Preferably, in the original winding and unwinding structure of the projection curtain, a vertical rod is formed on one side of the horizontal support plate, a locking arm is rotatably connected to the position, close to the top, of the vertical rod, a hook body is formed at one end, deviating from the vertical rod, of the locking arm, and the hook body hooks the middle of the support rod and protrudes to form a convex rod.
Preferably, in the original winding and unwinding structure of the projection curtain, the support rod is inclined to one side away from the vertical rod.
Preferably, in the original winding and unwinding structure of the projection curtain, a supporting diagonal rod is formed between the vertical rod and the horizontal supporting plate.
Preferably, in the original winding and unwinding structure of the projection curtain, the support rod is rotatably provided with two rollers below the notch, and the two rollers support the curtain roller.
Compared with the prior art, the technical scheme improves the winding and unwinding convenience.
Drawings
In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present application, and other drawings can be obtained by those skilled in the art without creative efforts.
Fig. 1 is a schematic view of an original winding and unwinding structure of a projection curtain according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described in detail below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1, an original winding and unwinding structure 100 of a projection curtain comprises a horizontal support plate 101, wherein two ends of the horizontal support plate 101 are respectively and symmetrically provided with a roller lifting structure, the roller lifting structure comprises a support rod 102 and a cylinder 103, the bottom of the cylinder is rotatably mounted on the horizontal support plate 101, the cylinder 102 is driven to rotate, a fixed end of the cylinder 103 is fixedly mounted on the horizontal support plate 101, an output end of the cylinder 103 is fixedly mounted on the support rod 102 near the top, and a notch 105 for supporting a curtain roller 104 is formed at the top of the support rod 102.
In this embodiment, because the curtain cloth roller is all heavier after the rolling with unreel before, hardly lifts up, this structure has realized the convenience of rolling and unreeling through the cooperation that sets up hydro-cylinder and bracing piece. During specific operation, when the screen roller is unreeled, the oil cylinder is firstly lowered, the supporting rod is dropped, the screen roller is rolled into the notch, and then the screen roller is lifted up through the driving of the oil cylinder; when the rolling is finished, the operation is opposite.
Furthermore, a vertical rod 106 is formed on one side of the horizontal support plate 101, a locking arm 107 is rotatably connected to the position, close to the top, of the vertical rod 106, a hook 108 is formed at one end, away from the vertical rod 106, of the locking arm 107, and a protruding rod 109 is formed by the hook 108 hooking the middle of the support rod 102 in a protruding manner.
In the embodiment, the locking arm ensures the possible force releasing situation of the oil cylinder, thereby preventing danger.
Further, the support rod 102 is inclined to a side away from the vertical rod 106.
In this embodiment, a triangular stabilizing structure is formed.
Further, a support diagonal bar 110 is formed between the vertical bar 106 and the horizontal support plate 101.
In this embodiment, a triangular stabilizing structure is also formed.
Further, the support bar 102 is rotatably mounted with two rollers 111 below the slot 105, and the two rollers 111 support the curtain roller 104.
In this embodiment, reduce the resistance of curtain roller rolling and unreeling.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
