Abstract
The utility model discloses an elasticity hinge, including first articulated elements of mutual articulated and second articulated elements, the lateral wall of first articulated elements one end is equipped with the recess to the recurve, the bottom surface of recess is provided with the articulated shaft, the second articulated elements is provided with the elasticity articulated jib, the tail end of elasticity articulated jib bending forward is provided with the pothook, the recess with the head end of second articulated elements cooperatees, the articulated shaft with pothook looks joint. This structural design, the structure is simple relatively, need not adopt hinge screwed connection, light in weight, and do not need the welding, and then can effectively avoid because welding strength scheduling problem and the picture frame quality problems that arouse.
Description
Technical field
The utility model relates to frame hinge technical field, particularly relates to a kind of elastic hinge.
Background technology
Along with the development of society, the raising of people's life, educational level, the expansion of sight protection work, the status of glasses in people's life is more and more important, and people are wearing spectacles due to a variety of causes.And for most lens wearer, glasses are not only both artistic and practical, more want light comfortable.Especially for the people worn glasses for a long time, comfortableness more seems particularly important.And determine that one of key factor of glasses comfortableness is the connection of elastic hinge.Existing elastic hinge for eyeglasses complex structure, technique is loaded down with trivial details, and cost is high, heavy, need welding, and weld strength affects the quality of glasses, even directly determines the serviceable life of glasses.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, lightly, is convenient to the elastic hinge assembled.
For reaching this object, the utility model by the following technical solutions:
A kind of elastic hinge, comprise the first articulated elements and the second articulated elements that are hinged, the sidewall of described first articulated elements one end is arranged with groove backward, and the bottom surface of described groove is provided with jointed shaft; Described second articulated elements is provided with elastic hinge joint arm, and the tail end bend forward of described elastic hinge joint arm is provided with grab, and described groove matches with the head end of described second articulated elements, described jointed shaft and the clamping of described grab phase.
Wherein, the bottom surface of described groove axially offers breach, and between the two side of described breach, radial direction is provided with described jointed shaft.
Wherein, the sidewall of described second articulated elements head end offers elongated slot, in described elongated slot, be axially provided with described elastic hinge joint arm.
Wherein, the inside surface of described grab and the bottom surface of described jointed shaft tangent.
Wherein, described first articulated elements and the second articulated elements all adopt stainless steel substrates or beta titanium sheet to process one-body molded.
Wherein, described groove matches with the head end of described second articulated elements.
The beneficial effects of the utility model: the utility model comprises the first articulated elements and the second articulated elements that are hinged, the sidewall of described first articulated elements one end is arranged with groove backward, and the bottom surface of described groove is provided with jointed shaft; Described second articulated elements is provided with elastic hinge joint arm, and the tail end bend forward of described elastic hinge joint arm is provided with grab, and described groove matches with the head end of described second articulated elements, described jointed shaft and the clamping of described grab phase.This structural design, structure is relatively simple, does not need to adopt HINGE SCREWS to connect, lightweight, and does not need welding, and then effectively can avoid the picture frame quality problems that cause due to problems such as weld strengths.
Accompanying drawing explanation
Fig. 1 is the exploded view of a kind of elastic hinge of the utility model.
Fig. 2 is the wiring layout of a kind of elastic hinge of the utility model.
Structural representation when Fig. 3 is the first articulated elements and the assembling of the second articulated elements in Fig. 2.
Fig. 4 is structural representation when the second articulated elements upwards rotates relative to the first articulated elements in Fig. 2.
In figure: 1. the first articulated elements, 11. grooves, 111. jointed shafts, 112. breach, 2. the second articulated elements, 21. elastic hinge joint arms, 211. grabs, 22. elongated slots.
Embodiment
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing 1 to accompanying drawing 4 by embodiment.
As shown in Figure 1, a kind of elastic hinge, comprise the first articulated elements 1 and the second articulated elements 2 be hinged, the sidewall of described first articulated elements 1 one end is arranged with groove 11 backward, and the bottom surface of described groove 11 is provided with jointed shaft 111; The head end of described second articulated elements 2 is provided with elastic hinge joint arm 21, the tail end bend forward of described elastic hinge joint arm 21 is provided with grab 211, described groove 11 matches with the head end of described second articulated elements 2, described jointed shaft 111 and the clamping of described grab 211 phase.
Preferably, the bottom surface of described groove 11 axially offers breach 112, between the two side of described breach 112, radial direction is provided with described jointed shaft 111, the sidewall of described second articulated elements 2 head end offers elongated slot 22, axially described elastic hinge joint arm 21 is provided with in described elongated slot 22, the inside surface of described grab 211 and the bottom surface of described jointed shaft 111 tangent, described groove 11 matches with the head end of described second articulated elements 2.
Said structure designs, when the first articulated elements 1 and the second articulated elements 2 assemble, as shown in Figure 3, first elastic hinge joint arm 21 one end with grab 211 is lifted, the head end of the second articulated elements 2 is matched with groove 11, inserted in breach 112 elastic hinge joint arm 21 one end with grab 211, now grab 211 matches with jointed shaft 111, and then forms assembly as shown in Figure 2 simultaneously.
The first articulated elements 1 after assembling and the second articulated elements 2 are as shown in Figure 4, the head end of the second articulated elements 2 matches with the groove 11 of the first articulated elements 1 and can avoid the opposing oscillatory of two web members in Fig. 2 paper plane, the second articulated elements 2 can relative to the first articulated elements 1 as Fig. 4 upwards or rotate flexibly downwards as Fig. 3.This structural design, provide a kind of without screw light and handy antihunting super-elasticity hinge, structure is relatively simple, do not need HINGE SCREWS, lightweight, hinge is directly made from the accessory be attached thereto, do not need welding, thus avoid the glasses quality problems because weld strength etc. causes.It can realize production in enormous quantities, outward appearance is light and handy.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, and these modes all will fall within protection domain of the present utility model.
