Description
Technical field
The utility model relates to fastener field, particularly relates to a kind of vertical crane span structure seven word fastener.
Background technology
Crane span structure independently to set up, and also can be attached on various building and piping lane support, and embody simple, handsome in appearance, the flexible configuration of structure and the feature such as easy to maintenance, whole part all needs to carry out zinc-plated process, is arranged on the outer outdoor crane span structure of building.For cost of labor more and more higher at present, add manufacturing industry and compete increasing, for the producer that manufacturing industry is such, more and more value cost of labor and operating efficiency.At present, vertical bridge cover plate is fixed with colligation or male and female frame button, the mode of the production of vertical crane span structure is all adopt welding male and female frame button to obtain, not only to weld above crane span structure, and cover plate also needs welding, and install engineering construction personnel, maintenance, transport all wasted very large artificial, manufacturing cost and installation cost, need to weld for crane span structure manufacturer, loss is artificial, the electricity charge and mechanically to take, and very unsightly.
Utility model content
To the present situation of above-mentioned prior art, technical problem to be solved in the utility model is the vertical crane span structure seven word fastener providing a kind of cost low and easy for installation.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of vertical crane span structure seven word fastener, comprise locking arm, described locking arm lower end is connected with clevis arm by transition muscle, crotch arm is provided with inside described clevis arm, described locking arm is provided with fixing hole, is provided with fixed screw in described fixing hole.
Further, described locking arm comprises straight-arm and forearm.
Further, in 90 degree between described straight-arm and described forearm, the coupling mechanism force of 90 degree is best.
Compared with prior art, the utility model has the advantage of: the utility model is by arranging vertical locking arm and crotch arm, making between crane span structure body and bridge cover plate can not transverse shifting, by arranging fixed screw, make crane span structure body and bridge cover plate more fastening, the utility model is reasonable in design, can large-scale promotion.
Accompanying drawing explanation
Fig. 1 is a kind of vertical crane span structure seven word fastener structures schematic diagram of the utility model;
Fig. 2 is a kind of vertical crane span structure seven word fastener fundamental diagram of the utility model;
Fig. 3 is a kind of vertical crane span structure seven word fastener operation principle Local map of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of vertical crane span structure seven word fastener, comprise locking arm 1, described locking arm 1 lower end is connected with clevis arm 3 by transition muscle 2, is provided with crotch arm 4 inside described clevis arm 3, and described locking arm 1 is provided with fixing hole 5, fixed screw 6 is provided with in described fixing hole 5, described locking arm 1 comprises straight-arm 7 and forearm 8, and in 90 degree between described straight-arm 7 and described forearm 8, the coupling mechanism force of 90 degree is best.
Shown in Fig. 2-3, carry out operation principle explanation:
Vertical crane span structure is made up of two parts, be respectively crane span structure body 9 and bridge cover plate 10 two pieces, when installing, first crane span structure body 9 is installed, again bridge cover plate 10 is arranged on crane span structure body 9, vertical crane span structure is general all in the electric hoistway of building, and bridge cover plate 10 relies on bridge cover plate 10 itself stressed to support, when using seven word fasteners, first at crane span structure body 9 upper punch square hole 11, again the crotch arm 4 of seven word fasteners is stretched in square hole 11, press power is carried out again by 6 pairs of bridge cover plates of the fixed screw on seven word fasteners 10, be fixed and do not allow bridge cover plate 10 loosen.
Compared with prior art, the utility model has the advantage of: the utility model is by arranging vertical locking arm and crotch arm, making between crane span structure body and bridge cover plate can not transverse shifting, by arranging fixed screw, make crane span structure body and bridge cover plate more fastening, the utility model is reasonable in design, can large-scale promotion.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technical scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment technical scheme of the utility model.
