Embodiment 1

[0039] A nose pad for eyeglass frames such as Figure 1-5 As shown, it includes an oval installation frame 1 and an oval nose pad 2 inserted on its free end surface. The oval nose pad 2 is an arc structure protruding outward. Ear piece 3, the free end face of rotating ear piece 3 is fixedly provided with the T-shaped mounting rod 5 that matches with the mounting block 4 on the spectacle frame, and one end face of the mounting block 4 is provided with a rectangular plug for installing the T-shaped mounting rod 5. Slot 6, the depth of rectangular slot 6 two side walls is symmetrically provided with first rack 7, and the middle part of T-shaped installation rod 5 both sides end faces is all rotatably connected with rotating plate 8, and the rear portion of rotating plate 8 outer end faces is provided with Several second tooth racks 13 engaged with the depth of the inner wall of the rectangular slot 6, and the rear part of the T-shaped mounting rod 5 and the rotating plate 8 are c...

Embodiment 2

[0051] A kind of nose pad that is used for spectacle frame, and its difference with embodiment 1 is that the composition of modified PVC is different, and the preparation method of modified sericite is also not the same, specifically as follows:

[0052] The modified PVC consists of the following raw materials in parts by weight: 125 parts of PVC, 4.0 parts of nano-titanium dioxide, 5.5 parts of modified sericite powder, 3.2 parts of carbon nanotubes, 2.4 parts of antibacterial agents, 2.0 parts of 2-hydroxyl-4- Methoxybenzophenone and 6.5 parts of nano calcium carbonate.

[0053] The preparation method of modified sericite powder is:

[0054] Accurately weigh an appropriate amount of nano-sericite powder, and place it in an antibacterial agent with a temperature of 75°C and 10 times its mass for 25 hours. After soaking, take out the nano-sericite powder and mix it with 15% of its mass. γ-(2,3-Glycidyloxypropoxy)propyltrimethoxysilane, after ultrasonic mixing for 12min, raise...

Embodiment 3

[0056] A kind of nose pad that is used for spectacle frame, its difference with embodiment 1 is that the composition of modified PVC is different, and the preparation method of modified sericite is also not the same; Specifically as follows:

[0057] The modified PVC consists of the following raw materials in parts by weight: 130 parts of PVC, 4.5 parts of nano-titanium dioxide, 5.8 parts of modified sericite powder, 3.5 parts of carbon nanotubes, 2.6 parts of antibacterial agent, 2.5 parts of 2-hydroxyl-4- Methoxybenzophenone and 7.2 parts of nano calcium carbonate.

[0058] The preparation method of modified sericite powder is:

[0059] Accurately weigh an appropriate amount of nano-sericite powder, and place it in an antibacterial agent with a temperature of 80°C and a mass of 12 times its mass for 30 hours. After soaking, take out the nano-sericite powder and mix it with 20% of its mass γ-(2,3-Glycidyloxypropoxy)propyltrimethoxysilane, after ultrasonic mixing for 15 minut...

Abstract

The invention discloses a nose pad for spectacle frames and an installation method thereof, which belongs to the technical field of nose pads. The key points of the technical solution include an oval installation frame and an oval nose pad plugged on its free end surface; an oval installation frame The rear end face of the rotating ear is connected with a rotating lug, and the free end face of the rotating ear is fixed with a T-shaped mounting rod that matches the mounting block on the spectacle frame, and one end of the mounting block is provided with a rectangular shape for installing the T-shaped mounting rod. Slots, the depth of the two side walls of the rectangular slots is symmetrically provided with a first rack, the rotation of the end faces on both sides of the T-shaped installation rod is connected with a rotating plate, and the rear of the rotating plate is provided with several rectangular inserts. A second toothed rack engages deep within the inner walls of the groove. The invention not only has good antibacterial performance and anti-aging performance, but also effectively improves the quality and quality of the nose pad, and can realize quick installation, disassembly and replacement of the nose pad, which is very convenient and quick.

Description

technical field [0001] The invention belongs to the technical field of nose pads, and more specifically relates to a nose pad for spectacle frames and an installation method thereof. Background technique [0002] Glasses are commonly used items in life, and they are often worn at work and in sports. A conventional eyeglass frame includes two opposite lens frame parts for placing lenses, a nose pad part, and arms (or glasses arms) respectively arranged on the edge of the lens frame part. In myopia glasses or sunglasses, it is usually an integrated design, that is, the arm Arms (or glasses legs) are fixed on the edge of the lens frame by screws or other means, and the nose pads are also fixed on the inside of the lens frame by screws. And the frameless glasses usually fix the nose pads, arms (or glasses legs) directly on the lenses. [0003] Today, nose pads for eyeglasses are generally constructed by wings made of soft plastic material (usually PVC, rubber or silicone) at t...
