阅读说明：本技术 撑杆式的自锁托槽 (Strut-type self-ligating bracket ) 是由 陈贤明 林全红 周王峰 于 2020-05-29 设计创作，主要内容包括：本申请公开了撑杆式的自锁托槽,包括设有弓丝槽的基托、固定于基托底侧的网底、滑动安装于基托顶侧用于封闭或开放弓丝槽的锁片,基托上在朝向锁片的一侧开设有安装槽,安装槽内设有摆动的弹性件,弹性件的一端为与安装槽底部相抵的基准端,另一端为与锁片联动的驱动端,弹性件的摆动的路径上具有靠近弓丝槽的第一锁定位置和远离弓丝槽的第二锁定位置；在第一锁定位置下,弹性件的弹力驱使锁片封闭弓丝槽,在第二锁定位置下,弹性件的弹力驱使锁片开放弓丝槽。本申请通过弹性件的摆动来实现不同方向的弹力方向,确保弹性件工作状态的稳定性和锁片的运动的精度,避免了相关技术中弹性件变形后不能彻底恢复所引起的锁片功能下降或失效的情况。(The application discloses a supporting rod type self-locking bracket, which comprises a base provided with an arch wire groove, a net bottom fixed at the bottom side of the base, and a locking plate which is slidably arranged at the top side of the base and used for closing or opening the arch wire groove, wherein a mounting groove is formed in one side of the base facing the locking plate, a swinging elastic part is arranged in the mounting groove, one end of the elastic part is a reference end which is abutted against the bottom of the mounting groove, the other end of the elastic part is a driving end which is linked with the locking plate, and a first locking position close to the arch wire groove and a second locking position far away from the arch wire groove are arranged on the swinging path of the elastic; in the first locking position, the elastic force of the elastic part drives the locking plate to close the arch wire groove, and in the second locking position, the elastic force of the elastic part drives the locking plate to open the arch wire groove. The elastic direction of different directions is realized through the swing of elastic component to this application, ensures the stability of elastic component operating condition and the precision of the motion of locking plate, has avoided among the correlation technique the elastic component to warp the condition that can not thoroughly resume the locking plate function decline or the inefficacy that arouses.)

1. The strut-type self-locking bracket comprises a base provided with an arch wire groove, a net bottom fixed at the bottom side of the base and a locking plate slidably mounted at the top side of the base and used for closing or opening the arch wire groove, and is characterized in that a mounting groove is formed in one side of the base facing the locking plate, a swinging elastic part is arranged in the mounting groove, one end of the elastic part is a reference end abutted against the bottom of the mounting groove, the other end of the elastic part is a driving end linked with the locking plate, and a first locking position close to the arch wire groove and a second locking position far away from the arch wire groove are arranged on the swinging path of the elastic part;

under the first locking position, the elastic force of the elastic piece drives the locking plate to close the arch wire groove, and under the second locking position, the elastic force of the elastic piece drives the locking plate to open the arch wire groove.

2. The self-ligating bracket of claim 1, wherein the base includes two slots for constraining the sliding path of the locking tab, wherein the opposing sides of the locking tab are slidably engaged within the respective slots, and wherein the opening of the mounting slot is disposed between the two slots.

3. The self-ligating bracket of claim 2, wherein the sliding direction of the locking tab is a direction of a span of the mounting slot, the mounting slot gradually increasing in span from bottom to top to accommodate the swinging of the resilient member.

4. The self-ligating bracket of claim 3, wherein in the first locking position the resilient member abuts a wall of the mounting slot on a side of the mounting slot adjacent the archwire slot, and in the second locking position the resilient member abuts a wall of the mounting slot on a side of the mounting slot remote from the archwire slot.

5. The self-ligating bracket of claim 1, wherein the locking tab has a drive hole in a bottom surface thereof, wherein, in a sliding direction of the locking tab, an end of the drive hole proximal to the archwire slot is a first locking end and an end distal from the archwire slot is a second locking end;

the driving end is matched in the driving hole, and the driving end is pressed against the first locking end when the elastic piece is at the first locking position; and under the second locking position, the driving end of the elastic piece is pressed against the second locking end.

6. The self-ligating bracket of claim 5, wherein each of the first and second locking ends comprises a stop surface perpendicular to the direction of movement of the locking tab, and wherein the driving end and the reference end are movably pressed against the driving hole and the mounting slot, respectively.

7. The self-ligating bracket of claim 1, wherein an access slot is provided in the notch of the mounting slot adjacent the archwire slot for receiving a portion of the resilient member during installation of the locking tab to allow the locking tab to be installed in place.

8. The self-ligating bracket of claim 1, wherein the resilient member is a single or a plurality of cylindrical resilient rods made of nickel titanium.

9. The self-ligating bracket of claim 1, wherein the resilient member comprises a plurality of cylindrical resilient rods, each resilient rod being independent of each other or connected to each other in a frame configuration.

10. The self-ligating bracket of claim 1, wherein the resilient member is sheet-like.
