Be described further below in conjunction with accompanying drawing and enforcement

By Fig. 1 stilt formula ladder schematic diagram as can be known, stilt formula ladder is made up of the identical terraced bar of left and right two root architectures.Figure A is left terraced bar (outward appearance) schematic diagram, and figure B is right terraced bar (section) schematic diagram.The ladder bar comprises supporter and lifting body two large divisions, support bar 1 both sides of supporter are processed with gathering sill 11 respectively and are in several holes on the straight line as mortise 23, upper and lower end is processed with outer Luo line, inner thread in the circular hole outside the lower end in Luo line and the steadying plate 2 docks assembling, and by female 7 lockings of locking Luo.The main body of lifting body is to be sleeved on the outer fall way 5 of support bar 1, is equipped with foot pedal 6 and cingulum 8 and 9 on the body one side outer wall, and the gib block 10 that is provided with on the inner diameter wall drops on loose fit in the gathering sill 11 that support bar 1 opened.Under the effect of external force, the track that fall way 5 can stably fit in according to gib block 10 and gathering sill 11 is made rectilinear motion up and down on support bar 1, not only guaranteed on the fall way 5 the mortise of offering 12 can overlap with any one mortise in some mortises of being offered on the support bar 1, guaranteed that also fall way 5 can not rotate or twist on support bar 1.One end of shell fragment 13 fixedly is assemblied on fall way 5 outer walls on mortise 12 tops, and the other end is equipped with removable pin 14 and aims at mortises 12, under the effect of external force, and along with being pressed and being upspring of shell fragment 13, removable pin 14 mortise 12 of can freely coming in and going out.The operating grip 15 of lift control system links together with connecting rod 16, and connecting rod 16 is set with spring 19 after passing perforation on operating grip location-plate 17 and the resistance spring plank 18, then with box body in the control box 21 of roller 20 is housed horizontal box wall be fixed together.Vertical box wall of control box 21 is assemblied in the little gathering sill 22 that is had on the tube wall of mortise 12 both sides on the fall way 5, and mortise 12, shell fragment 13, removable pin 14 are covered in the box.To scheme A, figure B two terraced bars are put together, and 6 one of foot pedals are put to the right for one left relatively, just form a secondary stilt formula ladder.

Referring to Fig. 1, Fig. 2, Fig. 1 is a stilt formula ladder schematic diagram.Fig. 2 makes view for stilt formula ladder work, the course of work of these stilt formula ladder is, from the figure B of Fig. 1, can see, the overlapping of mortise 23 that removable pin 14 drops on one of the some holes of offering on the mortise 12 offered on the fall way 5 and the support bar 1 forms joinery and its construction in the hole, with fall way 5 be positioned at support bar 1 as on the figure height.The end user steps on bipod respectively on the foot pedal 6 on the two terraced bars about figure A, figure B, fastens cingulum 8 and 9, just can work on ladder.When needs are raised the height of oneself, figure A referring to Fig. 2, the end user can be pulled upwardly operating grip 15, by connecting rod 16, drive control box 21 and move upward along little gathering sill 22, be stuck in control box 21 and be compressed with spring 19 in the middle of the resistance spring plank 18, at this moment roller 20 rises with control box 21 and leaves shell fragment 13, the shell fragment 13 that loses pressure produces elastic force shank 14 is extracted from mortise 23, and fall way 5 loses positioning control on support bar 1.End user one carries pin, cingulum 8 and 9 drives fall way 5 and rises with pin, when the mortise on the fall way 5 when mortise 24 on the support bar 1 overlaps fully, figure B referring to Fig. 2, put down operating grip 15, compressed spring 19 is out of hand, produce elastic force, spring 19 upper ends are hindered spring plank 18 restrictions, can't upwards uphold, only the control box 21 that loose fit can be installed in the little gathering sill 22 pushes away downwards, and the roller 20 on the box body that is fixed on control box 21 is moved downward in the lump, when roller 20 drops to shell fragment 13 and removable pin 14, shell fragment 13 and removable pin 14 are pressed to fall way 5.Removable pin 14 is pressed in the mortise 24 on the support bar 1 by the mortise on the fall way 5 12, forms joinery and its construction once more, makes fall way 5 be repositioned at the height at mortise 24 places on the support bar 1.The lifting body that uses the same method another root ladder bar is raised to same height, and the people just can be in this new height work.If also fail to reach Desired Height, can operate equally once more or repeatedly, until achieving the goal.If the end user need reduce height or get back to ground, the method for operating of hand is equally carried out with rising, and foot action changes into foot pedal 6 can be descended to pressing down.In process of rising or falling, if the mortise on lifting body fails to have put down when mortise on the supporter overlaps operating grip, the elastic force effect of opening along with shell fragment 13, removable pin 14 may be crushed on the atresia tube wall of support bar, it is very little to be designed to the frictional force that the shank end of round end is pressed on the support bar tube wall, as long as pin is carried or pressed down on again, falls into " funnel " shape mortise of enlarging easily, again form joinery and its construction, fall way is fixed on the supporter.

