[0002] There are a large number of bookshelves and compact shelving in the library, and the shelves are particularly important in the bookshelves and compact shelving. In actual use, it is found that in the existing technology, when the load is too large, the shelves are prone to deformation; when the compact shelving and bookshelf specifications are large, the shelves are inconvenient to carry; in the production process of large compact shelving and bookshelf, the shelf specifications are too large, which is inconvenient to produce and transport.

[0003] For example, the authorized patent document with application number 202022836007.0 discloses a foldable refrigerator shelf assembly, including a main shelf, and the four corners of the bottom of the main shelf are rotatably connected to a first connecting member, and the other end of the first connecting member is rotatably connected to an auxiliary shelf; by providing an auxiliary shelf at the bottom of the main shelf, the auxiliary shelf is connected to the main shelf through the first connecting member, so that the auxiliary shelf can be folded and stored at the bottom of the main shelf, and when the auxiliary shelf is not needed, the auxiliary shelf can be stored at the bottom of the main shelf to reduce the space occupied by the auxiliary shelf, and the main shelf and the auxiliary shelf are integrated, so that the auxiliary shelf is not easy to lose, and the auxiliary shelf is composed of two low shelves and a high shelf. When the height of the items to be placed at the bottom of the auxiliary shelf exceeds the low shelf, the high shelf can be stretched upward for placement, so that the heights of the two low shelves and the high shelf are different, thereby facilitating the utilization of the internal space of the refrigerator space.

[0004] The above patent exists. When the load-bearing capacity is too large, the shelf is prone to deformation. When the compact shelving and bookshelf are large in size, the shelf is inconvenient to carry. In the production process of large compact shelving and bookshelf, the shelf size is too large and inconvenient to produce and transport. Therefore, we need to provide a foldable shelf.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 The utility model provides a technical solution: a foldable shelf, comprising:

[0027] Two partition bodies 1, and a hinge assembly 2 arranged between the two partition bodies 1;

[0028] A slot 3 is provided inside the partition body 1;

[0029] A support mechanism 4 disposed inside the partition body 1 for enhancing the supporting force of the two partition bodies 1;

[0030] The supporting mechanism 4 includes a guide rail 41, a card slot 42, an insertion rod 43 and a card connection assembly 40. The guide rail 41 is fixedly installed inside the partition body 1, and the insertion rod 43 is slidably installed inside the guide rail 41. One end of the insertion rod 43 is slidably connected to the slot 3 inside the partition body 1. The inner wall of the guide rail 41 is provided with a card slot 42, and the inside of the insertion rod 43 is provided with a card connection assembly 40 that is compatible with the card slot 42.

[0031] The clamping assembly 40 includes a groove 401, a support spring 402 and a clamping block 403. The insert rod 43 is provided with a groove 401 inside, and the support spring 402 is movably sleeved inside the groove 401. Both ends of the support spring 402 are clamped with clamping blocks 403. The end of the clamping block 403 away from the support spring 402 is an arc-shaped end, and one side of the arc-shaped end on the surface of the clamping block 403 is clamped with the clamping groove 42.

[0032] In this embodiment, the two partition bodies 1 are unfolded into the same horizontal plane through the hinge group 2 therebetween, and the insertion rod 43 in the sliding guide rail 41 is used to make one end of the insertion rod 43 pass through the slot 3 in the partition body 1. The two insertion rods 43 have a strong supporting effect. When the insertion rod 43 slides in the guide rail 41, the block 403 on the surface of the insertion rod 43 is squeezed by the inner wall of the guide rail 41, and the block 403 squeezes the support spring 402 in the groove 401 until the arc-shaped end of the surface of the block 403 is inserted into the groove 42 of the inner wall of the guide rail 41, thereby limiting the insertion rod 43, wherein one end of the block 403 is set to an arc-shaped end, which is conducive to the sliding adjustment of the insertion rod 43 in the guide rail 41.

[0033] A telescopic rod 5 is installed between the two clamping blocks 403, and the surface of the telescopic rod 5 is movably sleeved with the inner part of the supporting spring 402;

[0034] Specifically, the telescopic rod 5 is disposed inside the support spring 402 to prevent the support spring 402 from being deformed and becoming unusable.

[0035] The inner wall of the guide rail 41 is provided with a guide groove 6, which is matched with the arc-shaped end of the surface of the clamping block 403;

[0036] Furthermore, a guide groove 6 is provided on the inner wall of the guide rail 41, and the guide groove 6 is provided between the two card slots 42. When the insertion rod 43 slides, the card block 403 on the surface of the insertion rod 43 slides in the card slot 42, so that the sliding of the insertion rod 43 is more guided.

[0037] A toggle block 7 is fixedly mounted on the top of the insertion rod 43, and the top of the toggle block 7 passes through the top of the guide rail 41 and extends;

[0038] It is worth noting that by setting the toggle block 7 on the top of the insertion rod 43, when moving the insertion rod 43, it is only necessary to move the toggle block 7, which can drive the insertion rod 43 to slide and adjust in the guide rail 41.

[0039] A connecting plate 8 with a threaded hole 10 is fixedly installed inside the two partition bodies 1, and the two connecting plates 8 are connected by threaded installation with the threaded hole 10 through a limiting bolt 11;

[0040] Furthermore, when the two partition bodies 1 are folded and stored, the connecting plates 8 on the adjacent surfaces of the two partition bodies 1 are staggered, and the threaded holes 10 between the two connecting plates 8 are at the same level. The limiting bolts 11 are threadedly installed with the two threaded holes 10, so that the folded partition bodies 1 can be fixed to avoid the separation of the two partition bodies 1 and the inconvenience in transportation.

[0041] In order to facilitate the handling of the stored partition body 1 , a groove 9 is provided inside the two partition bodies 1 .

[0042] The two partition bodies 1 of the device are unfolded to the same horizontal plane through the hinge group 2 therebetween, and the insertion rod 43 in the sliding guide rail 41 is made to allow one end of the insertion rod 43 to pass through the slot 3 in the partition body 1. The two insertion rods 43 play a strong supporting effect. When the insertion rod 43 slides in the guide rail 41, the block 403 on the surface of the insertion rod 43 is squeezed by the inner wall of the guide rail 41, and the block 403 squeezes the support spring 402 in the groove 401 until the arc-shaped end of the surface of the block 403 is inserted into the inner wall of the guide rail 41. The card slot 42 is used to limit the insertion rod 43, wherein one end of the card block 403 is set as an arc-shaped end, which is conducive to the sliding adjustment of the insertion rod 43 in the guide rail 41. When the two partition bodies 1 are folded and stored, the connecting plates 8 on the adjacent surfaces of the two partition bodies 1 are staggered, and the threaded holes 10 between the two connecting plates 8 are at the same level. The limiting bolt 11 is threadedly installed with the two threaded holes 10, so that the folded partition body 1 can be fixed to avoid the separation of the two partition bodies 1, which is inconvenient to carry.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
