[0002] The escalator displacement adjusting structure is a mechanical device used to adjust the position or direction of an escalator.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Such as Figure 1As shown in the figure, an escalator displacement adjustment mechanism includes an escalator body 1. A bottom of the escalator body 1 is fixedly provided with an adjustment structure 2, and a front part of the adjustment structure 2 is fixedly provided with a support structure 3.
[0025] By providing the adjustment structure 2, starting the first motor 22 drives the first lead screw 24 to rotate, thereby driving the rectangular frame 25 to slide left and right, and then realizing the displacement adjustment of the escalator body 1. The second motor 26 drives the bidirectional lead screw 27 to rotate, thereby driving the two sliders 28 to slide synchronously, and then making the distance between the two fixed frames 29 adapt to the distance at the bottom end of the escalator body 1. Through the interaction between the slider 28 and the fixed frame 29, the escalator body 1 can rotate. Then, under the action of the ratchet 211 and the clamping rod 212, the reverse rotation of the escalator body 1 is avoided, thereby improving the safety and practicability of the escalator body 1 during use.
[0026] As Figure 2 shown in the figure, the adjustment structure 2 includes a base 21. The base 21 is located below the escalator body 1. A middle part of a top end of the base 21 is provided with a chute 23. A right end of the base 21 is fixedly provided with a first motor 22. An output end of the first motor 22 extends into the chute 23. The output end of the first motor 22 is fixedly connected with a first lead screw 24. A left end of the first lead screw 24 is rotatably connected to a left end of the chute 23. An outer wall of the first lead screw 24 is threadedly connected with a rectangular frame 25. A bottom of the rectangular frame 25 is slidably connected to the inside of the chute 23.
[0027] By providing the first lead screw 24, starting the first motor 22 drives the first lead screw 24 to rotate, thereby driving the rectangular frame 25 to slide left and right, and then realizing the displacement adjustment of the escalator body 1.
[0028] As Figure 3 shown in the figure, a right end inside the rectangular frame 25 is rotatably connected with a bidirectional lead screw 27. A left end of the rectangular frame 25 is fixedly provided with a second motor 26. An output end of the second motor 26 extends into the rectangular frame 25. The output end of the second motor 26 is fixedly connected with a left end of the bidirectional lead screw 27. Left and right positions on an outer wall of the bidirectional lead screw 27 are both threadedly connected with sliders 28. Bottoms of the two sliders 28 are both slidably connected to the inside of the rectangular frame 25. Tops of the two sliders 28 are both rotatably connected with fixed frames 29. Inner parts of the two fixed frames 29 are respectively inserted into left and right positions at the bottom of the escalator body 1. A front end at the top of the rectangular frame 25 is fixedly connected with a magnet 210. The front end of the magnet 210 is magnetically connected to a rear end of the two fixed frames 29.
[0029] By setting the bidirectional lead screw 27, the second motor 26 drives the bidirectional lead screw 27 to rotate, thereby driving the synchronous sliding of the two sliders 28, so that the distance between the two fixed frames 29 is adapted to the distance at the bottom end of the escalator body 1, thus improving the versatility of the escalator displacement adjustment mechanism. The magnet 210 can adsorb the fixed frame 29, thereby assisting the insertion of the escalator body 1 into the fixed frame 29.
[0030] As Figure 3 shown, on the side where the bottom axles of the two fixed frames 29 are far away from each other, ratchets 211 are fixedly connected respectively. The two ratchets 211 are respectively located on the side where the tops of the two sliders 28 are far away from each other. Rotating connection rods 212 are respectively installed on the side where the tops of the two sliders 28 are far away from each other. The bottoms of the two rotating connection rods 212 are respectively lapped with the tops of the outer walls of the two ratchets 211.
[0031] By setting the ratchets 211 and the rotating connection rods 212, when the escalator body 1 shakes due to external factors, the straight surface at the bottom of the rotating connection rod 212 fits with the straight surface of the ratchet 211 and limits the ratchet 211, thereby preventing the escalator body 1 from reversing, and thus improving the safety and practicality of the escalator body 1 during use.
