Description

Technical Field

[0001] This application relates to the field of display device technology, and in particular to a connection lock, a display screen bezel, and a display screen. Background Technology

[0002] Larger displays are typically formed by connecting multiple smaller display units together using interlocking mechanisms. Each display unit generally includes a frame and a screen mounted on the frame. The frames of adjacent display units are connected and fixed together using interlocking mechanisms to form a larger display.

[0003] Currently, the connection lock for connecting the display unit generally includes a rotating handle. By rotating the rotating handle 90 degrees, the locking or unlocking of two adjacent frames can be completed. When the rotating handle of the connection lock is in one of the unlocking or locking states, it extends into the screen area of ​​the display.

[0004] For displays with transparent or penetrating screens, the rotation handle will be visible when it is extended into the screen area, which can easily affect the overall visual effect of the transparent or penetrating screen. Summary of the Invention

[0053] The beneficial effects of the embodiments of this application are as follows: The connecting lock provided in this application, by providing a rotatable mating part on the lock tongue, can have a first position and a second position relative to the lock tongue; when the mating part is in the first position, the driving protrusion on the driving component can engage with the mating groove on the mating part, so that the driving component can drive the lock tongue to rotate when it rotates; when the driving component drives the lock tongue to rotate to the position of engaging with the lock block, the abutting protrusion on the mating end face of the mating part abuts against the lock block, so that the mating part is pushed by the lock block to the second position; when the mating part is in the second position, the lock tongue and the lock block are locked, and the driving protrusion on the driving component also disengages from the mating groove on the mating part. At this time, if the handle is continued to be turned, the driving component will no longer drive the lock tongue to rotate. In this way, when the connecting lock is applied to the display screen bezel, the handle can be positioned in a position that can be covered by the display screen bezel when the connecting lock is in the unlocked state. After the connecting lock is locked, if the handle is continued to be turned, the handle can be turned back to a position that can be covered by the display screen bezel, thereby effectively preventing the handle in the connecting lock from affecting the overall visual effect of the display screen.

[0079] Please see Figures 1 to 6This application provides a connecting lock 100 for connecting a first component 301 and a second component 302 to be connected. The connecting lock 100 includes a first connecting component 10 and a second connecting component 20. The first connecting component 10 is disposed on the first component 301 and includes the connecting lock 100. The second connecting component 20 is disposed on the second component 302 and includes a handle 21, a driving component 22, a mating component 23, and a locking tongue 24, wherein the driving component 22 and the locking tongue 24 are both rotatably disposed relative to the second connecting component 20. The handle 21 is mounted on the drive component 22 and is used to drive the drive component 22 to rotate. The drive component 22 has a drive protrusion 2221. The locking tongue 24 has a mating end face 243, which is used to cooperate with the locking block 11 to lock the first connecting component 10 and the second connecting component 20. The mating member 23 has a mating groove 231 and an abutment protrusion 232. The mating member 23 is rotatably mounted on the locking tongue 24 and has a first position and a second position relative to the locking tongue 24. When the mating part 23 is in the first position, the mating groove 231 engages with the drive protrusion 2221 to drive the locking tongue 24 to rotate through the mating part 23, and the abutting protrusion 232 protrudes from the mating end face 243. The abutting protrusion 232 is used to abut against the locking block 11 when the locking tongue 24 engages with the locking block 11 to rotate the mating part 23 to the second position. When the mating part 23 is in the second position, the mating groove 231 disengages from the drive protrusion 2221 to allow the handle 21 to continue rotating to the designated position.

[0080] It should be noted that this application does not limit the specific products corresponding to the first connector 301 and the second connector 302. For example, the first connector 301 and the second connector 302 can both be display screen bezels 200 or both be display screen housings, but are not limited thereto. In this embodiment, the example is that both the first connector and the second connector are display screen bezels 200.

