Description

Technical Field

[0001] This utility model relates to the field of display screen installation technology, and in particular to a splicing device and a display frame module. Background Technology

[0002] LED displays are widely used in concerts, exhibitions, sporting events, and theater stages due to their advantages such as vibrant colors, wide dynamic range, and stable and reliable operation. To meet the needs of different scenarios, users often need to splice multiple displays to form larger or specially shaped display devices.

[0003] Traditionally, when splicing displays in a flat surface, screws are used to fix the splicing components to both sides of the display. Then, the splicing components of adjacent displays are fixed together to achieve the splicing of the displays.

[0004] However, the existing splicing components are too cumbersome to install and disassemble with the display screen, requiring each screw to be tightened individually to achieve a secure connection. They also lack convenient docking and positioning structures, often requiring additional tools or auxiliary components to complete installation and locking, making the overall installation operation inconvenient. Utility Model Content

[0005] The purpose of this utility model is to solve the technical problem of inconvenient installation and operation of splicing components in existing display screens.

The pull rod units are fixed to the first straight-screen mechanism and the second straight-screen mechanism. The locking plate units are fixed to opposite sides of the cabinet frames and are correspondingly arranged one-to-one with the pull rod units on the first and second straight-screen mechanisms. The pull rod units are rotatable around their own axes to fix or unlock with the locking plate units, thereby enabling the assembly and disassembly of the first and second straight-screen mechanisms from the cabinet frame.

[0008] In some embodiments of this application, the lever unit further includes a locking member rotatably connected to the handle. The end of the lever near the handle is provided with ratchet teeth that match the locking member. When the first end of the locking member is pressed, causing the second end of the locking member to disengage from the ratchet teeth on the lever, the handle can drive the lever to rotate. When the locking member is released, causing the second end of the locking member to abut against the ratchet teeth on the lever, the rotation of the lever is locked.

[0010] In some embodiments of this application, the first straight screen mechanism further includes a positioning component, which is movably disposed on the first mounting plate and can extend out of the first mounting plate in a first direction; the second mounting plate of the second straight screen mechanism is provided with a positioning hole, and the positioning component can be inserted into the positioning hole when it extends out of the first mounting plate, so that the first straight screen mechanism and the second straight screen mechanism are positioned relative to each other.

[0011] In some embodiments of this application, the positioning component includes a positioning post, a limiting pin, and a connecting screw; the side of the first mounting plate is provided with a limiting hole, the limiting hole having two fixed positions spaced apart along a first direction; the positioning post extends along the first direction, one end of the connecting screw is fixedly connected to the positioning post, and the other end of the connecting screw extends out of the side of the first mounting plate along the limiting hole; the limiting pin is sleeved on the connecting screw and can move axially along the connecting screw, and when the limiting pin moves to insert into the fixed position of the limiting hole, the positioning post is fixed in an extended or retracted state.

[0013] In some embodiments of this application, the first straight screen mechanism further includes a handle, which is fixed to the side of the first mounting plate away from the housing frame.

[0014] This embodiment also provides a display frame module, including: a cabinet frame; and a splicing device as described above, wherein the first straight screen mechanism and the second straight screen mechanism of the splicing device are fixed to opposite sides of the cabinet frame by a quick-release mechanism.

[0015] In some embodiments of this application, the device includes: an LED display screen disposed on the front side of the cabinet frame away from the splicing device; and a power supply box detachably connected to the back side of the cabinet frame to supply power to the LED display screen.

This effectively simplifies the installation and disassembly steps of the first vertical screen mechanism and the second vertical screen mechanism, reduces operational complexity, and avoids the time-consuming installation and disassembly problems caused by using traditional screw fixing methods. This significantly improves the efficiency and flexibility of the display frame module during vertical splicing or maintenance, meeting the user's practical needs for rapid splicing and convenient maintenance.

[0032] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0033] In the description of this application, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back) are merely for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0034] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] The existing splicing components and display screens are cumbersome to install and disassemble, requiring the individual tightening of screws to secure them to the display screen. Furthermore, the lack of convenient docking and positioning structures often necessitates additional tools or auxiliary components for installation and locking, making the overall installation and operation inconvenient. This embodiment provides a new splicing device and display frame module.

