The invention relates to a hidden turnover ladder. The hidden turnover ladder is characterized by comprising an upper ladder assembly and a lower ladder assembly, wherein the upper ladder assembly comprises a baseplate, and a pair of mounting vertical plates symmetrically arranged on the baseplate; multiple stages of upper antiskid pedals are arranged between the mounting vertical plate; first pin shaft holes are formed in the lower front parts of the mounting vertical plates; the lower ladder assembly comprises a pair of step type mounting side plates; connecting lug plates are arranged at the upper ends of the mounting side plates, and are rotationally connected with the first pin shaft holes through first pin shafts; and multiple stages of lower antiskid pedals are arranged between the mounting side plates. The hidden turnover ladder has the beneficial effects of less occupied space, convenience for use and folding capacity in no use. The invention further discloses oil field operation equipment adopting the turnover ladder; and the oil field operation equipment has the following beneficial effects: second pin shafts are arranged for connecting a car body with the hidden turnover ladder, so that the turnover ladder can be accommodated in a turnover ladder accommodating cavity after two times of overturning, and the effect of convenience for use and transportation is achieved.

A display structure of a slip-cover-hinge electronic device, which includes a housing, a display module, two track modules and a flexible-printed-circuit module, is disclosed. The housing has an accommodated cavity formed with a bottom wall, two parallel slots formed respectively at two opposite ends of the bottom wall, and a passageway formed between the two slots and on the bottom wall. The display module is connected within the cavity. Each track module has a track disposed on the opposite ends of the bottom wall and a skid slidably arranged onto the corresponding tracks for gliding in corresponding slots. The flexible-printed-circuit module has at least a flexible-printed-circuit member, which includes an electrical connection portion and a resilient portion flexibly extending from the electrical connection portion. The resilient portion extends out of the passageway of the housing, and the resilient portion is partially self-overlapped to be capable of stretching outwardly.

The invention provides a method and a device for clearing memory of a mobile terminal and the mobile terminal. The method for clearing the memory of the mobile terminal includes steps: obtaining the memory size of the mobile terminal, and obtaining corresponding clearing threshold value according to the memory size of the mobile terminal; obtaining memory information occupied by application programs which survive backstage, judging whether the application programs which survive backstage reach the clearing threshold value according to the memory information, and if yes, confirming the application programs to be cleared, and killing processes corresponding to the application programs to be cleared so as to release memory space occupied by the application programs to be cleared. The method and the device for clearing the memory of the mobile terminal and the mobile terminal automatically release the memory space occupied by the application programs to be cleared, avoid operation complexity generated when a user manually clears the memory, can timely reduce the size of the memory of the mobile terminal, occupied by the application programs which survive backstage, and improves running efficiency and performance of the mobile terminal.
