Abstract
The utility model relates to the technical field of motor, especially a kind of engine start hand handle with damping mechanism is related to, the handle comprising pull bar and be connected with one end of pull bar, pull bar is provided with the stay cord hole running through its two ends, the position that handle matches with stay cord hole is provided with the rope groove be communicated with stay cord hole, the rubber buffer seat sealing with rope groove and combine is provided with in described rope groove, rubber buffer seat is provided with the penetration hole running through both sides, side corresponding with stay cord hole on rubber buffer seat is provided with the messenger hole communicated with described penetration hole, the axis in messenger hole and the axes intersect of penetration hole or perpendicular.Advantage is: the time lag making stay cord bear large impact pulling force from not stressing to extends 6 ~ 10 times, and the danger that stay cord is pulled off reduces, and is also a directed closed device simultaneously, stay cord tieing can be isolated from the outside, avoids fag end aging.
Description
Technical field
The utility model relates to the technical field of motor, especially relates to a kind of engine start hand handle with damping mechanism.
Background technique
Mini engine needs manually to pull usually starts starting manually, hand handle is directly connected with starting stay cord, stay cord drives rope sheave to rotate in starting, rope sheave drives engine flywheel synchronous rotary again, engine flywheel is due to huge inertia, order about the crankshaft-link rod synchronous rotary of motor, the rotation of flywheel simultaneously makes again igniter start combustion chamber of air cylinder's igniting, and motor just starts to have run well.But existing traditional startup device has many drawbacks: (1) stay cord with rise start being directly rigidly connected, make stay cord often bear moment impact pulling force, have the danger be pulled off; (2) stay cord is due to the cause of production technology, after mostly being tied a knot, is directly exposed in air, and fag end can shorten the life-span because of aging.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of time lag prolongation 6 ~ 10 times making stay cord bear large impact pulling force from not stressing to, the danger that stay cord is pulled off reduces, also be a directed closed device simultaneously, stay cord tieing can be isolated from the outside, avoid the engine start hand handle with damping mechanism that fag end is aging.
For realizing above-mentioned object, the utility model provides following technological scheme:
A kind of engine start hand handle with damping mechanism, the handle comprising pull bar and be connected with one end of pull bar, pull bar is provided with the stay cord hole running through its two ends, the position that handle matches with stay cord hole is provided with the rope groove be communicated with stay cord hole, the rubber buffer seat sealing with rope groove and combine is provided with in described rope groove, rubber buffer seat is provided with the penetration hole running through both sides, side corresponding with stay cord hole on rubber buffer seat is provided with the messenger hole communicated with described penetration hole, the axis in messenger hole and the axes intersect of penetration hole or perpendicular.
The utility model is set to further: be provided with metallic shim in described penetration hole, the hole of metallic shim and the axes coincide in described messenger hole.
The utility model is set to further: in described penetration hole, the sidewall corresponding with messenger hole is the straight sidewall matched with the flat face of metallic shim.
The utility model is set to further: the described rope groove side corresponding with stay cord hole is provided with reducing groove, and described rubber buffer seat is provided with the necking end matched with reducing groove.
The utility model is set to further: the stay cord hole of the other end of described pull bar is by the horn-like hole in decreasing pore size in stay cord nose end mouth to hole.
By adopting technique scheme, the technique effect that the utility model reaches is: design one and start being the on all four rubber part of rope groove attachment face profile with rising, namely the rubber buffer seat combined is sealed with rope groove, again penetration hole is set on rubber buffer seat, for placing stay cord head, the time lag making stay cord bear large impact pulling force from not stressing to extends 6 ~ 10 times, the danger that stay cord is pulled off reduces, also be a directed closed device simultaneously, stay cord tieing can be isolated from the outside, avoid fag end aging; In order to strengthen cushioning effect, rise start between a yielding rubber and stay cord head design a metallic shim, metallic shim can not be out of shape because of the impact external force of stay cord head, but also has increased the compression lifting surface area of starting yielding rubber, ensure that rubber life-span and stay cord head damper mass.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is detonation configuration schematic diagram of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
Embodiment
With reference to Fig. 1, 2, a kind of engine start hand handle with damping mechanism disclosed in the utility model, one end of pull bar 10 is connected with handle 11, pull bar 10 is provided with the stay cord hole 12 running through its two ends, the position that handle 11 matches with stay cord hole 12 is provided with the rope groove 13 be communicated with stay cord hole 12, seal with rope groove 13 in rope groove 13 combine be provided with rubber buffer seat 14, rubber buffer seat 14 is provided with the penetration hole 15 running through both sides, side corresponding with stay cord hole 12 on rubber buffer seat 14 is provided with the messenger hole 16 communicated with described penetration hole 15, the axis in messenger hole 16 and the axes intersect or perpendicular of penetration hole 15.Because rubber buffer seat 14 top is totally enclosed, configuration design also and rise and start the rope groove 13 of handle and mate, is started, inside, to be isolated from the outside, to ensure that stay cord head not easily ageing failure so stay cord head can be wrapped in completely.
In above-mentioned, in penetration hole 15, be provided with metallic shim 17, the hole of metallic shim 17 and the axes coincide in described messenger hole 16.Metallic shim is set and can strengthens shock-absorbing capacity, if fag end directly contacts with rubber buffer seat 14, when Long-Time Service, then appear in transient starting and the rubber mouth in messenger hole is expanded, cause stay cord head directly to be moved to starting handle base portion, rise like this and start just losing pooling feature; Metallic shim 17 can not be out of shape because of the impact external force of stay cord head, but also has increased the compression lifting surface area of starting yielding rubber, ensure that rubber life-span and stay cord head damper mass.Sidewall corresponding with messenger hole 16 in penetration hole 15 is the straight sidewall matched with the flat face of metallic shim 17.Rope groove 13 side corresponding with stay cord hole 12 is provided with reducing groove, and described rubber buffer seat is provided with the necking end matched with reducing groove.The stay cord hole of the other end of described pull bar 10 is by the horn-like hole in decreasing pore size in stay cord nose end mouth to hole.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
