[0033] Reference Figure 1 , Figure 2 , Figure 4 The inner wall of the bottom end of the chassis 1 is rotatably connected with a rotating rod 56, and the rotating rod 56 provides support. The leg 5 is fixedly connected to the bottom end of the rotating rod 56. An adjustment component is arranged on the right side of the rotating rod 56, and the adjustment component includes a positioning groove 55. The positioning groove 55 provides a sliding rod 51 for sliding. The inner wall of the positioning groove 55 is provided with a guide groove. The inner wall of the guide groove is slidably connected with a guide block. The guide groove and the guide block cooperate to support the sliding rod 51. The inner wall of the positioning groove 55 is slidably connected with the sliding rod 51, and the sliding rod 51 drives the limit rod 53 to move.

[0034] Reference Figure 1 , Figure 3 , Figure 4 A circular groove 52 is provided on the right side of the lower end of the chassis 1, and there are multiple groups of circular grooves 52. The multiple groups of circular grooves 52 can cooperate with the limit rod 53 to play an adjusting role. The positioning groove 55 is provided on the right side of the rotating rod 56. The guide block is fixedly connected to the left side of the sliding rod 51. The sliding rod 51 and the rotating rod 56 are elastically connected by a spring 54. The limit rod 53 is driven to move and release the limit of the chassis 1 by pulling the sliding rod 51 and stretching the spring 54. At the same time, the limit rod 53 can be reset and slide into the circular groove 52 by the reverse force of the stretched spring 54 to limit the chassis 1. The top end of the sliding rod 51 is fixedly connected to the limit rod 53, and the limit rod 53 slides on the inner wall of the circular groove 52. The angle of the chassis 1 can be adjusted by moving the limit rod 53 out of the circular groove 52.

The two groups of ventilation plates 45 can circulate, thereby improving the heat dissipation effect. A slide groove 43 is provided on the right side of the ventilation plate 45. A handle 41 is penetrated and slidably connected to the right side of the door panel 4. The left end outer wall of the handle 41 is fixedly connected to a limiting block 42. The handle 41 can drive the limiting block 42 to move and slide out of the limiting groove 44 and the slide groove 43, thereby releasing the limit of the door panel 4, so that the door panel 4 can be moved for ventilation and heat dissipation. A limiting groove 44 is provided on the left inner wall of the right side of the ventilation plate 45 close to the slide groove 43. The limiting block 42 slides on the inner wall of the slide groove 43. The limiting block 42 slides on the inner wall of the limiting groove 44.

At the same time, after the limit block 42 is rotated and aligned with the slide groove 43, the handle 41 can be pulled to the right to drive the limit block 42 to slide out of the limit groove 44 and the slide groove 43 and slide to the left side of the door panel 4. At this time, the limit of the door panel 4 can be released. At this time, the door panel 4 is moved downward. At this time, the ventilation plate 45 can be used in conjunction with the heat sink 6 for heat dissipation. The two sets of ventilation plates 45 are connected to achieve a circulation effect, thereby improving the heat dissipation effect and preventing the motor in the chassis 1 from heating up, thereby improving the use effect and service life of the chassis 1.

[0037] When the chassis 1 is installed on an uneven parking lot, the spring 54 can be stretched by pulling the slide bar 51 to drive the limit rod 53 to move out of the circular groove 52, thereby releasing the limit of the chassis 1. At this time, the angle of the chassis 1 can be adjusted. After the chassis 1 is adjusted to a position where the display screen 2 is convenient to observe, the slide bar 51 and the limit rod 53 can be reset by the reverse force of the stretched spring 54. The chassis 1 is limited by the limit rod 53 being reset and sliding into the circular groove 52. At this time, the display screen 2 can be conveniently observed, thereby improving the use effect of the display screen 2 and the applicability of the overall device.
