Description

Technical Field

[0001] This utility model relates to the field of bracelet technology, and more specifically, to a flexible opening and closing structure for a metal bracelet. Background Technology

[0002] Metal bracelets, as a traditional form of jewelry, are widely used in various cultures. Currently, most metal bracelets employ a fixed structure, requiring the wearer to pass their hand through a fixed opening. Due to the bracelet's rigid structure, this design can be inconvenient, especially for wearers with larger or smaller wrists, leading to difficulty or discomfort. Existing bracelets still have some shortcomings.

[0003] Utility model patent CN209660622U discloses a snap-on bracelet with a closable and detachable design. The bracelet includes a left half and a matching right half. A groove is provided at the end where the left and right halves connect, and a pressing structure is located inside the groove. This pressing structure includes a fixed shaft with a torsion spring sleeved on its outer side and a pressing latch at the top. A pressing latch tongue is provided at the end where the right and left halves connect. This invention, by having a left and right half bracelet, allows the left and right halves to be easily separated through a pressing latch and its tongue at one end. The other ends are movably connected via an adjusting block and an adjusting shaft; simply pulling out the pressing latch tongue at the end of the pressing latch separates the left and right halves. The aforementioned bracelet can be separated, but it does not have an elastic opening and closing function when in use. It cannot automatically disengage after being pressed to a certain extent. The existing locking structure requires pressing a specific component to disengage the internal locking structure, thereby achieving the separation function. This is very inconvenient to use, and the excessive mechanical structure increases the cost of the metal bracelet.

[0004] Therefore, we have made improvements to this by proposing a flexible opening and closing structure for metal bracelets. Utility Model Content

[0005] The purpose of this invention is to address the problem that existing bracelet opening and closing structures do not have elastic opening and closing functions and cannot automatically disengage after being pressed to a certain extent.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The flexible opening and closing structure of the metal bracelet is designed to improve the above-mentioned problems.

[0007] The application is as follows: It includes a first connecting ring, a connecting shaft mounted on the first connecting ring, a bushing mounted on the outside of the connecting shaft, a second connecting ring fixedly connected to the bushing, a connecting block mounted on the second connecting ring, an installation groove opened on the first connecting ring, a first magnetic block installed in the installation groove, and a third magnetic block installed on the connecting block.

[0008] As a preferred technical solution of this application, both the first connecting ring and the second connecting ring are semi-circular ring structures, and the bushing, the second connecting ring and the connecting block are fixedly connected as an integral structure.

[0009] As a preferred technical solution of this application, the outer wall of the connecting shaft and the inner wall of the bushing are in close contact with each other, the bushing is a spherical cover structure with an opening on the side near the first connecting ring, and the connecting shaft is a spherical structure.

[0010] As a preferred technical solution of this application, the second connecting ring forms a rotating structure with the first connecting ring through a connecting shaft and a bushing, wherein the center of the ball of the connecting shaft is located inside the bushing.

[0011] As a preferred technical solution of this application, the outer wall of the connecting block and the inner wall of the mounting groove are in close contact with each other, the connecting block is a fan-ring structure, and the center of the ball of the connecting shaft is located on the fan-ring axis of the connecting block.

[0012] As a preferred technical solution of this application, the outer wall of the first magnetic block is flush with the inner wall of the mounting groove, the magnetization direction of the first magnetic block is perpendicular to the magnetization direction of the third magnetic block, and the magnetic poles of the first magnetic block and the third magnetic block repel each other.

[0013] As a preferred technical solution of this application, a fourth magnetic block is fixedly connected to the rear side of the third magnetic block, and a second magnetic block is installed on the first connecting ring. The magnetic poles of the second magnetic block and the fourth magnetic block repel each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By setting the first and third magnetic blocks, the elastic opening and closing function is realized. Compared with the traditional structure that uses springs and mechanical buckles, this device has a simpler structure and lower cost. It uses the repulsive force between the two sets of magnetic blocks to achieve the locking function, which can not only quickly engage and connect, but also facilitate subsequent disassembly. It solves the problem that the existing bracelet opening and closing structure does not have an elastic opening and closing function and cannot automatically disengage after being pressed to a certain extent.

[0015] 2. By setting the second and fourth magnetic blocks, since the magnetic poles of the second and fourth magnetic blocks repel each other, and the magnetic poles of the first and third magnetic blocks repel each other, the connecting block that is slidably installed in the mounting groove has a certain resistance when rotating and pulling outward, ensuring that the connecting block is always inside the mounting groove when not subjected to external force, thus ensuring the stability of the first connecting ring and the second connecting ring after docking.

