Description

Technical Field

[0001] The utility model relates to the technical field of movable locks, in particular to a movable lock applied to jewelry and a jewelry piece equipped with the lock. Background Art

[0002] With the continuous improvement of living standards, people's enthusiasm for jewelry products is also increasing, and the categories and aesthetic requirements of jewelry are becoming more and more diversified. Necklaces, bracelets and earrings are the most common jewelry pieces, which have always been loved by consumers of all levels and ages and have become major consumer products.

[0003] For bracelets, bracelets and necklaces, there are styles with fixed connection structures that cannot be separated as a whole, and there are also styles that can be opened and closed through movable buckles. The most common chain buckles we see are elastic buckles or spring buckles, which are more common and traditional. These buckles have a single style and lack of shape changes. In addition, the elasticity will cause the spring to break and the buckle to break as the use time increases.

[0004] In addition, there are also locks on the market that use a push-type opening and closing, such as CN201721711140.5 push-type switch bracelet, which discloses that the push switch includes a shell with a cavity, one end of the bracelet body is fixedly connected to the push switch, and the other end is provided with a plug that can be inserted into the shell cavity, and the shell cavity is provided with a column and a push paddle, the push paddle is resisted on the column by a spring, and the push paddle includes a button and a paddle for snapping the plug, the button is exposed outside the shell and the surface of the button is provided with an inlay, and the button is pressed to disengage the paddle from the plug and pull out the plug. The problem with this type of push lock is that after a single press, the paddle immediately disengages from the buckle position, releasing the restriction on the plug, so the connected chain will be opened. In this way, there is a possibility of accidental touch, accidental pressing, and opening and falling off, which will cause the jewelry to fall.

[0005] We need to design and improve such a lock design to perform a two-way confirmation opening and closing process through two actions to avoid structural problems such as accidental touch and accidental opening. Summary of the invention

[0006] The utility model proposes a double-pressing jewelry buckle to solve the existing problems. The double-pressing jewelry buckle is designed to ensure the opening and closing action by pressing two structures at different positions. Only by pressing the two structures at different positions at the same time can the locking parts be opened smoothly to complete the process of connecting and loosening the jewelry rope chain.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0032] Please refer to the attached Figure 1 To Attachment Figure 3 : A double-pressing jewelry buckle is shown, including a lock buckle body 100 and connecting pins adapted at both ends of the lock buckle body 100 for connecting a rope chain, characterized in that the lock buckle body 100 includes a shell 10, a press buckle cover 20, a press spring 30, a side press buckle 40, and a compression spring 50, the press buckle cover 20 presses the press spring 30 and is assembled into the shell 10, and the shell 10 has an anti-drop limit for the press buckle cover 20; the two connecting pins include a first connecting pin 61 and a second connecting pin 6 2, wherein the first connecting pin 61 passes through the shell 10 and the push buckle cover 20 and is fixed in the lock body 100, the second connecting pin 62 passes through the shell 10 and is limited and clamped by the limiting groove on the push buckle cover 20, when the push buckle cover is pressed down, the limiting groove is separated from the limiting of the second connecting pin, and a side pressing buckle 40 is assembled on the side of the shell 10 through a compression spring 50, and one end of the side pressing buckle 40 buckles the lifting limiting groove 21 on the push buckle cover 20 to limit the downward pressure of the push buckle cover 20.

[0033] The insertion part of the connecting pin 61 / 62 into the lock body has a limiting head 611 and a limiting neck 612. The insertion part of the connecting pins at both ends of the pressing buckle cover 20 is provided with holes and slots. The fixed limiting slot 22 corresponds to the first connecting pin 61. The width of the fixed limiting slot 22 is larger than the limiting neck 612 of the connecting pin and smaller than the limiting head 611 of the connecting pin. The movable limiting slot 23 corresponding to the second connecting pin 62 on the pressing buckle cover 20 is larger than the limiting head 611 of the connecting pin. Therefore, when the first connecting pin 61 is inserted into the fixed limiting slot 22, it will be stuck in the pressing buckle cover 20.

