[0030] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0031] With the development of cities and the advancement of science and technology, traditional lighting poles have been given more functions to realize intelligent applications of one pole for multiple uses. The current practice is to directly mount corresponding equipment on the original light poles, such as cameras, display screens, light boxes, etc. This is simple, convenient and low-cost, and is a common method in the industry.

[0032] However, this method needs to consider the design bearing capacity of the original lamp pole and foundation. Most mounting methods completely rely on the bearing capacity of the original lamp pole and foundation. This requires the mounting work to consider the bearing capacity and possible safety hazards, especially for display screens with a large windward area.

[0033] The utility model mainly provides a display screen installation component and a lamp pole, so as to overcome the defect that the display screen is mounted on the original lamp pole and completely relies on the force of the original lamp pole and the foundation, and improves the stability and safety of the display screen installed on the original lamp pole.

[0034] 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0035] Embodiment 1

[0036] See also Figure 2 , 3 As shown, in this embodiment of the utility model, a support frame 20 is two support frames that are symmetrical left-right / front-back, wherein the support frame includes a frame body 203, a notch 206 is opened on one side of the frame body 203, and the notch 206 is used to place and fix the rod body; a support plate 202, the support plate 202 is fixedly arranged on the bottom surface of the frame body 203; and a plurality of anchor columns 201, which are fixedly connected to the bottom surface of the support plate 202 and plugged into the ground.

[0037] In addition, the size of the frame 203 and the support plate 202 can be flexibly set according to the size of the original rod body, which can not only meet the needs of the original cylindrical rod body, but also meet the needs of the original rectangular rod body, thereby realizing the need to install external equipment on rod bodies of different shapes in different working scenarios.

[0038] It should be noted that the frame 203 can be a frame or a flat plate, and any structure that can provide a certain contact surface and be fixedly connected to the support plate 202 can constitute the support frame 20 of the present invention. The user can flexibly set the specific structure of the frame 203 according to the needs of the actual working scene.

[0039] When in use, the support frame 20 will be pre-buried below the ground, and the rod body will be fixed around it through the notches set on the two support frames 20 that are symmetrical left and right / front and back, with the support plate 202 in contact with the ground, and the anchor column 201 inserted below the ground. The structure thus formed is equivalent to increasing the contact area between the original rod body and the ground, thereby sharing the gravity and force on the original rod body. Therefore, when mounting external equipment on the original rod body, the use of the support frame structure of the utility model can overcome the defect that the force on the original rod body and the foundation cannot be alleviated when the external equipment is mounted on the original rod body, thereby improving the stability of the original rod body.

[0040] Embodiment 2
