Abstract

The utility model discloses a saddle turnover structure for a bicycle, which comprises a saddle, a saddle pipe, a saddle beam, a supporting plate, a middle plate, a pressure plate, a pin shaft and a pin hook, wherein the supporting plate is fixed on the top end of the saddle pipe, and is riveted with the middle plate through the hinge of the pin shaft. The saddle beam is arranged and clamped between the pressure plate and the middle plate, and is fixed by a screw bolt. The pin hook is riveted with the middle plate through the hinge of the pin shaft, and the lock tongue of the pin hook can be hooked on the bottom part of the supporting plate tightly, which fixes and locks the saddle tightly. The utility model can be turned upwards by 90 DEG, and can meet the special requirements of folding bicycles. The utility model has the advantages of reasonable design, high safety, low cost, convenient fold, small size and beautiful appearance.

Description

The bicycle saddle switching mechanism

The utility model relates to the manufacturing of bicycle saddle.

Traditional bicycle saddle comprises saddle body, the seatpillar that saddle face and saddle beam constitute, the saddle body is fixed on the seatpillar by clamping structure, this kind saddle can not overturn, this saddle uses on folding bicycle, inconvenience is used to fold, influence folding function, and influence the overall appearance of folding bicycle.

The purpose of this utility model is to provide a kind of bicycle saddle switching mechanism, and it can upwards overturn 90 °, can satisfy the specific (special) requirements of folding bicycle.

The utility model comprises saddle body, seatpillar, and the saddle beam is fixed on the seatpillar by clamping structure, and it comprises that also supporting plate, middle plate, pressing plate, bearing pin and latch hook constitute, and supporting plate is fixed on the top of seatpillar, and rivets with pin hinge with middle plate; Saddle beam on the saddle body places between pressing plate and the plate and clamps, and uses bolt; Latch hook is to be made of latch hook arm, stingy handle and pin tongue; Latch hook and middle plate are riveted by pin hinge, and the dead bolt on the latch hook can hook the bottom of supporting plate, and the saddle body is locked.

This reality is novel to be described in detail as follows with reference to accompanying drawing:

Fig. 1 is the whole generalized section of saddle switching mechanism; Fig. 2 is a saddle rollover states scheme drawing; Fig. 3 is seatpillar and supporting plate connection diagram; Fig. 4 is that the saddle switching mechanism launches scheme drawing.

As shown in the figure, saddle gear includes seatpillar 1, supporting plate 2, middle plate 3, pressing plate 4, latch hook 5, bearing pin 6, torsion spring 7, bearing pin 8, socket bolt 9, saddle beam 10 and saddle 11 composition (see figure 1)s; Seatpillar 1 is by the integrally welded (see figure 3) of required angle with supporting plate 2, and rivets (see figure 1) with middle plate 3 usefulness bearing pins 8 hinges; Fixing of saddle 11 and switching mechanism is that socket bolt 9 is with saddle beam 10 clamp fitting (see figure 4)s with pressing plate 4 and middle plate 3; Latch hook 5 and middle plate 3, and torsion spring 7 are with bearing pin 6 hinges riveted joint (see figure 4).

The utility model is upwards scratched the stingy handle of latch hook 5 with finger when operation, latch hook 5 lower part hook tongues are broken away from the bottom of supporting plate 3, make saddle 11 upwards to overturn 90 ° along the axle center of bearing pin 8, otherwise as long as saddle 11 is pushed downwards, latch hook 5 hooks the bottom complete operation action of supporting plate 3 from guild, because the hook hypogloeeis of latch hook 5 was 45 ° of inclined-plane (see figure 1)s when saddle 11 was pushed downwards, this inclined-plane just in time contacts with the edge of supporting plate 2, latch hook 5 can produce component, with latch hook 5 to extrapolation, after the top of the bottom of plate 3 and supporting plate 2 all contacts in saddle 11 is pressed into, supporting plate 2 is hooked in the bottom that the hook tongue portion of latch hook 5 relies on torsion spring torsion to enter supporting plate 2, thereby reaches the purpose that fixedly secures saddle.

The utility model is reasonable in design, and is safe and reliable, cheap, is particularly suitable for the specific (special) requirements of folding bicycle, is convenient to fold, and it is little to take volume, handsome in appearance.

Claims

1. bicycle saddle switching mechanism, it comprises saddle body, the seatpillar that saddle face and saddle beam constitute, the saddle body is fixed on the seatpillar by clamping structure, it is characterized in that it comprises that also supporting plate, middle plate, pressing plate, bearing pin and latch hook constitute, supporting plate is fixed on the top of seatpillar, and rivets with pin hinge with middle plate; Saddle beam on the saddle body places between pressing plate and the plate and clamps, and uses bolt; Latch hook and middle plate are riveted by pin hinge, and the bottom that the dead bolt on the latch hook can hook supporting plate is locked the saddle body.

2. according to the described bicycle saddle switching mechanism of claim 1, it is characterized in that on latch hook and the middle plate bonded assembly bearing pin torsion spring being installed, can tighten latch hook, firmly the fixed saddle body.
