Abstract
The utility model discloses a waterproof structure for a screw hole of a motor end cover. The waterproof structure comprises an end cover body (1). A bearing block (2) is downwards raised from the middle part of the bottom surface of the end cover body (1); a plurality of lug bosses (5) are arranged outside the top surface of the end cover body (1); and screw holes (4) are reserved in the lug bosses (5). The lug bosses are arranged on the top surface of the end cover, and are provided with the screw holes, so that the hidden danger that water enters the screw holes is effectively eliminated; and the waterproof structure is simple, and has a good waterproof effect.
Description
Technical field:
The utility model relates to a kind of waterproof construction of electric motor end cap screw hole.
Background technology:
Outdoor motor needs waterproof sealing property preferably, and to improve its reliability, the place that general outdoor motor gets into rainwater mainly is place, electric motor end cap mounting screw hole; As depicted in figs. 1 and 2, traditional end cap comprises end cap body 1, and some steps 3 are offered in the end face outside of end cap body 1; Step 3 bottom surfaces are provided with screw hole 4; There is defective in the structure of screw hole 4, because the screw hole place is the outermost place of the lowest part and the end cap of end cap, the rainwater on the end cap flows away from here; Because screw and the influence of screw hole composition surface roughness; Just there is fit clearance in the cooperation, will causes rainwater to flow into motor internal, make motor have potential safety hazard from screw and screw hole fit clearance.
Summary of the invention:
The purpose of the utility model is to the technological deficiency that exists in the prior art, a kind of waterproof construction of electric motor end cap screw hole is provided, through setting up boss at the end cap end face; Boss is offered screw hole; Effectively solve the hidden danger of screw hole water inlet, simple in structure, good water-proof effect.
The purpose of the utility model is to be achieved through following technical scheme.
A kind of waterproof construction of electric motor end cap screw hole comprises the end cap body, and bearing pedestal is protruded at the middle part of end cap body bottom surface downwards, and the end face arranged outside of end cap body has some boss, offers screw hole on the boss.
Above-mentioned described boss is arranged on the recess step in the end face outside of end cap body, boss and step side wall surface formation guiding gutter.
Above-mentioned described boss is annular.
Above-mentioned described some boss are 4, and the quantity of screw hole also is 4, is evenly distributed on the end cap body.
The beneficial effect of the utility model is: 1) the utility model is set up boss at end cap body end face; Boss and step wall have formed guiding gutter, and ponding will flow away from guiding gutter on the electric motor end cap, and boss plays a protective role; The composition surface that makes rainwater can not pass through screw and screw hole gets into motor internal; Effectively solve the hidden danger of screw hole water inlet, simple in structure, good water-proof effect; 2) boss is arranged on the recess step in the end face outside of end cap body, boss and step side wall surface formation guiding gutter, and reasonable in design effectively prevents the current motor internal; 3) some boss are 4, and the quantity of screw hole also is 4, are evenly distributed on the end cap body, and are stressed even.

Embodiment:
Below through specific embodiment and combine accompanying drawing that the utility model is described in further detail.
Like Fig. 3, Fig. 4 and shown in Figure 5; The utility model is a kind of waterproof construction of electric motor end cap screw hole, comprises end cap body 1, and bearing pedestal 2 is protruded at the middle part of end cap body 1 bottom surface downwards; The end face arranged outside of end cap body 1 has some boss 5, offers screw hole 4 on the boss 5; Boss 5 is arranged on the recess step 3 in the end face outside of end cap body 1, and boss 5 forms guiding gutter 6 with step 3 side wall surfaces; Described boss 5 is annular; Some boss 5 are 4, and the quantity of screw hole 4 also is 4, are evenly distributed on the end cap body 1.
The utility model is through setting up boss 5 at end cap body 1 end face; Boss 5 has formed guiding gutter 6 with the wall of the recess step 3 in the end face outside of end cap body 1, and ponding will flow away from guiding gutter 6 on the electric motor end cap, and boss 5 plays a protective role; Make rainwater can not pass through the entering motor internal of screw hole 4; Effectively solve the hidden danger of screw hole water inlet, simple in structure, good water-proof effect.
