Abstract
The utility model discloses a quick opening flange fixing structure. One flange of a companion flange is provided with a plurality of open slots along the outer edge, an eye bolt corresponding to the open slots is mounted on another flange. The eye bolt is mounted on two support plates connected with the flanges through a positioning pin. The open slots are formed by the two support plates connected with the flanges. By adopting the eye bolt which can rotate around the positioning pin and be connected with one of the companion flange, the eye bolt penetrates through the open slots to be screwed with a nut so as to function in fastening, thereby fixing two flanges together, when opening the flanges, the nut and a gasket can be separated from the flanges b reversely rotating the nut by a plurality of pitches, and the two flanges can be unlocked and loosened by rotating the eye bolt. Contrarily, the bolt can be fastened by rotating the nut by a plurality of pitches, thereby realizing quick opening of the flanges, and having advantages of convenience, quickness and time and labor saving.
Description
Technical field
The utility model relates to a kind of flange fastening structure, particularly can open fast and fastening flange fastening structure.
Background technique
The normal form that adopts flange to connect on chemical industry equipment and the pressurized container, its fastening means adopts stud and nut fastening more, its dismounting all needs corresponding nut to be screwed off from the double-screw bolt fully or screw on, whole process wastes time and energy, and especially is not suitable for being applied in the occasion that need often carry out dismounting maintain internal structure.
The model utility content
The purpose of this utility model provides a kind of flange fastening structure, only need rotate several pitch during dismounting and not need nut screwed off fully or screw on to get final product, and can realize opening soon convenient power-saving.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of flange fastening structure of opening soon, a slice of companion flange has a plurality of opening slots along outer rim, and corresponding each opening slot of another sheet flange is equipped with swing bolt; Described swing bolt is installed on two support plates that are connected with flange by locating stud; Described opening slot is made of two support plates that are connected with flange.
Structure described in the utility model, adopt swing bolt, can rotate and be connected around locating stud with a slice companion flange wherein, it passes opening slot and nut and screws and can play fastening effect, two flanges are tightened together, when opening, only need the several pitch of nut counterrotating, nut and pad and flange are broken away from, and it is fastening that the swivel joint bolt can make two flanges remove; Can finish the fastening of a bolt otherwise also only need rotate several pitch, can realize that flange opens soon, convenient and swift, time saving and energy saving.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a flange fastening structure assembling schematic representation described in the utility model;
Fig. 2 is Fig. 1 left view.
Among the figure:
1,2, flange; 3, swing bolt; 4, pad; 5, nut; 6, support plate; 7, locating stud.
Embodiment
Fig. 1, Fig. 2 diagram has provided flange fastening structure assembling schematic representation described in the utility model, and flange 1 is formed companion flange with flange 2, just determines to select board-like or two kinds of forms of long-neck butt joint according to pressure, adopts plate-type flange in the present embodiment.
Corresponding each fastening structure, edge joint weld at two flanges is connected to four support plates 6, form corresponding two opening slots up and down respectively, swing bolt 3 is installed in the open lower side groove by locating stud 7, when fastening, nut 5 is pressed on the side open groove support plate by pad 4, can realize fastening to flange by a plurality of this fastening structures that are distributed in the flange periphery.
By the rotatable characteristics of swing bolt, can realize the function of fast assembling-disassembling flange.
