Abstract

The invention discloses a flexible hinge of glasses, which comprises a pile head, a moving part and a containing body. A cam is arranged at one end of the pile head, the end of the pile head is movably connected with the moving part through a pin, the moving part is movably arranged in the containing body, one end of the containing body contacts with the cam end of the pile head, the other end of the pile head is connected with a temple, the containing body is connected with the temple, the moving part is connected with a spring sheet serving as an energy storage element, the spring sheet is movably arranged in a sleeve in an inner cavity of the containing body, the pile head rotates relative to the moving part, the containing body horizontally moves forwards and backwards relative to the moving part by the aid of the cam end of the pile head, the containing body drives the sleeve to move so that the spring sheet moves relative to the sleeve and then deforms, and accordingly flexibility is generated. The flexible hinge is simple in process, operating efficiency can be improved, and mass production can be realized.

Description

Elastic hinge for eyeglasses

Technical field

The present invention relates to a kind of hinge that is used for glasses, be specifically related to a kind of elastic hinge for eyeglasses.

Background technology

Along with the development of society, the raising of people 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 because a variety of causes and wearing spectacles.And for most lens wearer, glasses are not only both artistic and practical, more want light comfortable.Especially for the people who wears glasses for a long time, it is particularly important that comfortableness more seems.And the key factor of decision glasses comfortableness is the connection of elastic hinge.

Existing elastic hinge for eyeglasses complex structure, technology is loaded down with trivial details, is not suitable for producing in enormous quantities.

Summary of the invention

Technical matters to be solved by this invention provides a kind of elastic hinge for eyeglasses, and it can realize producing in enormous quantities.

For solving the problems of the technologies described above, the technical solution of elastic hinge for eyeglasses of the present invention is:

Comprise pile crown, movement parts, hold body, an end of pile crown is a cam, and this end of pile crown flexibly connects through bearing pin and movement parts, and movement parts is movably set in to be held in the body; An end that holds body contacts with the cam end of pile crown; The other end of pile crown is connected with the mirror pin, holds body and is connected with the mirror leg; Movement parts connects the spring leaf as energy-storage travelling wave tube, and spring leaf is movably set in the sleeve that holds intracoelomic cavity; Pile crown rotates with respect to movement parts, and the cam end of pile crown makes holds body with respect to translation before and after the movement parts; Hold body drive sleeve and move, make spring leaf move, spring leaf is deformed, and produce elasticity with respect to sleeve.

Said spring leaf comprises two symmetrical planar chip springs, and the planar chip spring has radian; One end of two planar chip springs is fixedly connected, and the other end is separated from each other.

One end of said movement parts is provided with pin-and-hole, and the other end is provided with square groove; Square groove is fixedly connected with an end of said spring leaf.

The said body that holds is connected with the mirror leg through the welding lug.

The technique effect that the present invention can reach is:

Technology of the present invention is simple, can increase work efficiency, and realizes producing in enormous quantities.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:

Fig. 1 is the synoptic diagram of elastic hinge for eyeglasses of the present invention;

Fig. 2 is the synoptic diagram of movement parts of the present invention.

Description of reference numerals among the figure:

1 is pile crown, and 2 is movement parts,

3 for holding body, and 4 is bimetallic strip,

5 is sleeve, and 6 are the welding lug,

7 is square groove.

Embodiment

As shown in Figure 1, elastic hinge for eyeglasses of the present invention comprises pile crown 1, movement parts 2, holds body 3, and an end of pile crown 1 is a cam, and this end of pile crown 1 flexibly connects through bearing pin and movement parts 2, and movement parts 2 is movably set in to be held in the body 3; An end that holds body 3 contacts with the cam end of pile crown 1, and to form cam secondary with holding body 3 for the cam end of pile crown 1;

As shown in Figure 2, an end of movement parts 2 is provided with pin-and-hole, is used to connect pile crown 1; The other end of movement parts 2 is provided with square groove 7, and square groove 7 internal fixation are provided with spring leaf 4; Spring leaf 4 is as energy-storage travelling wave tube;

Spring leaf 4 is movably set in the sleeve 5, and sleeve 5 is fixedly set in the inner chamber that holds body 3; Sleeve 5 is used to limit the movement locus of spring leaf 4;

Spring leaf 4 comprises two symmetrical planar chip springs, and the planar chip spring has radian; One end of two planar chip springs is fixedly connected, and the other end is separated from each other;

The other end of pile crown 1 is connected with the mirror pin; Holding body 3 is connected with the mirror leg through welding lug 6.

Pile crown 1 is rotated with respect to movement parts 2, and the cam end of pile crown 1 makes holds body 3 with respect to movement parts 2 front and back translations; Hold body 3 drive sleeves 5 and move, make spring leaf 4 move, spring leaf 4 is deformed, and produce elasticity with respect to sleeve 5.

The glasses that adopt the present invention to connect are worn more comfortable.
