[0006] Two locking holes are provided on each connecting pipe;

[0007] The corresponding connecting rod assemblies on two adjacent universal wheel seats are connected together through a connecting pipe. The connecting rod assembly is inserted into the connecting pipe. The limiting rod on the connecting rod assembly is clearance-matched with the inner wall of the end of the connecting pipe, and the locking block on the connecting rod assembly is stuck in the locking hole of the connecting pipe.

[0008] Preferably, the locking hole is opened on the bottom surface of the connecting pipe.

[0009] Preferably, on each universal wheel seat, the angle between two limit stop bars in the limit stop bar assembly is (n-2)×360°∕n, and the angle between two connecting rod assemblies is (n-2)×360°∕n, where n is the number of universal wheel seats.

[0010] Preferably, the number of the universal wheel seats is 3 to 6. More preferably, the number of the universal wheel seats is 4.

[0011] The utility model has the advantages of simple structure, convenient and quick disassembly and assembly, small occupied area and required space when stored, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model is further described below in conjunction with specific embodiments.

[0017] A quick disassembly and assembly trolley, such as Figure 1 and Figure 2 As shown, it comprises a universal wheel seat 1, a universal wheel 2, a limit stop bar assembly 3, a connecting rod assembly 4 and a connecting pipe 5; the number of the universal wheel seats 1 is more than 3, and the number of the connecting pipes 5 is equal to the number of the universal wheel seats 1;

[0018] A universal wheel 2 is installed at the bottom of each universal wheel seat 1, a limit stop bar assembly 3 is fixed on the top surface of each universal wheel seat 1, each limit stop bar assembly 3 includes two limit stop bars fixed together, and two connecting rod assemblies 4 are fixed on the side of each universal wheel seat 1, each connecting rod assembly 4 includes a fixed integral limit rod 4.1, a spring piece 4.2 and a locking block 4.3;

[0019] Two locking holes 5.1 are provided on each connecting pipe 5;

[0020] like Figure 3 and Figure 4 As shown, the corresponding connecting rod assemblies 4 on two adjacent universal wheel seats 1 are connected together through a connecting tube 5, the connecting rod assembly 4 is inserted into the connecting tube 5, the limiting rod 4.1 on the connecting rod assembly 4 is clearance-matched with the inner wall of the end of the connecting tube 5, and the locking block 4.3 on the connecting rod assembly 4 is inserted into the locking hole 5.1 of the connecting tube 5.

[0021] The locking hole 5 . 1 is formed on the bottom surface of the connecting pipe 5 .

[0022] On each universal wheel seat 1, the angle between two limit stop bars in the limit stop bar assembly 3 is (n-2)×360°∕n, and the angle between two connecting rod assemblies 4 is (n-2)×360°∕n, where n is the number of universal wheel seats 1.

[0023] The number of the universal wheel seats 1 is 3-6, and the number of the universal wheel seats 1 is preferably 4.

[0024] The corresponding connecting rod assemblies 4 on two adjacent universal wheel seats 1 are connected together through a connecting tube 5, the connecting rod assembly 4 is inserted into the connecting tube 5, the limiting rod 4.1 on the connecting rod assembly 4 is clearance-matched with the inner wall of the end of the connecting tube 5, and the locking block 4.3 on the connecting rod assembly 4 is inserted into the locking hole 5.1 of the connecting tube 5, and the assembly work of the utility model can be completed. The limiting stop bar assembly 3 on the top surface of each universal wheel seat 1 can prevent the dining utensils (such as baking trays) from slipping out.

[0025] When disassembling, the utility model is turned over, the locking block 4.3 is pressed down and the universal wheel seat 1 is pulled outward, so that the connecting rod assembly 4 and the connecting pipe 5 on the universal wheel seat 1 can be separated. According to this method, all the connecting rod assemblies 4 and the connecting pipes 5 are separated, and the universal wheel seat 1 is neatly stacked, which can greatly reduce the floor space and the required space during storage.

[0026] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
