[0023] like Figure 1 As shown, an embodiment of the present application provides a 360-degree rotating and tilting lifting seat device, the device comprising:

[0024] A seat surface 1; a spherical adjustment mechanism, the spherical adjustment mechanism is fixedly connected below the seat surface; a locking mechanism, the locking mechanism is arranged on one side of the spherical adjustment mechanism and connected to the spherical adjustment mechanism; a lifting device 2, the lifting device is fixedly connected below the spherical adjustment mechanism; wherein, after the locking mechanism is applied with an external force and rotated in a first direction, the spherical adjustment mechanism is in an active state, the seat surface is applied with a horizontal force and rotated 360 degrees in a horizontal direction, and the seat surface is applied with a vertical force and tilted 360 degrees in a vertical direction; wherein, after the locking mechanism is applied with an external force and rotated in a second direction, the spherical adjustment mechanism is in a fixed state, and the rotation angle and tilt angle of the seat surface are fixed.

[0025] Specifically, in this embodiment, Figure 1 This is an exploded view of the assembly of the lifting seat device. Figure 1 The relative positions and assembly sequence of the several components of the lift seat device are shown, showing in three dimensions how each component will be connected in the final assembly.

[0026] based on Figure 1 It can be seen that a conical countersunk hole is provided on the seat surface 1, and the spherical adjustment mechanism is fixedly connected to the bottom of the seat surface 1. The spherical adjustment mechanism enables the seat surface 1 to rotate 360 ​​degrees in the horizontal direction and tilt 360 degrees in the vertical direction to adapt to the body shape and rehabilitation training needs of different users.

[0027] The locking mechanism is used to control the active state of the spherical adjustment mechanism. The locking mechanism locks and unlocks the spherical adjustment mechanism by rotating.

[0028] When the locking mechanism is rotated in a first direction (e.g., counterclockwise), the spherical adjustment mechanism is activated, allowing the user to adjust the rotation and tilt angles of the seat surface 1 as desired. When the locking mechanism is rotated in a second direction (e.g., clockwise), the spherical adjustment mechanism is fixed, locking the current rotation and tilt angles of the seat surface 1 to maintain the user's set posture.

[0029] The lifting device 2 is located below the spherical adjustment mechanism and is used to adjust the height of the lifting seat. Through the lifting device 2, the user can adjust the height of the seat according to his or her height or usage habits to obtain a more comfortable sitting posture.

[0030] Through multi-directional adjustment, the chair can adapt to the patient's pathological condition, compensate for angle differences, and thus improve training quality.

[0031] Furthermore, in this embodiment, the spherical adjustment mechanism includes:

[0032] A connecting splint 3, which is arranged at the upper end of the spherical adjustment mechanism, and the spherical adjustment mechanism is fixedly connected to the seat surface 1 through the connecting splint 3; a ball socket, which is fixedly connected below the connecting splint 3, wherein a hemispherical groove is provided on the inner surface of the ball socket; a composite spherical component 4, which includes a spherical portion and a supporting portion; the spherical portion is arranged in the hemispherical groove of the ball socket; the lower end of the supporting portion is fixedly connected to the lifting device 2.

[0033] Furthermore, in this embodiment, the ball seat includes:

[0034] The first split ball seat 5, the inner surface of the first split ball seat 5 is provided with an arc-shaped groove, and the first split ball seat 5 is provided with a through hole; the second split ball seat 6, the inner surface of the second split ball seat 6 is provided with an arc-shaped groove, and the second split ball seat 6 is provided with a locking threaded hole; the first split ball seat 5 and the second split ball seat 6 are fixedly connected to form the ball seat, and the arc-shaped grooves of the first split ball seat 5 and the second split ball seat 6 cooperate with each other to form a hemispherical groove.

[0035] Specifically, in this embodiment, the connecting splint 3 is the upper end component of the spherical adjustment mechanism, which is fixed under the seat surface 1. The function of the connecting splint 3 is to fix the spherical adjustment mechanism to the seat surface 1 to ensure that the seat surface 1 can rotate and tilt around the spherical adjustment mechanism.

