[0009] Two locking members are arranged on both sides of the locking wheel respectively; one end of the locking member is used to be connected to the display unit, and the other end is connected to the locking wheel; the locking wheel rotates relative to the display unit so that the locking member has an initial state and a locking state; the locking member can switch between the initial state and the locking state by rotating the locking wheel forward or backward;

[0010] Among them, external force drives the locking wheel to rotate in the forward direction, so that the middle part of the locking piece moves toward the side wall of the locking wheel, so that the locking piece drives the two display units to move toward each other until the locking piece abuts against the outer side wall of the locking wheel, so that the locking piece switches from the initial state to the locking state, thereby realizing the locking of the two adjacent display units.

[0011] In some exemplary embodiments, the locking member comprises a connecting section, a fixing section and a locking section, wherein the connecting section and the fixing section are respectively connected to two ends of the locking section, and both the connecting section and the fixing section are arranged at an angle with the locking section; the connecting section is used to connect to the locking wheel, and the fixing section is used to connect to the display unit; an end of the connecting section and an end of the fixing section are arranged up and down relative to the locking section;

[0012] When the locking member is in the locking state, the locking section abuts against the outer side wall of the locking wheel.

[0013] In some exemplary embodiments, the locking section includes a first section and a second section connected to the first section, the first section is spaced apart from the locking wheel, and the second section can abut against an outer side wall of the locking wheel.

[0014] In some exemplary embodiments, an angle formed between the connecting segment and the locking segment is less than 90°.

DETAILED DESCRIPTION

[0032] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0033] In the description of the present application, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0034] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0035] See also Figure 1 and Figure 2 The present invention provides a display screen 100, including a connection component 20 and at least two display units 10. Two adjacent display units 10 can be quickly and seamlessly spliced ​​through the connection component 20.

[0036] In this embodiment, the length direction of the display unit 10 is consistent with the vertical direction, so that a plurality of display units 10 can be connected and locked in columns through the connecting assembly 20 to form a display screen 100.

[0037] In other embodiments, the length direction of the display unit 10 may also be consistent with the lateral direction, so that a plurality of display units 10 can be connected and locked in rows through the connecting assembly 20 to form a display screen 100 .

[0038] The above arrangement can greatly reduce the workload of on-site installation and achieve the purpose of rapid installation. Moreover, compared with transporting the entire display screen 100, the modular design of the display screen 100 in this application can also effectively save transportation costs, especially when the display screen 100 is large in size, the entire display screen 100 is difficult to enter a small space such as an elevator.

[0039] Each display unit 10 includes at least one display panel 11, and the display panel 11 is used to display images. In the prior art, when connecting adjacent display units 10, at least one display panel 11 on each display unit 10 usually needs to be disassembled, and the disassembly steps are cumbersome, which affects the assembly and disassembly efficiency of the display screen 100. However, the present application provides a connection component 20, which can realize the connection and locking of adjacent display units 10 without disassembling the display panel 11 in the display unit 10.

[0040] Specifically, the connection assembly 20 is disposed outside two adjacent display units 10 , so that it is convenient for an operator to operate the connection assembly 20 without disassembling the display panel 11 of the display unit 10 , thereby effectively improving the assembly and disassembly efficiency of the display screen 100 .

[0041] In some embodiments other than those shown in the drawings of the present application, a recess may be provided at least one corner of the display unit 10 near another display unit 10. For ease of description, the recess on one of the display units 10 is defined as a first recess, and the recess on another adjacent display unit 10 is defined as a second recess. The first recess and the second recess communicate with each other to form an assembly position, and the connection component 20 is arranged in the assembly position, and the depth of the assembly position is not less than the thickness of the connection component 20, so that the surface of the connection component 20 after arrangement does not exceed the surface of the display unit 10. At this time, on the basis of assembling a plurality of display units 10 to form a display screen 100, another display screen 100 may be spliced ​​and arranged to form a display screen 100 of a larger size.

[0042] Furthermore, each display unit 10 is provided with a fixing position 12 , and two ends of the connecting component 20 are respectively connected to the fixing positions 12 of the adjacent display units 10 .

[0043] The fixing position 12 is a hole structure or a groove structure, and the two ends of the connecting component 20 are respectively accommodated in two adjacent display units 10. Exemplarily, the straight line formed by the centers of the fixing positions 12 on the two adjacent display units 10 is arranged parallel to the display surface where the display panel 11 is located, which is conducive to achieving seamless splicing between the two adjacent display units 10. In other embodiments, one of the fixing positions 12 in the two adjacent display units 10 can be arranged close to the box frame in the display unit 10, and the other fixing position 12 can be arranged close to the display panel 11 in the display unit 10, so that the straight line between the two fixing positions 12 is arranged obliquely compared to the display surface where the display panel 11 is located, and this arrangement can also achieve the connection between the two adjacent display units 10.

