Description

Technical Field

[0001] The present invention discloses a slide rail, belonging to the technical field of server slide rails, and specifically relates to a double unlocking mechanism for a slide rail. Background Art

[0002] Servers are usually installed in cabinets, and matching slide rails are provided in the cabinets to facilitate operations such as exporting and importing the servers relative to the cabinets for maintenance.

[0003] Self-locking mechanisms are provided on the server slide rails in the prior art. Whether the slide rails are closed or opened, the slide rails can be well braked to prevent derailment of the slide rails. However, when the slide rails need to be unlocked, for example, when the slide rails are in the open state and at this time the slide rails are in the locked stage. When it is necessary to close the slide rails, the traditional unlocking structure pulls the pull rod, so that the dial is lifted upward, and thus the locked state of the slide rails can be released. At this time, the slide rails can be pushed in to complete the closing. However, such an unlocking mechanism has certain risks. When the pull rod is pulled and the dial is lifted upward, the slide rails are in a completely free state. When the staff operates improperly, the slide rails together with the server will be pulled out, and in severe cases, the server will be damaged. Summary of the Invention

DETAILED DESCRIPTION OF THE INVENTION

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] A double-unlocking mechanism for a slide rail, comprising: a first rail assembly 100 and a second rail assembly 90;

[0029] As Figure 1 shown, the first rail assembly 100 is located inside the second rail assembly 90 and is slidably connected through a ball cage 130, and the ball cage 130 moves along with the first rail assembly 100.

[0030] In one embodiment, the present invention can set the number of sections of the slide rail according to the working occasion, and all are slidably connected relative to each other along the length direction, and an unlocking assembly 200 is provided between every two adjacent sections of the slide rail.

[0031] As Figures 2 - 5 shown, the unlocking assembly 200 includes: a first pull rod 201, a second pull rod 202 that can be linked with the first pull rod 201, and is fixedly installed on the first rail assembly 100; a first lock piece 103 and a second lock piece 104, triggered by a pull rod 105 and fixedly installed on the first rail assembly 100; a lock block 118, fixedly installed at the end of the second rail assembly 90.

[0032] In one embodiment, a plurality of first chutes 106 and first dial holes 107 are arranged along the length direction on the first pull rod 201, and the first pull rod 201 is installed on the inner side of the first rail assembly 100 through a rivet passing through the first chutes 106;

[0033] A plurality of second chutes 109 and second dial holes 112 are arranged along the length direction on the second pull rod 202, and the second pull rod 202 is installed on the inner side of the first rail assembly 100 through a rivet passing through the second chutes 109;

[0034] The first pull rod 201 and the second pull rod 202 are connected through a rivet passing through the third chute 108;

[0035] Both the first lock piece 103 and the second lock piece 104 are installed on the inner side of the first rail assembly 100 through rivets, and the pull rod 105 and the second pull rod 202 above the pull rod 105 are installed on the inner side of the first rail assembly 100 through rivets.

[0036] In one embodiment, an elastic member 113 is provided between the middle of the second pull rod 202 and the first rail assembly 100. One end of the elastic member 113 is clamped with the second pull rod 202, and the other end is clamped with the first rail assembly 100.

[0037] In one embodiment, the length of the first chute 106 is shorter than that of the second chute 109 and the third chute 108.

[0038] In one embodiment, a slideway 115 is formed at the tail of the second pull rod 202. When the second pull rod 202 is pulled, the slideway 115 drives the first lock piece 103 and the second lock piece 104 to rotate in sequence.

[0039] In one embodiment, when the slide rail is opened, the lock block 118 is located between the first lock piece 103 and the second lock piece 104; when the slide rail is closed, the lock block 118 is located at the end of the first rail assembly 100.

[0040] In one embodiment, a braking convex groove 116 extends from the tail end of the first rail assembly 100 towards the second rail assembly 90. A braking block 117 is provided on the second rail assembly 90. When the slide rail is closed, the braking block 117 is located in the braking convex groove 116.

[0041] In one embodiment, a plurality of guiding convex blocks 204 extend from the tail end of the first rail assembly 100 towards the second rail assembly 90.

