Description

Technical Field

[0001] The utility model relates to the technical field of metal cutting, and particularly relates to an eye protection structure for a metal cutting face mask. Background Art

[0002] When a metal cutting machine cuts metal materials, the high-speed rotating cutter head will rub violently against the metal materials, thus generating sparks. Since the sparks splashing during the metal cutting process have a relatively high temperature and are easy to burn the skin, workers will wear a protective face mask to protect their faces. The protective face mask usually has a transparent eyepiece for observing the workpiece. However, due to the high brightness and glare of the sparks, after long-term use of the protective face mask with a transparent eyepiece, when workers look directly at the strong light for too long, it will cause great harm to their eyes. Therefore, the utility model proposes an eye protection structure for a metal cutting face mask to solve the above problems. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide an eye protection structure for a metal cutting face mask.

[0004] To solve the above technical problem, the utility model provides the following technical solutions:

[0005] An eye protection structure for a metal cutting face mask of the utility model includes a protective face mask, a headband arranged on the protective face mask, and an eyepiece frame arranged on the protective face mask. A protective lens is arranged on the eyepiece frame. Two connecting blocks are arranged on one side of the protective lens. Two fixing frames are arranged on one side of the eyepiece frame. The two connecting blocks and the two fixing frames are located in the same vertical horizontal plane. A connecting plate is arranged on the other side of the protective lens. A fixing block is arranged on one side of the eyepiece frame. The two connecting blocks are respectively rotatably connected to the two fixing frames. The connecting plate is designed in a "T" shape.

[0006] In an embodiment of the utility model, two connecting rods are arranged on one side of the protective lens. A spring is arranged outside the connecting rods. Fixing holes are formed in the connecting plate. Two through holes are formed on one side of the connecting plate. A fixing block is arranged on one side of the eyepiece frame.

[0007] In an embodiment of the utility model, the two connecting rods respectively penetrate through the two through holes, and the fixing block penetrates through the fixing holes.

[0008] In an embodiment of the utility model, an eyepiece lens is arranged inside the eyepiece frame. A card seat is arranged on one side of the eyepiece frame. A card slot is formed on one side of the card seat. A card block is arranged on one side of the protective lens.

[0009] In an embodiment of the present utility model, the objective lens is made of one of glass-structured lenses or acrylic-structured lenses, the protective lens is a glass-structured lens, and the protective lens is a smoked lens.

[0010] In an embodiment of the present utility model, both the card slot and the card block are designed in a "T" shape, and the card block is in clearance fit with the card slot.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By providing a protective lens, the present utility model can improve the protection effect on the eyes of workers. Since the sparks generated during the metal cutting process are very bright, and workers must closely monitor the workpiece when cutting metal workpieces to avoid cutting mistakes, it is impossible to avoid direct viewing of the sparks. The smoked lens can reduce the intensity of light entering the eyes, thereby reducing glare and playing a role in protecting the eyes;

[0013] At the same time, by providing a connecting block and a fixing frame, the protective lens can be rotated. When cutting a metal workpiece, the protective lens is rotated and fixed on the eyepiece frame to protect the eyes through the protective lens. When it is necessary to clearly observe the workpiece for fine cutting, the protective lens can be rotated and removed from the eyepiece frame, and the workpiece can be clearly observed through the objective lens.

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: an eye protection structure for a metal cutting face shield, including a protective face shield 10, a headband 20 provided on the protective face shield 10, and an eyepiece frame 30 provided on the protective face shield 10. The headband 20 is made of rubber and has elasticity for easy wearing of the protective face shield 10. A protective lens 40 is provided on the eyepiece frame 30. Two connecting blocks 4001 are provided on one side of the protective lens 40, and two fixing brackets 4002 are provided on one side of the eyepiece frame 30. The two connecting blocks 4001 and the two fixing brackets 4002 are located in the same vertical horizontal plane. A connecting plate 4005 is provided on the other side of the protective lens 40, and a fixing block 4008 is provided on one side of the eyepiece frame 30.