[0044] See Figure 2 and Figure 3 The connection assembly 20 includes a locking wheel 21 and two locking members 22. The locking wheel 21 is disposed on the outside of two adjacent display units 10. The two locking members 22 are respectively arranged on both sides of the locking wheel 21. One end of the locking member 22 is accommodated in the fixing position 12 of the display unit 10, and the other end of the locking wheel 21 is connected to the locking wheel 21.

[0045] Exemplarily, the two locking members 22 are symmetrically arranged about the center of the locking wheel 21 .

[0046] The locking wheel 21 is used to connect two adjacent display units 10 and can rotate relative to the display unit 10. The locking wheel 21 rotates relative to the display unit 10 so that the locking member 22 has an initial state and a locking state.

[0047] in Figure 4 The locking member 22 is shown in the initial state. Figure 5 The locking member 22 is shown in a locked state. The locking member 22 can be switched between the initial state and the locked state by rotating the locking wheel 21 forward or reversely.

[0048] Specifically, see Figure 4 and Figure 5 , an external force drives the locking wheel 21 to rotate forward, so that the middle part of the locking piece 22 moves toward the side wall of the locking wheel 21, so that the locking piece 22 drives the two display units 10 to move toward each other until the locking piece 22 abuts against the outer side wall of the locking wheel 21, so that the locking piece 22 switches from the initial state to the locking state, thereby connecting and locking the two adjacent display units 10.

[0049] The positive rotation direction refers to the direction in which the middle of the locking member 22 moves toward the side wall of the locking member 22. Specifically in this embodiment, the direction is Figure 5The direction indicated by the arrow is the clockwise direction. In other embodiments, the forward direction may also be the counterclockwise direction, which may be set according to actual needs, as long as the locking member 22 can be switched from the initial state to the locked state.

[0050] See also Figure 6 In some embodiments, a mounting position 211 is provided on the locking wheel 21. The mounting position 211 is used to connect an external tool so that the external tool drives the locking wheel 21 to rotate. The mounting position 211 can be a hole structure that passes through both ends of the locking wheel 21, or a groove structure. The figure takes the mounting position 211 as a hole structure as an example for explanation.

[0051] Exemplarily, the mounting position 211 is a hexagonal hole, so the operator can use a hexagonal tool, such as a hexagonal wrench, a hexagonal screwdriver, etc., to quickly insert it into the mounting position 211 to control the rotation of the locking wheel 21.

[0052] In other embodiments, the mounting position 211 may also be a cross hole, a flat hole, etc. Correspondingly, the user needs to use an external tool that is compatible with the mounting position 211 to ensure that the locking wheel 21 rotates effectively.

[0053] It should be noted that the mounting position 211 is preferably a hole structure or a groove structure compatible with the external standard tools commonly used in the prior art. On the one hand, it can save the cost of customizing non-standard tools; on the other hand, it also allows the operator to easily obtain the tool to control the rotation of the locking wheel 21, which is conducive to improving the disassembly and assembly efficiency of the display screen 100.

[0054] In some embodiments, the mounting position 211 is located at the center of the locking wheel 21 to ensure that the force applied to the locking wheel 21 is evenly distributed, which is beneficial to ensuring the stability of the locking wheel 21 when rotating and ensuring that the two locking members 22 are subjected to balanced force.

[0055] It should be noted that in other embodiments, the locking wheel 21 may also be provided without the installation position 211 , and the user may use external tools such as pliers to clamp the outer side walls on opposite sides of the locking wheel 21 to drive the locking wheel 21 to rotate.

[0056] See also Figure 6 Combined with Figure 3 , assembly holes 212 are provided on both sides of the locking wheel 21 . The ends of the two locking members 22 are respectively accommodated in the two assembly holes 212 , and the ends of the locking members 22 can move in the assembly holes 212 .

[0057] Furthermore, the locking wheel 21 includes a plate body 213 and a cushion block 214 protruding from the plate body 213. Avoidance openings 215 are respectively provided on both sides of the cushion block 214, and the assembly holes 212 are provided on the plate body 213. Each assembly hole 212 is provided correspondingly to an avoidance opening 215. The end of the locking member 22 can be accommodated in the assembly hole 212 through the avoidance opening 215.