[0081] The connecting lock 100 provided in this application, by providing a rotatable mating part 23 on the lock tongue 24, and making the abutting protrusion 232 of the mating part 23 protrude from the mating end face 243 of the lock tongue 24, allows the mating part 23 to be in a first position relative to the lock tongue 24 before the lock tongue 24 mates with the lock block 11. Figure 4 As shown, at this time, the driving protrusion 2221 on the driving component 22 can engage with the mating groove 231 on the mating component 23, so that when the driving component 22 rotates, it can drive the locking tongue 24 to rotate; when the driving component 22 drives the locking tongue 24 to rotate to the position that engages with the locking block 11, the abutting protrusion 232 on the mating component 23 begins to abut against the locking block 11. As the driving part rotates, the mating component 23 rotates to the second position under the push of the locking block 11, as shown. Figure 5As shown; when the mating part 23 rotates to the second position, the driving protrusion 2221 disengages from the mating groove 231. At this time, if the handle 21 is rotated further, the driving part 22 will no longer drive the locking tongue 24 to rotate.

[0082] When the connecting lock 100 is applied to the display screen bezel 200, the handle 21 is initially positioned within the bezel 200's coverage area. Rotating the handle 21 causes the drive mechanism to engage the latch 24 with the locking block 11, and continuing to rotate the handle 21 moves it to the designated position. It can be understood that when the connecting lock 100 is fully unlocked, the handle 21 is in its initial state. Figure 3 As shown. When the screen on the display bezel 200 is a transparent or penetrating screen, to avoid the handle 21 affecting the overall visual effect of the display, the designated position of the handle 21 is also located in a position that the display bezel 200 can cover. For example, the handle 21 can be rotated 180 degrees from its initial position to its designated position, that is, the handle 21 can be rotated from its initial position to its designated position. Figure 3 Rotate the position in the middle to Figure 2 In this embodiment, the handle 21 is typically a long handle-like structure, allowing it to rotate from a position parallel to the display frame to a position where it is parallel to the display frame again. In this embodiment, the handle 21 being located in a position that can be obscured by the display frame 200 means that the handle 21 is within the orthographic projection area of ​​the display frame 200.

[0083] The first connecting component 10 in the connecting lock 100 includes a locking block 11. The specific structure of the locking block 11 is not limited in this embodiment. The locking block 11 is used to cooperate with the bolt 24 to achieve locking of the connecting lock 100. Figure 3 As shown, a lock groove 111 is formed on the lock block 11, and the lock tongue 24 completes the locking of the lock 100 by being inserted into the lock groove 111.

[0084] Please refer to the following: Figures 7 to 10 The second connecting component 20 in the connecting lock 100 includes a handle 21, a drive component 22, a mating component 23, and a locking tongue 24.

[0085] The handle 21 is mounted on the drive component 22, so that rotating the handle 21 can drive the drive component 22 to rotate. The handle 21 can be in the shape of a long handle. The connection position between the handle 21 and the drive component 22 can be located at one end of the handle 21 or at the middle of the handle 21, as shown in Figure 7. This application will use the example of the connection position between the handle 21 and the drive component 22 being located at the middle of the handle 21 for illustration.

[0086] The driving component 22 has a driving protrusion 2221, which engages with the mating groove 231 to drive the latch 24 to rotate. In some embodiments, the driving component 22 may include a rotating bushing 221. The latch 24 is rotatably sleeved on the rotating bushing 221. The driving protrusion 2221 is located circumferentially on the rotating bushing 221, and axially on the rotating bushing 221, so that the driving protrusion 2221 corresponds to the mating groove 231 of the mating component 23 on the latch 24. Thus, after the driving protrusion 2221 engages with the mating groove 231, the rotating bushing 221 can drive the latch 24 to rotate when it rotates. The two ends of the rotating bushing 221 are rotatably mounted on the second member to be connected 302, so that both the latch 24 and the driving component 22 are rotatably mounted relative to the second member to be connected 302. The two ends of the rotating bushing 221 can be rotatably mounted on the second part to be connected 302. The two ends of the rotating bushing 221 can be directly rotatably mounted on the second part to be connected 302, or the two ends of the rotating bushing 221 can be rotatably mounted on a base, and then the base is fixedly mounted on the second part to be connected 302, but it is not limited to this.

