Detailed Description

As shown in fig. 1 to 6, a novel extension tube spray head mainly comprises an outer sleeve fixing rod, an outer sleeve 4 arranged in the outer sleeve fixing rod and a spray device arranged in the outer sleeve 4; the spraying device consists of a spray head 1, a spray head connecting base 2, a first fixed plastic part 3, an outer sleeve 4, a stainless steel spring 11, an inner water pipe 12, a limiting connecting piece 10, a rubber corrugated pipe 8, a cloth cover 7 and a second fixed plastic part 5; the spray head can be in various forms, such as micro-spray, scattering spray head, etc.; the rubber corrugated pipe is made of ethylene propylene diene monomer material, and the hardness is 50 degrees; adopts ultra-thin, soft and endurance high-quality polyester fiber material.

The upper end of the inner water pipe 12 is connected to the lower end of the nozzle connecting seat 2, and the nozzle 1 is installed at the upper end of the nozzle connecting seat 2; the lower end of the inner water pipe 12 is connected to the limit connecting piece 10; a stainless steel spring 11 is sleeved outside the inner water pipe 12; an inner water pipe 12 sleeved with a stainless steel spring 11 is arranged inside the outer sleeve 4 together, and a limit connecting piece 10 capable of sliding up and down is sleeved in the middle section part inside the outer sleeve 4; the stainless steel spring 11 is used for retracting the inner water pipe 12 back more quickly when the sprinkling irrigation is finished, and simultaneously, the inner water pipe 12 can be ensured to be retracted in place along with the rubber corrugated pipe 8.

As shown in fig. 4, a plurality of axial limiting teeth 401 are axially and uniformly arranged on the inner cavity wall of the outer sleeve 4, and a limiting connecting piece limiting tooth 1001 which is engaged with the axial limiting teeth 401 in a staggered manner and slides is also arranged on the limiting connecting piece 10, that is, the limiting connecting piece limiting tooth 1001 slides up and down in the axial limiting teeth 401, so that the limiting connecting piece 10 slides up and down in the outer sleeve 4; through the cooperation of the axial limiting teeth 401 of the outer sleeve and the limiting connecting piece, the spray head is limited not to change the spraying angle, and the spray head is especially used for rectangular spray heads of road green belts and spray heads with angles of 180 degrees and the like.

The upper port of the rubber corrugated pipe 8 is fixedly arranged on the lower end of the limiting connecting piece 10 through an upper fixing snap ring 9, and the lower port of the rubber corrugated pipe 8 is fixedly arranged on the second fixed plastic piece 5 through a lower fixing snap ring 6; a cloth cover 7 is sleeved outside the rubber corrugated pipe 8; the rubber corrugated pipe 8 and the cloth cover 7 are driven by the limit connecting piece 10 to move up and down; the cloth cover 7 is sleeved on the rubber corrugated pipe 8, mainly for limiting the expansion diameter of the rubber corrugated pipe 8, and the rubber corrugated pipe 8 is prevented from being clamped on the outer sleeve 4 after being expanded, and meanwhile, the rubber corrugated pipe 8 is prevented from being burst due to overlarge expansion.

The first fixed plastic part 3 and the second fixed plastic part 5 are fixedly arranged at the upper and lower ports of the outer sleeve 4 respectively.

The lower port of the second fixed plastic part 5 is a water inlet 13.

As shown in fig. 1 and fig. 2, the working principle of the present invention is: water enters the rubber corrugated pipe 8 through the water inlet 13, and because the water outlet of the spray head 1 is small, the rubber corrugated pipe 8 is rapidly expanded and extended through water pressure at the moment, the spray head 1 connected with the inner water pipe 12 is pushed to extend upwards together, the stainless steel spring 11 is compressed, and the spray head 1 is exposed out of the surface of shrub for spray irrigation so as to meet the requirement of actual spray irrigation; when the sprinkling irrigation is stopped, the water supply is stopped, the rubber corrugated pipe 8 does not have pressure difference to naturally recover, and the water in the inner water pipe 12 is quickly discharged from the spray head 1 under the pushing force of the natural resilience of the stainless steel spring 11, so that the spray head 1 quickly retracts into the bush along with the inner water pipe 12 and the rubber corrugated pipe 8, and the effects of extending out during the sprinkling irrigation and retracting after the sprinkling irrigation is finished are achieved.

The utility model discloses flexible part has adopted rubber bellows 8, leads to the water after, struts the extension with rubber bellows through water pressure, and water service pipe 12 upwards extends in promoting, reaches flexible effect, makes shower nozzle 1 just stretch out from in the bush in the sprinkling irrigation, when stopping supplying water and stopping sprinkling irrigation, automatic withdrawal is hidden to the bush in, uses in municipal garden's bush irrigation, and the mechanization that does not influence is pruned, reaches and hides the effect that the shower nozzle does not influence pleasing to the eye and prevent to destroy.

The utility model has the advantages of it is following:

1. the telescopic shower nozzle can be stably used for a long time by the expansion of the rubber corrugated pipe 8 and the action of the rebound spring of the stainless steel, and the condition that the shower nozzle is not expanded normally due to the blockage of water scale or fine sand can be avoided.

2. The requirement on the water pressure is low, the water pressure can be normally expanded and contracted only by being more than or equal to 0.1Mpa, and the problem that the pressure in many places in municipal water supply is low and the expansion spray head cannot be adopted is solved.

3. The integral structure is simple, the telescopic height can reach more than 25cm, the irrigation device is more suitable for shrub irrigation, and the manufacturing cost is low, so that the irrigation device is more beneficial to wide popularization in municipal garden greening.

4. Through the cooperation of the outer sleeve limiting teeth and the limiting connecting piece, the spray head is limited not to change the spraying angle, and the spray head is especially used for a rectangular spray head of a road green belt and a spray head with an angle of 180 degrees and the like.
