Abstract
Description
Technical Field
[0001] The utility model relates to an extra-wide rolling curtain. Background Art
[0002] Rolling curtains mainly include electric rolling curtains, beaded rolling curtains, and spring rolling curtains. Rolling curtains have many advantages such as beautiful and concise appearance, and firm and durable structure. They are suitable for a variety of places, such as commercial office buildings, hotels, restaurants, offices, and homes (used as screen curtains), especially suitable for large-area glass curtain walls. When the curtain fabric is lowered, it can make the indoor light soft and avoid the trouble of direct sunlight, achieving a good sunshade effect. When the rolling curtain is raised, its volume is very small and it is not easily noticed.
[0003] However, due to the lack of good support in the middle section of the extra-wide rolling curtain, the problem that the winding tube bends under the action of gravity often occurs. After the winding tube bends, the curtain fabric will wrinkle, affecting the aesthetics. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an extra-wide rolling curtain to solve the technical problems mentioned in the above background art.
[0005] The technical solution for achieving the purpose of the utility model is: an extra-wide rolling curtain, including a winding tube and a housing. The winding tube is arranged in the housing. A curtain cloth is wound around the winding tube. The housing includes a bottom plate. A support surface is arranged on the bottom plate. A non-vertical sliding groove is arranged at the end of the housing. When the curtain cloth is unfolded or wound up, the winding tube moves along the length direction of the sliding groove, and the curtain cloth on the winding tube always abuts against the support surface, and the support surface provides a supporting force for the winding tube.
[0006] Further, the housing further includes a top plate, a first side plate, and a second side plate. The top plate is connected to the first side plate and the second side plate. The first side plate is connected to the bottom plate. There is a gap between the second side plate and the bottom plate. The curtain cloth passes through the gap. The support surface is arranged on the side of the bottom plate close to the gap, and the side of the support surface close to the second side plate is higher than the side far from the second side plate.
[0007] Further, a bottom plate patch is arranged on the upper surface of the bottom plate, and the bottom plate patch is made of a wear-resistant and smooth-surface material.
[0008] Further, end caps are arranged at both ends of the housing. Sliding grooves are arranged on the end caps. A sliding component is connected to the end of the winding tube, and the sliding component slides in the sliding grooves.
[0009] Further, the sliding grooves are arranged horizontally.
[0010] Further, the sliding grooves are arranged obliquely, and the end close to the support surface is lower than the end far from the support surface.
[0011] Further, the sliding component includes a fixing plate and a pulley. The pulley is arranged on the fixing plate and is matched with the sliding groove.
[0012] A tail plug is rotatably arranged on one of the fixing plates, and a motor is fixed on the other fixing plate. One end of the winding tube is sleeved on the tail plug, and the other end is sleeved on the motor and is in transmission connection with the output shaft of the motor.
[0013] By adopting the above technical solutions, the utility model has the following beneficial effects:
[0014] (1) In the utility model, a supporting surface is arranged on the bottom plate. As the winding tube moves along the length direction of the sliding groove when the curtain cloth is wound or unfolded, the curtain cloth on the winding tube always abuts against the supporting surface by the gravity of the already unfolded curtain cloth and the lower beam, and the rolling curtain is supported by the supporting surface to prevent the winding tube from bending.
[0015] (2) A bottom plate patch is arranged on the upper surface of the bottom plate of the utility model. The bottom plate patch is made of wear-resistant and smooth-surface materials, which can reduce the wear of the curtain cloth.
[0016] (3) After the curtain cloth of the utility model is wound up, the weight of the unfolded curtain cloth plus the lower beam may not be able to pull the winding tube. Therefore, the sliding groove is set obliquely, and the winding tube moves towards the supporting surface by the gravity of the winding tube and the winding part of the curtain cloth.
[0017] (4) In the utility model, through the cooperation of the roller and the sliding groove, the winding tube can move along the length direction of the sliding groove when the curtain cloth is wound or unfolded, so as to achieve the effect that the curtain cloth always abuts against the supporting surface.
