Description

Technical Field

[0001] This utility model relates to a hinge plate, and more particularly to a reinforced hinge plate for containers. Background Technology

[0002] Containers are the most important medium of transport in international trade, playing a crucial role, especially in the import and export of goods overseas. The container body and doors are typically connected by a hinge structure, with the hinge plate being the core component. Currently, hinge plates are usually manufactured by forging and then welded to the container doors.

[0003] As a core component connecting the container body and doors, the hinge plate's service life, safety, and production cost all affect the container's overall lifespan, safety, and cost, making it a crucial consideration in product development. Current technology typically uses reinforcing ribs on the front of the hinge plate to improve rigidity and strength, but this reinforcement is insufficient, and excessive ribs on the front of the hinge plate can complicate manufacturing processes and increase product costs.

[0004] Furthermore, since containers are primarily used in maritime transport, they are susceptible to seawater corrosion, leading to material deformation, reduced rigidity, and significantly diminished service life and safety. In particular, gaps easily exist at the welded joints between the hinge plates and the doors, making them even more vulnerable to seawater corrosion. To mitigate this, existing technologies typically involve applying sealant around the hinge plate welds. However, since sealant is generally a viscous paste or liquid, it is easily rubbed off or detached under gravity or due to movement before it solidifies. This results in less sealant actually solidifying at the weld, significantly reducing the sealing effect, and potentially even rendering the sealant ineffective due to insufficient coverage of the weld gaps.

[0005] In summary, existing technologies lack effective solutions to improve the strength and rigidity of hinge plates and address the problem of poor sealant application. Therefore, a new technical solution is urgently needed to address these issues. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a reinforced container hinge plate with simple structure and low cost. This hinge plate can simultaneously enhance the rigidity and strength of the hinge plate and support the sealant to improve the sealing effect.

[0027] 130 Box Door Detailed Implementation

[0028] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, it should be understood that this utility model is not limited to the embodiments described below, and the technical concept of this utility model can be implemented in combination with other known technologies or other technologies with the same functions as those known technologies.

[0029] Unless otherwise specified, qualifiers such as "first" and "second" in this document do not refer to limitations on chronological order, quantity, or importance, but are merely used to distinguish one technical feature from another in this technical solution. Similarly, qualifiers such as "one" do not refer to limitations on quantity, but describe technical features not mentioned previously. Likewise, modifiers such as "approximately" or "about" preceding numerals in this document usually include the number itself, and their specific meaning should be understood in conjunction with the context. Similarly, unless a noun is modified by a specific quantifier, it should be considered in this document as including both singular and plural forms; the technical solution may include either a singular or plural number of the technical feature.

[0030] In the following description of specific embodiments, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used for description. However, terms such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "axial", and "radial" should be understood as convenient terms and should not be understood as limiting terms.

[0031] by Figure 1-1 For example, for ease of explanation, the orientation of the hinge plate is defined as follows: one end of the hinge plate bushing 1 is the front end direction, and one end of the hinge plate fixing part 5 is the rear end direction. The left side of the viewing angle from the rear end of the hinge plate extending to the front end is the left end direction, and the right side of the viewing angle from the rear end of the hinge plate extending to the front end is the right end direction.

[0032] Figures 1-1 to 1-4 The figures shown are, in order, a perspective view, a bottom view, a top view, and a side view of a hinge plate structure in the prior art. From front to rear, it comprises the following parts: a bushing 1, a first bent portion 2, a connecting portion 3, a second bent portion 4, and a fixing portion 5. The portion of the bushing 1 near the rear end connects to the portion of the first bent portion 2 near the front end; the portion of the first bent portion 2 near the rear end connects to the portion of the connecting portion 3 near the front end; the portion of the connecting portion 3 near the rear end connects to the portion of the second bent portion 4 near the front end; and the portion of the second bent portion 4 near the rear end connects to the portion of the fixing portion 5 near the front end. The hinge plate bushing 1 is used to accommodate a pin, meaning the pin passes through the bushing 1, and washers (not shown) are installed on both sides of the pin.

