The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Example 1:

as shown in fig. 1-4, the embodiment provides an arc metal self-locking appliance, which includes a base 1, an appliance main body 2 detachably disposed on the top of the base 1 through a plug-in component, an arch wire installation groove 3 disposed on the appliance main body 2 for installing an arch wire, an arc cover 4 slidably disposed on the appliance main body 2 through a latch component and used for limiting the arch wire, a driving component used in cooperation with the plug-in component is further disposed on the appliance main body 2, and a plurality of tightening components are further disposed between the base 1 and the appliance main body 2. Through setting up the grafting subassembly, can make and rescue ware main part 2 and base 1 and be connected with the mode of pegging graft, realize the components of a whole that can function independently setting of correcting ware main part 2 and base 1, need not whole preparation when the preparation, can separately make to aim at ground and rescue ware main part 2 or base 1, greatly reduced the cost of manufacture.

Two trapezoidal spacing grooves 6 have been seted up to arc lid 4 bottom front and back symmetry, and the fixed trapezoidal fixed block 5 that is equipped with sliding connection in trapezoidal spacing groove 6 in the top of correcting ware main part 2. Through the cooperation of trapezoidal spacing groove 6 and the trapezoidal fixed fast, play limiting displacement to arc lid 4, improve its motion stability.

The clamping component comprises a first limiting hole 9, a transition groove 8 and a second limiting hole 10 which are sequentially formed in the bottom of the cover plate from left to right, the top of the appliance main body 2 is provided with a limiting pipe 7 which is connected in the transition groove 8 in a sliding mode, and the limiting pipe 7 is located between the two trapezoid fixing blocks 5. Through setting up the joint subassembly, play limiting displacement to the position of arc lid 4, shelter from when spacing to the arch wire, help making arc lid 4 cover the arch wire steadily. When arc lid 4 seals arch wire mounting groove 3, slide arc lid 4 and seal on arch wire mounting groove 3, spacing pipe 7 enters into transition groove 8 from spacing hole two 10, along with the relative displacement of arc lid 4, enter into the hole body one through crossing transition groove 8, thereby spacing pipe 7 will resume to natural state and by spacing in spacing hole one 9, arc lid 4 has sealed arch wire mounting groove 3 and has sufficient locking force this moment, and because arc lid 4 is full-covered structure, arc lid 4 covers arch wire mounting groove 3 completely, arc lid 4 has been guaranteed to have had the contact of sufficient length with the arch wire, thereby possess good torque control. The full-covering structure of the arc-shaped cover 4 ensures that the outer surface of the product is smooth and round in a closed state, and the stimulation to the mucosa of the inner wall of the oral cavity is small.

The plug-in connection subassembly is including offering the mounting groove 12 at base 1 top, rotating the section of thick bamboo 13 of rotating in mounting groove 12 bottom, set up in 2 bottoms of appearance ware main parts and can insert the post 14 of inserting in rotating the section of thick bamboo 13, set up on inserting the post 14 and become threaded bulge loop 15, set up in the wedge fixture block 16 that rotates the inside wall of section of thick bamboo 13, wedge fixture block 16 and bulge loop 15 looks lock joint. By arranging the inserting assembly, the inserting column 14 can be inserted into the rotating cylinder 13, and the inserting column 14 and the rotating cylinder 13 are directly pressed and fixed during inserting; because the convex ring 15 is in a thread shape, the driving component can be used for enabling the inserting column 14 to withdraw in a mode of screwing the rotating cylinder 13 to rotate, so that the inserting column 14 and the rotating cylinder 13 are convenient to fasten and are difficult to remove.

The wedge-shaped fixture block 16 is provided with a guide inclined surface 23 for guiding the convex ring 15 to rapidly enter the rotating cylinder 13. The guide slope 23 is provided to facilitate the snap-in of the protruding ring 15.

The driving assembly is arranged to rotate the rotating cylinder 13 by rotating the rotating rod 19, so that the inserting column 14 can be withdrawn from the rotating cylinder 13. When the appliance main body 2 is separated from the base 1 by using the plug-in component and the driving component, the rotating rod 19 is rotated, the rotating rod 19 drives the bevel gear II 18 to rotate, the bevel gear II 18 drives the bevel gear I17 to rotate, the bevel gear I17 drives the rotating cylinder 13 to rotate, the rotating cylinder 13 drives the wedge-shaped fixture block 16 to rotate, the wedge-shaped fixture block 16 drives the convex ring 15 to rotate, and the plug post 14 is withdrawn from the rotating cylinder 13 in the rotating process of the convex ring 15.

The jacking component comprises a plurality of slots 20 evenly arranged at the top of the appliance main body 2, a plurality of jacking springs 22 arranged at the bottom in the slots 20, a mounting plate 21 positioned in the slots 20 and fixedly arranged at the tops of the jacking springs 22, a mandril 11 which is arranged at the opening of the slot 20 and fixedly connected with the bottom of the appliance main body 2 in a penetrating manner, and the bottom of the mandril 11 is abutted to the mounting plate 21. The setting of the tight subassembly in top, ejector pin 11 can push up mounting panel 21 when using, utilizes the elasticity of pushing up spring 22, makes ejector pin 11 receive ascending top tight power, can make the more stable of inserting post 14 and a rotating cylinder 13 grafting.

A micro sealing rubber pad 24 is arranged between the base 1 and the appliance main body 2, the micro sealing rubber pad 24 is in a ring shape, and the micro sealing rubber pad 24 is positioned outside the plurality of grooves 20. Through setting up sealing rubber pad, play sealed effect to the clearance between base 1 and the ware main part 2 of correcting, can avoid impurity to get into in mounting groove 12 or fluting 20 through this clearance.

The working principle is as follows: through setting up the joint subassembly, play limiting displacement to the position of arc lid 4, shelter from when spacing to the arch wire, help making arc lid 4 cover the arch wire steadily. When the arc cover 4 closes the arch wire placing groove 3, the arc cover 4 is closed on the arch wire placing groove 3 in a sliding mode, the limiting pipe 7 enters the transition groove 8 from the second limiting hole 10, along with relative displacement with the arc cover 4, the limiting pipe 7 enters the first hole body through the transition groove 8, the limiting pipe 7 is restored to a natural state and is limited in the first limiting hole 9, the arc cover 4 closes the arch wire placing groove 3 and has enough locking force, and because the arc cover 4 is of a full-covering structure, the arc cover 4 completely covers the arch wire placing groove 3, the arc cover 4 is guaranteed to be in contact with an arch wire with enough length, and good torque control is achieved. When the appliance main body 2 is separated from the base 1 by using the plug-in component and the driving component, the rotating rod 19 is rotated, the rotating rod 19 drives the bevel gear II 18 to rotate, the bevel gear II 18 drives the bevel gear I17 to rotate, the bevel gear I17 drives the rotating cylinder 13 to rotate, the rotating cylinder 13 drives the wedge-shaped fixture block 16 to rotate, the wedge-shaped fixture block 16 drives the convex ring 15 to rotate, and the plug post 14 is withdrawn from the rotating cylinder 13 in the rotating process of the convex ring 15.
