The connection structure of corner bracket and roller shaft.
The object of the present invention is achieved like this：
A kind of connection structure of escalator tripod and roller shaft, it is characterised in that it includes hollow dormant bolt, empty
Nuts and washers is rotary on heart dormant bolt, hollow dormant bolt one end is equipped with nut, the other end interpolation of hollow dormant bolt
Enter to be free distention related to the heart pipe, hollow tube expansion tail end to be equipped with tube expansion head, be additionally provided with retainer ring on the hollow dormant bolt, retainer ring side is prolonged
Stretching has protrusion, and protrusion is equipped with limited block.
A kind of connection structure of escalator tripod and roller shaft as described above, it is characterised in that the tube wall of hollow tube expansion
It is provided with slot.
A kind of connection structure of escalator tripod and roller shaft as described above, feature are equipped with card on tube expansion head
Block, hollow dormant bolt are equipped with the card slot coordinated with fixture block.
The beneficial effects of the invention are as follows：
The present invention includes hollow dormant bolt, and hollow dormant bolt is equipped with nuts and washers, hollow dormant bolt one end
Being inserted into equipped with nut, in the other end of hollow dormant bolt is free distention related to the heart pipe, and hollow dormant bolt is sleeved on to the main shaft of tripod
On seat, the axle sleeve of spindle drum is made to be stuck between nut and retainer ring, then roller shaft is inserted into hollow dormant bolt and is inserted into
Into hollow tube expansion.It is simple in structure, it is at low cost, the manufacturing cost of escalator can be reduced, is connected firmly, will not be loosened, is filled
It is convenient for disassembly and assembly with convenience, facilitate repair.
