Description

Technical Field

[0001] This utility model relates to the field of metal shelf technology, specifically a height-adjustable metal plate placement and positioning mechanism. Background Technology

[0002] Metal shelves have become a popular choice for home storage and industrial storage due to their diverse materials, flexible functions, and wide applicability. Currently, there is a type of metal shelf on the market with L-shaped uprights and T-shaped locking holes on the inside of the uprights. Adjacent uprights are connected by connecting frames, and T-shaped posts that engage with the T-shaped locking holes are fixed on the connecting frames. Four connecting frames form a rectangular frame for placing metal plates. Finally, the metal plates are placed on the four connecting frames. The metal plates provide support for the items. The whole assembly is simple and flexible to use.

[0003] However, when the height of the metal plate needs to be adjusted, the metal plate needs to be removed, the four connecting brackets need to be removed one by one, and then it needs to be moved to the required height and reinstalled. The operation needs to be optimized. Based on this, a height-adjustable metal plate placement and positioning mechanism is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a height-adjustable metal plate placement and positioning mechanism in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a height-adjustable metal plate placement and positioning mechanism, comprising an L-shaped column and a metal plate. The inner sides of the two diagonal sides of the L-shaped column are respectively formed with T-shaped slots and convex sliding grooves. Multiple T-shaped slots are evenly arranged along the long side of the L-shaped column. The convex sliding grooves extend from the top of the L-shaped column to the bottom of the L-shaped column. The metal plate is located in the middle of four matrix-distributed L-shaped columns and is assembled and fixed to the L-shaped columns by positioning components.

[0006] The positioning component includes a telescopic rod, a locking block, and a connecting arm;

[0007] The bottom of the metal plate has a 7-shaped folded edge on the end face that is aligned with the T-shaped slot. The telescopic rod is located below the metal plate and passes through the 7-shaped folded edge and is fixedly connected to the snap-fit ​​round block. The telescopic rod passes through the small-diameter slot of the T-shaped slot. The snap-fit ​​round block fits against the inner cavity end face of the L-shaped column to achieve height fixation of the metal plate.

[0008] The telescopic rod and the locking block are arranged in four pairs and symmetrically distributed. The connecting arm is fixed to the outer side of the end of the telescopic rod away from the locking block. When the metal plate moves up, the locking block aligns with the large diameter slot of the T-shaped slot and the two connecting arms are pinched together to achieve the separation operation of the locking block and the T-shaped slot.

[0009] As a further improvement of this utility model, the positioning component also includes a spring and a limiting block;

[0010] The end of the telescopic rod away from the locking block protrudes to the end face of the connecting arm. The spring is distributed in the middle of the two connecting arms and sleeved on the outside of the two symmetrically distributed telescopic rods. The spring is used to provide power for the reset movement of the telescopic rod.

[0011] The limiting blocks are distributed below the metal plate and fixed to the outer wall of the telescopic rod. The limiting blocks are attached to the 7-shaped folded edge to provide a limit for the movement of the telescopic rod.

[0012] As a further embodiment of this utility model: the side of the metal plate that is aligned with the convex groove is formed with a vertical edge, and the side of the vertical edge is fixed with a convex guide post that is slidably connected to the convex groove. There are four convex guide posts, and the positions of the four convex guide posts correspond one-to-one with the convex grooves on the four L-shaped columns.

[0013] As a further improvement of this utility model: the upper surface of the connecting arm is attached to the lower surface of the metal plate, and the lower surface of the connecting arm does not protrude from the lower surface of the 7-shaped fold and the vertical edge.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The metal plate can be installed and adjusted by setting the positioning component and T-shaped slot. At the same time, the structure of the convex guide post and convex slide can maintain a stable horizontal state during the up and down movement of the No. 4 metal plate, which facilitates the alignment and insertion and separation of the locking block and the T-shaped slot. Compared with the traditional disassembly and adjustment structure, the overall operation is simpler and more convenient. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 In this embodiment of the utility model, a height-adjustable metal plate placement and positioning mechanism includes an L-shaped column 1 and a metal plate 4. The inner sides of the two diagonal sides of the L-shaped column 1 are respectively formed with T-shaped slots 2 and convex sliding grooves 3. Multiple T-shaped slots 2 are evenly arranged along the long side of the L-shaped column 1. The convex sliding grooves 3 penetrate from the top of the L-shaped column 1 to the bottom of the L-shaped column 1. The metal plate 4 is located in the middle of the four matrix-distributed L-shaped columns 1 and is assembled and fixed with the L-shaped column 1 by positioning components 6.

