Abstract

A concealed fastening structure for digital X-ray detector is proposed. As depicted in Figure 1, the structure includes a slot on a back cover of the detector and several clamping parts fixed in the slot. On a front window of the detector, an adhesion frame is attached and a rivet is held inside the holes in the adhesion frame. During assembly, after all internal parts of the detector are fitted inside the back cover, and the front window is covered with all rivet pins inserted into the clamping slots. Appropriate force is applied to push towards the front window to lock and fix the pin in position. After the rivet pins are inserted, a steel balls clamp a groove ring on each rivet pin to prevent the pin from unlocking.

A CONCEALED FASTENING STRUCTURE FOR A DIGITAL X-RAY DETECTOR

BACKGROUND

 

The present disclosure relates generally to X-ray imaging systems and more particularly to a concealed fastening structure for a digital X-ray detector.

Generally, digital X-ray detectors require fasteners to fixed parts of the detector together. Using fasteners on external surface of detector poses various challenges. One challenge is biocompatibility. Out of the various biocompatible materials, stainless steel is mostly used because aluminum alloy fasteners lack the required strength and carbon steel fasteners lack corrosion resistance. However, commonly used stainless steel fasteners typically fail the biocompatibility test.

Another challenge is cleaning. Applying fasteners results in several holes and slots. It is difficult to clean such small holes and slots during operation. Also, cleaning liquids tend to collect in the holes and cause corrosion. Yet another challenge is aesthetics. Fasteners are not aesthetically appealing to the customers.

There are several conventional techniques used for concealing the fasteners. One conventional technique uses labels on front window to conceal screw heads. Another conventional technique uses a rubber or plastic on edge of the screw for concealing. Yet another conventional technique uses rubber cap to conceal screw at the bottom. However, the rubber cap is above the surface of the detector and drops off from the detector in many instances.

It would be desirable to have an improved technique for fastening the parts of a digital X-ray detector.

BRIEF DESCRIPTION OF DRAWINGS

Figure 1 depicts a concealed fastening structure for digital X-ray detector comprising a slot on a back cover of the detector, several clamping parts fixed in the slot, an adhesion frame is attached a front window of the detector, and a rivet held inside the holes in the adhesion frame.

Figure 2 depicts magnet required to drag the sleeve with the steel ball downward to release the rivet pins for disassembling the proposed fastening structure.