[0032] As Figure 2 and Figure 5 shown, the support structure 3 includes four first elastic telescopic rods 31. One ends of the four first elastic telescopic rods 31 close to the base 21 are respectively fixedly installed at the left and right positions of the front and rear parts of the base 21. The output ends of the four first elastic telescopic rods 31 are all fixedly connected with rectangular blocks 32. Second elastic telescopic rods 38 are fixedly installed on the opposite surfaces of the rectangular blocks 32 at the front and rear positions. The output ends of the four second elastic telescopic rods 38 are all fixedly connected with clamping blocks 39. Clamping frames 310 are fixedly connected to the left and right positions of the front and rear surfaces of the base 21.
[0033] By setting the clamping blocks 39 and the clamping frames 310, press the rectangular block 32 towards the base 21. At this time, the first elastic telescopic rod 31 is squeezed by force and contracts into the base 21. When the clamping block 39 contacts the clamping frame 310, due to the action of the inclined surface on the surface of the clamping block 39, the clamping block 39 is forced to expand and contract into the rectangular block 32. After that, when the clamping block 39 is completely separated from the clamping frame 310, under the action of the second elastic telescopic rod 38, the clamping block 39 is inserted into the clamping frame 310, thereby limiting the rectangular block 32, and thus realizing the overall folding of the support structure 3, reducing the space occupied by the escalator displacement adjustment mechanism, and improving the portability of the overall mechanism.
[0034] As Figure 4As shown in the figure, the middle parts of the four rectangular blocks 32 are all threadedly connected with second lead screws 33. The tops of the four second lead screws 33 are all fixedly connected with handles 34, the bottoms of the four second lead screws 33 are all fixedly connected with pressing blocks 35, and the bottoms of the four pressing blocks 35 are all rotatably connected with universal balls 36. The bottoms of the outer walls of the four universal balls 36 are all fixedly connected with support plates 37.
[0035] By setting the support plate 37, turning the handle 34 can drive the second lead screw 33 to rotate, so that the pressing block 35 and the support plate 37 press down on the ground. Under the action of the universal ball 36, the support plate 37 can be more closely attached to the ground for support, thereby improving the adaptability of the support structure 3 and further improving the support effect.
[0036] The working principle of the present utility model: When in use, start the second motor 26 to drive the bidirectional lead screw 27 to rotate, and then drive the two sliders 28 to slide synchronously, so that the distance between the two fixed frames 29 is adapted to the distance at the bottom end of the escalator body 1. Under the action of the magnets 210, the two fixed frames 29 are attached to the top of the rectangular frame 25. Then insert the two parts at the bottom end of the escalator body 1 into the two fixed frames 29 respectively. When the escalator body 1 needs to be used obliquely, the escalator body 1 rotates and leans on the wall or the scaffolding. The rotation of the escalator body 1 drives the fixed frame 29 to rotate, and then drives the ratchet 211 to rotate. At this time, the inclined surface of the ratchet 211 is in contact with and slides relative to the inclined surface of the clamping rod 212. When the escalator body 1 shakes due to external factors, the straight surface at the bottom of the clamping rod 212 is in contact with the straight surface of the ratchet 211 and limits the ratchet 211, thereby preventing the escalator body 1 from reversing, and further improving the safety and practicality of the use of the escalator body 1. When the displacement adjustment of the escalator body 1 is required, start the first motor 22 to drive the first lead screw 24 to rotate, and then drive the rectangular frame 25 to slide left and right, so as to realize the displacement adjustment of the escalator body 1. After the base 21 is placed stably, turn the handle 34 to drive the second lead screw 33 to rotate, so that the pressing block 35 and the support plate 37 press down on the ground. Under the action of the universal ball 36, the support plate 37 can be more closely attached to the ground for support, thereby improving the adaptability of the support structure 3 and further improving the support effect, and further improving the stability of the escalator displacement adjustment mechanism. When the escalator displacement adjustment mechanism needs to be carried, press the rectangular block 32 towards the base 21. At this time, the first elastic telescopic rod 31 is stressed and squeezed and retracts into the base 21. When the clamping block 39 contacts the clamping frame 310, under the action of the inclined surface on the surface of the clamping block 39, the clamping block 39 is stressed and retracts into the rectangular block 32. After the clamping block 39 is completely separated from the clamping frame 310, under the action of the second elastic telescopic rod 38, the clamping block 39 is inserted into the clamping frame 310 to limit the rectangular block 32, thereby realizing the overall folding of the support structure 3, reducing the space occupied by the escalator displacement adjustment mechanism, and improving the portability of the overall mechanism.
