Specific embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein ad initio Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng The embodiment for examining Description of Drawings is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

The pumping 100 according to the utility model embodiment is described below with reference to Fig. 1-Fig. 5.

Pumping 100 according to the utility model embodiment, as shown in Figure 1-Figure 3, including：Motor 1 and for fixing pumping The base 2 of 100 piston (not shown).Motor 1 has shell 11 and motor shaft 12, and shell 11 is stretching out the end of motor shaft 12 Face 111 is provided with the first fastener 13.Base 2 has bottom wall 21 and perisporium 22, and the bottom wall 21 of base 2 is connected to the end of motor 1 On face 111, bottom wall 21 is provided with for the axis hole 211 through motor shaft 12, is additionally provided with bottom wall 21 and matched somebody with somebody with the first fastener 13 The second fastener 23 for closing.

Pumping 100 according to the utility model embodiment, to snap connection between base 2 and motor 1 in pumping 100, this Sample, dismounts between base 2 and motor 1 and connects very convenient, and decreases the threaded connection between base 2 and motor 1, from And reduce processing cost.

It is understood that the shell 11 of motor 1 is usually tubular, if the first fastener 13 is arranged on into motor periphery On wall, base 2 is accomplished by entangling motor 1 and then the second fastener 23 is set on the internal perisporium of base 2, and this results in pumping 100 Increase in the junction diameter, and the second inside fastener makes base 2 be not easy to the demoulding in processing.And it is new in this practicality In type embodiment, the first fastener 13 is arranged on the end face 111 of motor housing 11, then the second fastener 23 is arranged on bottom On the bottom wall 21 of seat 2, can effectively solve the above problems.

Specifically, as shown in Figures 2 and 3, the first fastener 13 is formed as hole clipping, and the second fastener 23 is formed as grab.

It is understood that the machining accuracy of motor 1 is often high compared with miscellaneous part, therefore first is set on motor 1 If to keep the required precision its processing also can be more difficult than miscellaneous part during fastener 13.Therefore the utility model embodiment In, hole clipping is set on the end face 111 of shell 11 of motor 1 to constitute the first fastener 13, grab is processed on base 2, can drop The difficulty of processing of low pumping 100.

Alternatively, as shown in Figures 2 and 3, hole clipping insertion shell 11 on the thickness direction of shell 11, the head of grab is stretched Enter in shell 11.Wherein, the head of grab is hooked on the inner face of shell 11, is so set, it is ensured that base 2 and motor 1 it Between connect reliability.

Advantageously, as shown in figure 3, the bottom wall 21 of base 2 is provided with through hole 212, grab adjacent through-holes 212 are set, through hole 212 setting forms grab when base 2 can be facilitated to mold.In addition, grab is when hole clipping is inserted, grab needs deformation, therefore adjacent Nearly grab sets through hole 212, also can Portable hook deform in stress.

Further, the first fastener 13 is multiple, and the wound motor axle 12 of multiple first fasteners 13 is spaced apart and sets.This Sample, can further improve the connection reliability between base 2 and motor 1.

In certain embodiments, as shown in Fig. 5 and Fig. 2, leg 24 is additionally provided with base 2, leg 24 is along the outer of bottom wall 21 Week is along extension and is enclosed within the periphery wall of motor 1 outward.That is socket can be also formed between base 2 and motor 1 to coordinate, this Sample, when being impacted, the first fastener 13 and the second fastener 23 are not easy to thread off.

In certain embodiments, as shown in Figure 4 and Figure 5, the perisporium 22 of base 2 is provided with holding firmware 25, and such base 2 can Other compositions snap connection cooperation with pumping 100.

Specifically, as shown in Figure 4 and Figure 5, the part perisporium 22 for being provided with holding firmware 25 of base 2 is inwardly concaved.So, pump Pu 100 is smaller and more attractive in appearance in profile in the junction diameter of holding firmware 25.

Specifically, holding firmware 25 is spaced apart setting for multiple and around axis hole 211, can so improve base 2 and other structures Part connection reliability.

In a specific embodiment of the present utility model, as Figure 1-Figure 5, motor 1 has shell 11 and motor shaft 12, motor shaft 12 is located in shell 11 and is stretched out from an end face 111 of shell 11, and the end face 111 of shell 11 is provided with and passes through Lead to the hole clipping of its thickness.Base 2 has bottom wall 21, perisporium 22 and leg 24, and perisporium 22 and leg 24 are respectively provided at bottom wall 21 Opposite sides, and perisporium 22 and leg 24 are respectively along the periphery of bottom wall 21 along extending vertically.The wherein periphery of leg 24 and motor 1 It is enclosed within the periphery of motor 1 outside adaptation, and leg 24, bottom wall 21 is connected with the above-mentioned end face 111 of motor housing 11.On bottom wall 21 It is additionally provided with the grab for inserting hole clipping.Grab, hole clipping are one-to-one multiple, and multiple hole clippings are spaced apart wound motor axle 12 Set, and grab is three in Fig. 4.

It is additionally provided with holding firmware 25 on the perisporium 22 of base 2, holding firmware 25 is formed as the shape of gib head, gib head is from base 2 Perisporium 22 stretches out, and one end away from the second fastener 23 of gib head is formed as tip.Gib head is three, and three gib heads surround Axis hole 211 is spaced apart and sets, and three the second fasteners 23 are staggered with three gib heads in the circumference of base 2.

Wherein, beyond the end face of perisporium 22 of base 2 in the axial direction of motor 1, each gib head is in the footpath of motor 1 for each gib head Upwards in the circle that the profile of perisporium 22 of base 2 is formed.Pumping 100 according to the utility model embodiment, is easily worked, and Cost is relatively low.
