[0009] Figure 2 It is a structural schematic diagram of an anti-slip stopper for a safe lifting stage according to a specific embodiment of the present invention. DETAILED DESCRIPTION
[0010] The following is a description of the embodiments, and further details are given of the specific implementation methods of the present invention, such as the shapes and structures of the components involved, the relative positions and connection relationships between the components, the functions and working principles of the components, the manufacturing process and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention.
[0011] The present invention provides a safe lifting stage, which comprises a base 1, a telescopic rod 2 arranged on the base 1 and a lifting stage body 3 arranged on the telescopic rod 2.
[0012] The base 1 is arranged on the ground, the lower end of the telescopic rod 2 is arranged on the upper surface of the base 1, and the lifting stage body 3 is arranged on the upper end of the telescopic rod 2. The axis of the telescopic rod 2 is perpendicular to the horizontal plane, and the two ends of the telescopic rod 2 are respectively fixedly connected to the base 1 and the lifting stage body 3, and the lifting stage body 3 can achieve the function of lifting up and down by extending and shortening the telescopic rod 2.
[0013] In order to prevent the lifting stage body 3 from suddenly falling due to the telescopic rod 2 during the lifting or lowering process, the safe lifting stage further includes a safety module. The safety module includes a safety rack 5 arranged on the lifting stage body 3, a safety column 4 arranged on the base 1, and an anti-slip block 6 arranged on the safety column 4 and cooperating with the safety rack 5.
[0014] The safety rack 5 is provided with a safety tooth, the side of the safety tooth pointing to the base 1 is parallel to the horizontal plane, the side of the safety tooth away from the base 1 and the horizontal plane form an acute angle, the section of the safety tooth is a right triangle, one of the right-angled sides is connected to the side wall of the lifting stage body 3, one of the right-angled sides is parallel to the horizontal plane, and the hypotenuse is away from the base 1.
[0015] The safety column 4 is perpendicular to the horizontal plane, and its lower end is fixedly connected to the base 1 . The anti-slip stopper 6 is arranged on the side of the safety column 4 pointing to the lifting stage body 3 .
[0016] The anti-slip block 6 includes a fixed block arranged on the safety column 4, a sliding block arranged on the fixed block, a blocking block arranged on the sliding block, a spring connecting the blocking block and the sliding block, and a second telescopic rod connecting the sliding block and the fixed block.
[0017] A sliding track is provided on the upper surface of the fixed block, and the cross-section of the sliding track is in the shape of a dovetail groove. A protruding rail inserted into the sliding track is provided on the side of the sliding block that contacts the fixed block, and the cross-section of the protruding rail is in the shape of a dovetail groove. A mounting seat is provided on the end of the fixed block connected to the safety column 4, and one end of the second telescopic rod is arranged on the mounting seat, and the end of the second telescopic rod away from the mounting seat is fixedly connected to the sliding block, and the movement of the sliding block on the sliding track is controlled by the extension and shortening of the second telescopic rod.
[0018] The end of the sliding block close to the safety column 4 is connected to the end of the blocking block close to the safety column 4 through a hinge. The two ends of the spring are respectively connected to the end of the sliding block away from the hinge and the end of the blocking block away from the hinge, and the tension of the spring promotes the blocking block to fit the sliding block. The end of the blocking block close to the lifting stage body 3 extends out of the end of the sliding block.
[0019] When the lifting stage body 3 needs to rise, the second telescopic rod is extended, so that the end of the blocking block close to the lifting stage body 3 is inserted between the safety teeth of the safety rack 5. When the lifting stage body 3 rises, the blocking block will rotate around the hinge and then rise smoothly. Once an accident occurs with the telescopic rod 2, causing the lifting stage body 3 to fall accidentally, the blocking block will prevent the lifting stage body 3 from falling, thereby achieving a safety protection effect.
[0020] When the lifting stage body 3 needs to be lowered, the second telescopic rod is retracted, so that the end of the blocking block close to the lifting stage body 3 is out of contact with the safety rack 5, and the lifting stage body 3 is smoothly retracted under the belt of the telescopic rod 2.
[0021] The above is an exemplary description of the present invention. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention. The protection scope of the present invention shall be based on the protection scope defined in the claims.