[0087] Rotating the handle 21 drives the drive component 22 to rotate, that is, rotating the handle 21 drives the rotating bushing 221 to rotate. The handle 21 can be directly fixed to one end of the rotating bushing 221, or it can be fixed to one end of a drive rod 25, and then the rotating bushing 221 is sleeved on the drive rod 25, so that the handle 21 can drive the rotating bushing 221 to rotate through the drive rod 25.

[0088] The bolt 24 engages by fitting into the lock groove 111 on the lock block 11. Figure 3 As shown, the lock groove 111 is an open through groove. When locked, the lock tongue 24 enters from the opening of the lock groove 111 until the mating end face 243 on the lock tongue 24 contacts the bottom surface of the lock groove 111, at which point the lock tongue 24 stops rotating.

[0089] The mating component 23 is rotatably mounted on the latch 24. When the lock 100 is in the unlocked state, the mating component 23 is in a first position relative to the latch 24. In the first position, the mating groove 231 engages with the drive protrusion 2221, allowing the drive protrusion 2221 to drive the latch 24 to rotate. Since the abutment protrusion 232 protrudes from the mating end face 243, as the latch 24 rotates toward the lock groove 111, the abutment protrusion 232 contacts the bottom surface of the lock groove 111. The latch 24 continues to rotate, and the bottom surface of the lock groove 111 pushes the mating component 23 to rotate through the abutment protrusion 232. At the same time, the mating groove 231 gradually disengages from the abutment protrusion 232 until the latch 24 stops rotating, and the mating component 23 rotates to the second position. In the second position, the mating groove 231 is completely disengaged from the abutment protrusion 232.

[0090] In this embodiment, the specific location of the mating member 23 on the latch 24 is not limited. To avoid the side walls of the lock groove 111 or other components in the lock 100 affecting the position of the mating member 23, such as... Figure 3 and Figure 7 As shown, in some embodiments, a mounting groove 241 may be formed on the latch 24. The mounting groove 241 extends along the normal direction of the mating end face 243 and penetrates the mating end face 243, so that the mating part 23 is rotatably disposed in the mounting groove 241. In this way, the upper and lower sides of the mating part 23 can be shielded by the side wall of the mounting groove 241, thereby effectively preventing other parts from touching the mating part 23 and affecting the position of the mating part 23, and ensuring the stable operation of the connecting lock 100.

[0091] When the mating part 23 is disposed in the mounting groove 241 of the latch 24, the drive protrusion 2221 is also disposed in the mounting groove 241 to mate with the mating groove 231. To assemble the latch 24 with the rotating bushing 221, the drive component 22 also includes a drive accessory 222. The drive protrusion 2221 is formed on the drive accessory 222, which is also located in the mounting groove 241. Then, the drive accessory 222 and the latch 24 are fitted together onto the rotating bushing 221. To allow the rotating bushing 221 to drive the drive accessory 222 to rotate, the drive accessory 222 and the rotating bushing 221 are mated by a first circumferential limiting structure, which is used to allow the rotating bushing 221 to drive the drive accessory 222 to rotate. This application does not limit the specific structure of the first circumferential limiting structure. For example, the first circumferential limiting structure may have a non-circular hole such as a triangle, rectangle, polygon, or ellipse on the drive accessory 222, and the rotating bushing 221 may have an outer diameter with a corresponding cross-section. Alternatively, the first circumferential limiting structure may have a limiting protrusion 2222 on one of the drive accessory 222 and the rotating bushing 221, and a limiting notch 2213 that mates with the limiting protrusion 2222 on the other. In this embodiment, to facilitate the locking tongue 24 and the drive accessory 222 being fitted onto the rotating bushing 221, a limiting protrusion 2222 is formed on the inner circumference of the drive accessory 222, and a limiting notch 2213 that mates with the limiting protrusion 2222 is formed on the rotating bushing 221. Figure 4 and Figure 5 As shown in the embodiments of this application, the limiting protrusion 2222 and the limiting notch 2213 are both rectangular, but the embodiments are not limited thereto.

