Description

TECHNICAL FIELD

[0001] The utility model belongs to optical device technical field relates to a pair of glasses. BACKGROUND

[0002] Glasses are common optical devices in the prior art, which are mainly composed of two parts of lens and frame, further, the frame includes a frame for assembling the lens and a leg hinged to both ends of the frame, and the user holds the nose pad on the frame through the nose bridge when wearing, and the two legs are hung on the ears.

[0003] For the use of glasses, normal wearing in daily life is no problem, but during the process of users performing intense exercise (such as basketball, football, etc.), accidental injury may occur due to unconscious body contact, and the frame may press the skin around the eyes of the user's face, so the prior art often sets up a soft structure to achieve the effect of buffering, such as the glasses with sweat blocking structure disclosed in Chinese patent (authorized announcement number: CN217879872U), which includes a sweat blocking structure and a frame, the sweat blocking structure includes a sweat blocking bracket and a sweat blocking foam, the sweat blocking bracket is connected to the frame, the sweat blocking bracket is provided with a hollow part corresponding to the lens mounting port, and the sweat blocking foam is arranged on the side of the sweat blocking bracket away from the frame; the upper end surface of the sweat blocking foam on the upper side of the sweat blocking bracket is a flat surface; the sweat blocking foam on the lower side of the sweat blocking bracket is provided with a sweat groove.

[0004] According to the description of the specification and the description of the specification Figure 1 It can be seen that the structure disclosed in the comparative document realizes the buffering protection of the head and the eyes by using the sweat blocking foam as the buffering structure, and avoids the accumulation of sweat by setting the sweat groove structure.

[0005] But from the description of the comparative document in paragraph 025 and the description in paragraph 0031, it can be seen that the sweat blocking bracket is preliminarily positioned by pressing the middle part of the sweat blocking bracket into the mounting seat slot in the middle part of the frame, and then the two sides of the sweat blocking bracket are clamped into the insertion port of the leg for complete fixation, but for different users, the head width, contour and other factors are various, resulting in that the sweat blocking bracket and most of the users' eye sockets do not match, and the adaptability is poor. SUMMARY

[0006] The utility model aims at the above-mentioned problems existing in the prior art, and provides a pair of glasses, and the technical problem to be solved by the utility model is how to improve the adaptability of the glasses.

[0007] The utility model discloses a purpose can be realized through the following technical schemes: a pair of glasses, including the frame and the hinge in the both ends of frame glasses, the glasses still include the support, the support is located between two mirror leg and with the middle part of frame clamping, and the back of support has the buffer pad made of flexible material along the circumference, it is characterized in that, the support and two mirror leg sliding connection and both ends and the inside of two mirror leg abut tightly, two mirror leg can swing inwards make the support be extruded and keep positioning inwards, and two mirror leg can swing outwards make the support expand and keep positioning outwards.

[0008] The present application uses the support as the carrier of the buffer pad, and realizes the preliminary positioning by clamping with the middle part of the frame. It is worth mentioning that, under the premise that the stability of the support is ensured, the flexible buffer pad arranged on the back of the support is in contact with the skin around the eye socket of the user. When the glasses are touched and pressed against the face of the user during body contact, most of the impact force can be unloaded through the material properties of the buffer pad, so as to avoid the user's eye injury caused by high-intensity impact. On this basis, the present application differs from the prior art in that the two ends of the support are connected to the two legs by sliding connection instead of clamping connection in the prior art. For users with different head sizes, after the support is preliminarily positioned on the frame and connected to the two legs by sliding connection, it is necessary to note that the inner side walls of the support and the two legs are in abutting state after the above installation is completed. That is, the support itself has a tendency to expand outward, but its deformation is inhibited due to the cooperation of the frame and the two legs. At this time, when the user swings the two legs inward, the two legs can further increase the extrusion force on the two ends of the support due to the increase in the swing amount, so that the support is further extruded and deformed inward and kept in position. Thus, the curvature of the support and the buffer pad arranged thereon is larger. Conversely, when the user swings the two legs outward, the two legs can reduce the extrusion force on the two ends of the support due to the increase in the swing amount, so that the support can expand and deform outward by the elastic force it possesses and keep in position. Thus, the curvature of the support and the buffer pad arranged thereon is smaller. In this way, the buffer pad on the back of the support can be more fully in contact with the face by increasing the contact area to reduce the local pressure, thereby improving the buffering and protection effect. The present application can adapt to different needs of different users and has higher adaptability.

[0009] In the above glasses, the two ends of the support are inwardly curved, and the two ends of the front surface of the support have protrusions. A plurality of clamping grooves are formed on the inner side surface of each temple, and the plurality of clamping grooves are arranged at intervals along the length direction of the temple. The protrusions can be clamped in any one of the clamping grooves. Specifically, the support is curved at its two ends, thereby ensuring that it has sufficient elastic deformation capability. After the deformation degree of the support is adjusted, the two ends of the support are clamped by the protrusions and the corresponding clamping grooves on the two temples, thereby realizing positioning of the support in the curved state. Alternatively, limiting grooves can be arranged at the two ends of the support, and the temples are connected to the end of the support by interference clamping, and the positioning is realized by the friction force of the interference fit.

[0010] In the above glasses, the plurality of clamping grooves are arranged close to the hinged end of the temple. The torsion of the hinged end of the temple provides pre-tightening for the cooperation between the temple and the support, thereby ensuring the stability of the connection between the support and the temple in the compressed and stretched state.

