Technical Field

[0001] The utility model relates to the technical field of connecting pieces, in particular to a fastening structure. Background Art

[0002] At present, the material of existing screws is mostly carbon steel, on this basis, a surface hardening process is added. During use, most of the tools are pneumatic screwdrivers. When twisting, the pneumatic screwdriver is prone to act on the surface of the screw to form sharp corners, and users are easily injured when they come into contact with it. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0004] In view of this, an embodiment of the present invention provides a fastening structure.

[0005] In order to achieve the above-mentioned purpose, an embodiment of the first aspect of the utility model provides a fastening structure, including: a threaded column; a connecting platform, arranged at one end of the threaded column; a connecting groove, arranged on the connecting platform; a sink groove, arranged at the bottom of the connecting groove; wherein the shape of the sink groove is adapted to the shape of the connecting groove, and there is a gap between the groove wall of the sink groove and the groove wall of the connecting groove.

[0006] The fastening structure proposed by the utility model includes a threaded column, a connecting platform, a connecting groove and a sink groove, wherein the threaded column is the core of the fastening structure, and its main function is to achieve connection and fastening through threads and matching nuts or prefabricated threaded holes. The threaded column can provide strong tensile and torsional strength to ensure the stability and reliability of the fastening structure when subjected to force.

[0007] The connection platform is located at one end of the threaded column. Through the connection platform, the fastener can be more stably combined with other components, and it also provides space and foundation for the design of the connection groove. The connection groove is designed on the connection platform. The existence of the connection groove greatly increases the application scope and flexibility of the fastening structure, enabling it to adapt to a variety of accessories of different shapes and sizes, thereby improving the versatility of the overall structure.

[0008] The core purpose of the groove design is to improve safety during use. By creating a sunken step surface, any burrs or sharp corners caused by the interaction between the tool and the screw head during the tightening process will be confined to the sunken area and away from the direct contact surface of the user.

[0009] The sinking groove effectively limits the potential sharp burrs to the sunken steps that users cannot touch, greatly reducing the risk of scratches or cuts that may occur during use. In addition, it not only provides protection from a safety perspective, but also visually avoids the appearance of defects such as burrs, keeping the product neat and beautiful.

[0010] It can be understood that the recessed grooves designed in the fastening structure can allow for slight errors in the assembly process to a certain extent, because some slight deformations caused by the assembly force can be accommodated by the recessed grooves, thereby not affecting the overall appearance and function.

[0011] In some technical solutions, optionally, the connecting groove includes a first groove and a second groove that are perpendicular to each other, and the length of the first groove is greater than the length of the second groove.

[0012] In this technical solution, the connection groove has two mutually perpendicular grooves, namely the first groove and the second groove, wherein the length of the first groove is greater than the length of the second groove. By setting two perpendicular grooves, connection points in multiple directions can be provided, so that the fastening structure can be connected to components in multiple different directions. The first groove and the second groove have different lengths, providing connection spaces of different sizes, which can adapt to accessories of different sizes and shapes.

[0013] This design allows the fastening structure to be connected to different components in multiple directions, increasing its applicability in various application scenarios.

[0014] The design of this connecting groove not only improves the versatility and adaptability of the fastening structure but also enhances its stability and practicality by introducing two grooves that are perpendicular to each other and have different lengths.

[0015] In some technical solutions, optionally, the sinking groove includes a third groove and a fourth groove which are perpendicular to each other, the third groove is located in the first groove, and the fourth groove is located in the second groove.

[0016] In this technical solution, the sink groove is refined to include a third groove and a fourth groove that are perpendicular to each other, wherein the third groove is located inside the first groove, and the fourth groove is located inside the second groove. By designing the third groove and the fourth groove inside the first groove and the second groove, respectively, more connection points can be provided, thereby improving the connection capacity of the fastening structure.

[0017] The vertical third and fourth grooves can provide directional connection points for a specific connection direction, so that the fastening structure can be more accurately adapted to a specific component. The design of multiple vertical grooves allows the fastening structure to adapt to more types of connection requirements and provide higher flexibility.

