Background

Postpone along with the time, the door body of many occasions need keep different opening angles, for example the rest position of bedroom, and the beginning needs to close the door and keeps quiet environment, and when the night is dark, need open the door in order to supply oxygen, if manual operation, it is comparatively loaded down with trivial details, influences the sleep quality. Particularly, in the rest place of infants, in order to ensure the quiet rest environment, the door needs to be hidden to form a good quiet space, and the door can be gradually opened to keep the oxygen supply effect when people are quiet at night. The electric delay propelling tool is suitable for external use spaces such as a residential area, a large yard door and the like, a large space is needed for circuit installation, and the electric delay propelling tool needs to be continuously powered and is not suitable for long-term use indoors; some hinged positioners are commonly used for large fireproof doors in office and teaching markets and the like, repeated and tedious adjustment is not needed after the opening degree is adjusted, the closing effect is good, but manual operation is needed, and the angle flexibility is low; in addition, the magnetic door fixer and the pedal door fixer can fix the door body, only play a role in absorbing the terminal and cannot adjust the opening degree, and similarly, the magnetic door fixer and the pedal door fixer also have a positioner for preventing the door body from being tightly closed and opened, the three parts all emphasize the fixing effect and do not have the whole slow release process, so that the function of facilitating angle adjustment is not provided. Therefore, it is necessary to design a new technical solution to comprehensively solve the problems in the prior art.

The invention mainly compresses the spring through the elastic energy storage mode of the piston spring and the external force action, so that the spring sucks gas to form conversion from elastic potential energy to pressure energy while compressing under the action of the piston spring, the damping hole delays the release speed in the process of slowly releasing gas to achieve the purpose of slowly releasing for a long time, and meanwhile, as the two ends of the damping hole can form effective communication and is similar to the effect of a communicating vessel, the pressure and the pressure at the communicated part of the two ends are the same, thereby converting the elastic potential energy into the pressure of the gas pump body, and further being capable of releasing the pressure through the damping hole to push the change of the outline dimension of the corrugated pipe; the change range of the external dimension of the corrugated pipe mainly depends on the energy storage energy sum formed by the energy storage component, for the stroke change of the energy storage component, the suction air pressure is realized mainly through the change of the pull-out axial distance of the piston rod, and the change of the energy storage energy is determined by the change of the volume. When the energy storage component is operated, the energy storage process of the energy storage component is firstly completed, then the deformation corrugated pipe is connected, the energy storage component is slowly released, the deformation corrugated pipe is slowly stretched, namely the pulling-out displacement of the energy storage component in the initial state determines the extension length of the deformation corrugated pipe.
