Description

Technical Field

[0001] The present invention belongs to the technical field of jewelry accessories, and particularly relates to a toggle plate structure connecting lock. Background Art

[0002] In jewelry accessories, the function of a buckle is to connect and fix the two ends of a necklace or bracelet together. And for some buckles, in order to fix the middle pressing plate, a central axis is required to be fixed, that is, a through hole is drilled in the middle of the buckle, which affects the overall aesthetics of the jewelry and the value of the ornament. Moreover, such a buckle will produce a large gap during manual production and is prone to looseness.

[0003] In the traditional way of making a buckle, small holes need to be drilled on both sides of the buckle body, and a connecting shaft is passed through the middle of the small holes to fix the button and the buckle body. To achieve the effect of a complete buckle body surface, both sides of the connecting shaft need to go through processes such as filling materials, welding, grinding, and polishing. The process is cumbersome and defective products are likely to appear, which cannot be repaired, time-consuming and laborious, and the size of the connecting shaft should be appropriate. If it is too thin, there is no supporting force, and if it is too thick, the filling materials and welding in the later stage cannot achieve a perfect effect. This structural feature is also the technical drawback and processing difficulty of such a buckle. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The present invention will be further explained below with reference to the drawings and embodiments.

[0027] As Figure 1-7As shown in the figure, the present invention is a toggle-type structure connecting lock, and the lock includes a lock body 1, a rod needle 2, a joint 3, an installation cavity 4, a toggle 5, a rod needle hole 6, a screw connection hole 7, an elastic connector fixing groove 8, a spring fixing groove 9, a spring piece fixing protrusion 10, an elastic connector 11, a spring 12, a rod needle pressing plate 13, a middle connecting column 14, a spring connecting protrusion 15, a side connecting protrusion 16, an arc-shaped groove 17, a side connecting hole 18, a bottom connecting hole 19, a screw 20, a pin 21, and a knurling 22.

[0028] An installation cavity 4 is formed in the lock body 1. A rod needle hole 6 is formed on one side of the lock body 1, and the shape of the part of the rod needle 2 inserted into the lock body matches the shape of the rod needle hole 6. A screw connection hole 7 is formed on the other side of the lock body 1, and the screw connection hole matches the screw 20. The rod needle hole 6 and the screw connection hole 7 communicate with the installation cavity 4, and the lock body 1 and the joint 3 are connected by the screw 20.

[0029] The bottom of the installation cavity 4 is provided with an elastic connector fixing groove 8, and the bottom of the elastic connector fixing groove 8 matches the bottom of the elastic connector 11. The elastic connector 11 is of an elastic connector structure, specifically a U-shaped spring piece, with a bottom connecting hole 19 at the bottom and side connecting holes 18 opened at the upper parts of both sides. The bottom of the elastic connector 11 is placed in the elastic connector fixing groove 8. A spring piece fixing protrusion 10 is provided in the middle of the elastic connector fixing groove 8. The bottom connecting hole 19 at the bottom of the elastic connector 11 is inserted into the spring piece fixing protrusion 10. The outer edge of the spring piece fixing protrusion 10 matches the bottom connecting hole 19 of the elastic connector 11, and the spring piece fixing protrusion 10 is a split structure of two semi-cylindrical bodies. During processing, the two semi-cylindrical protrusions are hammered downward with a tool to deform, so as to fix the elastic connector 11.

[0030] The outer shape structure of the lock body 1 can be made into any shaped structure form.

[0031] A seesaw 5 is provided on the upper part of the installation cavity 4, and the seesaw 5 covers the entire upper part of the installation cavity. A middle connecting column 14 is provided in the middle of the seesaw 5, and side connecting protrusions 16 are provided on both sides of the middle connecting column 14. The side connecting protrusions 16 match the side connecting holes 18 of the elastic connecting member 11.

The side connecting protrusions 16 match the side connecting holes 18 of the U-shaped spring piece. The distance between the side connecting protrusions on both sides of the seesaw is greater than the distance between the side connecting holes 18 of the U-shaped spring piece. The upper surface of the U-shaped spring piece is slightly arced on both sides, and the arc surface is to make the side connecting protrusions 16 easily slide into the side connecting holes 18 of the U-shaped spring piece. The seesaw 5 utilizes the elastic properties of the elastic connector 11 to fix the connecting protrusions 16 on both sides of the middle connecting column 14 of the seesaw 5 in the side connecting holes 18 provided on both sides of the U-shaped spring sheet, so that the seesaw 5 and the elastic connector 11 are firmly connected together, and the bottom of the elastic connector 11 is fixed to the buckle body through the spring sheet fixing protrusion 10. An arc groove 17 is provided in the middle of the seesaw 5, and the arc groove 17 matches the arc shape of the top of the elastic connector 11, and there is a movable distance between the two. This facilitates the smooth transition between the press release of the seesaw and the top of the elastic connector 11 without getting stuck.

[0032] The bottom of the installation cavity 4 is provided with a spring fixing groove 9 on one side of the elastic connector fixing groove 8, and the spring fixing groove 9 matches the outer ring of the spring 12. A spring connecting protrusion 15 is provided on one side of the rocker 5, and the spring connecting protrusion 15 matches the inner ring of the spring 12. The spring is vertically placed between the spring fixing groove 9 and the spring connecting protrusion 15. The rocker 5 is provided with an embossing 22 on the corresponding side of the spring to increase the pressing friction.

[0033] The side of the seesaw 5 connected to the knitting needle is provided with a knitting needle pressing plate 13, and the bottom of the knitting needle pressing plate 13 matches the neck of the knitting needle 2. The knitting needle is inserted into the knitting needle hole 6, and the knitting needle pressing plate 13 is clamped on the neck of the knitting needle 2 to achieve the purpose of clamping the knitting needle. The joint 3 and the lock body 1 are fixed by screws 20, and cylindrical pins 21 are provided in the tail tubes of the joint 3 and the knitting needle 2 for fixing the chain. The ends of the knitting needle 2 and the joint 3 are fixedly connected to the two ends of the bracelet or necklace.

[0034] When in use, press one end of the seesaw spring to make the needle pressure plate end tilt up, insert needle 2, release the seesaw spring end to make the seesaw needle pressure plate end fall down, and the needle pressure plate clamps the needle neck to achieve a fixed connection.

[0035] The above are specific embodiments of the present invention and the technical principles used. Any equivalent transformation based on the technical solution of the present invention belongs to the protection scope of the present invention.