[0036] The ball seat is used to realize the horizontal and vertical rotation and tilt of the seat surface 1. The ball seat is composed of two split ball seats: a first split ball seat 5 and a second split ball seat 6. The first split ball seat 5 and the second split ball seat 6 are fixedly connected to form a complete ball seat.

[0037] The inner surface of the first split ball seat 5 is provided with an arcuate groove, which cooperates with the arcuate groove of the second split ball seat 6 to form a hemispherical groove. In addition, the first split ball seat 5 is also provided with a through hole, which is used to install the locking mechanism.

[0038] The second split ball seat 6 is similar to the first split ball seat 5, and an arc-shaped groove is also provided on the inner surface, and a locking threaded hole is provided on the same line as the through hole. When the locking mechanism passes through the through hole of the first split ball seat 5 and is screwed into the locking threaded hole of the second split ball seat 6, the first split ball seat 5 and the second split ball seat 6 can be tightened to form a whole, thereby achieving the fixation of the rotation and tilt angle of the seat surface 1.

[0039] The composite spherical component 4 consists of two parts: a spherical part and a supporting part. The spherical part is placed in the hemispherical groove of the ball seat, allowing the seat surface 1 to rotate 360 ​​degrees around the spherical part. The supporting part connects the spherical part and the lifting device 2, supporting the seat surface 1 and allowing the seat surface 1 to move up and down.

[0040] Furthermore, in this embodiment, the connecting splint 3 includes:

[0041] A first connecting plate; a second connecting plate; the second connecting plate is fixedly connected between the first split ball seat 5 and the second split ball seat 6; the spherical adjustment mechanism is fixedly connected to the seat surface 1 through the first connecting plate.

[0042] Specifically, in this embodiment, the connecting plate 3 has a T-shaped structure. One horizontal portion of the T-shape (i.e., the first connecting plate) is connected to the seat surface 1, while the vertical portion (i.e., the second connecting plate) is connected to the ball seat. The first and second connecting plates are fixed together by the T-shaped connection structure to form an integral connecting plate 3.

[0043] A threaded through hole is provided on the first connecting plate, and the conical countersunk hole provided on the seat surface 1 is fixedly connected to the first connecting plate and the seat surface 1 by a countersunk screw 8 passing through the conical countersunk hole of the seat surface 1 and the threaded through hole on the first connecting plate, ensuring that the seat surface 1 can be stably installed on the connecting splint 3.

[0044] The first split ball seat 5 is provided with a mounting countersunk hole, and the second split ball seat 6 is provided with a threaded hole for fixing in addition to a locking threaded hole for the locking handle 7. A through hole is provided on the second connecting plate. The first split ball seat 5 and the second split ball seat 6 are fixedly connected by a cylindrical head screw 9 passing through the mounting countersunk hole and the threaded hole. The second connecting plate is placed between the first split ball seat 5 and the second split ball seat 6, and the cylindrical head screw 9 passes through the through hole on the second connecting plate.

[0045] Furthermore, in this embodiment, the locking mechanism includes:

[0046] A locking handle 7 passes through the through hole on the first split ball seat 5 and cooperates with the locking threaded hole on the second split ball seat 6.

[0047] Specifically, in this embodiment, the locking handle 7 is "L"-shaped and is the operating part of the locking mechanism. The user locks and unlocks the spherical adjustment mechanism by rotating this handle. Specifically, there is a thread on the locking handle 7, and the thread cooperates with the locking threaded hole of the second split ball seat 6.

[0048] The locking handle 7 passes through the through hole on the first split ball seat 5 and extends to the locking threaded hole of the second split ball seat 6. When the locking handle 7 passes through the through hole of the first split ball seat 5 and is screwed into the locking threaded hole of the second split ball seat 6, the two split ball seats can be tightened so that the spherical part of the composite spherical component 4 is fixed in a specific relative position in the hemispherical grooves of the first split ball seat 5 and the second split ball seat 6, and cannot rotate or move in the groove, and the rotation of the seat surface 1 around the spherical part is restricted.

