Specific embodiment
Description is made to the preferred embodiment of the utility model below with reference to the Figure of description provided.
As shown in figure 3, the utility model provides a kind of nozzle component, for locking dispensing apparatus, in locking machine structure, play spiral shell
Silk absorption allows screwdriver bit to be inserted in wherein and turn screw to pick and place the effect of screw.Nozzle component includes hollow connection
Extension bar 1, nozzle 2 and swivel nut 3, the upper and lower ends of this three are opening-like, nozzle 2 and 1 grafting of coupling bar, swivel nut 3 and connection
Extension bar 1 is threadedly coupled and locks nozzle 2.
Coupling bar 1 includes main body 11, is fixed on the interconnecting piece 12 of 11 lower end of main body and is fixed in main body 11 simultaneously opposite
The outwardly extending flange seat 13 of main body 11.The side wall of main body 11 opens up the air pipe interface 14 being connected to inside coupling bar 1, and tracheae connects
For mouth 14 for docking with gas-tpe fitting, interconnecting piece 12 is cylindrical, and screw thread is arranged on outer wall, and inside has inner cavity.Flange seat
Through-hole is offered on 13, can pass through being integrally fixed to 2 component of nozzle on locking machine structure of flange seat 13.It is of course also possible to not
Flange seat 13 is set, 2 component of nozzle is installed by other means.
Swivel nut 3 is rotary structure, and tight lock part 31 and locking portion 32 including annular, locking portion 32 and tight lock part 31 1
It is fixed on tight lock part 31 body formedly, the size of tight lock part 31 and 12 size of interconnecting piece of coupling bar 1 are corresponding, and inner wall is set
There is screw thread, therefore tight lock part 31 can be screwed on interconnecting piece 12 by being threadedly engaged.The internal diameter in locking portion 32 is then slightly larger than
The outer diameter of 1 main body 11 of coupling bar.In addition, the side wall in locking portion 32 is also provided with inside and outside perforative several checknut holes 33, prevent
Loose threaded hole 33 is preferably even number and is oppositely arranged two-by-two.The locking portion 32 of swivel nut 3 is increased for progress one in the present embodiment
Strong structure intensity and be arranged, actually swivel nut 3 only have tight lock part 31 without locking portion 32 be also it is feasible.
Nozzle 2 is also rotary structure, and including connection-peg 21, the positioning region being fixed under connection-peg 21 22 and is consolidated
Adsorption tube 23 under positioning region 22.Wherein, the inner cavity of the interconnecting piece 12 of the shape, size and coupling bar 1 of connection-peg 21
Shape, size are corresponding, and positioning region 22 is annular corresponding with cylindrical interconnecting piece 12, and radial dimension is greater than connection-peg
21, the minimum outer diameter of adsorption tube 23, length longest.
In conjunction with Fig. 4, Fig. 5, the main channel 24 being inserted into for screwdriver bit, the upper end of main channel 24 and grafting are equipped in adsorption tube 23
First 21 inner cavity connection, the lower end of main channel 24 connects a positioning groove 26, accommodates when screw is adsorbed and be positioned at the locating slot
In 26.Known 2 component of nozzle need to cooperate with air extractor, and screw could have been adsorbed by vacuumizing generation negative pressure by air extractor, because
There are the channels for air circulation for this 23 domestic demand of adsorption tube, and the screwdriver bit to avoid main channel 24 from being inserted into blocks, also in adsorption tube
The flat channel 25 that 24 outside of main channel is extended in the same direction and be connected to main channel 24 is set in 23.The quantity in flat channel 25 has
Body is four, and is equably arranged around main channel 24, it is ensured that adsorption tube 23 can smoothly generate negative pressure.The quantity in flat channel 25
Can also be more or less, it is unrestricted.In addition, main channel 24 is pyramidal structure in the present embodiment, radial dimension by with insert
One end that connector 21 connects is gradually reduced to the one end connecting with locating slot 26, and the main channel 24 of this structure, which is conducive to increase, to be walked
Gas gap, is further ensured that adsorption strength.