[0011] In the above glasses, a sliding groove is formed on the inner side surface of the temple on both sides of the plurality of clamping grooves. Each sliding groove extends to the edge of the hinged end of the temple. One of the sliding grooves penetrates the top surface of the temple, and the other sliding groove penetrates the bottom surface of the temple. The two ends of the support have sliding blocks on the upper and lower sides of the protrusions, and each sliding block is slidingly connected in each sliding groove. The sliding cooperation of each sliding block and each sliding groove ensures the guidance of the temple when it is turned inward or outward, thereby avoiding the misalignment of the temple and the protrusion.

[0012] In the above glasses, a protruding portion is formed between the two sliding grooves on the inner side of each temple, and the plurality of clamping grooves are formed on the protruding portion. Limiting grooves are formed between the two sliding blocks at the two ends of the support, and the protruding portion is slidingly connected in the limiting grooves. This arrangement further improves the connection stability between the two temples and the support and ensures the guidance effect.

[0013] In the above glasses, the protrusions are semispherical, and the clamping grooves are semispherical grooves. The cooperation of the spherical outer wall of the protrusion and the spherical inner wall of the clamping groove ensures stable clamping and realizes quick unlocking.

[0014] Compared with the prior art, the glasses have the following advantages:

[0015] The swinging of the temples realizes the extrusion of the support or the outward expansion of the support by the elastic deformation of the support, thereby ensuring that the curvature of the support and the buffer pad on the back of the support for contacting the skin of the user is adjustable, ensuring the fit of the buffer pad and the skin of the face of the user, and having higher adaptability.

[0021] The following is a specific embodiment of the present utility model and further describes the technical scheme of the present utility model in combination with the drawings, but the present utility model is not limited to these embodiments.

[0022] As Figure 1 shown, the present glasses include a frame 1 and a temple 2 hinged at both ends of the frame 1, in combination Figure 3 , the present glasses also include a bracket 3, the shape profile of the bracket 3 is similar to that of the frame 1, and the middle part is clamped with the middle part of the frame 1. For how to clamp the two, reference can be made to the scheme disclosed in the comparative document CN217879872U. The connection relationship in this application will not be described in more detail. The two ends of the bracket 3 are bent inwardly away from the frame 1. On the back surface, a buffer pad 34 made of flexible material is adhered or integrally formed in the circumferential direction. The material for making the buffer pad 34 can also be referred to the comparative document CN217879872U. On the front surface of the bracket 3, two sliding blocks 32 protruding outwardly are provided in the transverse direction at the edges of the two ends. The two sliding blocks 32 at the two ends of the bracket 3 are provided in the vertical direction. The limiting slot 33 is formed between the two sliding blocks 32 at the same end. The protruding head 31 in the form of a hemisphere is provided on the groove bottom wall of the limiting slot 33.

[0023] In combination Figure 4 , two slides 22 are provided on the inner side surface of each temple 2. Both slides 22 are provided in the length direction of the temple 2 and extend to the hinged end of the temple 2. One slide extends through the top surface of the temple 2, and the other slide extends through the bottom surface of the temple 2. Between the two slides 22 on each temple 2, the protruding part 23 protruding relative to each slide 22 is formed. A plurality of card slots 21 are provided on the protruding part 23. Each card slot 21 is a hemispherical slot, and the plurality of card slots 21 are provided in the length direction of the temple 2.

[0024] When assembling, the middle part of the bracket 3 and the middle part of the frame 1 are clamped, and at the same time, the two sliding blocks 32 at one end of the bracket 3 are slidingly connected in the two sliding channels 22 of one of the two temple arms 2, the two sliding blocks 32 at the other end of the bracket 3 are slidingly connected in the two sliding channels 22 of the other temple arm 2, and the protruding part 23 on one of the two temple arms 2 is embedded in one of the limiting grooves 33 on the bracket 3, and the protruding part 23 on the other temple arm 2 is embedded in the other limiting groove 33 on the bracket 3.

[0025] After assembly is completed, the two temple arms 2 are in an outward swinging open state, and in this state, the user can adjust by outwardly bending or inwardly pressing the two temple arms 2. Specifically, when the two temple arms 2 are outwardly bent, since the limiting of the temple arm 2 on the bracket 3 is invalid, the bracket 3, which is originally in a compressed state, is stretched outward by the elastic deformation force it has, and under the premise that the bending curvature of the bracket 3 and the back buffer pad 34 is smaller, the protruding heads 31 at both ends are embedded in any one of the clamping grooves 21 farther away from the hinge end of the temple arm 2, so as to realize the positioning of the bracket 3 and the buffer pad 34. Conversely, when the two temple arms 2 are inwardly pressed, the bracket 3 is inwardly contracted by the compression force, so that the bending curvature of the bracket 3 and the back buffer pad 34 is larger, and at the same time, the protruding heads 31 at both ends are embedded in any one of the clamping grooves 21 closer to the hinge end of the temple arm 2, so as to realize the positioning of the bracket 3 and the buffer pad 34.

[0026] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0027] Although the terms such as frame 1, temple arm 2, clamping groove 21, sliding channel 22, protruding part 23, bracket 3, protruding head 31, sliding block 32, limiting groove 33, and buffer pad 34 are used more frequently herein, but the possibility of using other terms is not excluded. The use of these terms is only to facilitate the description and explanation of the essence of the present application; any additional limitation is contrary to the spirit of the present application.