[0092] like Figure 10As shown, in some embodiments, the rotating sleeve 221 further has a first limiting surface 2211 and a second limiting surface 2212 facing away from each other in the axial direction, and the locking tongue 24 is sleeved in the area between the first limiting surface 2211 and the second limiting surface 2212. The second connecting assembly 20 also includes a first limiting member 26 and a second limiting member 27. The first limiting member 26 is located on one side of the first limiting surface 2211, and the end of the rotating sleeve 221 near the first limiting surface 2211 is rotatably engaged with the first limiting member 26. The second limiting member 27 is located on one side of the second limiting surface 2212, and the end of the rotating sleeve 221 near the second limiting surface 2212 is rotatably engaged with the second limiting member 27. Since the locking tongue 24 is rotatably sleeved on the rotating sleeve 221, the first limiting member 26 and the second limiting member 27 can restrict the axial position of the locking tongue 24 on the rotating sleeve 221, ensuring that the position of the locking tongue 24 corresponds to the position of the locking groove 111 on the axial direction of the rotating sleeve 221. Thus, when the two ends of the rotating sleeve 221 are rotatably mounted on the second connecting member 302, the first limiting member 26 and the second limiting member 27 can be fixedly mounted on the second connecting member 302. By setting the first limiting member 26 and the second limiting member 27 in the second connecting assembly 20, not only can the axial position of the locking tongue 24 on the rotating sleeve 221 be limited, but also an installation object is provided for the rotational installation of the rotating sleeve 221, making the second connecting assembly 20 a whole and facilitating the installation and disassembly of the second connecting assembly 20 on the second connecting member 302.

[0093] like Figure 10 As shown, in some embodiments, the rotating bushing 221 has a mating portion 2214. The locking tongue 24 is rotatably fitted onto the mating portion 2214. The central axis of rotation of the rotating bushing 221 is offset from the central axis of the mating portion, i.e., the mating portion 2214 forms an eccentric wheel structure. When the mating groove 231 disengages from the driving protrusion 2221 and the handle 21 is rotated to the designated position, the central axis of the rotating bushing 221 is located on the side of the central axis of the mating portion 2214 closer to the locking block 11. During this process, the mating portion 2214 drives the locking tongue 24 to move closer to the locking block 11, causing the stop structure 242 at the end of the locking tongue 24 to abut against the locking block 11, thereby ensuring the locking of the locking tongue 24 and the locking block 11. Furthermore, by causing the mating part 2214 to move the locking tongue 24 toward the locking block 11, the size of the locking tongue 24 protruding from the second member to be connected can be reduced after the connecting lock 100 is locked, so that when the connecting lock 100 is applied to the display screen bezel 200, it can adapt to a narrower bezel.

[0094] It is understood that when the rotating bushing 221 also has a first limiting surface 2211 and a second limiting surface 2212 facing away from each other, the area between the first limiting surface 2211 and the second limiting surface 2212 on the rotating bushing 221 forms a mating part 2214.

[0095] like Figure 6 As shown, in some embodiments, when the first circumferential limiting structure includes a limiting notch 2213 formed on the circumferential surface of the mating part 2214 and a limiting protrusion 2222 formed on the driving accessory 222, the limiting notch 2213 has opposing first driving surfaces 221a and second driving surfaces 221b. The first driving surface 221a is used to drive the driving accessory 222 to rotate when the handle 21 rotates from the initial position to the designated position. The second driving surface 221b is used to drive the driving accessory 222 to rotate when the handle 21 rotates from the designated position to the initial position. When the mating part 2214 forms an eccentric wheel structure, the angle between the first driving surface 221a and the plane determined by the central axis of rotation of the rotating bushing 221 and the central axis of the mating part 2214 can be 3°-10°, and the first driving surface 221a is inclined towards the plane. In this way, when the handle 21 rotates to the designated position, it effectively prevents the mating part 2214 from rotating under external forces such as shaking, which could cause the locking lock 100 to not lock properly. For example, the angle between the first driving surface 221a and the plane defined by the central axis of rotation of the rotating bushing 221 and the central axis of the mating part 2214 can be 3°, 4°, 5°, 6°, 7°, 8°, 9°, or 10°, but is not limited to this. Figure 6 As shown, the embodiment of this application takes 5° as an example for illustration.

