Description

Technical Field

[0001] This utility model relates to the field of LED technology, and in particular to a quick-release rear connection lock and a carbon fiber LED display cabinet. Background Technology

[0002] As the basic unit of the LED display screen, the ease of its assembly has a significant impact on the installation and maintenance of the entire display screen system.

[0003] Traditional LED display cabinet assembly typically uses connecting plates for fixing, requiring individual alignment, drilling, and screwing—a cumbersome and inefficient process that prolongs the overall system construction cycle. Secondly, due to the limitations of screw connections, disassembling and reinstalling the cabinet becomes extremely difficult when maintenance or replacement of display modules is needed, increasing both maintenance costs and time. Furthermore, over long-term use, connecting plates are prone to loosening screws or fatigue damage, affecting the overall stability of the display and thus impacting its normal operation. Utility Model Content

[0043] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0044] Example 1:

[0045] Reference Figures 1 to 5 This embodiment 1 provides a quick-release lock for the back, including a lock cover 1, a lock body 3, a handle 8, and a mating part 7 that cooperate with each other.

[0046] Specifically, the front side of the lock cover 1 has multiple receiving cavities 12, and its rear side protrudes to form a platform. First locking protrusions 11 are symmetrically arranged on the upper and lower sides of the platform. The front end of the lock body 3 is placed in the receiving cavity 12 for locking with the LED display module. The rear end of the lock body 3 extends from the receiving cavity 12 and is rotatably connected to the end of the handle 8. A mating part 7 is rotatably connected to the handle 8, and the front end of the mating part 7 has a second locking protrusion 71 that engages with the first locking protrusion 11. The handle 8 can be pried upwards or downwards, causing the first locking protrusion 11 and the second locking protrusion 71 to engage, thus stopping the handle 8 from moving.

[0047] See Figure 4 and Figure 6 The front end of the lock body 3 is provided with a lock cavity 31, and a locking step 311 is provided in the lock cavity 31. The locking step 311 is used to cooperate with the locking pin structure 101 described later to realize the locking function. Under the action of external force, the unlocking handle 8, that is, the first locking protrusion 11 and the second locking protrusion 71 are not in the locked state. At this time, the handle 8 can be rotated about the axis of the lock body 3, which drives the lock body 3 to rotate, so that the locking step 311 locks or unlocks the locking pin structure 101.

[0048] The rear end of the lock body 3 is provided with a connecting part 32.

[0049] See Figure 3 and Figure 6 As a feasible solution, the mating part 7 is in the shape of a right angle, with one side of the right angle passing through the middle of the handle 8 and the other side of the right angle covering the back of the handle 8, and the two are connected by an elastic part 4.

[0050] See Figure 3 and Figure 6 The handle 8 has a mounting groove 83 on its back. The front end of the elastic element 4 abuts against the mounting groove 83, and its rear end abuts against the mating part 7. The elastic element 4 provides a rearward thrust to the mating part 7, improving the stability of the engagement between the second latching protrusion 71 of the mating part 7 and the first latching protrusion 11 of the lock cover 1. The elastic element 4 is usually a spring.

[0051] Continue reading Figure 3 and Figure 6 The handle 8 is provided with a first mounting port 81 and a second mounting port 82. The first mounting port 81 is located at the end of the handle 8, and the second mounting port 82 is located in the middle of the handle 8. The mounting groove 83 is located between the first mounting port 81 and the second mounting port 82. The rear end of the connecting part 32 is connected to the first mounting port 81 through a first rotating shaft 5, and the mating part 7 is connected to the second mounting port 82 through a second rotating shaft 6.

[0052] See Figure 3 and Figure 6In practical applications, the back of the lock cover 1 is usually provided with a groove at the position opposite to the first mounting port 81, and a gasket 2 is installed in the groove. A threaded mounting hole 13 is provided in the middle of the lock cover 1.

[0053] In this embodiment 1, four accommodating cavities 12 are provided, symmetrically arranged around the front side of the lock cover 1, so the quick-release lock on the back can connect the four boxes that are put together at the same time.

[0054] Example 2:

[0055] Based on Embodiment 1, the quick-release connection lock on the back also includes a mounting component 9, which can connect the housing and the mounting bracket together.

[0056] See Figure 7 The mounting assembly 9 includes a mounting handle 91, an upper locking member 93, a lower locking member 92, and an adjusting member 94. The upper locking member 93 and the lower locking member 92 are both arc-shaped parts, which are rotatably connected to each other and form an installation space. The free ends of the two parts are movably connected through the adjusting member 94, which is used to adjust the size of the installation space so that the mounting assembly 9 is fixed together with the mounting beam.

[0057] The upper end of the mounting handle 91 is fixedly connected to the lower locking member 92. The lower end of the mounting handle 91 is positioned above the threaded mounting hole 13 and is detachably connected to the lock cover 1 by bolts.

[0058] Example 3:

[0059] Reference Figure 8 This embodiment 3 provides a carbon fiber LED display cabinet, including the aforementioned quick-release back connection lock, and a locking pin structure 101 adapted to the quick-release back connection lock is installed at the right angle on the back of the cabinet. The locking pin structure 101 includes a columnar part and two steps disposed opposite to each other on the outer wall of the columnar part. These two steps are engaged with the locking step 311, and two adjacent cabinets are spliced ​​together by the quick-release back connection lock.
