Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

1-8, the present invention provides a technical solution: a retractable and foldable rack, comprising two first support rods 1 and two second support rods 2, one of the two second support rods 2 There are three equidistantly-distributed rotating shafts 13 between them. The rotating shafts 13 can be used to rotate the storage board 4, so as to facilitate people to fold the storage rack, thereby reducing the occupied space and being convenient for people to use. The outer side is fixedly connected with a storage board 4, the storage board 4 can be used to place items, and three equidistantly distributed horizontal bars 8 are fixedly connected between the two first support bars 1, and the horizontal bars 8 can be used to support the storage board 4. , the inner sides of the two second support rods 2 are symmetrically provided with two T-shaped grooves 18, the inner of the T-shaped grooves 18 is slidably connected with a T-shaped block 16, and one side of the T-shaped block 16 is hinged with a reinforcing rod 3. By setting The T-shaped slot 18, the reinforcing rod 3 and the T-shaped block 16 can make the structure of the rack more firm. One end of the reinforcing rod 3 is hinged with the first support rod 1, and one side of the T-shaped block 16 is fixedly connected with a fixed plate 17. The inside of the plate 17 is threadedly connected with bolts 14 , and the T-block 16 can be fixed by the provided bolts 14 and the fixing plate 17 to prevent the T-block 16 from moving at will.

The interiors of the two first support rods 1 are slidably connected with three sliding rods 12 , one end of the sliding rods 12 is fixedly connected with a clamping block 10 , and a spring 11 is sleeved on the outer side of the sliding rods 12 . Block 10, so that the block 10 can be automatically snapped into the card slot 9, through the interior of the storage board 4 is provided with a card slot 9 that cooperates with the card block 10. fixed to make it stronger.

A disk 7 is fixedly connected to one end of the sliding rod 12 away from the clamping block 10 , and the circular disk 7 can facilitate people to pull the sliding rod 12 to move the clamping block 10 .

Wherein, the bottoms of the two first support rods 1 and the two second support rods 2 are fixedly connected with bottom legs 5, and the bottom legs 5 are threadedly connected with threaded rods 15. The provided threaded rods 15 and bottom legs 5 can To adjust the height of the rack, the bottom of the threaded rod 15 is fixedly connected with a circular bottom pad 6, which can provide support for the entire rack to make it more stable.

Wherein, the top of the clamping block 10 is an inclined surface structure, and the inclined surface structure can facilitate the storage board 4 to press the clamping block 10 to make it move.

Specifically, when it needs to be folded, turn the bolt 14 so that the bolt 14 is not pressed against the second support rod 2, so that the T-shaped block 16 can slide in the T-shaped groove 18, and the sliding rod 12 is pulled by the disc 7, and the sliding rod 12 drives the The clamping block 10 moves, the clamping block 10 is separated from the clamping slot 9, and then the storage board 4 can be rotated upward. After the storage board 4 is rotated, the first support rod 1 is pushed toward the second support rod 2 to complete the folding. When unfolding, pull the first support rod 1 away from the second support rod 2, and then rotate the storage board 4 until the storage board 4 is blocked by the cross bar 8 and cannot move. The block 10 moves to the inside of the first support rod 1, and the block 10 compresses the spring 11. When the block 10 is aligned with the groove 9, the spring 11 resets, so that the block 10 is stuck into the groove 9, and the opposite object can be completed. For the fixing of the plate 4, when the height of the rack needs to be adjusted, the circular bottom pad 6 is rotated, and the circular bottom pad 6 drives the threaded rod 15 to rotate, and the threaded rod 15 is rotated to make the four threaded rods 15 rotate out of the same distance. You can complete the adjustment of the height of the shelf.
