[0006] Preferably, one end of the fixed clamping shaft is fixedly connected to a turntable shaft, a threaded shaft is fixedly provided on the surface of the fixed clamping shaft, and the other end of the fixed clamping shaft is fixedly connected to a chuck block, and the chuck block is elliptical.

[0007] Preferably, a box door is fixedly provided at one end of the box frame body, and reinforcing support rods are fixedly connected to both ends of the frame.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. The utility model lifts and suspends the bottom frame and the box frame separately, which is beneficial to the lifting and loading and unloading of goods on the one hand, and is beneficial to the installation of the whole on the other hand. The box frame support plate and the box frame body can be supported and suspended as a whole in advance, and then the frame drives the frame to reverse to the lower end for installation, which saves a lot of labor.

[0015] 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.

[0016] See also Figure 1-4 The utility model provides a technical solution: a trailer suspension box frame, including a frame 1, a box frame support plate 2 is arranged on the upper end of the frame 1, a box frame body 4 is fixed to the upper end of the box frame support plate 2, the box frame body 4 and the box frame support plate 2 are fixedly provided with card slots 8 at the four corners of the bottom, the card slots 8 are elliptical, the four corners of the frame 1 are threadedly connected with fixed card shafts 6, the fixed card shafts 6 are snap-fitted with the card slots 8, and the lower end of the box frame support plate 2 is fixedly connected with a pneumatic suspension support foot 5.

[0017] In this embodiment, the fixed clamping shaft 6 is arranged to lock in the inside of the clamping slot 8 during the process of threaded rotation and lifting, so that the skeleton 1, the box frame support plate 2 and the box frame body 4 are locked together and fixedly connected. When the box frame body 4 needs to be lifted or lowered, the fixed clamping shaft 6 is threadedly rotated to align with the clamping slot 8, so that the box frame support plate 2 and the box frame body 4 as a whole can be separated from the skeleton 1. At this time, the turntable shaft 7 is arranged at the bottom for lifting and lowering, and the box frame support plate 2 and the box frame body 4 are supported and suspended. This design method separates the bottom skeleton and the box frame for lifting and hanging. On the one hand, it is beneficial to the lifting and unloading of goods, and on the other hand, it is beneficial to the installation of the whole. The box frame support plate 2 and the box frame body 4 can be supported and suspended as a whole in advance, and then the frame drives the skeleton 1 to reverse to the lower end for installation, which saves a lot of labor.

[0018] Specifically, one end of the fixed clamping shaft 6 is fixedly connected to the turntable shaft 7, a threaded shaft 9 is fixedly provided on the surface of the fixed clamping shaft 6, and the other end of the fixed clamping shaft 6 is fixedly connected to a chuck block 10, which is oval.

[0019] In this embodiment, the turntable shaft 7 is provided to facilitate the rotation and fixation of the clamping shaft 6, and the chuck block 10 is provided in an elliptical shape so as to be sleeved inside the clamping slot 8, so that when misaligned, it is convenient to clamp and fix.

[0020] Specifically, a box door 11 is fixedly provided at one end of the box frame body 4 , and reinforcing support rods 12 are fixedly connected to both ends of the frame 1 .

[0021] In this embodiment, the box door 11 is convenient for loading and unloading, and the supporting performance of the frame 1 can be enhanced by providing the reinforcing struts 12 .

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