[0049] This ensures that the seat surface 1 remains in the position set by the user, providing a stable sitting posture suitable for rehabilitation training or other activities that require a fixed sitting posture.

[0050] Furthermore, in one embodiment, the lifting device 2 includes:

[0051] A top connecting structure, wherein the top connecting structure is fixedly connected to the lower end of the support portion; a column structure, wherein the column structure is fixedly connected below the top connecting structure; and a side threaded component, wherein the side threaded component is arranged on one side of the column structure and connected to the column structure.

[0052] Furthermore, in one embodiment, the column structure includes:

[0053] A first lifting column; a second lifting column, wherein the first lifting column is sleeved inside the second lifting column; wherein, when the side threaded component is rotated in a third direction by an external force applied thereto, the second lifting column is in an active state, and the first lifting column is slid in a vertical direction by an external force applied thereto; wherein, when the side threaded component is rotated in a fourth direction by an external force applied thereto, the second lifting column is in a fixed state.

[0054] Specifically, in this embodiment, the top connection structure is the upper part of the lifting device 2, which is fixedly connected to the lower end of the support part. The function of the top connection structure is to connect the lifting device 2 with the spherical adjustment mechanism.

[0055] Specifically, the support portion is "T"-shaped; a through hole for fixing is provided on the bottom cube of the support portion; a threaded hole is provided on the top connecting structure of the lifting device, and the two are connected by a cylindrical head screw 9.

[0056] The column structure is the main part of the lifting device 2 and includes a first lifting column (inner column) and a second lifting column (outer column). The first lifting column (inner column) is a vertically sliding column that fits inside the second lifting column. The sliding of the first lifting column allows the height of the seat surface 1 to be adjusted. The second lifting column (outer column) is a fixed column, inside which the first lifting column slides, providing guidance and support for the first lifting column's sliding.

[0057] The side threaded component is the adjustment part of the lifting device 2 and is arranged on one side of the column structure. The side threaded component allows the user to control the movement of the lifting device 2 by rotating it. Specifically, when the side threaded component is applied with an external force and rotated in a third direction (for example, clockwise), the second lifting column is activated, allowing the first lifting column to slide in a vertical direction, thereby adjusting the height of the seat surface 1. This operation is usually called the "loose" state, allowing height adjustment.

[0058] When an external force is applied to the side threaded component to rotate in a fourth direction (for example, counterclockwise), the second lifting column is in a fixed state. At this time, the first lifting column is locked in the current position and the height of the seat surface 1 is fixed. This operation is usually called the "locked" state, which ensures that the seat surface 1 remains stable after being adjusted to the appropriate height.

[0059] The second lifting column includes: an outer column, which is provided with a through hole; a base fixing member, which is fixedly connected to the lower end of the outer column; the first lifting column is sleeved inside the outer column; and the side threaded component is connected to the column structure through the through hole.

[0060] like Figure 2 The figure shows the overall structure of a 360-degree rotating and tilting lifting seat device provided by the present application.

[0061] The technical solution provided by this application has at least the following technical effects or advantages:

[0062] 1. The 360-degree rotating and tilting lifting seat design can adjust the seat's tilt angle according to the spinal problems of different patients to match the patient's pathological condition of height disharmony caused by scoliosis.

[0063] 2. By compensating for the angle difference, patients can complete rehabilitation training more comfortably, thereby improving the quality of training.

[0064] 3. Allow patients to find the best sitting posture during rehabilitation training, improve the status feedback of various parts of the body, and thus enhance the training effect.

[0065] This design has the advantages of low cost, simple structure, and good adaptability, and can provide effective rehabilitation training support for a wider range of scoliosis patients. Obviously, the embodiments described are only part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this utility model.
