Description

Technical Field

[0001] The invention relates to the technical field of projection screen equipment, in particular to an electric opening and closing door type projection screen. Background Art

[0002] Projection screen is one of the most commonly used products in projector peripheral equipment. Projection screen is the abbreviation of projection screen. If the projection screen is properly matched with the projector, high-quality projection effects can be obtained. The projector shines light onto the projection screen, and the projected pictures or videos can be seen. At present, all electric projection screens with door panels on the market are basically divided into three categories. The first category is the lower rod door panel, that is, the lower rod is used as the door panel. The second category is the semi-automatic door panel, which pulls the door panel to close when the rod rises. The third category is the electric door panel. The door panel is pulled by other mechanical structures driven by the motor.

[0003] However, the currently used electric opening and closing door projection screen has the following shortcomings:

[0004] 1. The currently used electric opening and closing door projection screen has fewer force points on the door panel, which makes the force on the door panel uneven when opening and closing the door panel, making it sometimes impossible to open and close the door panel normally, resulting in length limitations.

[0005] 2. The currently used electric opening and closing door projection screen cannot be stressed at the same time when the door panel is opened, which makes the door panel easily damaged, making it impossible to put down the projection screen, making maintenance troublesome and increasing the cost of use. Summary of the invention

[0006] The object of the present invention is to provide a projection screen with an electric opening and closing door to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an electric opening and closing door-type projection screen, comprising a shell, a door panel is movably provided at the bottom end of the shell through a hinge, a silicone strip is fixedly provided on one side of the upper surface of the door panel at the bottom end of the shell, a first tubular motor is fixedly provided inside the shell, a projection screen rotating tube is fixedly provided at one end of the first tubular motor, the output shaft end of the first tubular motor is transmission-connected with the projection screen rotating tube, a projection screen cloth is fixedly provided on the outer side of the projection screen rotating tube, a second tubular motor is fixedly provided on one side inside the shell, a sliding door rotating tube is fixedly provided at one end of the second tubular motor, the output shaft end of the second tubular motor is transmission-connected with the sliding door rotating tube, a sliding door cloth is fixedly provided on the outer side of the sliding door rotating tube, lower rod fixing seats are fixedly provided at both ends of the shell, brackets are fixedly provided at both ends of the shell, and a controller cover is movably provided at one end of the shell close to the first tubular motor.

[0008] Preferably, a hose plug is fixedly provided on one end of the projection screen rotating tube away from the first tubular motor.

[0009] Preferably, a lower rod is fixedly provided at the lower end of the projection screen, lower rod covers are fixedly provided at both ends of the lower rod, and a lower rod sleeve is fixedly provided on a side of the lower rod cover away from the lower rod.

[0010] Preferably, a plurality of springs are fixedly provided at the lower end of the sliding door curtain, a movable spring seat is fixedly provided at the bottom end of the spring, and the bottom end of the movable spring seat is fixedly provided at the top end of the door panel.

[0011] Preferably, a left end cover is fixedly provided on the outer side of one end of the shell, and a right end cover is fixedly provided on the other side of the shell.

[0012] Preferably, both the left end cover and the right end cover are fixedly provided with a decorative cover on a side away from the shell through a decorative cover clamping tube.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention uses a second tubular motor to make the sliding door rotating tube roll up the sliding door curtain and the tension spring to open and close the door panel. The purpose of rolling the sliding door curtain to pull the door panel is to make the entire door panel bear force, which solves the problem of the difference in force on the door panel caused by the different heights of the front and rear ends of the door panel, so that the force on the door panel is uniform and will not be limited by the length;

[0015] 2. The present invention uses a second tubular motor to make the sliding door rotating tube retract the sliding door curtain and the tension spring to open and close the door panel. The purpose of pulling the door panel by rolling the sliding door curtain is to make the entire door panel bear force. The tension spring is used in the middle to prevent the door panel from being damaged due to the uneven height of the front and rear ends of the sliding door curtain. The spring is used as a buffer to make the door panel bear force evenly, which effectively prevents the door panel from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS
