The interference of his parts, ultimately results in the shortening of service life.
Utility model content
For the above-mentioned technical problem of prior art, this utility model provides a kind of push rod of multirow process control, such
Push rod can achieve multinode in total kilometres, multirow process control, successfully overcomes technological difficulties it is achieved that multiple-pass node
Control, meet the requirement to lampblack absorber air door folding Angle ambiguity for the client.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions：
A kind of push rod of multirow process control, including sleeve pipe, described sleeve pipe is connected with worm gear seat, is provided with biography in described sleeve pipe
Moving axis assembly and screw component, described transmission shaft component and screw component are connected with each other, and transmission shaft component and screw component
By trapezoidal thread cooperating, drive component is installed in described worm gear seat, described drive component passes through worm and gear
Structure conversion and trapezoidal thread principle drive transmission shaft component work.
Described transmission shaft component includes power transmission shaft and spiral shell, and the two ends of described power transmission shaft are connected to push rod and swivel nut,
Described swivel nut and screw component cooperating.
Described screw component includes screw mandrel, and one end of described screw mandrel is engaged by trapezoidal thread with swivel nut, screw mandrel another
One end is connected with worm gear, described worm gear and drive component cooperating.
Described drive component includes motor, is provided with worm screw in described motor, and described worm and wheel engages.
Described sleeve pipe is provided with casing seat cover plate.
The end of described screw mandrel is provided with screw mandrel fairlead, and described screw mandrel fairlead is located at the inside of worm gear seat.
Described worm screw is provided with worm screw fairlead.
Also include switch module, described switch module includes switching bar, and described switch bar is provided with several strokes
Switch.
The push rod of multirow process control of the present utility model has the advantages that：
1st, general push rod only has one-stroke band point to control, and this utility model multi-section stroke node accurately controls, and speed is uniform,
Time is accurate；
2nd, the margin of tolerance of stall power is little at closing time, and numerical value is accurate；
3rd, good airproof performance, resistance to oil smoke, long service life.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is configuration schematic diagram of the present utility model；
Wherein, 1 it is sleeve pipe, 2 be worm gear seat, 3 be power transmission shaft, 4 be push rod, 5 be swivel nut, 6 be screw mandrel, 7 be worm gear, 8 be
Motor, 9 be worm screw, 10 be casing seat cover plate, 11 be screw mandrel fairlead, 12 be worm screw fairlead, 13 be motor housing, 14 be open

Specific embodiment
With reference to specific embodiment, this utility model is further described, but protection domain of the present utility model is simultaneously
Not limited to this.
As illustrated in fig. 1 and 2, the push rod of multirow process control of the present utility model, including sleeve pipe 1, one end of sleeve pipe 1 is provided with set
Base cover plate 10, the other end of sleeve pipe 1 is connected with worm gear seat 2, is provided with transmission shaft component and screw component in sleeve pipe 1, transmission
Shaft assembly and screw component are connected with each other, and transmission shaft component and screw component pass through trapezoidal thread cooperating, in worm gear seat 2
Drive component is installed, drive component drives transmission shaft component work by worm gear structure conversion and trapezoidal thread principle.
Transmission shaft component in the present embodiment includes power transmission shaft 3, and the two ends of power transmission shaft 3 are connected to push rod 4 and swivel nut
5；Screw component includes screw mandrel 6, and one end of screw mandrel 6 is engaged by screw thread with swivel nut 5, i.e. swivel nut 5 and screw mandrel 6 cooperating, silk
The other end of bar 6 is connected with worm gear 7, and the top of screw mandrel 6 is provided with screw mandrel fairlead 11；Drive component includes motor 8, outside motor 8
Portion is provided with motor housing 13, and motor 8 is connected by riveting with worm screw 9, is provided with worm screw fairlead 12 inside worm gear seat 2, worm screw 9 with
Worm gear 7 engages.
This utility model also includes switch module, and described switch module includes switching bar 14, and switch bar 14 is provided with
Several travel switches 15.During use, switch bar 14 is provided with multiple micro-travel switch positions, is combined into switch module and is loaded on set
In pipe 1 relevant position, during operation, swivel nut 5 side is provided with a fork, when transmission shaft component moves at switch, swivel nut 5 fork meeting
