[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. Thus, a feature pointed out in this specification will be used to illustrate one feature of one embodiment of the present utility model, rather than implying that each embodiment of the present utility model must have the feature described. In addition, it should be noted that this specification describes many features. Although certain features may be combined together to show a possible system design, these features may also be used in other combinations not specifically described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0038] The principle and structure of the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0039] In one embodiment, with reference to the attached Figure 1-3 , the present utility model provides a support frame, which includes at least two cross bars 10 and at least two longitudinal bars 20. The cross bars 10 and the longitudinal bars 20 can enclose a rectangular or square placement space 30 for installing a storage shelf board 70. At both ends of one side of each longitudinal bar 20 facing the cross bar 10, tenons 40 are extended outward. A triangular support plate 50 is provided near each tenon 40 on each longitudinal bar 20, and a clamping block 501 is provided on one side of each support plate 50 facing the corresponding tenon 40.

[0040] At both ends of the cross bar 10, matching bayonets 101 are provided corresponding to each clamping block 501.

[0041] When the cross bar 10 and the longitudinal bar 20 enclose, one end of the cross bar 10 can be inserted into the corresponding tenon 40, and the clamping block 501 can be clamped with the corresponding bayonet 101.

[0042] In this embodiment, preferably two cross bars 10 and two longitudinal bars 20 are provided, and the connection relationships between the tenons 40, the support plates 50 and the longitudinal bars 20 are preferably welded.

[0043] Among them, when two cross bars 10 and two longitudinal bars 20 are to enclose a rectangular support frame, first insert one end of the cross bar 10 into the tenon 40 of the longitudinal bar 20 correspondingly, and at the same time insert the clamping block 501 into the bayonet 101 and clamp it. Then install the two cross bars 10 on the corresponding two longitudinal bars 20 in turn, so that the cross bar 10 can be firmly fixed on the corresponding longitudinal bar 20 to improve the load-bearing performance of the support frame.

[0044] Among them, the specific structure between the clamping block 501 and the bayonet 101 can be referred to the attached Figure 2 , a "C"-shaped slot 504 is formed between the clamping block 501 and the adjacent support plate 50.

[0045] When the clamping block 501 extends into the bayonet 101, the "C"-shaped slot 504 can be clamped with the side wall of the corresponding bayonet 101 away from the longitudinal bar 20.

[0046] In this way, the cross bar 10 can be stably clamped on the corresponding longitudinal bar 20 to improve the load-bearing performance of the support frame.

[0047] Among them, with reference to the attached Figure 2 , at one side of each support plate 50 facing the corresponding tenon 40 and at one end connecting the longitudinal bar 20, a first notch 502 is formed by inward depression.

[0048] Since welding the tenon 40 and the supporting plate 50 on the longitudinal rod 20 is performed in steps, when the tenon 40 or the supporting plate 50 is welded first, the first notch 502 provided on the supporting plate 50 will not affect the supporting plate 50 or the tenon 40 welded later.

[0049] Wherein, in order to more conveniently install the cross bar 10, refer to the attached Figure 2 and 5 Both ends of the tenon 40 away from the correspondingly connected longitudinal rod 20 are recessed inward to form a second notch portion 401.

[0050] Because a block 501 is provided on the side of the support plate 50 facing the tenon 40, in order to prevent the block 501 from affecting the installation of the cross bar 10, second notches 401 are provided at both ends of the side of the tenon 40 away from the longitudinal bar 20, so that the cross bar 10 can be smoothly installed on the corresponding longitudinal bar 20.

[0051] Among them, refer to the attached Figure 2 and 4 Each of the tenons 40 is provided with a circular first through hole 402 , and each of the cross bars 10 is provided with a circular guide hole 102 corresponding to the first through hole 402 .

