[0061] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0062] Embodiment 1:

[0063] See also Figure 1-Figure 4 A foldable telescopic stool ladder comprises a device body 1, two symmetrically arranged sliding components 3 are installed inside the device body 1, two symmetrically arranged stabilizing components 2 are installed on the inner wall of the device body 1, and two climbing components 4 in a circumferential array are installed on the inner wall of the device body 1. The two stabilizing components 2 respectively include:

[0064] A support plate 21, which is fixedly mounted on the inner wall of the device body 1;

[0065] Two symmetrically arranged support plates 24 are fixedly mounted on the inner wall of the device body 1;

[0066] A second rotating plate 25, which is rotatably connected to one side of a second supporting plate 24;

[0067] A rotating rod 23, which is rotatably connected to one side of a rotating plate 25;

[0068] A second rotating rod 27, which is rotatably connected to one side of another second supporting plate 24;

[0069] The third rotating plate 26 is rotatably connected to one side of the second rotating rod 27 and is rotatably connected to the second rotating plate 25;

[0070] The rotating plate 1 22 has one side rotatably connected to the rotating rod 27 , the other side rotatably connected to the rotating rod 1 23 , and one end rotatably connected to the supporting plate 1 21 .

[0071] The specific implementation is that the rotating rod 1 23 and the rotating rod 27 are both rotatably connected to the rotating plate 1 22 through fixing bolts, there is a fixing bolt at the connection between the rotating plate 1 22 and the support plate 1 21, and the rotating plate 3 26 and the rotating plate 2 25 are connected by a fixing bolt (the fixing bolt is not marked in the figure).

[0072] The device body 1 comprises:

[0073] Four support members 18, two of which are grouped together and fixedly connected to one side of the second support plate 24;

[0074] Four connecting frames 17, which are rotatably sleeved on the top of the supporting member 18 respectively;

[0075] Four bolts 16, which respectively penetrate the connection frame 17 and the support member 18, and are rotatably connected to the inner walls of the two;

[0076] Baffle 2 15, which is fixedly mounted on the top of the supporting members 18 in groups of two;

[0077] A second bracket 14, which is fixedly mounted on one side of the second baffle 15;

[0078] Baffle 11, which is fixedly mounted on the top of another pair of support members 18;

[0079] A bracket 12, which is fixedly mounted on one side of the baffle 11;

[0080] The fixing member 13 is slidably connected between the bracket 12 and the bracket 2 14 .

[0081] The specific implementation is that the second bracket 14 and the first bracket 12 are slidably connected. When the device is in a fully retracted state, the columns between the second bracket 14 and the first bracket 12 abut against each other.

[0082] The four support members 18 respectively include:

[0083] Stool legs 181, which are rotatably connected to the inner wall of the connecting frame 17;

[0084] An extension member 183 slidably connected to the inner wall of the stool leg 181;

[0085] The limiting member 182 is slidably connected to the stool leg 181 and the inner wall of the elongated member 183 , and is used to fix the elongated member 183 .

[0086] The specific implementation is that one side of the extension piece 183 has a plurality of holes penetrating through it in a linear array for adjusting the height of the entire device. The lengths of the stool legs 181 and the extension piece 183 can be produced in different specifications according to requirements.

[0087] The fixing member 13 includes:

[0088] A fixed frame 131, which is slidably connected to the bracket 1 12 and the bracket 2 14 respectively;

[0089] Two symmetrically arranged fixing plates 132 are fixedly connected to one end of the first bracket 12 and one end of the second bracket 14 respectively.

[0090] In a specific implementation, the fixing frame 131 is slidably connected to a column in the middle of the bracket 12 , and is also slidably connected to a column in the middle of the bracket 2 14 .

