[0022] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] As shown in the figure, a pair of glasses with a weighted foot cover 3 includes a frame 1, a temple 2 and a foot cover 3, the temple 2 being hinged to the frame 1, the foot cover 3 having an insertion cavity 31, the free end of the temple 2 being inserted into the insertion cavity 31, the outer surface of the foot cover 3 being provided with a sliding groove 32 extending along the length direction of the temple 2 and communicating with the insertion cavity 31, the sliding groove 32 being provided with a sliding pile 4 which is interference fit with the side wall of the sliding groove 32, the sliding pile 4 being located in the portion of the sliding groove 32 and being provided with an insertion hole 41 matching the temple 2, the temple 2 being inserted into the sliding groove 32 and passing through the insertion hole 41, and the portion of the sliding pile 4 which passes out of the sliding groove 32 being connected with a counterweight 5.

[0024] In the above structure, moving the counterweight 5 can drive the sliding pile 4 to slide in the sliding groove 32 along the length direction of the foot wire 2. During the sliding process of the sliding pile 4, the foot wire 2 remains in the insertion hole 41 and a limit is imposed on the sliding pile 4, so that the sliding pile 4 remains in the sliding groove 32, and the counterweight 5 remains on the foot cover 3. The position of the counterweight 5 on the foot cover 3 is adjusted by sliding the sliding pile 4, and the interference fit between the sliding pile 4 and the inner wall of the sliding groove 32 is used to ensure that the counterweight 5 can be kept in the adjusted position. In this way, the center of gravity of the glasses as a whole is adjusted by the counterweight 5, so that the center of gravity of the glasses tends to be balanced, thereby ensuring the stability and comfort of the glasses when worn, and the position adjustment of the counterweight 5 will not change the overall length of the glasses and other specifications of the glasses, and will not affect the normal wearing of the glasses.

[0025] In addition, the structure of the counterweight block 5 connected to the sliding pile 4: the cross-section of the sliding pile 4 is T-shaped, and a connecting groove 51 that matches the large end of the sliding pile 4 is provided on the outer end surface of the counterweight block 5, and a connecting hole 52 that matches the small end of the sliding pile 4 is provided on the bottom of the connecting groove 51. A first expansion protrusion 53 with a first guide inclined surface 531 is formed on the bottom of the connecting groove 51, and a second expansion protrusion with a second guide inclined surface 421 is formed on the inner end surface of the large end of the sliding pile 4 42, the small end of the sliding pile 4 passes through the connecting hole 52 so that the large end of the sliding pile 4 is placed in the connecting groove 51, and when the counterweight block 5 is rotated until the first tightening protrusion 53 overlaps and abuts the second tightening protrusion 42, the inner end surface of the counterweight block 5 is tightly pressed against the outer surface of the foot cover 3. Through the above structure, the sliding pile 4 is limited by the foot wire 2 passing through the interlaced hole 41 and will not rotate. The counterweight block 5 can rotate on the sliding pile 4 by passing the sliding pile 4 through the connecting hole 52. During the rotation of the counterweight block 5 on the sliding pile 4 The counterweight 5 drives the first tightening protrusion 53 to rotate along the sliding pile 4. When the first tightening protrusion 53 rotates to the point where the first guide slope 531 contacts the second guide slope 421, the first tightening protrusion 53 gradually squeezes into the inner side of the second tightening protrusion 42 and overlaps with the second tightening protrusion 42 under the cooperation of the first guide slope 531 and the second guide slope 421. The inward movement of the first tightening protrusion 53 drives the counterweight 5 to slide inward on the sliding pile 4 and press against the outer side of the foot cover 3, thereby generating a tight contact with the foot cover 3. The friction force of the counterweight 5 limits the sliding of the sliding pile 4 in the sliding groove 32, so that the sliding pile 4 and the counterweight 5 are more stably maintained in the adjusted position, so that the counterweight 5 can more stably balance the center of gravity of the glasses. When the position of the counterweight 5 needs to be adjusted, the counterweight 5 is rotated so that the first tightening protrusion 53 and the second tightening protrusion 42 are staggered with each other, so that the counterweight 5 can be moved away from the position close to the foot cover 3, and the sliding pile 4 can be driven to slide in the sliding groove 32 by the counterweight 5.

[0026] In addition, the counterweight 5 and the sliding pile 4 are made of tungsten steel. Based on the high density and high strength characteristics of tungsten steel, the mass of the counterweight 5 and the sliding pile 4 under the same volume is increased, which can better play the role of adjusting the center of gravity balance of the glasses and ensure the durability of the counterweight 5 and the sliding pile 4.

[0027] In addition, a plurality of limiting grooves 33 are formed on the inner wall of the end of the insertion cavity 31, and a plurality of limiting protrusions 21 that match the limiting grooves 33 and are inserted into the limiting grooves 33 are formed on the foot wire 2. The cooperation between the limiting protrusions 21 and the limiting grooves 33 strengthens the stability of the connection between the foot wire 2 and the foot cover 3 after the foot wire 2 is inserted into the insertion cavity 31, thereby ensuring the stability of the sliding pile 4 when sliding along the foot wire 2 in the sliding groove 32.

[0028] In addition, a number of anti-slip protrusions 54 are formed on the inner end face of the counterweight block 5. The anti-slip protrusions 54 are tightly pressed against the outer face of the foot cover 3 when the counterweight block 5 is in contact with the foot cover 3, thereby increasing the friction between the counterweight block 5 and the foot cover 3, thereby making the counterweight block 5 and the sliding pile 4 more stably maintain the position after adjustment.

[0029] In addition, a screw cap 6 is provided on the counterweight block 5, which can make it easier to rotate the counterweight block 5 to limit the positions of the counterweight block 5 and the sliding pile 4, and the screw cap 6 covers the port of the connecting groove 51 to prevent debris from entering the connecting groove 51 and interfering with the rotation between the counterweight block 5 and the sliding pile 4.

[0030] In addition, a number of snap-fit ​​protrusions 61 are formed on the inner wall of the screw cap 6, and a number of snap-fit ​​grooves 55 matching the snap-fit ​​protrusions 61 are opened on the side surfaces of the counterweight block 5. The snap-fit ​​protrusions 61 are inserted into the snap-fit ​​grooves 55 to realize the connection between the screw cap 6 and the counterweight block 5. The above-mentioned connection method between the screw cap 6 and the counterweight block 5 facilitates the disassembly and assembly of the screw cap 6, and also ensures that the screw cap 6 can stably drive the counterweight block 5 to rotate through the cooperation between the snap-fit ​​protrusions 61 and the snap-fit ​​grooves 55.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
