Technical Field
[0001] This utility model relates to the field of connecting buckle technology, specifically to an adjustable-angle jewelry buckle. Background Technology
[0002] Clasps are one of the most common connecting devices in jewelry, used to connect the two ends of a piece of jewelry. They are widely used in necklaces, bracelets, and even watches. As a visual focal point, the stability and viewing angle of jewelry when hanging are crucial, directly determining the overall decorative effect and wearing experience. Currently, traditional clasp structures mainly focus on connection and locking, typically using a straight connection structure to ensure that the necklace forms a closed loop and is securely worn around the neck. However, simple straight connection structures cannot meet the design requirements of jewelry and are difficult to adapt to the personalized experience requirements of the wearer. Summary of the Invention
[0003] In view of the defects of the existing technology, the purpose of this utility model is to provide an adjustable angle jewelry buckle that can adjust the included angle between the two connecting ends of the buckle while retaining the safe connection function of the traditional buckle, so as to meet the wearer's usage requirements.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an adjustable-angle jewelry clasp, comprising a bottom cover, a floating seat, and an outer shell. The outer shell is fixedly connected to the top of the bottom cover. The floating seat is rotatably disposed within the inner cavity of the outer shell and positioned by a positioning component. The floating seat is floatingly disposed on the bottom cover by a floating spring. A limiting stop is provided at the top of the outer shell to limit the extreme position of the top of the floating seat. A fixed terminal and a movable terminal are connected to the floating seat. The fixed terminal is fixedly connected to the floating seat. The outer shell is provided with a fixed terminal rotation groove corresponding to the position of the fixed terminal. The fixed terminal rotates within the range of the fixed terminal rotation groove, driving the floating seat to rotate within the inner cavity of the outer shell. The outer shell is provided with a socket for inserting the movable terminal. The floating seat is provided with a movable terminal rotation groove for assembling the movable terminal. The movable terminal rotates relative to the floating seat within the range of the movable terminal rotation groove.
[0005] Furthermore, a wave-shaped structure with uniformly positioned grooves is formed on the inner surface of the outer shell. The protruding part of the wave-shaped structure abuts against the outer peripheral surface of the floating seat to ensure that the floating seat is coaxial with the outer shell. The positioning component includes a positioning spring and a ball bearing. A storage groove is provided on the outer wall of the floating seat. The ball bearing is connected to the storage groove through the positioning spring. By rotating the floating seat, the positioning assembly of the ball bearing with different positioning grooves is achieved, thereby fixing the floating seat in a staged position within the outer shell.
[0006] Furthermore, the wave-shaped structure on the inner surface of the floating seat has a smooth transition in the circumferential direction; the part of the wave ball that contacts the inner surface of the floating seat is a spherical structure, the rear end of the spherical structure is a cylindrical structure and is inserted into the inner hole of the positioning spring, and the other end of the positioning spring is fixedly connected to the bottom of the receiving groove of the floating seat, and the positioning spring is always kept in a compressed state.
[0007] Furthermore, the fixed terminal is threadedly connected to the floating seat.
[0008] Furthermore, both the fixed terminal rotating groove and the movable terminal rotating groove are arc-shaped grooves, and the arc center angles corresponding to them are the same.
[0009] Furthermore, the head end of the movable terminal is expanded to form a hemispherical head structure, which is assembled in the rotating groove of the movable terminal. When the floating seat is at the bottom limit position, the rotating groove of the movable terminal of the floating seat is flush with the insertion hole of the housing. When the floating seat is at the top limit position, the rotating groove of the movable terminal of the floating seat and the insertion hole of the housing are misaligned in height, thus confining the hemispherical head structure of the movable terminal within the insertion hole of the housing.
[0010] Furthermore, a longitudinal mounting groove is provided at the center of the bottom of the floating seat, the top of the floating spring abuts against the bottom of the mounting groove, the bottom of the floating spring is fixedly connected to the bottom cover, and the floating spring is always kept in a compressed state.
[0011] Furthermore, the top of the floating seat has a pressing part exposed outside the outer shell.
[0012] Furthermore, a pressing part protruding from the outer shell is formed on the top of the floating seat.
[0013] Furthermore, the fixed terminal and the movable terminal are respectively connected to both ends of the jewelry chain link.
[0014] The beneficial effects of this utility model are as follows: the connection structure and angle adjustment mechanism are integrated through the cooperation between the floating seat and the outer shell, so that the relative angle between the fixed terminal and the movable terminal of the buckle can be manually adjusted and fixed to meet the needs of jewelry design.

