Description

a locking structure

technical field

The invention relates to a locking structure.

Background technique

The face of the ring is mostly fixed on the ring. Each ring is only one style, and the structure is monotonous. If you want to change the style, you have to buy it again. It is more expensive. If you spend a lot of money to buy a ring, it is a waste to throw it away or put it on hold because you don’t like the ring surface. In order to make customers spend less money and have a variety of different rings, some manufacturers put the ring It is processed separately from the ring surface, so there are many patent applications for changing the ring surface, but many patents disclose more complicated schemes, unreliable connections, and easy to drop when wearing, which will bring economic losses to customers.

Further, the locked part is provided with a fastening hole matching the cantilever and the bottom buckle.

Further, the second inner wall is opposite to the first inner wall.

Further, the base is a ring, and the locked part is a tulip.

Further, a locking post is provided on the inner wall of the shank, and a lock hole matching the locking post is provided at one end of the bottom buckle.

Further, the inner wall of the ring is provided with a groove for accommodating the bottom buckle, and the locking protrusion is arranged at the groove bottom of the groove.

Further, at least one chain hole is provided on the flower head.

Further, the swing arm of the bottom button is connected to the inner wall of the concave cavity through an elastic component.

Further, the base is a square block with a chain hole, and the locked part is a flower head.

Detailed ways

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be further described below in conjunction with the accompanying drawings.

Embodiment one

As shown in Figures 1 to 7, the locking structure of the present invention includes a base 1 and a locked part 2, wherein the base 1 is a ring ring, the locked parts 2 are several flower heads, and the base 1 The upper end is provided with a concave cavity 11, as shown in Figure 2, the first inner wall 111 of the concave cavity 11 is provided with a cantilever 3 perpendicular to the first inner wall 111 and extending toward the center of the concave cavity 11, on the second inner wall 112 of the concave cavity 11 A bottom buckle 4 that can swing in the concave cavity 11 is connected to the shaft, and the locking member 2 is buckled and connected to the cantilever 3 and the bottom buckle 4. Preferably, as shown in Figure 3, the flower head is provided with the cantilever 3 and the bottom buckle 4. /or the buckle hole 21 matched with the bottom buckle 4, and the second inner wall 112 is set opposite to the first inner wall 111, such a structure is more reasonable, so that the buckle hole 21 and the cantilever 3, the buckle hole 21 and the bottom buckle 4 The force of the ring is more uniform, and it is not easy to fall off, causing loss; the inner wall of the ring is provided with a locking post 5, and one end of the bottom buckle 4 is provided with a lock hole 41 matching the locking post 5, when the buckle is locked After the flower head, the swing arm at the lower end can be locked by the locking boss 5 to avoid loosening between the bottom buckle 4 and the flower head. Further, a groove 12 for accommodating the bottom buckle 4 is provided on the inner wall of the ring ring to lock it tightly. The boss 5 is arranged at the bottom of the groove 12, so that when the buckle is locked by the locking boss 5, the lower end swing arm of the bottom buckle 4 is accommodated in the groove 12, and the bottom buckle 4 and the inner wall of the ring ring Flush for a more comfortable fit.

When in use, a ring ring can be equipped with a plurality of flower heads of different styles, so that different wearing effects can be produced only by changing the flower heads, and at least one chain-through hole 22 is arranged on the flower heads, as shown in Figure 8, by placing the flower heads String on a chain of 6 and wear alone as a pendant.

Embodiment two

As shown in Figures 9 to 12, the difference between this embodiment and Embodiment 1 is that the base 1 is a jade square block with a chain hole 13, and the locked part 2 is also a flower head, and at the bottom The swing arm of buckle 4 is connected with the inwall of cavity 11 by an elastic component 7, and elastic component 7 is a compression spring, and one end of spring is connected with the swing arm of bottom button 4, and the other end is connected with the inwall of cavity 11, simultaneously The bottom end of the concave cavity 11 is sealed with a protective sheet 8 with a through hole 81 .

When the flower head is installed in the concave cavity, the tension spring is in a compressed state. Taking the direction shown in FIG. 11 as a reference, a leftward thrust is applied to the swing arm of the bottom button 4. The cantilever 3 securely buckles the flower head in the cavity 11 together; when changing the flower head, use a thimble to pass through the through hole 81 on the protective sheet 8, and apply an upward thrust to the swing arm of the bottom button 4, at this time The swing arm of the bottom button 4 moves counterclockwise around the rotating shaft to overcome the thrust of the spring and further compress the spring. At this time, the fastening end of the bottom button 4 moves to the left until the fastening end breaks away from the fastening hole 21 on the flower head. The flower head is removed and replaced. When the hanging chain hole 13 is put on the hanging chain, it can be matched into necklaces of different styles; the protective sheet 8 not only protects the bottom buckle 4 located in the concave cavity 11, but also makes the jade square block The bottom end is flatter and more comfortable to wear.

The present invention is firstly designed from the perspective of cost performance. By changing the angle of the swing arm of the bottom buckle 4, this locking structure is suitable for men's rings, hang tags, belt heads and other accessories, allowing customers to invest less cost and get more. In return, if consumers want to change a different style of ring, they only need to change the face of the ring instead of buying it again. At the same time, from the perspective of loss, this method makes jewelry more energy-saving and environmentally friendly; secondly, in order to cater to the market's individuality To meet the needs of fashion jewelry, the present invention can be worn for multiple purposes, and multiple products can be dismantled or combined to bring style changes, which means that only one product can have multiple functions, and multiple jewelry can be purchased There are thousands of changes, for example, it can be removed to make flower heads for women’s rings or bracelets, flower heads for earrings and belt heads, and can also be used directly as pendants. We can show different ourselves from each change, and each dimension makes us more beautiful. People keep in mind that it is not only economical, but also has a changeable structure, and the style can be changed at will.

The above are specific implementations of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also considered Be the protection scope of the present invention.
