Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The invention provides a kind of electric pushrod air-pressure balancing device, using the airway tube on connector through anti-
Water cover piston rod can move up and down in electronic push rod machine body air pressure caused by acting is exported in bucker.When electronic
, will not be because of because gas pressure caused by normal work can be discharged in bucker when push rod body is in Soaking environment
Cause to produce negative air pressure in electronic push rod machine body during the outside output campaign of piston rod, avoid water and be drawn into electronic push away by counter
In bar body.Compared with common water proof type electric pushrod, the electric pushrod air-pressure balancing device in the present invention, carried for electric pushrod
Water-proof function has been supplied, can meet to use under the conditions of commonly drenching with rain, the needs of complete underwater operation environment can also be met so that
Electric pushrod, which has, is more widely applied occasion, and the working life of its own can be extended.It is right below in conjunction with the accompanying drawings
Electric pushrod air-pressure balancing device of the present invention is described in detail.
Refering to Fig. 1, it is shown that the structural representation of electric pushrod air-pressure balancing device of the present invention.With reference to Fig. 1, to this
Invention electric pushrod air-pressure balancing device illustrates.
As shown in figure 1, the electric pushrod air-pressure balancing device of the present invention is arranged on electric pushrod, pushed away for balance electric
The piston rod of bar avoids that environmental liquids are drawn into electricity because of caused positive and negative air-pressure in positive and negative air-pressure caused by up and down motion
In dynamic push rod, so as to cause the failure of electric pushrod.The electric pushrod air-pressure balancing device of the present invention includes connector 21, air guide
Pipe 22 and bucker 23, connector 21 are arranged on electric pushrod body 11, and airway tube 22 is arranged on connector 21, is led
Tracheae 22 is connected by connector 21 with the inner chamber 112 of electric pushrod body 11, the end of airway tube formed set upward it is logical
Gas port 221, bucker 23 are located at blow vent 221, are prevented from intaking at blow vent 221, are played waterproof action.
Airway tube 22 connects the inner chamber 112 of electric pushrod body 11 and the inner space of bucker 23, by electronic push rod machine
Positive and negative air-pressure in body 11 is exported in bucker 23, and specifically, the piston rod 12 in electric pushrod body 11 moves up and down
When, the air pressure in the inner chamber 112 of electric pushrod body 11 can pass through airway tube 22 and the convection current of bucker 23, it can be ensured that electric pushrod
Worked in water.The electric pushrod body 11 being fully sealed can be totally immersed in water, without producing because of electronic push rod machine
Positive and negative air-pressure in the inner chamber 112 of body 11 changes and water is drawn into the phenomenon in electric pushrod body 11 so that electric pushrod has
There is preferable water resistance.
It is preferred that the top of electric pushrod body 11 is provided with seal plug 111, the seal plug 111 ensures electronic push rod machine
The inner chamber 112 of body 11 is closed cavity.Mounting hole and connection mounting hole and electric pushrod body are provided with seal plug 111
The gas passage of 11 inner chambers 112, connector 21 is tightly connected at mounting hole, and then connector 21 is connected with inner chamber 112.
One end of connector 21 is tightly connected with the mounting hole on seal plug 111, and the other end connects with the sealing of airway tube 22
Connecing so that airway tube 22 connects with inner chamber 112, and the airway tube 22 extends from the top of electric pushrod body 11 to bottom, and in
The bottom outward bending of electric pushrod body 11 forms horizontal segment 222, then is folded upward at forming vertical section 223, the vertical section 223
End close to the top of electric pushrod body 11.Vertical section 223 is set parallel with electric pushrod body 11.
Bucker 23 has an openend 231, and the bucker 23 is the enclosed construction with openend 231, relative to opening
The one end at mouth end 231 is blind end 232, and bucker 23 is located on the blow vent 221 of airway tube 22, the openend of bucker 23
231 are set down, and space is installed between blind end 232 and blow vent 221.During installation, bucker 23 is passed through into openend 231
It is set on the blow vent 221 of airway tube 22, blow vent 221 is played a part of by blind end 232 to protect waterproof, blind end
Stayed between 232 and blow vent 221 and set gap, circulated for convenience of the gas of blow vent 221.Electric pushrod body 11 is being placed in water
When being worked in 13, the openend 231 of bucker 23 is located in water 13, and the inside of bucker 23 forms confined air with horizontal plane 131
Between 233, the volume of the confined space 233 and the volume of the inner chamber 112 of electric pushrod body 11 match, to ensure because of negative pressure
When water is sucked in bucker 23, the extreme higher position of rising of the water in bucker 23 will not there be the airway tube in bucker 23
23 blow vent 221, serve the effect of waterproof.
Blow vent 221 is higher than horizontal plane.Water in bucker 23 is because of the influence meeting raising and lowering of air pressure, it is ensured that airway tube
The height of 22 blow vent 221 is higher than the extreme higher position that water rises, and avoids water and enters electric pushrod body from airway tube 22
In 11 inner chamber 112.
With reference to shown in Fig. 2, when being powered, piston rod 12 is moved up and down electric pushrod, and electric pushrod is completely immersed in below
Working condition in water 13 illustrates.
The working condition of electric pushrod is divided into two kinds, and one kind is 12 outside output state of piston rod, and another kind is piston rod
12 inside input states.
Piston rod 12 moves upwards, i.e. 12 outside output state of piston rod, because the inner chamber 112 of electric pushrod body 11 is
Positive confinement environment, the air pressure of the inner chamber 112 reduce, and inner chamber 112 connects the confined space in bucker 23 by airway tube 22
233 so that the pressure in confined space 233 reduces so that water 13 rises in bucker 23, because in electric pushrod body 11
The volume of the volume of chamber 112 and the confined space 233 in bucker 23 matches so that rising of the water 13 in bucker 23
Extreme higher position is less than the height of the blow vent 221 of the airway tube 22 in bucker 23, and water will not be inhaled into airway tube 22, more
It will not enter in the inner chamber 112 of electric pushrod body 11.
Piston rod 12 moves downward, i.e. the inwardly input filling of piston rod 12, because 11 inner chamber 112 is positive confinement ring
Border, the air pressure rise of the inner chamber 112, inner chamber 112 connect the confined space 233 in bucker 23 by airway tube 22 so that close
The pressure rise closed in space 233 so that water 13 declines in bucker 23, and water will not be more entered in airway tube 22.
The use of the air-pressure balancing device of the present invention, fully calculate the gas-solvent of the inner chamber 112 of electric pushrod body 11
The volume of the confined space 233 formed with bucker 23 and horizontal plane 131 matches so that no matter water 13 is being in bucker 23
Do not had the height of the blow vent 221 of the airway tube 22 in bucker 23 during raising and lowering never, and met waterproof
Function.
The electric pushrod air-pressure balancing device of the present invention fully meets water-immersed working environment, also meets the work of rainwater
Make environment, rainwater can be entirely prevented to enter the interior intracavitary of electric pushrod body, there is preferable water resistance.
The present invention is described in detail above in association with accompanying drawing embodiment, those skilled in the art can be according to upper
State and bright many variations example is made to the present invention.Thus, some details in embodiment should not form limitation of the invention, this
Invention will be used as protection scope of the present invention using the scope that appended claims define.
