Description

Canvas clamping system convenient for single roller

Technical Field

The utility model relates to the technical field of single-roller rolling picture systems and mechanical clamping devices, in particular to a canvas system convenient to clamp by a single roller.

Background

The canvas is installed in the single roller system in the existing subway rail region lamp box, and because the cloth is adhered to the canvas in the mode of the transparent adhesive tape, the canvas is often not adhered and is inclined, and the technical level of an operator is high when the canvas is adhered, and the efficiency is low. In addition, if the advertisement canvas falls off, the advertisement canvas will have adverse effects, and economic disputes are easily caused.

However, the existing single-roller canvas clamping system has the following problems in the using process: because the existing canvas is fixed in a transparent adhesive tape mode during installation, the canvas is easy to drop. For this reason, a corresponding technical scheme needs to be designed to solve the existing technical problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a canvas clamping system with a single roller, which solves the technical problem that the canvas is easy to drop because the canvas is fixed in a transparent adhesive tape way during the installation of the existing canvas, improves the convenience of installation and replacement and meets the actual use requirement.

In order to achieve the purpose, the utility model provides the following technical scheme: the novel painting box comprises a box body, the box is provided with the single roller bearing in being close to top one side, be provided with on the single roller bearing and draw the cloth, be provided with clamping device on the bottom of drawing the cloth, clamping device includes backing plate and special material strip, the backing plate is provided with the canvas clamp at the opposite side opposite with special material strip, be provided with the canvas between canvas clamp and the backing plate.

In a preferred embodiment of the present invention, a through hole is formed at one side of the bottom of the box body for use with the clamping device, and a controller is disposed at a side of the box body for use with the single roller.

As a preferred embodiment of the present invention, the backing plate, the guiding cloth, and the special material strip are sequentially fixed by rivets, the special material strip is an aluminum profile strip and is subjected to silver-white oxidation treatment, a torsion spring is arranged between the top of the canvas clip and the backing plate, and the bottom of the canvas clip on the side facing the backing plate is provided with a plurality of steel nails.

Compared with the prior art, the utility model has the following beneficial effects:

through the improvement of the picture clamping system, the friction force to the canvas is increased by utilizing the resilience combination principle of a mechanical structure and a torsion spring. Therefore, the picture can be quickly replaced by one person, and the canvas is ensured not to fall off. The personnel overhead is reduced, the quality of service customers is improved, technical support is provided for company operation, and therefore the problem that the canvas easily falls is solved.
