[0010] Furthermore, the bolt head is provided with a buckle groove around the column;

[0011] The bolt hole structure comprises a cavity for the bolt head to enter and exit, and a cavity arranged adjacent to the cavity. The upper side of the cavity has a narrow opening capable of clamping the buckle groove.

[0012] Furthermore, the female buckle has a step groove, and a through cavity penetrating the upper and lower ends of the female buckle is provided along the tread of the step groove, and a convex ring is provided in the through cavity to separate the through cavity into an upper cavity and a lower cavity.

[0013] Furthermore, the cover buckling mechanism includes:

[0014] The buckle cover has a buckle cavity with a lower opening, a connecting column is arranged in the buckle cavity, and a through hole for the bolt head to enter is arranged on a side of the buckle cavity facing the bolt head;

[0015] A spring, after the spring is sleeved on the connecting column, the buckle cover is placed in the step groove, so that the connecting column enters the through cavity from the first opening of the through cavity;

[0016] A screw enters the through cavity from the second opening of the through cavity and is connected to the connecting column, and a cap portion of the screw is defined by the convex ring.

[0017] Furthermore, the diameter of the tail section of the bolt head is equal to the diameter of the via hole.

[0018] Furthermore, the head of the bolt head is chamfered.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The buckle structure of the utility model is designed with a buckle cover mechanism, which cleverly buckles the bolt head, and then presses the buckle cover to make the buckle groove disengage from the narrow mouth, which is easy to operate. The buckle groove on the bolt head is stuck by the narrow mouth, and the bolt head is buckled stably and is not easy to be disengaged.

[0021] 2. The buckle cover mechanism of the utility model utilizes a spring to push the buckle cover tightly, so that the buckle cover moves up with the bolt head, and then the buckle groove enters the narrow mouth and is fully buckled. Due to the thrust of the spring, the connection between the sub-buckle and the mother buckle is stable. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the technical features involved in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment 1: The specific structure of the utility model is as follows:

[0031] Please refer to the attached Figure 1-4 The utility model provides a jewelry buckle with a buckle structure, comprising:

[0032] A sub-clasp 1, the clasp end of which has a protruding bolt head 2, and the sub-clasp 1 is connected to one end of the jewelry body, for example: the sub-clasp 1 is connected to one end of the bracelet body;

[0033] A female buckle 6, having a bolt hole structure for the bolt head 2 to enter and exit and capable of clamping the bolt head 2, and the female buckle 6 is connected to the other end of the bracelet body;

[0034] The buckle cover mechanism is installed on the female buckle 6 and clamps and unlocks the bolt head 2 by moving up and down.

[0035] A preferred technical solution of this embodiment: the bolt head 2 is provided with a buckle groove around the column, the two ends of the buckle groove are the tail section and the head of the bolt head 2 respectively, and the head of the bolt head 2 is chamfered, and the chamfered bolt head 2 is easier to enter the female buckle 6.

[0036] The bolt hole structure includes a cavity 11 for the bolt head 2 to enter and exit, and a chamber 3 arranged adjacent to the cavity 11. The upper side of the cavity 11 has a narrow opening that can clamp the buckle groove. Figure 3 The upper part of the cavity opening 11 shown in the figure has a narrow opening which is a semicircular notch, and the lower end of the cavity opening 11 is arc-shaped, and the size of the opening is sufficient for the bolt head 2 to enter and exit. The cavity 3 opens on the tread of the step groove, and the opening is a rectangular opening. Below the opening is a rectangular cavity, and the bottom of the cavity 3 is an arc bottom surface, and the arc bottom surface directly passes through the lower end of the mouth of the cavity opening 11.

[0037] A preferred technical solution of this embodiment: the female buckle 6 has a step groove, and a through cavity 4 is provided along the tread of the step groove, which passes through the upper and lower ends of the female buckle 6. A convex ring is provided in the through cavity 4 to separate the through cavity 4 into an upper cavity and a lower cavity. Figure 2 As shown, the through cavity 4 and the chamber are separated and close to each other.

[0038] A preferred technical solution of this embodiment: the cover buckling mechanism includes:

[0039] The buckle cover 10 has a buckle cavity 8 with a lower opening, a connecting column 9 is arranged in the buckle cavity 8, and a through hole 12 for the bolt head 2 to enter is arranged on a side of the buckle cavity 8 facing the bolt head 2;

[0040] A spring 7, after the spring 7 is sleeved on the connecting column 9, the buckle cover 10 is placed in the step groove, so that the connecting column 9 enters the through cavity 4 from the first opening of the through cavity;

[0041] The screw 5 enters the through cavity 4 from the second opening of the through cavity 4 and is connected to the connecting column 9, and the cap of the screw 5 is defined by the convex ring.

[0042] A preferred technical solution of this embodiment is that the diameter of the tail section of the bolt head 2 is equal to the diameter of the through hole 12 , and when the head of the bolt head 2 enters the chamber 3 , the through hole 12 and the tail section of the bolt head 2 fit perfectly.

[0043] Embodiment 2:

[0044] like Figure 5 As shown, Figure 5 This is a structural diagram of the utility model after the sub-button and the female button are fastened.

[0045] When the sub-buckle 1 and the mother buckle 6 need to be fastened, first, the buckle cover 10 needs to be pressed down so that the buckle cover 10 compresses the spring 7 downward and moves so that the through hole 12 on the buckle cover 10 and the wide part of the cavity 11 are opposite.

[0046] Then, the head of the bolt head 2 is inserted into the chamber 3 through the through hole 12 and the wide part of the cavity opening 11. At this time, the buckle groove is located directly below the narrow opening.

[0047] The buckle cover 10 is released, and the buckle cover 10 moves upward due to the recovery of the spring 7, so that the buckle cover 10 and the tail end of the bolt head 2 move upward synchronously, and then the buckle groove enters the narrow opening, and the buckle groove is stuck by the narrow opening. The buckle connection between the sub-buckle 1 and the female buckle 6 is completed.

[0048] Embodiment 3:

[0049] like Figure 6 As shown, Figure 6 It is a schematic diagram of the unbuttoning action of the child buckle and the mother buckle of the utility model.

[0050] Figure 6 There are arrows B and A in the figure. Press the buckle cover 10 downward in the direction of arrow B so that the through hole 12 and the wide part of the cavity opening 11 are aligned. Then press arrow A to withdraw the sub-buckle 1, and the bolt head 2 leaves the narrow opening. The sub-buckle 1 and the mother buckle 6 are separated to complete the unbuttoning action.

[0051] In summary, the buckle structure of the utility model is designed with a buckle cover mechanism, which cleverly buckles the bolt head 2, and then presses the buckle cover 10 to make the buckle groove disengage from the narrow mouth, which is easy to operate. The buckle groove on the bolt head 2 is stuck in the narrow mouth, and the bolt head is buckled stably and not easy to be disengaged. The buckle cover mechanism of the utility model uses the spring 7 to press the buckle cover 10, so that the buckle cover moves up with the bolt head, and then the buckle groove enters the narrow mouth and is completely buckled. Due to the thrust of the spring, the sub-buckle 1 and the mother buckle 6 are stably connected.

[0052] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present invention.
