[0064] Example:

[0065] See also Figures 1 to 13 The table-type sitting posture corrector in the preferred embodiment of the utility model comprises a table-top portion 1, one end surface of which is provided with a mounting notch 101, and the side wall of the mounting notch 101 extends toward the notch with two engaging portions 102, and the two engaging portions 102 are arranged opposite to each other; a rotating portion 2, the rotating portion 2 is connected with a sitting posture limiting portion 4, and is used to drive the sitting posture limiting portion 4 to adjust its position; the rotating portion 2 is embedded in the mounting notch 101, and the rotating portion 2 is provided with two engaging portions at both ends of the two engaging portions 102. The two engaging parts 102 are rotatably arranged in the two engaging notches 201 respectively; at the same time, the two engaging parts 102 are provided with at least a first engaging groove 103 and a second engaging groove 104 at one end facing the rotating part 2, and the extension directions of the first engaging groove 103 and the second engaging groove 104 are different; a limiting strip 202 matching the first engaging groove 103 or the second engaging groove 104 is also provided in the installation notch 101, and the limiting strip 202 is embedded in the first engaging groove 103 or the second engaging groove 104.

[0066] Specifically, the present application sets a rotating part 2, and uses the form of matching the engaging part 102 with the engaging notch 201 to realize the flipping of the rotating part 2, so as to drive the sitting posture limiting part 4 to stand on the table top part 1 or be stored under the table top part 1, thereby reducing the space occupied by the sitting posture corrector on the desk when not in use. At the same time, the present application sets a first engaging groove 103 and a second engaging groove 104 at the end of the engaging part 102, and sets a limiting strip 202 accordingly, and the limiting strip 202 is matched with the first engaging groove 103 or the second engaging groove 104 respectively, so as to limit the rotating part 2 to different rotation angles, realize the position change of the sitting posture limiting part 4, and ensure the stable limit of the sitting posture limiting part 4 when in use.

[0067] More preferably, if Figure 3 , Figure 4 As shown, in the present application, the locking portion 102 is provided with a first locking groove 103, a second locking groove 104, a third locking groove and other multiple locking grooves at one end facing the rotating portion 2. The above-mentioned multiple locking grooves extend radially along the end face of the locking portion 102. When the rotating portion 2 rotates, the limit strip 202 can be correspondingly inserted into different locking grooves to limit the sitting position limiting portion 4 connected to the rotating portion 2 to different angle positions to meet the different usage requirements of the user.

[0068] Further preferably, the first engaging groove 103 and the second engaging groove 104 are arranged as arc grooves on the end surface of the engaging portion 102 . The arc groove structure facilitates the corresponding engagement or disengagement of the limiting strip 202 into or out of the engaging grooves, thereby facilitating the rotation switching of the rotating portion 2 .

[0069] As an optional embodiment of the utility model, the first engaging groove 103 and the second engaging groove 104 in the present application are cross-arranged, and the two form a cross notch on the end face of the engaging portion 102, and by matching with the limit strip 202, the switching of four angle gears is realized.

[0070] Optionally, in the present application, one end of the locking portion 102 facing the locking groove can be set to a wavy arc structure to increase the damping when the rotating portion 2 rotates, ensuring that the limiting strip 202 is stably locked in the first locking groove 103 or the second locking groove 104.

[0071] Further, as a preferred embodiment of the present invention, Figure 5 , Figure 6As shown, the rotating part 2 in the present application includes a first rotating part 204 and a second rotating part 205 which are arranged in a spliced ​​manner, and the two above-mentioned engaging notches 201 are formed at the connecting end surfaces of the first rotating part 204 and the second rotating part 205; at the same time, the first rotating part 204 extends a limiting strip 202 toward the second rotating part 205, and the second rotating part 205 extends an abutting part 203 toward the first rotating part 204, and the abutting part 203 is arranged at one end of the limiting strip 202 away from the engaging part 102, and the abutting part 203 is arranged in close contact with the limiting strip 202. Since the limiting strip 202 and other structures need to be arranged inside the rotating part 2, in order to facilitate the overall manufacturing of the rotating part 2, the rotating part 2 is arranged in a spliced ​​form of the first rotating part 204 and the second rotating part 205, so as to facilitate the assembly of the rotating part 2. At the same time, in order to increase the degree of close contact between the limiting strip 202 and the engaging groove, it is prevented that the rotating part 2 is driven to rotate when the user leans on the sitting position limiting part 4. The present application corresponds to setting an abutment portion 203 on the side of the limiting strip 202 away from the locking portion 102, and the abutment portion 203 strengthens the limiting ability of the limiting strip 202, so that the limiting strip 202 is conveniently locked into the locking groove.

[0072] It is worth noting that due to assembly accuracy issues, when there is a certain gap between the abutment portion 203 and the limiting strip 202 in the present application, it should also be included in the protection scope of the present application as long as it does not affect the supporting effect of the abutment portion 203 on the limiting strip 202.

[0073] Further preferably, in the present application, the first rotating part 204 is further provided with a limiting groove 206 and / or a limiting rod 207 toward the second rotating part 205, and the second rotating part 205 is correspondingly provided with a limiting rod 207 and / or a limiting groove 206.

Preferably, the first rotating part 204 and the second rotating part 205 in the present application are both semicircular structures, which are hollow inside, and the two are assembled to form a circular cylindrical rotating part 2.

[0074] As a preferred embodiment of the utility model, the side of the mounting notch 101 in the present application facing the rotating part 2 is an arc-shaped groove surface structure, and matches the above-mentioned rotating part 2 in a circular cylindrical shape. When the rotating part 2 is engaged in the mounting notch 101, the rotating part 2 is correspondingly attached to the surface of the mounting notch 101. Through the matching design of the two, the connection between the table top part 1 and the rotating part 2 is smoothly transitioned, avoiding the rotating part 2 from protruding too much from the surface of the table top part 1, and avoiding a large gap between the rotating part 2 and the mounting notch 101 of the table top part 1 when the rotating part 2 rotates, resulting in pinching of users or accumulation of dust, debris, etc.

[0075] Further preferably, a linear protrusion is also provided on the side wall of the installation notch 101 facing the rotating part 2, and a linear guide groove is correspondingly provided on the outer periphery of the rotating part 2, and the linear protrusion is embedded in the linear guide groove. The linear guide groove is mainly used to assist the rotation of the rotating part 2. Through the limiting effect of the linear protrusion and the linear guide groove, the rotating part 2 is prevented from tilting to both sides when rotating, so as to avoid unhealthy wear of the sitting posture corrector caused by long-term tilting and rotation, and eventually cause the rotating part 2 to separate from the table top part 1. Correspondingly, in the present application, a linear guide groove is provided on the installation notch 101, and a linear protrusion is correspondingly provided on the rotating part 2, which is also an optional form in the present application.

When the first telescopic member 301 and the second telescopic member 302 slide relative to each other, the overall length of the telescopic part 3 changes, and the position of the sitting position limiting part 4 is adjusted. When the first retaining ring 303 and the second retaining ring 304 touch each other, the telescopic part 3 is telescoped to the maximum length to avoid the first telescopic member 301 from being separated from the second telescopic member 302. It is worth noting that the above-mentioned first retaining ring 303 is fixedly connected to the second telescopic member 302, and the second retaining ring 304 is fixedly connected to the first telescopic member 301 to avoid the retaining ring from being separated from the telescopic member. Optionally, in order to increase the telescopic length of the telescopic part 3 in the present application, the present application may also include a first telescopic member 301, a second telescopic member 302, a third telescopic member, etc., and the length of the telescopic part 3 can be changed by setting it to a multi-stage telescopic form.
