forms an avoidance notch in the portion between adjacent fasteners.

[0017] Optionally, a positioning slot is formed in the middle of one of the buckle portions located at the toe of the shoe, and a positioning protrusion that cooperates with the positioning slot is formed on the safety shell, and the positioning protrusion is connected to the snap-fit ​​edge.

[0018] Optionally, the top of the latch portion has a protrusion forming a lever.

[0019] Optionally, the outer wall of the lever piece is coplanar with the outer wall of the connecting portion, and the thickness of the lever piece is less than the length of the latching portion in the thickness direction of the lever piece.

[0020] The beneficial effects of the safety shoe protective shell structure provided in this application are as follows: Compared with the prior art, in the safety shoe protective shell structure provided in this application, the fasteners connected to the sole plate can detachably clamp the snap-fit ​​edge formed by the edge of the safety shell through the cooperation of their snap-fit ​​parts with the sole plate. In this way, during the safety shoe production process, only the sole plate can be integrated into the target shoe body. The safety shoe with the safety shell connected can form a foot protection space through the cooperation of the safety shell and the sole plate. Furthermore, after separating the safety shell from the sole plate, the safety shoe can be used for daily wear. This significantly expands the application scenarios of safety shoes and is far superior to the prior art. Attached Figure Description

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 9 as well as Figure 10 The present application provides a description of a protective shell structure for safety shoes. This protective shell structure includes a base plate 100, fasteners 200, and a safety shell 300. Wherein:

[0038] The fastener 200 forms a connecting portion 201 and a snap-fit ​​portion 202. The connecting portion 201 is connected to the edge of the base plate 100, and the snap-fit ​​portion 202 is connected to the side of the connecting portion 201 facing the base plate 100 and spaced apart from the base plate 100. The edge of the containment shell 300 forms a snap-fit ​​edge 301, which is detachably snapped between the snap-fit ​​portion 202 and the base plate 100 so that the containment shell 300 cooperates with the base plate 100 to form a foot protection space 400. In this embodiment, the connecting portion 201, made of elastic material, makes it easier for the snap-fit ​​edge 301 to be snapped between the snap-fit ​​portion 202 and the base plate 100.

[0039] According to the structure provided in this embodiment, in the protective shell structure for safety shoes provided in this embodiment, the fastener 200 connected to the base plate 100 can detachably clamp the snap-fit ​​edge 301 formed by the edge of the safety shell 300 through the cooperation of its snap-fit ​​part 202 with the base plate 100. In this way, during the safety shoe production process, only the base plate 100 can be integrated onto the target shoe body 1000. The safety shoe with the safety shell 300 connected can form a foot protection space 400 through the cooperation of the safety shell 300 and the base plate 100. After separating the safety shell 300 from the base plate 100, the safety shoe can be used for daily wear, which significantly expands the application scenarios of safety shoes and is far superior to the existing technology.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 3 to 8 Multiple fasteners 200 are provided and evenly spaced along the edge of the base plate 100. According to the structure provided in this embodiment, the multiple fasteners 200 provided along the edge of the base plate 100 can jointly clamp the snap-fit ​​edge 301, making the containment shell 300 more stably connected to the base plate 100. This is beneficial to further improve the connection stability between the containment shell 300 and the base plate 100 in this embodiment.

