Embodiment Construction

[0017] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0018] Such as Figure 1~4 As shown, the present invention mainly includes a nail body 1, a locking sleeve 3 and a nail core 5. One end of the nail body 1 is provided with a nail body hole 2 along the axial direction, and the nail body hole 2 is connected to the nail core 5. The locking sleeve 3 is axially provided with a through inner hole 4 of the locking sleeve, and the locking sleeve 3 is tightly fitted on the nail core 5 in the inner hole 2 of the nail through the inner hole 4 of the locking sleeve.

[0019] One end of the nail core 5 is a circular nail head 6 , and the lower end of the nail head 6 is connected to the lower part 9 of the nail core. A locking groove 7 and a breaking groove 8 are provided at the junction of the nail head 6 and the lower part of the nail core 9 . The nail head 6 is located between the nail body 1 and the locking sl...

Abstract

The invention relates to a security type self-plugging rivet, and particularly relates to a shockproof, waterproof and locking type self-plugging rivet in an electric device industry, belonging to the technical field of a fastening piece. The security type self-plugging rivet comprises a locking sleeve; a through locking sleeve inner hole is axially arranged on a locking sleeve; the locking sleeve is tightly sleeved on a rivet core in a rivet body inner hole through the locking sleeve inner hole; a rivet head is arranged at one end of the rivet core; the lower end of the rivet head is connected at the lower part of the rivet core; and a locking groove is arranged on the connection position of the rivet head and the lower part of the rivet core. The security type self-plugging rivet provided by the invention has a simple, compact and reasonable structure, and is used for fastening and sealing in a riveted manner; the resistance of the rivet to transverse vibration is improved; and structural pieces with large and non-overlapped drill holes can be normally riveted.

Description

technical field [0001] The invention relates to a safety type blind rivet, in particular to a shockproof, waterproof and anti-loosening type blind rivet which can be used in the electric appliance industry, and belongs to the technical field of fasteners. Background technique [0002] The blind rivet is a kind of rivet for single-sided riveting, which must be riveted with a special tool—a riveting gun (manual, electric, pneumatic). When riveting, the core of the blind rivet is pulled by a special riveting gun to expand the riveting body and play a riveting role. This type of rivet is especially suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting must be done from both sides), so it is widely used in construction, automobiles, ships, aircraft, machines, electrical appliances, IT, furniture and other products. Among them, open-type oblate head blind rivets are the most widely used, countersunk head blind rivets are suitable for riveting o...
