Description

Technical Field

[0001] This application relates to the field of hoisting tools, and in particular to a screw assembly for hoisting timber structures. Background Technology

[0002] In the hoisting of wooden structures, traditional hoisting methods usually use simple tools such as ropes and steel wires. These methods are not only inconvenient to operate, but also have low safety.

[0003] To address these issues, some fasteners specifically designed for hoisting wooden structures have emerged on the market. However, these fasteners generally suffer from problems such as complex structure, inconvenient installation, and limited load-bearing capacity.

[0004] Therefore, how to design a screw assembly for hoisting wooden structures that is simple in structure, easy to install, and has a strong load-bearing capacity has become an urgent problem to be solved. Utility Model Content

[0005] To help solve the technical problem of simple and efficient installation of hoisting equipment, this application provides a bolt assembly for hoisting timber structures, adopting the following technical solution:

[0006] A screw assembly for hoisting wooden structures includes a self-tapping screw, an eye bolt, and an external hexagonal connector. The self-tapping screw has a connected screw portion and a threaded tip. One end of the external hexagonal connector is fixedly connected to the end of the screw portion of the self-tapping screw away from the threaded tip, and the other end is provided with a first threaded hole for installing the eye bolt.

[0007] By adopting the above technical solution, using a combination structure of self-tapping screw and external hexagonal connector, when self-tapping on the wooden structure, the external hexagonal connector is driven to rotate, thereby driving the self-tapping screw to rotate and tap the thread. This makes it easy to tap threads on the wooden structure, and the external hexagonal connector is connected to the eye bolt, thus achieving a fast and stable hoisting connection and improving work efficiency.

[0008] Optionally, the self-tapping screw further includes a guide section extending coaxially from the screw portion away from the thread tip, a limiting platform protruding circumferentially from the guide section, and an external thread connecting the limiting platform away from the guide section. The external thread is threadedly connected to the external hexagonal connector, and the side of the limiting platform away from the thread tip abuts against the external hexagonal connector.

[0009] By adopting the above technical solution, the external hexagonal connector is connected to the external thread, and the limiting platform abuts against the external hexagonal connector, which improves the reliability of the connection between the self-tapping screw and the external hexagonal connector. The guide section is connected to the screw section, which helps to ensure the depth of the screw section into the wooden structure. When hoisting the wooden structure, it helps to improve the reliability of the connection between the external hexagonal connector and the self-tapping screw, thereby improving the safety of hoisting.

[0010] Optionally, the external hexagonal connector further includes a second threaded hole at the end away from the first threaded hole, the second threaded hole being used to install the connecting external thread.

[0011] By adopting the above technical solution, the first threaded hole of the external hexagonal connector is used to install the eye screw, and the second threaded hole is used to install the connecting external thread, which facilitates the assembly of the self-tapping screw, the external hexagonal connector and the eye screw, and helps to improve the ease of use.

[0012] Optionally, the second threaded hole is coaxially connected to the first threaded hole.

[0013] By adopting the above technical solution, the second threaded hole, which is coaxially connected, facilitates processing and manufacturing. At the same time, the eye screw can be easily installed on the other end of the external hexagonal connector, thereby realizing the quick connection between the self-tapping screw and the eye screw, which is convenient for lifting wooden structures with the same self-tapping screw direction and lifting direction.

[0014] Optionally, a limiting hole for axially limiting the self-tapping screw is provided at the same end of the second threaded hole. The limiting hole is coaxially arranged with the second threaded hole, and the diameter of the limiting hole is larger than the diameter of the second threaded hole. A limiting surface is formed between the limiting hole and the first threaded hole, and the limiting platform abuts against the limiting surface.

[0015] By adopting the above technical solution, the limiting platform abuts against the limiting surface, which improves the reliability of the connection between the self-tapping screw and the external hexagonal connector, thereby improving the safety of hoisting.

[0016] Optionally, the external hexagonal connector further includes a third threaded hole, wherein the third threaded hole is disposed on any hexagonal face of the external hexagonal connector, and the third threaded hole is threadedly connected to the eye bolt.

