Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of filtering breather plug, particularly a kind of cracking pressure can regulate, filtering breather plug that filter precision can be selected.
Background technique
In common breather plug device, spool generally uses steel ball or sheet rubber, and structure is simple and crude, degraded performance, and they have a common problem, is exactly that cracking pressure is unadjustable, and does not have filtering function, cannot dust-proof, waterproof.But filtering breather plug is indispensable again in some applications, such as: on automobile drive axle, speed changer and other closed box.In reality is produced, due to many-sided reasons such as product batch, price competitions, the performance of common breather plug device is often difficult to the expectation reaching user, shows that designing technique does not pass a test, and cracking pressure is unadjustable, cannot dust-proof, waterproof.So related domain needs the design proposal of a kind of filtering breather plug filtering breather plug that particularly cracking pressure can regulate, filter precision can be selected badly at present, to ensure that product can meet the usage requirement of user completely.
Summary of the invention
The purpose of this utility model is to solve prior art Problems existing, provides the filtering breather plug that a kind of rational in infrastructure, easy to adjust and filter precision can be selected.
For achieving the above object, technical solution of the present utility model is: a kind of filtering breather plug, comprise housing (1), elastic element (2), spool (3), filter element (4), fixed element (5) and regulating element (6), housing is provided with screw thread in (1), housing (1) is connected with regulating element (6) by screw thread, housing (1) one end is provided with regulating element (6), elastic element (2) and spool (3) form sealing pair, elastic element (2) one end is connected with spool (3), elastic element (2) the other end is connected with regulating element (6), lockable between regulating element (6) and housing (1), housing (1) the other end is provided with filter element (4), filter element (4) top is provided with fixed element (5), housing (1), filter element (4), fixed element (5) forms filter cleaner, housing (1) is provided with radial inclined hole (7) for exhaust.
Regulating element (6) is connected locked by screw thread fastening glue with housing (1).
Be provided with between regulating element (6) and housing (1) that to paint class locked.
It is locked that regulating element (6) and housing (1) carry out punching point.
Compared with prior art, the beneficial effect that the utility model has is: filtering breather plug a kind ofly plays an important role in the car and have the product of superperformance, under identical boundary dimension condition, adopt the design proposal that the utility model provides, the cracking pressure of filtering breather plug can regulate, filter precision can be selected; Filtering breather plug can accomplish dust-proof, waterproof; Filtering breather plug rational in infrastructure, easy to adjust, effectively can prevent the unexpected inefficacy of common breather plug device.At present, the design proposal of this kind of filtering breather plug, be applicable to various automotive applications, product performance meet the usage requirement of user completely.
Accompanying drawing explanation
Accompanying drawing is the structural representation of the utility model specific embodiment.
Embodiment
Below with reference to accompanying drawing, the utility model content is described further, but practical application structure of the present utility model is not limited in embodiment shown in the drawings.
See accompanying drawing, a kind of filtering breather plug described in the utility model comprises housing 1, elastic element 2, spool 3, filter element 4, fixed element 5, regulating element 6 etc.Be provided with screw thread in housing 1, housing 1 is connected with regulating element 6 by screw thread, and housing 1 one end is provided with regulating element 6, elastic element 2 and spool 3 and forms sealing pair, and belong to motive sealing, its cracking pressure can regulate; Elastic element 2 one end is connected with spool 3, and spool 3 is composited by different materials.Elastic element 2 the other end is connected with regulating element 6, produces different pressure by the advance and retreat of regulating element 6 to elastic element 2, the pressure of adjustable spool 3.After the cracking pressure of filtering breather plug mixes up, lockable between regulating element 6 and housing 1, in order to avoid in use pressure changes, regulating element 6 is connected locked by screw thread fastening glue with housing 1.Or be provided with between regulating element 6 and housing 1 that to paint class locked.Or it is locked that regulating element 6 and housing 1 carry out punching point.Or it is locked to adopt other mechanical measures.Housing 1 the other end is provided with filter element 4, and filter element 4 top is provided with fixed element 5, and housing 1, filter element 4, fixed element 5 form filter cleaner, and its filter precision is selected by selecting the filter element 4 of different filter precision; Housing 1 is provided with radial inclined hole 7 for exhaust.
During design, cracking pressure as requested can calculate the design parameter determining elastic element 2, can the different trades mark of filter precision choose reasonable filter element 4 as requested.
In real work, this kind of filtering breather plug can be arranged on automobile drive axle, speed changer and other closed box.
