Abstract

The utility model belongs to the technical filed of machinery, particularly relates to a door pivot fastener of a protective door of a passenger and cargo elevator for construction, which comprises a door pivot. The door pivot is connected with a connecting piece through threads, and two opening-closing pieces are hinged to the connecting piece and connected with a scaffold steel pipe through bolts. The door pivot is fastened on the fastener through the bolts, and then the fastener is fastened on the scaffold steel pipe, thereby realizing fixation of the door pivot and the scaffold steel pipe. The door pivot fastener of the protective door of the passenger and cargo elevator for the construction is simple in structure, good in practicability and convenient to use and dismount, does not damage the scaffold steel pipe, and saves construction cost.

Description

Construction personnel selection goods elevator protective door door-hinge fastener

Technical field:

The utility model belongs to field of mechanical technique, is specifically related to a kind of construction personnel selection goods elevator protective door door-hinge fastener.

Background technology:

In building construction process, the cage that reaches people's goods elevator that the goods vertical transport uses for the workman up and down is concordant with building scaffold outward, therefore just protective door need be installed on scaffold, at present, the installation of protective door is that door-hinge is welded in the vertical rod of scaffolding steel pipe, then protective door is hung on the door-hinge, this installation method all needs to be welded to connect at every turn, field operation needs welding gear, and construction workman's work capacity is big, time-consuming, trouble is installed, and when construction finishes needs dismounting door-hinge, door-hinge need be cut away, damage steel pipe easily, reduce the load-carrying properties of steel pipe, for the use of later steel pipe brings potential safety hazard, have a strong impact on the service life of steel pipe, increase construction cost.

The utility model content:

In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of construction personnel selection goods elevator protective door door-hinge fastener, and it is that door-hinge is locked on the fastener by bolt, then fastener is locked on the scaffolding steel pipe, thereby realize door-hinge and scaffolding steel pipe are fixed, it is simple in structure, and is practical, easy to use, easy accessibility can not damage scaffolding steel pipe, saves construction cost.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of construction personnel selection goods elevator protective door door-hinge fastener, wherein: it comprises door-hinge, and door-hinge is connected with attaching parts by screw thread, is hinged with two opening and closing parts on the attaching parts, and two opening and closing parts are connected with scaffolding steel pipe by lock bolt.

The beneficial effects of the utility model are:

1, the utility model is that door-hinge is locked on the fastener by bolt, then fastener is locked on the scaffolding steel pipe, thereby realizes door-hinge and scaffolding steel pipe are fixed; ,

2, the utility model is simple in structure, and is practical, easy to use, and easy accessibility can not damage scaffolding steel pipe, saves construction cost.

Description of drawings:

Fig. 1 is the utility model structural representation.

The specific embodiment:

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, a kind of construction personnel selection goods elevator protective door door-hinge fastener, it comprises door-hinge 1, door-hinge 1 is connected with attaching parts 4 by screw thread, be hinged with two opening and closing parts 2 on the attaching parts 4, two opening and closing parts 2 all can be around its jointed shaft 5 rotations, and two opening and closing parts 2 are connected with scaffolding steel pipe by lock bolt 3.

During use, door-hinge 1 is installed in the bolt hole of attaching parts 4, with jam nut 6 lockings, unclamp the lock bolt 3 of opening and closing part 2, the utility model is enclosed within outside the scaffolding steel pipe, at last lock bolt 3 is tightened, can realize door-hinge 1 is fixed on the scaffolding steel pipe.

Be noted that, the above embodiment is to the explanation of technical solutions of the utility model and unrestricted, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
