Embodiment 1

[0050] Figure 1 to Figure 5 As shown, a rack-and-pinion transmission device provided in this embodiment includes: a rack 1, on which a chute 11 is arranged; 21, and the second support part 22 which is arranged at an angle with the first support part 21; several balls 3 are movably arranged on the first support part 21, and at least partially contact with a groove wall of the chute 11; the gear 4 is set The second supporting part 22 meshes with the rack 1 , and the gear 4 is driven by an external force to move the movable bracket 2 to reciprocate on the rack 1 . In this embodiment, the gear 4 in this application reciprocates on the rack 1, and the maximum stroke of the gear 4 is the length of the rack 1, which solves the problem that the gear drives the rack in the prior art to achieve the same rack length. The stroke also needs to reserve at least one rack length of movement space, resulting in the problem that the product structure is not compact. Similarly, the gear 4 move...

Embodiment 2

[0064] Such as Figure 6 As shown, it is a panel translational structure provided in this embodiment, including: the rack and pinion transmission device in Embodiment 1, the rack 1 of the rack and pinion transmission device is fixedly arranged by itself, and the rack 1 in this embodiment is fixed On the external frame, and the connecting plate 7, connected on the movable support 2, a panel is arranged on it, and the use of the above-mentioned rack and pinion transmission device reduces the driving force required for the panel to move, and at the same time makes the panel move Smoother and less noise.

[0065] This embodiment also includes: a slide rail assembly 8, arranged side by side with the rack 1, which has a slide rail 81 and a slide block 82 movably arranged on the slide rail 81, one end of the connecting plate 7 is connected to the slide rail The blocks 82 are connected, and the setting of the slide rail assembly 8 can make the panel move more smoothly. The connecting...

Embodiment 3

[0067] This embodiment provides a gas cooker, including the rack and pinion transmission device in Embodiment 1, or the panel translation structure in Embodiment 2, and has all the technical advantages thereof, which will not be repeated here.

Abstract

The invention provides a gear rack transmission device, a panel translation device and a gas stove; the gear rack transmission device comprises a rack, a movable support, a plurality of balls and a gear, wherein a sliding groove is formed in the rack; the movable support has a first support part which partially extends into the sliding groove and a second support part which is arranged at an anglewith the first support part; the balls are movably arranged on the first support part, and at least part of the balls are in contact with the groove wall of the first sliding groove; the gear is arranged on the second support part and is meshed with the rack, and the gear is driven by an external force to drive the movable support to do reciprocating motion on the rack. The gear rack transmissiondevice solves the problems that a gear and rack transmission device in the prior art is not compact in structure and high in noise.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a rack and pinion transmission device, a panel translation structure, and a gas stove. Background technique [0002] Gear transmission is one of the main forms of mechanical transmission. Because of its advantages such as large speed ratio range, wide power range, compact and reliable structure, etc., it has been widely used in various mechanical equipment and instruments, and has become the most popular in existing mechanical products. A transmission with the largest proportion has broad application prospects. [0003] The existing rack-and-pinion linkage mechanism usually includes the following structures: a gear, a rack and a track groove, the gear and the rack are fitted and meshed, the rack is slidably installed in the track groove, and the gear is fixedly connected to the motor shaft. The rotation of the motor drives the gear to rotate, and the rack meshed wit...
