Fig. 1 is the structural representation of sculping screen water injector in prior art;
Fig. 2 is the structural representation of a kind of detailed description of the invention of sculping screen water injector provided by the present invention.
Detailed description of the invention
Core of the present invention is to provide a kind of sculping screen water injector, and this sculping screen water injector can improve the dismounting efficiency of nozzle and water pipe significantly, improves the service life of nozzle, cost-saving.
In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 2, Fig. 2 is the structural representation of a kind of detailed description of the invention of sculping screen water injector provided by the present invention.
In this embodiment, sculping screen water injector comprises water pipe and nozzle 2, and nozzle 2 comprises the circular joint part be connected with water pipe, is circumferentially provided with groove in the circular joint part of nozzle 2, by clamping part clamping between groove and water pipe; Be between clamping part and groove and between clamping part and water pipe and removably connect.
Concrete, clamping part is U-shaped clamping part, and water pipe is provided with at least two through holes that can insert for U-shaped clamping part.In use, first nozzle 2 is inserted in water pipe, water pipe refers generally to stirrup, then that the groove location of nozzle 2 is corresponding with the position of the through hole of water pipe, is inserted by U-shaped clamping part in the through hole of water pipe, with the groove clamping be positioned on nozzle 2, complete the connection of nozzle 2 and water pipe, U-shaped clamping part easy accessibility, firm to the fixed effect of nozzle 2, easy to process, cost is low.
More specifically, water pipe is provided with four through holes that can penetrate for U-shaped clamping part.Four through holes on water pipe one group between two, position is corresponding, and U-shaped clamping part, first through one group of through hole, through again inserting another group through hole after groove part, makes U-shaped clamping part be fixedly connected with water pipe by nozzle 2 completely.Certainly, when water pipe is provided with four through holes, clamping part also can be two rod-like members, can with the groove clamping of nozzle 2.
In order to realize the clamping of clamping part and nozzle 2, the groove of nozzle 2 is specifically as follows two parallel lines grooves, and the distance between two parallel lines grooves is equal to or slightly less than the distance of the Access Division of clamping part.Article two, parallel lines groove distributes along the circumference of the blank area of nozzle 2, the groove cross section radially of nozzle is the plane that two sections of circular sliding slopes, two line segments are formed, when clamping part is U-shaped clamping part, the distance between two straight-line grooves should be equal to or slightly less than the distance on two limits of U-shaped clamping part.
In use, nozzle 2 rotates in a circumferential direction 180 ° and clamping part can be inserted equally.By above-mentioned setting, clamping part not only by nozzle 2 clamping vertically, can also carry out circumference to nozzle 2 and fix, avoid nozzle 2 to rotate after installation is complete, impact water spray effect.The groove of above-mentioned shape, processing is simple, and the intensity effect for nozzle 2 is less.
Certainly, because the water spray angle of nozzle 2 can to water spray result important, therefore, in order to ensure the diversity of nozzle 2 installation direction, groove also can be square indentations, and namely clamping part just can insert by the every half-twist of nozzle 2, certainly, can also be regular hexagon.About the setting of groove cross section, can ensure that clamping part inserts, and can limits nozzle 2 circumferentially rotate.
Certainly, the design of the groove shapes of nozzle 2 can be selected according to specific needs, such as, when irrigation pressure is larger, in order to ensure that nozzle 2 is connected with firm between water pipe, groove can be the groove of at least two groups along the axial distribution of blank area, and often organizes groove and be square indentations or two parallel lines grooves, namely, when installing nozzle 2, by two clamping parts, nozzle 2 and water pipe are carried out clamping.
Here it should be noted that, the working depth of groove can be selected equally as required, and when depth of groove is larger, the clamping action effect of clamping part is good, but larger to the intensity effect of nozzle 2; When the working depth of groove is more shallow, the intensity of nozzle 2 can ensure, but the snap effect of clamping part to nozzle 2 is poor, therefore in use, should select according to irrigation pressure and Expected Results.
Simultaneously, about the shape of clamping part and groove, be not limited to shape given in the present embodiment, other can realize the shape of the clamping of nozzle 2 and water pipe, but must ensure that clamping part and groove can be with the use of, and needs to nozzle 2 carry out circumference fixing time, clamping part also needs the relatively-stationary snap-fit engagement with groove.
This sculping screen water injector is fast-spliced water injector, by clamping part clamping between nozzle 2 and water pipe, avoid of the prior art being threaded, effectively can improve the fastness between nozzle 2 and water pipe, while avoiding nozzle 2 to be fallen by high pressure water impact, reduce the consumption of nozzle 2 quantity.Meanwhile, nozzle 2 is connected with the clamping part by easy disassembly between water pipe, effectively can improve the efficiency that nozzle 2 is changed and dredged, and saves the production time, improves the organic efficiency of medium.
This water injector solve nozzle 2 in use easily falls, changes nozzle 2 time of defective nozzle 2 or cleaning blocking long, nozzle 2 plastics connecting thread by high pressure water impact easily damaged, recycle the defects such as number of times is few, service life is short, ensure that the rate of recovery of medium, save the production time.Meanwhile, can effectively reduce hand labor intensity, improve operating efficiency, economize expense and reduce expend, has good use value.
Above sculping screen water injector provided by the present invention is described in detail.Apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
