Abstract
Aiming at the defects of the existing theftproof nut that threads in the nut are damaged during manufacture, so that the fixing performance is poor; the processing is tedious, so that the manufacturing cost of the nut is increased; and a theftproof jacket is easy to fall off, so that the theftproof function is poor, and the like, the utility model discloses a theftproof nut, which comprises a nut body, a cone frustum is arranged on the upper part of the nut body, a cylinder is arranged on the lower part of the nut body, and the cylinder is internally provided with threads; a theftproof jacket is sleeved outside the cylinder, the position vertical to the axial direction of the cylinder is provided with a hole, and a marble and a spring are arranged in the hole; and an annular groove is arranged outside the cylinder, and an annular convex step is arranged on the inner wall of the theftproof jacket sleeved outside the cylinder.
Description
Technical field
The utility model relates to a kind of improved anti-theft nut, can extensively use at field fixed components such as electric power system, expressway, communication system, parts.
Background technique
The safety barriers that the telecommunication cable that the electric power pylon that electric power system is built, communication system are fixed, expressway are fixed etc. all use nut.In order to improve the Safety performance of using the nut facility, avoid theft, often to use anti-theft nut.Known anti-theft nut is of a great variety, but all has certain defective.It as the patent No. 200720090142.7 anti-theft nut, it includes nut body, nut body top is circular cone, the nut body bottom is a cylindrical body, and screw thread is arranged in the cylindrical body, it is characterized in that being provided with arc groove at the screw thread place of nut along hand of spiral, be placed with hoodle, spring in the groove, fixed stop, this makes the screw thread in the nut be subjected to a lot of losses, it is poor to produce nut self fixed performance; At the groove of nut inner hole processing belt radian, the processing technology trouble, manufacturing efficiency is low; Fixed stop in groove, operation inconvenience, time-consuming, increase the nut manufacture cost; Be sleeved on the outer stealingproof sleeve of nut cylinder and come off easily, antitheft effect is poor.
Summary of the invention
At the screw thread place of nut arc groove is set during the manufacturing that exists at existing anti-theft nut, is placed with hoodle, spring in the groove, fixed stop causes the screw thread in the nut impaired, and nut self fixed performance is poor; At the groove of nut inner hole processing belt radian, the processing trouble, manufacturing efficiency is low; Fixed stop in groove, operation inconvenience, time-consuming, increase the nut manufacture cost; Being sleeved on nut cylinder other places stealingproof sleeve comes off easily, do not have defectives such as antitheft effect, the utility model discloses a kind of anti-theft nut, this anti-theft nut is not provided with arc groove at the screw thread place of nut when making, reduce the thread damage in the nut, it is poor to improve the nut fixed performance; At the groove of nut inner hole processing belt radian, processing technology is not simple, the manufacturing efficiency height; Be sleeved on the outer stealingproof sleeve of nut cylinder and be provided with anti-knocking over, avoid anti-stealing to come off, strengthen the antitheft effect of anti-theft nut.
Taked following technological scheme for realizing the purpose of this utility model:
Make a kind of anti-theft nut, this anti-theft nut includes nut body, and nut body top is circular cone, and the nut body bottom is a cylindrical body, and screw thread is arranged in the cylindrical body; Be set with stealingproof sleeve in cylindrical outside, it is characterized in that hoodle and spring being installed in the hole being axially arranged with the hole perpendicular to cylindrical; Be provided with annular recess in cylindrical outside, the stealingproof sleeve inwall that is sleeved on the cylindrical body outside is provided with ring-type and protrudes step.
Characteristics of the present utility model are simple in structure, and are easy to manufacture, reduce the manufacture cost of anti-theft nut; Its remarkable advantage is the screw thread loss that reduces anti-theft nut, improves the quality of anti-theft nut; Be used at the annular recess of nut body outside and the protrusion step of stealingproof sleeve, improve the theftproof performance of anti-theft nut.
Description of drawings
Further describe technical characteristics of the present utility model below in conjunction with accompanying drawing:
Fig. 1, an embodiment's of the utility model sectional structure schematic representation;
The A--A sectional structure schematic representation of Fig. 2, embodiment Fig. 1.
Among the figure: 1, stealingproof sleeve 2, spring 3, hoodle 4, nut body 5, hole 6, annular recess 7, screw thread 8, protrusion step
Embodiment
As shown in Figure 1 and Figure 2,4 among the figure is nut bodies, and the top of nut body 4 is circular cone, and the bottom of nut body 4 is cylindrical bodys, and screw thread 7 is arranged in cylindrical body; Be set with stealingproof sleeve 1 in the cylindrical body of nut 4 outside, it is characterized in that being axially arranged with hole 5 perpendicular to cylindrical hoodle 3 and spring 2 being installed in the hole 5, hoodle and spring 2 after being installed in the hole 5 are blocked mouth, and hoodle 2 and spring 3 are deviate from; Be provided with annular recess 6 in cylindrical outside, the inwall that is sleeved on cylindrical body outside stealingproof sleeve 1 is provided with ring-type and protrudes step 8; This circular step 8 is after the tubular stealingproof sleeve is sleeved on cylindrical body, the circular step that extruding forms.
Because to punching, so the damage of the screw thread 7 in the cylindrical body is few, has strengthened intensity of the present utility model perpendicular to cylinder axis for the utility model; The stealingproof sleeve 1 that is sleeved on the cylindrical body outside has protrusion step 8, and this protrusion step 8 can enter in the cylindrical annular slot 6, prevents that effectively stealingproof sleeve 1 from coming off, and strengthened theftproof performance of the present utility model.
