Abstract
The invention discloses a connecting flange assembly. The connecting flange assembly comprises a first flange body and a second flange body; the bottom surface of the first flange body is provided with a first through hole and a first blind hole; the bottom surface of the second flange body is provided with a second through hole and a second blind hole; the diameter of the first through hole is smaller than that of the second through hole; the diameter of the first blind hole is as same as that of the second blind hole; a mistake proofing groove is horizontally formed in the top surface of the first flange body; the mistake proofing groove is located between the first through hole and the first blind hole. According to the connecting flange assembly, the first flange body is provided with the mistake proofing groove and accordingly a mistake during installation can be avoided so as to distinguish the two flange bodies.
Description
Technical field
The present invention relates to a kind of connecting flange assembly, particularly a kind of connecting flange assembly of car air conditioner refrigerant pipeline.
Background technique
Air conditioner coolant pipeline in automobile industry all has two connecting flanges, one is positioned at liquid entering hole position, and another is positioned at liquid outlet position.The design of two connecting flanges and section bar used are all identical, the cost of manufacture can be reduced like this, be convenient to produce in enormous quantities, just there is difference at the diametrically in hole, be easy to like this occur setup error in installation process, two connecting flanges are mixed up, makes troubles to follow-up work.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of connecting flange assembly, conveniently can distinguish to reach, avoiding the object of misloading.
For achieving the above object, technological scheme of the present invention is as follows:
A kind of connecting flange assembly, comprise the first flange body and the second flange body, the bottom surface of described first flange body is provided with through hole one and blind hole one, the bottom surface of described second flange body is provided with through hole two and blind hole two, the diameter of described through hole one is less than the diameter of described through hole two, described blind hole one is identical with described blind hole two, and the end face of described first flange body is laterally provided with a mistake proofing groove, and described mistake proofing slot is between described through hole one and described blind hole one.
Preferably, the bottom surface of described first flange body and the second flange body is umbilicate arc surface.
Preferably, the top of described through hole one and described through hole two is laterally provided with the mounting hole that passes described through hole one and through hole two.
Preferably, described through hole one is less than diameter near bottom surface near the diameter of described first flange body end face.
Preferably, described through hole two is less than diameter near bottom surface near the diameter of described second flange body end face.
Pass through technique scheme, connecting flange assembly provided by the invention, laterally a mistake proofing groove is provided with at the end face of the first flange body, the design of this mistake proofing groove does not affect the usability of flange body, and can significantly distinguish two flange body, prevent misloading, be conducive to improving the efficiency of installing, avoid the trouble again dismantled.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below.
Fig. 1 is the side view of the first flange body disclosed in the embodiment of the present invention;
Fig. 2 is the plan view of the first flange body disclosed in the embodiment of the present invention;
Fig. 3 is the side view of the second flange body disclosed in the embodiment of the present invention;
Fig. 4 is the plan view of the second flange body disclosed in the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described.
The invention provides a kind of connecting flange assembly, the first flange body in this connecting flange assembly is provided with mistake proofing groove, and the mistake occurred when can avoid installing, improves installation efficiency.
As shown in figures 1 and 3, described connecting flange assembly, comprise the first flange body 1 and the second flange body 2, the bottom surface of the first flange body 1 is provided with through hole 1 and blind hole 1, the bottom surface of the second flange body 2 is provided with through hole 25 and blind hole 26, and the diameter of through hole 1 is less than the diameter of through hole 25, and blind hole 1 is identical with blind hole 26, the end face of the first flange body 1 is laterally provided with a mistake proofing groove 7, and mistake proofing groove 7 is between through hole 1 and blind hole 1.
In the present embodiment, the bottom surface of the first flange body 1 and the second flange body 2 is umbilicate arc surface, fails to show in figure; The top of through hole 1 and through hole 25 is laterally provided with the mounting hole 8 that passes through hole 1 and through hole 25, for installing; As can be seen from Fig. 1 and Fig. 3, through hole 1 is less than the diameter near bottom surface near the diameter of the first flange body 1 end face, and through hole 25 is less than the diameter near bottom surface near the diameter of the second flange body 2 end face.
As can be seen from Fig. 2 and Fig. 4, the first flange body 1 and the second flange body 2 are the round and smooth body of the cylinder docking that two differ in size, and lines are soft, can avoid damaging workman when installing.
Connecting flange assembly provided by the invention, laterally a mistake proofing groove is provided with at the end face of the first flange body, the setting of this mistake proofing groove does not affect the usability of flange body, and can significantly distinguish two flange body, prevent misloading, be conducive to improving the efficiency of installing, avoid the trouble again dismantled.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
