[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more unless otherwise explicitly specified.

[0059] Reference Figure 1 For ease of explanation, the corresponding figures use the orientations of up, down, left, right, front, and back to illustrate the relative positional relationships between the parts in this application. These should not be construed as limitations on absolute positions.

[0060] Furthermore, in this application, the first direction corresponds to the left and right directions. Here, the first direction indicates the left and right directions only for the convenience of introducing the specific embodiments of this application. There is no absolute correspondence between the first direction and the left and right directions.

[0061] The first orientation in this application is only for expressing relative positional relationships; they merely indicate approximate directions, not absolute geometric relationships.

[0062] Firstly, this application provides a guide rail 100, with reference to Figures 1 to 15 It includes a rail body 110, a pivot 120 and a latch 130, with the pivot 120 and the latch 130 located at opposite ends of the rail body 110 and on the same side surface of the rail body 110.

[0063] The rail body 110 extends along a first direction, and the pivot 120 is disposed at the end of the rail body 110. The pivot 120 includes a rotating shaft portion 121 and a limiting portion 122. The rotating shaft portion 121 is used to limit the rotation axis 12c of the rail body 110, and the limiting portion 122 is used to limit the displacement of the rail body 110 along the rotation axis 12c. The limiting portion 122 protrudes from the rotating shaft portion 121 at least in a direction perpendicular to the rotation axis 12c.

[0064] Through the above technical solution, the rotation axis 12c of the rail body 110 and the displacement of the rail body 110 along the rotation axis 12a can be restricted by the pivot 120. At the same time, the limiting part 122 protrudes from the rotating shaft part 121 at least in the direction perpendicular to the rotation axis 12c. The limiting part 122 and the rotating shaft part 121 can be used together to restrict the position of the rail body 110, thereby improving the stability of the rail body 110.

[0065] In some embodiments, reference Figure 3 The rotating shaft 121 is cylindrical in structure.

[0066] refer to Figure 3 The rotating shaft 121 is constructed as a cylinder, which can better restrict the rotation axis 12c of the rail body 110 when the rotating shaft 121 rotates.

[0067] For example, when the rotating shaft 121 is constructed as a cylinder, refer to Figure 3 The outer wall of the cylinder is constructed as a rotating body surface 12b with a rotation axis 12a perpendicular to the first direction.

[0068] In some embodiments, reference Figure 3 The cylinder has a rotation axis 12a perpendicular to a rotation surface 12b in the first direction;

[0069] The limiting part 122 is formed on the rotating surface 12b of the cylinder.

[0070] By forming the limiting part 122 onto the rotating surface 12b of the cylinder, the connection between the limiting part 122 and the rotating shaft part 121 can be made more stable.

[0071] For example, the limiting part 122 and the rotating part 121 can be integrally formed.

[0072] It should be noted that, on the projection plane of the rotation axis 12c, the projection of the limiting part 122 is located within the projection of the rotating shaft part 121. That is, along the rotation axis 12c, the size of the rotating shaft part 121 is larger than the size of the limiting part 122.

[0073] Meanwhile, in order to better operate the rotation of the rail body 110 around the rotation axis 12c, the end face of the rotating shaft part 121 and the end face of the limiting part 122 can be set coplanarly along the direction of the rotation axis 12c. This technical solution can also facilitate the molding of the knob.

[0074] In some embodiments, reference Figure 3 The limiting part 122 protrudes from the rotating shaft part 121 along the first direction.

[0075] By making the limiting part 122 protrude from the rotating shaft part 121 in the first direction, that is, after the rotating shaft part 121 rotates around the rotation axis 12c by a certain angle, the projection of the limiting part 122 and the projection of the column 200 on the projection plane along the rotation axis 12c can be overlapped, thereby realizing that the limiting part 122 restricts the displacement of the track body 110 along the rotation axis 12c.

[0076] It should be noted that the rotation axis 12c in this embodiment is perpendicular to the first direction, that is, the limiting part 122 protrudes from the rotating shaft part 121 perpendicular to the rotation axis 12c.

[0077] Based on this, the limiting part 122 can limit the displacement of the rail body 110 along the direction perpendicular to the first direction, so that the rail body 110 can be more stably restricted under the action of the limiting part 122.

[0078] For example, the number of limiting parts 122 is set to one, but it can also be set to two. When there are two limiting parts 122, both limiting parts 122 are set along the first direction and facing opposite directions, and the included angle between the two limiting parts 122 is a flat angle.

[0079] In some embodiments, reference Figure 1 and Figure 4 The guide rail 100 also includes: a latch 130.

[0080] refer to Figure 4 The latch 130 is located at the other end of the rail body 110 away from the pivot 120. The latch 130 and the pivot 120 work together to restrict the rail body 110, which can further improve the stability of the rail body 110.

[0081] refer to Figure 4 The latch 130 includes: an anti-slip part 131 and a latching part 132.

