Abstract

The utility model relates to a shock-absorbing pillar for a bicycle saddle, comprising a lower pipe part which can be plugged into the frame tube of the triangle frame and an upper tube part used for mounting saddles. The utility model is characterized in that a shock-absorbing device is arranged between the upper tube and the lower tube, and the shock-absorbing device is jointed and welded by two blocks of hexa claw shape dish-shaped spring pieces. The utility model can automatically tune the pressure borne on different positions of the saddle, the range of the springs is great, and riders with different weights can feel shock-absorbing effect under the condition of poor roadbed, making riders feel smooth and comfortable. The utility model which has the advantages of simple and delicate structure, easy fabrication and low cost is generally used for bicycles with various types.

Description

Shock-absorbing pillar for bicycle saddle

The utility model relates to and be used for the saddle pillar that bicycle saddle is installed, especially a kind of bicycle seat post with damping effect.

The ordinary bicycle saddle pillar is a rigid pipe, its effect is only for being convenient to the connection between saddle and the bicycle triangular frame, bicycle is advanced in the process, owing to the uneven vibrations that produce of road only depend on the spring on the saddle to absorb, thus minimizing cyclist's the sense of jolting; Its damping effect is limited.When riding fast, it is not ideal enough that its damping effect just shows.Chinese patent discloses the patent of multinomial relevant bicycle elastic force saddle pillar aspect for this reason, as: CN2047654U " elasticity seatpillar ", CN2031780U " bicycle saddle cushion shock absorber " etc.These elastic force saddle pillars all adopt compositions such as fall way, portable bar, inside and outside compression spring and locations, and it has played buffering, cushioning effect, has improved the damping effect of saddle, makes the cyclist feel comfortable.But its structure is complicated, and cost cost height is installed also inconvenient.

The purpose of this utility model is the deficiency that exists at above-mentioned bicycle seat post, and a kind of simple in structure and bicycle saddle shock strut that flexibility is big is provided.

The utility model bicycle saddle shock strut comprises the following tube portion that can insert triangular frame frame pipe and is used to install the last tube portion of saddle, it is characterized in that: also comprise a shock absorption device that is made of two involutory welding of hexa-claw shape patellate spring plate, the both ends of the surface of shock absorption device are the following tube portion and the last tube portion of affixed pillar respectively.

Six pawls of described shock absorption device hexa-claw shape patellate spring plate make that radix unguis is wide, the sharp narrow extension curvilinear structures of pawl.

The damping effect of the utility model bicycle saddle shock strut is determined by its architectural feature: when human body weight acts on the saddle, the pawl point of the hexa-claw shape patellate spring plate of pillar is compressive deformation at first, after the two hexa-claw shape patellate spring plate pawl tips that involute are by a pressing part, this moment, the elastic force of shock absorption device equated with the elastic force of the original perpendicular spring of saddle, the human body weight that acts on the saddle is born jointly by perpendicular spring of saddle and shock absorption device, pressurized elastic force equates, thereby has increased elasticity amplitude and flexibility.The hexa-claw shape patellate spring plate can bear the pressure that acts on diverse location on the saddle by automatic tuning, and the cyclist of different weight all can experience damping effect under the relatively poor situation of roadbed, make the people feel more steadily comfortable.

Bicycle saddle shock strut simple and ingenious structure of the present utility model, easily manufactured, with low cost, damping effect is obvious, is common to the bicycle of various models.

Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.

Fig. 1 is the front view of bicycle saddle shock strut;

Fig. 2 is the birds-eye view of bicycle saddle shock strut shown in Figure 1.

Embodiment: can be clear that from Fig. 1 and Fig. 2 the bicycle saddle shock strut is by the following tube portion 5 that can insert triangular frame frame pipe, the shock absorption device 6 that is used to that the last tube portion 3 of saddle is installed and is arranged between them is formed, shock absorption device 6 is by two hexa-claw shape patellate spring plates, 1,2 involutory being welded, the extension curvilinear structures that six pawls of hexa-claw shape patellate spring plate 1,2 make that radix unguis is 7 wide, pawl sharp 8 is narrow, the both ends of the surface of shock absorption device 6 are the following tube portion 5 and the last tube portion 3 of affixed pillar respectively, and its affixed mode can adopt butt welding or fastener connection structure.Following tube portion 5 can be 10 degree with respect to vertical line and tilt.For the spring leaf 1,2 that prevents shock absorption device 6 is exposed to outer easily hook clothes or scratches skin and flesh, the shock absorption device 6 outer gentle matter sheaths 4 that are provided with.
