The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model embodiment provides an indoor transparent bowl curtain with anti-collision function, such as Figure 1-4 As shown, it includes a PVC inflatable transparent bowl curtain 1, and a first track 2 and a second track 3 are arranged at the outer position of the PVC inflatable transparent bowl curtain 1. The first track 2 is located on one side of the second track 3, and the first track 2 and the second track 3 are horizontal, and the bottoms of the first track 2 and the second track 3 are lower than the bottom of the PVC inflatable transparent bowl curtain 1. A servo motor 4 is fixedly connected to the central position of the outer wall of one side of the first track 2 by bolts, and the servo motor 4 is fixedly connected to a first ball screw 5 through an output end of one side thereof, and a second ball screw 6 is fixedly connected to the end of the first ball screw 5 away from the output end of the servo motor 4 through a key connection, and the screw threads in the first ball screw 5 and the second ball screw 6 are opposite in rotation direction, and the nut seat on the first ball screw 5 is fixed by a screw The first movable plate 7 is fixedly connected with the first ball screw 6, the nut seat on the second ball screw 6 is fixedly connected with the second movable plate 8 by screws, the tops of the first movable plate 7 and the second movable plate 8 are fixed with anti-collision airbag covers 9 by adhesive, the bottoms of the two anti-collision airbag covers 9 are fixed to the tops of the first movable plate 7 and the second movable plate 8 in a two-point manner, a reflective sticker 10 is fixed to the outer wall of one side of the anti-collision airbag cover 9 by adhesive, the outer walls of one side of the first movable plate 7 and the second movable plate 8 are fixedly connected with an air pump 11 by bolts, and an air pump switch 12 is embedded in a position on one side of the outer wall of one side of the first movable plate 7 and the second movable plate 8 near the air pump 11, and a connecting air pipe 13 is fixedly connected between the air pump 11 and the anti-collision airbag cover 9.
[0022] It should be noted that, since most of the existing transparent bowl curtains have high transparency, flying birds, bats and other flying objects in the air can easily collide with the transparent bowl curtain during flight, which not only easily causes the transparent bowl curtain to be punctured, but the bodies of birds, bats and other flying objects after the collision will remain on the transparent bowl curtain, affecting the display quality. There is a lack of effective anti-collision structure. In this embodiment, two inflated anti-collision airbag covers 9 move towards each other and then surround the outside of the PVC inflatable transparent bowl curtain 1. The anti-collision airbag covers 9 are used to withstand the impact of birds, bats and other flying objects, thereby preventing the PVC inflatable transparent bowl curtain 1 from being damaged by impact or residual dirt. The flat state of the anti-collision airbag cover 9 after deflation can reduce the occupied space and volume.
[0023] Specifically, in the present embodiment, the present scheme mainly includes an anti-collision airbag cover 9. When the PVC inflatable transparent bowl curtain 1 is not performing projection work, the PVC inflatable transparent bowl curtain 1 is in a transparent state. At this time, the air pump switch 12 is turned on. After the air pump 11 is powered on, external air is drawn into the anti-collision airbag cover 9. The air pressure in the anti-collision airbag cover 9 increases and expands. The inflated anti-collision airbag cover 9 presents a quarter hollow hemispherical structure. The servo motor 4 is controlled to drive the first ball screw 5 and the second ball screw 6 to rotate through the output end on one side thereof. Since the screw threads in the first ball screw 5 and the second ball screw 6 rotate in opposite directions, the first movable plate 7 on the first ball screw 5 and the second ball screw 6 on the second movable plate 7 on the second ball screw 6 on the first ball screw 5 rotate. The second movable plate 8 moves toward each other, and the anti-collision airbag covers 9 on the first movable plate 7 and the second movable plate 8 move toward each other synchronously. The two anti-collision airbag covers 9 are combined to surround the outside of the PVC inflatable transparent bowl curtain 1. The anti-collision airbag covers 9 are used to protect the PVC inflatable transparent bowl curtain 1, and the reflective stickers 10 are used for reflection. Birds, bats and other flying objects in the air will first hit the anti-collision airbag covers 9. The anti-collision airbag covers 9 provide anti-collision protection for the PVC inflatable transparent bowl curtain 1. When the PVC inflatable transparent bowl curtain 1 needs to be used, the anti-collision airbag covers 9 are controlled to reset, and the air in the anti-collision airbag covers 9 is released. The anti-collision airbag covers 9 are stored in a flat state on the first movable plate 7 and the second movable plate 8.
[0024] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the first rail 2 and the second rail 3 are both slidably connected to the first movable plate 7 , and the first rail 2 and the second rail 3 are both slidably connected to the second movable plate 8 .
[0025] In this embodiment, the stability of the movement of the first moving plate 7 and the second moving plate 8 on the first rail 2 and the second rail 3 is ensured by the sliding connection.
[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, the inner radius of the anti-collision airbag cover 9 is larger than the inner radius of the PVC inflatable transparent bowl curtain 1. After being inflated, the anti-collision airbag cover 9 has a quarter hollow hemispherical structure, and the anti-collision airbag cover 9 is made of red PVC material.
[0027] In this embodiment, the anti-collision airbag cover 9 with a quarter hollow hemispherical structure can be used to surround the two anti-collision airbag covers 9 on the outside of the PVC inflatable transparent bowl curtain 1. The anti-collision airbag cover 9 provides anti-collision protection for the PVC inflatable transparent bowl curtain 1. The red anti-collision airbag cover 9 can enhance the warning effect and prevent flying objects such as birds and bats flying in the air from colliding with the anti-collision airbag cover 9.
