Description
Technical field
The utility model belongs to landscape artificial fountain technical field, particularly relates to automatic rotating water-injection head.
Background technology
The middle swivelling pipe lower end part opening part of present automatic rotating water-injection head is inwardly provided with ring in tube, is enclosed within the lower cover tube opening place among ring in tube and is provided with lower cover pipe outer shroud, in the middle swivelling pipe above lower cover pipe outer shroud encircles in tube.Middle swivelling pipe is when having hydraulic pressure to rotate, and lower cover pipe outer shroud, is relatively rubbed lower cover pipe outer shroud and ring in tube and rotates to pressing down by water, due to lower cover pipe and water inlet pipe, fixes, and middle swivelling pipe is hydraulically driven into automatic rotation.Owing to being to lean on water-pressure sealed between ring in lower cover pipe outer shroud and tube, sealing can not be tight, very easily leaks.And in lower cover pipe outer shroud and tube, ring relatively rubs to rotate and very easily makes annular strain in lower cover pipe outer shroud, tube, also very easily leaks.In addition, in lower cover pipe outer shroud and tube, the friction of the high speed rotating of ring very easily makes ring be depleted, and causes using.So easily the leaking of present automatic rotating water-injection head, easy loss shortcoming, only have about 2 months present automatic rotating water-injection head continuous service life.As the kind automatic rotating water-injection head of replacing not in time, the destruction view that gently leaks, heavy middle swivelling pipe disengaging lower cover pipe causes and can not use.
Summary of the invention
The purpose of this utility model is to provide long service life, and watertight automatic rotating water-injection head.
Design of the present utility model is: have fixed cover and the middle swivelling pipe of the water-stop bearing connection fountain head of waterproof, in the middle of making, swivelling pipe can be water-tight again with respect to fixed cover rotation, and the rolling friction of bearing increases the service life greatly.
Structure of the present utility model is:
Watertight automatic rotating water-injection head, comprises circular upper cover 1, circular lower cover 2, middle swivelling pipe 3, and the two ends of middle swivelling pipe 3 are rotationally connected with circular upper cover 1 and circular lower cover 2 respectively; The sidewall of middle swivelling pipe 3 is provided with a plurality of apopores 4, is connected with rotation spray water pipe 5 on apopore 4; On the sidewall of middle swivelling pipe 3, be also provided with regulating rotary to apopore 6, regulating rotary is connected with regulating rotary to curved pipe 7 on apopore 6, it is characterized in that:
The two ends inner tubal wall of middle swivelling pipe 3 is provided with three trapezoidal ladders, the first ladder is by the inside pipe wall of middle swivelling pipe 3, the 3rd ladder is by the pipe outer wall of middle swivelling pipe 3, the second ladder is in the centre of the first ladder and the 3rd ladder, the tube wall of the first ladder position is thicker than the tube wall of second-order ladder position, and the tube wall of the second ladder position is thicker than the tube wall of the 3rd ladder position.The two ends inner tubal wall of middle swivelling pipe 3 is provided with three trapezoidal ladders, and object is the engagement connection area of the two ends of swivelling pipe 3 in the middle of increasing and circular upper cover 1, circular lower cover 2, and makes engagement connection gap complicationsization, the chance that reduces to leak; And make disc type bearing 8 have chimeric locus.
The upper end engagement connection of circular upper cover 1 and middle swivelling pipe 3, at connecting portion, circular upper cover 1 becomes " Z " font leakproof water surface to contact 15 with the second ladder of middle swivelling pipe 3 with the 3rd ladder, between circular upper cover 1 and the first ladder of middle swivelling pipe 3, is embedded with disc type bearing 8;
The lower end engagement connection of circular lower cover 2 and middle swivelling pipe 3, at connecting portion, circular lower cover 2 becomes " Z " font leakproof water surface to contact 15 with the second ladder of middle swivelling pipe 3 with the 3rd ladder, between circular lower cover 2 and the first ladder of middle swivelling pipe 3, is embedded with disc type bearing 8.
Disc type bearing 8 comprises that upper and lower two opposite faces are comprised of rotation annular element and these two spin of rotating between annular element of ring-shaped depression, and these two are rotated annular element and parallel and be respectively different planes.
The reason that can not leak: two rotation annular elements of disc type bearing 8 above contact with middle swivelling pipe 3 sealings with the circular upper cover 1 of the first ladder position respectively, are even bonded into water-tight structure; Two rotation annular elements of disc type bearing 8 below contact with middle swivelling pipe 3 sealings with the circular lower cover 2 of the first ladder position respectively, are even bonded into water-tight structure.The bearing ball that water in the middle of middle swivelling pipe 3 can only rotate between annular element through two, bearing arrives " Z " font leakproof water surface contact 15, disc type bearing 8 is when rotating, enter the bearing ball that the water of bearing ball is rotated and change hydraulic pressure direction and water pressure, the water pressure of having passed through rolling bearing ball reduces greatly, and the water that these pressure reduce greatly enters " Z " font leakproof water surface contact 15 and will turn the angle of two 90 degree and also have the direction of the middle swivelling pipe 3 change water pressures of rotating not to the direction of leaking; Between the second ladder and the 3rd ladder, will have enough distances is 0.8～2.0 centimetre, makes the middle swivelling pipe 3 rotating that the water in gap between the second ladder and the 3rd ladder is driven into and follows middle swivelling pipe 3 to rotate, and from the gap of the 3rd ladder, does not flow out.
So automatic rotating water-injection head of the present utility model is water-tight, or leaks seldom.Again due to the sliding friction considerably beyond prior art of the durability of disc type bearing 8, automatic rotating water-injection head of the present utility model continuously 10～12 months service life water-tight.
