Abstract
The utility model relates to a glasses leg folding device, which comprises a leg hinge connected with the glasses leg, a frame hinge connected wit the glasses frame, a screw that is connected with the leg hinge and the frame hinge and plays the function of a hinge joint axle, a spring and a ball bearing, wherein the round hole in the hinge tooth of the frame hinge is articulated with a sleeve; a sleeve is articulated onto the straight body of the screw; the height of the sleeve wall is no less than the thickness of the hinge tooth of the frame hinge and at the same no more than the straight-line distance between the inner surfaces of the two hinge teeth of the leg hinges. Thereby the screw on the catapult hinge can be used for a long time and is not easy to fall off. Moreover, even in the case the screw is screwed down, the hinge teeth of the frame hinge and the leg frame do not contact and rub together.
Description
Technical field:
The present invention relates to a kind of spectacle frame device, especially a kind of leg of spectacles folding device.
Background technology:
At present, the employed leg of spectacles folding device of the spectacle frame of selling on the market is after assembling, the leg hinge that connects with leg of spectacles is when carrying out hinge-coupled with the frame hinge that connects with spectacle-frame, because frame hinge is directly to be enclosed within on the straight body position of screw of jointed shaft effect, so when normal the connection, about more than 200 times the time by opening and closing when folding device, screw will get loose.If for preventing to get loose with the screw overtorquing, will make the frame hinge give birth to paste and rub with the hinge tooth and hair of leg hinge, cause the opening and closing of folding device not smooth.In order to address this problem, the screw that some folding device is used is manufactured left-hand thread and right-hand thread respectively, but this has caused trouble in manufacture process and the installation process and situation about easily obscuring again.
Summary of the invention:
The object of the present invention is to provide a kind of leg of spectacles folding device, make that the screw that plays the jointed shaft effect on the leg of spectacles folding device can use for a long time, difficult drop-off, need not specially screw to be manufactured left-hand thread and right-hand thread, thereby be convenient to make and install, even under the situation of tighten the screws, the hinge tooth of frame hinge and leg hinge can not take place to paste yet and rub.
In order to realize purpose of the present invention, this leg of spectacles folding device, comprise leg hinge, the frame hinge that connects spectacle-frame that connects leg of spectacles, the screw that plays the jointed shaft effect, spring and the ball that connects leg hinge and frame hinge, movable sleeve is connected to a sleeve in the circular hole on frame hinge hinge tooth, sleeve is actively socketed on again on the straight body position of screw, the height of sleeve wall is not less than the thickness of frame hinge hinge tooth, is not higher than the air line distance between leg hinge two hinge tooth inside surfaces simultaneously again.
Sleeve can be columniform, also can be prismatic.
Adopt the leg of spectacles folding device of technique scheme, owing between hinge tooth and screw, added sleeve, and sleeve has certain height, even can not get loose through 10,000 opening and closing so reached the screw that makes on the spring hinge yet, and avoided specially screw being manufactured the restriction of left-hand thread and right-hand thread, thereby be convenient to make and install, even simultaneously under the situation of tighten the screws, the hinge tooth of frame hinge and leg hinge can not take place to paste yet and rub, and has guaranteed spring hinge opening and closing swimmingly.
Description of drawings:
Fig. 1 is the axial cut-open view of amplification of the sleeve of the utility model leg of spectacles folding device;
Fig. 2 is the side partial sectional view of the utility model leg of spectacles folding device when stretching out;
Fig. 3 is the front perspective view of the utility model leg of spectacles folding device when amounting to.
Embodiment:
Below in conjunction with drawings and Examples the present invention is described in detail:
With reference to figure 1, Fig. 2 and Fig. 3, this leg of spectacles folding device of the present invention comprises leg hinge 2, the frame hinge 6 that connects spectacle-frame that connects leg of spectacles, the screw that plays the jointed shaft effect 7, spring 9 and the ball 10 that connects leg hinge 2 and frame hinge 6.Movable sleeve is connected to a columniform sleeve 5 in the circular hole on the hinge tooth 3 of frame hinge 6, sleeve 5 is actively socketed on again on the straight body position of screw 7, the height of sleeve wall 1 is not less than the thickness of the hinge tooth 3 of frame hinge 6, is not higher than the air line distance between hinge tooth 4,8 inside surfaces of leg hinge 2 simultaneously again.
When assembling this device, the leg of earlier spring 9 being packed into cuts with scissors in the spring chamber of 2 inside, between the hinge of again ball 10 being packed into the tooth 4,8 and prop up spring 9 corresponding ends, then sleeve 5 is inserted in the circular hole on the hinge tooth 3 of frame hinge 6, and will cut with scissors tooth 3 and insert between the hinge tooth 4,8, the top of hinge tooth 3 withstands on the ball 9, and screw 7 orders are passed circular hole and the sleeve 5 on the hinge tooth 8, be screwed onto at last in the screw on the hinge tooth 4, the hinge tooth 3 of frame hinge 6 can directly not touch with the straight body position of screw 7 mutually.
Except the above embodiments, sleeve 5 also can be prismatic.
In a word, every sleeve that utilizes is separated screw and the leg of spectacles folding device that with the screw is the hinge tooth of jointed shaft rotation, all drops within the protection domain of the present utility model.
