If there is a description of "first", "second", etc., it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.
[0035] In the description of the present invention, unless otherwise clearly defined, words such as “setting”, “installation”, and “connection” should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention based on the specific content of the technical solution.
[0036] Drawer: usually refers to a pull-out box for storing items. For example, in structure, a drawer is a semi-enclosed container with an open top. In the present embodiment, the drawer may refer to a "pull-out box" in the popular sense, or may refer to a "drawer-like" container, such as a pull-out basket-shaped container or a pull-out basket-shaped container with a top cover.
[0037] Shelf: refers to a plate-like object that can be used to carry items. For example, in terms of structure, a shelf can be a flat plate-like structure as a whole, or it can be a non-closed structure with a straight main body and bent at both ends.
[0038] In the related art, the guide rails used to install drawers or shelves are usually in the form of straight strips, which play a guiding and bearing role for the drawers or shelves. However, during use, for example, when pulling out a drawer, the drawer is easily completely separated from the guide rail due to excessive pulling force, causing the drawer to fall, causing the items in the drawer to scatter on the ground. Similarly, the shelves are easily separated from the guide rails during use, causing the items to scatter. In order to solve this problem, a corresponding limiting structure is usually provided on the guide rail. However, due to the different structures of the drawers and shelves, the limiting structures on the guide rails are mostly not universal, resulting in the guide rails being only suitable for installing drawers or shelves once they are finalized at the factory stage, and cannot be adjusted according to actual application requirements, which is inconvenient to use. To this end, the present embodiment provides a guide rail bracket, a guide rail assembly structure, a drawer matching structure and a trolley, which are compatible with the installation of drawers and shelves and improve the flexibility of use.
[0039] Please refer to Figure 1 , Figure 2 and Figure 3 The present embodiment discloses a guide rail bracket 100, comprising a support plate 110, a drawer guide rail 120 and a shelf guide rail 130. The length of the support plate 110 extends along a first direction, wherein the first direction of the present embodiment indicates a front-to-back direction. Please refer to Figure 1 and Figure 3 The support plate 110 has a first side surface and a second side surface, and the first side surface and the second side surface are distributed on the right side and the left side. The first side surface of the support plate 110 is provided with a plurality of first connection portions 111 whose positions are centrally symmetrically distributed, wherein the first connection portions 111 may be protrusions or recessed holes. For specific application examples, reference may be made to the guide rail assembly structure embodiment below, which will not be described in detail here. The number of the first connection portions 111 may be four, and the four first connection portions 111 are distributed at the four corners of the support plate 110; the number of the first connection portions 111 may be two, and the two first connection portions 111 are distributed at the two diagonal portions of the support plate 110, or are distributed on the center line of the support plate 110.
[0040] Please refer to Figure 1 , Figure 4 and Figure 5 The drawer guide 120 is disposed on the second side of the support plate 110, and the length of the drawer guide 120 extends along the first direction. At least one end of the drawer guide 120 is provided with a first limit block 121, and the first limit block 121 is used to limit the drawer 10 carried on the drawer guide 120 to prevent the drawer 10 from completely separating from the drawer guide 120 during the pulling process. For example, please refer to Figure 5For a drawer 10 that can be pulled in the front and rear directions, the first limit block 121 is set at the front end of the drawer guide rail 120, and cooperates with the limit portion on the drawer 10 to stop and limit; when in use, the guide rail bracket 100 is usually used in pairs, so that the drawer 10 can be supported by the paired drawer guide rails 120. In order to improve the versatility of the guide rail bracket 100, the first limit blocks 121 are set at both ends of the drawer guide rail 120 in the first direction. In this way, the guide rail bracket 100 on the left and right sides of the drawer 10 can be used, reducing the difference between the guide rail bracket 100 on the left and right sides of the drawer 10, which is conducive to improving the versatility of the guide rail bracket 100. It should be conceivable that the first limit block 121 can be a convex structure, and the drawer 10 is adaptively provided with a matching concave or convex portion to stop and limit. Exemplarily, the first limit block 121 is a first protrusion set on the drawer guide 120, and a first groove (not shown) is set at the position on the drawer 10 that abuts the drawer guide 120. When the drawer 10 is carried on the drawer guide 120, the first protrusion on the drawer guide 120 can be embedded in the first groove. In this way, the drawer 10 can be guided by the cooperation of the first protrusion and the first groove during the process of being pushed in or pulled out along the drawer guide 120, and when the drawer 10 is pulled out to a preset position, the end of the first groove of the drawer 10 is stopped due to abutting against the first protrusion of the drawer guide 120, thereby preventing the drawer 10 from completely disengaging from the drawer guide 120 too easily.