[0036] Please see Figures 1 to 11In this embodiment, the display frame module 100 includes a cabinet frame 10 and a splicing device 20. The splicing device 20 can be installed on opposite sides of the cabinet frame 10 so that multiple cabinet frames 10 can be spliced ​​together.

[0037] The cabinet frame 10 has a rectangular structure, and each of its four sides is machined with a beveled surface 11. The beveled surface 11 can abut and fit together when adjacent cabinet frames 10 are vertically spliced, so as to realize the reuse of multiple splicing methods. The splicing device 20 is set on the opposite sides of the cabinet frames 10 for planar splicing of adjacent cabinet frames 10 to form a large-size screen for display.

[0038] Please see Figures 1 to 10 In some embodiments, the splicing device 20 includes a first straight screen mechanism 21, a second straight screen mechanism 22, and a quick-release mechanism 23.

[0039] The first vertical screen mechanism 21 is disposed on one side of the housing frame 10. The second vertical screen mechanism 22 is disposed on the side of the housing frame 10 opposite to the first vertical screen mechanism 21. The first vertical screen mechanism 21 and the second vertical screen mechanism 22 can be detachably connected to splice adjacent housing frames 10 along a first direction.

[0040] The quick-release mechanism 23 includes multiple pull rod units 230 and locking plate units 12 that match the pull rod units 230. The pull rod units 230 are fixed to the first straight-screen mechanism 21 and the second straight-screen mechanism 22; the locking plate units 12 are used to fix to the opposite side of the cabinet frame 10 and are arranged in a one-to-one correspondence with the pull rod units 230 on the first straight-screen mechanism 21 and the second straight-screen mechanism 22. The pull rod units 230 can rotate around their own axis to fix or unlock with the locking plate units 12, so as to realize the assembly and disassembly of the first straight-screen mechanism 21 and the second straight-screen mechanism 22 from the cabinet frame 10.

[0041] Specifically, the first vertical screen mechanism 21 is located at the top of the cabinet frame 10, and the second vertical screen mechanism 22 is located at the bottom of the cabinet frame 10, so that adjacent cabinet frames 10 can be spliced ​​along the first direction, i.e., the vertical direction. The pull rod unit 230 can rotate around its own axis to lock or unlock with the locking plate unit 12, so that the first vertical screen mechanism 21 and the second vertical screen mechanism 22 can be quickly installed and removed from the cabinet frame 10. This effectively simplifies the installation and disassembly steps of the first vertical screen mechanism 21 and the second vertical screen mechanism 22 with the cabinet frame 10, avoids the time-consuming disassembly and assembly problems caused by the traditional screw fixing method, and significantly improves the efficiency and flexibility of the display device in the vertical splicing or maintenance process.

[0042] Please see Figures 2 to 4In some embodiments, the first straight-screen mechanism 21 includes a first mounting plate 211 and a plurality of locking rod adapters 212 passing through the first mounting plate 211, the locking rod adapters 212 being movable along a first direction. The second straight-screen mechanism 22 includes a second mounting plate 221 and a locking plate assembly 223 fixed to the second mounting plate 221. The second mounting plate 221 is provided with an insertion hole 222, which penetrates the second mounting plate 221 along the first direction, and the insertion hole 222 corresponds to the position of the locking rod adapters 212. The locking plate assembly 223 is fixed in the axial extension direction of the insertion hole 222 so as to be able to engage and fix with the locking rod adapters 212 passing through the insertion hole 222.

[0043] Specifically, the first vertical screen mechanism 21 is disposed at the top of the housing frame 10, and includes a first mounting plate 211 for support and positioning, and a locking rod adapter 212 passing through the first mounting plate 211. The first mounting plate 211 provides structural support to ensure that the first vertical screen mechanism 21 can be stably mounted on the housing frame 10. The locking rod adapter 212 is a connecting component that can move along a first direction. When the locking rod adapter 212 extends along the first direction, it forms a plug-in end.

