Abstract
The present invention relates to an adjustable support foot of dishwater, wherein the adjustable support foot comprises an adjusting seat (1), a driving gear (2), a driven gear (3) and an adjusting screw bolt (4). The driving gear (2) is installed in a driving gear installing hole (11) of adjusting seat (1). The driven gear (3) is installed in a driven gar installing hole (12) of adjusting seat (1). The driven gear (3) is engaged with the driving gear (2). The adjusting screw bolt (4) is matched with the driven gear (3) and traverses a locating hole (13) of adjusting seat (1), wherein the cross section of threaded part of adjusting screw bolt (4) is drum-shaped. The locating hole (13) has a drum shape or rectangular shape matched with the adjusting screw bolt (4). The adjusting screw bolt (4) in the adjustable support foot is clamped in the locating hole (13) and is limited by two side walls of locating hole (13) therefore the adjusting screw bolt can not be rotated. The smooth adjusting of height of dishwasher is ensured. Furthermore two sides of adjusting screw bolt (4) is stressed when the adjusting screw bolt (4) resists rotation. The stress distribution is uniform and the durability is prolonged.
Description
Technical field
The present invention relates to a kind of bracing or strutting arrangement of home appliance, especially a kind of adjustable support foot that is applied to dish-washing machine.
Background technology
China utility model patent CN00218235.1, CN200720123384.1 all disclose a kind of dish-washing machine arrangement for adjusting height that adopts bevel gears, mainly comprise driving gear, driven gear and adjusting screw(rod), driving gear, driven gear are intermeshing conical gear, driven gear is provided with internal thread, adjusting screw(rod) is threaded onto in the driven gear, when gear mechanism rotates, adjusting screw(rod) can not rotate thereupon, thereby driven gear can be moved along adjusting screw(rod) is upper and lower, realize that the height of dish-washing machine is regulated.But because driven gear screws mutually with adjusting screw(rod),, then can't regulate the height of dish-washing machine smoothly, and all unexposed driven gear that how to prevent of above-mentioned two parts of patent documents drives the technical problem that adjusting screw(rod) rotates if not employing measure solves its interaction relation.
Summary of the invention
In order to overcome above technical problem, the invention provides a kind of simple in structure durablely, effectively regulate the adjustable support foot of height.
A kind of adjustable support foot of dish-washing machine, comprise adjustment seat, driving gear, driven gear and adjusting screw(rod), driving gear is installed in the driving gear installing hole of adjustment seat, driven gear is installed in the driven gear installing hole of adjustment seat, driven gear and driving gear engagement, adjusting screw(rod) cooperates and passes the locating hole of adjustment seat with driven gear, wherein the threaded portion cross section of adjusting screw(rod) is cydariform, and locating hole is cydariform or the rectangle suitable with adjusting screw(rod).
The sidewall of described locating hole is provided with through hole.
Described adjusting screw(rod) is made up of inner metal layer and outer plastic layer, and the threaded portion of adjusting screw(rod) is arranged at outer plastic layer.
Described driven gear is provided with axially extending bore, and internal thread is set on the axially extending bore, and the threaded portion of adjusting screw(rod) passes axially extending bore and screw-internal thread fit.
Described driving gear, driven gear are bevel spur gear or helical gear.
Adjusting screw(rod) in the adjustable support foot of the present invention is cydariform, and adaptive with it cydariform or rectangle locating hole be set on adjustment seat, when driven gear rotates, adjusting screw(rod) is sandwiched in the locating hole, can't rotate by the restriction of locating hole two side, thereby realizes that driven gear drives adjustment seat and dish-washing machine integral body moves up and down along adjusting screw(rod), and locating hole clamping adjusting screw(rod) both sides, both sides were stressed when adjusting screw(rod) resisted commentaries on classics, and stressed being evenly distributed helps to improve its durability.

The specific embodiment
Shown in Fig. 1 to 4, the adjustable support foot of dish-washing machine of the present invention, comprise adjustment seat 1, driving gear 2, driven gear 3 and adjusting screw(rod) 4, driving gear 2 is installed in the driving gear installing hole 11 (hole wall only is shown in the accompanying drawing) of adjustment seat 1, driven gear 3 is installed in the driven gear installing hole 12 of adjustment seat 1, driven gear 3 and driving gear 2 engagements, driven gear 3 is provided with axially extending bore, internal thread is set on the axially extending bore, the threaded portion of adjusting screw(rod) 4 passes axially extending bore and screw-internal thread fit and passes the locating hole 13 of adjustment seat 1, the threaded portion cross section of adjusting screw(rod) 4 is cydariform, locating hole 13 is cydariform or the rectangle suitable with adjusting screw(rod) 4, adjusting screw(rod) 4 is sandwiched in the locating hole 13, when driven gear 3 rotates, adjusting screw(rod) 4 can't be rotated by the restriction of locating hole 13 two sides, thereby realizes the function that dish-washing machine integral body moves up and down along adjusting screw(rod) 4.In addition, the sidewall of locating hole 13 is provided with through hole 14, observes contraposition when both being convenient to assemble, and also helps to reduce the frictional force between adjusting screw(rod) 4 and the locating hole 13, is convenient to regulate.
As shown in Figure 3, the end of driving gear 2 is provided with adjustment hole 21, and screwdriver is injected adjustment hole 21, turns, and driving gear 2 drives driven gear 3 rotations immediately makes driven gear 3 move up and down along adjusting screw(rod) 4.Driving gear 2 also is provided with draw-in groove 22, and draw-in groove 22 cooperates with collar 5 and prevents that driving gear 2 is axially displaced.
As shown in Figure 5, adjusting screw(rod) 4 is made up of inner metal layer 41 and outer plastic layer 42, and the threaded portion of adjusting screw(rod) 4 is arranged at outer plastic layer 42.
Driving gear 2, driven gear 3 among the present invention are bevel spur gear or helical gear.
