Description

Technical Field

[0001] The utility model relates to the technical field of glasses structures, and more specifically to a spring-type glasses frame. Background Art

[0002] In the manufacture and design of glasses, the connection structure between the frame and the temples is the core element to ensure the overall stability and comfort of the glasses. The traditional connection method between the frame and the temples is usually assembled with small screw fasteners. Although this connection method is relatively simple in structure, it also has certain defects:

[0003] (1) It is difficult to adjust the tightening degree of screw fasteners, and it is often difficult to achieve the best tightening effect, which affects wearing comfort;

[0004] (2) As the glasses are frequently folded and unfolded, the locking degree of the screw fasteners will gradually loosen, and may even cause the screw fasteners to fall off. Once the screws become loose or fall off, it is difficult to quickly find suitable tools for repair because the repair tools required for small screw fasteners are not common, thus affecting the normal use of the glasses.

[0005] Therefore, how to provide a spring-type eyeglass frame with a simple structure, without the need for screw fasteners, and capable of ensuring stability is a problem that technical personnel in this field urgently need to solve. Utility Model Content

[0006] In view of this, the utility model provides a spring-type eyeglass frame, aiming to solve the above technical problems.

[0009] One end of the double-piece ear seat is fixed on the temple, and the other end is arranged toward the temple mounting plate, and a radial through groove is opened on the side wall of the temple;

[0010] The connecting shaft is fixed to one end of the temple mounting plate away from the mirror frame and is rotatably connected to the double-piece ear seat to realize the unfolding and folding of the temple;

[0011] The elastic connecting piece passes through the radial through slot and is clamped in the double-piece ear seat. One end of the elastic connecting piece abuts against the temple mounting plate, and the other end of the elastic connecting piece is clamped on the outer side of the radial through slot.

[0012] Through the above technical solution, the utility model provides a spring-type eyeglass frame, which utilizes the deformation and elastic restoring force of the elastic connecting piece to stably and reliably hook the frame and the temple, and uses the thickened end surface of the temple mounting plate to provide abutment positioning for the elastic connecting piece after the temple is folded, thereby improving the stability after folding. The utility model has a simple structure, and by using an elastic connecting piece to replace the structural setting of the traditional screw fastener, it solves the technical problem of the inconvenience of repair of the screw fastener in the prior art, and ensures that the structural stability of the eyeglass frame can be guaranteed when the screw fastener is not used.

[0013] Preferably, in the above-mentioned spring-type eyeglass frame, the double-piece ear seat has a certain clamping force for the elastic connecting piece passing through the radial through groove, which can prevent the elastic connecting piece from escaping from the double-piece ear seat.

[0015] Preferably, in the above-mentioned spring-type eyeglass frame, an end of the double-piece ear seat away from the temple is provided with an axial hole, and the connecting shaft is fixed on the clamping plate and rotatably connected in the axial hole, so as to realize relative rotation between the temple and the frame and to realize the unfolding and folding of the temple.

[0016] Preferably, in the above-mentioned spring-type eyeglass frame, the distance between the two ear seats is greater than the width of the temple mounting plate. The structure is simple and stable, and when the temple is folded, a rotation space is provided for the temple mounting plate.

[0017] Preferably, in the above-mentioned spring-type eyeglass frame, the elastic connecting piece includes an integrally formed head section, body section and tail section; the head section is clamped at the radial through slot and is located on the outside of the temple, the connection between the head section and the body section passes through the radial through slot, the tail section and the body section are both located on the inside of the temple, and the tail section abuts against the temple mounting plate. The structure is simple and stable, and the deformation recovery force of the elastic connecting piece can be utilized.

[0018] Preferably, in the above-mentioned spring-type eyeglass frame, the length of the radial through slot is smaller than the width of the head section and larger than the width of the body section and the tail section, so that the head section of the elastic connecting piece is clamped on the outside of the radial through slot to prevent the head section from being inserted into the inside of the radial through slot.

[0019] Preferably, in the above-mentioned spring-type eyeglass frame, the elastic connecting piece is made of a metal material or a hard plastic material with elastic restoring force.

[0020] It can be seen from the above technical solutions that, compared with the prior art, the utility model discloses a spring-type eyeglass frame, which has the following beneficial effects:

[0034] One end of the double-piece ear seat 22 is fixed on the temple 20, and the other end is arranged toward the temple mounting plate 11. A radial through groove 23 is opened on the side wall of the temple 20;

[0035] The connecting shaft 12 is fixed to one end of the temple mounting plate 11 away from the frame 10 and is rotatably connected to the double-piece ear seat 22 to realize the unfolding and folding of the temple 20;

[0036] The elastic connecting piece 30 passes through the radial through slot 23 and is clamped in the double-piece ear seat 22 . One end of the elastic connecting piece 30 abuts against the temple mounting plate 11 , and the other end of the elastic connecting piece 30 is clamped on the outer side of the radial through slot 23 .

[0037] In order to further optimize the above technical solution, the temple mounting plate 11 is an L-shaped plate, and an extended clamping plate 13 is provided on the end surface of the L-shaped plate away from the frame 10 , and the clamping plate 13 is located in the double-piece ear seat 22 .
