[0002] In recent years, with the rapid development of electronic technology, the application scenarios of various display devices have continued to expand. Taking cash registers as an example, as an important piece of equipment in the commercial field, they have been widely used in convenience stores, supermarkets, shopping malls, and many other places. However, due to the differences in equipment placement and operating habits in different application scenarios, it is often necessary to adjust the display orientation of the cash register screen (such as landscape or portrait mode) to adapt to actual usage needs.

[0003] Currently, most cash register displays have cumbersome rotation adjustment methods, usually requiring manual disassembly or physical adjustment with the help of tools, which causes inconvenience to users.

[0037] In the preferred embodiment of the above-described rotating mechanism, when the number of the first locking structures is at least two, the at least two first locking structures are arranged at intervals on the joint assembly along the rotation direction of the rotating assembly; and

[0038] When the second locking structure is in the first position, the second locking structure engages with one of the first locking structures to lock and restrict the rotation of the rotating component; when the second locking structure is in the second position, the second locking structure releases from the currently engaged first locking structure so that the rotating component can rotate and form a locking engagement with the other first locking structure.

[0039] In a preferred embodiment of the aforementioned rotating mechanism, the connector includes a connector body and a connecting shaft disposed on the connector body, wherein the rotating component is rotatably disposed on the connecting shaft; and

[0040] The locking ring is disposed at the end of the connecting shaft away from the connector body; or, the locking ring is disposed on the connector body, and a third limiting member is disposed at the end of the connecting shaft away from the connector body; or, the locking ring is disposed on the connecting shaft near the connector body, and a third limiting member is disposed at the end of the connecting shaft away from the connector body, and the rotating assembly is disposed on the connecting shaft between the third limiting member and the locking ring.

[0045] This application also provides a display device, which includes the rotating mechanism described in the above preferred solution, or the bracket described in the above preferred solution.

[0046] Those skilled in the art will understand that the rotating mechanism of this utility model, by providing a first locking structure on the joint assembly and a second locking structure on the locking assembly, and by configuring the second locking structure to move between a first position and a second position, allows the second locking structure to engage with the first locking structure when in the first position, thereby restricting the rotation of the rotating assembly and fixing the display orientation of the screen. When the second locking structure is in the second position, it releases from the first locking structure, allowing the rotating assembly to drive the display screen to rotate freely, thus enabling the display screen to be in different display orientations and achieving multi-angle adjustment. This application allows for adjustment of the display orientation of the screen through simple displacement operations, solving the problem of inconvenient screen rotation adjustment in the prior art, and greatly improving the convenience and user experience of user adjustment.

[0047] Furthermore, by movably mounting the locking lever on the rotating assembly, it is helpful for the locking lever to drive the second locking structure to move between the first and second positions.

[0048] Furthermore, an oblong hole is used as the first connecting structure, and a connecting rod is used as the second connecting structure, or a connecting rod is used as the first connecting structure, and an oblong hole is used as the second connecting structure. The oblong hole is extended radially along the rotating component, so that the locking rod can drive the second locking structure to move radially, thereby realizing the locking or unlocking of the rotating component.

[0049] Furthermore, when the first connecting structure is the oblong hole and the second connecting structure is the connecting rod, by providing a handle on the connecting rod or the locking rod, it is helpful for the locking rod to drive the second locking structure to move radially when the connecting rod moves along the length direction of the oblong hole, thereby achieving the locking or unlocking of the rotating component. Additionally, when the first connecting structure is the connecting rod and the second connecting structure is the oblong hole, by providing a handle on the locking rod, it is helpful for the locking rod to drive the second locking structure to move radially relative to the connecting rod, thereby achieving the locking or unlocking of the rotating component.

[0050] Furthermore, by setting the lock frame on the rotating assembly and providing a channel on the lock frame for the lock rod to pass through, the lock rod can move smoothly radially within the channel, thereby reliably driving the second locking structure to move between the first and second positions.

[0051] Furthermore, by setting an elastic element, the locking rod stores elastic potential energy when the second locking structure is in the first position. When the external force is removed, this elastic potential energy helps the locking rod drive the second locking structure to return from the second position to the first position.

