In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of quick and convenient disassembly knot of electric motor end cap
Structure, the motor include end cap and base, and the end cap is assembled together with base by end cap mating surface and base mating surface；
On the end cap, at least two are offered positioned at the lateral area of end cap mating surface and runs through end cap tow sides
Tapped through hole, at least two tapped through hole are arranged along end cap circumferential direction uniform intervals；On the base, positioned at base mating surface
The position that lateral area corresponds to tapped through hole is equipped at least two boss, which is equipped with an ejection face；It further include opening knot
Structure, the structure that opens includes mandril, which is equipped with external screw thread, the tapped through hole phase equipped with externally threaded mandril with end cap
Matching, and the ejection end of mandril is towards the ejection face of boss.
Related content in above-mentioned technical proposal is explained as follows：
1, in above scheme, the ejection face of the boss is lower than base mating surface.
2, in above scheme, two tapped through holes are arranged in the end cap, and two boss are arranged on corresponding base.
3, in above scheme, the line of described two tapped through holes passes through the center of circle of end cap.
4, in above scheme, the structure that opens is bolt.
Working principle：Two tapped through holes are arranged in the utility model at the non-mating surface of end cap mating surface lateral area,
Setting boss at the position of tapped through hole is corresponded on base, it further includes ejecting structure that boss, which is equipped with ejection face, the ejection knot
Structure includes mandril, and mandril is equipped with external screw thread, and the ejection end of mandril is towards the ejection face of boss.When disassembly, first back-out end cap with
The connection bolt of base, then open structure with two while being screwed into both sides and set in internal thread tapped through hole, mandril bottom top
On the ejection face of boss, so that end cap be jacked up.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：
The utility model structure is simple, is skillfully constructed, good reliability, can quickly and easily tear end cap from base open
The mating surface that end cap and base can be effectively avoided damage to when unloading, and dismantling, has ensured the leakproofness of motor.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments：
Embodiment：A kind of quick and convenient detaching structure of electric motor end cap
Referring to attached drawing 1-4, the motor includes end cap 1 and base 2, and the end cap 1 passes through end cap mating surface 10 with base 2
It is assembled together with base mating surface 20.
On the end cap 1, open up positioned at the lateral area of end cap mating surface 10 there are two running through 1 tow sides of end cap
Tapped through hole 101, two tapped through holes 101 are along the circumferential uniform intervals arrangement of end cap 1, i.e., the line of two tapped through holes 101
By the center of circle of end cap 1.
On the base 2, set positioned at the position that the lateral area of base mating surface 20 corresponds to tapped through hole 101 there are two convex
Platform 201, the boss 201 are equipped with an ejection face.
It further include opening structure 3, the structure 3 that opens includes mandril, wherein the corresponding configuration one of each tapped through hole 101
Mandril, mandril are equipped with external screw thread, and the tapped through hole 101 equipped with externally threaded mandril and end cap 1 matches, i.e., the two shape,
Size and position match.The ejection end of mandril is towards the ejection face of boss 201.It is described to open structure 3 in the present embodiment
Using bolt.Ejection face on the boss 201 is lower than base mating surface 20.
In the disassembled condition, the mandril is screwed into the tapped through hole 101 by being threadedly engaged, and withstands on boss 201
Ejection face on, end cap 1 is jacked up with respect to base 2.
Two tapped through holes 101, two spiral shells are arranged in the present embodiment at the non-mating surface of 10 lateral area of end cap mating surface
Line through-hole 101 be separately positioned on 1 two sides of end cap and with 1 center of circle of end cap point-blank.Tapped through hole is corresponded on base 2
Boss 210 is set at 101 position.Boss 201 is equipped with ejection face, and when disassembly first back-outs the connection spiral shell of end cap 1 Yu base 2
Bolt, then the mandril for opening structure 3 with two simultaneously are screwed into the tapped through hole 101 on both sides respectively by being threadedly engaged relationship, are pushed up
The bottom of bar is withstood on the ejection face of boss 201, and end cap 1 is jacked up.At this time, it may be necessary to it is to be noted that：Both sides open structure 3 and need
It being screwed into simultaneously, preventing the inclination of end cap 1 damage seam allowance when because jacking up end cap 1.
In addition, in the present embodiment, connection bolt when can also assemble electric motor end cap 1 and base 2 is as opening structure
3, i.e., in disassembly, it can first back-out the connection bolt of end cap 1 Yu base 2, then bolt opening as the present embodiment will be connected
Structure 3, while be screwed into the tapped through hole 101 on both sides respectively with two connection bolts by being threadedly engaged relationship, connect bolt
Bottom withstand on the ejection face of boss 201, end cap 1 is jacked up.Certainly, externally threaded mandril is had using other, also can
It realizes, be not limited in limiting in the application opens structure.
