Abstract
The invention provides a connecting structure of sliding-rail synchronous gears, aiming to solve the problem that synchronous gears cannot be guaranteed to rotate with a connecting shaft synchronously in an existing structure and guaranteeing smooth sliding of a drawer. The connecting structure comprises two parallel mounted rack sliding rails, two synchronous gears and a connecting shaft. The two synchronous gears are mounted on the two rack sliding rails respectively and are connected with the two rack sliding rails in a teeth-shaped meshing manner. The two synchronous gears are connected through the connecting shaft. The connecting structure is characterized in that one connecting shaft hole is reserved on each synchronous gear, teeth-shaped grooves are reserved on the periphery of the connecting shaft holes, positioning teeth matched with the teeth-shaped grooves of the connecting shaft holes are arranged on the outer circumference of the connecting shaft, and the positioning teeth of the connecting shaft holes can be mounted with the teeth-shaped grooves of the connecting shaft in a clearance manner directly.
Description
Technical field
The present invention relates to household electrical appliance rail structure field, especially relate to the rail structure field for large-capacity refrigerator, be specially the syndeton of slide rail synchronizing wheel.
Background technology
Generally because the horizontal cross spacing of large-capacity refrigerator is larger, in order to ensure that refrigerator drawer can pull reposefully, usually longitudinally pull direction is installed by synchronous sliding track mechanism in drawer lower horizontal transverse ends, synchronous sliding track mechanism comprises the synchronous tooth bar slide rail 1 of the longitudinally parallel installation in pull direction, two synchromesh gears 8 being installed on drawer are connected with a joggle with synchronous tooth bar slide rail 1 profile of tooth, see Fig. 1, between two synchromesh gears 8, connecting axle 9 is also installed, to guarantee that two ends gear 8 can rotate on respective tooth bar slide rail 1 in synchro-meshing, its shortcoming is: connecting axle 9 two ends are connected with two gears 8 respectively by axle sleeve 10, be connected and fixed by alignment pin 11 between connecting axle 9 and axle sleeve 10, because connecting axle is not be connected with direct geared, be subject to assemblage gap between connecting axle and axle sleeve to affect two ends gear and cannot ensure synchronous axial system, thus cause drawer to occur the stuck phenomenon of side when pull, impact is normal to be used.
Summary of the invention
For the problems referred to above, the invention provides the syndeton of slide rail synchronizing wheel, it can solve the problem that existing structure cannot ensure synchronizing wheel and connecting axle synchronous axial system, guarantees that drawer can steadily slippage.
Its technical scheme is such, it comprises the tooth bar slide rail of two parallel installations, two synchromesh gears and connecting axle, described two synchromesh gears are installed on described two tooth bar slide rails respectively, and be connected with a joggle with described two tooth bar slide rail profiles of tooth, connected by described connecting axle between described two synchromesh gears, it is characterized in that: described two synchromesh gears all have connecting shaft hole, the side face of described connecting shaft hole has serrate slot, the outer peripheral face of described connecting axle is provided with the positioning tooth matched with the serrate slot of described connecting shaft hole, between the positioning tooth of described connecting axle and the serrate slot of connecting shaft hole, direct gap is assembled.
It is further characterized in that: described connecting axle two ends have radial direction through hole near described synchromesh gear installation end, are fitted with alignment pin in described radial direction through hole.
Adopt structure of the present invention, its beneficial effect is: its connecting axle and two ends synchromesh gear are directly connected, and ensure that the synchronous axial system of two synchromesh gears and connecting axle, ensure that the reliable steadily slippage of drawer.

Detailed description of the invention
See Fig. 2, Fig. 3 and Fig. 4, the present invention includes the tooth bar slide rail 1 of two parallel installations, two synchromesh gears 2 and connecting axle 3, two synchromesh gears 2 are installed on two tooth bar slide rails 1 respectively, and be connected with a joggle with two tooth bar slide rail 1 profiles of tooth, connected by connecting axle 3 between two synchromesh gears 2, two synchromesh gears 2 all have connecting shaft hole 4, the side face of connecting shaft hole 4 has serrate slot 5, the outer peripheral face of connecting axle 3 is provided with the positioning tooth 6 matched with the serrate slot 5 of connecting shaft hole 4, between the positioning tooth 6 of connecting axle 3 and the serrate slot 5 of connecting shaft hole 4, direct gap is assembled.Connecting axle 3 two ends have radial direction through hole near synchromesh gear 2 installation end, are fitted with alignment pin 7 in radial direction through hole, and alignment pin 7 plays the effect preventing connecting axle axial float.