[0017] By adopting the above technical solution, the eye bolt can be installed in either the first threaded hole or the third threaded hole, depending on the installation position of the lifting bolt assembly, thereby improving the applicability and flexibility of the bolt assembly.

[0018] Optionally, the first threaded hole of the external hexagonal connector is located on any hexagonal face of the external hexagonal connector.

[0019] By adopting the above technical solution, when hoisting a wooden structure with the self-tapping screw direction perpendicular to the hoisting direction, installing a lifting eye screw on the first threaded hole on the hexagonal face of the external hexagonal connector can facilitate hoisting.

[0020] Optionally, the hardness of the self-tapping screw is HRC32 to 39.

[0021] By adopting the above technical solution, the moderate hardness range ensures that the self-tapping screw has good cutting performance, while avoiding the risk of breakage due to excessive hardness during hoisting, thus ensuring the safety and durability of the screw assembly during use.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The combination structure of self-tapping screw and external hexagonal connector is adopted. When self-tapping on the wooden structure, the external hexagonal connector is driven to rotate, thereby driving the self-tapping screw to rotate and tap. It can easily tap the thread on the wooden structure. The external hexagonal connector is connected to the eye bolt, thus realizing a fast and stable hoisting connection and improving work efficiency.

[0024] 2. The guide section is connected to the screw rod, which helps to ensure the depth of the screw rod into the wooden structure. When hoisting the wooden structure, it helps to improve the reliability of the connection between the external hexagonal connector and the self-tapping screw rod, thereby improving the safety of hoisting.

[0025] 3. The first threaded hole of the external hexagonal connector is used to install the eye bolt, and the second threaded hole is used to install the external thread, which facilitates the assembly of the self-tapping screw, the external hexagonal connector and the eye bolt, and helps to improve the ease of use;

[0026] 4. The second threaded hole, which is coaxially connected, facilitates processing and manufacturing. At the same time, the eye screw can be easily installed on the other end of the external hexagonal connector, thereby realizing the quick connection between the self-tapping screw and the eye screw, which is convenient for lifting wooden structures with the same self-tapping screw direction and lifting direction.

[0027] 5. The limiting platform abuts against the limiting surface, which improves the reliability of the connection between the self-tapping screw and the external hexagonal connector, thereby improving the safety of hoisting;

[0028] 6. The eye bolt can be installed in either the first or third threaded hole, depending on the installation position of the lifting bolt assembly, thereby improving the applicability and flexibility of the bolt assembly.

[0029] 7. When hoisting a wooden structure with the self-tapping screw direction perpendicular to the hoisting direction, install a lifting eye bolt on the first threaded hole on the hexagonal face of the external hexagonal connector to facilitate hoisting.

[0030] 8. The moderate hardness range ensures that the self-tapping screw has good cutting performance, while avoiding the risk of breakage due to excessive hardness during hoisting, thus ensuring the safety and durability of the screw assembly during use. Attached Figure Description

[0039] The following combination Figures 1 to 6 This application will be described in further detail.

[0040] Example 1

[0041] This embodiment discloses a screw assembly for hoisting wooden structures. (Refer to...) Figure 1The system includes a self-tapping screw 1, an eye screw 2, and an external hexagonal connector 3. The self-tapping screw 1 includes a screw section 11 and a threaded tip 12 connected together. In this embodiment, one end of the external hexagonal connector 3 is fixedly connected to the screw section 11 of the self-tapping screw 1 by a thread. In other embodiments, the external hexagonal connector 3 and the screw section 11 of the self-tapping screw 1 can be integrally formed. The other end is provided with a first threaded hole 31 for installing the eye screw 2. By adopting the combined structure of the self-tapping screw 1 and the external hexagonal connector 3, when self-tapping on the wooden structure, the external hexagonal connector 3 is driven to rotate, thereby driving the self-tapping screw 1 to rotate and tap. This allows for easy tapping of threads on the wooden structure and embedding into the wooden structure. The external hexagonal connector 3 is connected to the eye screw 2, thereby achieving a fast and stable lifting connection and improving work efficiency.

