Abstract
The utility model provides a structure for connection between a shell and a nozzle of a water tank. The structure can effectively avoid loose connection, caused by vibration, between the shell and the nozzle, ensure leakproofness of the connection between the shell and the nozzle of the water tank, and prevent liquid from being leaked. The structure comprises the shell and the nozzle and is characterized in that a stepped hole is formed in the shell, the nozzle is in threaded connection with the stepped hole, the lower end face of the nozzle is attached to the stepped face of the stepped hole, a first sealing ring is embedded between the lower end face of the nozzle and the stepped face, a first spigot protruding upwards is arranged on the shell, the nozzle is provided with a radial second spigot, the second spigot abuts against the first spigot, the nozzle is sleeved with a nut, a radial third spigot is arranged at the upper end of a threaded hole of the nut, the nut is in threaded connection with the first spigot, the third spigot is installed on the first spigot in a pressing mode, and a second sealing ring is embedded between the upper end face of the first spigot and the lower end face of the second spigot.
Description
Technical field
The utility model relates to high-pressure water tank device, is specifically related to a kind of linkage structure of housing and water nozzle of water tank.
Background technique
General housing and water nozzle are threaded connection, and be circumferentially wound around raw meal belt and guarantee the sealing connecting, but in situation about being vibrated, the part being threaded is easily loosening at the outside thread of water nozzle, and raw meal belt sealability reduces, and causes leak of liquid.
Model utility content
For the problems referred to above, the utility model has encircleed a kind of linkage structure of housing and water nozzle of water tank, and it can have avoids becoming flexible because of the housing that causes of vibration and being connected of water nozzle, guarantees the sealing that the housing of water tank is connected with water nozzle, prevents leak of liquid.
Its technological scheme is such, a kind of housing of water tank and the linkage structure of water nozzle, comprise housing and water nozzle, it is characterized in that: described housing is provided with step hole, described water nozzle is connected with described stepped hole screw thread, the lower end surface of described water nozzle and the laminating of the step surface of described step hole, and be embedded with seal ring one between the lower end surface of described water nozzle and described step surface, be positioned at the upper end of described step hole, described housing is provided with the seam one of epirelief, described water nozzle is provided with seam two radially, described seam two is resisted against on described seam one, described water nozzle is arranged with nut, the tapped hole upper end of described nut is provided with seam three radially, described nut is threaded with described seam one, and described seam three press-fits on described seam one, between the lower end surface of the upper-end surface of described seam one and described seam two, be embedded with seal ring two.
It is further characterized in that:
Described seam two be circumferentially arranged with seal ring three, the upper and lower end face of described seal ring three respectively with the lower end surface of described seam three, the upper-end surface laminating of described seam one.
The bottom of described water nozzle is frustoconical, and described step hole is provided with the locating face of taper.
Adopt after structure of the present utility model, water nozzle and housing are threaded, and the seam two of water nozzle is resisted against on the seam one of housing, and by nut check, can effectively prevent that the position being threaded because of the water nozzle that causes of vibration and housing is loosening, guarantee the sealing that the housing of water tank is connected with water nozzle; Between the lower end surface of water nozzle and step surface, be embedded with seal ring one, between the lower end surface of the upper-end surface of seam one and seam two, be embedded with seal ring two, seam two be circumferentially arranged with seal ring three, fit with the lower end surface of seam three, the upper-end surface of seam one respectively in the upper and lower end face of seal ring three, further guarantee the sealing that the housing of water tank is connected with water nozzle, prevent leak of liquid.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
