Description

Technical Field

[0001] The utility model relates to the field of glasses, in particular to a temple of glasses. Background Art

[0002] Glasses are held on the wearer's ears by two temples. The end of the temple far from the frame is hook-shaped. When the glasses are worn, the hook-shaped end of the temple will rest on the back of the wearer's ear, thus achieving the effect of fixing the glasses.

[0003] However, there are differences in the shapes of everyone's ears, which results in the hook part of the temple being unable to effectively fit and rest on the ears of some myopic people, thereby reducing the stability of the glasses when worn and making the glasses easy to fall off, affecting the wearing experience of the glasses. Summary of the Utility Model

[0004] This application provides a temple of glasses, which enables the second leg body to better rest on the ear of the glasses wearer when the glasses are worn by rotating the second leg body.

[0005] The temple of glasses provided by this application adopts the following technical solutions:

[0006] A temple of glasses includes a first leg body and a second leg body. One end of the first leg body far from the second leg body is connected to the frame. An assembly groove is formed on the surface of the first leg body facing the second leg body along the length direction of the first leg body. The end of the second leg body is hinged in the assembly groove. A first arc-shaped end face is provided at the end of the second leg body located in the assembly groove. A plurality of card slots are formed on the first arc-shaped end face. The plurality of card slots are circumferentially arranged on the first arc-shaped end face with the hinge axis of the second leg body as the center. A sliding groove is formed on the surface of the assembly groove facing the second leg body. A clamping block that is in clamping fit with the card slot is slidably connected in the sliding groove. A spring is further provided in the sliding groove. The spring is used to drive the clamping block to move towards the second leg body side so that when the second leg body rotates, the clamping block intermittently snaps into the adjacent card slot.

[0007] By adopting the above technical solution, the spring will push the locking block to be stuck in one of the card slots in the initial state. When the second leg rotates, the side wall of the card slot that is engaged with the locking block will first push the locking block to move into the sliding groove and disengage from the card slot. When the locking block moves into the sliding groove, the spring will be compressed under force. Then, as the second leg continues to rotate, another new card slot will move onto the movement path of the locking block. At this time, the spring will rebound to drive the locking block to move so that the locking block is stuck into the new card slot. Therefore, when the second leg rotates, the locking block will intermittently be stuck into different card slots. When the locking block is stuck into the new card slot, the angle between the second leg and the first leg will change. At the same time, the cooperation between the locking block and the card slot can prevent the rotation of the second leg. Through the cooperation of the locking block and the card slot, multi-stage adjustment of the rotation angle of the temple can be achieved, and the second leg can be limited after the second leg rotates. Therefore, before wearing the glasses, the wearer can rotate the second leg according to the contour of their ear so that the second leg rotates to a suitable position, so that when wearing the glasses, the second leg can better rest on the wearer's ear and fit the wearer's ear, improving the stability of the glasses when worn.

[0008] Preferably, a receiving hole is formed on the surface of the sliding groove away from the second leg. The spring is arranged in the receiving hole. One end of the spring abuts against the bottom wall of the receiving hole, and the other end of the spring abuts against the locking block.

[0009] By adopting the above technical solution, the formation of the receiving hole restricts the deformation direction of the spring, so that the elastic force of the spring can be effectively converted into the driving force for the sliding of the slider, and the spring can stably press the locking block in the card slot.

[0010] Preferably, a limiting rod is provided on the locking block. The limiting rod extends into the receiving hole, and the spring is sleeved on the limiting rod.

[0011] By adopting the above technical solution, the stability of the connection between the spring and the locking block is improved, so that the force of the spring to rebound can fully act on the locking block. At the same time, it also cooperates with the receiving hole to limit the direction of the force deformation of the spring, ensuring the force conversion efficiency.

[0012] Preferably, a cover plate is further provided on the first leg. The cover plate seals the top opening of the assembly groove, and the cover plate is used to abut against the second leg to limit the upward rotation of the second leg.

[0013] By adopting the above technical solution, the cover plate is provided to block the movement path of the upward turning of the second leg, preventing the first leg from turning upward due to external force when wearing the glasses, because if the second leg turns upward, it will not be able to effectively rest on the wearer's ear.

[0014] Preferably, a second arc-shaped end face is provided at one end of the first leg body where it is connected to the second leg body. A first limit block is provided on the second leg body, and the first limit block is used to abut against the second arc-shaped end face to limit the upward rotation of the second leg body.

[0015] By adopting the above technical solution, the cooperation between the first limit block and the second arc-shaped end face can assist the cover plate to block the upward rotation of the second leg body.

[0016] Preferably, a second limit block is provided at one end of the second leg body away from the first leg body. An installation ring groove is provided between the second limit block, the first limit block, and the second leg body. A rubber sleeve is provided in the installation ring groove, and the rubber sleeve is sleeved on the second leg body.

[0017] By adopting the above technical solution, setting the rubber sleeve can protect the skin of the ear when the second leg body is placed on the wearer's ear, improving the comfort of wearing the glasses.

[0018] Preferably, the first leg body includes a connecting pipe connected to the spectacle frame and an adjusting rod slidably connected to one end of the connecting pipe. The assembly groove is provided at one end of the adjusting rod away from the connecting rod. A first threaded hole is provided on the connecting pipe, and a bolt is threadedly connected in the first threaded hole. A plurality of second threaded holes connected to the bolt are provided at one end of the adjusting rod located inside the connecting pipe, and the plurality of second threaded holes are arranged along the length direction of the adjusting rod.

[0019] By adopting the above technical solution, the length of the temple can be adjusted by screwing the bolt into different second threaded holes.