[0052] Furthermore, a connecting hole is used as the first connecting structure, and a connecting rod is used as the second connecting structure. The axial direction of the connecting hole is parallel to the rotation axis of the rotating component, so that the locking rod moves along the axial direction of the rotating component under the action of the connecting rod, thereby driving the second locking structure to lock or unlock the rotating component. Additionally, a connecting rod is used as the first connecting structure, and a connecting hole is used as the second connecting structure. The length direction of the connecting rod is parallel to the rotation axis of the rotating component, so that the locking rod can move along the axis of the rotating component, thereby driving the second locking structure to lock or unlock the rotating component.

[0053] Furthermore, by providing a telescopic component between the locking rod and the rotating assembly, it is possible to ensure that the locking rod moves smoothly along the axial direction of the rotating assembly, thereby reliably driving the second locking structure to move between the first and second positions.

[0054] Furthermore, by setting the first locking structure as a latch and the second locking structure as a keyhole, or by setting the first locking structure as a keyhole and the second locking structure as a keyhole, locking between the first locking structure and the second locking structure can be achieved, thereby improving the practicality of this application.

[0055] Furthermore, by setting a stop on the connector assembly, the first locking structure and the second locking structure are aligned, which facilitates locking between the first locking structure and the second locking structure.

[0056] Furthermore, by setting the number of first locking structures to at least two and arranging these first locking structures at intervals on the connector assembly along the rotation direction of the rotating assembly, it is helpful for the second locking structure to lock and engage with the first locking structures at different positions, thereby enabling the display direction of the display screen to be fixed at multiple angles.

[0057] Furthermore, by setting a locking ring or limiting element at the end of the connecting shaft away from the connector body, axial displacement of the rotating component is achieved, ensuring rotational stability. Attached Figure Description

[0076] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0077] It should be noted that in the description of this application, the terms "upper", "lower", "inner", "bottom", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0078] Furthermore, it should be noted that, in the description of this application, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0079] Reference Figure 1-15 The present application will now describe the display device.

[0080] like Figure 1-2 As shown, the display device of this application includes a bracket assembly 100 and a display screen 200. The bracket assembly 100 includes a bracket 2 and a rotating mechanism 1 disposed on the bracket 2. The rotating mechanism 1 is connected to the display screen 200, so that the display screen 200 can rotate under the action of the rotating mechanism 1, thereby solving the problem of inconvenient rotation adjustment of the display screen 200.

[0081] See next Figure 3-15The rotating mechanism 1 includes a connector assembly 11, a rotating assembly 12, and a locking assembly 13. The connector assembly 11 includes a connector 111 and a locking ring 112. The connector 111 includes a connector body 1111 and a connecting shaft 1112 mounted on the connector body 1111. The connector body 1111 has an installation position, which is a mounting hole, through which the connector body 1111 connects to the bracket 2. The rotating assembly 12 is sleeved on the connecting shaft 1112, and a locking ring 112 is provided at the end of the connecting shaft 1112 away from the connector body 1111, thereby restricting the axial displacement of the rotating assembly 12 and preventing the rotating assembly 12 from detaching from the connecting shaft 1112 during rotation.

[0082] In an exemplary embodiment, to ensure smooth rotation of the rotating assembly 12, an axial clearance is provided between the locking ring 112 and the rotating assembly 12, meaning that the axial dimension of the connecting shaft 1112 is greater than the dimension of the rotating assembly 12 in the axial direction of the connecting shaft 1112. Furthermore, to facilitate the assembly of the rotating assembly 12 and the connector assembly 11, the locking ring 112 can be fixed to the end face of the connecting shaft 1112 by fasteners, specifically as follows... Figure 4 As shown, the locking ring 112 is mounted on the connecting shaft 1112 by bolts.

[0083] In exemplary embodiments, the location of the locking ring 112 is not fixed and can be adjusted as needed by those skilled in the art. For example, the locking ring 112 can also be located near the connector body 1111 or the connecting shaft 1112. In this case, a third limiting member can be provided at the end of the connecting shaft 1112 away from the connector body 1111 to limit the axial position of the rotating component 12. The third limiting member can be a limiting plate or a limiting rod, etc. When the locking ring 112 is located near the connector body 1111, the locking ring 112 is located near the connector body 1111, and the rotating component 12 is provided on the connecting shaft 1112 between the third limiting member and the locking ring 112. Furthermore, the shape of the locking ring 112 is not limited in this application and can be adjusted as needed by those skilled in the art. For example, the locking ring 112 can also be circular, semi-circular, or elliptical, etc.

