Abstract
The utility model is relates to a connector for telescopic lance boom of sprayer, which comprises an anterior lance boom, a posterior lance boom, positioning piece, sealing and position ring and cover of sealing and position ring. One end of the positioning piece is connected with the open interface of the posterior lance boom, another end connected with the cover of sealing and position ring. Both of the connections are installed sealing and position ring which coordinate with the positioning piece to keep the anterior lance boom and the posterior lance boom in line. The connection is sealed well enough without leakage, and the anterior lance boom does not have friction against the connector directly, thus making extension more free and smooth.
Description
Affiliated technical field
The utility model relates to a kind of jockey of sprayer, and particularly a kind of spray boom is divided into two sections and telescopic spray device and spray boom connector.
Background technology
Its spray boom of sprayer that generally uses is scalable at present, spray boom is divided into two sections of the front and back of different-diameter, its leading portion spray boom diameter is less than the back segment spray boom and be placed in the back segment spray boom, sealing between the spray boom of front and back is by two sealing rings of leading portion spray boom rear sleeve, sealing ring touch back segment spray boom inwall, the connection of the two sections spray booms in front and back adopts the clamp nut on the leading portion spray boom to be threaded with the bell of back segment spray boom front end, and interface does not have encapsulant.This spray boom weak point is that 1. back segment spray boom bells directly are connected with clamp nut, do not carry encapsulant between the two secretly, sealing ring slides in the back segment spray boom, and the connection of two sections spray booms seals inadequately before and after causing, and often occurs leak of liquid in actual use.2. directly friction between the inwall of the outer wall of leading portion spray boom and back segment spray boom and joint when spray boom is flexible, wearing and tearing are big, reduction of service life.
Summary of the invention
The purpose of this utility model provides the flexible spray boom connector of a kind of sprayer, can not leak soup between the spray boom before and after this connector can make, and the inside and outside wall of front and back spray boom and joint does not directly contact.
The utility model is achieved in that a kind of sprayer spray boom connector that stretches, comprise leading portion spray boom, back segment spray boom, keeper, sealing centring ring and sealing centring ring cap, its leading portion spray boom is inserted in the back segment spray boom, it is characterized in that, keeper is placed on the leading portion spray boom, and be threaded with the back segment spray boom, be provided with leading portion spray boom sealing location ring support and corresponding sealing centring ring in its joint, the other end of keeper also is provided with spray boom sealing location ring support and corresponding sealing centring ring, and the sealing centring ring compresses the location by sealing centring ring cap.
Described sealing ring cap front end is provided with a lubricating cup, filling oil absorption material in the lubricating cup.
Because the utility model is provided with sealing centring ring and lubricating cup between the spray boom of front and back, so the joint of front and back spray boom location and good seal performance can seepage liquid during use, lubricated between the spray boom of front and back, flexible more freely, smooth and easy, leading portion spray boom and joint can directly not rub.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model cross-sectional schematic.
In the accompanying drawing 1,1. shower nozzle, 2. spray boom joint, 3. leading portion spray boom, 4. lubricating cup gland, 5. oil cup seat, 6. oil absorption material, 7. sealing centring ring cap 8. seals centring ring, 9. the sealing centring ring, 10. ring support is located in sealing, 11. keepers, 12. sealing location ring supports, 13. back segment spray boom open ports, 14. back segment spray booms, 15. handgrips, 16. positive mouthful of feed tube, 17. ball valves, 18. rubber hose couplings.
The specific embodiment
With reference to Fig. 1, the utility model comprises keeper 11, spray boom sealing centring ring 8,9, keeper 11 and sealing centring ring cap 7 are enclosed within on the leading portion spray boom 3, back segment spray boom 14 front ends are unlimited interfaces 13, open wide interface 13 and be provided with sealing location ring support 12, leading portion spray boom 3 slides into back segment spray boom 14 by opening wide interface 13, keeper 11 rear ends are threaded with unlimited interface 13, there is sealing centring ring 9 junction, compress sealing centring ring 9 when being threaded, keeper 11 other ends also are provided with sealing location ring support 10, are threaded with sealing centring ring cap 7, and also there is sealing centring ring 8 junction, also compress sealing centring ring 8 when being threaded, spray boom two sealing centring rings cooperate with keeper 11 feasible before, the two sections spray boom keeping parallelisms in back.Sealing centring ring cap 7 front ends can have oil cup seat 5, and lubricating cup gland 4 is threaded with oil cup seat 5, is filled with oil absorption material 6 in the lubricating cup, and oil absorption material 6 is inhaled lubricating oil is arranged, and leading portion spray boom 3 is lubricated when sliding in back segment spray boom 14.
In the utility model, sealing location ring support 12 also can be positioned over the rear end of keeper 11, and promptly keeper 11 front and back ends all are provided with sealing location ring support, and the sealing centring ring in the ring support of sealing location is fastening by sealing ring cap and back segment spray boom front end.
When the flexible spray boom jockey of sprayer uses, at first unclamp being threaded of keeper 11 and unlimited interface 13, unclamp keeper 11 again and seal being threaded of centring ring cap 7, leading portion spray boom 3 is extracted out from back segment spray boom 14, twitch is adjusted to the appropriate location, twitch the 6 lubricated spray booms of the oil absorption material in the lubricating cup when regulating spray boom, again two places are threaded and screw, two places connection simultaneously also compresses sealing centring ring 8,9, spray boom before and after two sealing centring rings 8,9 and keeper 11 fit tube are positive, spray boom is in parallel before and after making.Then rubber hose coupling 18 connects the feed liquor flexible pipe, feed liquor flexible pipe 18 other ends are placed in the liquid for jetting, just through rubber hose coupling 18, back segment spray boom 14, the positive mouth 16 of leading portion spray boom feed tube, from shower nozzle 1 ejection, liquid can not leak through back segment spray boom 14 and leading portion spray boom 3 junctions the time liquid at last.
Claims (2)
