Description

Technical Field

[0001] This utility model relates to the field of fastening components technology, and more specifically, to a novel nut. Background Technology

[0002] In the field of mechanical connections, the mating of nuts and screws is an extremely common and important connection method, widely used in the assembly of various mechanical equipment, building structures, and everyday items. Traditional nut structures are usually relatively simple, generally consisting of only a seat part that mates with the screw's threads. Its main function is to achieve a fastening connection with the screw through thread engagement.

[0003] However, these traditional nuts present numerous problems in practical use. One prominent issue is the phenomenon of screws passing through the nut. During assembly, due to operator negligence, unstable external forces, or inaccurate control of assembly force, screws often pass through the nut's intended mating position, resulting in over-holeing. This not only leads to loose connections, affecting the stability and reliability of mechanical structures, but can also cause safety accidents in severe cases. For example, in precision machinery requiring high connection accuracy, over-holeing can cause relative displacement between parts, thus affecting the overall performance of the equipment; in building structures, over-holeing can lead to insecure structural connections, reducing building safety. Utility Model Content

[0004] The main objective of this invention is to address the aforementioned defects and shortcomings by setting a flap structure to restrict the movement of the screw through the hole, thereby providing a novel nut.

[0005] To achieve the above objectives, the specific technical solution adopted by this utility model is as follows:

[0006] The present invention discloses a novel nut comprising a base and a flap structure. The base can be used to engage with a screw threadedly. The flap structure is connected to the base and is used to limit the screw from passing through the hole.

[0007] The valve structure includes a limiting arm that is inclined toward the axis of the seat; when the screw continues to move through the seat, it will be blocked by the limiting arm to prevent excessive thread engagement of the screw.

[0008] Preferably, the limiting arms are provided in at least one pair; or, multiple limiting arms are provided along the circumference of the seat.

[0009] Preferably, the limiting arm is configured as a prism-shaped structure.

[0010] Preferably, the plurality of limiting arms are arranged at intervals.

[0011] Preferably, the limiting arm and the seat body are provided with an integral reinforcing rib.

[0012] Preferably, the reinforcing rib is configured as two parallel strip structures.

[0013] Preferably, the valve structure further includes a limiting head, which is disposed at the end of the limiting arm to enhance the effect of preventing the screw from being punctured.

[0014] Preferably, the limiting head is configured as a fan-shaped structure.

[0015] Preferably, the base is provided with a threaded hole, which can be threaded with a screw.

[0016] Preferably, the base is cylindrical.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] In this utility model, the limiting arm in the valve structure is inclined toward the axis of the seat. When the screw continues to move through the seat, it will be blocked by the limiting arm, which effectively prevents the screw from being over-threaded and causing over-holeing. This ensures the stability of the connection between the nut and the screw and avoids the problem of loosening due to over-holeing. It is suitable for various mechanical and building structures with high requirements for connection accuracy and stability.

[0019] Building upon this, the valve structure also includes a limiting head located at the end of the limiting arm, further enhancing the screw's anti-through-hole effect and providing more reliable restriction on screw movement, ensuring the screw stops at the appropriate thread engagement position. When the screw head is configured with a sloped structure adapted to the limiting arm, the sloped wall of the screw head gradually engages with the inclined limiting arm. This design allows for a smoother contact process between the screw head and the limiting arm when the screw passes through the hole, providing a certain buffering effect and effectively preventing stripping and damage to the screw and nut caused by excessive external force, extending the service life of the nut and screw, and reducing maintenance costs.

[0020] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

The flap structure 20 includes a limiting arm 21, which is inclined toward the axis of the base 10.

At the same time, when the screw head is also configured to be a screw head with a slope structure that is adapted to the limiting arm 21, the slope wall of the screw head gradually fits into the inclined limiting arm 21, which has a certain buffering effect and prevents stripping and damage caused by excessive external force when the screw passes through the hole.