[0044] Conversely, the second vertical screen mechanism 22 is located at the bottom end of the housing frame 10, and includes a second mounting plate 221 for support and positioning, and a locking plate assembly 223 fixed to the second mounting plate 221. The bottom surface of the second mounting plate 221 has an insertion hole 222 that vertically penetrates the second mounting plate 221 along a first direction and corresponds to the movement path of the locking rod adapter 212. When the locking rod adapter 212 on the first vertical screen mechanism 21 extends along the first direction, it can smoothly pass through the insertion hole 222 on the second mounting plate 221 of the other housing frame 10.

[0045] A locking plate assembly 223 is installed on the second mounting plate 221, and the locking plate assembly 223 is installed along the axis of the insertion hole 222. When the locking rod adapter 212 passes through the insertion hole 222, the locking plate assembly 223 will engage with it, thereby achieving a stable lock between the first straight screen mechanism 21 and the second straight screen mechanism 22, and realizing the splicing and fixing of multiple cabinet frames 10 along the first direction.

[0046] In some embodiments, the lock plate assembly 223 may include a lock housing, a lock plate, and a spring. The lock housing serves as a mounting base for the lock plate and the spring, and has a keyhole channel inside. The lock plate is movably disposed within the receiving cavity of the lock housing, while the spring is disposed between the lock plate and the inner wall of the lock housing, with its two ends abutting against the lock plate and the lock housing respectively, thereby providing an elastic restoring force to the lock plate. This allows the lock plate to remain in its initial position, closing the keyhole channel, when not subjected to external force, so as to engage with the annular groove on the inserted lock rod adapter 212, thus fixing it to the lock rod adapter 212.

[0047] Please see Figure 6 In some embodiments, the pull rod unit 230 includes a bushing 231, a pull rod 232, and a handle 233. The pull rod 232 passes through the bushing 231 and is threadedly connected to the inner wall of the bushing 231. One end of the pull rod 232 is fixedly connected to the handle 233, and the other end of the pull rod 232 has a locking portion 2321. The handle 233 can drive the locking portion 2321 to rotate about the axis of the pull rod 232.

[0048] The locking plate unit 12 has a locking hole structure 121, and a protrusion 122 protrudes from the inner wall of the locking hole structure 121. When the engaging part 2321 rotates to the first angle, the engaging part 2321 can be inserted into the locking hole structure 121 along the axial direction of the pull rod 232; when the engaging part 2321 rotates to the second angle, the engaging part 2321 and the protrusion 122 of the locking hole structure 121 engage with each other.

[0049] Specifically, the bushing 231 of the pull rod unit 230 serves as a mounting base for fixing to the mounting plate of the first vertical screen mechanism 21 or the second vertical screen mechanism 22. The inner wall of the bushing 231 is threaded for threaded engagement with the pull rod 232, ensuring that the pull rod 232 can both rotate and move axially within the bushing 231. The pull rod 232 is the connecting component of the pull rod unit 230; one end is fixedly connected to the handle 233, allowing the user to drive the pull rod 232 to rotate by rotating the handle 233. The other end of the pull rod 232 has a locking portion 2321, which is typically a flange structure. The locking portion 2321 has the same shape as the irregular hole formed by the spaced intervals between the two protrusions 122.

[0050] During assembly, the user can push the first straight screen mechanism 21 or the second straight screen mechanism 22 closer to the housing frame 10. This causes the latching part 2321 of the pull rod unit 230 to be aligned at a first angle with the opening of the lock hole structure 121 on the lock plate unit 12, allowing the latching part 2321 to enter the lock plate unit 12 through the irregular hole between the two protrusions 122.

[0051] When the latching part 2321 enters the locking plate unit 12, it rotates to the second angle together with the pull rod 232. The latching part 2321 of the pull rod 232 is misaligned with the opening of the lock hole structure 121, so as to form an abutment fit with the protrusion 122 on the inner wall of the lock hole structure 121 to achieve fixation. At this time, an abutment limiting relationship is formed between the latching part 2321 and the protrusion 122, which can effectively prevent the housing frame 10 from shaking or falling off due to external force during use.

[0052] When disassembly is required, the user simply rotates the lever 232 via the handle 233, causing the latching part 2321 on the lever 232 to rotate to a first angle, aligning the latching part 2321 with the opening of the lock hole structure 121. At this point, the latching part 2321 and the protrusion 122 will not obstruct each other, thus unlocking can be achieved. The entire process requires no additional tools, is simple and quick to operate, and greatly improves the efficiency of on-site installation and disassembly of the first straight-screen mechanism 21 and the second straight-screen mechanism 22.

