The protection nets 200 on both sides and the other protection net 200 may use the protection net 200 of the same parameter, which facilitates installation, procurement, and the like. The protection nets 200 with different parameters may be used, and since the protection net 200 corresponding to the elastic cushion 100 is the main force-bearing protection net 200, the strength of the protection net 200 is greater than the protection nets 200 on both sides.
The protective nets 200 on the two sides are fixedly connected with the other protective net 200 in a welding mode, so that the stability is higher.
The rotating door 400 is installed on one of the protection nets 200 at both sides and is hinged by a hinge or a hinge, so that the rotating door 400 can be conveniently operated by a worker to rotate.
The hinge allows the swing door 400 to be converted between opening and closing, and the conventional hinge does not have a spring hinge function, and preferably has a collision bead to prevent wind from blowing after all the hinges are installed. With the continuous improvement of hinges, the styles of adapting to different functions also appear, and besides common hinges, the hinges also comprise a hinged door hinge, a hinged window hinge, a light hinge and the like.
The hinge is usually a four-bar or six-bar structure, and has other similar structural modes, and the main bearing force is external forces such as vertical gravity and wind force. With the presence of the hydraulic hinge, the hinge has a cushioning effect when the swing door 400 is closed, reducing noise occurring at the time of collision.
Hinges are also commonly referred to as hinges, since they function in the same way as hinges, and can generally be replaced by others. However, when the hinge is used, the hinge only rotates, and the hinge can still translate when being installed to rotate. From the mounted position, the hinge mainly is used for door and window, and the hinge is more uses in furniture such as cupboard, and some special circumstances must use the hinge, like super large flat-open window, has great requirement to the atress, preferably uses the hinge, if adopt the hinge, then need a plurality of hinges atress jointly, just can have to lack on aesthetic measure.
When the hinge is installed on the swing door 400, since it does not provide friction by itself, it is required to be used on the window together with the hinge, and since it does not provide friction like a hinge by itself, it is often required to provide a scratch capable of preventing damage from blowing back the window when wind is too strong. The friction of the hinge can enable the hinge to be used independently without matching with other parts. However, the length of the outer wall is different when the window is used on the rotating window and the flat-open window.
Can set up simultaneously and set up mounting groove 510 and gag lever post on installation pole 500, namely, be equipped with the mounting groove 510 that sets up along installation pole 500 length direction on the relative one side of installation pole 500, the both sides of elastic backing plate 100 are installed respectively in two mounting grooves 510, and the lower extreme of installation pole 500 is equipped with the limiting plate 540 that is used for supporting elastic backing plate 100.
Set up mounting groove 510 along installation pole 500 length direction and on two installation poles 500 sides that are close to mutually, when with elastic backing plate 100 fixed connection on two installation poles 500, elastic backing plate 100 enters into mounting groove 510 in, it is spacing to elastic backing plate 100 by the groove lateral wall of mounting groove 510, and the gag lever post also carries on spacingly to elastic backing plate 100 simultaneously.
Since the elastic pad 100 has a certain elasticity, the cross-sectional size of the elastic pad 100 is set to be slightly larger than the contour size of the installation groove 510, and is caught in the installation groove 510 by the restoring force of the elastic pad 100. After the elastic pad 100 is mounted on the two mounting rods 500, the limiting plate 540 at the lower end of the elastic pad 100 contacts and is supported by the limiting plate 540 for limiting, thereby further improving the stability of mounting the elastic pad 100. The limiting plate 540 may be installed in the installation groove 510, and the limiting plate 540 may be installed outside the installation groove 510, and may be inclined upward, and after the elastic packing plate 100 is installed in the installation groove 510, the limiting plate 540 may effectively prevent the elastic packing plate 100 from being separated from the installation groove 510.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
