Description
Technical Field
[0001] This utility model relates to the field of building construction equipment technology, and in particular to an interior wall chain shaft. Background Technology
[0002] Construction equipment refers to mechanized tools or devices used in the construction process to complete various tasks (such as earthwork excavation, material transportation, component hoisting, concrete pouring, foundation construction, etc.). These devices replace or assist manual labor through mechanized and automated operation to improve construction efficiency, quality, and safety. Interior walls are a common type of construction equipment.
[0003] A search revealed Chinese patent publication number CN206707120U, which discloses an interior wall panel. The panel comprises a foamed cement layer formed by splicing multiple foamed cement boards and a cured layer disposed on both sides of the foamed cement layer. By providing grooves extending along the length direction between adjacent edges of the foamed cement boards and placing conduits within these grooves, the cured layers on both sides of the foamed cement layer cover the conduits. This pre-fabricated conduit within the wall panel avoids damage to the wall caused by buried conduits, prevents cracks or fissures in the wall, and improves the wall's strength.
[0004] Existing interior walls are connected by bolts or welding, which are cumbersome to operate and inconvenient to disassemble, making it difficult to achieve rapid installation. Utility Model Content
[0005] To overcome the above deficiencies, this utility model provides an interior wall chain shaft, which aims to improve the problems (the shortcomings of the existing technology; corresponding to the background technology).
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] The inner wall chain shaft includes a connecting column, a positioning block fixedly connected to the outer wall of the connecting column, a limit component one provided on the outer wall of the positioning block, a rotating shaft one connected to the limit component one, a rotating block rotatably connected to the outer wall of the rotating shaft one, a pressure block fixedly connected to the outer wall of the rotating block, a rotating shaft two fixedly connected to the inner wall of the pressure block, a limit component two provided on the outer wall of the rotating shaft two, a return spring provided inside the pressure block, the limit component two connected to the return spring, and a connecting component provided on the side wall of the positioning block.
[0008] Through the above technical solution: the second limiting component is operated to rotate, and the return spring is compressed and deformed under the pressure of the second limiting component. Then the second limiting component is separated from the surface of the first limiting component, and then the pressure block is pulled. The rotating block rotates with the pressure block. At this time, the pressure block separates from the positioning block, and the connecting component fixed on the outside of the steel mesh can be taken out from the positioning block. Thus, the steel mesh can be quickly connected, and the stability between the inner wall and the steel mesh can be improved.
[0009] As a further description of the above technical solution:
[0010] The limiting component includes a support block, the outer wall of which is fixedly connected to the outer wall of the connecting column, and a limiting block is fixedly connected to the upper surface of the support block.
[0011] Through the above technical solution: the support block serves as the mounting fulcrum for the first rotating shaft, and the limiting block is used to limit the installation position of the second limiting component.
[0012] As a further description of the above technical solution:
[0013] The second limiting component includes a locking block, and the outer wall of the second rotating shaft is rotatably connected to the locking block, and the locking block has a locking groove inside.
[0014] The above technical solution works as follows: when the card block is engaged with one side of the limiting block, the pressure block is restricted to the front side of the limiting block. After the card block is moved to separate from one side of the limiting block, the card slot is used to engage the card block with the upper side of the limiting block to prevent the pressure block from rebounding.
[0015] As a further description of the above technical solution:
[0016] The connecting assembly includes a first connecting block, the outer wall of which is disposed on the side wall of the positioning block, and a second connecting block is fixedly connected to the outer wall of the first connecting block.
[0017] Through the above technical solution: connecting block 2 is used to connect the steel mesh to connecting block 1, and connecting block 1 is used to connect connecting block 2 to the positioning block, thereby completing the connection between the steel mesh and the interlocking shaft.
[0018] As a further description of the above technical solution:
[0019] The outer wall of the card block is set on the outer wall of the limiting block, and the lower surface of the card block is set on the upper surface of the support block.
[0020] The above technical solution utilizes the groove formed by the support block and the limiting block to limit the position of the locking block.
[0021] As a further description of the above technical solution:
[0022] The connecting column includes a surface wear-resistant layer, an anti-corrosion transition layer, a tough buffer layer, and a core load-bearing layer.
[0023] The above technical solution involves using a variety of materials with different properties to form a connecting column. The outermost layer of the connecting column is a surface wear-resistant layer, followed by an anti-corrosion transition layer installed inside the surface wear-resistant layer, and then a tough buffer layer installed inside the anti-corrosion transition layer. The innermost layer of the connecting column is the core load-bearing layer.
[0024] As a further description of the above technical solution:
[0025] The inner wall of the surface wear-resistant layer is fixedly connected to the outer wall of the anti-corrosion transition layer, the inner wall of the anti-corrosion transition layer is fixedly connected to the outer wall of the toughness buffer layer, and the inner wall of the toughness buffer layer is fixedly connected to the outer wall of the core bearing layer.
