Description

Technical Field

[0001] The utility model relates to a slide rail device, in particular to a safety slide rail device. Background Art

[0002] The current design is that when the user installs the slide rail to the rack, the slide rail will change from a closed state to an extended state because it is not restrained during the installation process. At this time, the user's hands or feet may be scratched during the installation. Therefore, there are still concerns about the safety of installing the slide rail. Utility Model Content

[0003] The purpose of the utility model is to provide a safety slide rail device which can solve at least one of the above problems.

[0004] The utility model provides a safety slide rail device, comprising an outer rail unit, the outer rail unit comprising an outer rail and a safety stopper, the outer rail having a sliding surface, the safety stopper being arranged on the sliding surface; and a middle rail, movably arranged on the sliding surface of the outer rail, the middle rail having a middle outer surface facing the outer rail; wherein the safety stopper abuts against the middle outer surface to prevent the middle rail from sliding relative to the outer rail.

[0005] In some implementations, the safety stopper has a protrusion abutting against the middle and outer surfaces.

[0006] In some implementations, the safety stopper further has a main body and an elastic arm, the main body forms an opening, the elastic arm extends from the main body toward the opening, and the protrusion is formed on the elastic arm.

[0007] In some implementations, the safety stopper is made of metal or plastic.

[0008] In some implementations, the protrusion is an arc-shaped convex surface.

[0009] In some implementations, the middle rail forms a slot for the protrusion to extend into.

[0010] The utility model has at least the following technical effects: by the safety stopper abutting against the BCPI-240313 Page 2 / 4

[0011] The middle rail is prevented from sliding relative to the outer rail. When the user installs the safety slide rail device on a server cabinet, the middle rail will not slide relative to the outer rail to cause the risk of scratching the user's hands and feet, thereby increasing safety.

[0018] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0019] In the description of the present invention, it should be understood that the descriptions involving orientation, such as up, down, front, back, left, right, etc., the orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] In the description of the present utility model, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed" etc. are understood to exclude the number itself, and "above", "below", "within" etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0021] In the description of this utility model, unless otherwise expressly defined, setting, installing, connecting, etc. BCPI-240313 Page 3 / 4

[0022] The terms should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0023] See also Figure 1 and Figure 2An embodiment of the safety rail device of the utility model is suitable for installation in a server cabinet (not shown). The safety rail device comprises an outer rail unit 1, a middle rail 2 and an inner rail 3.

[0024] See also Figures 2 to 4 The outer rail unit 1 includes an outer rail 11 and a safety stopper 12. The outer rail 11 has a sliding surface 111 and a mounting surface 112 opposite to the sliding surface 111 and facing the server cabinet (not shown). The safety stopper 12 is fixed to the sliding surface 111 by two fixing members 13, and has a main body 121, an elastic arm 122 and a protrusion 123. The main body 121 forms an opening 121a, and the elastic arm 122 extends from the main body 121 toward the opening 121a. The protrusion 123 is formed on the elastic arm 122 and abuts against the middle rail 2. Specifically, the protrusion 123 is an arc-shaped convex surface, and the material of the safety stopper 12 is metal or plastic, but it is not limited thereto.

[0025] The middle rail 2 is movably disposed on the sliding surface 111 of the outer rail 11. The middle rail 2 has a middle outer surface 21 facing the outer rail 11 and a middle inner surface 22 facing the inner rail 3 opposite to the middle outer surface 21. The inner rail 3 is movably disposed on the middle rail 2. The middle rail 2 forms a slot 23 for the protrusion 123 to extend into. The protrusion 123 of the safety stopper 12 abuts against the middle outer surface 21 and penetrates into the slot 23 to prevent the middle rail 2 from sliding relative to the outer rail 11. In this way, when a user installs the safety slide rail device on the server cabinet (not shown), the middle rail 2 will not slide out relative to the outer rail 11 and cause the risk of scratching the user's hands and feet, thereby increasing the safety of the user during installation. The user needs to directly apply a pulling force to the middle rail 2 and the inner rail 3 to overcome the maximum static friction between the protrusion 123 and the middle outer surface 21 and the slot 23, so that the middle rail 2 and the inner rail 3 can be pulled out relative to the outer rail 11. Figure 5 shown.

[0026] In summary, the safety slide rail device of the present invention prevents the middle rail 2 from sliding relative to the outer rail 11 by means of the safety stopper 12 abutting against the middle outer surface 21. When the user installs the safety slide rail device on the server cabinet, the middle rail 2 will not slide relative to the outer rail 11 and cause the risk of scratching the user's hands and feet. This can increase safety and truly achieve the purpose of the present invention.
