Description

Technical Field

[0001] This utility model relates to the technical field of low-carbon cast steel parts, specifically a high-strength, easily shaped low-carbon cast steel part. Background Technology

[0002] Low-carbon cast steel parts are workpieces made from cast steel with a low carbon content. Their carbon content is generally between 0.03% and 0.3%, which gives them good toughness and weldability. Compared to high-carbon cast steel, low-carbon cast steel parts are less prone to cracks and can withstand greater impact and vibration. They are widely used in machinery manufacturing, the automotive industry, aerospace, and other fields; for example, low-carbon cast steel parts are commonly used in automotive components and aircraft structural parts.

[0003] According to patent CN217977836U, a high-strength, easily shaped, low-carbon cast steel part is used to protect the connection between the cast steel part body and the pipeline, which can reduce the impact of environmental factors on the fixation of the connection and allow the cast steel part body to be disassembled smoothly. In the above patent, the environmental impact is reduced by adding a protective structure between the cast steel part body and the pipeline. However, it does not take into account that the connection between the protective structure and the pipeline will still rust, causing the pipeline to rust partially at the connection with the cast steel part body, making it inconvenient to disassemble later. At the same time, the surfaces of the first protective sleeve and the second protective sleeve in the above patent are fixed by screws, and these screws are also easy to become unable to be removed under the influence of the environment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength, easily shaped, low-carbon cast steel part, including a cast steel part body, a connecting pipe fixedly connected to the surface of the cast steel part body, a protective component sleeved on the surface of the connecting pipe, and a fixing component fixedly connected to the front of the protective component.

[0005] The protective assembly includes a semi-circular sleeve plate 1, a protective sleeve 1 fixedly connected to the left end of the semi-circular sleeve plate 1, a semi-circular sleeve plate 2 fixedly connected to the left end of the protective sleeve 1, a special-shaped locking platform fixedly connected to the right end of the semi-circular sleeve plate 1, a limiting plate 1 fixedly connected to the bottom of the protective sleeve 1, a connecting shaft sleeved at the rear end of the limiting plate 1, a limiting plate 2 sleeved on the surface of the connecting shaft, and a protective sleeve 2 fixedly connected to the bottom of the limiting plate 2.

[0006] Through the above technical solution, by setting up the connecting pipe and the protective and fixing components connected to it, the cast steel parts can be better protected during use. At the same time, the connection between these components also helps to improve the stability of the overall structure of the cast steel parts. By setting up the special-shaped clamping platform, the connection position between the cast steel parts and the connecting pipe can be completely protected, avoiding rusting at the connection position after long-term use, which would make it impossible to disassemble.

[0007] As a further improvement to the above solution, the number of the first semicircular sleeve plate is set to four, and the four cast steel parts are symmetrically and evenly distributed on the surface of the connecting pipe. The ends of the first semicircular sleeve plates that are close to each other are fixed by bolts.

[0008] Through the above technical solution, the quantity and distribution of the semi-circular sleeve plate one enable the protective components to be evenly distributed on the surface of the connecting pipe, providing all-round protection for the connecting pipe.

[0009] As a further improvement to the above solution, the inner wall of the irregular-shaped card table is in contact with the surface of the cast steel body.

[0010] Through the above technical solution, the inner wall of the irregular card table is in contact with the surface of the cast steel body, which can enhance the connection stability between the protective component and the cast steel body, and protect the surface of the cast steel body and the surface of the connecting pipe.

[0011] As a further improvement to the above solution, the first protective sleeve and the second protective sleeve are concentric.

[0012] Through the above technical solutions, the concentric design helps to ensure the synergy between protective sleeve one and protective sleeve two during the protection process, enabling them to better perform their protective functions around the connecting pipe, reduce blind spots in protection, and improve the protective effect.

[0013] As a further improvement to the above solution, the fixing component includes an extension plate, a protective cover is fixedly connected to the inner wall of the extension plate, a fixing post is fixedly connected to the inner wall of the protective cover, a movable sleeve is rotatably connected to the surface of the fixing post, a screw is fixedly connected to the bottom of the movable sleeve, and a clamping plate is threadedly connected to the surface of the screw.

[0014] The above technical solution involves setting a protective cover to thread the card plate onto the surface of the screw, so that the surface of the card plate contacts the surface of the extension plate, thereby fixing the connection position of the first protective sleeve and the second protective sleeve a second time, while the protective cover protects it.

[0015] As a further improvement to the above solution, two extension plates are provided, and the two extension plates are respectively fixed on the front of the first protective sleeve and the second protective sleeve. The protective cover is fixed on the surface of the extension plate located inside the first protective sleeve.

[0016] With the above technical solution, the two extension plates are fixed to the front of the first protective sleeve and the second protective sleeve respectively. This layout allows the fixing components to be reasonably distributed on the protective components, while the protective cover is fixed to the surface of the extension plate located inside the first protective sleeve, which can protect the internal structure of the fixing components.

[0017] As a further improvement to the above solution, the top of the card plate contacts the bottom of the extension plate near the front of the second protective sleeve.

