Abstract
A liquid pump unit includes a chassis box having a front opening and a back panel that includes fluid and electrical interfaces. The liquid pump unit also includes a tray box that supports a pump assembly. The pump assembly includes fluid couplers and electrical connectors respectively configured to mate with the fluid and electrical interfaces. The liquid pump unit further includes a latch mechanism disposed between the chassis box and the tray box. The latch mechanism includes a rotatable lever, a latch and a connecting bar. The latch is configured to engage a catch-pin that protrudes from the back panel. Rotation of the lever drives the connecting bar to actuate the latch to engage the catch-pin and cause the fluid couplers and electrical connectors to respectively connect with the fluid and electrical interfaces.
Claims20
A liquid pump unit, comprising:
- a chassis box defining a bay and having a front opening and a back panel that includes fluid and electrical interfaces;
- a tray box configured to be slidably received within the bay, the tray box supporting a pump assembly that includes fluid couplers and electrical connectors respectively configured to mate with the fluid and electrical interfaces;
- and
- at least one latch mechanism disposed between the chassis box and the tray box, the latch mechanism including:
- a rotatable lever extending through the front opening of the chassis box;
- a latch configured to engage a catch-pin that protrudes from the back panel;
- and
- a connecting bar coupling the lever and latch,
- wherein rotation of the lever drives the connecting bar to actuate the latch to engage the catch-pin and cause the fluid couplers and electrical connectors to respectively connect with the fluid and electrical interfaces.
A latch mechanism for securing a pump assembly within a chassis having a chassis box, the latch mechanism comprising:
- a lever having a first lever-arm and a second-lever arm;
- a latch having a latch-arm and a hook that is configured to engage a retaining cut-out of a catch-pin;
- a connecting bar having opposite ends respectively pivotally coupled to the lever and the latch at corresponding pivot joints;
- and
- fixed pivot points respectively coupling the lever to a front end and the latch to a rear end of an inner panel assembly, wherein rotation of the lever about one of the fixed pivot points drives movement of the connecting bar such that a pivot joint of the connecting bar moves between positions inside and outside a tray box through a front opening of the chassis.
