Abstract
The utility model relates to a back-rest for passengers in a train. The entire cushion is inflatable type, the upper part of the cushion is a star-shaped head pillow cushion, the middle part is a square neck cushion, and the lower part is a concave shoulder, back, and waist cushion. All the cushions are communicated. The cushion body is also provided with an air charging port and a fixing strap. The product has foldable operation, convenient carrying, reasonable design, convenient use, simple structure, and low cost, and can bring comfort for passengers who travel with hard seats in a train.
Description
The utility model belongs to motor turning structure applications technical field, and detailed a kind of transport trolley wheel shaft wide-angle that is meant turns to control structure.
General mountain area farming thing is for conveniently moving operation, common mode is mostly adopted with transport trolley (being commonly called as Boston ivy) and is carried at present, present being seen transport trolley wheel axle steer control structure all adopts the joint mode that is coupling, therefore about about 30 degree of its rotating shaft steering locking angle degree, so travel when the bigger sheep intestines path of mountain area camber, usually can't once turn smoothly, and need to cooperate the reversing mode just can finish the transformation operation repeatedly to pour into, if when running into the bigger turning of the gradient, then seem quite dangerous as the turning mode that falls back repeatedly to advance.
Therefore, the purpose of this utility model is: provide a kind of axletree wide-angle of moving to turn to control structure, its wheel shaft can wide-angle be turned to.
The utility model provides the differential assembly of the takeoff output of this two steering wheel shafts group to be formed by the two identical wide-angle steering wheel shaft groups of symmetry and one.The horizontal rotating shaft that connects wheel disconnects with output shaft and separating, and each steering wheel shaft group has a upright steering controlling shaft, and its upper and lower side respectively is provided with a crowngear 12, and clamshell 13 is carried out and covered at the upright steering controlling shaft and the periphery of crowngear about it.One horizontal rotating shaft and axle sleeve cooperate clamshell 25 to be coupling in the side of upright steering controlling shaft, and rotating shaft the inner is provided with the gear toe joint of gear and upright steering controlling shaft bottom.Output shaft is not held gear 12 toe joints that are provided with gear 34 and are positioned at upright actuating spindle upper end.The bearing circle operator link drives clamshell 25, and laterally rotating shaft can be around upright actuating spindle rotation 0-360 degree.Upright steering controlling shaft is positioned at output shaft
It is sealed polyethylene plastic that this product adopts internal layer, and skin is the double-layer composite material of syntheticfibres, requires to have certain air-tightness and Dent resistance.During use, find inflation inlet, after treating that gas is full of, be put in lazyback, the bottom is supported by vehicle seat, the passenger is affixed on the back spill shoulder of pad, the back of the body, two protrusions of waist bolster, this moment head, neck, shoulder, the back, waist all obtains the support and the buffering of back cushion corresponding position, and increased the degree of dip of backrest, the passenger leans on thereon, and upper body is natural relaxation and faces upward the sitting posture gesture, and head is fixed, can not droop or be partial to phenomenon such as both sides because of occurring head after sleeping, breathe unimpeded, no any discomfort sense, waist is fastened clamping band, can prevent train again owing to jolting or stop suddenly phenomenons such as causing air cushion and back offset, so this product have extraordinary practicality and safety.Not the time spent, only need open inflation inlet, gas is drained, folding keeping well carried very convenient.
