Description

Technical Field

[0001] This utility model relates to the field of earring technology, and in particular to an earring locking mechanism that facilitates alignment. Background Technology

[0002] As a common earring accessory, the secure fit and ease of wearing earrings are crucial, and the design of the locking mechanism directly affects the user experience. In the field of earring locking, existing technologies exist aimed at solving the problem of earring post fixation. For example, utility model patent CN223025547U discloses an earring locking mechanism comprising an earring post, a spring plate, and a locking plate. The earring post has multiple annular grooves at its end, the spring plate has a first through hole in its center, and the locking plate has a second, third, and fourth through hole, forming an overlapping structure by bending and wrapping around the spring plate. When wearing the earring, the post must pass through the second, first, third, and fourth through holes sequentially, using the annular grooves to limit the components, thereby achieving locking.

[0003] This locking mechanism enhances the locking stability through the elasticity of the spring plate and the misalignment of the through holes. After the spring plate and the locking plate are assembled, the third and fourth through holes are pre-misaligned. After the earring pin is inserted, the spring plate resets to achieve locking. This design avoids, to some extent, the problem of traditional earring holders easily falling off, such as hardening of the plastic sleeve, loose screws, or tilting of the silicone earplug.

[0004] However, in practical applications, it has been found that the above-mentioned earring locking mechanism has obvious technical defects: when the earring pin passes through the second, first, third, and fourth through holes in sequence, it is difficult to quickly and accurately align the earring pin with all the through holes during operation because multiple through holes need to be kept coaxially aligned after the locking plate is pressed. This is mainly because: 1. There are a large number of through holes, which are distributed on different components. When pressing the locking plate, the alignment of the through holes depends on the user's technique and force, which can easily lead to deviations.

[0005] 2. When the locking tab is unfolded, the distances between the third and fourth through holes and the edge are not equal (the first distance and the second distance are not equal), which causes the through holes to misalign after bending. Although this is beneficial for locking, it increases the difficulty of alignment, and the user needs to adjust repeatedly to successfully thread the needle.

[0006] This inconvenience in alignment not only reduces wearing efficiency but can also lead to bent earring posts or worn components due to repeated attempts, affecting the lifespan and security of the locking mechanism. Furthermore, this drawback is particularly pronounced for elderly users or those with limited hand dexterity, restricting the widespread adoption of this locking mechanism. Therefore, providing an earring locking mechanism that facilitates alignment, simplifies the insertion process, and improves wearing convenience and user experience while maintaining a secure lock has become a pressing technical challenge. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide an earring locking mechanism that is easy to align, thereby simplifying the process of inserting the earring needle and improving the convenience of wearing and user experience while maintaining a secure lock.

[0008] This utility model is implemented as follows: an earring locking mechanism for easy alignment, comprising: An earring post; A spring sheet with a first through hole in the middle and elastic bending parts symmetrically bent upwards on both sides; A locking plate has a second through hole in the middle, and a covering part for covering the spring plate is provided at the front and rear edges of the second through hole; a limiting groove is provided at the front and rear edges of the left and right sides of the second through hole; a limiting part is provided at the end of the left and right sides respectively; a third through hole is provided between the limiting groove and the limiting part on the left side, and a fourth through hole is provided between the limiting groove and the limiting part on the right side. A guide tube has an annular flange at its top end; the outer diameter of the guide tube matches the first through hole and passes through the first through hole; the annular flange is located between the spring plate and the locking plate and is used to limit the guide tube. The locking tab is bent to wrap around the spring sheet, so that the first through hole is aligned with the second through hole, and the two sides overlap each other at the top of the spring sheet. 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. The earring pin passes through the second through hole, the guide tube, the third through hole, and the fourth through hole in sequence.

[0009] Furthermore, the end of the earring pin is provided with several annular grooves arranged side by side, which limit the spring sheet and the locking plate.

[0010] Furthermore, each of the annular grooves is spaced apart by a predetermined distance.

[0011] Furthermore, the second through hole, the third through hole, and the fourth through hole are on the same axis.

[0012] Furthermore, the first distance between the third through hole and the left edge and the second distance between the fourth through hole and the right edge are equal.

[0013] Furthermore, the spring sheet is a stainless steel spring sheet.

[0014] Furthermore, the first through hole, the second through hole, the third through hole, and the fourth through hole have the same diameter.

[0015] Furthermore, the inner diameter of the guide tube matches the outer diameter of the earring needle.

[0016] Furthermore, the turning point of the limiting groove is arc-shaped.

