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 small-sized displays after locking, resulting in shaking and step differences. Utility Model Content

[0020] 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.

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.

[0022] 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.

[0023] 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 in the figure. This application provides a connection lock, including: a first locking member 100 and a second locking member 200 that cooperate with each other.

[0024] Combination Figure 1 See Figures 2 to 4 The first locking component 100 includes: a handle 10, a locking rod 20, a locking sleeve 30, a fixing seat 40, and a spring component 50; one end of the locking rod 20 is drivenly connected to the handle 10, and the other end is provided with a locking limit pin 21; the locking sleeve 30 is sleeved on the outside of the locking rod 20 and is movably limitedly connected to both the handle 10 and the locking rod 20; the fixing seat 40 has a mounting hole 41, the locking rod 20 and the locking sleeve 30 are movably disposed in the mounting hole 41, and the fixing seat 40 is limitedly connected to the locking sleeve 30; the spring component 50 is disposed between the handle 10 and the fixing seat 40; the second locking component 200 is located on the side where the locking limit pin 21 is located, and the second locking component 200 has a locking hole 201 for use with the locking limit pin 21; When a locking operation is required, the handle 10 rotates from the first position to the second position along a first direction, which can align the locking limit pin 21 with the lock hole 201. In this embodiment, the first direction can be set according to different needs; the first direction can be clockwise or counterclockwise. The first position is defined as 0 degrees. Rotating the handle 10 from the first position to the second position means that the handle 10 has rotated by a certain angle. Rotating the handle 10 to the second position means that the handle 10 has rotated relative to the second position by N degrees. The value of N can be set according to different needs; for example, the value of N is 90 degrees.

[0025] After the locking limit pin 21 is aligned with the lock hole 201, the handle 10 moves in the second direction, compresses the spring 50, and drives the locking rod 20 and the lock sleeve 30 to move synchronously, so that the locking limit pin 21 extends into the lock hole 201. In this application, the second direction refers to the direction from the first locking member 100 to the second locking member 200. The purpose of the handle 10 moving the locking rod 20 and the lock sleeve 30 in the second direction is to extend the locking limit pin 21 on the locking rod 20 into the lock hole 201.

[0026] Then, rotating the handle 10 in the opposite direction of the first direction can cause the locking limit pin 21 to be misaligned with the lock hole 201, so that the locking limit pin 21 is locked with the second lock 200, thereby completing the locking between the first lock 100 and the second lock 200.

[0027] The technical solution provided in this application embodiment enables the connection of two splicing components (such as two displays) through the first locking member 100 and the second locking member 200. The locking rod 20 engages with the locking hole 201 through the locking limit pin 21, and the locking rod 20 is pulled away from the second locking member 200 by the spring member 50, so that the locking rod 20 tightens the second locking member 200, thereby ensuring the relative position between the first locking member 100 and the second locking member 200, thus completing the splicing between the two splicing components (such as two displays), and 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.

[0028] The technical solutions provided in the embodiments of this application will be described in further detail below.

[0029] The connecting lock provided in this application embodiment can be used for splicing two splicing components, including but not limited to connecting 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 two displays need to be spliced ​​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.

[0030] See also Figures 1 to 5 In some feasible embodiments of this application, the way the handle 10 rotates from a first position to a second position along a first direction to align the locking limit pin 21 with the lock hole 201 is as follows: the lock sleeve 30 is provided with a first sliding groove 31 extending along the circumferential direction of the lock sleeve 30; at one end of the locking rod 20 corresponding to the position of the first sliding groove 31, a second sliding groove 22 is provided that extends spirally along the axial direction of the locking rod 20, and the length of the first sliding groove 31 is greater than the length of the second sliding groove 22 along the circumferential direction of the lock sleeve 30; the handle 10 is provided with a first limiting pin 11, which passes through the first sliding groove 31 and extends into the second sliding groove 22. To make the operation of the handle 10 driving the locking rod 20 more stable, in some feasible embodiments of this application, there are two of each of the first sliding groove 31, the second sliding groove 22, and the first limiting pin 11, and they are all arranged opposite each other.

[0031] When the handle 10 is rotated, the first limiting pin 11 can drive the locking rod 20 to move relative to the locking sleeve 30 along the extending direction of the first sliding groove 31 and the second sliding groove 22, thereby aligning the locking limiting pin 21 with the lock hole 201. In one implementation, when the handle 10 is rotated from the first position, the first limiting pin 11, in conjunction with the first sliding groove 31 and the second sliding groove 22, drives the locking rod 20 to move a preset distance along the second direction. For example, when the handle 10 is rotated 45 degrees from the first position along the first direction, the handle 10 drives the first limiting pin 11 to rotate synchronously, causing the first limiting pin 11 to slide in the first sliding groove 31 and the second sliding groove 22. Since the second sliding groove 22 is spiral-shaped, the locking rod 20 moves relative to the locking sleeve 30 along the second direction, i.e., downwards. The downward distance of the locking rod 20 is the length of the second sliding groove 22 along the axial direction of the locking rod 20, i.e., the preset distance.

