[0047] Embodiment:

[0048] Referring to Figure 1 and Figure 2 The present embodiment provides a support panel which can be used in a storage rack, and the size specification of the support panel determines the size specification of the storage rack. The support panel comprises at least two support units, and the number of support units contained in the support panel is an important factor in determining the size specification of the support panel.

[0049] The support unit includes a connector 1 and a support rod 2. The connector 1 is mounted at the end of the support rod 2. Generally, each support unit includes two connectors 1, so that the connector 1 can be installed at both ends of the support rod 2. The support rods 2 are arranged side by side. The length of the support rods 2 determines the length of the support panel, and the number of support rods 2 determines the width of the support panel. For two adjacent support units, the connector 1 on one support rod 2 is connected to the connector 1 on the other support rod 2, so that the two adjacent support units are combined.

[0050] See also Figure 3 、 Figures 9-11 The connecting member 1 includes a main body 11, a first connecting portion 12, a first plug-in rod 13 and a second connecting portion 15.

[0051] A second insertion hole 111 is defined in the body 11 . The second insertion hole 111 extends along the axial direction (first direction) of the support rod 2 to allow the end of the support rod 2 to be inserted into the second insertion hole 111 .

[0052] The first connecting portion 12 is disposed on the outer wall of the body 11, and the first plugging rod 13 is fixed to the first connecting portion 12 and located on the side of the first connecting portion 12 facing away from the body 11. For example, in this embodiment, the first connecting portion 12 is generally elongated, with its ends respectively fixed to the outer wall of the body 11 and the first plugging rod 13. The first plugging rod 13 also extends in the first direction. Thus, the first plugging rod 13, the first connecting portion 12, and the body 11 form a clearance opening 14.

[0053] The second connecting portion 15 is also fixed on the outer wall of the body 11 and is located on the side of the body 11 away from the first connecting portion 12. A first plug hole 151 is defined on the second connecting portion 15. The extension direction of the first plug hole 151 is parallel to the extension direction of the first plug rod 13.

[0054] See Figure 3 For two adjacent connectors 1, the first plugging rod 13 of one connector 1 is plugged into the first plugging hole 151 of the other connector 1, and the second connecting portion 15 of one connector 1 can enter the avoidance opening 14 of the other connector 1. Through this matching relationship, at least two connectors 1 can be connected in sequence to achieve the assembly between at least two adjacent support units, thereby changing the number of support units included in the support panel, greatly expanding the size and specification options of the support panel, allowing the support panel to better adapt to the room size and user needs.

[0055] In order to prevent the first plug-in rod 13 from being separated from the first plug-in hole 151 and increase the assembly stability of the first plug-in rod 13 in the first plug-in hole 151, a first positioning rib 131 is arranged on the outer wall of the first plug-in rod 13, and a first limiting groove 152 is arranged on the side wall of the first plug-in hole 151. The first positioning rib 131 extends along the circumference of the first plug-in rod 13, the first limiting groove 152 extends along the circumference of the side wall of the first plug-in hole 151, and the first positioning rib 131 is located in the first limiting groove 152, so that the first plug-in rod 13 is axially positioned at the first plug-in hole 151.

[0056] The outer diameter of the first plug-in rod 13 is matched with the inner diameter of the side wall of the first plug-in hole 151, so that the first positioning rib 131 needs to be pressed against the side wall of the first plug-in hole 151 before entering the first limiting groove 152, so that the side wall of the first plug-in hole 151 avoids the movement of the first positioning rib 131 by deformation.

[0057] In order to increase the deformation ability of the side wall of the first plug-in hole 151, a deformation gap 153 is arranged on the side wall of the first plug-in hole 151, and the deformation gap 153 penetrates from the side wall of the first plug-in hole 151 to the outer wall of the second connecting part 15, and also extends to the opening of the first plug-in hole 151. Before the first positioning rib 131 enters the first limiting groove 152, the deformation gap 153 can allow the first plug-in hole 151 to be flared to better avoid the first positioning rib 131.