[0084] See next Figure 3-14 Two first locking structures are provided on the outer peripheral surface of the locking ring 112. The first locking structure is a first locking hole 1121. The two first locking holes 1121 are arranged at intervals along the rotation direction of the rotating component 12, and the angle between the two first locking holes 1121 and the rotation axis of the rotating component 12 is 90°, so that the display screen 200 can switch between portrait mode and landscape mode.

[0085] In the exemplary embodiments, the form and position of the first locking structure are not fixed in this application, and those skilled in the art can adjust them as needed. For example, the first locking structure can also be a second locking tongue 1122, such as... Figure 8 As shown; and / or, the first locking structure can also be disposed on the end face of the locking ring 112, as shown. Figure 15 As shown. Furthermore, the specific angle between two adjacent first locking structures and the rotation axis of the rotating assembly 12 is not fixed in this application; those skilled in the art can adjust it as needed. For example, the angle can also be 60°, 120°, or 180°, etc.

[0086] In the exemplary embodiments, the number of first locking structures provided in this application is not fixed, and those skilled in the art can adjust it as needed. For example, the number of first locking structures can also be 1, 3, or other numbers.

[0087] See Figure 4 The rotating assembly 12 includes a rotating flange 121 and a bearing 122. The rotating flange 121 has a first side and a second side arranged opposite to each other. The first side is close to the locking ring 112 and connected to the display screen 200, and the second side is close to the connector body 1111. The rotating flange 121 is rotatably mounted on the connecting shaft 1112 via the bearing 122, so that the rotating flange 121 can drive the display screen 200 to rotate around the connecting shaft 1112, enabling the display screen to be adjusted at multiple angles.

[0088] It should be noted that when the locking ring 112 is located near the connector body 1111 of the connecting body or the connecting shaft 1112, and a third limiting member is provided at the end of the connecting shaft 1112 away from the connector body 1111, the third limiting member is close to the first surface, and the connecting body and the connecting shaft 1112 are close to the second surface.

[0089] See next Figure 3-15 The locking component 13 of this application will be described below. The second locking structure on the locking component 13 can have two operating modes: one is that the second locking structure moves radially along the rotation direction of the rotating component 12, that is, the line connecting the first position and the second position is in the same radial direction as the rotation direction of the rotating component 12; the other is that the second locking structure moves along the axial direction of the rotating component 12, that is, the line connecting the first position and the second position is parallel to the rotation axis of the rotating component 12.

[0090] It should be noted that when the second locking structure moves radially along the rotation direction of the rotating assembly 12, the second locking structure is disposed on the outer peripheral surface of the locking ring 112. When the second locking structure moves along the axial direction of the rotating assembly 12, the second locking structure can be disposed either on the outer peripheral surface of the locking ring 112 or on the end face of the locking ring 112.

[0091] like Figure 3-8 As shown, the explanation focuses on the radial movement of the second locking structure along the rotation direction of the rotating assembly 12.

[0092] See Figure 3-8 The rotating flange 121 is provided with a first connecting structure and a locking assembly 13. The first connecting structure is an oblong hole 1211, the length of which is radially parallel to the rotation direction of the rotating assembly 12. The locking assembly 13 is located on the first surface, with a second connecting structure at one end and a second locking structure at the other end. The second connecting structure is a connecting rod 136, and the second locking structure is a first locking tongue 132. The connecting rod 136 is inserted into the oblong hole 1211 and connected to a handle 137 located on the second surface. The handle 137 serves two purposes: firstly, it restricts the axial displacement of the locking assembly 13, preventing the locking element from dislodging from the connecting rod 136; secondly, it facilitates the application of force to the connecting rod 136, allowing it to move along the length of the oblong hole 1211. This, in turn, causes the first locking tongue 132 to move radially between a first position and a second position along the rotation direction of the rotating assembly 12, thereby achieving locking or unlocking with the first locking hole 1121.

[0093] When the rotating flange 121 is connected to the display screen 200, the display screen 200 can be directly installed on the first side of the rotating flange 121, or the rotating flange 121 can be integrated into the display screen 200. In this case, the display screen 200 is provided with a hole on the side near the connector body 1111 for the handle 137 to pass through and move.

[0094] In the exemplary embodiment, the position of the handle 137 is not fixed and can be adjusted as needed by those skilled in the art. For example, the handle 137 can also be positioned on the locking bar corresponding to the waist-shaped hole 1211, and the handle 137 passes through the waist-shaped hole 1211 and is located on the second side. In this case, to prevent the locking bar from coming out of the waist-shaped hole 1211, a limiting member can be provided on the end face of the connecting rod 136.

