Description

Technical Field

[0001] The utility model relates to the technical field of stairs, in particular to a foldable indoor staircase. Background Art

[0002] Stairs are widely used in our daily life. Their function is to allow people to go up and down two platforms at different heights, especially in places with small spaces such as homes, shops, warehouses, fire escapes and elevator inspection shafts. Due to the large population in cities and high housing prices, many people choose to buy small houses, making the room area too small. However, most stairs cannot be folded and will take up a large space, which greatly affects the use of the space around the stairs.

[0003] Technicians in this industry have found that when using stairs in small spaces such as homes and shops, it is necessary to find a suitable location to place them to prevent the stairs from accidentally shifting during use, thereby causing harm to users and affecting the efficiency of stair use. For this reason, we propose a foldable indoor staircase. Utility Model Content

The utility model provides a foldable indoor staircase.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] The top end of the lifting plug in the lifting plug has a lock on the left side of the lifting plug, and the lock is fixed with a lock on the left side of the lifting plug, and the lock is fixed with a lock on the right side of the lifting plug.

[0007] Furthermore, two installation grooves are provided at the middle bottom end of the card slot, and the suction cup is movably installed in the installation grooves.

[0008] Furthermore, the upper end of the movable block is configured to be in an arc shape, and the diameter of the arc is consistent with the length of the groove.

[0009] Furthermore, the external thread formed on the circumferential surface of the screw rod is consistent in size with the internal thread formed inside the support rod.

[0010] Furthermore, the fixing ring is made of rubber, and the opening at the right end of the fixing ring is slightly smaller than the diameter of the support rod.

[0011] Furthermore, a layer of rubber pad is provided at the bottom of the anti-slip plate.

[0012] Furthermore, the length of the mounting groove is slightly larger than the bottom diameter of the suction cup.

[0013] The beneficial effects of the utility model are as follows:

[0014] 1. When the utility model is in use, the telescopic ladder body is first moved to the position where it needs to be used, and then the telescopic ladder body is extended to a certain height, and then the support rod is pulled out from the fixing ring, and then the screw rod and the support rod are rotated to make the support block at the bottom of the support rod contact with the ground, so that the support rod supports the telescopic ladder body, and then the rotating rod in the slots provided on both sides of the anti-slip plate is pulled outward to form a larger angle between the rotating rod and the anti-slip plate, and then the suction cup at the bottom of the support column at the front end of the rotating rod is made to contact with the ground to increase the pressure bearing area between the anti-slip plate and the ground, so that the telescopic ladder body is more stable, and in places where it is inconvenient for the user to support the telescopic ladder body, the support rod and the telescopic ladder body cooperate with each other, so that the user can use the telescopic ladder body more conveniently.

[0015] 2. When the utility model is in use, two installation grooves are provided at the middle bottom end of the card slot, and the length of the installation groove is slightly larger than the bottom diameter of the suction cup.