[0053] Please see Figure 6 In some embodiments, the lever unit 230 further includes a locking member 234. The locking member 234 is rotatably connected to the handle 233, and the end of the lever 232 near the handle 233 has ratchet teeth that match the locking member 234. When the first end of the locking member 234 is pressed, disengaging the second end of the locking member 234 from the ratchet teeth on the lever 232, the handle 233 can drive the lever 232 to rotate; when the locking member 234 is released, causing the second end of the locking member 234 to abut against the ratchet teeth on the lever 232, the rotation of the lever 232 is locked.

[0054] Specifically, the locking element 234 is rotatably connected to the handle 233 via a pin with a torsion spring. Its second end is similar to a pawl, capable of engaging or disengaging with the pull rod 232 in different positions. The end of the pull rod 232 near the handle 233 is machined with ratchet teeth, which are evenly distributed circumferentially and match the second end of the locking element 234, used to limit the rotation of the pull rod 232 when needed.

[0055] It is important to understand that the ratchet teeth on the lever 232 can be either helical or spur teeth. When the ratchet teeth are spur teeth, the rotation of the lever 232 is completely locked when the locking element 234 abuts against the ratchet teeth. When the ratchet teeth are helical teeth with a certain angle of inclination, the lever 232 can rotate in one direction, but its rotation direction is the direction of retraction of the lever 232, and it can only tighten the first vertical screen mechanism 21 and the second vertical screen mechanism 22 to the housing frame 10.

[0056] During use, when the user releases the locking member 234, its second end automatically abuts against the ratchet teeth of the pull rod 232 under the action of the torsion spring. At this time, the rotation of the pull rod 232 is restricted by the meshing relationship between the ratchet teeth and the locking member 234, so that even if the handle 233 is subjected to external force, it cannot drive the pull rod 232 to rotate and disengage from the locking plate unit 12. This effectively prevents the pull rod unit 230 from loosening due to vibration or misoperation, ensuring the safe connection between the first straight screen mechanism 21 and the second straight screen mechanism 22 and the housing frame 10.

[0057] When adjustment or disassembly is required, the user simply presses the first end of the locking member 234 to release the rotation lock of the pull rod 232. This allows the handle 233 to freely rotate the pull rod 232. At this time, the locking part 2321 of the pull rod 232 is rotated to the first angle to disengage from the lock hole structure 121 of the locking plate unit 12, thereby realizing the disassembly and assembly operation.

[0058] By adding the locking element 234 to cooperate with the ratchet teeth, the pull rod 232 has dual limit protection. That is, on the basis of the pull rod 232 being self-locking and anti-loosening through the thread, a mechanical locking mechanism is used to prevent accidental rotation, thereby improving the overall safety and reliability of the pull rod unit 230.

[0059] Please see Figure 3 and Figure 4 In some embodiments, the first straight-screen mechanism 21 further includes a positioning component 24, which is movably disposed on the first mounting plate 211 and can extend out of the first mounting plate 211 in a first direction. The second mounting plate 221 of the second straight-screen mechanism 22 is provided with a positioning hole 224. When the positioning component 24 extends out of the first mounting plate 211, it can be inserted into the positioning hole 224 to position the first straight-screen mechanism 21 and the second straight-screen mechanism 22 relative to each other.

[0060] Specifically, when vertical splicing is required, the user can push the positioning component 24 so that its end extends along the first direction and inserts into the positioning hole 224 opened on the second mounting plate 221 of the second vertical screen mechanism 22, thereby achieving precise positioning between the two mechanisms. The cooperation between the positioning component 24 and the positioning hole 224 simplifies the installation operation, eliminating the need for repeated position adjustments during splicing, significantly improving splicing efficiency, and ensuring the overall consistency of multiple box frames 10 during large-scale splicing.

