Description
Technical field
The utility model relates to a kind of parts of attached cable crane span structure, specifically a kind of windproof buckle for attached cable crane span structure cell body and cover plate.
Background technology
Cable testing bridge has flexible configuration and the feature such as easy to maintenance, and be therefore widely used in defeated, distribution industry, common cable testing bridge generally includes cell body and cover plate, and after cable laying completes, cover plate is fastened on cell body upper port, and needs cover plate and cell body to fix.Common fixed form has card slot type and withholds formula two kinds of methods.Card slot type is fixedly process corresponding draw-in groove respectively at cell body side plate and cover plate both sides in advance, when crane span structure is installed, by applying external force, cover plate is fastened on cell body, the method is high to requirement on machining accuracy, coordinate tension to increase installation difficulty, cross pine and can make excesssive gap, easily come off and can not meet technical requirement.The formula of withholding a pair is withheld the correspondence position being arranged on cell body and cover plate respectively, withholds and fixed by self-tapping screw, and the method Problems existing is, it is just corresponding to be difficult to guarantee two positions of withholding, and self-tapping screw easily comes off in addition.
Application number is disclose a kind of hook for cable bridge rack in the patent of 200820076965.9, fixed by the mode of hook, in use operator need manual override to link up with elastic force by fastened with hook in cell body and cover plate junction, operation require great effort very much, fasten difficulty large.And owing to being point cantact between hook and cover plate, in the environment having wind, easily there is vibration and cause hook to come off in cover plate.
Summary of the invention
The purpose of this utility model is to provide a kind of windproof buckle for attached cable crane span structure cell body and cover plate.Simple to operate, be not easy to come off.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of windproof buckle for attached cable crane span structure cell body and cover plate, be made up of " 7 " font sheet metal and bolt, described " 7 " font sheet metal comprises side plate sticking part, evagination connecting portion and cover plate attaching part, the hook that punching press is formed is provided with at described side plate sticking part place, described cover plate attaching part is provided with screwed hole, and described screwed hole coordinates with bolt.
The beneficial effects of the utility model are: the utility model structure is simple, easy to use, and rear and cell body and cover plate the contact area of installation is comparatively large, is not easy to come off, is particluarly suitable for using when outside cable crane span structure is installed.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is perspective view of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Fig. 3 is the utility model using state structural representation.
In figure: 1-" 7 " font sheet metal; 11-side plate sticking part; 12-evagination connecting portion; 13-cover plate attaching part; 14-hook; 2-bolt; 3-cell body; 4-cover plate.
Embodiment
As shown in Figure 1, 2, a kind of windproof buckle for attached cable crane span structure cell body and cover plate, be made up of " 7 " font sheet metal 1 and bolt 2, described " 7 " font sheet metal 1 comprises side plate sticking part 11, evagination connecting portion 12 and cover plate attaching part 13, the hook 14 that punching press is formed is provided with at described side plate sticking part 11 place, described cover plate attaching part 13 is provided with screwed hole, and described screwed hole coordinates with bolt 2.
Described evagination connecting portion 12 is mutually vertical with side plate sticking part 11, and described side plate sticking part 11 is parallel with evagination connecting portion 12, offsets in the horizontal direction relative to evagination connecting portion 12 to the side being provided with cover plate attaching part 13.Thus making sheet metal be " 7 " font, the space that the inner side of evagination connecting portion 2 exists can containment cap edges of boards angle, avoids interfering with cover plate corner.
Using state as shown in Figure 3, cover plate 4 is fastened on cell body 3, then hook 14 is inserted in slotted eye that cell body 3 sidewall pre-sets, screwing bolts 2, bolt lower end is made to withstand cover plate 4, and apply certain pretightning force, thus ensure that cover plate 2 and cell body 3 closely fasten, want large because bolt 2 and the relative buckle of contact area on cover plate 4 top connect, and side plate sticking part 3 and cell body side sheet room are face contacts, not easily deflect, when outdoor wind-force is larger, also can not come off.Thus play anti-wind action, and simple to operation.
