[0003] In existing technology, when an LED projection clock projects, the laser emitting module is adjusted. The adjustment is usually achieved by using damping to stabilize the rotation angle. However, the existing damping force is not stable enough, and over time, the rotation damping point may become disengaged, making it impossible to stabilize the angle of the laser emitting module.

[0014] The beneficial effects of this utility model are as follows:
[0015] 1. The adjustable-angle LED projection clock of this utility model uses a positioning component to perform angle positioning operation on the laser emitting module, which is stable and fixed and will not cause any detachment. At the same time, the base is attracted by an adsorption component, which also allows the base to be placed stably on the table, reducing the impact of the external environment on the shell.
[0016] 2. The adjustable-angle LED projection clock of this utility model allows for adjustment of the laser emitting module angle by rotating the first threaded rod in the opposite direction, causing the cylinder to slowly disengage from the positioning groove while the arc surface remains within it. Simultaneously, the L-shaped plate provides a contact and positioning operation. The laser emitting module can then be manually adjusted, as the arc surface does not obstruct the rotation of the positioning groove and provides some damping force, facilitating adjustment. After angle adjustment, the first threaded rod is rotated again, causing the cylinder to fully insert into the positioning groove, completing the positioning operation. This method is simple, convenient, and provides a fixed positioning, preventing instability.

[0039] like Figures 1 to 8 As shown, the adjustable-angle LED projection clock of this utility model includes a housing 1; a base 11 is fixedly connected to the bottom end of the housing 1; a first groove 12 is formed on the housing 1, and both sides of the first groove 12 are open; a laser emitting module 13 is provided in the first groove 12; a first rotating shaft 14 is fixedly connected to both side walls of the laser emitting module 13, and the first rotating shaft 14 is rotatably connected to the side walls of the first groove 12; the laser emitting module 13 is fixed by a positioning component; the bottom end of the base 11 is adsorbed by an adsorption component; in the prior art, LED projection clocks... During projection, the laser emitting module 13 is adjusted. This adjustment is usually achieved by using damping to stabilize the rotation angle. However, the existing damping force is not stable enough, and over time, it can cause the rotation damping to disengage, making it impossible to stabilize the laser emitting module 13 at the angle. Therefore, this invention uses a positioning component to position the laser emitting module 13 at the angle during operation, ensuring a stable and secure fixation without disengagement. At the same time, the base 11 is attached using an adsorption component, allowing it to be placed stably on the table and reducing the impact of the external environment on the housing 1.
[0040] The positioning component includes a positioning circular groove 2; arc-shaped blocks 29 are fixedly connected to both side walls of the laser emitting module 13; positioning circular grooves 2 are opened on both the side walls of the arc-shaped blocks 29 and the laser emitting module 13, and a set of positioning circular grooves 2 are distributed in a circle; a threaded through groove 21 is opened on the side wall of the first groove 12, and a first threaded rod 22 is threadedly connected in the threaded through groove 21.
[0041] The first threaded rod 22 has a first circular groove 23 at its end; a cylinder 24 is fixed to the bottom of the first circular groove 23 by a spring; and an arc surface 25 is formed at the end of the cylinder 24.
[0042] An annular groove 26 is provided on the outer side wall of the end of the first threaded rod 22; an inverted L-shaped plate 27 is fixedly connected to the side wall of the housing 1, and the end of the inverted L-shaped plate 27 is located in the annular groove 26.
[0043] During operation, when the angle of the laser emitting module 13 needs to be adjusted, the first threaded rod 22 can be rotated in the opposite direction, causing the cylinder 24 to slowly disengage from the positioning groove 2, while the arc surface 25 remains within the positioning groove 2. Simultaneously, the L-shaped plate 27 performs a fitting and positioning operation. At this point, the laser emitting module 13 can be manually adjusted. Because the arc surface 25 does not obstruct the rotation of the positioning groove 2 and also has a certain damping force, adjustment is convenient. After the angle is adjusted, the first threaded rod 22 is rotated again, causing the cylinder 24 to fully insert into the positioning groove 2, completing the positioning operation. This is simple and convenient, and the positioning is fixed, preventing instability.
[0044] A set of anti-slip grooves 28 are provided on the outer wall of the arc-shaped block 29; during operation, the anti-slip grooves 28 facilitate the swinging operation of the laser emitting module 13.
[0045] The adsorption component includes a suction cup 3; a set of suction cups 3 are fixedly connected to the bottom end of the base 11; a first cavity 31 is opened inside the base 11; a set of connecting holes 32 are opened at the bottom end of the first cavity 31, and the connecting holes 32 connect the first cavity 31 and the suction cups 3.
[0046] The housing 1 has a second cavity 33; a sealing plate 35 is slidably connected to the second cavity 33; a set of air outlets 34 are provided on the side wall of the second cavity 33; the second cavity 33 is connected to the first cavity 31 through a first hose 36;
[0047] A second threaded rod 37 is rotatably connected to the side wall of the sealing plate 35, and the second threaded rod 37 extends out of the housing 1 and is threadedly connected to the through-hole; positioning plates 38 are fixedly connected to the upper and lower side walls of the second cavity 33.
[0048] During operation, when the suction cup 3 needs to be stably placed on the table, place it on the table, then rotate the second threaded rod 37 to move the sealing plate 35, and suck air into the first cavity 31 through the first hose 36. Then, perform a vacuum operation on the suction cup 3 through the connecting hole 32 to complete the adsorption and fixation of the chassis. When it is necessary to change the placement position of the housing 1 later, push the sealing plate 35 to inflate the suction cup 3, release the vacuum, and complete the disassembly operation.
[0049] The LED projection clock mainly consists of: a clock module, a laser emitting module, a processing module, an infrared sensing module, a power supply module, an luminous dial, a central processing unit, a clock circuit, an LED constant current drive circuit, a microphone and voice control circuit, a speaker and sound effect circuit, buttons, a stop button, a power supply circuit, a USB power and data interface, a power switch, and an outer casing, etc. These are existing technologies and will not be described in detail. At the same time, the design of this utility model does not hinder the operation of the internal circuit components of the projection clock.
[0050] Working principle: The laser emitting module 13 is positioned at an angle using a positioning component, ensuring stable locking and preventing disengagement. Simultaneously, the base 11 is attracted by an adsorption component, allowing it to rest stably on the table and reducing the impact of the external environment on the housing 1. When adjusting the angle of the laser emitting module 13, the first threaded rod 22 is rotated in the opposite direction, causing the cylinder 24 to slowly disengage from the positioning groove 2, while the arc surface 25 remains within the groove. Simultaneously, the inverted L-shaped plate 27 provides contact and positioning. The laser emitting module 13 can then be manually adjusted, as the arc surface 25 does not obstruct the rotation of the positioning groove 2 and provides some resistance. The suction cup 3 is easy to adjust. After adjusting the angle, rotate the first threaded rod 22 again to make the cylinder 24 fully insert into the positioning groove 2, thus completing the positioning operation. It is simple and convenient, and the positioning is fixed, so there will be no instability. When it needs to be placed stably on the table, place the suction cup 3 on the table, and then rotate the second threaded rod 37 to move the sealing plate 35. The first cavity 31 is then sucked through the first hose 36, and then the suction cup 3 is vacuumed through the connecting hole 32, thus completing the suction fixation of the chassis. When it is necessary to change the placement position of the housing 1 later, push the sealing plate 35 to inflate the suction cup 3, release the vacuum, and then complete the disassembly operation.
