Description

Technical Field

[0001] The utility model relates to the technical field of scribers, in particular to a spectacle lens template scriber. Background Art

[0002] In recent years, with the advancement of science and technology, the number of patients with myopia or astigmatism has increased. For patients with astigmatism, the axis of eye astigmatism can generally be detected by relevant instruments, which can be used as the prescription for fitting. The astigmatism axis of the glasses needs to be made into a horizontal reference line during lens processing to ensure the accuracy of the horizontal reference line of the processed astigmatism axis, so as to meet the optometry prescription of patients with astigmatism and achieve the purpose of vision correction. Now the scriber usually adopts the shape of a regular hexagonal prism, and the height of its six faces to the marking fixing hole is fixed, that is, the marking height is fixed. For some children's glasses or wide sunglasses, such low or high height marking scenarios, the existing scriber cannot flexibly adjust its marking height. Utility Model Content

[0015] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0016] like Figure 1-6 As shown, a spectacle lens template scriber comprises: a scriber body 100, a scriber pen 200, an adjustment assembly 300 and a pointer assembly 400, wherein the scriber pen 200 is fixed on the scriber body 100, and the adjustment assembly 300 is mounted on the scriber body 100 through the pointer assembly 400;

[0017] The adjustment component 300 includes a turntable 301, a knob 302, a bearing 303 and a fixed cover 304, and the pointer component 400 includes a rotating shaft 401 and a pointer 402. The bearing 303 and the fixed cover 304 are fixed on the scriber body 100. The turntable 301 is embedded in the bearing 303. The knob 302 is fixed on the turntable 301. The turntable 301 has scales. The rotating shaft 401 passes through the turntable 301 and is fixed on the scriber body 100. The pointer 402 is installed on the rotating shaft 401.

[0018] The scriber body 100 is provided with a fixing hole 102, and the fixing hole 102 is an eccentric hole, a height 103 is engraved on the side of the scriber body 100, and a scale 104 is provided at the hand holding portion of the scriber body 100. Since the fixing hole 102 is an eccentric hole, the distances from the center of the circle to each face of the regular hexagonal prism of the scriber body 100 are different, that is, the heights of the hole center from the placement surface are different when flipped to each face, and therefore the height 103 is engraved on each face of the hexagonal prism of the scriber body 100.

[0019] A slot 201 is provided in the marking tool body 100 , and a limiting rubber ring 202 is installed on the slot 201 . The marking pen 200 is fixed on the marking tool body 100 due to the limiting effect of the limiting rubber ring 202 .

[0020] When in use, place the lens and the scriber on a horizontal table, insert the scriber pen 200 into the fixing hole 102, and position the scriber pen 200 through the rubber ring 202 inside it. Move the scriber in the horizontal direction to mark the horizontal line. It should be further explained that when the adjustment part 300 is not adjusted, that is, when the pointer 402 points to the 0 scale, when it is placed on the horizontal plane at different angles, the height of the scriber pen 200 from the placement surface is different, and the height value is the height 103 on each face of the hexagonal prism of the scriber body 100; when the adjustment part 300 starts to adjust, the height of the scriber pen 200 from the placement surface is: the actual height H = the original height 103-the dial scale value s. This structure can flexibly adjust the marking height based on the original height.

[0021] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
