DETAILED DESCRIPTION

[0017] 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 in 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.

[0018] See also Figure 1-2 The embodiment of the utility model provides a technical solution: a combined U-shaped bolt structure for installing a car cargo box, comprising a U-shaped bolt 1, a supporting device 2, a frame longitudinal beam 3, an adhesive tape 4, a cargo box longitudinal beam 5 and a pressing plate 6, wherein the supporting device 2 is sleeved on the right end of the U-shaped bolt 1 and is located at the right end of the inner side of the U-shaped bolt 1, the frame longitudinal beam 3, the adhesive tape 4 and the cargo box longitudinal beam 5 are sequentially installed in the U-shaped bolt 1, the pressing plate 6 is sleeved on the top of the U-shaped bolt 1, and locking nuts 7 are fixed on both the left and right ends of the top of the U-shaped bolt 1;

[0019] To solve the problem, a group of steel ball adjustment holes 13 are arranged in a row and equidistantly at the right end of the U-shaped bolt 1;

[0020] Furthermore, the support device 2 is a cylindrical structure, and the support device 2 is located in the opening of the frame longitudinal beam 3. A group of screws 10 are arranged on the left side of the support device 2 in a column-like and equidistant manner. A spring 11 is sleeved on the outer side of the screw 10, and the spring 11 is located in the support device 2. A steel ball 12 is pressed in the spring 11. When in use, the support device 2 is fixed or rotated. The steel ball adjustment hole 13 on the support device 2 is for installing the spring 11 to press the steel ball 12. The spring 11 is pressed into the hole of the support device 2 with the screw 10. When the support device 2 is rotated to the point where the steel ball 12 is aligned with the steel ball adjustment hole 13 of the U-bolt 1, the steel ball 12 automatically locks the support device 2 under the pressure of the spring 11. At this time, the support device 2 is in a locked state in the rotation direction; when the support device 2 is rotated again with force, when the force is large enough to overcome the pressure of the steel ball spring, the steel ball 12 withdraws from the steel ball adjustment hole 13 of the U-bolt 1, and the support device 2 returns to a rotatable state.

[0021] Differently, a group of sliding cylinders 8 distributed in a column-like and equidistant manner are provided on the right side of the support device 2. The sliding cylinder 8 and the support device 2 are a through structure. Elastic retaining rings 9 are provided at the upper and lower ends of the sliding cylinder 8. The sliding cylinder 8 is used to facilitate the support device 2 to be installed on the U-shaped bolt 1 by means of a socket connection, and the elastic retaining ring 9 is used to fix the support device 2 on the U-shaped bolt 1.

[0022] Effectively, the top and the bottom of the support device 2 are both threadedly mounted with adjustment bolts 14, and the staff can adjust the height by adjusting the adjustment bolts 14, which further facilitates the support device 2 to fully match the frame width.

[0023] Working principle: During operation, the staff can adjust the height by adjusting the adjusting bolt 14, so as to further facilitate the support device 2 to fully match the frame width. When the support device 2 is fixed or rotated, the steel ball adjustment hole 13 on the support device 2 is for installing the spring 11 to compress the steel ball 12. The spring 11 is pressed into the hole of the support device 2 with a screw 10. When the support device 2 is rotated to the point where the steel ball 12 is aligned with the steel ball adjustment hole 13 of the U-bolt 1, the steel ball 12 automatically locks the support device 2 under the pressure of the spring 11. At this time, the support device 2 is in a locked state in the rotation direction. When the support device 2 is rotated again with force, when the force is large enough to overcome the pressure of the steel ball spring, the steel ball 12 withdraws from the steel ball adjustment hole 13 of the U-bolt 1, and the support device 2 returns to a rotatable state.

[0024] The utility model includes 1. U-shaped bolt; 2. supporting device; 3. frame longitudinal beam; 4. tape; 5. cargo box longitudinal beam; 6. pressure plate; 7. locking nut; 8. sliding cylinder; 9. elastic retaining ring; 10. screw; 11. spring; 12. steel ball; 13. steel ball adjustment hole; 14. adjusting bolt. All the components are universal standard parts or components known to technical personnel in this field, and their structures and principles can be known to technical personnel in this field through technical manuals or through conventional experimental methods. The utility model solves the problem that when the existing traditional U-shaped bolts are used to install the cargo box, the open end of the frame longitudinal beam will be seriously deformed when tightening due to the U-shaped cross-section of the frame longitudinal beam, which affects the strength and service life of the frame, and is not easy to lock the cargo box, which brings safety hazards. The utility model can prevent the frame from being deformed when installing and tightening the cargo box through the combination of the above-mentioned components, and can firmly lock the cargo box, thereby improving the safety of the entire vehicle.
