Description
Technical field
This utility model is related to the well lid of locking mechanism, specifically one well lid with inclined-plane retaining mechanism.
Background technology
Well lid of the prior art automobile quickly through when produce bounce, in order to overcome the defect, well lid and well seat it
Between adopt three-jaw clip spring structure, well lid is in clamping connection by frictional force with well seat using the elasticity of jump ring, this kind of structure
Have the disadvantage that jump ring and the magnitude of interference on well seat clamping inclined-plane are difficult control, job site also has no idea to adjust completely, and the magnitude of interference is big
Install laborious, well lid is difficult to close, during unlatching, staff is difficult to open, if especially after corrosion of metal. the magnitude of interference is little,
Not enough, anti-jumping effect is bad to be also easy to produce hot-tempered sound to jump ring crush.
The content of the invention
To overcome deficiencies of the prior art, the purpose of this utility model to be to provide a kind of band inclined-plane retaining mechanism
Well lid.
The technical scheme for adopting for achieving the above object is such, i.e., a kind of well lid with inclined-plane retaining mechanism, bag
The well lid for including well seat and coordinating with well seat；It is characterized in that：Well lid is at well seat with least one lock for being provided with screw hole
Tight screw rod mounting seat, the lower end of each tie down screw be provided with can with the locking arm of tie down screw synchronous rotary, the two of locking arm
End has mobile inclined-plane respectively, two movement inclined-planes with tie down screw to a direction rotate when, wherein a movement inclined-plane and being arranged on
The lower inclined plane latch segment of well seat inwall is locked, another mobile inclined-plane be arranged on it is another oblique under tie down screw mounting seat
Face latch segment is locked；Two movement inclined-planes with tie down screw to another direction rotate when, it is described to lock status releasing.
Further, it is another under the latch segment and the tie down screw mounting seat of the above-mentioned lower inclined plane for being arranged on well seat inwall
Once inclined-plane latch segment is plastics skewback.
This utility model drives locking arm rotation by tie down screw, by two inclined-planes on locking arm, respectively with well
Lower inclined plane block or unit of plastic inclined-plane on lid and well seat forms frictional fit, and well lid and well seat are carried out locking company by locking arm
Connect, the tie down screw anglec of rotation is bigger, and frictional force is bigger, and coupling mechanism force is bigger, as long as tie down screw is reversely rotated during unlatching, you can
Unclamp the inclined-plane of lock frictional fit locking., while acquisition reliable lock effect is good, locking and unblock are all for this utility model
Easily.

Specific embodiment
Referring to accompanying drawing：The well lid 1 that well lid with inclined-plane retaining mechanism in figure is included well seat 2 and coordinated with well seat；Its feature
It is：Well lid is at well seat with least one tie down screw mounting seat for being provided with screw hole, the lower end of each tie down screw 4
It is provided with and can has mobile inclined-plane respectively with the locking arm 5 of tie down screw synchronous rotary, the two ends of locking arm, two movement inclined-planes is with lock
Tight screw rod to a direction rotate when, wherein a movement inclined-plane is locked with the lower inclined plane latch segment for being arranged on well seat inwall,
Another mobile inclined-plane is locked with another lower inclined plane latch segment being arranged under tie down screw mounting seat；Two movement inclined-planes are with lock
Tight screw rod to another direction rotate when, it is described to lock status releasing.
Preferably, it is another under the latch segment with lower inclined plane for being arranged on well seat inwall and the tie down screw mounting seat
Once inclined-plane latch segment is plastics skewback.
Further, plastic sheath 7 and sealing ring 8 are installed on the body of rod of the tie down screw.
The tie down screw 4 passes through spline fitted, or the tie down screw and locking arm stage casing with the hole in 5 stage casing of locking arm
For many side columns and corresponding interior how lateral opening cooperation.Fig. 4, the tie down screw 4 shown in 5 are coordinating Duan Weisi side columns, lock with locking arm 5
Hole on tight arm is interior Quadrilateral zone.
Further, the nut that the screw hole in tie down screw mounting seat has heavy platform, tie down screw is located in heavy platform.Lock
Spring washer and disk plain cushion are lined with the nut of tight screw rod.The lower end of tie down screw is set with spring washer and disk plain cushion, and will by nut
Locking arm is fixed on tie down screw.
Corrosion will not be produced between locking arm and plastics skewback, also due to being designed with plastics between tie down screw and well lid
Set avoids intermetallic electrochemical rust, so as to ensure that mechanism's reliability of operation.
Finally it is pointed out that above example is merely to illustrate the technical solution of the utility model and indefiniteness skill
Art scheme.It will be understood by those within the art that, those are modified to the technical solution of the utility model or wait
With replacing without deviating from the technical program objective and the content of scope, all should cover in right of the present utility model
In.