[0033] The lower surface of the fixing part 5 includes a recess 6. This recess 6 primarily serves to save material costs and also provides a certain degree of rigidity, preventing deformation of the hinge plate caused by repeated opening and closing of the container door 130 over a long period. A first protruding ridge 81 is formed between the recess 6 and the first side 71, a second protruding ridge 82 is formed between the recess 6 and the second side 72, a third protruding ridge 83 is formed between the recess 6 and the third side 73, and a fourth protruding ridge 84 is formed between the recess 6 and the fourth side 74.

[0034] The hinge plate fixing part 5 is used to fix it to the container door 130. Welding is typically used, specifically welding the second side 72, third side 73, and fourth side 74 of the lower surface of the fixing part 5 as welding points (welding surfaces) to achieve a fixed connection. After welding, the planes between the protrusions and sides of the lower surface of the fixing part 5, excluding the recess 6, will fit against the container door 130. Meanwhile, because the space where the first side 71 fits against the container door 130 is relatively small, welding is usually not performed at this location.

[0035] The main problems with existing hinge plates in practical use are as follows:

[0036] Question 1:

[0037] As mentioned earlier, in the prior art, the hinge plate is typically welded to the door 130 using the second side 72, third side 73, and fourth side 74 of the fixing part as welding points. After installation, the connection between the hinge plate and the door 130 is only the fixing part; the other parts (sleeve, first bend, connecting part, and second bend) are not directly fixed to the door 130. Therefore, during the opening and closing of the door 130, stress will mainly concentrate at the angle where the rear end of the connecting part and the front end of the second bend connect. If the rigidity and strength at this point are insufficient, it can easily lead to deformation or even breakage of the hinge plate, affecting the service life and safety of the container.

[0038] Question 2:

[0039] In existing technologies, when hinge plates are welded to the container door 130, the welding surfaces are only the surfaces corresponding to the second side 72, the third side 73, and the fourth side 74, and not the first side 71. Therefore, after welding, the transition points between the first side 71 and the third side 73, and between the first side 71 and the fourth side 74, will exhibit a situation where one side is welded while the other side is not. In other words, the connection between the first side 71 and the third side 73 is a transition point between the welded and unwelded surfaces, and the connection between the first side 71 and the fourth side 74 is also a transition point between the welded and unwelded surfaces. During actual use of the container, seawater easily accumulates at these points, corroding the hinge plates. Furthermore, seawater can easily enter the gap between the hinge plates and the container door 130 through these points, leading to further corrosion and rust.

[0040] To address this issue, the current solution in the prior art is to apply sufficient sealant at the transition points between the first side 71 and the third side 73, and between the first side 71 and the fourth side 74, to achieve a certain sealing effect and mitigate seawater intrusion and corrosion. However, this method does not effectively solve the problem. The reasons are as follows: Firstly, because the sealant is a flowable paste or liquid and requires time to solidify, when applied to the transition points, it easily flows to other locations or drips onto the ground under gravity, resulting in insufficient sealant in the final container, weakening or even eliminating the sealing effect. Secondly, during container use, since there is no structure to support the sealant applied at the transition points, it is easily detached due to poor adhesion, seawater corrosion leading to deformation, or external forces, resulting in loss of sealing and waterproofing effects, ultimately reducing the service life of the hinges and container doors 130.

[0041] To alleviate the above problems, regular inspections and maintenance of the container hinges are necessary, and sealant needs to be reapplied when necessary. On the one hand, this leads to increased labor and material costs; on the other hand, since the sealant needs to cure before it becomes effective, the container cannot be used normally during this period, resulting in a decrease in container utilization efficiency; furthermore, even with regular inspections and reapplied sealant, corrosion cannot be completely prevented.

[0042] To address the aforementioned two technical challenges in the existing technology, the present invention provides a reinforcing section at the connection between the connecting part and the second bending part. This section simultaneously enhances the rigidity and strength of the hinge plate and supports the sealant to improve the sealing effect, thus effectively solving the above-mentioned technical problems. For a detailed description of the technical solution of this invention, please refer to the following embodiments.

