[0037] Referring to Figure 1 The lower ladder body 12 comprises two second vertical rods 121 and a plurality of second foot pedal rods 122, the two second vertical rods 121 are arranged at intervals, the plurality of second foot pedal rods 122 are arranged at intervals, in the embodiment, four second foot pedal rods 122 are arranged at intervals, any second foot pedal rod 122 is arranged between the two second vertical rods 121, and one end of any second foot pedal rod 122 is welded to the second vertical rod 121.

[0038] Referring to Figure 2 and Figure 3The main frame body 1 is symmetrically provided with rotating assemblies 2. Since the structures and connection modes of the two rotating assemblies 2 are the same, one of the rotating assemblies 2 is taken as an example for illustration. The rotating assembly 2 comprises an upper connecting plate 21, a lower connecting plate 22 and a rotating rod 23. The upper connecting plate 21 is welded on the first vertical rod 111 of the upper ladder body 11, the lower connecting plate 22 is welded on the second vertical rod 121 of the lower ladder body 12, and the rotating rod 23 is welded on the lower connecting plate 22. The upper connecting plate 21 is rotationally connected to the rotating rod 23, i.e. the first vertical rod 111 rotates around the central axis of the rotating rod 23, so that the upper ladder body 11 can rotate relative to the lower ladder body 12.

[0039] With reference to Figure 1 and Figure 4 The first vertical rod 111 of the upper ladder body 11 is provided with reinforcing assemblies 113 for reinforcing the connection stability between the upper ladder body 11 and the lower ladder body 12. The reinforcing assemblies 113 are symmetrically provided with two assemblies. Since the structures and connection modes of the two reinforcing assemblies 113 are the same, one of the reinforcing assemblies 113 is taken as an example for illustration.

[0040] With reference to Figure 1 and Figure 4 The reinforcing assembly 113 comprises a sliding block 1131 and a fixing bolt 1132 for locking the sliding block 1131. The first vertical rod 111 of the upper ladder body 11 and the second vertical rod 121 of the lower ladder body 12 are jointly provided with a sliding groove 1111, which is arranged at the connection between the first vertical rod 111 and the second vertical rod 121. The sliding block 1131 is slidingly arranged in the sliding groove 1111. The first vertical rod 111 is provided with a fixing hole 1112, and the fixing bolt 1132 is threadedly connected in the fixing hole 1112. The fixing bolt 1132 penetrates the sliding block 1131 and is locked by a nut.

[0041] With reference to Figure 1 and Figure 4 When the staff needs to normally use the ladder, i.e. at this time, the upper ladder body 11 and the lower ladder body 12 are arranged in the same horizontal plane, the two sliding blocks 1131 are slid to the connection between the first vertical rod 111 and the second vertical rod 121, i.e. the upper surface of any sliding block 1131 is abutted with the top of the sliding groove 1111 of the upper ladder body 11, and the sliding block 1131 is locked and fixed on the first vertical rod 111 of the upper ladder body 11 by the fixing bolt 1132. At this time, the sliding block 1131 can block the rotation of the upper ladder body 11 relative to the lower ladder body 12, so as to ensure the connection stability between the upper ladder body 11 and the lower ladder body 12 and improve the overall safety of the ladder.

[0042] With reference to Figure 1 and Figure 4When it is necessary to rotate or store the ladder body 11, the two sliding blocks 1131 are completely slid into the sliding grooves 1111 of the second vertical rods 121, that is, the lower surfaces of the sliding blocks 1131 abut against the bottoms of the sliding grooves 1111 of the second vertical rods 121, so that the ladder body 11 can be rotated relative to the lower ladder body 12, thereby facilitating use or storage by the staff.

[0043] With reference to Figure 2 and Figure 5 , the second vertical rod 121 is rotationally connected with a support assembly 123, the support assembly 123 is used for connecting an outer wall of a building or used for connecting the first vertical rod 111, the support assembly 123 is provided with four, the four support assemblies 123 are symmetrically arranged in pairs, and any one of the support assemblies 123 is detachably connected with the ladder body 11 away from the lower ladder body 12. Since the structures and connection modes of the four support assemblies 123 are the same, one of the support assemblies 123 will be taken as an example for description.

