Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0039] Referring to Figure 1 and Figure 2 , the utility model provides an embodiment: a house stairwell stable type guardrail, including hollow base 1 and hollow rod 12, two hollow base 1's top all are fixedly connected with hollow column 3, two hollow column 3's adjacent side all are set with open slot 4, right side hollow column 3's front end middle and lower part rotationally connected with rotating rod 5, rotating rod 5's rear end penetrates corresponding hollow column 3 and is fixedly connected with driving bevel gear 6, right side hollow column 3's inside bottom rotationally connected with lead screw 7, lead screw 7's outside middle and lower part is fixedly connected with driven bevel gear 8, and driven bevel gear 8 is engagedly connected with driving bevel gear 6, and lead screw 7's outside is screw-connected with first movable column 9, and left side hollow column 3's inside is provided with second movable column 10, and two first movable column 9 and second movable column 10's adjacent side all are equidistantly fixedly connected with a plurality of guard rods 11, and hollow base 1's inside is provided with reinforcing mechanism 2, and a plurality of guard rods 11's one end respectively penetrates corresponding open slot 4, and a plurality of guard rods 11's adjacent end respectively with corresponding hollow rod 12 inside slidingly connected, and first movable column 9 and second movable column 10's size respectively with corresponding hollow column 3 inside size size match;

[0040] Specifically, rotating the rotating rod 5 can drive the driving bevel gear 6 to rotate, and at the same time, since the driven bevel gear 8 is tightly engaged with the driving bevel gear 6, it will also rotate, and this consecutive action will further push the first movable column 9 outside the lead screw 7 to move vertically upward along the sliding groove 14. In this process, the second movable column 10 will move with the first movable column 9. Such a design allows the height of the guardrail to be flexibly adjusted according to the height of the stairs, and by moving the hollow column 3 to both sides, the position of the guard rod 11 inside the hollow rod 12 can also be adjusted accordingly, so that it can adapt to stairs of different length specifications, and such an adjustment mechanism ensures that the guardrail can meet the needs of different users.

[0041] Referring to Figure 1 and Figure 3 The reinforcing mechanism 2 comprises first bolts 201 and a transmission belt 204, two first bolts 201 are respectively threadedly connected to the top right front end of the corresponding hollow base 1, the middle and lower parts of the first bolts 201 penetrate the hollow base 1, the inner sides of the bottoms of the two hollow bases 1 are threadedly connected with a plurality of second bolts 202, the outer sides of the first bolts 201 and the second bolts 202 are fixedly connected with pulleys 203, the pulleys 203 are drivingly connected through the transmission belt 204, and the middle and lower parts of the first bolts 201 and the second bolts 202 penetrate the corresponding hollow bases 1 and are threadedly connected with the pre-prepared mounting holes inside;

[0042] Specifically, rotating the first bolt 201 will rotate the pulley 203 on the outer side, and at the same time, through the connection of the transmission belt 204, the pulley 203 on the outer side of the second bolt 202 will also start to rotate, and this design allows the second bolt 202 to rotate following the movement of the first bolt 201. In this process, the first bolt 201 and the second bolt 202 will be pushed into the mounting holes pre-set on the stairs at the same time, and such a structure makes it very convenient to disassemble and fix the guardrail, greatly improving the practicality and operation efficiency of the device.
