Description
Technical Field
The utility model relates to a manual diesel generator recoil starter production technology, in particular to recoil starter stay cord installation auxiliary device.
Background
The recoil starter is a key part of a small or miniature gasoline and diesel engine and has the function of rapidly pulling a pull rope of the recoil starter to rapidly rotate an engine flywheel of the gasoline and diesel engine so as to drive an engine crankshaft to rotate. For a diesel engine, the rapid rotation of the flywheel enables the compression ratio in an engine cylinder to reach the diesel oil detonation point, so that the detonation of diesel oil in the cylinder is realized, and the normal operation of the diesel engine is further realized; for the gasoline engine, the ignition device is started while the flywheel rotates rapidly, and normal operation of the gasoline engine is further realized. Generally, before and after a small-sized or micro gasoline-diesel engine is started, a pull rope of a recoil starter is wound inside the recoil starter, and after the pull rope is rapidly pulled out, the pull rope needs to be wound and retracted into the recoil starter so as to be pulled next time. In general, a coil spring roulette, a cover, and a rotation shaft are provided in a recoil starter, the rotation shaft is fixedly connected to the center of the cover, and the coil spring roulette is fitted around the rotation shaft and is rotatable along the rotation shaft. The edge of the spring coiling wheel disc is provided with a pull rope groove for winding a pull rope, and the middle part of the wheel disc is provided with a circular concave step; and the space formed by the excircle of the rotating shaft and the edge of the circular concave step of the wheel disc is a cavity for winding the coil spring, namely a coil spring cavity. In a relaxed condition, the wrap spring is mounted on the outside edge of the wrap spring chamber in its natural state with its outside diameter in its natural state matching the inside diameter of the wrap spring chamber (i.e., the inside diameter of the circular concave steps of the disc). The outer end of the coil spring is fixed on the outer edge of the coil spring cavity, and the inner end of the coil spring is fixed on the rotating shaft. When the pulley disc is driven by the pull rope to rotate along the rotating shaft, the coil spring is wound on the rotating shaft and forms a tension state. At this time, the pull rope is loosened, the coil spring returns to a relaxed state, and the pull rope is wound in the pull rope groove of the wheel disc. Thereby, the pulling out and retracting of the pulling rope is realized (see fig. 1 and 2, in the figures, a is a cover body, B is a coil spring wheel disc, a is a pulling rope groove, B is a cover body through hole, and c is a coil spring wheel disc through hole).
In the production process of the recoil starter, the stay cord through hole on the coil spring wheel disc is opposite to the through hole on the cover body in the tensioning state of the coil spring, the cover body and the coil spring wheel disc are stabilized, one end of the stay cord respectively penetrates through the through hole on the cover body and the stay cord through hole on the coil spring wheel disc from the outside to the inside of the cover body, and the end of the stay cord is knotted. Then, the coil spring wheel disc is released to be free from constraint, the coil spring is restored from a tension state to a relaxation state, and the coil spring wheel disc is driven to rotate in the forward direction, so that the pulling rope is wound in the pulling rope groove at the edge of the coil spring wheel disc.
The installation method of the pull rope of the recoil starter in the prior art adopts a manual mode to install, and manually and reversely rotate the coil spring wheel disc under the condition of stabilizing the cover body, so that the coil spring is in a tensioning state, and the cover body and the coil spring wheel disc are relatively fixed by a simple tool. Then, one end of the pull rope penetrates through the cover body through hole and the coil spring wheel disc through hole, the rope end is knotted, the simple tool is removed, the coil spring is restored to the loose state, the coil spring wheel disc rotates in the forward direction, and the pull rope is wound in the pull rope groove. Because the tension of the coil spring is large, time and labor are wasted when the wheel disc of the coil spring is manually and reversely rotated, and the coil spring is dangerous. In addition, when the coil spring is restored to a relaxed state, the speed is high, and the tail end of the pull rope can fly during the winding process, which is easy to cause danger.
Obviously, the installation method of the pull rope of the recoil starter in the prior art has the problems of high labor intensity, low efficiency, potential safety hazard and the like.
