The utility model discloses an elevator car convenient to maintain, which belongs to the technical field of elevator car maintenance, and is characterized in that the elevator car comprises an elevator car body and a plurality of keys, the right side of the inner wall of the elevator car body is fixedly connected with a sliding rail, and the front sides of the keys are provided with a sliding wiping mechanism; a spraying mechanism is arranged at the bottom of the wiping mechanism; the elevator car key solves the problems that part of existing elevator car keys are mostly designed in a protruding mode, particularly in crowded places such as hospitals, schools and markets, the surfaces of the keys become potential media for cross propagation of bacteria and viruses, and when workers clean elevator car keys in different areas of public places on a large scale, the keys cannot be damaged. The problems that a worker needs to hold disinfectant and cleaning cloth by hand to spray the disinfectant and then wipe the cleaning cloth, cross-regional pollution is possibly caused if the cleaning cloth or a disinfection tool is not replaced in time, the worker is prone to making contact with more bacteria, and the body health of the worker is threatened to a certain degree are solved.

This utility model relates to the field of printing device technology, and in particular to a portable, trouble-resistant label printer. A portable, trouble-resistant label printer includes a printer body with an inner cavity, within which a paper jamming assembly and a guide groove are disposed. The paper jamming assembly includes: a connecting seat located on one side of the guide groove; a first paper jammer hinged to the connecting seat at a certain angle; a torsion spring, used to generate a restoring force applied to the first paper jammer when the angle between the first paper jammer and the connecting seat changes; and a second paper jammer movably mounted in the guide groove. This solution effectively solves problems such as difficult paper loading, high paper jam rate, severe printing misalignment, and difficulty in cleaning sensors in the prior art, significantly improving the user experience and reliability of label printers.
