Description

Technical Field

[0001] This application relates to the field of bracelets, and more particularly to a bracelet locking structure. Background Technology

[0002] Bracelets are a common type of jewelry, made from a variety of materials such as gold, silver, and crystal. Each style of bracelet has a different shape, and people often match different styles of jewelry with their clothing or outfits.

[0003] Existing bracelet structures generally include a chain, a chain, and a locking mechanism. The chain is connected to one end of the chain, and the locking mechanism is connected to the other end of the chain. When the bracelet is worn, the locking mechanism is fastened to the chain, so that the chain, chain, and locking mechanism form a closed loop. When ornaments are placed on the bracelet, the chain is generally threaded onto the ornaments. The chain is generally in the form of a chain structure or a woven structure.

[0004] Regarding the aforementioned technologies, unlocking the locking mechanism currently requires considerable force to press and unlock. However, for older users or those with weakened finger strength due to arthritis or other reasons, it is often difficult to unlock the locking mechanism smoothly by simply pressing. Summary of the Invention

[0005] In order to enable various users to easily unlock the locking structure, this application provides a bracelet locking structure.

[0006] The bracelet locking structure provided in this application adopts the following technical solution:

[0007] A bracelet locking structure includes a locking body and an elastic element. The locking body has a locking hole for connecting the locking structure to the chain. The locking body includes a main body and a locking part, which are rotatably connected. The main body and the locking part are connected to form the locking hole. When the locking part rotates towards the main body, the locking hole opens. The locking part is connected to a driving block, and the driving block and the locking part are located on the same side of the main body. The elastic element is disposed on the locking body and is used to drive the locking part to reset so that the locking hole closes.

[0008] By adopting the above technical solution, when users with normal finger strength need to unlock the locking structure, they only need to press the locking part or lift the driving block, causing the locking part to rotate towards the main body, thereby opening the locking hole and unlocking the locking structure. When users with weakened finger strength need to unlock the locking structure, they place two fingers on the driving block and the locking part respectively. At this time, one finger lifts the driving block and the other finger presses down on the locking part, thus providing pressing and lifting forces on the locking part simultaneously. This increases the rotational torque of the locking part towards the main body, allowing users with weakened finger strength to provide sufficient torque to overcome the elastic force of the elastic element, causing the locking part to rotate towards the main body, opening the locking hole, and unlocking the locking structure. This allows all types of users to unlock the locking structure relatively easily, improving the current problem where unlocking the locking structure requires a large amount of force to press, but for older users or those with weakened finger strength due to arthritis or other reasons, it is often difficult to unlock the locking structure smoothly by simply pressing.

[0009] Optionally, the locking body further includes a rotating part, which is fixedly connected to the main body. The locking part has a through rotating hole. When the main body and the locking part are rotatably connected, the rotating part passes through the rotating hole and is rotatably connected to the locking part, so as to realize the rotatable connection between the main body and the locking part.

[0010] Optionally, the main body is provided with a first inclined surface that is inclined from the direction away from the axis of the locking hole toward the direction close to the axis of the locking hole, and the locking part is provided with a second inclined surface that is inclined from the direction close to the axis of the locking hole toward the direction away from the axis of the locking hole. When the locking hole is closed, the first inclined surface and the second inclined surface abut against each other, so that the elastic element is not likely to drive the locking part to continue to rotate away from the main body.

[0011] Optionally, the elastic element includes a locking torsion spring, one end of which is connected to the main body and the other end of which is connected to the locking part, so that after the locking structure is unlocked, the locking torsion spring pushes the locking part to reset, thereby relocking the locking structure.

[0012] Optionally, a connecting groove is provided at one end of the locking body, and the connecting groove is used to connect the locking structure with the chain.

[0013] Optionally, the connecting groove includes multiple hole sections, each of which has a cylindrical hole structure. The hole sections are evenly distributed around the vertical axis and are tangent to each other and connected to facilitate the connection between the connecting groove and the chain belt.

[0014] Optionally, the locking body is engraved with multiple patterned sides, each patterned side being evenly distributed along the vertical axis, and each patterned side being used to engrave patterns.

