The first end of the supporting rocker arm 12 is rotatably connected, and a rack 18 and a slider locking assembly 17 are arranged inside the side seat 4 on the side corresponding to the supporting rocker arm 12. A thrust gas spring 15 is horizontally installed in the middle part of the side seat 4. The protruding end of the thrust gas spring 15 is connected to the slider locking assembly 17 to push the slider locking assembly 17 to slide along the length direction of the rack 18. By arranging the slider locking assembly 17 and the thrust gas spring 15 on the side seat 4, the structure of the thrust gas spring 15 is simplified and the structure is more reasonable. The slider locking assembly 17 and the thrust gas spring 15 are not easily damaged by collision and are easy to operate. The slider locking assembly 17 has a relatively long stroke and the rotation angle of the wheel locking rod 11 is larger.

[0026] Specifically, when in use, the slider locking assembly 17 needs to be unlocked, and then the thrust gas spring 15 will push the slider locking assembly 17 to move along the rack 18, so that the wheel locking rod 11 can be rotated around the rotating shaft 16 by moving the second end of the supporting rocker arm 12. After the wheel locking rod 11 is rotated to a suitable angle, the slider locking assembly 17 cooperates with the rack 18 to lock, and the bicycle is placed on the support plate 2, and then the position of the wheel bracket 13 is adjusted to tighten the wheel of the bicycle.

[0027] like Figure 2 As shown, the support rocker arms 12 of the two wheel fixing assemblies 1 are installed on the same side, and the thrust gas springs 15 are installed side by side up and down inside the side seat 4 on the same side. The structure is compact, so that the slider locking assembly 17 can be operated on the same side.

[0028] The fixing module in this embodiment can be installed on various bicycle frames, such as a roof frame or a bicycle frame installed at the rear or side of the vehicle. Figure 7 As shown, multiple fixing modules can be installed side by side to install and fix multiple bicycles.

[0029] In this embodiment, as a specific structure of the slider locking assembly 17, as shown in FIG. Figure 6 As shown, the slider locking assembly 17 includes a slider body 176 and an operating wrench 171, the slider body 176 is rotatably connected to the second end of the support rocker arm 12, one end of the operating wrench 171 is connected to an unlocking rod 173, one end of the unlocking rod 173 is connected to the slider body 176 through a first rotating pin 174, a locking movable rod 175 is installed on the side of the slider body 176 close to the rack 18, the middle part of the locking movable rod 175 is connected to the slider body 176 through a second rotating shaft pin 178, the outer side of the second rotating shaft pin 178 is installed with a first coil spring, and the first end of the locking movable rod 175 is extended to the side of the unlocking rod 173 The pressed unlocking end 1751, the second end of the locking movable rod 175 is extended to the latching tooth portion 1752 matching the rack 18, and when the unlocking rod 173 rotates toward the locking movable rod 175, the pressed unlocking end 1751 is pressed downward, so that the latching tooth portion 1752 is disengaged from the rack 18. Under the action of the first coil spring, the latching tooth portion 1752 always has downward power, so the unlocking state can only be maintained if the unlocking rod 173 is kept in a pressed state. A plurality of convex teeth matching the rack 18 are provided on the lower end surface of the latching tooth portion 1752, so that slippage will not occur in the locked state, the installation is reliable, the operation is simple, it is not easy to get stuck, and locking can be achieved at any position.

[0030] At the same time, if Figure 4 and6 As shown, a limiting buckle plate 172 is provided on one side of the unlocking rod 173, and the first end of the limiting buckle plate 172 is rotatably connected to the operating wrench 171 through a third rotating pin 179, and the second end of the limiting buckle plate 172 is provided with a bent end 1722 that extends into the slider body 176 and is buckled with the slider body 176.

When the operating wrench 171 is pressed to rotate the unlocking rod 173 toward the locking movable rod 175, the positioning protrusion 1721 and the slider body 176 are engaged and limited, so that the locking tooth portion 1752 remains disengaged from the rack 18, and the operating wrench 171 can be kept in a pressed state. In this way, the operator can directly hold the wheel locking rod 11 with one hand and rotate it to adjust it. After adjusting to the required angle, the operating wrench 171 is bent outward to disengage the positioning protrusion 1721 from the slider body 176, thereby achieving the locking of the slider locking assembly 17.

[0032] In this embodiment, if Figure 2 As shown, a guide groove 41 is opened on the side wall of the side seat 4 along the length direction, the operating wrench 171 is located on the outside of the side seat 4, the unlocking rod 173, the limiting buckle plate 172 and the second end of the supporting rocker arm 12 are all connected to the slider body 176 through the guide groove 41, and the guide groove 41 can guide the sliding of the slider locking assembly 17, and it is not easy to get stuck.

The lower end plane of the step portion 1731 is in contact with the arc-shaped protrusion, so that the unlocking rod 173 can always maintain linear contact with the downward-pushing unlocking end 1751 when rotating.

[0034] In this embodiment, if Figure 2 and 5As shown, a buffer seat 19 is installed at one end of the side seat 4 away from the thrust gas spring 15, and a buffer spring 20 is installed on the inner side of the buffer seat 19. The buffer spring 20 is connected to a buffer block 14 at one end facing the slider locking assembly 17. The thrust gas spring 15 pushes the slider locking assembly 17 to resist the buffer block 14, thereby compressing the buffer spring 20, thereby playing a buffering role and preventing abnormal noise. At the same time, if the wheel size is too large and exceeds the stroke of the thrust gas spring 15, the wheel locking rod 11 can continue to rotate outward to compress the buffer spring 20 and provide the wheel locking rod 11 with a force to clamp the wheel.

[0035] In order to facilitate the adjustment of the position of the wheel bracket 13, Figure 2 and 3 As shown, a pair of unlocking slide buttons 132 are arranged opposite to each other on the upper side of the wheel support 13, and a positioning pin 134 is arranged at the outward end of the unlocking slide button 132. A plug-in hole 131 matching the positioning pin 134 is arranged on the inner side wall of the wheel locking rod 11 along the length direction. The position of the wheel support 13 can be adjusted by plugging the positioning pin 134 into different plug-in holes 131, so as to adapt to the clamping of wheels with different diameters.
