Abstract
The utility model discloses a flat three-claw type filter wrench, and relates to a manual tool for disassembling and assembling a filter. The flat three-claw type filter wrench consists of a panel, a bottom plate, a central gear and a gear with feet which are assembled, wherein the central gear is meshed with gear teeth of the gear with feet; the two ends of a rotating shaft of the central gear are respectively sheathed in rotating shaft holes at the centers of the panel and the bottom plate; and the center positions of arcs of three corners of the panel and the bottom plate are respectively provided with round holes. The flat three-claw type filter wrench is characterized in that the rotating shaft of the center gear, sheathed at one side of the panel, is provided with a section of extending body; the outer part of a central square hole of the extending body is made into a hexagon nut shape; the panel, the gear with the feet and the bottom plate are assembled by adopting rivets, the rivets penetrate through the round holes of the panel, the gear with the feet and the bottom plate to clamp the gear with the feet and the central gear between the panel and the bottom plate.
Description
Technical field
The utility model relates to the hand-operated tools that the dismounting cleaner is used.
Background technology
Existing a kind of flat three-jaw cleaner spanner that is used for the dismounting cleaner, this spanner is assemblied by panel, base plate, central gear, band pin gear, extension bar, screw, packing ring.Panel is identical with base plate profile specification, the basic triangularity of its profile, and three limits are arcs of recesses, and the bight is in the arc-shaped, and the arcs of recesses curve of the circular arc in its bight and adjacent side crosses along slipping over; The center of panel and base plate is shaped on shaft hole respectively, and panel and base plate are shaped on circular hole respectively at the circular arc home position in three bights.The rotating shaft of ining succession of the center of central gear, the axle center of rotating shaft is shaped on square hole, and the rotating shaft two ends of central gear are enclosed within respectively in the shaft hole at panel and base plate center.The fluted disc of band pin gear and pin handle are that one constitutes, and the fluted disc center of band pin gear is shaped on circular hole, and the pin handle outer end is bent into rectangular-shaped.Three circular hole rigging screw on panel and the base plate and packing ring, screw pass the circular hole of panel, band pin gear and base plate, will be withs pin gear and central gear to be installed between panel and the base plate, and make central gear and the gear teeth meshing of being with the pin gear.When flat three-jaw cleaner spanner uses, need in the square hole of central gear rotating shaft, insert extension bar with square tenon, by extension bar center of rotation gear, the central gear rotation promptly drives three band pin gears and rotates simultaneously, the rotating band of band pin gear three pin handle adjustable ranges, when the tight turn cleaner of three pin spindle clamps, be rotated further the dismounting that extension bar can be realized cleaner.Because the rotating shaft of flat three-jaw cleaner spanner and extension bar adopt the split combination, increased part and be equipped with and material consumption, also increased operational sequence.In addition, three screws that are assemblied in panel and base plate are loosening easily, influence central gear and normal cooperation of being with the pin gear.
The utility model content
The utility model technical issues that need to address provide a kind of flat three-pawl type cleaner spanner reliable, easy and simple to handle that uses.
The technical solution of the utility model is assemblied by panel, base plate, central gear, band pin gear, central gear and the gear teeth meshing of being with the pin gear, the rotating shaft two ends of central gear are enclosed within respectively in the shaft hole at panel and base plate center, panel and base plate are shaped on circular hole respectively at the circular arc home position in three bights, it is characterized in that the rotating shaft that central gear is enclosed within panel one side has one section ennation, the hex nut shape is made in the outside of this ennation center square hole; Panel, band pin gear and base plate adopt the rivet assembling, and rivet passes the circular hole of panel, band pin gear and base plate and will be with pin gear and central gear to be installed between panel and the base plate.
The utility model has the advantages that having reduced part is equipped with and material consumption, flexible and convenient operation not only can adopt extension bar to pull and also can adopt common monkey spanner to pull.It is loosening that panel and base plate adopt the rivet assembling to be difficult for, and central gear is normally cooperated with band pin gear, durable in use.
Description of drawings
What accompanying drawing was represented is the structural representation of flat three-pawl type cleaner spanner.
The specific embodiment
The utility model (seeing accompanying drawing) adopts panel 1, base plate 5, central gear 2, the band pin gear 4 of existing flat three-jaw cleaner spanner, central gear 2 and the gear teeth meshing of being with pin gear 4, panel 1 is shaped on circular hole 6 respectively with the circular arc home position of base plate 5 in three bights, the rotating shaft two ends of central gear 2 are enclosed within respectively in the shaft hole at panel and base plate center, the rotating shaft that central gear 2 is enclosed within panel one side has one section ennation, and the hex nut shape is made in the outside of this ennation center square hole; Panel, base plate, band pin gear adopt the rivet assembling, and rivet 3 passes the circular hole of panel, band pin gear and base plate and will be with pin gear and central gear to be installed between panel and the base plate.