[0096] When the driving component 22 includes a driving rod 25, a handle 21 is disposed at one end of the driving rod 25, and a rotating bushing 221 is sleeved on the driving rod 25. Figures 4 to 6 As shown, in some embodiments, the rotating sleeve 221 and the drive rod 25 are engaged by a second circumferential limiting structure, which is used to allow the drive rod 25 to drive the rotating sleeve 221 to rotate. Simultaneously, the drive rod 25 is movably positioned relative to the rotating sleeve 221 in the axial direction, having both a working position extending out of the rotating sleeve 221 and a retracted position. The working position of the drive rod 25 is as follows... Figure 7 and Figure 9 As shown, the storage position of the drive rod 25 is as follows: Figure 8 As shown.

[0097] The second circumferential limiting structure can also be a non-circular hole such as a triangle, rectangle, polygon, or ellipse provided on the rotating bushing 221, with the driving rod 25 having an outer diameter whose cross-section is the corresponding shape; or a limiting protrusion 2222 is formed on one of the driving rod 25 and the rotating bushing 221, and a limiting notch 2213 that mates with the limiting protrusion 2222 is formed on the other. In this embodiment, a rectangular hole is formed on the rotating bushing 221 and the cross-section of the driving rod 25 is a corresponding rectangle is used as an example for explanation, but it is not limited to this.

[0098] By making the drive rod 25 movably movable relative to the rotating sleeve 221 along its axial direction, when unlocking or locking is required, the drive rod 25 is moved to the use position relative to the rotating sleeve 221, making it convenient for the user to hold the handle 21 for operation; after the unlocking or locking operation is completed, the drive rod 25 is moved to the storage position relative to the rotating sleeve 221, thereby avoiding the drive rod 25 protruding too much from the display bezel and affecting the overall visual effect of the display screen.

[0099] like Figure 9 and Figure 10 As shown, in some embodiments, the rotating bushing 221 has a mating hole 2215, through which the rotating bushing 221 is fitted onto the drive rod 25. It can be understood that the mating hole 2215 is the rectangular hole in the second circumferential limiting structure. The end of the drive rod 25 away from the handle 21 has a third limiting surface 251. The third limiting surface 251 is oriented towards the handle 21. The second connecting assembly 20 also includes a third limiting member 281. The third limiting member 281 is used to engage with the third limiting surface 251 to prevent the drive rod 25 from disengaging from the mating hole 2215.

