Preferably, the bottom surface of base plate is provided with anti-slip tank, and base plate is provided with double wedge.Anti-slip tank can prevent hand steered stair from beating It is sliding；Double wedge is used to pressing close to when in use the fixtures such as corner prevents rollover.
Preferably, motion bar is hollow cube structure, and left and right sides wall is provided with first mounting hole, described two Individual first mounting hole is distributed with one heart, and some second mounting holes are equipped with front and rear two side.Through fastening spiral shell in first mounting hole Bolt makes motion bar be fixed with support feet, and the second mounting hole is matched with arrangement for adjusting height for adjusting motion bar highly, operation letter It is single, easy to adjust.
Preferably, fixed mount includes starting stave, the second riser, the 3rd riser and the 4th riser, the second riser both sides point Starting stave and the 3rd riser are not fixed with, groove is formed between starting stave, the second riser and the 3rd riser, be provided with groove Groove is divided into motion bar fixed area and mounting groove, the starting stave of motion bar fixed area and the 3rd by the 4th riser, the 4th riser Arrangement for adjusting height is equipped with riser, the 3rd mounting hole is provided with the first montant and the 3rd riser in mounting groove.Activity Bar fixed area is used to fix motion bar, and the arrangement for adjusting height in motion bar fixed area is used to adjust motion bar highly；Mounting groove The 3rd interior mounting hole is used to fix hand steered stair.
Preferably, arrangement for adjusting height includes Nut column, and clamp button of the spring is housed on Nut column.Closing clamp button of the spring makes fixation Frame is fixedly connected with motion bar；Opening clamp button of the spring makes fixed mount and motion bar be slidably connected, so as to adjust sliding bar highly.
Preferably, clamp button of the spring size matches with the second mounting hole size.Clamp button of the spring is facilitated to insert the second mounting hole, Coordinate more firm when fixing fixed mount and motion bar.
Compared with prior art, the utility model has the advantages that：In the mounting groove of the pin insertion fixed mount of stair, and pass through Bolt makes the pin of stair be fixedly connected with fixed mount, and fixed mount is nested with motion bar, and height is provided between fixed mount and motion bar Degree adjusting means, the height of motion bar can be changed by arrangement for adjusting height, so that it is long to adjust hand steered stair or so foot of stairs The difference of degree, allows stair to adapt to the ground of different height；Support feet includes base plate, and base plate is provided with two pieces of sides being parallel to each other Plate, is provided with S-shaped groove on side plate, the fastening bolt for fixing motion bar is provided between two S-shaped grooves, is fastened by adjusting Position of the bolt in S-shaped groove enables hand steered stair make on ground inclining or to bend etc. so as to change the direction of support feet With.It is convenient that overall structure is carried, easy to operate, lightweight.

Specific embodiment
Embodiment of the present utility model is further illustrated below in conjunction with the accompanying drawings：
As shown in Fig. 1, Fig. 5 and Fig. 6, a kind of telescopic stair support, including fixed mount 3, motion bar 2 and support feet 1, Gu Determine frame to be nested with motion bar, motion bar bottom is provided with support feet.
As shown in figure 3, fixed mount includes starting stave 31, the second riser 32, the 3rd riser 33 and the 4th riser 34, second Riser both sides are respectively fixed with starting stave and the 3rd riser, and groove is formed between starting stave, the second riser and the 3rd riser, The 4th riser is provided with groove, groove is divided into motion bar fixed area and mounting groove 36 by the 4th riser, in motion bar fixed area Arrangement for adjusting height is equipped with starting stave and the 3rd riser, arrangement for adjusting height includes Nut column 35, is equipped with Nut column Clamp button of the spring, is provided with the 3rd mounting hole 37 on the first montant and the 3rd riser in mounting groove, the 3rd mounting hole is used for this Utility model is fixed on hand steered stair.
As shown in Fig. 2 support feet includes base plate 12, base plate is provided with two blocks of side plates 11 being parallel to each other, is opened on side plate There is S-shaped groove 111, the fastening bolt for fixing motion bar is provided between two S-shaped grooves, the bottom surface of base plate is provided with anti-slip tank 121, base plate rear end is provided with double wedge 122, and anti-slip tank can prevent hand steered stair from skidding, and double wedge is used to press close to corner when in use Rollover is prevented Deng fixture.
As shown in figure 4, motion bar is hollow cube structure, left and right sides wall bottom is provided with first mounting hole 22, two coaxial lines of the first mounting hole 22 are equipped with some second mounting holes 21 on front and rear two side, the second mounting hole size with Clamp button of the spring size matches.
When the utility model is not used, fixed mount, motion bar and support feet can be broken and be placed in tool box, carrying side Just.When it is desired to be used, fixed mount is first taken out, the one side that fixed mount is provided with mounting groove is stuck in the foot of ladder bottom of hand steered stair, It is set to be fixed on hand steered stair through the 3rd mounting hole with bolt；Then the clamp button of the spring on fixed mount is opened, motion bar Motion bar fixed area is penetrated, turning off clamp button of the spring makes clamp button of the spring insert the second mounting hole, fixes motion bar；Finally open Fastening bolt, is passed through the first mounting hole by the fastening bolt in support feet, support feet is fixed with motion bar.After installation, Motion bar is adjusted highly by clamp button of the spring, the position adjustments support feet angle by fastening bolt in S-shaped groove makes hand steered Stair meet the gradient of field ground, flatness etc..The utility model simple structure, easy to carry, unfavorable terrain enters out of doors During row ascending stair, operating personnel can at any time adjust ladder or so foot of stairs length.
Specific embodiment of the utility model is the foregoing is only, but technical characteristic of the present utility model is not limited to This, any those skilled in the art in field of the present utility model, all cover new in this practicality by the change or modification made Among the scope of the claims of type.
