Pneumatic Nail Gun Asymmetric Buckled Ring Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional C-type nail guns are unsuitable for weight-bearing applications due to deformation of buckled rings with aligned ends, leading to potential dislodgment of construction materials, and they cannot efficiently form buckled rings with crossing ends, resulting in low operation efficiency and discontinuous nail discharge.
Innovation Solution
A pneumatic nail gun with a gun body, nail box, fork, and nail forming device that uses a sliding groove, push block, and forming surfaces of unequal heights to form buckled rings with crossing ends by staggering the ends of strip nails, allowing continuous nail discharge without vertical displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If buckled rings with aligned ends are formed by conventional C-type nail gun, then binding operation of construction materials can be completed, but the buckled rings are prone to deforming under weight causing closure failure and potential dislodgment
Solution Approach 1:
The patent applies asymmetry by forming buckled rings with crossing ends instead of aligned ends. The nail is bent at an angle (not 180 degrees) to create crossing ends that interlock, providing asymmetric geometry that prevents deformation and enhances weight-bearing capability while maintaining binding functionality
2Reliability
If buckled rings with crossing ends are formed, then weight bearing capability is improved, but the nail box cannot continuously discharge nails due to vertical displacement during forming
Solution Approach 1:
The patent resolves the vertical displacement issue by introducing horizontal movement through a sliding groove mechanism. The forming device moves horizontally along the sliding groove during nail formation, converting the problematic vertical displacement into controlled horizontal motion, thereby enabling continuous nail discharge while maintaining crossing end formation
3Ease of operation
If conventional C-type nail gun forms buckled rings, then operation can proceed, but vertical displacement during forming disrupts normal nail box operation
Solution Approach 1:
The patent introduces a sliding groove as an intermediary mechanism between the forming device and the nail box. This sliding groove mediates the motion during nail formation, allowing the forming device to move horizontally while maintaining proper positioning relative to the nail supply, thus enabling both easy operation and continuous efficient nail discharge

AI summary
The invention provides a pneumatic nail gun, comprising a gun body, a nail box, a fork and a nail forming device. The gun body comprises a sliding groove, a nail outlet adjacent to the sliding groove and a push block. The nail box and the fork are fixed on the gun body. The nail box is configured to place a plurality of strip nails to be sequentially exposed from the nail outlet. The formed fork comprises two forming surfaces with unequal heights, and the two forming surfaces are adjacent to the nail outlet. The nail forming device comprises two jaw arms, two control arms and a push seat, and the push block drives the two control arms to drive the two jaw arms to rotate and close the two forming jaws, and to drive the push seat to slide on the sliding groove.
