Description

Technical Field

[0001] This utility model relates to the field of eyewear technology, and more specifically, to a sports eyeglass and its lens assembly locking structure. Background Technology

[0002] To adapt to different lighting conditions, sports glasses typically feature replaceable lens assemblies. These assemblies are usually attached to the frame magnetically or via clips. Magnetic attachment facilitates lens replacement, but the lenses can easily fall off during vigorous rolling or rolling movements. Clip-on attachments, using a mechanism where protrusions and slots mate to secure the lens assembly, offer better protection against it falling off. However, most existing protrusion-slot mating mechanisms are not as robust as... Figure 1 As shown, it is inconvenient to replace the lens assembly.

[0003] Therefore, it is necessary to develop a locking structure that can effectively fix the lens assembly and facilitate replacement. Utility Model Content

[0004] The purpose of this invention is to provide a sports eyeglass that solves the technical problem that existing lens assembly locking structures fail to facilitate replacement when effectively fixing the lens assembly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A lens assembly locking structure includes an insertion block for inserting into a wearing frame, a locking buckle for movably locking the lens assembly onto the wearing frame, a lever for driving the locking buckle to lock the lens assembly, and a J-shaped hook disposed in the middle of the lever and movably locking the lever onto the insertion block; the insertion block has a first through hole for the J-shaped hook to pass through, and a first latching block adapted to the J-shaped hook is formed on the side wall of the first through hole; one end of the lever is hinged to the insertion block, the other end is for the user to lever, and the middle part is hinged to the locking buckle; the J-shaped hook is movably latched onto the first latching block.

[0007] Preferably, the locking buckle is provided with a second locking block for locking the lens assembly.

[0008] Preferably, the line connecting the hinged end of the lever block and the plug block to its middle part and the first snap-fit ​​block forms a triangle.

[0009] Preferably, the plug block has a second through hole for installing an elastic band.

[0010] Another objective of this invention is to provide sports glasses, which include a frame, a lens assembly, and the aforementioned lens assembly locking structure; both ends of the frame are movably connected to a connecting block, and the locking buckle movably locks the lens assembly onto the frame.

[0011] Preferably, the lens assembly includes a lens frame, a lens disposed on the outside of the lens frame, and two connecting buckles respectively disposed at one end and the other end of the lens frame; the locking buckle is a movable locking connecting buckle.

[0012] This invention has the following advantages: First, a T-shaped hook is formed by the lever and the J-shaped hook. Then, the hinged relationship between this hook and the insertion block and the locking buckle allows the J-shaped hook to pull the locking buckle to press the lens assembly. When the J-shaped hook hooks the first locking block, the locking buckle locks the lens assembly onto the wearing frame. When the lever is pulled away from the insertion block, the locking buckle no longer locks the lens assembly, at which point the lens assembly can be easily removed from the wearing frame for replacement.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] This utility model provides a lens assembly locking structure, such as Figure 2-9 As shown, the device includes an insertion block 1 for inserting into a wearing frame 5, a locking buckle 2 for movably locking a lens assembly 6 onto the wearing frame 5, a lever 3 for driving the locking buckle 2 to lock the lens assembly 6, and a J-shaped hook 4 located in the middle of the lever 3 and movably locking the lever 3 onto the insertion block 1. The insertion block 1 has a first through hole 11 through which the J-shaped hook 4 passes, and the insertion block 1 forms a first locking block 12 adapted to the J-shaped hook 4 on the side wall of the first through hole 11. One end of the lever 3 is hinged to the insertion block 1, and the other end is for the user to move. The middle part is hinged to the locking buckle 2. The J-shaped hook 4 is movably locked with the first locking block 12.

[0027] Specifically, the upper surface of the left end of the insertion block 1 is provided with a hinge structure, which is hinged to the left end of the lever block 3 by means of a pin; the first through hole 11 is located in the middle of the insertion block 1, and the first locking block 12 is located on the left side wall of the first through hole 11. The lever block 3 is π-shaped, and a J-shaped hook 4 is integrally formed in the middle part; the middle part of the lever block 3 is hinged to the lower right end of the locking buckle 2 by means of a pin, and the upper left end of the locking buckle 2 locks the lens assembly 6 onto the wearing frame 5 by moving and pressing the lens assembly 6.

