Description

Carrying frame folding positioning structure and carrying frame including the same

The invention relates to a folding and positioning structure for a carrying frame and a carrying frame including the same.

By the way, modern people like to engage in outdoor leisure activities to relax while on vacation. Therefore, in recent years, it is popular to place bicycles on the bicycle carrier frame for connection with the body of the car. The conventional carrier frame has a fixed rod. One end is pivotally connected to a connecting rod connecting the car body, and the other end is provided with a supporting rod extending in the direction of the lateral fixed rod. The supporting rod is used to install and position the bicycle. Because the fixed rod and the connecting rod of the conventional carriage frame There is a pivotal connection between them, so a snapping structure is required to prevent the fixed rod and the connecting rod from swinging freely. However, the snapping structure of the conventional carrying frame is easy to jump when the car is traveling, causing the snapping structure to loosen. This will cause the fixed rod and the connecting rod to oscillate randomly, causing the bicycle to fall. There are shortcomings that need to be improved. Cons.

Therefore, it is necessary to provide a novel and progressive folding and positioning structure for the carrying frame and the carrying frame including the same to solve the above-mentioned problems.

The main purpose of the present invention is to provide a folding and positioning structure for a carrying frame and a carrying frame including the same, which can prevent the folding and positioning structure of the carrying frame from being loosened due to the jumping of the car during travel. More secure.

The body includes a first rod and a second rod that can be pivoted, including a The clamping component, a first elastic piece, a control component and a connecting rod. The abutment component is arranged on the second rod and can move between a first position and a second position relative to the second rod. One end of the first elastic member is provided on one of the first rod member and the second rod member, and the other end is provided on the engaging component, so that the engaging component has a tendency to move toward the first position. The control assembly is rotatably provided on the second rod around an axial direction and can slide in a locked position and a release position relative to the second rod along the axial direction. The control assembly is radially provided with a clamping part. The connecting rod is connected between the engaging component and the control component. Wherein, when the abutting assembly is located at the first position, the abutting assembly is used to be pressed against the first rod, so that the first rod cannot swing relative to the second rod; when the abutting assembly moves to When the second position is in the second position, the abutting component does not engage the first rod, so that the first rod can swing relative to the second rod. Wherein, when the control assembly is located in the locked position, the clamping portion is used to engage the second rod, and the control assembly cannot rotate relative to the second rod; when the control assembly moves to the release position, the If the clamping part is not clamped against the second rod, the control assembly can rotate relative to the second rod to drive the connecting rod by rotating the control assembly, so that the connecting rod drives the blocking assembly to move to the first rod. Two positions.

In order to achieve the above object, the present invention further provides a carrier frame, including a folding positioning structure of the carrier frame as described above, the carrier frame further includes a body, the body includes a first rod member and a pivoted A second rod member, one of the first rod member and the second rod member is provided with a support bracket for supporting the bicycle, and the other is used for assembling a mounting rod of an automobile.