[0095] In the exemplary embodiments, the configuration of the first and second connecting structures is not fixed and can be adjusted by those skilled in the art according to the configuration requirements. For example, the first connecting structure can also be a connecting rod 136, and the second connecting structure can be a waist-shaped hole 1211. The length direction of the waist-shaped hole 1211 is radial to the rotation direction of the rotating flange 121, which also facilitates the locking rod 131 driving the first locking tongue 132 to move relative to the connecting rod 136 between the first and second positions along the length direction of the waist-shaped hole 1211. In this case, both the connecting rod 136 and the locking assembly 13 are located on the second surface. It should be noted that, in order to prevent the locking rod 131 from detaching from the connecting rod 136, a limiting plate can be provided at the end of the connecting rod 136 away from the rotating flange 121. At the same time, in order to facilitate applying force to the locking rod 131 and facilitate the locking rod 131 driving the first locking tongue 132 to move between the first and second positions, a handle 137 can be provided on the locking rod 131.

[0096] In the exemplary embodiments, the configuration of the first and second locking structures in this application is not fixed, and those skilled in the art can adjust it according to configuration needs. For example, the first locking structure can be a second locking tongue 1122, and the second locking structure can be a second locking hole 1311 that cooperates with the second locking tongue 1122, such as... Figure 8 As shown. When there is only one first locking structure, although the orientation of the display screen 200 can be adjusted, this first locking structure can only lock with the second locking structure on the locking assembly 13, thus fixing the display screen 200 in only one direction. However, when there are two or more first locking structures, these structures are arranged at intervals along the rotation direction of the rotating assembly 12. The angle between two adjacent first locking structures relative to the rotation axis of the rotating assembly 12 can be 60°, 90°, 120°, or 180°, etc. Because there are a relatively large number of first locking structures, the display screen 200 can be fixed at multiple angles.

[0097] Referring then to 3-4, the locking assembly 13 includes a locking rod 131, a locking frame 133, a connecting rod 136, a second locking structure, and an elastic element. The locking frame 133 includes a connecting plate 1331, a first limiting member, and a connecting block 1332. The connecting block 1332 and the first limiting member are located on the same side of the connecting plate 1331. The first limiting member is the limiting plate 1333. The connecting block 1332 and the first limiting plate 1333 are arranged sequentially in a direction away from the rotation axis of the rotating assembly 12. A channel is provided on the connecting block 1332, into which the locking rod 131 is inserted. One end of the locking rod 131 extends out of the channel and passes through the limiting plate 1333, and the connecting rod 136 is located at this end. The other end of the locking rod 131 can extend out of the channel, and the second locking structure is located at this end. The second locking structure is a first locking tongue 132, and the first locking tongue 132 can move in and out of the channel under the action of the locking rod 131. Both the locking rod 131 and the channel extend radially along the rotation direction of the rotating flange 121. The locking rod 131 is also provided with a second limiting member and a sleeved elastic member. The second limiting member is a limiting rod 134, and the elastic member is a spring 135. The limiting rod 134 and the spring 135 are both located between the limiting plate 1333 and the connecting block 1332, and the two ends of the spring 135 abut against the limiting rod 134 and the limiting plate 1333, respectively. When the connecting rod 136 drives the locking rod 131 to move along the length direction of the oblong hole 1211, the first locking tongue 132 on the locking rod 131 can move between a first position and a second position. When the first locking tongue 132 is in the first position, the first locking tongue 132 extends out of the channel and locks into a first locking hole 1121, thereby restricting the rotation of the rotating flange 121 and fixing the display screen 200 on the rotating flange 121. When the first locking tongue 132 is in the second position, the spring 135 is compressed, and the first locking tongue 132 enters the channel. At this time, the first locking tongue 132 is unlocked from the first locking hole 1121, and the rotating flange 121 can rotate, which helps to adjust the display direction of the display screen 200. When the first locking tongue 132 corresponds to the position of another first locking hole 1121, the external force applied to the handle 137 is removed, so that the first locking tongue 132 can move from the second position to the first position under the action of the spring 135 and lock into the first locking hole 1121 at that position, thereby fixing the display direction of the display screen 200.

