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 frames are prone to opening after locking due to vibration, wind, or other reasons, resulting in separation of the locked parts and unstable connection. Utility Model Content

[0004] In view of the above problems, this application presents an embodiment. The purpose of this application is to provide a connecting lock and display screen that can make the relative position between the first locking member and the second locking member stable and not easily detached, so as to solve the above problems.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] This application provides a connection lock, including a first locking member 100 and a second locking member 200 used in cooperation with each other.

[0062] The first locking component 100 includes a first mounting base 10, a locking hook 11, and a handle 12. The first mounting base 10 has a first position 101 and a second position 102. The locking hook 11 is rotatably mounted on the first mounting base 10, and the inner side of the hook of the locking hook 11 has a protrusion 111. The handle 12 is driven to connect with the locking hook 11, and when it is in the first position 101 and the second position 102, it locks the position of the locking hook 11.

[0063] Combination Figure 1 See Figures 2 to 4 The second locking component 200 includes a second mounting base 20, on which a splicing block 21 is movably provided, and on the splicing block 21 a first locking pin 22 is provided for use with the locking hook 11.

[0064] Among them, see Figure 1 and Figure 5 After the first locking member 100 and the second locking member 200 are aligned, the handle 12 rotates from the first position 101 to the second position 102, causing the locking hook 11 to rotate synchronously, so that the inner side of the hook of the locking hook 11 hooks the first locking post 22, and the protrusion 111 abuts against the first locking post 22. In this embodiment, the direction of rotation of the handle 12 from the first position 101 to the second position 102 can be set according to different needs, such as... Figure 1 Taking the first position 101 as an example, depending on the different extension directions of the hook head of the locking hook 11, the direction in which the handle 12 rotates from the first position 101 to the second position 102 can be clockwise or counterclockwise. In this embodiment, preferably, the hook head of the locking hook 11 extends in a clockwise direction, and the handle 12 rotates from the first position 101 to the second position 102 in a clockwise direction (e.g., Figure 1 (As indicated by the dashed arrow), the locking hook 11 connects with the first locking pin 22, thus completing the locking action. The handle 12 rotates counterclockwise from the second position 102 to the first position 101, causing the locking hook 11 to separate from the first locking pin 22, thus completing the unlocking action.

[0065] By engaging the protrusion 111 on the locking hook 11 with the first locking pin 22 on the splicing block 21, a two-stage locking mechanism can be achieved between the first locking member 100 and the second locking member 200. Figure 5 Taking the orientation in the middle as an example, see continue. Figure 5The first locking method involves the handle 12 rotating the hook 11 clockwise from the first position 101. During this rotation, the hook 11 gradually engages the first locking pin 22, establishing a connection between them. At this point, the hook 11 and the first locking pin 22 have completed their locking action, thus locking the first locking member 100 and the second locking member 200. To further prevent the hook 11 from separating from the first locking pin 22 due to vibration or other factors, a second locking method is included. In this second locking method, the handle 12 continues to rotate the hook 11 clockwise to the second position 102, where the protrusion 111 on the hook 11 presses against the first locking pin 22, further tightening the hook 11 and securing the relative positions of the hook 11 and the first locking pin 22. The technical solution provided by the embodiments of this application makes the locking hook 11 abut against the first locking pin 22, thereby making the relative position between the first locking member 100 and the second locking member 200 stable and not easy to disengage. It also has the characteristics of stable structure, simple operation and strong practicality.

[0066] The technical solutions provided in the embodiments of this application will be described in further detail below.

[0067] The connection lock provided in this application includes, but is not limited to, connections between displays. See [link / reference] Figure 6 The display screen includes a frame 300, a screen body 400, and connecting locks. The frame 300 includes multiple spliced ​​brackets, and the screen body 400 is located on one side of the frame 300. The shapes of the brackets include, but are not limited to, rectangles, triangles, polygons, and irregular shapes. Taking a square bracket as an example, a square bracket is formed by multiple frame strips spliced ​​together. Connecting locks can be located on the brackets, including but not limited to being connected by fasteners. The first locking member 100 and the second locking member 200 of the connecting lock on the same frame 300 correspond to the second locking member 200 or the first locking member 100 on the adjacent frame 300, respectively.

[0068] For example, the first locking piece 100a on frame 300a and the second locking piece 200a on frame 300b are used in a corresponding manner, and the first locking piece 100b on frame 300b and the second locking piece 200b on frame 300a are used in a corresponding manner with the locking pieces on their adjacent other sides. When the first locking piece 100 and the second locking piece 200 on different frames 300 are locked, the splicing and locking between the two frames 300 is completed.

