Description

Locking device for interface card

Technical Field

The present utility model relates to a locking device for an interface card (or called an interface card (INTERFACE CARD)), and more particularly, to a locking device which is capable of forming a simple intuitive operation by enabling a latch member to move linearly in a first direction to be locked above a positioning portion after moving backward in a second direction when a positioning portion of a preset interface card is contacted with a top side of the latch member when the preset interface card is inserted into a slot from top to bottom; when the preset interface card is to be pulled out from the slot, the operation part of the force application part which is positioned at the position where the preset circuit board is not shielded by the mechanism is only required to be pressed down, the push block is contacted with one side of the lock catch part and linearly pushed towards the second direction by the rotating force, and meanwhile, the propping surface positioned at the suspension end of the force application part is upwards propped against the lower edge of the positioning part of the preset interface card and pushes the preset interface card to upwards displace from the slot, so that the operation of unlocking and easy pulling of the preset interface card by a hand tool are not required.

Background

The display card occupies an extremely important position in the computer component, and the display card with high operation power inserted on the motherboard is provided with a heat dissipation structure (such as a heat dissipation fin and a fan) with a positive body, and an air-cooled tower type radiator or a water-cooled heat dissipation mechanism arranged on a Central Processing Unit (CPU), wherein the front heat dissipation mechanism occupies an extremely large space of the motherboard, and if the display card is to be pulled out from the motherboard for cleaning, maintenance or replacement, a user can hardly push and release the unlocking structure by extending hands to the side of the display card slot.

Because the unlocking structure of the display card is not easy to be contacted by hand, some people can press the unlocking structure by a hand tool (such as a screwdriver) or a special rod-shaped tool, but the method still needs a certain skill and hand stability, otherwise, once the hand tool falls onto a motherboard, electronic components can be damaged, and the unlocking structure is easy to be worn or damaged after being contacted with the hard hand tool for a long time. Moreover, the display card has a certain weight and volume, which is usually required to be pulled out by two hands, and one hand is required to press the unlocking structure, and the other hand is required to pull out the display card, which is not easy and not smooth to operate, so that the inconvenience of the pulling-out operation of the display card is required to be studied and improved by those who are to be engaged in the industry.