[0098] In exemplary embodiments, the specific shape of the lock frame 133 is not fixed and can be adjusted by those skilled in the art as needed. For example, the lock frame 133 may only include a connecting block 1332 and an elastic member. In this case, the connecting block 1332 can be used as a first limiting member, or a first limiting member can be provided in the channel of the connecting block 1332. The first limiting member and the second limiting member on the lock rod 131 are arranged sequentially in a direction away from the rotation axis of the rotating assembly 12, and the elastic member sleeved on the lock rod 131 abuts against the connecting block 1332 and the second limiting member, respectively. Alternatively, the lock frame 133 may only include a connecting block 1332, which has a channel for the lock rod 131 to enter and exit. Both of these lock frame 133 structures can achieve locking or unlocking with the first locking structure. In other preferred embodiments, the setting of the lock frame 133 is not mandatory and can be selected by those skilled in the art as needed. Without the lock frame 133, the cross-sectional shape of the connecting rod 136 can be set to rectangular. The connecting rod 136 can also drive the lock rod 131 to move smoothly along the length direction of the waist-shaped hole 1211, thereby ensuring the stability of the first locking tongue 132 on the lock rod 131 moving between the first position and the second position.

[0099] In exemplary embodiments, this application does not limit the connection method between the second limiting member and the locking rod 131, as long as the second limiting member is disposed on the locking rod 131 and can compress the elastic block with the first limiting member on the locking frame 133. Figure 3-4 As shown, a connecting hole can be provided on the locking rod 131, and the second limiting member is inserted into the connecting hole. This method also facilitates the assembly of the locking assembly 13.

[0100] See next Figure 3-8 The connecting plate 1331 on the locking frame 133 is located on the second side of the rotating flange 121 and completely covers the mounting hole 1212 on the rotating flange 121. It is fixed to the locking frame 133 by bolts. The connecting block 1332 and the first limiting member on the connecting plate 1331 are both located on the side of the connecting plate 1331 located on the first side and extend out of the mounting hole 1212, so that the connecting block 1332 and the limiting plate are both located on the first side, which helps the rotating assembly 12 and the joint assembly 11 to lock or unlock.

[0101] In the exemplary embodiment, and in other preferred embodiments, the mounting holes 1212 on the rotary flange 121 are not mandatory, and those skilled in the art can choose as needed. Without the mounting holes 1212, the connecting plate 1331 is directly bolted to the first surface of the rotary flange 121. It should also be noted that, with the connecting plate 1331 in place, the connecting block 1332 can be directly fixed to the rotary flange.

[0102] See next Figure 3-8 The two first locking holes 1121 on the locking ring 112 divide the outer circumference of the locking ring 112 into two parts. The angle between the first part and the rotation axis of the rotating assembly 12 is 90°, and the angle between the second part and the rotation axis of the rotating assembly 12 is 270°. The second part is provided with a stop 1123, which covers the entire second part, making the outer diameter of the second part larger than the outer diameter of the first part. The first locking tongue 132 on the locking assembly 13 abuts against the stop 1123 during rotation, and the first locking tongue 132 is aligned with the first locking hole 1121. At this time, the external force on the locking rod 131 is removed, and the first locking tongue 132 can lock with the first locking hole 1121, thereby achieving the purpose of fixing the display screen 200.

[0103] In an exemplary embodiment, the first locking structure and the second locking structure are aligned in a manner that can be either the first locking tongue 132 abutting against the stop member 1123, or the locking frame 133 on the locking assembly 13, as long as the stop member 1123 can abut against the locking assembly 13. Furthermore, in an exemplary embodiment, the stop member 1123 can be a stop block.