[0018] With the above technical solution, the top of the card plate contacts the bottom of the extension plate near the front of the second protective sleeve. This design can effectively limit the relative position between the two extension plates, thereby further improving the fixing effect of the fixing component on the protective component and ensuring the stability of the entire cast steel structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, by setting up a special-shaped clamping platform, can completely protect the connection position between the cast steel body and the connecting pipe, preventing rust from forming at the connection position after long-term use, thus avoiding the inability to disassemble.

[0021] This utility model uses a protective cover to thread the card plate onto the surface of the screw rod, so that the surface of the card plate contacts the surface of the extension plate, thereby fixing the connection position of the first protective sleeve and the second protective sleeve, while the protective cover protects it.

[0030] Please combine Figure 1-5 This embodiment of a high-strength, easily shaped, low-carbon cast steel part includes a cast steel part body 1, a connecting pipe 2 fixedly connected to the surface of the cast steel part body 1, a protective component 3 sleeved on the surface of the connecting pipe 2, and a fixing component 4 fixedly connected to the front of the protective component 3.

[0031] Protective component 3 includes a semi-circular sleeve 31, a protective sleeve 32 fixedly connected to the left end of the semi-circular sleeve 31, a second semi-circular sleeve 33 fixedly connected to the left end of the protective sleeve 32, a shaped locking platform 34 fixedly connected to the right end of the semi-circular sleeve 31, a limiting plate 35 fixedly connected to the bottom of the protective sleeve 32, a connecting shaft 36 sleeved at the rear end of the limiting plate 35, a second limiting plate 37 sleeved on the surface of the connecting shaft 36, and a second protective sleeve 38 fixedly connected to the bottom of the limiting plate 37. The semi-circular sleeve 31 is then fitted onto the connecting pipe. On the surface of 2, the irregularly shaped clamping platform 34 contacts the surface of the cast steel body 1, while the protective sleeve 32 and the semi-circular sleeve plate 33 are fitted onto the surface of the connecting pipe 2. Then, through the limiting plate 37, the protective sleeve 38 is rotated so that the semi-circular sleeve plate 31 and the semi-circular sleeve plate 33, which are close to each other, contact each other through the extended side plate at the front end and are fixed by bolts. At this time, the limiting plate 35 and the limiting plate 37 are engaged with each other to seal the connection position between the protective sleeve 32 and the protective sleeve 38.

[0032] There are four semicircular sleeve plates 31. The four cast steel bodies 1 are symmetrically and evenly distributed on the surface of the connecting pipe 2. The ends of the semicircular sleeve plates 31 that are close to each other are fixed by bolts.

[0033] The inner wall of the irregular-shaped card table 34 is in contact with the surface of the cast steel body 1.

[0034] Protective sleeve 1 (32) and protective sleeve 2 (38) are concentric.

[0035] The fixing component 4 includes an extension plate 41, a protective cover 42 fixedly connected to the inner wall of the extension plate 41, a fixing post 43 fixedly connected to the inner wall of the protective cover 42, a movable sleeve 44 rotatably connected to the surface of the fixing post 43, a screw 45 fixedly connected to the bottom of the movable sleeve 44, and a clamping plate 46 threadedly connected to the surface of the screw 45. The clamping plate 46 is threadedly connected to the surface of the screw 45, so that the surface of the clamping plate 46 contacts the surface of the extension plate 41, thereby fixing the connection position of the first protective sleeve 32 and the second protective sleeve 38 for a second time.

[0036] There are two extension plates 41. The two extension plates 41 are fixed to the front of the first protective sleeve 32 and the second protective sleeve 38 respectively. The protective cover 42 is fixed to the surface of the extension plate 41 located inside the first protective sleeve 32.

[0037] The top of the card plate 46 contacts the bottom of the extension plate 41 near the front of the protective sleeve 38.

[0038] The implementation principle of a high-strength, easily shaped, low-carbon cast steel part in this embodiment is as follows: When protecting the cast steel part body 1, the semi-circular sleeve plate 31 is fitted onto the surface of the connecting pipe 2, and the irregular clamping platform 34 contacts the surface of the cast steel part body 1. At the same time, the protective sleeve 32 and the semi-circular sleeve plate 33 are fitted onto the surface of the connecting pipe 2. Then, through the limiting plate 37, the protective sleeve 38 is rotated so that the semi-circular sleeve plate 31 and the semi-circular sleeve plate 33, which are close to each other, contact each other through the extended side plate at the front end and are fixed by bolts. At this time, the limiting plate 35 and the limiting plate 37 are interlocked, sealing the connection position of the protective sleeve 32 and the protective sleeve 38. Through the irregular clamping platform 34, the connection position between the cast steel part body 1 and the connecting pipe 2 can be completely sealed, preventing rust at the connection position after long-term use, which would make it impossible to disassemble.

[0039] After the semicircular sleeve 1 31 and semicircular sleeve 2 33 are fixed, the clamping plate 46 is threaded onto the surface of the screw 45 through the protective cover 42, so that the surface of the clamping plate 46 contacts the surface of the extension plate 41, and the connection position of the protective sleeve 1 32 and the protective sleeve 2 38 is fixed for a second time, while the protective cover 42 protects it.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
