[0041] In the embodiment, the plurality of support legs 2 of the support unit are rotationally connected to the mounting piece 1 through the connecting rods, not only in the use state, the auxiliary rods 4 are rotated towards the direction away from the main rod 3 and the plurality of support legs 2 are driven to be away from each other, so that the support area of the support unit is increased, and the support unit can be stably placed on the ground; and in the storage state, the auxiliary rods 4 are rotated towards the main rod 3, so that the plurality of connecting rods are close to each other, and the plurality of support legs 2 are also close to each other, and the space between the rod members of the support unit in the storage state is reduced, so that the length and width of the support unit are greatly reduced, the packaging space is avoided to be wasted, and the cost of packaging and transportation is saved.

[0042] Preferably, three connecting rods are arranged on the mounting piece 1, that is, one main rod 3 and two auxiliary rods 4 are connected to the mounting piece 1, and the three connecting rods are connected to the peripheral side of the mounting piece 1 at the same interval, so that in the use state, the included angle between the three connecting rods is close to 120°, not only the support area formed between the support legs 2 is large, and the support stability is good, but also the number of connecting rods used is small, so that the structure of the support unit is simple, and the manufacturing cost is low.

Of course, in other embodiments of the application, the number of connecting rods on the mounting piece 1 can also be four, five, six and the like.

[0043] Please refer to the accompanying drawings Figure 4In some embodiments of the present application, the main rod 3 is provided with a sliding piece 310, and a sliding groove 311 is hollowed out in the front and rear directions on the sliding piece 310, and the sliding piece 310 is slidably connected to the main rod 3 through the sliding groove 311. The sliding piece 310 and each auxiliary rod 4 are connected through a transmission rod 410, one end of the transmission rod 410 is hingedly connected to the auxiliary rod 4, and the other end is hingedly connected to the sliding piece 310, so that when the sliding piece 310 slides along the main rod 3, the plurality of auxiliary rods 4 are driven to rotate towards the main rod 3. By forming a linkage slider mechanism between the main rod 3, the auxiliary rod 4, the sliding piece 310 and the transmission rod 410, only the sliding adjustment of the sliding piece 310 is needed to drive all the auxiliary rods 4 to rotate synchronously, and then the use state and the storage state of the support unit are switched, so that the state switching operation of the support unit is more convenient.

[0044] Please refer to the accompanying drawings Figures 11-12 In some embodiments of the present application, the upper side wall of the sliding groove 311 is hollowed out to form an opening 312, and a U-shaped lock catch 320 is further arranged on the sliding piece 310, a region surrounded in the middle of the lock catch 320 forms a clamping area 321, and the left and right ends of the lock catch 320 are rotatably connected to the sliding piece 310. The sliding piece 310 has a lockable state and an unlocked state, in the locked state, the lock catch 320 is rotated downward and is sleeved on the end of the sliding piece 310 through the clamping area 321, the left and right sides of the sliding piece 310 are extruded by the lock catch 320 and are extruded into the opening 312, and then the left and right sides of the main rod 3 are clamped by the side wall of the sliding groove 311, so that the sliding piece 310 and the main rod 3 are relatively fixed; in the unlocked state, the lock catch 320 is rotated upward, the clamping area 321 is separated from the end of the sliding piece 310, so that the sliding piece 310 can slide relative to the main rod 3 again.

[0045] In the present embodiment, in the storage state or the use state, the lock catch 320 is rotated downward to extrude the sliding piece 310, the sliding piece 310 is switched to the locked state, the sliding piece 310 and the main rod 3 are relatively fixed, the main rod 3 and the auxiliary rod 4 are relatively fixed, and the support unit can be stably fixed in the current state; when the state of the support unit needs to be switched, the lock catch 320 is only needed to be rotated upward to avoid the end of the sliding piece 310, the sliding piece 310 is switched to the unlocked state, and the sliding piece 310 can be adjusted again. Not only the stability of the support unit is better, but also the locking and unlocking operations are relatively simple.

[0046] Please refer to the accompanying drawings Figures 11-12In some embodiments of the present application, the sliding member 310 is further rotatably connected with a lock catch 320, and the lock catch 320 and the main rod 3 are connected through a limiting structure, which includes a limiting protrusion 322 and a limiting hole 301. A plurality of limiting holes 301 are provided on the main rod 3 along the length direction, and the limiting protrusion 322 is provided on the lock catch 320 correspondingly. The sliding member 310 has a lockable state and an unlocked state. In the lockable state, the lock catch 320 is rotated downward, the limiting protrusion 322 is clamped into the limiting hole 301, so that the sliding member 310 and the main rod 3 are relatively fixed. In the unlocked state, the lock catch 320 is rotated upward, the limiting protrusion 322 is disengaged from the limiting hole 301, so that the sliding member 310 can slide relative to the main rod 3 again.

[0047] In the present embodiment, only the lock catch 320 needs to be rotated, so that the limiting protrusion 322 is clamped into or disengaged from the limiting hole 301, thereby adjusting the relative fixation or sliding between the sliding member 310 and the main rod 3. This not only further improves the stability of the support unit, but also makes the adjustment operation simple and convenient.

[0048] Preferably, two limiting holes 301 are provided on the main rod 3, corresponding to the positions of the limiting protrusion 322 on the main rod 3 in the use state and the storage state respectively. Through the clamping cooperation between the limiting protrusion 322 and the limiting hole 301, the support unit can be stably fixed in the use state or the storage state.