[0026] The above technical solution achieves the following: the surface wear-resistant layer is composed of alumina ceramic, which reduces the wear rate of the layer and extends its service life. An anti-corrosion transition layer is set inside the surface wear-resistant layer. This layer is made of polytetrafluoroethylene coating, which can shield external corrosive media and prevent corrosive factors from penetrating from the interlayer interface, thereby protecting the inner layer material from corrosion. A tough buffer layer is set inside the anti-corrosion transition layer. This layer can reduce the direct effect of rigid impact on the core load-bearing layer. The innermost layer of the connecting column is the core load-bearing layer, which is made of titanium alloy material. It can withstand alternating stress for a long time, thereby achieving the improvement of wear resistance and corrosion resistance, dynamic load buffering and high strength load-bearing performance, reducing the failure risk caused by single material performance defects, enhancing comprehensive performance and environmental adaptability, and reducing maintenance costs.
[0027] As a further description of the above technical solution:
[0028] The surface wear-resistant layer, anti-corrosion transition layer, and toughness buffer layer are in the shape of hollow cylinders.
[0029] The above technical solution allows the hollow cylinder design to fit tightly between the layers, facilitating processing.
[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, by moving the locking block to make it rotate around the rotating shaft, the return spring undergoes elastic deformation under the compression of the locking block. The return spring is used to help fix the locking block on one side of the limiting block, thereby achieving quick connection of the steel mesh and improving the connection stability between the inner wall and the steel mesh.
[0032] 2. In this utility model, the connecting column is composed of a variety of materials with different properties. The outermost layer of the connecting column is a surface wear-resistant layer, which is made of alumina ceramic. This can reduce the wear rate of the surface wear-resistant layer and extend its service life.

[0039] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0040] Reference Figures 1-3An embodiment of this utility model provides: an inner wall chain shaft, including a connecting column 1, a positioning block 2 fixedly connected to the outer wall of the connecting column 1, a limit component 3 provided on the outer wall of the positioning block 2, a rotating shaft 4 connected to the limit component 3, a rotating block 5 rotatably connected to the outer wall of the rotating shaft 4, a pressure block 6 fixedly connected to the outer wall of the rotating block 5, a rotating shaft 7 fixedly connected to the inner wall of the pressure block 6, a limit component 8 provided on the outer wall of the rotating shaft 7, a return spring 9 provided inside the pressure block 6, the limit component 8 connected to the return spring 9, and a connecting component 10 provided on the side wall of the positioning block 2;
[0041] Specifically, by moving the limiting component 2 8 to rotate around the rotating shaft 2 7, the return spring 9 undergoes elastic deformation under the compression of the limiting component 2 8. The return spring 9 is used to help fix the limiting component 2 8 to one side of the limiting component 1 3. Then, the limiting component 2 8 leaves the surface of the limiting component 1 3, thereby pulling the pressure block 6. Since the rotating block 5 is fixedly connected to the pressure block 6, the rotating block 5 rotates around the rotating shaft 1 4 under the drive of the pressure block 6. At this time, the pressure block 6 separates from the positioning block 2, and then the connecting component 10 is taken out from the positioning block 2. The connecting component 10 is fixed on the outside of the steel mesh, thereby achieving the effect of quickly connecting the steel mesh and improving the stability between the inner wall and the steel mesh.
[0042] Reference Figure 3 The limiting component 3 includes a support block 31, the outer wall of the support block 31 is fixedly connected to the outer wall of the connecting column 1, and the upper surface of the support block 31 is fixedly connected to a limiting block 32.
[0043] Specifically, the support block 31 is used to provide a mounting fulcrum for the rotating shaft 4, while the limiting block 32 is used to limit the installation position of the limiting component 8.
[0044] Reference Figure 3 The limiting component 2 8 includes a locking block 81, and the outer wall of the rotating shaft 2 7 is rotatably connected to the locking block 81. The locking block 81 has a locking groove 82 inside.
[0045] Specifically, by locking the locking block 81 on one side of the limiting block 32, the pressure block 6 is restricted to the front side of the limiting block 32. After the locking block 81 is moved away from one side of the limiting block 32, the locking block 81 is locked on the upper side of the limiting block 32 through the locking groove 82 to prevent the pressure block 6 from rebounding.
[0046] Reference Figure 2 The connecting component 10 includes a first connecting block 101, the outer wall of which is disposed on the side wall of the positioning block 2, and a second connecting block 102 is fixedly connected to the outer wall of the first connecting block 101.
