Abstract

The utility model belongs to the technology field of vehicle control optical signal or lighting device, which discloses a combined switch of farm equipment. The utility model comprises a base box (1), a luminosity-changing ejector rod (3) with active connection inside the base box (1) and extending out from the base box, a handle (4) with the inner end inserted into the luminosity-changing ejector rod (3) and the outer end ling outside the luminosity-changing ejector rod (3), a switch control jacking block (6) connected with the inner end of the handle (4), a luminosity-changing switch (5) arranged inside the base box (1) and contacting with the luminosity-changing ejector rod (3) and the switch control jacking block (6), a steering shifting yoke (2) connected with the luminosity-changing ejector rod (3), a steering switch (8) arranged inside the base box (1) and contacting the steering shifting yoke (2), a boss (9) arranged at the outlet on the upper wall of the base box (1) where connected with a steering wheel shaft, a waterproof and dustproof jacket (10) clipped the shell of the base box (1) and the luminosity-changing ejector rod (3) which arranged at combining site of the luminosity-changing ejector rod (3) and the shell of the base box. The switch can prevent water and dust from entering into the switch, which avoids burnthrough for switch short-circuit and poor contact. The light or signal does not change randomly.

Description

Agricultural machinery light unit switch

The utility model belongs to the technical field of vehicle with the switch of control optical signalling or lighting device.

Present agricultural machinery is because simpler and cruder, be subjected to the influence of factors such as price, general do not have a canopy, therefore its various instrument or various switch all are exposed, the operational environment of agricultural machinery is very abominable again, is in wind and weather and high dust state, and various switches are very easily intake or dust, thereby cause short circuit to burn or loose contact, influence the use of light or signal.And the switch that has is long owing to shift bar, heavy, when travelling, can cause the random change of light or signal on the road surface of jolting, thereby cause the accident.

The purpose of this utility model provides a kind of water proof and dust proof and can arbitrarily not change the agricultural machinery light unit switch of light or signal.

This agricultural machinery light unit switch, comprise the pedestal box, be movably connected in an end in the pedestal box and stretch out the change spire bar of pedestal box, the outer end is the inner movable handle that becomes in the spire bar that inserts outside becoming the spire bar, with the inner switch control jacking block that is connected of handle, be contained in the dimmer switch that contacts with switch control jacking block with change spire bar in the pedestal box, activity is contained in the shift fork that turns to that is connected with change spire bar in the pedestal box, in the pedestal box with the pole changer that turns to shift fork to contact, with the pedestal box upper wall mouth of steering wheel shaft junction on be provided with boss, be provided with the anti-water dust cover that is stuck on pedestal box wall and the change spire bar becoming the confluce of spire bar with pedestal box wall.

Since with the pedestal box upper wall mouth of steering wheel shaft junction on be provided with boss, on boss, buckle lid, be provided with the anti-water dust cover that is stuck on pedestal box wall and the change spire bar in the confluce that becomes spire bar and pedestal box wall, make water, dirt not to enter in the switch, short circuit is burnt and loose contact thereby assurance pole changer and dimmer switch do not occur.It is short thin light to become the spire bar, and when vehicle travelled on the road surface of jolting, becoming the spire bar can be own unmovable, and light signal can arbitrarily not change.

Accompanying drawing shows embodiment of the present utility model, wherein:

Front view cuts open in the office that Figure 1 shows that agricultural machinery light unit switch;

Figure 2 shows that the upward view of agricultural machinery light unit switch;

Front view cuts open in the office that Figure 3 shows that agricultural machinery light unit switch;

Figure 4 shows that the cutaway view Amplified image that becomes spire bar and slide block;

Figure 5 shows that and become spire bar and the annexation enlarged drawing that turns to shift fork;

Agricultural machinery light unit switch as shown in the figure, comprise pedestal box 1, the change spire bar 3 that be movably connected in the pedestal box 1, an end stretches out pedestal box 1, the outer end is the inner movable handle 4 that becomes in the spire bar 3 that inserts outside becoming spire bar 3, with the handle 4 inner switch control jacking blocks 6 that are connected, be contained in the pedestal box 1 and control the dimmer switch 5 that jacking block 6 contacts with becoming spire bar 3 with switch, dimmer switch 5 comprises and becomes the slide block 7 that spire bar 3 contacts with switch control jacking block 6, with sliding fast 7 switch body that are connected 12.Activity be contained in the pedestal box 1 with become that spire bar 3 is connected turn to shift fork 2, with the pole changer 8 that turns to shift fork 2 to contact, activity is plugged with the close lamp switch 11 that contacts with pole changer 8 on pedestal box (1) in pedestal box 1.With the pedestal box 1 upper wall mouth of steering wheel shaft junction on be provided with the boss 9 that is connected as a single entity with pedestal box 1, be provided with and be stuck in pedestal box wall and become anti-water dust cover 10 on the spire bar 3 becoming the confluce of spire bar 3 with pedestal box 1 wall.Turning handle, it is sliding soon on three positions to control jacking block control by switch, and three points of switch are connected, and three kinds of light of conversion vertically rotate and become the spire bar and also control slidingly soon on three positions, make three points of switch connect three kinds of light of conversion.Lateral rotation becomes the spire bar and is switched on or switched off by turning to the fork controls pole changer.

Claims

1, a kind of agricultural machinery light unit switch, comprise pedestal box (1), be movably connected in an end in the pedestal box (1) and stretch out the change spire bar (3) of pedestal box (1), the outer end is the inner movable handle (4) that becomes in the spire bar (3) that inserts outside becoming spire bar (3), with the inner switch control jacking block (6) that is connected of handle (4), be contained in the dimmer switch (5) that contacts with switch control jacking block (6) with change spire bar (3) in the pedestal box (1), activity be contained in be connected with change spire bar (3) in the pedestal box (1) turn to shift fork (2), in pedestal box (1) with the pole changer (8) that turns to shift fork (2) to contact, it is characterized in that with pedestal box (1) the upper wall mouth of steering wheel shaft junction on be provided with boss (9), be provided with and be stuck in pedestal box wall and become anti-water dust cover (10) on the spire bar (3) becoming the confluce of spire bar (3) with pedestal box (1) wall.
