The utility model is characterized in that the rivet comprises a rivet body and a rivet rod, and one end of the rivet body is in umbrella shape structure. The umbrella rivet has the advantages of simple structure, convenient operation, firmness and durability, and is suitable for the fastening field, such as architectural decoration, mechanical manufacture, etc.

Description

Umbrella rivet

The utility model relates to a kind of rivet, particularly relates to a kind of Umbrella rivet.

In the connection of steel construction piece, also often use the method that riveting connects.

When carrying out the riveting connection, at first on riveted parts, hole, after the riveted parts boring, often cause overlap and small embossment part easily around the nail aperture, in addition, the shade bottom surface of the rivet head that the connection of riveting at present is used great majority again is plane shape, be in this case, riveting connect will occur owing riveting or rivet head around with riveted parts not closely connected phenomenon repeatedly, this will influence riveting intensity, reduces riveting quality.If eliminate this defective, must after riveted parts boring, repair processing again, so, not only increased operational sequence, and, working efficiency also reduced.

The purpose of this utility model is that a kind of improved Umbrella rivet will be provided, after it can overcome riveted parts boring effectively, and the caused phenomenon that influences riveting quality in rivet aperture.

The purpose of this utility model is achieved in that Umbrella rivet has rivet bar and rivet body.

The head of described rivet body is to be the umbrella shape shape.

Because the head design of the rivet body of Umbrella rivet of the present utility model becomes the umbrella shape shape, therefore, it is simple and reasonable for structure, the overlap in nail aperture and the problem of small embossment part have been solved, and the operational sequence of riveted joint has also obtained minimizing, working efficiency improves greatly, simultaneously, has also saved a large amount of metallic material.

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

Fig. 1 is the structural representation of Umbrella rivet of the present utility model.

Fig. 2 is the schematic representation of the rivet body of Umbrella rivet of the present utility model.

Fig. 3 is the schematic representation of the rivet bar of Umbrella rivet of the present utility model.

Fig. 4 is the working state figure of Umbrella rivet of the present utility model.

Describe details and working condition in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4 according to the Umbrella rivet that the utility model proposes.

Umbrella rivet 1 comprises rivet bar 3 and rivet body 2.

Rivet bar 3 is metallic rod of a garden cylindricality, and an impression is arranged at its top is point of rupture, and an edge part is arranged around the end, upper end.

Rivet body 2 is to be the garden post shapes, and the head 4 of an end of the rivet body 2 of garden post shapes is the umbrella shape shape, and a garden cylindricality blind hole is arranged in the body of the rivet body 2 of garden post shapes, and blind hole matches with the upper end portion of rivet bar 3.The rivet body 2 of garden cylindricality is the upper end portion that is sleeved on rivet bar 3, forms a fixed connection.

The rivet body 2 of Umbrella rivet 1 and rivet bar 3 are made by Stainless Acid Resistant Steel.Corrosion with opposing atmosphere and chemical erosion medium.

During the riveting attended operation, according to the diameter of Umbrella rivet 1, the bore diameter that selection adapts is holed on riveted parts 5,6 earlier.The hole of being bored must be vertical with riveted parts 5,6.Then, Umbrella rivet 1 is put into the hole of riveted parts 5,6, last, the underpart of rivet bar 3 is inserted in the hand riveter muzzle, under the staking effect, the rivet body 2 of rivet 1 expands gradually, is broken until rivet bar 3, and riveted parts 5,6 promptly fuses.

Claims (2)

1, a kind of Umbrella rivet 1, it is made up of rivet body 2 and rivet bar 3, it is characterized in that a termination portion 4 of above-mentioned rivet body 2 is the umbrella shape shape.

2, rivet according to claim 1 is characterized in that above-mentioned rivet body 2 adopts Stainless Acid Resistant Steel to make.
