Description

Technical Field

[0001] The present invention relates to the technical field of magnetic primary and secondary glasses, and in particular to a magnetic primary and secondary glasses with stable combination. Background Art

[0002] Magnetic combination glasses usually include a main frame and a sub-frame. The main frame is equipped with a first magnet on the left and right piles, and the sub-frame is equipped with a second magnet that is magnetically attracted to the first magnet on both sides. The sub-frame is fixed to the front side of the main frame by magnet attraction, and the corresponding lenses can filter light according to different usage scenarios. Existing magnetic glasses will set a groove with a downward opening on the middle beam of the sub-frame, and the middle beam of the sub-frame is hung on the middle beam of the main frame through the groove, and the sub-frame is limited and guided to assist the magnets of the two to align and attract; but when the sub-frame is hit upward, the middle beam and magnet of the sub-frame are easily separated from the main frame, causing the sub-frame to fall to the ground and be damaged. Therefore, designing a combination of stable magnetic main and sub-frames that can avoid magnet separation when hit has become a technical problem that needs to be solved urgently. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a combination of stable magnetic primary and secondary glasses.

[0005] After adopting the above structure, the connecting posts on both sides of the auxiliary mirror frame are fixed to the pile heads by magnet attraction, and the connecting posts extend above the pile heads to prevent the connecting posts from moving leftward, rightward, and downward and separating from the pile heads; by moving the flexible sleeve of the fixing piece, after the connecting post and the magnets of the pile heads are attracted, the flexible sleeve is simultaneously sleeved on the outside of the two by utilizing the gap with the pile heads, and the size of the gap is matched with the connecting post and the magnet, so that the connecting post is blocked from moving upward by the flexible sleeve, and a part of the fixing piece is seated on the flexible sleeve, and the tail end of the fixing piece is connected to the temples to help the connecting posts block the collision from the rear of the glasses, providing all-round protection and fixation, and preventing the auxiliary mirror frame from falling off and breaking after being hit; the connecting post is fixed above the pile head by magnet attraction, and the pile head and the connecting post are simultaneously wrapped by utilizing the gap of the flexible sleeve, so that the glasses are prevented from being separated due to collision, and the auxiliary mirror frame is prevented from falling to the ground and being damaged.

The size of the mounting groove matches that of the magnet. The magnet is fixed in the mounting groove, and flat attracting surfaces are provided on both the upper and lower sides of the magnet.

[0007] With the above structure, since the magnet is fixed in the mounting groove and the attracting surfaces correspond to the notch of the mounting groove, when the magnets on the pile head and the connecting column attract each other, no extra space will be occupied, the size of the required flexible sleeve can be reduced, and materials can be saved.

[0008] As a further improvement of the present utility model, a main lens bridge is provided in the middle of the main lens frame. The auxiliary lens frame is provided with an auxiliary lens bridge corresponding to the position of the main lens bridge. The auxiliary lens bridge is provided with a fixing hook that bypasses the rear side of the main lens bridge from top to bottom. The fixing hook is made of an elastic material.

[0009] With the above structure, the fixing hook made of an elastic material bypasses the rear side of the main lens bridge from top to bottom, and the auxiliary lens bridge is hooked on the main lens bridge, further preventing the auxiliary lens frame from separating from the main lens frame forward after being stressed.

[0010] As a further improvement of the present utility model, an arc surface is provided on the side of the connecting column facing the temple.

[0011] With the above structure, since an arc surface is provided on the side of the connecting column facing the temple, when the flexible sleeve is put on, the end of the connecting column is not easy to cut the flexible sleeve, and the arc surface can guide the flexible sleeve to expand to both sides, making it easier to put the flexible sleeve on the outside of the pile head and the connecting column.

[0019] The connecting columns 5 on both sides of the sub - frame 2 and the bifurcations 4 are fixed by magnetic attraction of the magnets 6, and the connecting columns 5 extend above the bifurcations 4 to prevent the connecting columns 5 from moving left, right, or downward and separating from the bifurcations 4. By moving the flexible sleeve 8 of the fixing member, after the magnets 6 on the connecting columns 5 and the bifurcations 4 are attracted, using the gap with the bifurcation 4, the flexible sleeve 8 is simultaneously sleeved outside both of them. Since the size of the gap matches that of the connecting column 5 and the magnet 6, the flexible sleeve 8 blocks the upward movement of the connecting column 5. As a part of the fixing member, the tail end 7 of the fixing member is connected to the temple 3, so as to block the collision from the rear of the glasses for the connecting column 5, providing all - round protection and fixation to prevent the sub - frame 2 from falling off the main frame 1 and being damaged after being collided; it realizes that the connecting column 5 is attracted by the magnet 6 and fixed above the bifurcation 4, and the gap of the flexible sleeve 8 wraps the bifurcation 4 and the connecting column 5 at the same time, preventing the two from separating due to the collision of the glasses and avoiding damage to the sub - frame 2 when it lands.

[0021] By fixing the magnet 6 in the installation groove 9 and the attraction surfaces corresponding to the notch of the installation groove 9, when the magnets 6 on the bifurcation 4 and the connecting column 5 are attracted, no extra space is occupied, the size of the required flexible sleeve 8 is reduced, and materials are saved.

[0022] A main bridge 10 is provided in the middle of the main frame 1. A sub - bridge 11 corresponding to the position of the main bridge 10 is provided on the sub - frame 2. A fixed hook 12 that bypasses the rear side of the main bridge 10 from top to bottom is provided on the sub - bridge 11, and the fixed hook 12 is made of elastic material.

[0023] The fixing hook 12 made of an elastic material bypasses the rear side of the main mirror beam 10 from top to bottom, and hooks the auxiliary mirror beam 11 on the main mirror beam 10, further preventing the auxiliary mirror frame 2 from separating from the main mirror frame 1 forward after being stressed.

[0024] An arc surface 13 is provided on one side of the connecting column 5 facing the temple 3.

[0025] Since an arc surface 13 is provided on one side of the connecting column 5 facing the temple 3, when the flexible sleeve 8 is put on, the end of the connecting column 5 is not easy to cut through the flexible sleeve 8, and the arc surface 13 can guide the flexible sleeve 8 to expand to both sides, making it easier for the flexible sleeve 8 to be put on the outside of the pile head 4 and the connecting column 5.