[0047] Specifically, connecting block 2 102 is used to connect the steel mesh to connecting block 1 101, while connecting block 1 101 is used to connect connecting block 2 102 to positioning block 2, thereby completing the connection between the steel mesh and the interlocking shaft.
[0048] Reference Figure 3 The outer wall of the locking block 81 is set on the outer wall of the limiting block 32, and the lower surface of the locking block 81 is set on the upper surface of the support block 31.
[0049] Specifically, the groove formed by the support block 31 and the limiting block 32 restricts the position of the locking block 81.
[0050] Reference Figure 4 The connecting column 1 includes a surface wear-resistant layer 11, an anti-corrosion transition layer 12, a toughness buffer layer 13, and a core bearing layer 14; the inner wall of the surface wear-resistant layer 11 is fixedly connected to the outer wall of the anti-corrosion transition layer 12, the inner wall of the anti-corrosion transition layer 12 is fixedly connected to the outer wall of the toughness buffer layer 13, and the inner wall of the toughness buffer layer 13 is fixedly connected to the outer wall of the core bearing layer 14; the surface wear-resistant layer 11, the anti-corrosion transition layer 12, and the toughness buffer layer 13 are hollow cylinders;
[0051] Specifically, the connecting column 1 is composed of various materials with different properties. The outermost layer of the connecting column 1 is a surface wear-resistant layer 11, which is made of alumina ceramic. Alumina ceramic has ultra-high hardness and low friction characteristics, which can reduce the surface wear rate and extend the service life. Subsequently, an anti-corrosion transition layer 12 is installed on the inner side of the surface wear-resistant layer 11. The anti-corrosion transition layer 12 is made of polytetrafluoroethylene (PTFE) coating. PTFE coating is chemically inert, which allows the anti-corrosion transition layer 12 to shield against external corrosive media. At the same time, PTFE, with its excellent adhesion, fills the microscopic gaps between the connecting column 1 and the internal structure, forming an "anti-corrosion isolation zone" to prevent corrosive agents from penetrating from the interlayer interface and protect the inner layer material. The core bearing layer 14 is subjected to corrosion. Subsequently, a tough buffer layer 13 is installed on the inner side of the anti-corrosion transition layer 12. Nitrile rubber has high elasticity, which allows the tough buffer layer 13 to convert external dynamic loads into elastic deformation energy, reducing the direct effect of rigid impact on the core bearing layer 14. The innermost part of the connecting column 1 is the core bearing layer 14, which is made of titanium alloy. Titanium alloy has excellent fatigue strength limit and is not prone to crack propagation under cyclic load. This allows the core bearing layer 14 to withstand alternating stress for a long time, thereby achieving performance improvement in wear resistance, corrosion resistance, dynamic load buffering, and high load-bearing capacity. This avoids the failure risk caused by the shortcomings of a single material, improves comprehensive performance and environmental adaptability, and reduces maintenance costs.
[0052] Working principle: By moving the locking block 81 to rotate around the second rotating shaft 7, the return spring 9 undergoes elastic deformation under the pressure of the locking block 81. The return spring 9 is used to help fix the locking block 81 to one side of the limiting block 32. Then the locking block 81 leaves the surface of the limiting block 32, thereby pulling the pressure block 6. Since the rotating block 5 is fixedly connected to the pressure block 6, the rotating block 5 rotates around the first rotating shaft 4 under the drive of the pressure block 6. At this time, the pressure block 6 separates from the positioning block 2, and then the connecting block 101 is taken out from the positioning block 2. The connecting block 202 is fixed on the outside of the steel mesh, thereby achieving quick connection of the steel mesh and improving the connection stability between the inner wall and the steel mesh.
[0053] The connecting column 1 is composed of various materials with different properties. The outermost layer of the connecting column 1 is a surface wear-resistant layer 11, which is made of alumina ceramic. This reduces the wear rate of the surface wear-resistant layer 11 and extends its service life. Subsequently, an anti-corrosion transition layer 12 is installed inside the surface wear-resistant layer 11. The anti-corrosion transition layer 12 is made of polytetrafluoroethylene coating. This allows the anti-corrosion transition layer 12 to shield external corrosive media and prevent corrosive agents from penetrating from the interlayer interface, protecting the inner layer material from corrosion. Then, a tough buffer layer 13 is installed inside the anti-corrosion transition layer 12. This allows the tough buffer layer 13 to reduce the direct effect of rigid impact on the core bearing layer 14. The innermost layer of the connecting column 1 is the core bearing layer 14, which is made of titanium alloy. This allows the core bearing layer 14 to withstand alternating stress for a long time. This achieves improved wear resistance, corrosion resistance, dynamic load buffering, and high strength bearing performance, reduces the failure risk caused by single material performance defects, enhances comprehensive performance and environmental adaptability, and reduces maintenance costs.
