Embodiment Construction

[0010] The present invention will now be further described in conjunction with specific examples, and the following examples are intended to illustrate the present invention rather than further limit the present invention.

[0011] like figure 1 The guardrail shown in the picture can be changed, including the upper cross bar 1, the lower cross bar 2 and the grid bar 3. Openings 4 are provided on the inner side of the lower cross bar 2, and openings 4 are provided on one side of the grid bar 3.

[0012] like Figure 2~4 The upper crossbar 1, the lower crossbar 2 and the grating bars 3 shown are cylindrical, elliptical cylinder or rectangular cylinder structures.

[0013] In actual use, first install the picture in the opening 4 of the lower cross bar 2, then clamp the opening 4 of the grid bar 3 on the left and right sides of the picture, and finally install the cross bar 1 through the opening 4 above the picture. The whole installation process is simple and convenient .

Abstract

The invention relates to a picture-changeable guardrail. The guardrail comprises an upper cross bar, a lower cross bar and grid bars. The upper cross bar, the lower cross bar and the grid bars are in hollow cylinder, elliptic cylinder or rectangular cylinder structures, openings are formed in the insides of the upper cross bar and the lower cross bar, and openings are formed in the sides of the grid bars. The guardrail has the advantages of being simple in structure, convenient to mount, capable of changing pictures and provided with functions such as environment beautifying and advertising.

Description

technical field [0001] The invention relates to a guardrail with replaceable pictures. Background technique [0002] Guardrails are widely used on sidewalks, but the guardrails of the prior art are generally limited to restricting the range of action of pedestrians, and they are strong and durable, and less consideration is given to other functions. With the progress of society and the improvement of people's living standards, people have also put forward higher requirements for guardrails. That is to say, guardrails should not only be limited to restricting the range of pedestrians' actions, but also have the function of beautifying the environment, and can also generate commercial value such as advertisements. Contents of the invention [0003] The technical problem to be solved by the present invention is: based on the above problems, the present invention provides a guardrail with replaceable pictures. [0004] A technical solution adopted by the present invention to...
