Description

a projector

technical field

The utility model belongs to projection equipment, in particular to a projector.

Background technique

A projector, also known as a projector, 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 the corresponding video signal. Projectors are widely used in homes, offices, schools, and entertainment venues; as projector designs get smaller, many are portable. However, during the installation process of the projector, it is difficult to align the displayed image with the projection screen for different environments and places, especially when the table is uneven, or the projector is higher than the projection screen, the projection surface is often tilted, unable to The situation of aligning the projection screen seriously affects the projection effect.

Utility model content

The purpose of the utility model is to solve the above problems and provide a projector with simple structure and convenient adjustment of projection height and angle.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is: a projector, including a body, an annular groove opened on the bottom surface of the body, a slider slidably connected to the annular groove, and an adjustment screw pierced through the slider. The screw fits the slider thread.

Preferably, there is at least one sliding block and one adjusting screw.

Preferably, the depth of the annular groove is greater than the length of the adjusting screw.

Preferably, the body is provided with a projection lens.

The beneficial effects of the utility model are: the projector provided by the utility model is equipped with a slidable adjustment screw on the bottom surface of the projector body, and the height and angle of projection can be adjusted by sliding the adjustment screw and fine-tuning the length of the adjustment screw protruding from the bottom surface of the body ; The projector has a simple structure and wide applicability, and can be easily adjusted according to the required height and angle, so that the projection effect of the projector can be optimized.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

As shown in Figure 1, the projector of the present invention includes a body 1, an annular groove 2 provided on the bottom surface of the body 1, a slider 3 slidably connected to the annular groove 2, and an adjusting screw 4 pierced through the slider 3, The adjustment screw 4 is threadedly matched with the slider 3, and the length of the adjustment screw 4 protruding from the bottom surface of the body 1 can be fine-tuned by rotating the adjustment screw 4, and the adjusting screw 4 can be moved to slide the adjustment screw 4 and the slider 3 along the annular groove 2; the body 1 is also provided with a lens 5 for projection.

As shown in Figure 2, the left and right opposite side walls of the annular groove 2 are provided with grooves for accommodating the slider 3, and the two ends of the slider 3 are placed in the groove so that the slider 3 will not fall while sliding. . For the situation where the projector can be directly placed horizontally to achieve the best projection effect, the adjustment screw 4 should be rotated at this time to completely retract the adjustment screw 4 into the annular groove 2. Considering this situation and the convenience of storage, in specific implementation, the annular groove The depth of 2 should be greater than the length of adjusting screw 4.

Because the adjustment screw 4 and the slider 3 are threaded, the adjustment screw 4 can be unscrewed and then stored separately when not in use. When this is set, the depth of the annular groove 2 need not be greater than the length of the adjustment screw 4, while the adjustment screw 4 Various length specifications can also be set, so that the adjustment screw 4 of different specifications can be screwed into the slider 3 in different situations, so that the adjustment process of the projector is more convenient.

What Fig. 3 shows is the situation that the position of the lens 5 is lower than the horizontal line of the center of the projection screen 6, adjust the position of the projector so that the lens 5 is opposite to the projection screen 6, move the adjustment screw 4 to slide the adjustment screw 4 to a position close to the lens 5, Rotate the adjusting screw 4 so that the adjusting screw 4 protrudes from the bottom surface of the body 1, so that the lens 5 of the projector is lifted upwards, turn on the projector and fine-tune the adjusting screw 4 again, so that the projection effect of the projector on the projection screen 6 can reach the best , due to the weight of the projector itself, without the action of external force, the slider 3 will not slide in the annular groove 2 at this time, so that the placement of the projector is firm and not easy to shake.

What Fig. 4 shows is the situation that the position of the lens 5 is higher than the center horizontal line of the projection screen 6, the adjustment process at this moment is similar to the process in Fig. 3, just slide the adjustment screw 4 to the position away from the lens 5, so that the lens of the projector 5 projected downward.

Figure 5 shows that the desktop is uneven. At this time, one side of the bottom surface of the body 1 should be in contact with the desktop, and then the adjusting screw 4 is moved to slide the adjusting screw 4 to a position away from the side, and the adjusting screw 4 is rotated to make the adjusting screw 4 Protrude from the bottom surface of the body 1 and make contact with the desktop to compensate for the height difference, thereby keeping the projector level.

In the situations shown in Fig. 3, Fig. 4 and Fig. 5, after the projector is adjusted, one side of the bottom surface of the body 1 is in contact with the desktop, and at the same time, an adjusting screw 4 is also in contact with the desktop, forming a structure similar to a three-point support. structure, so that the projector can achieve a stable effect; in some special cases, the projection angle of the projector needs special adjustment, at this time, it can be realized by setting two sliders 3 and two adjustment screws 4, and the bottom surface of the body 1 after adjustment When one corner of the two adjustment screws 4 is in contact with the desktop, the two adjustment screws 4 are also in contact with the desktop. At this time, the position of the two adjustment screws 4 in the annular groove 2 and the length of the two adjustment screws 4 protruding from the bottom surface of the body 1 can be fine-tuned. The height and angle of lens 5.

Those skilled in the art will appreciate that the embodiments described here are to help readers understand the principle of the utility model, and it should be understood that the protection scope of the utility model is not limited to such specific statements and examples. Those skilled in the art can make various other specific modifications and combinations based on the technical revelations disclosed in the utility model without departing from the essence of the utility model, and these variations and combinations are still within the protection scope of the utility model.