[0034] Please refer to the attached Figure 5 , which shows a cross-sectional view when the connecting pin is installed in the lock body, the wall thickness of the movable limiting groove 23 on the pressing buckle cover 20 is less than the length of the limiting neck 612 of the connecting pin, and when the pressing buckle cover 20 is not subjected to external force, the movable limiting groove 23 is inserted into the limiting neck 612 of the connecting pin to limit the horizontal movement freedom of the connecting pin. At this time, the pressing buckle cover 20 itself is subjected to the outward push force of the internal pressing spring 30, and the movable limiting groove 23 will tightly lock the second connecting pin 62.

[0035] Please refer to the attached Figure 3 , wherein the fixed limiting groove 22 is a straight groove with an opening facing downward along the inner wall of the push buckle cover 20, and the movable limiting groove 23 is a closed groove without an opening. That is to say, when the push buckle cover 20 is assembled downward into the housing 10, the first connecting pin 61 that has been inserted into the housing 10 will slide into the push buckle cover 20 along the fixed limiting pin 22 facing the opening, and because the width of the fixed limiting groove is smaller than the limiting head 611, if the push buckle cover 20 does not withdraw from the housing 10, the first connecting pin 61 will always be locked and limited by the fixed limiting groove 22.

[0036] Please refer to the attached Figure 2 and attached Figure 3 , both show that the housing 10 has a through hole 11 of a size suitable for the connecting pin, and the size of the through hole 11 is suitable for the limiting head and the limiting neck of the connecting pin to be inserted therein. There is one through hole 11 on each side of the corresponding connecting pin.

[0037] Please refer to the attached Figure 3 and attached Figure 4 The side buckle 40 includes a connecting shaft seat 41, a pressing key body 42 and a buckle hook 43. The connecting shaft seat 41 is provided at the middle of the inner side of the pressing key body 42, and the buckle hook 43 is provided at one end of the inner side of the pressing key body 42.

[0038] A side hole 12 is provided on the housing 10 corresponding to the side pressing buckle 40 , and after the pressing buckle cover is assembled into the housing 10 , a lifting limit groove 21 is exposed corresponding to the side hole 12 .

[0039] The side buckle 40 is assembled to the side hole 12 of the outer shell 10 through a compression spring 50 hinged on the connecting shaft seat 41. The side hole 12 corresponds to the lifting limit groove 21 on the push buckle cover 20. The buckle hook 43 is adapted to be inserted into the lifting limit groove 21 on the push buckle cover to limit the freedom of the push buckle cover 20 to move up and down.

[0040] The housing 10 has an anti-drop limiter for the push buckle cover 20. The anti-drop limiter is that when the push buckle cover 20 is assembled into the housing 10 by pressing the pressing spring 30, it cannot drop out of the housing 10 and can only move toward the inside of the housing 10 under external force. Therefore, an anti-drop limiter structure needs to be designed in the structure. The limiter structure includes an inner clamping edge 13 of the housing 10 and an outer step clamping position 24 on the push buckle cover 20. The two cooperate with each other to form an anti-drop limiter structure of the housing 10 relative to the push buckle cover 20.

[0041] Therefore, it is not difficult to understand from the above structure and the description of the accompanying drawings that when the jewelry buckle needs to be loosened or locked, the pressing buckle cover 20 needs to be pressed downward. Only after pressing downward can the movable limit slot 23 be withdrawn from the limit neck 612 of the second connecting pin 62, and the second connecting pin 62 can be pulled out from the lock buckle body. In order to prevent the pressing buckle cover 20 from being accidentally touched or pressed, a side pressing buckle 40 is specially designed on the side of the shell. When the side pressing buckle is not moved, the downward movement of the pressing buckle cover 20 is limited. Therefore, the cleverness of the double pressing structure lies in that a side pressing buckle 40 and a pressing buckle cover 20 that actually fastens the connecting pin are designed from a structural point of view. Only when both are pressed can the action process of loosening the connecting pin / or opening the limit inserting the connecting pin be completely completed, and the locking and opening of the jewelry chain can be completed. And the situation of opening by accidental touching and colliding by mistake is completely avoided, and the jewelry is prevented from falling due to accidental touching and opening.

[0042] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Although the utility model is disclosed as a preferred embodiment as above, it is not used to limit the utility model. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content disclosed above without departing from the scope of the technical solution of the utility model. However, any simple modification, equivalent change and modification made to the above embodiments according to the technology of the utility model, which does not depart from the content of the technical solution of the utility model, belongs to the scope of the technical solution of the utility model.
