The antitheft mechanism for the bicycle saddle disclosed by the utility model is simple in structure and is capable of reducing a risk of being stolen of the saddle.
Description
Technical field
The utility model relates to a kind of bicycle saddle burglar-proof mechanism, belongs to technical field of bicycles.
Background technology
At present, bicycle is in order to adjust saddle height according to people's height, in vehicle frame, the upper end of pipe can be provided with bolt assembly, traditional connection mode need to act on the height that can regulate saddle after spanner is unscrewed bolt assembly, cannot meet like this temporary needs adjustment, but also need accessory appliances just can carry out, very inconvenient, also have and adopt in one the quick detach assembly that is spirally connected to replace, the adjusting of saddle height becomes very convenient quick like this, but this quick detach is spirally connected, assembly can also can be unscrewed nut in the situation that there is no accessory appliances, make some lawless persons be easy to just saddle be stolen, cause cyclist to use, can only again buy new saddle, in bringing convenience, also brought the stolen risk of saddle to cyclist.
Summary of the invention
Technical problem to be solved in the utility model is the defect that overcomes prior art, and a kind of bicycle saddle burglar-proof mechanism is provided, and it is simple in structure, can reduce the stolen risk of saddle.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of bicycle saddle burglar-proof mechanism, comprise pipe and the saddle pipe that is connected saddle in vehicle frame, saddle pipe is arranged in vehicle frame in pipe, also comprise anti-theft screw, in described vehicle frame, pipe has the saddle pipe auxiliary section coordinating with saddle pipe and is positioned at the anti-theft pipe portion of below, saddle pipe auxiliary section, and the internal diameter of anti-theft pipe portion is larger than the internal diameter of saddle pipe auxiliary section, in described vehicle frame, in the anti-theft pipe portion of pipe, have when preformed hole is positioned at anti-theft pipe portion with the bottom of convenient saddle pipe and anti-theft screw can be tightened in the bottom outer wall of saddle pipe, the described anti-theft screw being tightened on saddle pipe protrudes outside the inner diameter wall of saddle pipe auxiliary section.
Further, in order to hide preformed hole, in described vehicle frame, pipe is pasted with labeling at the position of preformed hole.
Further, the difference of the internal diameter of described anti-theft pipe portion and the internal diameter of saddle pipe auxiliary section is slightly larger than the nut thickness of anti-theft screw.
Further, for the installation of convenient and theftproof screw, the diameter of described preformed hole is greater than the nut diameter of anti-theft screw.
Further, in described vehicle frame, on pipe, be provided with saddle pipe is clamped in to the clamping part on pipe in vehicle frame.
Adopt after technique scheme, saddle pipe packs Guan Houzai in vehicle frame into anti-theft screw preformed hole on pipe from vehicle frame is screwed into saddle pipe bottom, in vehicle frame, the internal diameter of pipe is designed to up-small and down-big form, the large part of anti-theft pipe portion internal diameter below, the saddle pipe that anti-theft screw has been installed can be freely upper and lower in this part, and the saddle pipe auxiliary section internal diameter of upper end is less, the saddle pipe that has made to install anti-theft screw cannot be extracted in vehicle frame and manage again, so just realize the antitheft function of saddle, reduce the stolen risk of saddle, and simple in structure.
Brief description of the drawings
Fig. 1 is the structural representation of bicycle saddle burglar-proof mechanism of the present utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Fig. 3 is the exploded perspective view of the bicycle saddle burglar-proof mechanism of Fig. 1.
Detailed description of the invention
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below,
As shown in Fig. 1 ~ 3, a kind of bicycle saddle burglar-proof mechanism, comprise in vehicle frame, manage 1 with the saddle pipe 3 that is connected saddle 2, saddle pipe 3 is arranged in vehicle frame and manages in 1, also comprise anti-theft screw 4, in vehicle frame, managing 1 has the saddle pipe auxiliary section 1-2 coordinating with saddle pipe 3 and is positioned at the 1-3 of anti-theft pipe portion of saddle pipe auxiliary section 1-2 below, and the internal diameter of the 1-3 of anti-theft pipe portion is larger than the internal diameter of saddle pipe auxiliary section 1-2, in vehicle frame, manage on 1 the 1-3 of anti-theft pipe portion and have when preformed hole 1-1 is positioned at the 1-3 of anti-theft pipe portion with the bottom of convenient saddle pipe 3 and anti-theft screw 4 can be tightened in the bottom outer wall of saddle pipe 3, the anti-theft screw 4 being tightened on saddle pipe 3 protrudes outside the inner diameter wall 3-1-1 of saddle pipe auxiliary section 1-2.
In order to hide preformed hole 1-1, as shown in Figure 2, in vehicle frame, manage 1 and be pasted with labeling 5 at the position of preformed hole 1-1.Cover preformed hole 1-1 completely.
As shown in Figure 1, the difference of the internal diameter of the internal diameter of the 1-3 of anti-theft pipe portion and saddle pipe auxiliary section 1-2 is slightly larger than the nut thickness of anti-theft screw 4.Now saddle pipe 3 can easy on and off adjustment, but is greater than and in saddle pipe 3 and vehicle frame, manages the interval gap of 1 upper end and cannot take out because be screwed in the nut thickness of the anti-theft screw 4 on saddle pipe 3.
As shown in Figure 1, the diameter of preformed hole 1-1 is greater than the nut diameter of anti-theft screw 4.
As shown in Figure 1, in vehicle frame, manage to be provided with on 1 saddle pipe 3 is clamped in and in vehicle frame, manages the clamping part 6 on 1.
Principle of work of the present utility model is as follows:
