Generator, powder electrostatic gun is mainly by high pressure generator, the body of a gun, nozzle, controller fluidisation powder bucket and auxiliary air device
Deng composition；When carrying out spray coating operations, powder electrostatic gun is connect into negative pole, workpiece grounding (positive pole) structure in high-pressure electrostatic off field
Into loop, powder is sprayed by compressed air by nozzle carries negative electrical charge, sprays on workpiece, completes by principle of opposite sex attraction
To the spray coating operations of workpiece.
Long-term when not in use in powder electrostatic gun, the nozzle of electrostatic gun easily accumulates substantial amounts of dust, can so as to have
The blocking at nozzle can be caused, is unfavorable for spray coating operations next time.
The content of the invention
It is an object of the invention to provide a kind of protective cover for powder electrostatic gun, the advantage is that, can be to powder
The nozzle of electrostatic gun carries out protective effect, avoids the clogging of dust.
The present invention above-mentioned technical purpose technical scheme is that:One kind is used for powder electrostatic gun
Protective cover, the powder electrostatic gun includes gun body and nozzle, and the protective cover is arranged in gun body including circumference array and leaned on
Multiple connection sheets at nearly nozzle, circumference array is provided with multiple tracks rail groove in the gun body, and the connection sheet slides button and is embedded in
In rail groove, and prolong gun body surface and do straight line sliding at nozzle, the connection sheet is rotated close to one end of nozzle and set
There is catch, connected between the catch and connection sheet for obtuse angle.
By using above-mentioned technical proposal, when without using this powder electrostatic gun, connection sheet is slid, makes connection sheet whole
Being slid to nozzle, after catch is away from nozzle, rotate catch so that multiple catch are in simultaneously shrouds shape to nozzle, this
When can realize closed management to nozzle, effectively avoid a large amount of dust rubbish from entering in nozzle.
The present invention is further arranged to：When catch is in nozzle shrouding shape, the catch is close to the surface of nozzle
On be equipped with foam-rubber cushion.
By using above-mentioned technical proposal, in the presence of foam-rubber cushion, the gap that can fill up between catch is further real
Now to the closing at nozzle.
The present invention is further arranged to：The thickness of the foam-rubber cushion is 1-2cm.
By using above-mentioned technical proposal, changing the foam-rubber cushion in size range, can effectively play and fill up between catch
The effect in space, while be not in larger conflict each other, influence catch shrouds Operating In Persistent Current Mode.
The present invention is further arranged to：The gun body is provided with the position-limit mechanism that control connection sheet position is fixed.
By using above-mentioned technical proposal, in the presence of position-limit mechanism, the position control of connection sheet can be effectively realized,
It is set to ensure that position is fixed in working condition and off working state.
The present invention is further arranged to：The position-limit mechanism includes being arranged on the side of connection sheet and away from the company at catch
Spring is connect, the one end of the connecting spring away from connection sheet is fixed with limited block, and the both ends of rail groove are located in the gun body
The contiguous block vertical with rail groove is equipped with, the gap slot set for limited block is equipped with the contiguous block, when limited block is remote
During from gap slot, the connecting spring is in complete compressive state.
By using above-mentioned technical proposal, when needing connection sheet position to fix, connection sheet need to be only slid onto close to scarce
At mouth groove location, limited block is embedded in gap slot automatically in the case where the deformation of connecting spring recovers afterwards, you can quickly to realize
The positioning of connection sheet, ensure that this protective cover is respectively provided with position in working condition and off working state and fixed.
In summary, the invention has the advantages that：
1st, this protective roof structure is simple, easy to operate, can effectively realize the sealing effect to nozzle, prevents a large amount of at nozzle
Dust blocks；
2nd, this protective cover can make up gap between catch by foam-rubber cushion, strengthen the sealing effect to nozzle；
3rd, there is position-limit mechanism on this protective cover, can be in the fixation of working condition and off working state holding position, to protect
The sealing effect to nozzle is demonstrate,proved, while does not interfere with the normal use of this powder electrostatic gun.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
Embodiment 1：A kind of protective cover for powder electrostatic gun, as illustrated in fig. 1 and 2, powder electrostatic gun mainly wraps
Gun body 1 and nozzle 11 are included, this protective cover is arranged on multiple connection sheets 2 in gun body 1 at nozzle 11 including circumference array, and
And circumference array is provided with multiple tracks rail groove 12 in gun body 1, connection sheet 2 is embedded in rail groove 12 by the sliding button of sliding block 121,
And prolong the surface of gun body 1 and do straight line sliding at nozzle 11, rotated provided with catch close to one end of nozzle 11 in connection sheet 2
3, connected between catch 3 and connection sheet 2 for obtuse angle, i.e., catch 3 is heeling condition relative to connection sheet 2.
Embodiment：Under general state, the one end of catch 3 away from connection sheet 2 is in and is delayed obliquely upward shape, i.e., this
When catch 3 gun body 1 will not be contradicted；When without using this powder electrostatic gun, i.e., this powder electrostatic gun is in idle
During state, need to clean out at nozzle 11 first, slide multiple connection sheets 2 simultaneously afterwards, make connection sheet 2 all to nozzle 11
Place's sliding, after catch 3 is away from nozzle 11, rotate catch 3 so that multiple catch 3 to nozzle 11 simultaneously in shape is shrouded, i.e.,
Catch 3 is in the shape that is oliquely downward delayed, due to being obtuse angle connection between catch 3 and connection sheet 2, now multiple structures of catch 3
Shape is shrouded at paired nozzle 11, as shown in Figure 3；Realize to the closed management at nozzle 11, effectively avoid a large amount of dusts
Rubbish enters in nozzle 11.
In the present embodiment, as shown in Fig. 2 when catch 3 is in nozzle 11 shrouding shape, catch 3 is close to nozzle 11
Surface on be equipped with foam-rubber cushion 31, the thickness of foam-rubber cushion 31 is 1-2cm；In the presence of foam-rubber cushion 31, catch 3 can be filled up
Between gap, further realize to the closing at nozzle 11.
