Description

[Technical field]

[0001] The invention relates to an auxiliary supporting structure. [Background technology]

[0002] At present, two-wheeled children's bicycles for younger children on the market generally have an auxiliary support structure. When children are just learning to ride, the auxiliary support structure is connected to the bicycle frame, and the bicycle can have three wheels on the ground, so that the children will not tip over when riding. When children are more proficient in riding skills and want to train their balance, the auxiliary support structure is removed from the bicycle frame, and the bicycle can be ridden as a balance bicycle with the front and rear wheels on the ground. Therefore, when children use the bicycle, they need to frequently disassemble or install the auxiliary support structure, and since the auxiliary support structure is generally connected to the bicycle frame by screws, disassembly and assembly is inconvenient, time-consuming and labor-intensive.

[0003] Therefore, the present invention is just produced based on the above shortcomings. [Summary of the invention]

[0027] The present invention will be further described below in conjunction with the accompanying drawings:

[0028] like Figures 1 to 5 As shown, an auxiliary support structure includes a support seat 1 that can be connected to a frame 100, the support seat 1 is connected to a support rod 2, the support seat 1 is provided with a slot 11 for the end of the support rod 2 to be snapped into, a locking assembly 3 is provided between the support seat 1 and the support rod 2, and the two can be locked when the support rod 2 is snapped into the support seat 1, the locking assembly 3 includes a locking position 31 arranged on the support rod 2, the support seat 1 is provided with a movable part 32 that can move relative to the movable part 32, the top of the movable part 32 is provided with a snap-in portion 321 that can be snapped into the locking position 31, and an elastic part 33 is provided between the movable part 32 and the support seat 1, which can keep the snap-in portion 321 snapped into the locking position 31.

[0029] In actual use, the auxiliary support structure of the present invention is connected to both the left and right sides of the baby carriage. When the auxiliary support structure needs to be installed, the support rod 2 is aligned with the slot 11 of the support seat 1, and then the support rod 2 is pushed upward so that the snap-fit ​​portion 321 on the movable part 32 can be snapped into the locking position 31 on the support rod 2. At this time, the support rod 2 can be locked on the support seat 1. When the support rod 2 needs to be removed, the movable part 32 is pressed so that the snap-fit ​​portion 321 is disengaged from the locking position 31. The user pulls the support rod 2 downward to pull the support rod 2 out of the support seat 1, and disassembly and assembly are very convenient.

[0030] Of course, in one embodiment, a wheel is connected to one end of the support rod 2. It is conceivable that in another embodiment, the other end of the support rod 2 can also be a rotatable foot support.

[0031] like Figure 4 As shown, the locking position 31 is a plug-in slot provided on the support rod 2 and capable of being inserted into the clamping portion 321 , and at the same time, the top surface of the plug-in slot can abut against the clamping portion 321 to prevent the support rod 2 from being separated from the support seat 1 , and the locking is stable.

[0032] like Figures 2 to 3 As shown, the support seat 1 includes a connecting plate 12, a connecting block 13 and a shell 14 which are connected to each other. The connecting plate 12, the connecting block 13 and the shell 14 are connected in sequence, and the connecting plate 12, the connecting block 13 and the shell 14 form the card slot 11 for the support rod 2 to be inserted. The connecting plate 12, the connecting block 13 and the shell 14 are connected and fixed by a quick connection assembly such as a screw assembly, and the connection and installation are convenient.

[0033] like Figure 5 As shown, the connecting plate 12, the connecting block 13 and the housing 14 are provided with connecting holes 15 that can be connected to the frame 100. This setting makes it easy for the three to be on the same axis, which is convenient for positioning and installation, and can be more stable when connected to the frame 100.

[0034] like Figures 2 to 3 As shown, the connection block 13 is provided with a protruding protrusion 131, the connection hole 15 passes through the protruding protrusion 131 and the connection block 13, and the support rod 2 is provided with a positioning groove 21 into which the protruding protrusion 131 can be inserted. The protruding protrusion 131 is provided for positioning and can cooperate with the positioning groove 21 to prevent the support rod 2 from shaking in the front-rear direction relative to the support seat 1.

[0035] like Figures 2 to 3 As shown, the cross section of the support rod 2 is in a U-shaped configuration, which enables the support rod 2 to be more stable when it is clamped and fixed to the support seat 1, and the support rod 2 has high structural strength and is not easy to deform.

[0036] like Figure 3 As shown, the connecting plate 12 is provided with a groove 121, and the connecting block 13 is provided with a clamping protrusion 132 that can be clamped into the groove 121, and when the connecting plate 12 and the connecting block 13 are clamped and fixed, the rear side surface 133 of the connecting block 13 is flush with the back surface 122 of the connecting plate 12. The rear side surface 133 of the connecting block 13 is flush with the back surface 122 of the connecting plate 12. Such an arrangement can make the volume of the two smaller when connected, and the connection between the two is tighter and more stable.

[0037] like Figures 2 to 3 As shown, the movable member 32 is rotatably connected to the connecting block 13, and the connecting block 13 is also provided with an activity space 134 in which the movable member 32 can rotate. The provision of the activity space 134 can facilitate the rotation of the movable member 32.

[0038] like Figures 2 to 3 As shown, two protruding positioning portions 141 are further provided on both sides of the shell 14, and a snap-in groove 123 is provided on the connecting plate 12 for the connecting portion 323 to be snapped into. The length of one of the positioning portions 141 is longer than that of the other positioning portion 141. This arrangement enables the longer positioning portion 141 to be snapped into the frame 100, which is convenient for positioning and installation.

[0039] like Figures 2 to 3 As shown, the housing 14 is also provided with a supporting portion 142 which protrudes downward and can be pressed against the support rod 2. The setting of the supporting portion 142 can prevent the support rod 2 from shaking relative to the support seat 1 in the left and right directions of the frame 100, and the support is more stable.

[0040] like Figures 2 to 3 As shown, the movable part 32 includes a strip-shaped body 322 rotatably connected to the connecting block 13 through a pin shaft, and a protruding clamping portion 321 is connected to the strip-shaped body 322. The lower end of the strip-shaped body 322 is connected to a twisted connecting portion 323 and a pressing piece 324. The strip-shaped body 322 is vertically arranged, and the connecting portion 323 makes the pressing piece 324 twisted 90° relative to the strip-shaped body 322. This arrangement makes the pressing piece 324 horizontally arranged. This design can facilitate the user to perform the pressing operation.

[0041] like Figures 6 to 10 As shown, in another embodiment, the movable member 32 includes a plate-shaped body 325, and the two ends of the plate-shaped body 325 are connected to the rotating parts 3251, and the connecting block 13 is provided with a rotating space 135 in which the rotating part 3251 can move, and the connecting block 13 is also provided with a guide groove 136 that can communicate with the rotating space 135 and guide the rotating part 3251 to enter the rotating space 135, and the top of the plate-shaped body 325 is connected to the clamping part 321, and the lower end of the plate-shaped body 325 is connected to the pressing part 326. The setting of the guide groove 136 facilitates the connection of the plate-shaped body 325 to the connecting block 13 through the rotating part 3251.

[0042] The present embodiment is described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiment, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the present purpose.
