Abstract

The utility model discloses a looseness-prevented riveting nut. The looseness-prevented riveting nut comprises a nut body, wherein the cross section of the nut body is T-shaped, the nut body comprises a horizontal portion and a vertical portion, a prismatic step is arranged on an end face, facing to the vertical portion, of the horizontal portion, and at least two looseness preventing teeth are arranged on each side face of the prismatic step; furthermore, the arranged looseness preventing teeth are triangular-prism-shaped, and one side faces of triangular prisms are fixedly connected with the side faces of the prismatic step. The looseness-prevented riveting nut has the advantages of good looseness preventing effect and low cost.

Description

A kind of locking riveting nut

Technical field

The utility model relates to a kind of fastening piece, especially a kind of locking riveting nut.

Background technique

Riveting nut is widely used in the fields such as mechano-electronic, but common riveting nut of the prior art is when connecting product, assembling inconvenience and anti-loosing effect are poor, thereby easily cause product to come off, other component are caused to damage, return simultaneously and produce or the staff brings potential safety hazard, cause manufacturing efficiency low, increase the problems such as maintenance expenses and engineering time.

The model utility content

In order to overcome the deficiencies in the prior art, the utility model provides the locking riveting nut that a kind of anti-loosing effect is good, cost is low.

To achieve these goals, the technical solution adopted in the utility model is: a kind of locking riveting nut, comprise nut body, described nut body cross section is T-shaped, described nut body comprises horizontal part and vertical portion, it is characterized in that: the end face of described horizontal part towards described vertical portion is provided with the prism-shaped step, and each side of described prism-shaped step all arranges at least 2 locking teeths.

As further setting of the present utility model, described locking teeth is triangular prism shaped, and a side of tri-prism is fixedly connected with the side of described prism-shaped step.

As further setting of the present utility model, the cross section of described locking teeth is isosceles triangle.

As further setting of the present utility model, the height of described isosceles triangle is 0.5~0.8mm.

As further setting of the present utility model, the locking teeth on each side of described prism-shaped step is uniformly distributed, and the distance between locking teeth and locking teeth is 2~2.5mm.

As further setting of the present utility model, the cross section of described prism-shaped step is the regular hexagon structure.

As further setting of the present utility model, the other end that the vertical portion of described nut body is connected with described horizontal part relatively is provided with the chamfering of 30 °.

Adopt such scheme, the utility model is provided with the prism-shaped step between the horizontal part of nut body and vertical portion, be provided with locking teeth on step surface, when riveting nut, with riveting screw, coordinate while being riveted on plate-like product, locking teeth on riveting nut is pressed in plate, can play antitorque effect, guarantee that this fastening piece and plate-like product stable connection do not rotate, thereby reach good fastening effect.And traditional riveting parts need to be when with special-shaped material, preventing that it is connected with riveting products rotation, special-shaped cost of material is high, add and easily produce surperficial bad phenomenon man-hour.The utlity model has the advantage that anti-loosing effect is good, cost is low.

Below in conjunction with accompanying drawing, the utility model is further described.

The accompanying drawing explanation

Accompanying drawing 1 is the utility model specific embodiment structural representation;

The worm's eye view that accompanying drawing 2 is the utility model accompanying drawing 1.

Embodiment

Specific embodiment of the utility model is locking riveting nut as shown in Figure 1-2, comprise nut body 1, nut body 1 cross section is T-shaped, nut body 1 comprises horizontal part 11 and vertical portion 12, towards vertical portion, 12 end face is provided with prism-shaped step 3 to horizontal part 11, each side of prism-shaped step 3 all arranges at least 2 locking teeths 4, and 2 or 3 or 4 locking teeths 4 can be set according to actual needs.Locking teeth 4 is triangular prism shaped, and a side of tri-prism is fixedly connected with the side of prism-shaped step 3, and toward the outer side, the locking teeth 4 of triangular prism shaped structure more easily is pressed into and is connected in product, can be more laborsaving at the tip of tri-prism.

The cross section of above-mentioned locking teeth 4 is isosceles triangle as shown in Figure 2, can also be right-angled triangle or equilateral triangle structure, the height of this isoceles triangle shape is 0.5~0.8mm, can be 0.6mm, 0.7mm, 0.8mm, and the height in the utility model is 0.5mm.

Locking teeth 4 on each side of above-mentioned prism-shaped step 3 is uniformly distributed, and between locking teeth 4 and locking teeth 4 the distance be 2~2.5mm, in the utility model the distance be 2mm.

The cross section of above-mentioned prism-shaped step 3 is the regular hexagon structure, and each side is equipped with 2 locking teeths 4.

The other end that the vertical portion 12 of above-mentioned nut body 1 is connected with horizontal part 11 relatively is provided with the chamfering of 30 °.

The utility model is provided with prism-shaped step 3 between the horizontal part 11 of nut body 1 and vertical portion 12, be provided with locking teeth 4 on the side of prism-shaped step 3, coordinate with riveting screw when riveting nut and be riveted on while being connected on product, locking teeth 4 on riveting nut is pressed into and is connected in product, can play antitorque effect, guarantee this fastening piece and be connected the product stable connection not rotate, thereby reach good fastening effect.And traditional riveting parts need to be when with special-shaped material, preventing that it is connected with riveting products rotation, special-shaped cost of material is high, add and easily produce surperficial bad phenomenon man-hour.The utility model is to be made by admiro, and maximum pull can reach 15000N, and maximum assembly force can reach 13000N; The utlity model has the advantage that anti-loosing effect is good, cost is low.
