[0012] The figure shows: 1-pressure plate body, 2-bolt hole, 3-stop step, 4-anti-slip teeth, 5-bolt, 6-subframe, 7-composite floor, 8-embedded steel parts. Detailed Implementation

[0013] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0014] like Figures 1 to 3 As shown, a refrigerated truck subframe pressure plate is provided. The pressure plate 1 is rectangular and has a bolt hole 2 in the middle. Two pressing working surfaces are provided on both sides of the bolt hole 2. Anti-slip teeth 4 are provided on both pressing working surfaces. A stop step 3 is provided on one of the pressing working surfaces, and the pressing working surface is recessed into the pressure plate 1. In this embodiment, the anti-slip teeth 4 can prevent the clamped subframe 6 and composite floor 7 from sliding; the stop step 3 restricts the position of the subframe 6 and prevents it from moving on the composite floor 7.

[0015] like Figure 5 As shown, the height of the stop step 3 is the same as the thickness of the wing plate of the subframe 6; this embodiment facilitates the pressure plate 1 to press the wing plate of the subframe 6.

[0016] like Figure 2 As shown, the bolt hole 2 is a slotted hole; In this implementation plan, the subframe 6 is a large component with large dimensional tolerances, and the bolt hole 2 is a waist-shaped hole, which facilitates the adjustment of the cumulative error of the parts during assembly.

[0017] like Figures 3 to 5As shown, the subframe 6 of the refrigerated truck is fixedly connected to the lower part of the composite floor 7 of the refrigerated truck through the pressure plate 1 mentioned above; wherein the stop step 3 of the pressure plate 1 and the stop of the wing plate of the subframe 6 in contact with the composite floor 7 are pressed against each other, and the anti-slip teeth 4 of its pressing working surface are pressed on the wing plate of the subframe 6, and the anti-slip teeth 4 of its corresponding other pressing working surface are pressed on the composite floor 7. In this embodiment, the subframe 6 of the refrigerated truck is fixedly connected to the frame of the refrigerated truck, and the composite floor 7 of the refrigerated truck is fixedly connected to the subframe 6 of the refrigerated truck; the subframe 6 of the refrigerated truck is fixedly connected to the lower part of the composite floor 7 of the refrigerated truck by a pressure plate 1.

[0018] like Figure 5 As shown, the pressure plate 1 is threadedly connected to the embedded steel part 8 by bolts 5 passing through bolt holes 2, and the embedded steel part 8 is set in the composite floor 7; In this embodiment, multiple embedded steel parts 8 are provided in the composite floor 7. The function of the embedded steel parts 8 is to allow the bolts 5 to pass through the bolt holes 2 of the pressure plate 1 and connect with its threads, so as to provide clamping force to the pressure plate 1.

[0019] like Figure 4 As shown, the subframe 6 is a Z-shaped lightweight frame; In this implementation scheme, the subframe 6 is a Z-shaped lightweight frame, which facilitates the clamping and installation of the pressure plate 1.

[0020] The specific working principle of this utility model is as follows: First, securely connect the subframe 6 to the frame of the refrigerated truck; Then place the composite floor 7 of the refrigerated truck on the subframe 6 of the refrigerated truck and adjust the relative assembly position. Finally, at the corresponding position, the bolt 5 is threaded through the bolt hole 2 of the pressure plate 1 and connected to the embedded steel part 8. During the connection process, the position of the pressure plate 1 is adjusted through the waist-shaped hole of the bolt hole 2 so that the stop step 3 of the pressure plate 1 and the stop of the subframe 6 wing plate are pressed together. Then the bolt 5 is tightened so that the anti-slip teeth 4 on the two pressing working surfaces of the pressure plate 1 are pressed onto the subframe 6 wing plate and the composite floor 7 respectively. The entire installation is completed.
