[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] A type of non-slip eyeglass frame, such as Figures 1 to 5 As shown, the device includes an eyeglass frame 100, with connecting arms 120 fixed to both sides of the eyeglass frame 100. A pair of lenses 110 are fitted inside the eyeglass frame 100, and a temple assembly 130 is rotatably connected to the end of the connecting arm 120.

[0024] The temple assembly 130 includes an inner rod 131 rotatably connected to the connecting arm 120. An outer frame strip 132 is movably sleeved on the outer wall of the inner rod 131. A storage groove 135 is provided on the inner side of the outer frame strip 132 near its end. An elastic strip 133 is installed in the storage groove 135. A disc 134 is fixed at one end of the elastic strip 133 near the connecting arm 120. A locking bolt 137 extending into the inner rod 131 is rotatably provided at the bottom end of the outer frame strip 132. Multiple sets of blind holes 136 are provided at the contact position between the bottom end of the inner rod 131 and the locking bolt 137.

[0025] A base shaft 1351 is fixed inside the storage slot 135 and is rotatably connected to the end of the elastic strip 133. A torsion spring 1352 extending into the elastic strip 133 is provided on the outer wall of the base shaft 1351.

[0026] Before wearing the glasses, the glasses can be adjusted according to the wearer's head size. An external force can be applied to the locking bolt 137 to make its end protrude from the blind hole 136. At this time, the lock between the inner rod 131 and the outer frame strip 132 is released. An external force can be applied to the outer frame strip 132 away from the eyeglass frame 100 until the total length of the outer frame strip 132 and the inner rod 131 meets the wearer's requirements. Finally, the locking bolt 137 is rotated to lock the inner rod 131 and the outer frame strip 132.

[0027] After wearing the glasses, apply an external force to the two sets of outer frame strips 132 away from the head to create a certain space between them and the head. At this time, rotate the elastic strip 133 around the base axis 1351 to the back of the head. Then remove the external force applied to the elastic strip 133. The torsion spring 1352 will generate a reverse torque, causing the elastic strip 133 to rotate in the opposite direction around the base axis 1351, so that the disc 134 contacts the back of the wearer's head, thereby enhancing the grip between the glasses frame 100 and the wearer's head. This allows the glasses frame 100 to be stably placed on the wearer's face, achieving a better anti-slip purpose.

[0028] Please refer to this carefully. Figure 2 The end face of the disc 134 that contacts the head is provided with a rubber pad.

[0029] Rubber pads are used to increase elasticity in contact with the head, ensuring greater comfort for the wearer.

[0030] Please refer to this carefully. Figure 3 and Figure 4 A rubber strip is fixed inside the storage slot 135, and a rubber groove is opened on the curved outer wall of the disc 134 at the position corresponding to the rubber strip.

[0031] Utilizing the deformable properties of the rubber strip, when the disc 134 enters the storage groove 135, the rubber strip can enter the rubber groove, so that the disc 134 can play a fixed and constrained role.

[0032] Please refer to this carefully. Figure 5 The upper inner wall of the outer frame strip 132 is provided with a spring retainer 139 extending into the inner rod strip 131. Multiple sets of grooves 138 are provided at the contact position between the top of the inner rod strip 131 and the spring retainer 139. The multiple sets of grooves 138 correspond one-to-one with the storage slots 135.

[0033] When the outer frame strip 132 is pulled to move along the outer wall of the inner rod strip 131, the groove 138 squeezes the spring retainer ball inward and moves along the top outer wall of the inner rod strip 131 until it enters another set of grooves 138. At this time, a locking effect is produced, which reminds the locking bolt 137 that it is aligned with the blind hole 136, making it easier to lock the outer frame strip 132 and the inner rod strip 131.

[0034] Please refer to this carefully. Figure 4 and Figure 5 The locking bolt 137 is located at one end of the inner rod 131 near the connecting arm 120, and the outer frame 132 has a matching threaded hole at the contact position with the locking bolt 137.

[0035] The threaded hole is used to lock the locking bolt 137, thereby stably controlling the total length of the inner rod 131 and the outer frame 132.

[0036] Before wearing the glasses, the glasses can be adjusted according to the wearer's head size. An external force can be applied to the locking bolt 137 to make its end protrude from the blind hole 136. At this time, the lock between the inner rod 131 and the outer frame strip 132 is released. An external force can be applied to the outer frame strip 132 away from the eyeglass frame 100 until the total length of the outer frame strip 132 and the inner rod 131 meets the wearer's requirements. Finally, the locking bolt 137 is rotated to lock the inner rod 131 and the outer frame strip 132.

[0037] After wearing the glasses, an external force is applied to the two sets of outer frame strips 132 away from the head, creating a certain space between them and the head. At this time, the elastic strip 133 is rotated around the base axis 1351 to the back of the head. Then, the external force applied to the elastic strip 133 is removed. At this time, the torsion spring 1352 will generate a reverse torque, causing the elastic strip 133 to rotate in the opposite direction around the base axis 1351, so that the disc 134 contacts the back of the wearer's head, thereby enhancing the grip between the glasses frame 100 and the wearer's head. This allows the glasses frame 100 to be stably placed on the wearer's face, achieving a better anti-slip purpose. The parts not mentioned in this device are the same as or can be implemented using existing technology.
