Abstract

The utility model provides the concave lens structure of wide view field diving glasses. The front lens of the concave lens is plane, and the back lens is a concave lens. The concave lens structure is characterized in that the concave lens structure is suitable for the front lens of the wide view field diving glasses, the upper, the lower and the inner sides of the front lens are inner retractive embedded edges and can be embedded into the embedded groove of the glasses frame of the face shield, the other end is cut into the combination edge of the tangent plane, and the end lateral to the glasses surface is also cut into the combination edge of the tangent plane. When the front and the lateral lenses are combined into a wide view field diving glasses with the combination edge of the tangent plane, the front and the lateral lenses can not generate the frame edge blocking the sight line, and can formed the wide visual field and changeable diving short sight glasses.

Description

The concave lens structure of wide visual field water table mirror

Technical field

The utility model is relevant for the concave lens structure of a kind of wide visual field water table mirror, especially the near-sighted face mirror that refers to a kind of usefulness of diving under water, its according to the near-sighted wearer myopia number of degrees upper and lower, the inboard rim of removable forward eyeglass except having the embedding limit, another side cut into tangent plane in conjunction with the limit, this also cuts into the limit that combines of tangent plane in conjunction with limit and side direction eyeglass, the myopia that is combined into a wide visual field is during with the water table mirror, the visual field that can't influence surface mirror broadness.

Background technology

In fact three windows or four-light mouth diving mask on the market be subject to " edge " of device between front window and left and right window, and influence the visual field at present; Other has the dealer to create a kind of diving mask with wide visual field, announce (calling the preceding case of patent in the following text) No. 428576 as the TaiWan, China patent gazette, the forward eyeglass of case and side direction eyeglass are in the mode of viscose glue gummed before this patent, be combined into the minute surface of a forward and field of lateral vision, thereby make the structure of not having " longitudinal framing " between the front window of diving mask and side window; Because this just, the side direction eyeglass is with the sticking dead mode combination of viscose glue, must change the myope of concave lens so can't be applicable to near-sighted number of degrees difference and wear.

In view of this, this journey experience for many years is engaged in the utility model people accumulation, is study intensively and test improvement repeatedly, nowadays sample is finished and has been manufactured in creation finally, a kind of concave lens of novel wide visual field water table mirror is provided, can overcomes the shortcoming of traditional product, to promote effect.

Novel content

Fundamental purpose of the present utility model is to provide the concave lens structure of a kind of wide visual field water table mirror, the also different forward eyeglass of lens thickness by near-sighted number of degrees difference, its upper and lower, inboard formed embedding limit can embed in the formed caulking groove in face shield picture frame architrave limit, the other end cut into tangent plane in conjunction with the limit, be the water table mirror that the limit is combined into a wide visual field that combines with side direction eyeglass one end grain.

Its concrete structure is: the concave lens structure of a kind of wide visual field water table mirror, the front eyeglass of this concave lens is a flat face, back side eyeglass is concavees lens, it is characterized in that: by the formed forward eyeglass of concave lens, on it, downside and in contract in the side-line and be arranged with into the embedding limit, the formed caulking groove of this embedding limit shape and embeddable silica gel face shield picture frame architrave limit coincide mutually, the forward eyeglass other end is not provided with the embedding limit, and cut into tangent plane in conjunction with the limit, side direction eyeglass one end also cut into tangent plane in conjunction with the limit, the forward eyeglass mutually is abutted against combination in conjunction with the limit with the limit that combines of side direction eyeglass with it.

Understand in order to allow the auditor that the utility model is had further, Zi Zuo is described in detail as follows with graphic:

Fig. 5: the utility model just, the plane of side direction eyeglass is in conjunction with figure.

Embodiment

See also Figure 1 and Figure 2, the utility model is embodiment with the water table mirror of double window mouth (bimirror face); The main component compositions such as face shield 2, two glass-mirrors 3 and two hard eyelets 4 that formed by rigid plastic frame molding framework 1, soft silica gel form, wherein face shield 2 is nested with in framework 1 inboard, two minute surfaces 3 frame are respectively put in face shield 2 formed two picture frames 21, two eyelets 4 are embedded in respectively on two minute surfaces 3, and left and right two minute surfaces 3 are made up of forward eyeglass 31 and side direction eyeglass 32 respectively, it is characterized in that:

Consult shown in Figure 3, the front eyeglass of concave lens is that flat face, a back side eyeglass is concavees lens, wear for cooperating myope, its thickness is according to the different forward eyeglass 31 of the number of degrees of myopia, its upper and lower side and in contract in the side-line and be arranged with into L shaped embedding limit 311, this embedding limit 311 utilizes embedding limit 311 to embed in the caulking groove 211 (as Fig. 2) in order to cooperate the formed L shaped caulking groove 211 in two picture frames, 21 architrave limits of silica gel face shield 2, and forward eyeglass 31 is embedded in the picture frame 21; Forward eyeglass 31 other ends do not have the embedding limit, the system cut into tangent plane in conjunction with limit 312, side direction eyeglass 32 1 ends that combine with forward eyeglass 31 also cut into tangent plane in conjunction with limit 321, and just, the having elasticity in conjunction with limit 312,321 with monolateral or bilateral coating or applying last layer and combine (as Fig. 4 and Fig. 5) of

side direction eyeglass

31,32 with the medium of thickness or in the bonding mode of viscose glue, this faying face is less to the sight line influence of using.

In addition, framework 1 is provided with a caulking groove 11 in picture frame 21 sides, this caulking groove 11 is to be made of one piece or with the assembling mode moulding, locate for side direction eyeglass 32 rear sides, forward eyeglass 31 is with in conjunction with limit 312 abutting against in conjunction with limit 321 with side direction eyeglass 32, when eyelet 4 masks just, side direction eyeglass 31, in the time of on 32, forward eyeglass 31 inside and outside urgent side direction eyeglasses 32, press into the structure of a driving fit sealing, and be combined into the water table mirror in the wide visual field of double window mouth, because the utility model just,

side direction eyeglass

31,32 do not have the edge of obstructing the view, so the visual field is considerably broad.

In sum, the concave lens structure of the wide visual field of the utility model water table mirror, by improving the concave lens of the wide visual field of traditional type water table mirror front end, be designed to the tool tangent plane in conjunction with the limit just, the side direction concave lens, just, when the side direction eyeglass is combined into the water table mirror in the wide visual field, owing to there is not the edge of obstruct the view, so visual field person that can't influence surface mirror broadness, its practical effect is when unquestionable, and the utility model is never made the city know or seen other books and periodicals document, the regulation that meets Patent Law is filed an application then in accordance with the law.