It, can also the only not no flat construction of taper of setting one in adsorption tube 23 in the case where guaranteeing flat unobstructed
Channel.
Fig. 6 is combined on the basis of Fig. 3, the connection-peg 21 of 2 upper end of nozzle is inserted upwardly into interconnecting piece 12, makes positioning region 22
It is resisted against 12 bottom surface of interconnecting piece upwards and is positioned, connection-peg 21 is matched with the size of interconnecting piece 12, and rolling will not be generated after insertion
It is dynamic, then pass through the limitation of positioning region 22, the positioning between nozzle 2 and coupling bar 1 can be realized well.Then by 3 sets of swivel nut
It tightens onto nozzle 2, and after tight lock part 31 is threadedly engaged with interconnecting piece 12,3 bottom of swivel nut is set to after tightening and inwardly protrudes out
Once circle compressed part 36 be pressed under positioning region 22 upwards, so that nozzle 2 has been locked on coupling bar 1.It is locking at this time
Portion 32 in the checknut hole 33 that usable flat head screw is locked in locking portion 32 and holds out against main body around 1 main body 11 of coupling bar
11, to enhance the installation strength of 3 three's part of coupling bar 1, nozzle 2 and swivel nut, effectively avoid the course of work
Middle nozzle 2 loosens.
The elements such as bearing and circlip, structure, function and the prior art of the part are additionally provided in the inside of 1 upper end of coupling bar
In it is identical, be not described in detail.
Referring to Fig. 7, gas-tpe fitting 9 is inserted in the air pipe interface 14 on coupling bar 1, and air-extractor can pass through coupling bar 1
Inside forms negative pressure in 23 end of adsorption tube to vacuumizing inside nozzle 2.By setting air pipe interface 14 in 2 component of this nozzle
It sets on coupling bar 1 rather than in nozzle in the prior art 2, the position of gas-tpe fitting 9 can be raised, to merge out more
Lower space, prevent from paying gas-tpe fitting and product in the course of work in lock and interfere.Also, it can will be inhaled without tool auxiliary
Nozzle 2 removes replacement, it is only necessary to first back out swivel nut 3, without dismounting tracheae.Screwdriver bit 8 from the upper end of coupling bar 1 be inserted into and it is downward
It extend into adsorption tube 23, screwdriver bit 8 is interlocked with the lifting mould group in locking machine structure, and adsorption tube 23 is criticized when not drawing screw 5
First 8 are located at higher position, and after screw 5 is adsorbed onto locating slot 26 by adsorption tube 23, screwdriver bit 8 declines and is docked on screw 5,
Then screw 5 can be tightened and completes lock and pays movement.
Compared with prior art, 2 component of nozzle of the utility model is provided with connection-peg 21 in nozzle 2 and is inserted into connection
In bar 1 and positioning region 22 is set to support interconnecting piece 12 to realize the positioning of nozzle 2 Yu coupling bar 1, and locking between the two
Then realized by other swivel nut 3, thus can will positioning the two structures distinguish with locking, make the positioning of nozzle 2 not by
Screw thread influences, and position is more accurate, is conducive to the concentricity for improving nozzle 2 and the screwdriver bit being inserted into coupling bar 1, can solve mesh
The difficulty encountered when preceding precision assembly.In addition, nozzle 2 can be replaced arbitrarily, without dismantling tracheae, assisted without tool, only
Swivel nut 3 need to be backed out, Multiple Type screw is suitable for, is more advantageous to maintenance.
Above disclosed is only the preferred embodiments of the utility model, and effect is to facilitate those skilled in the art
Understand and implement accordingly, the interest field of the utility model cannot be limited with this certainly, therefore special according to the present utility model application
Equivalent variations made by sharp range still falls within the range that the utility model is covered.
