Description

The first pipe of bicycle handle shock absorption device

The utility model relates to a kind of bicycle, particularly about a kind of improvement of bicycle handle.

The first pipe of the bicycle handle commonly used is at its top one connecting support to be set, and connects the handle cross bar by connecting support, connects handle by the handle cross bar, is connected a shock absorber simultaneously between cross bar and connecting support, and this shock absorber can make handle have vibration reduction efficiency.This cross bar of commonly using is directly to be articulated in connecting support central authorities, and the vibration arm of force that cross bar extended is shorter, so under identical pivot angle, buffering capacity is less, shock absorber can't effectively be brought into play function, and perhaps it is under identical pendulum distance, and its handle angle of rotation causes the knight to grip unstable phenomenon than Da Yi.

At the problems referred to above, the purpose of this utility model provides the first pipe of the better bicycle handle of a kind of damping effect shock absorption device.

To achieve these goals, the utility model is taked following design: the first pipe of a kind of bicycle handle shock absorption device, it comprises the connecting support that the handle-bar stem top is provided with, the handle cross bar that articulates on the described connecting support, the shock absorber that is embedded between described connecting support and the described cross bar, and bonded assembly handle on the described cross bar, it is characterized in that: on described connecting support, be the center with described handle-bar stem, extend an opposite side who connects described handle direction at described cross bar, one articulated section is set, described handle cross bar is articulated in described articulated section.

Described handle cross bar can be to be formed by two lamellar bodies and group, described two lamellar bodies, one end has the circular arc caulking groove, be mated, one intermediate plate that also has a circular arc caulking groove is set, and described intermediate plate and described two lamellar bodies articulate, and have a hole on the described intermediate plate, be mated, one locating piece with lockhole is set, and passes described hole and described lockhole, with the described handle that locks by a bolt.

The nearly stage casing of described two lamellar bodies can be provided with a shrinkage pool, the embedding axle of two lateral processes of described shock absorber upper end is hubbed in the described shrinkage pool, in the hook portion of the lower end of described shock absorber interlocking on described connecting support.

The side place in addition of articulated section can be provided with an arcuate socket relatively on described connecting support, wears guide rod in described two lamellar bodies, and described guide rod runs through the described arcuate socket of described connecting support in the lump, and is embedded a bump rubber on described arcuate socket top.

The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to be the center with the handle-bar stem on connecting support, extend an opposite side who connects handle direction with respect to cross bar, establish an articulated section, the handle cross bar is articulated on the articulated section, thereby the length of the vibration arm of force that extended, make handle under identical pivot angle, can increase buffering capacity, perhaps under identical pendulum distance, can reduce the handle anglec of rotation, therefore can improve buffering usefulness, reach the purpose of damping.2, the utility model is owing to be provided with two lamellar bodies, and cooperates intermediate plate, locating piece to form folder lock handle hand structure with two lamellar bodies, therefore is easy to make, and it is convenient that lock is established handle.3, the utility model is owing to establish arcuate socket on connecting support, and is embedded bump rubber on the arcuate socket top, and guide rod is passed through arcuate socket, can limit the angular oscillatory motion in arcuate socket, and can be cushioned by bump rubber, therefore can improve rotation stability, avoids member to damage simultaneously.The utlity model has good damping effect, be easy to make, conveniently lock and establish handle and rotation stable characteristics, it can be widely used in the various bicycles.

Below in conjunction with accompanying drawing the utility model is described in detail.

As shown in Figure 1, the utility model basic structure is as commonly using structure, and it is to establish a connecting support 11 on handle-bar stem 10 tops, on connecting support 11, articulate leader's cross bar 20, between connecting support 11 and cross bar 20, be connected a shock absorber 30, connect handles, thereby reduce vibrations by cross bar 20.Principal character of the present utility model is: be the center with handle-bar stem 10 on connecting support 11, extend an opposite side who connects handle direction at cross bar 20, one articulated section 12 is set, handle cross bar 20 is articulated on the articulated section 12, length with the lengthening vibration arm of force makes it under identical pivot angle, can increase buffering capacity, perhaps under identical pendulum distance, can reduce the handle anglec of rotation, and then improve buffering usefulness.Wherein, handle cross bar 20 can be to be formed by two lamellar bodies 200 and group, and two lamellar bodies, 200 1 ends have circular arc caulking groove 21, and is matched with the be pivoted intermediate plate 22 of a tool circular arc caulking groove 220 of this end.Intermediate plate 22 is provided with a hole 221, and establishes a positioning block 23 at this end, and locating piece 23 is provided with a lockhole 230 that matches with the hole 221 of intermediate plate 22, and bolt 24 passes hole 211 and lockhole 230 locking handles.Be provided with the embedding axle 31 of shrinkage pool 25, two shrinkage pools 25 in two lamellar bodies, 200 nearly middle sections, in the hook portion 13 that the lower end interlocking of shock absorber 30 is provided with on connecting support 11 for interlocking shock absorber 30 upper ends two lateral processes.Relative articulated section 12 is provided with an arcuate socket 14 on connecting support 11, and a guide rod 15 is cooperated two lamellar bodies 200, runs through the arcuate socket 14 of connecting support 11, guide rod 15 is moved in a circle along arcuate socket 14, and be embedded a bump rubber 16 on arcuate socket 14 tops.

As shown in Figure 1 and Figure 2, the utility model when combination,, locating piece 23 two ends are plugged on two lamellar bodies, 200 1 ends respectively earlier with two lamellar bodies 200 and put, by a pivot and screw two lamellar bodies 200 are articulated on the intermediate plate 22 again, make intermediate plate 22 be the state that an end can be raised.The embedding axle 31 of both sides, shock absorber 30 upper end is embedded in the shrinkage pool 25 of two lamellar bodies 200, makes to form the pivot joint state between shock absorber 30 upper ends and two lamellar bodies 200.The end of two lamellar bodies 200 is articulated on the articulated section 12 of first pipe 10 connecting supports 11, and the lower end of shock absorber 30 is embedded in the hook portion 13 of connecting support 11, form pivotable state.Arcuate socket 14 tops at connecting support 11 are embedded bump rubber 16 in advance, wear guide rod 15 again in two lamellar bodies 200, make guide rod 15 run through the arcuate socket 14 of connecting support 11.

In the foregoing description, as shown in Figure 4, handle-bar stem 10 and connecting support 11A also can be designed to the form of split.

As Fig. 3, shown in Figure 5, when the utility model uses, head is managed 10 to be installed on the bicycle, intermediate plate 22 is opened, handle 40 is embedded in the caulking groove 21 of two lamellar bodies 200, again intermediate plate 22 is covered, make the caulking groove 220 of intermediate plate 22 cooperate the caulking groove 21 of two lamellar bodies 200 and intactly encase handle 40, locking bolt 24 in intermediate plate 22 and locating piece 23 can make handle 40 be fixed on effectively on the lamellar body 200.When handle 40 bears when pressing down strength, pressure can be oppressed shock absorber 30, because the pooling feature of shock absorber 30, thereby can reach the effect of handle damping.When shock absorber 30 restores to the original state, when guide rod 15 moves on arcuate socket 14, can contact bump rubber 16, by the buffer action of bump rubber 16, can avoid metal to collide mutually and the knight's sense of discomfort and the member that cause damage.
