[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model discloses a quick-assembly back frame assembly for LED rental, comprising LED displays 1 arranged vertically in parallel. Multiple support frames are provided on the back of the LED displays 1, and fixed seats 8 are installed on the back of each LED display 1. Multiple connecting components are installed between the support frames and the fixed seats 8. A base 3 is installed at one end of the support frame, and an extension seat 4 is installed at the end of the base 3 away from the LED display 1. A diagonal tie rod 5 is installed between the extension seat 4 and the support frame. A ground beam is installed on the lowest LED display 1.

[0022] In this embodiment, each support frame includes multiple vertical rods 2 and horizontal beams. The horizontal beams are installed between adjacent vertical rods 2. Each vertical rod 2 has a connector 7 installed at one end and a first mating seat installed at the other end. Each base 3 has multiple second mating seats 6 installed. The connectors 7 on the vertical rods 2 are inserted into the first mating seats of adjacent vertical rods 2 and are fixed by oblique pins. The connectors 7 on the lowest vertical rod 2 are inserted into the second mating seats 6 and are fixed by oblique pins.

[0023] In this embodiment, the connecting components all include a connecting main rod 11, a lamp hook 12, and a rotating handle 10. The fixing base 8 is provided with a connecting hole, and the opening of the connecting hole is narrowed inward to form a T-shaped groove 9. One end of the connecting main rod 11 is fixedly connected to the lamp hook 12. The connecting main rod 11 is fixed to the support frame through the lamp hook 12. The other end of the connecting main rod 11 protrudes to form a connector. The connector passes through the T-shaped groove 9 and is inserted into the connecting hole. The rotating handle 10 is installed on the connecting main rod 11.

[0024] The shape of the connector matches the T-slot. After the connector is inserted into the T-slot, it can be rotated to the connecting post so that the connector can be misaligned with the T-slot in the connecting hole to complete the engagement between the fixing seats.

[0025] In this embodiment, the ground beam is provided with multiple fixing holes, and a lock 15 for fixing the ground lock 13 to the LED display screen 1 is installed in the fixing holes. The ground lock 13 is recessed to form multiple mounting grooves, and a first foot cup 14 that can be adjusted up and down is installed in each mounting groove.

[0026] In this embodiment, the ground lock 13 is provided with a connecting groove at the position opposite to the base 3. One end of the base 3 is inserted into the connecting groove. The end of the base 3 facing the ground lock 13 is provided with a first buckle 17. The ground lock 13 is provided with a locking piece 16 at the position opposite to the first buckle 17. The buckle ring on the first buckle 17 is sleeved on the outside of the locking piece 16 and fixes the base 3 and the ground lock 13.

[0027] In this embodiment, one end of the extension seat 4 is inserted into the base 3 and fixed by the second buckle; one end of the diagonal tie rod is installed on the extension seat by a hinge, and the other end is installed on the vertical rod by a hinge and a clamp, so that the diagonal tie rod can be fixed at an angle.

[0028] In this embodiment, both the extension seat 4 and the base 3 are equipped with multiple adjustable second foot cups.

[0029] The back frame assembly consists of a ground beam, a base, an extension seat, a support frame, a connecting component, and a diagonal tie rod. The ground beam has a locking mechanism to fix it to the LED display screen. The left and right ends of the ground beam have adjustable first foot cups to adjust the height according to the ground conditions.

[0030] The base and the ground beam are connected by an interlocking method and locked in place by a second buckle. The base and the extension seat are equipped with a second foot cup to adjust the verticality of the LED display screen and prevent the screen from tilting forward or backward. A set of second mating seats are welded to the base for connecting and fixing the vertical rod.

[0031] The vertical bar has a set of joints for connecting the vertical bars. When locking, a beveled pin is used for locking with a beveled surface.

[0032] The vertical pole and the LED display screen are fixed together by a connecting component. One end of the connecting component is fixed to the vertical pole by a lamp hook, and the other end is inserted into the corresponding T-shaped hole on the cabinet. By rotating the auxiliary handle on the component, a locking state is formed, ensuring that the cabinet and the back frame are firmly fixed. This component also has a telescopic function, which facilitates installation and disassembly.

[0033] The design of the extension seat and diagonal brace makes it easier to achieve a more reasonable weight distribution when setting up a large-scale rental.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto.