[0042] In one embodiment, a convex hull 114 extends from the tail end of the first pull rod 201 towards the second rail assembly 90.

[0043] In one embodiment, a long hole 131 that penetrates and corresponds to the first dial hole and the second dial hole is provided on the first rail, allowing the operator's finger to pass from the inner side of the first rail to the outer side for more convenient operation of the pull rod.

[0044] The following is the working principle of the present invention. According to Figures 1 - 5 As shown, a plurality of second chutes along the length direction are provided on the second pull rod proposed in this application. Three second chutes are given below, namely the second chute 109, the fourth chute 110, and the fifth chute 111. These three chutes all belong to the second chute.

[0045] Working principle: First, install the slide rail, the frame 2, and the server. Fix the second rail assembly 90 in the slide rail on the frame, and install the first rail assembly 100 on the second rail assembly 90;

[0046] When the slide rail is opened, pull the first rail assembly 100. Due to the outward pulling force, the first rail assembly 100 is driven to move outward on the chute in the second rail assembly 90 through the ball cage 130. At the same time, the ball cage 130 moves with the first rail assembly 100. When the other end of the ball cage 130 contacts the limiting part in the second rail assembly 90, the ball cage 130 stops moving. When the first rail assembly 100 moves outward, at this time, the first locking piece 103 and the second locking piece 104 in the unlocking assembly 200 also move outward. When the locking block 118 in the second rail assembly 90 contacts the first locking piece 103, it will drive the first locking piece to rotate upward, so that the locking block 118 enters the locking area formed by the first locking piece 103 and the second locking piece 104. At this time, the first rail assembly 100 reaches the maximum moving distance and is braked. In addition, when there are multiple sections of rails, other rails will move outward in sequence;

[0047] When the slide rail needs to be closed, pull the first dial hole 107 on the first pull rod 201 in the unlocking assembly 200 at this time. Then the first pull rod 201 moves outward, and the moving distance is limited by the width of the first chute 106. At this time, because the first pull rod 201 moves outward, it drives the second pull rod 202 to move outward. The second pull rod 202 moves outward on the second chute 108, the third chute 109, the fourth chute 110, and the fifth chute 111. Since the width of the first chute 106 is lower than that of the second chute 108, the third chute 109, the fourth chute 110, and the fifth chute 111, when the second pull rod 202 moves outward, it only drives the first locking piece 103 to rotate upward through the outer slide way 115. At this time, due to the opening of the first lock door, the locking block 118 can move outward at this time. So when pulling the first dial hole 107, it pushes the first rail assembly 100, thus unlocking the slide rail. At this time, the first rail assembly 100 moves inward through the ball cage 130, and the locking piece disengages from the locking area. When the braking convex groove 116 at the tail of the first rail assembly 100 cooperates with the braking block 117 at the tail of the second rail assembly 90, the first rail assembly 100 reaches the maximum moving distance and is braked, thus completing the closing work of the slide rail;

[0048] When the slide rail needs to be removed, the first rail assembly 100 is pulled open to the open state at this time. At this time, the lock block 118 is located between the first lock piece 103 and the second lock piece 104. Then, the second dial hole 112 of the second pull rod 202 in the unlocking assembly 200 is pulled, and further the second pull rod 202 is pulled to move outwards on the second chute 108, the third chute 109, the fourth chute 110, and the fifth chute 111. Due to the second chute 108, the first pull rod 201 does not work at this time. While the second pull rod 202 is moving, the slideway 115 at the tail drives the first lock piece 103 and the second lock piece 104 to rotate outwards simultaneously. When the second pull rod 202 abuts against the convex protrusion 114 on the first pull rod 201, the second pull rod 202 is at the maximum pulling distance. At this time, the first lock piece 103 and the second lock piece 104 are in the open state. Then, pulling the first rail assembly 100 can complete the removal work;

[0049] In addition, when the second pull rod 202 is pushed, the first rail assembly 100 can also be pushed in to complete the closing work of the slide rail.

[0050] Obviously, the above embodiments are only examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
