Description

Technical Field

[0001] This utility model belongs to the field of eyewear technology and relates to a sports eyeglasses. Background Technology

[0002] Sports glasses are safety glasses specifically designed for sports, suitable for outdoor activities such as skiing, cycling, and mountaineering. Like traditional glasses, sports glasses mainly consist of lenses, frames, temples, and nose pads. Currently, glasses for sports like cycling generally use traditional temples, while glasses for sports like skiing typically use headbands instead of temples to accommodate high-difficulty movements such as jumping and flipping. Existing sports glasses on the market offer limited functionality, meaning users with multiple sports needs often need to purchase at least two pairs, inevitably increasing costs and potentially reducing their desire to participate in any particular sport. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a new type of sports glasses. The technical problem this invention aims to solve is the high cost of using existing sports glasses.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A type of sports eyeglass includes a main frame, characterized in that the main frame has a snap-fit ​​groove and an unlocking block partially embedded in the snap-fit ​​groove. The snap-fit ​​groove has a notch on its end wall and an elastic sheet protruding towards the groove opening and capable of elastic deformation on its bottom wall. The unlocking block is hinged to the main frame at its center. One end of the unlocking block has a pressing protrusion that abuts against the elastic sheet, and the other end of the unlocking block has a locking protrusion. Block-shaped mounting seats are symmetrically arranged on both sides of the main frame. Each mounting seat has a snap-fit ​​ring extending from the notch into the snap-fit ​​groove, and the locking protrusion is engaged with the snap-fit ​​ring of the mounting seat by the action of the elastic sheet to form a lock.

[0006] The main frame of these sports glasses has symmetrical and detachable block-shaped mounting bases on both sides. When in use, the mounting bases are hinged with temples or fixing blocks for securing the elastic straps. This allows users to switch between the temples and elastic straps of the sports glasses by detaching and assembling the mounting bases. As a result, the main frame can be used in various outdoor scenarios such as skiing, cycling, and mountaineering, without the need to purchase multiple pairs of sports glasses, thus solving the problem of high operating costs of existing sports glasses.

[0007] Specifically, when the user presses the end of the unlocking block with the pressing protrusion, the pressing protrusion is forced to squeeze the elastic piece and move inward around its hinge with the main frame. Correspondingly, the end of the unlocking block with the locking protrusion moves outward around its hinge with the main frame, causing the locking protrusion to disengage from the locking ring. At this point, the user only needs to remove the mounting base with the temple hinged to it. Then, the user can insert the locking ring of the mounting base with the fixing block hinged to it into the locking groove through the notch. Under the action of the elastic piece, the locking protrusion of the unlocking block can rotate inward around the hinge and lock into the locking ring to form a lock. The above steps are repeated once on the other side of the mounting base.

[0008] In the aforementioned type of sports glasses, a ring-shaped auxiliary mounting frame is snapped onto the inner side of the main frame, and the inner side of the auxiliary mounting frame is covered with an anti-collision buffer pad. The ring-shaped anti-collision buffer pad can be made of impact-resistant materials such as polycarbonate. Firstly, it effectively cushions the impact of the lenses on the eyes during falls, reducing the risk of corneal scratches or eye contusions. Secondly, it fits closely to the face, forming a sealed space to prevent cold air and snow particles from entering the eyes. Thirdly, it balances internal and external air pressure, preventing the lenses from fogging or frosting, and improving visual clarity.

[0009] In the aforementioned type of sports glasses, a secondary frame is also provided on the inner side of the main frame. The bridge of the main frame has several limiting grooves, and the bridge of the secondary frame has several limiting protrusions, which are engaged with the limiting grooves. The secondary frame can accommodate prescription lenses, thus meeting the needs of nearsighted individuals and further enriching the functionality of the sports glasses.

[0010] In the aforementioned type of sports glasses, two mounting bases are each equipped with temples. Each temple includes a temple body and a connecting block. The temple body has a connecting groove. One end of the connecting block is hinged to the mounting base and can rotate inward and outward relative to the mounting base. The other end of the connecting block extends into the connecting groove and is hinged to the groove wall. The temple body can rotate up and down relative to the connecting block. The groove wall has several slots arranged side by side. The connecting block has several protrusions arranged side by side. The distance between two adjacent protrusions is the same as the distance between two adjacent slots. The number of protrusions is less than the number of slots, and each protrusion can be fitted into a slot. This design allows for both up-and-down and inward / outward rotation adjustment of the temples. The inward / outward rotation adjustment facilitates the unfolding and wearing of the temples and their folding and storage. The up-and-down rotation adjustment can accommodate users with different ear heights or users with different ear heights, providing good versatility and further enriching the functionality of these sports glasses.

[0011] In the aforementioned type of sports glasses, two mounting bases are each hinged with a fixing block that can rotate inwards and outwards relative to the mounting base. Each fixing block has a retaining ring with a break. These fixing blocks facilitate the securing of the elastic lens strap.