[0024] Positioning component 6 includes a telescopic rod 601, a locking block 602, and a connecting arm 603;

[0025] The bottom of the metal plate 4 is aligned with the end face of the T-shaped slot 2 and has a 7-shaped folded edge 5. The telescopic rod 601 is located below the metal plate 4 and passes through the 7-shaped folded edge 5 and is fixedly connected to the snap-fit ​​round block 602. The telescopic rod 601 passes through the small diameter slot of the T-shaped slot 2 and the snap-fit ​​round block 602 is attached to the inner cavity end face of the L-shaped column 1 to achieve height fixation of the metal plate 4.

[0026] The telescopic rod 601 and the locking round block 602 are provided in four pairs and symmetrically distributed. The connecting arm 603 is fixed to the outer side of the end of the telescopic rod 601 away from the locking round block 602. When the metal plate 4 moves upward, the locking round block 602 aligns with the large diameter slot of the T-shaped slot 2 and the two connecting arms 603 are pinched together to achieve the separation operation of the locking round block 602 and the T-shaped slot 2.

[0027] Positioning component 6 also includes a spring 604 and a limiting block 605;

[0028] The end of the telescopic rod 601 away from the locking block 602 protrudes to the end face of the connecting arm 603. The spring 604 is distributed in the middle of the two connecting arms 603 and sleeved on the outside of the two symmetrically distributed telescopic rods 601. The spring 604 is used to provide power for the reset movement of the telescopic rod 601.

[0029] The limiting blocks 605 are distributed below the metal plate 4 and fixed to the outer wall of the telescopic rod 601. The limiting blocks 605 are attached to the 7-shaped folded edge 5 to provide a limit for the movement of the telescopic rod 601.

[0030] In this embodiment, it should be noted that the four L-shaped columns 1 form the overall frame of the shelf. The assembly method for the metal plate 4 with the frame is as follows:

[0031] First, take a metal plate 4 and manually pinch the two connecting arms 603 to bring them closer together. The spring 604 is further compressed and contracted. At this time, the two telescopic rods 601 move closer to each other and pull the locking block 602 to move closer to the vertical part of the 7-shaped fold, that is, the locking block 602 retracts to the bottom of the metal plate 4.

[0032] Next, the metal plate 4 is moved down from above the frame composed of four L-shaped columns 1 to the middle of the frame. When the height of the metal plate 4 is determined (that is, when the snap-fit ​​block 602 is aligned with the large diameter opening of a T-shaped slot 2), the pressure on the connecting arm 603 is released. At this time, the spring 604 returns to its original position and pushes the two sets of connecting arms 603, telescopic rod 601, and snap-fit ​​block 602 away from each other. The four snap-fit ​​blocks 602 pass through the T-shaped slots 2 on the four L-shaped columns 1 and enter the inside of the L-shaped columns 1.

[0033] Then, slowly lower the metal plate 4. At this time, the telescopic rod 601 is inserted into the small diameter slot of the T-shaped slot 2 and the round block 602 is attached to the inner end face of the L-shaped column 1, thereby realizing the installation and positioning of the metal plate 4.

[0034] If you need to adjust the height of metal plate 4, simply reverse the above steps. The operation is simple and convenient.

[0035] Please refer to this carefully. Figures 1-4 The metal plate 4 has a vertical edge formed on the side that is aligned with the convex groove 3, and the side of the vertical edge is fixed with a convex guide post 7 that is slidably connected to the convex groove 3. There are four convex guide posts 7, and the positions of the four convex guide posts 7 correspond one-to-one with the convex grooves 3 on the four L-shaped columns 1.

[0036] In this embodiment: the convex guide post 7 and the convex slide groove 3 are connected to limit the horizontal and vertical movement of the metal plate 4, which facilitates the alignment and insertion and separation of the snap-fit ​​block 602 and the T-shaped slot 2.

[0037] Please refer to this carefully. Figures 4-5 The upper surface of the connecting arm 603 is in contact with the lower surface of the metal plate 4, and the lower surface of the connecting arm 603 does not protrude from the lower surface of the 7-shaped fold 5 and the vertical edge.

[0038] In this embodiment, the connecting arm 603 provides support for the metal plate 4, further enhancing the compressive strength of the metal plate 4.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
