Magnetic attraction, dynamic iron core pushes electromagnetic switch contact closure, to connect institute's control circuit.Due to riding vehicle engine and its group
Part is closer apart from ground, often because of impeded drainage or immersion, muddy water and dust along electromagnetic switch dynamic iron core and guide sleeve
Between gap enter electromagnetic switch inside cavity, pollute electromagnetic switch contact surface, lead to electromagnetic switch poor contact and fail,
Starter can not normally start.
Summary of the invention
The utility model is in order to solve the above-mentioned technical problem, to provide a kind of starter electromagnetism with waterproof construction and open
It closes, can prevent muddy water and dust from entering in electromagnetic switch cavity along the gap of the dynamic iron core of electromagnetic switch and guiding inner room
Portion guarantees electromagnetic switch contact clean degree, normally starts for starter and provides safeguard.
The technical solution of the utility model is：
A kind of starter relay with waterproof construction, including shell, the fixed contact pedestal that is fixedly arranged on outer casing bottom, solid
It is located at movable contact block above fixed contact pedestal set on outer casing inner wall, the movable contact rod that is arranged in movable contact block centre bore, is fixedly arranged on
Movable contact spring of the movable contact rod bottom between movable contact block and fixed contact pedestal, first time between movable contact rod and fixed contact pedestal
Position spring, the electromagnetic coil being fixedly arranged between guide sleeve and shell, is set in guide sleeve the guide sleeve being fixedly arranged at the top of movable contact block
The dynamic iron core slided up and down, the second return spring between dynamic iron core and movable contact block, is characterized in that：In dynamic iron core
Outer circumferential walls are equipped with multiple annular grooves arranged up and down, ring type seal are arranged in annular groove, in dynamic iron core outer circumferential walls
Radial inclined hole that is circumferential uniformly distributed corresponding with annular groove and tilting down, setting radial spring in radial inclined hole, outside radial spring
End abuts against corresponding ring type seal.
Further preferably, it is 30 ° -60 ° that the radial inclined hole, which tilts down angle,.
The utility model has the beneficial effects that：
1, since ring type seal is respectively set in the annular groove of dynamic iron core outer circumferential walls, in dynamic iron core and guide sleeve
Between formed sealing, prevent muddy water and dust along electromagnetic switch dynamic iron core and guiding inner room gap enter electromagnetic switch cavity
Inside guarantees electromagnetic switch contact clean degree, normally starts for starter and provides safeguard.
2, due to the setting in the circumferentially uniformly distributed radial inclined hole corresponding with annular groove of dynamic iron core outer circumferential walls, radial inclined hole
Radial spring, radial spring push ring type seal closely against guide sleeve, further enhance dynamic iron core and guiding inner room sealing
Waterproof effect.
3, since radial inclined hole tilts down, when electromagnetic switch is attracted dynamic iron core movement, dynamic iron core is moved downward, in radial direction
Under spring force effect, ring type seal generates the frictional force opposite with the direction of motion with guiding inner room, and ring type seal is rubbing
It wipes under power effect, moves downward trend with radially inclined hole, to reduce ring type seal and guiding inner room pressure, guaranteeing
While dynamic iron core and guide sleeve clearance seal waterproof, the smoothness that dynamic iron core is attracted movement is improved.
Electromagnetic switch discharge dynamic iron core movement when, dynamic iron core moves upwards, under radial spring pressure, ring type seal with
The frictional force that is generated between guide sleeve 7 and the direction of motion on the contrary, in motion process, ring type seal have radially inclined hole to moving up
Dynamic and deformation trend, ring type seal wedges dynamic iron core and forms angle with guide sleeve, to enhance dynamic iron core and guide sleeve
Between leakproofness.

Specific embodiment
As shown in Figure 1 and Figure 2, a kind of starter relay with waterproof construction, including shell 1, it is fixedly arranged on shell 1
The fixed contact pedestal 2 of bottom is fixedly arranged on 1 inner wall of shell and is located at the movable contact block 3 of the top of fixed contact pedestal 2, is arranged in movable contact block 3
The movable contact rod 4 in heart hole, be fixedly arranged on movable contact spring 5 of 4 bottom of movable contact rod between movable contact block 3 and fixed contact pedestal 2, be set to it is dynamic
The first return spring 6 between contact stem 4 and fixed contact pedestal 2, is fixedly arranged on guide sleeve at the guide sleeve 7 for being fixedly arranged on 3 top of movable contact block
Electromagnetic coil 8 between 7 and shell 1, the dynamic iron core slided up and down in guide sleeve 7, are set between dynamic iron core 9 and movable contact block 3
The second return spring 10, be equipped with multiple annular grooves 11 arranged up and down in 9 outer circumferential walls of dynamic iron core, set in annular groove 11
Ring type seal 12 is set, in the radial inclined hole that 9 outer circumferential walls of dynamic iron core are circumferentially uniformly distributed corresponding with annular groove 11 and tilt down
13, it is 30 ° -60 ° that the radial direction inclined hole 13, which tilts down angle, and radial spring 14, radial spring 14 is arranged in radial inclined hole 13
Outer end abuts against corresponding ring type seal 12.
When electromagnetic switch is attracted the movement of dynamic iron core 9, dynamic iron core 9 is moved downward, under the effect of 14 elastic force of radial spring, annular
The frictional force opposite with the direction of motion is generated between sealing ring 12 and guide sleeve 7, ring type seal 12 is under frictional force effect, tool
Have radially that inclined hole 13 moves downward trend, to reduce pressure between ring type seal 12 and guide sleeve 7, is guaranteeing dynamic iron core 9
While with 7 clearance seal waterproof of guide sleeve, the smoothness that dynamic iron core 9 is attracted movement is improved, while radial spring 14 provides
Ring type seal 12 wear after sealing waterproof compensating action.
When electromagnetic switch discharges the movement of dynamic iron core 9, dynamic iron core 9 is moved upwards, under 14 pressure of radial spring, ring packing
On the contrary, in motion process, ring type seal 12 has radially tiltedly the frictional force and the direction of motion generated between circle 12 and guide sleeve 7
The trend that hole 13 moves up and deforms, ring type seal 12 wedges dynamic iron core 9 and forms angle with guide sleeve 7, to enhance
Leakproofness between dynamic iron core 9 and guide sleeve 7 finally releases the water in dynamic iron core 9 and 7 gap of guide sleeve.
The above are only specific embodiments of the present invention, is not intended to limit the utility model, for this field
Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model,
Any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