[0042] Reference Figure 2 The self-tapping screw 1 also includes a guide section 111 extending coaxially from the screw portion 11 away from the thread tip 12, a limiting platform 112 protruding circumferentially from the guide section 111, and a connecting external thread 113 connecting the limiting platform 112 away from the guide section 111. The connecting external thread 113 is threadedly connected to the external hexagonal connector 3. The side of the limiting platform 112 away from the thread tip 12 abuts against the external hexagonal connector 3. The external hexagonal connector 3 is threadedly connected to the connecting external thread 113. The abutment between the limiting platform 112 and the external hexagonal connector 3 improves the reliability of the connection between the self-tapping screw 1 and the external hexagonal connector 3. The connection between the guide section 111 and the screw portion 11 helps to ensure the depth of the screw portion 11 into the wooden structure. When hoisting the wooden structure, it helps to improve the reliability of the connection between the external hexagonal connector 3 and the self-tapping screw 1, thereby improving the safety of hoisting.

[0043] Reference Figure 3 The external hexagonal connector 3 also includes a second threaded hole 32 at the end away from the first threaded hole 31. The second threaded hole 32 is used to install the connecting external thread 113. The first threaded hole 31 of the external hexagonal connector 3 is used to install the eye screw 2, and the second threaded hole 32 is used to install the connecting external thread 113. This facilitates the assembly of the self-tapping screw 1, the external hexagonal connector 3 and the eye screw 2, and helps to improve the ease of use.

[0044] Reference Figure 3 The second threaded hole 32 is coaxially connected to the first threaded hole 31. The coaxial connection of the second threaded hole 32 facilitates processing and manufacturing. At the same time, the eye screw 2 can be easily installed on the other end of the external hexagonal connector 3, thereby realizing the quick connection between the self-tapping screw 1 and the eye screw 2, which facilitates the lifting of wooden structures with the same self-tapping screw direction and lifting direction.

[0045] Reference Figure 3A limiting hole 33 is provided at the same end of the second threaded hole 32 for axially limiting the self-tapping screw 1. The limiting hole 33 is coaxially arranged with the second threaded hole 32. The diameter of the limiting hole 33 is larger than the diameter of the second threaded hole 32. A limiting surface 331 is formed between the limiting hole 33 and the first threaded hole 31. The limiting platform 112 abuts against the limiting surface 331. The connection between the limiting platform 112 and the limiting surface 331 improves the reliability of the connection between the self-tapping screw 1 and the external hexagonal connector 3, thereby improving the safety of hoisting.

[0046] Reference Figure 4 The external hexagonal connector 3 also includes a third threaded hole 34. The internal threaded hole is provided on any hexagonal surface of the external hexagonal connector 3. The third threaded hole 34 is threadedly connected to the eye bolt 2. The eye bolt 2 can be installed in the first threaded hole 31 or the third threaded hole 34, depending on the installation position of the lifting screw assembly, thereby improving the applicability and flexibility of the screw assembly.

[0047] The self-tapping screw 1 has a hardness of HRC32-39. This moderate hardness range ensures that the self-tapping screw 1 has good cutting performance, while avoiding the risk of breakage due to excessive hardness during hoisting, thus ensuring the safety and durability of the screw assembly during use.

[0048] Example 2

[0049] Reference Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that the first threaded hole 31 of the external hexagonal connector 3 is set on any hexagonal face of the external hexagonal connector 3. When the direction of the self-tapping screw is perpendicular to the direction of the hoisting of the wooden structure, the eye bolt 2 is installed on the first threaded hole 31 on the hexagonal face of the external hexagonal connector 3, which can facilitate hoisting. In this embodiment, the external hexagonal connector 3 and the self-tapping screw 1 are integrally formed. In other embodiments, the external hexagonal connector 3 and the self-tapping screw 1 can also be detachably fixedly connected.

[0050] The working principle of a screw assembly for hoisting a wooden structure is as follows: assemble the self-tapping screw 1 with the external hexagonal connector 3, insert the external hexagonal connector 3 into the drive head of an electric wrench, self-tapping the screws at different hoisting positions of the wooden structure to be hoisted, install eye bolts 2 on the external hexagonal connector 3, and thread hoisting straps through the eye bolts 2 at different hoisting positions. The hoisting equipment lifts the wooden structure through the hoisting straps and the screw assembly.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
