[0046] Furthermore, in the embodiments of this application, "multiple" refers to two or more. Without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples. The terms "first," "second," etc., used herein are used to distinguish different directions, structures, components, etc., and do not represent a chronological order. Additionally, the embodiments described below are merely some embodiments of this application, and not all embodiments.

[0047] A large-size transparent display screen is widely used. This large-size transparent display screen is formed by splicing together multiple smaller transparent display screens. This transparent display screen can be used on the exterior walls of shopping malls to display product floor information, and can also be used as a large screen for display at indoor exhibitions.

[0048] During the assembly of screens, the supporting frames of various small transparent displays are generally connected to each other. The assembled transparent display needs to have a good display effect and a good transparency when not displaying. Therefore, the supporting frame behind the transparent display often uses a high-strength narrow frame, and the connection between the supporting frames is achieved through connecting locks set on the supporting frame.

[0049] Existing connecting locks are complex in structure and relatively large in size. When connecting adjacent support frames, these locks expose a large area, which seriously affects the transparency of the transparent display screen. This results in a poor viewing experience for the transparent display screen and negatively impacts the user experience.

[0050] To address the aforementioned technical issues as much as possible, see [link / reference]. Figures 1 to 6 In one embodiment of this application, a connection lock is provided. The connection lock is applicable to the frame of a display screen, the frame of which includes a plurality of interconnected brackets, the display screen is disposed on the brackets, and the brackets are provided with recessed mounting positions, the width of which is equal to the width of the brackets.

[0051] The aforementioned bracket can be considered as a support frame on a small display screen, and the frame of the display screen can be considered as a large support frame spliced ​​together from multiple small display screen support frames.

[0052] The connecting lock includes: a lock body 2, a lock block 3, and a latch 4. The lock body 2 is mounted on the first mounting position 111 of the first bracket 101, and the lock block 3 is mounted on the second mounting position 112 of the second bracket 102. The lock block 3 can be connected to the second bracket 102 via a connecting bolt 32. The latch 4 is connected to the lock body 2. The lock body 2 is provided with a handle 5, which is driven to connect to or separate from the latch 4. The handle 5 can drive the latch 4 to connect or separate from the lock block 3. The lock body 2 can be driven to move via the handle 5 to achieve the connection or separation of the latch 4 from the lock block 3.

[0053] When the latch 4 is connected to the locking block 3, the first bracket 101 and the second bracket 102 can be locked; when the latch 4 is separated from the locking block 3, the first bracket 101 and the second bracket 102 can be separated from each other.

[0054] In the technical solution of this application, the lock body 2 and the lock block 3 are respectively set in the mounting position of the bracket, which can easily hide the connecting lock. The frame of the bracket can cover the connecting lock. In addition, after using the handle 5, the handle 5 can be rotated relative to the lock body 2 to be stored in the first mounting position 111. When the display screen is a transparent display screen, the connecting lock will not be exposed, and the transparency of the transparent display screen will not be affected. The transparent display screen has a better viewing experience and can bring a better user experience.

[0055] In one embodiment provided in this application, the display screen is connected to the first side of the bracket, while the mounting position is located on the opposite side from the first side. Taking the bracket as a square frame as an example, the display screen is connected to the top side of the bracket, while the mounting position is located on the back side of the bracket.

[0056] In order for the bracket to effectively shield the connecting lock located in the mounting position, in one specific embodiment, the width of the lock body 2 (e.g., Figure 2The direction indicated by the middle arrow X) is less than or equal to the width of the first mounting position 111 (e.g., Figure 2 (In the direction indicated by the middle arrow M), the width of the locking block 3 is less than or equal to the width of the second mounting position 112. Since the lock body 2 and the locking block 3 are respectively located in the mounting positions on one side of the back of the bracket (first bracket 101, second bracket 102), when the width of the lock body 2 and the locking block 3 does not exceed the width of the mounting position, the bracket can effectively cover the lock body 2 and the locking block 3, so that the lock body 2 and the locking block 3 will not be exposed, and the concealment effect is better.

