Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to telescopic temples of a metal frame. Background Art

[0002] The temples are one of the important components of glasses, and are mainly used to wear glasses on the ears. At present, temples are divided into metal products and plastic products. Metal temples have the advantages of high structural strength and long service life, while plastic temples have the advantages of light weight.

[0003] At present, the temples of some glasses can be extended and retracted to adjust the length, but the adjustment method is to extend the temples by pulling the temples, that is, the temples hung on the ears and the temples connected to the frame are slidably connected. Although this method can adjust the length of the temples, this connection method is prone to failure of the sliding between the two temples after long-term use, and the problem of the temples hanging on the ears easily falling off is prone to occur. In view of this, we propose retractable temples for metal frames. Utility Model Content

[0008] Preferably, the hanging rod is curved and is made of titanium alloy.

[0009] Preferably, a guide groove is provided at the bottom of the cavity, a slider is fixed at the front end of the bottom of the extension section, and the slider is slidably connected to the guide groove.

[0010] Preferably, the plurality of adjustment holes are linearly distributed at equal intervals along the top of the connecting section.

[0011] Preferably, the bottom end of the connecting section is threadedly connected to a limit pin at the rear end, and the top end of the limit pin extends into the guide groove and is in a protruding shape.

[0013] Preferably, the adjusting rod and the movable plate are both made of aluminum alloy, and the adjusting rod and the movable plate are an integrally formed structure.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] By setting the glasses: the extension section is inserted into the cavity of the connecting section, and the adjustment rod inside the extension section is plugged into the corresponding adjustment hole. Under the action of the adjustment rod and the adjustment hole, it is convenient to adjust the extension length of the extension section and to ensure the stable connection between the extension section and the connecting section, thereby preventing the glasses from detaching during wearing and ensuring the normal use of the glasses.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This embodiment provides a technical solution:

[0024] See also Figure 1-Figure 4 The telescopic temples of the metal frame include two temples hinged to the frame 10 of the glasses 1; the temples include a connecting section 11 hinged to the frame 10, a cavity 111 is provided at the rear end of the connecting section 11, a plurality of adjustment holes 112 connected to the cavity 111 are provided at the top of the connecting section 11, and a hinge head 12 is fixed to the front end of the connecting section 11; an extension section 14 is slidably installed in the cavity 111, a notch 141 is provided at the front end of the extension section 14, two guide rods 18 for guiding are fixed in the notch 141, a movable plate 16 that can be lifted and lowered is slidably installed above the two guide rods 18, a spring 19 for pressing the movable plate 16 is also sleeved on the guide rod 18, an adjusting rod 17 is fixed at the top center of the movable plate 16, the adjusting rod 17 passes through the extension section 14 and is plugged into the corresponding adjustment hole 112; a hanging rod 15 is fixed to the rear end of the extension section 14.

[0025] In this embodiment, the hanging rod 15 is curved, and the hanging rod 15 is made of titanium alloy material. Titanium alloy material has the advantages of corrosion resistance and high structural strength, which can improve wearing comfort, and the curved shape meets the requirements of eyeglass ear hanging.

[0026] In this embodiment, a guide groove 113 is provided at the bottom of the cavity 111, a slider 142 is fixed at the front end of the bottom of the extension section 14, and the slider 142 is slidably connected to the guide groove 113. The slider 142 and the guide groove 113 play a guiding role in the sliding connection between the extension section 14 and the connecting section 11, which helps to ensure the smoothness of the sliding.

[0027] In this embodiment, a plurality of adjustment holes 112 are linearly and evenly spaced along the top of the connecting section 11. This design facilitates the adjustment rod 17 to cooperate with the adjustment holes 112 at different positions, so as to facilitate the extension section 14 to be extended to different lengths.

[0028] In this embodiment, the bottom end of the connecting section 11 is threadedly connected to the limit pin 13 at the rear end, and the top end of the limit pin 13 extends into the guide groove 113 and is convex. The setting of the limit pin 13 has a limiting effect on the slider 142, which can prevent the extension section 14 from leaving the cavity 111.

[0029] In this embodiment, the connecting section 11 and the hinged joint 12 are integrally formed, and both the connecting section 11 and the hinged joint 12 are made of resin. The integrally formed connecting section 11 and the hinged joint 12 have better structural strength, ensure the connection strength of the connecting section 11 and the hinged joint 12, and increase the service life of the connecting section 11 and the hinged joint 12.

[0030] In this embodiment, the adjusting rod 17 and the movable plate 16 are both made of aluminum alloy, and the adjusting rod 17 and the movable plate 16 are an integrally formed structure. The integrally formed design makes the structural strength of the adjusting rod 17 and the movable plate 16 better, and the adjusting rod 17 and the movable plate 16 made of aluminum alloy have a high hardness, which ensures the service life of the adjusting rod 17 and the movable plate 16.

[0031] It should be added that the mirror frame 10 in this embodiment is made of nickel silver alloy, which has the advantages of being wear-resistant and corrosion-resistant, and is light in weight and low in price.

[0032] During specific use, the user first squeezes the adjusting rod 17 downward with a tool such as a small screwdriver, and the adjusting rod 17 drives the movable plate 16 to slide downward along the two guide rods 18, and the spring 19 is compressed by the movable plate 16 at the same time. Then the user holds the extension section 14 and pulls it to one side, and the extension section 14 slides along the cavity 111, and the slider 142 slides along the guide groove 113. When the adjusting rod 17 moves to the adjacent adjusting hole 112, under the elastic force provided by the spring 19, the movable plate 16 moves upward, and the adjusting rod 17 is stuck in the adjusting hole 112. At this time, the extension section 14 is fixed again, and the above steps are repeated to adjust the adjusting rod 17 between the multiple adjusting holes 112 until the extension section 14 is adjusted to a suitable length.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
