[0039] The present invention will be further described in detail below through specific implementations in conjunction with the accompanying drawings.
[0040] like Figures 1 to 3 As shown, the present application provides a bracket docking lock structure, including a lock head assembly 1, a lock seat 3 and an unlocking member 5.
[0041] The lock assembly 1 is provided at the butt joint end of the first bracket 2. The lock assembly 1 includes a movable latch 11 and a limiter 12. The limiter 12 is sleeved on the movable latch 11 and movably connected to the limiter 12. The limiter 12 is connected to the butt joint end of the first bracket 2 via a fastener such as a fastening screw.
[0042] The lock base 3 is located at the docking end of the second bracket 4. Specifically, the lock base 3 can be a component mounted on the docking end of the second bracket 4, or it can be an integrated structure located at the docking end of the second bracket 4. The lock base 3 includes a stopper slot 31 and a locking slot 32 that are connected in sequence. The movable latch 11 and the stopper 12 both engage with the stopper slot 31. After the movable latch 11 passes through the stopper slot 31, it rotates until it locks with the locking slot 32.
[0043] The unlocking member 5 is sleeved on the outer side of the lock seat 3 . The unlocking member 5 has an unlocking protrusion 51 . The unlocking protrusion 51 extends into the locking groove 32 .
[0044] When the first bracket 2 and the second bracket 4 are docked, the movable latch 11 at the docking end of the first bracket 2 is inserted into the limiting groove 31 at the docking end of the second bracket 4. After the movable latch 11 extends into the locking groove 32, it is rotated until it is misaligned with the limiting groove 31, thereby locking the movable latch 11 on the locking groove 32, thereby achieving the locking of the lock head assembly 1 and the lock base 3, and thus achieving the docking lock of the first bracket 2 and the second bracket 4. When the first bracket 2 and the second bracket 4 are disassembled, the unlocking member 5 is manually rotated, thereby driving the unlocking protrusion 51 to push the movable latch 11 back to align with the limiting groove 31, thereby pulling the movable latch 11 out along the limiting groove 31, thereby achieving the separation of the lock head assembly 1 and the lock base 3, and thus achieving the disassembly and separation of the first bracket 2 and the second bracket 4.
[0045] Compared with traditional docking locks, the bracket docking lock structure of the present application is more convenient to operate and has higher docking and disassembly efficiency.
[0046] like Figures 4 to 6 As shown, in a specific embodiment of the present application, the movable latch 11 includes a pin head 111 and a pin column 112. The diameter of the pin column 112 is smaller than that of the pin head 111. The stopper 12 has a pin hole (not shown), and the pin column 112 is movably inserted into the pin hole. Specifically, the pin column 112 can slide or rotate axially relative to the pin hole.
[0047] like Figures 4 to 6 As shown, in a specific embodiment of the present application, the limiting member 12 has a limiting protrusion 122 extending in the radial direction. When the limiting protrusion 122 cooperates with the limiting groove 31, the limiting protrusion 122 can be used to prevent the limiting member 12 from rotating relative to the docking end of the first bracket 2.
[0048] like Figure 1As shown, in one specific embodiment of the present application, a guide groove 6 extending along a helical line is provided on the pin portion 112, and a boss 7 is provided on the inner wall of the pin hole; alternatively, a guide groove 6 extending along a helical line is provided on the inner wall of the pin hole, and a boss 7 is provided on the pin portion 112. The boss 7 extends into the guide groove 6 and is slidably connected thereto. When the pin portion 112 and the pin hole move axially, the boss 7, guided by the guide groove 6, forces the pin portion 112 to rotate relative to the pin hole, thereby driving the pin head 111 to rotate until it locks with the locking groove 32.
[0049] When the locking cam 32 is engaged, the locking cam 32 is engaged with the locking cam 32 so that the locking cam 32 can be engaged with the locking cam 32, thereby locking the locking cam 32 and locking the locking cam 32 together.
[0050] like Figure 7 As shown, in a specific embodiment of the present application, the limiting groove 31 extends along the axial direction of the lock base 3, and the locking groove 32 is located at the inner end of the limiting groove 31 and extends along the circumferential direction of the lock base 3. When the movable latch 11 passes through the limiting groove 31, it rotates to the locking groove 32, thus forming a misalignment with the limiting groove 31, so that the movable latch 11 can no longer retreat along the limiting groove 31, thereby forming a lock.
[0051] like Figure 6 As shown, in one embodiment of the present application, the pin head 111 has a locking protrusion 113 extending radially. When the pin head 111 rotates to the locking groove 32, the locking protrusion 113 engages with the locking groove 32, forming a lock. When the pin head 111 rotates until the locking protrusion 113 aligns with the limiting groove 31, the movable latch 11 can move axially along the limiting groove 31.
[0052] like Figure 1 As shown, in a specific embodiment of the present application, the lock assembly 1 further includes an elastic member 8, one end of the elastic member 8 being supported against the pin head 111, and the other end of the elastic member 8 being supported against the stopper 12. The elastic member 8 utilizes its elastic potential energy to assist the pin head 111 in returning to its initial position relative to the stopper 12 when exiting the locking groove 32, and also serves to buffer the movement of the movable latch 11.
[0053] like Figure 7 As shown, in a specific embodiment of the present application, the unlocking member 5 includes a docking sleeve 52. An unlocking protrusion 51 is provided on the inner wall of the docking sleeve 52. One end of the docking sleeve 52 is sleeved on the docking end of the second bracket 4, and the docking end of the first bracket 2 can be plugged into the other end of the docking sleeve 52. After the first bracket 2 and the second bracket 4 are docked and locked, the docking sleeve 52 can strengthen the structural strength of the connection position and also align the docking ends of the first bracket 2 and the second bracket 4 coaxially. In addition, when the first bracket 2 and the second bracket 4 are disassembled, the docking sleeve 52 can drive the unlocking protrusion 51 to rotate, and the docking sleeve 52 increases the manual contact area, facilitating manual operation by the operator.
[0054] like Figure 7 As shown, in a specific embodiment of the present application, the locking groove 32 is penetrated along the radial direction of the lock seat 3 so that the unlocking protrusion 51 can extend into the locking groove 32, so that under the drive of the unlocking protrusion 51, the pin head 111 is pushed out of the locking groove 32 to realize the unlocking process.
[0055] This application also provides an LED display screen comprising the bracket docking lock structure described in the above embodiment, a display module, and a mounting bracket. The display module is connected to the mounting bracket, and the bracket docking lock structures are provided at the docking end of the mounting bracket. The number of bracket docking lock structures corresponds to the number of docking ends of the mounting bracket. Because this LED display screen includes the bracket docking lock structure described above, it also possesses the advantages of the aforementioned bracket docking lock structure.
[0056] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
