[0042] Embodiment 1

[0043] like Figure 1 As shown, the rotation adjustment mechanism provided by the embodiment of the present invention includes: a first locking member 100, a second locking member 200, a rotating disk 300 and a base 400; the rotating disk 300 is rotatably connected to the base 400; the first locking member 100 and the second locking member 200 both have a locked state and an unlocked state, in which the rotating disk 300 is locked to the base 400, and in the unlocked state the rotating disk 300 is unlocked; the first locking member 100 is linked with the second locking member 200 to synchronously switch between the locked state and the unlocked state.

[0044] Specifically, in the locked state, the first locking member 100 and the second locking member 200 work together to lock the rotating disk 300, which can improve the stability of the rotating disk 300 when it is locked. The first locking member 100 and the second locking member 200 are linked to achieve locking or unlocking through synchronous operation.

[0045] In the embodiment of the present invention, the first locking member 100 and the second locking member 200 are spaced apart from each other, and the first locking member 100 and the second locking member 200 are movably connected to the rotating disk 300 , respectively.

[0046] In some embodiments, one of the rotating disk 300 and the base 400 is connected to the first locking member 100 and the second locking member 200, and the first locking member 100 and the second locking member 200 both include a locking pin, the pin shaft is slidably inserted in one of the rotating disk 300 and the base 400, and the other of the rotating disk 300 and the base 400 is provided with a pin hole adapted to the locking pin, and the pin hole is spaced apart from the rotation axis of the rotating disk 300. The first locking member 100 is connected to the second locking member 200, and from the locked state to the unlocked state, the two pin shafts are simultaneously pulled out of the pin hole, so that the rotating disk 300 can rotate freely; from the unlocked state to the locked state, the two pin shafts are inserted into the two pin holes one by one, so that the rotating disk 300 is locked.

[0047] In this embodiment, the first locking member 100 and the second locking member 200 are respectively pivotally connected to the rotating disk 300, and the base 400 is provided with locking parts respectively matched with the first locking member 100 and the second locking member 200. The locking parts can be slots or protrusions, etc. When the first locking member 100 and the second locking member 200 are respectively matched with the locking parts, the rotating disk 300 is locked; when the first locking member 100 and the second locking member 200 are respectively swung to disengage from the locking parts, the rotating disk 300 can rotate freely.

[0048] Furthermore, the first locking member 100 includes a first locking hook, and the second locking member 200 includes a second locking hook, and the first locking hook and the second locking hook are respectively pivoted to the rotating disk 300; the first locking member 401 and the second locking member 402 are connected to the base 400, and the first locking member 401 and the second locking member 402 are arranged at intervals; the first locking hook and the second locking hook are respectively adapted to the first locking member 401 and the second locking member 402.

[0049] Specifically, the first locking member 401 and the second locking member 402 both include a rod connected to the base 400; relative to the rotation axis of the rotating disk 300, the central angle of the first locking member 401 and the second locking member 402 is 180 degrees. From the state where the first locking hook cooperates with the first locking member 401 and the second locking hook cooperates with the second locking member 402, it is switched to the state where the first locking hook cooperates with the second locking member 402 and the second locking hook cooperates with the first locking member 401. That is: every time the rotating disk 300 rotates 180 degrees, it can reach another locking position from one locking position, so that the first locking member 100 and the second locking member 200 are switched from the unlocked state to the locked state.

[0050] In some embodiments, a plurality of the first locking members 401 and the second locking members 402 are provided, and the first locking members 401 and the second locking members 402 are arranged one by one at intervals around the rotation axis of the rotating disk 300. When the rotating disk 300 rotates around the rotation axis, the first locking hook is matched with one of the first locking member 401 and the second locking member 402, and the second locking hook is matched with the other of the first locking member 401 and the second locking member 402, so that the rotating disk 300 can be locked.

[0051] like Figure 1 , Figure 4 and Figure 5 As shown, the openings of the first locking hook and the second locking hook are facing opposite directions; in the locked state, the first locking hook is engaged on the side of the first locking piece 401 facing the second locking piece 402, and the second locking hook is engaged on the side of the second locking piece 402 facing the first locking piece 401; from the locked state to the unlocked state, the first locking hook and the second locking hook are swung inward respectively.

