Embodiment Construction
[0030] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0031] see Figure 1 to Figure 5 As shown, the present invention discloses a reverse bicycle beam tube installation structure, including a stem structure, a front fork leg structure, a head tube 50, a threaded beam cap ring 60 and a high-strength long screw rod 70 .
[0032] The stem structure includes the riser 10 and the upper inner sleeve 20 arranged below the riser. The upper inner sleeve 20 is a hollow structure that conducts up and down. The riser 10 and the upper inner sleeve 20 are two different Metal body; the bottom of the standpipe 10 is provided with a mounting groove 11, and one end of the upper inner casing 20 is fixedly installed in the mounting groove 11 through structural glue 90.
[0033] The front fork leg structure includes ...

The invention provides a reverse bicycle beam tube mounting structure. The structure includes a bontrager structural component, a front fork leg structural component, a head tube, a threaded bundle cap ring and a high-strength long screw rod; the bontrager structure includes a bontrager tube and an upper inner sleeve arranged below the bontrager tube; the front fork leg structural component includes a front fork leg and a lower beam tube arranged above the front fork leg, the front fork leg is provided with a step hole for installing the lower beam tube and a screw hole which is arranged belowthe step hole and is communicated with the step hole; upper and lower bearing grooves are respectively arranged at the upper and lower ends of the head tube and a pair of upper bearing groove and lower bearing groove are respectively embedded in the upper bearing groove and the lower bearing groove; one end of the high-strength long screw rod penetrates through the screw hole of the front fork leg and penetrates from one end of the lower beam tube to the other end of the lower beam tube. One end of the high-strength long screw rod penetrating out of the lower beam tube is provided with an inclined wedge. According to the invention, the problem that the product can be loosen because of rusty of the bontrager bolt or personal behavior can be avoided during the outdoor service life of the product.
Description
technical field [0001] The invention relates to the fields of public bicycles and shared bicycles, in particular to a reverse bicycle bundle pipe installation structure of a bicycle front fork bundle pipe and a handlebar riser. Background technique [0002] Public bicycles and shared bicycles have relatively high requirements for the safety of outdoor parts of the product, because the product has been placed in an outdoor public environment for a long time, and there are higher requirements for the protection and anti-theft of the parts. [0003] Both public bicycles and shared bicycles are outdoor bicycles, and the front forks are mostly fitted, that is, the seat tube is inserted or inserted into the front fork bundle tube from above to realize the axial and radial locking and fixing of the front fork and the seat tube. [0004] The disadvantage of this installation method is that the head of the locking bolt is on the upper part of the standpipe and is exposed to the outsi...
