[0030] As attached Figure 1 To Attachment Figure 8 As shown:

[0031] The utility model provides a detachable trailer bucket for a bicycle, comprising a bucket 1 and a connecting structure connected to the rear wheel of the bicycle, wherein the bottom of the bucket 1 is connected to a support frame 2 by fasteners, so that in actual use, a bucket 1 of a suitable size can be selected according to actual needs and installed with the support frame 2 by connecting with fasteners, which has high convenience in use and is also convenient for disassembly during sales and transportation, thereby reducing the occupied space volume and reducing the transportation cost; shaft sleeves are fixed at both left and right ends of the bottom of the support frame 2, and wheels 12 are installed on the shaft sleeves through shafts; the connecting structure comprises a U-shaped frame 9, and the inner sides of the two ends of the U-shaped frame 9 are connected to the rear wheel of the bicycle The two ends of the center axis of the wheel are connected; a mounting hole is vertically provided at the center of the U-shaped frame 9, and a connecting pin 8 is rotatably installed in the mounting hole. The upper and lower ends of the connecting pin 8 are commonly connected to a connecting seat 7, so that when the bicycle is traveling, the bucket 1 connected to its rear end can be adaptively rotated left and right; one side of the connecting seat 7 is horizontally connected to a universal shaft 6, and the other end of the universal shaft 6 is rotatably connected to a mounting sleeve 5, so that when the bicycle is traveling, the bucket 1 connected to its rear end can be adaptively rotated when the wheels 12 rotate asynchronously or when the left and right roads are uneven; one side of the top of the mounting sleeve 5 is fixedly connected to the bottom of the support frame 2 through a connecting frame 3.

[0032] Among them, the inner sides of both ends of the U-shaped frame 9 are connected with adapter plates 10, and the side surfaces of the adapter plates 10 are sequentially provided with arc grooves 101, connecting holes 102 and connecting holes 2 103; the inner sides of both ends of the U-shaped frame 9 are fixedly installed with two groups of fixing pins 11, and one end of the two groups of fixing pins 11 are respectively installed in the arc groove 101 and the connecting hole 1 102; the connecting hole 2 103 is respectively connected to the two ends of the central axis of the rear wheel of the bicycle, so that during driving, through the action of the arc groove 101 and the connecting hole 1 102, the U-shaped frame 9 and the truck bed 1 can be adaptively adjusted to float up and down.

[0033] The center of the arc groove 101 coincides with the center of the connecting hole 102 ; the width of the arc groove 101 , the inner diameter of the connecting hole 102 , and the outer diameter of the fixing pin 11 are equal.

[0034] Among them, the adapter plate 10 is provided with an opening for hooking into the middle axis of the rear wheel of the bicycle on the bottom side near the second connecting hole 103, so that when it is inconvenient to remove the locking nut at the end of the middle axis of the rear wheel of the bicycle, the locking nut can be loosened and quickly hooked in to ensure convenience of use.

[0035] One end of the fixing pin 11 is provided with a thread, and is connected to a limiting nut through the thread, so as to ensure that the adapter plate 10 has high stability when in use.

[0036] A diagonal brace 4 is obliquely installed on one side of the top of the installation sleeve 5 , and the other end of the diagonal brace 4 is fixedly connected to the side wall of the connecting frame 3 to improve the installation stability of the installation sleeve 5 .

[0037] One end of the universal shaft 6 is fixedly welded to one side of the connecting seat 7 .

[0038] Among them, the left and right sides of the installation sleeve 5 are obliquely fixedly connected with reinforcement tubes 15, and the reinforcement tubes 15 are fixedly connected to the side surfaces of the shaft sleeves at the left and right ends of the bottom of the support frame 2.