[0052] In the locked state, the first lock hook and the second lock hook are respectively in contact with the inner side of the first locking member 401 and the second locking member 402, so that the first lock hook and the second lock hook are respectively firmly matched with the base 400 to improve the stability of the rotating disk 300 in the locked state. From the locked state to the unlocked state, the first lock hook and the second lock hook are respectively swung inward, which can reduce the space occupied by the first lock hook and the second lock hook in the radial direction of the rotating disk 300 in the unlocked state. Compared with the first lock hook and the second lock hook swinging outward to achieve unlocking, the size space required for arranging the first lock hook and the second lock hook can be reduced, thereby making the structure of the rotation adjustment mechanism more compact.

[0053] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, a release member 500 is movably connected to the rotating disk 300; the release member 500 has a first position and a second position; when the release member 500 is in the first position, the first locking member 100 and the second locking member 200 are both in a locked state; in the second position, the first locking member 100 and the second locking member 200 are both in an unlocked state.

[0054] In some embodiments, both the first locking member 100 and the second locking member 200 use locking pins, and the release member 500 connects the first locking member 100 and the second locking member 200. By operating the release member 500, the two locking pins can be inserted and removed at the same time, thereby achieving synchronous unlocking or locking.

[0055] In this embodiment, the first locking member 100 includes a first locking hook, and the second locking member 200 includes a second locking hook. The first locking hook and the second locking hook are respectively linked to the release member 500. The release member 500 can simultaneously drive the first locking hook and the second locking hook to swing, thereby achieving synchronous unlocking or locking.

[0056] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first lock hook is provided with a first slot hole 110, and the second lock hook is provided with a second slot hole 210; the release member 500 is provided with a first release portion 501 and a second release portion 502, the first release portion 501 is inserted in the first slot hole 110, and the second release portion 502 is inserted in the second slot hole 210; the release member 500 moves between the first station and the second station, and causes the first release portion 501 to slide along the first slot hole 110, and the second release portion 502 to slide along the second slot hole 210.

[0057] Specifically, the release member 500 is slidably connected to the rotating disk 300, and the sliding direction of the release member 500 forms an angle with the rotation axis of the rotating disk 300, and the angle can be configured to be 60 degrees, 70 degrees, 90 degrees or 100 degrees. When the release member 500 moves between the first station and the second station, the first release portion 501 slides along the first slot 110, and the second release portion 502 slides along the second slot 210, and the first locking member 100 is driven to swing through the first release portion 501, and the second locking member 200 is driven to swing through the second release portion 502.

[0058] In one embodiment, the first lock hook is provided with a first shaft hole, and the first hinge shaft connected to the rotating disk 300 is inserted in the first shaft hole, so that the first lock hook is pivotally connected to the rotating disk 300. The second lock hook is provided with a second shaft hole, and the second hinge shaft connected to the rotating disk 300 is inserted in the second shaft hole, so that the second lock hook is pivotally connected to the rotating disk 300. The first shaft hole is located between the first slot hole 110 and the groove of the first lock hook, and the second slot hole 210 is located between the second shaft hole and the groove of the second lock hook. When the release member 500 slides relative to the rotating disk 300, the first release portion 501 drives the first lock hook to swing, and the second release portion 502 drives the second lock hook to swing, and the swing direction of the first lock hook is opposite to the swing direction of the second lock hook.

[0059] Furthermore, the first slot hole 110 includes: a first limiting portion 111 and a first sliding groove portion 112 connected to the first limiting portion 111; the second slot hole 210 includes: a second limiting portion 211 and a second sliding groove portion 212 connected to the second limiting portion 211; when the release member 500 is in the first position, the first release portion 501 is matched with the first limiting portion 111, and the second release portion 502 is matched with the second limiting portion 211; when the release member 500 is in the second position, the first release portion 501 is matched with the first sliding groove portion 112, and the second release portion 502 is matched with the second sliding groove portion 212.

