Description

Technical Field

[0001] The utility model relates to the technical field of guide rail structures, in particular to a synchronous guiding device suitable for pulling out guide rails. Background Art

[0002] In the field of furniture drawer rails, there are various types of rail structures, generally including upper rails, middle rails and lower rails that are slidably connected to each other, and ball rack accessories for guiding the sliding are set between the upper rail and the middle rail, and between the middle rail and the lower rail, so that the pulling and pulling of the rails can remain smooth. However, due to the phenomenon of slippage and other phenomena of the roller groups of the ball rack, the middle rail does not move when the upper rail moves, until the upper rail moves to the limit position and collides with the middle rail, so that the middle rail and the upper rail move synchronously. In this way, there will undoubtedly be a collision sound and a sense of frustration when pulling and pulling, and the user experience is poor.

[0003] To this end, some manufacturers now add synchronization devices between the upper rail, the middle rail and the lower rail in order to achieve the function of synchronous pulling, so as to ensure the synchronous movement of the middle rail and the upper rail. However, the existing synchronization device has a complex structure and assembly difficulty, which not only leads to abnormal problems during actual use, but also has high manufacturing costs.

[0006] Furthermore, the middle rail includes an integrally formed horizontal portion and two vertical portions respectively distributed vertically at both ends of the horizontal portion, wherein the synchronous guiding device is arranged on the outer side surface of any vertical portion.

[0007] Furthermore, the synchronous guide device is correspondingly installed on the vertical portion adjacent to the side of the lower rail, wherein the first cable segment and the second cable segment are directly connected to the upper rail and the lower rail respectively.

DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of the present invention, the present invention is described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0020] See attached Figure 1-6 As shown, in this embodiment, a synchronous guiding device suitable for pulling out a guide rail comprises an upper rail 1, a middle rail 2 and a lower rail 3 which are slidably connected in sequence, wherein the upper rail 1 is used to connect with a drawer body of the furniture, and the lower rail 3 is used to connect with a cabinet body of the furniture, thereby, the upper rail 1 and the middle rail 2 can be pulled and pulled relative to the lower rail 3 to realize the opening and closing action of the drawer body.

[0021] In this embodiment, a synchronous guide device 4 is also included on the middle rail 2, and the synchronous guide device 4 is used to achieve the upper rail 1 and the middle rail 2 to maintain a consistent movement amount during the pulling. Specifically, the synchronous guide device 4 includes two synchronous rollers 41 arranged in sequence along the pulling direction and pivoted on the middle rail 2, and a synchronous cable 42 sequentially wound between each synchronous roller 41, and the synchronous cable 42 is separated by the two synchronous rollers 41 to form a first cable segment 421 and a second cable segment 422 with opposite moving directions, that is, as shown in the figure, the first cable segment 421 and the second cable segment 422 of the synchronous cable 42 of this embodiment are between the two synchronous rollers 41, wherein the position above the synchronous roller 41 is the first cable segment 421, and the position above the synchronous roller 41 is the second cable segment 422.

[0022] Furthermore, since the positions of the two synchronous rollers 41 are fixed, the lengths of the first cable segment 421 and the second cable segment 422 are also fixed values, wherein the lengths of the first cable segment 421 and the second cable segment 422 can be determined by the actual movement of the upper rail 1 and the middle rail 2, that is: the longer the movement of the upper rail 1 and the middle rail 2, the longer the corresponding lengths of the first cable segment 421 and the second cable segment 422; conversely, the shorter the movement of the upper rail 1 and the middle rail 2, the shorter the lengths of the first cable segment 421 and the second cable segment 422.

[0023] In this embodiment, the first cable segment 421 and the second cable segment 422 are directly and / or indirectly connected to the upper rail 1 and the lower rail 3, respectively. For the convenience of explanation, the direct connection and / or indirect connection are further described below in conjunction with the specific implementation. Specifically, the middle rail 2 includes an integrally formed horizontal portion 21 and two vertical portions 22 respectively distributed vertically at both ends of the horizontal portion 21, and the lower rail 3 includes an integrally formed vertical side and a horizontal side horizontally distributed at the lower end of the vertical side. At this time, the synchronous guide device 4 is arranged on the outer side surface of any vertical portion.