[0018] The design of this sink groove not only improves the versatility and adaptability of the fastening structure, but also enhances its stability and practicality by adding vertical third and fourth grooves inside the connecting groove.

[0019] In some technical solutions, optionally, the length of the third groove is the same as the length of the fourth groove; or the length of the third groove is greater than the length of the fourth groove.

[0020] In this technical solution, the length of the third groove is the same as that of the fourth groove, providing symmetrical connection points, so that the fastening structure has the same connection capacity in all directions.

[0021] The length of the third groove is greater than that of the fourth groove, allowing the third groove to provide a longer contact area or a deeper embedding space, which may be used to accommodate longer or more complex connection parts. A longer third groove can provide a stronger fixing force, which is suitable for connection requirements that require greater fastening force or deeper embedding.

[0022] In some technical solutions, optionally, it also includes: a baffle structure, which is arranged on the connecting platform, and the baffle structure is arranged along the edge of the connecting groove.

[0023] In this technical solution, the baffle structure is arranged along the edge of the connection groove, which can effectively prevent the user from contacting the spikes or sharp edges inside the connection groove. As a physical barrier, the baffle structure can reduce the risk of injury to the user when using the fastening structure, thereby improving the safety of the product.

[0024] In some technical solutions, optionally, it also includes: an anti-slip coating provided on the end surface of the connecting platform.

[0025] In this technical solution, the anti-slip coating can increase the friction coefficient of the end surface of the connection platform, thereby improving the stability and safety when grasping. When using the fastening structure, the anti-slip coating can reduce accidental loosening or rotation caused by hand slippage.

[0026] It can be understood that the application of anti-slip coating on the end surface of the connection table of the fastening structure provides additional safety and convenience for the operator. This design not only improves the safety and durability of the product, but also improves the user experience, making the fastening structure more ergonomic and practical.

[0027] In some technical solutions, optionally, it also includes: a protective sleeve, which is sleeved on the connecting platform.

[0028] In this technical solution, by providing a protective cover, the protective cover can protect the connection platform from external environmental erosion, such as dust, moisture, chemicals, etc., and extend the service life of the connection platform. The protective cover can prevent the user from contacting the sharp edges or spikes of the connection platform during operation, reducing the risk of injury. The protective cover usually has good elasticity and softness, which can provide a more comfortable grip and make the operation more stable. The protective cover can improve the appearance of the fastening structure and enhance the visual appeal of the product through different colors and shapes.

[0029] Of course, the protective cover can provide a certain buffering effect when subjected to shock or vibration, protecting the connection platform from damage. The addition of the protective cover provides an additional layer of protection for the fastening structure, which not only improves the safety and durability of the product, but also improves the user's operating experience and the appearance of the product.

[0030] In some technical solutions, optionally, it also includes: a boss structure, which is arranged on the end surface of the connecting platform; wherein the side wall of the boss structure is a curved surface.

[0031] In this technical solution, a boss structure is provided on the end face of the connecting platform. In this case, the curved side wall can reduce sharp edges and reduce the risk of scratches for users during use.

[0032] In addition, the boss structure can serve as a protective portion of the connecting platform to reduce direct wear on the connecting platform.

[0033] In some technical solutions, optionally, the diameter of the threaded column remains unchanged in the direction from the connecting platform to the threaded column; or the diameter of at least part of the threaded column gradually decreases in the direction from the connecting platform to the threaded column.

[0034] In this technical solution, the use of a threaded column with a constant diameter helps to standardize the production process and simplify the manufacturing process. Maintaining a consistent diameter can ensure that the threaded column provides uniform connection strength over the entire length.

[0035] Alternatively, by using a threaded column with a tapered diameter, you can adapt to different torque requirements and optimize the tightening force. The tapered diameter helps to more evenly distribute the stress generated during tightening. The tapered diameter allows for more precise tightening control to avoid over-tightening or over-loosening.

[0036] During the tightening process, the gradually decreasing diameter can reduce thread wear and extend service life.

