Abstract
The utility model discloses an automatic pressure discharge mechanism for a motor. A vent hole is arranged in a casing of the motor; a threaded hole is arranged on the lateral side of the vent hole; a screw is in threaded connection with the inside of the threaded hole; the screw is sleeved and connected with a plastic gasket and a spring; the outer ring of the plastic gasket can cover the vent hole; and the upper end of the spring can be jacked by the screw head of the screw, so that the lower end of the spring can be used for elastically jacking the plastic gasket on the vent hole. In the automatic pressure discharge mechanism, the plastic gasket is elastically jacked on the vent hole through the spring, so that air subjected to thermal expansion in the casing of the motor can be used for jacking and opening the vent hole and is discharged from the vent hole; and the vent hole is shielded by the plastic gasket in normal times, so that sundries and dust can be prevented from falling in the casing of the motor.
Description
Technical field
The utility model relates to the row pressure structure of motor.
Background technique
After the motor long-term operation, can produce great amount of heat and make air expanded by heating in the electric machine casing, if untimely discharge can influence the normal operation of motor.Usually on housing, set up exhaust port in the existing technology, though exhaust port has been discharged heat, but foreign material or dust also can get in the electric machine casing, and operation impacts to motor.
The model utility content
The utility model technical problem to be solved just provides a kind of motor automatic discharging pressure mechanism, and the heat of in time discharging in the electric machine casing can not make the dust foreign material get in the electric machine casing simultaneously.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: motor automatic discharging pressure mechanism is characterized in that: electric machine casing is provided with an exhaust port, and said exhaust port side is provided with a tapped hole; The tapped hole internal thread connects a screw; Socket one a plastic cement pad and a spring on the screw, wherein plastic cement pad outer ring can cover exhaust port, and the spring upper end makes the spring lower end that plastic cement pad elastic top is pressed on the exhaust port by the screw head roof pressure of screw.
As preferably, said exhaust port diameter is less than the tapped hole diameter.
As preferably, said spring is a volute spring, and volute spring bigger diameter end roof pressure plastic cement pad.
As preferably, said exhaust port is that cone shape hole and bigger diameter end are located at hull outside.
In the utility model the plastic cement pad by the spring roof pressure on exhaust port; Like this; Can roof pressure behind air expanded by heating in the electric machine casing begin to rehearse pore and discharge from exhaust port, and at ordinary times because the blocking of plastic cement pad, foreign material and dust can not fall in the electric machine casing yet.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is a housing upper groove schematic representation;
Fig. 2 is screw, spring and plastic cement pad linkage structure schematic representation.
Embodiment
As depicted in figs. 1 and 2; Be the embodiment of the utility model motor automatic discharging pressure mechanism, electric machine casing 1 is provided with an exhaust port 5, and said exhaust port side is provided with a tapped hole 4; The tapped hole internal thread connects a screw 6; Socket one a plastic cement pad 8 and a spring 7 on the screw, wherein plastic cement pad outer ring can cover exhaust port, and the spring upper end makes the spring lower end that plastic cement pad elastic top is pressed on the exhaust port by the screw head roof pressure of screw.Said spring is a volute spring, and volute spring bigger diameter end roof pressure plastic cement pad.
Improve as the foregoing description, said tapped hole and exhaust port all are located in the circular groove 3 that annular protrusion 2 surrounds on the housing, and its further groove internal diameter equals plastic cement pad diameter.Said exhaust port diameter is less than the tapped hole diameter.Said exhaust port is that cone shape hole and bigger diameter end are located at hull outside.