[0041] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 3 to 8 The safety shoe protective shell structure also includes side panels 500; the side panels 500 are connected to the edge of the base plate 100 and distributed on the front and rear sides of the fastener 200 according to the edge direction of the base plate 100, and the outer edge of the snap-fit ​​edge 301 abuts against the side panels 500. According to the structure provided in this embodiment, the side panels 500 connected to the base plate 100 can further maintain a stable relative position between the safety shell 300 and the base plate 100 by abutting against the outer edge of the snap-fit ​​edge 301, which is beneficial to further improve the connection stability between the safety shell 300 and the base plate 100 in this embodiment.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 3 to 8 The safety shoe protective shell structure also includes a rear guard 600 connected to a side guard 500 closer to the heel; the rear guard 600 is angled to the side guard 500 and the end face of the snap-fit ​​edge 301 abuts against the rear guard 600. According to the structure provided in this embodiment, the rear guard 600 can cooperate with the side guard 500 to limit the position of the safety shell 300 in two different directions, which can make the safety shell 300 maintain a more stable relative positional relationship with the base plate 100 and further improve the connection stability between the safety shell 300 and the base plate 100 in this embodiment; here, the base plate 100, fastener 200, side guard 500 and rear guard 600 are all integrally injection molded from TPU material.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 3 to 8 The sole plate 100 has a stepped first surface 101 and a second surface 102, and a third surface 103 connected between the first surface 101 and the second surface 102 in an arc shape. The first surface 101 and the third surface 103 are embedded inside the target shoe body 1000. The connecting part 201 and the side guard 500 of the fastener 200 are both connected to the second surface 102, and there is a gap 205 between the connecting part 201 and the side guard 500. The gap 205 penetrates the second surface 102 and extends to the outer edge of the third surface 103. In this way, the fastener 200 becomes a structure that can elastically fold outward under the action of external force and elastically return to its original position after the external force is removed. Furthermore, the connection structure of the connecting part 201 and the second surface 102 makes the path for elastic deformation longer, reducing the deformation stress of each part and helping to ensure the service life of the fastener 200. (See key reference) Figure 10 It is understandable that after being combined with the target shoe body 1000, the fastener 200, side panel 500, and rear panel 600 are all exposed outside the shoe upper. According to the structure provided in this embodiment, the sole plate 100, embedded inside the target shoe body 1000 via the first surface 101 and the third surface 103, and connected to the fastener 200 via the second surface 102, can form a more stable connection between the safety shell 300 and the sole plate 100, and facilitate the assembly and disassembly of the safety shell 300. This further improves the connection stability between the safety shell 300 and the sole plate 100 in this embodiment. In addition, the arc-shaped second surface 102 can eliminate stress concentration on the sole plate 100 caused by the target shoe body 1000, thereby facilitating a more stable connection between the sole plate 100 and the target shoe body 1000.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 3 to 8 The base plate 100 forms an avoidance notch 104 between adjacent fasteners 200. According to the structure provided in this embodiment, the avoidance notch 104 formed between adjacent fasteners 200 on the base plate 100 allows the target shoe body 10000 material to wrap around the base plate 100, thereby making the base plate 100 more stably attached to the target shoe body 1000. This is beneficial to further improve the installation stability of the safety shoe protective shell structure in this embodiment.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8A positioning slot 204 is formed in the middle of a buckle portion 202 located at the toe of the shoe. A positioning protrusion 302 that cooperates with the positioning slot 204 is formed on the safety shell 300. The positioning protrusion 302 is connected to the snap-fit ​​edge 301. Thus, when installing the safety shell 300, first align the positioning protrusion 302 at the front end of the safety shell 300 with the positioning slot 204 and insert it, so that the snap-fit ​​edge 301 on the safety shell 300 at that location enters the buckle portion 202 at the positioning slot 204 at an angle. Then press the safety shell 300 against the target shoe body 10000. In this way, the snap-fit ​​edges 301 on both sides of the safety shell 300 can accurately snap into the corresponding buckle portions 202, and the installation of the safety shell 300 can be completed quickly.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 The top of the latching part 202 has a protruding lever 203. With the above configuration, when it is necessary to remove the safety shell 300, the lever 203 is pulled outward to make the latching part 202 elastically flip outward and disengage from the latching edge 301, so that the safety shell 300 can be lifted up and flipped away, thereby making it easy to remove the safety shell 300.

[0047] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 The outer wall of the lever 203 is coplanar with the outer wall of the connecting part 201. The thickness of the lever 203 is less than the length of the snap-fit ​​part 202 in the thickness direction of the lever 203. In this way, on the one hand, the coplanarity of the outer wall of the lever 203 and the outer wall of the connecting part 201 helps to improve the consistency of appearance and enhance aesthetics. On the other hand, it also creates a gap between the lever 203 and the snap-fit ​​part 202, so that it can be operated by tools or by hand, which is convenient.

[0048] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
