Description

Technical Field

[0001] The utility model belongs to the technical field of a gasoline engine starter pull disc, and in particular relates to a small gasoline engine starter pull disc. Background Art

[0002] The starting end of a small gasoline engine is equipped with a starting pull disc, and the engine is started by a small amount of starting power provided by the starting pull disc. The existing starting pull disc is generally composed of a pull disc cover, a coil spring, a pull disc, a handle and a pull rope. When in use, the pull rope is pulled out by applying force through the handle. However, since the handle does not have any rebound and shock-absorbing structure, the impact force generated during rebounding hits the end of the pull disc cover, which may cause damage to the pull disc and may also cause damage to internal equipment. For this reason, we propose a small gasoline engine starting pull disc. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 3The utility model provides a technical solution: a small gasoline engine starting pull plate, including a plate cover 1, a fixing seat 2 is fixed on one side of the plate cover 1, a handle 3 is arranged at the end of the fixing seat 2, a pull rope 4 embedded in the plate cover 1 is connected to the end of the handle 3, a starting rebound buffer mechanism is arranged at the end of the handle 3, and an installation guide mechanism is arranged on the inner side of the plate cover 1. The starting rebound buffer mechanism includes:

[0022] A support assembly, which is arranged at the end of the handle 3;

[0023] A connecting component, which is arranged at the connection between the supporting component and the handle 3;

[0024] A guide assembly, the guide assembly being arranged on the inner side of the connecting assembly;

[0025] The shock absorbing component is arranged inside the connecting component.

[0026] In this embodiment, preferably, the support assembly includes a buffer ring 100 arranged at the end of the handle 3 and a through hole 101 penetrating through the surface of the buffer ring 100 , and the through hole 101 is sleeved and connected with the pull rope 4 .

[0027] In this embodiment, preferably, the connecting assembly includes a connecting groove 200 symmetrically opened at the end of the handle 3 and a connecting rod 201 symmetrically fixed at the end of the buffer ring 100, and the buffer ring 100 is conveniently connected to the handle 3 by slidingly connecting the connecting groove 200 with the connecting rod 201.

[0028] In this embodiment, preferably, the guide assembly includes guide grooves 300 symmetrically arranged on both sides of the connecting rod 201 and guide blocks 301 symmetrically fixed on both sides of the inner wall of the connecting groove 200. The guide blocks 301 are engaged with the guide grooves 300 to drive the connecting rod 201 to move and play a guiding role.

[0029] In this embodiment, preferably, the shock absorbing assembly includes a built-in groove 400 opened at the end of the connecting rod 201 and a telescopic spring 401 arranged inside the connecting groove 200 and connected to the built-in groove 400, which is convenient for driving the connecting rod 201 to reset and can also play a role in buffering and shock absorption.
