Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of server racks, and in particular to a guide rail assembly for automatic fixing and automatic unlocking. Background Technology
[0002] Server racks commonly use guide rails for a pull-out structure. Conventional guide rails need to be fixed in both the retracted and extended states to maintain their position. This relies on two different structures for fixing and unlocking, making the overall structure of the guide rail more complex and hindering easy operation. Utility Model Content
[0003] One objective of this invention is to provide a guide rail assembly that automatically fixes and unlocks, simplifying the structure of the guide rail assembly, reducing production costs, and minimizing complex operations.
[0004] To achieve this objective, the present invention adopts the following technical solution:
[0005] An automatically fixing and unlocking guide rail assembly includes an outer guide rail, a middle guide rail, and an inner guide rail. The middle guide rail is located between the outer guide rail and the inner guide rail. A tongue is provided on the inner guide rail. An elastic rubber plug is installed on the middle guide rail. A positioning post is movably connected to the elastic rubber plug. One end of the positioning post is located inside the elastic rubber plug. An elastic element is connected between the elastic rubber plug and the positioning post. The other end of the positioning post is connected to a slanted ring. A positioning hole is provided on the outer guide rail, and the positioning post is engaged with the positioning hole.
[0006] As a preferred technical solution, both sides of the outer guide rail are bent inward to form an outer guide groove, and both sides of the middle guide rail slide inside the outer guide groove. Both sides of the middle guide rail are bent inward to form a middle guide groove, and both sides of the inner guide rail slide inside the middle guide groove.
[0007] As a preferred technical solution, the front end of the outer guide rail is integrally formed with an outer baffle, which restricts the position of the middle guide rail, and the front end of the middle guide rail is integrally formed with a middle baffle, which restricts the position of the inner guide rail.
[0008] As a preferred technical solution, both the side of the elastic plug near the inclined ring and the side of the inclined ring near the elastic plug are provided with arc-shaped edges.
[0009] As a preferred technical solution, the elastic element is a spring, which is sleeved in the middle of the positioning post. One end of the spring is connected to the end of the positioning post away from the inclined ring, and the other end of the spring is connected to the bottom of the inner cavity of the elastic rubber plug.
[0010] As a preferred technical solution, a relief groove is provided in the middle of the tongue, and the relief groove is engaged with the outer side of the positioning post.
[0011] The beneficial effects of this utility model are as follows: It provides an automatic fixing and automatic unlocking guide rail assembly. During use, the guide rail assembly uses a tongue to insert into an elastic plug to control the positioning post to disengage from the positioning hole for automatic unlocking. At the same time, when the tongue leaves the elastic plug, the positioning post can be automatically inserted into the positioning hole through an elastic element to fix the guide rail assembly. This simplifies the design structure of the guide rail, effectively reduces costs, and reduces the complexity of cabinet operation. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0021] like Figures 1 to 5As shown in this embodiment, an automatically fixing and automatically unlocking guide rail assembly includes an outer guide rail 1, a middle guide rail 2, and an inner guide rail 3. The middle guide rail 2 is located between the outer guide rail 1 and the inner guide rail 3. A tongue 4 is provided on the inner guide rail 3. An elastic rubber plug 5 is installed on the middle guide rail 2. A positioning post 6 is movably connected to the elastic rubber plug 5. One end of the positioning post 6 is located inside the elastic rubber plug 5. An elastic element is connected between the elastic rubber plug 5 and the positioning post 6. An inclined ring 7 is connected to the other end of the positioning post 6. A positioning hole 8 is provided on the outer guide rail 1. The positioning post 6 is connected to the positioning hole 8.
[0022] The outer guide rail 1, middle guide rail 2, and inner guide rail 3 are assembled together. The outer guide rail 1 slides relative to the middle guide rail 2, and the middle guide rail 2 slides relative to the inner guide rail 3. In the extended state, under the action of the elastic element, the positioning post 6 extends towards the outer guide rail 1, pulling the inclined ring 7 inward, so that the inner guide rail 3 can exit and slide on the middle guide rail 2. After the positioning post 6 extends to the position of the positioning hole 8, it fixes and engages the outer guide rail 1 and the middle guide rail 2. In the retracted state, the inner guide rail 3 slides into the middle guide rail 2, so that the tongue 4 is inserted along the position between the elastic rubber plug 5 and the inclined ring 7. The tongue 4 is locked in the positioning hole. After the inclined ring 7 is pushed open, the positioning post 6 is pulled inward and retracted. The elastic element contracts, and the outer end of the positioning post 6 disengages from the positioning hole 8. The middle guide rail 2 can retract to the end of the outer guide rail 1. The three guide rails form a retracted structure.
[0023] Both sides of the outer guide rail 1 are bent inward to form an outer guide groove 9. Both sides of the middle guide rail 2 slide inside the outer guide groove 9. Both sides of the middle guide rail 2 are bent inward to form a middle guide groove 10. Both sides of the inner guide rail 3 slide inside the middle guide groove 10. Under the structural action of the outer guide groove 9 and the middle guide groove 10, the three guide rails can merge into the same area in the contracted state.
[0024] The outer guide rail 1 has an integrally formed outer baffle 11 at its front end, which restricts the position of the middle guide rail 2. The middle guide rail 2 has an integrally formed middle baffle 12 at its front end, which restricts the position of the inner guide rail 3. In the retracted state, the middle guide rail 2 abuts against the outer baffle 11, while the inner guide rail 3 abuts against the middle baffle 12.
[0025] Both the side of the elastic plug 5 near the inclined ring 7 and the side of the inclined ring 7 near the elastic plug 5 are provided with arc-shaped edges. The arc-shaped edges are more conducive to the insertion of the tongue 4 and improve the structural mobility.
[0026] Specifically, the elastic element is a spring 13, which is sleeved in the middle of the positioning post 6. One end of the spring 13 is connected to the end of the positioning post 6 away from the inclined ring 7, and the other end of the spring 13 is connected to the bottom of the inner cavity of the elastic rubber plug 5. A relief groove 14 is provided in the middle of the tongue 4, which is engaged with the outer side of the positioning post 6. With the structure of the relief groove 14, the tongue 4 can be more easily inserted into the edge of the positioning post 6.
[0027] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles applied thereto. Within the scope of the technology disclosed in this utility model, any variations or substitutions that are easily conceived by those skilled in the art should be covered within the protection scope of this utility model.
