Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

The purpose of the utility model is to improve the existing cable reel adjustment status to solve the technical problem of inconvenient adjustment and high cost.

As shown in FIG. 1 , an adjustable cable reel 50 bracket of the present invention includes a support frame 10 , an adjusting screw 20 , a driving handle 30 , a main shaft 40 and a cable reel 50 .

There are two support frames 10 and they are arranged separately. There are two adjustment screw rods 20 and they are erected. The two adjustment screw rods 20 are threadedly connected with the corresponding support frames 10 respectively. Adjusting screw rod 20, the main shaft 40 is horizontally arranged between the two support frames 10 and the ends are respectively connected with the two adjusting screw rods 20. The material of the main shaft 40 can be selected from the steel pipe on the construction site. When the main shaft 40 rotates, the driving handle 30 can drive the adjusting screw 20 to rotate, and the main shaft 40 can move vertically along with the adjusting screw 20 .

During work, by turning the driving handle 30, the adjusting screw 20 can be rotated relative to the support frame 10. At the same time, the adjusting screw 20 moves vertically relative to the support frame 10, and the main shaft 40 moves synchronously with the two adjusting screws 20, thereby realizing the cable reel. 50's up and down.

On the basis of the above structure, the utility model further improves and refines it.

As shown in FIGS. 1 to 3 , a fixed collar 60 is movable at the bottom of each adjusting screw 20 and the fixed collar 60 can rotate relative to the adjusting screw 20 . The ends of the main shaft 40 all extend into the fixed collar 60 .

By setting the fixed collar 60, the two ends of the main shaft 40 can respectively extend into the two fixed collars 60, thereby facilitating the disassembly and assembly of the main shaft 40 and the adjusting screw 20, and the fixed collar 60 can rotate relative to the adjusting screw 20 to avoid fixing The ferrule 60 rotates synchronously with the adjusting screw 20 to ensure the normal adjustment of the height of the main shaft 40 .

As shown in Fig. 3, a movable shaft 21 is threaded axially inside the adjusting screw 20, and the upper end of the movable shaft 21 is fixedly connected with a limit block 22, and the limit block 22 is against the upper end of the adjusting screw 20, and the fixed collar 60 is fixedly connected with movable shaft 21 lower ends.

The fixed collar 60 is fixedly connected with the movable circle, and the movable shaft 21 rotates in the adjusting screw 20, thereby realizing the rotation of the fixed collar 60 relative to the adjusting screw 20, and the limit block 22 abuts against the upper end of the adjusting screw 20 to fix the movable shaft. 21 to prevent the movable shaft 21 from moving downward under the action of the main shaft 40 .

As shown in Figure 3, the upper and lower ends of the adjusting screw 20 are fixed with positioning bearings 23, the movable shaft 21 passes through the two bearings and is connected with the two bearings, the limiting block 22 and the fixed ring 60 respectively On the corresponding locating bearing 23 .

The setting of the positioning bearing 23 plays a positioning role on the upper and lower ends of the movable shaft 21, avoids the lateral movement of the movable shaft 21, and improves the stability of the movable shaft 21. At the same time, the positioning bearing 23 can improve the flexibility and smoothness, reduces the resistance when the movable shaft 21 rotates, and avoids the influence of the rotation of the adjusting screw 20 on the main shaft 40 to the greatest extent. The positioning effect of 21 is better.

As shown in Fig. 1 and Fig. 2, the support frame 10 includes an upper fixed plate 11, a lower fixed plate 12 and a support rod 13, the upper fixed plate 11 is a square plate and is arranged horizontally, and the adjusting screw rod 20 and the upper fixed plate 11 Threaded connection, the lower fixed plate 12 is located below the upper fixed plate 11 and is spaced parallel with the upper fixed plate 11, the lower fixed plate 12 is also a square plate, and there are four support rods 13 and the four support rods 13 are respectively located on the four corners And the two ends of the support rod 13 are fixedly connected with the upper fixing plate 11 and the lower fixing plate 12 respectively.

The upper fixed plate 11 is separated from the lower fixed plate 12, and the adjusting screw rod 20 is threadedly connected with the upper fixed plate 11. Therefore, the lower end of the adjusting screw rod 20 stretches between the upper fixed plate 11 and the lower fixed plate 12. Straight movement improves the effective space.

Further, the projected area of the lower fixed plate 12 is twice the projected area of the lower fixed plate 12, that is to say, the area of the lower fixed plate 12 is greater than the area of the upper fixed plate 11, so that the lower fixed plate 12 and the The contact area of the ground improves the stability of the whole supporting frame 10 .

The utility model can adopt the following steps to carry out when in use:

S1: Place two support frames 10 at a suitable position on the construction site;

S2: Roll the cable reel 50 to the side of the bracket, pass the main shaft 40 through the center of the cable reel 50, lift the main shaft 40 and the cable reel 50 at the same time, and insert the two ends of the main shaft 40 into the two support frames 10 for fixing ferrule 60;

S3: Rotate the driving handle 30 of the support frame 10 to adjust the height of the adjusting screw 20 and lift the cable reel 50 to a proper height.

The specific embodiments described herein are only examples to illustrate the spirit of the present invention.
