Positioning sliders 501 matching the limit groove 201 are provided on the front and rear sides of the gentle slope section 5 and slide in the limit groove 201. A positioning mechanism 6 is provided on the adjustment frame 2 for positioning the positioning slider 501, and the right end of the ramp 3 is hinged to the gentle slope section 5 through a hinged rod.

[0023] Further as Figure 2 、 Figure 3 and Figure 4 As shown, it is worth mentioning that the adjustment limit mechanism 4 includes an adjustment column 401, which is fixedly connected to the top of the movable block 103 and is arranged on the upper part of the bottom frame 1, and a flat slope section 402 is provided on the adjustment column 401. The front and rear sides of the flat slope section 402 are fixedly connected to a slider 403 and are slidably arranged on the adjustment column 401. Positioning holes 404 are opened through the front and rear side surfaces of the adjustment column 401. The front and rear side surfaces of the adjustment column 401 are fixedly connected to a limit frame 405, and a limit block 406 is slidably arranged in the limit frame 405. A limit rod 407 is fixedly connected to the limit block 406 near the four corners. The limit block 406 The limit rod 407 is slidably arranged in the limit frame 405, and a spring 408 is sleeved on the outside of the limit rod 407 and is arranged on the inside of the limit frame 405. An adjustment slot 409 is provided on the limit block 406, and an adjustment plate 4010 is slidably arranged in the adjustment slot 409. A positioning rod 4011 is fixedly connected to the adjustment plate 4010 and matches the positioning port 404. The adjustment column 401 is U-shaped, and the flat slope section 402 is arranged in the adjustment column 401 and is hinged to the ramp 3 through a hinged rod. A positioning hole matching the positioning port 404 and the positioning rod 4011 is provided on the slider 403, and the limit rod 407 is arranged through the limit frame 405.

[0024] When in use, the slider 403 slides in the adjustment column 401, and the flat slope section 402 drives the left end of the ramp 3 to move upward, thereby forming the angle adjustment of the ramp 3. At the same time, the elastic force of the spring 408 causes the limit block 406 to slide in the limit frame 405, so that the positioning rod 4011 passes through the positioning port 404 to position the slider 403, and the positioning rod 4011 can be slid to slide in the adjustment groove 409 through the adjustment plate 4010, thereby facilitating adaptive adjustment of its adjustment position, thereby improving the convenience of the adjustment process. At the same time, through the operation of the motor 101, the threaded rod 102 rotates, driving the movable block 103 to slide in the bottom frame 1, thereby causing the adjustment column 401 to slide through the movable block 103, thereby facilitating the position adjustment of the adjustment limit mechanism 4, so as to further adjust the angle of the ramp 3, so that the angle of the ramp 3 can always meet the design specifications according to the design specifications, thereby improving the practicality of the device.

[0025] According to the above working process, it can be seen that: by setting the adjustment limit mechanism 4, when adjusting the angle of the ramp 3, it can be ensured that the adjusted angle of the ramp 3 meets the design specification requirements, and the adjustment process is convenient and fast, and convenient positioning work can be performed during adjustment, thereby improving the practicality of the device.

[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the positioning mechanism 6 includes an electric telescopic rod 601, a limiting opening 602 and a limiting column 603. The electric telescopic rod 601 is fixedly installed on the left side of the adjustment frame 2. The right end of the electric telescopic rod 601 is connected to the left side of the gentle slope section 5. The limiting opening 602 is opened on the adjustment frame 2. The limiting column 603 matches the limiting opening 602 and is provided to position the positioning slider 501. A plurality of limiting openings 602 are evenly opened on the adjustment frame 2, and the plurality of limiting openings 602 are symmetrically arranged on the adjustment frame 2 front and back.

[0027] When in use, the electric telescopic rod 601 is operated to make the gentle slope section 5 slide on the inner side of the adjustment frame 2 through the positioning slider 501, and then the gentle slope section 5 drives one side of the ramp 3 to slide, so as to adapt the slope length of the ramp 3 according to the adjustment state of the ramp 3 to make it meet the design specifications. At the same time, the limiting column 603 is aligned with the limiting mouth 602, so that the limiting column 603 limits the positioning slider 501, thereby positioning the gentle slope section 5 and improving its stability after adjustment.

[0028] This solution has the following working process: when this device is in use, the device is positioned and installed through the bottom frame 1 and the adjustment frame 2. When the ramp 3 needs to be adjusted, the slider 403 slides in the adjustment column 401, and the flat slope section 402 drives the left end of the ramp 3 to move upward, thereby forming an angle adjustment of the ramp 3. At the same time, the elastic force of the spring 408 makes the limit block 406 slide in the limit frame 405, so that the positioning rod 4011 passes through the positioning port 404 to position the slider 403, and the positioning rod 4011 can be slid to slide in the adjustment slot 409 through the adjustment plate 4010, thereby facilitating adaptive adjustment of its adjustment position, thereby improving the convenience of the adjustment process. At the same time, through the operation of the motor 101, the movable block 103 is driven at the bottom under the rotation of the threaded rod 102. The frame 1 slides, and then the adjusting column 401 slides through the movable block 103, so as to facilitate the adjustment of the position of the adjustment limit mechanism 4, so as to further adjust the angle of the ramp 3. At this time, in conjunction with the setting of the positioning mechanism 6, the electric telescopic rod 601 is operated, so that the gentle slope section 5 slides on the inside of the adjustment frame 2 through the positioning slider 501, and then the gentle slope section 5 drives one side of the ramp 3 to slide, so as to adapt the slope length of the ramp 3 according to the adjustment state of the ramp 3 to meet the design specifications. At the same time, the limiting column 603 is aligned with the limiting mouth 602, so that the limiting column 603 limits the positioning slider 501, so that the position of the gentle slope section 5 can be positioned, thereby improving its stability after adjustment, and through the gentle slope section 5 cooperating with the ramp 3 and the flat slope section 402, the convenience of using the device can be improved.

[0029] In summary: by setting up the adjustment limit mechanism 4, when adjusting the angle of the ramp 3, it can be ensured that the adjusted angle of the ramp 3 meets the design specification requirements, and the adjustment process is convenient and quick, and convenient positioning work can be performed during adjustment, thereby improving the practicality of the device; by setting up the positioning mechanism 6, while cooperating with the adjustment limit mechanism 4 to adjust the angle of the ramp 3, the slope length can be matched and adjusted according to its actual adjustment process, and positioning work is facilitated at the same time, thereby improving its convenience during the adjustment process.
