DETAILED DESCRIPTION

[0024] Example 1

[0025] like Figure 1 , Figure 2 As shown, this embodiment includes a cross bar 1, a mounting member 2 and a pneumatic blade 3.

[0026] like Figure 3 , Figure 4 As shown, in this embodiment, the crossbar 1 is in the shape of a round bar, and in other embodiments, the crossbar 1 may also be in the shape of a square bar or other strip-shaped structures. In this embodiment, the lower part of the crossbar 1 is provided with a long strip-shaped opening slot 1a that runs through both ends of the crossbar 1 along the length direction of the crossbar 1, and the opening slot 1a is a semicircular structure in cross section, and a rounded corner is also provided at the opening end 1c of the opening slot 1a. In other embodiments, the opening slot 1a may also only run through one end of the crossbar 1, or the opening slot 1a may only be in the shape of a shorter strip; in another embodiment, the opening slot 1a is in other structures such as a rectangular cross section.

[0027] In this embodiment, U-shaped bayonet 1b lying sideways is provided at both ends of crossbar 1, and threaded holes are provided at the ends of bayonet 1b along the length direction of crossbar 1. Specifically, the threaded holes are provided at the upper part of crossbar 1. Since only the open groove 1a penetrating the two ends of crossbar 1 is provided at the lower part of crossbar 1 in this embodiment, sufficient entities are left at the upper part of crossbar 1 to provide threaded holes at the ends along the length direction. In this embodiment, U-shaped bayonet 1b lying sideways is provided to fix crossbar 1 to cable 6. In other embodiments, if crossbar 1 is fixed to strip, bayonet 1b may not be provided, and threaded holes may be provided directly at the ends of crossbar 1 along the length direction, and crossbar 1 may be fixed to strip with bolts.

[0028] like Figure 5 As shown, in this embodiment, the shape of the mounting member 2 corresponds to the shape of the opening slot 1a, and the mounting member 2 is clamped in the opening slot 1a. The mounting member 2 can slide back and forth in the opening slot 1a along the length direction of the cross bar 1 but cannot be separated from the opening slot 1a. The opposite ends of the two mounting members 2 are provided with clamping slots 2a, the depth direction of the clamping slots 2a is the same as the length direction of the cross bar 1, and its cross section is fan-shaped.

[0029] Furthermore, in this embodiment, a groove a is provided on the side of the bottom of the slot 2a. The shape and position of the groove a correspond to the rounded corner provided at the opening end 1c of the opening slot 1a. The connection between the rounded corner and the groove a can prevent the mounting member 2 from shaking in the opening slot 1a when the pneumatic blade 3 swings. In this embodiment, grooves a are provided on both sides of the bottom of the slot 2a. In other embodiments, only one groove a may be provided.

[0030] Under this structure, since a groove a corresponding to the rounded corner of the opening end 1c can be set at the bottom of the mounting member 2, the bottom of the mounting member 2 will inevitably extend beyond the opening end 1c, and the extending portion can be used as a sliding portion 2b. The sliding portion 2b can be used to push the mounting member 2 from the outside to slide in the length direction of the cross bar 1, which is convenient for installation and adjustment.

[0031] In this embodiment, the pneumatic blade 3 is in the shape of a square blade, and a hanging ear 3a is provided at each end of the top edge of the pneumatic blade 3. The two hanging ears 3a are placed in two slots 2a respectively. Under the restriction of the slots 2a, the pneumatic blade 3 can only swing back and forth between the two open ends 1c. In other embodiments, the pneumatic blade 3 can also be in a trapezoidal shape or other shapes, and the hanging ears 3a can also be provided on one side or in the middle of the top edge according to the specific situation.

[0032] This embodiment also provides a plug 4, such as Figure 6 As shown, one end of the plug 4 is used as a cover plate 4a to cover the end face of the cross bar 1. The shape of the cover plate 4a corresponds to the end face of the cross bar 1. The other end of the plug 4 corresponds to the shape of the opening slot 1a and is blocked at the end of the opening slot 1a. Furthermore, a groove a with a rounded corner that is provided to hold the opening end 1c is also provided at the bottom of the other end of the plug 4. The part of the bottom of the other end of the plug 4 that exceeds the opening end 1c can be used as a disassembly part 4b for pulling out the plug 4. Of course, when plugging, some specific structures should be provided on the other part of the plug 4 to avoid interference with the top screw 5. For example, in this embodiment, an arc-shaped notch 4c is provided to provide installation space for the top screw 5.

[0033] Example 2

[0034] like Figure 7 As shown, this embodiment provides a pneumatic curtain wall based on the pneumatic assembly of embodiment 1, specifically comprising a plurality of vertically arranged cables 6, the bayonet 1b at both ends of the crossbar 1 is clamped on the cables 6, and then the pneumatic assembly is fixed on the cables 6 by the top screw 5. A plurality of pneumatic assemblies are arranged in the shape of a wall on the cables 6 to form a curtain wall structure. In other embodiments, the cables 6 can be replaced by pull rods.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
