Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment technology, and in particular to shelving structures. Background Technology

[0002] In the connection between the uprights and beams of the rack, the beams are usually attached to the uprights by rivets. The load is applied to the beams by the storage location, and the beams transmit the load to the uprights through the rivets. The beams and rivets are the key load-bearing units.

[0003] Existing beam-column clips are mostly symmetrical structures, with only the lower part of the rivet actually serving a limiting function, and this part is relatively small. This makes it relatively easy for the beam-column clip rivets to fall out of the front hole of the column. Meanwhile, the upper part of the rivet is useless, occupying space and wasting resources. The upper part of the rivet also results in a relatively large distance between the safety pin on the beam-column clip and the rivet, which in turn makes the front hole of the column relatively long in the vertical direction, affecting the safety of the beam-column clip and the effect of the claw, and indirectly affecting the load-bearing capacity of the column.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a rivet claw to prevent crossbeams from falling off, with the aim of reducing the risk of crossbeam column rivets falling out of column holes and increasing the torque that rivets can withstand when fixed to columns.

[0006] This utility model also provides a shelf with rivet claws that prevent the crossbeam from falling off.

[0007] To achieve the above objectives, the rivet hooks for preventing crossbeams from falling off in this utility model can adopt the following technical solution:

[0008] A rivet hook for preventing crossbeams from falling off includes a crossbeam post clip. The crossbeam post clip is provided with an eccentric rivet. The eccentric rivet includes a fixing part fixed to the crossbeam post clip, a snap-fit ​​part located on the side of the fixing part, and a hook part located outside the snap-fit ​​part. The snap-fit ​​part is located between the fixing part and the hook part. The bottom of the snap-fit ​​part is arc-shaped, and the distance from the bottom of the hook part to the bottom of the snap-fit ​​part is greater than the distance from the top of the hook part to the top of the snap-fit ​​part.

[0009] Furthermore, the top of the hook portion is at the same height as the top of the buckle portion, and the bottom of the hook portion is lower than the bottom of the buckle portion, thus forming a hook shape together with the buckle portion.

[0010] Furthermore, the buckle part is a cylinder, and the hook part is an elliptical cylinder; the central axis of the hook part is eccentrically set with respect to the central axis of the buckle part, and the width of the hook part is the same as the diameter of the buckle part.

[0011] Furthermore, the curvature of the top of the hook portion is the same as the curvature of the top of the buckle portion, so that the top of the hook portion and the top of the buckle portion together form a continuous and flat arc surface.

[0012] Furthermore, the crossbeam column clip includes a first plate and a second plate arranged perpendicularly to each other. The first plate is used to connect the crossbeam, and an eccentric rivet is installed on the second plate. The fixing part passes through the second plate for fixing, and the side of the buckle part connected to the fixing part abuts against the surface of the second plate.

[0013] Furthermore, at least three eccentric rivets are provided on the crossbeam column clamp, and all eccentric rivets are arranged in a row from top to bottom.

[0014] Beneficial effects: Compared to existing technologies, the eccentric rivet used in this solution eliminates the upper part of the hook portion, making the distance from the bottom of the hook portion to the bottom of the latching portion greater than the distance from the top of the hook portion to the top of the latching portion. In other words, at the same height as existing rivets, the lower hook portion of this solution provides a longer actual limiting function, reducing the risk of the beam column falling out of the column hole. Simultaneously, because the lower hook portion provides a longer actual limiting function at the same height as existing rivets, the leverage between the hook portion and the column is longer, increasing the torque that the eccentric rivet can withstand.

[0015] The shelving unit with the rivet claws that prevent the crossbeams from falling off, as provided by this utility model, can adopt the following technical solution:

[0016] A shelf with rivet claws for preventing beams from falling off includes beams and uprights, the beams being fixedly connected to beam uprights, and the uprights being detachably connected to the beam uprights via eccentric rivets.

[0017] Furthermore, the column is provided with a hole that mates with the eccentric rivet. The hole includes an upper arc portion and a lower arc portion. The height of the hole is greater than the height of the eccentric rivet, the diameter of the upper arc portion is greater than the width of the eccentric rivet, the curvature of the lower arc portion is the same as the bottom curvature of the buckle portion, and the width of the lower arc portion is the same as the width of the buckle portion.

[0018] Furthermore, the inner side of the hook portion is in close contact with the surface of the column.

[0019] Beneficial effects: Compared with the prior art, this technical solution, based on the aforementioned rivet claws that prevent the crossbeam from falling off, enables a detachable connection between the column and the crossbeam post clip via eccentric rivets. Furthermore, by providing holes including upper and lower arc portions on the column for fastening with the eccentric rivets, the crossbeam post clip can be securely fitted to the column.

