A combination rivet

Abstract

The invention belongs to the technical field of rivets, and particularly relates to a combined rivet comprising a hollow rivet and a solid rivet. A fixing block is arranged on the middle portion of the hollow rivet. A first through groove and a second through groove are formed in the two ends of the hollow rivet correspondingly and are located in the two sides of the fixing block correspondingly.A first cavity and a second cavity are formed in the solid rivet. A clamping connection module is arranged on the portion, located inside the first cavity, in the solid rivet. An attraction module isarranged at the position, corresponding to the second through groove, on the solid rivet. The position, corresponding to the first through groove, on the solid rivet is fixedly connected with an extrusion block. The clamping connection module comprises arc-shaped clamping blocks. The arc-shaped clamping blocks are connected with the inner wall of the first cavity in a rotating manner. One end of each arc-shaped clamping block is fixedly connected with a pull rope. According to the combined rivet, multiple clamping connection can be conducted on the solid rivet and the hollow rivet through thearc-shaped clamping blocks, limiting claws and arc-shaped elastic sheets, and the connection strength between the solid rivet and the hollow rivet is improved.

Description

technical field [0001] The invention belongs to the technical field of rivets, in particular to a composite rivet. Background technique [0002] A rivet is a part that uses its own deformation or interference connection to realize the joint of two parts during the riveting process. There are many types of rivets and they are widely used in a wide range of applications. Most of them are made of aluminum alloy. Generally, in some occasions where corrosion is prone to occur, new requirements are put forward for the quality of rivets, which must not only be able to complete the riveting function, but also have anti-rust functions to ensure that they can work well in corrosive environments. The difference between rivets and commonly used nails or screws is that when the object is fixed by the rivet, it cannot be removed in a non-destructive way like a nail or screw. The rivet or object must be destroyed to separate the rivet from the object, and the rivet is in It is easy to dam...

Problems solved by technology

However, in the process of using this type of rivet, because only one clamping structure is used for clamping, the connection is not strong enough, which may easily cause the rivet to fall off, thereby causing the parts to fall off and cause an accident. Therefore, a combined rivet is proposed, which can When installing rivets, perform multiple clamping connections to effectively improve the firmness of the rivet connection and prevent the rivets from falling off, thus ensuring the normal use of the rivets