[0023] Among them, the two connecting blocks 4001 are respectively rotatably connected to the two fixing brackets 4002, and the connecting plate 4005 is designed in a "T" shape.

[0024] Meanwhile, two connecting rods 4003 are arranged on one side of the protective lens 40, a spring 4004 is arranged outside the connecting rod 4003, a fixing hole 4006 is formed on the connecting plate 4005, and the spring 4004 can be used to make the connecting plate 4005 automatically move downward, facilitating the automatic insertion of the fixing block 4008 into the fixing hole 4006. Two through holes 4007 are arranged on one side of the connecting plate 4005, and a fixing block 4008 is arranged on one side of the eyepiece frame 30.

[0025] In addition, the two connecting rods 4003 respectively penetrate through the two through holes 4007 to facilitate the up and down movement of the connecting plate 4005. The fixing block 4008 penetrates through the fixing hole 4006, and the fixing hole 4006 can play a role in limiting the fixing block 4008, facilitating the fixation of the protective lens 40 on the top of the eyepiece frame 30, and facilitating the worker to wear and use when cutting metal.

[0026] Please refer to Figure 4 , a lens 50 is arranged inside the eyepiece frame 30, a card seat 60 is arranged on one side of the eyepiece frame 30, a card slot 6001 is formed on one side of the card seat 60, and a card block 6002 is arranged on one side of the protective lens 40.

[0027] It should be emphasized that the lens 50 is made of one of the materials of a glass structure lens or an acrylic structure lens. The lens 50 is made of a transparent material, facilitating the worker to observe the workpiece being cut more clearly. The protective lens 40 is a glass structure lens, with high hardness and not easily damaged by sparks. The protective lens 40 is a smoked lens, and the smoked lens can reduce the light intensity entering the eyes, reduce glare, and can protect the worker's eyes, avoiding damage to the eyeballs caused by the worker looking directly at the high brightness of the sparks for a long time.

[0028] It can be understood that both the card slot 6001 and the card block 6002 are designed in a "T" shape, and the card block 6002 is in clearance fit with the card slot 6001, facilitating the limiting and fixing of the protective lens 40, and eliminating the need for the worker to always hold the protective lens 40 by hand to avoid arm soreness caused by the worker holding it for a long time.

[0029] Specifically, the working principle of the eye protection structure for a metal cutting face mask is as follows:

[0030] When in use, the protective face mask 10 can be worn on the face of the worker through the headband 20. Before cutting the metal workpiece, the protective lens 40 can be rotated and moved towards the side close to the eyepiece frame 30. At the same time, the connecting plate 4005 is pulled upwards. During this process, the spring 4004 is compressed. When the protective lens 40 fits with the eyepiece frame 30, the connecting plate 4005 is released. At this time, the connecting plate 4005 moves towards the side close to the fixing block 4008 under the action of the spring 4004, and the fixing block 4008 penetrates through the fixing hole 4006 to fix the protective lens 40. The protective lens 40 can reduce the light entering the eyes and lower the light intensity of the sparks, achieving the effect of protecting the eyes.

[0031] When the worker needs to clearly observe the metal workpiece for fine processing, first pull up the connecting plate 4005 to completely remove the fixing block 4008 from the fixing hole 4006, and rotate the protective lens 40 to move towards the side close to the protective face mask 10, facilitating the worker to clearly observe the workpiece to be cut through the eyepiece lens 50. During the process of rotating the protective lens 40, the clamping block 6002 can be pushed into the card slot 6001 to limit the protective lens 40, avoiding the need for the worker to fix the protective lens 40 by hand to prevent it from rotating and affecting the observation.

[0032] It should be noted that the specific model specifications of the protective lens 40 and the eyepiece lens 50 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0033] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "coaxial", "bottom", "one end", "top", "middle", "the other end", "up", "one side", "top", "inside", "front", "center", "both ends", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0034] In addition, the terms "first", "second", "third", "fourth" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first", "second", "third", "fourth" may explicitly or implicitly include at least one of such features.

[0035] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "swivel connection", etc. shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral body; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