[0017] The advantages of this utility model are: 1. By introducing a guide tube with an annular flange at the top, and placing it below the second through hole of the locking plate after passing through the first through hole of the spring plate, a pre-aligned rigid guide channel is constructed. This design simplifies the complex path that the earring needle originally needed to align with four scattered through holes in sequence, to simply aligning it with the second through hole on the locking plate. The needle automatically enters the guide tube, and the inner wall of the guide tube provides a stable and straight path, thus bypassing the misalignment obstacles of the third and fourth through holes in their natural state. This significantly reduces the difficulty of threading the needle and the dependence on operating techniques. While maintaining the secure locking function brought about by the bending structure of the locking plate and the misalignment of the through holes, it fundamentally improves the intuitiveness, speed, and success rate of wearing the earring, and optimizes the user experience.

[0018] 2. Through the coordinated design of the guide tube, the first through hole of the spring plate, and the second, third, and fourth through holes of the locking plate, the earring needle is precisely guided. The outer diameter of the guide tube matches the first through hole, and the annular flange provides a limit, ensuring that the earring needle does not require manual fine adjustment by the user when passing through, thereby reducing the difficulty of wearing. This structure is particularly suitable for the daily use of earrings, reducing discomfort or failure caused by misalignment and improving the user experience.

[0019] 3. The elastic bending parts on both sides of the spring sheet cooperate with the covering part, limiting groove and limiting part of the locking piece to form an elastic clamping mechanism; when the locking piece bends to wrap the spring sheet, the limiting part bends crosswise based on the limiting groove to generate continuous elastic force, so that the earring post can be firmly locked after passing through the through hole; this design prevents the earring from loosening or falling off due to movement, and is especially suitable for sports or daily activities, improving the safety of wearing.

[0020] 4. The earring post has several annular grooves at the end, allowing users to fine-tune the position according to the thickness of the earlobe. Different grooves can be selected for positioning. The annular grooves are spaced at preset distances to ensure the accuracy and consistency of the adjustment. This adjustable design allows the mechanism to adapt to the anatomical differences of different users, enhancing the product's versatility and personalized experience.

[0021] 5. The second, third, and fourth through holes are on the same axis, and the diameters of the first, second, third, and fourth through holes are the same, ensuring the smooth passage and alignment accuracy of the earring needle. This coaxial and equal-diameter design reduces friction and deviation between components, improves assembly efficiency, and reduces production complexity, which is beneficial for large-scale manufacturing.

[0022] 6. The turning point of the limiting groove is designed with an arc shape to avoid sharp edges and reduce the potential risk of scratching the user's skin or clothing during use; at the same time, the spring plate is made of stainless steel, which is corrosion-resistant and has lasting elasticity, further ensuring safety and comfort for long-term use.

Detailed Implementation

[0032] This utility model embodiment provides an earring locking mechanism 100 that facilitates alignment, solving the technical problem in the prior art where earring pins are difficult to quickly and accurately align with the through hole. This not only reduces wearing efficiency but may also cause the earring pins to bend or components to wear due to repeated attempts, affecting the lifespan and safety of the locking mechanism. It simplifies the process of inserting the earring pins and improves the convenience of wearing and user experience while maintaining a secure lock.

[0033] The technical solution in this utility model embodiment is to solve the above problems. The general idea is as follows: a guide tube 4 with an annular flange 41 is provided. The guide tube 4 passes through the first through hole 21 of the spring sheet 2, and the annular flange 41 is stuck between the spring sheet 2 and the locking piece 3. When the earring needle 1 is inserted, the guide tube 4 guides the earring needle 1 to avoid it being inserted crookedly.

