[0001] The present invention belongs to the technical field of video projectors, and specifically relates to an adjustable video projector. Background Art

[0002] A projector, also known as a projection machine, is a device that can project images or videos onto a screen. It can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, DLP, 3LCD, etc. The invention patent with the publication number CN107270058A discloses an adjustable audio and video projector, including a roof plate and a projector. An adjusting device for adjusting the projector is provided between the projector and the roof plate. The adjusting device includes a first cross bar and a second cross bar. The upper surface of the first cross bar is connected to the roof plate through a connecting slider, and the second cross bar is connected to the projector through a connecting block. Two vertical adjusting rods are symmetrically arranged on both sides between the first cross bar and the second cross bar. The rotating gear on the lower surface of the first cross bar is engaged with the side surface of the vertical adjusting rod, and the rotating shaft of the rotating gear is connected to the rotating shaft of the driving motor on the lower surface of the center of the first cross bar through a transmission belt. This patent uses the driving motor as the adjustment power to achieve intelligent ground operation, improve the simplicity of adjustment, reduce the adjustment difficulty, and at the same time adopt rotational angle adjustment to adapt to audio and videos at different heights to achieve the best projection angle and improve the projection quality. However, there are some problems with current video projectors: 1. During use, the placement surface is not absolutely horizontal, and when the placement surface is inclined, it is easy to cause the projection to be inclined, affecting the projection quality; 2. During the use of the projector, to ensure the stable placement of the projector, a relatively large base is required, which affects the storage and portability of the projector. Therefore, it is necessary to design an adjustable video projector. Summary of the Invention

[0003] The purpose of the present invention is to provide an adjustable video projector to solve the above problems, which solves the problems mentioned in the above background art.

[0004] To solve the above problems, the present invention provides a technical solution for an adjustable video projector:

[0006] Preferably, the angle adjusting mechanism includes a guide rod, a support plate, a rubber block, a fixed cover, an internally threaded tube, a rotating cover, a threaded column, an adjusting plate, and a first spring. A guide rod is fixedly connected inside the regulating base, a support plate is slidably connected to the outer side of the guide rod, a rubber block is fixedly connected to the outer side of the support plate, a fixed cover is fixedly connected to the outer side of the regulating base, an internally threaded tube is installed inside the fixed cover through a bearing, a rotating cover is fixedly connected to the outer side of the internally threaded tube, the rotating cover contacts the fixed cover, the internally threaded tube is rotatably connected to the regulating base, a threaded column is connected inside the internally threaded tube by means of a thread, one end of the threaded column is fixedly connected to an adjusting plate, a first spring is arranged on the outer side of the guide rod. By driving the internally threaded tube to rotate through the rotating cover, the internally threaded tube can drive the adjusting plate to move through the thread fit with the threaded column during rotation. During the movement of the adjusting plate, the first spring can be compressed. After the first spring is compressed, it deforms and the elastic force increases. The elastic force can be transmitted to the rubber block through the support plate and increase the friction between the rubber block and the spherical seat, thus completing the limitation of the projection angle of the projector.

[0007] Preferably, the support plate is slidably connected to the regulating base, the rubber block is slidably connected to the regulating base, and the rubber block contacts the spherical seat. The rubber block can increase the resistance of the spherical seat to rotate.

[0008] Preferably, the adjusting plate is slidably connected to the guide rod, one end of the first spring is fixedly connected to the support plate, and the other end of the first spring is fixedly connected to the adjusting plate. The first spring can support the support plate through the elastic force.

[0009] Preferably, the height adjustment mechanism includes a square groove, a square plate, a screw and a threaded ring. The interior of the rotating tube is fixedly connected to the threaded ring. The interior of the threaded ring is connected to the screw through a thread. One end of the screw is fixedly connected to the ball seat. A square groove is provided inside the adjustment tube. The threaded ring is driven to rotate by the rotating tube. During the rotation, the threaded ring can drive the ball seat at one end of the screw to move by cooperating with the thread between the threaded ring and the screw. During the movement of the ball seat, the height of the projector can be adjusted through the adjustment seat. When the image height is moderate, the rotating tube can be stopped.

[0010] Preferably, the other end of the screw rod is fixedly connected to a square plate, and the square plate is slidably connected to the square groove, and the square groove can guide the movement of the square plate.

