technical field

The utility model relates to the field of auxiliary devices for publicity and display, in particular to a portable display frame for outdoor poster display, specifically, a display frame with wind resistance stability.

Background technique

A display stand is a simple device used for marketing, publicity, advertising, and simple support for posters that need to be displayed. Although the existing portable display racks are of different sizes, their structure and type are relatively unified. Usually, rods with different lengths without roots are connected by plastic connecting plates, four of which are used to hang display posters, and the other One is used to support the whole display rack. Because the supporting display racks are in the shape of crossing each other, people usually call them "X display racks". Simple shape design, convenient transportation, easy storage, simple installation, economical and practical, light and fast advertising materials, weighing less than 1.5KG, can install a complete X display rack in less than a minute, very convenient X display rack is a metal round Core, aluminum alloy joint U-shaped feet, X-frame size is 60X160cm/80X180cm mounted 22CC PVC, high-frequency welded pipe aluminum alloy disc electroplating sleeve, black non-woven packaging bag, weight: about 0.5kg, with light and fast It is very convenient to install the whole X display rack in less than a minute. The purpose of the X display stand is the same as that of the roll-up banner. It is an advertising material for public places, events, gatherings or shops, and it is also a display item for wedding celebrations. It is small and exquisite, easy to carry, removable, and the screen can be replaced. Economical X display rack, the picture adopts screen printing method, the whole component does not need to be assembled, and it is equipped with adjustable angle brackets.

detailed description

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example 1:

As shown in accompanying drawings 1, 2, and 3 of the present utility model, a display stand with wind resistance stability includes a base 1 for placing on the ground, the base 1 is composed of two symmetrical semicircles, and the inside It has an annular cavity, and the annular cavity communicates with the upper part of the base 1; the center of the cavity of the base 1 is provided with a turntable 7, and two connecting rods 11 are mounted symmetrically on the turntable 7, and the connecting rods The free ends of 11 are all plugged with connecting blocks 8, which are accommodated in the annular cavity and can rotate freely relative to the turntable 7, and the connecting blocks 8 are detachably connected with supports perpendicular to the base 1 A pole 2, the support pole 2 is provided with a plurality of adjustable hooks 3 for fixing posters.

Working principle: Hang the four corners of the poster to be displayed on the hook 3, fix the two hooks 3 near the base 1, adjust the two hooks 3 on the upper part of the support rod 2, until the poster is tensioned and fixed Hook 3. At this time, the support rod 2 can be rotated at will. Since the poster and the support rod 2 are fixedly connected, the entire poster can also rotate freely relative to the base 1 . When the utility model hangs the poster and places it in any display environment, if there is any angle of wind blowing to the poster, the poster will generate resistance to the wind. The difference is that at the same wind speed, the greater the force-bearing area, the greater the wind resistance Larger, the smaller the force area, the smaller the wind resistance. Therefore, no matter whether the poster is in the direction facing the wind, that is, facing the wind, or facing the direction of the wind blowing sideways, the poster can be in the crosswind position under the action of the wind. Since the wind resistance at the side wind position is the smallest, its wind resistance and wind resistance stability are the best. The problem that the existing display rack is easy to be repeated is solved.