[0060] In some embodiments, the first limiting portion 111 and the first sliding groove portion 112 extend in the same direction, and the width dimension of the first limiting portion 111 is smaller than the width dimension of the first sliding groove portion 112. When the first unlocking portion 501 slides along the first sliding groove portion 112, the first sliding groove portion 112 plays a guiding role, and it should be avoided that the first unlocking portion 501 is stuck due to the small width dimension of the first sliding groove portion 112. In the locked state, the unlocking member 500 is in the second position, and the first unlocking portion 501 slides to the first limiting portion 111. The first limiting portion 111 can clamp the first unlocking portion 501, thereby ensuring that the first unlocking portion 501 is not loose, thereby improving the stability of the rotation adjustment mechanism in the locked state. Similarly, the second limiting portion 211 and the second sliding groove portion 212 extend in the same direction, and the width dimension of the second limiting portion 211 is smaller than the width dimension of the second sliding groove portion 212. When the second release portion 502 slides along the second slide groove portion 212, the second slide groove portion 212 plays a guiding role, and the second release portion 502 should be prevented from getting stuck due to the small width of the second slide groove portion 212. When the release member 500 is in the second position, the second release portion 502 slides to the second limit portion 211, and the second limit portion 211 can clamp the second release portion 502, thereby ensuring that the second release portion 502 is not loose, so as to improve the stability of the rotation adjustment mechanism in the locked state.

[0061] In this embodiment, the extension direction of the first limit portion 111 and the extension direction of the first slide groove portion 112 form an angle, and the extension direction of the second limit portion 211 and the extension direction of the second slide groove portion 212 form an angle. The angle between the extension direction of the first limit portion 111 and the extension direction of the first slide groove portion 112 can be configured as 90 degrees, and the angle between the extension direction of the second limit portion 211 and the extension direction of the second slide groove portion 212 can be configured as 90 degrees.

[0062] Specifically, when the release member 500 slides relative to the rotating disk 300, the first release portion 501 slides along the first slide groove portion 112, and the second release portion 502 slides along the second slide groove portion 212. In the locked state, the first release portion 501 is matched with the first limiting portion 111, and the second release portion 502 is matched with the second limiting portion 211. The first limiting portion 111 can prevent the first release portion 501 from loosening and entering the first slide groove portion 112, and the second limiting portion 211 can prevent the second release portion 502 from loosening and entering the second slide groove portion 212, thereby improving the stability of the rotation adjustment mechanism in the locked state. It should be noted that from the second station to the first station, the release member 500 slides in the first direction. The first limiting portion 111 extends along the first direction from one end connected to the first slide groove portion 112 to one end away from the first slide groove portion 112; the second limiting portion 211 extends along the first direction from one end connected to the second slide groove portion 212 to one end away from the second slide groove portion 212. When the release member 500 slides from the first station to the second station, the release member 500 slides in a direction opposite to the first direction, so that the first release portion 501 can slide from the first limiting portion 111 to the first slide groove portion 112, and the second release portion 502 can slide from the second limiting portion 211 to the second slide groove portion 212, so as to avoid the first release portion 501 and the second release portion 502 from being stuck during the unlocking process.

[0063] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, an elastic element 600 is provided between the release member 500 and the base 400, and the elastic element 600 is configured to make the release member 500 have a tendency to move from the second station to the first station. The elastic element 600 includes a spring, one end of the elastic element 600 is connected to the release member 500, and the other end of the elastic element 600 is connected to the base 400. The release member 500 can be moved from the first station to the second station by manual operation. When the release member 500 is released, the release member 500 moves from the second station to the first station under the action of the elastic element 600. One of the release member 500 and the rotating disk 300 is provided with a slide groove, and the other is provided with a slider adapted to the slide groove. When the release member 500 moves between the first station and the second station, the slider slides along the slide groove, thereby preventing the release member 500 from being deflected or loosened.

[0064] In this embodiment, the elastic element 600 is a tension spring, one end of which is connected to the release member 500, and the other end of which is connected to the base 400. When the release member 500 moves from the first station to the second station, the tension spring elastically deforms and stretches, so that the release member 500 has a tendency to move from the second station to the first station.

[0065] Embodiment 2

[0066] like Figure 1 As shown, the seat provided by the embodiment of the present invention comprises: a seat body and the rotation adjustment mechanism provided by the first embodiment, and the seat body is installed on the rotating disk 300. When the first locking member 100 and the second locking member 200 are both in the unlocked state, the seat body and the rotating disk 300 can rotate synchronously, so as to adjust the orientation of the seat body; when the first locking member 100 and the second locking member 200 are both in the locked state, the rotating disk 300 is locked, so as to fix the orientation of the seat body. The seat provided by this embodiment has the same technical effect as the rotation adjustment mechanism, so it will not be repeated here.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
