DETAILED DESCRIPTION

[0023] In order to make the technical means, creation features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0024] As Figures 1-6 Indicated, the utility model provides a kind of supporting device for construction engineering, including main rod 1, rotatingly installed with rotating shaft 3 at the lower end of main rod 1, first backing plate 4 is connected with the shaft at the lower end of rotating shaft 3, a plurality of handles 5 are fixedly installed on the outer side of main rod 1, telescopic stud 6 is installed in the inside of main rod 1, second backing plate 7 is connected with the upper end of telescopic stud 6, base 8 is fixedly installed on the upper end of main rod 1, two plugboards 9 are movably installed in base 8, gasket 10 is respectively arranged on the opposite side of two plugboards 9, and compression spring 11 is movably connected between gasket 10 and plugboard 9, two semicircular clamping blocks 12 are arranged in base 8, connecting ring 14 is installed in the penetrating manner in the main rod 1 above handle 5, two plug rods 13 are fixedly installed on connecting ring 14.

[0025] The main rod 1 located above the connecting ring 14 is also provided with a screw groove 2, the base 8 is provided with a first displacement groove 15, both sides of the first displacement groove 15 are provided with a second displacement groove 16, and the lower end of the second displacement groove 16 penetrates the base 8. Through the arrangement of the base 8, the installation and displacement of the semicircular clamping block 12 can be provided. The opposite sides of the two semicircular clamping blocks 12 are respectively provided with a half-width screw groove 18, and the two half-width screw grooves 18 are combined into a ring-shaped screw hole structure. The middle of the side of the semicircular clamping block 12 away from the half-width screw groove 18 is fixedly installed with a pressure block 19. The semicircular clamping block 12 is inserted into the first displacement groove 15, and the pressure block 19 is inserted into the second displacement groove 16. Through the arrangement of the two separable semicircular clamping blocks 12, the quick pulling of the telescopic stud 6 in the main rod 1 can be realized. The side of the plug plate 9 is fixedly installed with a stop block 17. The plug plate 9 is inserted and installed in the second displacement groove 16, and the side of the plug plate 9 abuts against one side of the pressure block 19. The gasket 10 abuts against the other side of the pressure block 19, and the stop block 17 is arranged outside the base 8. The other end of the plug plate 9 also extends to the other side of the base 8 through the through groove in the inner side of the telescopic stud 6 and is limited by the plug pin. The side of the connecting ring 14 is threadedly connected with a fixing bolt 20. The ends of the two plug rods 13 away from the connecting ring 14 are respectively inserted into the corresponding second displacement grooves 16 and located below the pressure blocks 19.

[0026] It should be noted that this utility model is a support device for building engineering. Under normal circumstances, since the pressure block 19 passes through the internal through groove and is inserted into the outer side of the corresponding insert plate 9 and gasket 10, the pressure block 19 is inserted into the second displacement groove 16 by means of the supporting force of the compression spring 11, which can separate the semi-circular clamp 12 from the telescopic stud 6. At this time, the telescopic stud 6 can be manually pulled out quickly from the main rod 1 and pulled out to a suitable length. Then, the connecting ring 14 is pushed towards the base 8, so that the connecting ring 14 synchronously drives the two insert rods 13 to move. Then, the ends of the two insert rods 13 away from the connecting ring 14 move upward in the corresponding second displacement groove 16 and squeeze the corresponding pressure block 19 to one side. Then, the insert plate 9 moves towards the telescopic stud 6 after being squeezed by the insert rod 13, and the insert plate 9 also pushes the corresponding gasket 10 towards the insert plate through the internal through groove. The compression movement in direction 9 causes the pad 10 to compress the compression spring 11 towards the insert plate 9. Then, the fixing bolt 20 is rotated so that one end of the fixing bolt 20 is threaded into the screw groove 2, which limits the connection ring 14. Then, the two semi-circular clamping blocks 12 merge in the first displacement groove 15 and are threadedly connected to the telescopic stud 6. Then, the first pad 4 is fixed to the ground by the ground anchor, and the second pad 7 is similarly fixed to the supporting object by bolts. At this time, the telescopic stud 6 restricts the axial movement with the help of the second pad 7. At this time, the two handles 5 can be manually operated to rotate the main rod 1, so that the lower end of the main rod 1 rotates on the rotating shaft 3. This allows the main rod 1 to drive the two semi-circular clamping blocks 12 to rotate synchronously through the base 8, thereby further adjusting the telescopic stud 6 by a short distance, so that the overall length of the telescopic stud 6 and the main rod 1 gradually increases, thus providing stable support for the object.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
