Abstract
With a stair climbing trolley luggage for feet, formed by casing, telescopic lever, tripod roller and V-arrangement bracing frame, be characterized in that telescopic lever and bracing frame are all adjusted to different length by a pair of spring steel ball, the colonial need not waiting to meet height; V-arrangement bracing frame reduces the flecition of gravity to pull bar in order to prop case and bag, also alleviates stressed to human arm simultaneously; Tripod roller not only can be used for level land, is also applicable to the country lanes of hollow, and capable of climbing stairs.The utility model design science, meets human engineering mechanics's structure, makes material and is easy to get, and technique is simple, easy to use, and adaptation population is extensive, and market prospects are good.
Description
One, technical field
The utility model relates to the technical field of the convenient use of a kind of tie bar type traveling case bag, is specifically related to a kind of technical field of not only having protected pull bar not to be bent but also to possess the luggage of and climb stepfunction bad in road conditions in using.
Two, background technology
Along with social development and progress, movement of population is more and more by traffic easily, and the luggage of rod-pulling type is the article storing equipment that people go out first-selected.In the time of mobile case and bag, people are as long as hold gently pull bar and just can make case and bag roll on the ground, laborsaving convenience.But the problem that in use we run into is in the time that case and bag are heavier, pull for a long time and repeatedly case and bag, the bending that its pull bar will be gradually, flexible with regard to dumb even block draw motionless; The wheel that common case and bag are installed is smaller, just needs people portable or pickaback in the time crossing step or go upstairs, and will be a thing very laboriously there is no to move larger case and bag in the commercial residential building of elevator and office buildings.In addition, the wheel of case and bag is little, on the bad ground of vast rural area road conditions, pulls case and bag also to bother very much, is a huge colony and the civilian worker that goes out uses trolley luggage.Through patent retrieval, although there are nearly ten patents to be the case and bag design about stair climbing at present, useful caterpillar, while often use, have some setbacks, easily damage; Useful four-wheel rolls, useful three-wheel or two wheel drive, but that it takes turns sub-volume is larger, and case and bag are put unsafe, take up space many; Also have star wheel is designed to dismantled replacing structure, and it uses also inconvenient.Do not find at present the trolley luggage that contains bracing frame.Use the people of trolley luggage all to know, the place that case and bag the most easily go wrong be exactly pull bar flexible pull up very hard and dumb case and bag of roller draw motionless, roller also usually damage drop.The utility model has merged physics and ergonomic is gained knowledge; design one and protected pull bar with feet; thereby deal with uneven road surface with tripod roller and play the trolley luggage of protecting wheel, be convenient for people to tackle multiple environment, extend the service life of case and bag.
Three, utility model content
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, design science, practical, capable of climbing stairs, the case and bag that also can pull at uneven road surface.
The utility model solves the technical scheme that its technical problem adopts: a kind of stair climbing trolley luggage with feet, comprises casing, telescopic lever, tripod roller, V-arrangement bracing frame.Its feature is that tripod roller meets case and bag and advances or climb step stair etc. at uneven road surface; V-arrangement bracing frame is propped first case and bag weight protection telescopic lever and is prevented flexural deformation, and another is to be stretched and coordinated telescopic lever adjustment length to meet different height persons' laborsaving and comfortable use by feet.
As the further improvement of the technical program, described telescopic lever and the equal adjustable length of V-arrangement bracing frame, they are all made up of inner and outer tubes, and inner tube bottom is provided with two steel balls with spring, and outer tube has some steel balls hole, and its aperture ratio steel ball is smaller.When pull bar, steel ball under tension can depart from aperture, and to draw direction motion, during to next aperture, just automatic spring locks pull bar.This structure adopts two steel balls steady braces simultaneously, can make pull bar more firmly, do not rock.
As the further improvement of the technical program, two feets of described V-arrangement bracing frame are contained in the movable hinge of feet, also can adopt U-shaped support latch closure at the case and bag back side.In the time of the lighter weight of case and bag, V-arrangement bracing frame is attached to case and bag bottom, and two universal wheel is as the pulley of case and bag; If just open V-arrangement bracing frame when case and bag are heavier with performance supporting role.
Be further improvement as the technical program, described tripod roller two-wheeled spacing, in 18cm left and right, is less than the standard of 17.5cm to meet common building residence stairs shoulder height.Tripod roller not the used time be to be fixed on shaft position in case and bag side, while needs first loosening fixed chuck tripod roller to be moved to from the guide rail of fixation steel plate to case and bag bottom fastening, utilize two wheels wherein at ground surface or stair activity.
The beneficial effects of the utility model are design science, rational in infrastructure, meet base of principle of human engineering, and by adjusting yoke length, the people of different heights can find the most comfortable, labour-saving case and bag and ground angle, as made to measure; The support of V-arrangement bracing frame to case and bag, has reduced the downward pulling force of case and bag weight to pull bar, prevents pull bar flexural deformation, alleviate people on hand firmly; Between tripod roller and universal wheel, can be used alternatingly, also can synchronously use, conversion is convenient, and tripod roller wherein can move to along steel plate guide rail in the middle slotted eye of case and bag side in used time not, guaranteed to occupy space when case and bag are piled up less.The utility model has been realized the flexible conversion of universal wheel and tripod roller, both can move for level land, also can adapt to potted road surface motion, can also climbing stair step, bring great convenience to people's Portable box bag of going out.
