Benefits of technology

This new technology uses an expandable type lock-ins for securely attaching doors or panels together without requiring any tools like bolts. It also allows for easier replacement with different sizes of latches that may have been damaged during maintenance work. Additionally, this design does not require excessive effort due to its lower costs compared to traditional methods such as weldings or rivets. Overall, these technical features improve efficiency and durability over existing systems used today.

Problems solved by technology

This patented technical problem addressed by this patents relates to conventional doors that use one layering fixation plating for secure attachment between two parts like an opening mechanism and a lock mechanism. However, these types of fixes have limitations due to their small contact area when they repeatedly open/close cycles over time causing wear and tear from repeated usage. Additionally, current methods require multiple steps during assembly which makes them difficult to maintain consistently at precise locations within each part's design.

Abstract

The invention relates to a connection structure of a door hinge fixing plate, which comprises an upper splint and a lower splint fixedly connected to each other, a fixed interlayer is arranged between the upper splint and the lower splint, and two clamping plates are mirror-symmetrically arranged in the fixed interlayer , the clamping plate is arc-shaped, one end of the clamping plate is clamped in the fixed interlayer, an opening is arranged in the middle of the lower clamping plate, and the other end of the clamping plate extends to the outside of the fixed interlayer through the opening; There is an expansion screw threaded in the middle of the upper splint, and an expansion column is arranged between the clamping plates. The expansion column is cylindrical, and its side wall is in contact with the inner side wall of the clamping plate. The surface is set in several conical positioning holes, the axis of the positioning holes is located on the radial axis of the expansion column, and the end of the expansion screw is tapered, contacting the positioning holes of the expansion block.
