The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, a first embodiment of the present invention provides an attached lifting scaffold, which includes a frame body 1 and a wall-attached device 2, wherein a guide device 3 is disposed on the wall-attached device 2.

Specifically, the middle part of support body 1 is equipped with backup pad 11, the lower surface of backup pad 11 is equipped with electric block 14, be equipped with chain 4 on the electric block 14, lie in on the support body 1 be equipped with cylindric transfer pole 12 under the

bracing piece

11, 3 fixed mounting in of guider attach the bottom of

wall device

2, 2 down of guider are equipped with sprocket 5, support body 1 is close to sprocket 5 is equipped with dead lever 13, dead lever 13 is located sprocket 5's below, chain 4 is followed the lower part of transfer pole 12 is walked around, and is passed through sprocket 5, again with dead lever 13 fixed connection.

The invention has the advantages that a plurality of chain wheels are not needed, and the chain directly bypasses the cylindrical transfer rod 12 and is connected with one chain wheel, thereby greatly improving the stability of the lifting structure.

In particular, the sprocket wheel 5 is screwed to the guide 3 by means of a connecting rod 51.

Referring to fig. 3, further, the guiding device 3 includes a housing 31, the housing 31 is used for being fixedly connected to the wall-attached device 2, a cavity 32 is disposed in the housing 31, a nut post 33 is disposed in the cavity 32, and the nut post 33 is in threaded engagement with the connecting rod 51.

It should be noted that the nut stem 33 is rotatable within the cavity 32.

In order to facilitate the rotation of the nut column 33, the outer surface of the nut column 33 is in a gear structure, the surface of the shell 31 is provided with an adjusting gear 34, the adjusting gear 34 penetrates through the shell 31 to extend into the cavity 32 and is rotatably connected with the shell 31, and the adjusting gear 34 is meshed with the outer surface of the nut column 33.

It is understood that the nut post 33 has an inner wall thread structure and an outer surface gear structure, and the nut post 33 can be rotated by rotating the adjusting gear 34.

It should be noted that, because the chain 4 is arranged on the chain wheel 5, it is difficult to rotate the chain wheel 5 during installation, the nut column 33 is rotated and connected with the connecting rod 51 with external threads, so that the connecting rod 51 or the chain wheel 5 does not need to be rotated, and the installation difficulty is reduced.

In the practical use process, after the frame body 1 is lifted to another height, the frame body 1 can be fixed on the wall of a building in a bolt mode and the like, at the moment, the chain 4 can be considered to be in a loose state, large pulling force cannot be generated, the adjusting gear 34 can be easily rotated, the nut column 33 is driven to rotate, and the chain wheel 5 is detached.

Referring to fig. 4 and 5, a second embodiment of the present invention provides an attached lifting scaffold, which is different from the first embodiment in the following.

Specifically, the nut post 33 is divided into a first half nut 331 and a second half nut 332 along a plane where an axis thereof is located, the housing 31 includes a main body 311 and a cover plate 312, the main body 311 and the cover plate 312 are mutually fastened to form the cavity 32, the cavity 32 is a cylindrical cavity, and when the main body 311 and the cover plate 312 are fastened, a relative position between the first half nut 331 and the second half nut 332 is not changed.

It should be noted that when the cover plate 312 is fastened, the relative position between the first half nut 331 and the second half nut 332 is not changed, which can be understood as a whole, and both are tightly connected with the connecting rod 51, when the cover plate 312 is loosened or disassembled, the first half nut 331 and the second half nut 332 are also loosened, and at this time, the connecting rod 51 can be easily pulled out, so as to realize the quick disassembly of the sprocket 5.

In practical use, a guide device 3 is required to be arranged on each wall attaching device 2.

Specifically, the main body 311 and the cover plate 312 are detachably connected by bolts 313.

In order to facilitate the rotation of the nut stud 3 in the cavity 32, the upper ends of the first half nut 331 and the second half nut 332 are provided with half rings 333, and the outer diameter of the half rings 333 is larger than the maximum radius of the first half nut 333. In other embodiments, the half ring 333 may be disposed at the lower end of the first half nut 331 and the second half nut 332, so that the gear portions of the first half nut 331 and the second half nut 332 do not directly contact the inner wall of the main body 311.

Similarly, the outer diameter of the half ring 333 is larger than the maximum radius of the second half nut 332, and in this embodiment, it is only slightly larger, such as 1 cm.

It should be noted that the presence of the half ring 333 prevents the gear structure of the nut stem 3 from coming into contact with the inner wall of the cavity 32, preventing damage to the outer surface of the nut stem 3.

Referring to fig. 6, in order to prevent the misalignment between the first half nut 331 and the second half nut 332, a first positioning column 334 and a first positioning groove 335 are disposed on the first half nut 331 facing the second half nut 332, a second positioning column 336 and a second positioning groove 335 are disposed on the second half nut 332 facing the first half nut 331, the first positioning column 334 is slidably engaged with the second positioning groove 337, and the second positioning column 336 is slidably engaged with the first positioning groove 335.

Furthermore, a plurality of balls 314 are disposed on the inner wall of the main body 311 at positions corresponding to the half rings 333, the balls 314 are rotatably connected to the main body 311, and the balls 314 are protruded.

It will be appreciated that the presence of balls 314, which allow rolling contact between the part of half 333 and the inner wall of cavity 32, reduces the friction and makes it easier to turn threaded stud 3.

In order to facilitate the installation of the connecting rod 51, the lower opening of the nut post 33 is of a gradually expanding opening structure.