[0104] In the exemplary embodiments, the arrangement of the stop member 1123 is not fixed and can be adjusted as needed by those skilled in the art. For example, there can be two stop members 1123. That is, the stop members 1123 do not completely cover the entire second part, but the two stop members 1123 correspond to the two first locking holes 1121 respectively, and are respectively set on the edge of the second part near the first locking hole 1121. This also facilitates the correspondence between the first locking structure and the second locking structure, and facilitates the locking of the first locking tongue 132 and the first locking hole 1121. It should be noted that when there is one first locking hole 1121, there can be one stop member 1123. The stop member 1123 can be set on the outer peripheral surface of the locking ring 112 near the first locking hole 1121. In this case, the distance between the outer peripheral surface of the stop member 1123 and the rotation axis of the rotating flange 121 can be greater than the distance between the first position and the rotation axis of the rotating flange 121. When the number of first locking holes 1121 is three or more, the same number of stop members 1123 as the number of first locking holes 1121 can be set. Each stop member 1123 is set on the outer peripheral surface of the locking ring 112 near the first locking hole 1121. In order to avoid the stop member 1123 affecting the rotation of the rotating assembly 12 and the locking assembly 13, the distance between the outer peripheral surface of the stop member 1123 and the rotation axis of the rotating flange 121 is less than the distance between the first position and the rotation axis of the rotating flange 121, but greater than the distance between the outer peripheral surface of the locking ring 112 and the rotation axis of the rotating flange 121. The first lock hole 1121 and the stop 1123 are described in three parts each. The three first lock holes 1121 and the stop 1123 are labeled counterclockwise as first lock hole one, second lock hole two, third lock hole three, stop one, stop two, and stop three. Stop one is located on the outer circumference of the lock ring 112 at a counterclockwise position in first lock hole one; stop two is located on the outer circumference of the lock ring 112 at a clockwise position in first lock hole two; and stop three is located on the outer circumference of the lock ring 112 at a clockwise position in first lock hole three. When the first lock... When the first latch 132 needs to be locked with the first lock hole three, and the first latch 132 is locked with the first latch 132 at this time, after applying force to move the first latch 132 from the second position to the first position, rotate the rotating flange 121. After the locking assembly can pass the second stop, the external force applied to the handle 137 can be reduced, so that the first latch 132 abuts against the outer circumferential surface of the lock ring 112. When the first latch 132 abuts against the third stop, the first latch 132 is aligned with the third lock hole three. The external force is removed, so that the first latch 132 is locked with the third lock hole three.It should be noted that when the first locking structure is the second locking tongue 1122 and the second locking structure is the second locking hole 1311, a stop 1123 can also be provided on the outer circumferential surface of the locking ring 112 corresponding to each locking structure according to the number of the first locking structures. The distance between each stop 1123 and the rotation axis of the rotating flange 121 is less than the distance between the first position and the rotation axis of the rotating flange 121.

[0105] Combination Figure 5-7 The rotation method of the rotating mechanism 1 of this application will be described.

[0106] like Figure 5 As shown, the first locking tongue 132 on the locking rod 131 is locked in place with a first locking hole 1121 on the locking ring 112. At this time, the rotating flange 121 cannot rotate. Since the second side of the rotating flange 121 is provided with a display screen 200, the display screen 200 is in a fixed state.

[0107] During unlocking, a force is applied to handle 137 in a direction away from the rotation axis of rotating flange 121, driving connecting rod 136 to move locking rod 131 in a direction away from the rotation axis of rotating flange 121, i.e., towards the second position. When the first locking tongue 132 is in the second position, the first locking tongue 132 disengages from the first locking hole 1121, and the first locking tongue 132 and the first locking hole 1121 are unlocked. Rotating flange 121 can then rotate display screen 200, thereby adjusting the display orientation of display screen 200. Figure 6 This is a schematic diagram of the rotating flange 121 during rotation, at which time the locking rod 131 is positioned between the two first locking holes 1121.

[0108] When the first locking tongue 132 abuts against the stop 1123 at another first locking hole 1121, the display screen 200 rotates to the target position, and the first locking tongue 132 aligns with the first locking hole 1121. At this time, a force is applied in the opposite direction to the handle 137 (a force in the direction of rotation towards the axis of rotation of the rotating flange 121), driving the connecting rod 136 to move the locking rod 131 in the direction of rotation towards the axis of rotation of the rotating flange, that is, in the direction of the first position. Figure 7 As shown, when the first locking tongue 132 is in the first position, the first locking tongue 132 is finally locked to the new first locking hole 1121.

[0109] like Figure 9-15 As shown, the second locking structure is moved along the axial direction of the rotating assembly 12.

[0110] See next Figure 4 , 9-15. The rotating flange 121 is provided with a first connecting structure and a locking assembly 13. The first connecting structure is a connecting hole, the axial direction of which is parallel to the axis of the rotating assembly 12. The locking assembly 13 is located on the first surface, with a second connecting structure at one end and a second locking structure at the other end along the rotation direction of the rotating assembly 12. The second connecting structure is a connecting rod 136, and the second locking structure is a first locking tongue 132. The connecting rod 136 is inserted into the connecting hole and connected to a handle 137 located on the second surface. The handle 137 prevents the connecting rod 136 from coming out of the connecting hole and facilitates the application of force to the connecting rod 136, causing it to move along the axial direction of the connecting hole. This, in turn, drives the first locking tongue 132 to move between a first position and a second position along the axis of the rotating assembly 12, thereby achieving locking or unlocking with the first locking hole 1121.

