Abstract
Description
Technical Field
[0001] The invention relates to an adjustable spectacle frame, in particular to an adjustable spectacle frame for a full-face gas mask. Background Art
[0002] There are many styles of dust and gas masks used by people now, including helmet type, hood type, filter type and other structures. According to the size of the mask and the different use environments, it is divided into full-face mask and half-face mask. When used in a toxic and harmful complex environment, a full-face gas mask is generally worn. The full-face gas mask has good sealing performance, can protect the human body well, and can be more effectively dust and gas. However, the full-face gas mask products on the market cannot be worn when the user wears glasses due to vision problems; the main reason is that the part where the full-face gas mask fits the face is sealed with silicone to prevent the outside poisonous gas from entering the mask and hurting the user, and when the user wears glasses and then wears the full-face gas mask, the temples on both sides of the mirror will destroy the sealing of the full-face gas mask and the face fitting part, so that the outside poisonous gas enters the mask and hurts the user, and in serious cases, it will also endanger life, so the existing full-face gas mask cannot be used for near / farsighted people, which seriously restricts the user population of the full-face gas mask. Therefore, it is necessary to design a kind of glasses frame that can be matched with full-face mask gas mask, allow myopia or hyperopia personnel also can use full-face mask gas mask, to solve the problem that above-mentioned full-face mask gas mask exists. Summary of the invention
[0003] The purpose of the present invention is to provide an adjustable frame for a full-face gas mask in view of the disadvantage that users of the existing full-face gas mask cannot wear glasses. The frame, adjustment device and bracket of the adjustable frame are independent detachable modules, which can be used for full-face masks of different models. After being installed inside the full-face mask, the frame can be adjusted in front and back and up and down distances according to the needs of the user, so as to completely solve the problem that myopic / hyperopic people cannot use the full-face gas mask.
[0004] The present invention achieves the above-mentioned purpose through the following technical solutions: An adjustable glasses frame for a full-face gas mask, which consists of a glasses frame, a bracket and an adjusting device, and is characterized in that the glasses frame is connected to the bracket through the adjusting device, the lower end of the bracket is plugged and fixed on the saddle-shaped boss at the bottom of the full-face gas mask through a U-shaped socket, and the bracket plug at the upper end of the bracket is plugged into the upper end fixing groove of the bracket at the upper part of the full-face gas mask.
[0005] The frame is composed of a frame body, a connecting boss and a lens. The connecting boss is arranged in the middle of the frame body, and a frame connecting opening through groove and a frame locking convex point are made on the connecting boss. The lenses are respectively installed on the frame bodies on both sides of the connecting boss.
[0006] The bracket is composed of a bracket body, a U-shaped socket and a bracket plug. The lower end of the bracket body is made with a U-shaped socket, and the upper end of the bracket body is connected to the bracket plug through a connecting base; the connecting base is equipped with a spring and a button and fixed by a buckle.
[0007] The adjusting device is a rectangular block with an adjusting hole formed on it and a T-shaped rack plug matched with the rack in the key formed at one end of the rectangular block.
[0008] The fixing groove at the upper end of the bracket is installed in the middle part of the upper end of the full-face gas mask and is fixed under the silicone sealing ring of the full-face gas mask.
[0009] The lenses are myopia lenses or aging lenses, and the degree of the lenses is selected according to the vision needs of the user.
[0010] The front-to-back distance between the frame and the bracket is adjusted through the adjustment hole on the adjustment device, and after the front-to-back distance is adjusted, it is fixed and locked by the frame locking protrusion; the upper and lower distances between the frame and the bracket are adjusted through the T-shaped rack plug at one end of the adjustment device and the rack matching the button, and after the upper and lower distances are adjusted, they are fixed and locked by the spring and the button.
[0011] Furthermore, the upper part of the connecting base to which the frame is connected through an adjusting device is provided with a mounting seat, and a fixing pin is made on the outer end of the mounting seat. The frame, the adjusting device and the connecting base are inserted into the fixing pin socket matched with the upper part of the inner surface of the full-face gas mask through the fixing pin on the mounting seat to fix the frame.
[0012] The beneficial effects of the present invention compared with the prior art are: The adjustable frame for the full-face gas mask enables nearsighted / farsighted people to wear and use the full-face gas mask for work by adding a frame with lenses and a supporting adjustment mechanism in the mask; and the frame and the bracket can be adjusted forward and backward and up and down according to the needs of the user, which can meet the needs of people with different head shapes and different vision. In addition, the assembly volume of the frame, the adjustment device, the fixed base, and the button is small, and by replacing different brackets, it can be adapted to full masks of different brands and models. It completely solves the problem that the full-face gas mask currently on the market cannot be worn and used when the user is nearsighted / farsighted, and the full masks of different brands and models need to be customized with special adjustable frames, resulting in a serious restriction on the user population of the full-face gas mask.
