[0015] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments. However, the specific embodiments and examples described below are for illustrative purposes only and are not limitations to the present utility model.

[0016] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the Figure 1 directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0017] In the description of the present application, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0018] To solve the above technical problems, as Figures 1-4 shown, the present utility model designs an anti-theft reinforced hinge plate assembly structure, including a hinge plate main body 1, a door frame fixing seat 2, a support shaft 3, a pin shaft 4, and a limit connecting member. The door frame fixing seat 2 is used for fixedly connecting with the container door frame, and its bottom plate can be fixed on the container door. Step holes 5 are respectively provided on both side support plates of the door frame fixing seat 2. A rotating shaft support portion 6 is arranged on one side of the hinge plate main body 1. Support shafts 3 are respectively and fixedly arranged at both ends of the rotating shaft support portion 6. The two support shafts 3 are coaxially corresponding. A cavity is provided inside the support shaft 3. A positioning hole 7 communicating with the cavity is provided at the end of the support shaft 3. The limit connecting member is installed in the positioning hole 7 and is used to enable the pin shaft 4 to be connected with the support shaft 3. The limit connecting member is specifically preferably a flat head rivet nut 8. The inner hole of the flat head rivet nut 8 is a threaded hole. When installing the flat head rivet nut 8, first insert its rod body into the positioning hole 7 of the support shaft 3, and then install an adjusting screw rod and rotate it to make it contract reversely, so as to form two limit protrusions on the upper and lower sides of the positioning hole 7 of the support shaft 3, so that the flat head rivet nut 8 is firmly fixed in the positioning hole 7. The cavity inside the support shaft 3 plays a role of making way. The pin shaft 4 is provided with an external thread section that cooperates with the threaded hole of the flat head rivet nut 8, and it is fixed on the flat head rivet nut 8 by means of threaded connection. The pin shaft 4 is coaxially corresponding to the support shaft 3. The small hole of the step hole 5 is sleeved outside the smooth rod of the pin shaft 4 and is in rotational cooperation with it. The large hole of the step hole 5 is sleeved outside the support shaft 3 and is in rotational cooperation with it. By using the flat head rivet nut 8 as the limit connecting member, a fixed mechanism that is difficult to disassemble is formed. The installation method of the rivet nut makes it difficult to remove it without professional tools, thus effectively preventing illegal disassembly and theft behaviors. Moreover, it is hidden inside the door frame fixing seat 2, which can achieve the effects of anti-theft and anti-disassembly. Secondly, the rotational connection of the support shaft 3, the pin shaft 4 and the door frame fixing seat 2 forms a double connection mechanism. Even if the pin shaft 4 is damaged, the hinge plate can still rotate normally, which improves the safety and anti-theft performance of the container door and also improves the stability of the hinge plate during use.

[0019] Furthermore, the rotating shaft support portion 6 and the hinge plate main body 1 are integrally formed, making the structure more stable, reducing the possibility of deformation or damage caused by external forces. The rotating shaft support portion 6 is cylindrical and its diameter is larger than the thickness of the hinge plate main body 1, increasing the strength of the support portion, enabling the hinge plate to withstand greater forces, extending the service life. The integrally formed rotating shaft support portion 6 can more effectively disperse the forces acting on the hinge plate, reducing stress concentration, thereby improving the durability and reliability of the overall structure.

[0020] Furthermore, reinforcing ribs 9 are provided on the hinge plate main body 1, increasing its load-bearing capacity, enabling the hinge plate to withstand greater loads. The reinforcing ribs 9 can effectively resist the deformation of the hinge plate that may occur under repeated use or heavy loads, maintaining the geometric stability of the hinge plate.

[0021] Furthermore, the hinge plate main body 1 is made of a metal material, having high strength and hardness, making the hinge plate more robust and durable, capable of withstanding external impacts and abrasions. It can be surface-treated according to different usage environments, such as galvanizing, chrome plating or other anti-corrosion coatings, to adapt to various climatic and environmental conditions.

[0022] The above embodiments are only the preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made by those skilled in the art according to the structure, shape and principle of the present invention should be covered within the protection scope of the present invention.
