[0028] Closure assembly 400; torsion spring 410; pulley 420; first pin 430. Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] Hinges, such as Figure 1-6 As shown, it includes: a housing 100, a head 200, a conductive assembly 300, and a closing assembly 400. The head 200 is rotatably mounted on one end of the housing 100, and the head 200 is connected to the conductive assembly 300. The conductive assembly 300 includes: an inner support 310 and a spring 320; the end of the inner support 310 is rotatably connected to the head 200.

[0031] The closing assembly 400 includes: a torsion spring 410 and a pulley 420;

[0032] The pulley 420 can move along the end face 201 of the head 200, and when the head 200 swings relative to the outer shell 100 to the closed position, the pulley 420 is pressed against the end face 201 by the elastic force of the torsion spring 410, so that the head 200 is kept in the closed position.

[0033] When the head 200 swings relative to the outer casing 100 to the open position, the pulley 420 leaves the end face 201.

[0034] Specifically, the outer shell 100 is made of high-hardness metal and is in a semi-open state; the head 200 is rotatably mounted to one end of the outer shell 100 by means of a pin and a flower wheel, and the head 200 is also made of high-hardness metal.

[0035] The inner support 310 has a symmetrically arranged left support plate and a right support plate, which are connected and installed inside the outer shell 100 and connected to the head 200.

[0036] During assembly, the opening of the inner bracket 310 is limited in the second slot 120 of the outer shell 100 by the second pin 330; one end of the spring 320 is fixed to the outer shell 100, and the other end is fixed to the second pin 330.

[0037] Therefore, during the swinging of the head 200, the inner support 310 is pulled to move within the outer shell 100, which in turn pulls the spring 320 to deform and generate elastic force.

[0038] Furthermore, after the torsion spring 410 is assembled into the housing 100, the torsion spring 410 has a preload, which is applied to the head 200 through the pulley 420.

[0039] The pulley 420 is mounted to the torsion spring 410 via the first pin 430;

[0040] Specifically, of the two ends of the torsion spring 410, one end is limited to the outer shell 100, and the other end is connected to the pulley 420. The outer shell 100 is provided with a first strip groove 110. The first pin 430 passes through the first strip groove 110. The middle part of the torsion spring 410 can be limited inside the outer shell 100 by the pin. The deformed part of the torsion spring 410 locally presses against the outer shell 100, so that the torsion spring 410 has a preload.

[0041] During the swinging process of the head 200, the torsion spring 410 is pushed, causing the torsion spring 410 to deform further.

[0042] Furthermore, the inner support 310 is provided with a track groove 311, which is arc-shaped; when the head 200 swings to the open position, the first pin 430 moves to the end of the track groove 311 and is limited.

[0043] Furthermore, the head 200 is equipped with a latch 210, which is used to assist the hinge in being installed in a small household appliance.

[0044] The specific use of this utility model is further explained below:

[0045] like Figure 5 As shown, in the closed state, the pulley 420 is pressed against the end face 201 of the head 200 by the elastic force of the torsion spring 410, so that the head 200 is better kept in the closed state;

[0046] When the head 200 is rotated counterclockwise, the pulley 420 moves along the end face 201 during the rotation. The end face 201 is a curved surface. As the radius of the curved surface changes, the pulley 420 is pushed to the left in the first groove 110. When the torsion spring 410 is further deformed, the pulley 420 is pressed against the end face 201.

[0047] At the same time, the head 200 pulls the inner support 310 to the left, the spring 320 deforms and provides a pulling force to the right, causing the head 200 to slowly open, as if... Figure 6 As shown, at this time, pulley 420 is away from end face 201, and torsion spring 410 has preload.

[0048] Additionally, when the head 200 from Figure 6 As shown, when rotated clockwise, spring 320 provides tension to close head 200. When head 200 rotates to the point where end face 201 re-contacts pulley 420, pulley 420 provides resistance to closing head 200, causing head 200 to close slowly. After closing, as shown... Figure 5 As shown, at this time, pulley 420 is pressed against end face 201.

[0049] This utility model hinge adds a closing component 400 to the transmission component 300. The closing force in the closed state is coordinated with the pulley 420 through the change of the curve of the end face 201 of the head 200. The magnitude and occurrence time of the closing force change with the change of the curve of the end face 201, and the torque of the torsion spring 410 changes accordingly. The overall structure is compact and the assembly is simple.
