[0027] Please see Figure 1-6 This utility model provides a technical solution: a convenient motorcycle tail rack, including a tail rack 1, a mounting base 11 disposed at the rear end of the tail rack 1, and a backrest pad 2 disposed above the mounting base 11. The feature is that: a positioning cylinder 12 is fixedly disposed in the middle part of the mounting base 11, and fixing cylinders 13 are fixedly disposed on both sides of the mounting base 11. Two connecting posts 21 are fixedly disposed at the bottom of the backrest pad 2. The bottom ends of the two connecting posts 21 are respectively inserted into the two fixing cylinders 13 through the mounting base 11. A fixing component 4 for fixing the connecting posts 21 is disposed inside the mounting base 11, and a rotating component 3 for pulling the fixing component 4 to release is disposed at the top of the mounting base 11.

[0028] The fixing assembly 4 includes a rotating head 31 rotatably mounted on the top of the mounting base 11, a rotating rod 32 vertically fixed at the bottom of the rotating head 31, and a winding disc 33 fixedly sleeved on the middle part of the outer wall of the rotating rod 32 and located inside the positioning cylinder 12.

[0029] The bottom end of the rotating rod 32 is limited to rotating in the middle part inside the positioning cylinder 12;

[0030] The fixing component 4 includes two fixing rods 41 that limit the movement inside the mounting base 11, a return spring 42 that is sleeved on the outer wall of one end of the fixing rod 41 and limited inside the positioning cylinder 12, and a soft steel rope 43 that is fixedly installed at one end of the fixing rod 41 and connected to the winding reel 33.

[0031] The other ends of the two fixing rods 41 are respectively inserted into the interior of the connecting column 21 through the fixing cylinder 13;

[0032] By rotating the rotating head 31, the winding reel 33 located inside the positioning cylinder 12 rotates, causing the soft steel ropes 43 connected to both sides of the winding reel 33 to wind into the winding cavity of the winding reel 33. At the same time, one end of each soft steel rope 43 pulls the two fixed rods 41 connected to it to move into the positioning cylinder 12. Simultaneously, the large end of the fixed rod 41 pushes the return spring 42 to press against the outer wall of the positioning cylinder 12. When one end of the fixed rod 41 disengages from the inside of the connecting column 21, the backrest cushion 2 can be pulled upwards, causing the connecting column 21 to disengage from the inside of the fixing cylinder 13 and the mounting base 11. Compared to the previous bolt disassembly time of several minutes, this disassembly method only takes a few seconds, which is faster and more convenient. At the same time, no tools are required for disassembly, and the backrest cushion 2 can be disassembled anytime and anywhere.

[0033] In a further preferred embodiment, two notches 121 are provided on both sides of the outer wall of the positioning cylinder 12, which are opposite to one end of the fixing rod 41. The inner side of the notch 121 is arc-shaped. A winding groove is provided in the middle part of the outer wall of the winding reel 33. Two rings 321 are provided in the edge groove of the winding reel 33. One end of the soft steel rope 43 is fixedly connected to the ring 321 through the notch 121.

[0034] The notches 121 on both sides of the outer wall of the positioning cylinder 12 are opposite to the small end of the fixing rod 41. The soft steel rope 43, which is connected to the small end of the fixing rod 41, passes through the positioning cylinder 12 and connects to the winding reel 33. The inner side of the notch 121 is arc-shaped to reduce the friction between the soft steel rope 43 and the notch 121 when it is wound onto the winding reel 33, thereby improving the service life of the soft steel rope 43.

[0035] More preferably, the upper ends of the two fixed cylinders 13 are respectively connected to the top of the mounting base 11, and a round hole for mounting the rotating rod 32 is opened in the middle part of the top of the mounting base 11.

[0036] The upper end of the fixed cylinder 13 communicates with the top of the mounting base 11, and the connecting column 21 is inserted into the fixed cylinder 13 through the top of the mounting base 11.

[0037] More preferably, the mounting base 11 is provided with a limiting cavity 111 that matches the fixing rod 41. The fixing rod 41 moves inside the limiting cavity 111. The outer wall of the fixing cylinder 13 is provided with a through-hole symmetrical to one end of the fixing rod 41. The outer wall of the connecting column 21 is provided with a fixing hole opposite to one end of the fixing rod 41. One end of the fixing rod 41 is inserted into the fixing hole through the through-hole.

[0038] The limiting cavity 111 provided inside the mounting base 11, which matches the fixing rod 41, is used to limit the tilting movement of the fixing rod 41 inside the mounting base 11. The opening provided on the outer wall of the fixing cylinder 13 is used for one end of the fixing rod 41 to pass through and be inserted into the fixing hole opened on the outer wall of the connecting column 21, thereby fixing the connecting column 21 inserted inside the fixing cylinder 13. When the connecting column 21 is inserted into the fixing cylinder 13, the fixing hole is opposite to the opening and one end of the fixing rod 41.

[0039] More preferably, a rotation limiting cylinder 122 is provided in the middle part of the positioning cylinder 12, the bottom end of the rotating rod 32 is a ring shape protruding outward, and a rotation groove matching the bottom end of the rotating rod 32 is opened inside the rotation limiting cylinder 122, so that the bottom end of the rotating rod 32 can rotate inside the rotation limiting cylinder 122.

[0040] The bottom of the rotating rod 32 is a disc with an outward protrusion and a diameter larger than the whole. The rotating rod 32 is constrained by the rotating limiting cylinder 122 set inside the positioning cylinder 12, and the rotating limiting cylinder 122 has a rotating groove that matches the bottom end of the rotating rod 32.

[0041] Preferably, the diameter of the notch 121 is smaller than the diameter of one end of the return spring 42.

[0042] More preferably, the diameter of one end of the fixing rod 41 is larger than the diameter of the other end, the return spring 42 is sleeved on the small end of the fixing rod 41, and the diameter of the large end of the fixing rod 41 is larger than the diameter of the other end of the return spring 42.

[0043] With one end of the fixed rod 41 being the large end and the other end being the small end, a return spring 42 is fitted onto the small end. When the fixed rod 41 moves toward the positioning cylinder 12, the large end of the fixed rod 41 pushes the return spring 42 to move. Since the diameter of the other end of the return spring 42 is smaller than the notch 121, the return spring 42 is pressed against the diameter of the large end of the fixed rod 41 in the positioning cylinder 12.

[0044] One specific application of this embodiment is as follows: During installation, the rotating head 31 is rotated in any direction, causing the two soft steel ropes 43 to wind around the two sides of the winding reel 33 respectively. One end of the fixed rod 41 is connected through the soft steel rope 43, and the two fixed rods 41 are pulled towards the positioning cylinder 12, so that the other end of the fixed rod 41 is disengaged from the hole of the fixed cylinder 13, exposing the entire hole of the fixed cylinder 13. Then, the two connecting posts 21 at the bottom of the backrest cushion 2 can be inserted into the fixed cylinder 13. When the bottom end of the connecting post 21 cannot move from the bottom of the fixed cylinder 13, the fixing hole of the connecting post 21 is aligned with the through opening and the large end of the fixed rod 41. The rotating head 31 is released, and the fixed rod 41 is pushed by the compression of the return spring 42 to move to the initial state, and one end is inserted into the inside of the connecting post 21, constraining and fixing the connecting post 21 in the fixed cylinder 13. The backrest cushion 2 is then fixedly installed on the mounting base 11, which facilitates installation.