The support leg is flipped, and the support leg drives the articulated frame to flip. During the flipping process, the articulated frame can push the positioning seat to move through the positioning slot and compress the spring second. When the positioning seat is out of the current positioning slot, the articulated frame and the support leg can be flipped to the horizontal position. When the articulated frame is horizontal, the spring second is reset. The spring second can drive the positioning seat to slide into the adjusted positioning slot through elastic force, so as to increase the supporting area of ​​the base. When it needs to be carried, it only needs to flip the support leg to the vertical position.

[0012] Preferably, one end of the second spring is fixedly connected to the base, and the other end of the second spring is fixedly connected to the positioning seat. The second spring can drive the positioning seat to automatically reset through elastic force.

In specific use, compared with the traditional adjustable video projector, the adjustable video projector has the following two beneficial effects:

[0014] Firstly, by adding structures such as an adjustment seat, a ball seat and a rubber block to the projector, the degree of freedom of adjustment of the projector can be increased through the movable connection between the hinged ball on the ball seat and the adjustment seat, so that the angle of the projector can be more easily adjusted. After adjustment, the angle of the projector can be limited by the rubber block.

[0015] Secondly, structures such as a hinge frame, support legs, and positioning seats are added to the base. During use, the support legs can be unfolded to increase the support area and make the device more stable when placed. When it needs to be carried, the support legs can be flipped vertically to reduce the overall volume of the device, making it more convenient for storage and carrying.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1-6 shown, the following technical solutions are adopted in this specific embodiment:

[0025] Example:

[0026] An adjustable video projector, comprising a projector 1, a regulating base 2 is fixedly connected to the lower end of the projector 1, a spherical seat 3 is movably connected inside the regulating base 2, a rotating tube 4 is in contact with the lower end of the spherical seat 3, an adjusting tube 5 is installed on the outer side of the rotating tube 4 through a bearing, one end of the adjusting tube 5 is fixedly connected to a base 6, a key 10 is arranged on the projector 1, a limiting ring 11 is connected to the inside of the regulating base 2 through a thread, and the limiting ring 11 is in contact with the spherical seat 3.

By driving the internally threaded tube 75 to rotate through the rotating cover 76, the internally threaded tube 75 can drive the adjusting plate 78 to move through the thread fit with the threaded column 77 during rotation. The adjusting plate 78 can compress the first spring 79 during movement. After the first spring 79 is compressed, its shape changes and the elastic force increases. The elastic force can be transmitted to the rubber block 73 through the support plate 72, and the friction force between the rubber block 73 and the spherical seat 3 is increased, thus completing the limitation of the projection angle of the projector 1. The support plate 72 is slidably connected to the regulating base 2, the rubber block 73 is slidably connected to the regulating base 2, the rubber block 73 is in contact with the spherical seat 3, and the rubber block 73 can increase the resistance of the spherical seat 3 to rotate.

When the hinge frame 91 is horizontal, the second spring 96 resets. The second spring 96 can drive the positioning seat 94 to slide into the adjusted positioning groove 93 through the elastic force, so as to increase the support area of the base 6. When carrying is needed, only the support leg 92 needs to be flipped vertically. One end of the second spring 96 is fixedly connected to the base 6, and the other end of the second spring 96 is fixedly connected to the positioning seat 94.

During the rotation of the threaded ring 84, it can drive the ball seat 3 at one end of the screw rod 83 to move through the threaded fit with the screw rod 83. During the movement of the ball seat 3, it can adjust the height of the projector 1 through the adjusting seat 2. When the image height is appropriate, stop rotating the tube 4;

[0032] Then deflect the projector 1. During the deflection process of the projector 1, the projection angle of the projector 1 can be adjusted through the movable connection between the ball seat 3 and the adjusting seat 2. After the adjustment is completed, rotate the cover 76 to drive the internal threaded tube 75 to rotate. During the rotation of the internal threaded tube 75, it can drive the adjusting plate 78 to move through the threaded fit with the threaded column 77. During the movement of the adjusting plate 78, it can compress the first spring 79. After the first spring 79 is compressed, its deformation causes the elastic force to increase. The elastic force can be transmitted to the rubber block 73 through the support plate 72 and increase the friction between the rubber block 73 and the ball seat 3, thereby completing the limitation of the projection angle of the projector 1.
