[0034] The present application provides a storage rack, which comprises a vertical rod assembly 1 and a storage member, the number of vertical rod assemblies 1 is at least two, the at least two vertical rod assemblies 1 are arranged at intervals, the vertical rod assembly 1 comprises a support rod 11, a cap 12 and a first fixing piece 13, the cap 12 is arranged at the top end of the support rod 11, the cap 12 is provided with a fixing hole 14, the first fixing piece 13 is arranged in the fixing hole 14, the bottom end of the support rod 11 is configured to abut against the ground, and the cap 12 is configured to be fixedly connected with the ceiling through the first fixing piece 13; the storage member is arranged between the adjacent two vertical rod assemblies 1.

[0035] Specifically, the cross section of the cap 12 is circular, the cap 12 is in the shape of a circular disc as a whole, the cross section size of the cap 12 is larger than the cross section size of the support rod 11, the support rod 11 is located at the middle of the cap 12, and the fixing holes 14 are located on both sides of the support rod 11, so as to avoid the support rod 11 from affecting the insertion of the first fixing member 13.

[0036] Specifically, the stand pole assembly 1 further comprises a support leg 15, which is arranged at the bottom end of the support rod 11, and the support rod 11 is arranged on the ground through the support leg 15, so as to reduce the abrasion of the ground caused by the direct contact of the support rod 11 with the ground.

[0037] Specifically, the first fixing member 13 is an expansion screw. In this embodiment, a bolt with a specification of M5x45 is used, and an expansion pipe with a specification of M5x45 is used.

[0038] Specifically, this embodiment is suitable for the case that the back wall is not suitable for expansion screws, the top wall is suitable for expansion screws, and the case that there is no back wall. When the ceiling wall is not suitable for expansion screws and the back wall is suitable for expansion screws, the material of the back wall is red brick, light brick, ceramic tile, formwork, light steel gypsum board (inner wooden board), and another embodiment is provided, which is described with reference to Figure 4 The difference between this embodiment and the other embodiment is that the support rod 11 in the other embodiment is in the shape of “L” to fix the shelf on the back wall.

[0039] With reference to Figure 2 and Figure 3 , the support rod 11 comprises a first support rod 111 and a second support rod 112, the first support rod 111 is sleeved outside the second support rod 112, the first support rod 111 can move along the axial direction of the second support rod 112 to realize the extension and contraction of the support rod 11, the bottom end of the first support rod 111 is configured to abut against the ground, the cap 12 is arranged at the top end of the second support rod 112, and the support leg 15 is arranged at the bottom end of the first support rod 111.

[0040] Specifically, the first support rod 111 is in the shape of a cuboid, and the second support rod 112 is in the shape of an I-beam as a whole.

[0041] Specifically, the top surface of the cap 12 is a plane, and the area of the top surface of the cap 12 is greater than the cross-sectional area of the second support rod 112, which can increase the contact area of the cap 12 and the ceiling.

[0042] Specifically, the bottom surface of the support foot 15 is a plane, and the area of the bottom surface of the support foot 15 is greater than the cross-sectional area of the first support rod 111, which can prevent the support rod 11 from tilting.

[0043] The material of the vertical rod assembly 1 can be plastic or metal. When the material is plastic, the cap 12 and the second support rod 112 are integrally formed. When the material is metal, the cap 12 is welded to the top end of the second support rod 112.

[0044] Specifically, the height of the shelf in the prior art is mostly fixed, which cannot meet the requirements of different house heights and needs to be customized in size. The shelf of the present application is telescopic, suitable for a floor height of 2.1-3 meters, covering all conventional floor heights, and has wide adaptability, does not need to be stocked in multiple specifications, can be mass-produced, and saves costs. In addition, the shelf of the present application is fixed to the wall by the vertical rod assembly 1, compared with the prior art in which the horizontal rail is fixed to the wall and the vertical rod assembly is connected with the horizontal rail, the present application omits the horizontal rail and saves costs.

[0045] Reference Figure 2 and Figure 3 The side wall of the first support rod 111 is provided with a first through hole 113, and the support rod 11 further comprises a second fixing member 16, which is sequentially arranged in the first through hole 113 and abuts against the second support rod 112, so as to fix the first support rod 111 relative to the second support rod 112.

[0047] Specifically, the number of first through holes 113 is at least one, and in this embodiment, the number of first through holes 113 is two and arranged in an up-down manner, which increases the stability of the second support rod 112 relative to the first support rod 111 and prevents relative sliding.

[0048] Specifically, the second fixing member 16 is a bolt. In this embodiment, a bolt with specifications M5x8 is used.

