Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a connection lock and a display screen. Background Technology

[0002] Currently, large display screens are generally required for events such as stages and exhibitions, but excessively large screens are inconvenient to transport. The current solution is to use splicing locks to combine multiple small screens into one large screen, thereby increasing the display size. During splicing, multiple small screens are typically mounted on a frame, and then the frames are interlocked using splicing locks to combine them into a single large display screen.

[0003] However, existing splicing locks used for locking the frame cause unstable connections between the spliced ​​small-sized displays after locking, resulting in shaking and step differences. Utility Model Content

[0053] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0054] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0055] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] Figure 1 This is a schematic diagram of the structure of the connection lock provided in an embodiment of this application, as shown below. Figure 1 As shown, this application embodiment provides a connection lock, including: a first locking member 100 and a second locking member 200 used in cooperation with each other.

[0057] Combination Figure 1 See Figure 2 The first locking component 100 includes: a handle 10, a bushing assembly 20, a locking rod 30, and a fixed base 40; one end of the handle 10 is provided with a cam portion 11, and a drive portion 12 is provided on the cam portion 11; the bushing assembly 20 is rotatably connected to the cam portion 11; the locking rod 30 is movably and limitedly connected within the bushing assembly 20, one end of the locking rod 30 is provided with a driven portion 31 that cooperates with the drive portion 12, and the other end is provided with a locking head 32; the fixed base 40 has a mounting hole 41, and the bushing assembly 20 is movably and limitedly connected within the mounting hole 41; a first spring 50 is provided between the bushing assembly 20 and the fixed base 40; the second locking component 200 is located on the side where the locking head 32 is located, and the second locking component 200 has a locking hole 201 that cooperates with the locking head 32;

[0058] Handle 10 in Figure 1 The position shown is the first position. When a locking operation is required, the handle 10 rotates from the first position to the second position along the first direction, causing the locking rod 30 to move along the second direction and connecting the driving part 12 with the driven part 31. In this embodiment, the first direction is rotation along the axial direction of the locking rod 30. Figure 1 Taking the orientation in the middle as an example, the first direction is along Figure 1 The locking lever 30 rotates upward in the axial direction. When the handle 10 is in the first position, the angle between the handle 10 and the locking lever 30 is defined as approximately 90 degrees (of course, it can also be other degrees, but this application embodiment does not specifically limit it). The handle 10 rotates from the first position to the second position along the first direction, which means that the handle 10 rotates upward by a certain angle. For example, the handle 10 rotates to the second position, which means that the handle 10 rotates relative to the locking lever 30 by N degrees. The value of N can be set according to different needs. For example, the value of N is 150 degrees.

[0059] When the handle 10 is rotated upward to the second position, based on the structure of the cam portion 11, the handle 10 will drive the locking rod 30 to move a certain distance along the second direction, so that the driving portion 12 is connected to the driven portion 31. In this application, the second direction refers to the direction from the first locking member 100 to the second locking member 200, that is, the axial direction of the locking rod 30.

[0060] After the drive unit 12 is connected to the driven unit 31, the handle 10 continues to rotate along the first direction from the second position to the third position, so as to Figure 1 Taking the position shown as an example, if the handle 10 continues to rotate upward, such as by 30 degrees, the handle 10 is in the third position. The angle between the handle 10 and the locking bar 30 is approximately 180 degrees. When the handle 10 rotates from the second position to the third position, the driving part 12 drives the driven part 31 to rotate along the circumferential direction of the locking bar 30 so that the lock head 32 is aligned with the lock hole 201.

[0061] After the lock head 32 is aligned with the lock hole 201, the handle 10 moves in the second direction, causing the bushing assembly 20 and the lock rod 30 to move synchronously and compress the first spring 50. The purpose of the handle 10 moving the bushing assembly 20 and the lock rod 30 synchronously in the second direction is to make the lock head 32 on the lock rod 30 extend into the lock hole 201.

