Description

locking device

The present invention relates to a structure of a locking device; in particular, it refers to a technique in which an operating part is arranged and combined with an actuating body to improve the length/specification of a conventional structure limited by the configuration space.

Apply locking devices or similar devices to be installed on the cover structure of computer/electronic equipment, server chassis, etc., to provide personnel to operate the computer/electronic equipment to open/close or control the cover structure to lock and close the chassis body, avoiding It is a known art that the components or parts inside the case are exposed, or the operating cover is opened so that personnel can configure, repair, etc. the internal components of the case.

For example, US 6174007 B1 "ACTUATOR ASSEMBLY", US 7201407 B2 "SLIDING PANEL LATCH", US 8256737 B2 "LEVERAGE DEVICE AND SYSTEM USING SAME", CN 110388148 A "Latch device", CN 207829660 U "Latch and including latch "Shell assembly" (that is, Taiwan No. 107207996 "shield latch"), CN 206685594 U "latch and housing assembly including the latch" (that is, Taiwan No. 106215877 "hood latch") patent cases, etc. , a typical example is provided.

This type of latch device usually includes a housing, an actuating handle and a sliding plate; a push button is provided at one end of the housing. The actuating handle has a pivot end matched with a spring, which is pivotally connected to the other end of the casing; the other end of the actuating handle is pivotally connected to the connecting rod, and the other end of the actuating handle is provided with a protrusion to allow the protrusion to be inserted into the push button, form a locked state. When the person presses the button to release the protrusion, the spring pushes the actuating handle to open, drives the sliding plate to move, and the connecting rod props up the actuating handle.

A problem related to the structure and operation application of the combined type of the conventional latch device is that, on the inherent length or specification of the housing, the structure of the actuating handle and the push button must be configured at the same time, that is, the length of the actuating handle must be shortened. It also affects the convenience of operation of the operating handle relatively, and this situation is not what we expect.

Typically, these references show skill in structural combination design and application of latches or similar mechanisms; Those who are familiar with it will be able to change its use form, which is different from the old method; in essence, it will also increase its application effect.

We found that an ideal structure of the latch device must be able to overcome or improve the issues discussed above, and should include the following design considerations:

1. Under the condition that the structure (or shell) has the same length or specification, the length of the actuating handle can be increased as much as possible, so that its length is greater than that of the conventional structure, so as to improve the safety of the latch device (or actuating handle) Ease of operation.

2. Further consideration is to provide a structural type in which the pressing operation structure can be directly combined with the actuating handle (or actuating body), and can still achieve the pressing operation structure and actuation without affecting or shortening the length of the actuating handle. The function of the smooth movement of the handle (or actuator).
