Abstract
The utility model discloses the attachment structure of a kind of dust cap and vehicle-mounted adapter, including rotating shaft, the side of the dust cap sets the axle sleeve coordinated with rotating shaft, the outer wall of axle sleeve is provided with arc-shaped limit boss, the position that the side of top one of the vehicle-mounted adapter corresponds to axle sleeve offers arc groove, the axis hole with the journal engagement of rotating shaft is offered on the wall at arc groove both ends, rotating shaft is loaded in axle sleeve, axle sleeve is positioned in arc groove, axle journal stretches out axle sleeve and inserted in the axis hole, arc-shaped limit boss and arc groove interference engagement and all the time against, frictional force between arc-shaped limit boss and arc groove enables dust cap to be stopped in any position uncapped.This attachment structure can save the exterior space of vehicle-mounted adapter, while be easy to the free grafting of plug to operate, and avoid to being interfered using equipment.
Description
Technical field
The utility model belongs to vehicle-mounted audio-visual system field, and in particular to the connection of a kind of dust cap and vehicle-mounted adapter
Structure.
Background technology
Be generally provided with vehicle-mounted adapter on the panel of automotive interior, have on vehicle-mounted adapter electrical equipment plug receptacle with
Be convenient for people to use electronic device works, charging etc..In order to prevent dust and other impurities from entering in plug receptacle, vehicle-mounted adapter is just
Face typically can all be provided with dust cap, remove dust cap during use and expose plug receptacle, cover dust cap again using after terminating
It is upper.
The dust cap of existing vehicle-mounted adapter typically uses screw-on or flexible glue interconnection system, and screw-on is will be dust-proof
Lid is arranged to circular configuration and screws in closing；Flexible glue interconnection system is that the side of dust cap is connected into vehicle-mounted adapter with flexible glue
On, with the socket that achieves a butt joint expose or " locked in " operation.There can not be convex barrier around the dust cap of screw-on, it is empty to compare occupancy
Between, and meeting free-falling in its free end after unlatching of the dust cap of flexible glue interconnection system, it has not been convenient to the free grafting of plug, can be right
Interfered using equipment, inconvenience is brought to operation.
The content of the invention
The purpose of this utility model is to provide the attachment structure of a kind of dust cap and vehicle-mounted adapter, to save vehicle-mounted switching
The exterior space of device, while it is easy to the free grafting of plug to operate, avoid to being interfered using equipment.
The attachment structure of dust cap described in the utility model and vehicle-mounted adapter, including rotating shaft, the one of the dust cap
Side sets the axle sleeve coordinated with rotating shaft, and the outer wall of axle sleeve is provided with arc-shaped limit boss, the top side of the vehicle-mounted adapter
The position that side corresponds to axle sleeve offers arc groove, is offered on the wall at arc groove both ends and the journal engagement of rotating shaft
Axis hole, loaded in axle sleeve, axle sleeve is positioned in arc groove for rotating shaft, and axle journal stretches out axle sleeve and inserted in the axis hole, makes dust-proof
Lid is connected on vehicle-mounted adapter, and arc-shaped limit boss is with arc groove interference engagement and all the time against convex by arc-shaped limit
Frictional force between platform and arc groove can be such that dust cap is stopped in any position uncapped without independently hanging down.
The rotating shaft is spring shaft, and spring is provided with its axis body, and one end of the axle journal is stretched into axis body to be supported with spring
Lean on, axle journal can extend or shorten relative to axis body（The other end of axle journal is acted on hand, can by axle journal compression spring
Axle journal is shortened relative to axis body, after unclamping hand, spring return function, axle journal can be made to be extended relative to axis body）, so that axle journal inserts
Axis hole is more convenient.
Preferably, the arc-shaped limit boss and the amount of interference of arc groove interference engagement are 0.1~0.2mm.
The utility model has the effect that：
（1）Dust cap can stop in any position uncapped, and without independently hanging down, dust cap will not be to week when opening
Side member impacts, and so as to save the exterior space of vehicle-mounted adapter, while also allows for the free grafting operation of plug,
Will not be to being interfered using equipment.
（2）Rotating shaft uses spring shaft, and installation is more convenient, is quick.
Brief description of the drawings
Fig. 1 is decomposing schematic representation of the present utility model.
Fig. 2 is the structural representation of the rotating shaft in the utility model.
Fig. 3 is the structural representation that dust cap is connected on vehicle-mounted adapter.
Embodiment
The utility model is elaborated below in conjunction with the accompanying drawings.
The attachment structure of dust cap as shown in Figure 1, Figure 2, Figure 3 shows and vehicle-mounted adapter, including rotating shaft 2, rotating shaft 2 are spring
Axle, is provided with spring 23 in the axis body 22 of rotating shaft 2, and one end of the axle journal 21 of rotating shaft 2 is stretched into axis body 22 with spring 23 against axle
Neck 21 can extend or shorten relative to axis body 22；The side of dust cap 1 is integrally formed with the axle sleeve 11 coordinated with rotating shaft 2, axle
The outer wall of set 11 has electrical equipment jointing holes 33, AUX jacks 34 integrally formed with two arc-shaped limit boss 12, vehicle-mounted adapter 3,
The position that the side of top one of vehicle-mounted adapter 3 corresponds to axle sleeve 11 offers arc groove 31, the wall at the both ends of arc groove 31
The axis hole 32 coordinated with axle journal 21 is offered on face, rotating shaft 2 is loaded in axle sleeve 11, and axle sleeve 11 is positioned in arc groove 31, axle
Neck 21 stretches out axle sleeve 11 and inserted in axis hole 32, dust cap 1 is connected on vehicle-mounted adapter 3, arc-shaped limit boss 12 and arc
The interference engagement of connected in star 31（Amount of interference is 0.15mm）, arc-shaped limit boss 12 and arc groove 31 are all the time against passing through arc
Frictional force between positive stop lug boss 12 and arc groove 31 can make dust cap 1 0~120 ° of any position uncapping stop without
Can independently it hang down, for example dust cap 1 is opened to 30 °（That is dust cap 1 and the angle of the vehicle-mounted upper surface of adapter 3 is 30 °）When, prevent
Dirt lid 1 can be stopped in this position without hanging down, when dust cap 1 is opened to 60 °, dust cap 1 can stop this position without
Hang down, dust cap 1 will not be to being interfered using equipment.
