Description

Technical Field

[0001] The utility model relates to the technical field of reading glasses, in particular to a pair of reading glasses with detachable temples. Background Art

[0002] Reading glasses, also known as reading glasses, are a type of optical product, glasses used by people with presbyopia. They are a type of convex lens. Reading glasses are mainly designed to meet the needs of people with presbyopia. The elderly will wear reading glasses when they need to read paper or electronic products, but because reading glasses are convex lenses and the elderly have eye problems, they cannot wear reading glasses for a long time and can only wear them when they need them. When they need reading glasses during daily travel, they need to find reading glasses, which greatly affects their daily travel. Moreover, the lenses of reading glasses are convex lenses instead of plain lenses, which makes it difficult for the elderly to wear them for a long time in daily life. At the same time, when the legs of the reading glasses are damaged, there are too many hinged parts between the legs of the reading glasses and the frame, most of which are small screws and other parts, making it difficult for the elderly to replace the damaged legs on their own, which makes the elderly need to buy reading glasses again. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a pair of reading glasses with detachable temples, which solves the problems in the prior art that the reading glasses are made of convex lenses and cannot be worn for a long time and the temples are difficult to disassemble and replace.

[0004] To achieve the above-mentioned purpose, the utility model provides a pair of reading glasses with detachable temples, comprising a frame and temples, both ends of the frame are provided with fixed blocks, the fixed block is horizontally provided with a swing groove, the swing groove is provided with a hook column, the end of the temple is provided with a hook for rotatably arranged in the swing groove and hooked and cooperated with the hook column, the frame is provided with a flat lens, the flat lens is divided into a presbyopia area and a flat light area, the presbyopia area of ​​the flat lens is prepared by a grinding process, the presbyopia area is arranged below the flat light area, an open groove connected with the swing groove is opened on the outer wall of the fixed block, a closing piece is provided in the open groove for opening the open groove when the temple is relatively parallel to the frame to allow the hook to escape from the swing groove through the open groove, and a limiting piece is provided on the hook for cooperating with the closing piece when the temple is relatively vertical to the frame to prevent the closing piece from opening the open groove.

[0005] The advantages of adopting the above technical solution are: the lenses in the above technology are plain glasses, so that the elderly can focus their eyes on the plain area during daily travel or daily life, which does not affect the elderly's daily use or daily travel, and the presbyopia area of ​​the plain glasses is prepared by a grinding process, that is, the presbyopia area is ground to form a convex lens, thereby realizing the presbyopia function. Therefore, when the elderly need reading glasses, they only need to focus their eyes on the presbyopia area to meet the needs of checking documents or electronic products, etc. At the same time, the presbyopia area is located below the plain area, so that the elderly can look straight ahead through the plain area during daily life or daily travel, which does not affect the elderly's daily life. When looking at paper documents or electronic products, the elderly generally look down, which makes it easier for the elderly to focus their eyes on the presbyopia area; in the above technology, when the temples are damaged, the elderly can close the temples so that the temples and the frame are relatively parallel or approximately parallel. At this time, the operator opens the slot through the closure, and the operator can push the temples so that the hooks are out of the swing through the slots. The movable groove is realized, and then the hook and the hook column are separated, so as to realize the disassembly and replacement of the temples, improve the disassembly and assembly efficiency, and do not need too many small screws and other parts, so as to improve the disassembly and assembly efficiency, facilitate the elderly to replace the temples, and reduce cost expenditure; in the above-mentioned technology, when the temples are not disassembled and replaced and when the glasses are used in daily life, the temples and the frame are relatively vertical or nearly vertical. At this time, the limiting member and the closing member cooperate to close the slot, so that the hook cannot be separated from the swing groove through the slot, thereby realizing the limitation of the hook in the swing groove, so as to avoid the separation of the temples and the frame; in the above-mentioned technology, the plain mirror can be made of UV-proof material, that is, the sunglass lens, so as to meet the daily travel needs of the elderly; in the above-mentioned technology, the presbyopia area and the plain light area of ​​the plain mirror are both formed in one piece by a grinding process or an injection molding process, and the injection molding process and the grinding process are both existing technologies and therefore will not be described in detail; in the above-mentioned technology, the plain mirror and the frame can be formed in one piece according to actual production needs and assembly needs, so as to reduce cost expenditure and improve the overall strength of the frame.

