The chest support member and the connecting part are elastically and movably connected, and the two can move closer to each other or further apart. The chest support member has at least one extension post, which can be movably inserted into the connecting part. The electronic module is provided with a trigger switch, which is located at the end of the stroke of the extension post.

[0004] However, the aforementioned existing technologies still have the following shortcomings:

[0005] Because everyone's physical condition and habits are different, everyone's requirements for the width of the chest support are different. However, the chest support of the above-mentioned existing technology is a fixed structure and the width cannot be adjusted, which makes the posture corrector ineffective for some people and applicable to a small number of people. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the existing technology by proposing a chest expansion structure for an orthodontic device, which solves the technical problem mentioned in the background art that the chest expansion component of the existing technology is a fixed structure and cannot meet the needs of different users.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A chest expansion structure for an orthosis includes a mounting plate. Two symmetrically arranged chest supports are slidably mounted on one end of the mounting plate. The mounting plate has a cavity, and a linkage assembly is provided within the cavity. The linkage assembly includes a crank and two connecting rods. A connecting shaft is fixed at the middle of one end of the crank. The inner wall of the cavity has a limiting groove for the connecting shaft to be embedded in. The connecting shaft is rotatably mounted in the limiting groove. Two symmetrically arranged limiting posts are fixed at the other end of the crank. The connecting rods have circular holes for the limiting posts to pass through. Both ends of the connecting rods have connectors. The inner wall of the cavity has two symmetrically arranged sliding grooves. The connectors at one end of the connecting rods are embedded in the sliding grooves. The mounting plate has two symmetrically arranged sliding holes that communicate with the cavity. One end of the chest support has a circular groove, and the connector at the other end of the connecting rod passes through the sliding hole and is embedded in the corresponding circular groove.

[0009] Working principle:

[0010] When using the product, drag one of the breast supports on the left or right side outwards. The breast supports on the left / right side and the connecting rods on the left / right side will each move outwards by the same distance under the action of the crank. Therefore, dragging either breast support on the left or right side will cause the other one to move outwards by the same distance in the opposite direction.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention features a linkage component that allows users to drag either the left or right side of the chest bra, and the other bra will automatically move in the opposite direction by the same distance. This makes it easy for users to adjust the position of the two chest bras according to their needs, and it is simple to operate and has a wide range of applications. Attached Figure Description

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figure 1-7As shown, a chest expansion structure for an orthosis includes a mounting plate 1. Two symmetrically arranged chest supports 2 are slidably mounted on one end of the mounting plate 1. The mounting plate 1 has a cavity, and a linkage assembly is provided within the cavity. The linkage assembly includes a crank 3 and two connecting rods 4. A connecting shaft 5 is fixed at the middle of one end of the crank 3. The inner wall of the cavity has a limiting groove 6 for the connecting shaft 5 to be embedded in the limiting groove 6. The connecting shaft 5 on the crank 3 is embedded in the limiting groove 6 and is rotatably disposed within the limiting groove 6. Two symmetrically arranged limiting posts 7 are fixed at the other end of the crank 3. The connecting rods 4 have... A circular hole 8 is provided for the limiting post 7 to pass through. One end of the connecting rod 4 has an opening 21 that connects to the circular hole 8. The opening 21 is smaller than the radius of the limiting post 7. The opening 21 of the connecting rod 4 is elastic. A stop block 20 is fixed to one end of the limiting post 7 that passes through the circular hole 8. The stop block 20 is in contact with the corresponding end of the connecting rod 4. The opening 21 expands due to elastic deformation, which locks the limiting post 7 into it and prevents the connecting rod 4 from detaching from the crank 3. Therefore, when the left and right connecting rods 4 are subjected to force, they drive the crank 3 to move simultaneously. At the same time, the stop block 20 can also prevent the left and right connecting rods 4 from moving upwards. The movement disengages from crank 3. Both ends of the connecting rod 4 have connectors 9. The inner wall of the cavity has two symmetrically arranged sliding grooves 10. One end of the connector 9 of the connecting rod 4 is embedded in a sliding groove 10. The length of the sliding groove 10 limits the horizontal movement distance of the two connecting rods 4 and the two chest support plates 2. The mounting plate 1 has two symmetrically arranged sliding holes 11, which communicate with the cavity. One end of the chest support 2 has a circular groove 22. The other end of the connector 9 of the connecting rod 4 passes through the sliding hole 11 and is embedded in the corresponding circular groove 22. The other end of the chest support 2 is connected to the connector 9. Because of the rotational connection, when the chest support 2 is dragged, the two connecting rods 4 on the left and right sides move in both directions under the action of the crank 3. One end of the chest support 2 has a slider 23, which is embedded in the corresponding sliding hole 11. The circular groove 22 is opened on the slider 23. One end of each of the two chest supports 2 has a protrusion 19, which is close to one end of the top chest cover plate 13. The protrusion 19 at the bottom of the chest support 2 is used to compensate for the assembly gap between the chest support 2 and the top chest cover plate 13. At the same time, the friction between the two is small, and the chest support 2 moves smoothly.

[0024] like Figure 2-5As shown in Figure 8, the mounting plate 1 includes a top chest body 12 and a top chest cover 13. The top chest cover 13 has a first groove 14 and a second groove 24 at the opposite end to the top chest body 12. The top chest cover 13 is connected to the opposite end of the top chest body 12. The first groove 14 and the second groove 24 merge to form a cavity. Two sliding holes 11 are opened on the top chest cover 13. The limiting groove 6 and the two sliding grooves 10 are all provided on the inner wall of the second groove 24. The inner wall of the groove 14 has a positioning post 15, and the crank 3 has a positioning hole 16 for the positioning post 15 to be embedded. One end of the positioning hole 16 passes through the connecting shaft 5. One end of the top chest cover plate 13 is fixed with two sets of symmetrically arranged limiting groups. The limiting group includes two locking blocks 17. One end of the chest support 2 has a guide groove 18 for the corresponding two locking blocks 17 to be embedded. The bottom surface of the hook abuts against the surface of the sliding groove 10, so the chest support 2 can move in the horizontal direction.

[0025] The specific operation method of this utility model is as follows:

[0026] When in use, drag one of the chest supports 2 in one direction and make it move horizontally. The left and right chest supports 2 and the left and right connecting rods 4 will each move horizontally by the same distance under the action of the crank 3. Therefore, dragging either the left or right chest support 2 will cause the other to automatically move horizontally by the same distance in the opposite direction.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
