Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, and in particular to a slide rail retainer locking device. Background Technology

[0002] During slide rail installation, the retainers between the outer and middle rails, and between the middle and inner rails, are relatively free. When the middle or inner rail is inserted, the retainers move along with it, preventing the desired installation. Worse still, excessive force during installation of the middle or inner rail can push the ball retainer to the end of the outer or middle rail, causing it to deform and become unusable.

[0003] Currently, in existing technologies, a retainer lock is installed on the outer side of the outer rail or the outer side of the middle rail. The retainer lock has a latch, and when the retainer slides, it is pushed outward to open the retainer lock and the latch engages with the retainer. However, when the slide rail is installed on a server rack, a bracket needs to be installed on the outer front end of the outer rail and fixed to the server rack. The installation space for the retainer lock is small, and it is easy to interfere with the rack.

[0004] Therefore, it is necessary to design a retainer locking device for server bracket slide rails.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model discloses a slide rail cage locking device to solve the problem that the cage lock shifts inward due to collisions or shaking, hindering the movement of the cage and thus affecting the use of the slide rail.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A slide rail retainer locking device includes: a first rail, on which a first through hole is formed, a stop extending from the rear end of the inner side of the first through hole toward the front end, and a first groove formed on the first rail at the front end of the first through hole; a locking piece, whose front end is fixed to the inner side of the first groove, whose rear end extends into the first through hole and is provided with a boss protruding outward, and the stop engaging into the boss.

[0009] A further technical solution is that the slide rail retainer locking device further includes: a second rail, disposed inside the first rail, with a protrusion disposed outside the second rail; a retainer, slidably disposed between the first rail and the second rail, with a second through hole at the front end of the retainer and a third through hole at the rear end of the second through hole on the retainer, and the second through hole and the third through hole are not connected; an unlocking block and a locking block are disposed inside the locking piece; wherein, when the second rail is slid towards the front end, the protrusion of the second rail pushes the unlocking block open until the unlocking block is engaged in the second through hole and the locking block is engaged in the third through hole; when the second rail is slid towards the rear end, the protrusion of the second rail pushes the unlocking block open, causing the unlocking block to disengage from the second through hole and the locking block to disengage from the third through hole.

[0010] A further technical solution is that, when viewed from above, the front end of the locking block has a first straight edge, which is perpendicular to the sliding direction of the retainer, and the rear end of the locking block has a first inclined edge.

[0011] A further technical solution is that, when viewed from above, the front end of the unlocking block has a second bevel, and the rear end of the unlocking block has a third bevel.

[0012] A further technical solution is that the inner side of the unlocking block is higher than the inner side of the retainer, the inner side of the locking block is higher than the inner side of the retainer, and the inner side of the unlocking block is higher than the inner side of the locking block.

[0013] A further technical solution is that a fixing frame is provided at the front end of the inner side of the first rail, and guide posts are provided on the upper and lower sides of the rear end of the fixing frame; wherein, when the first rail slides out of the second rail at the front end, the rear end of the fixing frame abuts against the front end of the retainer, and at the same time the retainer is engaged between the guide post and the inner side of the first rail.

[0014] A further technical solution is that the front and rear ends of the protrusion are beveled, and the middle is a straight edge, with the straight edge parallel to the sliding direction of the second rail.

[0015] A further technical solution is that a rivet hole is opened on the locking piece, a rivet block is provided in the first groove, and the rivet block is pressed into the rivet hole.

[0016] A further technical solution is that the bump, locking block and unlocking block are formed by convex hull molding.

[0017] The beneficial effects of this utility model embodiment are as follows:

[0018] (I) The slide rail retainer locking device of this utility model fixes the front end of the locking piece in the first groove inside the first rail, and inserts the stop block in the first through hole into the protrusion facing outward at the rear end of the locking piece, thereby restricting the position of the locking piece, preventing it from interfering with the retainer, and ensuring that the retainer lock can slide between the first and second rails, thus improving the stability of the slide rail. At the same time, the locking piece occupies very little space on the outer side of the first rail, making it suitable for installation on server rack slide rails.

[0019] (ii) Furthermore, by sliding the second rail, the second rail drives the cage to slide, so that the cage locks with the locking piece when the second rail is pulled out, and the locking piece is pushed open when the second rail is retracted to unlock the cage and the locking piece. The structure is simple and the slide rail runs stably. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] First embodiment:

[0028] This embodiment discloses a slide rail retainer locking device.

[0029] exist Figure 1In the embodiments shown in the other figures, the direction pointed to by arrow X is the front end of the slide rail, that is, the opening direction, the opposite direction pointed to by arrow X is the rear end of the slide rail, that is, the closing direction, the direction pointed to by arrow Y is the inner side of the slide rail, and the opposite direction pointed to by arrow Y is the outer side of the slide rail.

[0030] like Figure 1 As shown, the slide rail retainer locking device includes a first rail 1 and a locking piece 3.

[0031] A first through hole 11 is formed on the first track 1, and a stop block 12 extends from the rear end of the inner side of the first through hole 11 toward the front end. A first groove 14 is formed on the first track 1 at the front end of the first through hole 11.

[0032] The front end of the locking piece 3 is fixed to the inner side of the first groove 14, and the rear end extends into the first through hole 11 and is provided with a boss 34 protruding outward. The stop block 12 is inserted into the boss 34.

[0033] For example, a rivet hole 31 is provided on the locking piece 3, and a rivet block 13 is provided inside the first groove 14. The rivet block 13 is pressed into the rivet hole 31 to realize the rivet connection between the locking piece 3 and the first rail 1.

