offer pin-and-hole 13 on the lateral wall 11 of holder 1, cross-under limited location pin 36 in this pin-and-hole 13, the outboard end of this position-limitting pin 36 is embedded in the spacing elongated slot 32 of offering on dowel bushing 3, the bearing of trend of spacing elongated slot 32 is on horizontal plane, and the length direction along dowel bushing 3 extends, when dowel bushing 3 moves with respect to holder 1, position-limitting pin 36 and spacing elongated slot 32 actings in conjunction, guarantee dowel bushing 3 along the direction of motion of holder 1 on horizontal plane, two position-limitting pins 36 can be installed on the lateral wall 11 of holder 1, two position-limitting pins 36 are embedded in respectively in the spacing elongated slot 32 at dowel bushing 3 two ends, for dowel bushing 3 plays good guide effect, in order to prevent that finely tuning screw rod 4 stuck phenomenon occurs when driving dowel bushing 3 motion.Spacing elongated slot 32 is stepped, the head of a nail of position-limitting pin 36 mounts the end difference of spacing elongated slot 32, it is smooth periphery that one section surface is arranged between the head of a nail of position-limitting pin 36 and threaded portion, the part of this smooth periphery is placed in the spacing elongated slot 32 less parts in end difference aperture, thereby prevents that dowel bushing 3 and portable plate 2 break away from.
Above-mentioned angular adjustment apparatus also includes a lock-bit pin 6, this lock-bit pin 6 extends along short transverse, its bottom cross-under is fixed on portable plate 2, and in the arc guide groove 16 that the cross-under of sliding is offered on holder 1, when needing to rotate portable plate 2 and holder 1, unscrew lock-bit pin 6, make portable plate 2 and the holder 1 can relative motion, after adjusting the display screen angle, can screw lock-bit pin 6, lock-bit pin 6 is fixed seat 1, makes holder 1 and portable plate 2 holding positions fix.The extension track of the arc chute on the extension track of above-mentioned arc guide groove 16 and holder 1 is consistent.
When the needs display screen box body swings certain angle, latch 5 is outwards extracted, make it break away from one of them groove 22, promoting portable plate 2 makes it rotate with respect to holder 1, after the display screen box body that connects on portable plate 2 turns to correct position, release is to latch 5 externally applied forces, latch 5 is under the effect of spring 51, its medial extremity is embedded in corresponding groove 22 again, afterwards, screw lock-bit pin 6, portable plate 2 is fixing with holder 1, and the angle that makes the display screen box body that is connected on holder 1 and portable plate 2 be needs is put.Yet, in said process, might be because the mismachining tolerance of display screen box body makes the angle of putting not accurate enough, at this moment, unscrew lock-bit pin 6, adjust fine setting screw rod 4, drive dowel bushing 3 motions, 5 of latches that are inserted on dowel bushing 3 can promote portable plate 2 with respect to holder 1 rotation minute angle, make two formula display screen box bodies can turn to accurately needed angle, thereby eliminate the defective that the display screen box body mismachining tolerance is brought.
offer the arcwall face 53 of an indent in a side of the medial extremity of latch 5, when the needs display screen box body swings an other angle, latch 5 is rotated 180 °, make latch 5 outer ends scripts bending end up down, the arcwall face 53 of latch 5 medial extremitys namely rotates 180 °, thereby change the degree of depth that latch 5 front ends enter into corresponding groove 22, the sidewall of the front end extruding groove 22 of latch 5, make portable plate 2 rotate a small angle, and the latch 5 after rotating can be locked with dowel bushing 3 and portable plate 2, make portable plate 2 keep relative fixing with holder 1, in said structure, latch 5 is rotated different angles, the degree of depth that latch 5 is inserted in groove 22 is different, thereby realize the adjustment of different vernier angles.
Spacing elongated slot 32 is stepped, the head of a nail of position-limitting pin 36 mounts the end difference of spacing elongated slot 32, thereby prevent that dowel bushing 3 and portable plate 2 break away from, it is smooth periphery that one section surface is arranged between the head of a nail of position-limitting pin 36 and threaded portion, and the part of this smooth periphery is placed in the spacing elongated slot 32 less parts in end difference aperture.
Those skilled in the art can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection range of the utility model claim.
