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 arranges of the interior handrail of car.
Background technology
In car, existing handrail arranges in the structure, the end of handrail is fixed with bolt, offer the handrail mounting hole at the sedan-chair wall, bolt on the handrail inserts the handrail mounting hole from cab interior, then at the outside fastening nut of car, realizes the installation of handrail on the sedan-chair wall, 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 large, troublesome poeration, and easily cause safety misadventure.
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 arranges 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, be provided with on the both ends outside thread and wherein an end can screw in from the inside of described sedan-chair wall the first threaded fasteners the described nut, one end can be spun on radially to extend internally on the other end of described the 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 section can pass described coupling nut with the second threaded fasteners in the tapped bore that screws in described handrail end face, in the head of described the second threaded fasteners gear inboard of rib radially in described coupling nut, and the screw thread body section of described the second threaded fasteners passes described coupling nut, when screwing in the tapped bore of described handrail end face, described coupling nut rotatably arranges with respect to described the second threaded fasteners.
Preferably, in the head of described the second threaded fasteners gear inboard of rib radially in described coupling nut, and when the screw thread body section of described the second threaded fasteners screwed in the tapped bore of described handrail end face, described coupling nut contacted rotationally with described handrail.
Preferably, described the first threaded fasteners adopts bolt, and described bolt comprises that being provided with screw thread on the outer peripheral face is used for the head that matches with described coupling nut, the screw thread body section that can screw in from the inside of described sedan-chair wall nut.
Preferably, offer handle hole on the end face of described head.
Preferably, described the second threaded fasteners adopts bolt.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages: when handrail is installed, the first threaded fasteners is screwed in the nut, the second threaded fasteners is penetrated the coupling nut, screw in the tapped bore of handrail end face, connecting rotating coupling nut by the second threaded fasteners on the handrail, then be rotationally connected nut, realize the fastening of coupling nut and the first threaded fasteners, then realized the installation of handrail on the sedan-chair wall; When the dismounting handrail, the coupling nut is separated from the first threaded fasteners, be about to handrail and disassemble from the sedan-chair wall, then unclamp the second threaded fasteners, 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 maintenance and the replacing of handrail.
Description of drawings
The specific embodiment
Further set forth structure of the present invention below in conjunction with accompanying drawing.
Referring to shown in Figure 1, handrail arranges structure in the car, comprise sedan-chair wall 10, be removably disposed in the handrail 4 on the sedan-chair wall 10, nut 9, the first threaded fasteners 1, the 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 the first threaded fasteners 1, the handrail mounting hole can be passed from the inside of sedan-chair wall 10 in one end of the first threaded fasteners 1, then screw in the nut 9, realize the fastening of the first threaded fasteners 1 and nut 9, the other end of the first threaded fasteners 1 cooperates with coupling nut 2, the first threaded fasteners 1 can adopt bolt, and this bolt comprises that being provided with screw thread on the outer peripheral face is used for the head 8 match with coupling nut 2, can screw in from the inside of sedan-chair wall 10 the screw thread body section 7 the nut 9.Offer tapped bore on the end face of handrail 4.An end of coupling nut 2 can be tightened on the head 8 of the first threaded fasteners 1, the other end radially extends internally on end face and forms radially rib 11, the second threaded fasteners 5 is when passing coupling nut 2, the head 6 of the second threaded fasteners 5 can gear in the inboard of rib 11 radially, the screw thread body section 3 of the second threaded fasteners 5 passes coupling nut 2, can screw in the tapped bore of handrail 4 end faces, the second threaded fasteners 5 can adopt bolt, can connect coupling nut 2 and handrail 4 by the second threaded fasteners 5, when the second threaded fasteners 5 connects coupling nut 2 and handrail 4, coupling nut 2 rotatably arranges with respect to the second threaded fasteners 5, and coupling nut 2 contacts rotationally with handrail 4.When handrail is installed, the first threaded fasteners 1 is screwed in the nut 9, the 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 the second threaded fasteners 5 on the handrail 4, then be rotationally connected nut 2, realize the fastening of coupling nut 2 and the first threaded fasteners 1, then realized the installation of handrail 4 on sedan-chair wall 10; When the dismounting handrail, coupling nut 2 is separated from the first threaded fasteners 1, be about to handrail 4 and disassemble from sedan-chair wall 10, then unclamp the second threaded fasteners 5, 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 maintenance and the replacing of handrail.
