[0021] Embodiment 1

[0022] As Figures 1-3 shown, this embodiment includes a cross bar 1, a mounting member 2, a pneumatic piece 3, and a pin shaft 4.

[0023] The cross bar 1 in this embodiment is a rod with an oval cross section. An opening slot 1a is provided at the lower part of the cross bar 1. The opening slot 1a is in a long strip shape and runs through both ends of the cross bar 1 along the length direction of the cross bar 1. In this embodiment, the opening slot 1a is a long strip with a wider upper part and a narrower lower part. Specifically, the cross section of the opening slot 1a is similar to a fan shape.

[0024] The shape of the mounting member 2 corresponds to the shape of the opening slot 1a. That is, the mounting member 2 is in the shape of a strip with a wider top and a narrower bottom in cross-section. Specifically, the cross-section of the mounting member 2 is also similar to a sector. The two mounting members 2 are inserted into the opening slot 1a from both ends. The mounting member 2 can move back and forth along the length direction in the opening slot 1a, but cannot fall out from the opening of the opening slot 1a. Further, in this embodiment, a clamping groove 2c is provided at the bottom of the mounting member 2, and the clamping groove 2c is clamped on the opening of the opening slot 1a. The clamping groove 2c can play a role in positioning the mounting member 2 to prevent the mounting member 2 from swinging together when the pneumatic piece 3 swings.

[0025] In this embodiment, first slot holes 2a are provided at the opposite ends of the two mounting members 2, and the first slot holes 2a are used to place the pin shaft 4. Further, second slot holes 2b are provided at the opposite ends of the two mounting members 2, and the second slot holes 2b of the mounting member 2 are not communicated. The second slot holes 2b are symmetrical to the first slot holes 2a. In this way, when installing the mounting member 2, there is no need to consider the direction. At the same time, in some cases, when plugs are needed to block both ends of the opening slot 1a, the second slot holes 2b can be used as the mounting holes for the plugs.

[0026] One end of the pneumatic piece 3 is provided with a sleeve 3a. Specifically, the pneumatic piece 3 in this embodiment is in the shape of a square sheet, and one side of the pneumatic piece 3 is rolled into the shape of a sleeve 3a.

[0027] The pin shaft 4 penetrates through the sleeve 3a, and both ends of the pin shaft 4 are respectively arranged in the two first slot holes 2a. The pneumatic piece 3 can rotate around the axis of the pin shaft 4.

[0028] Under the above structure, the rotating parts of the pneumatic piece 3, including the pin shaft 4 and the sleeve 3a, are all hidden in the opening slot 1a of the cross bar 1. And the sleeve 3a and the pin shaft 4 are used as the rotating structure of the pneumatic piece 3, which has good strength and is durable.

[0029] Embodiment 2

[0030] This embodiment is basically the same as Embodiment 1. The difference is that in this embodiment, only one mounting member 2 is provided. In addition, the opening slot 1a only penetrates one end of the cross bar 1 along the length direction of the cross bar 1, and a third slot hole opposite to the first slot hole 2a is provided at the non-penetrated end face of the opening slot 1a. Both ends of the pin shaft 4 are respectively arranged in the first slot hole 2a and the third slot hole.

[0031] Under the structure of this embodiment, the function of hiding the rotating part of the pneumatic piece 3 can also be achieved.

[0032] The second difference is that the pneumatic piece 3 in this embodiment includes an installation part and a blade part. The installation part is in the shape of a sleeve, and the blade part is in the shape of a polygonal sheet. One side of the blade part is parallel to the axis line of the installation part and is welded to the side wall of the installation part. In other embodiments, the blade part and the installation part can also adopt an integrally formed structure. The installation part in this embodiment uses a sleeve 3a. In another embodiment, the sleeve 3a can adopt several short sleeves arranged coaxially and at intervals, or a structure in which one or several gaps are arranged at intervals on a sleeve 3a.

[0033] The third difference is that the second slot 2b of the installation piece 2 communicates with the first slot 2a and can be drilled through in one go, which can reduce the processing cost.

[0034] Embodiment 3

[0035] This embodiment is a pneumatic curtain wall based on Embodiment 1, including several steel wires 5, set screws, and the coiling pin shaft curtain wall structure in Embodiment 1.

[0036] To facilitate the installation of the cross bar 1 and the steel wire 5, this embodiment is provided with a notch 1b at the end of the cross bar 1, and the steel wire 5 is clamped into the notch 1b. The part of the notch 1b located above the opening groove 1a is provided with threads, and the cross bar 1 can be fixed on the steel wire 5 by engaging the set screw with the threads. In addition to fixing the cross bar 1, the steel wire 5 can also play a role in preventing the installation piece 2 from disengaging from the opening groove 1a.

[0037] In this embodiment, several steel wires 5 are arranged in a vertical array, and the two notches 1b at both ends of several cross bars 1 are clamped on adjacent steel wires 5 to form a curtain wall structure.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
