Technical Field
[0001] The utility model belongs to the technical field of glasses and relates to a foldable glasses leg. Background Art
[0002] Glasses are common optical devices in the prior art, and are especially indispensable for people with myopia and hyperopia in today's life. They generally include a lens and a frame, and the frame can be divided into two parts: a frame and temples.
[0003] With the continuous development of technology, people will find that traditional glasses are very inconvenient to carry when going out due to their size. Therefore, in the prior art, a pair of glasses with foldable frames are derived based on traditional glasses. Simply put, in the above-mentioned frame, the frame and the two temples can be folded from the middle along the length direction, so that the space required for the glasses as a whole in the storage state is smaller.
[0004] Although the above structure can be stored more easily, it also causes some problems, especially the two temples. The two rods constituting the temples are usually connected by a hinge, and the hinge between the two rods cannot maintain good firmness. Specifically, when wearing the temples, the user is often required to use both hands to spread the two temples outwards and wear the temples on the ears under the premise of ensuring that the two rods will not flip and fold around the hinge, which is very inconvenient to wear. Summary of the invention
[0005] The purpose of the utility model is to solve the above problems in the existing technology and to propose a foldable glasses leg. The technical problem to be solved by the utility model is: how to ensure the convenience of users wearing glasses.
[0006] The purpose of the utility model can be achieved through the following technical solutions: a foldable eyeglass leg, comprising a front leg and a rear leg hinged to each other, characterized in that one end of the front leg has a receiving groove, one end of the rear leg has a protrusion, a bayonet is connected to the protrusion, the bayonet protrudes from the side wall of the protrusion, a limiting groove is provided on the inner wall of the receiving groove, the protrusion is inserted into the receiving groove and the bayonet is limited in the limiting groove.
[0007] In the foldable glasses leg, the front leg is used to be hinged with the frame, and the rear leg is hinged with the front leg, so as to ensure that the overall length of the glasses leg meets the wearing standard. At the same time, the front leg and the rear leg are connected by a hinge, which can also ensure that the glasses as a whole take up less space when stored. On the basis of this structure, compared with the prior art, the difference of this case is that when the two are flipped around the hinge so that the protrusion is embedded in the receiving groove, the glasses leg as a whole is in a fully unfolded state. At this time, the latch on the protrusion rotates with the protrusion and is embedded in the receiving groove. When the inner wall of the receiving groove is squeezed, The groove wall of the accommodating groove is slightly pushed outward and deformed, so that the pin enters the limiting groove. In this state, the end of the pin is limited by the accommodating groove, so that the glasses legs formed by the hinged connection of the front legs and the rear legs can always be kept in the unfolded state, thereby ensuring the structural stability of the glasses legs in the unfolded state. At this time, when the user wears the glasses, since the glasses legs can be kept in the unfolded state as a whole, there is no need for the user to use both hands to spread the two glasses legs outward, and the glasses can be worn by holding any one of the glasses legs with one hand, thereby ensuring the convenience of wearing by the user.
[0008] In the foldable glasses leg, a clearance groove is provided on the inner wall of the receiving groove, and the clearance groove corresponds to the position of the bayonet. By setting the clearance groove, the bayonet can be made to make way for the bayonet, so as to ensure the bayonet can be smoothly inserted into the receiving groove, and avoid excessive interference causing the receiving groove wall or the bayonet end to wear too quickly.
[0009] In the above-mentioned foldable eyeglass leg, the receiving groove is a strip groove and passes through the upper and lower side surfaces of the end of the front leg, the limiting grooves are provided on the inner walls on both sides of the receiving groove, and the giving way grooves are provided on the inner walls on both sides of the notch of the receiving groove, the protruding part is in the shape of a quadrangular prism, the protruding part is provided with a connecting hole that passes through the side walls on both sides, the bayonet is engaged in the connecting hole, and both ends of the bayonet are protruding from the side walls of the protruding part. Through this arrangement, when the front leg and the rear leg rotate around the hinge, the protruding part is prevented from getting stuck when it is not fully embedded in the receiving groove, and at the same time, the two ends of the slot are limited by the two receiving grooves, thereby improving the stability of the bayonet when it is limited in the limiting groove.
[0010] In the above-mentioned foldable eyeglass leg, one end of the front leg with the receiving groove has two spaced front hinges, and the two front hinges are located at the lower edge of the front leg, and the lower end of the protruding portion has a rear hinge, and the rear hinge is located between the two front hinges and is hinged by a hinge pin. The front leg and the rear leg are hinged by the front hinge, the rear hinge and the hinge pin, and the front hinge and the rear hinge are both arranged downward, so that the rotation angle of the front leg and the rear leg around the hinge can be effectively guaranteed. When used later, the two can be turned upward around the hinge, so that the protruding portion is completely embedded in the receiving groove to unfold the eyeglass leg.
