Description

Technical Field

[0001] The utility model belongs to the technical field of glasses, and in particular relates to a pair of fast-turning glasses. Background Art

[0002] There are many kinds of glasses on the market, among which glasses with flip function mainly include flip glasses with a shaft in the middle, flip-up glasses with two rotating shafts on the top of the glasses, and flip-hanging glasses with clip structures. The common feature is that they are fixed at one or more hinge positions by a rotating shaft and a shaft sleeve with a certain over-matching, so the shaft sleeve and the rotating shaft of the glasses must be tightly matched to stop at any time, so it feels more laborious to flip, and the pressure on the face is greater. Both upward and downward flipping must be pushed by hand, which takes a long time and is not convenient to use. Utility Model Content

[0003] In summary, in order to overcome the deficiencies of the prior art, the utility model provides a pair of fast-flipping glasses.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pair of quick-flip glasses, comprising temples, a fixed frame and a flip frame, a hinge assembly is arranged between the fixed frame and the flip frame, the hinge assembly comprises a hinge seat, a hinge, a spring and a marble, the hinge seat is provided with a hinge cavity for the hinge to be inserted and rotated, the hinge seat is provided with mounting holes for the hinge shaft to be inserted on both sides corresponding to the hinge cavity, the hinge comprises a hinge head hinged to the hinge seat, the hinge head is provided with a hinge hole matched with the hinge shaft, the hinge is hinged to the hinge seat through a hinge shaft, the hinge seat is provided with an installation cavity for accommodating a spring at the other end of the hinge seat opposite to the hinge cavity, the installation cavity is communicated with the hinge cavity, the marble is arranged between the spring and the hinge head, and the outer periphery of the hinge head is provided with a first positioning groove and a second positioning groove matched with the marble.

[0005] By adopting the above technical scheme, the flip frame and the fixed frame are elastic due to the cooperation of the spring and the marble, and the rotation is labor-saving. At the same time, the first positioning groove and the second positioning groove are used to position the two states of the flip frame, including the flip frame and the fixed frame are parallel state (use state) and the flip frame is rotated 90 degrees and is perpendicular to the fixed frame (non-use state). The switching between the two states is done in one step, and the operation is simple.

[0006] The utility model is further configured as follows: a first limiting portion is provided on the other side of the first positioning groove relative to the second positioning groove. When the marble is stuck in the first positioning groove, the first limiting portion abuts against the outer wall of the lower end of the hinge seat.

[0007] By adopting the above technical solution, not only the first positioning groove and the marble are used for positioning, but also the first limiting portion abuts against the outer wall of the lower end of the hinge seat, and multiple points of force are applied, which makes the stability higher and limits the downward flipping angle of the flip frame.

[0008] The utility model is further configured that a second limiting portion is provided on the other side of the second positioning groove relative to the first positioning groove, and when the marble is stuck in the second positioning groove, the front end of the second limiting portion abuts against the inner wall of the hinge cavity.

[0009] By adopting the above technical solution, the second positioning groove and the marble are used for positioning, and at the same time, the front end of the second limiting part abuts against the inner wall of the hinge cavity, and multiple points of force are applied to make the stability higher, thereby preventing the flipping angle of the flip frame from being too large. The abutment between the front end and the inner wall has a certain resilience, which prolongs the service life. The structure is simple, stable and reliable, and easy to use.

[0010] The utility model is further configured that: the first positioning groove and the second positioning groove are arranged between the first limiting portion and the second limiting portion, and the first limiting portion and the second limiting portion are arranged at an L-shaped angle.

[0011] By adopting the above technical solution, excessive rotation angle can be prevented, marbles can be prevented from falling off, and structural stability can be enhanced.

[0012] The utility model is further configured as follows: an external thread is provided at one end of the hinge shaft, an internal thread matching the external thread is provided at a mounting hole corresponding to one side of the external thread, a nut is provided at the other end of the hinge shaft, a straight slot or a cross slot is provided on the nut, and a mounting recess matching the nut is provided on one side of the hinge seat corresponding to the nut.

[0013] By adopting the above technical solution, disassembly and assembly are convenient, thread connection is adopted, and stability is high.

[0014] The utility model is further configured that: the hinge seat is installed in the middle of the fixed frame, and the hinged member is installed in the middle of the flip frame.

[0015] By adopting the above technical solution, the structure is simple, the single group is set up, and the cost is low.

[0016] The utility model is further configured as follows: the hinge assembly is divided into two groups, the hinge seats are respectively installed at the middle of the upper end of the frame of the fixed frame, and the hinged parts are respectively installed at the middle of the upper end of the frame of the flip frame.

[0017] By adopting the above technical solution, two groups are set up with high stability. They are set in the middle of the upper end of the frame, with moderate force arms, more balanced force and less effort.

[0018] The utility model is further configured as follows: the hinge assembly is divided into two groups, the hinge members are respectively mounted on both sides of the frame of the fixed frame, and the hinge seats are respectively mounted on both sides of the frame of the flip frame.

[0019] By adopting the above technical solution, the lever arm is shorter, and a certain amount of force is required on both sides, but the stability is high and the flip frame will not rotate easily.

[0020] The specific implementation of the utility model is described below in conjunction with the drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