[0034] In this embodiment, by fixing the front end of the locking piece 3 into the first groove 14 inside the first rail 1, and inserting the stop block 12 in the first through hole 11 into the protrusion 34 protruding outward from the rear end of the locking piece 3, the position of the locking piece 3 is restricted, preventing it from interfering with the retainer 4. This ensures that the retainer 4 can slide between the first rail 1 and the second rail 2, improving the stability of the slide rail. Simultaneously, the locking piece 3 occupies very little space on the outer side of the first rail 1, making it suitable for installation on server rack slide rails.

[0035] Second embodiment:

[0036] Based on the first embodiment, the second embodiment further optimizes and refines the slide rail cage locking device of the first embodiment.

[0037] like Figures 2-4 As shown, the slide rail retainer locking device also includes a second rail 2, a retainer 4, and a locking piece 3.

[0038] The second rail 2 is disposed inside the first rail 1, and a protrusion 21 is disposed on the outer side of the second rail 2. For example, the front and rear ends of the protrusion 21 are beveled to reduce the friction when the protrusion 21 pushes the locking block 33, and the middle has a straight edge parallel to the sliding direction of the second rail 2, which allows the locking block 33 sufficient time to enter or disengage from the third through hole 42. The beveled edge can be a straight surface or an arc surface, as long as it can push the locking block 33 outward.

[0039] The retainer 4 is slidably disposed between the first rail 1 and the second rail 2. A second through hole 41 is opened at the front end of the retainer 4, and a third through hole 42 is opened at the rear end of the second through hole 41 on the retainer 4. The second through hole 41 and the third through hole 42 are not connected.

[0040] The inner side of the locking piece 3 is provided with an unlocking block 32 and a locking block 33.

[0041] like Figure 3 and Figure 4 As shown, the second rail 2 slides towards the front end, and the protrusion 21 of the second rail 2 pushes the unlocking block 32 until the unlocking block 32 engages with the second through hole 41, and the locking block 33 engages with the third through hole 42. For example, when viewed from above, the locking block 33 has a first straight edge 332 at its front end, which is perpendicular to the sliding direction of the retainer 4, preventing the retainer 4 from sliding rearward relative to the locking block 3. The locking block 33 has a first inclined edge 331 at its rear end, reducing friction with the retainer 4. The first inclined edge 331 can be a straight edge or an arc edge.

[0042] like Figure 4 As shown, the second rail 2 slides towards the rear end, and the protrusion 21 of the second rail 2 pushes the unlocking block 32 away, causing the unlocking block 32 to disengage from the second through hole 41, and the locking block 33 to disengage from the third through hole 42. For example, the inner side of the unlocking block 32 is higher than the inner side of the retainer 4, and the inner side of the locking block 33 is higher than the inner side of the retainer 4, ensuring that there is a sufficiently large displacement at the unlocking block 32 so that the locking block 33 can disengage from the third through hole 42.

[0043] like Figure 2 As shown, further, when viewed from above, the front end of the unlocking block 32 has a second bevel 321 and the rear end of the unlocking block 32 has a third bevel 322, so that the second rail 2 can push the unlocking block 32 and the locking piece 3 apart and slide in and out of the first rail 1.

[0044] If the protrusion 21, locking block 33, and unlocking block 32 are formed using a flanged forming process, the contact surfaces of the protrusion 21, locking block 33, and unlocking block 32 are cut surfaces, resulting in deeper friction marks between the protrusion 21 and unlocking block 32, as well as between the retainer 4 and locking block 33. Preferably, the protrusion 21, locking block 33, and unlocking block 32 are formed using a convex-hull forming method, so that the contact surfaces of the protrusion 21, unlocking block 32, and locking block 33 are the surface of the raw material during operation, which can significantly reduce the friction marks between the protrusion 21 and unlocking block 32, as well as between the retainer 4 and locking block 33.

[0045] like Figure 1As shown, a fixing frame 5 is further provided on the inner front end of the first rail 1, and guide posts 51 are provided on the upper and lower sides of the rear end of the fixing frame 5. When the first rail 1 slides out to the front end of the second rail 2, the rear end of the fixing frame 5 abuts against the front end of the retainer 4 to restrict the retainer 4 from sliding forward. At the same time, the retainer 4 is engaged between the guide posts 51 and the inner side of the first rail 1, ensuring that the retainer 4 is correctly positioned when blocked and will not slide out from the inner side of the guide posts 51. This avoids the need for additional steps in disassembling and assembling the retainer 4, reduces the risk of deformation and damage to the retainer 4, and improves the efficiency of installation and disassembly.

[0046] In this embodiment, the second rail 2 is slid towards the front end, and the protrusion 21 of the second rail 2 pushes the unlocking block 32 until the unlocking block 32 is engaged in the second through hole 41, the locking block 33 is engaged in the third through hole 42, and the locking piece 3 returns to its original shape under its own elastic force, so as to realize the locking retainer 4.

[0047] Slide the second rail 2 toward the rear end. The protrusion 21 of the second rail 2 pushes the unlocking block 32 away. At this time, the unlocking block 32 disengages from the second through hole 41, the locking block 33 disengages from the third through hole 42, and the retainer 4 is in a free state and slides together with the second rail 2 to unlock the retainer 4. When the protrusion 21 disengages from the unlocking block 32, the locking piece 3 returns to its original state under its own elastic force.

[0048] The slide rail retainer locking device of this embodiment achieves the following: when the second rail 2 is pulled out, the retainer 4 is locked with the locking piece 3; when the second rail 2 is retracted, the locking piece 3 is pushed open to unlock the retainer 4 from the locking piece 3. The structure is simple and the slide rail operation is stable.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
