Abstract
A projection device includes a housing, a rotating component, and a foot pad component. The housing has the first and second parts. The second part has a screw hole. The rotating component has an abutting part and a driving part. The abutting part passes through and abuts against the first part. The foot pad component has a foot pad part, a screw rod part, and a driven-to-move part. The screw rod part is connected between the foot pad part and the driven-to-move part and screwed to the second part through the screw hole. The driven-to-move part is in the housing and embedded in the driving part. The rotating component rotates relative to the first part, causing the foot pad component to be driven by the rotating component to rotate relative to the second part, thereby changing a height of the housing relative to the foot pad part.
Claims15
A projection device, comprising:
- a housing, having a first part and a second part disposed on opposite sides of the housing, wherein the second part has a screw hole;
- a rotating component, having an abutting part and a driving part connected to each other, wherein the abutting part is arranged to pass through and abut against the first part, and the driving part is located inside the housing, the abutting part has an actuating section and an abutting section, the abutting section is connected between the actuating section and the driving part, the actuating section is located outside the housing, the abutting section is located inside the housing, and a portion of the first part is sandwiched between the actuating section and the abutting section;
- and
- a foot pad component, having a foot pad part, a screw rod part, and a driven-to-move part, wherein the screw rod part is connected between the foot pad part and the driven-to-move part and is screwed to the second part through the screw hole, the driven-to-move part is located in the housing and is embedded in the driving part, and the foot pad part is located outside the housing;
- wherein the rotating component is configured to rotate relative to the first part, causing the foot pad component to be driven by the rotating component to rotate relative to the second part, thereby adjusting a distance of the housing relative to the foot pad part.

- and
- a limiting ring, sleeved on the driven-to-move part and abutting against the screw rod part, wherein in a radial direction of the screw rod part, a width of the limiting ring is greater than a width of the screw rod part;
- wherein the rotating component is configured to rotate relative to the first part, causing the foot pad component to be driven by the rotating component to rotate relative to the second part, thereby adjusting a distance of the housing relative to the foot pad part.
