Abstract

The utility model relates to a rocker-type reverse spray head, which comprises a hollow shaft, and a spray body arranged on the upper side of the hollow shaft, wherein, a rocker shaft, a rocker spring and a fixing part of the rocker spring are arranged in the spray body in which a water spray pipe the same with the hollow shaft is arranged; the front end of the water spray pipe is provided with a nozzle at the front of which a water distributor is arranged, and the spray body is also provided with a reverse component, and therefore, the range of the spray head and the fogging degree for the water can be adjusted according to needs, and the spray head can make fan-shaped sprinkling. The spray head has the characteristics of water saving and easy use.

Description

Rocker-arm commutation shower nozzle

The utility model belongs to rainer, relates in particular to shower nozzle.

Wholecircle rocker-arm bump shower nozzles such as at present domestic PY, the ZY that generally uses, CY, sprinkling irrigation cause to China has played very big effect, but because these shower nozzles can only be done 360 ° wholecircle injection, and fogging degree and jet length can't be adjusted, and therefore this shower nozzle can not be applicable to the sprinkling at limit, field, place, ditch.

The purpose of this utility model then provides a kind of energy and adjusts the rocker-arm commutation shower nozzle that the sprinkling irrigation fogging degree can be done fan-shaped spray again.

The purpose of this utility model is achieved through the following technical solutions: this rocker-arm commutation shower nozzle, comprise hollow shaft, be contained in sprinkler body above it, the positioning element that rocking arm and priming lever spring and priming lever spring are housed on rocker arm shaft, the rocker arm shaft be housed in the sprinkler body, the sparge pipe that communicates with hollow shaft is arranged in the sprinkler body, the sparge pipe front end is equipped with nozzle, is equipped with sprinkler before the nozzle; Be equipped with on the sprinkler body and change same box, the fixed axis that is connected as a single entity with it is arranged in Commutating box, the commutation piece is contained on the fixed axis with reversing bar, commutation piece lower end is solidly installed by upper pin and balance staff, the balance staff lower end has chute, and lower bearing pin is packed in the groove on reversing bar top, and slides in the balance staff chute, the balance staff spring is housed in the balance staff, and baffle plate and rocking arm are fixed together; Hollow shaft is equipped with the back-up ring of band retaining pin outward.

This rocker-arm commutation shower nozzle, in the nozzle front sprinkler is housed, the range and the fogging degree of the water of feasible ejection all can be adjusted as required, reversing arrangement and matching of commutation keeper make this shower nozzle not only can do wholecircle to spray but also can adjust between the retaining pin distance as required and can do fan-shaped sprinkling, use very convenient, if the edge to the plot sprays, adopt this shower nozzle to do fan-shaped sprinkling and get final product, saved a large amount of waters.Therefore use of the present utility model also has bigger social benefit.

Be described further below in conjunction with drawings and Examples.

Fig. 1 is the structure chart of embodiment 1;

Fig. 2 is the structure chart of each parts in the Commutating box in the reversing arrangement among the embodiment 1:

Fig. 3 is the local figure in dress sprinkler position among the embodiment 2:

Fig. 4 is the local figure in embodiment 2 dress back-up ring places.

Embodiment 1: on the top of hollow shaft 9 sprinkler body 13 is housed, rocker arm shaft 15 is housed in the sprinkler body 13; the center line MN of rocker arm shaft 15 and hollow shaft 9 center lines coincide; rocking arm 12 is housed on the rocker arm shaft 15; the axle sleeve 12a that is connected as a single entity with rocking arm 12 is enclosed within on the rocker arm shaft 15; axle sleeve 12a is equipped with cover 19, priming lever spring 14, shaft-cup 16 in the spring outward, pin 17 is fixing with shaft-cup 16.In the sprinkler body 13 sparge pipe 13 ' is arranged, sparge pipe 13 ' communicates with hollow shaft 9, flow straightener 23 is housed in the sparge pipe 13 ', in the sparge pipe 13 ' and the front of flow straightener 23 nozzle 21 is housed, there is sprinkler in the place ahead of nozzle 21, aproll pin in the sprinkler is contained in the hole 20 on the support 20 ' that is connected as a single entity with sprinkler body 13 " in; the hole 20 of the aproll pin 20 and the aproll pin of packing into " be threaded engagement, so that the adjustment of aproll pin 20 upper-lower positions, spring 22 is equipped with in the bottom of aproll pin 20, in this shower nozzle, there is control to spray the changement of angle, on sprinkler body 13, be fixed with Commutating box 10, Commutating box 10 inwalls have the fixed axis 10 ' that is connected as a single entity with it, reversing bar 5 tops are to have 5 ' of flute profile, the bottom is a fork 5 "; balance staff 8 lower ends have chute 8 '; it by upper pin 6 ' with packaged the fitting over of commutation; lower bearing pin 6 slides in balance staff 8 lower end chutes; lower bearing pin is packed in the groove 5 ' on reversing bar 5 tops; balance staff spring 7 is housed in the balance staff 8, and the hole 5a of the upper end of reversing bar upper slot 5 ' and the axis hole 11 ' of commutation on the piece all are contained on the fixed axis 10 ', remove fork 5 " stretch in Commutating box 10 body bottoms, Commutating box 10 tops are exposed on commutation piece 11 tops, and other all place in the box body.Baffle plate 12a in the changement is fixed on the rocking arm 12, baffle plate 12a have on the piece 11 a bit with commutation or some on center line MN any point be on the circumference done of the center of circle.Back-up ring 26 in the changement has two retaining pin 3 for being stuck in the jump ring on hollow shaft 9 excircles in each jump ring.The outside of hollow shaft is with sand control spring 4 its lower ends axle sleeve 1 is housed, and also has packing

ring

2,2 ', 25,13 between axle sleeve and the hollow shaft, and anti-attrition sheet 24 is housed between rocking arm and sprinkler body.

Because the Commutating box 10 in the changement is solidly installed with sprinkler body 13, therefore when water sprayed from nozzle 21, Commutating box 10 rotated with sprinkler body 13, and reversing bar 5, balance staff 8, commutation piece 11 are also along with rotation.After reversing bar 5 is run into retaining pin 3 on the back-up ring 26, reversing bar 5 is around fixed axis 10 ' swing and drive swinging axle 8 swings, compress balance staff spring 7 simultaneously, when balance staff 8 and reversing bar 5 turn over certain angle and stride across the critical point position, under the elastic force effect of balance staff spring 7, make with balance staff and cut with scissors together block 11 mutually around fixed axis 10 ' rotary oscillation, the edge that makes link stopper 11 turns to another side by one side of Commutating box 10, the baffle plate 12a that is fixed together by 11 pairs of blocks and rocking arm 12 stops or decontrols, and make sprinkler body 13, thereby play the purpose of commutation to the different directions running.

Adjust the distance between the retaining pin 3, can reach requirement and spray fan-shaped size.

The height of regulating the nozzle needle 22 of nozzle 21 fronts can be controlled the fogging degree and the jet length of water.
