Furthermore, the circular arc connecting plate is arranged below the circular tube handrail.
Furthermore, the arc connecting plate is welded with the other end of the fixing plate.
Furthermore, one end of the fixing plate is fixedly connected with the elevator car wall plate through the matching of more than two groups of bolts and rivet nuts.
Furthermore, the arc connecting plate is fixed on the circular tube handrail through more than two set screws.
Furthermore, the more than two set screws are arranged at intervals along the axis direction of the circular tube handrail.
Further, the fixing plate is a V-shaped bending piece.
Further, the bending angle of the fixing plate is 45 degrees.
The utility model discloses a beneficial effect of an embodiment lies in: the arc connecting plate and the circular tube handrail are fixedly connected through a set screw by adopting a mode of directly installing in the elevator car, and the inner arc surface of the arc connecting plate is attached to the circular tube handrail and is changed from point contact of bolt connection into surface contact. Be provided with rivet nut on elevator car wallboard, through the bolt with rivet nut's cooperation will the fixed plate with elevator car wallboard fixed connection need not screw up the screw in the well of elevator car outside, directly fixes locking bolt in elevator car with the nut, has both practiced thrift manpower and installation time, has guaranteed construction safety again. The scheme has the advantages of simple structure, low manufacturing cost and high practical value, can realize standardized production, and shortens the installation period of the elevator.

Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments, and the following embodiments are used for illustrating the present invention, but do not limit the scope of the present invention.
Referring to fig. 1 to 3, one embodiment of the circular tube handrail fixing device for an elevator car includes a circular arc connection plate 110, a fixing plate 130, a rivet nut 150, a bolt 140, and a set screw 120. The rivet nut 150 is arranged on the elevator car wall plate 300, one end of the fixing plate 130 is fixedly connected with the elevator car wall plate 300 through the matching of more than two groups of bolts 140 and the rivet nut 150, the fixing of the fixing plate 130 and the elevator car wall plate 300 is realized by directly operating in the elevator car, and the operation is simple and safe. The arc connecting plate 110 is attached to the outer surface of the circular tube handrail 200 and fixed to the circular tube handrail 200 by the set screw 120, and the arc connecting plate 110 is fixedly connected to the other end of the fixing plate 130. The circular tube handrail 200 is stably contacted by surface contact with a simple structure in which the circular arc connecting plate 110 is additionally provided to the fixing plate 130. In a preferred embodiment, the arc connecting plate 110 is fixedly connected to the other end of the fixing plate 130 by welding.
In a preferred embodiment, the circular arc connecting plate 110 is disposed below the circular tube handrail 200, and is supported from the bottom of the circular tube handrail 200, so as to be more stable.
