Description
Technical field
The utility model is related to technical field of motors, more particularly, to a kind of motor case and end cap coupling structure.
Background technology
In the prior art, motor case is generally fixedly connected with end cap by screw, it is easy to disassembled by other people, survey and draw and
It plagiarizes, one be easy to cause motor damage if disassembling, and greatly increases the after-sales maintenance service cost of enterprise, two carry out the new of enterprise
Technology and innovation are easily usurped by plagiarism, are brought serious loss to enterprise, are needed to improve.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of motor case and couple with end cap
Structure, it is simple and reasonable, effectively prevent other people from disassembling and surveying and drawing privately plagiarism.
In order to achieve the above objectives, the technical solution of the utility model is：A kind of motor case and end cap coupling structure, including
Columnar motor case, electric motor end cap, the motor case outer wall circumference uniform distribution several from end face toward centre extension it is recessed
Slot, the groove floor center are equipped with the first blind round hole, the electric motor end cap inner face outer marginal circumference it is uniformly distributed several with it is recessed
The convex block that slot fastens, the convex block bottom surface correspond to the first blind round hole position and are equipped with the second blind round hole, and described second is circular blind
It is fitted with compression spring and straight pin in hole successively from top to bottom, the electric motor end cap inner face, which is located on the inside of convex block, is equipped with ring
Sealing ring is equipped in connected in star and annular groove.
It is clearance fit between the straight pin and the second blind round hole.
It is clearance fit between the straight pin and the first blind round hole.
The straight pin height is more than the depth of the first blind round hole.
The beneficial effects of the utility model are：The utility model is simple and reasonable, and electric motor end cap is assembled with motor case
After finishing, it can only carry out destructiveness to disassembling and disassemble, greatly reduce the possibility that other people disassemble privately, and once tear open privately
Solution will cause motor damage, and such damage effectively reduces enterprise's after-sales service cost and prevent not in the range of after-sales service
Only other people disassemble and survey and draw privately plagiarism, highly practical.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the enlarged diagram at A in Fig. 1；
Fig. 3 is the stereogram of the motor case of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Fig. 1~Fig. 2, a kind of motor case and end cap coupling structure, including columnar motor case 1, motor
End cap 2, the 1 outer wall circumference uniform distribution of motor case several from end face toward centre extension groove 11,11 bottom surface of groove
Center is equipped with the first blind round hole 12, and the first blind round hole 12 must not run through 1 inner wall of motor case, 2 inner end of electric motor end cap
The uniformly distributed convex block 21 that several are fastened with groove 11 of face outer marginal circumference, 21 bottom surface of convex block corresponds to 12 position of the first blind round hole
Equipped with the second blind round hole 22, the first blind round hole 12, the diameter of the second blind round hole 22 are equal, second blind round hole 22
It is inside fitted with compression spring 3 and straight pin 4 successively from top to bottom, matches somebody with somebody between 4 and second blind round hole 22 of straight pin for gap
It closes, is clearance fit between 4 and first blind round hole 12 of straight pin, and 4 height of straight pin is more than the first blind round hole 12
Depth, when electric motor end cap 2 and the assembling of motor case 1, while convex block 21 is fastened with groove 11, straight pin 4 is in compression spring 3
It is sprung under effect in the first blind round hole 12, it is ensured that while electric motor end cap 2 and motor case 1 are blocked, 2 inner end of electric motor end cap
Face is located at 21 inside of convex block and is equipped in annular groove 23 and annular groove 23 equipped with sealing ring 5, improves electric motor end cap 2 and motor machine
Leakproofness between shell 1.
The foregoing is merely the preferable specific embodiment of the utility model, but the scope of protection of the utility model not office
It is limited to this, in the technical scope that any one skilled in the art discloses in the utility model, can readily occurs in
Change or replacement should be covered within the scope of the utility model.
