Abstract

The utility model provides a gasoline engine initiator, and belongs to the technical field of initiators. The gasoline engine initiator solves the problems that a torsional elastic structure in the prior art adopts a cylindrical spring, too much space is occupied, the integrated height of the initiator is enabled to be increased, at the same time main stressed points of the cylindrical spring are arranged on spring wires at two ends, and the cylindrical spring is prone to losing functions and breaking and the like. The gasoline engine initiator comprises a machine shell, a bracing wire hole is formed in a side wall of the machine shell, a central shaft is arranged inside the machine shell, a launching wheel connected with bracing wires is arranged on the inner side of the central shaft, a launching connecting block is arranged on the outer side of the central shaft, and a torsion spring is arranged between the launching wheel and the launching connecting block. Two ends of the torsion spring are respectively connected with the launching wheel and the launching wheel connecting block, a volute spiral spring capable of enabling the launching wheel to reset is arranged between the bottom of the machine shell and the launching wheel, and the torsion wheel is a vortex-shaped flat spring. The gasoline engine initiator is compact in structural design, small in size, capable of saving assembling space of a gasoline engine, long in service life and the like.

Description

Gasoline engine initiator

Technical field

The utility model belongs to the starter technical field, refers in particular to a kind of gasoline engine initiator.

Background technique

Miniature gasoline engine is widely used on the products such as mowing machine, generator and washing machine, and the starting drive of miniature gasoline engine generally adopts hand-pulling type recoil starter, and it is simple in structure, easy to use.

At present, known hand-pulling type recoil starter also claims from returning the formula starter, its structure is by starting driver chuck, torsion spring, rope sheave, stay cord, handgrip, spiral spring and starter housing are formed, starting driver chuck is that gasoline engine crank connects, turn round bullet and connect startup driver chuck and rope sheave, when starting, the pulling handgrip drives the rope sheave rotation, drive the startup driver chuck by torsion spring, force gasoline engine starting, unclamp handle and by spiral spring stay cord is unrolled to rope sheave, the bullet of turning round of the prior art all is to adopt the cylindricality spring, has taken too much space when whole mechanism design, make the starter whole height increase, the main force bearing point of cylindricality bullet is on the spring thread at two ends simultaneously, and long-term the use easily lost efficacy, fracture influences the normal use of starter.

Summary of the invention

The purpose of this utility model provides that a kind of compact structure, overall volume are little, the gasoline engine initiator of long service life.

The purpose of this utility model is achieved in that

Gasoline engine initiator, comprise casing, offer the backguy hole on the sidewall of casing, be provided with central shaft in the described casing, it is characterized in that: the installed inside of described central shaft has the starter cup, the outside that connect backguy that the startup contiguous block is installed, be provided with torsion spring between starter cup and the startup contiguous block, the two ends of torsion spring is connected with starter cup and startup contiguous block respectively, be provided with the spiral spring that starter cup is resetted between the bottom of described casing and the starter cup, described torsion spring is to be Vorticose plane spring.

In above-mentioned gasoline engine initiator, described torsion spring turns to two discoid spring volumes by a spring thread, and two springs are rolled up stacked setting, and stretch out to two outsides respectively from the inboard two terminations of spring volume.

In above-mentioned gasoline engine initiator, the outer surface of described startup contiguous block is provided with and connects the projection that the gasoline arbor is used.

The utility model outstanding and beneficial technical effects compared to existing technology is:

The utility model is to have utilized Vorticose plane spring, thereby reduced the whole height of starter, cooperate installation better with petrol engine, changed the stressed strong excessively problem in existing cylindricality spring two ends simultaneously, plane spring stressed shared more even when make starting, strengthened integrally-built stability in use, prolonged working life, the utility model overall construction design compactness, volume be little, saved petrol engine assembly space, long service life.

Embodiment

The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-5:

Gasoline engine initiator, comprise casing 1, offer backguy hole 2 on the sidewall of casing, be provided with central shaft 10 in the described casing, the installed inside of described central shaft has the starter cup 3, the outside that connect backguy that startup contiguous block 4 is installed, be provided with torsion spring 6 between starter cup and the startup contiguous block, the two ends 70 of torsion spring 6 is connected with starter cup and startup contiguous block respectively, be provided with the spiral spring 5 that starter cup is resetted between the bottom of described casing and the starter cup, described torsion spring is to be Vorticose plane spring.

The working principle of this starter simply can be: it is reel that backguy drives starter cup 3() rotate, the spiral spring 5 beginning rollings that starter cup is installed between casing, starter cup rotates the twisting torsion spring, then drive to start contiguous block and make gasoline engine starting, the major function of this torsion spring is for avoiding manpower direct pull gasoline engine crank, play elastic buffer, make the start-up operation of petrol engine more laborsaving, make things convenient for, the elasticity releasability of torsion spring has directly influenced the whole service property (quality) of starter.

Above-mentioned torsion spring turns to 7, two springs of two discoid spring volumes by a spring thread and rolls up stacked setting, and stretch out to two outsides respectively from the inboard two terminations of spring volume.

The coiling from inside to outside of spring thread one end, around to required spring holder path length, the inside coiling of spring thread forms spring holder, than the cylindricality spring, the torsion spring height that the utility model adopts is the thickness of two spring threads, has greatly reduced volume, provides more design space to starter.

The outer surface of above-mentioned startup contiguous block 4 is provided with and connects the projection that the gasoline arbor is used.

Above-described embodiment is preferred embodiment of the present utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
