Description

Technical Field

[0001] This utility model relates to the field of engine starting, and in particular to an auxiliary starter. Background Technology

[0002] Auxiliary starters are commonly used equipment in the field of agricultural machinery, mainly used to start engines. Auxiliary starters are divided into three types: hand-cranked, pull-plate type, and electric starter.

[0003] In the existing technology, the common method for hand-cranked auxiliary starters is to use a hand-cranked starter shaft to drive a coiled spring to store energy, and then release the potential energy of the coiled spring through a limiting mechanism to drive the pawl plate connected to the starter shaft to rotate. Several pawls are hinged on the pawl plate. During the rotation of the pawl plate, the pawls rotate and insert the starter cup, which in turn drives the starter cup to rotate, thereby starting the engine.

[0004] The existing methods, such as Chinese patent CN210686171U, have the following technical problems: 1. A friction element is provided outside the starting part of the pawl. The starting part and the friction element will collide during the starting process. Since the friction element is formed by pressing through the pawl plate seat, its strength is low. It is easy to deform during long-term impact, which affects the service life of the product; 2. The stop part of the pawl will collide with the protrusion on the pawl plate. Since the protrusion is directly formed by bending through the pawl plate, long-term impact will cause the protrusion to shift and deform, which will change the rotation range of the pawl during the starting process, causing product damage and affecting the product life; 3. Based on the existing structure, in actual use, after the coil spring has completed energy storage during the start-up process, the crank handle needs to be turned back half a turn to adjust the position of the pawl so that it can be inserted into the starting cup. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a six-claw auxiliary starter to solve the problem in the prior art where product deformation is caused by the impact during the rotation of the pawl, thus affecting the product's lifespan.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a six-claw auxiliary starter, comprising a housing, a starting mechanism disposed on the outside of the housing, the starting mechanism being connected to a main shaft disposed within the housing, a spring housing disposed within the housing, and a spring disposed within the spring housing, characterized in that it further comprises a pawl assembly, the pawl assembly comprising a pawl plate seat, pawls, and a pawl plate cover plate, the pawls being provided with six rotatable circumferentially disposed on the edge of the pawl plate, a hexagonal seat being fixedly disposed on the pawl plate, the pawls comprising a starting part and a stopping part, the stopping part being located between two corners of the hexagonal seat, and the stopping part being able to abut against the hexagonal seat during the start-up process of the auxiliary starter.

[0007] Furthermore, the claw plate seat, hexagonal seat and / or claw plate cover plate are provided with a spindle hole at their center.

[0008] Furthermore, the pawl's starting part and stopping part are connected to the pawl disc by a pin.

[0009] Furthermore, the claw disc is provided with several protrusions, which are used to limit the ratchet during the pawl retraction and opening process.

[0010] Furthermore, the pawl's actuation part is provided with a concave portion and a protruding portion.

[0011] Furthermore, the spindle hole is a rectangular through hole.

[0012] Furthermore, the protrusion is formed by bending it through a claw plate seat.

[0013] Furthermore, the hexagonal base is a rubber component.

[0014] The technical effects of this utility model are: 1. By setting a hexagonal seat on the pawl, the stop part of the pawl abuts against the hexagonal seat during the start-up process. Since the hexagonal seat is fixedly set on the pawl, its impact resistance is much greater than that of the existing technology. Therefore, this solution can effectively improve the service life of the product compared with the existing technology.

[0015] 2. By making the hexagonal base a rubber part, the impact force of the pawl is reduced at the moment of start-up, which plays a buffering role. After the coil spring stores energy, the crank handle does not need to return half a turn. Attached Figure Description

Detailed Implementation

[0019] The following embodiments of this utility model serve as inspiration. Through the following description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The scope of protection of this utility model is not limited to the contents of the claims and description.

[0020] The present invention will be further described with reference to the accompanying drawings: like Figure 1-5 As shown, a six-claw auxiliary starter includes a housing 100, a starting mechanism 200 disposed on the outside of the housing 100, the starting mechanism 200 being connected to a main shaft disposed inside the housing 100, a spring chamber disposed inside the housing 100 containing a spring, and a pawl assembly 300 including a pawl plate seat 310, pawls 320, and a pawl plate cover 330. Six pawls 320 are provided and are rotatably disposed circumferentially on the edge of the pawl plate. A hexagonal seat 340 is fixedly disposed on the pawl plate, preferably a rubber part. The pawls 320 include a starting part 321 and a stop part 322. The stop part 322 is located between two corners of the hexagonal seat 340, and during the start-up process of the auxiliary starter, the stop part 322 can abut against the hexagonal seat 340. By setting the hexagonal base 340 as a rubber part, the impact force of the pawl is reduced at the moment of start-up, which plays a buffering role, and after the coil spring stores energy, the crank handle does not need to return half a turn.

[0021] The starting mechanism 200 is existing technology and is mainly used for storing and releasing the elastic potential energy of the coil spring. During the energy storage process of the coil spring via the starting mechanism 200, the main shaft drives the pawl assembly 300 to rotate, and the pawl 320 is in a retracted position on the pawl plate. When the coil spring has finished storing energy, the elastic potential energy of the coil spring is released via the starting mechanism 200, and the pawl assembly 300 reverses direction. Since the pawl 320 is hinged to the turntable, its rotational speed is relatively high at this time. Under the action of inertia, the pawl 320 extends out of the pawl plate, and the starting part 321 inserts into the engine's starter cup. The stop part 322 abuts against the hexagonal seat 340, driving the engine to start. After the engine starts, its rotational speed is higher than that of the pawl assembly 300, and the pawl 320 retracts into the pawl plate.

[0022] A spindle hole 350 is provided at the center of the claw plate seat 310, hexagonal seat 340, and / or claw plate cover 330. The spindle hole 350 is a rectangular through hole. The pawl 320 is mounted on the claw plate via a pin 323 between its actuating part 321 and its stop part 322. Several protrusions 311 are provided on the claw plate, which are used to limit the pawl 320 during retraction and opening. The protrusions 311 are formed by bending through the claw plate seat 310. The actuating part 321 of the pawl 320 is provided with a concave part 3211 and a protruding part 3212, which facilitates the insertion of the actuating part 321 into the actuating cup.