[0057] See Figure 2 , Figure 3 and Figure 6 In one embodiment provided in this application, the height of the lock body 2 is less than or equal to the depth of the recess in the mounting position. The lock body 2 includes a lock seat 21, a latch seat 22, a connecting rod 23, a first rotating shaft 24, and a second rotating shaft 25. The latch seat 22 is connected to the lock seat 21 via the first rotating shaft 24. A connecting rod 23 is provided on each side of the latch seat 22. The connecting rod 23 is connected to the latch seat 22 via the second rotating shaft 25. The latch 4 is connected to the connecting rod 23 on both sides of the latch seat 22.

[0058] Specifically, the lock seat 21 is detachably connected to the first mounting position 111 of the first bracket 101 by fasteners 26 (e.g., screws). The lock seat 21 is arranged along the length of the mounting position, and the width of the lock seat 21 is less than or equal to the width of the mounting position.

[0059] Along the length of the latch seat 22 (e.g.) Figure 2 (In the direction indicated by the middle arrow Y), the latch seat 22 has a first through hole and a second through hole arranged in parallel intervals. A first rotating shaft 24 passes through the first through hole and connects the latch seat 22 to the lock seat 21. A second rotating shaft 25 passes through the second through hole, and a connecting rod 23 is connected to each end of the second rotating shaft 25. The connecting rod 23 is connected to the second rotating shaft 25 by a connecting pin 27. The handle 5 is connected to the side wall of the lock body 2 by a fastening pin 28. The user can drive the latch seat 22 to rotate around the first rotating shaft 24 by the handle 5. As the latch seat 22 rotates around the first rotating shaft 24, the connecting rod 23 will rotate relative to the latch seat 22 around the second rotating shaft 25.

[0060] The latch 4 is located on one side of the latch seat 22. The two ends of the latch 4 are connected to two connecting rods 23 on the second rotating shaft 25 respectively. So when the connecting rod 23 rotates around the second rotating shaft 25 relative to the latch seat 22, the latch 4 will also rotate around the second rotating shaft 25 relative to the latch seat 22.

[0061] Furthermore, the locking seat 22 can rotate around the first pivot 24 to a first position (e.g., Figure 3 (as shown) and the second position (as shown) Figure 2The latch seat 22 rotates between the two positions shown. When the latch seat 22 rotates to the first position, the latch seat 22 drives the latch 4 to connect with the locking block 3. When the latch seat 22 rotates to the second position, the latch seat 22 drives the latch 4 to separate from the locking block 3.

[0062] When the user drives the latch seat 22 to rotate around the first pivot 24 by the handle 5, the end of the latch seat 22 away from the first pivot 24 will gradually rise. Then the connecting rod 23 will rotate around the second pivot 25, and the latch 4 on the connecting rod 23 will rise relative to the locking block 3, so that the latch 4 can separate from the locking block 3.

[0063] In the technical solution provided in this application, the latch 4 and the lock block 3 are connected and separated by using the handle 5 to drive the latch seat 22 to rotate between the first position and the second position. This connection lock structure is simple, easy to operate, and has better reliability.

[0064] See figure Figure 2 , Figure 3 and Figure 6 In one embodiment provided in this application, the latch 4 has a U-shaped structure, with both ends of the latch 4 connected to the connecting rod 23. The latch 4 is located on one side of the lock body 2, and when the latch 4 is connected to the locking block 3, the locking block 3 is located in the U-shaped groove of the latch 4. By placing the locking block 3 between the latch 4 and the lock body 2, the space between the latch 4 and the lock body 2 can be fully utilized. After the latch 4 is connected to the locking block 3, the latch 4 will not exceed the space range of the second mounting position 112, the connection lock will not be exposed, and the concealment effect is good.

[0065] Further, see Figure 5 and Figure 6 The latch 4 is equipped with a first locking element 41 and a second locking element 42 at the end connected to the connecting rod 23. The first locking element 41 and the second locking element 42 are located on both sides of the connecting rod 23. Specifically, the connecting rod 23 has an L-shaped structure, with one arm connected to the second rotating shaft 25 and the other arm connected to the end of the latch 4. The positions of the first locking element 41 and the second locking element 42 on the latch 4 can be adjusted, thereby changing the distance between the latch 4 and the latch seat 22, which is beneficial for adjusting the tightness of the connection between the latch 4 and the locking block 3.

