DETAILED DESCRIPTION
[0016] The following is combined with Figure 1-4 This application is described in further detail.
[0017] The embodiment of the present application discloses a placard that is convenient for adjusting the angle. Figure 1-4, including a base 1, a fixed cover 2 and a placard body 3, the fixed cover 2 is located at the top of the base 1, and both ends of the top of the base 1 are provided with mounting parts 4 for fixing the fixed cover 2, and the two mounting parts 4 are composed of a card plate 41 and a first inner hexagonal bolt 42. Both ends of the bottom of the fixed cover 2 are provided with a card slot, and the two card plates 41 are fixedly connected to the two ends of the top of the base 1 respectively. The two card plates 41 are movably engaged in the inside of the two card slots, and the two first inner hexagonal bolts 42 are rotated to penetrate the two sides of the fixed cover 2 respectively. The two first inner hexagonal bolts 42 are respectively threadedly connected with the two card plates 41, so that the fixed cover 2 can be fixedly installed on the base 1, and the base 1 The inner movement is provided with a movable disk 51, and both ends of the inner top wall of the fixed cover 2 are fixedly connected to the limiting posts 52, and the two limiting posts 52 pass through the movable disk 51, and the bottom ends of the two limiting posts 52 are in conflict with the top of the base 1. The two limiting posts 52 can make the movable disk 51 only move up and down inside the fixed cover 2. The outer surface of the middle part of the two limiting posts 52 is movably sleeved with a conflict spring 53, and the two ends of the two conflict springs 53 respectively conflict with the inner top wall of the fixed cover 2 and the top of the movable disk 51. The two conflict springs 53 can apply a resistance force to the movable disk 51 during the opening process, so that the movable disk 51 will not move upward at will inside the fixed cover 2;
[0018] Reference Figure 2 、 Figure 3 and Figure 4 The middle part of the bottom end of the placard body 3 is fixedly connected with a rotating column 54, and the bottom end of the rotating column 54 movably passes through the middle part of the top end of the fixed cover 2. The bottom end of the fixed cover 2 is provided with a connecting piece 6 for movably connecting with the movable disk 51. The bottom end of the connecting piece 6 is fixedly connected with a gear block 55, so that the gear block 55 can rotate synchronously with the rotating column 54. The middle part of the top end of the base 1 is fixedly connected with an internal gear ring 56, and the gear block 55 is engaged with the internal gear ring 56. When the placard body 3 is pulled to drive the rotating column 54 to rise, the rotating column 54 drives the movable disk 51 and the gear block 55 through the connecting piece 6. The block 55 moves upward at the same time, and the two interference springs 53 are compressed by the movable disk 51, and the gear block 55 comes out from the inside of the inner gear ring 56, and then the placard body 3 can be rotated horizontally to adjust the angle. After the adjustment is completed, the placard body 3 is released. At this time, the two interference springs 53 will open and interfere with the movable disk 51, driving the connecting piece 6, the rotating column 54 and the gear block 55 to move downward. The gear block 55 will be engaged with the inside of the inner gear ring 56, fixing the connecting piece 6 and the rotating column 54, and preventing the rotating column 54 from driving the placard body 3 to rotate at will.
[0019] Reference Figure 2 and Figure 4The connecting member 6 consists of a connecting shaft 61 and a limiting ring 62. A convex circular groove is provided in the middle of the bottom end of the movable disk 51. The connecting shaft 61 rotates through the convex circular groove. The top end of the connecting shaft 61 is fixedly connected to the bottom end of the rotating column 54, and the bottom end of the connecting shaft 61 is fixedly connected to the top end of the gear block 55. The connecting shaft 61 can connect the gear block 55 and the rotating column 54. The limiting ring 62 is fixedly sleeved on the outer surface of the top end of the connecting shaft 61. The bottom end surface of the limiting ring 62 fits with the top surface of the movable disk 51, so that the connecting shaft 61 can only rotate horizontally inside the movable disk 51.
[0020] Reference Figure 1 and Figure 2 , the four corners at the top of the base 1 are all provided with circular holes, and the inside of the four circular holes are movably penetrated by second hexagon socket bolts 7. By rotating the four second hexagon socket bolts 7 and threading them into the peripheral mounting frame, the base 1 can be fixedly installed on the peripheral mounting frame.
[0021] The implementation principle of the angle-adjustable placard of the embodiment of the present application is as follows: when the angle of the placard body 3 needs to be adjusted, the placard body 3 is pulled to drive the rotating column 54 upward, and the rotating column 54 drives the movable disk 51 and the gear block 55 to move upward simultaneously through the connecting shaft 61. At this time, the two contact springs 53 are compressed by the movable disk 51, and the gear block 55 is released from the inside of the inner gear ring 56. Then, the placard body 3 can be rotated horizontally to adjust the angle.
[0022] After the adjustment is completed, the placard body 3 can be slowly loosened. At this time, the two resistance springs 53 will expand and resist the movable disk 51, driving the connecting shaft 61, the rotating column 54 and the gear block 55 to move downward. The gear block 55 will be engaged with the inside of the inner gear ring 56 to fix the connecting shaft 61 and the rotating column 54, preventing the rotating column 54 from driving the placard body 3 to rotate at will.
