DETAILED DESCRIPTION

[0031] The utility model will be further described below in combination with the drawings and specific embodiments, and the following description is only exemplary and does not limit the protection scope of the utility model.

[0032] Embodiment one:

[0033] As Figures 1-5 shown, a novel glasses leg mechanism comprises a pile head 1, a rotating rod 2, an elastic pressing block 3, a positioning column 4 and a glasses leg 5.

[0034] Specifically, the hinge hole 11 is arranged at the rear end of the pile head 1 and extends through left and right sides, and a hinge clamping column 12 is formed at the rear side of the hinge hole 11; the first clamping groove 21 is arranged at the front end of the rotating rod 2 and extends through upper and lower sides with an open front end, and the positioning protrusions 22 and the hinge clamping groove 23 are arranged at the inner side of the first clamping groove 21 in sequence from front to back; the hinge clamping column 12 is inserted into the first clamping groove 21, the hinge clamping column 12 is embedded in the hinge clamping groove 23 to form a rotating fulcrum, and the positioning protrusions 22 are clamped into the hinge hole 11; it should be noted that the rotating rod 2 or the positioning protrusions 21 itself has a certain deformation elasticity, so as to ensure the convenience of installation; the elastic pressing block 3 is clamped on the rotating rod 2 and is limited by the positioning column 4 arranged on the rotating rod 2, and the front end inner side of the elastic pressing block 3 is matchably attached to the rear end outer side of the pile head 1; in the embodiment, the front end of the temple 5 is matchably connected to the rear end of the elastic pressing block 3.

[0035] In use, when the temple 5 is opened, the front end inner side of the elastic pressing block 3 can remain attached to the rear end outer side of the pile head 1 and form a surface contact; when the temple 5 is folded, the rotating rod 2 can be rotated around the hinge clamping column 12, and the positioning protrusions 22 continue to be inserted into the hinge hole 11 outward, at the same time, the elastic pressing block 3 is rotated (specifically, the rear end surface of the pile head 1 can be used as a fulcrum to rotate), and finally, when the temple 5 is folded, the front end of the elastic pressing block 3 is rotated outward by a certain distance, so that the elastic pressing block 3 and the rear end of the pile head 1 cannot remain in the surface contact state of mutual attachment.

[0036] In summary, the cooperation between the pile head 1, the rotating rod 2, the elastic pressing block 3, the positioning column 4 and the temple 5 can form a screw-free glasses leg mechanism, which has a simple and reasonable overall structure and is easy to assemble, and there is no risk of screw loosening after long-term use, which is beneficial to the wearing of glasses. When the temple 5 is opened, the attachment (i.e. surface contact) between the front end of the elastic pressing block 3 and the rear end of the pile head 1 can be used to ensure the stability of the elastic pressing block 3 and the rotating rod 2, specifically, since the elastic pressing block 3 has elasticity, the stable attachment between the front end of the elastic pressing block 3 and the rear end of the pile head 1 can be maintained, and the temple 5 is positioned and is not prone to loosening, and when the temple 5 is folded, the temple 5 can be directly pushed inward, so that the rotating rod 2 rotates around the hinge clamping column 12, and the elastic pressing block 3 and the temple 5 are driven to rotate inward, so as to achieve the effect of folding the temple 5.

[0037] As Figures 1-5As shown, preferably, in order to facilitate the installation of the elastic pressing block 3, a left-right penetrating strip-shaped sleeve hole 31 is arranged in the middle of the elastic pressing block 3; the elastic pressing block 3 is sleeved on the outer side of the rotating rod 2 through the strip-shaped sleeve hole 31, and the rear end of the elastic pressing block 3 is positioned; the positioning column 4 is installed on the outer side of the rotating rod 2 and abuts on the outer side of the middle of the elastic pressing block 3, so that the middle of the elastic pressing block 3 maintains a tendency to deform inward, thereby enabling the inner side of the front end of the elastic pressing block 3 to maintain sufficient adhesion with the outer side of the rear end of the post head 1, avoiding loosening of the two to cause loosening of the glasses legs 5, that is, this design ensures the use effect of the glasses legs 5 when opened. Therefore, through the above arrangement, the positioning column 4 can stably connect the elastic pressing block 3 with the rotating rod 2 and the post head 1, thereby ensuring the use effect of the glasses legs 5.

