AI Technical Summary
In the existing technology, during the production process of bags with frame connections, the existing frame materials are divided into plastic frames and metal frames. The connection methods for the existing frames require rivets for fixing, and the connection methods for the metal frames are difficult to improve processing efficiency and reduce processing costs.
The installation structure adopts a rivetless frame. By setting U-shaped grooves and U-shaped snap-fit parts on the frame and utilizing the snap-fit structure of elastic material, it solves the problems of low production efficiency and high cost in the existing frame connection methods, which require riveting or glue fixing for plastic and metal frames.
It achieves stable fixation without the need for riveting or gluing, thereby improving production efficiency and reducing production costs.

Abstract
Claims
1. A mounting structure of a rivetless frame box including a frame body (1) and a box shell (2), characterized by, The frame (1) is provided with a U-shaped groove (3), and both ends of the U-shaped groove (3) are provided with protruding locking platforms (5). A U-shaped locking member (4) is provided in the mounting groove, and the two ends of the U-shaped locking member (4) are respectively locked and engaged with the two locking platforms (5). The inner wall of the U-shaped locking member (4) is provided with a protruding elastic part (6), and the elastic part (6) is provided with a locking part (7). The part of the box shell (2) that extends into the U-shaped groove (3) is provided with a locking groove that matches the elastic locking part (7). The box shell (2) is gradually subjected to force and extends into the U-shaped locking member (4). The locking part (7) abuts against the surface of the box shell (2), causing the elastic part (6) to undergo elastic deformation and the locking part (7) to slide along the surface of the box shell (2). When the locking part (7) slides into the locking groove, the elastic part (6) resets and the locking part (7) engages with the locking groove.
2. The rivetless frame box mounting structure according to claim 1, wherein The U-shaped snap fastener (4) is made of elastic metal material, and the U-shaped snap fastener (4) is bent inward at the position of the elastic snap fastener (7) to form the elastic part (6).
3. The rivetless frame box mounting structure according to claim 2, characterized by One of the elastic parts (6), one of the snap-fit parts (7) and one snap-fit groove form a snap-fit unit. There are two snap-fit units, which are located on both sides of the housing (2).
4. The rivetless frame box mounting structure according to any one of claims 1 to 3, characterized by, The snap-fit part (7) includes a conical ridge, and the slot is a V-shaped groove that is adapted to the shape of the ridge.
5. The rivetless frame box mounting structure according to claim 4, wherein The protruding ridge is inclined inward toward the U-shaped snap fastener (4).
6. The rivetless frame box mounting structure according to claim 1, wherein The housing (2) is provided with an abutment part (8). When the housing (2) is installed in the preset position inside the U-shaped snap fastener (4), the abutment part (8) and the corresponding position of the frame (1) abut against each other.
