Description

A kind of band spiral fluted high-pressure pump lid

Technical field

This utility model is related to a kind of water pump accessory and in particular to a kind of high-pressure pump lid.

Background technology

Existing high-pressure pump lid, generally by seal in threaded connection place plus glue realization, but this scheme Defect is, when the high-pressure hydraulic pump that needs repairing is internal, to be difficult to take off the high-pressure pump lid having added glue, and in high pressure Water pump inside water pressure and water speed are all very big, and washing away of water under high pressure can be so that high-pressure pump lid rotates and pump housing dropout.

Content of the invention

Utility model purpose：The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of band spiral shell The high-pressure pump lid of spin slot.

Technical scheme：This utility model provides a kind of band spiral fluted high-pressure pump lid, including lid, helicla flute, lock Tight bolt, sleeve, loop bar, ripping bar and steel pawl, described helicla flute is opened under lid by the lid center rotation of lid outer circumference Surface, the described spiral fluted line of rabbet joint is Archimedes spiral, and the groove depth of described helicla flute outer circumference helicla flute center gradually subtracts Little, helicla flute periphery groove depth is 0.5～1.5 times of helicla flute center groove depth, and described covered body wall inner surface is provided with and pump housing phase The screw thread of adaptation, described lid is contrary with spiral fluted direction of rotation with respect to the direction of rotation of the pump housing, described covered body wall footpath It is arranged with two clamping screws, the through hole interference fit of described clamping screw and covered body wall to direction, described lid is radially Direction is also arranged with two ripping bars, is all articulated with lid upper surface neighboring in the middle part of described ripping bar, and described ripping bar upper end is divided Not hinged with loop bar one end, the described loop bar other end is all threadedly connected to sleeve inner, and described ripping bar bottom is provided with steel pawl.

Preferably, described steel pawl outer surface is provided with rubber coating.

Preferably, described ripping bar is flexible ripping bar.

Preferably, described helicla flute center groove depth is not less than 3mm.

Preferably, described lid upper surface radial direction is symmetrical arranged two handles, and described handle is with vertical direction as axle Rotate.

Beneficial effect：A kind of band spiral fluted high-pressure pump lid of the present utility model, Archimedes's spiral shell of lid lower surface Linear helicla flute, the resistance conversion in helicla flute of the water of water pump internal high pressure high speed is changed into the power advancing, and disperses Act on the hydraulic pressure on lid, the groove depth due to helicla flute outer circumference helicla flute center is gradually reduced, and water is in helicla flute Resistance can also be converted into the twisting resistance to lid, locks bolt and the locking machine of sleeve, loop bar, ripping bar and steel pawl composition Structure, prevents lid from threading off in the lower absent-mindedness of washing away for a long time of current.

Specific embodiment

For further appreciating that content of the present utility model, in conjunction with accompanying drawing, this utility model is described in detail.

As shown in Figure 1, Figure 2 and Figure 3, a kind of band spiral fluted high-pressure pump lid, including lid 1, helicla flute 2, locking screw Bolt 3, sleeve 4, loop bar 5, ripping bar 6 and steel pawl 7, helicla flute 2 is opened under lid 1 by the outer circumference lid 1 center rotation of lid 1 Surface, the line of rabbet joint of helicla flute 2 is Archimedes spiral, and the groove depth of outer circumference helicla flute 2 center of helicla flute 2 is gradually reduced, water Resistance conversion in helicla flute 2 for the water of pump internal high pressure high speed is changed into the power advancing, and has disperseed to act on lid 1 Hydraulic pressure, the groove depth due to outer circumference helicla flute 2 center of helicla flute 2 is gradually reduced, and the resistance in helicla flute 2 can also be converted into Twisting resistance to lid 1, helicla flute 2 periphery groove depth is 0.5～1.5 times of helicla flute 2 center groove depth, helicla flute 2 center groove Deeply it is not less than 3mm, prevent lid 1 thinnest part insufficient strength, lid 1 side wall inner surfaces are provided with the screw thread being adapted with the pump housing, lid Body 1 is contrary with the direction of rotation of helicla flute 2 with respect to the direction of rotation of the pump housing, and lid 1 side wall radial direction is arranged with two Clamping screw 3, the through hole interference fit of clamping screw 3 and lid 1 side wall, lid 1 radial direction is also arranged with two ripping bars 6, ripping bar 6 is flexible ripping bar, suitably adjusts the length of ripping bar 6 to coordinate the different pump housings, is all articulated with lid 1 in the middle part of ripping bar 6 Periphery edge, ripping bar 6 upper end is hinged with loop bar 5 one end respectively, and loop bar 5 other end is all threadedly connected to inside sleeve 4, sled Bar 6 bottom is provided with steel pawl 7, and steel pawl 7 outer surface is provided with rubber coating, prevents card bad pump housing outer wall, make while increasing friction force Used time, torsion sleeve 4 makes loop bar 5 move away from lid 1 central horizontal, promotes ripping bar 6 to do lever motion so that under ripping bar 6 The steel pawl 7 at end blocks the threaded pump housing outer wall of lid 1, and lid 1 upper surface radial direction is symmetrical arranged two handles 8, handss Handle 8 is rotated with vertical direction for axle, exerts a force when conveniently uncapping.
