Description

Technical Field

[0001] This utility model relates to the field of eyeglasses, and more particularly to a lockable metal pipe holder with adjustable pupil height. Background Technology

[0002] Eyeglasses are lenses set in a frame and worn in front of the eyes to improve vision, protect the eyes, or for decorative purposes. Eyeglasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia, or strabismus. Eyeglasses consist of lenses and frames. Usually, there are nose pads on the inside of the frame and temple tips on the outside of the frame where the temples rest on the ears. The nose pads are an important component for adjusting the angle and position of the lenses and affecting comfort.

[0003] For example, Chinese utility model patent CN222774713U discloses a combination pair of glasses, which, by incorporating detachable lenses and combining with normal vision correction glasses, meets the personalized needs of users in different visual situations and addresses the increasing demands for visual aids as the pace of modern life accelerates, encompassing not only vision correction but also eye protection and fashion styling. However, this structure still has the following significant drawbacks:

[0004] 1. The lens is usually fixed to the pipe and is difficult to adjust. This makes it difficult for the optical center of the lens to match the user's pupil height. This mismatch can cause blurred vision, double vision and other problems during wear, and cause visual fatigue.

[0005] 2. Traditional eyeglass temples are directly hinged to the frame and are generally difficult to remove. Therefore, it is difficult to replace the temples at any time. Even if only the temples are damaged, the entire pair of glasses must be replaced, which is costly. It also limits the replacement of eyeglass temples because they are not aesthetically pleasing.

[0028] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0029] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The following description, in conjunction with the accompanying drawings, details an adjustable pupil height locking metal pipe holder provided in this application through specific embodiments and application scenarios.

[0031] Example 1:

[0032] like Figures 1 to 4 As shown, this application embodiment provides an adjustable pupil height locking metal pipe holder, including a holder 1 and a metal pipe 2; a locking block 3 is fixedly installed at one end of the metal pipe 2, and the locking block 3 is provided with a connecting hole 31; one end of the holder 1 is arc-shaped, and a back plate 41 is fixedly installed at the other end; an adjusting rod 42 that slides with the connecting hole 31 is fixedly provided at the end of the back plate 41 facing away from the holder 1; a pair of symmetrical limiting parts 43 are provided on the adjusting rod 42, and the limiting parts 43 are used to limit the position of the locking block 3.

[0033] Furthermore, the adjusting rod 42 includes a limiting rod 421 and a sliding rod 422 connected at the first end. The limiting rod 421 is mounted on the back plate 41, and the limiting part 43 is disposed on the sliding rod 422. The limiting rod 421 and the sliding rod 422 form an L-shape.

[0034] Furthermore, each of the limiting parts 43 includes a plurality of limiting protrusions 44, which are evenly distributed along the length direction of the sliding rod 422.

[0035] Furthermore, the sliding rod 421 has a transverse groove 45 inside along its length.

[0036] In this embodiment of the application, due to the above-described structure, each limiting part 43 includes three limiting protrusions 44. The three limiting protrusions 44 are evenly distributed along the length of the sliding rod 422. The three limiting protrusions 44 cooperate with the limiting rod 421, so that the leaf 1 has three positions for the user to select. When the user needs to adjust, he can pull the locking block 3. Since the sliding rod 421 has a transverse groove 45 along its length, the sliding rod 421 will be deformed by pressure, so that the connecting hole 31 on the locking block 3 can pass through the limiting protrusion 44. The locking block 3 can slide along the adjusting rod 42. When the connecting hole 31 on the locking block 3 separates from the limiting protrusion 44, the sliding rod 421 returns to its original position. The limiting rod 421 or the corresponding limiting protrusion 44 cooperate to fix the locking block 3 in the current position, thereby completing the adjustment.

[0037] The locking block 3 is made of metal, while the limiting rod 421, sliding rod 422 and limiting protrusion 44 are made of plastic.

[0038] Example 2:

[0039] like Figures 5 to 7As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes a frame 51, a front temple 52 and a rear temple 53. The end of the metal pipe 2 without the locking block 3 is fixedly connected to the frame 51. The front temple 52 is hinged to both sides of the frame 51. The front temple 52 and the rear temple 53 are installed together by a detachable structure 54.

[0040] Furthermore, the detachable structure 54 includes a connecting block 541, a mounting ball 542, and a fixing block 547. One end of the connecting block 541 is fixedly connected to the mounting ball 542 and the fixing block 547, and the other end is fixedly connected to the rear temple 53. The front temple 52 is provided with a fixing groove 548 that slides with the fixing block 547. The mounting ball 542 is provided with a pressing groove 543, which divides the mounting ball 542 into four ball blocks 544. The four ball blocks 544 can approach each other under the action of external force, and the four ball blocks 544 will return to their initial positions after the external force is removed. The front temple 52 is provided with a mounting groove 545 corresponding to the mounting ball 542.

[0041] Furthermore, the mounting groove 545 is a spherical groove adapted to the mounting ball 542, and the radius of the groove opening of the mounting groove 545 is smaller than the radius of the mounting ball 542 when the four ball blocks 544 are in the initial position.

[0042] Furthermore, the detachable structure 54 also includes a rubber plug 546. The connecting block 541 is provided with a connecting groove 55 that communicates with the extrusion groove 543. The rubber plug 546 can be installed in the connecting groove 55 and the extrusion groove 543.

[0043] Furthermore, the connecting groove 55 is provided with a sliding groove 56, and the rubber plug 546 is provided with a sliding block 57 that is adapted to the sliding groove 56, and the sliding block 57 is provided with anti-slip texture 58.

[0044] In this embodiment of the application, due to the above-described structure, when the user needs to replace the rear temple 53, the rubber plug 546 can slide out from the connecting groove 55 and the compression groove 543 by pushing the sliding block 57. At this time, pulling the rear temple 53 will cause the four ball blocks 544 to move closer to each other under the compression of the mounting groove 545, making the volume of the mounting ball 542 smaller. The mounting ball 542 can then detach from the mounting groove 545, thereby allowing the rear temple 53 to be removed. After aligning the mounting ball 542 on the new rear temple 53 with the mounting groove 545, the fixing block 54... Align 7 with the fixing groove 548, press down on the mounting ball 542, the fixing block 547 slides into the fixing groove 548, the mounting ball 542 is squeezed by the groove opening of the mounting groove 545, the four ball blocks 544 will move closer to each other, making the volume of the mounting ball 542 smaller, the mounting ball 542 can slide back into the mounting groove 545, then align the rubber plug 546 with the connecting groove 55, and make the sliding block 57 correspond to the sliding groove 56, push the rubber plug 546, so that it is reinstalled in the connecting groove 55 and the squeezing groove 543, and the installation is completed, thereby achieving the purpose of replacing the rear temple 53;

[0045] There is a certain amount of friction between the rubber stopper 546, the connecting block 541, and the mounting ball 542. When the rubber stopper 546 is installed in the connecting groove 55 and the extrusion groove 543, it is not easy to slip out.

[0046] The sliding block 57 is provided with anti-slip texture 58, which can increase friction and make it easier for the user to remove the rubber stopper 546.
