Abstract

The utility model discloses a nail body for a gecko-shaped draw nail, which is composed of a nail body and a nail head. The lower segment of the nail body is provided with a joggling sheet, and the nail body is rolled into a hollow cylindric shape in a stamping way by a sheet body; the upper end of the nail body is provided with a connecting part in the extending, and the other end of the connecting part is connected with a nail cap; the end edge of the nail cap is provided with a clamping joint sheet, and the clamping joint sheet is inserted in a notch arranged on the upper end edge of the nail body; in addition, the front edge of the nail body is provided with an inner screw hole and a nail head in the welding way. The utility model can effectively increase the strength of the nail head; moreover, the fabrication is simple.

Description

The nail body of gecko blind rivet

The utility model relates to a kind of nail body structure of gecko blind rivet.

Blind rivet structure commonly used, as shown in Figure 1, the owner will be bolted in a stay bolt 2 in the screw of ailhead 14 inside of a nail body 1 with its thread section 21, and this nail body 1 is one to have the cylindrical body of mesopore 12, its upper end is provided with a head of a nail 11, the hypomere of nail body 1 then is provided with several pieces warpage sheets 13, and following closely its purposes of blind rivet that body 1 and stay bolt 2 form by this mainly is to embed on the buildings such as wallboard, interlayer, as the usefulness of affixed plate body.Its using method, see also shown in Figure 2, earlier blind rivet is penetrated the perforation of plate body 3, snap into bolt head 22 in the grip slipper 43 of front end of Rivet gun 4, force the tortuous sheet 13 of nail body 1 to form warpages again holding handle 42, and with pointing the moving pull handle 41 of plate backward, stay bolt 2 being pulled back in Rivet gun 4, and be anchored on the both sides of plate body 3 respectively with the head of a nail 11, to reach the purpose of fixed plate body; Right this kind blind rivet is because the requirement of strength of its ailhead 14 is very high; Moreover because the use amount of blind rivet is very big, cause manufacturer that the intensity and the processing speed of the ailhead of blind rivet are attached great importance to, but general blind rivet structure, the intensity that blind rivet head 14 often arranged a little less than, and processed complex and the situation that expends man-hour, probing into its reason is to be structural problem, with blind rivet structure shown in Figure 3 is example, its ailhead 51 is that integrated punching forms with nail body 5, only mat a junction 52 is connected with nail body 5 therebetween, see also Fig. 3 A, when stay bolt 2 was subjected to the pulling of Rivet gun 4, this ailhead 51 only depended on joint 52 will support whole PROPEL shown in Fig. 3 B, and its tensile strength is relatively poor; In addition, after following closely body 5 exactly and making respectively with ruthenium cap 53, again with the method for welding with these two kinds of combination of elements, as shown in Figure 4, therefore expending man-hour increases cost, the defective that this is taken place in manufacturing for general blind rivet nail body.

The purpose of this utility model is to provide a kind of ailhead of reinforcement intensity that has, the nail body structure of the gecko blind rivet of simple and easy processing and reduction manufacture cost.

The purpose of model utility is to realize like this, a kind of nail body of gecko blind rivet, formed by a nail body and an ailhead, the hypomere of nail body is provided with the warpage sheet, the nail body by a lamellar body punching press after volume be set as hollow cylindrical, a junction is extended in the upper end of nail body, the other end of this joint is then received a head of a nail, establish a card knot sheet on its ora terminalis of this head of a nail, be used for the head of a nail and nail body when combining, this card knot sheet is inserted in the set breach of ora terminalis on the nail body, with above-mentioned joint formation and the head of a nail with follow closely at 2 that body combines and fix; Other follows closely the body leading edge and then welds an ailhead that is provided with inner bolt hole.

Because the nail body and the head of a nail are to be formed in one in the utility model, therefore, make that the processing of the nail body and the head of a nail is more simple and easy, and more meet manufacturer reduces manufacture cost to the blind rivet production requirement requirement; In addition, ailhead is the weldering linkage structure with the nail body, so intensity is higher, satisfying user's demand, thereby reaches the purpose of this utility model.

The explanation of accompanying drawing drawing:

Describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof.

See also Fig. 5, shown in Figure 6, the utility model mainly is made up of a nail body 7 and an ailhead 8, wherein this nail body 7 is by the nail body 7 that is rolled into a hollow tube-shape after the lamellar body punching press, its hypomere is provided with several warpage sheets, and ora terminalis extends a junction 74 on nail body 7, the other end of this joint 74 is then received a head of a nail 73, these head of a nail 73 its ora terminalis are provided with a card knot sheet 731, when system is used for the head of a nail 73 with 7 combinations of nail body, be plugged on the nail body 7 in the set breach 75 of ora terminalis, it forms the heads of a nail 73 and follows closely two immovable points that body 7 combines with joint 74; In addition, 71 welding one of the leading edge of ruthenium body 7 are provided with the ailhead 8 of inner bolt hole 81, and make this ailhead 8 its bottoms establish a flange 82 to be inserted in behind the endoporus of nail body 7 its leading edges 71 so that ailhead 8 to be provided, this flange 82 just is resisted against the periphery of nail body leading edge 71, and form a closing line C, be beneficial to being welded to connect of ailhead 8 and leading edge 71.

See also shown in Figure 6ly again, ailhead 8 is provided with endoporus 81, can provide the thread section 21 of a long bolt 3 to be spirally connected with it, with when connecing the nail rifle and connect this long bolt 2, forces warpage sheet 72 warpages.

In sum, the utlity model has and strengthen blind rivet head tensile strength, and make the processing official who follows closely the embodiment head of a nail, and meet the requirement that manufacturer produces blind rivet, solve the defective of habit formula blind rivet effectively for simple and easy.
