Abstract

The utility model relates to a pedal type water valve for a kitchen sink. The pedal type water valve comprises a pedal, a base plate, a water valve body, a transmission rack, a water valve seat, a water valve gear and a rack protecting sleeve. One end of the transmission rack is welded onto the pedal, and the other end of the transmission rack penetrates a rack hole arranged on the base plate. The rack protecting cover is mounted on the rack hole. The water valve seat is disposed on the base plate. The water valve body is mounted on the water valve seat. A spool of the water valve body is connected with the water valve gear which is meshed with the transmission rack. One end of the pedal is hinged to the base plate. The pedal is connected with the base plate through a resilient spring hinge pin. By a resilient spring system designed in a rotary shaft, pedal stability is increased, internal space of the pedal is saved, and appearance attractiveness of the pedal is achieved.

A kind of kitchen basin pedal-type water valve

Technical field

The utility model relates to a kind of kitchen basin pedal-type water valve.

Background technique

A lot of pedal water valves are arranged on the market, and some is directly by a simple spring return, and some is by the spring return in the spool of water valve, and such structure is not that stable missionary society is poor durability, the structure space layout that has even influence this pedal.

The model utility content

Problem to be solved in the utility model is: make the return spring mechanism performance of pedal stable, rational in infrastructure, reduce integrally-built influence.

In order to address the above problem, the technical solution of the utility model is: a kind of kitchen basin pedal-type water valve comprises that pedal, base plate, water valve, driving rack, water valve seat, water valve gear and tooth bar protecting jacket constitute; Described driving rack one end is welded on the pedal, and the other end passes the rack bore that is located on the base plate; In rack bore the tooth bar safety cover is housed; Base plate is provided with a water valve seat, and water valve is installed on the water valve seat, the spool of the water valve water valve gear of ining succession, water valve gear and driving rack engagement; Pedal one end is articulated in and base plate, and the two connects by joint pin; The side of being, the stage casing mandrel of hinge pin, two ends are cylinder axis, the cross section of the side of being inscribed within, cylinder axis cross section mandrel; Side's mandrel is corresponding with the square pin axis hole on the base plate, both Spielpassung; The position of the circular pin axis hole on the cylinder axis at two ends and the pedal is corresponding; Port section at cylinder axis has spring groove, and this cylinder axis is provided with two linings, and this lining is placed on the cylinder axis, both Spielpassung; This lining can be inserted in the circular pin axis hole simultaneously, in, the two is Spielpassung; Spring housing is on cylinder axis, and the spring bottom is a spring lateral pin that crosses the center of circle, and top is that outer spring detent is pointed in a reverse center of circle; The spring lateral pin of spring bottom inserts in the spring groove, and the spring detent on the spring inserts in the interior spring fixed hole of circular pin axis hole hole wall.

Its beneficial effect is: spring return system designs in rotating shaft, improves the stability of pedal, and serviceability is saved the pedal inner space, beautifies outward appearance.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Referring to accompanying drawing 1, a kind of kitchen basin pedal-type water valve comprises pedal 1, base plate 2, water valve 3, driving rack 11, water valve seat 21, water valve gear 31 and tooth bar protecting jacket 23; Described driving rack 11 1 ends are welded on the pedal 1, and the other end passes the rack bore 22 that is located on the base plate 2; In rack bore 22 tooth bar safety cover 23 is housed; Base plate 2 is provided with a water valve seat 21, and water valve 3 is installed on the water valve seat 21, the spool of the water valve 3 water valve gear 31 of ining succession, water valve gear 31 and driving rack 11 engagements; Referring to Fig. 2,3,4,5,6, pedal 1 one ends are articulated in and base plate 3, and the two connects by joint pin 4; The side of being, the stage casing mandrel 41 of hinge pin 4, two ends are cylinder axis 45, the cross section of the side of being inscribed within, cylinder axis 45 cross section mandrel 41; Side's mandrel 41 is corresponding with the square pin axis hole 24 on the base plate 2, both Spielpassung; The position of the circular pin axis hole 12 on the cylinder axis 45 at two ends and the pedal 1 is corresponding; Port section at cylinder axis 45 has spring groove 43, and this cylinder axis 45 is provided with two linings 42, and this lining 42 is placed on the cylinder axis 45, both Spielpassung; This lining 42 can be inserted in circular pin axis hole 12 simultaneously, in, the two is Spielpassung; Spring 44 is enclosed within on the cylindrical body 45, and spring 44 bottoms are spring lateral pins 441 that cross the center of circle, and top is that outer spring detent 442 is pointed in a reverse center of circle; The spring lateral pin 441 of bottom inserts in the spring groove 43; Referring to Fig. 7,8, the spring detent 442 on the spring 44 inserts in the interior spring fixed hole 121 of circular pin axis hole 12 hole walls.

In the use, because spring 44 is fixed on the hinge pin 4 by spring lateral pin 441, and square mandrel 41 parts of hinge pin 4 are in the square pin axis hole 24 that is inserted on the base plate 2, so it is moving that hinge pin 4 maintains static, when treadling, the spring lateral pin 441 of spring 44 1 ends is to be inserted in the spring fixed hole 122 of pedal 1, spring 44 is along with 1 deformation that treadles, after removing power, spring 4 recovers deformation, drives the pedal return.