[0024] Implementation method 1: See attached Figure 1-3 As shown, the synchronous guide device 4 is correspondingly installed on the vertical portion 22 adjacent to the side of the lower rail 3, that is, the synchronous guide device 4 at this time is correspondingly located between the side of the lower rail 3 and the vertical portion 22 of the middle rail 2. Secondly, the first cable segment 421 and the second cable segment 422 are directly connected to the upper rail 1 and the lower rail 3 respectively. Specifically, the upper rail 1 is provided with an upper connecting block 5 for connecting with the first cable segment 421 on the side adjacent to the side of the lower rail 3 (the upper connecting block 5 can be a bending structure integrally formed on the upper rail 1, or a split structure fixed by welding, screws, etc., which is not specifically limited here). The horizontal side of the lower rail 3 is provided with a lower connecting block 6 for connecting with the second cable segment 422 (the lower connecting block 6 can be a bending structure integrally formed on the upper rail 1, or a split structure fixed by welding, screws, etc., which is not specifically limited here).

[0025] Implementation method 2: See attached Figure 4-6 As shown, the synchronous guide device 4 is correspondingly installed on the vertical portion of the side away from the side of the lower rail 3, that is, the synchronous guide device 4 at this time is correspondingly located at the peripheral position of the middle rail 2. Secondly, the first cable segment 421 and the second cable segment 422 are directly connected to the upper rail 1 and the lower rail 3 respectively. Specifically, the upper rail 1 is provided with an upper connecting block 5 for connecting with the first cable segment 421 on the side away from the side of the lower rail 3 (the upper connecting block 5 can be a bending structure integrally formed on the upper rail 1, or a split structure fixed by welding, screws, etc., which is not specifically limited here), thereby realizing the direct connection between the first cable segment 421 and the upper rail 1. The second cable segment 422 is indirectly connected to the lower rail 3 by means of the extended connecting piece 7 pre-leaded out from the lower rail 3 (the extended connecting piece 7 can effectively solve the problem of insufficient width of the cross section of the lower rail 3, and the extended connecting piece 7 can be fixed to the cross section of the lower rail 3 by welding, screws or other fixing methods, so that the end of the extended connecting piece 7 can be extended and led out to the position where the second cable segment 422 is located for connection), thereby realizing the indirect connection between the second cable segment 422 and the lower rail 3.

[0026] In summary, both implementation modes one and two play a role in synchronously guiding the middle rail 2 and the upper rail 1 during the pulling and pulling process, and the specific working principle is as follows: during the pulling and pulling action, the drawer body drives the upper rail 1 to move, and since the upper connecting piece is connected to the first cable segment 421 of the synchronization cable 42, the upper rail 1 correspondingly drives the synchronization cable 42 to move in a circle around the synchronization roller; secondly, since the second cable segment 422 of the synchronization cable 42 is connected to the lower connecting piece or the extended connecting piece 7 of the lower rail 3, and since the lower rail 3 is fixed, the middle rail 2 is driven by the second cable segment 422 to keep moving synchronously with the lower rail 3 and the upper rail 1 in the same direction.

[0027] In this embodiment, the synchronous roller 41 is pivotally connected to the middle rail 2 via a preset rotating shaft arranged perpendicular to the pulling direction.

[0028] In summary, the function of the synchronous guide device 4 for pulling out the guide rail can ensure the synchronization of the upper rail 1 and the lower rail 3 during the drawing and pulling process of the drawer. According to actual needs and different furniture structures, a suitable implementation method can be selected for installation. The application of the synchronous guide device 4 can not only improve the service life of the drawer, but also improve the smoothness of opening and closing the drawer, meeting the consumer's demand for furniture use experience. In addition, the synchronous guide device 4 has a simple structure, is easy to install, and is easy to maintain, and has broad application prospects.