[0062] Then, the handle 10 rotates in the opposite direction of the first direction, causing the lock head 32 to be misaligned with the lock hole 201, and locking the lock head 32 with the second locking member 200. The handle 10 rotates in the opposite direction of the first direction, that is, the handle 10 rotates downward from the third position back to the first position. When the handle 10 rotates from the third position to the second position, the driving part 12 drives the driven part 31 to rotate, causing the locking rod 30 to rotate, so as to cause the lock head 32 to be misaligned with the lock hole 201. When the handle 10 rotates from the second position to the first position, the cam part 11 on the handle 10 and the elastic force of the first spring member 50 pull the locking rod 30 away from the second locking member 200, so that the lock head 32 locks the second locking member 200, thereby completing the locking between the first locking member 100100 and the second locking member 200200.

[0063] The technical solution provided in this application embodiment enables the connection between two splicing components (such as two displays) through the first locking member 100 and the second locking member 200. The locking rod 30 engages with the lock hole 201 through the lock head 32, and the locking rod 30 is pulled away from the second locking member 200 by the cam part 11 on the handle 10 and the first spring member 50, so that the locking rod 30 tightens the second locking member 200, thereby ensuring the relative position between the first locking member 100 and the second locking member 200 is stable, thus completing the splicing between the two splicing components (such as two displays), effectively preventing the two splicing components (such as two displays) from shaking, ensuring that there is no step difference between the two splicing components after splicing, and the connecting lock has the characteristics of stable structure, simple operation, and strong practicality.

[0064] The technical solutions provided in the embodiments of this application will be described in further detail below.

[0065] The connecting lock provided in this application embodiment can be used for splicing two splicing components, including but not limited to connecting two displays. The display includes a screen body and a connecting lock. The screen body includes a frame and a screen panel, and the connecting lock can be disposed on the frame. When it is necessary to splice two displays together, locking is achieved by the first locking member 100 on one display cooperating with the second locking member 200 on the other display, or by the second locking member 200 on one display cooperating with the first locking member 100 on the other display, thereby realizing the splicing of the two displays.

[0066] See also Figure 2 In this embodiment, the drive unit 12 and the handle 10 are integrally formed or fixedly connected. One possible implementation is that one end of the handle 10 has two opposing cam portions 11, and the drive unit 12 is provided on the side of one cam portion 11 facing the other cam portion 11. The drive unit 12 and the cam portion 11 can be integrally formed, or can be fixedly connected by fasteners or by snap-fit ​​connection.

[0067] One possible implementation of the driven part 31 is that the driven part 31 and the locking rod 30 are integrally formed or fixedly connected. The driven part 31 is disposed at one end of the locking rod 30, and is fixedly connected by fasteners or by snap-fit ​​connection, among other things.

[0068] Further, see also Figure 1 and Figure 2In some feasible embodiments of this application, the handle 10 rotates from the second position to the third position along the first direction, and the driving part 12 drives the driven part 31 to rotate along the circumferential direction of the locking rod 30 in the following manner: the driving part 12 is a fan-shaped face gear, and the face gear has a plurality of first meshing teeth 121 on its arc-shaped end face, and the plurality of first meshing teeth 121 are distributed along the axial direction of the locking rod 30; the driven part 31 is a spur gear, and the spur gear has a plurality of second meshing teeth 311, and the plurality of second meshing teeth 311 are distributed along the circumferential direction of the locking rod 30.

[0069] When the handle 10 rotates from the first position to the second position along the first direction, the first meshing tooth 121 on the face gear and the second meshing tooth 311 on the spur gear are not yet connected. At this time, the handle 10 drives the locking rod 30 to move a certain distance along the second direction. When the handle 10 is in the second position, the first meshing tooth 121 and the second meshing tooth 311 begin to connect. When the handle 10 rotates from the second position to the third position, the first meshing tooth 121 on the face gear and the second meshing tooth 311 on the spur gear engage and connect. The face gear drives the spur gear to rotate along the circumferential direction of the locking rod 30. As the spur gear rotates, it drives the locking rod 30 to rotate synchronously along the circumferential direction of the locking rod 30, thereby aligning the lock head 32 with the lock hole 201. Thus, the engagement of the face gear and the spur gear can also achieve the effect of amplifying the transmission ratio.

