Description

Handle mechanism

Technical field

The utility model relates to a kind of handle mechanism, particularly relates to a kind of handle operation mechanism for two-wheeled or three-wheel vehicle.

Background technology

In prior art, for the handle mechanism of two-wheeled or three wheel brakes, comprise handle and handle pipe, fix a connection piece in handle pipe, handle is hinged by a rotating shaft and attaching parts.The arranged outside handlebar rubber cover of handle pipe, holds the operating portion at gum cover middle part, to operate handle pipe, controls direction.When vehicle need to be braked, the handle of holding with a firm grip.But, because braking transmission link is relatively many, particularly for the mechanism of front and back wheel interlock braking, need larger strength could realize braking completely, this is not easy to personage's operating handle mechanism that strength is less, and has certain potential safety hazard.

Therefore those skilled in the art are devoted to develop the light labour-saving of a kind of operation handle mechanism.

Utility model content

Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the light labour-saving of a kind of operation handle mechanism.

For achieving the above object, the utility model provides a kind of handle mechanism, comprises handle and handle pipe, fixes a connection piece in handle pipe; Described handle is hinged by a rotating shaft and described attaching parts; On described attaching parts, be provided with drag-line; In described handle pipe, be provided with gum cover; The ratio of the distance of the operating portion center of described gum cover and the distance of described spindle central and described drag-line attachment point center and described spindle central is 4.1-5.

Preferably, described attaching parts is oil pump; Described oil pump is fixed in described handle pipe by anchor ear; On described oil pump, one is arranged at intervals with the first flange and the second flange; Described oil pump actuating mechanism and handle are arranged at the gap between described the first flange and the second flange; Described rotating shaft is bolt, is connected successively through described the first flange, oil pump actuating mechanism, handle with after the second flange with jam nut; The end of described handle is bolted the balance block that can stir described oil pump actuating mechanism; Described drag-line is arranged on the bottom of described balance block by drag-line pin.

Preferably, described ratio is 4.3-4.5.

The beneficial effects of the utility model are: the utility model is simple in structure, and rapid operation is easy and convenient.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Embodiment 1: as shown in Figure 1, a kind of handle mechanism, comprises handle 1 and handle pipe 2, fixes a connection piece 3 in handle pipe 2, handle 1 is hinged with attaching parts 3 by a rotating shaft 4.

On attaching parts 3, be provided with drag-line 5, in handle pipe 2, be provided with gum cover 6.The distance L 2 at the operating portion 6a center of gum cover 6 and rotating shaft 1 center is 4.3 with the ratio of the distance L 1 at drag-line 5 attachment point centers and rotating shaft 1 center, in other specific embodiment, this ratio also can be other values between 4.1-5, as 4.2,4.4,4.5,4.6,4.7,4.8,4.9 etc., to reach essentially identical technique effect.If ratio is too small, operation effort, if ratio is excessive, is not easy to holding with a firm grip of handle 1.

While needing drag, navigating mate is caught the tight handle 1 of holding of gum cover operating portion 6a.

Embodiment 2: as shown in Figures 2 and 3, the structure of the present embodiment is substantially the same manner as Example 1, difference is, and attaching parts is oil pump 3, and oil pump 3 is fixed in handle pipe 2 by anchor ear 8.On oil pump 3, one is arranged at intervals with the first flange 3a and the second flange 3b, and oil pump actuating mechanism 9 and handle 1 are arranged at the gap between the first flange 3a and the second flange 3b.Rotating shaft 4 is bolt, is connected successively through the first flange 3a, oil pump actuating mechanism 9, handle 1 with after the second flange 3b with jam nut 11.The end of handle 1 is bolted the balance block 10 that can stir oil pump actuating mechanism 9, and drag-line 5 is arranged on the bottom of balance block 10 by drag-line pin 11.

Other structures and the principle of work of the present embodiment are identical with embodiment 1.

More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical personnels are in the art complied with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