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] Please refer to Figures 1 to 7 As shown, a preferred embodiment of the earring locking mechanism 100 for easy alignment according to this utility model includes: One earring pin; A spring sheet 2 has a first through hole 21 in the middle and two symmetrically bent upward elastic bending portions 22 on both sides, which are used to provide elastic force for the reset of the locking piece 3, that is, to restore the misalignment state of the third through hole 35 and the fourth through hole 36; the first through hole 21 is used to pass through the guide tube 4. A locking plate 3 has a second through hole 31 in the middle, and a covering part 32 for covering the spring plate 2 is provided at the front and rear edges of the second through hole 31; a limiting groove 33 is provided at the front and rear edges of the left and right sides of the second through hole 31; a limiting part 34 is provided at the end of the left and right sides respectively; a third through hole 35 is provided between the limiting groove 33 and the limiting part 34 on the left side, and a fourth through hole 36 is provided between the limiting groove 33 and the limiting part 34 on the right side; In the initial state, there is a misalignment between the third through hole 35 and the fourth through hole 36. It is necessary to press the locking piece 3 from both sides to align the third through hole 35 and the fourth through hole 36 before inserting the earring needle 1. The second through hole 31, the third through hole 35, and the fourth through hole 36 are used to pass through the earring needle 1. The covering part 32 is used to prevent the spring piece 2 from falling off. The limiting groove 33 is used to limit the limiting part 34, that is, to limit the displacement generated when the locking piece 3 is pressed. A guide tube 4 has an annular flange 41 at its top end; the outer diameter of the guide tube 4 matches the first through hole 21 and passes through the first through hole 21; the annular flange 41 is located between the spring plate 2 and the locking plate 3 and is used to limit the guide tube 4. Specifically, the guide tube 4 is made of a rigid or semi-rigid material (such as metal or hard plastic) with a smooth inner wall, forming a stable guiding channel. When the locking tab 3 wraps around the spring tab 2, the upper end of the guide tube 4 is precisely aligned with the second through hole 31 of the locking tab 3, while the lower end points to the channel entrance formed by the alignment of the third through hole 35 and the fourth through hole 36 under pressure. This structure ensures that the insertion path of the earring pin 1 is straight and accurate from the beginning.

[0036] The locking piece 3 is bent to wrap around the spring piece 2, so that the first through hole 21 is directly opposite the second through hole 31, and the two sides overlap each other at the top of the spring piece 2. The limiting part 34 on the right side is bent based on the limiting groove 33 on the left side, and the limiting part 34 on the left side is bent based on the limiting groove 33 on the right side. That is, a closed loop with an overlapping area is formed by bending the locking piece 3. The length of the guide tube 4 matches the closed loop, that is, the guide tube 4 is located inside the closed loop, and its end is close to the third through hole 35 and the fourth through hole 36. The earring needle 1 passes through the second through hole 31, the guide tube 4, the third through hole 35, and the fourth through hole 36 in sequence.

[0037] The end of the earring pin 1 is provided with several annular grooves 11 arranged side by side, which limit the spring plate 2 and the locking plate 3.

[0038] Each of the annular grooves 11 is spaced apart by a predetermined distance.

[0039] The second through hole 31, the third through hole 35 and the fourth through hole 36 are on the same axis.

[0040] The first distance between the third through hole 35 and the left edge and the second distance between the fourth through hole 36 and the right edge are equal. This symmetrical design ensures that after the locking tab 3 is bent and wrapped, the structure on the left and right sides is completely symmetrical and the force is even, making the pressing operation more stable and the through hole alignment process more reliable.

[0041] The spring sheet 2 is a stainless steel spring sheet.

[0042] The diameters of the first through hole 21, the second through hole 31, the third through hole 35, and the fourth through hole 36 are the same.

[0043] The inner diameter of the guide tube 4 matches the outer diameter of the earring needle 1. "Matching" means that the inner diameter of the guide tube 4 is slightly larger than the outer diameter of the earring needle 1, which can ensure that the earring needle 1 passes through smoothly and provide sufficient guiding accuracy to prevent the earring needle 1 from shaking excessively in the tube and ensure that the needle tip can accurately reach the position of the third through hole 35.

[0044] The turning point of the limiting groove 33 is arc-shaped.

[0045] Working principle of this utility model: Wearing: By squeezing the locking plate 3 from both sides, and then squeezing the spring plate 2, the misaligned third through hole 35 and fourth through hole 36 are made coaxial. Then, the earring pin 1 passes through the second through hole 31, guide tube 4, third through hole 35 and fourth through hole 36 in sequence, and falls into the two annular grooves 11 respectively. Then, the applied pressure is released to reset the spring plate 2. The third through hole 35 and fourth through hole 36 are misaligned under the elastic force of the spring plate 2, locking the spring plate 2 and locking plate 3 in the annular groove 11.

[0046] Disassembly: By squeezing the locking plate 3 from both sides, the spring plate 2 is squeezed, making the misaligned third through hole 35 and fourth through hole 36 coaxial, and then the earring needle 1 passes through the second through hole 31, guide tube 4, third through hole 35 and fourth through hole 36 in sequence.

[0047] In summary, the advantages of this utility model are as follows: 1. By introducing a guide tube with an annular flange at the top, and placing it below the second through hole of the locking plate after passing through the first through hole of the spring plate, a pre-aligned rigid guide channel is constructed.

While maintaining the secure locking function brought about by the bending structure of the locking plate and the misalignment of the through holes, it fundamentally improves the intuitiveness, speed, and success rate of wearing the earring, and optimizes the user experience.
