[0002] Luggage refers to square containers used to carry various things, which can be made of wood, plastic, leather and other materials.

[0003] Luggage mainly consists of a lid and a body, wherein the body and lid are usually hinged via hinges to achieve rotational coordination between the lid and body. Since the hinges do not have a locking function (to position the lid after it is opened), the lid needs to be positioned by hand or against other objects (such as walls or cabinets) after it is opened. When subjected to external force, it may fall back and cause injuries to the user.

[0004] It can be seen that traditional luggage has certain safety hazards when in use, and how to prevent the lid from falling back after opening is worth studying. Utility Model Content

[0029] Example

[0030] Please refer to Figure 1-Figure 5 A hinge for preventing falling back includes a first leaf 1 and a second leaf 5 arranged below the first leaf 1. The first leaf 1 can rotate vertically relative to the second leaf 5 to adapt to the rotation of the box cover relative to the box body; a plurality of mounting seats 8 are arranged on the first leaf 1 and the second leaf 5, and any mounting seat 8 is provided with a mounting hole 7, so that the first leaf 1 and the second leaf 5 are connected to the box cover and the box body respectively. In actual design, the mounting hole 7 can be a threaded hole, so that the first leaf 1 and the box cover are connected by screws, and the second leaf 5 and the box body are connected by screws.

[0031] A U-shaped elastic member 6 is provided on one side where the second leaf 5 and the box body meet, and a gap is ensured between the U-shaped elastic member 6 and the box body to accommodate the deformation of the U-shaped elastic member 6. The inner sides of the two vertical portions of the U-shaped elastic member 6 are both provided with arc-shaped limiting portions 10, and the two arc-shaped limiting portions 10 are symmetrically arranged about the middle portion of the U-shaped elastic member 6.

[0032] The second leaf 5 is slidably provided with an adjusting member 3 on one side where the second leaf 5 and the box body meet, and the adjusting member 3 passes through the inner cavity of the U-shaped elastic member 6, and the diameter of the adjusting member 3 is greater than the distance between the two arc-shaped limiting portions 10, and the adjusting member 3 is preferably a rod structure;

[0033] The first leaf piece 1 is rotatably connected to the support member 2 , and one end of the support member 2 away from the first leaf piece 1 is rotatably connected to the adjusting member 3 .

[0034] In the present application, the first leaf 1 and the second leaf 5 are positioned on the box cover and the box body, respectively. When the first leaf 1 and the second leaf 5 are in the same plane, the box cover is closed on the box body, and the support member 2 is located above the two arc-shaped limiting portions 10. When the box cover needs to be opened, the first leaf 1 rotates relative to the second leaf 5, and the first leaf 1 makes the adjusting member 3 slide inside the U-shaped elastic member 6 through the transmission effect of the support member 2 until the adjusting member 3 passes through the two arc-shaped limiting portions 10 and stops (when the adjusting member 3 passes through the two arc-shaped limiting portions 10, the adjusting member 3 squeezes the two vertical parts of the U-shaped elastic member 6 to expand outward, so that the spacing between the two arc-shaped limiting portions 10 is increased for the adjusting member 3 to pass through), and the box cover is in an open state; if the box cover is to fall back, the two arc-shaped limiting portions 10 form a card position for the support member 2, and the support member 2 has a limiting effect on the first leaf 1, thereby preventing the first leaf 1 from falling back and improving the safety of the box body when in use.

[0035] At the same time, the U-shaped elastic member 6 has two arc-shaped limiting portions 10 for limiting the adjusting member 3, so that the first leaf piece 1 has a better anti-falling effect.

[0036] In some embodiments of the present invention, the second leaf 5 is provided with a mounting groove, and the U-shaped elastic member 6 and the adjusting member 3 are both arranged in the mounting groove.

[0037] In the above embodiment, the mounting groove provides mounting space for the U-shaped elastic member 6 and the adjusting member 3, and the depth of the groove is greater than the outer spacing value of the outer sides of the two vertical parts of the U-shaped elastic member 6, so that the U-shaped elastic member 6 can be deformed under force in the mounting groove, so that the adjusting member 3 can reciprocate through the locking structure formed by the two arc-shaped limiting parts 10.

[0038] In some embodiments of the utility model, guide grooves 4 are provided on both sides of the installation groove, any of the guide grooves 4 passes through the outer side of the second leaf 5, and both ends of the adjustment member 3 are slidably matched with the two guide grooves 4 respectively.

[0039] In the above embodiment, the sliding cooperation between the guide slot 4 and the adjusting member 3 improves the sliding stability of the adjusting member 3 on the mounting slot, so that the supporting member 2 drives the adjusting member 3 to slide in the U-shaped elastic member 6 more stably.

[0040] In some embodiments of the present invention, the support member 2 is disposed on a side of the second leaf sheet 5 away from the mounting groove, and the support member 2 is covered at a connection between the first leaf sheet 1 and the second leaf sheet 5;

[0041] Two ends of the adjusting member 3 respectively pass through the two guide slots 4 and are rotatably connected to the supporting member 2 on the same side.

[0042] In the above embodiment, the support member 2 is a shell structure, which can be covered at the connection between the first leaf 1 and the second leaf 5, that is, the support member 2 can not only support the first leaf 1 after rotation, but also protect the connection between the first leaf 1 and the second leaf 5.

[0043] It is also worth mentioning that the support member 2 is arranged to cover the connection between the first sheet 1 and the second sheet 5, which not only prevents the connection between the first sheet 1 and the second sheet 5 from absorbing dust, but also has the function of beautifying the appearance.

[0044] In some embodiments of the present invention, the support member 2 and the first leaf 1 are rotatably connected via a rotating shaft 9 .

[0045] In the above embodiment, the rotating shaft 9 can realize the rotational connection between the support member 2 and the first leaf 1, and both ends of the rotating shaft 9 are connected to the support member 2, which can improve the structural stability of the support member 2.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
