Description

Technical Field

[0001] The utility model relates to the technical field of ear studs, in particular to an ear stud locking mechanism. Background Art

[0002] Ear studs are a kind of ornaments worn on the ears. They are smaller than earrings and shaped like nails. They need to be passed through the ear holes to be worn. The shapes of ear studs are ever-changing, but the following characteristics cannot be changed. The front of the earlobe is the ear stud shape, and the back of the earlobe is the back of the ear (also called ear plug).

[0003] When wearing earrings, the earring needle passes through the ear hole, and an earring holder (lock) needs to be used to lock the earring needle to prevent the earring from falling off the ear. Traditional earring needle locking methods are as follows: 1. Use a small plastic tube to cover the earring needle, but the plastic tube is easy to detach or harden and cannot be removed; 2. Use screws to lock, but the screws will loosen and detach after long-term wearing; 3. Roll up a piece of round wire at the end of the earring needle for positioning, but it is easy to damage the ear with the shaking of wearing; 4. Hold the earring needle with a metal ear buckle, but the firmness will decrease after repeated wearing; 5. Lock with silicone earplugs, but it is easy to fall off; 6. Lock with metal silicone earplugs, which is prone to tilting and falling off; 7. Use curled metal sheets on both sides to clamp and lock the earring needle passing through the middle, but there is a problem of poor locking firmness, and it is inconvenient to break the curled part when wearing.

[0004] Therefore, how to provide an earring locking mechanism to improve the firmness and convenience of wearing the earrings has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an earring locking mechanism to improve the firmness and convenience of wearing the earring.

[0006] The utility model is implemented as follows: an earring locking mechanism, comprising:

[0007] An earring needle, with a plurality of annular grooves arranged side by side at the end, and the annular grooves are spaced apart by a preset distance;

[0008] A spring sheet, with a first through hole in the middle and elastic bending parts symmetrically bent upward on both sides;

[0009] A locking piece has a second through hole in the middle, and wrapping parts for wrapping a spring piece are respectively arranged at the front and rear edges of the second through hole; limiting grooves are respectively arranged at the front and rear edges on the left and right sides of the second through hole; limiting parts are respectively arranged at the front ends of the left and right sides and extend forward; a third through hole is respectively arranged between the limiting groove and the limiting part on the left side, and a fourth through hole is respectively arranged between the limiting groove and the limiting part on the right side; the second through hole, the third through hole and the fourth through hole are on the same axis, and a first distance between the third through hole and the left edge is not equal to a second distance between the fourth through hole and the right edge;

[0010] The locking piece is bent to wrap the spring piece so that the first through hole is aligned with the second through hole, and both sides overlap at the top of the spring piece, and the limiting part on the right side is bent based on the limiting groove on the left side, and the limiting part on the left side is bent based on the limiting groove on the right side;

[0011] The stud pin sequentially passes through the second through hole, the first through hole, the third through hole and the fourth through hole, and limits the spring piece and the locking piece through the annular groove.

[0012] Further, the spring piece is a stainless steel spring piece.

[0013] Further, the first through hole, the second through hole, the third through hole and the fourth through hole have the same diameter.

[0014] Further, the diameter of the first through hole matches the diameter of the stud pin.

[0015] Further, the difference between the first distance and the second distance is less than the diameter of the second through hole.

[0016] Further, the turning part of the limiting groove is arc-shaped.

[0017] The advantages of the present utility model are as follows:

[0018] By providing an earring stud, a spring piece and a locking piece, a plurality of annular grooves are arranged side by side at the end of the earring stud. A first through hole is provided in the middle of the spring piece. The locking piece is provided with a second through hole, a third through hole, a fourth through hole, a covering portion, a limiting groove and a limiting portion. The locking piece is bent to wrap the spring piece so that the first through hole is aligned with the second through hole, and both sides overlap at the top of the spring piece. Moreover, the limiting portion on the right side is bent based on the limiting groove on the left side, and the limiting portion on the left side is bent based on the limiting groove on the right side, and there is a dislocation between the third through hole and the fourth through hole. When wearing, by squeezing the locking piece on both sides to further squeeze the spring piece, the third through hole and the fourth through hole are coaxially aligned. Then, the earring stud is passed through the second through hole, the first through hole, the third through hole and the fourth through hole in sequence and falls into the two annular grooves respectively. Then, the applied pressure is released to reset the spring piece. The third through hole and the fourth through hole are misaligned under the elastic force of the spring piece, locking the spring piece and the locking piece in the annular groove. That is, through the spring piece and the misaligned third through hole and fourth through hole, the locking piece is locked in the annular groove, preventing it from loosening from the earring stud. Moreover, wearing or disassembling only requires squeezing the locking piece on both sides to squeeze the spring piece, which is very convenient, ultimately greatly improving the firmness and convenience of wearing the earring.

The third through hole 35 and the fourth through hole 36 are dislocated to a certain extent under the elastic force of the spring sheet 2, so that the spring sheet 2 and the locking sheet 3 are locked in the annular groove 11.

[0044] Disassembly:

[0045] By squeezing the locking sheet 3 and the spring sheet 2 from both sides, the misaligned third through hole 35 is made coaxial with the fourth through hole 36 , and then the earring needle 1 passes through the second through hole 31 , the first through hole 21 , the third through hole 35 and the fourth through hole 36 in sequence.

[0046] In summary, the advantages of the present invention are:

The locking piece is bent to wrap the spring piece so that the first through hole is aligned with the second through hole, and both sides overlap at the top of the spring piece. Moreover, the limiting portion on the right side is bent based on the limiting groove on the left side, and the limiting portion on the left side is bent based on the limiting groove on the right side, and there is a dislocation between the third through hole and the fourth through hole. When wearing, by squeezing the locking piece on both sides to squeeze the spring piece, the third through hole and the fourth through hole are coaxially aligned. Then, the earring pin is passed through the second through hole, the first through hole, the third through hole, and the fourth through hole in sequence and falls into the two annular grooves respectively. Then, the applied pressure is released to reset the spring piece. The third through hole and the fourth through hole are misaligned under the elastic force of the spring piece, locking the spring piece and the locking piece in the annular groove. That is, through the spring piece and the misaligned third through hole and fourth through hole, the locking piece is locked in the annular groove, preventing it from loosening from the earring pin. Moreover, wearing or disassembling only requires squeezing the locking piece on both sides to squeeze the spring piece, which is very convenient, ultimately greatly improving the firmness and convenience of wearing the earring.
