Description

Technical Field

[0001] This utility model relates to the field of slide rail structure technology, and more specifically, to a track unlocking structure and cabinet. Background Technology

[0002] A drawer slide is a mechanical device that enables smooth linear reciprocating motion. It typically consists of outer, middle, and inner rails. Due to its low friction, high load-bearing capacity, and precise guidance, it is widely used in scenarios requiring flexible movement or pull-out mechanisms. For example, in server racks, drawer slides are installed between the rack and the equipment, allowing servers to slide out smoothly for maintenance or hardware replacement, preventing damage from direct dragging. In home or office settings, drawer slides ensure smooth and silent opening and closing of storage spaces. Whether it's a deep drawer in a kitchen cabinet or a multi-tiered drawer in a desk or filing cabinet, high-quality drawer slides ensure long-term use without jamming or falling off, significantly improving operational convenience and space utilization.

[0003] The inner rail is fixedly connected to the pull-out component, such as the server or drawer mentioned above. The inner rail and the middle rail are detachable. Therefore, when the pull-out component needs to be detached, the inner rail and the middle rail need to be detached. Currently, after the pull-out component is pulled out, the operator needs to move the unlocking mechanism to unlock the inner rail and the middle rail. The unlocking mechanism requires components such as springs and torsion springs for reset. Therefore, the springs and other components need to be assembled during installation, which is cumbersome. Utility Model Content

[0004] Therefore, in order to solve the problem of cumbersome installation of the unlocking structure between the inner and middle rails, this utility model provides a track unlocking structure, the specific technical solution of which is as follows: A track unlocking structure includes an unlocking plate, a locking plate, an elastic piece, and a stop block. The unlocking plate is rotatably mounted on an inner rail. The locking plate is pre-installed on the middle rail near the inner rail, and the unlocking plate has a locking groove on one side in the rotation direction for the locking plate to engage. The stop block is pre-installed on the inner rail. One end of the elastic piece is elastically and integrally connected to the unlocking plate, and the other end of the elastic piece is connected to the stop block. When the elastic piece is in its initial state, the locking plate engages in the locking groove.

[0005] By adopting the above technical solution, when it is necessary to remove the inner rail from the middle rail, the unlocking plate is rotated to make the locking plate leave the locking groove, thus unlocking the inner rail and the middle rail. At this time, the elastic piece is in an elastic state. After the unlocking plate is released, it can be elastically reset through the elastic piece. Since the elastic piece is integrally formed with the unlocking plate, only the unlocking plate needs to be assembled. Therefore, compared with the use of springs and other methods, the number of overall parts is reduced, and the assembly of the unlocking structure between the inner rail and the middle rail is improved.

[0006] Furthermore, the locking groove is located on one side of the pivot of the unlocking plate, and the elastic piece is located on the other side of the pivot of the unlocking plate. The end of the elastic piece away from the unlocking plate abuts against one side of the stop block. The direction of the elastic piece abutting against the stop block is opposite to the direction of the locking groove on one side of the unlocking plate.

[0007] Furthermore, the locking groove is formed on the downward-facing side of the unlocking plate, and the elastic piece abuts against the upward-facing side of the stop block.

[0008] Furthermore, a toggle handle is provided at the end of the unlocking plate away from the elastic sheet.

[0009] Furthermore, the unlocking plate is provided with inclined guide surfaces on both sides of the locking groove.

[0010] Furthermore, a limiting hole is provided on the unlocking plate, the limiting hole extending in the rotation direction of the unlocking plate; a limiting member is provided at the limiting hole, the limiting member passing through the limiting hole and fixed to the inner rail.

[0011] Furthermore, the limiting member is a first rivet, the head of the first rivet is located on the side of the unlocking plate away from the inner rail, and there is a gap between the head of the first rivet and the unlocking plate for the unlocking plate to rotate.

[0012] Furthermore, the pivot of the unlocking plate is a second rivet, which passes through the unlocking plate and is fixed to the inner rail. The head of the second rivet is located on the side of the unlocking plate away from the inner rail, and there is a gap between the head of the second rivet and the unlocking plate for the unlocking plate to rotate.

[0013] Furthermore, the elastic sheet is made of the same material as the unlocking plate.

