[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figures 1 to 4In this embodiment, the truck body-in-white includes a rear panel, and a plurality of evenly arranged mounting holes are provided on the rear panel, and the mounting holes can be circular or square. The expansion device connector for the truck body-in-white of the embodiment of the present invention includes a connecting shaft 1, which can pass through the mounting hole, and a mounting plate 2 is provided at one end of the connecting shaft 1, and four receiving grooves 11 extending along the axial direction of the connecting shaft 1 are provided on the circumference of the connecting shaft 1, and the four receiving grooves 11 are evenly distributed on the circumference of the connecting shaft 1, and a fixing rod 3 is hinged at the end of the receiving groove 11 away from the mounting plate 2, and a connecting rod 4 is hinged in the receiving groove 11 between the fixing rod 3 and the mounting plate 2, and the connecting rod 4 is connected to a blade-shaped fixing plate 5.

[0021] When it is necessary to install the expansion device, first fold the connecting rod 4 together with the fixing plate 5, then fold the fixing rod 3, then pass the connecting shaft 1 through the installation hole, and finally unfold the fixing rod 3 and the fixing plate 5. The unfolded fixing rod 3 and the fixing plate 5 are respectively located on both sides of the rear panel, so that the fixing rod 3 and the fixing plate 5 tightly clamp the rear panel.

[0022] The mounting plate 2 is provided with a plurality of screw holes 21 for fixing the expansion device. The number of the screw holes 21 is, for example, four. The shape of the mounting plate 2 is, for example, square. The four screw holes 21 are distributed at the four corners of the mounting plate 2 .

[0023] See also Figure 5 and Figure 6 In order to fix the position of the fixed rod 3 after being unfolded, the two fixed rods 3 arranged opposite to each other are provided with a locking assembly, which includes a roller 61 and a spring 62. The spring 62 is arranged outside the end of the receiving groove 11 away from the mounting plate 2. The roller 61 is located in the receiving groove 11 and is rotatably connected to the receiving groove 11 and is slidably connected to the receiving groove 11. It can slide within a predetermined distance and can rotate itself. The roller 61 has a notch in the radial direction. When the fixed rod 3 rotates to be perpendicular to the connecting shaft 1, the spring 62 stretches and pushes the roller 61. The roller 61 is located on the side of the fixed rod 3 facing the fixing plate 5 and the notch of the roller 61 is adjacent to the fixed rod 3 and facing downward. When the fixed rod 3 rotates to be parallel to the connecting shaft 1, the spring 62 is compressed by the roller 61. The roller 61 is located on the side of the fixed rod 3 away from the fixing plate 5, and the end of the fixed rod 3 is engaged with the notch of the roller 61. The spring 62 can be buried inside the connecting shaft 1 or partially exposed outside the connecting shaft 1.

[0024] The notch of the roller 61 is fan-shaped, as shown in FIG. Figure 6 As shown, the notch of the roller 61 occupies 1 / 4 of the area of ​​the roller 61 in the axial direction of the roller 61 .

[0025] See also Figure 7The other two fixing rods 3 arranged opposite to each other are provided with a buckle 7 on the side away from the fixing plate 5. The buckle 7 is arranged on the outer side of the end of the accommodating groove 11 away from the mounting plate 2. One end of the buckle 7 is hinged to the connecting shaft 1, and the other end can be lifted to resist and support the fixing rod 3.

[0026] Participate again Figures 1 to 4 In this embodiment, a groove 31 is provided at the end of one of the two adjacent fixing rods 3, and a protrusion 32 is provided at the end of the other fixing rod 3, and the protrusion 32 can be fitted into the groove 31. Since some expansion devices are very heavy, they are prone to displacement in the vertical direction, causing deformation of the rear panel. Through the groove 31 and the protrusion 32, the two adjacent expansion device connectors can fix the fixing rods 3 of the two, thereby preventing the deformation of the rear panel caused by displacement in the vertical direction.

[0027] See also Figure 8 In order to accommodate larger expansion devices, in this embodiment, the expansion device connector also includes an extension shaft 8, the connecting shaft 1 is a hollow structure and has an internal thread, the extension shaft 8 can be threadedly connected to the connecting shaft 1, and the mounting plate 2 is arranged at the end of the extension shaft 8.

[0028] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
