Description

A kind of swivel joint that is used for water pistol

Technical field

The present invention relates to a kind of parts of water pistol, particularly a kind of swivel joint that is used for water pistol.

Background technology

Common water pistol, its water inlet end is connected on the rod tube of a rigidity, the following termination of rod tube and the aqueduct that tap joins, hand-held rod tube gets final product the eminence that the adversary reaches or sprays water at a distance, but because the restriction of water pistol and this rod tube connection angle, can form the water spray dead angle, cause the inconvenience in the use.For this reason, the patent No. is that the Chinese utility model patent " a kind of bent water pistol " (Granted publication number for CN2492321Y) of ZL01224548.8 provides a kind of body of a gun of spraying water can bend the water pistol that circles round arbitrarily, its structure is, establishing one in the rod tube of a suitable length and an end group with stationary body of suitable caliber has connecing of internal thread and establishes member, wherein this connects and establishes member in the form of a ring and be formed with the anti-skidding decoration of several equidistant annular distribution in the outside, again at the sheathed grip in the outer wall appropriate location of this stationary body, group is established one and is gone out water assembly at this water pistol top again, it is characterized in that: movable rod tube assembly is in position organized the bending deformed metallic rod body of a suitable length admittedly by an inner spout end with suitable overhead kick structure, the other end of this metallic rod body is installed in another inner spout end appropriate location, admittedly organize the inner catheter of suitable length again jointly with collar elements in the overhead kick structure of two inner spout ends, again group establish a flexible flexible outer tube with its two ends respectively with this stationary body with go out water assembly and match and establish.This water pistol can make shower nozzle towards three-dimensional all directions by the soft bar of bending metal, yet, the bending of its shower nozzle realizes by the soft bar of metal because circling round, therefore its angle of bend is limited in scope, generally can only in scope, regulate greater than 90 degree, still restriction and inconvenience to some extent during use, in addition, the soft bar of metal causes fatigue of materials easily and damages after bending repeatedly.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of have adjusting angle and the well-set swivel joint that is used for water pistol in a big way at above-mentioned prior art present situation.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of swivel joint that is used for water pistol is characterized in that including in turn swivel joint, elbow, angle controller; The water side of described swivel joint is inserted the water inlet end of elbow and is connected one in the mode that can rotate mutually with it, and the water inlet end of swivel joint is the water inlet end of whole swivel joint; Described angle controller is involuted and can be rotated mutually by two parts up and down, its water inlet end is positioned at the rear end under the angle controller, and fix with the water side of elbow and be communicated with, its water side be positioned on the angle controller front end and as the water side of whole swivel joint, the plane at the turning cylinder of two parts up and down of described angle controller and the place, bending axis of elbow is perpendicular.

The connected mode that can rotate mutually between described swivel joint and the elbow can adopt various prior aries, wherein in the following manner for good: i.e. having the limbers on the water side panel of swivel joint is connected with the water inlet end of elbow, and have a center through hole, the head of one screw passes this center through hole loosely and is threaded mutually with the joint pin that is arranged on elbow water inlet end corresponding position, the water side panel of swivel joint and can screw be a relative elbow rotation because of being obtained spacingly by the tail flange of screw is folded;

Can on each different angle, locate with the mutual rotation between the elbow in order to make described swivel joint, also the water side panel of swivel joint that can be above-mentioned is provided with a plurality of locating holes of annular spread, and elbow is provided with the reference column that a head inserts one of described locating hole downwards in the corresponding position, the afterbody of reference column has spring to support, described swivel joint can also offer an annular groove on the perisporium of contiguous its water side panel, wherein be embedded with a sealing ring; Certainly the sealing circle also can be fixed on the elbow medial surface in the splicing position of swivel joint and elbow.

The connected mode that can rotate mutually between two parts up and down of described angle controller can adopt various prior aries, wherein in the following manner for good: promptly also have a projection that makes progress under the angle controller, and the top of angle controller have a downward annular wall loosely sleeve on described projection and can rotate mutually, described annular wall middle part is provided with a dividing plate, and have a through hole in the central authorities of this dividing plate, the head of one screw passes this center through hole loosely and is threaded mutually with described projection, the root end face of described annular wall because of by the tail flange of screw folded obtain spacing;

For the mutual rotation between two parts up and down that make described angle controller can be located on each different angle, also can between the root end face of the annular wall on above-mentioned screw tail flange and described angle controller top, be provided with one and stablize pad.On the described angle controller with angle controller under also can be provided with a plurality of locating holes of annular spread on the opposing end faces, and being provided with the reference column that a head upwards inserts one of described locating hole in the corresponding position under the angle controller, the afterbody of reference column has spring to support.

Compared with prior art, the present invention is owing to provide 360 ° of rotations on the transverse plane between swivel joint and the elbow, and provide between the top and the bottom of angle controller on the vertical plane near 360 ° of rotations, both combinations, make water inlet end at pipe joint be connected and under the fixing prerequisite with rod tube, the water side of angle controller still can be towards three-dimensional all directions, thereby realize making the purpose of the universal rotation of water pistol that is connected the angle controller water side; And the design of rotary positioning mechanism, make to use more flexible, and since wherein the neither one parts bent, thereby service life is longer relatively.