[0061] Please see Figure 4 In some embodiments, the positioning assembly 24 includes a positioning post 241, a limiting pin 242, and a connecting screw 243. A limiting hole 214 is provided on the side of the first mounting plate 211, the limiting hole 214 having two fixed positions spaced apart along a first direction. The positioning post 241 extends along the first direction, one end of the connecting screw 243 is fixedly connected to the positioning post 241, and the other end of the connecting screw 243 extends out of the side of the first mounting plate 211 along the limiting hole 214. The limiting pin 242 is sleeved on the connecting screw 243 and can move axially along the connecting screw 243. When the limiting pin 242 moves and inserts into the fixed position of the limiting hole 214, the positioning post 241 is fixed in an extended or retracted state.

[0062] Specifically, the positioning post 241 has a strip-shaped or cylindrical structure and extends along the first direction. In its extended state, it can be inserted into the positioning hole 224 of the second straight screen mechanism 22 to achieve precise alignment of the two mounting plates. One end of the connecting screw 243 is fixedly connected to the positioning post 241, forming an L-shaped structure, which allows the positioning post 241 to move inside the first mounting plate 211. The other end of the connecting screw 243 passes through the limiting hole 214 of the first mounting plate 211 and extends to the side of the first mounting plate 211.

[0063] like Figures 7 to 10 As shown, the limiting hole 214 is opened on the side of the first mounting plate 211. The limiting hole 214 has two fixing positions arranged at intervals along the first direction. The two fixing positions correspond to the "fully extended" and "fully retracted" states of the positioning post 241, respectively. When the positioning post 241 is in the extended state, it can be inserted into the positioning hole 224 of the second straight screen mechanism 22 to complete precise alignment. When the positioning post 241 is in the retracted state, it is completely housed in the first mounting plate 211 to avoid interference during transportation or when splicing is not required.

[0064] The limiting pin 242 is sleeved on the connecting screw 243 and can move along the axial direction of the connecting screw 243 to lock and release. When the limiting pin 242 moves out of the limiting hole 214, the user can push the positioning pin 241 to extend or retract; when the limiting pin 242 is reinserted into the fixed position of the limiting hole 214, the positioning pin 241 is fixed.

[0065] The limiting pin 242, through its fixed engagement with the limiting hole 214, ensures the stability of the positioning post 241 under both working conditions, preventing wobbling or accidental retraction of the positioning post 241 during assembly and improving the reliability of assembly positioning. Simultaneously, users can quickly switch the position of the positioning post 241 simply by pulling the limiting pin 242, simplifying operation and significantly reducing preparation time for assembly and installation.

[0066] Please see Figure 4 In some embodiments, the positioning component 24 further includes an elastic element 244. The elastic element 244 is sleeved on the connecting screw 243 and simultaneously abuts against the end of the limiting pin 242 and the connecting screw 243, so as to provide a restoring force after the limiting pin 242 disengages from the limiting hole 214, so that the limiting pin 242 automatically returns to its fixed position and is inserted into the limiting hole 214.

[0067] Specifically, the elastic element 244 is a spring. When the operator pulls the limiting pin 242 out of the fixed position of the limiting hole 214 and changes the state of the positioning post 241, the elastic element 244 generates a thrust through the stored elastic energy, causing the limiting pin 242 to automatically return to the limiting hole 214 along the connecting screw 243 and insert into another fixed position, thereby completing the extension or retraction switching of the positioning post 241, so that the box frame 10 can be quickly and accurately positioned during the splicing process.

[0068] Please see Figure 4 In some embodiments, the first vertical screen mechanism 21 further includes a handle 213, which is fixed to the side of the first mounting plate 211 away from the housing frame 10. Users can directly hold and adjust the position of the housing frame 10 through the handle 213, thereby further improving the ease of operation.

[0069] In some embodiments, the display frame module 100 further includes an LED display screen and a power supply box 30. The LED display screen is disposed on the front side of the frame 10 away from the splicing device 20. The power supply box 30 is detachably connected to the back side of the frame 10 to supply power to the LED display screen.

[0070] Specifically, the LED display screen is a screen unit that displays images. It can be magnetically attached to the cabinet frame 10 to output and display video, images, or text. The power supply box 30 is located on the back side of the cabinet frame 10 and is fixed to the cabinet frame 10 by a detachable connection, facilitating installation and removal. The power supply box 30 contains a circuit module that supplies power to the LED display screen, achieving stable power supply by interfacing with the power interface of the display screen.
