Detailed Description
The present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1-5, an elastic hinge structure for connecting a pile head and a temple of an eyeglass comprises a pile head 1, a Z-shaped elastic sheet 2, a temple 3 and a pin 4, wherein the pile head 1 can be a single component or can be integrally formed with an eyeglass frame. Pile head 1 and mirror leg 3 are connected through pin 4 and are formed hinge structure. Z type shell fragment 2 is inserted and is established between mirror leg 3 and pile head 1 for Z type shell fragment 2 can turn up when mirror leg 3 rotates with pile head 1 (see fig. 4 and 5), thereby makes mirror leg 3 have certain elasticity space, and Z type shell fragment 2 can exert certain power to mirror leg 3 promptly, makes mirror leg 3 can adapt to different head shape size, improves the travelling comfort of head.
As shown in fig. 2 and 3, the end of the temple 3 connected to the pile head 1 is provided with a groove 31, and the groove 31 includes a first groove part 311 penetrating inside and outside and a second groove part 312 opened inside. The first groove portion 311 is provided with first pin holes 32 on both side walls. The connecting end 11 of the pile head 1 is provided with a second pin hole 12 corresponding to the first pin hole 32. The connecting end 11 of the pile head 1 is received in the first recess portion 312 and the pin 4 passes through the first pin hole 32 and the second pin hole 12 forming a hinge structure. The Z-shaped spring 2 comprises a first portion 21, a second portion 22 and an intermediate portion 23 therebetween. The first portion 21 and the intermediate portion 22 of the Z-shaped elastic piece 2 are received in the first groove portion 311, and the second portion 22 is received in the second groove portion 22. Wherein the first part 21 abuts the outside of the connecting end 11 of the pile head 1 and the intermediate part 22 is sandwiched between the connecting end 11 of the pile head 1 and the temple 3 (bottom of the second groove part 312). Therefore, when the temple 3 is rotated with respect to the pile head 1, the connecting end 11 of the pile head 1 rotates, turning the first portion 21 of the Z-shaped spring 2 outwards (as shown in fig. 4 and 5), and due to the elastic action, the temple 3 will have an inward force, avoiding that the temple 3 is too loose.
In the embodiment shown, the middle portion 23 of the profile strip 2 forms a right angle with the first portion 21 and an acute angle with the second portion 22. The acute angle is typically between 30-60 degrees, preferably 45 degrees.
In this embodiment, the connecting end 11 of the pile head 1 has a shoulder 111 of the same size as the first portion 21, so that the temple 3 is flush on its outer side after spreading. Likewise, the second portion is arranged such that it is flush with the inner side of the temple when received in the second groove portion. Therefore, the entire temples look beautiful.
The end face of the connecting end 11 of the pile head 1 is a circular arc surface in order to smoothly rotate the temple 3 and the pile head 1.
Preferably, the Z-shaped elastic sheet 3 is integrally formed, so that the mass production is facilitated and the cost is saved. The Z-shaped spring 3 may be made of a resilient metal material such as copper, zinc, titanium or an alloy thereof. Preferably, the Z-shaped spring 3 is made of titanium alloy, which is beautiful on one hand and long in service life on the other hand.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
