The invention is further described with reference to the accompanying drawings and the detailed description.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

Detailed Description

The present invention will be specifically described below by way of examples.

As shown in fig. 1, the embodiment discloses a starter switch, including casing 1, movable iron core 2 and coil winding 3, casing 1 one end is connected with binding post 4, binding post 4 wire connection coil winding 3, coil winding arranges in on the casing 1 inner wall, movable iron core 2 sets up the mesopore position at coil winding 3, dispose push rod 5 on movable iron core 2, be fixed with spacing seat 6 corresponding with movable iron core 2 in casing 1, be equipped with spring groove 61 towards movable iron core 2 on spacing seat 6, be equipped with the perforation on the tank bottom of this spring groove 61, be connected with guide arm 7 at the one end of movable iron core 2, dispose retaining ring 8 after guide arm 7 one end passes from the perforation, be equipped with first spring 9 between spring groove 61 and the iron core, be equipped with second spring 10 between spring groove 61 and the guide arm 7.

The movable iron core 2 is provided with an accommodating groove 21, the tail end of the push rod 5 is arranged in the accommodating groove 21, the opening end of the accommodating groove 21 is provided with a sealing cover 11, and a third spring 12 is arranged between the sealing cover 11 and the tail end of the push rod 5. Through this third spring 12 for certain elasticity has in the time of the output power of push rod 5, makes when propelling movement isolator through the shift fork, in case isolator and engine flywheel appear the contact collision, makes push rod 5 can not be movable along with movable iron core 2, can keep certain elastic standstill, after isolator and engine flywheel meshing, can last the output power, has improved the reliability of its structure, has effectively prolonged its life-span of using.

An outlet matched with the outer diameter of the movable iron core 2 is arranged on the shell 1, and an inner hole and the outlet of the coil winding 3 form a guide hole 13 for the movable iron core 2 to move. By adopting the structure, the movement of the movable iron core 2 can be kept stable, and the transmission stability of the movable iron core is improved.

A limiting groove 14 is further arranged in the housing 1, a contact plate 15 is arranged at the bottom of the limiting groove 14, and the contact plate 15 is located at an interval position in the stroke direction of the guide rod 7. After the power is switched on, the movable iron core 2 retracts, so that the guide rod 7 extends into the limiting groove 14 and finally touches the contact plate 15 to complete the advancing route of the movable iron core, and the structure avoids the excessive advancing of the movable iron core 2, thereby ensuring the meshing fit tightness of the isolator and the engine flywheel.

The guide rod 7 comprises a side 71 with a larger outer diameter and a side 72 with a smaller outer diameter, a limiting step 73 is arranged between the side 71 with the larger outer diameter and the side 72 with the smaller outer diameter, the side 72 with the smaller outer diameter penetrates through the through hole, one end of the second spring 10 abuts against the limiting step 73, and the length of the side 72 with the smaller outer diameter is larger than the interval between the contact plate 15 and the end part of the guide rod 7. The side 72 with the smaller outer diameter of the guide rod 7 can play a role of limiting, and meanwhile, the arrangement of the limiting step 73 can enable the installation of the second spring 10 to be more reliable and convenient, so that the structural reliability of the second spring is further improved.

By adopting the technical scheme, the coil winding 3 can enable the movable iron core 2 to move along the direction of the guide rod 7 after being electrified, meanwhile, the push rod 5 on the movable iron core 2 can output axially and movably, the movable iron core 2 is reset under the dual action of the first spring 9 and the second spring 10 after being powered off, the reset of the movable iron core 2 is ensured by the arrangement of the first spring 9 and the second spring 10, the structure is reliable, and the output of a one-way device on a starter is supported powerfully.

Finally, the working principle is as follows: the coil winding 3 is given in the electrically conductive electricity that gives of binding post 4 circular telegram back, coil cover group produces magnetic force after circular telegram, order about movable iron core 2 to the inboard indentation of casing 1, the shift fork on the starter is stirred in the push rod 5 atress, if the output gear on the isolator meets and bumps the tooth atress, push rod 5 accessible third spring 12 can stretch out in storage tank 21, make can not remove along with movable iron core 2, guide arm 7 can play the spacing effect of stroke, avoid 2 strokes overlengths of movable iron core, after the outage, movable iron core 2 can in time return under the effect of first spring 9 and second spring 10, such structure makes the switch operation of starter more reliable and more stable.
