Mounting mechanism for retaining slide rail to chassis
View Patent ↗A mounting mechanism is disclosed. The mounting mechanism includes a chassis with an anchor member, a slide rail defining a mounting slot to receive the anchor member, and a retaining member slidably attached to the slide rail. A first end of the retaining member is pivotable attached to the slide rail. The retaining member comprises a stop surface and an inclined surface opposite to the stop surface formed from a second end of the retaining member. The anchor member slides in the mounting slot to drive the inclined surface of the retaining member to rotate the retaining member, when the anchor member rides over the stop portion, the retaining member is restored to make the stop surface of the stop portion retain the anchor member in the mounting slot of the slide rail.
1. A mounting mechanism comprising:
a chassis comprising an anchor member fixed to the chassis;
a slide rail defining a mounting slot for receiving the anchor member of the chassis; and
a retaining member comprising a main body, a pivot portion extending from a first end of the main body, a stop portion extending from a second end of the main body opposite to the pivot portion, wherein the pivot portion is pivotably attached to the slide rail, the main body is raised from the pivot portion and the stop portion, the pivot portion and the stop portion are in tight contact with the slide rail, the main body is spaced by a distance from the slide rail, the stop portion comprises a stop surface and an inclined surface opposite to the stop surface;
wherein the anchor member slides in the mounting slot to drive the inclined surface of the retaining member to rotate the retaining member to an upper position to allow the anchor member to ride over the stop portion, and when the anchor member rides over the stop portion, the retaining member is biased to rotate to a lower position to retain the anchor member in the mounting slot of the slide rail; and
wherein the stop portion is formed by bending a piece extending from an upper portion of the second end of the main body to be parallel to the main body.
2. The mounting mechanism of claim 1 , wherein the anchor member is a mushroom-shaped post, and comprises a neck portion and a head portion with a diameter larger than a diameter of the neck portion, the neck portion of the anchor member is slidable in the mounting slot of the slide rail, the head portion of the anchor member is engagable with the stop portion of the retaining member.
3. The mounting mechanism of claim 2 , wherein the mounting slot comprises a guiding portion for the anchor member entering into the mounting slot, and a positioning portion for engaging the neck portion of the anchor member.
4. The mounting mechanism of claim 1 , wherein the retaining member is made of an integrative resilient piece.
5. The mounting mechanism of claim 1 , further comprising a resilient member arranged between the retaining member and the slide rail, to restore the retaining member.
6. The mounting mechanism of claim 5 , wherein a bent portion extends from a bottom of the main body for locking a first end of the resilient member, a tab extends from the slide rail, for blocking a second end of the resilient member.
7. The mounting mechanism of claim 1 , wherein a limiting section is formed from a top of the pivot portion of the retaining member, a bulge extends from the slide rail for engaging with the limiting section, to limit the retaining member from further rotating.
8. The mounting mechanism of claim 1 , wherein the slide rail comprises a main wall and two sidewalls extending from opposite sides of the main wall, a cutout is defined in an upper sidewall of the sidewalls, for avoiding the upper sidewall interfering with the stop portion of the retaining member when the retaining member rotating.
