The beneficial effects of the utility model: compared with prior art, a kind of abutment wall type shower nozzle that the utility model provides, compact conformation, profile exquisiteness is attractive in appearance, backboard wherein is directly connected with nozzle body, improved the intensity of shower nozzle, make shower nozzle be difficult for breakage under the washing away of current, thereby extended the service life of shower nozzle, meanwhile, temperature-sensing thermal photosensitive elements adopts club shaped structure, has expanded temperature-sensitive area, improve the shower nozzle reaction sensitivity of temperature to external world, thereby be beneficial to, improved early stage combination property and the market competitiveness that suppresses rapid response sprinkler.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model embodiment;
[specific embodiment]
For making the purpose of this utility model, technical scheme and advantage more cheer and bright, below by accompanying drawing and embodiment, the utility model is further elaborated.But should be appreciated that, specific embodiment described herein only, in order to explain the utility model, is not limited to scope of the present utility model.In addition, in the following description, omitted the description to known configurations and technology, to avoid unnecessarily obscuring concept of the present utility model.
Consult Fig. 1, the utility model embodiment provides a kind of abutment wall type shower nozzle, comprise nozzle body 1, backboard 2, splash box 3, adjusting bolt 4, glass bar 5, splash box 3 is fixed at the top of nozzle body 1, the bottom smooth connection of backboard 2 has extends swash plate 6 upwards, swash plate 6 is connected with the nozzle body 1 of splash box 3 belows, and the angle between swash plate 6 and backboard 2 is less than 90 °.Compare with existing shower nozzle, swash plate 6 of the present utility model is directly connected with nozzle body 1, has improved the bulk strength of nozzle body 1, makes shower nozzle be difficult for breakage under the washing away of current, thereby has extended the service life of shower nozzle.
Particularly, the top of nozzle body 1 offers screw 11, adjusting bolt 4 cocks are in screw 11, the bottom of nozzle body 1 offers the through hole 12 passing through for current, the outer surface of nozzle body 1 bottom is provided with the external thread structure 13 that connects water-filled pipe, and nozzle body 1 can be directly connected on the pipeline of automatic sprinkler system.The openend of through hole 12 is provided with nozzle boss 7 that can be movable, and the bottom of glass bar 5 contacts with the upper surface of nozzle boss 7, and the top of glass bar 5 contacts with the bottom surface of adjusting bolt 4.
Embodiment of the present utility model is a kind of abutment wall type shower nozzle that is applicable to ground, and its backboard 2 is fixed on vertical metope, and the axis of nozzle body 1 is parallel with metope, and current upwards can be disperseed effectively, expands the spraying range of current.Meanwhile, acclivitous swash plate 6 dwindles the overall volume of shower nozzle, and the relative altitude of splash box 3 improves, thereby further expands the spraying range of current.
Particularly, the axis of the axis of the axis of splash box 3, screw 11, through hole 12 all with the dead in line of nozzle body 1, the dead in line of the axis of glass bar 5 and adjusting bolt 4, makes the symmetrical configuration of shower nozzle, not only exquisite attractive in appearance, and the reaction speed of the condition of a fire also correspondingly improves to external world.
Particularly, the top of glass bar 5 is spherical, and the bottom of glass bar 5 is needle tubing shape.Embodiment of the present utility model adopts the temperature-sensing thermal photosensitive elements of club shaped structure, and its operating temperature is set as 68 ℃～200 ℃, owing to having increased the temperature-sensitive area of glass bar 5, has therefore improved the reaction sensitivity of shower nozzle.
Further, on the upper surface of nozzle boss 7, offer fixedly blind hole 71, fixedly the diameter of blind hole 71 is less than the diameter of glass bar 5, the fixedly inside of blind hole 71 is located in the bottom of glass bar 5, between the inwall of the bottom of glass bar 5 and fixedly blind hole 71, leave gap, make the bottom of needle tubing shape be fixed on the fixedly inside of blind hole 71, thereby make not cracky of glass bar 5.Simultaneously, the bottom surface of adjusting bolt 4 is cambered surface, the radius of cambered surface is greater than the sphere diameter on the top of glass bar 5, the area that spherical top is leaned on the bottom surface of adjusting bolt 4 greatly reduces, thereby nozzle boss 7 can promptly change position after glass bar 5 is broken, further improved the reaction rate of shower nozzle.
Particularly, the lower surface of nozzle boss 7 offers groove 72, between groove 72 and nozzle body 1, is provided with O RunddichtringO, forms hermetically-sealed construction.
Embodiment of the present utility model is without fire under normal circumstances, and nozzle boss 7 is withstood by glass bar 5 and adjusting bolt 4, and current cannot be spilt; When having the condition of a fire to occur, because indoor temperature is increased to rapidly the operating temperature of glass bar 5, liquid in glass bar 5 expands rapidly, glass bar 5 bursts thereupon, glass bar 5 has now lost supporting role, make nozzle boss 7 lose the sealing function to current, thereby automatically open under the effect of hydraulic pressure, start sprinkling fire.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection domain of the present utility model.
