[0028] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Example 1

[0030] refer to Figure 1 A multifunctional bicycle rear rack includes a rack base 1, a square fixing tube 2 on the rack base 1, and a square adjusting rod 3 inserted into the fixing tube 2. The insertion structure allows for easy height adjustment. The fixing tube 2 is equipped with a locking component 21 for locking the height position of the adjusting rod 3. The locking component 21 is a hand-tightening screw.

[0031] The fixed tube 2 is equipped with an automatic latch 22, and the adjusting rod 3 has multiple latch holes 31 along the height direction. The automatic latch 22 matches the latch holes 31. The automatic latch 22 serves a positioning function, and its specific structure can be a radially telescopic latch with a spring.

[0032] A U-shaped hanger body 4 is rotatably connected to the top of the adjusting rod 3, and a rotary locking structure is provided between the adjusting rod 3 and the hanger body 4. By rotating the hanger body 4 to change its orientation and locking it using the rotary locking structure, the hanger body 4 has multiple switchable fixed positions. (Reference) Figure 2 The fixed positions include the forward tilt position A of the bracket body 4 facing the front of the rear of the vehicle, the rear tilt position B of the bracket body 4 facing the rear of the vehicle, and the downward tilt position C of the bracket body 4 facing the bottom of the vehicle.

[0033] Specifically, the rotating locking structure includes a rotating sleeve 32, a positioning pin 33, and a fixing screw 34. The rotating sleeve 32 is fixedly connected to the top of the adjusting rod 3, and the bracket body 4 is rotatably connected inside the rotating sleeve 32. The rotating sleeve 32 and the bracket body 4 are provided with corresponding cross pin holes. The positioning pin 33 and the fixing screw 34 are located on the top of the adjusting rod 3 and correspond to the cross pin holes. Limiting rings 41 are provided on both sides of the bracket body 4 located on the rotating sleeve 32 to prevent the bracket body 4 from moving axially.

[0034] refer to Figure 3 , Figure 4 The bracket body 4 is provided with several connection holes. Various accessories can be installed on the bracket body 4 through the connection holes and external connectors (such as clamps): such as rescue shovel 100, rescue sandboard 200, license plate 300, flagpole insert 400, radio antenna, storage frame 500, storage board, etc.

[0035] refer to Figure 5 The adjusting rod 3 can also be used upside down. When upside down, it can be used as a table by installing a rescue sand plate 200 or a placement plate on the hanging frame body 4.

[0036] refer to Figure 6 In one usage state of the multi-functional bicycle rack at the rear of the vehicle in this embodiment, a sand plate mounting bracket 5 is detachably connected to the rack body 4. The sand plate mounting bracket 5 is provided with a sand plate fixing shaft 51, and a shaft locking device 6 is sleeved on the sand plate fixing shaft 51. The rescue sand plate can be inserted into the sand plate fixing shaft 51 and fixed by the shaft locking device 6.

[0037] refer to Figure 7The shaft locking device 6 includes an inner ball bearing 61, an outer ball bearing 62, and a lower pressure cone 63. The inner ball bearing 61 has a handle at its top and multiple radial through holes 611 at its bottom, each containing a pressure ball 64. The outer ball bearing 62 is fitted over the inner ball bearing 61 and has a tapered hole 621 at its bottom. A lower pressure spring 65 is mounted on the inner ball bearing 61, and the lower pressure cone 63 is located below the outer ball bearing 62, containing an upper pressure spring 66 that abuts against the outer ball bearing 62. A safety pin 52 is located at the top of the sand plate fixing shaft 51.

[0038] The principle of the shaft locking device 6 is as follows: When locking, the lower spring 65 extends, ensuring that the bottom of the inner ball bearing 61 is always within the tapered hole 621 at the bottom of the outer ball bearing 62. The pressure ball 64 is pressed inward by the inner wall of the tapered hole 621, tightly pressing the sand plate fixing shaft 51. At the same time, the lower cone 63 contacts the top surface of the rescue sand plate, and the upper spring 66 causes the outer ball bearing 62 to move upward, thereby causing the tapered hole 621 to press the pressure ball 64 more forcefully, increasing the pressure of the pressure ball 64 on the sand plate fixing shaft 51 and achieving locking. When unlocking, pull the handle upward, compress the lower spring 65, and the pressure ball 64 moves away from the tapered hole 621 of the outer ball bearing 62, no longer pressing the sand plate fixing shaft 51, thus allowing the shaft locking device 6 to be removed.

[0039] Example 2

[0040] refer to Figure 8 , Figure 9 The difference between this embodiment and Embodiment 1 is that the rotating locking mechanism includes a rotating sleeve 32, a toothed ring 42, and a locking nut 43. The rotating sleeve 32 is fixedly connected to the top of the adjusting rod 3. One side of the rotating sleeve 32 has teeth 321. The bracket body 4 is rotatably connected inside the rotating sleeve 32. The toothed ring 42 is fixedly connected to the bracket body 4 and faces the teeth 321. A stud 44 is provided on the side of the bracket body 4 opposite to the toothed ring 42, and the locking nut 43 is threadedly connected to the stud 44. By rotating the locking nut 43, the toothed ring 42 and the teeth 321 are tightly engaged, thus fixing the bracket body 4. A pressure ring 45 and an anti-loosening nut 46 are also provided on both sides of the locking nut 43 on the stud 44.

[0041] The fixed tube 2 is movably connected to the bracket 1 and can be adjusted forward and backward. Specifically, a sliding plate 23 is fixedly connected to the bottom of the fixed tube 2. The sliding plate 23 and the bracket 1 are provided with multiple connecting holes. The forward and backward position of the fixed tube 2 can be adjusted by connecting the connecting holes at different positions with nuts.

[0042] Example 3

[0043] refer to Figure 10The difference between this embodiment and embodiment 1 is that the bracket body 4 is fixedly connected to the adjusting rod 3 in an L-shape, and the front and back of the adjusting rod 3 can be inserted into the fixing tube 2. The bracket body 4 can be switched between the forward and backward positions by inserting it in the forward or reverse direction.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
