Description

Technical Field

[0001] The present application relates to the technical field of shelf columns, and in particular to a stable docking device for warehouse shelf columns. Background Art

[0002] Shelves are a type of frame structure that can make full use of space, improve storage capacity utilization, and expand storage capacity. Goods stored in the shelves do not squeeze each other, resulting in little material loss. The functions of the materials themselves can be fully guaranteed and the loss of goods can be reduced. The goods in the shelves are easy to access and count and measure to improve the quality of material storage.

[0003] Compared with the actual use process, the existing storage shelf columns currently use multiple bolts for fixing when splicing and docking. Due to the rich specifications of the goods placed on the shelves, the height of the goods storage mechanism of the shelves needs to be frequently changed, which requires the columns to be frequently disassembled and reassembled. The bolts will be stripped after long-term use. At the same time, multiple fixing bolts will slow down the assembly speed of the operator when fixing.

[0004] Therefore, in order to solve the above problems, the present application provides a stable docking device for storage shelf columns.

[0020] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 4A stable docking device for storage shelf columns includes a support frame 1, four support frames 1 are slidably embedded with three rail plates 2 between each other, and the inner end surfaces of the four support frames 1 are penetrated with a docking slide groove 3, the top and bottom ends of the docking slide groove 3 have a diameter larger than the middle, and the diameter of the connection between the limit rod 4 and the rail plate 2 is smaller than the diameter of the other end. In order to allow the limit rod 4 to enter the inside of the docking slide groove 3 and be limited by the docking slide groove 3 at the same time, the limit rod 4 is slidably embedded in the inner side of the docking slide groove 3, and docking fitting rods 5 are welded on both sides of the top of the rail plate 2. A limit frame 6 is arranged at one end of the inner side of the support frame 1, and buffer slide grooves 7 are penetrated at both ends of the limit frame 6. Slide rods 8 are slidably embedded in the two buffer slide grooves 7, and the two slide rods 8 are slidably embedded in the inner side of the two buffer slide grooves 7. A sleeve frame 9 is welded with the intermediate clamp in order to fix the docking interlocking rod 5, the sleeve frame 9 is sleeved on the outside of the docking interlocking rod 5, the outer diameter of the bottom end of the docking interlocking rod 5 is smaller than the outer diameter of the top end thereof, a flip seat 10 is welded on the outside of one end of the limiting frame 6, an extension rod 11 is rotatably connected to the inside of the flip seat 10, a rotating plate 12 is welded at one end of the extension rod 11, and a rotation limiter 13 is installed on the outside of one end of the flip seat 10. In order to limit the rotation of the fixing mechanism, a connecting rod 14 is rotatably connected to the outside of one end of the sleeve frame 9, and one end of the connecting rod 14 is rotatably connected to the middle of the top of the rotating plate 12. The rotation limiter 13 is a bolt limiter, one end of which is rotatably connected to the extension rod 11 and fits the rotating shaft inside the flip seat 10, and a placement plate 15 is embedded at the top of each two rail plates 2.

[0023] Working principle: First, the operator needs to adjust the vertical spacing of the rail plate 2 according to the height of the goods to be placed. First, the operator determines the position of the support placement mechanism at the bottom, and then inserts a limit rod 4 welded at one end of the rail plate 2 into the bottom end of the docking slot 3 that is opened through the inner end of the rail plate 2, and then slides upward. Since the opening width of the top and bottom ends of the docking slot 3 is greater than the middle part, and the diameter of the connection between the limit rod 4 and the rail plate 2 is smaller than the unconnected part, this can prevent the limit rod 4 from escaping from the restriction of the docking slot 3 when in the middle part of the docking slot 3. Then the operator places the limit frame 6 at the inner end of the support frame 1, passes the sleeve frame 9 through the docking slot 3, and sleeves it on the outside of a docking interlocking rod 5 welded at the top end of the rail plate 2;

[0024] Then the operator loosens the rotation limiter 13 installed at one end of the flip seat 10 welded on the outside of one end of the limit frame 6, and then presses the rotating plate 12. At that time, the rotating plate 12 will rotate on the inside of the flip seat 10 with the extension rod 11 welded at one end of it. At the same time, the other end of the rotating plate 12 will tilt in the opposite direction of the pressing, and at the same time drive the connecting rod 14 connected to it to move, and the connecting rod 14 will drive the sleeve frame 9 connected to it to move. As the movement progresses, one end of the inner side of the sleeve frame 9 will be sleeved on the outside of the docking interlocking rod 5, and during this period, both ends of the sleeve frame 9 will The two welded sliding rods 8 slide inside the buffer slide grooves 7 that penetrate through the two ends of the limit frame 6. After the sleeve frame 9 is completely sleeved on the outside of the docking and engaging rod 5, the rotating plate 12 can no longer be pressed. At that time, the operator will tighten the rotation limiter 13, and then fix the other end of the track plate 2 to another supporting frame 1, and then fix the remaining track plates 2 in turn, and then embed the placement plate 15 on the inner side of the track plate 2 to complete the assembly of the shelf. This design makes the assembly process of the entire shelf more convenient, and the disassembly speed is also faster, which can improve the assembly efficiency of the shelf.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
