Specific embodiment
Below in conjunction with the attached drawing in embodiment of the present invention, the technical solution in embodiment of the present invention is carried out clear
Chu is fully described by.
Referring to figs. 1 to Fig. 3, the invention proposes a kind of lifting rod locking device 1, including elevating lever 100, fixed cylinder 200,
Electromagnetic valve component 300 and control unit 400, fixed cylinder 200 rise for being arranged elevating lever 100, electromagnetic valve component 300 for locking
Bar 100 drops, and control unit 400 is for controlling electromagnetic valve component 300 in energized state or off-position.
With further reference to Fig. 4, electromagnetic valve component 300 includes valve casing 310, spool 320, push rod 330, electromagnetic coil (in figure
It is not shown) and return springs 340；Valve casing 310 is fixedly installed in the outer wall of fixed cylinder 200；Spool 320 is slidably installed in valve casing
In valve chamber made of 310 encirclements；The first end of push rod 330 is connected with spool 320, and the second end of push rod 330 is through the valve of valve casing 310
Hole 311, fixed cylinder 200 locking hole 201 towards elevating lever 100 stretch out；Return springs 340 are located in valve casing 310 and elasticity
Act on push rod 330；The electromagnetic coil of electromagnetic valve component 300 is installed in valve casing 310, when the solenoid is activated, electromagnetic wire
Circle generates the suction-combining force to spool 320, it is thus evident that electromagnetic coil is installed on the nearly valve opening side of spool 320.
With further reference to Fig. 5, control unit 400 is used to control the on-off of electromagnetic coil, when control unit 400 controls electromagnetism
When coil is powered, magnetic excitation coil is attracted spool 320, and spool 320 drives push rod 330 to move towards elevating lever 100 and with pre-
If pressure press on elevating lever 100, resulting stiction is enough to overcome to liter between push rod 330 and elevating lever 100
The pulling capacity for dropping bar 100, avoids elevating lever 100 from surprisingly extracting out of fixed cylinder 200.Break when control unit 400 controls solenoid valve
When electric, spool 320 or push rod 330 are returned to initial position under the elastic reaction of return springs 340.Control unit 400 is wrapped
The control switch 410 and power supply unit (not shown) for including control circuit (not shown), being electrically connected with control circuit.
The energization or power-off of electromagnetic coil are controlled by the control unit 400 of the lifting rod locking device, it is easy to control
Push rod 330 compresses or far from elevating lever 100, so that locking or release elevating lever 100, the lifting rod locking device 1 are easy to operate
It is convenient.
Referring to Fig. 4 and Fig. 6 to Fig. 9, in a preferred embodiment of the invention, push rod 330 is set perpendicular to elevating lever 100

Slot 351 is adapted with the slot bottom of for pressure tank 101, when push rod 330 presses in for pressure tank 101.In the present invention, latch segment 350
It is threadedly connected to the second end of push rod 330, of course, latch segment 350 can also be fixed on by the way of welding, snapping connection
The second end of push rod 330.
Return springs 340 are a helical spring, and return springs 340 are at compression or tensional state.The first of push rod 330
End is formed with an elastic pressing part 331, and return springs 340 are arranged push rod 330, the first end and elastic pressing part 331 of return springs 340
Offset, the 311 edge inner wall of valve opening of second end and valve casing 310 offsets, after electromagnetic coil is powered, push rod 330 presses on lifting
When bar 100, return springs 340 are at compressive state, after electromagnetic coil power-off, thrust of the push rod 330 in return springs 340
Initial position is returned under effect, the original state of return springs 340 can be compressive state or free state.
In other implementations, the first end of return springs 330 is connected to the first end of push rod 330, resets bullet
Property part 340 second end be connected to the one end of valve casing 310 far from valve opening 311, when electromagnetic coil be powered after, push rod 330 presses on
When elevating lever 100, return springs 340 be in tensional state, when electromagnetic coil power-off after, push rod 330 in return springs 340
Pulling force under be returned to initial position, the original state of return springs 340 can be tensional state or free state.
Referring to figs. 1 to Fig. 4, the invention also provides a kind of lifting lamps, including cabinet 2, lamps and lanterns 3 and above-mentioned elevating lever
Locking device 1, lamps and lanterns 3 are installed on the top of elevating lever 100, and fixed cylinder 200 adheres on the side shell outer wall installation of cabinet 2, fixed
For the locking hole 201 of cylinder 200 towards the outer wall of cabinet 2, it is compatible with valve casing 310 that the side shell lateral direction penetrating of cabinet 2 offers one
Mounting hole 21, valve casing 310 are installed on mounting hole 21, and the valve opening 311 of valve casing 310 is towards the locking hole 201 of fixed cylinder 200.
