Description

Technical Field

[0001] This utility model relates to the field of posture correctors, and specifically to a multi-adjustable posture corrector. Background Technology

[0002] As we all know, students often bend over, hunch their necks, or lie on their desks to read books. If they maintain this incorrect posture for a long time, it can cause spinal deformities or nearsightedness, which will affect their vision and normal physical development in the long run.

[0003] Therefore, ensuring students maintain correct posture during the learning process is especially important.

[0004] Although there are already posture correction devices on the market that can help students develop correct reading and writing postures, most of the existing posture correction devices are fixed to the edge of the desk and have a height-limiting frame to limit the sitting posture. For students of different heights and body types, the posture correction devices on the market have a narrow applicability to learning scenarios and to different people. The adjustment method is complicated and not suitable for the application of students in complex scenarios and with different body types. Utility Model Content

[0025] To make the technical solution of this utility model clearer, the present utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the terms "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] like Figure 1-7 As shown, the multi-end adjustable orthodontic device of this utility model includes a flat frame base 1, a movable seat 21 movably installed on one side of the flat frame base 1, and a third-segment adjustment component 2, a first-segment adjustment component 4, and a second-segment adjustment component 3, which are rotatably adjustable at both ends and telescopically adjustable in the middle. At the connection between the flat frame base 1 and the movable seat 21, there is a sleeve wheel 23, a spring 22, and a pressure cap 25 that cooperate with the third-segment adjustment component 2 for rotational adjustment and limiting. The spring 22 presses against the sleeve wheel 23 inserted at the connection between the flat frame base 1 and the movable seat 21. The second-segment adjustment component 3 is provided with a telescopic seat 31 that cooperates with the movable seat 21 for height adjustment, and the telescopic seat 31 is movably connected to the movable seat 21. The first-segment adjustment component 4 is provided with an orthodontic baffle assembly 41 that cooperates with the telescopic seat 31 for rotational adjustment.

[0027] In this embodiment, a through connecting screw 5 is provided at the connection between the flat frame base 1 and the movable base 21.

[0028] In this embodiment, one end of the pressure cap 25 is exposed on the surface of the movable seat 21, and the other end of the pressure cap 25 is in contact with the side of the sleeve wheel 23.

[0029] In this embodiment, the pressure cover 25 is provided with a protrusion 26 protruding to the side, and the positional relationship between the pressure cover 25 and the movable seat 21 is limited by the cooperation between the protrusion 26 and the movable seat 21.

[0030] In this embodiment, the sleeve wheel 23 is provided with locking teeth 24 and locking grooves 27. The locking teeth 24 restrict the angular relationship between the movable seat 21 and the flat frame seat 1. When the sleeve wheel 23 overcomes the elastic force of the spring 22 and retracts into the flat frame seat 1, the movable seat 21 rotates on the flat frame seat 1 through the connecting screw 5.

[0031] In this embodiment, the movable seat 21 has at least two slots 35 arranged vertically inside.

[0032] In this embodiment, the telescopic seat 31 is provided with a swing arm 33, a compression spring 32, a limiting slope 37, a hinge column 36, and a pressure cap 38. The hinge column 36 is fixed on the telescopic seat 31, the swing arm 33 is sleeved on the hinge column 36 and can rotate, and the compression spring 32 presses the swing arm 33 against the limiting slope 37 through elastic force; the pressure cap 38 is transversely inserted into the telescopic seat 31, and one end of the pressure cap 38 presses against one end of the swing arm 33.

[0033] In this embodiment, the swing arm 33 is provided with a locking post 34 fixedly connected to the swing arm 33. The height relationship between the movable seat 21 and the telescopic seat 31 is limited by the cooperation between the locking post 34 and the locking groove 35.

[0034] In this embodiment, the rotation object of the first segment adjustment component 4 is to correct the angular relationship between the baffle component 41 and the telescopic seat 31.

[0035] In this embodiment, the angle limiting relationship between the correction baffle assembly 41 and the telescopic seat 31 on the first segment adjustment assembly 4 is the same as that of the third segment adjustment assembly 2.

[0036] When using

[0037] First, place the flat frame 1 on the table. Then, press down the pressure cap 38 and pull the telescopic seat 31 to adjust the corrective baffle assembly 41 to fit the body height. During this process, the swing arm 33 inside the telescopic seat 31 overcomes the elastic force of the compression spring 32 under the pressure of the pressure cap 38. The swing arm 33 rotates on the hinge column 36, causing the locking column 34 to engage in the locking groove 35 of the movable seat 21, thereby limiting the height relationship between the telescopic seat 31 and the movable seat 21. Release the pressure cap 38, and the swing arm 33 adheres to the limiting slope 37 under the elastic force of the compression spring 32. At the same time, the locking column 34 engages in the locking groove 35 of the movable seat 21. When the pressure cap 38 is pressed down again and the telescopic seat 31 is pulled, the height can be readjusted.

[0038] Furthermore, it is necessary to adjust the third-segment adjustment component 2 and the first-segment adjustment component 4 so that the angle of the upper and lower ends of the multi-end adjustable orthodont can be rotated to adapt to different learning scenarios and different groups of people; next, press the cover 25, at this time the cover 25 pushes the sleeve wheel 23 to overcome the elastic force of the spring 22 and return to the flat frame 1, and then the movable seat 21 can rotate on the flat frame 1 through the connecting screw 5; after releasing the cover 25, the sleeve wheel 23 slides to the junction of the flat frame 1 and the movable seat 21, and the sleeve wheel 23 restricts the angle relationship between the movable seat 21 and the flat frame 1 through the locking tooth 24. The operation is simple and convenient.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
