Also or can effectively fix position shield structure or volume it is larger, safety inconvenient to use.Such as: Chinese patent Shen
Please notification number CN107930928A, apply April 20 2018 day for announcing, invention and created name be a kind of high-pressure micro-mist dust suppression spray
Mouth protective cover, including fixed lid, high-pressure micro-mist dust suppression nozzle and protective cover, disadvantage is that, which is fixed structure,
Nozzle guard cover can not move, and hinder the daily maintenance and maintenance of nozzle, safety inconvenient to use.
Utility model content
The utility model in order to solve it is in the prior art reality production used in nozzle guard cover be usually turn over
Lid formula or slide rail type, when use, can not effectively fix the position of protective cover, be easy to happen loosening, cause using upper inconvenience
With it is dangerous, also or can effectively fix position shield structure or volume it is larger, safe deficiency inconvenient to use,
Can effectively be fixed when providing a kind of flip lid the position of protective cover, be not susceptible to loosen, bascule it is small and stablize, user
Just safe a kind of self-locking type nozzle guard cover.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of self-locking type nozzle guard cover, the protective cover side plate of protection cowl top panel and side including top, the protection
The top of cowl top panel and the head plate of molding machine are rotatablely connected, and are rotated between the protective cover side plate and head plate by nozzle casing limit plate
Connection, the nozzle casing limit plate are equipped with self-locking guide groove.The nozzle guard cover of the utility model is rotatably connected on the head of molding machine
Plate side, nozzle guard cover can be rotated upwardly and downwardly along protection cowl top panel, nozzle casing limit plate is connected on protective cover side plate, for limiting
Determine nozzle guard cover to rotate along the self-locking guide groove on nozzle casing limit plate, the other end of nozzle casing limit plate and the head of molding machine
Plate rotation connection, when working condition, due to self weight, nozzle guard cover is in close state；When protective cover to be opened, nozzle casing
Limit plate rotates upwards, and nozzle guard cover is slided along self-locking guide groove, when being opened to upper end limiting condition, nozzle casing limit plate
Since self weight is sunk, protective cover side plate enters another self-locking guide groove and this self-locking structure, thus effectively fixed protective cover
Position is not susceptible to loosen, and bascule is small and stablizes, safety more convenient to use.
Preferably, the outer wall of the protective cover side plate is fixedly connected with screw loop bar, one end of the screw loop bar is worn
Cross self-locking guide groove.Screw loop bar is for connecting protective cover side plate and nozzle casing limit plate, by screw loop bar certainly
The moving position in guide groove is locked to limit the position of nozzle guard cover.
Preferably, the self-locking guide groove includes the guide chute communicated and self-locking sliding slot, the guide chute and from
Self-locking drift angle is formed between lock sliding slot.Nozzle guard cover is rotated upwardly and downwardly along self-locking sliding slot, when screw loop bar is got over from guide chute
When crossing self-locking drift angle, nozzle casing limit plate is sunk due to self weight enters self-locking sliding slot, limits nozzle guard cover further occurrence
Rotation, the position of effectively fixed protective cover, is not susceptible to loosen.
Preferably, being socketed with anti-attrition sleeve gasket on the screw loop bar.Anti-attrition sleeve gasket is by screw loop bar and self-locking guide groove
Between sliding friction be changed into rolling friction, reduce abrasion and fever, service life improves, and use is also safer.
Preferably, offering radiator window on the protection cowl top panel.Radiator window is used to distribute the heat of nozzle sending, prevents
Only nozzle guard cover is heated excessively damages.
Therefore, a kind of self-locking type nozzle guard cover of the utility model has the advantage that and can effectively fix when flip lid
The position of protective cover, be not susceptible to loosen, bascule it is small and stablize, be used conveniently and safely.

Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Fig. 1,2,3,4,5, a kind of self-locking type nozzle guard cover, in which:
A kind of self-locking type nozzle guard cover, the protective cover side plate 2 of protection cowl top panel 1 and side including top, protective cover
The top of top plate and the head plate 3 of molding machine are rotatablely connected, and are connected between protective cover side plate and head plate by the rotation of nozzle casing limit plate 4
It connects, nozzle casing limit plate is equipped with self-locking guide groove.The nozzle guard cover of the utility model is rotatably connected on the head plate side of molding machine,
Nozzle guard cover can be rotated upwardly and downwardly along protection cowl top panel, nozzle casing limit plate is connected on protective cover side plate, for limiting nozzle
Protective cover is rotated along the self-locking guide groove on nozzle casing limit plate, and the other end of nozzle casing limit plate and the head plate of molding machine rotate
Connection, when working condition, due to self weight, nozzle guard cover is in close state；When protective cover to be opened, nozzle casing limit plate
Rotation upwards, nozzle guard cover is slided along self-locking guide groove, and when being opened to upper end limiting condition, nozzle casing limit plate is due to certainly
Sinking again, protective cover side plate enters another self-locking guide groove and this self-locking structure, thus the position of effectively fixed protective cover, no
It easily loosens, and bascule is small and stablizes, safety more convenient to use.The outer wall of protective cover side plate is fixedly connected with spiral shell
Loop bar 5 is followed closely, one end of screw loop bar passes through self-locking guide groove.Screw loop bar is used to connect protective cover side plate and nozzle casing limit plate
It picks up and, the position of nozzle guard cover is limited by moving position of the screw loop bar in self-locking guide groove.Self-locking guide groove
Including the guide chute 6 and self-locking sliding slot 7 communicated, self-locking drift angle 8 is formed between the guide chute and self-locking sliding slot.Nozzle is protected
Shield is rotated upwardly and downwardly along self-locking sliding slot, when screw loop bar crosses self-locking drift angle from guide chute, nozzle casing limit plate due to
Self weight, which is sunk, enters self-locking sliding slot, limits the rotation of nozzle guard cover further occurrence, and the position of effectively fixed protective cover is not easy
It loosens.Anti-attrition sleeve gasket is socketed on screw loop bar.Anti-attrition sleeve gasket rubs the sliding between screw loop bar and self-locking guide groove
Wiping is changed into rolling friction, reduces abrasion and fever, and service life improves, and use is also safer.It is offered on protection cowl top panel
Radiator window 9.Radiator window is used to distribute the heat of nozzle sending, prevents nozzle guard cover is heated from excessively damaging.
A kind of self-locking type nozzle guard cover of the utility model can effectively fix the position, no of protective cover when having flip lid
The beneficial effect that easily generation loosens, bascule is small and stablizes, is used conveniently and safely.
