Abstract
The utility model relates to a force-saving stairs climbing handcart, which is a cart for people with heavy going up stairs, can also be uses on the flat ground as a utility cart. The utility model counts a car body as a power arm, a car wheel and a purpose-made supporting wheel respectively as an ever-changing lever pivot in the process of going up stairs. People who climbs floor manipulate a handle bar and a subsidiary pressure lever to transform lever pivot, climbs stairs with goods and labor saving basis on lever principle. The utility model has the advantages of simple structure and multi-function.
Description
It is to help others to take the daily dolly tool of weight going upstairs that gaholder of the present utility model is climbed the building Labour-saving car.
The people who lives high building feels embarrassed for heavy burden thing going upstairs deeply, and also have similar patented product to occur more, desires to ask the solution of this problem, but cut both ways after deliberation.
The purpose of this utility model provides a kind of according to lever principle, and car body and wheel are considered as the arm of force and fulcrum respectively, solves the tired a kind of new design plan that the building is climbed in heavy burden by the manipulation of the arm of force and the conversion of fulcrum.
Gaholder of the present utility model is climbed the structure diagram of application example of building Labour-saving car referring to accompanying drawing:
1. collet side arm, 2. axletree, 3. collet after-frame, 4. handlebar, 5. auxilliary depression bar, 6. vehicle frame, 7. extension spring, 8. support wheel, 9. spacer frame, 10. strut bar, 11. wheels, 12. front racks, 13. poles.
It is wide less than the one-level stair that wheel (11) and support wheel (8) spacing are about 24Cm; Spacer frame (9) is the acute angle weldering extremely in the lower edge of vehicle frame (6) relevant position, and its lower end is provided with the spacer slideway; One terminal bolt of strut bar (10) is hinged on the relevant position of vehicle frame (6), and other end device has support wheel (8), and whole strut bar (10) can slide in the spacer slideway of spacer frame (9) by pulling and supporting of extension spring (7); Collet side arm (1), collet after-frame (3), front rack (12) weldering extremely on the relevant position of vehicle frame (6), can be placed weight; Handlebar (4) is connection types alive with vehicle frame and keeps 140 ° of angle position relations; Crossbeam is provided with the plug-in auxilliary depression bar (5) that is 50 ° of angles with the handlebar plane, can exempt the bend over hard work of operation of operator in the time of upstairs.
This gaholder is climbed the building Labour-saving car when placing on the level land, wheel (11) and support wheel (8) land simultaneously, and supporting vehicle frame (6) to be level attitude by collet side arm (1) and spacer frame (9), strut bar (10) and placing that this car body and handlebar (4) are formed one and pushed away the thing dolly easily.This car body also can be landed simultaneously by wheel (11) and (13) three of poles, makes whole dolly become erectility, and this state can play urgent support brake action when stair climbing.
This gaholder is climbed the vehicle frame of building Labour-saving car and the power arm that is combined as lever of handlebar; Weight such as gaholder are placed on collet side arm (1) and the collet after-frame (3), its center-of-gravity position is the weight arm of lever to the distance of fulcrum wheel, the ratio of power arm and weight arm is about 6:1, when climbing going upstairs, respectively with wheel (11), or support wheel (8) is balance pivot, according to lever principle, and first pull-up handlebar (4), mention support wheel (8), before pulling a cart (4) again, make wheel (11) support the stair forward position, is fulcrum with support wheel (8) again, with the vehicle frame is that power arm is depressed, to lift wheel (11), when its raising height is high above the stair level, pull a cart before taking advantage of a situation (4), make wheel (11) climb up high one-level stair plane, then be fulcrum with wheel (11) again, the vehicle frame power arm lifted, and draw before taking advantage of a situation, make support wheel (8) climb up plane, higher one-level building, so going round and beginning again to bear a heavy burden steps on the building.Wheel (11) is 24Cm with support wheel (8) spacing, generally can keep lifting of support wheel (8) to bring into play with the function of going upstairs, as inadequate slightly, because of support wheel (8) installs in strut bar (10) lower end, strut bar (10) upper end is by the relevant position of bolted splice at vehicle frame.The spacer slideway of spacer frame (9) lower end clamps strut bar (10), and makes strut bar (10) that certain move place be arranged, and the jam of reason strut bar (10) not can not enter high one-level stair and influence support wheel (8).As slightly mishap being arranged, lighting and same stair plane of wheel (11) and pole (13) causes dolly to be the quasi-stable erectility in climbing the building process, and unlikely turning down.Handlebar crossbeam middle device has the auxilliary depression bar (5) that is 50 ° of angles with the handlebar plane, so that unlikely the bending over of operator can be operated.
Claims (3)
1, a kind of gaholder is climbed the building Labour-saving car, form by wheel, vehicle frame, handlebar, carriage etc., it is characterized in that strut bar (10) is under the tension of extension spring (7), be positioned at the apical position of the spacer slideway of spacer frame (9), this moment, the support wheel (8) of strut bar (10) lower end was in same plane with wheel (11), when vehicle frame erects, wheel (11) also places another plane with (13) three of poles, handlebar (4) adopts the grafting form of living, the active auxilliary depression bar (5) that is the acute angle angle with the handlebar plane that is plugged with of handlebar crossbeam midway location with vehicle frame (6).
2, gaholder as claimed in claim 1 is climbed the building Labour-saving car, it is characterized in that: spacer frame (9) upper end is the acute angle weldering extremely on the relevant position of vehicle frame (6), and its lower end has the spacer slideway.
