Description

Display screen fixing device Technical Field The utility model relates to the technical field of display screen fixing, in particular to a display screen fixing device. Background Currently, with the continuous development and application of medical instruments, more and more devices are beginning to be equipped with a display screen as an operation medium. These displays serve as the core control interface for the device, typically for displaying information, operating settings, and feedback user instructions. Therefore, the stability and protection of the display screen is critical to the proper use of the medical device. During use of the device, the operator is often required to periodically maintain and clean the device, where liquid cleaners and the like may come into contact with the display screen and surrounding structures. Without effective protection, liquid may penetrate into the interior of the device through the gap between the display screen and the fixed frame, thereby affecting the performance of the device and even causing malfunction of the device. For this reason, two main fixing means are generally used in the prior art to prevent liquid penetration. The prior art is to use a rigid press-fit, i.e. to firmly fix the display screen in the frame by mechanical forces. This method generally ensures stability of fixation, but has a disadvantage in that if the force is applied too much or unevenly during the assembly, breakage of the display screen is easily caused, and particularly, in mass production and assembly, the breakage rate is high, thereby increasing the cost of production and maintenance.