[0032] After the handle 10 moves the locking rod 20 a preset distance via the first limiting pin 11, the handle 10 continues to rotate to the second position, for example, it rotates 45 degrees along the first direction. That is, the handle 10 rotates from the first position to the second position, a total of 90 degrees. The first limiting pin 11 drives the locking rod 20 to rotate synchronously along the first direction so that the locking limiting pin 21 is aligned with the lock hole 201.

[0033] See also Figures 1 to 5 In one embodiment of this application, the first limiting pin 11 is provided on the handle 10 in such a way that the first limiting pin 11 is provided with a threaded structure, the handle 10 is provided with a first threaded hole 12, the first limiting pin 11 is threadedly connected and fixed to the first threaded hole 12, and a part of the first limiting pin 11 passes through the first slide groove 31 and extends into the second slide groove 22.

[0034] Further, see also Figures 1 to 5 In some feasible embodiments of this application, the lock sleeve 30 is provided with a third sliding groove 32, which includes a vertical section 321 extending along the axial direction of the lock sleeve 30 and a horizontal section 322 extending along the circumferential direction of the lock sleeve 30; the lock rod 20 is provided with a second limiting pin 23 at a position corresponding to the third sliding groove 32, which is used in conjunction with the third sliding groove 32; when the handle 10 is rotated from the first position, that is, when the handle 10 moves the lock rod 20 a preset distance along the second direction through the first limiting pin 11 in conjunction with the first sliding groove 31 and the second sliding groove 22, the handle 10 also moves the second limiting pin 23 along the vertical section 321 to the horizontal section 322; when the handle 10 continues to rotate to the second position, that is, when the handle 10 moves the lock rod 20 synchronously along the first direction through the first limiting pin 11, the handle 10 also moves the second limiting pin 23 along the horizontal section 322.

[0035] By limiting the movement of the locking rod 20 relative to the locking sleeve 30 through the cooperation between the second limiting pin 23 and the third sliding groove 32, the movement trajectory of the locking rod 20 relative to the locking sleeve 30 can be better limited, ensuring the accuracy of the movement of the locking rod 20, thereby ensuring that the locking limiting pin 21 on the locking rod 20 and the lock hole 201 on the second lock 200 are more accurately aligned.

[0036] Meanwhile, the cooperation between the second limiting pin 23 and the third sliding groove 32 allows for better locking between the locking limiting pin 21 and the second locking member 200. When the locking limiting pin 21 is aligned with the lock hole 201, and the handle 10 drives the locking limiting pin 21 into the lock hole 201, the handle 10 can rotate in the opposite direction of the first direction, thereby causing the locking limiting pin 21 to be misaligned with the lock hole 201, thus locking the locking limiting pin 21 with the second locking member 200. During this process, when the handle 10 rotates in the opposite direction of the first direction, such as rotating 90 degrees in the opposite direction, the handle 10 rotates back to the first position. The handle 10 drives the locking rod 20 to rotate synchronously, so that the second limit pin 23 rotates along the horizontal section 322 of the third slide groove 32 to the vertical section 321. At this time, based on the restoring force of the spring 50, the locking force between the locking limit pin 21 and the second locking member 200 is increased, making the locking limit pin 21 and the second locking member 200 more stable, so that the first locking member 100 and the second locking member 200 do not wobble after being connected, ensuring that there is no step difference between the two splicing parts (such as two displays) after splicing.

[0037] Combination Figure 2 and Figure 3 See Figure 4 To prevent radial wobbling of the locking rod 20 relative to the locking sleeve 30, in some feasible embodiments of this application, the diameter of the area on the locking rod 20 where at least the second sliding groove 22 and the second limiting pin 23 are provided matches the inner diameter of the locking sleeve 30. With this arrangement, after the locking rod 20 and the locking sleeve 30 are engaged, while ensuring that the locking rod 20 can rotate circumferentially and move axially within the locking sleeve 30, the radial distance between the locking rod 20 and the locking sleeve 30 can be relatively small, reducing the relative displacement between them in the radial direction. This prevents radial wobbling of the locking rod 20 relative to the locking sleeve 30 and ensures more stable circumferential rotation and axial movement of the locking rod 20 within the locking sleeve 30. Simultaneously, with this arrangement, the diameter of other areas of the locking rod 20 can be smaller than the inner diameter of the locking sleeve 30, thereby reducing the weight of the locking rod 20 and consequently reducing the overall weight of the connecting lock.

