Description

Technical Field

[0001] This utility model belongs to the field of machine equipment installation technology, specifically relating to a dual-purpose quick-fastening screw. Background Technology

[0002] In modern engineering construction and equipment installation, fastening screws are indispensable basic connection tools. Different engineering projects and equipment require the use of different specifications of fastening screws, especially in some more complex construction sites, where it is often necessary to frequently switch between different specifications of screws (such as M12 and M16 screws) to complete the installation task. Currently, most fastening screws on the market are designed for a single specification, requiring users to carry multiple specifications of screws in actual operation, increasing the difficulty of carrying and managing them, as well as increasing procurement and storage costs.

[0003] Furthermore, because screws require a certain amount of force to tighten, traditional screws often lack user-friendly design features, leading to inconvenience and inefficiency during the tightening process. This is especially true in harsh construction conditions or confined spaces, where operator efficiency can be significantly affected. Therefore, there is an urgent need for a screw design that can simultaneously meet multiple specification requirements, is portable, and easy to operate.

[0004] To address the above issues, this utility model proposes a dual-purpose quick-tightening screw. It features both M12 and M16 thread specifications on the same screw, employing a "one screw, two uses" design concept. This allows for flexible switching according to actual needs, reducing the operational burden on construction sites and saving on equipment procurement and management costs. Furthermore, a wrench clamping surface is milled in the middle of the screw, further enhancing operational convenience and ensuring efficient and safe screw tightening.

[0005] This utility model, through its innovative design, provides a more efficient, flexible, and convenient solution for screw applications in the engineering field.

[0006] Existing fastening screws (publication number: CN222163166U) have the following disadvantages:

[0007] 1. Single-size screw design: Currently, most fastening screws on the market are designed for a single size, requiring users to carry multiple sizes of screws depending on different project needs. This not only increases the difficulty of carrying and storing screws but also increases procurement and management costs. On-site, frequent changes to different sizes of screws can also affect work efficiency, so there is an urgent need for a dual-purpose fastening screw.

[0008] 2. Inconvenient tightening operation: Traditional fastening screw designs often fail to consider ease of operation, especially in confined spaces or harsh conditions at construction sites, where operators need considerable force to successfully complete the tightening work. The lack of specialized tool support design easily leads to inconvenience and low worker efficiency, thus necessitating a fastening screw with a tightening mechanism. Utility Model Content

[0024] Example

[0025] Please see Figure 1-2 This utility model provides a technical solution:

[0026] In this embodiment, a dual-purpose quick-fastening screw includes a dual-purpose screw 1, a pressure plate 2, and a clamping nut 3. The dual-purpose screw 1 is fitted into the clamping nut 3 and the pressure plate 2, and the pressure plate 2 is located at the rear end of the clamping nut 3.

[0027] The dual-purpose screw 1 has an M12 thread 101 at its front end and an M16 thread 104 at its rear end. The M16 thread 104 and the M12 thread 101 are each one-fifth of the length of the dual-purpose screw 1. The M16 thread 104 is connected to a quick-release thread 102 on its inner side. A wrench clamping position 103 is provided in the middle of the quick-release thread 102.

[0028] In this embodiment, the wrench clamping position 103 clamps the compression nut 3.

[0029] In this embodiment, the clamping nut 3 has protrusions on both sides, which can be used to tighten bolts.

[0030] This embodiment discloses a dual-purpose quick-fastening screw, mainly comprising a dual-purpose screw, a pressure plate, and a clamping nut. The design of this device optimizes the fastening process and improves the convenience and flexibility of operation. The specific structure and function are as follows:

[0031] Dual-purpose screw: The dual-purpose screw features an M12 thread at the front and an M16 thread at the rear. This dual thread design allows for flexible switching between different work scenarios, compatible with both M12 and M16 expansion bolts, thus achieving a "one-stop, two-use" function. This significantly reduces the number of tools required on-site, saving space and procurement costs. The screw's length is designed so that both the M16 and M12 threads each occupy one-fifth of the screw's length, ensuring sufficient length for tightening operations.

[0032] Quick-release threads: The M16 threaded section features quick-release threads on the inside, providing a more convenient assembly method. This design allows the bolt to be quickly connected to the screw, reducing operation time and labor intensity, making it particularly suitable for applications requiring frequent disassembly and assembly on construction sites. A wrench clamp is located in the center of the quick-release threads to help tighten the nut quickly and stably.

[0033] Wrench clamping position: The wrench clamping position is located in the middle of the quick-release thread to hold the nut in place. This design ensures that the nut is firmly secured during tightening, preventing loosening. The presence of the wrench clamping position improves operational stability, making the installation and removal of the nut safer and more reliable.

[0034] Compression Nut: Located at the rear end of the pressure plate, the compression nut works in conjunction with the dual-purpose screw and pressure plate to ensure that the components do not shift during bolt tightening and can withstand significant pressure without loosening. The compression nut has protruding portions on both sides, designed for use with tools during tightening. These protrusions allow operators to easily tighten the nut using a wrench or other tools, reducing the risk of tool slippage and improving tightening efficiency.

[0035] Pressure plate: Located at the rear end of the clamping nut, the pressure plate helps provide the necessary support force during tightening, ensuring a stable connection between the nut and the screw. It also effectively transmits the tightening force, preventing the device from loosening or being damaged due to uneven force distribution.

[0036] Usage process:

[0037] Preparation: At the construction site, first select the M12 or M16 size of the dual-purpose screw as needed. The quick-release threaded part can be installed as required. The dual-purpose screw can be connected to relevant components through quick-release threads, making it convenient to select the appropriate screw type.

[0038] Installation procedure: Insert the clamping nut into the corresponding part of the dual-purpose screw, ensuring that the nut and pressure plate are properly aligned. Use a wrench to clamp the wrench into the clamping nut to ensure the device is stable.

[0039] Tightening process: Operators can tighten the nut as needed by turning it. When tightening the nut, the protruding parts on both sides of the clamping nut provide additional gripping points, facilitating operation with tools such as wrenches. The dual-purpose screw design ensures the stability and firmness of the nut during tightening, preventing loosening or slippage due to improper operation.

[0040] Disassembly and Adjustment: When disassembly is required, the connection can be quickly released via the quick-release thread. Due to the dual-purpose screw design, operators can flexibly switch between M12 and M16 to adapt to different work requirements.

[0041] Through the above design, the dual-purpose quick-fastening screw in this embodiment not only provides higher efficiency and convenience in the fastening operation, but also makes the work on the construction site more efficient and safe, and effectively reduces the types of tools required, saving costs and management space.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