[0069] See Figure 2 and Figure 3In this embodiment, the splicing block 21 is movably connected to the second mounting base 20, thereby adjusting the relative angle between the splicing block 21 and the second mounting base 20. One purpose of this arrangement is to change the relative angle of the splicing surface of the splicing block 21 by changing the relative angle between the splicing block 21 and the second mounting base 20. The splicing surface of the splicing block 21 is the side of the splicing block 21 facing the first locking member 100, which is the side that abuts with the locking hook 11. By changing the relative angle of the splicing surface of the splicing block 21, the abutment angle between the splicing block 21 and the locking hook 11 can be adjusted, so that the first locking member 100 and the second locking member 200 are angled together and locked.

[0070] For example, see Figure 6 When the connecting lock is used to splice two displays, the first locking piece 100a on frame 300a and the second locking piece 200a on frame 300b are used in a corresponding manner. After the splicing block 21 on the second locking piece 200a on frame 300b is adjusted to the corresponding angle, the first locking piece 100a and the second locking piece 200a are connected at the corresponding angle, so that the angle of the spliced ​​two displays forms the required arc display image.

[0071] Combination Figure 1 and Figure 2 See also Figure 3 In this embodiment, one way to connect the splicing block 21 and the second mounting base 20 is as follows: the second mounting base 20 is provided with a mounting groove 201, and toothed blocks 213 are provided on the groove walls on both sides of the mounting groove 201. The side of the toothed block 213 facing away from the groove wall is an arc-shaped surface, and a first meshing tooth is provided on the arc-shaped surface. The splicing block 21 is disposed in the mounting groove 201. Multiple spring posts 215 are provided on the side of the splicing block 21 facing the bottom of the mounting groove 201. Toothed plates 214 are respectively provided on both sides of the splicing block 213. The toothed plates 214 are arc-shaped plates adapted to the toothed blocks 213. The side of the toothed plates 214 facing the toothed blocks 213 is provided with a second meshing tooth, and the second meshing tooth is engaged with the first meshing tooth. A pressure plate 212 is provided at the opening of the mounting groove 201. The pressure plate 212 is connected to the second mounting base 20 by screws. The pressure plate 212 covers the opening of the mounting groove 201 and can fix the current position of the splicing block 21.

[0072] When the relative position and angle of the splicing block 21 need to be adjusted, loosen the screws fixing the pressure plate 212. Under the action of the spring column 215, the splicing block 21 springs up to a certain height, causing the second meshing tooth to separate from the first meshing tooth. At this time, the splicing block 21 can move back and forth relative to the tooth block 213, that is, adjust the meshing position of the second meshing tooth and the first meshing tooth, so that the splicing block 21 has different tilt angles, or in other words, the side of the splicing block 21 facing the first mounting base 10 has different tilt angles. After the splicing block 21 is adjusted to the required angle, tighten the screws fixing the pressure plate 212, so that the pressure plate 212 presses the splicing block 21, and the second meshing tooth re-meshes with the first meshing tooth, realizing the locking of the splicing block 21 and the tooth block 213, and fixing the current position of the splicing block 21.

[0073] Combination Figure 1 See Figure 7 In some feasible embodiments of this application, the first mounting base 10 has a first mounting cavity 103 opening toward the second mounting base 20, and the locking hook 11 is at least partially disposed within the first mounting cavity 103, and is connected to the handle 12 located outside the first mounting cavity 103 via the portion located within the first mounting cavity 103. See also Figures 2 to 4 The splicing block 21 has a second mounting cavity 211 that opens toward the first mounting base 10, and the first locking pin 22 is disposed in the second mounting cavity 211.

[0074] The locking hook 11 can be installed within the first mounting base 10 through the first mounting cavity 103, and the locking hook 11 can be connected to the outside through the opening of the first mounting cavity 103. There are two ways to set the locking hook 11. In one way, when the locking hook 11 is not connected to the first locking pin 22, such as when the handle 12 is in the first position 101, the locking hook 11 can be completely located within the first mounting cavity 103. In use, it extends out of the first mounting cavity 103 under the action of the handle 12. Having the locking hook 11 completely located within the first mounting cavity 103 prevents it from protruding from the first mounting base 10, thus avoiding it from catching other parts or injuring personnel, and improving safety. Another approach is that when the locking hook 11 is not connected to the first locking pin 22, such as when the handle 12 is in the first position 101, a small part of the hook head of the locking hook 11 is located outside the first mounting cavity 103. During docking, under the premise of ensuring safety, the exposed part of the hook head can be aligned with the opening of the second mounting cavity 211 to improve the accuracy of the locking hook 11 extending into the second mounting cavity 211 and improve docking efficiency.