[0014] Accordingly, this utility model also provides a cabinet, including the track unlocking structure described above. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0022] like Figure 1 and Figure 2As shown, a track unlocking structure in one embodiment of this utility model includes an unlocking plate 21, a locking plate 2, an elastic piece 3, and a stop block 4. The unlocking plate 21 is rotatably installed on the inner rail near the middle rail. The locking plate 2 is pre-installed on the middle rail near the inner rail. The unlocking plate 21 has a locking groove 11 on the downward side in the rotation direction for the locking plate 2 to be engaged. The stop block 4 is pre-installed on the inner rail and is integrally formed with the inner rail. One end of the elastic piece 3 is elastically and integrally connected to the unlocking plate 21, and the other end of the elastic piece 3 is connected to the stop block 4. When the elastic piece 3 is in the initial state, the locking plate 2 is engaged in the locking groove 11. The elastic piece 3 and the unlocking plate 21 are made of the same material, SUS301 0.6T, which is elastic stainless steel. Therefore, when processing the unlocking plate 21, a section is reserved to be bent into the elastic piece 3, so that the elastic piece 3 and the unlocking plate 21 are elastically and integrally connected. This reduces the number of parts, and only the unlocking plate 21 needs to be assembled to complete the assembly of the entire unlocking structure, which greatly improves the ease of assembly.

[0023] Specifically, the locking groove 11 is located on one side of the pivot of the unlocking plate 21, and the elastic piece 3 is located on the other side of the pivot of the unlocking plate 21. The end of the elastic piece 3 away from the unlocking plate 21 abuts against the side of the stop block 4. The direction of the side of the elastic piece 3 abutting against the stop block 4 is opposite to the direction of the locking groove 11 on the side of the unlocking plate 21. The locking groove 11 is located on the downward side of the unlocking plate 21, and the elastic piece 3 abuts against the upward side of the stop block 4. The end of the unlocking plate 21 away from the elastic piece 3 is provided with a toggle handle 12. Thus, the operator can drive the unlocking plate 21 to rotate by toggling the toggle handle 12 upwards, so that the locking plate 2 leaves the locking groove 11 and completes the unlocking. At this time, due to the action of the stop block 4, the elastic piece 3 is in an elastic state. After releasing the toggle handle 12, the unlocking plate 21 returns to its original position, and the unlocking operation is simple.

[0024] Furthermore, the unlocking plate 21 is provided with inclined guide surfaces 13 on both sides of the locking groove 11. Therefore, during normal use, when the inner rail is pulled, the locking plate 2 can be smoothly inserted into the locking groove 11 by the guiding action of the inclined guide surface 13 located on the side near the lever 12, so that the relative position of the middle rail and the inner rail is locked. When the inner rail needs to be retracted, the lever 12 is turned to unlock and then the inner rail is pushed to retract. When the inner rail is removed and installed, the inner rail is first inserted into the middle rail, the inner rail is slid, and the locking plate 2 can be smoothly inserted into the locking groove 11 by the guiding action of the inclined guide surface 13 on the other side, thus completing the assembly.

[0025] like Figure 1 and Figure 2As shown, a limiting hole 14 is provided on the unlocking plate 21. The limiting hole 14 is located on the side of the unlocking plate 21's rotating shaft near the locking groove 11, and extends in the rotation direction of the unlocking plate 21. A limiting component is provided at the limiting hole 14, which passes through the limiting hole 14 and is fixed to the inner rail. This can limit the unlocking plate 21 when it rotates, preventing the unlocking plate 21 from rotating too much and causing the elastic sheet 3 to fail. The limiting component is a first rivet 15, which is a stepped rivet. The head of the first rivet 15 is located on the side of the unlocking plate 21 away from the inner rail. There is a gap between the head of the first rivet 15 and the unlocking plate 21 for the unlocking plate 21 to rotate. As a commonly used fastener in the assembly of aluminum profile structures, the rivet is easy to prepare. Only by reducing the torque during installation is it possible to create a gap between the head of the rivet and the unlocking plate 21 for the unlocking plate 21 to rotate.

[0026] like Figure 1 and Figure 2 As shown, the pivot of the unlocking plate 21 is the second rivet 16, which is a stepped rivet. The second rivet 16 passes through the unlocking plate 21 and is fixed to the inner rail. The head of the second rivet 16 is located on the side of the unlocking plate 21 away from the inner rail. There is a gap between the head of the second rivet 16 and the unlocking plate 21 for the unlocking plate 21 to rotate, so that the unlocking plate 21 can rotate smoothly. The parts are easy to prepare and easy to assemble.

[0027] The implementation principle of the track unlocking structure in this application embodiment is as follows: when it is necessary to remove the inner rail from the middle rail, the toggle handle 12 is moved to make the unlocking plate 21 rotate, thereby allowing the locking plate 2 to leave the locking groove 11, thus completing the unlocking between the inner rail and the middle rail; at this time, the elastic piece 3 is in an elastic state, and after the toggle handle 12 is released, it can be elastically reset through the elastic piece 3.

[0028] This application also discloses a cabinet, which can be a power cabinet, monitoring cabinet, security cabinet, safe, server cabinet, etc. In this embodiment, the cabinet is a server cabinet, which includes the above-mentioned track unlocking structure.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
