Description

Technical Field

[0001] The utility model relates to the technical field of screens, in particular to a reel-type movable and portable projection screen. Background Art

[0002] The screen specially used for projection is called projection screen. It is one of the most commonly used products among projector peripheral equipment. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. From the function point of view, the projection screen can generally be divided into two types: reflective and transmissive. The reflective type is used for front projection, and the transmissive type is used for rear projection. The front projection screen is divided into flat screen and curved screen. From the texture point of view, it can be divided into glass screen, metal screen, embossed plastic screen, etc. Since the screen is used in many scenarios, it is necessary to optimize the structure of the screen.

[0003] For example, a projection screen is disclosed in a Chinese utility model patent with a publication number of CN218213772U. Although the above-mentioned prior art can complete the positioning of the screen body through the rotating shaft and the fixing rod, and can realize the fixed support of the screen body through the first support rod and the second support rod, and is easy to install, when the screen is used for outdoor activities, it is generally fixed directly on the rack, and the rack can only be climbed up to take down the screen after the activity. Due to the uncontrollable outdoor weather, strong winds or rain during the activity will increase the difficulty of taking down the screen. As long as the screen is not taken down from the rack in time, it will cause damage to the screen. Therefore, it is necessary to design a screen that can be moved when in use. Utility Model Content

[0004] In order to solve the technical problem that a screen used outdoors cannot be directly moved, the utility model provides a reel-type movable portable projection screen.

[0005] The utility model is implemented by the following technical scheme: a reel-type movable portable projection screen comprises a screen, both sides of the screen are provided with a reeling assembly for reeling the screen, one side of each reeling assembly is provided with a moving assembly for enabling the screen to move when unfolded for use, a plurality of stabilizing assemblies for stably supporting the screen when in use are provided between the two reeling assemblies, the moving assembly comprises a fixed block which is arranged at one side of the reeling assembly and has a first socket, a connecting rod with one end plugged into the first socket, and a base which is arranged at one end of the connecting rod.

[0006] Through the above technical solution, when the screen is used outdoors, if the screen needs to be moved, it only needs to push the moving component.

[0007] As a further improvement of the above solution, a plurality of rotation grooves are provided at the bottom of the base, and a roller is rotatably installed inside each of the rotation grooves.

[0008] Through the above technical solution, the rollers cooperate with the base to allow the screen to be moved without being disassembled.

[0009] As a further improvement of the above scheme, the winding assembly includes a winding box arranged on one side of the curtain and a winding column rotatably installed inside the winding box, one side of the curtain passes through the winding box and is wound and connected with the internal winding column, one end of the winding column passes through the winding box and extends to its outside, and the two fixed blocks are fixedly installed on the adjacent winding boxes.

[0010] Through the above technical solution, the curtain can be rolled up by rotating the rolling post.

[0011] As a further improvement of the above scheme, the stabilizing assembly includes a first stabilizing rod arranged on one side of the curtain and a second stabilizing rod arranged at one end of the first stabilizing rod, and one end of the first stabilizing rod and the second stabilizing rod are both rotatably mounted with a first rotating block, and the two first rotating blocks are rotatably mounted with adjacent winding boxes.

[0012] Through the above technical solution, the first stabilizing bar cooperates with the second stabilizing bar to provide support for the screen when it is used outdoors, thereby reducing the shaking of the screen caused by wind.

[0013] As a further improvement of the above scheme, a fixing groove is opened on one side of the second stabilizing rod, a second rotating block is rotatably installed on one side of the first stabilizing rod, and a limiting plate arranged in an "L" shape is fixedly installed on one side of the second rotating block, and the limiting plate is adapted to the fixing groove.

[0014] Through the above technical solution, the limiting plate can fix the first stabilizing bar and the second stabilizing bar to prevent the two stabilizing bars from separating.

[0015] As a further improvement of the above solution, a rotating shaft is rotatably mounted on one side of the first stabilizing bar and the second stabilizing bar, and a clamping plate for clamping the curtain is fixedly mounted on one side of the two rotating shafts.

[0016] Through the above technical solution, the clamping plate will press the curtain onto the first stabilizing rod and the second stabilizing rod to prevent the curtain from shaking.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a rolling assembly, a moving assembly and a stabilizing assembly. The rolling assembly can roll up the curtain in a reel-like manner. The moving assembly can move the position of the curtain during use, which is convenient for coping with outdoor weather. The moving assembly adopts a spliced ​​structure. When the curtain is not in use, the moving assembly can be disassembled for easy carrying. The stabilizing assembly can stabilize the curtain outdoors to prevent the curtain from being shaken by the wind. This arrangement allows the curtain to be moved when in use, which is convenient for coping with emergencies, and most of the components can be disassembled when the curtain is not in use, which is convenient for carrying and transportation.
