Description
Technical field
The utility model relates to a kind of auto parts machinery, is specifically related to a kind of automobile air flow meter.
Background technology
At present, automotive engine air intake system being all equiped with air flowmeter usually, for accurately detecting the flow of air, enabling the work that engine electric spray system is high-quality and efficient, and then reduce engine consumption.The structure of automobile air flow meter mainly includes tubular shell and flowmeter bodies, described flowmeter bodies is installed on tubular shell, and be connected with the collection head extending to tubular shell inner chamber, one end of tubular shell is inlet end, the other end of tubular shell is outlet side, described inlet end is fixedly connected with air filter for automobile usually, in the prior art, all achieved a fixed connection by bolt and nut between the inlet end of tubular shell and air filter for automobile, but because air filter for automobile belongs to consumable accessory, change frequent, and each replacing all needs first to disassemble whole for bolt and nut, again load onto again, therefore dismounting extremely bothers.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the more convenient and data sampling automobile air flow meter more accurately of a kind of dismounting.
For achieving the above object, the utility model provides a kind of automobile air flow meter, include tubular shell and flowmeter bodies, described flowmeter bodies is installed on tubular shell, and be connected with the collection head extending to tubular shell inner chamber, one end of tubular shell is inlet end, the other end of tubular shell is outlet side, the air channel of a G font is provided with in the inner chamber of described tubular shell, the opening in described G font air channel is just to the inlet end port of tubular shell, the bottom in described G font air channel offers air outlet opening, described collection head is installed in G font air channel, and correspondence is positioned near described air outlet opening place, described tubular shell is being provided with near its inlet end port the flange extended radially outwardly, described flange is evenly distributed in the bindiny mechanism that at least two groups can be fixedly connected with air filter for automobile, Mei Zu bindiny mechanism has included a swing bolt, one locking bail and a nut, the end, one end of described swing bolt is one-body molded the fixing suspension ring that to be hinged with described flange, the other end end of described swing bolt is provided with external thread, described locking bail slip cap is loaded on swing bolt, and correspondingly on described locking bail be provided with one and can form hook with air filter for automobile and join fixing locking gib head, described nut screw is connected on the external thread of swing bolt, and corresponding formation is fixed the axial limiting of locking bail, the inlet end port of described tubular shell is also disposed with ground floor screen pack from inside to outside, second layer screen pack and third layer screen pack, described ground floor screen pack is boxwork, described second layer screen pack is grid-like grid, described third layer screen pack is vertical bar shape grid.
The beneficial effects of the utility model are: adopt said structure, during assembling, first by the slip of described locking bail on swing bolt, locking gib head hook on locking bail is joined and fixes air filter for automobile, then fastening nut, just automobile air flow meter and air filter for automobile can be made to form a fixed connection, and when needing after air filter for automobile damages to change, only nut need be unclamped a few circle, by the slip of described locking bail and swing bolt, locking gib head on described locking bail is lost with air filter for automobile be connected, just can rapidly air filter for automobile be disassembled, when again assembling, same only need first being joined by the locking gib head hook on locking bail fixes air filter for automobile, and just can then again be tightened by nut, compared to existing technology, disassembling, assembling and replacing is convenient.Meanwhile, due in disassembling, assembling and replacing process, described swing bolt, locking bail and nut are connected on tubular shell all the time, therefore also can effectively avoid above-mentioned part to go out active in disassembling, assembling and replacing process.In addition, because the utility model is provided with the air channel of a G font in the inner chamber of described tubular shell, and make the opening in described G font air channel just to the inlet end port of tubular shell, offer air outlet opening in the bottom in described G font air channel simultaneously, and described collection head is installed in G font air channel, and correspondence is positioned near described air outlet opening place, because the air flowing of this position is more natural, can not produce backflow phenomenon, the data of therefore sampling will be more accurate.And be also disposed with ground floor screen pack, second layer screen pack and third layer screen pack from inside to outside due to the inlet end port of described tubular shell, described ground floor screen pack is boxwork, described second layer screen pack is grid-like grid, described third layer screen pack is vertical bar shape grid, therefore by arranging the screen pack of multilayer difformity structure, more effectively can filter out and mixing aerial impurity.
The utility model can be set to also be provided with bulb pad between described locking bail and nut further, described bulb pad is connected and composed by a basal disc and a spherical plush copper, described bulb pad is set on swing bolt also corresponding between locking bail and nut, and described locking bail corresponding ball recess offered for the spherical plush copper embedding on described bulb pad on the outer face of nut.
Adopt said structure, be slidably matched by the sphere of spherical plush copper and locking bail ball recess on described bulb pad, can make the locking gib head on locking bail hook join fixing after, energy self-centering, keep swing bolt not by bending, reduce the bending stress of swing bolt, improve swing bolt intensity, thus greatly extend the serviceable life of bindiny mechanism.