[0028] The method of using the lens assembly locking structure provided by this utility model is as follows: Insert the two plug blocks 1 into the left and right ends of the wearing frame 5 respectively, and then install the two lens assembly locking structures on the wearing frame 5; then lift the right end of the lever block 3 upwards to release the locking buckle 2; then place the lens assembly 6 at an appropriate position on the outside of the wearing frame 5, and lift the right end of the lever block 3 downwards to make the J-shaped hook 4 engage with the first locking block 12. At this time, the upper left end of the fastener 2 locks the lens assembly 6 onto the wearing frame 5 by pressing the lens assembly 6.

[0029] This invention firstly forms a T-shaped pull hook by connecting the lever 3 and the J-shaped hook 4. Then, by utilizing the hinged relationship between this pull hook and the insertion block 1 and the locking buckle 2, the J-shaped hook 4 can pull the locking buckle 2 to press the lens assembly 6. When the J-shaped hook 4 hooks the first locking block 12, the locking buckle 2 locks the lens assembly 6 onto the wearing frame 1. When the lever 3 is pulled away from the insertion block 1, the locking buckle 2 no longer locks the lens assembly 6, at which point the lens assembly 6 can be easily removed from the wearing frame 5 for replacement.

[0030] Furthermore, the locking buckle 2 is provided with a second locking block 21 for locking the lens assembly 6.

[0031] like Figure 1 and Figure 9 As shown, by opening a locking groove 631 at the end of the lens assembly 6 that is compatible with the second snap-fit ​​block 21, the stability of the lens assembly 6 in the wearing frame 5 can be further improved.

[0032] Furthermore, the line connecting the hinged end of the dial block 3 and the plug block 1 with its middle part and the first snap-fit ​​block 12 forms a triangle.

[0033] like Figure 1-3 As shown, with the end of the lever block 3 that is hinged to the plug block 1 as the first corner point, the hinge point of its middle part and the locking buckle 2 as the second corner point, and the locking point of the first locking block 12 as the third corner point, when the lens assembly 6 is in the locked state, the line connecting the first corner point, the second corner point and the third corner point forms a triangle, wherein the position of the second corner point is variable.

[0034] Furthermore, such as Figure 1As shown, the plug block 1 has a second through hole 13 for installing the elastic band. The elastic band is driven by the plug block 1 to achieve the wearing of the wearing frame 5.

[0035] Another objective of this invention is to provide a pair of sports glasses, which includes a frame 5, a lens assembly 6, and the aforementioned lens assembly locking structure; both ends of the frame 5 are movably connected to a connector block 1, and the locking buckle 2 movably locks the lens assembly 6 onto the frame 5.

[0036] like Figure 7-9 As shown, the wearing frame 5 is made of soft, elastic material, and each of its left and right ends has an insertion slot 51. The insertion slot 51 and the insertion fastener 1 are designed to require a certain insertion and extraction force to insert and remove, thus ensuring that the insertion fastener 1 will not fall off the wearing frame 5 due to vigorous movement by the user. It can only be removed from the wearing frame 5 by the user applying a certain pulling force. In other embodiments, the insertion fastener 1 can also be fixedly installed on the wearing frame 5 in a non-removable manner.

[0037] Furthermore, the lens assembly 6 includes a lens frame 61, a lens 62 disposed on the outside of the lens frame 61, and two connecting buckles 63 respectively disposed on one end and the other end of the lens frame 61; the locking buckle 2 movably locks the connecting buckle 63.

[0038] like Figure 5 As shown, both the lens frame 61 and the connecting buckle 63 are made of rigid plastic through an integral injection molding process, and the lens 62 is embedded in the lens frame 61 through an inlay structure. The connecting buckle 63 has a locking slot 631 for adapting to the second locking block 21.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
