Description

Technical Field

[0001] The present invention relates to a bracket, in particular to a bracket with adjustable distance. Background Art

[0002] As more and more people begin to pay attention to low-carbon and environmental protection, cycling has become a hot topic again, as it is used for exercise and riding. Many people now carry bicycles when traveling or on road trips. Since bicycles are relatively large, it can be inconvenient to carry them on public transportation. Therefore, a variety of bicycle packaging options have emerged on the market, such as bicycle boxes and bicycle bags.

[0003] Currently, the packaging for bicycles on the market is generally for foldable bicycles, which are easy to carry and significantly smaller in size after folding. When the folded and disassembled bicycles are placed in a bicycle box or bag, the front and rear forks of the bicycles generally need to be protected. Without protection, the front and rear forks are easily deformed due to squeezing during transportation. Therefore, for different bicycles, since the distances between the front and rear forks are different, they need to be protected with separate accessories to ensure that there will be no problems when the bicycles are subsequently installed. Summary of the Invention

[0004] Based on the above problems, the present invention proposes an adjustable bracket, which can adjust the distance of the bracket according to the distance between the front fork and rear fork of different folding bicycles, and then fix the bracket to the front fork and rear fork respectively, so that even if the bicycle is squeezed during transportation, its front fork and rear fork will not be deformed.

[0005] The technical solutions adopted in the present invention are as follows:

[0006] An adjustable bracket comprises an adjusting tube and an adjusting column. The adjusting tube and the adjusting column cooperate to adjust the length of the bracket.

[0008] A protrusion is provided on one side of the inner wall of the first adjustment hole; the protrusion divides the adjustment hole into a transition area and a bayonet area;

[0009] The adjusting column is cylindrical and hollow, with an open front end and a closed bottom end; a grip ring is provided at the bottom; a plurality of grooves are evenly arranged on the grip ring; two symmetrical second fixing blocks are also provided on the grip ring; a plurality of cylindrical clamping columns are provided on the surface of the adjusting column; the clamping columns are located on the surface of the adjusting column; the clamping columns correspond to the slide grooves;

[0010] The clamping column slides into the slide groove, rotates, enters the transition area of ​​the adjustment hole, and then rotates again to overcome the protrusion and enter the bayonet area. That is, the entry of the clamping column into the bayonet area is equivalent to installing the adjustment column in the adjustment cylinder; the required length is achieved by the distance the clamping column enters into the adjustment cylinder.

[0011] Furthermore, a second adjustment position is provided on the other side of the slide groove, and the structure of the second adjustment position is the same as that of the first adjustment position.

[0012] Furthermore, the position of the second adjustment hole on the second adjustment position and the position of the first adjustment hole on the first adjustment position are offset from each other.

[0013] Furthermore, the first fixing block and the second fixing block have the same shape, which is trapezoidal.

[0014] Furthermore, the first adjustment hole and the second adjustment hole have the same structure and are in an "n" shape.

[0015] Furthermore, a reinforcing rod is provided in the adjusting column. The reinforcing rod is rectangular and runs through the entire adjusting column.

[0016] Furthermore, there are 9 clamping posts in total, the first intervals between the first five clamping posts are the same; the second intervals between the sixth to ninth clamping posts are the same; and the length of the second interval is greater than the length of the first interval.

[0017] Furthermore, the inner walls of the two first adjustment holes at the front end opening of the adjustment cylinder are provided with protrusions.

[0018] Furthermore, an adjustable bracket also includes a mounting strip, which is made of elastic material. The mounting strip includes a protective part and a distance adjustment part, which are integrated into one body; the protective part is heart-shaped, with a protective pad in the middle; one end of the protective pad is fixed to the protective part; circular holes are opened at both ends of the protective pad; the distance adjustment part is strip-shaped, with several grooves evenly opened on it, and a circular hole is opened in each groove.

[0019] The present invention can adjust the distance between the brackets according to the distance between the front fork and the rear fork of different bicycles, and realizes the length adjustment of the brackets by matching the clamping column on the adjustment column with the first adjustment hole or the second adjustment hole.

[0020] Match a mounting strip with the adjusting cylinder: place the protective pad in the protective part of the mounting strip on the bottom end of the adjusting cylinder, insert the round hole into the first fixing column formed by the adjusting cylinder and the first fixing block, and insert the round hole at the other end located in the protective part into the second fixing column formed by the adjusting cylinder and the other first fixing block. The mounting strip is fixed on the adjusting cylinder. The length of the first fixing column is greater than that of the second fixing column, and the first fixing column can be inserted into the thickness of the two round holes.

[0021] Similarly, match another mounting strip with the adjusting column: place the protective pad in the protective part of the mounting strip on the bottom end of the adjusting column, insert the round hole into the fourth fixing column formed by the adjusting column and the second fixing block, and insert the round hole at the other end located in the protective part into the third fixing column formed by the adjusting column and the other second fixing block. The mounting strip is fixed on the adjusting column. The length of the fourth fixing column is greater than that of the third fixing column, and the fourth fixing column can be inserted into the thickness of the two round holes.

[0022] Then, according to the actual distance required, fix the adjusting column in the adjusting cylinder: the column slides into the slide groove, rotates, enters the transition area of ​​the adjusting hole, and then rotates again to overcome the protrusion and enter the bayonet area. If the adjusting cylinder is provided with a pair of adjustment positions, the adjusting column can only rotate clockwise or counterclockwise (depending on which side of the slide groove the adjustment position is on); if the adjusting cylinder is provided with two pairs of adjustment positions, located on both sides of the slide groove, the adjusting column can rotate clockwise or counterclockwise to control the distance more accurately.

[0023] Then, an installed distance adjustment part is passed around a front fork, and the circular hole on the distance adjustment part is inserted into the first fixed column. The distance adjustment part has several circular holes that are fixed at different positions according to actual conditions. It is only necessary to fix the front fork and the adjusting cylinder without moving them. The distance adjustment part on the adjusting column passes around another front fork, and the circular hole on the distance adjustment part is inserted into the fourth fixed column. The distance adjustment part has several circular holes that are fixed at different positions according to actual conditions. It is only necessary to fix the front fork and the adjusting column without moving them, and the present invention can be installed on the front fork.

[0024] The present invention can adjust the length of the bracket according to the actual distance by adjusting the position of the clamping column in the adjustment hole; furthermore, the bottom ends of the adjusting tube and the adjusting column are closed and respectively contact the front fork, and protective pads are respectively installed at the bottom ends to prevent the bottom ends from directly contacting the front fork to avoid damaging the front fork.