[0058] See also Figure 6 Combined with Figure 4 In some embodiments, the side wall of the pad 214 corresponding to the avoidance opening 215 includes a limiting edge 214a and an avoidance edge 214b. The assembly hole 212 can be set at the connection between the limiting edge 214a and the avoidance edge 214b. Among them, the side length of the limiting edge 214a is smaller than the side length of the avoidance edge 214b. The limiting edge 214a is used to prevent the locking member 22 in the connecting assembly 20 from excessive rotation when it is not installed on the display unit 10, which is conducive to the operator to quickly install the two locking members 22 in the fixed position 12 on the display unit 10. When the locking wheel 21 rotates, the avoidance edge 214b of the locking wheel 21 and the locking member 22 move towards each other.

[0059] See also Figure 7 In some embodiments, the connection assembly 20 includes a sealing sheet 23, which is detachably connected to the locking wheel 21. The sealing sheet 23 is used to fix the locking member 22 to the locking wheel 21, so that the various parts in the connection assembly 20 can be pre-assembled into one piece, which is convenient for operators to use directly without on-site assembly affecting the assembly efficiency of the display screen 100.

[0060] Specifically, the sealing piece 23 is arranged on the side of the cushion block 214 away from the plate body 213 , and the sealing piece 23 is arranged corresponding to the assembly hole 212 in the locking wheel 21 to effectively prevent the end of the locking member 22 from falling off from the assembly hole 212 of the locking wheel 21 .

[0061] Specifically in this embodiment, the sealing sheet 23 is provided with a first connection hole 231. The pad 214 in the locking wheel 21 is provided with a second connection hole 214c on the side facing away from the plate body 213. The connecting assembly 20 includes a connecting member (not shown), which is provided with corresponding first connection holes 231 and second connection holes 214c, so as to achieve a stable connection between the sealing sheet 23 and the locking wheel 21. The connecting member can be a screw, a stud, a pin, etc.

[0062] When the connection assembly 20 is installed on the display unit 10, the cover sheet 23 is close to the display unit 10, or the cover sheet 23 directly contacts the surface of the display unit 10. Exemplarily, the first connection hole 231 on the cover sheet 23 is a countersunk hole. The setting of the countersunk hole can completely sink the head of a connecting member such as a screw into the first connection hole 231 of the cover sheet 23, reducing the protruding part, which is beneficial to protecting the surface of the display unit 10 and avoiding the risk of the display unit 10 being scratched.

[0063] Exemplarily, there are two first connection holes 231, which are arranged at opposite sides of the sealing block. Correspondingly, there are also two second connection holes 214c. This arrangement can enhance the connection stability between the sealing sheet 23 and the locking wheel 21.

[0064] In some embodiments, the sealing sheet 23 is a sheet-like structure, and no other hole structures are provided except for the first connection hole 231. When the mounting position 211 of the locking member 22 is a mounting hole structure that passes through both ends of the locking wheel 21, the sealing sheet 23 also seals one end of the mounting position 211, thereby effectively preventing the user from inserting an external tool into the mounting position 211 too far and abutting against the display unit 10, causing excessive wear on the outer surface of the display unit 10 and affecting the appearance of the display unit 10.

[0065] See also Figure 8 Combined with Figure 3 The locking member 22 includes a connecting section 221, a fixing section 223 and a locking section 222. The connecting section 221 and the fixing section 223 are respectively connected to the two ends of the locking section 222, and the connecting section 221 and the fixing section 223 are both arranged at an angle with the locking section 222. The connecting section 221 is used to connect with the locking wheel 21, and the fixing section 223 is used to connect with the fixing position 12 of the display unit 10.

[0066] In some embodiments, arc transitions may be provided at the connections between the connecting segment 221 and the locking segment 222 , and between the fixing segment 223 and the locking segment 222 .

[0067] In some embodiments, an end of the connecting segment 221 and an end of the fixing segment 223 are arranged one above the other with respect to the locking segment 222 .

[0068] Specifically, the locking section 222 can be arranged parallel to the surface of the display unit 10. The connecting section 221 and the locking section 222 are arranged at an angle. The connecting section 221 can extend in a direction away from the display unit 10. Specifically, in the present embodiment, the connecting section 221 extends vertically upward. After the connecting section 221 of the locking member 22 is accommodated in the assembly hole 212 in the locking wheel 21, the connection between the connecting section 221 and the locking section 222, and the end of the locking section 222 close to the connecting section 221 are located in the avoidance opening 215 in the locking wheel 21.

