Lock apparatus

Abstract

The invention provides a locking apparatus, which particularly to improve the assembly structure of a guide member to reduce a number of man hours and cost and reliably reduce rattle caused by repetitive use and unusual noise caused by the rattle. The lock apparatus comprises: a lid (20) configured to turn to open and close an opening of a box; a rod (6) switchable between a locked position wherea tip of the rod projects to outside of the lid and an unlocked position where the tip is retracted to inside of the lid; and a guide member (5) attached to the inside of the lid and configured to slidably support the rod, and is characterized in that the lid (2) includes one of an engaging portion (29c) and an engaged portion (57b), and the guide member (5) includes the other one of the engagingportion and the engaged portion, and the engaging portion and the engaged portion are configured to move the guide member (5) in a direction intersecting a lid opening and closing direction to therebyfix and press-fit to each other without rattle.

Description

technical field [0001] The present invention relates to a locking device suitable for engaging or disengaging a lid body with or from a box side through a pair of levers that are separated or approached to each other. Background technique [0002] Figure 10A , Figure 10B The locking device disclosed in Patent Document 1 is shown, in which Figure 10A Shows the relationship of the locking device to the cover, Figure 10B The locking device is shown. This locking device 20 has: a cover body 13 that rotates to open and close the opening of the box; Switch between the release position and retreat to the inside of the cover; guide member (sliding guide) 22, which is installed on the inside of the cover, supports the rods 14, 15 in a slidable manner; the locking device 20 passes through each The rod engages or disengages from the locking recess on the case side. In addition, the guide member 22 is fixed to a boss provided on the rear surface side of the cover body 13 by bolt...

AI Technical Summary

Problems solved by technology

Specifically, in the above-mentioned locking device, in order to prevent the guide member from rattling, it needs to be fixed to the cover side with bolts, which requires an increase in the number of parts and an assembly man-hour.

In addition, even if the guide member is fixed with bolts, since the direction in which the bolts are pulled out is the same as the direction in which the cover is opened and closed, the bolts may loosen due to long-term use, resulting in rattling and abnormal noise.
