It usually consists of two parts: a steel bar and a sleeve. The steel bar is used to support the concrete structure, and the sleeve is used to protect the steel bar from corrosion.

[0003] However, for existing steel bar sleeves, during use, the sizes of most steel bar sleeves are fixed and cannot be adjusted according to actual needs, which causes inconvenience to the work of staff. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an automatically adjustable size rolling billet sleeve to solve the problem that for existing steel bar sleeves, during use, the sizes of most steel bar sleeves are fixed and cannot be adjusted according to actual needs, which causes inconvenience to the work of staff.

[0005] To achieve the above purpose, an automatically adjustable size rolling billet sleeve is provided, which includes a connecting cylinder. A partition is fixedly connected to the middle of the connecting cylinder. A plurality of adjusting components for adjusting steel bars of different sizes are installed at positions near both ends of the inner wall of the connecting cylinder. The adjusting component includes a plurality of fixed cylinders installed on the inner wall of the connecting cylinder. A return spring is installed inside the fixed cylinder. One side of the return spring far from the bottom end of the fixed cylinder is fixedly connected to a fixed column. The fixed column slides inside the fixed cylinder. One end of the fixed column far from the fixed cylinder is fixedly connected to a contact plate.

[0006] As a further improvement of this technical solution, a plurality of through holes are opened at both ends of the inner and outer sides of the connecting cylinder, and the fixed cylinder slides inside the through holes.

[0007] As a further improvement of this technical solution, two thread grooves with opposite directions are opened in the middle of the outer side of the connecting cylinder, and a limiting cylinder is threadedly connected to the outside of the thread groove.

[0008] As a further improvement of this technical solution, a plurality of mounting holes are opened on both sides of the partition. A compression spring is fixedly connected to the bottom end inside the mounting hole. One end of the compression spring far from the inside of the mounting hole is fixedly connected to a short column that contacts the end of the steel bar.

[0009] As a further improvement of this technical solution, a limiting ring is fixedly connected inside the mounting hole, and the short column slides inside the limiting ring.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The automatic size-adjusting rolling billet sleeve realizes adaptive adjustment and fixation of steel bars of different sizes through the setting of the adjustment component. By rotating and twisting the limiting cylinder, the limiting cylinder can limit the fixing cylinder sliding inside the through hole. On the one hand, it further stabilizes the stability of the steel bar, and on the other hand, the limit can be released to facilitate the rotational adjustment of the steel bar. By arranging short columns on both sides of the partition plate, the ends of the steel bars inside the connecting cylinder are fixed. Description of the Drawings

[0020] See also Figures 1 - 3 As shown, an embodiment of the utility model provides an automatically adjustable size rolled billet sleeve, comprising a connecting tube 1, a partition plate 2 is fixedly connected to the middle of the connecting tube 1, a plurality of adjustment components for adjusting steel bars of different sizes are installed near the two ends of the inner wall of the connecting tube 1, the adjustment component comprises a plurality of fixed tubes 3 installed on the inner wall of the connecting tube 1, a reset spring 4 is installed inside the fixed tube 3, a fixed column 5 is fixedly connected to the side of the reset spring 4 away from the bottom end of the fixed tube 3, the fixed column 5 slides inside the fixed tube 3, a resistance plate 6 is fixedly connected to the end of the fixed column 5 away from the fixed tube 3, a plurality of through holes 7 are opened at both ends of the inner and outer sides of the connecting tube 1, the fixed tube 3 slides inside the through holes 7, two thread grooves 8 in opposite directions are opened in the middle of the outer side of the connecting tube 1, and the outer side of the thread groove 8 is threadedly connected to a limiting tube 9. Due to the setting of the adjustment component, the contact plate 6 that contacts the steel bar will drive the fixed column 5 to move toward the fixed tube 3 along with the steel bars of different sizes, and squeeze the reset spring 4. At this time, the size of the steel bar determines the size of the extrusion force on the reset spring 4, and drives multiple contact plates 6 to fix the outside of the steel bar at the same time in the form of elastic force, so that the stability of the steel bar is always maintained. When the steel bar needs to be replaced or rotated and adjusted, the limiting tube 9 is twisted in the opposite direction until the through hole 7 leaks out. At this time, the fixed tube 3 can slide inside the through hole 7, so that the reset spring 4 eliminates the limiting elastic force of the contact plate 6 on the steel bar, thereby realizing the replacement or adjustment of the steel bar.

[0021] See also Figure 4 As shown, a plurality of mounting holes 10 are provided on both sides of the partition 2, and a compression spring 11 is fixedly connected to the bottom end of the mounting hole 10, and a short column 12 in contact with the end of the steel bar is fixedly connected to the end of the compression spring 11 away from the mounting hole 10. As a further improvement of the present technical solution, a limiting ring 13 is fixedly connected to the mounting hole 10, and the short column 12 slides inside the limiting ring 13. Due to the arrangement of the compression spring 11 in the mounting hole 10, the inserted steel bar will drive the short column 12 in contact with the end of the steel bar to slide in the limiting ring 13 while moving toward the mounting hole 10, and squeeze the compression spring 11 in the mounting hole 10, so that the short column 12 on the side of the partition 2 that is not squeezed can surround the steel bar and limit it, further ensuring the stability of the steel bar.

[0022] Working principle: Before working, first twist a pair of limit cylinders 9 on the outside of the connecting cylinder 1 to move to both sides until the through hole 7 is fully covered, and then insert the two steel bars to be connected from both ends of the connecting cylinder 1 respectively. While inserting, due to the setting of the adjustment component, the contact plate 6 that contacts the steel bar will drive the fixed column 5 to move toward the fixed cylinder 3 along with steel bars of different sizes, and squeeze the reset spring 4. At this time, the size of the steel bar determines the size of the extrusion force on the reset spring 4, and drives multiple contact plates 6 in the form of elastic force to fix the outside of the steel bar at the same time, so that the stability of the steel bar is always maintained At the same time, the inserted steel bars will drive the short columns 12 on the side of the partition 2 to slide in the limiting ring 13 while moving toward the mounting hole 10, and squeeze the compression spring 11 inside the mounting hole 10, so that the un-extruded short columns 12 on the side of the partition 2 can surround the steel bars and limit them, further ensuring the stability of the steel bars. When the steel bars need to be replaced or rotated and adjusted, the limiting cylinder 9 is twisted in the opposite direction until it leaks out of the through hole 7. At this time, the fixed cylinder 3 can slide inside the through hole 7, so that the reset spring 4 eliminates the limiting elastic force of the resistance plate 6 on the steel bars, thereby realizing the replacement or adjustment of the steel bars.
