Abstract
The utility model relates to a low noise inflator pump, which comprises an air cylinder, a piston, a bracket, a motor and an eccentric cam. The utility model is characterized in that the lateral side of the bracket is fixedly connected with a cover body, consequently a space for containing and installing the eccentric cam and a piston connecting bar is formed. Compared with the prior art, the utility model effectively reduces the work noise of the inflator pump by arranging the cover body outside the eccentric cam.
Description
Technical field
The utility model relates to gas-filled pump, specifically refers to a kind of long service life, the low noise gas-filled pump that noise is low.
Background technique
Along with the development of industrial technology and the raising of people's living standard, various vehicle tyres and inflatable product are more and more, also arise at the historic moment therefore for the various gas-filled pumps of these product inflations.Existing gas-filled pump generally includes support, rack-mount motor, eccentric cam and cylinder; Described motor is connected one with support, and described motor is by gear train transmission eccentric cam; Directly connect by coupling shaft between described eccentric cam and the gear train; Described eccentric cam is positioned at the outside of support; The connecting rod of cylinder connects the eccentric shaft of cam, and the eccentric rotary of cam is converted to the to-and-fro motion of connecting rod, thereby drives the to-and-fro motion of cylinder cap, produces gas, discharges from the pore of housing to charge in the tire wait inflatable object.
In the existing gas-filled pump, because motor and support link into an integrated entity, motor and gear train all are positioned at the installing space of support, and consider that the flexibility of rotation has been arranged on eccentric cam in the outside of support.Generally, eccentric cam and motor are arranged on the bottom of support, and cylinder then is arranged on the top of support, with switching that makes things convenient for moving direction and the compact structure that makes gas-filled pump.Gas-filled pump of the prior art, the component of each motion class are all exposed outside, and during work, motor, eccentric cam all can high speed rotating, produce bigger noise; The connecting rod of cylinder and the motion of cylinder cap simultaneously also can produce noise, and surrounding environment is caused noise pollution.
Summary of the invention
Technical problem to be solved in the utility model is that the present situation at prior art provides a kind of low noise gas-filled pump.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: this low noise gas-filled pump, comprise cylinder, piston, support, motor, eccentric cam, it is characterized in that: the side of described support is fixed with cover body, thereby forms the space of ccontaining setting-up eccentricity cam and piston brace rod.
Have the first ring limit of evagination and sealing on the end face of described cover body, the end face of this first ring limit and described cover body constitutes groove, and the bottom surface of this groove is provided with air hole, and flexible ventilative piece is embedded in this groove; Described first ring is provided with outside the limit the capping of this groove button cover in it.
Also be provided with the second ring limit of sealing on the end face of described cover body in the periphery on the described first ring limit, the periphery wall on this second ring limit is provided with screw thread; Described capping is cylindric, also is provided with screw thread on the inner circle wall of capping; Described closure threads connects the described second ring limit, and the end face of described capping is provided with pore.
The ventilative piece of described flexibility is a sponge block.
Compared with prior art, the utility model by in the eccentric cam arranged outside with its cover cap at interior cover body, effectively reduce the operating noise of gas-filled pump; Especially the setting of capping and flexible ventilative piece, under the prerequisite of cover body blocking noise, the noise that has further blocked and sent during soft gas-filled pump work, noise reduction further improves.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, this low noise gas-filled pump comprises:
Motor 8 is arranged in the support 1, links into an integrated entity with support 1;
Cylinder 3 is arranged on the top of support 1, and is positioned at the top of eccentric cam 2; The eccentric shaft of eccentric cam 2 connects the connecting rod of cylinder 3, and this connecting rod is converted to the to-and-fro motion of connecting rod with the rotation of eccentric cam, thereby reaches the purpose of inflation.
Sponge block 6 is embedded in groove 52.
During use, because stopping of cover body 5, sponge block 6 and capping 7 effectively reduces noise.
