Description

Technical Field

[0001] This application relates to the field of zoom glasses technology, specifically to an anti-slip device for the zoom adjustment knob of zoom glasses. Background Technology

[0002] The zoom lens knob is a component used to adjust the focal length of the glasses. By operating the knob, the wearer can obtain a clear field of vision at different viewing distances. The zoom lens knob is usually located on the temple, generally near the frame, for easy operation by the wearer.

[0003] Existing zoom glasses knobs are mainly made of one piece of plastic. However, the outer surface of zoom glasses knobs made of plastic is relatively smooth, which makes it easy for users to slip when turning the zoom glasses knob, resulting in the zoom glasses knob not being adjusted accurately enough.

[0004] Therefore, there is an urgent need for an anti-slip device for the zoom adjustment knob of zoom glasses to solve the problem of insufficient precision in the adjustment of zoom glasses knob. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an anti-slip device for the zoom adjustment knob of zoom glasses, which has the advantage of improving the adjustment accuracy of zoom glasses and solves the problem of insufficient precision in the adjustment of zoom glasses knobs.

[0006] To achieve the above objectives, this application provides the following technical solution: a zoom adjustment knob anti-slip device for zoom glasses, comprising a knob body, an anti-slip mechanism provided on the outer side of the knob body, and an adjustment mechanism provided inside the knob body;

The reinforcing ribs are located inside the knob body, and the metal support mesh, sponge plate, and carbon fiber mesh are arranged sequentially from the inside to the outside in the grooves on the outside of the knob body.

[0008] The knob body is supported by reinforcing ribs, which increases its strength. At the same time, the round holes can increase the friction of the reinforcing ribs. The carbon fiber mesh is supported by the sponge plate, which makes the carbon fiber mesh more flexible. The carbon fiber mesh is located on the outside of the knob body, which can increase the friction of the knob body, so that the knob body will not slip and the knob body will hover more accurately. At the same time, it can make the zoom glasses zoom more accurately.

[0009] Preferably, a through hole is provided on the outer wall of the knob body, and several groups of the through holes are evenly distributed on the outer side of the knob body.

[0010] Preferably, the outer side of the reinforcing rib has several sets of circular holes, and the several sets of circular holes are linearly distributed on the outer side of the reinforcing rib.

[0011] The round hole is used to reduce the weight of the knob body.

[0012] Preferably, the adjustment mechanism includes a support plate, an adjustment screw, a wedge block, a connecting rod, and a connecting piece. The support plate is disposed inside the knob body, the adjustment screw is threaded to the inner side of the support plate, the connecting rod is inserted into the bottom of the knob body, the wedge block is disposed between the adjustment screw and the connecting rod, the connecting piece is sleeved on the outer side of the connecting rod, and the connecting piece is fixedly connected to the bottom of the knob body by bolts.

[0013] The wedge block is used to hold the rotary joint rod in place; turning the adjusting screw drives the wedge block to move linearly, thereby tightening or loosening the rotary joint rod to change the axial position of the knob body on the rotary joint rod.

[0014] Preferably, the outer side of the connecting piece is provided with a bolt body, and the outer side of the screw rod is provided with several sets of insertion holes.

[0015] The screw rod is fixed by fitting the bolt body with different insertion holes.

[0017] In summary, this application includes at least one of the following beneficial effects:

[0018] 1. The zoom adjustment knob of this zoom glasses has an anti-slip device. When the knob body is in use, the reinforcing ribs support the knob body, increasing its strength. At the same time, the round hole can increase the friction of the reinforcing ribs. The carbon fiber mesh, supported by the sponge plate, makes the carbon fiber mesh more flexible. The carbon fiber mesh is located on the outside of the knob body, which can increase the friction of the knob body, preventing the knob body from sliding and making the knob body hover more accurately. At the same time, it makes the zoom glasses zoom more accurately.

[0019] 2. The zoom adjustment knob of this zoom glasses has an anti-slip device. When the knob is in use, the user can rotate it to adjust the screw. The adjusting screw presses against the wedge block, thereby adjusting the position of the wedge block. This allows the rotating rod to be inserted to different depths, making it easier to adjust the installation position of the knob and making the knob easier to rotate. Attached Figure Description

[0028] The anti-slip mechanism includes reinforcing ribs 111, metal support mesh 112, sponge board 113, and carbon fiber mesh 114. The reinforcing ribs 111 are located inside the knob body 1. The metal support mesh 112, sponge board 113, and carbon fiber mesh 114 are arranged sequentially from the inside to the outside in the grooves on the outside of the knob body 1. Through holes 115 are opened on the outer wall of the knob body 1. Several sets of through holes 115 are evenly distributed on the outside of the knob body 1. Several sets of round holes 116 are opened on the outside of the reinforcing ribs 111. Several sets of round holes 116 are linearly distributed on the outside of the reinforcing ribs 111.

[0029] Through the above technical solution, when the knob body 1 is in use, the reinforcing rib 111 supports the knob body 1, thereby increasing the strength of the knob body 1. At the same time, the round hole 116 can increase the friction of the reinforcing rib 111. The carbon fiber mesh 114 is supported by the sponge plate 113, making the carbon fiber mesh 114 more flexible. The carbon fiber mesh 114 is located on the outside of the knob body 1, which can increase the friction of the knob body 1, so that the knob body 1 will not slide, making the knob body 1 hover more accurately, and making the zoom glasses zoom more accurately.

[0030] The through hole 115 connects the knob body 1 with the metal support mesh 112, the sponge plate 113 and the carbon fiber mesh 114.