[0058] Referring to Figures 4-8 , and Figure 12 and Figure 13 , the support rod 2 comprises an inner tube 21, an outer tube 22 and a lock core 23. The inner tube 21 is slidingly arranged in the middle of the outer tube 22 to allow the length of the support rod 2 to be adjusted, and accordingly, the length of the support panel also has more choices.

[0059] Among them, at least two first locking holes 211 are arranged on the side wall of the inner tube 21, and the first locking holes 211 are arranged in sequence and spaced apart along the axis of the inner tube 21. A second locking hole 221 is arranged on the side wall of the outer tube 22, and the lock core 23 is located at the second locking hole 221 and can move radially in the outer tube 22.

[0060] Correspondingly, the support rod 2 has a locked state and an unlocked state.

[0061] When the support rod 2 is in the locked state, the second locking hole 221 is communicated to one of the first locking holes 211, the lock core 23 is arranged in the first locking hole 211 and the second locking hole 221, and the side wall of the first locking hole 211 abuts on the lock core 23 along the axis of the inner tube 21, so that the inner tube 21 is axially positioned on the outer tube 22, and the length of the support rod 2 is locked.

[0062] When the support rod 2 is in the unlocked state, the first locking hole 211 and the second locking hole 221 are staggered, the inner tube 21 outer wall blocks at the second locking hole 221, the lock core 23 is located on the inner side of the inner tube 21 and abuts on the inner wall of the inner tube 21. The friction between the lock core 23 and the inner wall of the inner tube 21 is small, which is not enough to play an axial positioning effect on the inner tube 21, so the inner tube 21 can slide in the outer tube 22 to allow the length of the support rod 2 to be adjusted.

[0063] As one of the assembly methods of the lock core 23, the support rod 2 further comprises a locking seat 24 and an elastic piece 25. The locking seat 24 is fixed on the outer tube 22, and the two ends of the elastic piece 25 are arranged on the locking seat 24 and the lock core 23 respectively. Among them, the locking seat 24 is provided with a guide groove 241, and the lock core 23 is slidingly arranged at the guide groove 241, so as to ensure that the moving direction of the lock core 23 is always along the radial direction of the outer tube 22.

[0064] Correspondingly, the inner tube 21 side wall is provided with an avoiding groove 212 extending along the axial direction of the inner tube 21, and the locking seat 24 is located at the avoiding groove 212. When the inner tube 21 slides in the outer tube 22, the inner tube 21 can avoid the locking seat 24 through the avoiding groove 212.

[0065] Preferably, the lock core 23 comprises a cylindrical portion 231 and a conical portion 232. The cylindrical portion 231 is generally cylindrical, and the conical portion 232 is generally conical. The end of the elastic piece 25 is located on one of the end faces of the cylindrical portion 231, and the bottom surface of the conical portion 232 is fixed on the other end face of the cylindrical portion 231.

[0066] When the support rod 2 is in the locked state, the cylindrical portion 231 is at least partially located in the first locking hole 211, and the side wall of the first locking hole 211 abuts on the side wall of the cylindrical portion 231 along the axial direction of the inner tube 21, and at least the tip portion of the conical portion 232 is located on the outside of the outer tube 22. To convert the support rod 2 from the locked state to the unlocked state, only the tip portion of the conical portion 232 needs to be pressed, so that the cylindrical portion 231 completely enters the inside of the inner tube 21, and then the inner tube 21 is moved. During the movement of the inner tube 21, the side wall of the first locking hole 211 will extrude the conical surface of the conical portion 232, thereby generating a component force of pressing the conical portion 232 into the inside of the inner tube 21, until the tip of the conical portion 232 also enters the inside of the inner tube 21 and abuts on the inner wall of the inner tube 21.

[0067] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0068] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the concept of the utility model, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