[0100] The third limiting member 281 can be a protrusion structure protruding from the inner wall of the mating hole 2215, so that when the third limiting surface 251 of the drive rod 25 moves axially in the rotating sleeve 221 to a position abutting against the protrusion, the drive rod 25 stops moving. In some embodiments, when the second connecting assembly 20 includes a first limiting member 26 and a second limiting member 27, the first limiting member 26 is located at the end of the rotating sleeve 221 near the handle 21, and the second limiting member 27 is located at the end of the rotating sleeve 221 away from the handle 21. The third limiting member 281 can be movably disposed on the first limiting member 26 in a direction perpendicular to the axial direction of the drive rod 25, and a first elastic member 282 is disposed on the side of the third limiting member 281 facing away from the drive rod 25. The first elastic member 282 is used to support the third limiting member 281 protruding radially from the inner wall of the mating hole 2215. The first elastic member 282 can be a spring, but is not limited to this. A guide surface 252 is also formed on the circumferential surface of the drive rod 25. The guide surface 252 is located on the side of the third limiting surface 251 facing the handle 21. The guide surface 252 is used to push the third limiting member 281 to move away from the drive rod 25. For example, the guide surface 252 can be a tapered surface formed on the circumferential surface of the drive rod 25, with the small-diameter end of the tapered surface close to the third limiting surface 251. When the drive rod 25 moves in the direction of extending out of the rotating sleeve 221, as the radial dimension of the guide surface 252 at the third limiting member 281 decreases, the third limiting member 281 protrudes from the inner wall of the mating hole 2215 to abut against the third limiting surface 251, thereby preventing the drive rod 25 from continuing to move in the original direction. When the drive rod 25 moves in the direction of retracting into the rotating sleeve 221, as the radial dimension of the guide surface 252 at the third limiting member 281 increases, the third limiting member 281 is pressed by the guide surface 252 to move away from the drive rod 25, so that the drive rod 25 can be retracted to the storage position.

[0101] In some embodiments, the second connecting assembly 20 further includes a first locking member. The first locking member is used to restrict the free rotation of the handle 21 when the drive rod 25 is in the retracted position, thereby ensuring the reliability of the locking of the connecting lock 100. This application does not limit the specific structure of the first locking member. For example, the first locking member can be a pin structure or a snap-fit ​​structure that fixes the handle 21 to the second connecting member 302, but it is not limited to these.

[0102] like Figure 7As shown, in some embodiments, the first locking component includes a magnetic 291 and a metal part 292 that cooperates with the magnetic 291. The magnetic 291 is disposed on the handle 21, and the metal part 292 is fixedly disposed relative to the second part to be connected 302. For example, the metal part 292 can be directly fixed to the second part to be connected 302 or fixed to the first limiting member 26. The magnetic 291 is disposed on the side of the handle 21 facing the drive rod 25. By pulling the handle 21, the magnetic 291 can be disengaged from the metal part 292, thereby operating the handle 21. By making the first locking component include a magnetic 291 and a metal part 292 that cooperates with the magnetic 291, the use and storage of the handle 21 are convenient, and the locking structure is simple.

[0103] The first connecting component assembly is disposed on the first connecting component 301, providing a locking block 11 that engages with the locking tongue 24.

[0104] Please refer to the following: Figures 11 to 15 In some embodiments, the first connecting assembly 10 may further include a mounting base 12 and a second locking component. The mounting base 12 is used to mount the locking block 11. A mounting post 121 is provided on the mounting base 12. The locking block 11 has an angle adjustment groove 112, which may be formed on the bottom wall of the locking groove 111. The locking block 11 is mounted on the mounting base 12 by allowing the mounting post 121 to be slidably disposed in the angle adjustment groove 112. By adjusting the relative position of the angle adjustment groove 112 and the mounting post 121, the angle of the locking block 11 can be adjusted, thereby achieving angle adjustment between the first connecting member 301 and the second connecting member 302. After adjusting the relative position of the angle adjustment groove 112 and the mounting post 121, their relative position is locked by the second locking component. This embodiment does not limit the specific structure of the second locking component.

[0105] For example, such as Figures 12 to 15As shown, in some embodiments, the locking block 11 is provided with a first locking tooth 113. The first locking tooth 113 is located on the side surface of the locking block 11 facing the mounting base 12. The second locking component includes a locking sleeve 13, a second elastic member 14, and a locking handle 15. The mounting post 121 is disposed through the angle adjustment groove 112 and the mounting base 12. The locking handle 15 is rotatably disposed at the end of the mounting post 121 away from the locking block 11. The locking sleeve 13 is movably sleeved on the mounting post 121 along the axial direction of the mounting post 121, and the end of the locking sleeve 13 facing the locking block 11 has a second locking tooth 131 that cooperates with the first locking tooth 113. The second elastic member 14 is disposed between the locking sleeve 13 and the mounting base 12 along the axial direction of the mounting post 121. The locking handle 15 forms an eccentric structure 151, which has a locking position and an unlocking position. When the eccentric structure 151 rotates to the locking position, it pushes the locking sleeve 13 to move closer to the locking block 11, so that the second locking tooth 131 engages with the first locking tooth 113, thereby locking the locking block 11. When the eccentric structure 151 rotates to the unlocking position, the second elastic element 14 supports the locking sleeve 13 to move away from the locking block 11, so that the second locking tooth 131 disengages from the first locking tooth 113, and the locking block 11 can be rotated to adjust its angle.