[0006] The utility model is further arranged that: the closing piece includes a closing plate slidably arranged in the slot, the sliding direction of the closing plate is arranged perpendicular to the frame, and when the temples are relatively parallel to the frame, the direction in which the closing plate slides out of the fixed block is arranged relatively perpendicular to the opening direction from the starting end of the temple to the end of the temple.

[0007] The benefit of adopting the above technical solution is that: when the slot needs to be opened, the elderly only need to push the closing plate so that the closing plate slides out of the slot in a direction perpendicular to the frame, thereby exposing the slot and allowing the hook to disengage from the swing slot; in the above technology, when the temples are relatively parallel to the frame, the direction in which the closing plate slides out of the fixed block is relatively perpendicular to the opening direction from the beginning to the end of the temple, so that the closing plate will not slide out of the slot in the direction forward of the frame, so that the closing plate will not easily detach from the frame during daily use, resulting in failure of the closing plate to limit the hook.

[0008] The utility model is further configured as follows: a first rib is provided on the inner wall of the closing plate, and a second rib is provided on the outer peripheral wall of the hook for abutting and cooperating with the first rib when the temple and the frame are relatively vertical, and the second rib is a limiting member.

[0009] The benefits of adopting the above technical solution are: when the temple and the frame are relatively vertical or approximately vertical, the second rib abuts against the first rib, so that the closing plate is difficult to slip in the slot, thereby avoiding the slot being exposed and causing the hook to fall out of the swing slot from the slot; when the temple and the frame are relatively parallel or approximately parallel, the first rib is separated from the second rib, so that the closing plate can slide normally in the slot, thereby realizing the opening and closing of the slot.

[0010] The utility model is further configured as follows: force-bearing convex points are raised on the top wall and the bottom wall of the swing groove, the two force-bearing convex points are arranged opposite to each other, and a third retaining edge is arranged on the outer peripheral wall of the hook for synchronously abutting and cooperating with the two force-bearing convex points when the temple and the frame are relatively vertical.

[0011] The advantages of adopting the above technical solution are: in the above technology, when the temple and the frame are relatively vertical or approximately vertical, the third rib is synchronously abutted and cooperated with the two force-bearing protrusions, so as to prevent the hook from swinging outward excessively, thereby preventing damage to the temple. At the same time, when the temple is subjected to excessive force and opens outward, part of the force it receives will be transmitted to the force-bearing protrusions, so as to prevent the temple from being damaged by high force. In the above technology, the width of the temple is smaller than the distance between the two force-bearing protrusions, so as to ensure that the temple will not contact the two force-bearing protrusions when the temple swings, and the third rib will contact the force-bearing protrusions only when the temple and the frame are relatively vertical or approximately vertical, so as to avoid affecting the swing of the temple.

[0012] The utility model is further provided with: limit grooves are provided on the slotted top wall and the bottom wall along the sliding direction of the closing plate, the closing plate has limit plates extending in the direction of the two limit grooves, and the limit plates are arranged in a snap-fitting manner with the limit grooves.

[0013] The benefit of adopting the above technical solution is that: in the above technology, the limiting plate and the limiting groove are engaged with each other to prevent the closing plate from horizontally escaping from the groove, causing the temples to separate from the frame.

[0014] The utility model is further provided with: a nose pad is integrally connected to the frame.

[0015] The benefit of adopting the above technical solution is that: in the above technology, the frame and the nose pad are formed in one piece, thereby improving the connection strength between the nose pad and the frame.

[0016] The utility model is further configured that: the end of the temple is provided with an anti-detachment hook for hooking the ear of the user, and the anti-detachment hook is made of elastic material.

[0017] The advantages of adopting the above technical solution are as follows: the setting of the anti-drop hook in the above technology improves the stability of the temple on the ear of the elderly. BRIEF DESCRIPTION OF THE DRAWINGS
