Vibration.
In initial position, lower sliding block 63 is located at the foremost position of lower slide slot 6, drives gear wheel 91 and the second tooth
Edge wheel 32 is in disengaged condition, and skid 65 stretches out slotted eyes 11 positioned at propping up on block 5, and upper sliding block 71 is located at upper slide slot 7
Last end position, rotation prevention portion 73 and the first gear wheel 31 are in occlusive state, at this point, with first at the upper end of central gear wheel 8
Be engaged at the front end of tip edge item 72, at the lower end of central gear wheel 8 be engaged at the rear end of the second tip edge item 64, billboard 100
In can not turn state;
When needing to adjust the pivot angle of billboard 100, electric 61 work of favourable turn of first control, under 61 offer kinetic energy of electricity favourable turn drives
Sliding block 63 slides backward, and the second tip edge item 64 slides backward also with lower sliding block 63 and drives central 8 turn of gear wheel, from
And drive upper sliding block 71 to slide forward by central gear wheel 8, until lower sliding block 63 slides into the rearmost end position of lower slide slot 6
It sets, upper sliding block 71 slides into the foremost position of slide slot 7, controls electricity favourable turn 61 and stops working, at this point, driving gear wheel
91 and second gear wheel 32 be in occlusive state, skid 65 retracts slotted eyes 11 with live wire and switch and is located at operation chamber 2
Interior, rotation prevention portion 73 and the first gear wheel 31 are in disengaged condition, billboard 100 be in can turn state, then control the first electricity
9 work of favourable turn provides kinetic energy by the first electricity favourable turn 9 and drives 92 turn of gear wheel to drive 32 turn of the second gear wheel, the
Two gear wheels, 32 turn drives 100 turn of billboard so as to adjust the pivot angle of billboard 100, when billboard 100 is adjusted to need
Pivot angle when control the first electricity favourable turn 9 stop working, slotted eyes 11 is retracted with live wire and switch by skid 65 and is located at
It can prevent billboard 100 from causing to pull damage to live wire and switch when adjusting pivot angle in operation chamber 2, then, control electricity favourable turn
61 work reversions drive upper sliding block 71 and lower sliding block 63 to slide into initial position, to pass through rotation prevention portion to provide kinetic energy
It adjusts 100 pivot angle of billboard for 73 pairs to lock, prevents 100 turn of billboard from the offset of pivot angle occurs.At this point, skid 65
Slotted eyes 11 is stretched out again positioned at propping up on block 5, in order to operate the live wire and switch on skid 65.
The beneficial effects of the present invention are:
1. being located at the foremost position of lower slide slot by lower sliding block, drives gear wheel and the second gear wheel to be in and disengage
State, skid stretch out slotted eyes positioned at propping up on block, and upper sliding block is located at the last end position of upper slide slot, rotation prevention portion and first
Gear wheel is in occlusive state, at this point, at the upper end of central gear wheel be engaged at the front end of the first tip edge item, central tip edge
Be engaged at the lower end of wheel at the rear end of the second tip edge item, billboard be in can not turn state, therefore can be to the rotation of billboard
It is dynamic to be locked, prevent billboard turn from the offset of pivot angle occurs, and at this point, being easy to use outside live wire and switch exposing body
Person's operation, props up skid using block is propped up, increases the bearing capacity of skid, prop up the detachable setting of block,
Reduce the occupancy for propping up block for space;
2. electricity favourable turn provides kinetic energy and lower sliding block is driven to slide backward, the second tip edge item by control electricity favourable turn work
Central gear wheel turn is driven as lower sliding block slides backward, thus from sliding block in central tip edge wheel drive to advancing slip
Row, until lower sliding block slides into the last end position of lower slide slot, upper sliding block slides into the foremost position of slide slot,
Control electricity favourable turn stops working, at this point, gear wheel and the second gear wheel is driven to be in occlusive state, skid with live wire with
Switch retracts slotted eyes and to be located at operation intracavitary, and rotation prevention portion and the first gear wheel are in disengaged condition, and billboard is in can turn shape
State then controls the first electricity favourable turn work, provides kinetic energy by the first electricity favourable turn and drive gear wheel turn to drive the second tooth
Edge wheel turn, the second gear wheel turn drives billboard turn to facilitate the pivot angle of adjustment billboard, when billboard is adjusted to
The first electricity of control favourable turn stops working when the pivot angle needed, and the pivot angle adjustment of billboard finishes at this time, realizes the pendulum of billboard
Angle adjust automatically, by skid with live wire and switch retract slotted eyes be located at operation it is intracavitary prevent billboard adjustment put
Live wire and switch are caused when angle to pull damage.
3. overall structure of the present invention is simple, manufacturing cost is cheap, structure safety and stability, it can be achieved that billboard pivot angle it is automatic
The pivot angle of automation control adjustment billboard is realized in adjustment and locking, meets existing people for billboard adjustment pivot angle
Demand, it is simple to operate, the pivot angle of billboard can also be accurately adjusted by the angle modulation plate of setting, and it is accurate to increase adjustment
