Description

Quick release device for slide rail and cable management frame

The invention refers 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 slide rail and a cable management frame.

According to the prior art, such as the invention patent No. I446665 "connecting device for cable management frame and slide rail" patent case, it discloses a quick release device, and is resisted by a resilient arm through a resisting end of an insert It is locked to achieve the purpose of quickly combining the cable management rack and the slide rail (please also refer to Figure 6 of this I446665 patent case), but it has been checked that it has the advantages of non-directional operation and thin design , But there are still the following missing:

1. The end face of the resisting block of the elastic arm is thin and narrow, so the area of the opposite resisting end is also narrow, resulting in a less stable clamping effect. The first cable management arm system and the second cable management system of the cable management frame are not stable. The connection of the wire arms is movable, and non-linear opening and closing stretching movements are performed in the forward and backward directions of the inner and outer rails of the slide rail, so it may also cause the insert to detach, which may cause the cable management frame to fall and affect safety. .

2. When the user wants to press the force to disengage the resisting block of the elastic arm from the abutting end of the insert, it is difficult to control the magnitude of the pressing force. If the pressing force is small, it cannot be completely released from the resist. It is necessary to press a large amount of force to make sure that the resisting block of the elastic arm completely disengages from the abutting end of the insert. Therefore, the elastic arm is also easily deformed or damaged after long-term use, and the resistive action is inaccurate, which is also reasonable. The wire frame may fall, which may affect safety.

In view of this, the inventor finally created and designed a quick release device for slide rails and cable management racks after continuous research, improvement, and testing.

The main object of the present invention is to provide a quick-release device for a slide rail and a cable management frame, which can improve the stability of the quick-release hook hook pivoted by the buckle and the quick-release seat, and can prevent the buckle from detaching and causing The cable management frame is dropped, which also has better security. A secondary object of the present invention is to provide a quick release device for a slide rail and a cable management frame. When the snap ring and the quick release seat are to be disassembled and disassembled, there is no need to consider front-rear directionality, and the operation is convenient. Another object of the present invention is to provide a quick-release device for a slide rail and a cable management frame, which has a small component size and conforms to a thin design, and is particularly suitable for a thin slide rail.

A quick release device for a slide rail and a cable management frame, including a slide rail, a cable management frame, a quick release seat, a quick release hook, a torsion spring, a quick release cover, a buckle, a movable rack, etc. It is composed of components, so that when the buckle is inserted into the guide groove of the quick-release seat, the quick-release hook can be first pivoted by its linking wall, and the torque is pressed by one side of the quick-release hook When the spring is introduced into the open groove of the buckle first, the buckle of the quick release hook is located in the enlarged groove of the buckle, so that the quick release hook can be subjected to the elastic pressure of the torsion spring. It is pivoted and stopped by its retaining portion by the retaining portion of the retaining ring to prevent the retaining ring from detaching from the quick release seat to complete the assembly; and when it is desired to detach the retaining ring and the quick release seat, it is not necessary Considering the front-to-back directionality, the front protruding part or the rear protruding part of the quick release hook can be arbitrarily rotated to pivot the quick release hook and disengage the snap part from the stop part of the buckle ring, and then follow the trend The buckle is withdrawn; the present invention can not only improve the stability of the quick-release hook hook pivotally installed in the quick-release seat, but also can prevent the cable management frame from falling due to the detachment of the buckle. It has better security.

The retaining portion 3531 (refer to FIG. 12) of the retaining ring 35 then withdraws the retaining ring 35 in succession until the retaining ring 35 is completely separated from the quick release seat 31 (see FIG. 13).

Furthermore, the quick release hook 32 is further provided with a protruding pivot shaft 328 (refer to FIGS. 1 to 3). The protruding pivot shaft 328 is connected to the second pivot portion 327 of the quick release hook 32. At the same centerline, the quick release hook 32 is movably connected through the protruding pivot shaft 328 and the pivot hole 345 corresponding to the quick release cover 34 to make the pivot action of the quick release hook 32 more stable.

In summary, the present invention can be summarized to have the following enhancement effects:

1. After the combination, the latching part 322 of the quick release hook 32 is stopped by the latching part 3531 of the buckle 35, and the quick release hook 32 is pivotally arranged on the quick release seat 31, and the quick release seat 31 and a The quick release cover 34 is connected and fixed, which can improve the stability of the snap ring 32 and the quick release hook 32 pivoted by the quick release seat 31, and can also prevent the cable management frame 2 from falling due to the snap ring 35 detaching. , Which in turn has better security.

2. When disassembling and disassembling the retaining ring 35 and the quick release seat 31, it is not necessary to consider the front and rear directionality, and the front protrusion 323 or the rear protrusion 324 of the quick release hook 32 can be arbitrarily selected to make the quick release The card removing hook 32 is pivoted, so that its latching portion 323 is separated from the latching portion 3531 of the buckle 35, which is convenient to operate.

3. The component has a small volume and can meet the thin design. It is especially suitable for ultra-thin slide rails, such as server slide rails.

Therefore, the present invention does have its industrial use value, and it is applied for as an invention patent. We invite the examiner of Jun Bureau to examine it carefully and grant the patent.

However, the above are only the preferred embodiments of the present invention. When the scope of implementation of the present invention cannot be limited, all equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should still belong to the patents covered by the present invention. Within range.
