Installation effectiveness.
A kind of electromotor rubber air inlet pipe described in the utility model seals structure, including rubber with the connection of pipe joint
Air inlet pipe and the pipe joint being connected with it, is characterized in that: described rubber air inlet pipe be provided with one communicate therewith hollow
The frustum of a cone, the inner surface of this open circles frustum is provided with anticreep groove；It is dentation that the outer surface of described pipe joint is provided with multi-turn
Seal convexity；The outer surface of described pipe joint and the inner surface interference fit of described open circles frustum.
Further, the outer surface of described pipe joint is additionally provided with the anticreep projection that a circle is annular, and described anticreep is protruding
Between said two seal convexity and with the anticreep groove corresponding matching of described open circles frustum inner surface.
Further, the height of described seal convexity is the twice of open circles frustum and the pipe joint magnitude of interference.
Further, described anticreep groove minimum point is more than or equal to described to the distance of described open circles frustum outer surface
Ten times of open circles frustum and the pipe joint magnitude of interference.
Further, four times that height is open circles frustum and the pipe joint magnitude of interference of described anticreep projection.
The technique effect that this utility model is useful:
Protruding owing to designing anticreep on open circles frustum, pipe joint designs anticreep groove, it is relative to existing
Technology decreases the use of anchor ear；Sealing effectiveness and anticreep is good, low cost；Meanwhile, improve production and installation effectiveness.

Detailed description of the invention
With preferred embodiment, this utility model is further described below in conjunction with the accompanying drawings.
A kind of electromotor rubber air inlet pipe shown in Figure 2 seals structure with the connection of pipe joint, enters including rubber
Trachea 4 and the pipe joint 5 being connected with it, its substantive distinguishing features is:
Described rubber air inlet pipe 4 is provided with an open circles frustum 41 communicated therewith, the inner surface of this open circles frustum 41
It is provided with anticreep groove 42；The outer surface of described pipe joint 5 is provided with the seal convexity 51 that three circles are dentation；Described pipe joint 5
The inner surface interference fit of outer surface and described open circles frustum 41.In the present embodiment, open circles frustum 41 is located at rubber and enters
The right part of trachea 4, can be located at any part of rubber air inlet pipe 4 as required.
Seeing Fig. 2 or Fig. 3, the outer surface of described pipe joint 5 is additionally provided with the anticreep projection 52 that a circle is annular, described
Anticreep projection 52 is enclosed between seal convexity at the second circle seal convexity and the 3rd from left to right, described anticreep protruding 52 and institute
State anticreep groove 42 corresponding matching of open circles frustum 41 inner surface.Owing to devising anticreep at the inner surface of open circles frustum 41
Groove 42, the outer surface at pipe joint 5 devises anticreep groove 42 so that good anti-drop effect, relative to prior art, reduces
The use of anchor ear.
The height of described seal convexity 51 is the twice of open circles frustum 41 and pipe joint 5 magnitude of interference.
Described anticreep groove 42 minimum point is more than or equal to described sky to the distance of described open circles frustum 41 outer surface
Ten times of the heart frustum of a cone 41 and pipe joint 5 magnitude of interference.
The height of described anticreep projection 52 is four times of open circles frustum 41 and pipe joint 5 magnitude of interference.
See Fig. 2, Fig. 3, Fig. 4, it is assumed that the internal diameter of open circles frustum 41 is c, open circles frustum 41 and the mistake of pipe joint 5
The amount of being full of is a, and the external diameter b of pipe joint 5 should be c+2a, and the height of seal convexity 51 is designed as 2a, and the height of anticreep projection 52 sets
Be calculated as 4a, anticreep groove 42 minimum point to described open circles frustum 41 outer surface away from more than or equal to 10a；Empirical tests, this
Sample design sealing and anticreep effectiveness comparison good, anticreep groove 42 minimum point to described open circles frustum 41 outer surface vertical away from
More than or equal to 10a, its objective is to ensure that open circles frustum 41 has enough thickness.
This utility model decreases the use of anchor ear relative to prior art；Sealing effectiveness and anticreep is good, low cost；With
Time, it is possible to increase produce and installation effectiveness.
