Description
Technical field
The utility model relates to a kind of pedal for escalator with disposable check bolt, belongs to staircase technical field.
Background technology
Staircase is widely used in the crowded occasion such as megastore, activity centre, and therefore the security performance of staircase is most important. Entrance and exit place at staircase is provided with pedal for escalator, and the below of pedal for escalator is the position at elevator motor place, once pedal for escalator does not install, tends to cause the huge injury of victim's person. And existing pedal structure is simple, only depend on and be bolted on truss, there is larger potential safety hazard.
Utility model content
The purpose of this utility model is, a kind of pedal for escalator with disposable check bolt is provided. The utility model can be fixed together pedal and truss securely, and double-screw bolt of the present utility model is disposable check bolt, has avoided the potential safety hazard that does not tight a bolt and cause in the time that pedal is safeguarded.
The technical solution of the utility model: a kind of pedal for escalator with disposable check bolt, comprise pedal, the side frames of pedal is located on truss, and the surrounding of pedal fixes through check bolt and truss; Described check bolt comprises nut, and nut below is screw rod, and screw rod top is provided with widely-pitched screw thread, and screw rod below is provided with narrow pitch screw thread; On described truss, offer screwed hole, check bolt matches with screwed hole.
In the above-mentioned pedal for escalator with disposable check bolt, the end of described screw rod is provided with end external screw thread, and nut inside is provided with and the internal thread of holding screw thread to match, and end external screw thread is meshed with internal thread.
Compared with prior art, the utility model fixes pedal and truss by check bolt, and the screw rod of check bolt top is widely-pitched screw thread, screw rod below is narrow pitch screw thread, in the time that screw rod is screwed into the screwed hole on truss, when widely-pitched screw thread engages with screwed hole, widely-pitched screw thread is destroyed, while back-outing again check bolt, check bolt has just been scrapped, in the time again twisting bolt, need to upgrade new bolt, therefore avoid bolt to reuse the potential safety hazard that the bolt causing is not tightened or skidded, improve the security using. As further preferred, be provided with end external screw thread in the end of screw rod, nut inside is provided with the internal thread matching with end external screw thread, be screwed at screw rod after the screwed hole of truss, nut is back-outed from screw rod, further avoided check bolt loosening or come off and people is the problem loosering a bolt.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of check bolt.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment: a kind of pedal for escalator with disposable check bolt, form as depicted in figs. 1 and 2, comprise pedal 1, the side frames of pedal 1 is located on truss 2, and the surrounding of pedal 1 fixes through check bolt 3 and truss 2; Described check bolt 3 comprises nut 4, and nut 4 belows are screw rod 5, and screw rod 5 tops are provided with widely-pitched screw thread 6, and screw rod 5 belows are provided with narrow pitch screw thread 7; On described truss 2, offer screwed hole 8, check bolt 3 matches with screwed hole 8. The end of described screw rod 5 is provided with end external screw thread 9, and nut 4 inside are provided with the internal thread 10 matching with end external screw thread 9, and end external screw thread 9 is meshed with internal thread 10. The utility model fixes pedal and truss by check bolt, and the screw rod of check bolt top is widely-pitched screw thread, screw rod below is narrow pitch screw thread, in the time that screw rod is screwed into the screwed hole on truss, when widely-pitched screw thread engages with screwed hole, widely-pitched screw thread is destroyed, while back-outing again check bolt, check bolt has just been scrapped, in the time again twisting bolt, need to upgrade new bolt, therefore avoid bolt to reuse the potential safety hazard that the bolt causing is not tightened or skidded, improved the security using. As further preferred, be provided with end external screw thread in the end of screw rod, nut inside is provided with the internal thread matching with end external screw thread, is screwed into after the screwed hole of truss at screw rod, nut is back-outed from screw rod, further avoided the problem that check bolt is loosening or come off.
