Description

Technical Field

[0001] The utility model belongs to the technical field of glasses, and particularly relates to a connecting structure of glasses temple legs. Background Art

[0002] The existing glasses temple legs are generally rotatably connected to one side of the spectacle frame through screws, so that the temple legs can rotate relative to the spectacle frame to open or close. Specifically, the structures disclosed in the Chinese utility model patent "A Pair of Glasses" with the application number CN202322695123.9 (the authorized announcement number is CN221039666U), the Chinese utility model patent "An integrally formed spectacle frame" with the application number CN202221118530.2 (the authorized announcement number is CN217606208U), etc.

[0003] When disassembling and assembling the temple legs, it is necessary to use a screwdriver to loosen or tighten the screws, which is rather inconvenient. And after using for a period of time, the screws may become loose or even fall off. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a connecting structure of glasses temple legs for the current situation of the prior art, so as to facilitate the disassembly and assembly of the temple legs.

[0005] The technical solution adopted by the utility model to solve the above technical problem is: a connecting structure of glasses temple legs, including a spectacle frame, and temple legs arranged on the left and right sides of the spectacle frame and having a connecting end and a free end, wherein a slot and a plug that can be inserted front and back are respectively provided at the connecting end of the temple leg and the position on the spectacle frame corresponding to the temple leg;

[0006] It is characterized in that:

[0007] A vertically extending convex shaft and a clamping groove are respectively provided on the inner wall surfaces of the plug and the slot. In the state where the plug is inserted into the slot, the convex shaft is clamped into the clamping groove, so that the temple leg is constrained to the spectacle frame in a manner that can rotate left and right around the central axis of the convex shaft and can be unfolded or folded relative to the spectacle frame;

[0008] At the same time, the slot wall or / and the plug or / and the convex shaft are arranged to be elastically deformable under an external force, so that the convex shaft is disengaged from the clamping groove, and then the plug is disengaged from the slot.

[0009] In this way, when the plug of the utility model is inserted into the slot, the convex shaft can be clamped into the clamping groove to assemble the temple leg and the spectacle frame together. At this time, the temple leg can rotate left and right around the central axis of the convex shaft and can be unfolded or folded relative to the spectacle frame, so that the temple leg can be used normally; because the slot wall or / and the plug or / and the convex shaft can be elastically deformed, when the temple leg needs to be removed, pulling the temple leg can disengage the plug from the slot, which is convenient for the disassembly and assembly of the temple leg.

[0010] Meanwhile, due to the cooperation between the convex shaft and the card slot, the present utility model can realize that the temple is rotatably constrained to the spectacle frame without additionally setting screws, which simplifies the structure and reduces the cost.

[0011] Preferably, the end of the convex shaft is inserted into the card slot, and the pin and the slot are in interference fit in the up and down directions. This can ensure that the pin is stably assembled in the slot. At the same time, it can avoid the temple shaking when rotating, so that the structure is stable when the temple is in the unfolded and folded states.

[0012] Preferably, the above-mentioned convex shaft is provided on the pin, and the above-mentioned card slots for the upper and lower ends of the corresponding convex shaft to be inserted are provided on the top surface and the bottom surface of the slot.

[0013] Furthermore, the pin is arranged to be elastically deformed in the up and down directions under an external force, so that the convex shaft disengages from the card slot, and then the pin disengages from the slot.

[0014] Furthermore, the slot is provided on the spectacle frame, the pin is provided at the connecting end of the temple, and the pin is integrally connected to the temple.

[0015] To enable the pin to elastically deform better, preferably, the pin has a foot piece extending forward from the end face of the connecting end of the temple. There are two foot pieces arranged at intervals, one above the other. The two foot pieces can approach each other under an external force. After the external force disappears, the two foot pieces reset. At the same time, a first protrusion is provided on the upper surface of the upper foot piece, and a second protrusion is provided on the lower surface of the lower foot piece. The first protrusion and the second protrusion together form the above-mentioned convex shaft.

[0016] Preferably, the convex shaft is located at the front end of the foot piece, and the convex shaft is integrally connected to the foot piece.

[0017] Preferably, the two foot pieces are located at the center of the end face of the connecting end of the temple. In this way, when the pin is inserted into the slot, the peripheral part of the end face of the connecting end can be attached to the end face where the slot opening is located.

[0018] Furthermore, the left side part of the slot on the left side of the spectacle frame is closed and the right side part is open; the right side part of the slot on the right side of the spectacle frame is closed and the left side part is open. The closed part of the slot can limit the temple when it is opened.

