Put.
Background technology
Steering wheel control surface locking mechanism is using fluting button-headed screw fastening means.When the screw assembles, in threaded portion, spiral shell
Ailhead lower surface scribbles larger amount of epoxide-resin glue, to the locking and sealing at screw.In repaired item, it is necessary to decompose
With the control surface locking mechanism of assembling steering wheel, this just needs to pull down fluting button-headed screw.Torn open using general bottle opener (screwdriver)
, it is necessary to screw while apply certain axial force and moment of torsion when unloading screw, in dismounting steering wheel control surface locking mechanism fixing screws
When, due to the limitation in " anti-removal force " powerful caused by epoxy resin cure and screw disassembling space, screw can not be loaded
Suitable axial force ensures the reliable contacts of bottle opener and screw notch, so be difficult to loading dismantle needed for moment of torsion.Using general
Instrument dismantles the screw by force, will cause the destruction of screw head, causes screw can not continue to dismantle.How can not damaged and
Easy easily dismounting fluting button-headed screw turns into insoluble technical barrier for a long time.
In view of the foregoing, a kind of provision for disengagement for steering wheel control surface locking mechanism screw is now developed.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided one kind is used for steering wheel rudder face locking machine
The provision for disengagement of structure screw, it is ensured that bottle opener blade and fluting button-headed screw head " flat recess " are abundant during whole disassemble
Contact, reliable delivery removal torque, safety, the purpose of nondestructive demounting are realized, and can improves operating efficiency, solves product and repaired
Bay section can not disassemble problem caused by screw disassembles damage in journey.It ensure that screwdriver head and spiral shell during spanner transmits moment of torsion
Nail groove portion relative position is constant, moment of torsion can effectively apply, and realizes safely, quickly, reliably dismantling to screw.
The utility model to achieve these goals, adopts the following technical scheme that：One kind is used for steering wheel control surface locking mechanism
The provision for disengagement of screw, be by：Centring ring, flange, cross bar, nose portion, projection, housing screw, supporting table, sliding sleeve, bottle opener,
Bolt, nut are formed；Horizontal cross bar is set below the centring ring of circular arc, centring ring periphery sets flange, centring ring periphery with
Steering wheel control surface locking mechanism termination insert district is formed between flange, the nose portion of the both ends protrusion centring ring of cross bar is set inwardly
Projection, for projection perpendicular to nose portion, two projections are located at the inner side of cross bar, housing screw and the screwed hole reserved on projection
Corresponding to be spirally connected, the middle part of the inside of cross bar sets raised supporting table, and hole, sliding sleeve periphery lower section are threaded in the middle part of supporting table
External screw thread is set, be hexahedron structure above sliding sleeve, the external screw thread of sliding sleeve is corresponding with the bolt apertures of supporting table to be spirally connected, on sliding sleeve is interior
Side sets the epicoele of cylinder, and lower section sets cavity of resorption, and epicoele inner surface setting internal thread, the top of bottle opener is arranged at through cavity of resorption
Upper intracavitary, nut is set on bolt, bolt bottom is corresponding with the internal thread of epicoele to be spirally connected, and bolt lower surface connects with bottle opener upper surface
Touch.
The length of the peak of the centring ring and the vertical line at cross bar center is more than the radius of centring ring inner periphery.
The diameter of the epicoele is more than the width of cavity of resorption.
The cavity of resorption is cuboid cavity, more than the cutter head of bottle opener is tetrahedral structure, the outer surface of bottle opener and lower intracavitary
Surface profiles.
The beneficial effects of the utility model are：In use, first by outside the termination insertion centring ring of steering wheel control surface locking mechanism
In steering wheel control surface locking mechanism termination insert district between week and flange, the fluting cup head on bottle opener lower end insertion steering wheel rudder face
Screw, the present apparatus is set to be fixed on the end of steering wheel control surface locking mechanism by housing screw, regulating bolt makes bolt bottom surface to rising
Sub- upper end compresses, and bolt lower surface compresses the upper surface of bottle opener, plays positioning, limitation bottle opener acts on along sliding sleeve axial movement；When
After bolt presses bottle opener, tighten nut and be in close contact with sliding sleeve upper surface, play locking bolt effect, bottle opener lower end is to steering wheel rudder
Fluting button-headed screw on the locking mechanism of face is compressed, and the position of bolt is locked by the nut on bolt, makes bottle opener
It is connected as a single entity with sliding sleeve, using the hexahedron part on spanner clamping sliding sleeve top, the high pulling torque that spanner applies is driven under sliding sleeve
Portion supporting table screwed hole internal rotation, sliding sleeve drive bottle opener rotation cross-notching button-headed screw dismantled, bottle opener with it is required
The fluting button-headed screw of dismounting is moved up (pitch is identical) with identical speed, it is ensured that bottle opener blade and fluting button-headed screw
Head " flat recess " fully contacts during whole disassemble, and reliable delivery removal torque, realizes safety, the mesh of nondestructive demounting
, and can improve operating efficiency, solve product repair procedures in because screw disassemble damage caused by bay section can not disassemble problem.Protect
Demonstrate,prove that screwdriver head and screw groove portion relative position during spanner transmits moment of torsion be constant, moment of torsion can effectively apply, realized
To safely, quickly, reliably dismantling for screw.
Bolt limits the axial location of bottle opener, and nut realizes the limit self to bolt, and the endoporus of sliding sleeve is by four directions and spiral shell
Line two parts are formed, and four directions is used for the transmission moment of torsion that is connected with bottle opener, and screw thread is cylindrical to bolt connection and limiting axial location
It is threaded, to cooperatively form screw with supporter；Bottle opener by changing a social system general screwdriver bit or self-control, in shank plus
Work four directions, to transmit moment of torsion；Supporter coordinates to be connected with bay section with sliding sleeve, sliding sleeve is formed screw.
The utility model guarantees cross-notching button-headed screw and applies enough removal torques, while does not destroy fluting semicircle
The head of head screw.During design, the externally threaded pitch p sliding sleeves of sliding sleeve should be identical with fluting button-headed screw pitch p screws, to protect
When screw is changed into axial linear movement by card sliding sleeve, the climb h sliding sleeves of sliding sleeve should be with button-headed screw h spiral shells of slotting
Follow closely identical, to avoid sliding sleeve from being moved with button-headed screw of slotting interference.
It is the utility model safe operation, convenient, fast, can nondestructive demounting fluting button-headed screw, ensure that work well
Make security, reliability, meet requirement.