[0052] When the cross bar 10 is connected to the mortise and tenon 40, the centers of the first through hole 402 and the guide hole 102 are located on the same vertical line, so that a screw can be passed through the spring washer, and then passed through the guide hole 102 and the corresponding first through hole 402 from the side of the cross bar 10 toward the ground to form a threaded connection, so as to further improve the load-bearing performance of the support frame. Of course, after the screw passes through the guide hole 102 and the corresponding first through hole 402, glue can be injected into the connection or the connection can be welded. The screw will not pass through the side of the cross bar 10 away from the ground, so that the screw can be hidden to improve the aesthetics of the support frame or the shelf.

[0053] Among them, refer to the attached Figure 2 A second through hole 503 is provided in the middle of each supporting plate 50 .

[0054] In this way, when the storage layers 70 are placed on the support plates 50 at the four corners of the placement space 30, bolts are passed through the second through holes 503 from the bottom of the support plates 50 and then connected to the support plates 50 accordingly, so as to more stably fix the storage layers 70 on the support plates 50. The bolts will not penetrate the storage layers 70, so that the bolts can be hidden, thereby improving the aesthetics of the support frame or the storage rack.

[0055] In order to reduce the weight of the support frame, reduce the material usage of the support frame, and reduce the cost of the support frame, the cross bar 10 and the longitudinal bar 20 are both hollow structures.

[0056] The crossbar 10, the longitudinal bar 20, the tenon 40 and the supporting plate 50 are made of any one of carbon steel, stainless steel and aluminum alloy. In this embodiment, the crossbar 10, the longitudinal bar 20, the tenon 40 and the supporting plate 50 are preferably made of carbon steel, so that the supporting frame made in this way has good load-bearing performance and high cost performance.

[0057] The cross bar 10 and the longitudinal bar 20 are in the shape of a round tube or a square tube.

[0058] The structure of the tenon 40 is an L-shaped plate structure, which can be more conveniently inserted into the cross bar 10 to further improve the load-bearing performance of the support frame. Of course, the structure of the tenon 40 can also be a rectangular plate structure or other structure that is convenient for installing the cross bar 10, which is not limited here.

[0059] In one embodiment, the utility model further provides a storage rack, comprising the above-mentioned supporting frame.

[0060] Among them, refer to the attached Figure 6 A support rod 60 is welded to each end of the longitudinal rod 20, and then the cross bar 10 is clamped with the corresponding longitudinal rod 20 to form a support frame, and a storage layer plate 70 is installed on the support frame to form a storage rack. At this time, the support rod 60 is a square tube or a round tube made of carbon steel. Of course, at least one layer of support frame is provided on the storage rack.

[0061] In other embodiments (not shown in the figures), a cone sleeve is welded to each end of the longitudinal rod 20, and the support rod 60 passes through and is sleeved on the corresponding cone sleeve. The cross bar 10 is then clamped with the corresponding longitudinal rod 20 to form a support frame, and a storage layer plate 70 is installed on the support frame to form a storage rack. Of course, at least one layer of support frame is provided on the storage rack.

[0062] Among them, the support rod 60 is preferably a bamboo tube, so that when the support frame is detachably sleeved on the corresponding support rod 60, the height between the upper and lower adjacent support frames can be adjusted at will to adapt to the storage of items of different sizes. This flexibility ensures that the shelf can adapt to various storage needs and improves practicality; and the design of the bamboo tube makes the assembly and disassembly of the shelf very simple, and the user can easily complete the assembly process without using any tools, which not only improves the installation efficiency but also reduces the installation cost; and the structure of the bamboo tube is sturdy and durable, and can effectively support the support frame, thereby enhancing the stability of the entire shelf, which enables the shelf to withstand more weight and is not easily deformed or damaged during use.

[0063] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive. Although the utility model is described in detail with reference to the aforementioned embodiments, for those skilled in the art, it is still possible to modify the technical solutions recorded in the aforementioned specific implementation methods, or to replace some of the technical features therein with equivalents. Any equivalent structure made using the contents of the utility model specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of patent protection of the utility model.
