Abstract
Lamp body sealing detection inflation mechanism is related to a kind of airtight plugging mechanism, solves the problems, such as existing detection lamp housing sealing detection, including inflation mechanism and propulsive mechanism；The inflation mechanism includes sealing leather packing, air inlet core and breather valve；Propulsive mechanism is formed by cylinder and from the pedestal for fixing cylinder of processing；The sealing leather packing extruding is mounted in air inlet core slot, and breather valve is tightened with air inlet core by screw thread；Air inlet core bottom is tightened by threaded hole and cylinder, and cylinder bottom is fixedly connected on cylinder block.The utility model has the beneficial effects that airtight plugging mechanism described in the utility model is to realize position displacement by driving unit of cylinder, then realize confined space pressure maintaining in car light port by breather valve air inlet using gas as driving force.
Description
Technical field
The utility model relates to a kind of airtight plugging mechanisms, and in particular to a kind of lamp body sealing detection inflation mechanism.
Background technique
During automobile lamp is assembled in production, need after car light outer shield and lamp housing sealing assembly, verifying is whole close
Effect is sealed, the package seal checker that harness mouth under lamp housing is detected under standing state has no existing molding detection air charging system, makes
It obtains the detection of car light inner sealing and is unable to get effective solution,
Utility model content
The utility model provides a kind of lamp body sealing detection and fills to solve the problems, such as existing detection lamp housing sealing detection
Mechanism of qi structure.
Lamp body sealing detection inflation mechanism, including inflation mechanism and propulsive mechanism；The inflation mechanism includes sealing
Leather packing, air inlet core and breather valve；Propulsive mechanism is formed by cylinder and from the pedestal for fixing cylinder of processing；
The sealing leather packing extruding is mounted in air inlet core slot, and breather valve is tightened with air inlet core by screw thread；
Air inlet core bottom is tightened by threaded hole and cylinder, and cylinder bottom is fixedly connected on cylinder block.
The utility model has the beneficial effects that airtight plugging mechanism described in the utility model is using gas as driving force, with gas
Cylinder is that driving unit realizes position displacement, then confined space pressure maintaining in car light port is realized by breather valve air inlet.
Airtight closure mechanism structure described in the utility model is simple, it is only necessary to provide air inlet power output.Using more
Simplify structure to realize more easily mode of operation, and it is more preferable to detect using effect.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of lamp body sealing detection inflation mechanism described in the utility model；
Fig. 2 is the structural decomposition diagram of lamp body sealing detection inflation mechanism described in the utility model.
Specific embodiment
Specific embodiment one illustrates present embodiment, lamp body sealing detection inflation mechanism, packet in conjunction with Fig. 1 and Fig. 2
Include inflation mechanism 1 and propulsive mechanism 2；The propulsive mechanism that the inflation mechanism bottom connection cylinder is constituted.The inflation mechanism by
Leather packing is sealed, 1-1 air inlet core 1-3 (workpiece), breather valve 1-2 are assembled into, and sealing leather packing 1-1 extruding is placed in air inlet core
In 1-3 slot, breather valve 1-2 carries screw socket and mutually tightens with air inlet core 1-3；
The bottom air inlet core 1-3 is that threaded hole is tightened with cylinder 2-1 in the inflation mechanism, cylinder bottom connection processing aluminium
Seat is integrally fixed using screw.
The working principle of airtight plugging mechanism described in present embodiment are as follows:
The driving of pusher cylinder is imported by gas first to realize that the displacement of air inlet core promotes air inlet core in car light port；
It is flowed by gas by breather valve and is flowed into car light port by blow vent core again；
The gas for injecting confined space in car light port is realized into pressure maintaining within the time of customer requirement, then proves car light gas
Mouth leakproofness no problem.
