Description

Technical Field

[0001] This application relates to the field of LED display frame locking technology, and in particular to a coaxial linkage locking device and an LED display frame. Background Technology

[0002] The existing method of locking the LED cabinets involves placing a latch on the top of the cabinet and corresponding fixing points on the bottom. When two cabinets are stacked together, the latch on the top is unlocked by pressing an unlock button, pushing the locking mechanism onto the corresponding latch bracket on the bottom of the cabinet to lock it in place. However, this method results in uneven stress distribution at the ends of the cabinet compared to the middle. Another option is to place the latches on either side of the top of the cabinet, which distributes the stress more evenly but takes up space on top. Furthermore, placing two latches on top of the cabinet increases the cost.

[0003] Existing locking devices used on LED display frames have issues such as occupying cabinet space and uneven tension, which can easily damage the LED display frame and affect the display quality of the entire spliced ​​LED display. Summary of the Invention

[0004] Therefore, it is necessary to address the problems of current locking devices occupying cabinet space and uneven tension on LED display frames, and to provide a coaxial linkage locking device and LED display frame.

[0005] In a first aspect, the present invention provides a coaxial linkage locking device, including a locking handle, a linkage shaft, a locking block, a lock body, and a locking rod;

[0006] The linkage shaft is fixed to the latch handle and is arranged parallel to the latch handle; the linkage shaft passes through the lock body, and the lock body is also connected to the latch handle; the locking rod is set on the lock body, the locking rod is connected and fixed to the linkage shaft, and rotates with the linkage shaft; the locking block is used to connect and fix the lock body and the LED display frame.

[0007] In some embodiments, the linkage shaft further includes a ratchet, which is disposed on both sides of the lock body.

[0008] In some embodiments, the lock body includes a first lock body and a second lock body; the first lock body and the second lock body are respectively disposed at both ends of the linkage shaft.

[0009] In some embodiments, the first lock body and the second lock body further include a rotating groove, and the lock rod is disposed in the rotating groove.

[0010] In some embodiments, the locking bar is U-shaped.

[0011] In some embodiments, the latch handle further includes a lock cylinder block fixed to the middle of the latch handle.

[0012] In some embodiments, the lock cylinder block further includes a latch button, a connecting rod, a spring, and a limiting shaft; the limiting shaft passes vertically through the lock cylinder block and is connected to the linkage shaft, and the top protrusion of the limiting shaft protrudes outside the lock cylinder block; the latch button is vertically connected to the limiting shaft through the connecting rod, and the spring is disposed on the connecting rod.

[0013] In some embodiments, the limiting shaft is provided with a limiting hole for the connecting rod to pass through.

[0014] In some embodiments, the connecting rod connecting to the latch button end has a V-shaped structure with gradually increasing width, and the maximum width of the V-shaped structure is 1mm-3mm greater than the width of the limiting hole.

[0015] Secondly, the present invention also provides an LED display frame, including the coaxial linkage locking device described in any of the above embodiments.

[0016] As can be seen from the above, by setting a linkage shaft in the locking device, the number of installation and disassembly operations can be reduced. The locking and unlocking operations of two locks can be performed at one time by rotating the handle up and down, which improves the installation efficiency and the stability and security of the locks. By setting a lock button in the middle of the lock handle, pressing the lock button can unlock the locking rod on the linkage shaft, achieving the unlocking of multiple locks in one operation, saving time and effort. The coaxial linkage locking device provided by the present invention solves the problems of large space occupation and uneven tension. Attached Figure Description

[0024] Please see Figure 1 and Figure 2 , Figure 1 This is an exploded view of a coaxial linkage locking device according to an embodiment of the present invention; Figure 2 This is a schematic diagram of a coaxial linkage locking device according to another embodiment of the present invention; a coaxial linkage locking device includes a locking handle 1, a linkage shaft 2, a locking block 3, a locking body 4, and a locking rod 5; the linkage shaft 2 is fixed on the locking handle 1 and is arranged parallel to the locking handle 1; the linkage shaft 2 passes through the locking body 4, and the locking body 4 is also connected to the locking handle 2; the locking rod 5 is disposed on the locking body 4, and the locking rod 5 is connected and fixed to the linkage shaft 2, and rotates with the linkage shaft 2; the locking block 3 is used to connect and fix the locking body 4 and the LED display frame 14 (e.g., Figure 4 (As shown). The linkage shaft 2 also includes a ratchet 6, which is disposed on both sides of the lock body 4.

[0025] Specifically, a locking device may include a first lock body 4a and a second lock body 4b; the first lock body 4a and the second lock body 4b are respectively located at both ends of the linkage shaft 2. The first and second lock bodies also include rotating grooves, and the locking rod 5 is disposed within the rotating grooves. The locking rod 5 may be, but is not limited to, a U-shaped locking rod; it may also be circular, elliptical, or triangular. This locking device supports linkage, meaning that by grasping the locking handle and moving it forward or backward, both U-shaped locking rods can be simultaneously engaged.

[0026] In some embodiments, the latch handle 1 further includes a lock cylinder block 7, which is fixed to the middle of the latch handle 1. The lock cylinder block 7 also includes a latch button 8, a connecting rod 9, a spring 10, and a limiting shaft 11; the limiting shaft 11 passes vertically through the lock cylinder block 7 and is connected to the linkage shaft 2, with a top protrusion of the limiting shaft 11 protruding outside the lock cylinder block 7 (e.g., ...). Figure 2 (As shown); the locking button 8 and the limiting shaft 11 are vertically connected through the connecting rod 9, and the spring 11 is disposed on the connecting rod 9.

[0027] Please see Figure 3 , Figure 3 This is a front cross-sectional view of a lock cylinder block according to an embodiment of the present invention. A limiting hole 12 is provided on the limiting shaft 11 for the connecting rod 9 to pass through. Specifically, see [reference needed]. Figure 1 and Figure 3 The connecting rod 9 is connected to the locking button 8 in a V-shaped structure with a gradually increasing width.

An LED display frame 14 includes the coaxial linkage locking device described in any of the above embodiments. The LED display frame 14 also includes several locking brackets 13, the number of which is the same as the number of locking rods. The optimal number is two locking rods and two locking brackets. By setting a linkage shaft in the locking device, the number of installation and disassembly operations can be reduced. Turning the handle up and down allows for the locking and unlocking of two locks at once, improving installation efficiency and enhancing the stability and security of the locks. The specific locking operation is as follows: Grasp the locking handle and press the unlock button; then grasp the locking handle and turn it upwards. The U-shaped locking rod will also rotate the handle to the appropriate position; after the U-shaped locking rod aligns with the locking bracket on the upper part of the cabinet, press the locking handle down until the locking button is engaged with the limiting shaft. This completes the splicing and locking between different LED display frames. The unlocking button method is simple and quick, requiring only one operation of the switch button to unlock, improving unlocking efficiency.