[0111] In the exemplary embodiments, the configuration of the first and second connecting structures is not fixed and can be adjusted by those skilled in the art according to the configuration requirements. For example, the first connecting structure can also be a connecting rod 136, the length direction of which is parallel to the axis of the rotating assembly 12, and the second connecting structure can be a connecting hole, which also facilitates the locking rod 131 to drive the first locking tongue 132 to move between the first and second positions along the length direction of the connecting rod 136. In this case, both the connecting rod 136 and the locking assembly are located on the second surface. It should be noted that, in order to prevent the locking rod 131 from detaching from the connecting rod 136, a limiting plate can be provided at the end of the connecting rod 136 away from the rotating flange 121. At the same time, in order to facilitate applying force to the locking rod 131 and facilitate the locking rod 131 to drive the first locking tongue 132 to move between the first and second positions, a handle 137 can be provided on the locking rod 131.

[0112] In the exemplary embodiments, the configuration of the first and second locking structures in this application is not fixed, and those skilled in the art can adjust it according to configuration needs. For example, the first locking structure can be a second locking tongue 1122, and the second locking structure can be a second locking hole 1311 that cooperates with the second locking tongue 1122, such as... Figure 14 As shown.

[0113] See next Figure 9-15The locking assembly 13 includes a locking rod 131, a connecting rod 136, a second locking structure, and a telescopic member. The second locking structure is a first locking tongue 132. The locking rod 131 extends radially along the rotation direction of the rotating flange 121, and the first locking tongue 132 is provided at the end of the locking rod 131 near the locking ring 112, while the connecting rod 136 is provided at the end of the locking rod 131 away from the locking ring 112. A telescopic member is provided in the middle of the locking rod 131, and the other end of the telescopic member is connected to the rotating flange 121. When the connecting rod 136 drives the locking rod 131 to move along the axial direction of the connecting hole, the first locking tongue 132 on the locking rod 131 can move between a first position and a second position. When the first locking tongue 132 is in the first position, the locking rod 131 is close to the rotating flange 121, and the length of the telescopic member becomes shorter. At this time, the first locking tongue 132 locks into a first locking hole 1121, thereby restricting the rotation of the rotating flange 121 and thus fixing the display screen 200. When the first locking tongue 132 is in the second position, the locking rod 131 drives the first locking tongue 132 away from the axis of the rotating flange 121. At this time, the length of the telescopic member is relatively long, and the first locking tongue 132 is unlocked from the first locking hole 1121. The rotating flange 121 can rotate, which helps to adjust the display direction of the display screen 200. When the first locking tongue 132 corresponds to the position of another first locking hole 1121, the handle 137 applies force to the connecting rod 136, so that the first locking tongue 132 can move from the second position to the first position and lock into the first locking hole 1121 at that position, thereby fixing the display direction of the display screen 200.

[0114] It should be noted that when the second locking structure is located on the outer circumferential surface of the locking ring 112, the configuration of the first locking structure (lock hole or lock tongue) varies, and the configuration method of the first locking structure also differs. When the first locking structure is the first lock tongue 132, the first lock tongue 132 can be located at the end of the locking rod 131 near the locking ring 112. In this case, the first lock tongue 132 extends radially along the rotation direction of the rotating assembly 12, such as... Figure 8-14 As shown; or the first locking tongue 132 can also be located on the side of the locking rod 131 near the rotating flange 121, in which case the first locking tongue 132 extends along the rotation axis of the rotating assembly 12, as shown. Figure 15 As shown. When the first locking structure is the second lock hole 1311, the second lock hole 1311 penetrates the end face of the lock rod 131 near the lock ring. At this time, the second lock hole 1311 extends radially along the rotation direction of the rotating assembly 12.

[0115] It should also be noted that when the second locking structure is located on the end face of the locking ring 112, the configuration of the first locking structure (lock hole or lock tongue) varies, and the configuration method of the first locking structure also differs. When the first locking structure is the first lock tongue 132, the first lock tongue 132 is located on the side of the locking rod 131 near the rotating flange 121, and in this case, the first lock tongue 132 extends along the rotation axis of the rotating assembly 12. When the first locking structure is the second lock hole 1311, the second lock hole 1311 can penetrate the end face of the locking rod 131 near the locking ring, and in this case, the first lock hole 1311 extends radially along the rotation direction of the rotating assembly 12; or the second lock hole 1311 is a closed hole structure, and in this case, the second lock hole 1311 extends along the axial direction of the rotating assembly 12.