[0043]

Example 1

[0044] Figures 2-1 to 2-4 The following are, in order, a perspective view, a bottom view, a side view, and a rear view of the hinge plate structure of Embodiment 1 of this utility model. From front to rear, it includes the following parts: bushing 1, first bent portion 2, connecting portion 3, second bent portion 4, and fixing portion 5. The hinge plate structure of Embodiment 1 of this utility model is generally similar to the hinge plate in the prior art; the similarities will not be repeated here. The difference between the hinge plate structure of Embodiment 1 and the prior art is that the hinge plate of Embodiment 1 includes a reinforcing portion 9, which is disposed between the connecting portion 3 and the second bent portion 4. The reinforcing portion 9 includes a first end 91 and a second end 92. The first end 91 is connected to the lower surface of the connecting portion 3, and the second end 92 is connected to the lower surface of the second bent portion 4.

[0045] Figure 2-5 This is a three-dimensional schematic diagram of the hinge plate after it has been welded to the door 130 in Embodiment 1 of this utility model.

[0046] By providing this reinforcing part 9, the following beneficial technical effects can be achieved:

[0047] First, a reinforcing part 9 is set at the bending point where the stress is concentrated in the hinge plate. Without increasing the thickness of the main body of the hinge plate, the strength and rigidity of the hinge plate are improved, which effectively avoids the deformation or breakage of the hinge plate that may occur during long-term use, and improves the service life and safety of the container door 130.

[0048] Secondly, the reinforcing part 9 can serve as a platform (step). After the hinge plate is installed on the door 130, the sealant applied to the first side 71 and the third side 73, as well as the first side 71 and the fourth side 74 of the hinge plate can be supported by the reinforcing part 9, so that the sealant will not flow to other positions or drip onto the ground, thereby avoiding the reduction or even loss of sealing effect due to insufficient amount of sealant solidified at the transition point.

[0049] Third, after the hinge plate is welded to the door 130 and the sealant is applied and solidified, the reinforcing part 9 can serve as an attachment platform for the sealant, preventing the sealant from cracking or falling off due to external forces or other reasons during long-term use of the hinge plate, which would lead to a reduction or even loss of the sealing effect.

[0050] Preferably, the reinforcing part 9 includes two reinforcing blocks symmetrically arranged along the center line of the hinge plate in the left-right direction. Its superior technical effect is that, on the one hand, the strength distribution of the hinge plate is more uniform, and it is not easy for uneven stress to cause deformation or breakage during use. On the other hand, it can support the sealant applied at the first side 71 and the third side 73, and the first side 71 and the fourth side 74, thereby improving the sealing effect.

[0051]

Example 2

[0052] Figures 3-1 to 3-2 The images shown are, in order, a perspective view and a bottom view of the hinge plate structure of Embodiment 2 of this utility model.

[0053] The hinge plate structure of Embodiment 2 of this utility model is generally similar to that of Embodiment 1, and the similarities will not be repeated here. The hinge plate structure of Embodiment 2 differs from that of Embodiment 1 in that the hinge plate of Embodiment 2 also includes a groove 120. The groove 120 is disposed between the connecting part 3 and the second bending part 4. The groove 120 includes a first end and a second end, the first end being connected to the lower surface of the connecting part 3 and the second end being connected to the lower surface of the second bending part 4. The groove 120 is disposed on the outside of the reinforcing part 9. The outside here should be understood as follows: when the reinforcing part 9 is disposed on the left side of the center line of the hinge plate in the left-right direction, the groove 120 is disposed on the left side of the reinforcing part 9; when the reinforcing part 9 is disposed on the right side of the center line of the hinge plate in the left-right direction, the groove 120 is disposed on the right side of the reinforcing part 9.

[0054] The superior technical effect of the groove 120 is that when the sealant is applied to the transition between the first side 71 and the third side 73, and the transition between the first side 71 and the fourth side 74 of the hinge plate fixing part, the groove 120 can increase the contact area between the sealant and the hinge plate, thereby improving the adhesion effect of the sealant. This allows the sealant to adhere more firmly to the hinge plate and the door 130 after curing, better preventing the sealant from being damaged or falling off due to external force or other reasons, avoiding the reduction and loss of the sealing effect, and thus ensuring to the greatest extent that seawater will not enter the gap between the hinge plate and the door 130, causing rust and corrosion.

[0055] The embodiments described in this specification are merely preferred embodiments of the present invention. These embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of the present invention. All technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation should be within the scope of the present invention.