[0038] Another possible way to prevent radial swaying of the locking rod 20 relative to the locking sleeve 30 is to provide a support protrusion 24 on the locking rod 20, the diameter of which matches the inner diameter of the locking sleeve 30. By using the support protrusion 24, the radial distance between the locking rod 20 and the locking sleeve 30 is kept relatively small, reducing the relative displacement between them in the radial direction. This prevents radial swaying of the locking rod 20 relative to the locking sleeve 30 and ensures greater stability for the locking rod 20's circumferential rotation and axial movement within the locking sleeve 30. The support protrusion 24 can be provided separately or simultaneously as described above; this embodiment does not impose specific limitations.

[0039] In this embodiment, after the locking limit pin 21 is aligned with the lock hole 201, the handle 10 moves in the second direction, compressing the spring 50 and causing the locking rod 20 and the locking sleeve 30 to move synchronously, so that the locking limit pin 21 extends into the lock hole 201. To further limit the movement trajectory and range between the locking sleeve 30 and the fixed base 40, please refer to [reference needed]. Figure 2 and Figure 3 The lock sleeve 30 is provided with a fourth sliding groove 33 extending along the axial direction of the lock sleeve 30; the fixed base 40 is provided with a third limiting pin 42, which extends into the fourth sliding groove 33; wherein, when the handle 10 moves along the second direction, the third limiting pin 42 cooperates with the fourth sliding groove 33, so that the lock sleeve 30 moves along the extension direction of the fourth sliding groove 33 and limits the moving distance of the lock sleeve 30.

[0040] After the locking limit pin 21 is aligned with the lock hole 201, the handle 10 moves in the second direction, that is, the handle 10 drives the locking rod 20 and the locking sleeve 30 to move in the direction of the second locking member 200, and the locking limit pin 21 is inserted into the lock hole 201. The third limit pin 42 slides in the fourth slide groove 33, which restricts the sliding trajectory of the locking sleeve 30 and the locking rod 20 relative to the fixed seat 40, and also restricts the maximum displacement of the locking sleeve 30 and the locking rod 20 relative to the fixed member in the second direction.

[0041] See Figure 1 and Figure 2 In one embodiment of this application, the fixing base 40 may include a first base 401 and a second base 402 disposed on the first base 401. The first base 401 is used to connect to the frame of the display screen, for example, the first base 401 is fixedly connected to the frame by screws. The second base 402 is also fixedly connected to the first base 401 by screws. The first base 401 and the second base 402 are respectively provided with mounting holes 41a and 41b, which are interconnected to form the mounting hole 41 of the fixing base 40. One end of the spring member 50 abuts against the second base 402, and the other end of the spring member 50 abuts against the handle 10 to pull the locking rod 20 away from the locking hole 201, so that the locking rod 20 tightens the second locking member 200 and prevents the two spliced ​​display screens from shaking.

[0042] The second seat 402 is provided with a third limiting pin 42. (See also...) Figure 2 In one embodiment of this application, the third limiting pin 42 is provided on the second seat 402 in such a way that the third limiting pin 42 is provided with a threaded structure and the second seat 402 is provided with a second threaded hole 403. After the third limiting pin 42 is threadedly connected and fixed to the second threaded hole 403, a part of the third limiting pin 42 extends into the fourth sliding groove 33 to limit the sliding trajectory of the locking sleeve 30 relative to the fixed seat 40.

[0043] See Figures 1 to 3 , Figure 5 In some feasible embodiments of this application, to lock the position of the locking rod 20 when the handle 10 is in the first position, the handle 10 is also provided with a locking member 60. One way to set the locking member 60 is that the handle 10, the locking rod 20, and the locking sleeve 30 are connected by having a receiving groove on the handle 10, with one end of the locking rod 20 and one end of the locking sleeve 30 disposed in the receiving groove. The locking member 60 is rotatably provided on the handle 10. When the handle 10 is in the first position, the locking end 61 of the locking member 60 can extend into the receiving groove and connect with the locking sleeve 30 to lock the relative position between the locking sleeve 30 and the locking rod 20.