[0044] With reference to Figure 2 and Figure 5 , the support assembly 123 comprises a first support rod 1231, a first telescopic rod 1232 and a connecting structure 1233. The first support rod 1231 is rotationally connected with the second vertical rod 121. The first support rod 1231 is provided with a first telescopic groove 12311. The first telescopic rod 1232 is telescopically slid in the first telescopic groove 12311. The connecting structure 1233 is detachably connected with the first telescopic rod 1232 away from the support rod. The first support rod 1231 is provided with a first limiting bolt 12312 away from the lower ladder body 12. The first telescopic rod 1232 is provided with a first limiting hole 12321 and a second limiting hole 12322 which can be threadedly connected with the first limiting bolt 12312.

[0045] With reference to Figure 2 and Figure 5 , the first support rod 1231 is rotationally connected with the second vertical rod 121, and the first telescopic rod 1232 is telescopically slid in the first telescopic groove 12311 of the first support rod 1231. When the first limiting bolt 12312 is threadedly connected with the first limiting hole 12321, the first telescopic rod 1232 is in a retracted state. When the first limiting bolt 12312 is threadedly connected with the second limiting hole 12322, the first telescopic rod 1232 is in an extended state. Thus, the staff can adjust and fix the length of the first telescopic rod 1232 through the first limiting bolt 12312, so that the connecting structure 1233 can be adjusted in position as needed, thereby adapting to the needs of different outer walls of buildings. Meanwhile, the telescopic arrangement of the first telescopic rod 1232 facilitates its retraction and storage by the staff.

[0046] With reference to Figure 5 andFigure 6 The connecting structure 1233 is threadedly connected to the first telescopic rod 1232 at the end away from the first support rod 1231. Since the connecting structure 1233 is detachably arranged, when it is required to abut the connecting structure 1233 against the outer wall of a higher building, the connecting structure 1233 is arranged as an abutting frame 12331, which is threadedly connected to the outer wall of the building. The abutting frame 12331 increases the contact area between the support assembly 123 and the outer wall of the building, thereby improving the connection stability between the abutting frame 12331 and the building, and further ensuring the stability and safety of the workers during the climbing process.

[0047] Referring to Figure 2 and Figure 5 When it is required to connect the connecting structure 1233 to the first vertical rod 111, i.e., the upper ladder body 11 and the lower ladder body 12 are rotated to the shape of an inverted ladder, and the two first vertical rods 111 of the upper ladder body 11 are stably placed on the ground, the connecting structure 1233 is arranged as a connecting frame 12332, which is provided with an open slot 123321 for clamping the first vertical rod 111. The connecting frame 12332 is provided with a locking bolt 12333 for locking the open slot 123321. In use, the locking bolt 12333 is arranged through the first vertical rod 111 in the connecting frame 12332 and the open slot 123321, and a nut is used to reduce the possibility of loosening of the locking bolt 12333, thereby achieving the connection and fixation between the upper ladder body 11 and the lower ladder body 12, which is suitable for the working scenario of workers performing building operations at a lower height.

[0048] Referring to Figure 5 The second vertical rod 121 on each side of the lower ladder body 12 is provided with a stability assembly 124 for strengthening the stability of the second vertical rod 121. Since the structure and connection mode of the two stability assemblies 124 are the same, one of the stability assemblies 124 will be described as an example.

[0049] Referring to Figure 5 The stability assembly 124 comprises a second support rod 1241 and a second telescopic rod 1242. The second support rod 1241 is rotationally connected to the second vertical rod 121, and is provided with a second telescopic slot 12411. The second telescopic rod 1242 telescopically slides in the second telescopic slot 12411, and the end of the second telescopic rod 1242 away from the second support rod 1241 abuts against the ground.

