[0002] A projector is an optical instrument that uses optical elements to magnify the contour of a workpiece and project it onto a screen. It can use transmitted light for contour measurement and reflected light to measure the surface shape of blind holes and observe the surface of parts. An interactive projection system can provide a more realistic and immersive experience. Users can interact directly with the projected image through gestures, touch, etc., making it more immersive.

This technology discloses "including a projection device, a lens plugged into the front of the projection device, the top of the projection device is fixedly connected to a connection frame, the connection frame is movably connected to a bidirectional screw inside, the right end of the bidirectional screw penetrates one side of the connection frame and is fixedly connected to a rotating wheel, the top of the projection device is movably connected to a transmission rod, the number of the transmission rods is two, the front end of the transmission rod is fixedly connected to a claw sleeved on the surface of the lens, the rear end of the transmission rod is fixedly connected to an extrusion plate sleeved on the surface of the bidirectional screw, the surface of the bidirectional screw is threadedly connected to a screw sleeve, the number of the screw sleeves is two and both are located on the inner side of the extrusion plate, etc., which has the technical effects of being able to increase the connection method between the existing projection device and the lens, assisting the mutual plug-in method for connection, and preventing the lens from being affected by vibration and becoming loose. ";

[0004] With respect to the above-mentioned related technologies, the inventors believe that the existing interactive screen projection device structure does not have a mechanism for adjusting the height of the projection device. During projection, in order to achieve a better projection effect, the height position of the projection needs to be adjusted according to actual conditions. There is no lifting mechanism, which makes it inconvenient to freely adjust the projection height of the projection device. Secondly, the existing projection device is not provided with a light strip assembly. During projection, the weak light will affect the projection effect of the projection device. There is no light strip assembly, which makes it inconvenient for the light to be evenly scattered during projection, thereby reducing the projection effect of the projection device.

[0034] The lifting mechanism 2 includes a support seat 22 and two long rods 28. The bottom end of the support seat 22 is fixedly connected to one side of the lower inner wall of the base 1. The two ends of the two long rods 28 are rotatably connected to the inner walls of both sides of the base 1. The top end of the support seat 22 is fixedly connected to a motor 21. The support seat 22 plays a role in facilitating the support of the motor 21, and the motor 21 plays a role in driving the lifting mechanism 2.

[0035] The output end of the motor 21 is fixedly connected to a worm 27, and the outer surface of the worm 27 is provided with two threads. The lower inner wall of the base 1 is fixedly connected to a support shell 201 used in conjunction with the worm 27. The end of the worm 27 facing away from the output end of the motor 21 is rotatably connected to the inner wall of one side of the support shell 201, so that the output end of the motor 21 drives the worm 27 to transmit. At the same time, the support shell 201 plays a role in facilitating the positioning of the worm 27 during transmission.

[0036] The outer surface of the worm 27 is meshed with two worm wheels 26. The outer surface thread directions of the two worm wheels 26 match the thread directions of the outer surface of the worm 27. The two worm wheels 26 are respectively fixedly sleeved on the outer surfaces of the two long rods 28, so that the worm 27 drives the worm wheel 26 to rotate, and the rotation of the worm wheel 26 drives the long rod 28 to rotate.

[0037] The outer surfaces of the two long rods 28 are fixedly sleeved with two first connecting rods 29, so that the long rods 28 rotate to drive the first connecting rods 29 to rotate. The bottom end of the connecting plate 5 is fixedly connected with a hinge seat 25 used in conjunction with the second connecting rod 202. The four hinge seats 25 are all in an inverted "U" shape, and the four hinge seats 25 are distributed in a rectangular array. The inner walls on both sides of the four hinge seats 25 are hinged with the second connecting rod 202 used in conjunction with the first connecting rod 29 through a rotating shaft, and the corresponding first connecting rod 29 and the second connecting rod 202 are hinged through a rotating shaft, so that the first connecting rod 29 rotates to cooperate with the second connecting rod 202 and the hinge seat 25 to move the connecting plate 5.

[0038] Two guide blocks 24 are fixedly connected to both ends of the connecting plate 5. Vertical grooves 23 used in conjunction with the four guide blocks 24 are provided on the inner walls of both sides of the base 1. The outer surfaces of the four guide blocks 24 are slidably connected to the inner walls of the four vertical grooves 23 respectively. The vertical grooves 23 cooperate with the guide blocks 24 to facilitate the guiding of the connecting plate 5 when it moves, so that the connecting plate 5 can move up and down in the vertical direction, thereby freely adjusting the height of the projection.

[0039] The light strip assembly 3 includes a shell 35, the bottom end of the shell 35 is fixedly connected to the top end of the connecting plate 5, and the two ends of the shell 35 are respectively slidably connected to the inner walls of the two sides of the base 1, so that the shell 35 can move up and down when moving;

[0040] The upper and lower inner walls of the housing 35 are fixedly connected with three groups of diffuse reflection light strips 31, and the corresponding three groups of diffuse reflection light strips 31 are distributed at equal intervals, so as to make the use effect of the diffuse reflection light strips 31 better. The inner wall of the housing 35 is fixedly connected with two white painted iron plates 34, and the two white painted iron plates 34 are distributed in a mirror image, and the white painted iron plates 34 enhance the brightness of the projection;

[0041] One end of the opposite sides of the two white painted iron plates 34 are fixedly connected with a customized raw material model 33 used with the diffuse reflection light strip 31. Both ends of the customized raw material model 33 are fixedly connected with partitions 32. The outer shell 35 and the two partitions 32 are made of transparent acrylic material, so that the light scattered by the diffuse reflection light strip 31 is more uniform, thereby improving the projection effect of the projection equipment.

[0042] Working principle: First, when the height of the projection of the projection device needs to be adjusted, the motor 21 is started through the lifting mechanism 2, and the output end of the motor 21 drives the worm 27 to transmit, and at the same time, the support shell 201 plays a role in facilitating the positioning of the worm 27 during transmission. The worm 27 drives the worm wheel 26 to rotate, and the rotation of the worm wheel 26 drives the long rod 28 to rotate;

[0043] The long rod 28 rotates to drive the first connecting rod 29 to rotate, and the first connecting rod 29 rotates to cooperate with the second connecting rod 202 and the hinge seat 25 to move the connecting plate 5. At the same time, the vertical groove 23 cooperates with the guide block 24 to facilitate the guiding of the connecting plate 5 when it moves.

[0044] The height position of the connecting plate 5 is changed so that the projection height of the projector body 4 is changed;
