[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Figure 1 - Figure 4 As shown, the utility model provides a technical solution for a fast disassembly and assembly of a fixed ladder with a monorail structure, comprising a device body 1, the device body 1 comprising two vertical rods 2 and horizontal rods 3 distributed in a linear array, a track groove 4 penetrating to one side of the vertical rod 2 is provided at the top of the vertical rod 2, the horizontal cross section of the track groove 4 is a convex cavity, both ends of the horizontal rod 3 are fixedly connected with a fixing block, the horizontal cross section of the fixing block is a convex structure, the fixing block is slidably connected to the track groove 4, two connecting ropes 5 are fixedly connected between each adjacent horizontal rod 3, the upper part of the topmost horizontal rod 3 is fixedly connected with a top plate 6, a limiting component is provided on the vertical rod 2 to limit the movement of the bottommost horizontal rod 3 in the cavity of the track groove 4, and the width of the top plate 6 is greater than the width of the notch of the track groove 4;

[0022] During installation, you only need to slide the bottom cross bar 3 from the top of the two track grooves 4 into the cavity of the track groove 4. The top plate 6 will prevent the cross bar 3 from continuing to slide. Then the limiting component will limit the bottom cross bar 3, so that each cross bar 3 is installed between the two vertical bars 2.

[0023] like Figure 2 As shown, the vertical rod 2 includes two first long rods 201, and the corners of the ends of the two first long rods 201 are fixedly connected with a first shaft block 202 and two second shaft blocks 203 respectively, and the first shaft block 202 is rotatably connected between the two second shaft blocks 203;

[0024] The vertical rod 2 can be folded through the first long rod 201, which can shorten the length of the vertical rod 2. The two vertical rods 2 can only be folded in directions opposite to each other. In this way, after the cross bar 3 is installed, the cross bar 3 can also improve the installation stability of the two vertical rods 2, ensuring that the vertical rod 2 will not fold during use.

[0025] like Figure 2 and Figure 4 As shown, a slide rail 7 is installed on one side of the vertical rod 2, and a first slider 8 is slidably connected to the slide rail 7. A clamping assembly is provided on the first slider 8. A limiting hole is opened on one side of the first slider 8, and a limiting rod is threadedly connected to the limiting hole. The movable end of the limiting rod contacts the side wall of the slide rail 7.

[0026] like Figure 4 As shown, the clamping assembly includes two gears 9 rotatably connected to one side of the first slider 8, and the axis of the two gears 9 is fixedly connected to a first clamping jaw 10 and a second clamping jaw 11 respectively. A slide groove 12 is provided on one side of the first slider 8, and a second slider is slidably connected in the slide groove 12. A first connecting rod 13 is rotatably connected between the second slider and the two gears 9, and a second connecting rod 14 is rotatably connected to one side of the second slider. A control assembly for driving the second slider to slide in the slide groove 12 is provided on the device body 1. The first clamping jaw 10 and the second clamping jaw 11 are arranged in mirror symmetry with each other, and the second connecting rod 14 and the two first connecting rods 13 are staggered with each other in sequence.

[0027] In the initial state, the second slider is in a locked state, and the first clamping jaw 10 and the second clamping jaw 11 are both at an angle of 180 degrees and are distributed on the side of the ladder. The overall outline does not exceed the lower side of the ladder to prevent it from affecting the storage, transportation and lap joint of the ladder;

[0028] When in use, after putting the ladder to the corresponding position, first rotate the tightening screw assembly 18 counterclockwise to release the lock, so that the entire device can slide up and down. When the first clamping jaw 10 and the second clamping jaw 11 are visually observed to have slid to the appropriate position, the second connecting rod 14 is used to push the second slider to slide in the sliding groove 12, and the second slider uses the first connecting rod 13 to control the rotation of the first clamping jaw 10 and the second clamping jaw 11 until the channel steel support is clamped. After that, the tightening screw assembly 18 is used to lock the operating rod 15, and the entire device will not be able to slide up and down, and the clamping jaws cannot be opened, so that it will not loosen, turning the ladder into a fixed ladder.

[0029] like Figure 2 and Figure 4 As shown, the control assembly includes an operating rod 15, and a fixed card 17 is provided on the outer sliding sleeve of the operating rod 15. The fixed card 17 is fixedly connected to one side of the vertical rod 2. The movable end of the vertical rod 2 is rotatably connected to the movable end of the second connecting rod 14. A tightening screw component 18 that can limit the movement of the operating rod 15 on the fixing card 17 is provided on one side of the fixing card 17. The tightening screw component 18 includes a bolt, one end of the bolt is fixedly connected to a nut, and a threaded hole is opened on one side of the fixing card 17 to be threadedly connected to the other end of the bolt, and the other end of the bolt is in contact with one side of the insertion rod 16;

[0030] By pushing the operating rod 15, the operating rod 15 pushes the second connecting rod 14 to move, and the second connecting rod 14 pushes the second slider to slide in the sliding groove 12;

[0031] By rotating the bolt, the movable end of the bolt is pressed against and contacts the operating rod 15 , thereby fixing the operating rod 15 on the fixing clamp 17 .

[0032] like Figure 1 and Figure 3 As shown, the limiting assembly includes two insertion rods 16, one end of the insertion rod 16 is fixedly connected to a nut, a first insertion hole 19 and a threaded hole are respectively formed on the inner walls of both sides of the track groove 4, and two second insertion holes 20 are formed on the bottom cross bar 3. The movable end of the insertion rod 16 is provided with an external thread, and the movable end of the insertion rod 16 passes through the first insertion hole 19 and the second insertion hole 20 and is threadedly connected to the threaded hole;

[0033] After assembling the vertical rod 2 and the cross rod 3, the insertion rod 16 is passed through the first hole 19 and the second hole 20 in sequence and threadedly connected to the threaded hole. The insertion rod 16 can limit the movement of the cross rod 3 in the track groove 4. The cooperation of the insertion rod 16, the top plate 6 and the connecting rope 5 can stably fix the cross rod 3 between the two vertical rods 2.

[0034] like Figure 4 As shown, the operating rod 15 includes two second long rods 1501, one end of each of the two second long rods 1501 is respectively provided with a threaded groove and fixedly connected to a threaded rod 1502, and the threaded rod 1502 is threadedly connected to the threaded groove;

[0035] The two second long rods 1501 are provided to facilitate the folding of the vertical rod 2. When assembling the operating rod 15, it is only necessary to thread the threaded rod 1502 on the second long rod 1501 at the bottom to the threaded groove.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
