The door lock 600 may have various known possible structures, preferably, as shown in fig. 2, the door lock 600 is a spring bolt, for example, the structure disclosed in the chinese patent with the publication number CN 211818795U; the door lock 600 may be designed according to the requirement, in the structure of the ladder 700, the door lock 600 may be disposed at the middle height of the door, at this time, the lock tongue of the door lock 600 moves horizontally, the locking hole is disposed on the rail 400, specifically, a locking member 800 matching with the lock tongue of the spring bolt is disposed on the inner side of the rail 400, and the hole or slot on the locking member 800 is a locking hole, and of course, a slot matching with the lock tongue may also be directly formed on the rail 400 as a locking hole; when no ladder 700 is present, the door lock 600 is located at the door and is close to the bottom of the door, at this time, the locking tongue of the door lock 600 may move horizontally, the locking hole is provided on the rail 400, the locking tongue of the door lock 600 may also move vertically, and the locking hole is provided on the work platform 300, so that it is convenient for a worker to operate the door lock 600 on the ground to open the door in a structure without the ladder 700.
As shown in fig. 2 and fig. 3, since the working platform 300 is raised and then has a risk of toppling, in order to improve safety, two sides of the base 100 in the length direction are respectively hinged with support rods 900, four hinge positions of the support rods 900 and the base 100 are close to four top corners of the base, the support rods 900 are provided with adjusting screws 01, the adjusting screws 01 are perpendicular to the working platform 300 and are in threaded connection with the outer ends of the support rods 900, the upper ends of the adjusting screws 01 are connected with an operating rod 02, and the operating rod 02 is perpendicular to the adjusting screws.
Preferably, the support bar 900 is a telescopic bar, which enables the support bar 900 to be longer in the case of a limited size of the base, thereby improving the supportability. The telescoping pole may employ known, viable mechanisms, and in one embodiment the support pole 900 is configured, for example, like a mop telescoping pole.
In another embodiment, as shown in fig. 4, the supporting rod 900 includes a first rod section 910 and a second rod section 920, where the first rod section 910 is inserted into the second rod section 920, and the spring plunger 03 is disposed at a portion of the first rod section 910 inserted into the second rod section 920, and a specific structure of the spring plunger 03 may be, for example, a structure disclosed in chinese patent with an issued publication number CN 212318613U; the axis of the telescopic column 031 of the spring plunger 03 is perpendicular to the axis of the first pole segment 910 and protrudes out of the surface of the first pole segment 910, a row of through holes 911 matched with the telescopic column are arranged on the support rod 900, and the structure is more convenient to adjust relative to the structure of the telescopic rod of the mop. When the second pole section needs to be adjusted, the telescopic column is pressed down to enable the telescopic column to withdraw from the through hole where the telescopic column is currently located, and the second pole section is pulled, so that the telescopic column is embedded into the needed through hole, the length of the supporting rod 900 can be adjusted, and the telescopic column can effectively adapt to the use requirements of different scenes.
In order to prevent the support bar 900 from being rotated to be opened during the movement of the base 100, a magnet (not shown) is provided at the side of the base 100, and the support bar 900 is made of a material that can be magnetically attracted, so that the support bar 900 can be magnetically attracted and fixed in a position close to the side of the base 100.
The utility model has various embodiments, and all technical schemes formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
