Detailed Description

In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.

Referring to fig. 1 to 4, an eyeglass with a wind tunnel includes a lens 1 and a lower frame 3, wherein the lower frame 3 is detachably disposed on the lower side of the lens 1; the upper part of the lens 1 is provided with a first wind tunnel 11, and the lower part of the lens 1 is provided with a second wind tunnel 12; the lower frame 3 shields the second wind tunnel 12.

From the above description, the beneficial effects of the utility model are as follows: through the design of the first wind tunnel 11 and the second wind tunnel 12 at the upper part and the lower part of the lens 1, the overall air permeability is high, and the lens 1 can be prevented from fogging, so that the personal safety is influenced; through the shielding of detachable lower frame 3 to second wind tunnel 12, on the one hand can change glasses style like switching between full frame and the half frame, on the other hand can adjust ventilative degree, also can dismantle in order to reduce facial bearing atress when lower frame 3 oppression face, improves the travelling comfort of wearing.

Further, a positioning protrusion 13 is provided at the lower part of the lens 1, and a positioning groove 32 adapted to the positioning protrusion 13 is provided in the lower frame 3.

As can be seen from the above description, the positioning protrusion 13 at the lower part of the lens 1 is matched with the positioning groove 32 of the lower frame 3, so that the lower frame 3 can be quickly positioned and installed after being disassembled.

Further, the lower frame 3 is provided with a bump 33 corresponding to the second wind tunnel 12 and engaged with the second wind tunnel.

As can be seen from the above description, the bump 33 of the lower frame 3 is engaged with the second wind tunnel 12, so as to shield the second wind tunnel 12 and improve the connection strength between the lower frame 3 and the lens 1.

Further, the device also comprises a nose bracket 4, wherein the nose bracket 4 is arranged in the middle of the lens 1, and the nose bracket 4 is clamped with the lower frame 3.

As can be seen from the above description, the connection between the lower frame 3 and the lens 1 is further enhanced by the clamping design of the nose bracket 4 and the lower frame 3, and the clamping design facilitates the quick disassembly of the lower frame 3.

Further, a socket 41 is arranged at one end of the nose bracket 4 close to the lower frame 3, and a bayonet 42 communicated with the socket 41 is arranged on the side surface of the nose bracket 4; one end of the lower frame 3 extends towards the socket 41 and is provided with a hook 31 matched with the bayonet 42.

As is clear from the above description, the fastening hook 31 of the lower frame 3 is inserted into the socket 41 of the nose bracket 4, and the bayonet 42 of the nose bracket 4 is fastened to the fastening hook 31 of the lower frame 3, so that the lower frame 3 and the nose bracket 4 are fixed.

Further, an adjustable nose pad 5 is arranged on the nose bracket 4.

As can be seen from the above description, the nose pad 5 is designed to be adjustable to a proper wearing angle by a user; and simultaneously, the possibility that the lower edge of the lens 1 presses the face can be reduced by combining the angle, the height and the opening (the distance between contact surfaces) of the nose pad 5.

Further, the lens further comprises an upper frame 2, and the upper frame 2 is detachably arranged on the upper side of the lens 1.

From the above description, the upper frame 2 serves as a main skeleton, and serves to connect the lens 1 and the temples.

Further, a first groove is formed in the upper portion of the lens 1, and a second groove is formed in the upper frame 2 corresponding to the first groove; the first and second grooves together form a first wind tunnel 11.

As can be seen from the above description, the complex process of directly forming the wind tunnel on the lens 1 can be reduced by forming the first wind tunnel 11 by combining the first groove of the lens 1 and the second groove of the upper frame 2.

Further, both sides of the lens 1 protrude from the upper frame 2 and the lower frame 3 in the length direction thereof.

As can be seen from the above description, the convex design on both sides of the lens 1 makes both sides of the lens 1 have no soft material or hard material wrapping, and the wind resistance is effectively reduced.

Further, the lower frame 3 is a soft material lower frame 3.

As can be seen from the above description, the design of the soft material lower frame 3 can reduce discomfort caused by pressing the face, has a certain buffering function and safety performance, is convenient to detach, and has high overall durability.