[0028] Example 1

[0029] Please combine Figures 1 to 5 As shown, this utility model discloses a rivet hook to prevent a crossbeam from falling off, including a crossbeam post clip 1 and eccentric rivets 2 disposed on the crossbeam post clip. The crossbeam post clip 1 includes a first plate 11 and a second plate 12 disposed perpendicularly to each other. The first plate 11 is used to connect the crossbeam 3, and the eccentric rivets 2 are installed on the second plate 12. The eccentric rivet 2 includes a fixing part 21 fixed to the crossbeam post clip 1, a snap-fit ​​part 22 located on the side of the fixing part 21, and a hook part 23 located outside the snap-fit ​​part 22. The fixing part 21 passes through the second plate 12 for fixing, and the side of the snap-fit ​​part 22 connected to the fixing part 21 abuts against the surface of the second plate 12. The number of eccentric rivets 2 disposed on the crossbeam post clip 1 can be selected according to actual needs, for example, three to five eccentric rivets 2. In this embodiment, for example... Figure 1 As shown, the beam-column clip 1 is equipped with three eccentric rivets 2, and all the eccentric rivets 2 are arranged in a row from top to bottom. The beam-column clip 1 is also equipped with a safety pin 13. The safety pin 13 is used to assist in the installation work between the beam-column clip 1 and the column, which is existing technology and will not be described in detail here.

[0030] Combination Figure 4 and Figure 5 As shown, the eccentric structure of the eccentric rivet 2 refers to the fact that the central axis of the snap-fit ​​part 22 is eccentrically set with respect to the central axis of the hook part 23. Specifically, the snap-fit ​​part 22 is a cylinder, and the hook part 23 is an elliptical cylinder; the central axis of the cylinder of the hook part 23 is eccentrically set with respect to the central axis of the elliptical cylinder of the snap-fit ​​part 22; the width of the hook part 23 is the same as the diameter of the snap-fit ​​part 22; that is, the bottom of the snap-fit ​​part 22 is arc-shaped, and the distance from the bottom of the hook part 23 to the bottom of the snap-fit ​​part 22 is greater than the distance from the top of the hook part 23 to the top of the snap-fit ​​part 22. In other words, with the same height as existing rivets, the length of the hook part 23 at the lower end of the rivet in this embodiment, which performs the actual limiting function, is longer.

[0031] Combination Figure 4 and Figure 5 As shown, the top of the hook portion 23 is at the same height as the top of the buckle portion 22, and the curvature of the top of the hook portion 23 is the same as the curvature of the top of the buckle portion 22, so that the top of the hook portion 23 and the top of the buckle portion 22 together form a continuous and flat arc surface. The bottom of the hook portion 23 is lower than the bottom of the buckle portion 22, and together they form a hook shape.

[0032] Example 2

[0033] Please combine Figure 6 As shown, this embodiment provides a shelf with rivet claws to prevent the beam from falling off, as described in Embodiment 1. The shelf includes a beam 3 and an upright 4. The beam 3 is fixedly connected to the beam post clip 1, and the upright 4 is detachably connected to the beam post clip 1 by an eccentric rivet 2.

[0034] Please combine Figure 7 and Figure 8 As shown, for the detachable connection, the column 4 is provided with a hole 41 that mates with the eccentric rivet 2. This hole 41 includes an upper arc portion 42 and a lower arc portion 43. The height of the hole 41 is greater than the height of the eccentric rivet 2, the diameter of the upper arc portion 42 is greater than the width of the eccentric rivet 2, the curvature of the lower arc portion 43 is the same as the bottom curvature of the latching part 22, and the width of the lower arc portion 43 is the same as the width of the latching part 22. During installation, as... Figure 8 As shown, the eccentric rivet 2 is first passed through the hole 41 via the larger upper arc portion 42. Then, the eccentric rivet 2 is lowered into the hole 41 so that the bottom of the snap-fit ​​portion 22 falls into the lower arc portion 43 to form a tight contact and lateral positioning (i.e., Figure 7 As shown in the diagram, the hook portion 23 is in close contact with the surface of the column 4 to bear the torque. As mentioned above, the hook portion 23 in this utility model has a longer actual limiting function, that is, the lever of the part in contact between the hook portion 23 and the column 4 is longer, which can increase the torque that the eccentric rivet 2 can withstand as a whole.

[0035] There are many methods and approaches to implement this technical solution, and the above description is only a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
