Description
Technical field
The utility model relates to a kind of automobile pipeline structures, more particularly to a kind of crankcase that can detect exhaust gas discharge automatically
Snorkel.Belong to automobile pipeline component technology field.
Background technique
Crankcase breather is to utilize the vacuum in air inlet pipe for the connection between engine charge pipeline and crankcase
Degree extracts the exhaust gas in crankcase out, guarantees engine interior waste gas circulation, exhaust gas is prevented to be discharged into atmosphere.Existing ventilation
Pipe structure are as follows: have both threads beam, including two wire terminals and an electrical outlet, the both ends of snorkel in the outer surface of smooth tube
It is connector and valve respectively, has a boss on connector and valve body, have a locking hole inside boss, unifies with wire terminal group
It rises and is fixed on engine cylinder body, be electrified in electrical outlet, when engine operates normally, if wire terminal has loosening that will have
Alarm phenomenon is able to know that snorkel and engine air inlet tube or crankcase junction have gas leak phenomenon, so quickly in this way
Atmosphere pollution will be generated, emission request is not met, does not have people will not be allowed to discover gas leakage when harness in the past.With
Even if completing as long as being wrapped in process inside foamed glue toward harness, then main engine plants are in entrucking again by wire terminal and boss
It is fixed on engine cylinder body, is needed wire terminal alignment boss during installation so manually together by bolt after matching
Circular hole is locked by bolt again, i.e., in the case where increasing a procedure, improves the assembly time of vehicle, and work is by force
Degree.
Utility model content
Technical problem to be solved in the utility model is to provide one kind for the above-mentioned prior art to detect exhaust gas automatically
The crankcase breather structure of discharge can not only detect whether that exhaust gas is caused to discharge and lead to atmosphere pollution, simultaneously well
The assembly time of vehicle can be improved.
The technical scheme in the invention for solving the above technical problem are as follows: a kind of crankcase breather structure, including light
Slip pipe is respectively arranged with connector and valve at the both ends of the smooth tube, wherein being equipped in the connector side by fixing seat
Electrical outlet draws both threads beam in the electrical outlet, and both threads beam is respectively led into two end connectors and valve position of smooth tube, and
Wire terminal is respectively set in both threads beam end, it is convex with threaded hole that one is respectively arranged on the outside of the connector and valve
Platform, the threaded hole is interior will to be fixed on engine cylinder body by bolt together with wire terminal, be opened in the side of the boss
Equipped with a card slot, the tail portion of the wire terminal is embedded in card slot fixed.
Preferably, valve position will be led to by electrical outlet by forming one layer of polyurethane foaming layer in smooth tube surface blister
Harness wraps up.
Compared with the prior art, the advantages of the utility model are:
1, there is both threads beam in the outer surface of smooth tube, while including two wire terminals and an electrical outlet, wire ends
Son is fixed on engine cylinder body, is electrified in electrical outlet, when engine operates normally, if wire terminal has loosening that will go out
It now alarms phenomenon, is able to know that snorkel and engine air inlet tube or crankcase junction have gas leak phenomenon quickly in this way.
2, foam process is carried out using outer surface one circle of polyurethane (PUR) material to smooth tube, because material has thus
Optimal heat insulation, can guarantee that this snorkel works under high temperature environment will not deform.
3, a card slot is offered by the side in boss, the tail portion of wire terminal is embedded in card slot and is fixed, in this way
It may insure that wire terminal is always positioned on boss and is aligned with threaded hole, when installation can directly be bolted, and save
The process for being directed at wire terminal with threaded hole has been gone, the time of vehicle installation 10-15s is saved.
Detailed description of the invention
Fig. 1 is the structural schematic diagram in the utility model embodiment.
Wherein:
Smooth tube 1, connector 2, valve 3, fixing seat 4, electrical outlet 5, harness 6, wire terminal 7, polyurethane foaming layer 8, boss
9, card slot 10.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Figure 1, one of the present embodiment crankcase breather structure, including smooth tube 1, in the smooth tube 1
Both ends be respectively arranged with connector 2 and valve 3, wherein being equipped with electrical outlet 5, the electricity by fixing seat 4 in 2 side of connector
Both threads beam 6 is drawn on socket 5, both threads beam 6 is respectively led into 3 position of two end connectors 2 and valve of smooth tube 1, and at two
Wire terminal 7 is respectively set in 6 end of harness, will be by electric mortiser by forming one layer of polyurethane foaming layer 8 in 1 surface blister of smooth tube
The harness that mouth 5 leads to 3 position of valve wrap up, and it is convex with threaded hole to be respectively arranged with one in the outside of the connector 2 and valve 3
Platform 9, the threaded hole is interior will to be fixed on engine cylinder body together by bolt with wire terminal 7, in order to consolidate wire terminal 7
It is scheduled on the threaded hole of boss 9 and facilitates installation, offer a card slot 10, the tail of the wire terminal 7 in the side of the boss 9
Portion is embedded in card slot 10 and fixes, and may insure that wire terminal 7 is always positioned on boss 9 and is aligned with threaded hole in this way, installs
When can directly be bolted, eliminate the process for being directed at wire terminal with threaded hole, save vehicle and 10- is installed
The time of 15s.When electrical outlet is electrified, and engine operates normally, if wire terminal has loosening that will have alarm phenomenon, this
Sample is able to know that snorkel and engine air inlet tube or crankcase junction have gas leak phenomenon quickly, can thus generate atmosphere
Pollution, does not meet emission request.Foam process is carried out using outer surface one circle of polyurethane (PUR) material to smooth tube, is formed
Polyurethane foaming layer will lead to valve side harness wrap up, on the one hand can prevent harness exposure or by other component touching and
Fracture can guarantee this snorkel in hot environment on the other hand because polyurethane (PUR) material has optimal heat insulation
Lower work will not deform.
In addition to the implementation, the utility model further includes having other embodiments, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection scope of the utility model claims.
