Abstract
The utility model discloses an effort-saving carriage for climbing-up stairs. A support frame [10] fixed with racks [7] is arranged on the lower side of a carriage body [1]; by utilizing the lever principle, a gear on the carriage body [1] is rotated by a cranker [4], making the carriage body risen to the next step along the racks [7]; a support frame is uplifted to reset by the spring tension. The utility model alternates and rises as such, achieving the goal of stable and labor saving transportation of the weight upstairs.
Description
The utility model relates to a kind of cart for travelling up or down stairs, particularly a kind of laborsaving cart for travelling up or down stairs.
The product or the technical scheme of now existing multiple cart for travelling up or down stairs, its common feature is to utilize manpower, stair activity also can use on the level land simultaneously more reposefully.But the action that most of cart for travelling up or down stairss just will be gone upstairs converts the vertical motion of pulsation-free oblique line to, (for example notification number is " the manually up/down steps car " of GG85203676) that the weight of vehicle body and load is still directly tried hard to recommend or drawn by the people do not have can the labour-saving device, is unsuitable for old personnel's use.Notification number be GG85200425's " load-carrying cart for travelling up or down stairs ", designed " chain wheel driving mechanism " as work-saving device, the labour-saving effect is arranged, but the end user need fall back upstairs, it is convenient inadequately to use.
The purpose of this utility model is that design is a kind of without external energy, again can be steadily, effortlessly carrying heavy goods upstairs, the also spendable home-use car on the level land simultaneously.
Principle of design of the present utility model is as follows: the support of establishing an energy and the relative up-and-down movement of vehicle body at body bottom section.Vehicle body and support alternately rise, and alternately support, and climb up to the one-level one-level stair.In the time of upstairs, support is supported on ground (first order step) earlier, makes vehicle body rise to the height of last layer (second stage) step and is supported on the step of the second stage.At this moment utilize spring tension that support is promoted and reset, also be supported on the step of the second stage, finish the action of climbing.The vehicle body that raises again repeats the above-mentioned action of climbing to third stage step, can climb up stair.Vehicle body is achieved in that in the lifting on the support gear that is contained on the vehicle body and the tooth bar that is fixed on the support intermesh, and by a crank arm revolving gear, gear can drive vehicle body and load rises along tooth bar.According to lever principle, as long as the length (arm of force) that makes crank can realize the labour-saving purpose greater than tooth radius (weighing arm).
Do further narration below in conjunction with drawings and Examples.
Fig. 1 is the right elevation of embodiment, and Fig. 2 is a block diagram.
Vehicle body (1) is made up of two main legs (12), transverse tube (13) and the storage plate (14) that is fixed on the transverse tube (13).Detachable folding frame (17) is housed around the storage plate (14).A wheel (6) respectively is equipped with in two main legs (12) bottom, and each fixes a geared sleeve (18) main leg (12) middle part.A big gear wheel (2) is housed in the right side gear cover (12).Below the storage plate (14), with transverse tube (13) pinion shaft (20) is housed abreast, a miniature gears (3) is respectively installed at the two ends of axle, two miniature gearss (3) are contained in interior work of geared sleeve (18) of both sides respectively and rotate synchronously, miniature gears on right side (3) and big gear wheel (2) engagement are installed a detent (15) in the edge of right side miniature gears (3) simultaneously.The oblique handlebar (21) of fixing in the left side of vehicle body (1).Right-hand member in Large Gear Shaft During (19) is equipped with a crank (4), and crank (4) can be done fan-shaped swing around Large Gear Shaft During (19), and amplitude of fluctuation is in 90 °.The length of crank (4) is identical with handlebar (21), and the ratio of while with the radius of big gear wheel (2) is 7:1.Edge's ratchet of installation (22) that crank (4) is gone up near big gear wheel (2) is equipped with control handgrip (5) at the free end of crank (4), and control handgrip (5) links to each other with ratchet (22), detent (15) by steel rope (11).The steel wire loop that only draws among the figure is also used (11) mark.
A support that is welded into by tubing (10) is arranged below storage plate (14), a pair of preceding support wheel (8) is equipped with in the place ahead of support (10), a pair of back support wheel (9) is equipped with in the below, the middle part is fixed with a pair of tooth bar (7), two toothed rack (7) stretch into respectively in the geared sleeve (18) of vehicle body (1) both sides, mesh with miniature gears (3).Respectively there is a long tension spring (16) vehicle body (1) both sides as retracing spring, and two ends are separately fixed on main leg (12) and the support (10).
When climbing the building, the back support wheel (9) on the support (10) is supported on the ground (first order step) simultaneously with wheel (6), and preceding support wheel (8) is supported on upper class (second stage) step.Press crank (4), drive big gear wheel (2) inhour by ratchet (22) and rotate, miniature gears (3) clockwise rotates, and drives vehicle body (1) and load upwards promotes along tooth bar (7).When the lower edge of wheel (6) rises to step plane, the second stage, car is slightly pushed away forward, wheel (6) drops on and bears full car weight amount on the step of the second stage.At this moment pinching control handgrip (5), discharge ratchet (22) and detent (15) by steel rope (11), support (10) (support wheel (8), (9) and tooth bar (7) before and after comprising) promptly promotes under the effect of reset tension spring (16) and resets, and finishes the action of climbing.This moment, preceding support wheel (8) can support to third stage step, and back support wheel (9) can be supported in second stage step.Press crank (4), wheel (6) is promoted to third stage step, begin the action of climbing for the second time.Move in circles with this, can climb up the floor of wanting.In climbing, storage plate (14) remains horizontality.When the end user pressed crank (4) with the right hand, left hand was helped handlebar (21), to keep the stability of car, was convenient to the right hand simultaneously again firmly.In the present embodiment, the ratio of crank (4) length and big gear wheel (2) radius is 7:1, so only need the power of full car (comprising load) total weight 1/7th, can press crank (4).
Go up to connect a flat steel bar at vehicle body (1), its free end is opened a hole, goes up fixing one with crank (4) and has strong market potential and be buckled together, can crank (4) is fixing, become right handlebar, and with left side handlebar (21) symmetry, be convenient to the level land and use.When using, the level land can also can become a four-wheeled only with two wheels (6) pulling by a pair of back support wheel (9) and wheel (6) load-bearing simultaneously.
Cart for travelling up or down stairs of the present utility model remains horizontality when going upstairs, bulk product such as carrying honeycomb briquette, vegetables and coal gas, grain are all very easy, also can load children or patient upstairs.Because utilize lever principle, reached the labour-saving purpose, for resident old in the high residential building provides a kind of new installation.
