Description

Rotary projector

Technical Field

The present invention relates to a rotary projector, and more particularly, to a rotary projector that can project a rotation pattern by a rotating device that drives a film in the rotary projector to rotate.

Background

Conventional projectors can project sharp patterns. A conventional projector has a housing, an illumination section, a film, and an imaging lens. The housing has a protruding opening formed through a front end of the housing. The illumination member is mounted in the housing with its side facing the projection opening. The adhesive film is mounted in the housing and arranged in front of the illuminating member. An imaging lens is mounted in the projection opening and is disposed in front of the film. When a conventional projector is used, light is emitted from the illumination unit, passes through the film and the imaging lens, and forms a clear pattern on the surface.

However, the pattern projected by conventional projectors is static. Conventional projectors lack a mechanism to drive the film into rotation. The static mode causes visual fatigue to the viewer and does not create a pleasant atmosphere in the party when needed. A conference projector that projects a static pattern cannot be used in a happy occasion or a party.

To overcome the above disadvantages, the present invention is intended to provide a rotary projector to avoid the above problems.

Disclosure of Invention

The invention mainly aims to provide a rotary projector, which solves the problem that the static pattern projected by the traditional projector cannot be used in happy occasions or parties.

The rotary projector has a housing and a projection device. The housing has a housing, a mounting bracket, a power supply component, and a waterproof cover. The mounting bracket is mounted in the housing. The power supply component is mounted in the housing. The waterproof cover is mounted on the housing.

The projection device is disposed in the housing and has a driver, a drive shaft, a drive gear, an illumination component, a gear assembly, a gear cover, and a film roll assembly. The driver is mounted on the mounting bracket and electrically connected to the power supply unit. The drive shaft extends and is rotated by the driver. The drive gear is mounted on the drive shaft. The lighting component is arranged on the mounting bracket and is electrically connected with the power supply component. A gear assembly is rotatably mounted on the mounting bracket and is in meshing engagement with the drive gear. The gear cover is installed on the installation support and fixes the gear assembly. The film reel assembly is mounted on the gear assembly and is disposed in front of the illumination member.

The rotary projector also has a support device. The supporting device is arranged at the bottom of the shell and is provided with a frame and a grounding rod. The frame is rotatably mounted at the bottom of the housing. The ground rod is rotatably installed at the lower end of the frame.

The driver drives the drive gear and the gear assembly to rotate. While rotating the film roll assembly. The power of the illumination component is projection light, and a rotating pattern is projected through the film reel assembly. The rotation mode is dynamic and suitable for happy occasions or parties. Therefore, the rotary projector is practical.

Referring to fig. 1, 5 and 8, a support device 30 is mounted at the bottom of the

housing

11A, 11B, 11C, having a frame 31 and a ground bar 32. The chassis 31 is rotatably mounted to the bottom of the

housings

11A, 11B, 11C. The ground rod 32 is rotatably mounted to the lower end of the frame 31.

When the first preferred embodiment of the rotary projector is used, referring to fig. 2 to 4, the electric wire transmits electricity to the power supply part 13A located in the housing 11A. The power supply part 13A may convert Alternating Current (AC) into Direct Current (DC) and supply the direct current to the driver 21A and the illumination part 24A of the projection device 20A. When the driver 21A is energized, the driver 21A drives the drive shaft 22A and the drive gear 23A to rotate. The rotary gear 251A of the gear assembly 25A is simultaneously driven in rotation by the drive gear 23A. The film 271A mounted on the rotary gear 251A also rotates. When illumination element 24A is energized, light is emitted from illumination element 241A. The light passes through the film 271A mounted on the rotary gear 251A. Since the rotary gear 251A and the film 271A are simultaneously rotated, an image on the film 271A is projected as a rotation pattern. The rotary mode is dynamic and interesting, and is suitable for happy occasions or parties.

When the second preferred embodiment of the rotary projector is used, referring to fig. 5 to 7, the driving device 21B is energized and drives the driving shaft 22B and the driving gear 23B. The connecting gear 252B and the rotating gear 251B of the gear assembly 25B are simultaneously driven to rotate by the drive gear 23B. The film 271B mounted on the rotary gear 251B also rotates. When the illumination element 241B of the illumination element 24B is energized, light is emitted from the illumination element 241B and passes through the rotating film 271B. Thus, the images on the three films 271B are projected in three rotation patterns.

When the third preferred embodiment of the rotary projector is used, referring to fig. 8 to 10, the driver 21C is energized to drive the drive shaft 22C and the drive gear 23C to rotate. The transmission gear 252C and the rotation gear 251C of the gear assembly 25C are simultaneously driven to rotate by the transmission gear 23C. The film 271C mounted on the 251C rotary gear also rotates. When the lighting element 24C is energized, light is emitted from the lighting element 241C and the backlight assembly 244C. The light passes through the film 271C mounted on the 251C rotating gear and through the 252C transmission gear. Thus, the images on the three films 271C and the image of the backlight assembly 244C are projected into three rotation patterns and one background pattern. Rotating projectors allow viewers to see three dynamic rotating modes and one static mode.

Referring to fig. 1, 5 and 8, the bottom end of the ground rod 32 is pointed and can be inserted directly into the ground. Referring to fig. 2, 5 and 8, the

housings

11A, 11B and 11C are provided with

waterproof covers

14A, 14B and 14C, and the rotary projector can be used outdoors. Further, referring to fig. 3, 6 and 9, the color of the light emitted from the illuminating

members

24A, 24B, 24C may be changed to a different color of the projected pattern.

Accordingly, the rotary projector projects the rotation pattern of the

driving devices

21A, 21B, 21C, and drives the

driving devices

23A, 23B, 23C and the

gear assemblies

25A, 25B, 25C to rotate. While rotating the

film reel assemblies

27A, 27B, 27C.

Illumination elements

24A, 24B, 24C are energized to project light through

film reel assemblies

27A, 27B, 27C in a rotating pattern. The rotation mode is dynamic and suitable for happy occasions or parties. Therefore, the rotary projector is practical.
