Abstract

According to the rivet hanging claw, an eccentric rivet is arranged on a cross beam column clamp, and the eccentric rivet comprises a fixing part fixed to the cross beam column clamp, a buckle part located on the side face of the fixing part and a hook part located on the outer side of the buckle part. The distance from the bottom of the hook part to the bottom of the buckling part is larger than the distance from the top of the hook part to the top of the buckling part, that is, under the condition that the rivet is as high as a rivet in the prior art, the length of the portion, achieving the actual limiting function, of the hook part at the lower end of the rivet is longer, and the risk that the beam column clamp falls off a stand column hole can be reduced; and the torque borne by the eccentric rivet is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of warehousing equipment, especially the shelf structure. Background Art

[0002] In the connection between the shelf upright column and the cross beam, generally, the cross beam column clamp is hung on the upright column by rivets. The goods position loads the load on the cross beam, and the cross beam conducts it to the upright column through the rivets of the column clamp. The rivets of the cross beam column clamp are the key load-bearing units.

[0003] Most of the existing rivets of the cross beam column clamp have a vertically symmetric structure. Only the lower part of the rivet actually plays a limiting role, and it is relatively small, resulting in a relatively high probability that the rivets of the cross beam column clamp fall out of the front hole of the upright column. Moreover, the upper part of the rivet is useless, occupying space and wasting resources. The upper part of the rivet also causes a relatively large distance between the safety pin on the cross beam column clamp and the rivet, and then leads to a relatively long front hole of the upright column in the vertical direction, affecting the safety of the cross beam column clamp and the effect of the hanging claw, and indirectly affecting the load-bearing effect of the upright column.

[0004] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the Invention

[0005] The present invention provides a rivet hanging claw for preventing the cross beam from falling off, aiming to reduce the risk of the rivets of the cross beam column clamp falling out of the holes of the upright column and improve the torque that the rivets can withstand when fixed to the upright column.

[0006] The present invention also provides a shelf with the rivet hanging claw for preventing the cross beam from falling off.

[0007] To achieve the above purpose, the rivet hanging claw for preventing the cross beam from falling off of the present invention can adopt the following technical solutions:

[0008] A rivet hanging claw for preventing the cross beam from falling off, including a cross beam column clamp, and an eccentric rivet is provided on the cross beam column clamp. The eccentric rivet includes a fixing part fixed on the cross beam column clamp, a buckling part located on the side of the fixing part, and a hanging hook part located outside the buckling part. The buckling part is located between the fixing part and the hanging hook part; the bottom of the buckling part is arc-shaped, and the distance from the bottom of the hanging hook part to the bottom of the buckling part is greater than the distance from the top of the hanging hook part to the top of the buckling part.

[0009] Further, the top of the hanging hook part is at the same height as the top of the buckling part, and the bottom of the hanging hook part is lower than the bottom of the buckling part, jointly forming a hanging hook shape with the buckling part.

[0010] Further, the buckling part is a cylinder, and the hanging hook part is an elliptical cylinder; the central axis of the hanging hook part is eccentrically arranged with the central axis of the buckling part, and the width of the hanging hook part is the same as the diameter of the buckling part.

[0011] Further, the radian of the top of the hook part is the same as that of the top of the buckle part, so that the tops of the hook part and the buckle part together form a continuous and flat arc surface.

[0012] Further, the crossbeam column clip includes a first plate member and a second plate member arranged perpendicular to each other. The first plate member is used to connect the crossbeam, and the eccentric rivet is installed on the second plate member; the fixing part penetrates through the second plate member for fixation, and one side surface of the buckle part connected to the fixing part abuts against the surface of the second plate member.

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

[0014] Beneficial effects: Compared with the prior art, the eccentric rivet adopted in the present technical solution removes the upper part of the hook part compared with the prior art, so that the distance from the bottom of the hook part to the bottom of the buckle part is greater than the distance from the top of the hook part to the top of the buckle part. That is, at the same height as the rivet in the prior art, the length of the part of the lower hook part of the rivet in this solution that plays the actual limiting function is longer, which can be used to reduce the risk of the crossbeam column clip falling off the column hole. At the same time, also because at the same height as the rivet in the prior art, the length of the part of the lower hook part that plays the actual limiting function is longer, the lever of the contact part between the hook part and the column is longer, and the torque that the eccentric rivet can withstand is increased.

[0015] The shelf with the rivet claw for preventing the crossbeam from falling off provided by the present invention can adopt the following technical solutions:

[0016] A shelf with the rivet claw for preventing the crossbeam from falling off, including a crossbeam and a column. The crossbeam is fixedly connected to the crossbeam column clip, and the column and the crossbeam column clip are detachably connected by an eccentric rivet.