[0019] In the above-mentioned various solutions, preferably, the slot opening for the pin to be inserted is a flared opening with a gradually decreasing diameter along the insertion direction. The flared opening is convenient for the pin to align with the slot opening of the socket. And the flared opening with a gradually decreasing diameter is beneficial to the elastic deformation of the pin.

[0020] Compared with the prior art, the advantages of the present invention are as follows: the present invention inserts the pin into the slot, so that the convex shaft can be inserted into the slot to realize the assembly of the temple and the frame. At this time, the temple can rotate left and right around the central axis of the convex shaft and can be expanded or folded relative to the frame, so that the temple can be used normally; because the slot wall and / or the pin and / or the convex shaft of the slot can be elastically deformed, when the temple needs to be removed, the temple can be pulled to make the pin detach from the slot, which is convenient for disassembly and assembly of the temple.

[0021] At the same time, due to the cooperation between the convex shaft and the clamping groove, the utility model can realize that the temple can be rotatably constrained with the frame without the need for additional screws, thereby simplifying the structure and reducing the cost.

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] like Figures 1 to 6 As shown in FIG. 1 , a preferred embodiment of a glasses temple connection structure of the present invention is shown, and the connection structure includes a glasses frame 1 and a temple 2 .

[0030] The frame 1 is provided with two lenses, one on the left and one on the right. The left and right sides of the frame 1 are provided with slots 10 with slots facing backwards, and each slot is a trumpet mouth with a diameter gradually decreasing from the back to the front. At the same time, the left side of the slot 10 located on the left side of the frame 1 is closed and the right side is open; the right side of the slot 10 located on the right side of the frame 1 is closed and the left side is open.

[0031] Each temple 2 has a forward connecting end and a rearward free end, and the connecting end is provided with a pin 20 that can be inserted into the slot from the corresponding notch. At the same time, the pin 20 is provided with a convex shaft 21 extending vertically. On the top and bottom surfaces of the slot 10, there are clamping grooves 11 for the upper and lower ends of the corresponding convex shaft 21 to be inserted. In the state where the pin 20 is inserted into the slot 10, the pin 20 and the slot 10 are in interference fit in the vertical direction, and the convex shaft 21 is clamped into the clamping groove 11, so that the temple 2 is constrained to the frame 1 in a manner that can rotate left and right around the central axis of the convex shaft 21 and can be unfolded or folded relative to the frame 1. And the pin 20 is arranged to be elastically deformed in the vertical direction under an external force so that the convex shaft 21 disengages from the clamping groove 11, and then the pin 20 disengages from the slot 10.

[0032] Specifically, as Figure 4 , 6 shown, the pin 20 is integrally connected to the connecting end of the temple 2. The pin 20 has a foot piece 200 extending forward from the end face of the connecting end of the temple 2. There are two foot pieces 200, which are arranged at intervals, one above the other, in the center of the end face of the connecting end of the temple 2. The two foot pieces 200 can approach each other under an external force. After the external force disappears, the two foot pieces 200 reset. At the same time, the upper surface of the upper foot piece 200 is provided with a first protrusion 201, and the lower surface of the lower foot piece 200 is provided with a second protrusion 202. The first protrusion 201 and the second protrusion 202 together form the above-mentioned convex shaft 21. The first protrusion 201 and the second protrusion 202 are located at the front ends of their respective corresponding foot pieces 200 and are integrally connected to their respective corresponding foot pieces 200.

[0033] When installing the temple 2, insert the pin 20 into the slot 10 from the notch. At this time, the two foot pieces 200 approach each other until the convex shaft on the foot piece 200 is clamped into the corresponding clamping groove 11 in the slot 10, and then the two foot pieces 200 move away from each other and reset, so that the convex shaft 21 can be stably clamped in the clamping groove 11, thereby realizing the assembly of the temple 2 and the frame 1. At this time, the temple 2 can rotate left and right around the central axis of the convex shaft 21 and can be unfolded or folded relative to the frame 1. During the unfolding and folding process, the temple 2 does not shake and has a certain elastic effect.

[0034] When it is necessary to remove the temple 2, pull the temple 2 backward to make the pin 20 disengage from the slot 10, which is convenient for the disassembly and assembly of the temple 2.

[0035] In the description and claims of the present utility model, terms indicating directions, such as "front", "rear", "upper", "lower", "left", "right", etc., are used to describe various exemplary structural parts and elements of the present utility model. However, the use of these terms here is only for the purpose of convenient explanation and is determined based on the exemplary orientations shown in the drawings. Since the embodiments disclosed by the present utility model can be arranged in different directions, these terms indicating directions should be regarded as illustrative rather than restrictive. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.