[0020] The technical effects of the present utility model are mainly reflected in the following aspects:

[0021] 1. In the present utility model, by rotating the second leg body, the second leg body can better rest on the ear of the glasses wearer when wearing the glasses, improving the stability of wearing the glasses;

[0022] 2. In the present utility model, the cooperation between the clamping block and the clamping groove is used to limit the rotation of the second leg body after the second leg body rotates and hooks the ear of the glasses wearer, so that the second leg body can play a stable role;

Specific embodiments

[0032] The following further describes the present application in detail with reference to the accompanying drawings to make the technical solutions of the present application easier to understand and master.

[0033] Refer to Figure 1 and Figure 7 , a pair of temple arms of this embodiment includes a temple body 1, and the temple body 1 includes a first leg body 2 connected to the spectacle frame. The first leg body 2 includes a connecting pipe 11 connected to the spectacle frame and an adjusting rod 12 slidably connected to one end inside the connecting pipe 11. A first threaded hole 13 is opened on the connecting pipe 11, the first threaded hole 13 communicates with the inner cavity of the connecting pipe 11, and a bolt 15 is threadedly connected in the first threaded hole 13. Two second threaded holes 14 connected to the bolt 15 are opened at one end of the adjusting rod 12 located inside the connecting pipe 11, and the two second threaded holes 14 are arranged along the length direction of the adjusting rod 12. By screwing the bolt 15 into different second threaded holes 14, the length of the temple arms can be adjusted.

[0034] Refer to Figures 1-4, a fitting groove 21 is formed in the end face of the adjusting rod 12 away from the connecting rod along the length direction of the adjusting rod 12. The temple body 1 further includes a second leg body 3 hinged at one end in the fitting groove 21. A first arc-shaped end face 41 is provided at the end of the second leg body 3 located in the fitting groove 21. A plurality of card slots 42 are formed in the first arc-shaped end face 41. The plurality of card slots 42 are circumferentially arranged on the first arc-shaped end face 41 with the hinge axis of the second leg body 3 as the center. A sliding groove 43 is formed in the surface of the fitting groove 21 facing the second leg body 3. A clamping block 44 that is in clamping fit with the card slot 42 is slidably connected in the sliding groove 43 along the length direction of the first leg body 2.

[0035] Referring to Figures 1-4 , a receiving hole 22 is formed in the surface of the sliding groove 43 away from the second leg body 3. A spring 45 is placed in the receiving hole 22. A limiting rod 5 is fixed on the surface of the clamping block 44 facing the spring 45. The limiting rod 5 extends into the receiving hole 22. The spring 45 is sleeved on the limiting rod 5. One end of the spring 45 abuts against the bottom wall of the receiving hole 22, and the other end of the spring 45 abuts against the clamping block 44. The spring 45 is always in a compressed state and always presses the clamping block 44 against the first arc-shaped end face 41.

[0036] Referring to Figure 1 , Figure 2 and Figure 5 , a cover plate 10 is fixed on the first leg body 2. The cover plate 10 seals the top opening of the fitting groove 21. The cover plate 10 is used to abut against the second leg body 3 to limit the upward rotation of the second leg body 3. A second arc-shaped end face 23 is formed at the end of the first leg body 2 connected to the second leg body 3. A first limiting block 6 is provided on the second leg body 3. The first limiting block 6 is used to abut against the second arc-shaped end face 23 to limit the upward rotation of the second leg body 3.

[0037] Referring to Figure 1 and Figure 6 , a second limiting block 7 is fixed on the end of the second leg body 3 away from the first leg body 2. A limiting fitting groove 21 is provided between the second limiting block 7 and the first limiting block 6. A rubber sleeve 9 is provided in the limiting fitting groove 21. The rubber sleeve 9 is sleeved on the second leg body 3.

[0038] Referring to Figures 1-6, in the initial state, the spring 45 will push the latch 44 to be stuck in one of the card slots 42. After the temple body 1 and the spectacle frame are combined into an integral pair of glasses, when pressing the end of the second leg body 3 away from the first leg body 2 to make the second leg body 3 rotate downward, the side wall of the card slot 42 that is engaged with the latch 44 will first push the latch 44 to move into the chute 43 and disengage from the card slot 42. When the latch 44 moves into the chute 43, the spring 45 will be compressed by the force. Then, as the second leg body 3 continues to rotate, another new card slot 42 will move onto the movement path of the latch 44. At this time, the spring 45 will rebound to drive the latch 44 to move so that the latch 44 is stuck in the new card slot 42. Therefore, when the second leg body 3 rotates, the latch 44 will be intermittently stuck into different card slots 42 under the push of the spring 45.

[0039] Therefore, when the second leg body 3 rotates, the latch 44 will be intermittently stuck into different card slots 42. When the latch 44 is stuck into the new card slot 42, the angle between the second leg body 3 and the first leg body 2 will change. At the same time, the cooperation between the latch 44 and the card slot 42 can prevent the rotation of the second leg body 3. Through the cooperation of the latch 44 and the card slot 42, multi-stage adjustment of the rotation angle of the temple can be achieved, and the second leg body 3 can be limited after rotation. The rotation angle gears of the second leg body 3 are 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, and 90 degrees.

[0040] Therefore, before wearing the glasses, the glasses wearer rotates the second leg body 3 according to their own needs and makes the latch 44 be stuck in the appropriate card slot 42. The latch 44 will limit and fix the rotated second leg body 3 through the cooperation with the card slot 42. After the second leg body 3 rotates, it can better rest on the wearer's ear and fit the wearer's ear, improving the stability of the glasses when worn.

[0041] Of course, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope protected by this application.