[0091] The two sliding components 3 respectively include:

[0092] A slide plate 37, which is slidably connected to the bottom of the bracket 12;

[0093] Two symmetrically arranged fixing blocks 31, which are respectively fixedly connected to one side of the stool leg 181;

[0094] Two symmetrically arranged rotating plates 33 are respectively rotatably connected to one side of the fixed block 31;

[0095] Two symmetrically arranged fixing plugs 32, which respectively penetrate the rotating plate 1 33, and are used to connect the rotating plate 1 33 and the fixing block 1 31;

[0096] Two symmetrically arranged rotating plates 2 35, one end of which is rotatably connected to one side of the rotating plate 1 33;

[0097] Two symmetrically arranged rotating shafts 36, which are rotatably connected to the inner walls of the rotating plate 1 33 and the rotating plate 2 35;

[0098] Two symmetrically arranged reinforcement blocks 34, which are slidably connected to the rotating plate 1 33 and the rotating plate 2 35 respectively;

[0099] Two symmetrically arranged second fixing blocks 38 are respectively fixedly mounted on one side of the sliding plate 37 and are rotatably connected to the second rotating plate 35 .

[0100] The specific implementation method is that when the extension line of the length direction of the rotating plate 1 33 coincides with the extension line of the length direction of the rotating plate 2 35, the reinforcement block 34 is slid to the connection between the two to fix the two. The connection parts of the sliding assembly 3 that need to be connected are all fixed by fixing bolts (not marked in the figure).

[0101] The climbing components 4 include:

[0102] A rotating column 41, which is rotatably connected to one side of the stool leg 181;

[0103] The climbing plate 42 is fixedly sleeved on the outer side of the rotating column 41 .

[0104] A specific implementation is that an anti-skid pad is installed on the top of the climbing board 42 to increase friction and prevent the staff from falling down due to too little friction when climbing, thereby causing harm to the staff.

[0105] Embodiment 2:

[0106] See also Figure 5 , a foldable telescopic stool ladder, the heightening component 5 comprises:

[0107] Four heightening posts 51 are slidably connected to the bottom of the elongated member 183 in a circular array;

[0108] Two symmetrically arranged second fixing members 52, which are slidably connected between the two heightening columns 51;

[0109] Two symmetrically arranged limit groups 53 are movably installed between the two heightening columns 51 .

[0110] The specific implementation is that the connection between the second fixing member 52 is through a fixing column (not marked in the figure), the second fixing member 52 is used to reinforce the heightening column 51, and the limit group 53 can be fixed and disassembled by bolts, which facilitates the disassembly and assembly of the heightening component 5 and is convenient to carry.

[0111] Working principle: When in use, the staff first rotates the supporting members 18 in pairs with the axis of the bolt 16 as the center to the maximum position. At this time, the rotating plate 1 22 rotates to the horizontal direction, and the rotating plate 2 25 rotates to the horizontal direction, which drives the rotating rod 1 23 to rotate, and the rotating plate 3 26 rotates to the horizontal direction, which drives the rotating rod 2 27 to rotate. At this time, the stabilizing components 2 all reach the maximum limit and complete the effect of supporting the whole. While pulling the supporting member 18, the sliding component 3 moves, and the rotating plate 1 33 rotates with the axis of the fixed plug 32 as the center, which drives the rotating plate 2 35 to rotate with the axis of the rotating shaft 36 as the center. When the projections of the same plane of the rotating plate 1 33 and the rotating plate 2 35 coincide, slide the reinforcement block 34 to the connection between the two to further fix the device as a whole;

[0112] When the length of the ladder stool needs to be adjusted, the baffle plate 11 and the baffle plate 2 15 are pulled respectively, and the baffle plate 11 drives the bracket 12 to slide along the length direction of the fixed frame 131, and the baffle plate 2 15 drives the bracket 2 14 to slide along the length direction of the fixed frame 131 until the required length is reached, and then the pulling is stopped. When the height needs to be adjusted, the limiter 182 is pulled out, and after the extension member 183 is pulled to reach the required height, the limiter 182 is inserted again;

[0113] After the above steps are completed, the staff bends the climbing board 42 to rotate it around the axis of the rotating column 41. When the climbing board 42 is in a horizontal position, the bend is stopped, and the staff can climb to the top of the device.

[0114] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
