Abstract
The invention discloses an arrangement structure of a handrail in a lift car. When the handrail is installed, a first threaded fastener is screwed in a nut, a second threaded fastener penetrates into a connecting nut, the second threaded fastener is screwed into a threaded hole in the end face of the handrail, the handrail is connected with the rotatable connecting nut through the second threaded fastener, and the connecting nut is rotated, thereby fastening the connecting nut and the first threaded fastener and realizing the installation of the handrail onto the wall of the lift car; and when the handrail is dismounted, the connecting nut is detached from the first threaded fastener so as to demount the handrail from the wall of the lift car, and then the second threaded fastener is loosened, so that the handrail is separated from the connecting nut, and the handrail can be maintained and replaced. The installation and demounting of the handrail can be carried out in the lift car, and working personnel can operate outside the lift car without entering a lift well, thereby avoiding safety accidents, reducing the workload for installing and demounting the handrail, and facilitating the maintenance and replacement of the handrail.

Technical field
The present invention relates to the structure that is provided with of the interior handrail of car.
Background technology
In car, existing handrail is provided with in the structure, the end of handrail is fixed with bolt, on the sedan-chair wall, offer the handrail mounting hole, bolt on the handrail inserts the handrail mounting hole from cab interior, at the outside fastening nut of car, realizes the installation of handrail on the sedan-chair wall then, when needs dismountings handrail, then the staff must arrive the car outside and unclamps nut.Car is outside could be implemented because the Assembly ﹠Disassembly of handrail must arrive, and causes the work capacity of handrail Assembly ﹠Disassembly big, troublesome poeration, and cause safety misadventure easily.
Summary of the invention
The purpose of this invention is to provide the handrail that in car, just can carry out the Assembly ﹠Disassembly of handrail structure is set.
For achieving the above object, the technical solution used in the present invention is: handrail is provided with structure in the car, comprise the sedan-chair wall, be removably disposed in the handrail on the described sedan-chair wall, offer the handrail mounting hole on the described sedan-chair wall, offer tapped bore on the end face of described handrail, described handrail the nut that structure also comprises the position of the above the handrail mounting hole of the outside that is fixed on described sedan-chair wall is set, both ends be provided with outside thread and wherein an end can screw in first threaded fasteners the described nut from the inside of described sedan-chair wall, one end can be spun on radially to extend internally on the other end of described first threaded fasteners and at the other end and form the radially coupling nut of rib, head can keep off in the inboard of described radially rib and screw thread body portion can pass described coupling nut with second threaded fasteners in the tapped bore that screws in described handrail end face, in the head of described second threaded fasteners retaining inboard of rib radially in described coupling nut, and the screw thread body portion of described second threaded fasteners passes described coupling nut, when screwing in the tapped bore of described handrail end face, described coupling nut is with respect to the rotatable setting of described second threaded fasteners.
Preferably, in the head of described second threaded fasteners retaining inboard of rib radially in described coupling nut, and when the screw thread body portion of described second threaded fasteners screwed in the tapped bore of described handrail end face, described coupling nut contacted rotationally with described handrail.
Preferably, described first threaded fasteners adopts bolt, and described bolt comprises that outer peripheral face is provided with screw thread and is used for the head that matches with described coupling nut, the screw thread body portion that can screw in nut from the inside of described sedan-chair wall.
Preferably, offer handle hole on the end face of described head.
Preferably, described second threaded fasteners adopts bolt.
Because the utilization of technique scheme, the present invention compared with prior art has following advantage: when handrail is installed, first threaded fasteners is screwed in the nut, second threaded fasteners is penetrated the coupling nut, screw in the tapped bore of handrail end face, connecting rotating coupling nut by second threaded fasteners on the handrail, nut then is rotationally connected, realize the fastening of the coupling nut and first threaded fasteners, then realized the installation of handrail on the sedan-chair wall; When the dismounting handrail, the coupling nut is separated from first threaded fasteners, be about to handrail and disassemble from the sedan-chair wall, unclamp second threaded fasteners then, handrail can be separated with the coupling nut, then can repair or replace handrail.The Assembly ﹠Disassembly of this handrail all can carry out at cab interior, and the staff need not to enter elevator hoistways and operates in the car outside, has avoided safety misadventure, has reduced the work capacity of the Assembly ﹠Disassembly of handrail, makes things convenient for the maintenance and the replacing of handrail.
Description of drawings
Accompanying drawing 1 is a cross-sectional schematic of the present invention.
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to shown in Figure 1, handrail is provided with structure in the car, comprise sedan-chair wall 10, be removably disposed in the handrail 4 on the sedan-chair wall 10, nut 9, first threaded fasteners 1, second threaded fasteners 5, the coupling nut 2, offer the handrail mounting hole on the sedan-chair wall 10, nut 9 is fixed on the position of the handrail mounting hole on the outside of sedan-chair wall 10, be provided with outside thread on the both ends of first threaded fasteners 1, the handrail mounting hole can be passed from the inside of sedan-chair wall 10 in one end of first threaded fasteners 1, screw then in the nut 9, realize the fastening of first threaded fasteners 1 and nut 9, the other end of first threaded fasteners 1 cooperates with coupling nut 2, first threaded fasteners 1 can adopt bolt, and this bolt comprises that outer peripheral face is provided with screw thread and is used for the head 8 that matches with coupling nut 2, can screw in the screw thread body portion 7 the nut 9 from the inside of sedan-chair wall 10.Offer tapped bore on the end face of handrail 4.An end of coupling nut 2 can be tightened on the head 8 of first threaded fasteners 1, the other end extends radially inwardly in the end face upper edge and forms radially rib 11, second threaded fasteners 5 is when passing coupling nut 2, the head 6 of second threaded fasteners 5 can retaining in the inboard of rib 11 radially, the screw thread body portion 3 of second threaded fasteners 5 passes coupling nut 2, can screw in the tapped bore of handrail 4 end faces, second threaded fasteners 5 can adopt bolt, can connect coupling nut 2 and handrail 4 by second threaded fasteners 5, when second threaded fasteners 5 connects coupling nut 2 and handrail 4, coupling nut 2 is with respect to second threaded fasteners, 5 rotatable settings, and coupling nut 2 contacts rotationally with handrail 4.When handrail is installed, first threaded fasteners 1 is screwed in the nut 9, second threaded fasteners 5 is penetrated coupling nut 2, screw in the tapped bore of handrail 4 end faces, connecting rotating coupling nut 2 by second threaded fasteners 5 on the handrail 4, the nut 2 that then is rotationally connected is realized the fastening of the coupling nut 2 and first threaded fasteners 1, has then realized the installation of handrail 4 on sedan-chair wall 10; When the dismounting handrail, coupling nut 2 is separated from first threaded fasteners 1, be about to handrail 4 and disassemble, unclamp second threaded fasteners 5 then from sedan-chair wall 10, handrail 4 can be separated with coupling nut 2, then can repair or replace handrail 4.The Assembly ﹠Disassembly of this handrail all can carry out at cab interior, and the staff need not to enter elevator hoistways and operates in the car outside, has avoided safety misadventure, has reduced the work capacity of the Assembly ﹠Disassembly of handrail, makes things convenient for the maintenance and the replacing of handrail.
