Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of folding box, especially a top cover sliding connection mechanism of folding box. BACKGROUND

[0002] In the prior art, folding boxes are used to place articles, and generally have a top cover. The top cover is hinged to the side plate of the front face of the box body in the form of a hinge, so that the folding is achieved, and the folding of the box body is not affected.

[0003] Of course, there are also connection forms using sliding rails, such as the Chinese utility model patent 202020648352.9, a sliding type flip cover structure and a folding storage box, which uses a curved connecting piece to set the inner surface of the side plate of the front face of the box body. Since the top of the side plate of the front face of the box body is inwardly bent, the setting of the connecting piece inevitably causes the bent part of the side plate of the front face of the box body to form a gap, so that the bent part can be rotated outward. This will greatly affect the strength of the top of the side plate of the front face of the box body, and the performance is relatively poor. SUMMARY

[0004] The utility model discloses a top cover sliding connection mechanism of folding box to solve the above technical deficiency, which realizes the flip connection of the top cover and the side plate of the front face of the box body, and has high overall connection strength.

[0005] The utility model discloses a top cover sliding connection mechanism of folding box, including box body and top cover, the top of the side plate of the front face of the box body is provided with recessed step at both ends, the recessed step is provided with swing arm, the swing arm one end with recessed step between through pin shaft rotation connection, swing arm the other end portion is provided with the sliding part that protrudes outward, the lower surface of top cover is provided with the sliding groove, the sliding groove with swing arm corresponds, the sliding part sets up in the sliding groove, and sliding connection is established between the sliding part and the sliding groove.

[0006] The sliding groove is L-shaped or T-shaped, and the sliding part is formed on one side or both sides of the end of the swing arm.

[0007] The sliding part is a cylindrical structure.

[0008] The side wall of the top cover is downwardly folded, and an L-shaped blocking strip is arranged along the side wall of the top cover. The L-shaped blocking strip and the side wall have a gap, and the gap forms the sliding groove.

[0009] The top cover sliding connection mechanism of the folding box obtained by the utility model is provided with recessed steps at both ends of the top of the side plate of the front face of the box body, and the sliding connection of the swing arm and the sliding part at the end of the swing arm with the sliding groove inside the top cover is achieved through cooperation, so that the overall connection strength is high, and the sliding process is more stable and reliable.

[0017] In order to further illustrate the technical means and effects taken by the utility model to achieve the predetermined utility model purposes, the following will combine the drawings and the preferred embodiments to specifically explain the specific implementation, structure, features and effects of the utility model, which are described as follows.

[0018] Example 1:

[0019] As Figures 1-7 shown, the utility model discloses a kind of top cover sliding connection mechanism of folding box, including box 1 and top cover 2, in the top of the front side plate 8 of box 1, two ends are provided with inner recessed step 7, inner recessed step 7 is provided with swing arm 4, one end of swing arm 4 is connected by pin shaft rotation between inner recessed step 7, outer protruding sliding portion 5 is provided in the other end of swing arm 4, sliding groove 6 is provided in the lower surface of top cover 2, the sliding groove 6 corresponds with swing arm 4, the sliding portion 5 is set in sliding groove 6, sliding connection between sliding portion 5 and sliding groove 6.

[0020] The inner recessed steps 7 are arranged at the top of the front side plate 8 of the box body 1, and the top of the front side plate 8 of the box body 1 is folded upward, so that the inner recessed steps 7 are formed at the folded position, and the whole folded position is continuous. The inner recessed steps 7 are arranged at the two ends of the top of the front side plate 8 of the box body 1, and are located at the intersection of the side edge folding and the top folding of the side plate 8. The strength of the intersection is large, and the strength of the side plate 8 is not affected. The swing arm 4 is connected by a pin shaft, so that the swing arm 4 can rotate around the pin shaft. During the swinging process of the swing arm 4, the end of the swing arm 4 can swing to the inner side of the front side plate 8 of the box body 1, or to the outer side of the front side plate 8 of the box body 1. That is, the length of the swing arm 4 needs to be greater than the distance between the pin shaft and the inner side and the outer side of the front side plate 8 of the box body 1. In this way, it can be ensured that the top cover 2 can smoothly cover the box body 1 and be turned over to the outer surface of the front side plate 8 of the box body 1. When the top cover 2 is opened, the swing arm 4 is limited by the step when it swings to the outer end, and the swing arm 4 remains in a substantially horizontal state. The sliding part 5 at the end of the swing arm 4 cooperates with the sliding groove 6 on the inner side of the top cover 2. When the sliding part 5 slides to the end of the sliding groove 6, the top cover 2 is hung on the swing arm 4, and the overall connection is firm and stable.

[0021] The sliding groove 6 is L-shaped or T-shaped, and the sliding part 5 is protruded on one side or both sides of the end of the swing arm 4. Since the inner recessed steps 7 are arranged at the top of the front side plate 8 of the box body 1, the swing arm 4 is as close to the side edge as possible. Therefore, the sliding groove 6 of the preferred embodiment is L-shaped, and the sliding part 5 on the swing arm 4 is located on the inner side of the swing arm 4, that is, the sliding part 5 is closer to the inner side of the box body 1 relative to the swing arm 4.

[0022] The end of the swing arm 4 and the sliding part 5 form an L-shaped structure, and are located inside the sliding groove 6. In this way, the stability of the swing arm 4 and the sliding part 5 in the sliding groove 6 is higher.

[0023] The sliding part 5 is a cylindrical structure. During the turning process of the top cover 2, the swing arm 4 and the sliding part 5 are also rotating relative to the top cover 2. Therefore, the sliding part 5 is a cylindrical structure, which makes the turning process in the sliding groove 6 more smooth. The contact area between the sliding part 5 and the sliding groove 6 is small during the sliding process of the sliding part 5 in the sliding groove 6, so the friction of the sliding is small, the resistance of the top cover 2 during the turning process is small, and the opening and closing of the top cover 2 is more smooth and stable.

[0024] The side wall 9 of the top cover 2 is folded downward, and an L-shaped blocking strip 3 is arranged along the side wall 9 of the top cover 2. There is a gap between the L-shaped blocking strip 3 and the side wall 9, and the gap forms the sliding groove 6.

[0025] Since the side wall 9 of the top cover 2 is folded downward, the L-shaped blocking strip 3 is arranged along the side wall 9 on the inner side of the top cover 2, and an L-shaped gap is formed between the L-shaped blocking strip 3 and the side wall 9 of the top cover 2, which is the sliding groove 6. The swing arm 4 and the sliding part 5 are arranged in the sliding groove 6 of the L-shaped gap, which is firm and stable, and can connect the top cover 2. The end of the swing arm 4 and the sliding groove 6 are in contact with two sides, so the stability is high, and the top cover 2 is not easy to swing during sliding, so the sliding process is more smooth and reliable.

[0026] The L-shaped blocking strip 3 can be fixedly connected with the top cover 2 through a screw, which is convenient to disassemble.

[0027] The sliding groove 6 is formed by the L-shaped blocking strip 3 and the side wall 9 of the top cover 2, which can effectively reduce the cost and save materials.
