Specific embodiment
It is a kind of can as the desk that ladder uses embodiment 1 as shown in Fig. 1 ~ 4：Including tall and erect seat 1 and tall and erect panel, tall and erect face
Plate includes the first desktop 2, the second desktop 4 and the 3rd desktop 6 of front and rear arrangement, and the first desktop 2 is flexible by first
Guiding movement is assemblied on table seat 1 leg 17 along the vertical direction, and the second desktop 4 is oriented to along the vertical direction by the second Retractive leg 18
Movement is assemblied on table seat, and by the 3rd Retractive leg 19, guiding movement is assemblied in the table seat to the 3rd desktop 6 along the vertical direction
On.The rear side of second desktop 4 is provided with second the first positioning step of desktop 11 of recess upward, before the second desktop 4
Side is provided with recess the second positioning step of the second desktop 25 directed downwardly.3rd desktop, 6 front side is provided with and the second desktop
3rd desktop positioning step 5 of the first positioning step adaptation support cooperation, 2 rear side of the first desktop are provided with and the second desktop
The second positioning step of plate adaptation support cooperation the first desktop positioning step 3, the recess of the first desktop positioning step upward,
The recess of 3rd desktop positioning step is downward.First Retractive leg in the present invention, the second flexible de-, the 3rd Retractive leg and table seat it
Between be both provided with for locking the Retractive leg fixed structure of corresponding Retractive leg after corresponding desktop Board position adjustment, first is flexible
Leg, the second Retractive leg and the 3rd Retractive leg are single leg structure.
In the present embodiment, Retractive leg fixed structure include that axis extends in left-right direction for holding out against corresponding Retractive leg
Top fastening screw 7,7 spinning of Top fastening screw is on table seat.Desk further includes lower end and the second Retractive leg is hinged and connected first is connected
Bar 8, the one end of head rod away from hinged end are provided with the spring catch that axis extends in left-right direction, and spring catch includes positioning
Pin 12 and the tension spring 13 being arranged between shop bolt and head rod are provided on the second Retractive leg to connect with first
Second Retractive leg location hole of the spring of the spring catch location fit on extension bar, head rod 8 when not in use, spring finger setting
It is plugged in the second Retractive leg location hole of the spring, head rod 8, which is located in, to be vertically arranged, and is provided on the 3rd Retractive leg 19
The 3rd Retractive leg spring catch location hole 9 being used for spring finger setting inserting that one row are distributed along the vertical direction.It is flexible second
The second connecting rod 10 is also hinged on leg, the second connecting rod 10 is identical with the structure of head rod, is used for and the first Retractive leg
On the first Retractive leg spring catch location hole be connected, head rod, the second connecting rod are in the opposite sides of the second Retractive leg,
Table seat includes being used to implement the guide ring 16 vertically extending with the axis of the second Retractive leg guiding movement cooperation, guide ring
Notch 14 is avoided with vertically extending first for avoiding the head rod and for avoiding the second connecting rod
Vertically extending second avoids notch.As desk in use, head rod, the second connecting rod are all connected to
On two Retractive legs, as shown in Fig. 2, the first desktop rises to certain altitude, the second desktop and the 3rd desktop are just located in
Respective heights hold out against fixation to each Retractive leg by Top fastening screw, the adjustment of height of table top are achieved that, due to as desk
In use, the supporting power of desktop is little, therefore the fixation to desktop can be realized by Top fastening screw；It is used as stair
When, the height of each Retractive leg is adjusted, the spring finger setting of head rod is plugged on the 3rd Retractive leg the corresponding 3rd stretches
In contracting leg spring catch location hole, the spring finger setting in the second connecting rod is plugged on the first Retractive leg corresponding first and is stretched
In leg spring catch location hole, the 3rd Retractive leg and the second Retractive leg are connected into an overall structure by head rod, and second connects
First Retractive leg and the second Retractive leg are connected into an overall structure by extension bar, when human body is stepped down on the first desktop, are passed through
The power transmission of head rod and the second connecting rod also carries the weight of human body between the second Retractive leg, the 3rd Retractive leg and table seat
Amount, when human body is stepped down on the second desktop, passes through the power transmission of head rod and the second connecting rod, the first Retractive leg, the 3rd
Also carry the weight of human body between Retractive leg and table seat, therefore each Retractive leg can make single leg structure, be conducive to make whole
A desk is more compact, while each Retractive leg joint action, it is ensured that the safety in utilization of stair.
In other embodiments of the invention：Retractive leg fixed structure can also be bolt fastening structure either pipe clamp.
It is a kind of can as the desk that ladder uses embodiment 2 it is as shown in Figure 5：Embodiment 2 is different from embodiment 1
It is that head rod 8, the second connecting rod 10 are length-adjustable telescopic advance lever, telescopic advance lever includes two sections of interval settings
The body of rod 81,83 and thread bush 82, two sections of thread bush 82 are equipped with oppositely oriented connection screw thread, the abutting end point of two sections of bodies of rod
It is not connected with being correspondingly connected with screw thread, by rotating thread bush, the length of telescopic advance lever can be adjusted, so as to spring catch
It is inserted into the spring catch location hole specified, on the one hand can so reduce the requirement to desk installation accuracy, it is in addition even more important
, head rod, the angle of inclination of the second connecting rod can be adjusted, because, the inclination of head rod, the second connecting rod
Angle is bigger（Closer to vertical state）, the active force that two neighboring Retractive leg is undertaken is average, that is to say, that first connects
Extension bar, the angle of inclination of the second connecting rod are bigger, and entire stair can carry more heavy weight people, and the crowd of different weight can
To select to use respectively.