[0011] In the above-mentioned foldable glasses leg, the connection hole is formed on the outer wall of the protruding part near the upper end, and each of the limiting grooves extends from the upper end of the receiving groove wall to the lower end of the receiving groove wall. As a result, the arrangement position of the bayonet is more reasonable relative to the hinge of the front leg and the rear leg, while ensuring the rotation range of the front leg and the rear leg around the hinge and preventing interference.
[0012] In the above-mentioned foldable glasses leg, both ends of the bayonet are chamfered along the circumferential direction to form an arc surface transition, so as to ensure that the bayonet can be inserted more smoothly.
[0013] Compared with the prior art, the foldable glasses leg has the following advantages:
[0014] When the front leg and the rear leg rotate around the hinge to put the temples in the unfolded state, the protrusion on the rear leg is embedded in the accommodating groove of the front leg, and the bayonet assembled on the protrusion is inserted into the limiting groove opened on the groove wall of the accommodating groove. The limiting effect of the groove wall on the bayonet pin makes the temples remain stable in the unfolded state, effectively ensuring that the user is more convenient to wear.

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0022] like Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, the foldable glasses leg comprises a front leg 1 and a rear leg 2 in the form of a long strip, the front end of the front leg 1 is used to be hinged with the frame, and a square-shaped fixing block is integrally formed at the rear end of the front leg 1, and a T-shaped protruding block is integrally formed at the front end of the rear leg 2. Specifically, the front side of the fixing block is integrally formed with the rear end of the front leg 1, and a receiving groove 11 penetrating through the upper and lower ends of the fixing block is provided on the outer wall of the rear side, and the part of the protruding block protruding outward is a protruding portion 21, and the protruding portion 21 is specifically a quadrangular It is columnar, with a front hinged portion 12 formed at the bottom of the connecting block and on both sides of the accommodating groove 11, and a rear hinged portion 213 formed at the lower end of the protruding portion 21. Both the front hinged portion 12 and the rear hinged portion 213 are provided with openings, and the rear hinged portion 213 extends into the accommodating groove 11 and is located between the two front hinged portions 12, and a hinge pin is sequentially passed through the holes opened on the front hinged portion 12 and the rear hinged portion 213, so that the front leg 1 is hinged to the rear leg 2 to form a complete glasses leg.
[0023] like Figure 4 As shown, limiting grooves 111 extending from the upper end of the receiving groove 11 to the middle of the receiving groove 11 are provided on the groove walls on both sides of the receiving groove 11, and the groove walls of each limiting groove 111 are arc-shaped. At the same time, the groove walls on both sides of the groove opening of the receiving groove 11 are provided with clearance grooves 112 corresponding to the positions of the limiting grooves 111, and the groove bottom walls of each clearance groove 112 are inclined outwards, as shown in FIG. Figure 5 As shown, a connecting hole 212 is horizontally opened at the upper end of the protruding portion 21 and passes through the outer walls on the left and right sides of the protruding portion 21. A bayonet 211 is installed in the connecting hole 212 in a plug-in manner. Both ends of the bayonet 211 protrude from the two end ports of the connecting hole 212 and the circumferential outer wall is clamped with the inner wall of the connecting hole 212. The edges of both ends of the bayonet 211 are chamfered in an arc shape along the circumferential direction. In addition, in order to prevent the front leg 1 and the rear leg 2 from getting stuck during the rotation around the hinge, the outer walls of the protruding blocks on both sides of the rear hinge 213 are arranged to be concave arc surfaces, thereby avoiding interference between the protruding blocks and the front hinge 12, thereby preventing the occurrence of jamming.
[0024] Principle of use: When the user applies force to the hind leg 2, the hind leg 2 rotates upward around the hinge with the front leg 1, and finally until the protrusion 21 is embedded in the receiving groove 11. During this process, under the guidance of the two give-way grooves 112, the two ends of the bayonet 211 can enter the receiving groove 11 along its groove wall. Under continuous force, the two ends of the bayonet 211 can slightly push the groove wall of the receiving groove 11 outward, so that the bayonet 211 rotates with the hind leg 2 and finally embeds into the limit groove 111. At this time, the protrusion 21 The front outer wall is completely in contact with the bottom wall of the accommodating groove 11, and at the same time, the groove wall edge of the limiting groove 111 limits the two ends of the pin 211, so that the front leg 1 and the rear leg 2 can always remain in this state without rotating, thereby ensuring that the glasses legs can be folded and stored, and ensuring that the structure remains stable in the unfolded state, and then one of the glasses legs can be held in one hand for wearing. Conversely, when folding, the user only needs to push the rear leg 2 in the opposite direction to make the pin 211 escape from the limiting groove 111.
