Description

Locking external member theft-prevention structure

Technical field

The utility model relates to a kind of locking external member theft-prevention structure, is meant that especially stressed member in this locking external member has peripheral protective frame and prevents that this stressed member from allowing the robber rotate unlatching easily because of knocking to be out of shape.

Background technique

The car-wheel frame need be fixed in and just can make this take turns frame on the wheel shaft of automobile and wheel shaft rotates synchronously, and the wheel frame has a plurality of screws and wheel shaft is provided with double-screw bolt or screw (deciding according to production specification), and according to the double-screw bolt on the wheel shaft or screw selects to use nut or bolt to pass this screw of taking turns frame and this wheel shaft is fixed, make wheel frame and the wheel shaft can be in conjunction with fixing, general bolt and nut will be in the various profiles of its end periphery design except the thickness specification, as Fig. 1-1 and (the three-dimensional legend one of known locking external member shown in Fig. 1-2, two), general wheel frame fixed sleeve part comprises force-applying piece 2 and stressed member 1, this force-applying piece 2 is divided into force side 21 and connecting end 22, this stressed member 1 is divided into force side 11 and locking end 12, the locking of this stressed member 1 hold 12 extensible formation to have the bolt 121 of outside thread 122 or form have internal thread 124 tubular spaces 123 nut to cooperate the vehicle wheel shaft specification, the force side 11 of this stressed member 1 also can be designed to have the column or the groove shape of antitheft cutting slot 111 respectively, and connecting end 22 palpuses of this force-applying piece 2 antitheft cutting slot 111 complete and this force side 11 coincide and just can rotate stressed member 1 application of force, therefore general purpose tool can't rotate this stressed member 1, prevents that the robber from dismantling car body easily; Yet, the robber still has special instrument and can utilize the force side 11 of knocking this stressed member 1 now, destroy this antitheft cutting slot 111 and force the force side 11 of this stressed member 1 to be deformed into to cooperate this special tool(s) (but promptly knock force side 11 to cause this special tool(s) be application of force rotary state) to rotate by forcing, above-mentioned known stressed member 1 is difficult to take precautions against the means of utilizing special tool(s) to hold concurrently and destroy and rotate to knock, therefore still has the risk that meets with robber's stealing.

The model utility content

Because above-mentioned known product can't be taken precautions against the opening ways that robber's special tool(s) is held concurrently and destroyed this stressed member to knock; therefore main purpose of the present utility model is to provide a kind of protection structure to suffer external force to knock distortion to take precautions against this stressed member, has this stressed member body of protection concurrently and not rotated by improper external force.

The utility model is a kind of locking external member theft-prevention structure; the wheel frame and the wheel shaft of vehicle are used to lock; this locking external member theft-prevention structure is divided into force-applying piece and stressed member; this stressed member can be bolt or nut according to vehicle design specification difference; and this force-applying piece is to fasten with this stressed member; and this force-applying piece can be connected with instruments such as spanner or socket wrenchs; being convenient to this stressed member application of force locked, this takes turns frame and vehicle wheel shaft; this force-applying piece is divided into force side and connecting end; this stressed member is divided into force side and locking end; this force side is provided with at least one antitheft cutting slot; and this connecting end is connected with this antitheft cutting slot is identical; and this force-applying piece can apply external force by this force side and rotate this stressed member after the antitheft cutting slot of this connecting end and this is connected; the force side of this stressed member is provided with restraining groove in addition; also be provided with protective frame; embed in this restraining groove and can be in this restraining groove be that rotate in the axle center with this force side; this protective frame extends this force side lateral margin to this force side direction in addition, is not subjected to outside destroy to protect this force side.

In sum, locking external member theft-prevention structure of the present utility model can prevent that stressed member from allowing the robber rotate unlatching easily because of knocking distortion.
