Abstract

The invention discloses a sleeper made of magnesium alloy for a trolley coach. The sleeper includes a sleeper body, and a rotary shaft base fixed with two side wall bodies; a guard rail and a handle are installed on the sleeper body; the sleeper body includes a framework made of magnesium alloy; a rotary shaft passes between the framework made of magnesium alloy and the rotary shaft base; a positioning shaft is arranged on the framework made of magnesium alloy; a compression spring is sleeved with the positioning shaft; a positioning hole is arranged on the rotary shaft base; the positioning shaft is connected with the handle; and fit positioning between the positioning shaft and the positioning hole is realized through controlling the positioning shaft to retract by the handle. The sleeper made of magnesium alloy for the trolley coach has the advantages of higher intensity and rigidity, better electromagnetic shielding performance and damping capacity, perfect casting property, good machinability, low processing cost, strong resistance to corrosion, easy recycle, etc. The sleeper made of magnesium alloy for the trolley coach is rotated through the rotary shaft and positioned through the positioning shaft, and the use is convenient, laborsaving, safe and reliable.

Description

technical field [0001] The invention relates to a sleeping berth of a rail passenger car. Background technique [0002] The sleeping berths used in existing rail vehicles are generally carbon steel sleeping berths. The sleeping berths with this structure have the disadvantages of heavy weight, loud noise, and large vibration; device, there are unsafe factors; in addition, the sleeper with this structure, the protective railing is made of carbon steel skeleton with plastic coating, which needs to be pulled up when folding, and then folded again. The disadvantages are: heavy weight; when the sleeper is placed horizontally, its The height is about the position of the chest of the passenger, which has exceeded the elbow joint. At this height, it is difficult for the passenger to pull up the railing with force, and it is not easy to fold. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to overcome the ...
