Locking device for slide rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional locking devices for server housings and drawers have complex structures and occupy significant space due to the use of hard metal transmission rods, which cannot be adjusted for spatial arrangement, leading to inefficiencies in positioning and orientation.
Innovation Solution
A locking device for slide rails featuring a slide rail with an outer and inner rail, a locking mechanism with a slide member and fastening member, and a driving mechanism using a traction mechanism and pull cords to move the slide member between fastened and released positions, allowing for adjustable locking and unlocking states without obstructing the inner rail's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard metal transmission rods are used to drive locking mechanisms, then reliable synchronous driving is achieved, but device complexity and occupied space increase significantly
Solution Approach 1:
The patent replaces the traditional hard metal transmission rod mechanism with a flexible cable system. The flexible cable connects the locking handle to multiple locking blocks, transmitting force through tension rather than rigid mechanical connection. This substitution maintains reliable synchronous driving while dramatically reducing structural complexity and occupied space.
Solution Approach 2:
The patent employs flexible cables instead of rigid transmission rods. These flexible cables can bend and adapt to spatial arrangements within the server housing, providing the necessary force transmission while occupying minimal space and allowing for adjustable positioning and orientation according to the spatial constraints of the application environment.
2Force
If hard metal transmission rods are used for locking mechanisms, then force transmission is reliable, but spatial arrangement flexibility is reduced
Solution Approach 1:
The flexible cable system can be routed through various paths and adjusted to fit different spatial arrangements within the server housing. The cable's flexibility allows it to accommodate different orientations and positions of locking mechanisms while maintaining effective force transmission capability.
Solution Approach 2:
The flexible cable system allows for dynamic adjustment of routing and tension, enabling the locking mechanism to adapt to different spatial configurations. The cable can be installed and adjusted to match the specific spatial requirements of various server housing arrangements while maintaining reliable force transmission.
3Reliability
If conventional locking devices are installed in server housing, then security function is achieved, but occupied space is significant
Solution Approach 1:
Replacing the rigid transmission rod system with flexible cables eliminates the need for large mechanical housings and complex linkages. The cable system can be installed in compact configurations, dramatically reducing the space required for the locking device while maintaining full security functionality.
Solution Approach 2:
The flexible cable system occupies minimal space compared to rigid mechanical transmission systems. The cables can be routed through existing spaces within the server housing structure, reducing the additional space required for the locking mechanism itself while maintaining effective force transmission for secure locking.

AI summary
A locking device for a slide rail includes a slide rail, a locking mechanism, and a driving mechanism. The slide rail has an outer rail and an inner rail, the inner rail being capable of moving to a retracted position and an extended position relative to the outer rail along opposite directions. The locking mechanism includes a slide member, a fastening member, and a stopping part formed on the slide member, the slide member being capable of moving to a fastening position and a released position along opposite directions. The driving mechanism includes a traction mechanism and a pull cord connecting the traction mechanism and the slide member. When the locking mechanism is in a locked state, the fastening member is obstructed by the stopping part, and when the locking mechanism is in an unlocked state, the stopping part does not obstruct the fastening member.