[0116] In exemplary embodiments, this application does not limit the specific form of the telescopic component, as long as it enables the locking rod 131 to move smoothly without affecting the locking of the first and second locking structures. For example, the telescopic component can be a telescopic rod. Alternatively, the telescopic component includes a telescopic rod and an elastic element sleeved on the telescopic rod. Furthermore, in other preferred embodiments, the telescopic component is not mandatory, and those skilled in the art can choose it as needed. Where a telescopic rod is not provided, the cross-sectional shape of the connecting rod 136 and the connecting hole can be set to rectangular. The connecting rod 136 can also drive the locking rod 131 to move smoothly along the axial direction of the connecting hole, thereby ensuring the stability of the first locking tongue 132 on the locking rod 131 moving between the first and second positions.

[0117] See next Figure 9-13 Two stop members 1123 are provided on the end face of the locking ring 112. These two stop members 1123 correspond to two first lock holes 1121 respectively, and are respectively located on the end face of the locking ring 112 near the first lock hole 1121. During the rotation, the first locking tongue 132 abuts against the stop member 1123. At this time, the first locking tongue 132 is aligned with a first lock hole 1121 on the locking ring 112. At this time, force is applied to the locking rod 131, so that the first locking tongue 132 moves to the second position and locks with the first lock hole 1121, thereby achieving the purpose of fixing the display screen 200.

[0118] In the exemplary embodiments, the position of the stop member is not fixed and can be adjusted as needed by those skilled in the art. For example, the stop member can also be disposed on the outer peripheral surface of the locking ring 112.

[0119] In an exemplary embodiment, the first locking structure and the second locking structure are aligned, meaning that in addition to the first locking tongue 132 abutting against the stop member 1123, the locking rod 131 can also abut against the stop member 1123. Furthermore, in an exemplary embodiment, the stop member 1123 can be a stop block.

[0120] It should be noted that when there are three or more first locking holes 1121, the same number of stop members 1123 as the number of first locking holes 1121 can be provided. Each stop member 1123 is located on the end face of the locking ring 112 near the first locking hole 1121. To prevent the stop members 1123 from affecting the rotation of the rotating assembly 12 and driving the locking assembly 13 to rotate, the distance between the stop member 1123 and the first surface of the rotating flange 121 is less than the distance between the first position and the first surface of the rotating flange 121. It should also be noted that when the first locking structure is the second locking tongue 1122 and the second locking structure is the second locking hole 1311, stop members 1123 can also be provided on the outer circumferential surface of the locking ring 112 corresponding to each locking structure, according to the number of the first locking structures. The distance between each stop member 1123 and the first surface is less than the distance between the first position and the first surface.

[0121] Combination Figure 11-13 The rotation method of the rotating mechanism 1 of this application will be described.

[0122] like Figure 11 As shown, the first locking tongue 132 on the locking rod 131 is locked in place with a first locking hole 1121 on the locking ring 112. At this time, the rotating flange 121 cannot rotate. Since the second side of the rotating flange 121 is provided with a display screen 200, the display screen 200 is in a fixed state.

[0123] During unlocking, a force is applied to handle 137 from the second surface to the first surface, driving connecting rod 136 to move locking rod 131 away from the first surface, i.e., towards the second position. When the first locking tongue 132 is in the second position, the first locking tongue 132 disengages from the first locking hole 1121, and the first locking tongue 132 and the first locking hole 1121 are unlocked. The rotating flange 121 can then rotate the display screen 200, thereby adjusting the display orientation of the display screen 200. Figure 12 This is a schematic diagram of the rotating flange 121 during rotation, at which time the locking rod 131 is positioned between the two first locking holes 1121.

[0124] When the first latch 132 abuts against the stop 1123 at the other first lock hole 1121, the display screen 200 rotates to the target position, and the first latch 132 aligns with the first lock hole 1121. At this time, a force is applied in the opposite direction to the handle 137 (a force from the first surface to the second surface), driving the connecting rod 136 to move the locking rod 131 towards the first surface, that is, towards the direction of the first position. Figure 13 As shown, when the first locking tongue 132 is in the first position, the first locking tongue 132 is finally locked to the new first locking hole 1121.

Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
