Detailed Description

The present invention will be described in more detail with reference to the following examples, which are illustrated in the accompanying drawings. This example is merely a description of the best mode of carrying out the invention and is not intended to limit the scope of the invention in any way.

As shown in fig. 1 to 2, a pneumatic window opener comprises a bidirectional cylinder 2 connected to a wing window 1, wherein two quick-connect plugs 12 are arranged on one side of the bidirectional cylinder 2, an air spring 4 which always provides unidirectional external thrust for the wing window 1 is arranged on the side far away from the quick-connect plugs 12, one side edge of the wing window 1 is hinged to a frame 3 through a hinge 11, the rear end of the bidirectional cylinder 2 is fixed on the frame 3 through a support 5, and the front end of a telescopic rod of the bidirectional cylinder 2 is connected with the wing window 1 through a first connecting piece 6; the air spring 4 is fixedly connected with the bidirectional cylinder 2 through a fixing piece 7, and the front end of a telescopic rod of the air spring 4 is fixedly connected with a telescopic rod of the bidirectional cylinder 2 through a second connecting piece 8; under the condition of the bidirectional cylinder 2 or failure, the outward pushing force of the gas spring 4 can open the wing window 1.

One side of the gas spring 4, which is far away from the bidirectional cylinder 2, is hinged with a locking sleeve 15, a fixing rod 16 is arranged in the locking sleeve 15, fixing holes are arranged on the surfaces of the locking sleeve 15 and the fixing rod 16 in a penetrating manner, a bolt matched with the fixing holes is arranged, one end of the fixing rod 16 is fixedly connected with a fixing ring 17, and the fixing ring 17 is sleeved on the periphery of a telescopic rod of the gas spring 4 and abuts against the second connecting piece 8.
