The normal use of column.
Setting spacing between two adjacent tread plates is controlled in 3-5CM, and the setting height of each tread plate is 1-
1.5CM。
It is oriented to hole setting stepped, the diameter of lower end and the diameter of rebound column match so that springing back column can be
Wherein move up and down, and the diameter of upper end then matches with resetting spring, preferably to fix the position of the resetting spring, to keep away
Exempt from resetting spring to occur to slide and influence using effect when in use.
The push-pull rod 5 that the reciprocal trigger device is connected by shaft with 2 front end of lower platen by front end, setting are pushing and pulling
Key 7 is touched in the idler wheel 6 of 5 rear end of bar, the gyro wheeling concrete chuting 9 being arranged below idler wheel 6, and the stop being arranged in gyro wheeling concrete chuting 9
It is formed with free time touching key 8；It is further opened on the parking blend stop 4 and runs through slot with what the gyro wheeling concrete chuting 9 matched.
Push-pull rod will push and pull idler wheel with the up and down motion of lower platen so that idler wheel can be in gyro wheeling concrete chuting
It moves back and forth.Idler wheel will touch stop touching key and idle touching key during movement, and then reach triggering prompt
The purpose of lamp control circuit.
Setting is the normal operation for influencing push-pull rod in order to avoid parking blend stop through the purpose of slot on parking blend stop, with
Ensure the operation fluency of push-pull rod, while can also be cooperated with gyro wheeling concrete chuting to control the direction of travel of idler wheel.
As shown in figure 5, the prompt lamp control circuit is by voltage stabilizing chip U1, monopole double control switch S1, monopole double control switch
S2, antenna N, capacitance C1, capacitance C2, capacitance C3, capacitance C4, capacitance C5, capacitance C6, resistance R1, resistance R2, resistance R3, resistance
R4, light emitting diode D1, light emitting diode D2 compositions.
When connection, one end of capacitance C1 is connected with the Vin pins of voltage stabilizing chip U1, the other end and voltage stabilizing chip U1
GND pins are connected, and capacitance C2 is arranged in parallel with capacitance C1, and one end of capacitance C3 is connected with the Vout pins of voltage stabilizing chip U1
Connect, the other end is connected with the GND pins of voltage stabilizing chip U1, capacitance C4 is arranged in parallel with capacitance C3, one end of resistance R1 with it is steady
The Vout pins of pressure chip U1 are connected, the other end is connected with the ends a of monopole double control switch S1, the poles P of light emitting diode D1
It is connected with the ends c of monopole double control switch S2, the poles N are connected after resistance R2 with the GND pins of voltage stabilizing chip U1, light-emitting diodes
The poles P of pipe D2 are connected with the ends b of monopole double control switch S2, the poles N are connected after resistance R3 with the GND pins of voltage stabilizing chip U1
It connects, one end of inductance L1 is connected with the poles P of light emitting diode D2, the other end is managed after resistance R4 with the GND of voltage stabilizing chip U1

One end is connected with antenna N.
Wherein, the ends b of monopole double control switch S1 are connected with the ends a of monopole double control switch S2, the c of monopole double control switch S1
End is connected with the ends c of monopole double control switch S2, the power input of the both ends of capacitance C1 as the prompt lamp control circuit.Surely
The three terminal regulator for pressing chip U1 selection models LM7812, prompts lamp control circuit to be connected with signal receiver by antenna N
It connects.
Capacitance C1 and capacitance C2 can be very good to complete to be filtered input power, to reduce the fluctuation of voltage,
Electric current after filtering again passes by voltage stabilizing chip U1 and carries out secondary filtering processing, so can be to use electrical component to be subsequent
A metastable power supply environment is provided, to ensure that light emitting diode D1 or light emitting diode D2 can normally be sent out
Light.And the resistance R2 and resistance R3 being arranged are then the drops in order to ensure that light emitting diode D1's and light emitting diode D2 is safe to use
The impact that low light emitting diode D1 and light emitting diode D2 are subject to, further improves the service life of product, reduces product
Frequency of maintenance and use cost.
Color luminous the light emitting diode D1 is green, and color luminous light emitting diode D2 is red, and is shone
Diode D1 and light emitting diode D2 are arranged in the same warning light, which is arranged the top in parking stall 1；Monopole dual control
Switch S1 and monopole double control switch S2 are connected with two mechanical activation devices respectively.
The purpose that monopole double control switch S1 and monopole double control switch S2 is arranged is to promote to enable the vehicle to correctly to complete
It stops, to avoid there is a case where vehicle accounts for two, only after two mechanical activation devices are triggered, can just make monopole
The ends a of double control switch S1 and monopole double control switch S2 are connected with the ends c, so that light emitting diode D2 shines, so that
Warning light is shown as red light, so that other drivers and parking attendant can learn that the vehicle of the parking stall stops a long way off
By situation.
When in use, vehicle enters in parking stall, when vehicle reaches lower platen, the lower platen then because vehicle dead weight and
It moves downward, then pushing rolling wheels slide push-pull rod in gyro wheeling concrete chuting, until idler wheel rolls across stop touching key, roll across and stop in idler wheel
When by touching key, the ends a will then be connected by monopole double control switch S1 with the plectrum of S2 with the ends b, and then switched-on light emitting diodes
D2 makes the display of warning light switch to red light by green light.It is upward under the action of then lower platen is in resetting spring that parking stall is outputed in vehicle
It rises, the ends a will then be connected by the early idle touching key of idler wheel touching, monopole double control switch S1 with the plectrum of S2 with the ends c, in turn
Switched-on light emitting diodes D1 makes the display of warning light switch to green light by red light.
When light emitting diode D2 is connected, inductance L1 and capacitance C5 coordinates so that electric current vibrates, and the oscillator signal is logical
It crosses after capacitance C6 and signal receiver is sent to by antenna N, and finally captured by control centre；Control centre is capturing corresponding letter
After number, sends the signal to navigation large-size screen monitors and carry out real-time display at corresponding parking stall on the screen, to reach so that driving
The person of sailing just can intuitively understand the purpose of vehicle parking situation in parking lot after entering parking lot.
As described above, the present invention can be realized well.