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0017] See appendix Figure 1-2 An adjustable-angle jewelry clasp includes a base cover 1, a floating seat 2, and an outer shell 3. The main body of the jewelry clasp is circular, and the main bodies of the base cover 1, floating seat 2, and outer shell 3 are all circular. The outer shell 3 is fixedly connected to the top of the base cover 1. The floating seat 2 is rotatably disposed within the inner cavity of the outer shell 3 and positioned by a positioning component. The floating seat 2 is floatingly disposed on the base cover 1 by a floating spring 4. The top of the outer shell 3 is provided with a limiting stop 301 that restricts the extreme position of the top of the floating seat. The top of the floating seat 2 has a pressing part 204 protruding from the top of the outer shell 3. Pressing the pressing part 204 from top to bottom compresses the floating spring 4. The floating seat 2 retracts and moves down to contact the bottom cover 1; a fixed terminal 5 and a movable terminal 6 are connected to the floating seat 3; the fixed terminal 5 is fixedly connected to the floating seat 2, and the outer shell 3 is provided with a fixed terminal rotation groove 302 corresponding to the position of the fixed terminal 5. The fixed terminal 5 rotates within the range of the fixed terminal rotation groove 302, driving the floating seat 2 to rotate within the cavity of the outer shell 3; the outer shell 3 is provided with a socket 303 for inserting the movable terminal 6, and the floating seat 2 is provided with a movable terminal rotation groove 201 for assembling the movable terminal 6. The movable terminal 6 rotates relative to the floating seat 2 within the range of the movable terminal rotation groove 201.
[0018] Furthermore, the inner surface of the outer shell 3 forms a wave-shaped structure with uniformly spaced positioning grooves 304. The protruding part of the wave-shaped structure abuts against the outer peripheral surface of the floating seat 2, ensuring that the floating seat 2 and the outer shell 3 are coaxial. The positioning assembly includes a positioning spring 7 and a ball bearing 8. A storage groove 202 is provided on the outer wall of the floating seat 2. The ball bearing 8 is connected to the storage groove through the positioning spring 7. By rotating the floating seat 2, the ball bearing 8 is positioned and assembled with different positioning grooves 304, thereby achieving a staged position fixation of the floating seat 2 within the outer shell 3. When the floating seat 2 moves up and down within the outer shell 3, the ball bearing 8 moves up and down along the positioning grooves 304.
[0019] To reduce vibration during the rotation of the floating seat 2, the wave-shaped structure on the inner surface of the floating seat 2 has a smooth transition in the circumferential direction. The part of the ball that contacts the inner surface of the floating seat is a spherical structure, and the rear end of the spherical structure is a cylindrical structure that is inserted into the inner hole of the positioning spring. The other end of the positioning spring is fixedly connected to the bottom of the receiving groove of the floating seat, and the positioning spring is always kept in a compressed state. During the rotation of the floating seat 2, when the positioning component of the floating seat 2 is opposite to the positioning groove 304 on the inner surface of the outer shell 3, the positioning spring 7 is released, causing the ball 8 to extend out. The spherical structure of the ball 8 is assembled into the positioning groove 304, thereby fixing the position of the floating seat 2 and the outer shell 3. When the positioning component of the floating seat 2 is opposite to the convex part on the inner surface of the outer shell 3, the positioning spring 7 contracts, storing the ball 8 into the receiving groove 202. After passing the convex point, the ball 8 is gradually released until it matches and is positioned with a positioning groove 304.
[0020] For the purpose of a detachable design between the fixed terminal 5 and the floating seat 2, the fixed terminal 5 and the floating seat 2 are threaded together.
[0021] Furthermore, both the fixed terminal rotating groove 302 and the movable terminal rotating groove 201 are arc-shaped grooves, and their corresponding arc center angles are the same, meaning that the maximum rotation angles of the fixed terminal 5 and the movable terminal 6 are the same. The maximum angle between the fixed terminal 5 and the movable terminal 6 is 180°. The fixed terminal 5 and the movable terminal 6 are respectively connected to the two ends of the jewelry chain link. By adjusting the angle between the fixed terminal 5 and the movable terminal 6, the hanging angle of the jewelry chain link can be adjusted to meet the design requirements and the user's personalized adjustment needs.
[0022] Furthermore, the head end of the movable terminal 6 is expanded to form a hemispherical head structure, which is assembled in the movable terminal rotation groove 201. When the floating seat 2 is in the bottom limit position, the movable terminal rotation groove 201 of the floating seat 2 is flush with the insertion hole 303 of the outer shell. When the floating seat 2 is in the top limit position, the movable terminal rotation groove 201 of the floating seat 2 and the insertion hole 303 of the outer shell are misaligned in height, so that the connection between the two is reduced, thereby clamping the movable terminal and restricting the hemispherical head structure of the large-diameter movable terminal 6 within the insertion hole 303 of the outer shell 3.
[0023] Furthermore, the bottom center of the floating seat 2 is provided with a longitudinal mounting groove 203, the top of the floating spring 4 abuts against the bottom of the mounting groove 203, the bottom of the floating spring 4 is fixedly connected to the bottom cover 1, and the floating spring 4 is always kept in a compressed state.
[0024] Instructions for use: Press down on the pressing part of the floating seat 2 to compress the floating spring 4, causing the floating seat 2 to move downwards. The rotating slot 201 of the movable terminal of the floating seat 2 aligns with the insertion hole 303 of the outer casing, allowing the movable terminal 6 to be pulled out. During installation, first press down on the pressing part of the floating seat 2, then insert the movable terminal 6. The fixed terminal 5 can rotate along the rotating slot 302 and is fixed in position by the ball bearing 8 to adjust the angle of the necklace. The key feature is that a single component can simultaneously meet both rotation and snap-fit requirements, satisfying the snap-fit connection while allowing for angle adjustment according to user preference.
[0025] This utility model is an innovative buckle design that integrates connection security and angle adjustability. It allows for angle adjustment while performing a buckle connection; it is compact, easy to operate, and aesthetically pleasing.