[0070] Further, see also Figure 2 In some feasible embodiments of this application, the arc-shaped end face of the drive unit 12 is further provided with a smooth section 122 that smoothly transitions with the first meshing tooth 121; when the handle 10 rotates from the first position to the second position, the drive unit 12 contacts and connects with the driven unit 31 through the smooth section 122; during this process, it is equivalent to the handle 10 driving the drive unit 12 to rotate freely, and the smooth section 122 can better guide the second meshing tooth 311 to contact the first meshing tooth 121, making the subsequent meshing connection smoother. When the handle 10 rotates from the second position to the third position, the drive unit 12 engages and connects with the second meshing tooth 311 of the driven unit 31 through the first meshing tooth 121, and drives the driven unit 31 to rotate.

[0071] See Figures 1 to 3 In some feasible embodiments of this application, one implementation of the bushing assembly 20 is that the bushing assembly 20 includes a first bushing 21 and a second bushing 22.

[0072] The first bushing 21 is rotatably connected to the cam portion 11. One way to achieve this rotatable connection is that the first bushing 21 is provided with a transition shaft 211. The transition shaft 211 can be integrally formed with the first bushing 21 or fixedly mounted on the first bushing 21. The cam portion 11 is provided with a transition hole 111 that mates with the transition shaft 211. The transition shaft 211 extends into the transition hole 111 to achieve a rotatable connection between the first bushing 21 and the cam handle.

[0073] See also Figure 3 The first bushing 21 is provided with a first sliding groove 212 extending in the circumferential direction and a driving port 213 corresponding to the position of the driving part 12. There may be two first sliding grooves 212, which are arranged opposite to each other.

[0074] Combination Figure 1 and Figure 3 See Figure 2 The second bushing 22 is sleeved on the outside of the first bushing 21 and abuts against the cam part 11; the second bushing 22 is provided with a second slide groove 221 at the position corresponding to the first slide groove 212, and the size of the second slide groove 221 is larger than the size of the first slide groove 212 along the axial direction; the first spring member 50 is sleeved on the outside of the second bushing 22; the locking rod 30 is provided with a first limiting member 33 at the position corresponding to the first slide groove 212, the first limiting member 33 extends into the first slide groove 212 and the second slide groove 221, and the driven part 31 extends out through the drive port 213.

[0075] When the handle 10 is rotated from the first position to the second position, based on the structure of the cam part 11 and the second slide groove 221, and based on the limiting cooperation between the first slide groove 212 and the first limiting member 33, the handle 10 drives the first bushing 21 and the locking rod 30 to move synchronously relative to the second bushing 22, so that the locking rod 30 moves a distance along the second direction, so that the driving part 12 and the driven part 31 are connected through the driving port 213.

[0076] When the handle 10 moves in the second direction, based on the limiting cooperation between the first limiting member 33 on the locking bar 30 and the first slide groove 212 and the second slide groove 221, the handle 10 can drive the first bushing 21, the locking bar 30 and the second bushing 22 to move synchronously relative to the fixed seat 40, and compress the first spring member 50 through the second bushing 22, so that the lock head 32 can extend into the lock hole 201.

[0077] When the handle 10 rotates in the opposite direction of the first direction, based on the connection between the drive part 12 and the driven part 31, the lock head 32 and the lock hole 201 can be misaligned. Based on the limiting cooperation between the cam part 11, the first limiting member 33 and the first slide groove 212 and the second slide groove 221, the handle 10 can drive the first bushing 21 and the locking rod 30 to move relative to the second bushing 22 in the opposite direction of the second direction, thereby causing the locking rod 30 to tighten the second locking member 200, so as to ensure the relative position between the first locking member 100 and the second locking member 200 is stable.

[0078] See also Figure 2 and Figure 3 To ensure smoother movement of the first bushing 21 relative to the second bushing 22 in the second direction, in this embodiment, the first bushing 21 is provided with a third groove 214 extending along the axial direction of the first bushing 21; the second bushing 22 is provided with a second limiting member 222 at a position corresponding to the third groove 214, the second limiting member 222 extending into the third groove 214; when the handle 10 is rotated from the first position to the second position, the second limiting member 222 cooperates with the third groove 214 to make the first bushing 21 move along the extension direction of the third groove 214 and limit the movement distance of the first bushing 21.

