DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 As shown, a multi-angle adjustment structure of an instrument comprises a lower connecting plate 1, on which a first column 2 and a second column 4 are fixedly mounted, the first column 2 and the second column 4 are arranged horizontally and parallel, an instrument housing 3 is arranged between the first column 2 and the second column 4, a mirror surface 10 is inlaid on the front of the instrument housing 3, two rotating shafts 5 are fixedly connected to the opposite side surfaces of the instrument housing 3, the interior of the second column 4 is hollow, the other end of the rotating shaft 5 close to the side of the first column 2 is rotatably connected to the first column 2, and the other end of the other rotating shaft 5 is rotatably penetrated into the second column 4, one end of the rotating shaft 5 located in the second column 4 is fixedly connected to a worm gear 6, a connecting shaft 7 is rotatably connected between the inner walls of the opposite sides of the second column 4, a worm 8 is fixedly sleeved on the outer surface of the rotating shaft 7, the worm 8 is meshed and connected with the worm gear 6, one end of the connecting shaft 7 is rotatably penetrated out of the outer surface of the second column 4, and one end of the connecting shaft 7 located outside the second column 4 is fixedly connected to a rotating handle 9;

[0021] When the angle of the instrument needs to be adjusted, it is only necessary to rotate the handle 9, thereby driving the connecting shaft 7 to rotate synchronously, and the worm 8 will rotate synchronously with the connecting shaft 7, so the worm 8 can mesh with the worm wheel 6 to rotate, so the instrument housing 3 rotates with the rotating shaft 5, thereby achieving the purpose of adjusting the angle of the instrument, and there is no need to remove the instrument connecting parts to adjust the angle of the instrument. Under the transmission of the worm gear, the worm gear has a self-locking effect, so the instrument angle does not need to be additionally fixed after adjustment. The operation steps when adjusting the angle of the instrument are reduced.

[0022] More preferably, a shading plate 12 is provided on the front of the instrument housing 3, and a retraction cavity 11 is opened in the inner wall of the instrument housing 3. The shading plate 12 slides into the retraction cavity 11 on the side close to the instrument housing 3, and a limiting slide 13 is fixedly connected to the side of the shading plate 12 located in the retraction cavity 11. The limiting slide 13 slides in the retraction cavity 11, and a contact slide bar 14 is fixedly connected to the surface of the limiting slide bar 13 on the side facing away from the shading plate 12, and the other end of the contact slide bar 14 slides through the outer surface of the instrument housing 3, and a tension spring 15 is fixedly connected between the limiting slide bar 13 and the inner wall of the retraction cavity 11, and the tension spring 15 is movably sleeved on the outer surface of the contact slide bar 14. When the tension spring 15 is not affected by the tension force, the tension spring 15 will form a tension force on the limiting slide bar 13, so that most of the shading plate 12 is retracted into the retraction cavity 11.

[0023] More preferably, a trigger block 16 is fixedly connected to the upper surface of the lower connecting plate 1, and the upper side of the trigger block 16 is in the shape of a right triangle. The trigger block 16 is located on the rear side of the instrument housing 3, and the end of the contact slide bar 14 located outside the instrument housing 3 contacts the inclined surface of the trigger block 16. When the instrument housing 3 rotates clockwise, the contact slide bar 14 rotates synchronously with the instrument housing 3. At this time, the contact slide bar 14 contacts the inclined surface of the trigger block 16 and slides along the inclined surface of the trigger block 16. During the sliding process, the inclined surface of the trigger block 16 squeezes the contact slide bar 14, thereby pushing the shading plate 12 out of the instrument housing 3. In this way, the extension length of the shading plate 12 can be automatically controlled after the angle of the instrument is adjusted, thereby further improving the shading effect of the instrument and ensuring the use effect of the structure.

[0024] More preferably, the end of the contact slide bar 14 located outside the instrument housing 3 is hemispherical, which increases the smoothness of the outer surface of the end of the contact slide bar 14 that contacts the inclined surface of the trigger block 16, reduces the friction generated when the contact slide bar 14 slides along the inclined surface of the trigger block 16, and avoids the problem of jamming caused by excessive friction between the contact slide bar 14 and the inclined surface of the trigger block 16, thereby ensuring the stability of the mechanism during operation.

[0025] Working principle: Just turn the handle 9 to drive the connecting shaft 7 to rotate synchronously, and the worm 8 will rotate synchronously with the connecting shaft 7, so the worm 8 can mesh with the worm wheel 6 to rotate, so the instrument housing 3 rotates with the rotating shaft 5, so as to achieve the purpose of adjusting the instrument angle;

[0026] At the same time, when the instrument housing 3 rotates clockwise, the contact slide bar 14 will rotate synchronously with the instrument housing 3. At this time, the contact slide bar 14 will contact the inclined surface of the trigger block 16 and slide along the inclined surface of the trigger block 16. During the sliding process, the inclined surface of the trigger block 16 will squeeze the contact slide bar 14, thereby pushing the visor 12 out of the instrument housing 3.
