In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless specifically defined otherwise.

Referring to fig. 1-5, a screwless wide view bending telescope comprises: the spectacle frame 1 comprises a mounting frame 11 and a matching groove arranged on one side, close to a lens mounting surface, of the inner side of the mounting frame 11, wherein the matching groove comprises a top connecting groove 12 and a lateral connecting groove 13; the lens structure 2 comprises a lens 22 and clamping edges which correspond to the matching grooves one to one, wherein the clamping edges comprise a top clamping edge 21 matched with the top connecting groove 12 and a lateral clamping edge 23 matched with the lateral connecting groove 13; the side 3 of the glasses leg which is hinged with the side of the mounting rack 11 far away from the lens mounting surface; and a nose pad 4 clamped at the middle part of the bottom of the lens 22.

When the lens structure is installed, the top clamping edge 21 of the lens structure 2 is matched with the top connecting groove 12 firstly to complete the primary fixation between the two, then the lateral clamping edge 23 on one side is embedded into the lateral connecting groove 13, and then the lateral clamping edge 23 on the other side is embedded into the lateral connecting groove 13 on the other side, so that the fixed matching between the two is completed;

during disassembly, the steps are reversed, that is, the lateral clamping edges 23 on the two sides are removed, and then the top clamping edge 21 is removed from the top connecting groove 12.

In order to improve the degree of cooperation between lens structure 2 and mirror holder 1, be indispensable to the restriction of its degree of freedom in at least two directions, and in the degree of freedom at lens structure 2 top, its whole planar length that spans is longer, in order to improve holistic fixed strength, add protruding cooperation part down in its middle section part, it is specific:

top connecting groove 12 includes middle section connecting groove 121, and sets up separately middle section connecting groove 121 both sides and communicating vice connecting groove 122 correspond with it, the top joint along 21 include with the indent of middle section connecting groove 121 lock joint is along 211, and set up separately the indent along 211 both sides and with the evagination of vice connecting groove 122 lock joint is along 212, adopts such cooperation mode, can strengthen fixedly in the middle section part to 2 tops of lens structure, from this on the lens 22 of whole large-span, can provide a plurality of impetus, is favorable to lens 22's stable use.

In the above steps, the top fixing actually only serves as a positioning aid, and if the top fixing is adopted, the lens 22 cannot be fixed on the frame 1 at all, so the top fixing needs to be matched with the side fixing, and the specific matching manner is as follows:

the lateral connecting groove 13 comprises an inner fastening groove 131 extending along the inner side of the mounting frame 11 and communicating with the secondary connecting groove 122, and a lateral connecting groove 132 extending downwards along the inner fastening groove 131 away from the secondary connecting groove 122; a bent groove 133 communicated with the side connecting groove 132 and extended toward one side of the temple 3, correspondingly, the lateral clamping edge 23 includes an inner clamping edge 231 fastened in the inner fastening groove 131, a lateral clamping edge 232 extending downward along the bottom of the inner clamping edge 231 and fastened in the lateral connecting groove 132, a bent edge 233 connected with the lateral clamping edge 232 in an L-shape, wherein the engagement between the side coupling groove 132 and the side catching edge 232 is indispensable, providing the most basic restriction effect, and in order to enhance the restriction force in the lateral direction, wherein, the side upper end adopts an embedded inner clamping edge 231, the inner clamping edge 231 is embedded into the inner buckling groove 131 to complete the fixation of the upper half part, so that the whole lens structure 2 can not fall off, and at the lateral lower end, the bent edge 233 is buckled into the bent groove 133 through an L-shaped structure formed by the bent edge 233 and the side clamping edge 232. The entire lens 22 is constrained from the bottom by the corners of the L-shaped structure, completing the fixation of the lower half.

Through the cooperation of the above steps, on the outside of the whole lens 22, an inverted U-shaped buckling structure is actually formed, and the mirror bracket 1 also forms an inverted U-shaped matching structure, so that the lens structure 2 is fixed in the matching process of the mirror bracket 1 through the cooperation between the two structures without adopting fixing structures such as screws and the like.

There is some structure to adopt the mode of magnetism to inhale on the market, but adopts the structure of magnetism to inhale, will set up a plurality of magnetism and inhale the fixed point in fact, no matter be on lens structure 2 or mirror holder 1 on all need set up magnetism and inhale the point, and in case set up these fixed position backs, can inevitably lead to the fact the interference plane on whole mirror surface, can increase partly in user's field of vision and shelter from the area, is unfavorable for user's field of vision coverage.

In order to protect the whole lens structure 2 from the side, the bottom of the bent edge 233 is further connected with a side protection sheet 24 on the side wing of the lens structure 2, the extension radian of the side protection sheet 24 is flush with the unfolded radian of the glasses legs 3, and the free space area on the side of a user can be sealed in the wearing process of the user, so that the eyes of the user can be better protected, and the visual field of the user can be expanded by covering the lens material.

In order to improve the integration degree of the lens 22 and prevent the neutral zone and the connecting structure between the two mirror surfaces from affecting the viewing angle of the user, the lens 22 is an integrally molded structure of the two mirror surfaces.

The design of the nose pad 4 can be selected according to the user's requirement, and the nose pad 4 and the lens 22 can be integrally formed or detachably mounted, and can be selectively worn or not worn, and it is particularly emphasized that the nose pad 4 is made of the same material as the lens 22.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
