Technical field

The utility model relates to a kind of nut, particularly a kind of with general instrument body cannot be unscrewed dismounting on screw, can reach the nut of safety locking effect.

Background technique

At present, general nut 10, mostly be set to hexagon, with relative two walls of tool holding in nut 10, nut 10 can be rotated on screw 11, carry out the action being spirally connected or dismantling, if and when nut 10 is wanted Permanent lock to be fixed in object 12 is not dismantled, be mostly locked in after on screw 11 by nut 10, and give spot welding 13 (referring to shown in Fig. 1) in the end face of nut 10 and screw 11 place of being spirally connected, nut 10 can be prevented to be disassembled, to reach effect of safety locking; But existing nut 10 is disassembled for preventing, be fixed on screw 11 with spot welding 13, it is spirally connected comparatively time-consuming, bothersome, and construction cost is higher.

Model utility content

For solving the problems of the technologies described above, main purpose of the present utility model, providing a kind of with general instrument body cannot be unscrewed dismounting on screw, can reach the nut of safety locking effect.

For achieving the above object, the technological scheme that the utility model adopts is: a kind of nut, be provided with body, one end face of this body is provided with connecting body, and the joint of this connecting body and this body is set to the cut through of thinner thickness, and the other end of this connecting body is provided with cramping body, this cramping body is set to hexagon, in this body, be provided with inner bolt hole, and be provided with perforation in this cramping body, this perforation is connected with this inner bolt hole.

Wherein, the outer wall of this body is set to smooth cylndrical surface.

Wherein, the outer wall of this body is set to smooth conical surface.

Compared with prior art, the utility model has the advantage of of technique scheme is adopted: nut can facilitate screw lock on screw, can prevent from unscrewing dismounting after locking, can reach safety locking effect of Anti-dismantling.

Embodiment

About the utility model is for reaching above-mentioned application target and effect, the technological means adopted, now list preferably feasible case study on implementation, and coordinate shown in accompanying drawing, details are as follows:

First embodiment of the present utility model, refer to shown in Fig. 2,3, its nut 2 is mainly provided with a body 20, the outer wall of this body 20 is set to smooth cylndrical surface 21, one end face of this body 20 is provided with connecting body 22, this connecting body 22 and the joint of this body 20 are set to the cut through 23 of thinner thickness, a cramping body 24 is provided with in the another end face of this connecting body 22, this cramping body 24 is set to hexagon, in this body 20, be provided with inner bolt hole 25, and be provided with perforation 26 in this cramping body 24, this perforation 26 is connected with this inner bolt hole 25, so, a nut structure is.

During use, refer to Fig. 4, shown in 5, first screw 3 is arranged on the object 4 for locking, one end of its screw 3 convexedly stretches in the side wall surface of object 4, again by nut 2 with tool holding on cramping body 24, nut 2 is driven to rotate on screw 3, nut 2 screw locks are on screw 3, the side wall surface of the body 20 of nut 2 is made to fit tightly on the side wall surface of object 4, its body 2 cannot rotation displacement again by location, again cramping body 24 is clamped and continue to rotate, the connecting body 22 of its nut 2 is connected to the cut through 23 of body 2, because of the thinner thickness at this place, so warping force when relying on cramping body 24 to rotate, connecting body 22 can be blocked in cut through 23, connecting body 22 and cramping body 24 are separated with body 20 (referring to shown in Fig. 5), connecting body 22 and cramping body 24 are taken off on screw 3, body 20 is only stayed to be locked on screw 3, and the outer wall of body 20 is because being set to smooth cylndrical surface 21, so also body 20 cannot be unscrewed dismounting on screw 3 with general instrument, effect of safety locking can be reached, need not more separately with spot welding solid welding, can greatly save engineering time and cost.

Second embodiment of the present utility model, refer to Fig. 6, shown in 7, its nut 2 is mainly provided with a body 20, the outer wall of this body 20 is set to the smooth conical surface 27 of ecto-entad gradually-reducing shape, one end face of this body 20 is provided with connecting body 22, this connecting body 22 and the joint of this body 20 are set to the cut through 23 of thinner thickness, a cramping body 24 is provided with in the another end face of this connecting body 22, this cramping body 24 is set to hexagon, inner bolt hole 25 is provided with in this body 20, and in this cramping body 24, be provided with perforation 26, this perforation 26 is connected with this inner bolt hole 25, so, be a nut structure.