[0049] Please refer to the accompanying drawings Figures 13-14 The main rod 3 and the auxiliary rod 4 can also have other connection structures. For example, in some embodiments of the present application, the main rod 3 and the auxiliary rod 4 are connected through a hinge structure, which includes a first connecting rod 330 and a second connecting rod 420. One end of the first connecting rod 330 is hingedly connected to the main rod 3, and the other end is hingedly connected to the second connecting rod 420. The end of the second connecting rod 420 away from the first connecting rod 330 is hingedly connected to the auxiliary rod 4. When the support unit is in the use state, the ends of the first connecting rod 330 and the second connecting rod 420 hingedly connected to each other are spread outward, thereby limiting the rotation of the main rod 3 towards the auxiliary rod 4. When the ends of the first connecting rod 330 and the second connecting rod 420 hingedly connected to each other are folded inward, the auxiliary rod 4 can rotate towards the main rod 3 again, and the support unit can be switched to the storage state.

[0050] In the embodiment, the first connecting rod 330, the second connecting rod 420, the main rod 3 and the auxiliary rod 4 are hingedly connected to form a hinge four-bar mechanism, and the second connecting rod 420 is the shortest rod in the four-bar mechanism, so that when the ends of the first connecting rod 330 and the second connecting rod 420 are outwardly spread in the use state, the hinge four-bar mechanism rotates to the limit position, and the auxiliary rod 4 cannot rotate toward the main rod 3 any more, so that the support unit can be kept in the use state and the stability is better; when the support unit needs to be adjusted to the storage state, the ends of the first connecting rod 330 and the second connecting rod 420 outwardly spread only need to be pressed inward, so that the first connecting rod 330 and the second connecting rod 420 are inwardly folded, and the auxiliary rod 4 can be rotated toward the main rod 3 again. Therefore, the hinge structure not only has a simple structure, but also can limit the rotation adjustment of the auxiliary rod 4, so that the stability of the support unit is better.

[0051] Please refer to the accompanying drawings Figure 10 In some embodiments of the present application, a plurality of telescopic members are arranged on the connecting rod, the length of the telescopic member can be extended or shortened, and the telescopic member is configured to support the bottom end of the storage frame 5 and keep the storage frame 5 horizontal.

[0052] In the embodiment, by arranging the telescopic member which can be telescopically adjusted on the connecting rod, when the storage frame 5 is placed on the mounting member 1, the length of the telescopic member can be adjusted to ensure that the top end of the telescopic member abuts against the bottom end of the storage frame 5, so that the storage frame 5 is prevented from tilting, and the stability of the support unit is improved.

[0053] As shown in the accompanying drawings Figure 10 The telescopic member includes an internally threaded pin 411 and a screw 412 screwed on both ends of the internally threaded pin 411, the transmission member 410 and the auxiliary rod 4 are hingedly connected through the internally threaded pin 411, and the screw 412 on both ends of the internally threaded pin 411 is used for fixing in the vertical direction, and the screw 412 at the top end of the internally threaded pin 412 is configured to support the storage frame 5. By screwing the screw 412 on the upper side, the screw 412 is pushed out upward or retracted downward relative to the internally threaded pin 411, so that the length of the telescopic member is adjusted, and the adjustment operation is convenient.

[0054] Please refer to the accompanying drawings Figures 1-5 The embodiment of the present application also provides a storage rack, which comprises a plurality of storage frames 5 and a plurality of support units, the plurality of support units are stacked in the vertical direction, and the support legs 2 of two adjacent support units in the vertical direction are detachably connected through the locking assembly; in the storage state, the two support legs 2 are separated from each other, so that the plurality of support units are separated from each other and can be stored in the storage frame 5.

[0055] In the embodiment, the support units are stacked up and down to form the storage rack, which not only makes the overall structure of the storage rack simple, but also can carry more objects. In the storage state, the storage rack is divided into several support units and can be stored in the storage frame 5, so that the support units and the storage frame 5 do not need to be packaged separately when the storage rack is stored, the overall space utilization is good, the packaging space is greatly saved, and the packaging and transportation cost is further reduced.

[0056] Preferably, the storage rack includes two support units stacked up and down, and the diameter of the storage frame 5 on the lower support unit is larger than that on the upper support unit, so that in the storage state, the smaller storage frame 5 can be stored in the larger storage frame 5, and the folded support unit is accommodated therein, as shown in the accompanying drawings, thereby further reducing the occupied space of the storage rack and the cost of packaging and transportation. Of course, in other embodiments of the present application, the number of support units in the storage rack can also be one, three, four, etc. Figure 5

[0057] The storage rack further includes a handrail 6 configured for a user to push and pull the storage rack.

The handrail 6 is installed at the top end of the uppermost support unit in the storage rack, and the insertion parts 610 and the support leg 2 are inserted and matched, so that the handrail 6 is convenient to install and disassemble.

[0058] Please refer to the accompanying drawings Figure 3 In some embodiments of the present application, the storage frame 5 and the mounting member 1 are detachably connected through a positioning assembly. The positioning assembly includes a positioning groove 110 and a positioning member 510 which are matched with each other. The positioning member 510 is arranged on one of the mounting member 1 and the storage frame 5, and the positioning groove 110 is arranged on the other one. When the storage frame 5 is installed on the mounting member 1, the positioning member 510 is clamped into the positioning groove 110, so that the storage frame 5 and the mounting member 1 are relatively fixed in the horizontal direction.