[0079] When the handle 10 is rotated from the first position to the second position, the handle 10 can drive the first bushing 21 and the locking rod 30 to move synchronously relative to the second bushing 22. When the first bushing 21 moves, the second limiting member 222 moves along the extension direction of the third slide groove 214. Through the cooperation between the second limiting member 222 and the third slide groove 214, the trajectory of the first bushing 21 relative to the second bushing 22 can be better limited, ensuring the smoothness and accuracy of the movement of the first bushing 21. It can also prevent the first bushing 21 from rotating in the circumferential direction relative to the second bushing 22, thereby ensuring the accuracy of the movement of the locking rod 30 and ensuring that the driving part 12 and the driven part 31 can be more accurately aligned.

[0080] In one embodiment of this application, the second limiting member 222 is disposed on the second bushing 22 in such a way that the second limiting member 222 is provided with a threaded structure and the second bushing 22 is provided with a first threaded hole 223. The second limiting member 222 is threadedly connected and fixed to the first threaded hole 223, and a part of the second limiting member 222 extends into the third sliding groove 214.

[0081] See Figure 2To prevent the locking rod 30 from wobbling radially relative to the first bushing 21, in some feasible embodiments of this application, the locking rod 30 is provided with a support protrusion 34, the diameter of which matches the inner diameter of the first bushing 21. With this arrangement, after the locking rod 30 is fitted onto the first bushing 21, while ensuring that the locking rod 30 can rotate circumferentially within the first bushing 21, the radial distance between the locking rod 30 and the first bushing 21 can be relatively small, reducing the relative displacement between them in the radial direction. This prevents the locking rod 30 from wobbling radially relative to the first bushing 21 and ensures more stable circumferential rotation of the locking rod 30 within the first bushing 21. Simultaneously, with this arrangement, the diameter of other areas of the locking rod 30 can be smaller than the inner diameter of the first bushing 21, thereby reducing the weight of the locking rod 30 and the overall weight of the lock assembly.

[0082] In this embodiment, after the lock head 32 is aligned with the lock hole 201, the handle 10 moves in the second direction, causing the bushing assembly 20 and the lock rod 30 to move synchronously, so that the lock head 32 extends into the lock hole 201. To further define the movement trajectory and distance between the bushing assembly 20 and the fixed base 40, please refer to [reference needed]. Figure 2 The second bushing 22 is provided with a fourth slide groove 224 extending along the axial direction of the second bushing 22; the fixed seat 40 is provided with a third limiting member 42, which extends into the fourth slide groove 224; wherein, when the handle 10 moves along the second direction, the third limiting member 42 cooperates with the fourth slide groove 224 to make the second bushing 22 move along the extension direction of the fourth slide groove 224 and limit the movement distance of the second bushing 22.

[0083] Once the lock head 32 is aligned with the lock hole 201, the handle 10 moves along the second direction, that is, the handle 10 drives the lock rod 30 and the bushing assembly 20 to move in the direction of the second locking member 200, and the lock head 32 is inserted into the lock hole 201. The third limiting member 42 slides in the fourth sliding groove 224, restricting the movement trajectory of the second bushing 22 relative to the fixed seat 40, that is, limiting the movement trajectory of the bushing assembly 20 relative to the fixed seat 40, and also limiting the maximum displacement of the bushing assembly 20 and the lock rod 30 relative to the fixed member along the second direction.

[0084] In one embodiment of this application, the third limiting member 42 is disposed on the fixed seat 40 in such a way that the third limiting member 42 is provided with a threaded structure and the fixed seat 40 is provided with a second threaded hole. After the third limiting member 42 is threadedly connected and fixed to the second threaded hole, a part of the third limiting member 42 extends into the fourth sliding groove 224 to limit the trajectory of the bushing assembly 20 relative to the fixed seat 40.

