Abstract
The utility model relates to a transmission mechanism used for an electric-controlled acesodyne filling pump, including a helical gear and a cam, one end of which is fixed on a big bracket separately, the big bracket is provided with two inverse Omega-port, the ends of the helical gear and the cam are embedded on the inverse Omega-port separately. the utility model resolves a problem of a great cumulative error generated by installing the cam, the helical gear and a shaft sleeve of the transmission mechanism of the existing electric-controlled acesodyne filling pump, such that usage safety and reliability are not stable.
Description
Technical field
This utility model relates to a kind of drive mechanism that is used for electric-controlled type pain relieving topping-up pump.
Background technology
At present, electric-controlled type pain relieving topping-up pump is divided into automatically controlled part and liquid storage part.Drive mechanism in automatically controlled part adopts elder generation that axle sleeve is fixed on the large and small support, again cam and helical gear are passed axle sleeve, make it unsettled in the centre bore of axle sleeve, by glue axle sleeve and big support, helical gear support and Cam rest are bondd again, as shown in Figure 1.Owing to big valve and the motion of minor valve of control flow is by cam and helical gearly cooperates rotation to produce, therefore more in the cumulative error of the installation process generation of cam and helical gear and axle sleeve, if one of them part is not in place, or it is incorrect, the risk that the later stage that produces uses will be difficult to estimate, not be very stable on security reliability.
The utility model content
Technical problem to be solved in the utility model is: at the defective that exists in the above-mentioned prior art, provide a kind of drive mechanism that is used for electric-controlled type pain relieving topping-up pump simple in structure, easy for installation.
This utility model is achieved in that
A kind of drive mechanism that is used for electric-controlled type pain relieving topping-up pump comprises that an end is fixed on helical gear and the cam on the big support, and described big support is provided with two mouths of falling Ω, and an end of described helical gear and cam embeds respectively in the described mouth of falling Ω.
The other end of described helical gear and cam lays respectively in the fixing hole of two small racks.
The beneficial effects of the utility model:
Adopt drive mechanism of the present utility model, cam and helical gear directly embedded in the mouth of falling Ω on the big support, removed this part of axle sleeve, reduced cumulative error, need not use 502 glue, to after use and reduced risk.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Description of drawings
Fig. 1 is the drive mechanism structural representation of existing electric-controlled type pain relieving topping-up pump.
Fig. 2 is a drive mechanism structural representation of the present utility model.
Wherein: 1, helical gear support 2, axle sleeve 3, helical gear 4, big support 5, axle sleeve 6, axle sleeve 7, cam 8, axle sleeve 9, Cam rest 10, the mouth of falling Ω 11, the mouth of falling Ω.
The specific embodiment
With reference to the accompanying drawings 2, the drive mechanism of electric-controlled type pain relieving topping-up pump comprises helical gear 3, the cam 7 that is fixed on the big support 4, one end of helical gear 3, cam 7 is embedded in the mouth of falling Ω 10,11 on the big support 4, the other end of helical gear 3 is arranged in the fixing hole on the helical gear support 1, and the other end of cam 7 is arranged in the fixing hole on the Cam rest 9.
Top embodiment only is used to this utility model is described and is not used in restriction scope of the present utility model that protection domain of the present utility model is described with claims of the present utility model and is as the criterion.Should be understood that in addition change or the modification of replacing various of equal value that those skilled in the art do this utility model falls within this utility model claims institute restricted portion equally after having read the content that this utility model tells about.
Claims (2)
1. drive mechanism that is used for electric-controlled type pain relieving topping-up pump, comprise that an end is fixed on helical gear and the cam on the big support, is characterized in that: described big support is provided with two mouths of falling Ω, and an end of described helical gear and cam embeds respectively in the described mouth of falling Ω.
2. the drive mechanism that is used for electric-controlled type pain relieving topping-up pump according to claim 1 is characterized in that: the other end of described helical gear and cam lays respectively in the fixing hole of two small racks.
