[0026] The transport rack includes a support frame, a crossbeam 1, a clamping mechanism, a supporting plate 4, a locking structure, a roller mechanism, and a buckle 5, wherein: the support frame is used to provide a folding function, the crossbeam 1 is used to support the back of the aluminum alloy doors and windows, the clamping mechanism is used to press the front of the aluminum alloy doors and windows and limit the sides of the aluminum alloy doors and windows, the supporting plate 4 is used to prevent the aluminum alloy doors and windows from sliding down, the roller mechanism is used to provide a moving function, the locking structure is used to lock the supporting plate 4 between adjacent transport racks, and the buckle 5 is used to clamp the roller mechanism between adjacent transport racks.

[0027] The support frame includes two groups, which can be placed side by side in the front-to-back direction. The two groups of support frames are connected by a crossbeam 1, which can be connected to the upper part of the support frame for installing a clamping mechanism, and can be sleeved with a buffer sleeve 10 on the outer side to avoid scratching the aluminum alloy doors and windows that are placed against it. The support frame is an A-shaped structure, and the top of the support frame can rotate with each other to provide a folding function. The support frame is unfolded into a tilted state, and the support frame is folded into an upright state. When the support frame is in a tilted state, the back of the aluminum alloy doors and windows can be tilted against the crossbeam 1, which is convenient for the staff to place the aluminum alloy doors and windows and is not easy to cause tipping.

It can be that several clamping mechanisms are installed side by side on the crossbeam 1. The swing rod 2 is swingably connected to the crossbeam 1 in the vertical direction. The two swing rods 2 are connected by the pressure rod 3. The pressure rod 3 is arranged toward the outside of the support frame. The outside may be sleeved with a buffer sleeve 10 to avoid scratching the aluminum alloy doors and windows against which they are placed. When the back of the aluminum alloy doors and windows is tilted against the crossbeam 1, the clamping mechanism swings downward, and the two sides of the aluminum alloy doors and windows are restricted between the two swing rods 2. The pressure rod 3 presses the front of the aluminum alloy doors and windows, and limits the front and back, left and right directions of the aluminum alloy doors and windows to avoid shaking during transportation.

[0029] The support plate 4 is located at the lower part of the support frame. The surface of the support plate 4 is provided with a downward groove, which is a U-shaped structure. The bottom of the aluminum alloy door and window is located in the support plate 4 to prevent the aluminum alloy door and window from sliding downward. The locking structure is located on the outer side of the support plate 4, which may include a locking block 12 and a locking groove 13. The locking block 12 is engaged with the locking groove 13 to play a locking role. The roller mechanism is located at the bottom of the support frame, which may include an axle 17 and a roller 18. The axle 17 is rotatably connected between the two groups of support frames. The axle 17 is rotatably connected with the roller 18 to provide a moving function.

First, place multiple transport racks side by side, and clamp the roller mechanisms between adjacent transport racks through the buckle 5 to achieve mutual connection. Next, push the roller mechanism to unfold the support frame to an upright state, and place the aluminum alloy doors and windows obliquely on each transport rack. The clamping mechanism presses and limits the aluminum alloy doors and windows. Finally, push the roller mechanism to close the support frame to an upright state, and the locking structures between adjacent transport racks are locked with each other to improve the connection stability, which is not easy to loosen and separate during transportation. The pressure rods 3 between adjacent transport racks conflict with each other to separate the aluminum alloy doors and windows, and the aluminum alloy doors and windows will not collide with each other.

[0031] The utility model is suitable for the transportation of aluminum alloy doors and windows. First, the support frame is unfolded to an inclined state, the back of the aluminum alloy doors and windows is tilted against the cross beam 1, and the bottom of the aluminum alloy doors and windows is located in the support plate 4 to prevent the aluminum alloy doors and windows from sliding down. Then, the clamping mechanism is swung downward, the two sides of the aluminum alloy doors and windows are restricted between the two swing rods 2, and the pressure rod 3 presses the front of the aluminum alloy doors and windows to prevent the aluminum alloy doors and windows from shaking during transportation. Finally, the support frame is folded into an upright state, and the aluminum alloy doors and windows are upright against the cross beam 1, which is conducive to reducing the occupied space and is convenient for transportation and storage. In addition, the roller mechanism can be clamped by the buckle 5 to connect multiple transport racks to improve the flexibility of use. After the support frame is adjusted to an upright state, the locking structures between adjacent transport racks are locked with each other, and the pressure rods 3 conflict with each other, thereby improving the connection stability and avoiding collisions between aluminum alloy doors and windows.

One end of the two connecting rods 7 is rotatably connected to the middle of the two columns 6 respectively, and the other ends of the two connecting rods 7 are sleeved on the outside of the rotating shaft and are rotatably connected through the rotating shaft. When the bottoms of the two columns 6 move away from each other, the rotation angle between the two connecting rods 7 increases, and the support frame is unfolded to an inclined state. The connecting rod 7 limits the movement stroke of the columns 6, thereby limiting the unfolding angle of the support frame. When the bottoms of the two columns 6 approach each other, the rotation angle between the two connecting rods 7 decreases, and the support frame is closed to an upright state.

[0034] In the present embodiment, preferably, a limit groove 8 is provided on the side of the connecting rod 7, and the rotating shaft is rotatably connected with a limit buckle 9, one end of the limit buckle 9 is sleeved on the outer side of the rotating shaft, and the other end of the limit buckle 9 is L-shaped and extends toward the limit groove 8, and the limit buckle 9 is clamped with the limit groove 8.

The beginning of the supporting plate 4 is open, and the end of the supporting plate 4 is installed with a buffer block 11, which can be made of an elastic material. When placing aluminum alloy doors and windows, the aluminum alloy doors and windows enter from the beginning of the supporting plate 4, and the bottom of the aluminum alloy doors and windows is located in the supporting plate 4. The pulley supports the aluminum alloy doors and windows, and by pushing the aluminum alloy doors and windows, it slides to the end of the supporting plate 4 until it touches the buffer block 11, which is beneficial for the staff to save physical strength and improve efficiency.