[0085] See Figure 1 and Figure 2In some feasible embodiments of this application, to lock the position of the handle 10 when it is in the first position, a locking member 60 is also provided on the handle 10. One configuration of the locking member 60 is as follows: the handle 10 has a receiving groove 13, one end of the first bushing 21 is disposed within the receiving groove 13 and rotatably connected to the handle 10; the end of the first bushing 21 located within the receiving groove 13 has a limiting groove 215; the handle 10 is rotatably provided with the locking member 60. When the handle 10 is in the first position, the locking end 61 of the locking member 60 can connect with the limiting groove 215 to lock the current position of the handle 10 and restrict the handle 10 from rotating in the first direction. After the locking end 61 of the locking member 60 is connected with the limiting groove 215 on the first bushing 21, the handle 10 cannot rotate in the first direction, thereby limiting the relative movement between the first bushing 21, the locking rod 30, and the second bushing 22. When the handle 10 is rotated back to the first position in the opposite direction of the first direction, the lock head 32 is locked with the second lock member 200. At this time, the relative position of the lock rod 30 can be locked by the connection between the locking end 61 of the locking member 60 and the limiting groove 215, so as to ensure the stability of the lock between the lock head 32 and the second lock member 200.

[0086] See also Figure 2 In one embodiment of this application, the locking member 60 may include a button 62, a limiting rod 63, and a second spring 64. The handle 10 has an opening 14 on its side that communicates with the receiving groove 13. The limiting rod 63 is rotatably disposed within the receiving groove 13. The button 62 is movably disposed at the opening 14 and drivenly connected to the limiting rod 63. The second spring 64 is connected to both the button 62 and the handle 10. The button 62 can drive the connection and separation between the limiting rod 63 and the limiting groove 215. The limiting rod 63 can be rotatably connected to the handle 10 through a hole in its middle. A portion of the limiting rod 63 located on both sides of the hole serves as a locking end 61, and the other portion is connected to the button 62. The button 62 can be pressed or slid to move away from the locking end 61 based on a lever mechanism.

[0087] For example, when the handle 10 needs to be rotated, press button 62 first, causing button 62 to disengage the locking end 61 from the limiting groove 215, thereby unlocking the handle 10 from the first bushing 21, allowing the handle 10 to rotate accordingly. After the lock head 32 and the lock hole 201 are misaligned, when the handle 10 rotates back to the first position in the opposite direction of the first direction, button 62 is activated by the second spring 64, causing the locking end 61 of the locking member 60 to connect with the limiting groove 215, thereby locking the relative position of the handle 10 and the first bushing 21 and ensuring the stability of the lock between the lock head 32 and the second locking member 200.

[0088] Based on the above embodiments, this application also provides a display screen, including: a screen body and a connecting lock, wherein the connecting lock is the connecting lock described in the above embodiments, and the connecting lock is disposed on the screen body. When it is necessary to splice two display screens together, locking is achieved by the cooperation of the first locking member 100 on the display screen and the second locking member 200 on the other display screen, or by the cooperation of the second locking member 200 on the display screen and the first locking member 100 on the other display screen, thereby realizing the splicing of two display screens.

[0089] The display screens in this application embodiment include, but are not limited to: transparent display screens, liquid crystal display screens, OLED (Organic Light-Emitting Diode) display screens, MicroLED (MicroLight Emitting Diode) display screens, etc. For the specific structure of the connection lock, please refer to the implementation method of the connection lock described in the above embodiments; it will not be repeated here.

[0090] In summary, the technical solution provided in this application embodiment enables the connection between two splicing components (such as two displays) through the first locking member 100 and the second locking member 200. The locking rod 30 engages with the lock hole 201 through the lock head 32, and is pulled away from the second locking member 200 by the cam part 11 on the handle 10 and the first spring member 50, so that the locking rod 30 tightens the second locking member 200, thereby ensuring the relative position between the first locking member 100 and the second locking member 200 is stable, thus completing the splicing between the two splicing components (such as two displays), effectively preventing the two splicing components (such as two displays) from shaking, ensuring that there is no step difference between the two splicing components after splicing, and the connecting lock has the characteristics of stable structure, simple operation, and strong practicality.
