A catching groove 4 parallel to the groove 25 is provided on the upper portion of the second side wall 24 of the second base portion 22.

The bracket bottom plate 1 is connected with the base 2 through a connector, so that the bracket bottom plate 1 and the base 2 are suspended in the air, and in the embodiment, the connector is three connecting columns arranged in an isosceles triangle. The connecting columns at the bottom edges of the isosceles triangles are respectively a first connecting column 31 and a second connecting column 32, and the connecting column at the top point is a third connecting column 33. Wherein the first connecting column 31 and the second connecting column 32 are located below the first base 21 and the third connecting column 33 is located below the second base 22.

As shown in fig. 2, the slide cover 5 is a sheet structure with a U-shaped cross section, and includes a slide 51 for sliding in the slide 34, a card 52 with a terminal capable of being inserted into the card slot 4, and a connecting piece 53 connecting the slide 51 and the card 52, where the slide 51 and the card 52 are respectively located on two arms of the U-shape. The space between the first connecting post 31 and the second connecting post 32 is a slide 34 for receiving a slide 51. The free end of the slide 51 is provided with a latch arm 54 extending outward of the slide 51 in a direction perpendicular to the sliding direction of the slide 51. The sliding piece 51 may be provided with a pressing groove 55 in the same direction as the sliding direction of the sliding piece 51, for increasing the deformation margin of the sliding piece 51 in the sliding way 34, so as to increase the flexibility of the sliding piece 51 in sliding. The length of the pressing groove 55 can be adapted to the position of the third connecting rod 33 on the sliding piece 51 when the sliding piece 51 moves forward to the limit position.

As shown in fig. 3, the space between the first connecting column 31 and the second connecting column 32 forms a slide 34, and the outer edge of the sliding piece 51 is in interference fit with the inner wall of the slide 34 (the surface opposite to the first connecting column 31 and the second connecting column 32), that is, the width of the sliding piece 51 is slightly larger than the width between the first connecting column 31 and the second connecting column 32. The sliding piece 51 can only slide forwards or backwards in the slideway 34 under the action of external force, and when the external force disappears, the sliding piece 51 is clamped at the current position between the first connecting post 31 and the second connecting post 32. For convenience of use, the card 52 is further provided with a through operation hole 56, which is convenient for a doctor to use a probe to perform an action of entering the card slot 4 or exiting the card slot 4 on the tail end of the card 52.

As shown in fig. 4 and 6, when the sliding piece 51 slides forward in the sliding track 34, the third connecting rod 33 can enter the pressing groove 55, the card 52 also slides forward along with the sliding piece 51, when the sliding piece 51 slides to the limit position, the end of the card 52 is clamped into the card slot 4 and fixed, and the pressing groove 55 reaches the third connecting rod 33 in parallel with the inner edge of the slot 25. The slide 51 is now clipped into position with the tab 52 overlying the slot 25, the tab 52 and slot 25 together forming an archwire slot for receiving an archwire.

As shown in fig. 5 and 7, when the sliding piece 51 slides backwards in the slideway 34 to the limit position, the first connecting column 31 and the second connecting column 32 respectively abut against the clamping arms 54 at two sides of the free end of the sliding piece 51, the clamping piece 52 slides backwards along with the sliding piece, the tail end of the clamping piece 52 is pulled out of the clamping groove 4 until the tail end of the clamping piece 52 reaches the upper part of the first base part 21, at the moment, the sliding piece 51 is clamped in the current position in the slideway 34, the upper part of the groove 25 is opened to form an arch wire inlet-outlet, and an arch wire can be placed into or moved out of the groove 25 through the arch.

As shown in fig. 8, 9, and 10, the self-ligating bracket of the present embodiment may first form the bracket base plate 1 and the base 2, first assemble the sliding cover 5 and the base 2, and then connect the bracket base plate 1 and the base 2 together through the first connecting post 31, the second connecting post 32, and the third connecting post 33.

Example 2:

as shown in fig. 11 and 14, the present embodiment is different from embodiment 1 in that the connecting body is an L-shaped connecting bar 35 disposed on both sides of the slide sheet 51, the short sides 36 of the two connecting bars 35 are disposed opposite to each other, and the space between the ends of the two short sides 36 forms the slide way 34. The outer edge of the slide 51 is in interference fit with the slide 34, i.e. the width of the slide 51 is slightly larger than the width between the ends of the two short sides 36. The sliding piece 51 can only slide forwards or backwards in the slideway 34 under the action of external force, and when the external force disappears, the sliding piece 51 is clamped at the current position between the tail ends of the two short sides 36.

