[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] Reference Figure 1-7 As shown, a foldable beam includes a first beam 1 and a second beam 2. The first beam 1 and the second beam 2 are provided with a hinge structure 4 on their mating first edge 3, and the first beam 1 and the second beam 2 can rotate between each other with the hinge structure 4 as the fulcrum. A locking member 7 is provided on the second edge 5 on the opposite side of the first edge 3 to lock the overlapping state of the first beam 1 and the second beam 2.

[0023] The first beam 1 and the second beam 2 are rectangular tubes, and the first edge 3 and the second edge 5 are the shorter beam edges respectively. Specifically, the hinge structure 4 is located on the bottom beam edge, and the locking member 6 is located on the top beam edge.

[0024] Specifically, the hinge structure 4 includes at least one hinge groove 41 disposed at the first edge 3 of the first beam 1. Preferably, the number of hinge grooves 41 can be set to two. It also includes at least one hinge protrusion 42 disposed at the first edge 3 of the second beam 2 and cooperating with the hinge groove 41. Preferably, the hinge protrusion 42 is embedded in the hinge groove 41, and the number of the hinge protrusion 42 is set to two. At the same time, the hinge protrusion 42 can be formed in the middle part of the two hinge grooves 41. Similarly, the hinge groove 41 can be formed in the middle part of the two hinge protrusions 42. Meanwhile, in order to ensure that it can rotate, a rotating shaft 43 is provided to pass through both the hinge groove 41 and the hinge protrusion 42.

[0025] Furthermore, to avoid interference between the first beam 1 and the second beam 2 during rotation, a guide arc 31 is provided on the first edge 3 of the first beam 1. Similarly, the same guide arc 31 is provided on the first edge 3 of the second beam 2, and the radii of the two guide arcs 31 are the same.

[0026] The locking component 7 includes two sets of bases 71 disposed on the top surfaces of the first beam 1 and the second beam 2 and located on both sides of the mating end. Each base 71 has a locking hole 711 at its center. A locking screw 72 passes through the locking holes 711 on both bases 71. After the tail of the locking screw 72 passes through the base 71, a locking nut 73 is screwed into the locking screw 72 to provide a tightening function.

[0027] Meanwhile, it should be noted that, in order to further ensure the clamping strength between the first beam 1 and the second beam 2, fasteners 6 are provided on the sides of the first beam 1 and the second beam 2. Specifically, the fasteners 6 include fastening strips 61 and fastening screws 62. The fastening strips 61 are evenly divided along their length by the side splicing seam of the first beam 1 and the second beam 2. In addition, fastening holes are provided on both sides of the fastening strips 61 along their length. The fastening screws 62 pass through the sides of the first beam 1 and the second beam 2 from the sides and are screwed into the fastening holes at both ends of the fastening strips 61.

[0028] Meanwhile, it should be noted that in order to ensure that the second beam 2 can smoothly cooperate with the fastening strip 61 after rotation, a guide edge 611 is provided on the fastening strip 61 and on the side close to the second beam 2. Specifically, the guide edge 611 is located on the bottom edge and side edge (close to one end of the second beam) of the fastening strip 61.

[0029] It should be noted that the fastening strip 61 is installed on the inner wall side of the first beam 1 and the second beam 2. This arrangement can hide the fastening strip 61. Furthermore, the fastening screw 62 is a countersunk screw, which can further ensure the flatness of the outer surface of the first beam 1 and the second beam 2.

[0030] The working process of this utility model is as follows: In the initial state, the hinge protrusion 42 of the second beam 2 is inserted into the hinge groove 41 of the first beam 1. The second beam 2 is rotatably mounted on the first beam 1 through the rotating shaft 43, which ensures foldable packaging. During assembly, the fastening strip 61 is placed on the inner side wall of the first beam 1, and the fastening strip 61 is fixed to the first beam 1 by the fastening screw 62. By rotating the second beam 2, the second beam 2 moves closer to the fastening strip 61, and the side wall of the second beam 2 contacts the guide edge 611 on the fastening strip 61. The fastening strip 61 temporarily deforms and... To ensure that the end face of the second beam 2 is completely in contact with the end face of the first beam 1, the second beam 2 cannot easily detach from the first beam 1 due to the rebound of the fastening strip 61. Then, the fastening strip 61 is fixed to the second beam 2 by the fastening screw 62. The first beam 1 and the second beam 2 are spliced ​​in an extended shape. Finally, the tail of the locking screw 72 is inserted into the locking hole 711 of one of the bases 71 and the tail of the locking screw 72 is passed out into the locking hole 711 of the other base 71. The locking nut 73 is screwed into the tail of the locking screw 72 to lock and tighten the whole.
