Description
Technical Field
The utility model relates to an oil buffering technical field, in particular to oil buffering adds buffer structure of dish reed combination.
Background
The spring over-center mechanism used by the quick grounding switch is provided with a buffer. The speed of opening and closing the switch of the spring over-middle mechanism mostly exceeds 1m/s, the spring over-middle mechanism has great kinetic energy, when the switch is closed, if the kinetic energy is not fully absorbed, the contact can rebound, the failure of the switch is caused, and the abrasion of the mechanism and the switch is accelerated by the overlarge impact force, and even the damage of the mechanism and the switch is caused. The buffer has the function of absorbing the redundant kinetic energy of the opening and closing when the opening and closing are nearly finished, preventing the contact from rebounding and simultaneously enabling the curve process of the opening and closing to be smooth.
Commonly used buffers are: (1) the oil buffer converts kinetic energy into heat energy to absorb the heat energy. (2) The spring buffer converts kinetic energy into potential energy, stores the potential energy and releases the potential energy when necessary. (3) The rubber cushion buffer converts kinetic energy into heat energy to be absorbed, and the structure is simplest.
The various buffers each have their own advantages and disadvantages. The oil buffer has the advantages that: the oil buffer has stable operation performance, can effectively ensure the buffering effect, and is suitable for the mechanism buffering with the opening and closing speed higher than 1 m/s; the disadvantages are that: when the final contact position is determined, the piston rod has strong impact, the contact rebounds, and the opening and closing speed curve has large fluctuation. The spring buffer has the advantages that: the structure is simple, the reserved compression amount is provided, and the buffer device is suitable for buffering the opening and closing speed of less than 1 m/s; the disadvantages are that: there is a periodic oscillation. The rubber pad buffer has the advantages that: the structure is simplest and the cost is low; the disadvantages are that: the buffer performance has temperature sensitivity and short service life.
Therefore, it is necessary to develop a buffer structure of oil buffer and disc spring combination to solve the above problems.
