Description

Quick release device for slide rail and cable management rack

【Technical field】

The invention relates to a quick release device for a slide rail and a cable management frame, and relates to the related technical field of a quick release device for quickly combining or separating a cable management frame for a slide rail.

【Background technique】

In the prior art, for example, Taiwan Province of China Invention Patent No. I446665 "Connecting Device for Cable Management Frame and Slide Rail", although it discloses a quick release device, and is locked by a stop end through an insert. The resistance block of the elastic arm is blocked to achieve the purpose of quickly assembling the line frame and the slide rail (please also refer to Figure 6 of the above-mentioned Taiwan Provincial Invention Patent No. I446665). However, it has been checked that it has operation The advantages of non-directional and thin design, but there are still the following shortcomings:

1. The end face of the resisting block of the elastic arm is thin and narrow, so the area of its opposite end is also narrow, which leads to a less stable clamping effect. The first cable management arm and the second cable management arm of the cable management frame The arm is movably connected, and along with the inner and outer rails of the slide rail, the non-linear opening and closing stretches in the front and rear directions, so it may also lead to the disengagement of the insert, which may cause the cable management frame to fall and affect the safety.

2. When the user wants to press and exert force to make the resisting block of the elastic arm detach from the end of the insert, it is difficult to control the magnitude of the pressing force. If the pressing force is small, the resistance cannot be completely removed. It is necessary to press and apply a lot of force to ensure that the resisting block of the elastic arm is completely separated from the end of the insert, so the elastic arm is easily deformed or damaged after long-term use, and the resisting action is inaccurate, so it is reasonable There is a risk that the wire rack will fall and affect the safety.