[0037] Whether it is to keep the thread column diameter unchanged or design it to a gradually decreasing diameter, each design has its specific application scenarios and advantages. The constant diameter helps to standardize production and ensure the consistency of the connection, while the gradually decreasing diameter provides more design flexibility and the possibility of optimizing fastening performance. Users can choose according to specific application requirements and performance goals.

[0038] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0048] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0050] Refer to the following Figures 1 to 7 Some embodiments according to the present invention are described.

[0051] like Figure 1As shown, a fastening structure 100 proposed in this embodiment includes a threaded column 102, a connecting platform 104, a connecting groove 106 and a sink 108, wherein the threaded column 102 is the core of the fastening structure 100, and its main function is to achieve connection and fastening through threads and matching nuts or prefabricated threaded holes. The threaded column 102 can provide strong tensile and torsional strength to ensure the stability and reliability of the fastening structure 100 when subjected to force.

[0052] The connection platform 104 is located at one end of the threaded column 102. Through the connection platform 104, the fastener can be more stably combined with other components, and also provides space and foundation for the design of the connection groove 106. The connection groove 106 is designed on the connection platform 104. The existence of the connection groove 106 greatly increases the application scope and flexibility of the fastening structure 100, so that it can adapt to a variety of accessories of different shapes and sizes, thereby improving the versatility of the overall structure.

[0053] The core purpose of the design of the sink 108 is to improve safety during use. By creating a sunken step surface, any burrs or sharp corners generated by the interaction between the tool and the screw head during the tightening process will be confined to the sunken area, away from the user's direct contact surface. This solution provides a new structure, adding a sunken step, and there is a step difference between the end surface of the connecting platform 104 and the surface of the sink 108. The burrs squeezed out by the air screwdriver head are lower than the hand contact surface, solving the problem of scratching the hand.

[0054] Specific as Figure 7 As shown, the force application point B between the fastening structure 100 and the air screwdriver is lower than the finger contact surface A. Even if the application point is squeezed and burrs or sharp corners appear, the finger cannot touch it, and there is no safety risk.

[0055] Under the action of the sink 108, the potential sharp burrs are effectively confined to the sunken steps that the user cannot touch, greatly reducing the risk of scratches or cuts that may occur during use. In addition, it not only provides protection from a safety perspective, but also visually avoids the appearance of defects such as burrs, keeping the product neat and beautiful.

[0056] It can be understood that the design of the recessed groove 108 in the fastening structure 100 can allow slight errors in the assembly process to a certain extent, because some slight deformations caused by the assembly force can be accommodated by the recessed groove 108, thereby not affecting the overall appearance and function.

[0057] In some embodiments, optionally, Figure 2As shown, the connection groove 106 has two mutually perpendicular grooves, namely a first groove 1062 and a second groove 1064, wherein the length of the first groove 1062 is greater than the length of the second groove 1064. By providing two perpendicular grooves, connection points in multiple directions can be provided, so that the fastening structure 100 can be connected to components in multiple different directions. The first groove 1062 and the second groove 1064 have different lengths, providing connection spaces of different sizes, which can adapt to accessories of different sizes and shapes.

[0058] This design allows the fastening structure 100 to be connected to different components in multiple directions, thereby increasing its applicability in various application scenarios.

[0059] The design of the connecting groove 106 not only improves the versatility and adaptability of the fastening structure 100 but also enhances its stability and practicality by introducing two grooves that are perpendicular to each other and have different lengths.

[0060] It should be added that the first groove 1062 and the second groove 1064 form a cross groove structure, which can accommodate both a flat head screwdriver and a cross head screwdriver.

[0061] In some embodiments, the sink groove 108 is optionally refined to include a third groove 1082 and a fourth groove 1084 that are perpendicular to each other, wherein the third groove 1082 is located inside the first groove 1062, and the fourth groove 1084 is located inside the second groove 1064. By respectively designing the third groove 1082 and the fourth groove 1084 inside the first groove 1062 and the second groove 1064, more connection points can be provided, thereby improving the connection capability of the fastening structure 100.

[0062] The vertical third slot 1082 and the fourth slot 1084 can provide directional connection points for a specific connection direction, so that the fastening structure 100 can be more accurately adapted to a specific component. The design of multiple vertical slots allows the fastening structure 100 to adapt to more types of connection requirements and provide higher flexibility.

[0063] The design of the sink groove 108 not only improves the versatility and adaptability of the fastening structure 100 but also enhances its stability and practicality by adding a vertical third groove 1082 and a fourth groove 1084 inside the connecting groove 106 .

[0064] In a specific embodiment, the length of the third groove 1082 is the same as the length of the fourth groove 1084 , providing symmetrical connection points, so that the fastening structure 100 has the same connection capability in all directions.

[0065] In another specific embodiment, the length of the third groove 1082 is greater than the length of the fourth groove 1084, allowing the third groove 1082 to provide a longer contact area or a deeper embedding space, which may be used to accommodate longer or more complex connection components. The longer third groove 1082 can provide a stronger fixing force, which is suitable for connection requirements that require greater fastening force or deeper embedding.

[0066] In a specific embodiment, optionally, Figure 3 As shown, a baffle structure 110 is provided, specifically along the edge of the connection slot 106, which can effectively prevent the user from contacting the spikes or sharp edges inside the connection slot 106. As a physical barrier, the baffle structure 110 can reduce the risk of injury to the user when using the fastening structure 100, thereby improving the safety of the product.

[0067] In a specific embodiment, optionally, Figure 4 As shown, the anti-skid coating 112 can increase the friction coefficient of the end surface of the connection platform 104, thereby improving the stability and safety during gripping. When the fastening structure 100 is used, the anti-skid coating 112 can reduce accidental loosening or rotation caused by hand slippage.

[0068] It can be understood that the application of the anti-slip coating 112 on the end surface of the connecting platform 104 of the fastening structure 100 provides additional safety and convenience for the operator. This design not only improves the safety and durability of the product, but also improves the user experience, making the fastening structure 100 more ergonomic and practical.

[0069] In a specific embodiment, optionally, Figure 5 As shown, a protective cover 114 is provided, which can protect the connection platform 104 from erosion by the external environment, such as dust, moisture, chemicals, etc., and extend the service life of the connection platform 104. The protective cover 114 can prevent the user from contacting the sharp edges or spikes of the connection platform 104 during operation, reducing the risk of injury. The protective cover 114 usually has good elasticity and softness, and can provide a more comfortable grip and make the operation more stable. The protective cover 114 can improve the appearance of the fastening structure 100 and enhance the visual appeal of the product through different colors and shapes.

[0070] Of course, when subjected to shock or vibration, the protective cover 114 can provide a certain buffering effect to protect the connection platform 104 from damage. The addition of the protective cover 114 provides an additional layer of protection for the fastening structure 100, which not only improves the safety and durability of the product, but also improves the user's operating experience and the appearance of the product.

[0071] In some embodiments, optionally, Figure 6As shown, a boss structure 116 is provided on the end surface of the connecting platform 104. In this case, the curved side wall can reduce sharp edges and reduce the risk of scratches to users during use.

[0072] In addition, the boss structure 116 can serve as a protective portion of the connecting platform 104 to reduce direct wear on the connecting platform 104 .

[0073] In some embodiments, optionally, using a threaded column 102 with a constant diameter helps to standardize the production process and simplify the manufacturing process. Maintaining a consistent diameter can ensure that the threaded column 102 provides uniform connection strength over the entire length.

[0074] In some embodiments, optionally, a threaded column 102 with a gradually decreasing diameter can be used to adapt to different torque requirements and optimize the tightening force. The gradually decreasing diameter helps to more evenly distribute the stress generated during tightening. The gradually decreasing diameter helps to achieve more precise tightening control and avoid over-tightening or over-loosening.

[0075] During the tightening process, the gradually decreasing diameter can reduce thread wear and extend service life.

[0076] Whether it is to keep the threaded column 102 diameter unchanged or design it to a gradually decreasing diameter, each design has its specific application scenarios and advantages. The constant diameter helps to standardize production and ensure the consistency of the connection, while the gradually decreasing diameter provides more design flexibility and the possibility of optimizing fastening performance. Users can choose according to specific application requirements and performance goals.