[0018] (5) One end of the winding tube of the utility model is sleeved on the tail plug, and the other end is sleeved on the output shaft of the driving motor. The automatic winding and unwinding of the curtain cloth is realized through the operation of the motor. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] (Embodiment 1)
[0032] See Figure 1-2 , the extra-wide roller shutter of this embodiment includes a roller tube 1 and a casing 2. The roller tube 1 is arranged in the casing 2, and a curtain cloth 3 is wound around the roller tube 1. The casing 2 includes a bottom plate 2-1, and a support surface 2-1-1 is arranged on the bottom plate 2-1. A non-vertical sliding groove 4 is arranged at the end of the casing 2; when the curtain cloth 3 is unfolded or wound up, the roller tube 1 moves along the length direction of the sliding groove 4, and the curtain cloth 3 on the roller tube 1 is always in contact with the support surface 2-1-1, and the support surface 2-1-1 provides a supporting force for the roller tube 1. In this embodiment, by arranging the support surface 2-1-1 on the bottom plate 2-1, the roller tube 1 moves along the length direction of the sliding groove 4 as the curtain cloth 3 is wound up or unfolded, and the curtain cloth 3 on the roller tube 1 always contacts the support surface 2-1-1 by relying on the gravity of the already unfolded curtain cloth 3 and the lower beam, and the roller shutter is supported by the support surface 2-1-1 to prevent the roller tube 1 from bending.
[0033] The casing 2 further includes a top plate 2-2, a first side plate 2-3 and a second side plate 2-4. The top plate 2-2 is connected to the first side plate 2-3 and the second side plate 2-4. The first side plate 2-3 is connected to the bottom plate 2-1. There is a gap 5 between the second side plate 2-4 and the bottom plate 2-1, and the curtain cloth 3 passes through the gap 5; the support surface 2-1-1 is arranged on the side of the bottom plate 2-1 close to the gap 5, and the side of the support surface 2-1-1 close to the second side plate 2-4 is higher than the side away from the second side plate 2-4.
[0034] A bottom plate patch is arranged on the upper surface of the bottom plate 2-1. The bottom plate patch is made of a wear-resistant and smooth surface material, which can reduce the wear of the curtain cloth 3.
[0035] End caps are arranged at both ends of the casing 2, and sliding grooves 4 are arranged on the end caps. A sliding component is connected to the end of the roller tube, and the sliding component slides in the sliding groove 4. The sliding component includes a fixing plate and a pulley. The pulley is arranged on the fixing plate, and the pulley cooperates with the sliding groove 4. In this embodiment, the sliding groove 4 is horizontally arranged.
[0036] A tail plug is rotatably arranged on one fixing plate, and a motor is fixed on the other fixing plate. One end of the winding tube is sleeved on the tail plug, and the other end is sleeved on the motor and is in transmission connection with the output shaft of the motor. Therefore, when the motor rotates, it can drive the winding tube to rotate, and the automatic retraction and extension of the curtain cloth are realized through the operation of the motor. Driving the winding tube to rotate by the motor is a mature technology in the industry, which can be achieved by means of splines or by clamping with a cross square groove, etc., and will not be elaborated here.
[0037] The working principle of the present utility model is as follows: The curtain cloth 3 of the unfolded part and the lower beam connected to the lower end of the curtain cloth 3 both have their own weights, which can provide a pulling force for the winding tube 1 towards the supporting surface 2-1-1, so that the curtain cloth 3 is always in contact with the supporting surface 2-1-1, and the supporting surface 2-1-1 provides a supporting force for the winding tube 1. When the curtain cloth 3 is retracted, the radius of the winding tube 1 increases, and the winding tube 1 moves along the sliding groove 4 in a direction away from the supporting surface 2-1-1; when the curtain cloth 3 is unfolded, the radius of the winding tube 1 decreases, and the winding tube 1 moves along the sliding groove 4 in a direction close to the supporting surface 2-1-1.
[0038] (Embodiment 2)
[0039] See Figure 3-4 In this embodiment, the sliding groove 4 is inclined, and the end close to the supporting surface 2-1-1 is lower than the end far from the supporting surface 2-1-1. When the curtain cloth 3 is retracted, the weights of the unfolded curtain cloth 3 and the lower beam are relatively small. If the curtain cloth 3 and the lower beam are light, they may not be able to pull the winding tube 1 to move towards the supporting surface 2-1-1. Therefore, the sliding groove 4 is set obliquely, and the weights of the winding tube 1 and the retracted part of the curtain cloth 3 will also make the winding tube 1 move towards the supporting surface 2-1-1. In this way, the curtain cloth 3 and the lower beam can be made lighter, reducing the burden on the winding tube 1 and at the same time reducing the power of the motor.
[0040] The specific embodiments described above have further elaborated the purpose, technical solution and beneficial effects of the present utility model. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
