Description

Technical Field

[0001] This utility model relates to the field of containers and the locking rod structure of container doors, and in particular to a protective large bracket that fixes the locking rod to the container door through a bushing. Background Technology

[0002] As the most important transport medium for international warehousing and logistics, shipping containers play a crucial role, especially in the overseas transport of imported or exported goods. However, the operating environment of shipping containers is often extremely harsh; the main reasons for the aging and even failure of various container components (including large bracket bushings) include, but are not limited to: material aging caused by ultraviolet radiation, mechanical impact caused by collisions, and material deterioration caused by corrosive media. During the assembly process of a container, the weight of the locking bars can also put significant stress on related fastening components.

[0003] Specifically, the large bracket used to secure the locking bar to the container door offers limited protection for the bushings, making them particularly vulnerable to damage. On one hand, existing large brackets primarily use two through-holes to engage with bosses on the bushings within the bracket, securing the bushings in place. However, these bushing bosses, typically made of plastic, are prone to damage from external forces or material aging during use. On the other hand, existing large brackets require the bushing bosses to withstand the full shear force from the locking bar. While bushings made of high-quality materials can withstand normal use, the existing large bracket design leaves the bushings lacking sufficient durability when facing impacts exceeding design limits.

[0004] In view of this, designing a large bracket that can significantly improve the service life of bushings while ensuring compatibility with existing bushing designs is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides a protective large bracket, which is specifically achieved through the following technical solution.

[0006] This utility model protects a protective large bracket, comprising a U-shaped bracket body and two flat mounting plates. The two straight edges of the large bracket body are respectively connected to the two flat mounting plates. Each flat mounting plate is provided with at least one mounting hole. At least one of the two U-shaped edges of the large bracket body is provided with a skirt, which extends towards the center of the large bracket body. The bottom of the U-shaped cross-section of the large bracket body is provided with two blind hole fixing holes, which cover the boss on the bushing, protecting the bushing boss from ultraviolet rays, corrosive media, and external impacts.

[0007] Furthermore, the skirt covers the entire length of the U-shaped edge of the large bracket body, further protecting the upper and lower edges of the bushing in the large bracket.

[0008] Furthermore, the skirt only covers a portion of the length of the U-shaped edge of the main body of the large bracket.

[0009] Furthermore, the skirt intermittently covers a portion of the length of the U-shaped edge of the large bracket body.

[0010] Furthermore, the skirt is connected to the main body of the large bracket by welding.

[0011] Furthermore, the skirt is formed by bending a portion reserved on the main body of the large bracket.

[0012] Furthermore, the planar mounting plate is connected to the main body of the large bracket by welding.

[0013] Furthermore, the flat mounting plate is formed by bending a portion reserved on the main body of the large bracket.

[0014] Furthermore, the blind hole fixing hole is formed in one step by stamping.

[0015] Furthermore, the blind hole fixing hole consists of a through hole and a protective cap welded to the edge of the through hole.

[0016] Compared with the prior art, the present invention has at least the following advantages: First, the protective bracket distributes the shear force borne by the bushing boss through the skirt, reducing the pressure and probability of damage to the bushing boss; Second, the protective bracket at least partially isolates the bushing from ultraviolet rays and corrosive media, delaying the material aging of the bushing boss and its upper and lower edges; Third, the skirt of the protective bracket protects the bushing boss and its upper and lower edges from external impacts, reducing the probability of bushing breakage; Fourth, based on the above advantages, the protective bracket is fully compatible with existing bushing designs, eliminating the need for redesigned bushings.

[0032] 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.

[0033] 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.

[0034] The following combination Figures 1 to 9 The technical solution of this utility model will be described.

[0035] Figures 1 to 3The figure shows an existing large bracket 01 containing a bushing 02. As can be seen from the figure, the bushing boss 021 protrudes through the through hole fixing hole 014, that is, the bushing boss 021 floats on the surface of the existing large bracket body 011. Therefore, the bushing boss 021 is not only easily affected by ultraviolet rays and corrosive media, which reduces its strength, but it is also easily broken or detached by external impact, directly causing the bushing 02 to lose its connection with the existing large bracket 01 and slide out of the existing large bracket 01.

