The invention, based on an existing cooking device, is improved, and provides a detonation accumulation mechanism and a cooking device adopting the same. The detonation accumulation mechanism comprises a motor, a first magnetic connecting plate, a magnetic conductive metal plate, a detonation accumulation spring, a detonation accumulation limiting device and an output connecting piece, wherein a thread output shaft is arranged on the motor, the first magnetic connecting plate is arranged on the thread output shaft, and the magnetic conductive metal plate penetrates through the thread output shaft. By removal of a redundant structure and continuous improvement and optimization, the detonation accumulation mechanism can realize more cooking functions, and achieve a better cooking effect, thereby improving the automation degree of cooking. By virtue of a working mode of accumulating and then releasing mechanical energy, the detonation accumulation mechanism provided by the invention can provide energy output by using a power source with higher power, smaller volume and smaller mass, strengthen the action effect greatly by virtue of this power source, achieve an effect of outputting a same equivalent weight with higher power source energy, and replace an execute component (such as an electromagnet) acting directly in the prior art.

The invention discloses a sealing structure of a cylindrical roller. The sealing structure comprises an outer ring, an inner ring and double rows of rollers, the double rows of rollers are arranged between the outer ring and the inner ring in a rolling mode, the two ends of the outer circumferential wall of the inner ring protrude towards the inner circumferential wall of the outer ring to form baffle rings, the end surfaces of the baffle rings are in clearance fit with the inner circumferential wall of the outer ring, annular grooves are formed in the end surfaces of the baffle rings in a sunken mode, isolation rings are arranged in the two annular grooves and made of elastic materials, one part of the outer circumferential wall of each isolation rings is connected with the inner circumferential wall of the outer ring, the other parts of the outer circumferential walls of the isolation rings abut against the inner walls of the annular grooves, openings are formed in the isolation rings, and the isolation rings are in arc ring shapes. The problem that a bearing is damaged due to the fact that external impurities enter the bearing easily in the prior art is solved.

The invention discloses a hydraulic cylinder control valve without unloading impact resonance, which overcomes the problem that impact resonance is generated by the unloading of a hydraulic control one-way valve of a conventional hydraulic cylinder. The hydraulic cylinder control valve without unloading impact resonance is characterized in that: a sealing diameter of a valve opening of a first valve core inside a valve body is same as a diameter of a sealing section and a diameter of a liquid return section; and the diameter of a control section is smaller than the diameter of a liquid return section. The beneficial effects are that: as the sealing diameter of the valve opening of a first valve core is same as the diameter of the sealing section and the diameter of the liquid return section, the unloading impact resonance problem of the control valve of the hydraulic cylinder is solved; as the sealing diameter of the valve opening, the diameter of the sealing section and the diameter of the liquid return section can be increased equivalently, and the diameter of the control section can be reduced at will based on a need, the control pressure is unlikely too low, and no false operation is generated; and a secondary-hole one-way valve arranged in a secondary hole inside the valve body or a plate-shaped connecting one-way valve or a tubular one-way valve outside the valve body are used for raising a column, so that needs of big channel for dropping the column, a small channel for raising the column, and joint control of a balancing jack and a lifting jack while the column is raised are satisfied.

The invention discloses an avionics cabin equipped with an LRM, which includes a cabin body, a vertically fixed avionics equipment fixing plate is arranged in the cabin body, and several top fixing legs are fixed above the cabin body. The top fixing feet are used for: fixedly connecting the cabin body with the aircraft body, and buffering the cabin body from the vibration of the aircraft body; below the cabin body, a vibration-reducing and heat-dissipating air cushion is fixed, and the vibration-damping and heat-dissipating air cushion Several exhaust ports are opened on the upper surface, and pressure relief valves are arranged in the exhaust ports, and an air injection pipe is fixed below the vibration-reducing and heat-dissipating air cushion. The invention realizes the functions of fixing, shock absorption and enhancing heat dissipation at the same time by using the same placement compartment, so that the space in the aircraft is saved, and at the same time, the damage to the avionics equipment caused by vibration and temperature changes can be avoided.

The present invention provides a lockup pressure control method of a lockup clutch in a hydraulic torque converter. In the third stage, the lockup clutch duty ratio is set to The ratio increases numerically according to the first slope; and it is judged whether the slipping speed of the lock-up clutch is less than a predetermined threshold, and if it is less, then delay the predetermined time to enter the fourth stage; otherwise, directly enter the fourth stage. In the third stage, the first slope adapts to the sliding speed of the lock-up clutch and the input torque of the engine, so that the lock-up clutch can be smoothly transitioned before being pressed, reaching a stable state, which reduces the impact caused by the fixed-slope pressing; in addition, with the second The torque transmission point just in the stage is based on the duty cycle value of the lock-up clutch to sweep the point to realize the locking control, which does not rely on the self-learning of the torque transmission point and has high robustness.
