Description

Technical Field

[0001] This utility model relates to the field of projection screen technology, and in particular to an integrated support device for LED projection screens. Background Technology

[0002] LED projection screens are devices that use LEDs as a light source and combine optical and display technologies to project images or videos onto a screen. They emit light through semiconductor materials, eliminating the need for high-voltage excitation of traditional bulbs. They are characterized by energy saving, long lifespan, and vibrant colors, and are widely used in home entertainment, business presentations, education and training, and other fields. However, current projection screens are difficult to position and install; they are easily damaged by wind when unfolded, resulting in poor display effects; and they are also difficult to repair.

[0003] To address the aforementioned issues, existing patent (CN216485966U) discloses a projection screen for exhibition and display that is easy to position and install. The screen includes: an outer cover with an internal electric rewind shaft connected to the outer side of the shaft; limiting grooves symmetrically distributed about the vertical center line of the cover at both ends; and mounting brackets connected to the limiting grooves, with supports fixed to the upper and lower sides of both brackets, each bracket having positioning holes at both ends. This projection screen facilitates quick positioning and installation by pressing the limiting grooves at both ends of the outer cover against the mounting brackets. The "C"-shaped mounting brackets allow for rapid positioning and installation of the outer cover. The electric rewind shaft lowers and unfolds the projection screen. A connecting sleeve moves along a "T"-shaped guide rail via a sliding groove to prevent the projection screen from being blown away by wind. A pull ring allows the outer cover to be detached from the mounting brackets, facilitating disassembly and maintenance of the projection screen.

[0004] However, in the aforementioned existing technologies, the projection screen needs to be installed on a wall and then fixed with bolts, which limits the installation and use of the projection screen. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated bracket device for LED projection screens, which solves the technical problem that in the prior art, projection screens need to be installed on a wall and fixed with bolts, resulting in limitations in the installation and use of projection screens.

[0006] To achieve the above objectives, this utility model employs an integrated LED projection screen support device, comprising a base and an assembly mechanism. The assembly mechanism includes a mounting frame, an assembly component, and a projection screen body. The mounting frame is fixedly connected to the base and located above the base. The assembly component includes a connecting rod, mounting bolts, an adjusting component, a support frame, an insertion block, and a crossbar. The connecting rod is detachably connected to the mounting frame and located above the mounting frame. The mounting bolts are threadedly connected to the mounting frame and located outside the mounting frame, passing through both the mounting frame and the connecting rod. The adjusting component is slidably connected to the connecting rod and located above the connecting rod. The support frame is fixedly connected to the adjusting component and located above the adjusting component. The insertion block is fixedly connected to the support frame and located above the support frame. The crossbar is detachably connected to the insertion block and located outside the insertion block. The projection screen body is detachably connected to the crossbar and located outside the crossbar.

[0007] The adjusting component includes an adjusting rod and a locking bolt. The adjusting rod is slidably connected to the connecting rod and is located above the connecting rod. The locking bolt is threadedly connected to the connecting rod and is located outside the connecting rod. The locking bolt passes through the connecting rod and the adjusting rod.

[0008] The assembly components also include support members.

[0009] The support includes a fixed base and a support rod. The fixed base is detachably connected to the base and is located outside the mounting bolt. One end of the support rod is rotatably connected to the fixed base and is located outside the fixed base.

[0010] The support component further includes a sleeve and a connecting seat. The sleeve is fixedly connected to the support rod and is located on the outside of the support rod. The connecting seat is rotatably connected to the other end of the support rod and is located below the locking bolt.

[0011] The assembly component also includes a counterweight and an anti-slip pad. The counterweight is detachably connected to the base and located inside the base. The anti-slip pad is fixedly connected to the base and located below the base.

[0012] The connecting rod has a cavity adapted to the adjusting rod, and the adjusting rod has a screw hole adapted to the locking bolt.

[0013] The crossbar has an insertion slot that is adapted to the insertion block.

[0014] This utility model discloses an integrated support device for an LED projection screen. In practical use, the base is placed on the working surface, the connecting rod is inserted into the mounting frame, and the mounting bolts lock the connecting rod to the mounting frame.
