Abstract

The utility model relates to a spectacle arm connecting mechanism capable of rotating 360 degrees, which belongs to the technical field of the spectacle frame. The spectacle arm connecting mechanism comprises end piece hinges and spectacle arm bodies and is characterized in that one end of arm cores penetrates through the central through holes of the spectacle arm bodies and a connecting block to be articulated with the end piece hinges, springs are sleeved on the arm cores in the central through holes of the spectacle arm bodies, and are limited through a limit device, and the tail needle parts of the arm cores are exposed out of the spectacle arm bodies. The utility model has the advantages that firstly, the spectacle arm connecting mechanism is capable of rotating 360 degrees, decorative patterns or designs at the inner side of the spectacle arm bodies of the spectacle arms can be converted to the outer surface to form a new spectacle style, secondly, the spectacle arm connecting mechanism has the function of a spring bow, an elastic device is arranged in the middle of the spectacle arm bodies, thus the mass center of the spectacles is shifted backward, and the wearer of the spectacles are comfortable, thirdly, the structure is simple, and the outline is artistic, thus the spectacle arm connecting mechanism is suitable for matching with spectacle arms of various spectacles.

Description

Earpiece bindiny mechanism that can 360 ° of rotations

Technical field:

The utility model belongs to the spectacle frame technical field, refers in particular to a kind of earpiece bindiny mechanism that can 360 ° of rotations.

Background technology:

In existing glasses, earpiece is made up of village head hinge and pin body two parts of being hinged, earpiece after bending can only be used at a side and the glasses of people's eyes, weak point is: the one, and one of ornament that earpiece is worn as people, have only the pattern of external one side just can play decoration function, want to adjust the earpiece of different decorative effects, must change another pair glasses and could realize; The 2nd, after being hinged, most village head hinge and pin body do not possess the catapult function, and cause two earpieces after bending loose excessively, just glide easily, can make eyeglass wearer uncomfortable during tension again, even can crush cheek; The 3rd, also have in the hinged place of the front portion of earpiece to be provided with elastic device, to realize the function of elastic glasses foot, but because eyeglass, mirror holder, pin body front portion and elastic device are all concentrated and the front portion of glasses, cause the mass cg reach of glasses, make that the bridge of the nose load-bearing of eyeglass wearer is excessive also can to make the eyeglass wearer discomfort.

Summary of the invention:

The purpose of this utility model provides a kind ofly promptly to be had catapult function, comfortable wearing, can make earpiece do the earpiece bindiny mechanism of 360 ° of rotations again.

The utility model be achieved in that can 360 ° of rotations earpiece bindiny mechanism, include village head hinge, pin body, it is characterized in that: central through hole and village head that an end of pin core passes pin body and contiguous block successively cut with scissors hinged, be arranged with spring on the pin core in the central through hole of pin body, and spacing by stop means, the tailpin of pin core partly exposes outside the pin body.

Pin in the junction of pin body and contiguous block is provided with positioning boss or detent on one's body, pin body and the contiguous block of the junction of contiguous block are provided with detent or the positioning boss that cooperates the location with the pin body, in the arranged outside of the central through hole of the other end of contiguous block 90 ° back cushion are arranged.

Spring is meant by stop means is spacing: be arranged with front pad, spring and back pad successively at the middle part of pin core, front pad is spacing by the boss on the pin core, and back pad is by making the distortion of pin core spacing, and front pad is simultaneously spacing by pin positive stop lug boss on one's body again.

The compression displacement of spring can make the positioning boss on pin body and the contiguous block break away from detent, and can make the pin body do 360 ° rotation with respect to contiguous block.

The outstanding compared to existing technology advantage of the utility model is:

1, earpiece of the present utility model can be done 360 ° rotation, can be easily with the decorative pattern of the pin body inboard of earpiece or model transformation to outside surface, form a kind of new glasses style.

2, earpiece of the present utility model possesses the catapult function, because elastic device is arranged on the middle part of pin body, moves after making the mass cg of glasses, makes the comfortable wearing of eyeglass wearer;

3, of the present utility model simple in structure, good looking appearance suits to do the supporting use of earpiece on various glasses.

Embodiment:

With specific embodiment the utility model is further described below, referring to Fig. 1-7:

Earpiece bindiny mechanism that can 360 ° of rotations, mainly by village head hinge 1, pin body 3, pin core 4, front pad 5, spring 6, back pad 7, screw is formed, one end of preceding single tooth 44 of pin core 4 passes the central through hole 31 of pin body 3 and contiguous block 2 successively, 32, link together with screw with two teeth of village head hinge 1, the path place at the middle part of the pin core 4 in the central through hole 31 of pin body 3 is arranged with front pad 5 successively, spring 6 and back pad 7, front pad 5 is spacing by the boss 43 on the pin core 4, back pad 7 is by making the flat distortion of pin core 4 bats spacing, front pad 5 is spacing by the positive stop lug boss 311 in the central through hole 31 of pin body 3 again simultaneously, and the tailpin 42 of pin core 4 exposes outside pin body 3.

Pin body 3 is provided with positioning boss 33 with the pin body 3 of the junction of contiguous block 2, pin body 3 is provided with the detent 21 that cooperates the location with pin body 3 with the contiguous block 2 of the junction of contiguous block 2, side at the central through hole 22 of the other end of contiguous block 2 is provided with 90 ° back cushion 23, penetrate groove 112 when the concave station 113 that termination 11 is provided with mounting hole 111, cooperate with back cushion 23 and single tooth 44 are connected with termination 11, single tooth 44 and termination 11 usefulness screws 8 and screw thread are rotationally connected.

The compression displacement of spring 6 can make the positioning boss 33 on pin body 3 and the contiguous block 2 break away from detents 21, and can make pin body 3 do 360 ° rotation with respect to contiguous block 2.

Use of the present utility model, referring to Fig. 1-7: two village of the present utility model heads hinges 1 are respectively installed on the spectacle frame, adjust earpiece and eye wear person's the distance and the fit shapes of pin core 4 and eye wear person ear, eye wear person with respect to big cheek, because the elastic force of spring 6, can make village head hinge 1 with respect to the certain angle of pin body 3 outside expansibles, to adapt to wearer's cheek; When eye wear person's desire with the decorative pattern of pin body 3 inboards of earpiece or model transformation during to outside surface, only need hold contiguous block 2 and pin body 3 respectively and to two laybacks with two hands, the detent 21 that positioning boss 33 on the pin body 3 is broken away from the contiguous block 2, Rotate 180 degree again, can form a kind of new glasses style with the decorative pattern of pin body 3 inboards of earpiece or model transformation to outside surface.

The foregoing description only is one of preferred embodiment of the present utility model; be not to limit practical range of the present utility model with this; so: all equivalences of doing according to shape of the present utility model, structure, principle change, and all should be covered by within the protection domain of the present utility model.
