Fixing part connected with photo frame backboard and manufacturing method of fixing part

Abstract

The invention provides a fixing part connected with a photo frame backboard. The fixing part comprises a rotating portion and a fixed portion connected with a photo frame, one end of the rotating portion is connected with the fixed portion, the other end of the rotating portion is connected with a fixing substrate for fixing the photo frame, and a concave rotating surface and a convex rotating surface are connected in an embedded manner to form the rotating portion. The invention further provides a method for manufacturing the fixing part connected with the photo frame backboard. The fixing part is simple and reasonable in structure, high in mechanization degree, convenient to use, fine in mounting consistency and high in production efficiency, and can be effectively and firmly connected and can flexibly rotate.

Description

technical field [0001] The invention relates to the production technology of the photo frame, in particular to a fixing part used for connecting with the back plate of the photo frame and a manufacturing method thereof. Background technique [0002] A photo frame is a product used to place photos for viewing in daily life. It is usually placed on a horizontal surface (such as a desktop) or hung on a vertical surface (such as a wall), and is usually connected to the back of the photo frame. There are fixing parts to realize the aforementioned usage, such as setting a support frame to horizontally support and fix the photo frame, or connecting a pendant so that the photo frame can be hung on the raised part of the vertical surface through the pendant; the fixing part often needs to be connected to the backboard Meet certain requirements: 1. While firmly connected to the backplane, it can be rotated conveniently and flexibly according to the use status, so as to be properly ins...

AI Technical Summary

Problems solved by technology

The existing fixing parts are generally connected to the backboard by screw connection or rivet fixing. In the form of screw connection, the screw is directly passed through the fixing part and then screwed into the backboard (such as figure 1 shown), this method is simple in structure and easy to operate, but it is difficult to meet the requirements of firm connection and flexible rotation at the same time. If the screw is tightened, it will be difficult to rotate the fixed part, but if it is not tightened, it will be easier. loose, and this method is difficult to achieve the consistency of the connection of each fastener, which cannot meet the requirements of standardization; the connection method fixed by rivets such as figure 2 As shown, the specific method is to first open a hole on the back plate, then pass the rivet through the hole on the fixing part and the opening on the back plate by hand, and then flang the rivet on the other side of the back plate to realize the connection between the fixing part and the back plate. The riveting of the board, this connection method has better connection stability and is more difficult to fall off, but it also has obvious disadvantages: because it is necessary to open a hole on the back board first, after opening the hole, it is necessary to manually pass the rivet through the fixing part and the back board , and then flanging and fixing, so the operation steps are more cumbersome, the labor intensity is high, and the production efficiency is low; and it is also difficult to achieve the consistency of the connection tightness of each fixing part (if the connection is tight, the rotation will be affected); so the existing There are different degrees of shortcomings in the connection methods of fixing parts, which cannot meet the requirements of large-scale and high-quality production
