Face frame opening structure of indicating device

Abstract

The invention relates to a face frame starting structure of marking device, which comprises a main frame (10) and a face frame (20), wherein at least one side in the front and back of upside of the main frame (10) extends outwards a horizontal extending section (11) and bends upwards into a circular arc hook (12). The inner side on the upside of the face frame (20) is provided with a concave circular arc pillar face (21). The intersection on the top border of the concave circular arc pillar face (21) and the face frame (20) is formed downwards into a hanging hook (22). The invention further comprises a positioning plate (30) which can be detachably fixed on the inner side of the face frame (20). The circular arc hook (12) is assembled on the inner side of the hanging hook (22). A concave circular arc end face (31) of the positioning plate (30) is adhered on a convex circular arc pillar face (121) on the outside of the circular arc hook (12). In the process of open or close of the face frame (20), the concave circular arc pillar face (21) slides upwards or downwards along the outer side of the circular arc hook (12). The invention has the advantages of convenient manufacture and assembly, high producing efficiency, convenient changing the internal marking content by starting the face frame upward to 90 degrees and internal structure maintenance and so on.

Description

technical field [0001] The present invention relates to a labeling device with replaceable internal labeling content, in particular to a surface frame opening structure of the labeling device. Background technique [0002] At present, marking devices for marking or advertising are more and more widely used, and there are various large-scale marking devices, such as large display windows, advertising boxes next to road stations, and various large-scale indication or advertising light boxes These marking devices generally include a main frame, a face frame, and marking content and illuminants in the device. In order to facilitate the replacement of the internal marking content or internal structure maintenance, the face frame is set in a manner that can be opened relative to the main frame. The surface frame and the main frame of the prior art marking device are generally connected from the top or the bottom by hinges or other hinges, so as to realize the opening of the surfac...

AI Technical Summary

Problems solved by technology

The surface frame and the main frame of the prior art marking device are generally connected from the top or the bottom by hinges or other hinges, so as to realize the opening of the surface frame. The defects of this method are: 1. Using hinges or other hinges , the cover between the surface frame and the main frame is not tight, especially when the width of the marking device is large, the more hinges are used, the poorer the matching accuracy between the surface frame and the main frame; Visual effect, and it is easy to rust when exposed to the sun and rain; 3. Assembly and assembly are difficult, laborious and time-consuming, and the production efficiency is low

In order to avoid the shortcomings of the above-mentioned marking device, the Chinese invention patent application with the publication number CN 1102726A discloses a hingeless shield for the marking device. The technical solution recorded in the patent application solves the above problems to a certain extent , but there are also the following deficiencies: First, due to the limitation of the depth of the edge of the groove and the thickness of the protruding part, the opening angle of the surface frame is very small, generally around 45 degrees, and the surface frame cannot be opened into a horizontal state, so It is not very convenient to replace the marked content or maintain the internal structure; secondly, the most serious defect of this invention application is that due to the limitation of the structural design and assembly method, the surface frame of the said marking device cannot be made into an integral structure in advance, and it must be assembled during assembly. Register from the end, so that the groove on the top frame fits into the cylindrical convex strip on the top main frame, and then the left, right and lower frames can be assembled with the top frame to form a complete frame body

This assembly method is quite inconvenient when the width of the marking device is large; moreover, in order to ensure the connection and combination accuracy of the various components during assembly, it is bound to increase the difficulty and cost of manufacturing and processing each component, and at the same time reduce the production efficiency. , Moreover, once the combination accuracy is not enough during assembly, it will lead to manufacturing rework, which is time-consuming and laborious
