It will be understood that when an element is referred to as being "mounted" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," "upper," "lower," and the like are used herein for descriptive purposes only and not to indicate or imply that the apparatus or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.
In the present invention, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a first embodiment of the present invention proposes a vent pipe connector for connecting with a male connector 3 of an engine, wherein a boss 31 is provided at the end of the male connector 3, the vent pipe connector comprises a connector body 1 and a ferrule 2, the ferrule 2 is sleeved on the connector body 1, when the male connector 3 is connected with the vent pipe connector, the male connector 3 is located between the connector body 1 and the ferrule 2, a barb 23 is provided on the inner surface of the ferrule 2, the barb 23 is used for being engaged with the boss 31, a sealing ring 11 is provided at one end of the outer surface of the connector body 1 close to the ferrule 21, and the sealing ring 11 is used for being in extrusion contact with the male connector 3.
In this embodiment, the ferrule 2 includes a clamping portion 21 and a fixing portion 22, the clamping portion 21 is of a tubular structure, the barb 23 is disposed on an inner wall of the clamping portion 21, the fixing portion 22 is of an annular plate structure, and the fixing portion 22 is fixedly connected with the clamping portion 21 and the connector body 1 at the same time.
It should be noted that, the boss 31 and the barb 23 are both made of plastic, and can be elastically deformed to a certain extent, and the boss 31 can enter between the clamping portion 21 and the joint main body 1 by extruding the barb 23; when the boss 31 is completely in, the barb 23 can reset, and at the moment, the barb 23 can prop against the boss 31, and the male connector 3 cannot be pulled out, so that fixed connection is realized.
The invention has the advantages that the male connector 3 can be directly inserted into the ventilation pipe connector during assembly, the barb 23 clamps the male connector 3 at the moment and can not be pulled out, thereby realizing quick installation and simple assembly.
Referring to fig. 4, specifically, the barb 23 is a plate structure obliquely disposed in the ferrule 2, and a plurality of open slots 231 are formed at the edge of the barb 23.
It will be appreciated that the open slot 231 can reduce the strength of the barb 23, further increasing the ability of the barb 23 to deform, facilitating passage of the boss 31.
In addition, the end of the connector body 1 remote from the ferrule 2 is provided with 2 annular ribs 14, the annular ribs 14 being intended to be in contact with the ventilation tube.
It should be noted that the ventilation pipe can be adhered to the surface of the connector body 1, or the ventilation pipe can be sleeved on the connector body 1 and then bound and fixed by using a metal wire, and the annular rib 14 improves the fixing effect between the ventilation pipe and the connector body 1. And because of the existence of the annular convex rib 14, after the vent pipe is fixed, the annular convex boss 14 can form a sealing ring, so that the air tightness between the vent pipe and the joint main body 1 is enhanced.
Referring to fig. 3, specifically, the outer surface of the connector body 1 is provided with a stop collar 15, the stop collar 15 is used for being matched with the barb 21 to fix the boss 31, the outer surface of the connector body 1 is provided with an elastic ring 13 near the stop collar 15, and the elastic ring 13 is used for extruding with the tail end of the male connector 3.
It should be noted that the elastic ring 13 can have a certain buffer effect, preventing the male connector 3 from damaging the ventilation pipe connection by too much force during insertion;
in addition, under the limited condition of production conditions, the production precision of the barb 23 and the limiting ring 15 can not be achieved, and the barb 23 and the limiting ring 15 can not well clamp the boss 31, so that a certain gap exists between the barb 23 and the limiting ring 15 and the male connector 3 after the male connector 3 is assembled, and the gap can cause relative displacement between the male connector and the vent pipe connector to influence the air tightness of connection.
In order to improve the air tightness, the elastic ring 13 can push the male connector 3 in the opposite direction after the male connector 3 is mounted, so that the connection between the male connector 3 and the ventilation pipe joint is more stable, and the air tightness is improved.
In this embodiment, the elastic ring 13 is provided with an annular cavity inside, and the annular cavity is filled with gas. In other embodiments, the annular cavity may also be filled with springs, such as small springs.
Preferably, when the male connector 3 is assembled, the male connector 3 is in a pressed state with the elastic ring 13.
In addition, the joint body 1 is provided with an annular groove 12 at the sealing ring 11, the sealing ring 11 is disposed in the annular groove 12, and the clamping portion 21 and the fixing portion 22 are respectively provided with a first mounting groove 211 and a second mounting groove 221.
The first mounting groove 211 and the second mounting groove 221 can facilitate the fixing of the ventilation pipe in the automobile.
Referring to fig. 5 and 6, further, a positioning block 16 is disposed at a connection portion between the limiting ring 15 and the fixing portion 22, a positioning groove 222 is disposed on an inner wall of the fixing portion 22 facing the positioning block 16, and the positioning block 16 is disposed in the positioning groove 222.
In this embodiment, the positioning block 16 has 4 block structures arranged around the connector main body 1, and the positioning groove 222 is a plurality of grooves uniformly formed on the inner wall of the fixing portion 22, so that the positioning block 16 and the positioning groove 222 can facilitate the early assembly of the ventilation pipe connector.
A second embodiment of the invention proposes a crankcase comprising at least the vent coupling of the first embodiment.
In the description of the present specification, a description referring to terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the present invention. In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