[0012] Compared with existing technologies, the advantages of this sports glasses are as follows: The main frame of this sports glasses has symmetrical and detachable block-shaped mounting bases on both sides. The mounting bases can be hinged to the temples or fixed blocks for fixing the elastic straps. This allows users to switch between the temples and elastic straps of the sports glasses by assembling and disassembling the mounting bases. As a result, the main frame can be used in various outdoor scenarios such as skiing, cycling, and mountaineering, without the need to purchase multiple pairs of sports glasses, thus solving the problem of high operating costs of existing sports glasses.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] Example 1

[0023] A type of sports eyeglass includes a main frame 1. The main frame 1 has a snap-fit ​​groove 1a and an unlocking block 4 partially embedded in the snap-fit ​​groove 1a. The end wall of the snap-fit ​​groove 1a has a notch 1b, and the bottom wall of the snap-fit ​​groove 1a has an elastic sheet 1c that protrudes towards the groove opening and can undergo elastic deformation. The middle part of the unlocking block 4 is hinged to the main frame 1. One end of the unlocking block 4 has a pressing protrusion 4a that abuts against the elastic sheet 1c, and the other end of the unlocking block 4 has a locking protrusion 4b. Block-shaped mounting seats 2 are symmetrically arranged on both sides of the main frame 1. The mounting seats 2 have snap-fit ​​rings 2a that extend from the notch 1b into the snap-fit ​​groove 1a, and the locking protrusions 4b are engaged in the snap-fit ​​rings 2a of the mounting seats 2 under the action of the elastic sheet 1c to form a lock.

[0024] Specifically, each of the two mounting bases 2 is provided with a temple 7. Each temple 7 includes a temple body 7a and a connecting block 7b. The temple body 7a has a connecting groove 7a1. One end of the connecting block 7b is hinged to the mounting base 2 and can rotate relative to the mounting base 2 (the connecting block 7b is hinged to the mounting base via a vertically arranged hinge shaft). The other end of the connecting block 7b extends into the connecting groove 7a1 and is hinged to the groove wall of the connecting groove 7a1. The temple body 7a can rotate relative to the mounting base 2. The connecting block 7b rotates up and down (the temple body 7a is hinged to the connecting block 7b via a horizontally arranged hinge shaft). The groove wall of the connecting groove 7a1 has several slots 7a2 arranged side by side. The connecting block 7b has several protrusions 7b1 arranged side by side. The distance between two adjacent protrusions 7b1 is the same as the distance between two adjacent slots 7b2. The number of protrusions 7b1 is less than the number of slots 7a2, and each protrusion 7b1 can be embedded in the slot 7a2.

[0025] Alternatively, each of the two mounting bases 2 may be hinged with a fixing block 8 that can rotate inward and outward relative to the mounting base 2, and the fixing block 8 may have a fixing ring 8a with a break.

[0026] The main frame 1 of these sports glasses has symmetrically and detachably connected block-shaped mounting bases 2 on both sides. In use, the mounting bases 2 are hinged with temples 7 or fixing blocks 8 for securing the elastic lens strap 9 (the elastic lens strap 9 preferably has a D-ring for adjusting its length). When the user presses the end of the unlocking block 4 with the pressing protrusion 4a, it forces the pressing protrusion 4a to squeeze the elastic piece 1c and move inward around its hinge with the main frame 1. Correspondingly, the end of the unlocking block 4 with the locking protrusion 4b moves outward around its hinge with the main frame 1, causing the locking protrusion 4b to disengage from the locking ring 3. At this point, the user only needs to remove the glasses. The mounting base 2 with hinged temples is sufficient. Then, the user inserts the locking ring 3 of the mounting base 2 with the fixing block 8 into the locking groove 1a through the notch 1b. Under the action of the elastic plate 1c, the locking protrusion 4b of the unlocking block 4 can rotate inward around the hinge and lock into the locking ring 2a to form a lock. Repeat the above steps on the other side of the mounting base 2. This allows the user to switch between the temples and the elastic strap of the sports glasses by disassembling and assembling the mounting base 2. This enables the main frame 1 to be used in various outdoor scenarios such as skiing, cycling, and mountaineering, without the need to purchase multiple pairs of sports glasses, thus solving the problem of the single function of existing sports glasses.

[0027] When the temple 7 needs to be adjusted up and down, the temple body 7a can be moved up or down simply by moving it. Since the number of protrusions 7b1 is less than the number of slots 7a2, the temple body 7a can move upward relative to the connecting block 7b under the action of external force until the uppermost protrusion 7b1 is embedded in the uppermost slot 7a2. Similarly, the temple body 7a can move downward relative to the connecting block 7b under the action of external force until the lowermost protrusion 7b1 is embedded in the lowermost slot 7a2. The distance that the temple body 7a moves up and down is the same as the distance between two adjacent protrusions 7b1 (or two adjacent slots 7a2).

[0028] Example 2

[0029] The structure and principle of this embodiment are basically the same as those of Embodiment 1. The difference is that: further, an annular auxiliary mounting frame 5 is snapped into the inner side of the main frame 1, and the inner side of the auxiliary mounting frame 5 is covered with an anti-collision buffer pad.

[0030] Example 3

[0031] This embodiment is basically the same in structure and principle as Embodiment 1 or Embodiment 2. The difference is that: further, a secondary frame 6 is provided on the inner side of the main frame 1. The bridge of the nose of the main frame 1 has several limiting grooves 3, and the bridge of the nose of the secondary frame 6 has several limiting protrusions 6a. The limiting protrusions 6a are inserted into the limiting grooves 3 one by one.
