[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] See Figures 1-6 As shown, this utility model provides a lifting device for the roof of a truck, including a truck bed 1, a roof 2 above the truck bed 1, hollow rods 4 fixedly connected to the four corners of the truck bed 1, and movable rods 5 inserted and sleeved with the hollow rods 4 fixedly connected to the four corners of the roof 2. One of the hollow rods 4 is provided with a linkage structure for simultaneously driving the four movable rods 5 to rise and fall at the same time.

[0030] The four hollow rods 4 are rod body one 401 and rod body two 402 located on the rear side of the vehicle, and rod body three 403 and rod body four 404 located on the front side of the vehicle. The four movable rods 5 are insert rod one 501 and insert rod two 502 located on the rear side of the vehicle, and insert rod three 503 and insert rod four 504 located on the front side of the vehicle.

[0031] As an optional implementation, the linkage structure includes a rope winding structure 6 mounted on rod 1 401 to drive the insertion rod 1 501 to move up and down; a pull rope structure 7 between rod 1 401 and rod 2 402 to drive the insertion rod 2 502 to move up and down with the movable part of the rope winding structure 6; a pull rope structure 8 between rod 1 401 and rod 3 403 to drive the insertion rod 3 503 to move up and down with the movable part of the rope winding structure 6; and a pull rope structure 9 between rod 3 403 and rod 404 to drive the insertion rod 4 504 to move up and down with the insertion rod 3 503. Through the rope winding structure 6, pull rope structure 7, and pull rope structure 8... The linkage between the three-wire structure 9 and the first-wire structure 501 allows the second-wire structure 502, the third-wire structure 503, and the fourth-wire structure 504 to rise stably together when the first-wire structure 501 rises. At the same time, when the winding wheel 604 unwinds, the roof panel 2 and the four movable rods 5 automatically fall under their own weight. It is worth mentioning that a resistance pad can be set between the contact surfaces of the movable rods 5 and the hollow rods 4 to provide resistance to the movement of the movable rods 5 when they rise and fall, thus preventing the roof panel 2 from shaking and making noise due to bumps and vibrations during vehicle operation. In addition, counterweights can be set on the roof panel 2 and the four movable rods 5 to further prevent the roof panel 2 from shaking and making noise.

[0032] Reference Figure 3 As shown, the rope winding structure 6 includes a winding wheel 604 rotatably connected to the lower side wall of the rod 401. A connecting block 601 is fixedly connected to the bottom side wall of the insert rod 501, and the rod 401 has a movable groove for the connecting block 601 to move up and down. A guide wheel 603 is rotatably connected to the upper side wall of the rod 401. A connecting rope 602 is fixedly connected to the connecting block 601. The other end of the connecting rope 602 abuts against the upper side of the guide wheel 603, passes around it, and is fixedly connected to the winding wheel 604. 01 is provided with a plug-in assembly 3 for fixing the rotation position of the take-up reel 604. A linkage block 605 is fixedly connected to the connecting rope 602 located above the take-up reel 604. By rotating the take-up reel 604, the connecting rope 602 can be driven to wind up on its surface. When the rope on one side of the guide wheel 603 moves down, the rope on the other side of the guide wheel 603 moves up. That is, the other end of the connecting rope 602 drives the insert rod 501 to rise. Through the design of the linkage block 605, the insert rod 502 and the insert rod 503 can be driven to rise together at the same time.

[0033] Reference Figure 6As shown, the insertion assembly 3 includes a pin hole 303 on the side wall of the rod body 401, into which a pin 302 is inserted. Several pin sleeves 301 that are inserted into the pin 302 are fixedly connected to the circumferential surface of the winding wheel 604. The pin sleeves 301 are evenly distributed circumferentially with the axis of the winding wheel 604 as the reference. A magnetic plate 304 is fixedly connected to the end of the pin 302, and the magnetic plate 304 is magnetically attracted to the iron pin sleeves 301. After the winding wheel 604 rotates a suitable number of times, the pin 302 is simultaneously inserted into the pin sleeves 301 and the pin hole 303, which can limit the winding wheel 604. At the same time, the magnetic plate 304 can prevent the pin 302 from accidentally falling off through its magnetic force.