[0023] Example 1: like Figures 1-6 As shown, this embodiment proposes a flexible opening and closing structure for a metal bracelet, including a first connecting ring 1, a connecting shaft 2 mounted on the first connecting ring 1, a bushing 3 mounted on the outer side of the connecting shaft 2, a second connecting ring 4 fixedly connected to the bushing 3, a connecting block 5 mounted on the second connecting ring 4, an installation groove 6 formed on the first connecting ring 1, a first magnetic block 7 installed in the installation groove 6, and a third magnetic block 9 mounted on the connecting block 5. The magnetic poles of the first magnetic block 7 and the third magnetic block 9 are connected from... Figure 4 As can be seen, due to the mutual repulsion of magnetic poles, the connecting block 5 can be ensured to have resistance when moving up and down, thereby ensuring the stability of the first connecting ring 1 and the second connecting ring 4 after docking. When the connecting block 5 is detached from the mounting groove 6, the second connecting ring 4 can be rotated at any angle on the first connecting ring 1 by using the connecting shaft 2 and the bushing 3, which facilitates the quick wearing or removal of the bracelet and enhances the convenience of use.

[0024] Example 2: The following section provides a further description of the scheme in Example 1, focusing on its specific working method. See the description below for details: like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, the first connecting ring 1 and the second connecting ring 4 are both semi-circular ring structures. The bushing 3, the second connecting ring 4 and the connecting block 5 are fixedly connected as an integral structure. The first connecting ring 1 and the second connecting ring 4 of the semi-circular ring structure can rotate relative to each other, which facilitates the quick wearing and removal of the bracelet.

[0025] like Figure 5 As shown, in a preferred embodiment, based on the above method, the outer wall of the connecting shaft 2 and the inner wall of the bushing 3 are further fitted together. The bushing 3 is a spherical structure with an opening on the side near the first connecting ring 1. The connecting shaft 2 is a spherical structure. The bushing 3 can be rotated through the connecting shaft 2 so that the bracelet can be removed after the first connecting ring 1 and the second connecting ring 4 are disengaged.

[0026] like Figure 1 , Figure 2 and Figure 5 As shown, in a preferred embodiment, based on the above method, the second connecting ring 4 further forms a rotating structure with the first connecting ring 1 through the connecting shaft 2 and the bushing 3. The center of the ball of the connecting shaft 2 is located inside the bushing 3, and the bushing 3 can rotate outside the connecting shaft 2 without detaching from the connecting shaft 2, thus ensuring the overall stability.

[0027] like Figure 3 and Figure 5 As shown, in a preferred embodiment, based on the above method, the outer wall of the connecting block 5 is further fitted to the inner wall of the mounting groove 6. The connecting block 5 has a fan-ring structure, and the center of the ball of the connecting shaft 2 is located on the fan-ring axis of the connecting block 5, ensuring that after the two connecting rings are connected, the connecting block 5 can only be removed from the mounting groove 6 by rotation.

[0028] like Figure 4 As shown, in a preferred embodiment, based on the above method, the outer wall of the first magnetic block 7 is flush with the inner wall of the mounting groove 6, the magnetization direction of the first magnetic block 7 is perpendicular to the magnetization direction of the third magnetic block 9, and the magnetic poles of the first magnetic block 7 and the third magnetic block 9 repel each other. When the two connecting rings are connected, each magnetic block follows... Figure 4 The distribution pattern of the magnetic blocks creates resistance when the third magnetic block 9 moves up and down, thus enabling a flexible opening and closing function.

[0029] like Figure 4 As shown, in a preferred embodiment, based on the above method, a fourth magnetic block 10 is fixedly connected to the rear side of the third magnetic block 9, and a second magnetic block 8 is installed on the first connecting ring 1. The magnetic poles of the second magnetic block 8 and the fourth magnetic block 10 repel each other, and the fourth magnetic block 10 has resistance in the forward and backward movement direction, so as to ensure that the third magnetic block 9 remains stable after flexible docking.

[0030] Specifically, the flexible opening and closing structure of this metal bracelet, when used: ... Figures 1-4 As shown, the magnetic pole distribution and positions of the first magnetic block 7, the second magnetic block 8, the third magnetic block 9, and the fourth magnetic block 10 are shown from... Figure 4 As can be seen, since the third magnetic block 9 and the fourth magnetic block 10 are connected to the second connecting ring 4, and the first magnetic block 7 and the second magnetic block 8 are both installed on the first connecting ring 1, and the first magnetic block 7 and the second magnetic block 8 are located on the front and rear sides of the third magnetic block 9 and the fourth magnetic block 10 respectively, and the magnetic poles of the first magnetic block 7 and the third magnetic block 9 repel each other, and the magnetic poles of the second magnetic block 8 and the fourth magnetic block 10 repel each other, it can be ensured that there is resistance when the connecting block 5 moves up and down and forward and backward, thereby ensuring the stability of the first connecting ring 1 and the second connecting ring 4 after docking.

[0031] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, when the connecting block 5 is subjected to greater pressure and detaches from the mounting groove 6, the connecting shaft 2 and the bushing 3 can be used to allow the second connecting ring 4 to rotate at any angle on the first connecting ring 1, making it convenient to quickly put on or take off the bracelet.

[0032] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above.
