DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 2 As shown, a portable shelf trolley comprises: a first frame 1 and a second frame 2. A plurality of support plates 3 are arranged on the first frame 1 and the second frame 2 to form a plurality of placement layers for placing items. A first side angle of a first end of the first frame 1 is hinged to a first side angle of a first end of the second frame 2, so that the two frames can rotate relative to each other.

[0024] Universal wheels 4 are provided at the bottom of the first frame 1 and the bottom of the second frame 2. Preferably, the universal wheels 4 are silent universal wheels with a braking function, and there are four universal wheels 4 at the bottom of the first frame 1, which are distributed at the four corners of the first frame 1. There are four universal wheels 4 at the bottom of the second frame 2, which are distributed at the four corners of the bottom of the second frame 2. The silent universal wheels with a braking function make the trolley less noisy when moving.

[0025] like Figure 1 and Figure 3 As shown, the second end surface of the first frame 1 is provided with two first connecting buckles 5 arranged side by side. A circular through hole is provided on the first connecting buckle 5, and a locking shaft 6 is slidably provided in the circular through hole. A limiting plate 7 is provided on the locking shaft 6, and the limiting plate 7 is arranged between the two first connecting buckles 5, and a limiting through groove 8 is provided on the locking shaft 6. A limiting protrusion 9 is provided on the second end surface of the first frame 1, and the limiting protrusion 9 is adapted to the limiting through groove 8. The limiting protrusion 9 can be inserted into the limiting through groove 8, so that the positions of the locking shaft 6 and the limiting plate 7 are relatively fixed. A first connecting buckle 5 is provided on the second end surface of the second frame 2, and the first connecting buckle 5 is provided corresponding to the locking shaft 6. When the end of the locking shaft 6 is slidably inserted into the first connecting buckle 5 on the second frame 2, the second ends of the two frames can be fixedly connected to prevent the two frames from rotating and separating. Preferably, a lock hole is provided on the limiting protrusion 9, and the limiting plate 7 can be locked by a lock.

[0026] like Figure 2 and Figure 5As shown, two second connecting buckles 11 are provided on the first side surface of the support plate 3 on the second frame 2 near the first end of the second frame 2, and a through hole is provided on the second connecting buckle 11, in which a locking slide bar 12 is slidably provided. Preferably, the cross section of the through hole provided on the second connecting buckle 11 is rectangular, and the cross section of the locking slide bar 12 is rectangular, so that the locking slide bar 12 can only slide but cannot rotate.

[0027] A pulling protrusion 13 is provided on the locking slide bar 12 between the two second connecting buckles 11 so that an operator can pull the locking slide bar 12 to move it.

[0028] A second connection buckle 11 is provided on the first side surface of the support plate 3 on the first frame 1 near the first end of the first frame 1, and the second connection buckle 11 is provided corresponding to the locking slide bar 12. When the end of the locking slide bar 12 is slidably inserted into the second connection buckle 11 on the first frame 1, the two frames are relatively fixedly connected.

[0029] In order to improve the stability of the shelf or cart, a supporting mechanism is provided at the bottom of the first frame 1 and the bottom of the second frame 2.

[0030] like Figure 4 As shown, the support mechanism includes a connection seat 14, a screw rod 15 and a base 16. The connection seat 14 is fixedly arranged at the bottom of the first frame 1 and the second frame 2, and a screw hole is opened on it. The screw rod 15 is threadedly engaged in the screw hole, and the bottom is fixedly connected to the base 16. A hexagonal rotating block 17 is fixedly sleeved on the screw rod 15. Rotating the hexagonal rotating block 17 with a wrench can drive the screw rod 15 and the base 16 to rotate to change the support height.

[0031] Furthermore, to facilitate pushing the cart, a mounting seat 18 is provided on the second end surface of the first frame 1 and the second end surface of the second frame 2, and a polygonal through hole is provided on the mounting seat 18. A handle 19 is slidably fitted in the polygonal through hole. The handle 19 includes a sliding connection part and a gripping part, and the sliding connection part has a polygonal cross section and is slidably fitted in the polygonal through hole. The gripping part has a circular cross section and one end is connected to the sliding connection part. The cooperation of the polygonal through hole and the sliding connection part makes the handle 19 non-rotatable, which is convenient for pushing the cart.

[0032] like Figure 1 As shown, when the two vehicle frames are rotated to be parallel, a cart structure is formed. At this time, the locking shaft rod 6 effected by the second end face of the vehicle frame is fixed.

[0033] like Figure 2 As shown, when the two frames are rotated to two frames side by side, a shelf structure is formed. At this time, fixing is achieved by the locking slide bar 12 effect.

[0034] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