[0017] Further, a hole matching with the eccentric rivet is provided on the column. The hole includes an upper arc part and a lower arc part, and the height of the hole is greater than the height of the eccentric rivet. The diameter of the upper arc part is greater than the width of the eccentric rivet. The radian of the lower arc part is the same as the bottom radian of the buckle part, and the width of the lower arc part is the same as the width of the buckle part.

[0018] Further, the inner side of the hook part is closely attached to the surface of the column.

[0019] Beneficial effects: Compared with the prior art, on the basis of the above-mentioned rivet claw for preventing the crossbeam from falling off, the column and the crossbeam column clip are detachably connected by an eccentric rivet in this technical solution. Further, by providing a hole including an upper arc part and a lower arc part on the column and tightly matching it with the eccentric rivet, the crossbeam column clip can be tightly matched with the column.

[0028] Embodiment 1

[0029] Please refer to Figures 1 to 5 shown, the present invention discloses a rivet hanging claw for preventing the cross beam from falling off, including a cross beam column clamp 1 and an eccentric rivet 2 arranged on the cross beam column clamp. The cross beam column clamp 1 includes a first plate member 11 and a second plate member 12 which are arranged perpendicular to each other. The first plate member 11 is used to connect the cross beam 3, and the eccentric rivet 2 is installed on the second plate member 12. The eccentric rivet 2 includes a fixing portion 21 fixed on the cross beam column clamp 1, a buckling portion 22 located on the side of the fixing portion 21, and a hook portion 23 located outside the buckling portion 22. The fixing portion 21 penetrates and is fixed to the second plate member 12, and one side surface of the buckling portion 22 connected to the fixing portion 21 abuts against the surface of the second plate member 12. The number of the eccentric rivets 2 arranged on the cross beam column clamp 1 can be selected according to actual needs. For example, three to five eccentric rivets 2. In this embodiment, as Figure 1 shown, three eccentric rivets 2 are arranged on the cross beam column clamp 1, and all the eccentric rivets 2 are arranged in a column from top to bottom. The cross beam column clamp 1 is also provided with a safety pin 13. The safety pin 13 is used to assist the installation operation between the cross beam column clamp 1 and the column, which belongs to the prior art and will not be elaborated here.

[0030] Combined with Figure 4 and Figure 5As shown, the eccentric structure of the eccentric rivet 2 means that the central axis of the buckle part 22 is eccentrically arranged with the central axis of the hook part 23. Specifically: the buckle 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 arranged with the central axis of the elliptical cylinder of the buckle part 22; the width of the hook part 23 is the same as the diameter of the buckle part 22; that is, the bottom of the buckle part 22 is arc-shaped, and the distance from the bottom of the hook part 23 to the bottom of the buckle part 22 is greater than the distance from the top of the hook part 23 to the top of the buckle part 22. That is, at the same height as the existing technology rivet, the length of the part of the lower end hook part 23 of the rivet in this embodiment that plays the actual limiting function is longer.

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

[0032] Embodiment 2

[0033] Please combine Figure 6 As shown, this embodiment provides a shelf with a rivet claw for preventing the cross beam from falling off as described in Embodiment 1. The shelf includes a cross beam 3 and a column 4. The cross beam 3 is fixedly connected to the cross beam column clamp 1, and the column 4 and the cross beam column clamp 1 are detachably connected by an eccentric rivet 2.

[0034] Please combine Figure 7 and Figure 8 As shown, for the detachable connection, a hole 41 matching the eccentric rivet 2 is provided on the column 4. The hole 41 includes an upper arc part 42 and a lower arc part 43, and the height of the hole 41 is greater than the height of the eccentric rivet 2. The diameter of the upper arc part 42 is greater than the width of the eccentric rivet 2. The radian of the lower arc part 43 is the same as the bottom radian of the buckle part 22, and the width of the lower arc part 43 is the same as the width of the buckle part 22. When installing, as Figure 8 shown, first pass the whole eccentric rivet 2 through the hole 41 through the larger upper arc part 42, and then drop the eccentric rivet 2 downward into the hole 41 so that the bottom of the buckle part 22 falls into the lower arc part 43 to form close contact and lateral positioning (that is, Figure 7 the state shown in), and the inner side of the hook part 23 is in close contact with the surface of the column 4 to bear the torque. As described above, the length of the part of the hook part 23 in this invention that plays the actual limiting function is longer, that is, the lever of the part where the hook part 23 contacts the column 4 is longer, which can improve the torque that the whole eccentric rivet 2 can bear.

[0035] There are many methods and ways to specifically implement this technical solution in the present invention. The above description is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by existing technologies.
