The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Shown in Fig. 3,4, a kind of bicycle profile tube structure of improvement mainly is made up of a straight tube 10, a transverse tube 20, an axostylus axostyle 30 and a push-tight device 40.
Described straight tube 10 tops are provided with a projection 101, and the horizontal tooth bar 102 of multiple tracks is established on this projection surface, and the center is provided with a horizontal axis hole 103, and are provided with a long slot 104 forwardly and are communicated with horizontal axis hole 103.
Described transverse tube 20 two ends are respectively equipped with the U-joint 204 of a branch of young 201 and one auricle by two flat shapes (202,203) and tooth bar district 200 formations, one invaginated type, this auricle (202,203) respectively is provided with a perforation (205,206), when joint 204 made up with projection 101 installings, perforation was alignd with axis hole 103.
Described axostylus axostyle 30 passes perforation (205,206) and axis hole 103, cooperates a rivet 301 rivet clasps in axostylus axostyle 30, can make the pivot of transverse tube about in the of 20.
Comprise a push rod 401 and a screw rod 402 in the described push-tight device 40, push rod one end is provided with a collar 403 can entangle axostylus axostyle 30 (when these perforation (205,206) and axis hole 103 are passed in axostylus axostyle 30 cooperations via long slot 104, cooperate and be inserted in), the other end is provided with inner bolt hole 404; Screw rod 402 is screwed in the inner bolt hole 404 of push rod 401 after passing the set lockhole 207 of bundle young 201 earlier again.
When transverse tube 20 is adjusted to required angle, after driver 50 also is adjusted to desired location simultaneously, utilize screw rod 402 1 ends affixed adjustment thick stick 405 screw, make push rod 401 by ejection and make lockhole 207 by packing, this bundle young 201 is just locked driver 50, and transverse tube 20 is moved towards projection 101, and making that the tooth bar 102 of projection 101 is tightly chimeric with the tooth bar district 200 of joint 204, transverse tube 20 securely is combined into one with straight tube 10.In case will adjust angle again, as long as slightly get loose screw rod 402, just make transverse tube 20 mobile slightly to the right, and tooth bar 102 and tooth bar district 200 are broken away from each other, can pivot transverse tube 20 or adjustment driver 50 positions, tie down screw 402 utmost points can again.
In sum,, do not cause transverse tube 20 to break away from straight tube, and drop, hold transverse tube 20 because the utility model is provided with an axostylus axostyle 30 in ground as the transverse tube in the figure one prior art standpipe even screw rod 402 gets loose; The utility model can be adjusted transverse tube 20 angles and driver 50 positions simultaneously in addition, and the standpipe of prior art can't reach this effect.
