Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a protective cover body and protective glasses. Background Art

[0002] In order to further reduce the gap between the protective ring and the user's face and reduce the invasion of fine particles (such as pollen, dust, and droplets) into the eyes, existing protective glasses are additionally provided with a silicone cover. Most existing silicone covers are double-layer structures that conform to the edge of the protective ring and are fixed by putting the double-layer structure on the outside of the protective ring.

[0003] However, the existing silicone cover has the following technical defects in actual use:

[0004] 1. In order to avoid the connection part of the glasses legs during installation, the silicone cover body is usually reserved with gaps on both sides of the outer ends to avoid it. The main body and the protective ring of the glasses are only fixed by the upper and lower sleeves. The silicone cover body is connected to the protective ring through friction, which has poor stability and is easy to loosen and fall off during use. In addition, the layer at the gap has obvious warping, which affects the appearance of the product.

[0005] 2. It does not have a humidification function, which is not suitable for users with eye diseases or dry eyes. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The utility model is further described below in conjunction with embodiments.

[0033] Example:

[0034] On the one hand, the utility model provides a protective cover body, wherein the cover body 10 has good flexibility, wherein the cover body 10 is integrally formed of a soft PVC material, and the hardness of the cover body 10 of the product is slightly higher than that of the cover body made of silicone material in the prior art. The cover body 10 is mainly used to be mounted on protective glasses, further reducing the gap between the protective ring 31 and the user's face, and reducing the invasion of fine particles (for example: pollen, dust, and droplets) into the eyes.

[0035] The mask body 10 includes a nose bridge portion 11 and an arc-shaped mask member 12 symmetrically arranged along the nose bridge portion 11. One side of the arc-shaped mask member 12 is a face side portion 121, which fits the face of the wearer. The other side of the arc-shaped mask member 12 is a connecting portion, and a continuous plug-in groove 122 is formed at the connecting portion through a double-layer structure, and the protective glasses are inserted into the plug-in groove 122.

[0036] Among them, at the double-layer structure at the relatively outer end of the arc-shaped cover 12, a humidifying part 20 is provided on the inner layer 123 of the double-layer structure, and a slot is provided on the outer layer of the double-layer structure. The outer layer close to the connecting part is divided by the slot 124 to form an elastic drawstring 14.

[0037] In addition, the utility model provides a protective eyeglasses on the other hand, including the above-mentioned cover body 10, and also including a frame 30, a lens 40 is fixed inside the frame 30, and a protective ring 31 is formed by extending inwardly of the frame 30, and the cover body 10 is inserted into the protective ring 31.

[0038] Specifically, in the implementation of the stable connection between the lifting cover body 10 and the protective ring 31, the slot is a strip-shaped strip hole 13, and the width of the strip hole is 3 to 4 mm; this product is provided with strip holes 13 at the outer ends of both sides of the outer layer 124 of the arc-shaped cover part 12, and the strip holes 13 are integrally formed by an injection molding process, and the outer layer 124 on the side close to the connection part is divided by the strip hole 13 to form an elastic drawstring 14. In this embodiment, the width of the strip hole 13 is 3 to 4 mm, and the end of the strip hole 13 is a semicircular groove transition, which ensures that the elastic drawstring 14 will not be torn at the strip hole 13 when it is elastically fitted on the outside of the protective ring 31. When using and installing, the temples 50 of the glasses are first passed through the strip hole 13, and then the cover body 10 is put on the protective ring 31 as a whole.

[0039] This product forms an elastic drawstring 14 by splitting the outer layer 124 at the relatively outer end of the arc-shaped cover part 12. When installed in conjunction with the protective goggles, the elastic drawstring 14 is elastically attached to the outer side of the protective ring 31, so that a complete elastic fitting surface is formed between the cover body 10 and the protective ring 31, and the installation is secure and not easy to loosen or fall off. In addition, the outer layer 124 of the cover body 10 is a continuous whole, which avoids the occurrence of warping edges.

[0040] For some users with eye diseases or dry eyes, in the implementation of the humidification function of this product:

[0041] A humidifying part 20 is provided on the inner side of the outer end of the arc-shaped cover member 12 , wherein the humidifying part 20 includes a fixing part 21 integrally formed with the arc-shaped cover member 12 , and also includes a water absorbing part 22 , and the water absorbing part 22 is detachably plugged into the fixing part 21 .

[0042] Specifically, the fixing portion 21 is a pair of ribs 211 arranged at intervals. The ribs 211 are integrally formed with the cover body 10 through injection molding. The ribs 211 can be arranged in parallel or intersecting. The ribs 211 protrude 3mm from the surface of the inner layer 123, and the absorbent member 22 is clamped and fixed between the ribs 211 by interference fit. In this embodiment, the absorbent member 22 is preferably a block-shaped absorbent cotton, and the cross-section of the main shape of the absorbent cotton can be rectangular, semicircular, trapezoidal, etc., as long as it can meet the clamping requirements of interference fit.

[0043] Preferably, the thickness of the inner layer 123 of the arc-shaped cover 12 is designed to be greater than the thickness of the outer layer 124. This design makes the elastic drawstring 14 on the thinner outer layer 124 easier to be pulled and deformed, while the thicker inner layer 123 adapts to the thickness of the ribs 211, avoids injection molding defects, and maintains good elastic clamping force of the ribs 211. By clamping and fixing the two ribs 211, the liquid medicine and water absorbed on the absorbent cotton can be efficiently volatilized without obstruction, and the user who wears it can complete the role of auxiliary treatment and eye care.

[0044] In addition, in this embodiment, the inner side surfaces of the ribs 211 can be designed as inclined surfaces 212, and the inclined surfaces 212 are inclined from inside to outside and contract inward. The design of the inclined surfaces 212 can improve the clamping and fixing stability of the water absorbent 22 in the ribs 211.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