Fig. 3 is a rectangle stabilizer schematic diagram.Figure A is a lateral view, figure B is a upward view, steadying plate 2 centers have one vertical and penetrate the circular hole 25 of steadying plate, be manufactured with the Luo line on the hole wall, four jiaos of the steadying plate bottom surface by edge, be provided with from inside to outside by cornerwise extended line direction and stretch out, and tilt earthward and also the gradient unanimity form the duplex stability pin by Convenient table 3 and adjustable pin 4 and anti-sliding sleeve 26, Convenient table 3, can not be changed with the angle of steadying plate at 2 ends of steadying plate by solid welding.Adjustable pin 4 is clipped in the middle of the Convenient table 3, with the Luo silk they is assembled together, and can adjust the angle angle on it and ground as required.The number of stablizing pin is according to actual adjustment, and stabilizer becomes to have steadying plate to have the stable pin formula except that designing and producing, and it is flat to be designed to not have stable pin, uses to adapt to soft terrain.

The support bar 1 of seeing Fig. 1, Fig. 3 stilt formula ladder vertically is assemblied on the bigger steadying plate 2 of the area of stabilizer, and what being provided with of steadying plate and stable pin enlarged support bar for twice puts forth effort area and scope.Every pair of stable pin of stabilizer and steadying plate constitute arch, help the propagation and the dispersion of power.Stable pin had not only all been formed a plurality of angles with steadying plate but also with ground, formed a plurality of gusseted power and stability force.There is certain space between per two stable pin and the steadying plate, can avoids the object that the uneven point on ground and fragment of brick etc. influence ladder stabilizer effectively.Being provided with of stabilizer guaranteed ladder stabilizer.Among Fig. 4, figure A is stilt formula ladder working state figure on the J of level ground, because the length of the stable pin that steadying plate 2 bottoms are provided with and it are consistent with the angle of slope of ground formation, steadying plate 2 is parallel to ground J, the support bar 1 that is vertically mounted on the steadying plate 2 also must fall in level ground J, and the gravity F that has guaranteed support bar 1 and people is perpendicular to ground.Figure B is that stilt formula ladder is having gradient ground handling state diagram, and gradient ground J is being arranged ¹When last use stilt formula is terraced, keep the stable pin length and the gradient of steadying plate 2 bottoms one end constant.Adjustable pin 4 and non-slipping block angle on the stable pin of the adjustment other end so just can make steadying plate 2 be parallel to the horizon J on ground, and terraced bar 1 and end user's gravity F is kept perpendicular to ground.Adjustment through to the sufficient adjustable pin of stilt formula ladder has improved compliance and the stability of stilt formula ladder to multiple ground effectively.

In Fig. 5 support bar schematic diagram, figure A is the main support rod sectional drawing, and the two ends up and down of main support rod 1 are processed with outer Luo

line

27 and 28 respectively, and the inner thread in steadying plate 2 circular holes that open at the center 25 of outer Luo line 27 and Fig. 3 stabilizer is used; The mortise that vertically is processed with several mortises 23 on the body of rod wall of support bar 1 one sides penetrates tube wall, porose line be on same the straight line, this locating hole that linearly is provided with also can be designed to the tooth bar form.Vertically be processed with a gathering sill 11 on the opposite side rod tube wall.Figure B is the extension bar sectional drawing, and making and the main support rod of extension bar are roughly the same, and difference is that the extension bar lower end need not process outer Luo line and changes at the rod tube inwall and process inner thread 29.When the stilt formula ladder insufficient height of forming with main support rod, figure B extension bar lower end inner thread 29 can be cooperated with the outer Luo line 28 of figure A main support rod upper end, be assembled into longer support bar, and increase the height of stilt formula ladder, a secondary stilt formula ladder is equipped with two main support rods and Duo Gen extension bar.

In Fig. 6 fall way schematic diagram, figure A, figure B are respectively fall way section and schematic appearance.Fall way 5 is provided with mortise 12 devices such as grade, and two parallel little gathering sills 22 are the set-point of control box and the control track when moving up and down.

Except that schematic design is as shown in Figure 1 made and is assembled the terraced bar member, Convenient table 3 can merge with adjustable pin 4 and be designed to monolithic and stablize pin, duplex stability pin or monolithic stablize bar that pin all can directly be assemblied in support bar 1 enough the no steadying plate of formation stable pin formula stabilizer is arranged; Gib block 10 and gathering sill 11 can exchange the position is set; After the scheme that designs and produces and rigging position change with upper member, basic identical before effect that is produced and effect and the change.

Stilt formula ladder has changed the structure and the working method of common ladder fully, common ladder be beyond one's reach technical characteristic and technical effect have been reached, product is easy to use, simple to operate, control flexibly, have good practicability, can replace conventional elevator and be applied to multiple industry ascend operation, also can be as toy and entertainment body-building equipment.