[0015] Optionally, the patterned side includes multiple patterned surfaces, and each patterned surface is connected in sequence to form a regular polygonal patterned side.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] When users with normal finger strength need to unlock the locking mechanism, they only need to press the locking part or lift the drive block, causing the locking part to rotate towards the main body, thus opening the locking hole and unlocking the locking mechanism. When users with weakened finger strength need to unlock the locking mechanism, they place two fingers on the drive block and the locking part respectively. At this time, one finger lifts the drive block and the other finger presses down on the locking part, thus providing pressing and lifting forces on the locking part simultaneously. This increases the rotational torque of the locking part towards the main body, allowing users with weakened finger strength to provide enough torque to overcome the elastic force of the elastic element, causing the locking part to rotate towards the main body, opening the locking hole and unlocking the locking mechanism. This allows all types of users to unlock the locking mechanism relatively easily, improving the current situation where unlocking the locking mechanism requires a lot of force to press and unlock. However, for older users or users with weakened finger strength due to arthritis or other reasons, it is often difficult to unlock the locking mechanism smoothly by simply pressing.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0033] This application discloses a bracelet locking structure. (Refer to...) Figures 1 to 4 A bracelet locking structure includes a locking body 1 and an elastic element 2. The locking body 1 has a through-hole 10 for connecting the locking structure to the chain. The locking body 1 has a through-hole 20 perpendicular to the axis of the locking hole 10. In this embodiment, the axis of the connecting hole 20 is set as a vertical axis.

[0034] Reference Figures 5 to 7 The locking body 1 includes a main body 11, a rotating part 12, and a locking part 13. The rotating part 12 is fixedly connected to one side of the main body 11. The locking part 13 has a through rotating hole 131 along the axis of the locking hole 10. The rotating part 12 passes through the rotating hole 131 and is rotatably connected to the locking part 13 to realize the rotatable connection between the main body 11 and the locking part 13. The main body 11 and the locking part 13 are connected to form the locking hole 10. When the locking part 13 rotates toward the main body 11, the locking hole 10 opens.

[0035] Reference Figures 5 to 7The elastic element 2 includes a locking torsion spring. In this embodiment, the elastic element 2 is selected as a locking torsion spring. One end of the locking torsion spring is connected to the main body 11, and the other end of the locking torsion spring is connected to the locking part 13. After the locking structure is unlocked, the locking torsion spring pushes the locking part 13 to reset so that the locking structure is relocked.

[0036] Reference Figures 5 to 7 The main body 11 is provided with a first inclined surface 111 that is inclined from the direction away from the axis of the locking hole 10 toward the direction closer to the axis of the locking hole 10, and the locking part 13 is provided with a second inclined surface 133 that is inclined from the direction close to the axis of the locking hole 10 toward the direction away from the axis of the locking hole 10. When the locking hole 10 is closed, the first inclined surface 111 and the second inclined surface 133 abut against each other so that the elastic member 2 is not likely to drive the locking part 13 to continue to rotate away from the main body 11.

[0037] Reference Figure 3 The locking body 1 has a connecting groove 30 at one end. The connecting groove 30 is used to connect the locking structure with the chain belt. The connecting groove 30 is connected to the connecting hole 20. The connecting groove 30 includes multiple hole parts 301. The hole structure of each hole part 301 is cylindrical. Each hole part 301 is evenly distributed around the vertical axis. The holes of each hole part 301 are tangent and connected to each other to facilitate the connection between the connecting groove 30 and the chain belt.

[0038] Reference Figure 4 The locking body 1 is engraved with multiple patterned sides 40. Each patterned side 40 is evenly distributed along the vertical axis. Each patterned side 40 is used to engrave patterns. Each patterned side 40 includes multiple patterned surfaces 401. Each patterned surface 401 is connected in sequence to form a regular polygonal patterned side 40.

[0039] Reference Figure 7 One end of the locking part 13 is fixedly connected to a driving block 132. The driving block 132 is rectangular, and both the driving block 132 and the locking part 13 are located on the same side of the main body 11.

[0040] The implementation principle of a bracelet locking structure in this application embodiment is as follows: When a user with normal finger strength needs to unlock the locking structure, the user only needs to press the locking part 13 or lift the driving block 132, causing the locking part 13 to rotate towards the main body 11, thereby opening the locking hole 10 and unlocking the locking structure. When a user with weakened finger strength needs to unlock the locking structure, the user places two fingers on the driving block 132 and the locking part 13 respectively. At this time, one finger lifts the driving block 132 and the other finger presses down on the locking part 13, thereby providing pressing and lifting forces on the locking part 13 simultaneously. The increased rotational torque that causes the locking part 13 to rotate closer to the main body 11 provides sufficient torque for users with weakened finger strength to overcome the elastic force of the elastic member 2, causing the locking part 13 to rotate closer to the main body 11, thereby opening the locking hole 10 and unlocking the locking structure. This allows various users to unlock the locking structure more easily, improving the current situation where unlocking the locking structure requires a large amount of force to press and unlock, which is often difficult for older users or those with weakened finger strength due to arthritis or other reasons to unlock the locking structure with simple pressing.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
