[0048] like Figures 1 to 12 A specific embodiment of the hinge structure shown is suitable for rotatably connecting the upper cover 2 and the bottom shell 3 constituting the box body. The hinge structure includes: an inner hinge assembly 10, an outer hinge assembly 20, a pin shaft 30 and an elastic member.
[0049] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, a first limiting portion 100 is convexly provided on the surface of the inner hinge assembly 10; a first rotating cylinder 101 is provided on the side of the inner hinge assembly 10. A second limiting portion 200 is convexly provided on the surface of the outer hinge assembly 20; a second rotating cylinder 201 is provided on the side of the outer hinge assembly 20. The pin shaft 30 is inserted into the first rotating cylinder 101 and the second rotating cylinder 201. When the inner hinge assembly 10 and the outer hinge assembly 20 are relatively rotated around the pin shaft 30 until the first limiting portion 100 abuts against the second limiting portion 200, the angle formed between the inner hinge assembly 10 and the outer hinge assembly 20 is less than 90°.
[0050] Preferably, the abutment between the first limiting portion 100 and the second limiting portion 200 is in plane contact, and the first limiting portion 100 is directly opposite to the second limiting portion 200; that is, the first limiting plane 1001 on the first limiting portion 100 is in contact with the second limiting plane 2001 on the second limiting portion 200. Figure 4As shown, when the first limiting portion 100 abuts against the second limiting portion 200, the angle formed between the inner hinge assembly 10 and the outer hinge assembly 20 is a, 60°<a<90°, and correspondingly, the angle b formed between the upper cover 2 and the bottom shell 3 ranges from 90° to 120°. Preferably, the angle a is 85°, and correspondingly, the angle b is 95°. The first limiting plane 1001 is an inclined plane; the second limiting plane 2001 is an inclined plane.
[0051] like Figure 8 As shown, the inner hinge assembly 10 includes: a first hinge piece 102 and a first connecting piece 103. The first rotating cylinder 101 is arranged on the first hinge piece 102; the first connecting piece 103 connects the first hinge piece 102 and the first limiting portion 100. Two symmetrical first rotating cylinders 101 are arranged on the inner hinge assembly 10; two symmetrical first rotating cylinders 101 are arranged on the inner hinge assembly 10. Specifically, the first connecting piece 103 is welded to the first hinge piece 102, and the first connecting piece 103 is integrally arranged with the first limiting portion 100; the first limiting portion 100 is located between the two first rotating cylinders 101.
[0052] like Fig.11 As shown, the outer hinge assembly 20 includes: a second hinge piece 202 and a second connecting piece 203. The second rotating cylinder 201 is arranged on the second hinge piece 202; the second connecting piece 203 connects the second hinge piece 202 and the second limiting portion 200. Two symmetrical second rotating cylinders 201 are arranged on the outer hinge assembly 20. Specifically, the second connecting piece 203 is welded to the second hinge piece 202, and the second connecting piece 203 is integrally arranged with the second limiting portion 200. Figure 5 and Figure 6 As shown, the positions of the two second rotating drums 201 on the pin shaft 30 are respectively located outside the two first rotating drums 101 ; the second limiting portion 200 is located between the two second rotating drums 201 .
[0053] like Figure 7 As shown, one end of the elastic member is connected to the inner hinge assembly 10, and the other end of the elastic member is connected to the outer hinge assembly 20; when the inner hinge assembly 10 and the outer hinge assembly 20 rotate around the pin shaft 30, the elastic member is used to provide an elastic force to make the first limiting portion 100 close to the second limiting portion 200.
[0054] It is understandable that, in reality, a stove can be placed in the box. When the upper cover 2 is closed on the stove, if the box is not held firmly, the upper cover 2 may easily collide directly with the bottom shell 3. Therefore, the present application provides an elastic member in the hinge structure 1 of the box to cushion the collision between the upper cover 2 and the bottom shell 3.
[0055] Preferably, combined Fig.10 and Fig.12 As shown, the elastic member is a torsion spring 40; the torsion spring 40 is sleeved on the pin 30; the two ends of the torsion spring 40 are respectively provided with a first leg 400 and a second leg 401; the first leg 400 extends into the first groove 1000 provided in the first limiting portion 100, and the second leg 401 extends into the second groove 2000 provided in the second limiting portion 200. The angle c between the first leg 400 and the second leg 401 can be 10°. The first groove 1000 is surrounded by the first limiting portion 100 and the first hinge piece 102; the second groove 2000 is surrounded by the second limiting portion 200 and the second hinge piece 202.
[0056] like Figures 1 to 4 As shown, the utility model further provides a box body, comprising: an upper cover 2 and a bottom shell 3 that are rotatably connected, and the hinge structure 1. The hinge structure 1 connects the upper cover 2 and the bottom shell 3. The hinge structures 1 are two arranged at intervals. Obviously, the above embodiments are only examples for clear description, and are not limitations on the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the protection scope of the invention of the utility model.
