Abstract
The utility model relates to a theft-proof nut lock which is mainly composed of a theft-proof sleeve, a nut, a lock core, a lock sleeve and an inserting block, wherein, the nut, the lock core, the lock sleeve and the inserting block are arranged in the theft-proof sleeve. A positioning ball is arranged between the nut and the theft-proof sleeve to prevent the theft-proof sleeve from dropping off. The theft-proof sleeve can rotate. The tail end of the lock sleeve corresponding to the nut is respectively provided with grooves. The inserting block can slide in a slideway formed by grooves, and can slide into a groove arranged on the inner wall of the theft-proof sleeve. The utility model can cause the nut to keep original requirements and to have theft-proof function, having the advantages of simple structure, convenient operation and low cost.
Description
The utility model relates to theftproof lock, in particular for the theftproof lock on the automobile.
At present, nut kind and model are all very various, and it is general to have many uses too.But some article fixedly is the purpose that does not reach safety with nut only.For example, the back spare tyre that jeep is standby, stolen often, cause very big economic loss.Thereby, just force the personnel of driving of department must not be no longer to reinforce or spare tyre is positioned in the car with chain lock, like this, the usable floor area in the car is reduced, make jeep car increase unnecessary noise virtually and destroyed the original moulding of jeep.So bring inconvenience to the user.
The purpose of this utility model is to provide a kind of anti-theft nut easy to use, simple in structure, also can be antitheft to lock to overcome above-mentioned defective.
The utility model is achieved in that anti-theft nut lock is made up of stealingproof sleeve, nut, lock core, lock tube and inserted block, vertically is provided with nut along it in stealingproof sleeve.Have the groove of at least three certain circumference angles of being separated by at the stealingproof sleeve inwall, this groove is relative with the circumferential groove of opening on nut outer wall.At least three place kick place among described circumferential groove and the described groove preventing and come off between stealingproof sleeve and the nut.Lock core and the lock tube that is enclosed within on the lock core place stealingproof sleeve, and the two ends that nut is relative with lock tube all have opposed groove, and their constitute rectangle slideway, and one is that the inserted block that is slidingly connected is inserted in the described slideway and also can be moved along slideway with lock core.The inwall place of stealingproof sleeve also has a groove, and an end of inserted block can slip in this groove.Stealingproof sleeve can rotate with respect to nut and lock tube.
Its advantage of the utility model is: owing to add the function of lockmaking at nut, and not only make nut keep original screw thread to fix needs, and and make it have antitheft effect.Be used in when fixing the back spare tyre on the automobile and can guarantee the original moulding of automobile, good anti-theft effect effectively and reduce unnecessary economic loss.And simple in structure, easy to use, cost is low.

Below in conjunction with accompanying drawing the utility model is explained in detail:
Anti-theft nut lock of the present utility model as shown in Figure 1, 2, comprises a stealingproof sleeve 1, vertically is provided with nut 2 along it in the stealingproof sleeve 1.The stealingproof sleeve inwall has three with equal circumference angle (promptly being separated by 120 °) grooves distributed, and a circumferential groove of opening on this groove and the nut outer wall is relative.Three place kick and placing among described groove and the circumferential groove come off between stealingproof sleeve and the nut preventing.Lock core 4 and cover lock tube 5 thereon place stealingproof sleeve 1, and the nut tail end is relative with the lock tube tail end, and relative tail end respectively has opposed groove 7,8, their formation rectangle slideways.Insert in the described slideway with lock core 4 for the inserted block 6 that is slidingly connected and can move for one along slideway.The inwall place of stealingproof sleeve 1 also has a groove 9, and an end of inserted block 6 can slip among this groove 9.Stealingproof sleeve 1 can rotate with respect to nut 2 and lock tube 5, and the principle of lock is opposite with the identical just effect of principle of general lock.Promptly when key was pinned the nut lock, its inserted block 6 broke away from groove 9, and at this moment stealingproof sleeve 1 rotates with respect to nut 2, thereby nut can not screw down.And inserted block 6 is inserted in the groove 9, then twist stealingproof sleeve, and nut can be pulled down the nut lock or be screwed in company with rotating together.
In addition, can be shaped on pin marker (scale) with stealingproof sleeve end 11, echo mutually, the user can conveniently be used fast with inserted block 6 alignment indentation 9 at the dust cover 10 of lock core end.Gone out a little difficult problem together for simultaneously non-user.
The model of anti-theft nut lock becomes with the variation of screw thread model, can be made into various models.It not only can be used on the doughnut but also can be used for various antitheft purposes.