[0050] Referring to Figure 5The second supporting rod 1241 is provided with a second limiting bolt 12412 at one end away from the second vertical rod 121, and the second telescopic rod 1242 is provided with a third limiting hole 12421 and a fourth limiting hole 12422 which can be threadedly connected with the second limiting bolt 12412, when the second limiting bolt 12412 is threadedly connected with the third limiting hole 12421, the second telescopic rod 1242 is in a retracted state, and when the second limiting bolt 12412 is threadedly connected with the fourth limiting hole 12422, the second telescopic rod 1242 is in an extended state, so that the length of the second telescopic rod 1242 can be adjusted and fixed by the second limiting bolt 12412, and the telescopic arrangement of the second telescopic rod 1242 facilitates its retraction and storage.

[0051] With reference to Figure 1 The first supporting plate 1113 and the second supporting plate 1211 are in abutting engagement with the ground, when the first vertical rod 111 and the second vertical rod 121 are in the shape of a ladder, the first supporting plate 1113 and the second supporting plate 1211 enable the first vertical rod 111 and the second vertical rod 121 to be stably placed on the ground, so that the workers can stand on the first footrest rod 112 and the second footrest rod 122 to perform building work safely and stably.

[0052] The implementation principle of the embodiment of the application is that when the workers need to perform building work at a higher height, first, the two sliding blocks 1131 are slid to the connecting part between the first vertical rod 111 and the second vertical rod 121, and the sliding blocks 1131 are locked and fixed on the first vertical rod 111 of the ladder body 11 by the fixing bolts 1132, then the first limiting bolt 12312 is connected and fixed with the second telescopic hole of the first telescopic rod 1232, so that the first telescopic rod 1232 is in an extended state, the first supporting rod 1231 is rotated to a suitable angle, the abutting frame 12331 on the first telescopic rod 1232 is fixed on the outer wall of the building by the bolt, then the second limiting bolt 12412 is connected and fixed with the fourth limiting hole 12422 of the second telescopic rod 1242, so that the second telescopic rod 1242 is in an extended state and stably abuts on the bottom surface, so that the workers can perform climbing work safely and stably.

[0053] When the workers need to perform the building work at a lower height, the two sliding blocks 1131 are first operated to completely slide into the sliding grooves 1111 of the second vertical rods 121, then the ladder body 11 is rotated, so that the first support plates 1113 on the first vertical rods 111 are rotated to stably abut against the ground, then the connecting frame 12332 is clamped on the first vertical rods 111, and the first vertical rods 111 are penetrated by the locking bolts 12333 and the opening grooves 123321 of the connecting frame 12332, so as to realize the connection between the first telescopic rods 1232 and the first vertical rods 111, and further realize the stable connection between the ladder body 11 and the lower ladder body 12, then the second limiting bolt 12412 is connected and fixed with the fourth limiting hole 12422 of the second telescopic rod 1242, so that the second telescopic rod 1242 is in an extended state and stably abuts against the bottom surface, so that the workers can safely and stably perform the climbing work.

[0054] When the workers need to fold and store the main frame body 1, the abutting frame 12331 or the connecting frame 12332 is first removed, then the first limiting bolt 12312 is connected and fixed with the first telescopic hole of the first telescopic rod 1232, so that the first telescopic rod 1232 is in a retracted state, and the four first support rods 1231 are downwardly rotated to be close to the vertical state, then the second limiting bolt 12412 is connected and fixed with the third limiting hole 12421 of the second telescopic rod 1242, so that the second telescopic rod 1242 is in a retracted state, and the two second support rods 1241 are downwardly rotated to abut against the second vertical rods 121, then the two sliding blocks 1131 are operated to completely slide into the sliding grooves 1111 of the second vertical rods 121, then the ladder body 11 is rotated, so that the first vertical rods 111 of the ladder body 11 and the second vertical rods 121 of the lower ladder body 12 are in a close abutting state, thereby realizing the storage of the main frame body 1.