As shown in fig. 12, the distance between the long sides of the connecting bars 35 is greater than the width of the free end of the slider 51 so that the slider 51 can slide between the connecting bars 35. When the slide 51 is slid backwards to the limit position, as shown in fig. 13, the catch arm 54 on the free end of the slide 51 is stopped by the short side of the connecting bar 35, so that the slide 51 cannot be completely released from the slide 34.

As shown in fig. 15, since the slide cover 5 is integrated with each other, when the slide 51 in the slide 34 slides from the first base 21 to the second base 22 by an external force, the card 52 also slides forward. As shown in fig. 16, until the end of the tab 52 is snapped into the slot 4 and secured, the slide 51 is snapped into place with the tab 52 overlying the slot 25, the tab 52 and slot 25 together forming an archwire slot for receiving an archwire.

Example 3:

as shown in fig. 17, the present embodiment is different from embodiment 1 in that the number of connecting columns is 4, wherein the first connecting column 31 and the second connecting column 32 are disposed below the first base portion, and the fourth connecting column 37 and the fifth connecting column 38 are disposed below the second base portion. The space between the first connecting column 31 and the second connecting column 32 is a slideway 34.

As shown in fig. 18, the end of the sliding piece 51 needs to slide forward in the sliding channel 34 under the action of external force, and when the end of the card 52 is clamped in the card slot 4, the end clamping arm 54 of the sliding piece 51 also passes over the fourth connecting column 37 and the fifth connecting column 38 to form a fixing for the sliding cover 5. As shown in fig. 19, 20 and 21, when the card 52 needs to be ejected from the card slot 4, the sliding piece 51 under the action of external force, the tail end of the clamping arm 54 firstly passes backwards through the fourth connecting column 37 and the fifth connecting column 38, and then slides backwards in the sliding way 34 until the clamping arm 54 is blocked by the first connecting column 31 and the second connecting column 32, so that the sliding piece 51 can only slide within the range limited by the connecting columns.

Example 4:

as shown in fig. 22, the present embodiment is different from embodiment 1 in that the slide piece 51 has a "mountain" shape, and includes a main body 56 extending in the sliding direction and two trailing arms 57 extending in the same direction on both sides of the main body 56. Wherein the space between the main body 56 and the trailing arm 57 is in interference fit with the first connecting column 31/the second connecting column 32, i.e. the width between the main body 56 and the trailing arm 57 is slightly smaller than the width of the first connecting column 31/the second connecting column 32. When the first connecting post 31/the second connecting post 32 is installed, the first connecting post 31/the second connecting post 32 must pass through the space between the main body 56 and the longitudinal arm 57, the sliding piece 51 can only slide forwards or backwards within the range limited by the first connecting post 31/the second connecting post 32 under the action of external force, and when the external force disappears, the sliding piece 51 is clamped at the current position by the main body 56 and the longitudinal arm 57.

In order to limit the backward movement range of the sliding piece 51, the end of the longitudinal arm 57 is bent toward the main body 56, and when the sliding piece 51 moves backward to the limit position, the end of the longitudinal arm 57 is blocked by the first connecting column 31/the second connecting column 32, so that the first connecting column 31/the second connecting column 32 cannot be pulled out from the space between the main body 56 and the longitudinal arm 57.

As shown in fig. 23 and 24, the third connecting post 33 may be configured as a rectangular block along the slot direction, so that the sliding piece 51 can slide back and forth under the restriction of the first connecting post 31/the second connecting post 32 by slight deformation of the trailing arm 57, but cannot pass through the third connecting post 33 by large deformation.

As shown in fig. 25, 26 and 27, the first connecting rod 31/the second connecting rod 32 passes through the space between the main body 56 and the trailing arm 57, and the sliding piece 51 needs to slide under the restriction of the first connecting rod 31/the second connecting rod 32 under the action of external force. When the end of the card 52 is clamped into the card slot 4, the first connecting column 31/the second connecting column 32 reaches the gingival direction of the sliding piece 51, and when the card 52 needs to be pulled out of the card slot 4, the first connecting column 31/the second connecting column 32 reaches the occlusal direction of the sliding piece 51.

It should be noted that the above-described embodiments can enable those skilled in the art to more fully understand the present invention, but do not limit the present invention in any way. Therefore, although the present invention has been described in detail with reference to the drawings and examples, it will be understood by those skilled in the art that the present invention may be modified and replaced by other means without departing from the spirit and scope of the present invention.
