Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. But it is not used as any limitation basis for the present invention.

[0033] A new locking pin assembly, including a mounting plate 2, a buckle plate 3, a driving head 4, a locking key 5 and a rivet 6;

[0034] The aforementioned mounting plate 2 includes: mounting plate hole 40, mounting plate plane I 41, mounting plate plane II 42, mounting plate connection hole 43 and mounting plate side 44; mounting plate hole 40 and the small cylindrical surface 10 of the drive head adopt clearance fit, and the fit clearance is 0.05 ~0.1mm, to ensure that there is no blockage when the mounting plate hole 40 and the small cylindrical surface 10 of the drive head work;

[0035] The mounting plate 2 is made of carbon structural steel 20# steel, which has strong versatility and low price, and meets the requirements of use.

[0036] The aforementioned pinch ...

Abstract

The invention provides a locking pin assembly and an application method thereof. The locking pin assembly comprises a mounting plate, a buckle plate, a driving head, a locking key and a rivet. A locking key matching cylindrical surface of the locking key with a locking key small cylindrical surface penetrating through a mounting plate hole in the mounting plate is in transition fit with a driving head mating hole in the driving head; a locking key rivet hole of the locking key and a driving head rivet hole of the driving head are aligned with each other and riveted together through the rivet, and it is guaranteed that no relative looseness exists between the driving head and the locking key; the mounting plate is riveted to a mounting base body I in the mode that mounting rivets pass through mounting plate connecting holes, the buckle plate is riveted to a mounting base body II in the mode that mounting rivets pass through buckle plate connecting holes; in the closing process, a locking key 3D locking head of the locking key is aligned with a kidney-shaped buckle plate hole of the buckle plate, a line-shaped tool is used for rotating a driving groove in the driving head to drive the locking key to rotate the locking key 3D locking head, and then the locking key 3D locking head and the kidney-shaped buckle plate hole are locked according to the screw principle. The locking pin assembly is small in size, low in weight, reliable in connection and particularly suitable for a movable connection unit requiring a narrow working area.

Description

technical field [0001] The invention relates to a locking pin assembly and a using method thereof, and belongs to the technical field of movable link fasteners. Background technique [0002] At present, in the design of mechanical parts in the high-tech field, high-end fasteners with light weight, small size and high reliability have high technical requirements, complex structures, difficult processes and expensive prices. In modern mechanical design, it is often required to use smooth and fast assembly, reliable connection, and certain working pressure after assembly, which is convenient for frequent opening and closing of movable connection fasteners. To meet the above requirements, conventional designs need to adopt complex mechanical structures. . Contents of the invention [0003] The invention provides a locking pin assembly which can solve the problem of smooth and fast matching, reliable connection, certain working pressure after assembly, and convenient frequent ...
