Description

Technical Field

[0001] The utility model relates to a screw-type core-pulling rivet. Background Art

[0002] Blind rivets are a type of rivet used for single-sided riveting, but they must be riveted with a special tool, a rivet gun. During riveting, the rivet core is pulled by a special rivet gun to expand the rivet body and play a riveting role. This type of rivet is particularly suitable for riveting occasions where ordinary rivets are inconvenient to use, so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products. As mentioned above, blind rivets require the use of a rivet gun, and a rivet gun is a professional tool. If an ordinary family wants to use rivets to fix some objects, they need to purchase a rivet gun, but the price of a rivet gun is relatively expensive.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The utility model aims to overcome the above problems and provides a screw-type blind rivet, which does not require a rivet gun when in use.

[0005] To achieve the above-mentioned purpose, the utility model provides a screw-type blind rivet, which includes a nail sleeve and a stud. The front side of the nail sleeve is provided with a limiting outer edge, and a channel running through the nail sleeve is opened in the front and back. A threaded hole is provided at the front port position of the channel. The stud is arranged in the channel and the front and rear ends are exposed to the nail sleeve. The stud is screwed with the threaded hole, and the rear end of the stud is provided with a boss to abut against the rear end of the nail sleeve. The stud is provided with a tearing groove in front of the boss, and a plurality of notches are distributed circumferentially on the side wall of the nail sleeve. The front end of the stud is provided with a concave hole for connecting a screwdriver.

[0006] In one or more embodiments, the concave hole is one of a straight concave hole, a cross concave hole, a triangular concave hole, a hexagonal concave hole and a plum blossom concave hole.

[0007] In one or more embodiments, the shape of the limiting outer edge is a regular hexagon or a regular pentagon.

[0008] In one or more embodiments, an inner convex rib and an outer convex rib are respectively provided on the inner side and the outer side of the mouth edge of the nail sleeve at the rear end, and both the inner convex rib and the outer convex rib are in a ring shape.

[0009] In one or more embodiments, the boss is in a ring shape and has a diameter greater than a diameter of the nail sleeve.

[0010] In one or more embodiments, the nail sleeve and the stud are both made of stainless steel.

[0011] Compared with the background technology, the utility model has the following effects: the screw-type blind rivet does not need to be used with a rivet gun, and a common screwdriver can be used for the rivet operation. The screwdriver is a common household tool and does not cause an increase in the use cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see attached Figure 1-3 The present application provides a screw-type blind rivet, which includes a nail sleeve 1 and a stud 2. The front side of the nail sleeve is provided with a limiting outer edge 3, and the nail sleeve is provided with a channel 4 that runs through the front and back. A threaded hole 5 is provided at the front port position of the channel. The stud 2 is arranged in the channel and the front and rear ends are exposed on the nail sleeve. The stud is screwed with the threaded hole. A boss 6 is provided at the rear end of the stud 2 to abut against the rear end of the nail sleeve 1. A tearing groove 7 is provided in front of the stud located in front of the boss 6. A plurality of notches 8 are distributed circumferentially on the side wall of the nail sleeve 1. A concave hole 9 for connecting a screwdriver is provided at the front end of the stud 2. Specifically, the concave hole 9 is one of a flat-blade concave hole, a cross concave hole, a triangular concave hole, a hexagonal concave hole and a plum blossom concave hole. A flat-blade concave hole and a cross concave hole are preferably used. A flat-blade screwdriver and a cross screwdriver are the most common types of household screwdrivers to improve the versatility of the screw-type blind rivet.

[0017] After the user passes the nail sleeve through the hole, he connects the concave hole with a screwdriver and rotates the stud to fix the top sleeve. The boss at the rear end of the stud moves forward to squeeze the rear end of the top sleeve, causing the rear end of the nail sleeve to gradually deform along the grooves until it contacts the two sides of the hole with the outer edge of the limit. At this time, the user continues to twist the stud, and the stud is immediately broken along the tear groove under the action of force.

[0018] The shape of the limiting outer edge 3 is a regular hexagon or a regular pentagon, so that the user can use a hexagonal wrench or a pentagonal wrench to connect the limiting outer edge, thereby fixing the nail sleeve.

[0019] The inner and outer sides of the edge of the nail sleeve 1 at the rear end are respectively provided with inner convex ribs 10 and outer convex ribs 11, both of which are ring-shaped. The inner convex ribs and the outer convex ribs can strengthen the structural strength of the edge at the rear end of the nail sleeve to avoid tearing problems at the edge.

[0020] The boss 6 is in a ring shape and has a diameter greater than that of the nail sleeve 1, so as to ensure that the boss can always abut against the nail sleeve and exert pressure on the nail sleeve to deform it.

[0021] The nail sleeve 1 and the stud 2 are both made of stainless steel, and the nail sleeve and stud made of stainless steel have good rust resistance.

[0022] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
