Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in detail embodiment of the present utility model below in conjunction with accompanying drawing.Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar improvement without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, pipe connecting structure of the present utility model comprises: the first pipeline 1; And the second pipe 2 to socket-connect with described first pipe 1, wherein, socket end 11 cover of described first pipeline 1 is received in the socket end 21 of described second pipe 2; Wherein, the internal surface that described second pipe 2 is socketed end 21 is formed with limit structure 22, this limit structure 22 is received when second pipe 2 is socketed in end 21 and is supported for being socketed end 11 cover at the first pipeline 1 end face 111 that described first pipeline 1 is socketed end 11; And described second pipe 2 is socketed end 21 to be had and extends to the elasticity briar tooth 23 that this second pipe 2 is socketed the inside of end 21, this briar tooth 23 is located at the position of the end face being socketed end 21 for described limit structure 22 closer to second pipe 2, for be socketed at the first pipeline 1 end 11 cover receive second pipe 2 be socketed in end 21 time, with be located at described first pipeline 1 and be socketed hook element 12 hook on the outer surface of end 11, be socketed end 11 to prevent the first pipeline 1 and be socketed end 21 from second pipe 2 and exit.
In the present embodiment, the wall that described second pipe 2 is socketed end 21 is provided with and is communicated with the through hole 24 that this second pipe 2 is socketed the inside and outside surface of end 21, described briar tooth 23 has and reaches by described through hole 24 the release end 233 that described second pipe 2 is socketed outside, end 21, this release end can be operated to remove hooking together between described briar tooth 23 and described hook element 12, makes the first pipeline 1 be socketed end 11 and can be socketed end 21 from second pipe 2 and exit.
In the present embodiment, as illustrated in fig. 1 and 2, described briar tooth 23 is elastic V shaped part, and this elastic V shaped part has the first leg 231, point 232 and the second leg 233 that are connected successively.The upper end of described first leg 231 is fixed to the outer surface that described second pipe 2 is socketed end 21, described through hole 24 is extended downwardly through from this outer surface, the described point 232 be connected with this first leg 231 is made to arrive the inside of described second pipe 2 and be positioned at the below of described through hole 24, simultaneously, described second leg 233 be connected with described point 232 upwards extends, extends to outside by described through hole 24, becomes release end.Optionally, described first leg 231 also can be fixedly attached to the internal surface of described socket end 21 or the hole wall of described through hole.
In the present embodiment, described hook element 12 is for being formed in the projection on the outer surface of described first pipeline socket end, described projection has the mating face and the inclined-plane relative with this mating face that engage with described first pipeline 1, described inclined-plane tilts along the direction pointing to the first pipeline 1 from second pipe 2, and described inclined-plane is formed with recess, when the socket end 11 of the first pipeline 1 cover is received in the socket end 21 of second pipe 2, the point 232 of described briar tooth 23 is positioned in described recess, thus makes briar tooth 23 and hook element 12 hook.In an alternate embodiment, described hook element 12 also can be other form, such as, is formed in the first pipeline 1 and is socketed depression in end outer surface, that be suitable for hooking point 232.In another alternate embodiment, described projection also can be cuboid or cube or irregularly shaped, as long as it has and the depression hooking described briar tooth point.
In the present embodiment, described limit structure 22 is socketed step surface on the internal surface of end 21 for being formed in described second pipe 2.In an alternate embodiment, described limit structure 22 can be other form, such as, be formed in second pipe 2 and be socketed one or more pillar or protuberance etc. on the internal surface of end 21.
In the present embodiment, when the first pipeline 1 and second pipe 2 link together by needs, only the socket end 11 of the first pipeline 1 need be advanced in the socket end 21 of second pipe 2, when hook element 12 be advanced to contact with shackle link tooth 23 time, shackle link tooth 23 incites somebody to action roughly radial outward movement under the thrust on the above-mentioned inclined-plane from hook element 12, then decline gradually against inclined-plane, finally hook together in the recess of hook element 12; Meanwhile, the end face 111 of the socket end 11 of the first pipeline 1 arrives step surface 22 place be formed on the internal surface of the socket end 21 of second pipe 2, and push against this step surface 22, thus realize the first pipeline 1 and be socketed end 11 and be socketed firm socket in end 21 at second pipe 2.On the other hand, when needing the first pipeline 1 connected and second pipe 2 to split, only need along the axis of orientation in figure shown in arrow A to the second leg 233 promoting described shackle link tooth 23, described point 232 can be driven to move upward, and then depart from the recess of described hook element 12, thus the socket end 11 of described first pipeline 1 can be exited from the socket end 21 of second pipe 2.
Described elastic V shaped part can be made up of steel elastic material or plastic elastic material.Preferably, described elastic V shaped part is anticorrosive by stainless steel, manganese steel, titanium steel etc., high temperature resistance elastic material is made, or described elastic V shaped part is that plastic elastic material is made, socket end 21 integrated injection molding of itself and described second pipe 2.
In the present embodiment, described pipe connecting structure also comprises seal ring 3, and sealing circle 3 is located in the groove 25 on the internal surface being located at described second pipe 2, and this groove 25 is located axially at the position between described briar tooth 23 and described step surface 22.The application of described seal ring 3 can realize being tightly connected more reliably between the first pipeline 1 and second pipe 2.Optionally, groove for locating described seal ring also can be located at the outer surface of described first pipeline 1, when the first pipeline 1 be socketed end 11 cover receive second pipe 2 be socketed in end 21 time, described seal ring and the position of described groove between described briar tooth and described limit structure.
Fig. 3 is for schematic diagram during air-strainer according to the pipe connecting structure of the utility model embodiment.As shown in Figure 3, in actual use, first the air-strainer 10 with the first pipeline 1 can be mounted to body side (not shown), by hooking together (see Fig. 1 and Fig. 2) of the briar tooth 23 of the hook element of the first pipeline 1 12 and second pipe 2, first pipeline 1 is socketed in second pipe 2, thus realize air-cleaner snorkel road simple, be fixedly connected with reliably.Change pipeline at needs or when removing air-strainer, only need operate the corresponding part of briar tooth, can easy removal be realized.Known above, simple, easy and simple to handle according to the structure of pipe connecting structure of the present utility model, and firm, reliable, the good airproof performance between two pipelines can be realized, and dismountable connection.
Above only describes a kind of embodiment of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
