Description
Technical field
The utility model belongs to rivet joint screw technical field, especially a kind of rivet joint screw for preventing from loosening.
Background technology
Existing rivet joint screw, generally includes head and columnar part, there is skewed slot together between head and columnar part.Pass through pressure
Rivet joint screw is pressed into the riveted holes of thin-slab structure by power machine, and the periphery of riveted holes generates plastic deformation, and deformed part is squeezed into
In skewed slot so that rivet joint screw is riveted tightly on backboard.Existing rivet joint screw is connect with backboard, once sending out in transport or carrying
Raw collision, will loosen, the attachment force of rivet joint screw and backboard can be caused not reach requirement, and in process of production, riveting has riveting
Connecing the backboard of stud not up to can lead to scrapping for entire backboard.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art, providing one kind can prevent from loosening
Rivet joint screw, the utility model product passes through flower for being riveted on the backboard of television set so that television set is connected to wall hanging frame
The double locking of tooth and anti-rotation slot and prevent rotation from designing, easy for installation, fastening effect is good, and attachment force is strong, reduces production damage
Consumption, it is cost-effective, help to improve the productivity effect of enterprise.
In order to solve the above technical problems, the utility model provides a kind of rivet joint screw for preventing from loosening, rivet joint screw
The stud lower part on stud top and cylinder type including cylinder type, along the circumferential direction sets between stud top and stud lower part
There is colored tooth, spends the junction on tooth and stud top to be along the circumferential direction equipped with annular groove, stud lower part is centrosymmetric equipped with wedge shape
Anti-rotation slot；
The inside on stud top is equipped with threaded hole centered on central shaft, and threaded hole extends to stud lower interior portion, spiral shell
The upper end on column top is open, and the lower end of stud lower part is provided with water falling hole.
The technical solution that the utility model further limits is：
The diameter on aforementioned stud top is less than the diameter of stud lower part.
The diameter of aforementioned colored tooth is between stud top and stud lower part.
The diameter of aforementioned annular groove is less than the diameter on stud top.
Smaller one end of the anti-rotation slot of aforementioned wedge extends to colored tooth, and larger one end reaches the outer end of stud lower part.
The utility model has the beneficial effects that：
The rivet joint screw of the utility model design includes stud top and stud lower part, and the two intersection is equipped with cricoid flower
Tooth, the junction on flower tooth and stud top are equipped with annular groove, and stud lower part outer wall is provided with 3 anti-rotation slots, stud lower part it is outer
End is equipped with water falling hole, convenient after cleaning product, will not ponding, prevent screw thread from getting rusty, extend the screw thread service life.Riveting after riveting
It connects and forms gear-like between stud and backboard, while thering are 3 anti-rotation slots to block material so that rivet joint screw is fixed very
Hardly possible loosens.The utility model product for being riveted on the backboard of television set so that television set is connected to wall hanging frame, by flower tooth and
The double locking of anti-rotation slot designs, and easy for installation, fastening effect is good, and attachment force is strong, reduces production loss, cost-effective, has
Help improve the productivity effect of enterprise.

Specific implementation mode
Embodiment 1
The present embodiment provides a kind of rivet joint screws for preventing from loosening, as shown in Figure 1 and Figure 2, a kind of riveting for preventing from loosening
Connect stud, rivet joint screw includes the stud top 1 of cylinder type and the stud lower part 5 of cylinder type, under stud top 1 and stud
Flower tooth 4 is along the circumferential direction equipped between portion 5, flower tooth 4 and the junction on stud top 1 are along the circumferential direction equipped with annular groove 3, stud
Lower part 5 is centrosymmetric equipped with wedge-shaped anti-rotation slot 6；As shown in Figure 3, Figure 4, during the inside on stud top 1 is with central shaft
The heart is equipped with threaded hole 2, and threaded hole 2 extends to inside stud lower part 5, the upper end opening on stud top 1, under stud lower part 5
End is provided with water falling hole 7.
The diameter on aforementioned stud top 1 is less than the diameter of stud lower part 5.The diameter of aforementioned colored tooth 4 is between 1 He of stud top
Between stud lower part 5.The diameter of aforementioned annular groove 3 is less than the diameter on stud top 1.The anti-rotation slot 6 of aforementioned wedge it is smaller
One end extends to colored tooth 4, and larger one end reaches the outer end of stud lower part 5.
The rivet joint screw of the present embodiment design includes stud top and stud lower part, and the two intersection is equipped with cricoid flower
Tooth, the junction on flower tooth and stud top are equipped with annular groove, and stud lower part outer wall is provided with 3 anti-rotation slots, stud lower part it is outer
