Problems solved by technology

[0006] The invention solves the defects that the existing fastener connection needs to process multiple threads on the connector for fastening, the processing time is long, and the processing efficiency is easily reduced, and provides a fast connection structure of the fastener. Process a connection hole whose edge only forms one thread that matches the thread shape of the fastener, thereby improving processing efficiency
[0007] The present invention also solves the problem that there is no correspondence between the thickness of the existing connecting piece and the pitch of the fastener, and the connecting hole on the connecting piece tends to have less than one thread, which affects the fastening strength, and more than one thread causes troublesome processing. The defect is to provide a fast connection structure for fasteners. The pitch of the fasteners selected for fastener connection is the same as the plate thickness of the connectors. A connection hole with only one thread is processed on the connectors, which is convenient for processing. easy connection
[0008] The present invention also solves the problem that the existing fasteners need to use a screwdriver to be easily affected by the assembly space of the fasteners, and is prone to the problem that the space is small and cannot be assembled, and provides a fast connection structure of the fasteners, the fasteners are pre-connected To one of the connecting parts, the other connecting part is provided with a socket and a chute, which is fastened by inserting and sliding, and is not affected by the assembly space of the fastener

Embodiment

[0035] Embodiment: a kind of screw fast connection structure (see attached figure 1 ), screw 1 connects the two connectors. Among the two connecting parts, the one close to the screw cap is the first connecting part 2 , and the one far away from the screw cap is the second connecting part 4 . The first connecting piece is provided with a combined connecting hole 3 , and the second connecting piece is provided with a threaded connecting hole 5 . The combined connection includes a socket 8 and a chute 9 which communicate with each other. The diameter of the socket is larger than the diameter of the screw cap, and the width of the chute is adapted to the diameter of the screw thread section (see attached image 3 ). The edge of the threaded connection hole forms a truncated cone 6 shape. When the second connecting piece is overlapped with the first connecting piece and fastened, the truncated cone on the second connecting piece is separated from the first connecting piece. Lar...

Embodiment 2

[0044] Embodiment 2: A screw quick connection structure, the edge of the threaded connection hole is provided with a frustum 6, and the frustum is provided with an axial connection part at a radial position, and the axial connection part forms a pitch around the threaded connection hole The height difference, the side of the axial connection part facing the center of the threaded connection hole is provided with a groove that matches the thread profile of the screw. The screw is screwed into the threaded connection hole, and the crest of the thread is just at the bottom of the groove. Refer to Example 1 for all the other structures.

Abstract

The invention relates to a fastener fast connecting structure and method and a steel cabinet using the connecting structure. By means of the fastener fast connecting structure and method, the defects in the existing fastener connection that a plurality of threads are required to be machined on a fastener to conduct fastening, machining time is long, and machining efficiency is easy to reduce are overcome. Two connecting pieces are connected through the fastener, a threaded connecting hole is formed in a second connecting piece, a thread is stamped on the periphery of the threaded connecting hole, a central angle of the thread is at least 180 degrees, and the thickness of the periphery of the threaded connecting hole is matched with the thread pitch of the fastener. A connecting hole in a first connecting piece is used for connecting the fastener fast, and the fastener is pre-fastened on the threaded connecting hole and connected with the connecting hole in the first connecting piece fast. The thickness of the periphery of the threaded connecting hole is matched with the thread pitch of the fastener, the periphery of the threaded connecting hole is used as a connecting thread profile, the number of the thread profile is one, the thread profile can be manufactured through stamping during machining directly, machining is simple, and machining efficiency is improved.

Description

technical field [0001] The invention relates to a connection structure and a connection method and a corresponding cabinet body, in particular to a fast connection structure of fasteners that improves assembly speed and reduces assembly difficulty, a connection method and an iron cabinet using the connection structure. Background technique [0002] There are many types of existing connection structures, and the application occasions are also relatively wide. After years of technological evolution, welded joints, threaded joints and rivet joints are the most commonly used joint structures in steel joint structures. These three connection structures can be used universally, but in some occasions, specific connection structures are also required. For example, welded joints are suitable for fixed and non-detachable joints, threaded joints are suitable for repeated detachable joints, and rivet joints are destructive. detachable connection occasions. [0003] Threaded connection...