[0041] Please refer to Figure 2 , the layer guide 130 is arranged on the second side of the support plate 110 and is located on one side of the drawer guide 120, and a sliding limit space 131 is formed between the layer guide 130 and the drawer guide 120. For example, when the drawer 10 is pushed into the sliding limit space 131 along the drawer guide 120, the drawer guide 120 can lower limit and guide the drawer 10, and the layer guide 130 can upper limit the drawer 10; when the drawer 10 is pulled out of the sliding limit space 131, although the first limit block 121 can prevent the drawer 10 from completely disengaging from the drawer guide 120 too easily, since most of the drawer 10 has lost the drawer guide The drawer 10 is supported by the rail 120, and the front end of the drawer 10 sinks and the rear end tilts due to the imbalance of the center of gravity in the front-to-back direction, which may easily cause the drawer 10 to flip over and fall. The shelf guide 130 can limit the drawer 10, that is, limit the activity space of the drawer 10 in the up and down directions of the sliding limit space 131, thereby reducing the tilting amplitude of the rear end of the drawer 10 and preventing the drawer 10 from flipping over and falling. The length of the shelf guide 130 extends along the first direction, and the two ends of the shelf guide 130 are provided with a second limit block 132 to form a shelf limit space. For example, the second limit block 132 can be a convex structure or a hook structure. Please refer to Figure 2 , Fig.10 and Fig.11When the shelf 20 needs to be installed, the guide bracket 100 is rotated 180° to make the shelf guide 130 under the drawer guide 120. In this way, the shelf 20 can be inserted into the shelf guide 130 and installed in the shelf limiting space. The second limiting blocks 132 at both ends of the shelf guide 130 can reduce the activity space of the shelf 20 in the front and rear directions to prevent the shelf 20 from shaking or detaching from the shelf guide 130, thereby improving stability during use.
[0042] A first limit block 121 is provided on the drawer guide 120 of the present embodiment to prevent the drawer 10 from being too easily detached, and a second limit block 132 is provided on the layer guide 130 to prevent the layer 20 from being too easily detached. The drawer guide 120 and the layer guide 130 are integrated on the support plate 110, and a plurality of first connecting portions 111 are provided on the support plate 110 and are centrally symmetrically distributed. When in use, the drawer guide 120 or the layer guide 130 can be selected according to actual application requirements, so as to be compatible with the installation of the drawer 10 and the layer 20, which is conducive to improving the flexibility of use.
[0043] According to the different limiting structures on the drawer 10, the structure of the drawer guide rail 120 can also be adaptively adjusted. Figure 4 , Figure 6 and Figure 7 , the first side of the drawer guide 120 is located in the sliding limit space 131, and a first avoidance recess 122 is provided on the first side of the drawer guide 120 and adjacent to the first limit block 121. A protruding structure, such as a second protrusion 11, is provided at the position of the drawer 10 abutting against the drawer guide 120. When the drawer 10 is pulled out to the preset position, the second protrusion 11 on the drawer 10 is embedded in the first avoidance recess 122, and the drawer 10 is stopped because the second protrusion 11 abuts against the first limit block 121, thereby preventing the drawer 10 from being over-pulled out and completely detached from the drawer guide 120. It is worth noting that the first avoidance recess 122 is provided on the adjacent side of the first limit block 121, so that the first limit block 121 can be more protruding relative to the drawer guide 120, which is conducive to abutting against the second protrusion 11 of the drawer 10.
[0044] Please continue to refer to Figure 4 , Figure 6 and Figure 7A first guide surface 123 is provided on the first side of the drawer guide rail 120 and in the first avoidance recess 122, and the first guide surface 123 faces the first stop block 121. For example, since the drawer 10 needs to be pushed and pulled along the drawer guide rail 120, when the second stop block 132 of the drawer 10 is embedded in the first avoidance recess 122 and the drawer 10 needs to be pushed in, the first guide surface 123 can play a guiding role, so that the second protrusion 11 of the drawer 10 can be separated from the first avoidance recess 122. It should be noted that a portion of the drawer guide 120 is used to set the first avoidance recess 122, and the remaining portion of the drawer guide 120 is used as a drawer bearing position 125 that supports the drawer 10. In order to facilitate guiding the second protrusion 11 to disengage from the first avoidance recess 122 through the first guide surface 123 when pushing the drawer 10, the first guide surface 123 is designed to be an inclined surface, and the first end of the inclined surface is connected to the drawer bearing position 125 of the drawer guide 120, and the second end of the inclined surface is adjacent to the first limit block 121, and the relative height of the second end of the inclined surface in the up and down direction is lower than the first end of the inclined surface, so that the first guide surface 123 faces the side of the first limit block 121, so that the guiding effect can be achieved in the process of pushing the drawer 10. Correspondingly, the second protrusion 11 of the drawer 10 can be provided with a guiding inclined surface or a guiding arc surface to cooperate with the first guide surface 123 to achieve common guiding.