[0106] Of course, to facilitate the initial positioning of the locking block 11 after angle adjustment, the mounting base 12 can also be provided with positioning beads 122, and the locking block 11 can be provided with several positioning grooves 114 that cooperate with the positioning beads 122. This prevents the position of the locking block 11 relative to the mounting post 121 from changing before the second locking component locks.

[0107] The connecting lock 100 provided in the above embodiments of this application, when in use, taking the initial position of the connecting lock 100 in the unlocked state as an example, can first rotate the lock block 11 to adjust the angle of the lock block 11, then rotate the locking handle 21 to the locked position, and then pull the drive rod 25 to the use position by the handle 21. When it is extended to the use position, the third limiting surface 251 on the drive rod 25 abuts against the third limiting member 281. Rotating the handle 21 causes the drive rod 25 to drive the rotating bushing 221 to rotate. Since the drive protrusion 2221 on the rotating bushing 221 cooperates with the mating groove 231 on the mating member 23 at this time, the rotating bushing 221 can drive the locking tongue 24 through the mating member 23 when it rotates. As the latch 24 rotates, the abutment protrusion 232 contacts the bottom surface of the lock groove 111. The latch 24 continues to rotate, and the bottom surface of the lock groove 111 pushes the mating part 23 to rotate through the abutment protrusion 232 until the mating end face 243 of the latch 24 contacts the bottom surface of the lock groove 111. The abutment protrusion 232 no longer protrudes from the mating end face 243. At this time, the mating part 23 rotates to the second position, and the driving protrusion 2221 has disengaged from the mating groove 231. Continue to rotate the handle 21 to the designated position, and then push the handle 21 to retract the driving rod 25 into the rotating sleeve 221 to the storage position. At the same time, the magnetic attraction 291 on the handle 21 attracts the metal part 292, completing the locking of the connecting lock 100. When unlocking is required, first pull the handle 21 to extend the drive rod 25 to the operating position, then rotate the handle 21 in the opposite direction. As the handle 21 drives the drive protrusion 2221 on the rotating bushing 221 to rotate, when the drive protrusion 2221 rotates to the position of the mating groove 231 and contacts one side wall of the mating groove 231, the drive protrusion 2221 continues to rotate, thereby pushing the mating part 23 to rotate from the second position to the first position. The drive protrusion 2221 and the mating groove 231 are fully engaged, thereby driving the bolt 24 to continue rotating to the initial position. During the process of the mating part 23 rotating from the second position to the first position, the abutting protrusion 232 on the mating part 23 protrudes out of the locking end face 243 and abuts against the bottom surface of the lock groove 111 as the mating part 23 rotates, thereby pushing the bolt 24 to rotate in the unlocking direction until the mating groove 231 and the drive protrusion 2221 are fully engaged, and the bolt 24 is driven by the rotating bushing 221 to rotate in the unlocking direction.

