[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 As shown, this utility model provides a double-door four-fold cover, including a frame body 1. One end of the frame body 1 is provided with a first door 2, a middle plate 16 and a second door 3 respectively. The other end of the frame body 1 is provided with a connecting plate 4, a first flip door 5 and a second flip door 6 respectively. At the same time, the first door 2 and the second door 3 are provided with hinge components 15 between them and the middle plate 16. A second positioning block 12 is fixedly connected to the back beam of the frame body 1, and the second positioning block 12 is placed on the back of the first door 2 and the second door 3 respectively. A first positioning block 11 is provided at one corner of the back of the first door 2 and the back corner of the second door 3. The first positioning block 11 and the second positioning block 12 are rotatably connected to the two ends of the telescopic rod 10 respectively. At the same time, a locking component 9 is installed between the first door 2 and the second door 3 and the side beam of the frame body 1. A support and tensioning component 8 is provided below the first flip door 5 and the second flip door 6, and the two ends of the support and tensioning component 8 are locked inside the back of the two side beams of the frame body 1.

[0023] In this embodiment, a connecting plate 4 is fixedly connected in the middle of the frame body 1, and a folding component 7 is installed between one side of the connecting plate 4 and one side of the first folding door 5. At the same time, the two end faces of the first folding door 5 are tightly fitted to the side wall of the frame body 1.

[0024] Furthermore, a folding assembly 7 is installed between the other side of the first folding door 5 and one side of the second folding door 6, and the end faces of the other three sides of the second folding door 6 are tightly fitted to the side wall of the frame body 1.

[0025] A folding component 7 is provided between the connecting plate 4 and the first folding door 5, and a folding component 7 is provided between the first folding door 5 and the second folding door 6. The second folding door 6 can be folded down onto the first folding door 5 on its own. When the first folding door 5 and the second folding door 6 are folded down at the same time, the folding component 7 between the first folding door 5 and the second folding door 6 can be raised up, and the second folding door 6 can also be folded behind the first folding door 5 for support.

[0026] In this embodiment, both ends of the support tensioning assembly 8 are provided with press-fit fastening parts 801, and the press-fit fastening parts 801 are snapped into the beams on both sides of the frame body 1.

[0027] After the support and tensioning components 8 are installed behind the first flip door 5 and the second flip door 6, they can be supported. Since the springs are provided in the pressing fastening parts 801 at both ends of the support and tensioning components 8, the first flip door 5 and the second flip door 6 can be opened directly when they are flipped. After pressing, the pressing fastening parts 801 are pressed into the beams on both sides of the frame body 1 for fixation.

[0028] In this embodiment, a limiting pin 901 is provided on one side of the back of the locking assembly 9, and the limiting pin 901 is respectively placed on the back of the first door 2 and the second door 3. At the same time, the limiting pin 901 is fixedly connected to the two beams on both sides of the frame body 1.

[0029] By directly pressing the hole on the front of the latch assembly 9 from the outside, the limiting pin 901 on the back can be pulled, and the limiting pin 901 will disengage from the beams on both sides of the frame body 1, so that the first door 2 and the second door 3 can be opened.

[0030] In this embodiment, a limiting block 17 and a fixing seat 18 are fixedly connected to both sides of the back of the frame body 1, and one end of the limiting block 17 is rotatably connected to the support rod 13.

[0031] Furthermore, the fixed base 18 has an opening on one side, and the fixed connecting support rod 13 is inserted into the opening.

[0032] The support rod 13 on the back of the frame body 1 is rotatably connected to the limiting block 17. After the first flip door 5 and the second flip door 6 are folded over, the support rod 13 can be used to support the lower end of the support tensioning component 8, so that the first flip door 5 and the second flip door 6 can be stable. At the same time, when not in use, the support rod 13 is locked in the fixed seat 18 to prevent it from shaking back and forth.

[0033] In this embodiment, support legs 14 are fixedly connected to the four corners of the back of the frame body 1. The support legs 14 provided at the four corners of the frame body 1 are inserted into the four corners of the pickup truck bed, so that the entire structure is stable in the truck bed.

[0034] Working principle:

[0035] A first door 2, a middle plate 16, and a second door 3 are respectively provided on one side of the main frame 1. Hinges 15 are provided between the first door 2, the second door 3, and the middle plate 16, so that the first door 2 and the second door 3 can be opened towards the middle plate 16. A telescopic rod 10 is provided between the second positioning block 12 on the back beam of the main frame 1 and the first positioning block 11 at one corner of the back of the first door 2 and at one corner of the back of the second door 3. At the same time, a locking assembly 9 is provided between the first door 2, the second door 3, and the main frame 1. Then, by inserting the latch into the hole on the front of the latch assembly 9, the limiting pin 901 on the back of the latch assembly 9 is disengaged from the two side beams of the frame body 1, and the first door 2 and the second door 3 can be opened. At the same time, the telescopic rod 10 not only supports the first door 2 and the second door 3, but also prevents the first door 2 and the second door 3 from being opened too wide. After the entire structure is placed in the pickup truck bed, the first door 2 and the second door 3 are on the side closer to the driver's cab. This way, the opening method makes it convenient to take out items in the bed without having to flip the entire structure open to get them.

[0036] In addition, a support and tensioning assembly 8 is provided in the middle of the back of the first flip door 5 and the second flip door 6. The pressing fastening parts 801 at both ends of the support and tensioning assembly 8 are fixed to the two side beams of the frame body 1. This can increase the support force of the first flip door 5 and the second flip door 6. Since the pressing fastening part 801 has a spring inside, when the first flip door 5 and the second flip door 6 are flipped, the internal spring is compressed and they can be pulled open directly. When the first flip door 5 and the second flip door 6 are closed, the internal spring is also compressed and they can be pressed down directly.
