Latch type locking device for connection of thin-wall pieces under large impact vibration

Abstract

The invention relates to a latch type locking device for connection of thin-wall pieces under large impact vibration. The latch type locking device for connection of the thin-wall pieces under large impact vibration comprises a locking device and a lock sleeve, wherein the locking device comprises a locking shaft, a handle, a spring and a mounting seat; the spring 5 is positioned in a step hole inthe mounting seat 6; the locking shaft penetrates through the step hole in the mounting seat, and the other end of the spring is clamped on a step surface of the locking shaft; a two-step through hole is formed in a side wall of a large end of the locking shaft, under the state that the spring is not stressed, the central axis of the two-step through hole is superposed to the central line of a U-shaped hole of the side, which is away from a round hole, of the side wall of one end of the mounting seat; a step end of the two-step through hole is positioned on the side which is away from the U-shaped hole; and the lock sleeve 2 is positioned at one end of the large end of the locking shaft 3, and is connected with the locking shaft 3 through a central hole thereof. By the device, the thin-wall pieces can be reliably connected under large-impact vibration, and as long as the related fit sizes of connection positions are changed, the latch type locking device can be widely used for connection of various thin-wall pieces under large impact vibration.

Description

technical field [0001] The invention belongs to the field of heavy machinery, in particular to a bolt-type locking device for connecting thin-walled parts under large impact and vibration Background technique [0002] In our country, the connection of thin-walled parts in the environment of large shock and vibration mostly adopts traditional hasp locks. The shaft pin on the lock seat rotates, and the dead bolt is integrated with the lock core. The dead bolt seat is provided with a groove corresponding to the dead bolt projection, and the lock body can cover the dead bolt seat. This structure can realize fast and reliable connection at the connection of thin-walled parts with small shock and vibration, but at the connection of thin-walled parts with large shock and vibration, after shock and vibration in all directions, the buckle lock of this rectangular parallelepiped structure is due to the various parts It cannot move well with the joint part at the same time, resulting ...

Problems solved by technology

This structure can realize fast and reliable connection at the connection of thin-walled parts with small shock and vibration, but at the connection of thin-walled parts with large shock and vibration, after shock and vibration in all directions, the buckle lock of this rectangular parallelepiped structure is due to the various parts It cannot move well with the joint part at the same time, resulting in uneven force on the overall shape and the lock tongue, which will deform or break the hasp lock, resulting in failure of the locking function and reduced working reliability
