Handle linkage mechanism

Abstract

This invention relates to a handle linkage mechanism, comprising: a base, including two plate edges, a receiving space, two guide grooves and a limiting groove; a linkage, including two connecting rods and a pressure plate; a sliding seat, pivotally connected to the two connecting rods, the sliding seat having a locking member and a channel for accommodating the hook of the locking member pivotally connected inside, and the sliding seat being locked to the two guide grooves of the base by two fasteners, with a sliding groove and a guide rail in an engaging shape between the sliding seat and the base; and a handle, including a connecting plate pivotally connected to the linkage and the base, with an operating part extending from one side of the connecting plate and a hook at the end, the multi-link structure formed between the base, the linkage and the handle simultaneously controlling the sliding of the sliding seat on the base and the operation of the locking member pivotally connected inside the sliding seat engaging or disengaging from the positioning part of the locking seat.

Claims

1. A handle linkage mechanism, comprising: A base, fixed to the side of a predetermined chassis, the base having a receiving space between two convex plate edges, two parallel hollow guide grooves on one side of the receiving space, and a limiting groove extending from the receiving space between the two guide grooves; a linkage, adjacent to the base and having a distance between them, the linkage including two connecting rods and a pressure plate located between the two connecting rods; A sliding base is pivotally connected to one side of the two connecting rods of the linkage and housed in the receiving space. The sliding base has a locking member pivotally connected inside, which can be engaged with the positioning part of a latching seat fixed to the side of a predetermined cabinet. The locking member includes a swing rod that can abut against the limiting groove. The sliding base has a hollowed-out channel for accommodating the locking member away from the hook at the pivot point. The sliding base is locked to the two guide grooves of the base by two fasteners. On both sides of the sliding base and on the opposite inner sides of the two plate edges of the base, there are engaging grooves and guide rails, allowing the sliding base to conform to... The device slides on the base; and has a handle, including a connecting plate pivotally connected to the other side of the two linkages of the linkage, and the connecting plate is pivotally connected to the two plate edges of the base. An operating part extends from one side of the connecting plate and has a hook at the end of the operating part that can be snapped into the preset chassis to form a storage state. When the handle is in the open state, the linkage pivotally connected to the connecting plate drives the locking member to rotate and disengage from the positioning part of the latch seat, and the sliding seat slides away from the accommodating space of the base, so that the predetermined chassis can be pulled out of the predetermined cabinet.

2. The handle linkage mechanism as described in claim 1, wherein the base is provided with a plurality of locking holes for a plurality of preset screws to pass through, and both sides of the plate are provided with through holes for the handle to be pivotally connected.

3. The handle linkage mechanism as described in claim 1, wherein each of the two links of the linkage has a first fixing groove at both ends for pivoting the sliding seat and is open, and a second fixing groove at both ends for pivoting the handle and is also open, wherein the first fixing groove is positioned by passing through a first pivot with a gear-shaped locking mechanism at both ends; and the second fixing groove is positioned by passing through a second pivot with a gear-shaped locking mechanism at both ends.

4. The handle linkage mechanism as described in claim 1, wherein the sliding seat has a storage chamber for accommodating the locking member and the storage chamber is connected to the outside to form the channel, and the two sides of the sliding seat are provided with shaft cavities and engagement grooves that penetrate the storage chamber, the shaft cavity is for pivoting the linkage member, and the engagement groove is for the locking member to be aligned through the groove and to be positioned through the shaft rod.

5. The handle linkage mechanism as described in claim 1, wherein the sliding seat has an arc-shaped abutment surface on the other side of the channel, the abutment surface being supported by the also arc-shaped pressure plate.

6. The handle linkage mechanism as described in claim 1, wherein the sliding seat has two locking grooves on the bottom side of the corresponding channel for the two locking fasteners to engage, and a contact surface that can abut against the latch seat is formed at the front end of the corresponding channel, and the locking fastener includes a head that abuts against the surface of the base, a rod extending from the head that is located in a guide groove, and a fixing part extending from the rod that has external threads and engages with the locking groove of the sliding seat.

7. The handle linkage mechanism as described in claim 1, wherein the locking member has a through-hole positioning pin, and a swing rod is provided outside the positioning pin for a connecting portion at one end to be fitted, and the swing rod can rotate at the positioning pin, and the other end of the swing rod has an arc-shaped top holding portion that abuts against the limiting groove of the base, and a positioning groove is recessed between the connecting portion and the top holding portion of the swing rod.

8. The handle linkage mechanism as described in claim 7, wherein the locking member has a through-shaped shaft, and an elastic body made of a torsion spring is sleeved on the outside of the shaft, one end of the elastic body abutting against the inner wall of the receiving chamber of the locking member and the other end being positioned in the positioning groove of the swing rod.

9. The handle linkage mechanism as claimed in claim 1, wherein the handle is provided with a first cylinder at an adjacent edge of the base for the linkage to be pivotally connected via a second pivot, and a second cylinder near the center for the base to be pivotally connected via a shaft rod, and an elastic member made of a torsion spring is sleeved on the outside of the shaft rod, one end of the elastic member abutting against the inner side of the connecting plate of the handle and the other end being positioned in a positioning hole on the edge of the plate of the base.

10. The handle linkage mechanism as claimed in claim 9, wherein the length of the first shaft cylinder is greater than that of the second shaft cylinder, and the height of the second shaft cylinder on the connecting plate is greater than that of the first shaft cylinder.
