This kind of cooperation to standpipe and cone nut is through deformation and locking with the front fork riser more easily, is favorable to improving operation convenience and joint strength, can also avoid the cone nut to skid the standpipe relatively through the cooperation of locating lever and logical groove, is favorable to improving connection stability between the two. In addition, the pin is used as a protrusion, the requirement of mutual abutting with the end cover can be met, and therefore the screw rod drives the cone nut to withdraw from the tail end of the vertical pipe, locking of the screw rod and the end cover is removed, and adjustment of the vertical pipe is achieved.
Example three, as shown in fig. 6.
An adjustable vertical tube structure is characterized in that a plurality of through grooves 21 communicated from an outer wall to an inner wall are formed in the circumferential direction of one end, located in a front fork vertical tube 1, of a vertical tube 2; the tensioning block 3 is a spherical nut; the rest is the same as the first embodiment.
In the locking device for the vertical tube, the spherical nut applies outward tensioning acting force to the end part of the vertical tube by inserting the spherical surface into the end part of the vertical tube so as to mutually fix the vertical tube and the front fork vertical tube.
Example four, as shown in fig. 7-9.
A riser locking device is characterized in that a limiting mechanism is a quick-release assembly and comprises a concave platform 42 arranged on one side, back to a tensioning block 3, of an end cover 4, a lantern ring 51 arranged at the end part of a pull rod 5 and located at the concave platform, and a wrench 8 with a cam arranged at one end, wherein the wrench and the lantern ring are hinged to the concave platform through an eccentric rotating shaft part 7; the rest is the same as the first embodiment.
The quick-release assembly usually fixes two mutually sleeved pipe fittings through a pipe clamp, the embodiment utilizes the principle of the quick-release assembly, and the wrench is abutted against an end cover through a cam at the end part of the wrench in the rotating process to exert an interaction force and exerts an action on the pull rod through the eccentric rotating shaft piece and the lantern ring; when the cam on the spanner rotates to the maximum diameter position, the pull rod also moves to the outermost end position, and the tensioning block connected to the pull rod is also tightly propped against the vertical pipe to the maximum extent, so that the vertical pipe is clamped on the front fork vertical pipe. Through the use of this kind of quick detach subassembly, can greatly improve convenient operation nature.
