Application method of the invention is as follows:
Before using pull rod air valve switch, hose can be first passed through, gas source connector 32 is connected with gas source, pneumatic element will be executed
Connector 33 is connected with pneumatic element is executed, and fixing seat 1 is then fixed on sewing device or other equipment by fixed link 2
On, and staff can be foot-operated hinged one of 6 lower end of pull rod, is displaced pull rod by trampling foot-operated mode, passes through foot
After controlling the movement of pull rod 6, it just can vacate both hands and do other things, therefore only need to just can control pull rod using originally idle foot
Air valve switch will not cause any interference to original work, to guarantee working efficiency.
When trampling foot-operated, pull rod 6 can then be moved down along the track of upper slide opening 4 and lower slide opening 5, and upper fixing sleeve 7
With middle fixing sleeve 8 all be set to pull rod 6 on, upper fixing sleeve 7 moves down therewith with middle fixing sleeve 8, when fixing sleeve 8 moves down in the middle, in consolidate
Surely set 8 can then squeeze lower spring 11, and when upper fixing sleeve 7 moves down, upper fixing sleeve 7 then can downwards be carried out pressing piece 13
It squeezes, pressing piece 13 is rotated down centered on itself hinge joint and is squeezed to the exhaust plug 15 to fit with it at this time
Pressure, when the pressing of the depressed part 13 of exhaust plug 15, exhaust plug 15 then can be in retraction to movable span 18 and towards discharge chamber
It is moved in room 19, the activity spacing 31 between exhaust plug 15 and sealing column 24 gradually becomes smaller this moment, and final seal receptacle 29 then can
It is pressed on 24 end face of sealing column, 24 end face of sealing column, which can then cover the venthole 30 on seal receptacle 29, to be sealed, exhaust chamber
19 can not be connected by activity spacing 31, venthole 30 and gas vent 26, as exhaust plug 15 continues towards exhaust plug
It is moved in 15, seal receptacle 29 can then squeeze sealing column 24, make sealing column 24 towards moving in chamber 22 of supplying gas, due to close
It seals 24 diameter of column and is less than 23 diameter of injection well, 25 diameter of sealing plate is greater than 23 diameter of injection well, therefore when sealing column 24 is goed deep into extremely
When supplying gas in chamber 22, sealing plate 25, which no longer covers injection well 23, to be sealed, and exhaust chamber 19 passes through injection well 23 and plenum
Room 22 connects, and gas source connector 32 is connected by hose with gas source, and the high pressure gas of gas source riddles chamber of supplying gas always
In 22, when exhaust chamber 19 penetrates through each other with chamber 22 of supplying gas, high pressure gas can then enter exhaust chamber 19 at the first time
It is interior, it then into executing in pneumatic element connector 33, and under the conveying of hose, enters and executes in pneumatic element, when holding
It, then can be to the execution accurate actuation of pneumatic element when entering appropriate high pressure gas in row pneumatic element.
When exhaust plug 15 is mobile towards 1 direction of the second fixing seat, the first spring 36 is compressed, when sealing column 24 towards
It supplies gas when moving in chamber 22, second spring 39 is compressed, and is if desired closed when executing pneumatic element, need to only be unclamped and be articulated with drawing
6 lower end of bar is ridden, and when pull rod 6 loses external force, the elastic force that compressed lower spring 11 generates can then be such that pull rod resets,
The first spring 36 then can be such that exhaust plug 15 resets by the elastic force that compression generates at the same time, and second spring 39 is generated by compression
Elastic force can then be such that sealing column 24 resets, and when sealing column 24 resets, the sealing plate 25 of 24 end of sealing column is again by injection well 23
Masking sealing, exhaust chamber 19 no longer penetrates through each other with chamber 22 of supplying gas, when the reset of exhaust plug 15, exhaust plug 15 with it is close
Seal has activity spacing 31 again between column 24, the venthole 30 on the no longer plug for seal seat 29 of sealing column 24, exhaust chamber 19
It can then be connected by activity spacing 31, venthole 30 and gas vent 26, executing the gas inside pneumatic element can then pass through
Hose, which enters, to be executed in pneumatic element connector 33, and exhaust chamber 19, activity spacing 31, the entrance of venthole 30 are then passed sequentially through
Into gas vent 26, finally it is discharged outside to from venthole 27, when executing the gas in pneumatic element can smoothly be discharged,
Just it is able to achieve the reset for executing pneumatic element.
When pressing piece 13 moves down pressing by upper fixing sleeve 7, it can be realized and be executed pneumatically by the gas valve starter of upside
Element opens or closes, when pull rod 6 drives extruding seat 14 to move up the progress of exhaust plug 15 to the gas valve starter of downside
When extruding, the actuation for executing pneumatic element can be controlled by the gas valve starter of downside, and downside air valve opening and closing dress
The control principle set is consistent with the above-mentioned control principle of upside gas valve starter, if wanting to realize moving up for pull rod, need to only lead to
Crossing foot just can be realized foot-operated upper lift.
In summary it is found that the present invention can control gas valve starter by pull rod 6, pneumatic element is executed to control
Actuation can open downside gas valve starter when pull rod 6 moves up, and when pull rod moves down, can open upside air valve opening and closing
Device, and upside gas valve starter and downside gas valve starter the execution pneumatic element that can to connect two different, therefore
The movement of pull rod can control the open/close states of two execution pneumatic elements simultaneously, it is not necessary that corresponding air valve switch is in addition arranged,
Control cost is effectively reduced, and with the reduction of component, error rate can be effectively reduced, service performance is enabled to be protected, and draws
The movement of bar 6 just can control by foot, be operated without both hands, when staff is in sewing work, both hands energy
It is enough always ensured that the smooth of cloth, to guarantee the location of the end of a thread, is opened once executing pneumatic element, be performed pneumatic member