[0045] As described above, the first side of the drawer guide 120 and the position adjacent to the first avoidance recess 122 is used as the drawer bearing position 125. In order to guide the second protrusion 11 of the drawer 10, a second guide surface 124 is provided between the drawer bearing position 125 and the first avoidance recess 122. The second guide surface 124 makes the side wall of the first avoidance recess 122 present an inclined structure, thereby playing a guiding role. In addition, the first guide surface 123 is an inclined structure provided at the bottom of the first avoidance recess 122. The first guide surface 123 and the second guide surface 124 are provided at the same time. On the basis of guiding the second protrusion 11 of the drawer 10, the first guide surface 123 can have a higher degree of design freedom. For example, through the secondary guiding cooperation of the first guide surface 123 and the second guide surface 124, the inclination angle of the first guide surface 123 or the sinking depth relative to the bearing surface on the drawer guide 120 can be designed according to actual application requirements to adapt to different thicknesses of the drawer guide 120.
[0046] Please refer to Figure 1, the first side of the drawer guide rail 120 is located in the sliding limit space 131, and the middle part of the first side of the drawer guide rail 120 is used as the drawer bearing position 125. The two sides of the drawer bearing position 125 are provided with a mirror-symmetrical first avoidance recess 122, wherein the structure of the first avoidance recess 122 can refer to the above, for example, a first guide surface 123 and a second guide surface 124 are provided in the first avoidance recess 122, which will not be repeated here. By providing a mirror-symmetrical first avoidance recess 122, in addition to improving the aesthetics of the guide rail bracket 100, the symmetrical use of the guide rail bracket 100 can also be achieved. For example, the guide rail bracket 100 can be used to support the left or right side of the drawer 10, without the need to customize the left and right sides of the drawer 10 respectively, and has strong applicability, which is conducive to reducing the types of materials during assembly, facilitating material management and saving material and management costs. It should be conceived that in order to achieve a mirror-symmetrical structure, a first limit block 121 is provided at both ends of the drawer guide rail 120.
[0047] Please refer to Figure 1 and Figure 2 The first side of the layer guide rail 130 is located in the sliding limit space 131, and the first side of the layer guide rail 130 is provided with a second avoidance recess 133 adapted to the drawer bearing position 125, so that the overall structure of the layer guide rail 130 and the drawer guide rail 120 is consistent, which is conducive to improving the aesthetics. It should be noted that the two sides of the layer guide rail 130 and located at the second avoidance recess 133 are used as layer bearing positions 134. When the layer 20 is placed on the layer guide rail 130, the layer 20 abuts against the layer bearing position 134 of the layer guide rail 130, and the second avoidance recess 133 can also play a role in avoiding the layer 20, making it more convenient to take and put the layer 20.
[0048] In some application examples, at least one of the second side of the drawer rail 120 and the second side of the shelf rail 130 can be used as a bearing surface. Figure 1 and Figure 2 , the second side of the drawer guide rail 120 (such as Figure 2 E2) and the second side of the deck guide rail 130 (as shown in FIG. Figure 1 When the guide rail bracket 100 is installed on the left and right sides of the drawer 10 to support the drawer 10, the second side of the shelf guide rail 130 faces upward, and can also be used as a bearing surface, for example, to support the shelf 20 or other objects. Although the shelf guide rail 130 is provided with a second limit block 132 to improve the reliability of the installation of the shelf 20, in some application scenarios, the user also hopes to facilitate the pulling out of the shelf 20. In this case, the shelf 20 can be placed on the second side of the shelf guide rail 130, so that the drawer 10 and the shelf 20 can be installed at the same time. Similarly, if Figure 2As shown, when the guide rail bracket 100 is rotated 180° so that the shelf guide 130 is located below the drawer guide 120, the shelf 20 can be placed on the shelf guide 130, and the second side of the drawer guide 120 faces upward, which can also be used to support the shelf 20 to achieve different placement intervals of the shelf 20.
[0049] Please refer to Figure 8 and Fig. 9 The present embodiment also provides a guide rail assembly structure, including a connector 200 and the guide rail bracket 100 described above, wherein the connector 200 is provided with a plurality of second connecting portions 210, and the guide rail bracket 100 and the connector 200 are detachably connected through the first connecting portion 111 and the second connecting portion 210. The connector 200 is used to install one or more guide rail brackets 100, and the structure of the guide rail bracket 100 can be referred to above, and will not be repeated here. Exemplarily, the first connecting portion 111 can be a hook structure, and the second connecting portion 210 can be a hook hole provided on the connector 200, and the hook structure can be inserted into the hook hole for hanging, so as to realize a convenient and detachable connection between the guide rail bracket 100 and the connector 200. Of course, the first connecting portion 111 can be a hook hole provided on the support plate 110, and the second connecting portion 210 can be a hook structure, and through the cooperation of the hook hole and the hook structure, a convenient and detachable connection between the guide rail bracket 100 and the connector 200 can be realized. For example, the first connection part 111 is a joint ball structure, and the second connection part 210 is a matching spherical crown-shaped recessed hole. The joint ball structure is inserted into the spherical crown-shaped recessed hole for clamping, which can realize a convenient detachable connection between the guide rail bracket 100 and the connection part.