[0034] Reference Figure 3 As shown, the pull rope structure 7 includes a connecting block 701 fixedly connected to the lower side of the insert rod 502. The rod body 402 has a movable groove 2 for the connecting block 701 to move up and down. A guide wheel 703 is rotatably connected to the upper side of the rod body 402. A connecting rope 702 is fixedly connected to the connecting block 701. The other end of the connecting rope 702 passes over the upper sides of the guide wheel 703 and the first guide wheel 603 in sequence and is fixedly connected to the linkage block 605. When the connecting rope 602 is wound up, causing the linkage block 605 to move downwards, the connecting rope connected to the linkage block 605... As the end of 702 moves downward, guided by guide wheel 603 and guide wheel 703, it can drive the insertion rod 502 to rise synchronously. It is worth mentioning that since guide wheel 603 and all guide wheels are concave, connecting rope 602 and connecting rope 702 will not be affected by movement even when they are located in them. To avoid wear, two guide wheels 603 can be set side by side at the same height (only one is shown in the figure) according to the actual situation. This can avoid wear. This method can be adapted by those skilled in the art when implementing it, and will not be described in detail here.

[0035] Reference Figure 4As shown, the second rope structure 8 includes a connecting block 801 fixedly connected to the lower side of the insert rod 503, and a movable groove 3 for the connecting block 801 to move up and down is provided on the rod body 403. A guide wheel 803 is rotatably connected to the upper side of the rod body 403, and a guide wheel 804 is rotatably connected to the upper side wall of the rod body 401. A connecting rope 802 is fixedly connected to the connecting block 801. The other end of the connecting rope 802 passes through the upper side of the guide wheel 803 and the guide wheel 804 and abuts against the linkage block 605. A ring 805 is fixedly connected to the side wall of rod 401, and a connecting rope 802 passes through the ring 805 and is connected to the linkage block 605. When the connecting rope 602 is wound up and moves the linkage block 605 down, the connecting rope 802 passing through the ring 805 moves down with it. Under the guidance of the guide wheel 804 and the guide wheel 803, the insertion rod 503 can be driven to rise at the same time. The ring 805 is designed to prevent wear between the connecting rope 802 and the edge of rod 401 through its smooth surface.

[0036] Reference Figure 5 As shown, the rope structure 39 includes a connecting block 4901 fixedly connected to the lower side wall of the other side of the insert rod 3503. A movable groove 4 for the connecting block 4901 to move up and down is provided on the other side wall of the rod 3503. Guide wheels 5904 and 6902 are rotatably connected to the upper and lower sides of the side wall of the rod 3503, respectively. A connecting block 5906 is fixedly connected to the lower side of the insert rod 4504, and a movable groove 5 for the connecting block 5906 to move up and down is provided on the side wall of the rod 4504. A guide wheel 7905 is rotatably connected to the upper side wall of the rod 4504. A connecting block 4901 is fixedly connected to the bottom surface of the connecting block 4901.

When insert rod 3 503 rises, the lower end of connecting rope 4 903 rises with it. Since connecting rope 4 903 abuts and passes under guide wheel 6 902, connecting rope 4 903 on the other side of guide wheel 6 902 is in a descending state. Under the guidance of guide wheel 5 904 and guide wheel 7 905, it drives insert rod 4 504 to rise synchronously.

[0037] Reference Figure 2 As shown, three C-shaped guard plates 10 are fixedly connected between the four hollow rods 4, and the horizontal parts of the connecting ropes 702, 802, and 903 are respectively located in the three C-shaped guard plates 10. The three C-shaped guard plates 10 can protect the ropes located in the horizontal parts.

[0038] The working principle of this utility model:

[0039] When it is necessary to lift the roof panel 2, the connecting rope 602 can be wound around the winding wheel 604 by rotating the winding wheel 604. At this time, under the guidance of the guide wheel 603, the insert rod 501 connected to the other end of the connecting rope 602 rises in the rod body 401. At the same time, the ends of the connecting rope 702 connected to the bottom of the insert rod 502 and the connecting rope 802 connected to the bottom of the insert rod 503 move down with it through the connection of the linkage block 605. Under the reaction force, the insert rod 502 and the insert rod 503 rise together with the insert rod 501. At the same time, the connecting rope 903 connected to the bottom of the insert rod 503 rises with it. Under the guidance of the guide wheel 902, the guide wheel 504 and the guide wheel 705, the insert rod 504 rises together with the insert rod 503. In this way, the four movable rods 5 can be raised and lowered simultaneously in the four hollow rods 4.
