Abstract
Description
Technical Field
[0001] The utility model particularly relates to a hidden drawer guide rail connection structure. Background Art
[0002] The drawer rails currently available on the market are generally divided into two types: two-section and three-section, with the three-section rail being the most common. The three-section rail is mainly composed of an outer rail, a middle rail, and an inner rail. For example, in a display cabinet used to display accessories, the panel of the display cabinet is usually made of transparent material. The display cabinet is provided with a mounting groove for assembling drawers, and rails are symmetrically placed at the bottom of the mounting groove. The rails are used to connect the drawers. When the drawer is pulled out, consumers can see the exposed rail parts from the panel, which affects the aesthetic performance. In addition, since the rail is directly exposed in the mounting groove, dust is easily accumulated on the rail after long-term use. Utility Model Content
[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. To this end, the utility model proposes a hidden drawer guide rail connection structure.
[0004] In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:
[0005] A hidden drawer guide rail connection structure includes a mounting groove for mounting the drawer and a guide rail body hidden below the mounting groove, wherein the mounting groove is provided with a strip groove, and the guide rail body is provided with a connecting piece, one end of the connecting piece passes through the strip groove to connect to the drawer, and pulling the drawer drives the connecting piece to move along the strip groove.
[0006] Preferably, the connecting piece has an L-shaped structure.
[0007] Preferably, the guide rail body includes a bottom rail and an outer rail slidably disposed on the bottom rail, and the connecting member is disposed on the outer rail.
[0008] Preferably, a connecting piece is slidably provided between the bottom rail and the outer rail, and balls are respectively provided on both sides of the connecting piece. Under the action of external force, the outer rail rolls with the bottom rail through the balls on the connecting piece.
[0009] Preferably, a first stopper is provided on the end of the bottom rail, and a second stopper is provided on the inner top wall of the outer rail. Pushing the outer rail drives the connecting piece to move until it abuts the first stopper, and continuing to push the outer rail causes the second stopper to abut the connecting piece.
[0010] Preferably, a buffer is provided between the bottom rail and the outer rail.
[0011] The beneficial effects of the utility model are:
[0012] Since the guide rail body is hidden under the mounting groove, when the drawer is pulled, the drawer linkage connector moves along the strip groove; when the drawer is in the pulled-out state, since the guide rail body is hidden under the mounting groove, when the consumer looks down from the panel of the display cabinet, he can only see the exposed strip groove, but not the parts of the guide rail body, thereby improving the overall aesthetics. In addition, since the guide rail body is hidden in the display cabinet under the mounting groove, dust can also be prevented from falling on the guide rail body. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] A hidden drawer rail connection structure, referring to Figure 1-Figure 3 , including a mounting groove 2 for mounting a drawer 1 and a guide rail body hidden under the mounting groove 2, the mounting groove 2 is provided with a strip groove 3, the guide rail body is provided with a connecting member 4, one end of the connecting member 4 passes through the strip groove 3 to connect to the drawer 1, and pulling the drawer 1 drives the connecting member 4 to move along the strip groove 3.
[0023] Furthermore, the connecting member 4 is in an L-shaped structure.
[0024] Furthermore, the guide rail body includes a bottom rail 51 and an outer rail 52 slidably disposed on the bottom rail 51 , and the connecting member 4 is disposed on the outer rail 52 .
[0025] Furthermore, a connecting piece 54 is slidably provided between the bottom rail 51 and the outer rail 52 , and balls 55 are respectively provided on both sides of the connecting piece 54 . Under the action of external force, the outer rail 52 rolls with the bottom rail 51 through the balls 55 on the connecting piece 54 .
[0026] Furthermore, a first stopper 511 is provided on the end of the bottom rail 51 , and a second stopper 521 is provided on the inner top wall of the outer rail 52 . Pushing the outer rail 52 drives the connecting member 54 to move to abut against the first stopper 511 , and continuing to push the outer rail 52 , the second stopper 521 abuts against the connecting member 54 .
[0027] Furthermore, a buffer is provided between the bottom rail 51 and the outer rail 52 .
[0028] The working principle of the utility model is:
[0029] The guide rail body is installed below the mounting groove 2, the lower end of the connector 4 can be welded to the outer rail 52, and the upper end of the connector 4 is connected to the drawer 1 through the strip groove 3. The mounting method of the connector 4 and the drawer 1 can be realized by bolts. Since the guide rail body is hidden below the mounting groove 2, when the drawer 1 is pulled, the drawer 1 links the connector 4 to move along the strip groove 3; when the drawer 1 is in the pulled-out state, since the guide rail body is hidden in the display cabinet 1-1 below the mounting groove 2, when the consumer looks down from the panel of the display cabinet 1-1, he can only see the exposed strip groove 3, and cannot see the parts of the guide rail body, thereby improving the overall aesthetics. In addition, since the guide rail body is hidden in the display cabinet 1-1 below the mounting groove 2, dust can also be prevented from falling on the guide rail body.
[0030] In the present application, the guide rail body can be configured as a two-section or three-section structure. Figure 3 As shown, taking a two-section guide rail as an example, the guide rail body is divided into a bottom rail 51 and an outer rail 52 slidably arranged on the bottom rail 51. The bottom rail 51 is fixedly arranged in the display cabinet. A connecting piece 54 is arranged between the outer rail 52 and the bottom rail 51. A ball 55 is rollingly arranged on the connecting piece 54. When the drawer 1 is pulled, since the drawer 1 is connected to the outer rail 52 through the connecting piece 4, pulling the drawer 1 will link the outer rail 52 to move. The outer rail 52 drives the linkage piece to achieve rolling cooperation with the bottom rail 51 through the ball 55. In order to prevent the outer rail 52 from rolling, the outer rail 52 drives the linkage piece to roll with the bottom rail 51 through the ball 55. The rail 52 slips off the bottom rail 51 during the movement. A first stopper 511 is provided on the bottom rail 51, so the outer rail 52 drives the connecting member 54 to move along the bottom rail 51 until the connecting member 54 abuts against the first stopper 511, at which time the connecting member 54 stops moving; as the drawer 1 continues to be pulled, the outer rail 52 continues to move until the second stopper 521 on the inner top wall of the outer rail 52 abuts against the connecting member 54, at which time the outer rail 52 stops moving, effectively preventing the outer rail 52 from slipping off the bottom rail 51 during the movement.
[0031] like Figure 2 As shown, taking the three-section guide rail as an example, a middle rail 50 is arranged between the outer rail 52 and the bottom rail 51. The outer rail 52 can be matched with the middle rail 50 through balls 55 and connecting parts 54. Similarly, the middle rail 50 can also be rollingly matched with the bottom rail 51 through balls and connecting parts. Figure 2 The connecting member 54 is not shown. In the above embodiment, the rolling fit ball is only one implementation method, which does not mean that only the ball can achieve rolling fit.
[0032] In the above technical solution, in order to buffer the impact force of the outer rail 52 on the side wall of the installation groove 2 during movement, or the impact force of the outer rail 52 on the bottom rail 51, a buffer can be provided between the outer rail 52 and the bottom rail 51. Since the structure and working principle of the buffer are common knowledge in the technical field, they will not be described in detail in this article. In the above structural coordination, the thickness of the bottom of the installation groove 2 is preferably set to 5 mm.
[0033] Although the utility model is described in detail with reference to the above embodiments, it is obvious to those skilled in the art through this disclosure that various changes or modifications can be made to the utility model without departing from the principle and spirit of the utility model defined by the claims. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the utility model, but the scope of protection is limited by the content of the claims.
