Abstract

A hand starting device comprises a ratchet, a shrouding disc, a restoring torsion spring, a starting wheel, a fixed mandrel and a housing, and is characterized in that a shaft sleeve and a movable bracket are further arranged between the shrouding disc and the ratchet, the shaft sleeve is installed on the center hole of the movable bracket, and a compression spring is installed on the outer ring of the extended portion of the shaft sleeve. As further adopting the movable bracket, the non-working surface contact existed between the movable bracket as a component of the ratchet and the ratchet is eliminated, the problem that a hand starting device fails under low temperature in the past is solved, when the ratchet restores, the movable bracket can limit the displacement of the ratchet causedby the vibration in the mechanical mode, and solves the problem in the past that the hand starting device is damaged by vibration.

Description

The hand starting device

Technical field

The utility model relates to a kind of device of sled motor hand pull starting-up, particularly relates to a kind of hand starting device that can prevent low temperature inefficacy and vibration limits.

Background technique

At present, in the hand pull starting-up device at large-duty engine, the ratchet of homemade its core of hand starting device is released resetting structure and all is made up of shrouding disc (being welded with the inserts of releasing ratchet), ratchet, torsion spring (being used to the ratchet that resets) mostly.This structure is owing to exist design deficiency, causes between the shrouding disc of releasing ratchet work and the ratchet to exist non-working surface contact, and between the two increase of lubricating grease viscosity or the freezing generation of water vapour causes this failure of apparatus after bonding under low temperature environment; This device only depends on torsion spring to reset ratchet and do not have any auto-lock function in addition, and is easily destroyed because of bigger vibrations.

And some other hand starting devices again because of its structural limitations, can not satisfy the high strength requirement of sled large-duty engine adversary starting drive.

Summary of the invention

The purpose of this utility model is to provide a kind of sled motor hand starting device, and this device can not only prevent effectively that low temperature lost efficacy, and because of himself reliable ratchet auto-lock function, can thoroughly solve by the problem of vibration limits.

The purpose of this utility model can reach by following technical measures, it is this hand starting device, comprise stay cord, the wind spring that resets, ratchet, shrouding disc, reduction torsion spring, starter cup, axle sleeve, centration axis and outer cover, its key is: set up an axle sleeve and a travel(l)ing rest between shrouding disc and ratchet; Axle sleeve is contained in the center hole of travel(l)ing rest, on the outer ring of axle sleeve extension stage clip is housed.

Described travel(l)ing rest has three working curved surfaces: what one side was used for the ratchet self-locking for the promotion face that promotes ratchet and use, one side is the reset confined planes of spacing usefulness of travel(l)ing rest from locking face, one side.

The beneficial effects of the utility model are:

Because the existence of this travel(l)ing rest

1, eliminates the non-working surface contact that exists between the parts (travel(l)ing rest) that promote ratchet and the ratchet, solved the problem that hand starting device low temperature in the past lost efficacy;

2, after ratchet resets, its travel(l)ing rest mechanically limits ratchet because of the displacement that vibrations produce, and has solved in the past the hand starting device by the problem of vibration limits.And this model utility is simple in structure.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is the utility model overall construction drawing;

Fig. 2 is a travel(l)ing rest structural drawing of the present utility model;

Fig. 3 is the overall sectional view of the utility model;

Fig. 4 is a work embodiment tectonic maps of the present utility model;

Fig. 5 is the embodiment's of resetting tectonic maps of the present utility model.

Among the figure: 1. shrouding disc, 2. travel(l)ing rest, 3. axle sleeve, 4. stage clip, 5. ratchet, 6. starter cup, 7. outer cover, 8. confined planes, 9. from locking face, 10. reset wind spring, 14. centration axis of promotion face, 11. stay cords, 12. reduction torsion springs, 13..

Embodiment

A kind of hand starting device of the utility model, in outer cover 7, starter cup 6 is connected with outer cover 7 by the centration axis 14 at outer cover center, between starter cup 6 and the outer cover 7 wind spring 13 that resets is housed, ratchet 5 and reduction torsion spring 12 are housed on the starter cup 6, be between ratchet 5 and the shrouding disc 1 that ratchet releases resetting-mechanism, it is characterized in that: travel(l)ing rest 2 and axle sleeve 3; Axle sleeve 3 is contained in the center hole of travel(l)ing rest 2, and stage clip 4 is housed on the outer ring of axle sleeve 3 extensions, for use in postponing travel(l)ing rest 2 rotatablely moving around axle sleeve 3.

In work embodiment shown in Figure 4: starter cup 6 at first is rotated counterclockwise under tension.This moment, travel(l)ing rest 2 was static under stage clip 4 effect, was rotated counterclockwise and with after the promotion face 10 of travel(l)ing rest 2 contacts, travel(l)ing rest 2 is rotated counterclockwise with starter cup 6 until the ratchet on the starter cup 65.Contact with ratchet 5 because of promotion face 10 simultaneously, ratchet 5 is pushed open, finally form working state shown in Figure 4 from reset mode shown in Figure 5.

In the embodiment of resetting shown in Figure 5: starter cup 6 at first turns clockwise under 13 effects of self wind spring.This moment, travel(l)ing rest 2 was static under stage clip 4 effect, turned clockwise and with after the confined planes 8 of travel(l)ing rest 2 contacts, travel(l)ing rest 2 turns clockwise with starter cup 6 until the ratchet on the starter cup 65.Because of contacting with ratchet 5, it can not thrown off voluntarily because of any external force effect simultaneously, finally form reset mode shown in Figure 5 from working state shown in Figure 4 from locking face 9.

Claims
