DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0017] Example: Figure 1-4As shown, the utility model provides a foldable luggage rack, including a fixing frame 2, a first screw rod 23 is rotatably mounted in the middle of the fixing frame 2, a first fixing plate 3 is threadedly mounted on the outer surface of the first screw rod 23, two symmetrically distributed second fixing blocks 36 are fixedly mounted on the lower part of one side of the first fixing plate 3, a rotating shaft 41 is rotatably mounted in the middle of the two second fixing blocks 36, one end of the rotating shaft 41 passes through the second fixing block 36, a worm gear 32 is fixedly mounted on one end of the rotating shaft 41 passing through the second fixing block 36, a second fixing plate 4 is fixedly mounted on the outer surface of the rotating shaft 41, and the first fixing block 33 is fixedly mounted on the lower part of one side of the first fixing plate 3. A worm 34 is rotatably installed in the middle of the first fixed block 33, and the worm 34 is meshed with the worm wheel 32. A plurality of symmetrically distributed first fixed rods 42 are fixedly installed on one side of the second fixed plate 4, and a second fixed rod 43 is provided on one side of the plurality of first fixed rods 42. A third fixed plate 5 is fixedly installed on one side of the plurality of second fixed rods 43. By arranging the worm wheel 34 and the worm 32, the worm wheel 34 and the worm 32 have a self-locking function. When the first fixed rod 42 and the second fixed rod 43 are located horizontally or vertically, the first fixed rod 42 and the second fixed rod 43 are limited by the self-locking of the worm wheel 34 and the worm 32 to avoid movement.
[0018] A third fixing rod 53 is fixedly mounted in the middle of one side of the second fixing plate 4 , a second screw rod 51 is threadedly mounted in the middle of one side of the third fixing rod 53 , and one side of the second screw rod 51 passes through the third fixing plate 5 .
[0019] A symmetrically distributed slide groove 21 is provided in the middle of the fixing frame 2, and two symmetrically distributed sliders 31 are fixedly installed on one side of the first fixing plate 3. The two sliders 31 are slidably clamped in the inside of the slide groove 21. By setting the slide groove 21, the slider 31 is limited by the slide groove 21, that is, the first fixing plate 3 is limited, so that when the first screw rod 23 rotates, the first fixing plate 3 threadedly installed on the outer surface of the first screw rod 23 can be driven to move up and down.
[0020] A limit rod 22 is fixedly installed inside the slide groove 21, and both limit rods 22 slide through the middle of the slider 31. By setting the limit rod 22, the limit rod 22 limits the slider 31, making it more stable when the first screw rod 23 rotates and drives the first fixed plate 3 to move up and down.
[0021] The upper part of the worm 34 passes through the first fixed block 33, and a first handle 35 is fixedly installed on the top of the worm 34. By setting the first handle 35 and rotating the first handle 35, the worm 34 and the worm wheel 32 are driven to rotate, that is, the rotating shaft 41 is driven to rotate, thereby driving the second fixed plate 4 to rotate, so as to facilitate the folding of its structure.
[0022] Two symmetrically distributed mounting plates 1 are fixedly mounted on one side of the fixing frame 2 away from the first fixing plate 3. By setting the mounting plates 1 and mounting the mounting plates 1 at the rear of the vehicle, the luggage rack for placing luggage is fixed.
[0023] A slot 421 is provided in the middle of the plurality of first fixing rods 42, and the plurality of second fixing rods 43 are slidably mounted inside the slot 421. By setting the slot 421 and sliding the second fixing rod 43 inside the slot 421, the length of the second fixing rod 43 can be conveniently adjusted.
[0024] The second screw rod 51 passes through one end of the third fixing plate 5 and is fixedly mounted with a second handle 52 . By setting the second handle 52 and rotating the second handle 52 , the second screw rod 51 is driven to rotate, thereby driving the third fixing plate 5 to move, thereby adjusting the length of the second fixing rod 43 .
[0025] Working principle: In actual use, by rotating the first handle 35, the worm 34 is driven to rotate, so that the meshing worm wheel 32 is rotated, that is, the rotating shaft 41 is driven to rotate, thereby driving the second fixing plate 4 to rotate. After the second fixing plate 4 is driven to rotate ninety degrees, one side of the second fixing plate 4 can be brought into contact with one side of the first fixing plate 3, that is, the second fixing plate 4 is limited. Under the mutual cooperation of the worm wheel 32 and the worm 34 with a self-locking function, it is more stable to place luggage on the upper part of the first fixing rod 42 and the second fixing rod 43. When folding, the first handle 35 can be rotated in the opposite direction. By rotating the first screw rod 23, the first fixing plate 3 can be driven to move up and down, that is, the second fixing plate 4 can be driven to move up and down, thereby adjusting the height of the first fixing rod 42 and the second fixing rod 43 for placing luggage;
[0026] By rotating the second handle 52, the second screw rod 51 is driven to rotate. Since the second screw rod 51 is threadedly installed in the middle of the third fixing rod 53, the third fixing plate 5 is driven to move under the rotation of the second screw rod 51, thereby driving the multiple second fixing rods 43 to move, that is, adjusting the length of the second fixing rod 43 for placing luggage.
[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
