[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] See attached document Figures 1-5 A reinforcing structure for a trailer tailgate connecting seat includes: a tailgate connecting hinge seat and a pulling mechanism.

[0031] Specifically, the tailplate connecting hinge includes two hinge plates 200, and an extension plate 210 is fixedly installed on the side wall of the hinge plate 200. The extension plate 210 and the hinge plate 200 are integrally formed. The extension plate 210 is installed on the mounting base 100; the pulling mechanism is disposed on the extension plate 210, and the end of the pulling mechanism away from the extension plate 210 is connected to the mounting base 100.

[0032] Combination Figure 1 as well as Figure 2 As shown, in one embodiment of this utility model, the mounting base 100 includes a connecting frame 110 and a side connecting plate 120, the side connecting plate 120 being fixedly connected to the connecting frame 110. The mounting base 100 is composed of the connecting frame 110 and the side connecting plate 120, the side connecting plate 120 being installed at an angle, with its two sides respectively connected to the upper and lower inner walls of the connecting frame 110.

[0033] In one embodiment of this utility model, a through groove is provided on the connecting frame 110, and the extension plate 210 extends movably through the through groove to the inner side of the connecting frame 110. Specifically, after the through groove is provided on the connecting frame 110, when the hinge plate 200 is installed, the extension plate 210 on the hinge plate 200 can first pass through the groove, and then the extension plate 210 and the mounting base 100 are welded and fixed together.

[0034] Combination Figure 3 , Figure 4 as well as Figure 5In one embodiment of this utility model, the pulling mechanism includes a lead screw 300, a pull plate 310, and a first nut 340; the pull plate 310 is fixedly installed on the end wall of the lead screw 300, and a connecting groove 320 is provided on the extension plate 210, into which the pull plate 310 is inserted; the lead screw 300 is provided on the side wall of the side connecting plate 120, and the lead screw 300 extends movably through the inside of the through groove 330 and extends to the outside of the side connecting plate 120; the first nut 340 is threadedly installed on the lead screw 300, and the first nut 340 is used to lock and fix the lead screw 300. One of the pull plates 310 is used to pull two extension plates 210. Considering the actual installation problem, a through slot 330 is provided on the side connecting plate 120. The size of the pull plate 310 is larger than that of the connecting plate 210, that is, the pull plate 310 can pass through the through slot 330 and enter between the side connecting plate 120 and the connecting frame 110. After the pull plate 310 enters, the position of the pull plate 310 can be adjusted by moving the screw 300 laterally. After adjusting the position, the pull plate 310 can pass through the connecting slot 320 on one side. Then, the pull plate 310 is moved further so that it can be installed in both connecting slots 320 (e.g., ...). Figure 5 (as shown in the diagram), then install the first nut 340 onto the lead screw 300, and then continuously rotate the first nut 340 to lock and fix the lead screw 300.

[0035] Combination Figure 3 as well as Figure 5 As shown, in one embodiment of this utility model, a connecting plate 350 is further included. Two through holes are formed at both ends of the connecting plate 350, and two adjacent lead screws 300 are respectively inserted into the two through holes. A second nut 360 is threaded onto the lead screw 300, and the second nut 360 is used to lock and fix the connecting plate 350. To further enhance the stability of the lead screws 300 installed on the side connecting plate 120, the connecting plate 350 is provided, that is, the connecting plate 350 is sleeved on two adjacent lead screws 300, and then the connecting plate 350 is locked and fixed by the second nut 360. This achieves the connection between the two adjacent lead screws 300, thereby improving the stability of the lead screws 300 installed on the side connecting plate 120.

[0036] In this embodiment, the working principle of the device is as follows: In the practical application of the reinforced structure of the trailer tailgate connecting seat, the basic structure is first assembled by welding the side connecting plate 120 of the mounting seat 100 to the upper and lower inner walls of the connecting frame 110 at an incline to form a triangular support frame. Then, the two hinge plates 200 of the tailgate connecting hinge seat are fitted to the outer wall of the connecting frame 110, so that the extension plate 210 integrally formed by the hinge plate 200 passes through the pre-set through slot of the connecting frame 110 and extends to the inner side, completing the initial positioning. Subsequently, the traction mechanism is assembled by connecting the screw 300 with the pull plate 310 from the... The outer side of the side connecting plate 120 passes through the through groove 330. The position is adjusted so that the pull plate 310 is embedded in the connecting groove 320 of the two extension plates 210. Then, the first nut 340 is screwed into the end of the lead screw 300 on the outer side of the side connecting plate 120 to lock it. The pull plate 310 generates lateral tension on the extension plate 210. Then, the through holes at both ends of the connecting plate 350 are fitted onto the adjacent lead screw 300 and fixed by the second nut 360, so that the dispersed lead screws 300 form an integral force unit. At the same time, the contact part between the extension plate 210 and the connecting frame 110 is welded to achieve a dual force distribution of welding shear resistance and mechanical tension resistance.

[0037] When the trailer tailgate is in operation, its weight and impact force are first transmitted to the hinge plate 200. Part of the vertical force of the hinge plate 200 is transmitted to the connecting frame 110 through the welded part of the extension plate 210 and the connecting frame 110, and another part is transmitted to the pull plate 310 through the connecting groove 320 of the extension plate 210. The pull plate 310 then transmits the force to the lead screw 300. The lead screw 300 transmits the force to the side connecting plate 120 with the cooperation of the first nut 340 and the side connecting plate 120, and finally distributes it to the entire mounting seat 100. The lateral reinforcement unit composed of the connecting plate 350 and the second nut 360 can offset the lateral deformation of the lead screw 300, avoid the welded part from tearing due to local stress concentration, and improve the installation stability of the tailgate connecting hinge seat.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