[0036] Figures 4 to 6 The figure shows the protective bracket 03 of this utility model without the bushing 02. As can be seen from the figure, the protective bracket 03 has skirts 035 at both ends. These skirts 035 serve a dual purpose: firstly, they protect the upper and lower edges of the bushing 02 from ultraviolet radiation, corrosive media, and external impacts; secondly, the two skirts 035, especially the one that contacts the lower edge of the bushing 02 behind the container door after the bracket 03 is installed, also help to distribute the shear force borne by the bushing boss 021, further reducing the pressure on the bushing boss 021 and lowering the probability of damage to the bushing boss 021. The blind hole fixing hole 034 provided on the protective bracket 03 facilitates the fit between the bushing boss 021 and the main body 031 of the protective bracket, while also protecting the bushing boss 021 from ultraviolet radiation, corrosive media, and external impacts. It is easy to understand that although having skirts 035 at both ends of the protective bracket 03 is the preferred design, the skirts 035 at both ends do not serve exactly the same purpose. When the upper or lower skirts 035 are not needed in use, one of the upper and lower skirts 035 can be omitted during the manufacturing process to reduce manufacturing costs.

[0037] Figures 7 to 9 The protective bracket 03 of this utility model, containing the bushing 02, is further shown. As can be seen from the figure, the bushing boss 021 is completely covered in the blind hole fixing hole 034, and the two skirts 035 play a supplementary role in limiting, supporting and fixing the bushing 02. The beneficial effects of this utility model are thus fully demonstrated.

[0038] Regarding the specific setting and length of the 035 hem, it can also be adopted... Figures 4 to 9Other specific embodiments include, but are not limited to: the skirt 035 covering the entire length of the U-shaped edge of the main body 031 of the large bracket, that is, the skirt 035 covering all parts of the bushing 02 except for the part close to the mounting surface of the large bracket 03 (usually a container door). The part of the skirt 035 close to the flat mounting plate 032 can be set to conform to the outer contour of the locking rod, so that the bushing 02 is completely covered by the skirt 035 when viewed from the top and bottom ends of the protective large bracket 03; the skirt 035 can also intermittently cover part of the length of the U-shaped edge of the main body 031 of the large bracket, for example, divided into 4 segments, with a certain distance between each segment, so that the skirt 035 can be bent to form it. Those skilled in the art will readily understand that if the skirt 035 of the protective large bracket 03 is to be formed by bending rather than welding using a thicker plate, the reserved part of the protective large bracket main body 031 cut from the plate and initially processed needs to retain triangular or square cuts for bending.

[0039] Regarding the specific method of forming the blind hole fixing hole 034, this utility model does not limit the specific method. Two methods that are easily adopted by those skilled in the art include: first making a through hole and then sealing the through hole by welding a small cap-like object to form the blind hole fixing hole 034, and directly forming the blind hole fixing hole 034 by one or more stamping processes. Directly stamping to form a blind hole may, to some extent, make the internal edge of the blind hole fixing hole 034 relatively smooth, which is not conducive to the bushing boss 021 being stuck in the blind hole fixing hole 034. However, the upper and lower skirts 035 of the protective large bracket 03 of this utility model can replace or supplement the function of fixing the bushing 02 in the large bracket 03.

[0040] The protective large bracket of this utility model has at least the following advantages: First, the protective large bracket distributes the shear force borne by the bushing boss through the skirt part, reducing the pressure and probability of damage to the bushing boss; Second, the protective large bracket at least partially isolates the bushing from ultraviolet rays and corrosive media, delaying the material aging of the bushing boss and its upper and lower edges; Third, the skirt of the protective large bracket protects the bushing boss and its upper and lower edges from external impacts, reducing the probability of bushing breakage; Fourth, based on the above advantages, the protective large bracket is fully compatible with existing bushing designs, eliminating the need for redesigned bushings.
