Embodiment Construction

[0018] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0019] like Figure 1~4 As shown, the present invention is a rivet type bolt, comprising a nail body 1 and a nail core 5, the nail body 1 is provided with a counterbore 2 and a through hole 3 coaxial therewith, and the diameter of the counterbore 2 is larger than that of the through hole 3 diameter, the nail core 5 runs through the through hole 3 and the nail head 6 at the upper end of the nail core 5 is clamped on the boss formed by the counterbore 2 and the through hole 3, and the lower end of the nail head 6 is connected to the nail mandrel rod 10, so A fracture groove 8 is set on the nail mandrel 10, and the fracture groove 8 divides the nail mandrel 10 into upper and lower parts, the upper end is provided with a screw 7, and the lower end is a polished rod; the screw 7 is covered with a protective cover 4, so The lower end of the protective sleev...

Abstract

The invention relates to a rivet type bolt, in particular to a bolt capable of being used in vibration resistance, tightness and single-face connection in automobile and aviation industry, and belongs to the technical field of fasteners. The rivet type bolt comprises a rivet body and a rivet core, wherein a counter bore and a through hole which are coaxial with the rivet body are arranged on the rivet body, the diameter of the counter bore is larger than that of the through hole, the rivet core penetrates through the through hole, and a rivet head at the upper end of the rivet core is clamped on a boss formed by the counter bore and the through hole. The rivet type bolt is characterized in that the lower end of the rivet head is connected with a rivet core rod, a fracture groove is arranged on the rivet core rod and divides the rivet core rod into an upper part and a lower part, threads are arranged at the upper end of the fracture groove, and a polish rod is arranged at the lower end of the fracture groove; and a protective sleeve is sleeved on the threads, the lower end of the protective sleeve is clamped in the fracture groove, and a chamfer is arranged at the upper end of the rivet head. The rivet type bolt is simple, compact and reasonable in structure, and firm and sealed in connection, and improves resistance to single-face and blind hole connection vibration particularly in simple operations of single-face blind hole connection.

Description

technical field [0001] The invention relates to a rivet-type bolt, in particular to a single-sided, blind-hole connection and sealing bolt which can be used in various industries, and belongs to the technical field of fasteners. Background technique [0002] A bolt is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut to connect two workpieces with through holes and not too thick. It is a standard part. . This type of bolt is especially suitable for connection occasions that need to be connected from both sides, so it is widely used in general connection occasions in construction, automobiles, ships, aircraft, machines, electrical appliances, IT, furniture and other products. [0003] At present, the production of the automobile and aviation industries is developing rapidly, and the occasions where users need riveting are also diversified (such as single-sided, blind holes), so higher requirements are pu...
