Description
Technical field
The utility model relates to the technical field of damping device, especially a kind of air pressure pump damping device.
Background technique
Air pressure pump is the device that the mechanical energy of prime mover is converted to gas pressure energy, is compressed-air actuated pressure generator.The speedup that the market scale of the air pressure pump industry of China is more than 8% increases, and 2010-2011 annual growth has even exceeded 28%, and market scale expansion rapidly.
The part but existing air pressure pump structurally still comes with some shortcomings, existing most of air pressure pump, in work, can produce the violent sound and shake, and shock-proof effect is poor, motor is produced to very large damage, finally cause the working life of motor lower.
Summary of the invention
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology; the utility model provides a kind of air pressure pump damping device; can carry out good shock-absorbing to air pressure pump, protect motor, extend the working life of air pressure pump.
The utility model solves the technological scheme that its technical problem adopts: a kind of air pressure pump damping device, comprise the packing ring being arranged on air pressure pump supporting foot, on the inwall of packing ring, there is the stepped annular groove being formed by Vehicle Processing, the diameter dimension of annular groove increases progressively from top to bottom successively, the upper and lower end face of packing ring is respectively arranged with Upper gasket and lower levelling plate, on Upper gasket, offer mounting hole, on lower levelling plate, offer shock relieve vent.
Further limit: the diameter dimension that is opened in the diameter dimension of the mounting hole on Upper gasket and the Article 1 annular groove of packing ring upper inside wall is consistent.
Further limit: the diameter dimension that is opened in the shock relieve vent on lower levelling plate is less than the diameter dimension that is opened in the mounting hole on Upper gasket.
Further limit: packing ring is fixed on air pressure pump supporting foot by jump ring.
The beneficial effects of the utility model: this air pressure pump damping device, can carry out good shock-absorbing to air pressure pump, make air pressure pump in the time of work, can not produce the violent sound and shake, protect motor, extend the working life of air pressure pump.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is STRUCTURE DECOMPOSITION schematic diagram of the present utility model;
Fig. 2 is structural representation of the present utility model.
In figure: 1, packing ring, 2, annular groove, 3, Upper gasket, 4, lower levelling plate, 5, mounting hole, 6, shock relieve vent, 7, jump ring.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Air pressure pump damping device as depicted in figs. 1 and 2, comprise the packing ring 1 being arranged on air pressure pump supporting foot, on the inwall of packing ring 1, there is the stepped annular groove 2 being formed by Vehicle Processing, the diameter dimension of annular groove 2 increases progressively from top to bottom successively, the upper and lower end face of packing ring 1 is respectively arranged with Upper gasket 3 and lower levelling plate 4, on Upper gasket 3, offer mounting hole 5, on lower levelling plate 4, offer shock relieve vent 6.
Because the diameter dimension of annular groove 2 increases progressively from top to bottom successively, therefore the sound being produced by air pressure pump and shake transfer to along its supporting foot, packing ring 1 is interior to be weakened gradually afterwards, and then has played the effect of shock-absorbing.
The diameter dimension that is wherein opened in the mounting hole 5 on Upper gasket 3 is consistent with the diameter dimension of the Article 1 annular groove 2 of packing ring 1 upper inside wall.The diameter dimension that is opened in the shock relieve vent 6 on lower levelling plate 4 is less than the diameter dimension of the mounting hole 5 being opened on Upper gasket 3.Packing ring 1 is fixed on air pressure pump supporting foot by jump ring 7, make between air pressure pump supporting foot and packing ring 1 be connected more firm.
This air pressure pump damping device, can carry out good shock-absorbing to air pressure pump, makes air pressure pump in the time of work, can not produce the violent sound and shake, has protected motor, has extended the working life of air pressure pump.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this model utility technological thought, carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to claim scope.
