Abstract
The utility model provides a novel ball-typed anti-theft nut comprising a nut body, steel balls, leak-proof steel washers and a clamping barrel. The novel ball-typed anti-theft nut is of hexagon shape. Threads are arranged on the inner surface of the novel ball-typed anti-theft nut. A screw hole is formed in the upper portion of an inner hole of the nut body and a circular hole larger than the screw hole in diameter is formed in the upper portion of the nut body. Two axial blind grooves are arranged on the side wall of the screw hole close to one end of the circular hole. The blind groove equally divides the circle of the screw hole and the cross section of the blind grooves are of arc shape, and the radical depth gradually decreases along the screw threads. The steel balls are internally arranged in the blind grooves and the leak-proof steel washers are arranged at the circular hole. The external diameter of the leak-proof steal washers is equal to the diameter of the circular hole, the internal diameter of the leak-proof steal washers is equal to the diameter of the screw hole and the thickness of the leak-proof steal washers is equal to the height of the circular hole. The contact surface of the circular hole and the leak-proof steal washer is welded together. The clamping barrel with the same diameter as the screw hold is arranged in the inner hole of the nut body. The novel ball-typed anti-theft nut can be easily mounted by using ordinary spanners and the nut cannot be reversed after mounted. The anti-theft effect is good and the welded steel washers can prevent the steal balls from getting out in the transportation process and the torque resistance of the nut is increased.
Description
Technical field
The utility model relates to a kind of anti-theft nut, relates in particular to a kind of new pattern rolling ball formula anti-theft nut.
Background technique
The nut that is used for playing the role of fastening is widely used, be seen everywhere, but plain nut is installed, dismounting is all easy than the appearance of a school, so some special places: the fixed installation of open-air all kinds of power equipments, machinery is if fix with plain nut, be easy to be destroyed by the lawless person, though some anti-theft nuts are also arranged now, but because of structure reason itself, need be with supporting spanner during installation, retaining leakage packing ring comes off easily in transit, and globule antitheft, fixation is disappeared into thin air, and causes whole anti-theft nut to cancel, can't use, cause the wasting of resources.
Given this, be necessary to provide a kind of new pattern rolling ball formula anti-theft nut to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of new pattern rolling ball formula anti-theft nut, and it is simple in structure, and is easy to operate, can have the suburb to prevent dismounting, plays antitheft effect, is convenient to transportation.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of new pattern rolling ball formula anti-theft nut, comprise nut body, steel ball, leakproof Steel Washer, card bucket, described nut body profile is hexagon, nut body endoporus top is screw, the bottom is that diameter is greater than the circular hole of screwhole diameter, there is the leakproof Steel Washer at the circular hole place, have two axial blind grooves near on the screw sidewall of circular hole one end, the hexagonal profile makes nut finish installation with common wrench, needn't non-usefulness with it supporting special key install.
As the further improvement of the technical program, blind groove is divided the screw circumference equally, and radial depth turns to gradually and reduces along screw thread, is provided with steel ball in the blind groove, and after installation, nut can not backward rotation, plays antitheft effect.
Further improvement as the technical program; there is diameter the screw lower end greater than the circular hole of screwhole diameter; there is the leakproof Steel Washer at the circular hole place; described leakproof Steel Washer outer diameter is identical with Circularhole diameter; inner diameter is identical with card bucket diameter; thickness is identical with the circular hole height; and leakproof Steel Washer and circular hole contacting point weld together; in transportation process, can not break away from because of rocking more greatly with nut body; better protection steel ball; protect the integrity of anti-theft nut integral body, and increased the torque resistant power of whole nut.
Compared with prior art; the hexagonal profile of the utility model ball type anti-theft nut determine the spanner that uses can not be special, with the supporting spanner of nut; have two radial depths on the screw internal surface and turn to the axial blind groove that reduces gradually along screw thread; be provided with steel ball in the blind groove; can not reverse after finishing fixed installation; good anti-theft effect; the Steel Washer that welds together with circular hole; make the torque resistant power of nut bigger stronger; and in transit better protection steel ball, whole nut can can't not used because of the disappearance of inner body.
Description of drawings
Fig. 1 is the schematic cross-section of the utility model ball type anti-theft nut.
Fig. 2 is the generalized section at the 6-6 place of the utility model ball type anti-theft nut.
Fig. 3, Fig. 4 are the schematic representation of the utility model ball type anti-theft nut implementation process.
Embodiment
See also Fig. 1-shown in Figure 4, the utility model provides a kind of new pattern rolling ball formula anti-theft nut, comprise nut body 1, two axial blind grooves 2 of screw internal surface, two axial blind grooves 2 are divided the screw circumference equally, the built-in steel ball 3 of blind groove, and there is diameter the screw lower end greater than the circular hole of screwhole diameter, 6 is the jointing place of circular hole and blind groove, the circular hole place has outer diameter identical with Circularhole diameter, and inner diameter is identical with screwhole diameter, the leakproof Steel Washer 4 that thickness is identical with the circular hole height, 8 is that Circularhole diameter is greater than the part of screwhole diameter, the card bucket 5 that the built-in diameter of screw is identical, card bucket length is greater than the summation of circular hole and blind slot length, and when nut was installed, bolt 7 correspondences were blocked bucket 5, with common wrench rotating nut body 1, along with entering of bolt 7, card bucket 5 is ejected by bolt gradually, and steel ball 3 turns to narrow place by wide place, fixed nut, can not counter-rotation pull down.
The hexagonal profile of the utility model ball type anti-theft nut determines that the spanner that uses can not be special, supporting with nut; have two radial depths on the screw internal surface and turn to the axial blind groove that reduces gradually along screw thread; be provided with steel ball in the blind groove; can not reverse after finishing fixed installation; good anti-theft effect; the Steel Washer that welds together with circular hole; make the torque resistant power of nut bigger stronger; and in transit better protection steel ball, whole nut can can't not used because of the disappearance of inner body.
The above; it only is most preferred embodiment of the present utility model; be not that the utility model is done any pro forma restriction; any those of ordinary skill in the art; do not breaking away under the technical solutions of the utility model scope situation; utilize the method content of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, all belong to the scope of claims protection.