[0075] To further enhance the clamping effect between the first locking member 100 and the second locking member 200, see [reference needed]. Figures 2 to 4 In this embodiment of the application, the splicing block 21 is also provided with a second locking pin 24, see [link to application]. Figure 5When the inner side of the hook 11 engages with the first locking pin 22, the outer side of the hook 11 abuts against the second locking pin 24. The hook 11 has a protrusion 111. When the protrusion 111 abuts against the first locking pin 22, the hook 11 pulls the first locking pin 22 tight, thereby locking and securing the aligned first locking member 100 and second locking member 200. Simultaneously, when the outer side of the hook 11 abuts against the second locking pin 24, the second locking pin 24 acts as a limiter for the hook 11. Under the force of the rotation of the handle 12, the second locking pin 24 and the first locking pin 22 form a clamping effect on the hook 11, making the abutment between the hook 11 and the first locking pin 22 more stable. At the same time, the second locking pin 24 restricts the locking hook 11 from continuing to rotate, ensuring that the protrusion 111 can accurately abut against the first locking pin 22. This can prevent the protrusion 111 from being misaligned with the first locking pin 22 due to the locking hook 11 not rotating into place or turning too far, thus reducing the clamping effect.

[0076] See also Figures 2 to 4 , Figure 8 To improve the stability of the rotation direction of the locking hook 11, in some feasible embodiments of this application, one implementation is that the splicing block 21 is provided with at least one pair of first ball bearings 23 for use with the locking hook 11, and a first limiting channel 230 for the movement of the locking hook 11 is provided between the two pairs of first ball bearings 23; see also Figure 5 and Figure 9 Along the thickness direction of the hook 11, first guide grooves 112 are respectively provided on both sides of the inner side of the hook 11. In some feasible embodiments of this application, the first guide groove 112 extends from one end near the hook head of the hook 11 to the middle of the hook 11. Of course, the extension length of the first guide groove 112 can also be set according to different needs, and this application does not make a specific limitation.

[0077] See Figure 10 When the handle 12 rotates the locking hook 11 from the first position 101 to the second position 102, the locking hook 11 extends into the first limiting channel 230 and moves, and slides through the first guide groove 112 to connect with the first ball bearing 23. The portion of the first ball bearing 23 that contacts the locking hook 11 has rolling balls 232. When the locking hook 11 rotates with the handle 12, it extends into the first limiting channel 230, and the rolling balls 232 on both sides of the locking hook 11 enter the first guide groove 112, allowing the locking hook 11 and the first ball bearing 23 to slide together, i.e., the locking hook 11 slides between a pair of first ball bearings 23. The pair of first ball bearings 23 can limit the unnecessary displacement of the locking hook 11 in the thickness direction, such as... Figure 10The central position effectively reduces unnecessary displacement of the locking hook 11 in the vertical direction, and also effectively reduces the deformation of the locking hook 11 in the vertical direction, preventing misalignment of the first locking member 100 and the second locking member 200 during docking. For example, when used in splicing display screens, it avoids step differences between the two display screens.

[0078] See also Figure 8 In some feasible embodiments of this application, one implementation of the first ball bearing 23 is as follows: the first ball bearing 23 includes a connecting seat 231, a ball bearing 232, and an elastic connector 233. The ball bearing 232 is connected to the connecting seat 231 via the elastic connector 233. The connecting seat 231 is fixedly installed on the splicing block 21, such as within the second mounting cavity 211. The ball bearing 232 allows for a sliding connection between the first ball bearing 23 and the locking hook 11, while the elastic connector 233 ensures a tighter relative connection between the ball bearing 232 and the locking hook 11, thereby improving the limiting effect of the first ball bearing 23.