[0066] In one specific embodiment, the end of the latch 4 is provided with a thread, and the first locking member 41 and the second locking member 42 are nuts. By rotating the two nuts respectively, the position of the nuts on the latch 4 can be changed. This adjustment process is simple and convenient.

[0067] See Figure 4 and Figure 6To facilitate a better connection between the locking block 3 and the latch 4, in one embodiment provided in this application, the locking block 3 has a locking groove 31 on the side facing away from the lock body 2. When the latch 4 is connected to the locking block 3, the latch 4 is connected in the locking groove 31. Specifically, the locking block 3 has a left side and a right side facing away from each other. The right side of the locking block 3 faces the latch seat 22, while the left side of the locking block 3 can be considered as the side of the locking block 3 facing away from the lock body 2.

[0068] By setting a lock groove 31 on the lock block 3, it is not only convenient for the latch 4 to connect with the lock block 3, but also makes the connecting lock have better connection stability and tightness.

[0069] See Figures 1 to 5 In one embodiment provided in this application, the lock body 2 and the lock block 3 are arranged along the width direction of the bracket, that is, the width direction of the lock body 2 is in the same direction as the width direction of the bracket, and the length direction of the lock body 2 is in the same direction as the length direction of the mounting position.

[0070] The handle 5 can rotate relative to the lock body 2 between the open and closed states. When the handle 5 is in the open state, the setting direction of the handle 5 is the same as the width direction of the bracket. It can be considered that the setting direction of the handle 5 is perpendicular to the lock body 2, which makes it more convenient for the user to apply force.

[0071] When handle 5 is in the retracted state, its orientation is the same as the length of the bracket. After using handle 5, it can be rotated to switch to the retracted state. In this state, handle 5 is oriented in the same direction as the length of the mounting position, and is retracted into the space of the mounting position, concealed by the bracket and not exposed.

[0072] In addition, by rotating the handle 5, users can switch between the open and closed states, making it easy for them to see the current status of the lock and reducing the risk of accidental operation.

[0073] Furthermore, to ensure stability when the handle 5 is in the retracted state, in one embodiment provided in this application, a limiting groove 12 is provided on the side wall of the first mounting position 111. When the handle 5 is in the retracted state, the end of the handle 5 is accommodated in the limiting groove 12. Specifically, when the handle 5 is switched from the open state to the retracted state, the end of the handle 5 is embedded in the limiting groove 12. This design not only facilitates the complete retraction of the handle 5, but also prevents the handle 5 from rotating automatically, and the locking mechanism is less likely to automatically switch from the locked state to the contact state due to vibration or loosening.

[0074] See Figure 1 , Figure 2 and Figure 6In one embodiment of this application, a display screen is also provided, comprising: a frame, a screen body, and a connecting lock. The frame includes multiple spliced ​​brackets, and the screen body is disposed on one side of the frame. The display screen includes, but is not limited to: a transparent display screen, a liquid crystal display screen, an OLED (Organic Light-Emitting Diode) display screen, a Micro LED display, etc.

[0075] The shape of the bracket includes, but is not limited to, square, triangular, polygonal, and irregular shapes. Taking a square bracket as an example, a square bracket is formed by splicing together multiple frame strips. Each bracket has at least one first mounting position 111 and at least one second mounting position 112. In addition, at least one lock body 2 can be provided in each first mounting position 111, and at least one lock block 3 can be provided in each second mounting position 112.

[0076] After the first bracket 101 and the second bracket 102 are locked together by the connecting lock, in order to make the connection between the first bracket 101 and the second bracket 102 more stable, the two brackets can also be tightly connected by ball screws 6.

[0077] For details on the specific structure of the connection lock, please refer to the description above; it will not be repeated here.

[0078] In summary, the technical solution of this application utilizes a retractable handle to drive the locking seat to rotate, thereby connecting or separating the locking latch from the locking block. This type of connecting lock has a simple structure and is convenient for users to operate. Furthermore, the connecting lock is positioned on a mounting bracket, allowing the handle to be rotated and stored in the mounting position after use. This effectively prevents the connecting lock from being exposed relative to the bracket, ensuring the transparency of the display screen and providing a better viewing experience.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
