Abstract

The invention discloses a full-automatic steady flip device capable of damping gear movement. The same spindle is connected with a box body left damping movement structure and a box body right gear movement structure. After a motor starts, due to the transmission of every level of speed reduction gear and transition gear, limit swinging teeth are driven to rotate finally, and simultaneously the spindle rotates clockwise and anti-clockwise through a torsional spring. Therefore, the opening or descending of a flip can be realized. The spindle rotates to drive blades to rotate, and the damping action of the liquid makes the gear transmission steadier. A gap between each level of gear is regulated through each eccentric gear shaft to increase or reduce the friction between gears, so that the influence on the damping of the liquid viscosity change due to the temperature change is removed. A sleeve is arranged so as to effectively maintain the precision of mutual alignment of front and rear eccentric shafts.

Description

Automatic steady flip device

Technical field

The present invention is that a kind of flip structure of two kinds of different motion principles is linked by same motion main shaft realized the device of automatic steady flip.

Background technology

Along with the research and development of China's new product, kind grows with each passing day, and the motion structure of renovating of all styles of is given birth to therefrom.Usually there are two kinds in the market and renovate motion structure, but all have defective not fully up to expectations:

Renovating of damped motion principle, lid is fully by manually starting, could descend by automatic slowly after need turning back a special angle (lid is in the angle that can descend automatically under the action of gravity) to lid when resetting, the damped motion effective range only limits to lid a period of time when resetting, in case and temperature Change is when big, because the damping liquid viscosity-modifying, the deadweight drop point changes thereupon, the also corresponding change of decrease speed, thus the stability of product quality influenced.

Renovating of gear movement principle, be conduction and torsionspring through gears at different levels, make lid do to open or down maneuver by main shaft, though can realize full-automatic the unlatching and decline, but because the influence of motional inertia, gravity or other factors, lid is easy to generate vibration, and reseting performance is poor, can break down when serious, influence is normally used.

Summary of the invention

In order to overcome the defective of above two kinds of motion principles, invented a kind of motion structure that integrates the advantage of two kinds of motion principles, lid dig and reset to lid by the deadweight can descend angle the time, be to utilize the gear drive that has damping, when lid can fall to resetting under the self gravitation effect, the gear drive dump, utilizing has the motion of damping that the lid automatic steady is resetted, and this structure is an automatic steady flip device.

The present invention takes following technical scheme to realize:

By main shaft connect box left side damped motion structure and casing the right gear movement structure.Behind the electric motor starting,, finally drive spacing pendulum tooth and rotate, utilize torsionspring simultaneously, make main shaft do clockwise, be rotated counterclockwise, thereby realize the unlatching or the decline of lid through the conduction of decelerations at different levels and transition gear.Main shaft rotates and drives the scraping blade rotation, and the damping action of liquid makes gear drive more steady.Adjust gear clearances at different levels to increase or to reduce friction between gear by each eccentric shaft, be provided with sleeve pipe adjust with effective maintenance before and after the precision of each eccentric shaft mutual alignment.

Advantage of the present invention:

1) the damped motion structure division need not manually be finished: transmitted by the running of gear transmission structure by main shaft and realize;

2) vibration of elimination gear movement, reach the steady of motion: the damping action of damped motion structure makes gear drive more steady;

3) damping adjustable size: liquid viscosity has bigger variation with temperature, influences the effect of damped motion, adjusts gear clearances at different levels increasing or to reduce friction between gear by each eccentric shaft, thereby guarantees that effectively this installs required damping size.

The specific embodiment

Have demarcation strip C that integral body is divided into left and right sides two halves in the middle of the casing (23), upper left is the fluid damping chamber, and motor is installed in the lower-left, and right half part is installed the gear motion.Main shaft (1) penetrates upper right half chests body through upper left half chests body, carries out axial location by axle stifle (3) and right case lid (22); Main shaft (1) center has circular arc flat through hole E, is connected the realization transmission of power with the subsidiary roller pin of this device with flat axis hole on the lid that will stir.Main shaft (1) left end is provided with the two symmetrical groups locating hole, scraping blade (5) is combined the recessed gap delta in middle part, scraping blade (5) lower end respectively by scraping bobbin (6).Carry out sealing to prevent liquid leakage with axle stifle (3) and separator for container respectively with sealing ring (2) and sealing ring (7).Main shaft (1) right-hand member is equipped with spacing pendulum tooth (10), is cooperated fixing by key (9); Torsionspring (8) internal diameter encapsulation is on spacing pendulum tooth (10), and one end right angle head inserts the aperture F on the spacing pendulum tooth (10); Torsionspring (8) is tightened by pressure when renovating closure, renovates the moment of rising behind the motor start-up, the load the when rebound effect of spring alleviates the gear startup; Stud with crescent moon magnetic sheet (31) on the spacing pendulum tooth (10), carry out the folding degree that the signal transmission is renovated with control with the chip (30) that is fixed on the casing demarcation strip C.Each eccentric shaft (12) (16) (19) is fixing by sleeve pipe (14) (20) (28) and nut (26), packing ring (27), all can adjust eccentric shaft to obtain required motion gear clearance (adjusting the gear clearance device applies for a patent separately) according to the size of damping and the variation of temperature.

After motor (24) starts,, finally drive main shaft (1) and rotate through gear conduction at different levels, thus unlatching or decline that realization is renovated.Main shaft (1) is when clockwise rotating, scraping blade (5) is opened with the flow direction of damping liquid, fluid flow is bigger, damping action is little, renovate unlatching, when the crescent moon magnetic sheet (31) on the spacing pendulum tooth (10) be fixed on chip (30) position on the casing demarcation strip C and stagger that motor (24) shuts down when making signal interruption, lid reaches maximum opening angle; Main shaft (1) is when rotating counterclockwise, cap closure, to lid by the deadweight can descend angle the time motor (24) shut down, because scraping blade (5) is stopped by the step D on the main shaft (1), damping liquid can only slowly enter the other end by its middle part, lower end gap delta, flow is little, and damping torque increases, and lid steadily resets under action of gravity.
