Uniform Canvas Holder

Abstract

The invention discloses a compensating clamp holder for a canvas. The compensating clamp holder for the canvas comprises a fixed clamping board and a movable clamping board, and the movable clamping board and the fixed clamping board are movably connected with each other through a hinge device and an elastic device corresponding to the hinge device. The compensating clamp holder for the canvas ischaracterized in that a corresponding gripping device is arranged between the movable clamping board and the fixed clamping board. According to the compensating clamp holder for the canvas, the structure is simple, scientific and reasonable, the size and occupied area are small, clamping force is extremely compensating, clamping is firm, stable and reliable, and use operation is extremely simple and convenient.

Description

technical field [0001] The invention relates to a clamping device. In particular, it relates to a firm-clamped uniform canvas holder that can be used in industries such as advertisements. Background technique [0002] With the rapid development of the advertising media industry, the advertising hardware equipment and facilities are also developing accordingly, such as billboards, advertising light boxes, advertising windows, etc. that can be seen everywhere in urban and rural areas. With the continuous progress and development of technology, such The advertising device is constantly improving and innovating in terms of structure and function. Its rich content and shape variation make the advertising device not only a carrier of publicity, but also improve and add a prosperous environmental landscape. , but also give people a sense of beauty. [0003] Of course, the main function of advertising boxes, billboards, etc. is to promote advertisements. A good billboard advertisi...

AI Technical Summary

Problems solved by technology

Due to the unreasonable structure of this type of existing canvas clamping device, its elastic force is small, the clamping of the canvas is not firm, it often becomes loose, and it is not convenient enough to use

And in order to clamp firmly, the existing clamping device that has adopts to make each related parts thicker and increase the clamping area, which not only makes its clamping parts take up a large volume space in the advertisement box, wastes raw materials, but despite the development In this way, it is not only very inconvenient to use, but also difficult to open and clamp; in particular, due to its unreasonable structure, it is difficult for the corresponding flat plate to make the clamping wall absolutely parallel to the plane of the flat plate. In actual use, The larger the clamping surface of the clamping plate, the more likely it is that the clamping is not tight and the canvas is loose; in addition, when the corresponding part of the canvas or the wall of the clamping plate is adhered to dirt, protrusions, etc. , it is more prone to the problem of unstable and unstable canvas clamping

In addition, in order to clamp reliably and firmly, the use of increasing the number of canvas clamps can only be used to achieve the purpose of stable and firm clamping, which not only increases the production cost and use cost, but also increases the trouble in use and operation.
