The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail.
Fig. 1 is the overall assembly structure figure of the Portable Automatic extension ladder of the utility model, Fig. 2 is the I portion partial enlarged drawing among Fig. 1, in conjunction with Fig. 1 and Fig. 2, a kind of Portable Automatic extension ladder of the utility model, comprise by some circular cleat stanchion nodal axisns forming left cleat stanchion 10, right cleat stanchion 11 that the two ends 20,21 of each grade ladder shelves 2 are connected to by connector 30,31 on the left cleat stanchion joint 10, right cleat stanchion joint 11 of corresponding every joint (shown in Fig. 3) to suit; The central axis of above-mentioned all cleat stanchion joints is on same straight line; And the center line of all above-mentioned ladder shelves is on same straight line (shown in Fig. 4).
Each cleat stanchion joint top is provided with a locating hole 13, the middle and lower part is provided with a locating hole 14 (Fig. 2 illustrates), distance after the distance that is decided to be hole 13 and locating hole 14 equals to trail between the adjacent two ladder shelves, best span when just the user climbs, this distance can specifically be set according to different use occasions and use crowd.
In the two ends 20,21 of ladder shelves 2 identical locking mechanism 4 is installed respectively, locking mechanism comprises a straight pin 41, one end of straight pin 41 props up spring 42, the other end of straight pin 41 dislocation pin is gone in the locating hole in the cleat stanchions joint of the adjacent suit of two joints, and promptly straight pin 41 sell simultaneously and gone into cleat stanchion and save the locating hole 13 on 11 tops and be positioned at the locating hole 14 that its inner cleat stanchion saves the middle and lower part.
Each locking mechanism cooperates respectively reply button 43 is installed; Described reply button is the spanner of controlled rounding pin 41 to the motion of spring 42 elastic force rightabouts.
Has a groove 44 between the two ends of straight pin 41; Described spanner is horizontal positioned " V " shape, and 45 ends, one side of " V " shape have the arc protuberance 46 that sticks in the straight pin groove 44, and the another side of " V " shape stretches out outside the ladder shelves 2, forms press section 47; The summit of " V " shape spanner is fixed on the ladder shelves by bearing pin 48, and forms the rotation center point.The protuberance frictional dissipation in groove 44 has for a long time been avoided in the arc design of protuberance 46.
The bottom of every joint cleat stanchion joint is equipped with a cushion pad 6, and the cleat stanchion joint that the design of cushion pad reduces upper level falls into the vibrations that next stage cleat stanchion joint produces, and effectively increases the application life of extension ladder.
More than design can realize goal of the invention of the present utility model substantially, during use, draw one-level ladder shelves 2 arbitrarily, when arriving the precalculated position, in the locating hole that the adjacent cleat stanchion of insertion of dislocation saved under straight pin 41 promptly can promote at the elastic force of spring 42, thereby realize fixing.So the utility model can stretch the length of requirement according to actual mode of occupation arbitrarily.During contraction, the reply button 43 at ladder grade 2 two ends of next stage is pressed after only needing will stretch simultaneously, owing to the central axis of all cleat stanchions joint on same the straight line and center line reasons on same straight line of all ladder shelves, the ladder shelves of upper level will drop on the plane of next stage ladder shelves, the reply button 43 of upper level ladder shelves will be pressed on the next stage ladder shelves, thereby make the straight pin 41 in the upper level ladder shelves break away from locating hole, realized the contraction of upper level.By that analogy, only need the reply button 43 of the minimum one-level ladder of control shelves as can be known, can realize whole contractions of whole ladder.
On the basis of the foregoing description, further improve and be, reply button mechanism in the one-level ladder shelves of extension ladder lowermost end comprises a connecting strand 5, the two ends of connecting strand are connected on the straight pin 41 on both sides, the centre of connecting strand is wrapped on the axis of rotation 51, and axis of rotation 51 stretches out ladder shelves 2 external fixation on a swing handle 52.This type of structure Design makes that the contraction of extension ladder is convenient, because only need rotate swing handle 52, and 51 rotations of driven rotary axle, thereby be intertwined and connected rope 5, make connecting strand 5 length shorten, the straight pin 41 that drives both sides moves to the centre, loses positioning action thereby break away from locating hole.Since then, promptly can catch up with and state identical operating principle and make that the above whole ladder shelves of ladder shelves fall automatically since then.Fig. 5 has embodied the stereochemical structure after the utility model contraction.
As shown in Figure 5, be provided with a fixed band 7 on the one-level ladder shelves 2 of lowermost end, fixed band 7 one ends are fixed on the ladder shelves 2, and the other end has a snap close 71.After whole ladder shrinks, fixed band 7 is walked around all ladder shelves, and utilize snap close 71 to fasten, prevent that with this utility model extension ladder the relatively moving of non-working condition descending stair shelves, is easy to carry more.
The utility model cleat stanchion joint also can adopt the design of rectangle, and the material of cleat stanchion joint can the aluminium alloy or glass fiber reinforced plastic, the fine material of carbon.
As well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection domain that the utility model limited, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
