Carriage structure

Abstract

This invention relates to a carriage structure, comprising: a main body having an opening, a first groove, and two notches; two first slide rails being accommodated in each of the first grooves, each first slide rail having a sliding portion; two second slide rails being slidably disposed in the sliding portions, each second slide rail having a first pivot portion at each end; a door system covering and closing the opening, and the door system being able to be opened laterally from the opening, the door system having two second grooves, two rod grooves, and two receiving spaces; two pivots being pivotally disposed in each of the rod grooves, the pivots being rotatable within the rod grooves, each pivot having a handle, the handle being accommodated in or unscrewed from the second grooves, and the pivot having two extension portions and a second pivot portion.

Claims

1. A carriage structure, comprising: The system comprises: a main body having an opening, with a first groove on each of the upper and lower sides of the opening, and each first groove having two notches; two first slide rails, each of which is accommodated in each of the first grooves and has a sliding portion; and two second slide rails, each of which slides alongside each of the first slide rails, the length of the second slide rail being less than the length of the first slide rail, the second slide rail sliding within the sliding portion, the second slide rail being movable on the sliding portion, and each of the two ends of the second slide rail having a first pivot portion protruding outside the sliding portion. A door body, the door system covering the opening and closing the opening, and the door system being able to be opened laterally from the opening, the door system having two second grooves, the door system having two rod receiving grooves, each rod receiving groove communicating with each of the second grooves, the rod receiving grooves penetrating the door body vertically, the door system having two receiving spaces, the receiving spaces communicating with the two rod receiving grooves, the two receiving spaces being respectively located at the upper and lower ends of the door body, the receiving spaces being aligned with the first groove; Two pivot rods, each pivot rod is pivotally mounted in each of the receiving rod grooves, and the pivot rod can rotate within the receiving rod grooves. Each pivot rod is provided with a handle, which can be accommodated in the second groove or unscrewed out of the second groove. The position of the handle is aligned with the position of the second groove. Each pivot rod is provided with two extensions, which are respectively located at the upper and lower ends of the pivot rod. The extensions can be accommodated in the notch, the first groove, and the receiving space. Each extension is provided with a second pivot, which is pivotally mounted to the first pivot.

2. The carriage structure as described in claim 1, wherein, The body is located in the cargo box at the rear of a truck or in the cargo box of various vehicles. The opening is slightly rectangular and located on one side of the body. The two first grooves are symmetrical to the opening. The first grooves are elongated and extend in the same direction as the length of the body. The two notches are spaced apart and the upper and lower notches are respectively aligned.

3. The carriage structure as described in claim 1, wherein, The first slide rail is elongated, and the sliding part extends in the same direction as the first slide rail. The sliding part is slightly concave.

4. The carriage structure as described in claim 1, wherein, The first pivot is shaped like a through hole.

5. The carriage structure as described in claim 1, wherein, The two second grooves are spaced apart by a distance. The second grooves are slightly rectangular in shape and are non-through grooves. The rod groove is circular in shape and extends in the same direction as the long side of the door.

6. The carriage structure as described in claim 1, wherein, The pivot is in the shape of a long rod, the extension is in the shape of a plate, and the second pivot is in the shape of a through hole.

7. The carriage structure as described in claim 1, wherein, The door system covers the opening. When the handle is pulled out of the second groove, the pivot rotates at the receiving groove. The extension is simultaneously driven to rotate out of the notch around the first pivot and the second pivot. At this time, the door body is a distance away from the opening system. If the handle is pushed continuously, the pivot can drive the door body and the second slide rail to move laterally in a straight line on the sliding part, so that the door body moves laterally relative to the opening and the opening is in an open state.

8. The carriage structure as described in claim 1, wherein, The device has a plurality of pins, each pin being assembled at each of the first pivot and each of the second pivot, such that the extension is pivotally connected to the second slide rail, and the number of pins is four.

9. The carriage structure as described in claim 1, wherein, Two lock sets are provided, each lock set is disposed in each of the second grooves. The lock sets allow the handle to be accommodated in the second grooves and prevent the handle from coming out of the second grooves. When the lock sets are released, the handle can be rotated out from the second grooves.
