Description
Technical field
The utility model relates to bicycle structure, refers in particular to the locking mechanism of bicycle handle standpipe and front fork.
Background technology
As shown in Figure 1, stem and front fork locking constructional drawing for existing bicycle, wherein the midway location of the front fork 10 of bicycle is provided with the core bar 11 of a hollow and is provided with the axostylus axostyle 21 and the green phase that can correspondingly be inserted in core bar 11 at the midway location of stem 20 and closes the locking assembly with core bar 11 and axostylus axostyle 21 lockings, thereby stem 20 is connected with front fork tube 10.
The structure of latch assembly generally as shown in Figure 1, in the middle of the front fork 10 and axostylus axostyle 21 belows are provided with a spiro connecting piece 13, other has a bolt 31 to be spirally connected with spiro connecting piece 13, and its spiro connecting piece 13 and the subsides bottom surface of axostylus axostyle 21 are the diagonal plane form of corresponding combination, so can core bar 11 and axostylus axostyle 21 be locked, thereby stem 20 is connected with front fork 10 by bolt 31.But the locking mechanism of this stem and front fork can't be regulated the stem height neatly, can not satisfy the crowd's of different heights user demand effectively.
The utility model content
Technical problem to be solved in the utility model is: the locking mechanism of a kind of bicycle handle standpipe and front fork is provided, and it is simple in structure, is connected firmly, and can regulates the stem height easily.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the locking mechanism of a kind of bicycle handle standpipe and front fork comprises stem, front fork and latch assembly.The bottom of stem is provided with intubate; The front fork top is provided with the container cavity of upward opening; Described latch assembly comprises bundle son and fastener, the last trepanning that the young center of described bundle is provided with mutual perforation reaches trepanning down, the side of last trepanning, following trepanning is extended with a pair of folder ear respectively, and also is provided with the gap that communicates with corresponding upward trepanning, following trepanning between the two folder ears of every pair of folder ear; Described front fork top is inserted in down in the trepanning, and the intubate of stem is inserted and inserted from last trepanning and extends in the container cavity of front fork, and upward every pair of folder ear of trepanning, following trepanning side is also locked by fastener respectively.
The beneficial effects of the utility model are: by cooperating with fastener, can easily stem, front fork be locked respectively securely by means of bundle is young, and simple in structure; And can regulate the degree of depth that intubate is inserted by the fastener that unclamps on the trepanning side, thus regulate the stem height, to make things convenient for the rider.

The specific embodiment
As Fig. 2, Fig. 3 and shown in Figure 4, the utility model provides the locking mechanism of a kind of bicycle handle standpipe and front fork, comprising: stem 40, front fork 50 and latch assembly.
Wherein, described stem 40 bottom dead center position directly are provided with an intubate 401.
Described latch assembly comprises a branch of young 60, and the midway location of described bundle young 60 is provided with on one trepanning 601 and trepanning 602 once, and go up trepanning 601, time trepanning 602 communicates.Last trepanning 601, following trepanning 602 insert for the intubate 401 and the front fork 50 of stem 40 respectively, the last trepanning 601 of bundle young 60, following trepanning 602 junctions laterally are provided with a groove 603 does not disturb trepanning 601, following trepanning 602 mutually, and be extended with a pair of folder ear 604,605 respectively at side, have one between two folder ears of every pair of folder ear 604,605 and go up the gap 606,607 that trepanning 601, following trepanning 602 communicate with corresponding.And be provided with fastener in addition with the locking of two of ear 604,605 folders of every pair of folder ears, be placed in its in-to-in parts thereby make the aperture of trepanning 601, time trepanning 602 dwindle to clamp.Described fastener can be tie down screw 608,609; Certainly, described tie down screw also can adopt the quick detach fastener to substitute, and as shown in Figure 5, thereby more convenient in the operation, this quick detach fastener is used on such as products such as folding bicycles very extensive, at this its concrete structure is just seldom given unnecessary details.
During assembling, the following trepanning 602 that at first will restraint son 60 is placed on front fork 50 tops, and the top that makes front fork 50 is with the following trepanning 602 of bundle young 60 and the step surface applying of last trepanning 601 junctions.Again the container cavity 501 of front fork 50 is inserted and inserted to the intubate 401 of stem 40 to the degree of depth that adapts to from the last trepanning 601 of restrainting son 60, again tie down screw 608,609 is screwed respectively, last trepanning 601 covers of bundle young 60 are fixed on the intubate 401 of stem 40, and following trepanning 602 covers are fixed in the top of front fork 50.Thereby stem 40 is connected with front fork 50, reach stem 40 and be fixedly arranged on front fork 50 apical end.In the time must adjusting the height of stem 40, the tie down screw 608 of need only loosening just can arbitrarily be adjusted.
