Description

Installation component and protective glasses convenient to quick installation dismantles lens

Technical Field

The utility model relates to the technical field of protective glasses, in particular to a mounting assembly and protective glasses, wherein lenses are convenient to mount and dismount rapidly.

Background

Safety glasses are used to prevent smoke, wind sand, external impact, chemicals or optical radiation, etc. from damaging the eyes of the wearer, and these types of safety glasses are numerous, including windshields, snow goggles, etc.

Because the lenses of the goggles such as the goggles and the snowglasses are easily scratched by articles such as sand, branches and the like in the use process, the goggles are often scrapped in advance due to the fact that the lenses are scratched, namely the lenses form key factors for determining the service life of the goggles.

In order to solve the problem that the safety glasses cannot be used for a long time due to the short service life of the lenses, people want to make the lenses replaceable, so that when the lenses are scratched, the lenses can be replaced with new ones to continue to use the safety glasses without purchasing new ones again.

However, the prior protective glasses have complex connection structure of the lenses and the glasses frame, and complicated installation steps, so that the general users are reluctant to select the protective glasses with the replaceable lenses

Disclosure of Invention

In order to solve the problems of complex connection structure of the lenses and the frame of the common protective glasses with replaceable lenses, complicated installation steps and the like, according to one aspect of the utility model, an installation component convenient for rapidly installing and detaching the lenses is provided.

The mounting assembly for facilitating rapid mounting and dismounting of the lenses comprises a lens frame; and at least one clamping lever pivotably disposed on the frame; the clamping rod is also in clamping connection with the lens frame through a clamping structure, so that the clamping rod and the lens frame are in a clamping state for clamping the lens between the clamping rod and the lens frame, and an opening state for taking out the lens from the clamping rod and the lens frame; the clamping rod is also provided with a handle part.

Because the clamping rod is pivotally connected with the lens frame, and meanwhile, the clamping rod is also in clamping connection with the lens frame through the clamping structure, the clamping rod can realize the clamping connection of the clamping rod and the lens frame through the clamping structure in a mode of rotating relative to the lens frame, so that a lens is clamped between the clamping rod and the lens frame; the clamping structures of the clamping rods and the lens frame can be disassembled in a mode that the clamping rods rotate relative to the lens frame so as to release lenses clamped between the clamping rods and the lens frame; the clamping rod and the mirror frame can be clamped or opened through the rotation of the clamping rod, an external tool is not needed, the operation is convenient and quick, and the clamping rod is further provided with the handle part, so that an operator can realize the clamping connection or opening of the clamping rod and the mirror frame without using great force, and the operation is more labor-saving.

Therefore, when the handle part is pushed towards the side where the first opening is, the clamping part and the mirror frame can be opened, so that a certain angle is formed between the clamping part and the mirror frame, and at the moment, the lens can be taken out from the space between the clamping part and the mirror frame; moreover, because the handle portion sets up in the one side of deviating from first opening of the knot body, the operator of being convenient for adopts the mode of pushing the handle portion, realizes opening of clamping part and picture frame, and the operation is more convenient.

In some embodiments, a grip portion is provided with an anti-slip structure. Thus, the operator can use the handle portion more conveniently and stably. Preferably, the anti-slip structure is arranged on one side of the handle part, which is away from the first opening, so that the anti-slip structure can play a role in slip prevention when an operator pushes the handle part towards one side where the first opening is located.

In some embodiments, the non-slip structure is a protrusion or depression provided on an outer surface of the handle portion. Thus, the anti-slip function of the handle portion can be achieved by a simple structure.

In some embodiments, the clamping bars are provided in two and are located on opposite sides of the frame. Thereby, a stable lens clamping function can be achieved by only as few clamping bars as possible.

In order to solve the problems of complex connection structure of the lenses and the frame of the common protective glasses with replaceable lenses, complicated installation steps and the like, according to one aspect of the present utility model, a pair of protective glasses is provided.

The protective glasses comprise the mounting assembly which is convenient for rapidly mounting and dismounting the lenses; and a lens clamped between the frame and the clamping bar. Because can realize the block of clamping lever and picture frame through the rotation of clamping lever and be connected or open, need not with the help of external tool, convenient operation is swift, simultaneously, owing to still be provided with handle portion on the clamping lever for the operator need not to use very big strength just can realize the block of clamping lever and picture frame and be connected or open, and the operation is laborsaving swift.

In some embodiments, the mirror frame is also provided with a positioning part; the lens is also provided with a positioning hole matched with the positioning part. Therefore, when the lens is mounted on the lens frame, the positioning of the lens can be realized by sleeving the positioning hole of the lens on the positioning part of the lens frame.

In some embodiments, the frame includes a rigid frame and a sponge gasket disposed on a side of the rigid frame facing away from the lens; wherein, buckle structure sets up on hard frame. Thus, the lens can be stably supported through the hard frame, and the stability of the buckling structure can be kept; meanwhile, the sponge gasket is arranged on one side, away from the lenses, of the hard frame, so that wearing comfort can be improved.