[0044] After the locking end 61 of the locking member 60 is connected to the lock sleeve 30, the locking member 60 and the lock sleeve 30 cannot rotate in the circumferential direction of the lock sleeve 30. Therefore, the handle 10 cannot rotate relative to the lock sleeve 30, thus limiting the relative movement between the locking rod 20 and the lock sleeve 30. When the handle 10 rotates back to the first position in the opposite direction of the first direction, the locking limit pin 21 is locked to the second locking member 200. At this time, the locking end 61 of the locking member 60 extends into the receiving groove and connects to the lock sleeve 30, which can lock the relative position of the locking rod 20 to ensure the stability of the locking between the locking limit pin 21 and the second locking member 200.

[0045] See also Figure 2 and Figure 5 In one embodiment of this application, the locking member 60 may be implemented as follows: the locking member 60 includes a button 62, a connecting shaft 63, and a torsion spring 64; the side of the handle 10 is provided with an opening 13 that communicates with the receiving groove, the connecting shaft 63 is disposed at the opening 13, the button 62 is rotatably disposed on the connecting shaft 63, the torsion spring 64 is sleeved on the connecting shaft 63, and the two force-applying ends of the torsion spring 64 are respectively connected to the button 62 and the handle 10; the locking sleeve 30 is provided with a first limiting groove 34 at one end of the receiving groove, and when the handle 10 is in the first position, the locking end 61 on the button 62 is connected to the first limiting groove 34.

[0046] When locking is required, first press button 62 to disengage the locking end 61 on button 62 from the first limit groove 34 (see...). Figure 5 This unlocks the locking member 60 from the locking sleeve 30. When the locking limit pin 21 extends into the lock hole 201, the handle 10 is rotated back to the first position in the opposite direction of the first direction, locking the locking limit pin 21 to the second locking member 200. Simultaneously, the locking end 61 of the locking member 60 connects to the first limiting groove 34 to lock the relative position of the locking sleeve 30 (i.e., the locking rod 20), ensuring the stability of the lock between the locking limit pin 21 and the second locking member 200.

[0047] Further, see also Figure 5 The locking sleeve 30 is also provided with a second limiting groove 35 on one end of the receiving groove. When the handle 10 is rotated to the second position, the locking end 61 of the locking member 60 is connected to the second limiting groove 35 to limit the handle 10 from continuing to rotate in the first direction. By limiting the second limiting groove 35, the rotation range of the handle 10 in the first direction can be limited. When the handle 10 is rotated to the second position, it cannot continue to rotate. At this time, the locking limiting pin 21 and the lock hole 201 are accurately aligned. If the handle 10 continues to rotate, it will cause the locking limiting pin 21 and the lock hole 201 to misalign, making it impossible to complete the insertion action and affecting the subsequent locking action.

[0048] Meanwhile, based on the torsion spring 64 and button 62 on the locking member 60, the second limiting groove 35 can also serve as a prompt. When the locking end 61 is separated from the first limiting member, the locking end 61 will move against the lock sleeve 30 due to the rotation of the handle 10 and the force of the torsion spring 64. When the locking end 61 moves to the position of the second limiting groove 35, the force of the locking end 61 against the lock sleeve 30 will lose support due to the appearance of the second limiting groove 35. The locking end 61 will impact and enter the second limiting groove 35. When the locking end 61 is stuck in the second limiting groove 35, a "click" sound will be made, indicating that the handle 10 has been rotated to the second position, that is, the locking limiting pin 21 is aligned with the lock hole 201.

[0049] Furthermore, to make the rotation of the handle 10 smoother, the second limiting groove 35 and the locking end 61 are in a one-way rotational engagement; when the handle 10 rotates in the opposite direction of the first direction, the handle 10 can drive the locking end 61 to separate from the second limiting groove 35. In this configuration, after the locking limiting pin 21 is inserted into the lock hole 201, when the handle 10 is rotated in the opposite direction of the first direction, it is not necessary to press the button 62 to separate the locking end 61 from the second limiting groove 35. The handle 10 can smoothly rotate back to the first position, so that the locking limiting pin 21 is locked with the second locking member 200, and the locking end 61 of the locking member 60 is connected to the first limiting groove 34 to lock the relative position of the lock sleeve 30, i.e., the locking rod 20.

[0050] 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.

[0051] 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 displays, 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.

[0052] In summary, the technical solution provided in this application embodiment enables the connection of two splicing components (such as two displays) through the first locking member 100 and the second locking member 200. The locking rod 20 engages with the locking hole 201 through the locking limit pin 21, and the spring member 50 pulls the locking rod 20 away from the second locking member 200, so that the locking rod 20 tightens the second locking member 200, thereby ensuring the relative position between the first locking member 100 and the second locking member 200, thus completing the splicing between the two splicing components (such as two displays), and 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.

[0053] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