[0069] The fixing section 223 and the locking section 222 are arranged at an angle, and the fixing section 223 extends toward the display unit 10. The fixing section 223 is accommodated in the fixing position 12 of the display unit 10.

[0070] Furthermore, the angle α formed between the fixing section 223 and the locking section 222 is less than 90°, so that when the locking member 22 is switched from the initial state to the locking state driven by the locking wheel 21, the fixing section 223 can be effectively prevented from falling off from the fixing position 12 in the display unit 10, which is beneficial to drive the two adjacent display units 10 to move toward each other and realize the assembly between the two adjacent display units 10.

[0071] It can be understood that the angle between the connecting section 221 and the locking section 222 can also be set to be smaller than 90°.

[0072] Furthermore, the locking section 222 in the locking member 22 includes a first section 222a and a second section 222b connected to the first section 222a. The first section 222a is connected to the connecting section 221, and the first section 222a is spaced apart from the locking wheel 21. The second section 222b is connected to the fixing section 223.

[0073] Exemplarily, the first segment 222a is an arc segment, and the second segment 222b is a straight segment.

[0074] When the locking member 22 switches from the initial state to the locking state, the end of the first section 222a close to the connecting section 221 is located in the avoidance opening 215 on the locking wheel 21 and approaches the avoidance edge 214b of the pad 214 in the locking wheel 21; at the same time, the second section 222b rotates toward the outer wall of the locking wheel 21 until the second section 222b abuts against the outer wall of the locking wheel 21.

[0075] The first section 222a has an avoidance function, which is used to avoid interference with the locking wheel 21, so as to ensure that the second section 222b can smoothly abut against the outer peripheral wall of the locking wheel 21. Therefore, it can be understood that the first section 222a has a variety of configuration forms. In addition to the arc section shown in the figure of this embodiment, the first section 222a can also be configured as a rectangular section, a square section, etc., which can be configured according to actual needs and is not limited here.

[0076] The locking member 22 is an elastic member. In other words, the locking member 22 is made of an elastic material so that the locking member 22 has elastic force. The setting of the elastic member enables the connection assembly 20 to form a self-locking state, thereby connecting and locking two adjacent display units 10.

[0077] Specifically, see Figures 2 to 5Because the connecting section 221 in the locking member 22 is connected to the assembly hole 212 on the locking wheel 21, and the fixing section 223 is tightly accommodated in the fixing position 12 on the display unit 10, when the locking wheel 21 is subjected to an external force and rotates clockwise, the locking section 222 in the locking member 22 rotates about the center between the assembly hole 212 and the fixing position 12, and at the same time drives the two adjacent display units 10 to move closer to each other; until the second section 222b in the locking section 222 abuts against the outer wall of the locking wheel 21. During this process, the connecting section 221 of the locking member 22 bypasses the straight line between the center of the locking wheel 21 and the fixed position 12, and approaches the locking section 222 of the other locking member 22. At this time, the locking member 22 forms an elastic force in the direction from the connecting section 221 toward the fixed section 223, so that the locking wheel 21 has a tendency to continue to rotate clockwise, thereby achieving self-locking of the connecting component 20 and continuously providing force to bring the two adjacent display units 10 closer to each other, thereby ensuring the stability of the splicing of the two adjacent display units 10.

[0078] In addition, the setting of the elastic member can also quickly remove the connecting assembly 20 from the display unit 10. Specifically, the operator uses an external tool to rotate the locking wheel 21 in the opposite direction, that is, counterclockwise in this embodiment, when the connecting section 221 of the locking member 22 returns to the straight line between the center of the locking wheel 21 and the fixed position 12 and close to the side of its own locking section 222, the locking member 22 elastically contracts and can automatically return to the initial state, so that the operator can remove the connecting assembly 20 from the two adjacent display units 10, thereby realizing the separation between the two adjacent display units 10.

[0079] In summary, the connection assembly 20 provided by the present invention has a simple structure, includes fewer parts, and can effectively save production costs. Among them, through the structural setting of the locking wheel 21 and the locking member 22 in the connection assembly 20, the operator only needs to control the rotation of the locking wheel 21 to keep the locking member 22 stably in the locking state to achieve the splicing between two adjacent display units 10. The operation process is convenient and fast, and the operator can operate on the display surface of the display screen 100 without disassembling the display panel 11 in the display unit 10, which can efficiently realize the assembly and disassembly of the display screen 100.

[0080] The above embodiments are merely exemplary descriptions of the structures. The structures in the embodiments are not fixed combination structures. In the absence of structural conflicts, the structures in multiple embodiments can be used in any combination.

[0081] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be embodied in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