[0049] In other embodiments, the side wall of the second support rod 112 is provided with a plurality of grooves, the grooves are arranged along the axial direction of the second support rod 112, and the second fixing member 16 is sequentially arranged in the first through hole 113 and the grooves to fix the first support rod 111 relative to the second support rod 112.

[0050] During installation, the cap 12 abuts against the ceiling, the cap 12 is fixedly connected with the ceiling through the first fixing member 13, then the second fixing member 16 is loosened, the first support rod 111 is slowly free-falling along the axial direction of the second support rod 112 until the supporting leg 15 contacts the ground, then the second fixing member 16 is tightened, and the installation of the vertical rod assembly 1 is completed.

[0051] Referring to Figure 5 and Figure 6 , the shelf further comprises a support arm assembly, the support arm assembly comprises two support arms 3, the two support arms 3 are oppositely arranged, and in the two adjacent vertical rod assemblies 1, one of the two support arms 3 is arranged on the side wall of one of the vertical rod assemblies 1, and the other of the two support arms 3 is arranged on the side wall of the other of the vertical rod assemblies 1, and the two support arms 3 are used for supporting the storage member.

[0052] Referring to Figure 5 and Figure 6 , the side wall of the first support rod 111 is provided with a mounting hole 114, the support arm 3 comprises a support arm body 31 and a clamping jaw 32, the support arm body 31 comprises a middle section 311 and two connecting sections 312, the two connecting sections 312 are arranged at two ends of the middle section 311 respectively, and the width of the connecting section 312 gradually decreases from one end connected to the middle section 311 to the other end away from the middle section 311; in this embodiment, the support arm body 31 is in a plate shape. The clamping jaw 32 is arranged on the side surface of the support arm body 31, and the clamping jaw 32 is arranged on the middle section 311, the support arm 3 is fixedly connected with the vertical rod assembly 1 by being clamped into the mounting hole 114 of the first support rod 111 through the clamping jaw 32.

[0053] Specifically, the middle section 311 and the two connecting sections 312 are integrally arranged, the vertical cross section of the middle section 311 is in a rectangular shape, and the vertical cross section of the connecting section 312 is substantially in a triangular shape.

[0054] The support arm 3 of the present application can ensure that the support arm 3 has balanced stress points when being connected with the first support rod 111 by arranging the two connecting sections 312 with the same structure at two ends of the middle section 311, and the clamping jaw 32 is arranged on the middle section 311, so that the support arm 3 can effectively disperse the load when being stressed, the distribution of the clamping jaw 32 and the arrangement of the connecting section 312 help to uniformly transmit the force to both ends of the support arm 3, avoiding that the support arm 3 is stressed at only one end, reducing the damage or deformation of the component caused by uneven stress, and improving the durability of the support arm 3.

[0055] Since the force point is in the middle, by setting the width of the connecting section 312 to gradually decrease from one end of the connecting middle section 311 to the other end away from the middle section 311, it can help the support arm 3 distribute the force, so that each part of the support arm 3 can bear the external load more evenly when the support arm 3 is under stress, which helps to achieve optimal force transmission and structural stability. This is because the part close to the middle section 311 bears a larger pressure, so the width is larger, while the part away from the middle section 311 bears a smaller pressure, so the width gradually decreases, which helps to achieve optimal force transmission and structural stability, and also avoids overuse of materials.

[0056] Specifically, the middle section 311 has a first straight section 313, the connecting section 312 has a second straight section 314, the first straight section 313 and the second straight section 314 are arranged at an angle, and the first straight section 313 and the second straight section 314 are arc transitioned at the connecting corner to form an arc section 315. The support arm 3 further comprises a flange portion 33, the flange portion 33 is located on the same side of the support arm body 31 as the clamping jaw 32, and protrudes from the side surface of the support arm body 31.

[0059] A clamping space is formed between the two first flanges 331, which matches the first support rod 111. When the support arm 3 is installed in the mounting hole 114 of the first support rod 111, the two first flanges 331 cooperate to clamp the first support rod 111, so that the support arm 3 can firmly clamp the first support rod 111, and the support arm 3 can avoid shaking on the first support rod 111, further improving the connection stability. In addition, when the support arm 3 and the first support rod 111 are tightly matched by the two first flanges 331, the force point is increased, so that the force can be more evenly distributed between the support arm 3 and the first support rod 111, further avoiding the occurrence of local excessive force, and improving the durability and reliability of the support arm 3.

[0060] Specifically, the number of clamping jaws 32 is multiple, and the multiple clamping jaws 32 are arranged in a rectangular array.
