Abstract
The invention provides a connecting structure of a shell and a water nozzle of a water tank, which can effectively prevent the connecting looseness between the shell and the water nozzle caused by the vibration, guarantees the connecting tightness between the shell and the water nozzle of the water tank, and prevents the liquid leakage. The connecting structure comprises a shell and a water nozzle, and is characterized in that a step hole is formed in the shell, wherein the water nozzle is in threaded connection with the step hole; the lower end surface of the water nozzle is bonded with the step surface of the step hole; a sealing ring 1 is embedded between the lower end surface of the water nozzle and the step surface; a stop port 1is upwards projected on the shell at the upper end of the step hole; a radial stop port 2 is formed in the water nozzle, and is pressed against the stop port 1; a nut coats the water nozzle; a radial stop port 3 is formed in the upper end of a thread hole of the nut; the nut is in threaded connection with the stop port 1; the stop port 3 is pressed on the stop port 1; and a sealing ring 2 is embedded between the upper end surface of the stop port 1 and the lower end surface of the stop port 2.
Description
Technical field
The present invention relates to high-pressure water tank device, be specifically related to the housing of water tank and the linkage structure of water nozzle.
Background technique
General housing and water nozzle are threaded connection, and be wound around in the outside thread circumference of water nozzle the sealing that raw meal belt guarantees connection, but when being vibrated, the part be threaded easily loosens, raw meal belt sealability reduces, and causes leak of liquid.
Summary of the invention
For the problems referred to above, the housing of water tank and the linkage structure of water nozzle have been encircleed in the present invention, and it can have avoids the connection because vibrating housing and the water nozzle caused to loosen, and guarantees the sealing that the housing of water tank is connected with water nozzle to prevent leak of liquid.
Its technological scheme is such, the 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 step surface of described step hole are fitted, 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 radial seam two, 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 radial seam three, described nut is threaded with described seam one, and described seam three press-fits on described seam one, seal ring two is embedded with between the upper-end surface of described seam one and the lower end surface of described seam two.
It is further characterized in that:
The circumference of described seam two is arranged with seal ring three, fits with the lower end surface of described seam three, the upper-end surface of described seam one respectively in the upper and lower end face of described seal ring three.
The bottom of described water nozzle is frustoconical, and described step hole is provided with the locating face of taper.
After adopting structure of the present invention, water nozzle and housing are threaded, and the seam two of water nozzle is resisted against on the seam one of housing, and passes through nut check, the position that can effectively prevent the water nozzle because vibration causes and housing to be threaded loosens, and guarantees the sealing that the housing of water tank is connected with water nozzle; Seal ring one is embedded with between the lower end surface of water nozzle and step surface, seal ring two is embedded with between the upper-end surface of seam one and the lower end surface of seam two, the circumference of seam two is 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, guarantee further the sealing that the housing of water tank is connected with water nozzle to prevent leak of liquid.
