Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
A mosaic plate platform maintenance tool main body comprises a screw rod 3, a butterfly nut 4, a round cover 5, a quadrilateral block 7, a transparent pipe 8, a nut A and a nut B; as shown in figure 2 of the drawings, in which,
the top end of the screw rod 3 is provided with a nut 1, a threaded screwing nut A2 is arranged between the nut 1 and the screw rod 3, a limiting butterfly nut 4 is arranged on the screw rod 3 through threaded connection, and the butterfly nut 4 can be separated from the screw rod 3 without the nut 1 and the nut A in the screwing process;
the butterfly nut 4 is screwed into the screw rod 3 through threads, and the screw rod 3 penetrates through the round cover 5 and extends into the transparent tube.
The quadrilateral block 7 is fixed at the bottom end of the screw rod 3 through a nut B6.
The transparent tube 8 and the round cover 5 are combined into a cylinder.
The position of the quadrilateral block 7 is lifted or lowered by rotating the butterfly nut 4 to change the position on the screw rod 3 during use, and only one mosaic with 42 × 24MM specification can be extracted due to the distance between the bottom surfaces of the cylinders formed by the transparent tube 8 and the round cover 5, so that the average stress of the disc surface is kept during disassembly and assembly, the force for rotating and lifting is gentle, and the design through the butterfly nut 4 is labor-saving, so that the stable taking process can be ensured, and the mosaic cannot be damaged.
The tool is simple and easy to use. The following steps are divided for detailed description:
(1) the quadrilateral blocks are clamped on the base of the disc table by rotating the butterfly nuts. The quadrilateral block is provided with an edge bulge, the width of the edge bulge is the same as that of a mosaic of the base of the coil platform, and the quadrilateral block is tightly attached to the base when the base is clamped.
(2) The quadrilateral block is fixed, and the screw rod is lifted upwards to drive the quadrilateral block to lift upwards by rotating the butterfly nut. The distance between the butterfly nut and the quadrilateral block is shortened along with the screw thread in the rotation process of the butterfly nut, and the disk surface is fixed by the transparent tube, so that the mosaic base is taken out along with the quadrilateral block.
(3) The quadrilateral block continues to rotate until removal. If the installation is that the rotation and the disk surface are kept horizontal.
