The middle of the left and right sides of the projector 1 is connected to the inner side of a set of guide strips 2. The middle of the bottom end of the fixed top seat 9 is connected to the top end of the vertical slide 10. A slider 11 is vertically slidable on the inner side of the vertical slide 10. A driving mechanism is provided between the vertical slide 10 and the slider 11. The front side of the slider 11 is connected to the rear side of the connecting frame 12. The lower side of the connecting frame 12 is connected to the outer side of the mounting box 3 via a horizontal adjustment mechanism and a vertical adjustment mechanism. A set of guide slots 4 are connected to the middle of the left and right sides inside the mounting box 3. The guide slots 4 and guide strips 2 are detachably inserted. The upper front side of the mounting box 3 is connected via a hinge. Page 5 is movably connected to the top side of the top frame 6. A set of magnets 7 are connected to the left and right sides of the rear end of the top frame 6. A set of ferromagnetic blocks 8 are connected to the left and right sides of the front side of the bottom end of the mounting box 3, corresponding to each set of magnets 7. The fixed top seat 9 is fixed at the corresponding position on the roof of the classroom. During installation, the projector 1 can be inserted into the two sets of guide slots 4 in the mounting box 3 by the two sets of guide strips 2 respectively. After the projector 1 is moved to the rear position in the mounting box 3, the top frame 6 is closed under the constraint of the hinge 5, so that the two sets of magnets 7 and ferromagnetic blocks 8 are attracted respectively. The front side of the projector 1 is limited by the closing and fixing of the top frame 6. Then, the horizontal adjustment mechanism and the vertical adjustment mechanism are connected to the mounting box 3 for adjustment. The slider 11 slides vertically in the vertical slide frame 10 and is fixed in place by the drive mechanism. The whole is connected by the connecting frame 12 to form a stable support.

[0024] The drive mechanism includes a reciprocating motor 13, a threaded rod 14, and a threaded sleeve 15. The bottom end of the vertical slide 10 is connected to the top end of the reciprocating motor 13, and the output end of the reciprocating motor 13 is connected to the bottom end of the threaded rod 14. The threaded rod 14 is vertically rotatable within the vertical slide 10. A threaded sleeve 15 is provided on the inner side of the middle part of the slider 11, and the inner wall of the threaded sleeve 15 is screwed to the outer wall of the threaded rod 14. When the reciprocating motor 13 runs, it can cause the threaded rod 14 to rotate. The threaded rod 14, through screwing with the threaded sleeve 15, can be connected to the slider 11 to rise and fall accordingly.

[0025] The lateral adjustment mechanism includes a fixed circular block 16, a movable sleeve 17, a sliding sleeve 18, a push rod 19, a pull plate 20, and a spring 21. The bottom end of the connecting frame 12 is connected to the top end of the fixed circular block 16. The outer side of the fixed circular block 16 is movably connected to the inner side of the movable sleeve 17. The middle front part of the movable sleeve 17 is connected to the inner side of the sliding sleeve 18. The inner wall of the sliding sleeve 18 is slidably connected to the outer wall of the push rod 19. The front side of the push rod 19 is connected to the middle rear side of the pull plate 20. The outer side of the sliding sleeve 18 on the front side of the movable sleeve 17 is connected to the outer rear side of the pull plate 20 by the spring 21. When the pull plate 20 is pulled, it overcomes the spring 21 and causes the push rod 19 to slide forward inside the sliding sleeve 18, which releases the pressure on the fixed circular block 16 and allows the movable sleeve 17 to rotate outside the fixed circular block 16 for easy adjustment. After the pull plate 20 is released, the push rod 19 can support the outer side of the fixed circular block 16 under the elastic action of the spring 21, improving stability.

[0026] The vertical adjustment mechanism includes an extension frame 22, a constraint sleeve 23, a movable shaft 24, a tightening screw sleeve 25, a tightening screw 26, and a tightening handle 27. The left and right sides of the movable sleeve 27 are respectively connected to the inner side of a set of extension frames 22. The bottom ends of the two sets of extension frames 22 are respectively connected to the top end of a set of constraint sleeves 23. The inner side of each set of constraint sleeves 23 is movably connected to the outer side of a set of movable shafts 24. The two sets of movable shafts 24 are coaxially connected to the middle of the left and right sides of the mounting box 3. The middle front part of each set of constraint sleeves 23 is respectively connected to a set of tightening screw sleeves 25. The rear side is connected, and the inner wall of the tightening sleeve 25 is screwed to the outer wall of the tightening screw 26. The front side of the tightening screw 26 is connected to the middle of the rear side of the tightening handle 27. The constraint sleeve 23 is fixedly connected by the extension frame 22. The mounting box 3 can move synchronously inside the constraint sleeve 23 via two sets of movable shafts 24. It can be vertically flipped and adjusted. After it is in place, the tightening screw 26 can be rotated by turning the tightening handle 27. The tightening screw 26, after being screwed to the tightening sleeve 25, can act inward to tighten the corresponding position on the outside of the movable shaft 24.

[0027] It also includes pull rings 28, with the front side of each set of guide bars 2 connected to the rear side of a set of pull rings 28 respectively; by hooking the pull rings 28, the projector 1 can be connected to move, which is convenient for loading and unloading operations.

[0028] In summary, this easily disassembled teaching projector is used such that the fixed top bracket 9 is fixed at the corresponding position on the classroom ceiling. During installation, the projector 1 can be moved by hooking the pull ring 28. The projector 1 can be inserted into the two sets of guide rails 4 in the mounting box 3 by the two sets of guide rails 2 respectively. After the projector 1 is in the mounting box 3 and moves backward, the top frame 6 is closed under the constraint of the hinge 5, so that the two sets of magnets 7 are attracted to the ferromagnetic blocks 8 respectively. The top frame 6 is closed and fixed, limiting the front side of the projector 1. Then, when the pull tab 20 is pulled, the spring 21 is overcome and the top rod 19 slides forward inside the sliding sleeve 18, which can release the clamping of the fixed round block 16, allowing the movable sleeve 17 to rotate outside the fixed round block 16 for easy adjustment. After the pull tab 20 is released, it can be used to... Under the elastic action of spring 21, the top rod 19 supports the outside of the fixed round block 16. The extension frame 22 is fixedly connected to the constraint sleeve 23. The mounting box 3 can move synchronously inside the constraint sleeve 23 via two sets of movable shafts 24. It can be vertically flipped and adjusted. After it is in place, the tightening screw 26 can be rotated by turning the tightening handle 27. The tightening screw 26 can be screwed into the tightening sleeve 25 and can be tightened inward to the corresponding position on the outside of the movable shaft 24. When the reciprocating motor 13 runs, the threaded rod 14 can be rotated. The threaded rod 14 can be screwed into the threaded sleeve 15 and can be connected to the slider 11 for corresponding rise and fall. The slider 11 slides vertically in the vertical slide frame 10 and is fixed in place. The connecting frame 12 connects the whole to form a stable support.

[0029] The projector 1 and the reciprocating motor 13 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not go into detail about them here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
