Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses technology and relates to a slingshot hinge mechanism for eyeglasses. Background Technology

[0002] Eyeglasses are a tool used to correct vision. Wearing eyeglasses can improve the clarity of seeing things. Currently, eyeglasses are mainly assembled from frames and lenses. The frames are hinged between the eyeglasses frame and the temples.

[0003] Currently, the hinge mechanism connecting the eyeglass frame and temples is mainly a single, integral hinge base. This integral structure makes the processing and connection of the hinge base inconvenient. Therefore, we designed a slingshot hinge mechanism for eyeglasses to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a slingshot hinge mechanism for eyeglasses to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: It includes a connecting base for fixing to a lens frame, a temple hinged to the connecting base, a hinge seat between the connecting base and the temple, the hinge seat being detachably connected to the connecting base, the hinge seat and the temple being detachably hinged, and an elastic limiting structure preventing the temple and connecting base from detaching. This design allows for separate processing of the hinge seat, facilitating assembly of the temple and connecting base via the hinge seat, thus simplifying manufacturing.

[0006] In the aforementioned slingshot hinge mechanism for eyeglasses, the elastic limiting structure includes a spring plate mounted on a connecting seat, with the end of the temple abutting against the spring plate. The purpose of this arrangement is that when an external force is applied to the temple, causing it to rotate during hinged contact, the spring plate provides a portion of the driving force for the temple's rotation, resulting in a smooth transition of the hinged rotational force.

[0007] In the aforementioned slingshot hinge mechanism for eyeglasses, the elastic plate is formed by cutting a section on the connecting seat to prevent bending. The end of the temple is bent to form a hinge section, which abuts against the elastic plate. This design integrates the elastic plate and the connecting seat into a single, stable structure.

[0008] In the aforementioned slingshot hinge mechanism for eyeglasses, a latch is provided at the outer end of the hinge section of the temple. When the hinge section and the elastic piece are engaged, the elastic piece is located in the latch at the outer end of the hinge section. This design ensures that the latch of the hinge section of the temple and the elastic piece are properly engaged, effectively preventing the elastic piece from shifting due to elastic contact, resulting in good structural stability.

[0009] In the aforementioned slingshot hinge mechanism for eyeglasses, the hinge seat has a symmetrically bent hinge portion, and the connecting seat has a locking position. The hinge portion of the hinge seat and the locking position of the connecting seat are assembled opposite each other. This design effectively prevents relative displacement between the hinge seat and the connecting seat during use, resulting in a more stable structural assembly.

[0010] In the aforementioned slingshot hinge mechanism for eyeglasses, the hinge seat has an open-shaped hinge hook on its hinge portion, and hinge lugs are provided on both sides of the hinge section on the temple. The hinge lugs and the hinge hooks of the hinge seat are assembled opposite each other. The purpose of this arrangement is to make the hinge lugs open, facilitating detachable assembly with the temple.

[0011] In the aforementioned slingshot hinge mechanism for eyeglasses, the cross-section of the hinge lug is rectangular.

[0012] Compared with the prior art, the advantages of the slingshot hinge mechanism for eyeglasses of this utility model are: the hinge seat of the slingshot hinge mechanism is processed separately, which makes it convenient for the temples and connecting seats to be assembled through the hinge seat, and the processing is convenient.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] Example 1

[0020] like Figure 1-4As shown, the present invention discloses a slingshot hinge mechanism for eyeglasses, including a connecting seat 1 for fixing to the eyeglass frame, an eyeglass temple 2 hinged to the connecting seat 1, a hinge seat 3 provided between the connecting seat 1 and the eyeglass temple 2, the hinge seat 3 being detachably connected to the connecting seat 1, the hinge seat 3 and the eyeglass temple 2 being detachably hinged, and an elastic limiting structure provided between the eyeglass temple 2 and the connecting seat 1 to prevent the eyeglass temple 2 from detaching from the connecting seat 1.

[0021] Specifically, the hinge seat 3 is machined in two parts, which makes it easy to assemble the temple 2 and the connecting seat 1 through the hinge seat 3, and the machining is convenient.

[0022] The elastic limiting structure includes a spring sheet 4 disposed on the connecting seat 1, and the end of the eyeglass temple 2 abuts against the spring sheet 4.

[0023] Specifically, when an external force is applied to the temple 2 and the temple 2 rotates at the hinge, the elastic plate 4 provides part of the driving force for the rotation of the temple 2, and the transition of the hinge rotation force is smooth.

[0024] The elastic piece 4 is formed by cutting on the connecting seat 1 to prevent bending. The end of the temple 2 is bent to form the hinge section 5. The hinge section 5 and the elastic piece 4 abut against each other.

[0025] Specifically, the elastic plate 4 and the connecting seat 1 are connected as a single structure, which is relatively stable.

[0026] The outer end of the hinge section 5 of the eyeglass temple 2 is provided with a latch 6. When the hinge section 5 and the elastic piece 4 abut against each other, the elastic piece 4 is located in the latch 6 at the outer end of the hinge section 5.

[0027] Specifically, the latch 6 of the hinge section 5 of the temple 2 and the elastic piece 4 cooperate with each other to effectively prevent the elastic piece 4 from shifting due to elasticity, resulting in good structural stability.

[0028] Example 2

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention relates to a slingshot hinge mechanism for eyeglasses. The hinge seat 3 is provided with a hinge part 7 formed by symmetrical bending, and the connecting seat 1 is provided with a locking position 8. The hinge part 7 of the hinge seat 3 and the locking position 8 of the connecting seat 1 are assembled opposite to each other.

[0030] Specifically, it can effectively prevent relative displacement between the hinge seat 3 and the connecting seat 1 during use, making the structural assembly more stable.

[0031] The hinge portion 7 of the hinge seat 3 is provided with an open-shaped hinge hook 9, and the hinge section 5 on the temple 2 is provided with hinge lugs 10 on both sides. The hinge lugs 10 and the hinge hooks 9 of the hinge seat 3 are assembled opposite each other.

[0032] Specifically, the hinged lug 10 is open to facilitate detachable assembly with the temple 2, and the cross-section of the hinged lug 10 is rectangular.

[0033] When assembling the hinge mechanism, firstly, the connecting seat 1 is fixedly welded to the eyeglass frame. Then, the hinge section 5 of the eyeglass temple 2 is inserted into the gap between the elastic piece 4 at the end of the connecting seat 1 and the connecting seat 1, so that the latch 6 at the end of the hinge section 5 is engaged with the elastic piece 4. Next, the hinge parts 7 on both sides of the top of the hinge seat 3 are passed through the latches 9 on both sides of the connecting seat 1, and the hinge hook 8 at the top of the hinge part 7 is assembled with the hinge lugs 10 opened on both sides of the hinge part 7, thus completing the assembly connection between the eyeglass temple 2 and the eyeglass frame.
