CN2352427Y - Insertion type seat pillar of bicycle saddle - Google Patents

Abstract

The utility model discloses an insertion type seat pillar of a bicycle saddle, comprising a wedge sheath provided with a wedge hole and a wedge shaft whose one end is provided with a bevel wedge, and the wedge sheath and the wedge shaft are mutually matched together into a group, wherein, the wedge shaft and the wedge sheath are respectively arranged in the holes of the bicycle frame and the saddle with the original clamping and fastening method, so the saddle and the bicycle frame are positioned stably under the action of the gravity of the human body. When the bicycle is stored, the saddle can be separate from the bicycle frame at any time, so the used bicycle without a saddle is suspected so as to enhance the theft protection function of the utility model which can also be used in the bicycle frame holes of the tricycle or other manpower vehicles.

Description

The plug-in type saddle pipe that connects bicycle saddle

The utility model relates to attachments of a bicycle, specifically a kind of plug-in type saddle pipe.

Bicycle is stolen, a present no small problem that has become harm social security, although the once normal organizational strength of public security department, the enforcement of seeking unity of action is hit, and the dwelling district reinforcement also is difficult to fundamentally address this problem to the unified management of bicycle.Bicycle theft-prevention is always set about from lock, but after bicycle lock is pried open, just is beyond recognition and steals the suspect, yet has certain problem to hitting the offender.

The purpose of this utility model is: set about designing a kind of plug-in type saddle pipe that connects bicycle saddle from the saddle of bicycle, can solve the problem that exists in the prior art field.

For achieving the above object, the technical scheme that the utility model adopted is: it comprises that wedge axle that the cover of wedge that has slanting wedge hole and an end have wedge cooperatively interacts and combines.

Below in conjunction with accompanying drawing, provide details of the present utility model by description to embodiment.

Description of drawings:

Fig. 1. structural representation of the present utility model;

Fig. 2. A-A cutaway view of the present utility model;

Fig. 3. wedge axle construction figure;

Fig. 4. the wedge axis side view;

Fig. 5. the cover of wedge constructional drawing;

Fig. 6. the cover of wedge lateral plan.

As Fig. 1. shown in Figure 2, the utility model is to be cooperatively interacted by the wedge axle 4 that a cover of wedge 2 that has slanting wedge hole 1 and an end have a wedge 3 to combine.Wedge is for having the multiedge cylinder on an inclined-plane at least.

As Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in, wedge is oblique tri-prismoid, angle α=10 of its C face and axis °～25 °, angle β=40 of other two sides d, e °～120 °.Tiltedly the angle of the C face of tri-prismoid and axis is preferably α=12 °～15 °, and the angle of other two sides d, e is preferably β=50 °～90 °.

By the saddle pipe that wedge axle and cover of wedge are formed, the b face of its wedge axle 4 (or a face of vehicle frame 2) adopts original clamping fastening method to be installed in the vehicle frame hole, and a face of cover of wedge 2 (or b face of wedge axle 4) adopts original clamping fastening method to be installed in the saddle hole.When riding, under the effect of human body gravity, cover of wedge 2 (or wedge axle 4) under the saddle is closely inserted in the wedge axle 4 (or cover of wedge 2) on the vehicle frame.Under the horizontal force of cammed surface, saddle and vehicle frame form stable location.When depositing,, can make progress to extract easily and take saddle away or car body and saddle are pinned simultaneously with chain lock because wedge is non-self-locking.

Wedge can be made multiple shape, and form thus and singly join, promptly not that the saddle pipe of same hole shape is non-interchangeable, must just can be combined into one group of saddle pipe that is suitable for the wedge axle and the cover of wedge of same hole shape.The saddle pipe of certain same hole shape, also available installation direction difference, though cause saddle can insert vehicle frame, saddle can not be in good position by bike, as the saddle microcephaly backwards or horizontal on one side, so have only saddle with the first wife to connect vehicle frame easily and ride

The utility model compared with prior art, the useful effect that has is: because vehicle frame and saddle are very Easily at any time separable, form asellate bicycle, (being sitting on the luggage carrier) of carrying out or ride During asellate bicycle, cause easily suspicion, strengthen its antitheft function with this. The utility model Also can be contained in the vehicle frame hole of tricycle or other rickshaw and use.