[0079] See Figure 9 and Figure 11 To improve the stability of the rotation direction of the locking hook 11, in some feasible embodiments of this application, another implementation is that the first mounting base 10 is provided with at least one pair of second ball bearings 13 for use with the locking hook 11, and a second limiting channel for the movement of the locking hook 11 is provided between the two pairs of second ball bearings 13; along the thickness direction of the locking hook 11, second guide grooves 113 are respectively provided on both sides of the inner side of the hook 11; when the handle 12 drives the locking hook 11 to rotate from the first position 101 to the second position 102, the locking hook 11 extends into the second limiting channel and moves, and slides in connection with the second ball bearings 13 through the second guide grooves 113. In some feasible embodiments of this application, the second guide grooves 113 are located in the region near the root of the locking hook 11. Of course, the position of the second guide grooves 113 can also be set according to different needs, and this application does not make specific limitations.

[0080] See Figure 9 When the handle 12 moves from the first position 101 to the second position 102, it causes the locking hook 11 to rotate (as along...). Figure 1 (Rotating in the direction indicated by the dashed arrow), the locking hook 11 extends into the second limiting channel and moves, and slides through the second guide groove 113 to connect with the second ball bearing 13. The implementation of the second ball bearing 13 is roughly the same as that of the first ball bearing 23. The part of the second ball bearing 13 that contacts the locking hook 11 has rolling balls 232. When the locking hook 11 rotates with the handle 12, the locking hook 11 extends into the second limiting channel, and the rolling balls 232 on both sides of the locking hook 11 enter the second guide groove 113, so that the locking hook 11 and the second ball bearing 13 slide together, that is, the locking hook 11 slides between the two pairs of second ball bearings 13. The two pairs of second ball bearings 13 can limit the displacement of the locking hook 11 in the thickness direction to an unnecessary range, such as... Figure 9 The central position effectively reduces unnecessary displacement of the locking hook 11 in the vertical direction, and also effectively reduces the deformation of the locking hook 11 in the vertical direction, preventing misalignment of the first locking member 100 and the second locking member 200 during docking. For example, when used in splicing display screens, it avoids step differences between the two display screens.

[0081] The implementation of the second bead 13 is largely the same as that of the first bead 23, and can be referenced or learned from the implementation of the first bead 23. Further details will not be provided here. In some feasible embodiments of this application, the connection lock may be provided with only one of the first bead 23 and the second bead 13, or both the first bead 23 and the second bead 13 may be provided.

[0082] See also Figure 9 and Figure 11 In this embodiment, one connection method between the handle 12 and the hook 11 is as follows: the hook 11 is provided with a rotating shaft 114, one end of which is rotatably connected to the first mounting base 10, and the other end is rotatably connected to the handle 12. Another connection method between the rotating shaft 114 and the hook 11 is that the rotating shaft 114 has a connecting plane, making it a non-rotating circular structure along its circumferential direction. The hook 11 has a connecting hole adapted to the connecting plane, and the hook 11 is fitted onto the connecting plane of the rotating shaft 114 through the connecting hole, thereby allowing the rotating shaft 114 to drive the hook 11 to rotate along its circumferential direction. Of course, the rotating shaft 114 and the hook 11 can also be connected in other ways, such as welding or fastener connection. Another connection method between the rotating shaft 114 and the handle 12 is that both the rotating shaft 114 and the handle 12 have through holes, and the rotating shaft enables a rotatable connection between the rotating shaft 114 and the handle 12.

[0083] See also Figure 9 and Figure 11 Located on both sides of the hook 11, an upper sleeve 115 and a lower sleeve 116 are fitted onto the rotating shaft 114. The upper sleeve 115 is located between the handle 12 and the hook 11. Between the hook 11 and the upper sleeve 115, a washer 117 and a spring 118 are fitted onto the rotating shaft 114. The hook 11 is fitted onto the rotating shaft 114, and the upper sleeve 115 and the lower sleeve 116 restrict the hook 11 from moving in the axial direction of the rotating shaft 114. The washer 117 may be made of stainless steel or other materials. A cam structure 121 is provided at the end of the handle 12 connected to the rotating shaft 114. When the handle 12 is pressed down, the cam structure 121 compresses the distance between the upper sleeve 115 and the lower sleeve 116 to compress the spring 118. The spring 118 cooperates with the cam structure 121 to lock the position of the hook 11.

[0084] When it is necessary to rotate the handle 12, rotate the handle 12 upwards to form a certain angle with the first mounting base 10 to facilitate gripping the handle 12. At this time, it can be rotated from the first position 101 to the second position 102, or from the second position 102 to the first position 101. When it is not necessary to rotate the handle 12, press the handle 12 down until the handle 12 is parallel to the first mounting base 10. That is, when the handle 12 is in the pressed state, the cam structure 121 at the end of the handle 12 pulls the rotating shaft 114 tight, and the cam structure 121 compresses the distance between the upper component 115 and the lower component 116, and compresses the spring piece 118. The spring piece 118 cooperates with the cam structure 121 to lock the position of the locking hook 11, thereby locking the position of the handle 12 and the position of the locking hook 11. The setting of the spring piece 118 can further ensure that the cam structure 121 pulls the rotating shaft 114 tight.

[0085] See also Figure 9 and Figure 11 In some feasible embodiments of this application, a limiting member 14 is provided on the first mounting base 10. The limiting member 14 is located outside the hook of the locking hook 11 and close to the root of the locking hook 11. The function of the limiting member 14 is that when the locking hook 11 is not connected to the first locking pin 22, such as when the handle 12 is in the first position 101, the limiting member 14 abuts against the locking hook 11, thereby limiting the range of rotation of the locking hook 11.

[0086] Further, see also Figure 9 and Figure 11 In some feasible embodiments of this application, the first mounting base 10 is provided with a feedback structure 15, which includes a gear 151, a mounting member 152, and a lever 153. The gear 151 rotates synchronously with the locking hook 11. One way for the gear 151 to rotate synchronously with the locking hook 11 is that the gear 151 is connected to a rotating shaft 114, and the gear 151 can rotate synchronously with the rotating shaft 114, thereby achieving synchronous rotation with the locking hook 11. The mounting member 152 is fixedly connected to the first mounting base 10; including but not limited to connection by fasteners, such as screws. One end of the lever 153 is fixedly mounted on the mounting member 152, and the other end meshes with the gear 151.

[0087] When gear 151 rotates synchronously with locking hook 11, gear 151 actuates paddle 153 through its teeth, causing paddle 153 to provide feedback. When shaft 114 rotates, gear 151 rotates, and as paddle 153 shifts from one tooth to another, paddle 153 is actuated, producing a clicking sound and a sticking sensation, thus generating feedback.

[0088] In this embodiment, the specific positions of the first position 101 and the second position 102 are not limited; they can be set according to different needs. In some preferred embodiments, see... Figure 1 and Figure 7 Centered on the connection point between the locking hook 11 and the handle 12, along the length of the first mounting base 10, a first position 101 and a second position 102 are respectively located on both sides of the center. When the handle 12 switches between the first position 101 and the second position 102, it can realize the connection and separation between the locking hook 11 and the first locking pin 22. After the corresponding action is completed, the length direction of the handle 12 is the same as the length direction of the first mounting base 10, so that the handle 12 does not occupy the space in the width direction of the first mounting base 10, that is, it does not protrude from the first mounting base 10 along the width direction of the first mounting base 10, and thus does not affect the second mounting base 20 on one side and the frame 300 on the other side of the width direction of the first mounting base 10.

[0089] Furthermore, in some possible embodiments of this application, see also [link to relevant documentation]. Figure 7 To facilitate the storage of the handle 12, receiving slots for accommodating the handle 12 are provided at the first position 101 and the second position 102, respectively. After the corresponding action is completed, the handle 12 can be stored in the receiving slot, so that the handle 12 will not protrude from the first mounting base 10 in the height direction, further reducing the space occupied by the first mounting base 10.

[0090] See Figure 1 and Figure 6 Based on the above embodiments, one embodiment of this application also provides a display screen, which includes: a frame 300, a screen body 400, and a connecting lock. The frame 300 includes multiple spliced ​​and connected brackets, and the screen body 400 is disposed on one side of the frame 300. 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 MicroLED display, etc.

[0091] The shape of the bracket includes, but is not limited to, rectangles, triangles, polygons, and irregular shapes. Taking a square bracket as an example, a square bracket is formed by multiple frame strips spliced ​​together. Connecting locks can be installed on the bracket, including but not limited to connections via fasteners. The first locking member 100 and the second locking member 200 of the connecting lock on the same frame 300 correspond to the second locking member 200 or the first locking member 100 on adjacent frames 300, respectively. For the specific structure of the connecting lock, please refer to the implementation method of the connecting lock described in the above embodiments; it will not be repeated here.

[0092] In summary, the technical solution provided by the embodiments of this application can achieve two-stage locking between the lock hook 11 and the first lock pin 22 by cooperating with the protrusion 111 on the lock hook 11. This makes the relative position between the first lock member 10 and the second lock member 20 stable and not easy to disengage. It also has the characteristics of stable structure, simple operation and strong practicality.

[0093] 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.
