Description

TECHNICAL FIELD

[0001] The utility model relates to a travel case technical field, especially a travel case nailless frame and quick assembly structure. BACKGROUND

[0002] In the currently commonly used travel case, a set of frame with concave-convex fitting is arranged on the opening edge of the front and rear case shell, which aims to increase the use strength of the travel case and improve the closure matching degree and tightness of the two case shells, facilitating user use.

[0003] The prior art is rivet fixed by rivet, and the frame after bending is fixed on the opening of the case shell by rivet. The fixing method is simple in principle, and is most widely used in the industry at present. However, it is inconvenient to operate and the production efficiency is low in actual production and use. In addition, the rivet needs a via hole for riveting, and multiple via hole fixing points must be provided, resulting in more steps for binding and more pre-processes. When the overlapping hole is provided at the splicing overlapping position, misalignment often occurs and needs to be corrected manually, which is not easy to operate. In addition, the operator needs to hold the box body to operate the rivet machine, and when the size of the box body is large, the operation convenience is very low, the worker is easily tired, and the production efficiency and safety are affected. Because the number of rivets is large, the production efficiency is low, and the production cost of the product is increased.

[0004] The structure between the two rivets is weak and prone to gaps. Even if the rivets are arranged densely, there will always be a certain gap between adjacent rivets. This gap is not completely fixed, the structure strength is low, and the overall fixing strength is not ideal. When local collision deformation occurs, the frame and the case shell are easily separated to form a gap, which affects the appearance and brings a bad product experience to the user.

[0005] The exposed rivets affect the appearance of the travel case. The rivets are exposed on the outside of the frame, and the number is large, which affects the overall appearance of the travel case. UTILITY MODEL CONTENT

At the same time, the top snap-fit ​​part 35 of the first frame is pushed upward by the opening 13 of the first box shell, and the first box shell clip 14 is compressed upward by the right side protrusion 38 of the first frame, causing the first box shell clip 14 to undergo slight deformation. After the opening 13 of the first box shell and the first box shell clip 14 pass through the right side entrance of the first frame snap-fit ​​assembly groove 36 in sequence, the bent part 12 of the first box shell abuts against the right side of the top snap-fit ​​part 35 of the first frame, and the first box shell clip 14 abuts against the inner side of the inverted part 37 of the first frame, forming a mutually snapped state. At this time, the first box shell 1 is snapped and fixed in the first frame snap-fit ​​assembly groove 36 and cannot be removed.

[0129] Similarly, insert the second housing 2 into the second frame 4 in the direction of the arrow to the right. Slight force needs to be applied to the second frame 4. The opening 23 of the second housing first moves along the left rib 48 of the second frame towards the snap-fit ​​assembly groove 46 of the second frame. At the same time, the top snap-fit ​​part 45 of the second frame is pushed upward by the opening 23 of the second housing, and the snap-fit ​​strip 24 of the second housing is compressed upward by the left rib 48 of the second frame, causing the snap-fit ​​strip 24 of the second housing to deform slightly. After the opening 23 of the second housing and the snap-fit ​​strip 24 of the second housing pass through the left entrance of the snap-fit ​​assembly groove 46 of the second frame in sequence, the bent part 22 of the second housing abuts against the left side of the top snap-fit ​​part 45 of the second frame, and the snap-fit ​​strip 24 abuts against the inner side of the undercut part 47 of the second frame, forming a snap-fit ​​state. At this time, the second housing 2 is snapped and fixed in the snap-fit ​​assembly groove 46 of the second frame and cannot be removed.

[0130] The second working principle:

[0131] like Figure 11 As shown, taking the first box shell 1 and the first frame 3 as an example, the first box shell 1 is inserted into the first frame 3 in the direction of the arrow to the left. The first frame 3 needs to be slightly forceful. The opening 13 of the first box shell first moves along the right side protrusion 38 of the first frame to the first frame snap-fit ​​assembly groove 36. At the same time, the top snap-fit ​​part 35 of the first frame is pushed upward by the opening 13 of the first box shell, and the first box shell buckle 16 is compressed upward by the right side protrusion 38 of the first frame, causing the first box shell buckle 16 to undergo slight deformation. After the opening 13 of the first box shell and the first box shell buckle 16 pass through the right side entrance of the first frame snap-fit ​​assembly groove 36 in sequence, the bent part 12 of the first box shell abuts against the right side of the top snap-fit ​​part 35 of the first frame, and the first box shell buckle 16 abuts against the inner side of the inverted part 37 of the first frame, forming a mutually snapped state. At this time, the first box shell 1 is snapped and fixed in the first frame snap-fit ​​assembly groove 36 and cannot be removed.

[0132] Similarly, insert the second housing 2 into the second frame 4 in the direction of the arrow to the right. Slight force needs to be applied to the second frame 4. The opening 23 of the second housing first moves along the left rib 48 of the second frame towards the snap-fit ​​assembly groove 46 of the second frame. At the same time, the top snap-fit ​​part 45 of the second frame is pushed upward by the opening 23 of the second housing, and the buckle 26 of the second housing is compressed upward by the left rib 48 of the second frame, causing the buckle 26 of the second housing to deform slightly. After the opening 23 of the second housing and the buckle 26 of the second housing pass through the left entrance of the snap-fit ​​assembly groove 46 of the second frame in sequence, the bent part 22 of the second housing abuts against the left side of the top snap-fit ​​part 45 of the second frame, and the buckle 26 of the second housing abuts against the inner side of the inverted part 47 of the second frame, forming a snap-fit ​​state. At this time, the second housing 2 is snapped and fixed in the snap-fit ​​assembly groove 46 of the second frame and cannot be removed.