[0038] As shown in the drawings, Figure 4 As shown, preferably, in order to stably position the elastic pressing block 3, an outward and rearward opening positioning step 24 is arranged at the rear end of the rotating rod 2; after the elastic pressing block 3 is sleeved on the outer side of the rotating rod 2, the rear end of the elastic pressing block 3 can be matched and clamped on the positioning step 24 through the rear end of the strip-shaped sleeve hole 31. Therefore, through the above arrangement, the positioning step 24 can limit the rear end of the elastic pressing block 3, preventing it from coming out, and since the front end of the elastic pressing block 3 is limited by the post head 1 and the middle of the elastic pressing block 3 is limited by the positioning column 4, through the above three positions limiting the inner sides of the front and rear ends of the elastic pressing block 3 and the outer side of the middle of the elastic pressing block 3, the position of the elastic pressing block 3 can be conveniently and stably fixed, so that it is not easy to loosen, thereby ensuring the use effect between the elastic pressing block 3 and the post head 1.

[0039] As shown in the drawings, Figures 1-5 As shown in the drawings, in this embodiment, the elastic pressing block 3 is in an outward convex arc shape, so that when the elastic pressing block 3 is limited by the positioning column 4, the elasticity can be maintained, that is, the adhesion between the elastic pressing block 3 and the rear end of the post head 1 can be maintained, and finally the glasses legs 5 are not easy to naturally fold in the open state.

[0040] As shown in the drawings, Figures 1-5 As shown, preferably, a positioning hole 26 for installing the positioning column 4 is arranged in the middle of the outer side of the rotating rod 2; the positioning column 4 is matched and installed in the positioning hole 26. Specifically, an installation block 25 protrudes outward on the middle of the outer side of the rotating rod 2; the positioning hole 26 is arranged on the installation block 25.

[0041] As shown in the drawings, Figures 1-5 More specifically, the positioning hole 26 penetrates the upper and lower end faces of the rotating rod 2, and the positioning column 4 is interference-fitted in the positioning hole 26. Therefore, through the above arrangement, the positioning column 4 can be conveniently assembled, so that it is not easy to loosen.

[0042] As Figures 1-5 shown, in addition, in order to guarantee the stability of the rotating rod 2 after installation, a second clamping groove 13 which is through left and right and open at the rear end is also arranged on the rear end surface of the pile head 1; the hinged clamping column 12 is located between the hinged hole 11 and the second clamping groove 13; when the hinged clamping column 12 is inserted in the first clamping groove 21, the rotating rod 2 is also matched and clamped at the second clamping groove 13 through the first clamping groove 21.

[0043] As Figures 1-5 shown, a clearance hole 14 which is through left and right and communicates with the hinged hole 11 is also arranged on the rear end of the pile head 1; when the glasses leg 5 is in the open state, the front end cover of the elastic pressing block 3 is arranged on the clearance hole 14, and an arc surface 32 corresponding to the clearance hole 14 is also arranged on the inner side of the front end surface of the elastic pressing block 3, and the length between the upper and lower sides of the arc surface 32 is greater than the length between the upper and lower sides of the clearance hole 14. Therefore, by arranging the clearance hole 14, the contact area between the inner side of the front end surface of the elastic pressing block 3 and the pile head 1 can be reduced, and the possible wear between the middle part of the inner side of the front end surface of the elastic pressing block 3 and the pile head 1 can be reduced to a certain extent, so that the middle part of the inner side of the front end surface of the elastic pressing block 3 remains intact, and the appearance integrity is better.

[0044] Preferably, in order to facilitate production, the glasses leg 5 and the elastic pressing block 3 are integrally formed. In addition, the glasses leg 5 and the elastic pressing block 3 are both made of metal.

[0045] In the embodiment, the pile head 1 is in the shape of "L" so that it can be directly connected with the frame, or it can be integrally formed with the frame.

[0046] Embodiment two:

[0047] As Figures 6-8 shown, the difference between the embodiment and the embodiment one is that in the embodiment, the front end of the glasses leg 5 is matched and connected with the rear end of the rotating rod 2. In addition, in the embodiment, the glasses leg 5 is integrally formed with the rotating rod 2 and both are made of metal, so that the production is facilitated. Since the above structure is basically similar to the structure in the embodiment one in terms of function and use, the difference is only in the setting position of the glasses leg 5, therefore, it will not be repeated here.

[0048] The utility model is not limited to the above-mentioned embodiments, if various modifications or deformation of the utility model do not deviate from the spirit and scope of the utility model, if these modifications and deformation belong to the claim and equivalent technical scope of the utility model, then the utility model also intends to include these modifications and deformation.
