DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 A kind of assembled subway integrated support and hanger base, including an annular seat 1 and a U-shaped seat 2, the upper surface of the U-shaped seat 2 is fixedly connected with a circular plate 3, the inner surface of the annular seat 1 is fixedly connected with an annular block 6, a plurality of rolling balls 8 are rotatably connected to the annular block 6, the surface of each rolling ball 8 is in contact with the surface of the U-shaped seat 2, an annular opening 9 is provided on the annular seat 1, a plurality of mounting blocks 10 are fixedly connected to the lower inner wall of the annular opening 9, a limiting component is arranged in each mounting block 10, the limiting component includes a limiting piece 14 slidably arranged on the mounting block 10, a rotating piece 12 is arranged on one side of the limiting piece 14, a plurality of card grooves for connecting the limiting piece 14 are arranged on the outer surface of the circular plate 3, an annular plate 4 is slidably connected in the annular opening 9, and a plurality of extrusion rods 11 are fixedly connected to the bottom surface of the annular plate 4.

[0023] The cross section of each limiting piece 14 is set in a T shape, and each limiting piece 14 is sleeved with a spring 15, one end of the spring 15 is fixedly connected to the limiting piece 14, and the other end of the spring 15 is fixedly connected to the mounting block 10. A slide groove 16 is opened on one side of each limiting piece 14, and a slider 13 is slidably connected in the slide groove 16. One end of the rotating piece 12 is hinged to the slider 13, and the other end of the rotating piece 12 is rotatably connected to the mounting block 10. The cross sections of the slide groove 16 and the slider 13 are set in a convex shape. The lower end of the extrusion rod 11 is in contact with the surface of the rotating piece 12, and the convex slider 13 will not separate from the slide groove 16. In the process of each extrusion rod 11 moving downward and against the surface of the corresponding rotating piece 12, the rotating piece 12 and the mounting block 10 will rotate relative to each other, and the slider 13 will slide in the slide groove 16 at the same time. Under the transmission action of the slider 13, the limiting piece 14 and the mounting block 10 will slide relative to each other at the same time, and the spring 15 will deform.

[0024] A plurality of positioning rods 7 are fixedly connected to the lower surface of the annular plate 4, and each positioning rod 7 is slidably connected to the annular seat 1. The positioning rods 7 can limit the moving trajectory of the annular plate 4 so that the annular plate 4 can stably move up and down in the annular opening 9. Two ear plates are fixedly connected to the annular plate 4, and each ear plate is connected to the annular seat 1 by a bolt 5. Two annular grooves are provided on the annular seat 1. One end of the bolt 5 is passed through the ear plate and threadedly connected to the thread groove, so that the annular plate 4 and the annular seat 1 can be firmly connected together to avoid relative movement between the annular plate 4 and the annular seat 1.

[0025] In the utility model, when in use, first insert the U-shaped seat 2 into the middle of the annular seat 1 until the lower surface of the circular plate 3 and the upper surface of the annular block 6 fit together. At this time, each rolling ball 8 is in contact with the outer surface of the U-shaped seat 2. When the annular seat 1 hits the steel bar during the punching process, the annular seat 1 can be rotated. The rolling ball 8 can effectively improve the smoothness of the rotation of the annular seat 1. The annular seat 1 and the U-shaped seat 2 rotate relative to each other, so that the punching position of the annular seat 1 can be staggered with the steel bar. After adjusting the position, press the annular plate 4 downward, and the positioning rod 7 and the annular seat at the same time. 1 slides relative to each other, and each extrusion rod 11 moves against the surface of the corresponding rotating piece 12 during the downward movement, thereby causing the rotating piece 12 and the mounting block 10 to rotate relative to each other. Under the transmission action of the slider 13, the limiting piece 14 slides relative to the mounting block 10 at the same time, and the spring 15 deforms until one end of the limiting piece 14 is engaged with the corresponding slot, thereby preventing the annular seat 1 and the U-shaped seat 2 from rotating relative to each other. The operation is relatively convenient and quick, and the installation efficiency of the comprehensive support and hanger base is high, which is conducive to the use of the comprehensive support and hanger base.

[0026] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.
