DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figures 1 to 4, a combined fan support is disclosed, comprising a plurality of base plates 1, a positioning cylinder 2 being fixed on the upper surface of the base plate 1, a detachable vertical rod 3 being fixed inside the positioning cylinder 2, a slide groove 31 being provided inside the top end of the vertical rod 3, and a screw rod 4 being slidably connected inside the slide groove 31, a transverse plate 7 and a longitudinal plate 8 being fixedly connected to the top end of the screw rod 4, a bracket assembly 9 for supporting steel bars being slidably connected on the surfaces of the transverse plate 7 and the longitudinal plate 8, a sleeve 5 for driving the screw rod 4 to rise and fall is provided on the top end surface of the vertical rod 3, and a docking assembly 11 is fixed between two adjacent base plates 1.

As shown in FIG. 1-FIG 2 , a through hole 21 is formed in the side wall of the positioning tube 2 and the bottom end of the vertical rod 3 , and a long bolt 22 is passed through the through hole 21 .

When assembling and splicing the base plate 1 and the vertical pole 3, insert the bottom end of the vertical pole 3 into the positioning tube 2, and align the through hole 21 at the bottom of the vertical pole 3 with the through hole 21 on the side wall of the positioning tube 2, and then insert the long bolt 22 into the through hole 21 to achieve a fixed connection between the vertical pole 3 and the positioning tube 2.

As shown in FIG. 2 and FIG. 3 , a square rod 6 is fixedly connected to the inner bottom wall of the slide groove 31 , a square groove 41 is opened at the bottom end of the screw rod 4 , and the square rod 6 penetrates into the square groove 41 and is slidably connected to the square groove 41 .

Through the limitation of the square rod 6 and the square groove 41 , the screw rod 4 can only move up and down in the slide groove 31 but cannot rotate.

As shown in Figures 1 to 3, the inner wall of the bottom end of the sleeve 5 is rotatably connected to the surface of the vertical rod 3 through a bearing, and the inner wall of the top end of the sleeve 5 is provided with a threaded groove 51, which is threadedly rotatably connected to the surface of the screw rod 4, and the outer wall of the sleeve 5 is fixedly connected with an external hexagonal nut 52.

Since the sleeve 5 is connected to the surface of the screw rod 4 by a threaded rotation, when the sleeve 5 is rotated, the sleeve 5 will drive the screw rod 4 to move upward or downward along the square rod 6. The height of the horizontal plate 7 or the vertical plate 8 is adjusted thereby.

As shown in Figures 1 and 2, the bracket assembly 9 includes a sleeve 91 slidably sleeved on the surface of the transverse plate 7 or the longitudinal plate 8, an arc-shaped support plate 92 is fixedly connected to the upper surface of the sleeve 91, and a locking bolt 93 penetrates through the bottom wall of the sleeve 91 and is threadedly connected.

The position of the arc-shaped support plate 92 can be changed by moving the sliding sleeve 91, so that the support plate 92 can be just aligned with the transverse or longitudinal steel bars, thereby supporting the steel bars with the support plate 92. After adjusting the position of the sliding sleeve 91, the locking bolt 93 can be tightened to fix the sliding sleeve 91.

As shown in Figures 1, 2 and 4, a connecting screw 10 matching the docking assembly 11 is fixed to the side wall of the base plate 1. The docking assembly 11 includes a connecting rod 111. The surfaces of both ends of the connecting rod 111 are slidably connected to internal threaded sleeves 112, and the internal threaded sleeves 112 are rotatably screwed to the surface of the connecting screw 10.

When connecting two adjacent base plates 1, the internal threaded sleeves 112 at both ends of the connecting rod 111 can be screwed onto the connecting screws 10 on the sides of the two base plates 1 respectively, thereby achieving a fixed connection of the base plates 1, so that multiple base plates 1 are combined into a frame body, thereby increasing the strength of the frame body.

As shown in Fig. 4, both ends of the connecting rod 111 are fixedly connected with end plates 113, and the end plates 113 are located inside the internal thread sleeve 112. The end plates 113 can prevent the internal thread sleeve 112 from being separated from the connecting rod 111.

Working principle: first insert the vertical rod 3 into the positioning tube 2 on the surface of each base plate 1, and then fix the vertical rod 3 with the long bolt 22. After the vertical rods 3 on the surface of the base plate 1 are assembled, connect the docking assembly 11 between two adjacent base plates 1. When connecting, screw the internal thread sleeve 112 on the surface of the connecting rod 111 to the surface of the connecting screw 10 on the side of the base plate 1, so that multiple base plates 1 and the structure on the surface of the base plate 1 are combined into a frame, and then the frame is placed under the horizontal and vertical steel bars of the fan, and then rotate the sleeve 5 at the top of each vertical rod 3, and use the sleeve 5 to drive the screw 4 to rise until the bracket assembly 9 on the surface of the horizontal plate 7 and the vertical plate 8 can contact the steel bar. It should be noted that during the process of raising the screw 4, the bracket assembly 9 on the surface of the horizontal plate 7 and the vertical plate 8 can be moved so that the arc-shaped support plate 92 on the bracket assembly 9 can just align with the steel bar. When the support plate 92 contacts the steel bar, tighten the locking bolt 93. When the support assembly is in use, it can be safely, quickly and accurately positioned and installed, thereby improving construction efficiency.