[0082] The anti-detachment part 131 can limit the displacement of the rail body 110 along the rotation axis 12c, and the locking part 132 can limit the movement of the rail body 110 around the rotation axis 12c, wherein the locking part 132 is located between the anti-detachment part 131 and the rail body 110.

[0083] The locking part 132 is connected to the rail body 110, and the anti-detachment part 131 is integrally formed with the locking part 132.

[0084] In some embodiments, along a projection plane perpendicular to the rotation axis 12c, the projection of the snap-fit ​​portion 132 is located within the projection of the anti-detachment portion 131.

[0085] By placing the projection of the latching part 132 within the projection of the anti-detachment part 131 along a projection plane perpendicular to the rotation axis 12c, the structure of the latch 130 is set more reasonably.

[0086] In some embodiments, the rotation axis 12c is collinear with the slewing axis 12a.

[0087] By setting the rotation axis 12c and the slewing axis 12a to be collinear, the rotation of the knob 120 can be made more stable, thereby achieving the effect of stable rotation of the rail body 110.

[0088] Of course, the rotation axis 12c of the rotating shaft 121 can also be non-collinear with the rotation axis 12a, making the operation more flexible.

[0089] According to a second aspect of this application, a drawer cabinet is provided, comprising: a guide rail 100 as described above; and uprights 200.

[0090] refer to Figures 6 to 15 The column 200 includes a column body 210, which is connected to the rail body 110 via a pivot 120 and a latch 130 on the rail body 110.

[0091] The column 210 has a shaft connection hole 210a for the knob 120 to pass through at a preset angle.

[0092] Among them, the column 210 has a rotating shaft wall 211 and a clearance wall 212 formed at the shaft connection hole 210a.

[0093] The rotating shaft wall 211 is adapted to the outer contour of the rotating shaft part 121 so that the pivot 120 can contact the rotating shaft part 121 both when it passes through the shaft connection hole 210a and after it passes through the shaft connection hole 210a.

[0094] The clearance wall 212 is adapted to the outer contour of the limiting part 122 so as to avoid the limiting part 122 when the knob 120 passes through the shaft connection hole 210a at a preset angle.

[0095] refer to Figure 15 The pivot wall 211 and the clearance wall 212 are continuously arranged.

[0096] The outlines of the pivot wall 211 and the clearance wall are both set to circles.

[0097] In some embodiments, reference Figure 12 The column 210 also includes a snap-fit ​​hole 210b.

[0098] After the pivot 120 passes through the pivot hole 210a at a preset angle and rotates around the rotation axis 12c, the latch 130 can move from the first position to the second position relative to the column 210 within the latch hole 210b.

[0099] When the latch 130 is in the first position relative to the column 210, the pivot 120 completes the action of passing through the pivot hole 210a and the first action of rotating around the rotation axis 12c by a certain angle.

[0100] When the latch 130 is in the second position relative to the column 210, the pivot 120 continues to rotate around the rotation axis 12c by a certain angle after the first action.

[0101] It should be noted that when the latch 130 moves from the first position to the second position, the track body 110 also rotates around the rotation axis 12c.

[0102] refer to Figure 8 and Figure 14 The shaft connection hole 210a of this application is inclined along the first direction, and the inclination angle can be set to 45°.

[0103] In some embodiments, reference Figure 15 The column 210 has a limiting wall surface 213 and a relief wall surface 214 formed at the snap-fit ​​hole 210b.

[0104] The limiting wall 213 is adapted to the outer contour of the locking part 132 so that when the button 130 is in the second position relative to the column 210, the displacement of the anti-disengagement part 131 relative to the column 210 along the rotation axis 12c can be limited.

[0105] The clearance wall 214 is adapted to the outer contour of the anti-detachment part 131 so that the locking part 132 can pass through when the button 130 is in the first position relative to the column 210.

[0106] In the embodiments of this application, if the cross-sectional area of ​​the anti-detachment part 131 is larger than the cross-sectional area of ​​the snap-fit ​​part 132, then the cross-sectional area defined by the yielding wall 214 is larger than the cross-sectional area defined by the limiting wall 213.

[0107] In some embodiments, after the guide rail 100 and the upright column 200 are connected, they form a frame 10, which can hold drawers and form a drawer cabinet for user use.

[0108] The drawer cabinet of this application is stable in use and easy to disassemble.

[0109] The installation method of the drawer slides 100 and uprights 200 of this application is as follows:

[0110] By tilting the rail body 110 so that the knob 120 can pass through the shaft connection hole 210a, and after rotating it around the rotation axis 12c by a certain angle, the latch 130 can pass through the connection hole 210b, and move from the first position to the second position relative to the main body within the connection hole 210b, thereby completing the assembly of the guide rail 100 and the column 200.

[0111] After rotating a certain angle around the rotation axis 12c, the latch 130 passes through the latching hole 210b from back to front.

[0112] In the second position, the latching part 132 of the latch 130 contacts the column body 210 of the column 200, that is, the column body 210 of the column 200 can be located in the space between the anti-detachment part 131 and the column body 210.

[0113] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
