Description

Technical Field

[0001] The utility model relates to the technical field of glasses, in particular to a pair of sports sunglasses. Background Technique

[0002] Sunglasses, also known as sunshades, are used for sunshading. When people are in the sun, they usually rely on adjusting the pupil size to adjust the light flux. When the light intensity exceeds the adjustment ability of the human eye, it will cause damage to the human eye. Therefore, in outdoor activity places, especially in summer, sunglasses are needed to block the sun. Sunglasses can effectively block ultraviolet rays and avoid the stimulation of strong light, so as to reduce the fatigue caused by eye adjustment or the damage caused by strong light stimulation.

[0003] At present, many sunglasses cannot meet the needs of consumers when in use. For example, when the wearer is cycling or exercising, there will be bumps, and the glasses will slide down along the nose, resulting in the wearer's line of sight being blocked and unable to achieve the purpose of blocking the sun. At the same time, the lenses of sports sunglasses are fixed on the frame, and the lenses cannot be removed. For sunglasses with aging or scratches, only the whole needs to be replaced. Therefore, a pair of sports sunglasses is proposed. Content of the Utility Model

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0022] The following will describe the embodiments according to the overall structure of the present utility model.

[0023] A sports sunglasses, as Figures 1 to 5 shown, includes a frame 100. An active frame 110 is provided on the front surface of the frame 100. A lens 130 is clamped between the active frame 110 and the frame 100. Two groups of positioning grooves 131 are opened at a position near the top of the front surface of the lens 130. A clamping block 112 is fixedly arranged at a corresponding position between the rear surface of the active frame 110 and the positioning groove 131. Base columns 101 are fixedly arranged at positions near the two side edges of the front surface of the frame 100. The two groups of base columns 101 extend into the active frame 110. A constraint groove 111 is opened at the contact position between the rear surface of the active frame 110 and the two groups of base columns 101. An eccentric piece 102 is rotatably arranged at the top of the frame 100 by a rubber rod. Temple pieces 140 are rotatably arranged at positions near the two side edges of the rear surface of the active frame 110. An arc piece 150 is rotatably arranged at a position near the end of the outer wall of the temple piece 140;

[0024] A travel groove 141 is opened on the outer wall of the temple piece 140. A slider 142 is movably arranged in the travel groove 141. A damping shaft 143 is fixedly arranged on the outer wall of the slider 142. The damping shaft 143 is rotatably arranged with the arc piece 150.

[0025] When wearing, push or pull the arc piece 150 to move according to the needs. At this time, the slider 142 will be driven to move in the travel groove 141 until it fits the wearer. Then, turn the arc piece 150 downward to make it contact the back of the wearer's ear. In this way, the stability of the sunglasses can be increased, and the situation of the sunglasses tilting forward can be better prevented, and it is better to use when the wearer is exercising;

[0026] When disassembling the lens 130, rotate the eccentric piece 102 to separate it from the top of the active frame 110. At this time, the active frame 110 can be pushed upward. The constraint groove 111 and the base column 101 cooperate to make the active frame 110 vertically upward. At this time, the clamping block 112 will be separated from the positioning groove 131 until the bottom end of the active frame 110 is higher than the top end of the lens 130. Then, the lens 130 can be taken out for replacement.

[0027] Please refer with emphasis to Figure 2 and body 3. A nose pad 120 is fixedly arranged at the middle position of the bottom end of the frame 100. A constraint groove is opened at the contact position between the outer wall of the nose pad 120 and the lens 130. The rear surface of the nose pad 120 is wrapped with a soft rubber layer.

[0028] The lens 130 is limited by the constraint groove and cooperates with the spectacle frame 100 and the movable spectacle frame 110 to complete the locking of the lens 130. At the same time, the soft rubber layer provides comfort for the wearer's nose.

[0029] Please refer particularly to Figure 1 and Figure 4 , the temple 140 is composed of an inner strip and an outer frame, and the inner strip and the outer frame are fastened by bolts.

[0030] So that the length of the temple 140 can be adjusted according to the needs of each person to meet the wearing requirements.

[0031] Please refer particularly to Figure 5 , the upper and lower ends of the slider 142 are provided with dovetail blocks extending into the travel groove 141, and the inner wall of the travel groove 141 is provided with dovetail grooves matching the dovetail blocks.

[0032] Please refer particularly to Figure 1 and Figure 4 , a rubber pad 151 is pasted on the curved inner wall of the arc-shaped piece 150.

[0033] The rubber pad 151 is used to increase the gripping force between the back of the ear and provide better comfort.

[0034] When wearing, push or pull the arc-shaped piece 150 to move according to the needs. At this time, the slider 142 will be driven to move in the travel groove 141 until it fits the wearer. Then, turn the arc-shaped piece 150 downward to make it contact the back of the wearer's ear. In this way, the stability of the sunglasses can be increased, the situation of the sunglasses tilting forward can be better prevented, and the wearer's movement can be better adapted;

[0035] When removing the lens 130, rotate the eccentric piece 102 to separate it from the top of the movable spectacle frame 110. At this time, the movable spectacle frame 110 can be pushed upward. The constraint groove 111 and the base post 101 cooperate to make the movable spectacle frame 110 vertical upward. At this time, the latch 112 will be separated from the positioning groove 131 until the bottom end of the movable spectacle frame 110 is higher than the top end of the lens 130. Then, the lens 130 can be taken out for replacement. The parts not involved in this device are the same as or can be implemented by the prior art.

[0036] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
