They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] like Figures 1 to 4As shown, a simple lift for low-rise building construction includes a top plate 1, two support frames 2 are hinged on the bottom surface of the top plate 1, a pedal 7 for stepping is fixedly connected to the surface of the support frame 2, a bottom support assembly 3 is arranged at the bottom of the support frame 2, a locking assembly 4 is arranged between two adjacent bottom support assemblies 3, and a diagonal brace assembly 5 is arranged on the front and back of the support frame 2. A telescopic control assembly 6 for controlling the length of the diagonal brace assembly 5 is arranged on the surface of the diagonal brace assembly 5. More specifically, after the support frame 2 is unfolded, the user can step on the pedal 7 to perform a high-altitude operation, the bottom of the support frame 2 is supported by the bottom support assembly 3 to increase the contact area with the ground, the bottom support assembly 3 can be locked by the locking assembly 4 to prevent the bottom support assembly 3 from shaking, thereby limiting the unfolding angle of the support frame 2, and the length of the diagonal brace assembly 5 is controlled by the telescopic control assembly 6 so that the diagonal brace assembly 5 can touch the ground, and the diagonal brace assembly 5 is used to support both sides of the support frame 2.

[0025] The bottom support assembly 3 includes a support plate 301, the inner wall of the support plate 301 is fixedly connected with a support shaft 303, and the support shaft 303 is rotatably connected to the support frame 2, and the bottom surface of the support plate 301 is fixedly connected with a first anti-skid pad 302, and the first anti-skid pad 302 is made of rubber. It should be noted that the support plate 301 is in contact with the ground, increasing the contact area with the ground, making the placement more stable, and the first anti-skid pad 302 made of rubber is provided to further increase the friction with the ground to prevent the elevator from shaking.

[0026] The locking assembly 4 includes a sliding rod 401, and the sliding rod 401 is fixedly connected to one of the support plates 301, a sleeve 402 is fixedly connected to the surface of the other support plate 301, and the sliding rod 401 is movably plugged into the sleeve 402, an insertion rod 406 is movably plugged into the surface of the sleeve 402, one end of the insertion rod 406 is fixedly connected to a shift block 403, the shift block 403 and the sleeve 402 bracket are fixedly connected with a spring 404, a positioning hole 405 is opened through the surface of the sliding rod 401, and the inner wall of the positioning hole 405 is movably plugged into the other end of the insertion rod 406. More specifically, pulling the shift block 403 causes the spring 404 to be compressed, and at the same time drives the end of the insertion rod 406 to separate from the inner wall of the positioning hole 405, thereby releasing the limit on the slide bar 401, and unfolding the support frame 2 will drive the two support plates 301 to move away from each other, and the support plate 301 will drive the slide bar 401 to slide along the inner wall of the sleeve 402. After the unfolding is completed, the shift block 403 is released, and the elastic force of the spring 404 will push the shift block 403 and the insertion rod 406 to move, so that the insertion rod 406 is reinserted into the inner wall of the positioning hole 405, and the slide bar 401 is limited again, so that the two support plates 301 can no longer move relative to each other, thereby keeping the support plate 301 stable.

[0027] The diagonal brace assembly 5 includes a support tube 501, and the support tube 501 is rotatably connected to the surface of the support frame 2. A support rod 502 is movably inserted into the inner wall of the support tube 501, and a cushion block 503 is fixedly connected to the end of the support rod 502. It should be noted that when the support frame 2 is unfolded, the support rod 502 is controlled by the telescopic control assembly 6 to slide along the inner wall of the support tube 501, so that the cushion block 503 comes into contact with the ground, thereby providing lateral support to the support frame 2 to prevent the support frame 2 from tipping over.

[0028] The telescopic control assembly 6 includes a threaded column 601, and the threaded column 601 is rotatably connected to the support tube 501, and the threaded column 601 is threadedly connected to the support rod 502.

More specifically, by rotating the knob 604, the worm 602 is driven to rotate, and then the worm wheel 603 meshed therewith is driven to rotate, so that the threaded column 601 can be controlled to rotate, and under the action of the threads on the surface of the threaded column 601, the support rod 502 will be driven to slide along the inner wall of the support tube 501.

[0029] The surface of the pedal 7 is fixedly connected with a second anti-skid pad 8, and the second anti-skid pad 8 is made of rubber. It should be noted that by providing the second anti-skid pad 8 of rubber material, the friction with the user's feet is increased, making the user more stable when standing on the surface of the pedal 7.

[0030] In summary: after the support frame 2 is unfolded, the user can step on the pedal 7 to perform climbing operations, and the bottom of the support frame 2 can be supported by the bottom support assembly 3 to increase the contact area with the ground.

The length of the diagonal brace assembly 5 is controlled by the telescopic control assembly 6 so that the diagonal brace assembly 5 can touch the ground, and the diagonal brace assembly 5 is used to support both sides of the support frame 2. During use, the effect of facilitating stable support of the elevator is achieved, making the elevator more stable when placed on the ground and not prone to tilting. It can remain stable without the support of others, thereby improving the safety of the elevator.
