The protection assembly for the automobile wheel nut solves problems that a protection cover cannot be easily pulled out from an external nut due to a boss snapped onto a chamfer, so that dismounting work is inconvenient. The protection assembly for the automobile wheel nut comprises a cylindrical cover body; the cover body is provided with a cavity and an open peripheral wall is tightly matched with a side surface of the wheel nut; the cavity bottom is provided with an avoiding groove accommodating an end part of a bolt; and the external part of the cover body is provided with connecting grooves capable of being conveniently detached. The protection assembly for automobile wheel nut can be detached as long as a specialized detaching tool is snapped into the connecting grooves, thereby providing convenient detachment; and the protection assembly has a function of anti-theft to some extent.
Description
Technical field
The utility model belongs to the automobile tire technical field, relates to a kind of protection assembly of protection assembly, particularly Car Wheel Nut.
Background technique
Because the working environment of wheel is extremely severe, the connected screw rod of wheel nut suffers erosion for a long time, the corrosion dead phenomenon of even becoming rusty very easily occurs.When vehicle casts anchor while needing removing vehicle tyres, can make unloading process become very difficult; Simultaneously, the damage of connecting thread also can cause join strength to reduce, and allows to shorten the working life of component.In the case, all kinds of wheel nut assemblies that increase safety cover outside wheel nut arise at the historic moment.Wheel, as the part that runs up, not only requires no-float between wheel nut and safety cover, the unlikely loss that comes off of safety cover in the Vehicle Driving Cycle process; Secondly, also require vehicle to cast anchor while needing removing vehicle tyres, wheel nut and safety cover are easy to dismounting.
Due to the nut bore indent on wheel (aluminium alloy wheel rim); existing all kinds of wheel nut assembly; the nut safety cover can't meet requirement for convenience detach; as needed, dismantle; instrument will act directly on nut safety cover side; easily cause nut safety cover distortion, can cause in the course of time the nut safety cover loss that comes off.The patent [application number: 91212544.6] of a kind of tyre nut protective cover for car of announcing as Patent Office of the People's Republic of China, be comprised of cover body and cover cap, boss and opening elastic groove can be set, in order to prevent from dropping on the chamfering that is stuck in outer nut on cover body.On cover cap, attachment hole can be set, link together by fastening piece and inner nut.The utility model can protect effectively to the automotive tyre nut outside existing being exposed to, and makes its screw thread and binding site thereof avoid the erosion of sandstone and muddy water.But the safety cover of this structure, because boss is stuck on chamfering, is difficult to it is pulled up from outer nut, causes dismounting inconvenient, can only rely on external force to destroy by force safety cover.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of protection assembly of easy-to-dismount Car Wheel Nut.
The purpose of this utility model can realize by following technical proposal: a kind of protection assembly of Car Wheel Nut; it is characterized in that; this protection assembly comprises tubular cover body; cover body has the opening perisporium and wheel nut side phase close-fitting of inner chamber and inner chamber; described intracavity bottom also has the groove of dodging that can hold the bolt end, and described cover body lateral part has easy-to-dismount connecting groove.
The side interference fit of the internal chamber wall of cover body and wheel nut, can guarantee the pull-out force requirement of 50Nm left and right; The intracavity bottom of cover body is the groove of dodging with certain space, when bolt stretches out an end through after wheel nut, dodges groove and can hold this end, both can protect the wheel bolt end not by corrosion, guarantees that again cover body does not produce and interferes with bolt.Near end position, connecting groove is set at the cover body outer side surface, the special-purpose extracting tool of convenient employing is dismantled, and secondly also has certain anti-theft function.
In the protection assembly of above-mentioned Car Wheel Nut, the inner chamber perisporium of described cover body is provided with some bar shaped stiffening ribs.The cover body inner side surface is provided with stiffening rib, and stiffening rib improves the interference fit dynamics of cover body and wheel nut side, prevents from protecting assembly to come off.
In the protection assembly of above-mentioned Car Wheel Nut, described connecting groove can be circumscribed with extracting tool.During dismounting, adopt special-purpose extracting tool, snap in the connecting groove of cover body side, cover body is pulled out gently along the wheel nut axial direction, cover body is separated with wheel nut, reach the purpose of dismounting.
In the protection assembly of above-mentioned Car Wheel Nut, described extracting tool takes the shape of the letter U and two ends are provided with to projecting inward and can embed the Ka Jiao in connecting groove.The extracting tool of U-shaped has symmetrical Ka Jiao, will block in the Snap joint groove of angle, makes the locking mutually on the axial direction of wheel nut of extracting tool and cover body.
In the protection assembly of above-mentioned Car Wheel Nut, described connecting groove is opened in the cover body outside ringwise.No matter what angle of extracting tool inserts, can be embedded in connecting groove, convenient disassembly, do not need to align in advance.
As another kind of scheme, in the protection assembly of above-mentioned Car Wheel Nut, described connecting groove has several and circumferentially is distributed in the cover body outside, and quantity is corresponding one by one with the card angle quantity of extracting tool.Ka Jiao is corresponding one by one with connecting groove, makes the circumferentially upper locking of extracting tool and cover body, can drive cover body and rotate, and the situation while being bonded together for a long time for cover body and wheel nut, can first rotate cover body and make that both are loosening outwards extracts again, the raising removal efficiency.
In the protection assembly of above-mentioned Car Wheel Nut, the wall thickness of described cover body is 1cm～2cm.Because the nut bore indent on aluminium alloy wheel rim is less, the cover body of 1cm～2cm wall thickness does not take up room.
In the protection assembly of above-mentioned Car Wheel Nut, described cover body adopts nylon material to make.Sound construction, do not allow to be subject to external environment and corrode.
Compared with prior art, the protection assembly of this Car Wheel Nut is simple in structure, has higher antiseptic property, with low cost, and cover body and wheel nut interference fit, be not easy to come off, and has certain anti-theft function; During dismounting, need special-purpose extracting tool Snap joint groove to get final product, convenient disassembly.
