Abstract

The utility model discloses a hydraulic shock-absorber of an iron shoulder, which comprises a vertical tube, the iron shoulder and a shock-absorber; a steering limiter is arranged at a joint between the vertical tube and the iron shoulder; the joint between the vertical tube and the iron shoulder is welded; both ends of the iron shoulder are respectively provided with a connecting hole; the handle tubes of the shock-absorber are inserted into the connecting holes on both ends of the iron shoulder; the joints between the handle tubes and the iron shoulder are welded; and cover caps are respectively arranged on the handle tubes on both ends of the iron shoulder. The hydraulic shock-absorber of the iron shoulder has the beneficial effects that: the price is lower, and the rainwater corrosion resistance and the firmness are stronger.

Description

A kind of iron shoulder liquid damper

Technical field

The utility model belongs to front fork bumper field, more specifically relates to a kind of iron shoulder bumper that is used on the Electrical Bicycle front fork.

Background technology

At present, atmospheric contamination is more and more serious, and wherein the Ren Lei tail gas that walking-replacing tool produced is exactly an important source to the pollution of atmosphere, human tail gas for the generation of emission abatement walking-replacing tool, the mode of using is varied, and Electrical Bicycle is exactly one of its mode.At present, iron shoulder on the Electrical Bicycle front fork is owing to use ironcasting to make, therefore fracture easily, some iron shoulder is that the handle pipe on the bumper is inserted in the mounting hole at iron shoulder two ends with the bumper connection mode, opens a finedraw in a side of mounting hole, with screw finedraw is being tightened, to reach the fixedly effect of bumper, if but that screw is twisted is too tight, just destroy mounting hole easily, make it have potential safety hazard; In addition, when raining, the rainwater that drips on the Electrical Bicycle front fork also can cause corrosion to the iron shoulder, and its period of service is shortened.

Above-mentioned hidden danger will be brought serious potential safety hazard to the personnel that drive these vehicle, more seriously traffic accident might occur, not only oneself also be brought great threat to autre vie safety.

The utility model content

In order to solve the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of cost lower, easy fracture but also can not recruit the iron shoulder bumper of rainwater corrosion not.

To achieve these goals, the utility model is by the following technical solutions:

A kind of iron shoulder bumper, comprise standpipe, iron shoulder, bumper, the junction of described standpipe and iron shoulder is provided with a limiting steering device, the junction of described standpipe and iron shoulder is welded, described iron shoulder two ends are respectively equipped with a connecting bore, the handle pipe of described bumper inserts the connecting bore at iron shoulder two ends, and the junction of described handle Guan Yutie shoulder is welding, inserts the handle pipe at iron shoulder two ends one block is installed respectively.

Preferably, described bumper is liquid damper or spring damper.

Preferably, described iron shoulder is made for the steel board blanked part.

Preferably, described iron shoulder surface spraying one deck corrosion-resistant coating.

Preferably, described block is that plastics are made.

Of the present utility modelly helpful be: cover at the block on the handle pipe and be sprayed on the corrosion that corrosion-resistant coating on the iron shoulder can actv. prevents rainwater, make it form integral type after iron shoulder and the bumper welding, the enhancing fastness; The iron shoulder adopts the steel board blanked part to make, and fastness is stronger.The cost of this equipment is lower in addition.

Description of drawings

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

Fig. 2 is the structural representation of the utility model iron shoulder.

Among the figure 1, standpipe; 2, rotary stopper device; 3, iron shoulder; 4, bumper; 5 handle pipes; 6 blocks; 31, the connecting bore in the middle of the iron shoulder;

32,33, the connecting bore at iron shoulder two ends.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is made further description explanation.

A kind of as depicted in figs. 1 and 2 iron shoulder liquid damper, comprise standpipe 1, iron shoulder 3, bumper 4, standpipe 1 is provided with a limiting steering device 2 with the junction of iron shoulder 3, limiting steering device 2 is to prevent the Electrical Bicycle ovdersteering, standpipe 1 passes the connecting bore 31 in the middle of the iron shoulder 3, and the upper outlet and the following outlet of the connecting bore 31 in the middle of iron shoulder 3 all use automatic welding machine and standpipe 1 to weld, its fastness is strengthened, take on 3 two ends at iron and offer a connecting bore respectively, the handle pipe 5 insertion iron of bumper 4 are takeed on the connecting bore 32 at 3 two ends, in 33, the handle pipe 5 and the junction of iron shoulder 3 are welded with automatic welding machine, take on the connecting bore 32 at 3 two ends exposing iron, cover a block 6 on the handle pipe 5 outside 33 respectively, block 6 makes made of plastic, can prevent that rainwater is to exposing the connecting bore 32 of takeing on 3 two ends at iron, the corrosion of the handle pipe 5 outside 33; In addition,, iron shoulder 3 is protected, prevented that rainwater from causing corrosion to it at the surface of iron shoulder 3 spraying one deck corrosion-resistant coating.

Bumper 4 can use liquid damper, also can use spring damper.

Iron shoulder 3 is to adopt A3 steel board blanked part to make.

Above-described only is optimal way of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these also should be considered as within the protection domain of the present utility model.

Claims

1. an iron is takeed on liquid damper, comprise standpipe, iron shoulder, bumper, the junction of described standpipe and iron shoulder is provided with a limiting steering device, it is characterized in that, the junction of described standpipe and iron shoulder is welded, and described iron shoulder two ends are respectively equipped with a connecting bore, and the handle pipe of described bumper inserts the connecting bore at iron shoulder two ends, the junction of described handle Guan Yutie shoulder is welding, inserts the handle pipe at iron shoulder two ends one block is installed respectively.