[0108] Please refer to the following: Figures 16 to 17In some embodiments, this application also provides a display screen bezel 200. The display screen bezel 200 includes a bezel body and a connection lock 100 as described in any of the above embodiments. The bezel body has opposing first connecting edges 201 and second connecting edges 202. The first connecting component 10 of the connection lock 100 is disposed on the first connecting edge 201, and the second connecting component 20 is disposed on the second connecting edge 202. Thus, when it is necessary to connect two adjacent display screen bezels 200 through the connection lock 100, the first connecting edges 201 and second connecting edges 202 of the two bezel bodies are arranged adjacent to each other. This application takes a rectangular bezel as an example to illustrate the display screen bezel 200. The rectangular bezel has two sets of opposing first connecting edges 201 and second connecting edges 202. Depending on the usage scenario of the display screen bezel 200, the connection lock 100 can be set on one set of opposing first connecting edges 201 and second connecting edges 202 of the rectangular bezel, or the connection lock 100 can be set on both sets of opposing first connecting edges 201 and second connecting edges 202 of the rectangular bezel.

[0109] Please refer to the following: Figures 18 to 19 In some embodiments, the driving component 22 in the connecting lock 100 further includes a driving rod 25, and the driving rod 25 is movably disposed relative to the rotating sleeve 221 in the axial direction. The driving rod 25 has a working position extending out of the rotating sleeve 221 and a storage position retracted into the rotating sleeve 221. A storage groove 203 corresponding to the shape of the handle 21 of the connecting lock 100 can be provided on the second connecting edge 202 of the frame body. When the driving rod 25 is in the storage position, the handle 21 is at least partially embedded in the storage groove 203 in the axial direction of the driving rod 25. By providing a storage groove 203 corresponding to the shape of the handle 21 on the display frame 200, the handle 21 is embedded in the storage groove 203. In this way, on the one hand, the size of the handle 21 protruding from the surface of the display frame 200 can be further reduced, and on the other hand, the rotation of the handle 21 can be limited by the storage groove 203.

[0110] Along the axial direction of the drive rod 25, the handle 21 is at least partially embedded in the receiving groove 203, including the handle 21 being completely embedded in the receiving groove 203 and the handle 21 being partially embedded in the receiving groove. For example... Figure 1 As shown, this application uses the example of the handle 21 being partially embedded in the storage slot 203. When the handle 21 is partially embedded in the storage slot 203, the drive rod 25 can be pulled out by grasping the part of the handle 21 that protrudes from the display screen frame 200. When the handle 21 is fully embedded in the storage slot 203, it can be understood that there are operating notches 204 on both sides of the storage slot 203, as shown in the figure. The user can grasp the handle 21 through the operating notches 204 and then pull out the drive rod 25.

[0111] To enable the mounting of the connecting lock 100 on the display screen bezel 200, since both the latch 24 and the handle 21 need to have certain dimensions, in some embodiments, the second connecting edge 202 can have a first side 2021 for extending the latch 24 of the connecting lock 100 and a second side 2022 for extending the drive rod 25 of the connecting lock 100. In a direction perpendicular to the length direction of the second connecting edge 202, the dimension of the first side 2021 can be H, where H ≥ 30 mm, and the dimension of the second side 2022 can be B, where B ≥ 20 mm. For example... Figure 18 As shown, it can be understood that the dimension H of the first side 2021 in the direction perpendicular to the length direction of the second connecting edge 202 is the height of the second connecting edge 202, and the dimension B of the second side 2022 in the direction perpendicular to the length direction of the second connecting edge 202 is the width of the second connecting edge 202.

[0112] In some embodiments, a display screen is also provided. The display screen includes at least one display screen bezel 200 as described in the above embodiments and a screen body disposed on the display screen bezel 200. The screen body can be a transparent screen or a translucent screen, but is not limited thereto. The display screen includes at least two display screen bezels 200, and the first connecting edge 201 and the second connecting edge 202 of two adjacent display screen bezels 200 are disposed adjacent to each other, so that the first connecting component 10 on the first connecting edge 201 and the second connecting component 20 on the second connecting edge 202 can be locked together.

[0113] The display bezel 200 and display screen provided in this application adopt all the technical solutions of the connection lock 100 in the above embodiments, and therefore have at least all the beneficial effects brought about by the technical solutions of the above embodiments of the connection lock 100, which will not be described in detail here.

[0114] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
