Abstract
The utility model provides an improved self-tapping self-plugging rivet which comprises a rivet body and a rivet core; the rivet body is tubular; one end of the rivet body is provided with a rivet cover of a radial outer boss; one end of the rivet core is provided with a rivet head; a plurality of grooves are arranged at a part on the rivet core which is close to the rivet head; the rivet head of the rivet core has a circular drill bit-shaped structure with a sharp tail; and the diameter of the rivet head is a little more than the outer diameter of the tubular body of the rivet body. The improved self-tapping self-plugging rivet has the advantages and the beneficial effects that: when the novel self-tapping self-plugging rivet is used, the rivet head of the rivet core is provided with a certain drilling capability, and a product can be directly hit into an opposite object if a special electric drill is matched for use; then when the rivet is pulled out, the rivet is directly self plugged, the operation can be completed only by one step, procedures are simple, the operation efficiency is greatly improved, and simultaneously manpower is saved; and a drill bit is prevented from being used by mistake.
Description
Technical field
The utility model belongs to the break mandrel blind rivet field, especially relates to a kind of improved self-taped type self-plugging rivet.
Background technique
Self-plugging rivet is often to use the screw commonly used that is seen everywhere, and generally is mainly aluminium section bar, is widely used in industries such as machinery, building.Existing self-plugging rivet is generally as shown in Figure 1, comprises nail body 1 and nail core 2, and nail body 1 is a tubulose, and the one of which end is provided with the radially nail lid 3 of outer lug boss, and an end of nail core 2 is provided with crown ailhead 4, and part near ailhead is provided with some grooves 5 on it.The defective that existing product exists is: flow chart is loaded down with trivial details, when carrying out this operation, must utilize electric drill and drill bit punching on the thing relatively earlier; Use special instrument then, the product extruding is close on the relative thing, make between the two articles and combine closely; At last; Manually extract nail core 2 out with manpower, make two relative things of product locking, operating efficiency is lower; Also have, body 1 comes off easily if employed outside diameter, can make nail greater than ailhead 4 external diameters, and outside diameter then can cause product to squeeze into less than ailhead 4 external diameters.
Summary of the invention
It is simple that the problem that the utility model will solve provides a kind of flow chart, the improved self-taped type self-plugging rivet that is difficult for makeing mistakes.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: improved self-taped type self-plugging rivet comprises nail body and nail core; The nail body is a tubulose; The one of which end is provided with the radially nail lid of outer lug boss, and an end of said nail core is provided with ailhead, and position near ailhead is provided with some grooves on it; The ailhead of said nail core is the drill bit shape structure of circular fine stern, and the outer diameter of ailhead is slightly larger than the outer diameter of nail body tube.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, operation is simple, improves operating efficiency, uses novel self-taped type self-plugging rivet; The ailhead of its nail core possesses certain punching ability, is used special electric drill, can directly product be squeezed into relative thing, then when withdrawing from; Directly loose core, only need a step, get final product complete operation; Come complete operation and need not to re-use drill bit and employ manpower, improved operating efficiency greatly, saved manpower simultaneously; Avoid the novel self-taped type self-plugging rivet of generation of operate miss in addition; With original circular ailhead that does not have point, change the drill bit shape structure of circular fine stern into, its external diameter is slightly larger than the outer diameter of nail body tube; Use specialist tools; Product is directly squeezed into, need not to use drill bit, avoid drill bit to use wrong generation.

Fig. 2 is the schematic representation of the utility model;
Fig. 3 is the ailhead plan view of the utility model.
Among the figure:
1, nail body 2, nail core 3, nail cover 4, ailhead 5, groove
Embodiment
As shown in Figure 2, a kind of improved self-taped type self-plugging rivet of the utility model comprises nail body 1 and nail core 2; Nail body 1 is a tubulose; The one of which end is provided with the radially nail lid 3 of outer lug boss, and an end of said nail core 2 is provided with ailhead 4, and part near ailhead is provided with some grooves 5 on it; The ailhead 4 of said nail core 2 is the drill bit shape structure of circular fine stern, and the outer diameter of ailhead 4 is slightly larger than the outer diameter of nail body 1 tube.
The working procedure of this instance: novel self-taped type self-plugging rivet, be used special electric drill, directly product is squeezed into relative thing, when withdrawing from, directly loose core then, only need a step, get final product complete operation.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
