For example, "connected" can mean fixed connection, welding, riveting, bonding, etc., or detachable connection, threaded connection, key connection, pin connection, etc., or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0025] like Figure 1-6As shown, the utility model proposes a truck compartment guardrail structure, including a guardrail frame, the guardrail frame includes a lower cross guardrail 4 and an upper cross guardrail 2, both sides of the upper end surface of the lower cross guardrail 4 are respectively connected to the vertical frame 5 through a connecting component, the upper ends of the vertical frames 5 on both sides are connected to the upper cross guardrail 2, the upper cross guardrail 2 is hinged to the vertical frame 5 on one side, and the upper cross guardrail 2 is connected to the vertical frame 5 on the other side through a fixing component, the lower end surface of the upper cross guardrail 2 is equidistantly provided with a third limiting hole 12, the upper end surface of the lower cross guardrail 4 is provided with a plurality of second limiting holes 11 adapted to the third limiting holes 12, and the second limiting holes 11 adapted to the upper and lower sides are connected to the third limiting holes 12 through a guardrail component.

[0026] In the present invention, when the guardrail assembly is damaged and needs to be replaced, the fixing assembly is first opened, the connection between the upper horizontal guardrail 2 and the vertical frame 5 is cancelled, and then the upper horizontal guardrail 2 is rotated to pull the guardrail assembly out of the second limiting hole 11 on the lower horizontal guardrail 4, and then the usable guardrail assembly is inserted into the inside of the second limiting hole 11, and then the upper horizontal guardrail 2 is rotated in the opposite direction so that the top of the guardrail assembly is inserted into the inside of the third limiting hole 12, and then the fixing assembly is adjusted to fix the vertical frame 5 to the upper horizontal guardrail 2, so as to facilitate the replacement of the guardrail assembly; and through the connecting assembly, the vertical frame 5 can be removed or installed from the lower horizontal guardrail 4, and can be replaced when the vertical frame 5 is damaged, and can be removed for transportation.

[0027] In an optional embodiment, the connecting assembly includes a second limit block 14 and a fixing bolt 1, a first limit hole 10 is opened on both sides of the upper end surface of the lower cross railing 4, the second limit block 14 is arranged at the bottom of the vertical frame 5, the second limit block 14 is inserted into the inside of the first limit hole 10, the fixing bolt 1 passes through the outer end surface of the lower cross railing 4 and extends to the inside of the second limit block 14, and the fixing bolt 1 is threadedly connected to the second limit block 14.

[0028] It should be noted that, by driving the fixing bolt 1 to rotate, the fixing bolt 1 is pulled out. At this time, the second limit block 14 at the bottom of the vertical frame 5 can be pulled out from the inside of the first limit hole 10, so that the vertical frame 5 and the lower cross railing 4 can be separated; when the vertical frame 5 needs to be removed from the lower cross railing 4, the second limit block 14 at the bottom of the vertical frame 5 is inserted into the inside of the first limit hole 10, and then the fixing bolt 1 is driven to rotate in the opposite direction, so that the fixing bolt 1 is connected with the inside of the second limit block 14, thereby fixing the second limit block 14 inside the first limit hole 10, so that the lower cross railing 4 and the vertical frame 5 are connected.

[0029] In an optional embodiment, the first limiting hole 10 is rectangular, and the size of the second limiting block 14 is adapted to the first limiting hole 10 .

[0030] It should be noted that, because the first limiting hole 10 is rectangular, when the second limiting block 14 at the bottom of the vertical frame 5 is inserted into the first limiting hole 10 , the vertical frame 5 can be limited to prevent the vertical frame 5 from rotating.

[0031] In an optional embodiment, the fixing assembly includes a groove block 6, a limiting ring 7, a connecting block 8 and a rotating handle 9. The groove block 6 is arranged on the upper horizontal railing 2, the connecting block 8 is arranged on the vertical frame 5 on the other side, the groove block 6 is arranged directly above the connecting block 8, the rotating handle 9 is rotatably connected to the middle of the connecting block 8, one end of the limiting ring 7 is rotatably connected to the middle of the rotating handle 9, and the other end of the limiting ring 7 is connected to the groove end of the groove block 6, and the groove end of the groove block 6 faces upward.

[0032] It should be noted that when the damaged guardrail assembly needs to be replaced, first turn the handle 9 upwards. At this time, the handle 9 can rotate inside the connecting block 8, and the handle 9 can drive the limit ring 7 to move. At this time, the limit ring 7 can be disconnected from the groove block 6, so that the upper cross guardrail 2 can be limited and driven to rotate. Then replace the guardrail assembly, insert the replaced guardrail assembly into the second limiting hole 11, and then rotate the upper cross guardrail 2 in the opposite direction. Then, clamp the limiting ring 7 in the groove of the groove block 6, and rotate the handle 9 in the opposite direction, so that the upper cross guardrail 2 can be limited and fixed.

[0033] In an optional embodiment, the guardrail assembly includes a truck compartment guardrail tube 3 and a first limit block 13. The upper and lower sides of the truck compartment guardrail tube 3 are respectively connected to the first limit block 13. The first limit block 13 on one side of the truck compartment guardrail tube 3 is inserted into the third limit hole 12, and the first limit block 13 on the other side of the truck compartment guardrail tube 3 is inserted into the second limit hole 11. The third limit hole 12 is the same size as the second limit hole 11, and the size of the first limit block 13 is adapted to the third limit hole 12 and the second limit hole 11.

[0034] It should be noted that when the truck compartment guardrail tube 3 is inserted into the second limiting hole 11, since the first limiting blocks 13 at both ends of the truck compartment guardrail tube 3 are the same and the third limiting hole 12 is the same size as the second limiting hole 11, when installing the truck compartment guardrail tube 3, it is only necessary to ensure that the truck compartment guardrail tube 3 is in a vertical state before installation.
