Description

Technical Field

[0001] The utility model relates to the technical field of safe production, in particular to a safe production protective mask. Background Art

[0002] A mask refers to a covering that covers all or part of the face and has holes for the eyes. It is usually used as a disguise and protective cover for dances, carnivals or similar festivals, dramas, etc. Mask culture is also commonly known as Nuo culture, and masks are usually needed for protection in production.

[0003] Publication number CN215916260U discloses a chemical safety protective mask, which relates to the field of chemical protection technology. The mask comprises a housing, the front of which is fixedly connected to a breathing filter, the top of which is fixedly connected to a transparent mirror, and the back of which is provided with two symmetrical left and right protective mechanisms. The two groups of protective mechanisms comprise an inclined frame, a spring rod, a cushion, a first push plate, a folding rod, a pull plate, a tension spring, a parallel rod, a two-way plug, a semicircular plate, a reversing rod, a second push plate, and an airbag. Compared to traditional protective masks, this protective mask can automatically seal the breathing filter and clean particles attached to the interior of the protective mask, preventing toxic substances in the air from infecting the breathing filter and improving the wearing comfort of the protective mask. However, the existing device still has some shortcomings. The style of the existing device is relatively fixed, and it needs to be put on the head during wearing. Although it is more convenient when moving, it will feel stuffy and uncomfortable when worn for a long time. For protection in a certain fixed position, a fixed protective mask can be made to reduce the burden on the wearer and make operation more convenient. In addition, the adjustment mechanism of the existing device is insufficient. It is inconvenient to adjust the fixed protective mask to the appropriate height for people of different heights, so as to achieve a good protective effect. For this reason, we propose a safe production protective mask to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 The utility model provides an embodiment: a production safety protective mask, comprising a protective mask body 1, an adjusting mechanism 2 is provided at the bottom end of the protective mask body 1, and a fixing mechanism 3 is provided at the bottom end of the protective mask body 1;

[0025] The adjustment mechanism 2 includes a first connecting rod 210, which is fixed to the bottom end of the protective mask body 1, a second connecting rod 220 is provided on the surface of the first connecting rod 210, a third connecting rod 230 is inserted into the interior of the second connecting rod 220 through a bearing, a rotating block 240 is fixed to the bottom end of the third connecting rod 230, a first fixing block 250 is fixed to the surface of the second connecting rod 220, and a second fixing block 260 is fixed to the bottom end of the first fixing block 250, a third fixing block 270 is provided on the surface of the second fixing block 260, and a fourth fixing block 280 is fixed to the bottom end of the third fixing block 270;

[0026] The fixing mechanism 3 includes a fixing plate 310 , which is fixed to the surface of the third fixing block 270 , and a fixing bolt 320 is inserted into the interior of the third fixing block 270 ;

[0027] The two sides of the protective mask body 1 are curved and angled. When debris bounces onto the protective mask body 1, the structure of the protective mask body 1 prevents the debris from rebounding toward the user during the secondary rebound, thereby improving user safety. The middle part of the protective mask body 1 is made of transparent acrylic material, which facilitates observation through the protective mask body 1.

[0028] The first connecting rod 210 has a square structure. The first connecting rod 210 is inserted into the interior of the second connecting rod 220. The surface of the third connecting rod 230 is provided with a thread. The interior of the first connecting rod 210 is provided with a threaded hole adapted to the first connecting rod 210. The third connecting rod 230 is inserted into the interior of the first connecting rod 210. The square structure of the first connecting rod 210 allows the second connecting rod 220 to limit the first connecting rod 210, so that the first connecting rod 210 can move up and down under the rotation of the third connecting rod 230 to adjust the height of the protective mask body 1;

[0029] The height of the first fixed block 250 is 12 cm, and the rotating block 240 is arranged on the inner side of the first fixed block 250, which is convenient for the hand to reach into the inner side of the first fixed block 250 to rotate the rotating block 240. Sliders are provided on both sides of the second fixed block 260, and the interior of the third fixed block 270 is provided with a slide rail adapted to the slider. The second fixed block 260 is inserted into the interior of the third fixed block 270, so that the protective mask body 1 is smoother when moving laterally and is convenient for adjustment. A groove is provided inside the fourth fixed block 280, and the width of the fourth fixed block 280 is greater than that of the third fixed block 270, so that the fourth fixed block 280 can be used for storage. The width of the fourth fixed block 280 is greater than that of the third fixed block 270, which makes it more convenient to take things.

[0030] Working principle: When the device is working, during safe production, when protection is needed at a certain point, the fixing plate 310 can be clamped on the workbench, and then the fixing plate 310 can be fixed with the fixing bolt 320 so that the third fixing block 270 can be fixed on the edge of the desktop, and then the face is placed behind the protective mask body 1 to protect and work at the same time. When the position of the protective mask body 1 needs to be adjusted, the protective mask body 1 can be adjusted laterally by pushing the protective mask body 1 laterally, and the rotating block 240 is rotated so that the first connecting rod 210 can move up and down, so that the protective mask body 1 can move up and down, and the height of the protective mask body 1 is adjusted so that the protective mask body 1 can fit the position of the face more closely. The setting of the fixed protective mask body 1 makes the user more relaxed and will not cause discomfort due to wearing for too long. It is suitable for long-term use. At the same time, in an emergency, since it can be fixed to the edge of the workbench by the fixing plate 310 and the fixing bolt 320, the installation of the device is more flexible and suitable for different positions. The above is the entire working principle of the present utility model.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
