Abstract

The invention provides a bolted connection structure capable of effectively reducing bolt movement and a lock washer thereof, and an automobile luggage rack with the structure. The center of the lock washer (1) is provided with a round hole (2), and the diameter of the round hole (2) is slightly larger than the external diameter of threads of a bolt (3) to be locked by the round hole (2), so thatthe round hole (2) and the bolt (3) are in interference fit after the bolt (3) is screwed in; and the periphery of the round hole (2) is provided with a plurality of grooves (4) among which a plurality of deformation teeth (5) are formed. In the bolted connection structure suitable for the automobile luggage rack, the bolt (3) passes through two connected pieces (6 and 7), the lock washer (1) is screwed in or pressed in the bolt (3), and the deformation teeth (5) are deformed to be embedded into the threads of the bolt (3); or the bolt (3) passes through an upper connected piece (6), the lockwasher (1) is screwed in or pressed in the bolt (3), the bolt (3) passes through a lower connected piece (7), and a nut (8) is screwed in.

Description

Bolted connection structure and its stop washer and luggage rack technical field The invention relates to a bolt connection structure and its stop washer, and an automobile luggage rack adopting the structure. Background technique Generally, when two parts are to be connected with freely movable bolts and nuts, if there is no structure to limit the bolts, the bolts will move upwards when the nuts are installed, causing inconvenience in installation. Especially for products such as luggage rack installation, where one bolt and nut are outside the car and the other is inside the car, it is inconvenient to hold down the bolt, the demand for a small structure that can limit the bolt's upward movement is particularly strong. Common structures include some stop gaskets, self-locking structures, etc., but when the installation and operation space is limited, how to stop becomes a problem. The present invention is just to solve this problem. Contents of the invention The te...
