Description

Technical Field

[0001] The utility model relates to the technical field of stage curtain pulling equipment, in particular to an electric-controlled curtain pulling equipment for a stage. Background Art

[0002] Stage electric curtains are often used in traditional stages, luxury concerts, large-scale stage plays, concerts and other occasions to achieve higher stage effects and visual impact. There are two main ways to pull the curtain: horizontal pulling and vertical pulling.

[0003] Announcement No. CN210933807U discloses a stage curtain pulling machine. The utility model has the characteristics of reasonable structure and easy use. By setting a fixed horizontal frame, the pull rope can be smoothly raised, effectively preventing the two sides of the curtain from tilting when the curtain is pulled.

[0004] When the above-mentioned prior art is used, the position of the curtain is adjusted by fixing the curtain on the curtain clamping part and then controlling the up and down movement of the curtain clamping part to realize the lifting and lowering of the curtain. This method requires the horizontal frame to be installed at a very high position, at least twice the reasonable height of the stage performance, so that after the curtain is raised, the curtain will not block the audience's field of vision, which leads to limitations in its scope of application. For some low buildings or outdoor stages (low height), this curtain control method is not suitable, and when installing the electric curtain pulling device, the horizontal frame needs to be fixed first, and then the curtain is installed on the horizontal frame (if the curtain is installed on the horizontal frame first, the overall weight of the curtain and the horizontal frame is very heavy, and it is not convenient to install the horizontal frame). The above-mentioned technology clamps the curtain between the fixed part 21 and the movable part 22, and the overall length of the curtain is very long. It is very difficult to clamp the top of the curtain between the two plates, which requires the cooperation of multiple people, and if there is a difference in the clamping distance, there will be wrinkles.

[0029] Reference Figure 1 - Figure 6 , which is an embodiment of the utility model, provides an electric-controlled curtain-pulling device for stage, which includes: a curtain unit 100 and a control unit 200;

[0030] The curtain unit 100 includes a curtain body 101, a plurality of hanging holes 102 are evenly spaced on the top of the curtain body 101, and a plurality of annular sleeves 103 distributed in an array are fixed on the back of the curtain body 101;

[0031] The control unit 200 includes a rectangular frame 201, and mounting plates 202 are fixed at both ends of the rectangular frame 201. A rotating rod 203 is rotatably connected inside the rectangular frame 201, and multiple take-up drums 204 are fixed at equal intervals outside the rotating rod 203. A pulling rope 205 is slidably connected to the annular sleeves 103 arranged in each column, and one end of the pulling rope 205 is fixed to the take-up drum 204. The number of columns of the multiple annular sleeves 103 is equal to the number of the take-up drums 204, and each column of the annular sleeves 103 and the corresponding take-up drum 204 are on the same vertical plane. When the take-up drum 204 rotates, the pulling rope 205 is reeled or unreeled. A lifting plate 206 is arranged on the back of the curtain body 101, and the other end of the pulling rope 205 is fixed to the lifting plate 206. A suspension component 207 for suspending the top of the curtain body 101 is arranged at the bottom of the rectangular frame 201.

[0032] In addition, the suspension assembly 207 includes a plurality of vertical rods 2071 fixed at equal intervals at the bottom of the rectangular frame 201, a hook 2072 is fixed at the bottom of the vertical rod 2071, the take-up reel 204 and the hook 2072 are arranged alternately, an inner cavity 2073 is provided in the hook 2072, and an arc plate 2074 is slidably connected in the inner cavity 2073, the arc plate 2074 can seal the notch on the hook 2072, and a travel groove 215 is provided on the hook 2072, and The travel groove 215 is connected to the inner cavity 2073, a connecting rod 216 is fixed on the arc plate 2074, and the connecting rod 216 is slidably fitted in the travel groove 215, a shift rod 208 is commonly fixed to the top of the plurality of connecting rods 216, a positioning plate 209 is fixed to the bottom of the rectangular frame 201, a screw 210 is connected to the inner thread of the positioning plate 209, the screw 210 can penetrate the shift rod 208 and be threadedly connected to the shift rod 208, and a handle is fixed to one end of the screw 210.

[0035] When in use, to control the lifting of the curtain body 101, the motor 211 is started to drive the rotating shaft 212 and the active end face gear 213 to rotate. When the active end face gear 213 rotates, it drives the driven end face gear 214 to rotate, and then drives the rotating rod 203 to rotate. When the rotating rod 203 rotates, it drives the take-up drum 204 to rotate, so that the take-up drum 204 reels or unreels the pulling rope 205, thereby driving the curtain body 101 to be lifted and lowered, and the curtain body 101 will not be offset.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
