Spring-Guided High-Nut Bolt Connector for Misalignment Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting long bolts in wooden housing often result in misaligned bolt centers, making it difficult to insert bolts into high nuts, especially when using bolts of large diameters, and require laborious axial movement of double nuts for locking, which is inefficient.
Innovation Solution
A bolt connector featuring a high nut with a female screw portion and a spring inserted into it, where the spring contacts the bolt's threads, guiding the bolt and reducing misalignment, allowing easy insertion and locking without rotating the nut, and providing enhanced joining strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If a high nut is used to connect long bolts through upper and lower beams, then the bolts can be connected vertically, but the bolt centers become misaligned making insertion difficult
Solution Approach 1:
A guide member is introduced as an intermediary component between the high nut and the bolt. This guide member extends from the high nut toward the bolt, providing a physical guide that aligns the bolt center with the high nut center during insertion. The guide member acts as a mediator that resolves the misalignment issue without requiring changes to the fundamental high nut connection method.
Solution Approach 2:
The guide member is pre-positioned on the high nut before bolt insertion occurs. By establishing the alignment path in advance through the guide member, the system prepares the connection interface beforehand, ensuring that when the bolt is inserted, it follows the predetermined alignment path and reaches the correct position without misalignment.
2Reliability
If a double nut is used to prevent loosening through shear force locking, then the connection becomes secure, but the device complexity and labor increase due to axial movement requirements
Solution Approach 1:
The locking function is extracted from the nut structure itself and separated into a dedicated guide member with locking protrusions. Instead of using a complex double nut system where one nut locks the other through axial movement, the guide member provides the locking function independently through its geometric shape and engagement features, simplifying the overall device structure.
Solution Approach 2:
The guide member with its specific geometric shape automatically provides locking functionality as the bolt is inserted and tightened. The locking protrusions on the guide member engage with corresponding features on the bolt or high nut, creating a self-locking mechanism that prevents loosening without requiring additional axial movement operations or complex double nut assemblies.

AI summary
An object of the present invention is to provide a bolt connector that enables a bolt to be inserted into a high nut, and is capable of easily maintaining a connection state between the bolt and the nut. The bolt connector connects two bolts and is configured by: a high nut that has a female screw portion; and a spring that is partially inserted into the female screw portion. The female screw portion is formed having a larger diameter than an outer diameter of the bolt. The spring is formed into a shape in which the spring is in contact with threads of the female screw portion and a male screw portion of the bolt, in a state in which the bolt or the high nut is rotated and fastened.
