Embodiment 1

[0028] like figure 1 As shown, the publicity display rack of this embodiment includes a seat body 10 and a publicity display rack body 20, the seat body 10 is arranged at both ends of the publicity display rack body 20, and the publicity display rack body 20 is clamped in the middle, thereby supporting the publicity display rack body 20 . The publicity display rack body 20 is provided with adsorption units and pasting units, each of which is provided with six adsorption units and pasting units, and one side of the adsorption units and the pasting units is arranged at intervals. The front of the publicity display rack body 20 is an adhesive surface, and the adhesive surface is used for pasting posters or publicity newspapers.

[0029] like figure 2 , image 3 As shown, both the adsorption unit and the pasting unit include a piston chamber, a negative pressure chamber and a piston 41 disposed in the piston chamber. The piston chamber includes a first piston chamber 23a and ...

Embodiment 2

[0037] Such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that in Embodiment 2, the rotating shaft 30 drives the piston 41 to slide through the crank 51 slider mechanism; its specific structure is: the rotating shaft 30 is welded with a crank 51, and the bottom of the piston 41 Welded with pull rod 53, pull rod 53 and crank 51 are connected by connecting rod 52, and one end of connecting rod 52 is hinged with the lower end of pull rod 53, and the other end of connecting rod 52 is hinged with the end of crank 51; Thereby make crank 51, connecting rod 52 and piston 41 form crank 51 slide block mechanism, then rotating shaft 30 can drive piston 41 to slide when rotating.

Abstract

The invention relates to the technical field of display, and particularly discloses a propaganda display rack, comprising a base and a propaganda display rack body, wherein a negative pressure chamberis arranged in the propaganda display rack body, the front of the propaganda display rack body is a sticky surface, a plurality of suction holes communicated with the negative pressure chamber are formed in the sticky surface; a piston chamber is arranged in the propaganda display rack body, a piston is arranged in the piston chamber, an air outlet one-way valve and an air inlet one-way valve arearranged on the side wall of the piston chamber; a rotating shaft is rotatably connected to the base, a torsional spring sleeves the rotating shaft, and a pedal capable of driving the rotating shaftto rotate is connected to the rotating shaft; a sticky block is arranged in the negative pressure chamber, the sticky block runs through the front of the propaganda display rack body and is capable ofsliding along a direction vertical to the front of the propaganda display rack body, a compressed spring abutting against the sticky block is arranged in the negative pressure chamber, and a pressurerelease valve capable of releasing pressure of the negative pressure chamber is arranged at the bottom of the propaganda display rack body. Suction force is formed to propaganda newspaper by the suction holes, so as to be convenient for adjusting and flattening the propaganda newspaper, and avoid damage of the propaganda newspaper.

Description

technical field [0001] The invention relates to the technical field of display, in particular to a publicity display rack. Background technique [0002] Display rack is also known as display rack, promotion rack, portable display and data rack, etc. The display rack is based on the characteristics of the displayed products, and the matching product promotion display rack is designed, coupled with creative LOGO signs, to make your products stand out. In front of the public, thereby increasing the role of advertising for products. [0003] Posters or posters are usually pasted on the side of the display rack with glue, usually the glue is applied to the back of the poster, and then attached to the display rack. Since the position of the poster needs to be adjusted and flattened during the pasting process, it will have a pulling effect on the poster, and in the process, it is easy to cause wrinkles on the poster. And because the glue has a wetting effect on the poster, it is ...
