Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a hinge which can be automatically reset. Background Art

[0002] In the existing technology, in order to facilitate the automatic closing of the door, the door cannot stay at a specific position when it is opened. When a person releases the door, the door automatically closes. When there are many people entering or leaving or moving goods, the person needs to push the door panel manually in real time to stop the door panel at a specific position, which is inconvenient for people to enter or leave and for moving goods.

[0003] Moreover, as disclosed on January 24, 2007, the Chinese utility model patent with the authorization announcement number CN2861423Y discloses a one-piece reset multifunctional hinge, which records that the automatic reset rotation is realized by two opposite inclined surfaces of the upper lifter and the lower lifter, and the upper lifter is fixedly connected to the middle sleeve. The lower lifter is fixedly connected to the lower sleeve, so when the upper lifter and the lower lifter rotate relative to each other and move up and down axially, the door body also rotates and moves up and down together; that is, the hinge realizes the automatic resetting rotation of the door leaf under the action of the gravity of the door leaf itself, so the inclination angle of the inclined plane is required to be large, and the force used by people when pushing the door is large, that is, the hinge will make the door leaf very heavy and difficult to push when in use; when the door leaf rotates to a certain angle so that the concave-convex groove on the upper lifter and the concave-convex groove on the lower lifter are engaged with each other, a large force is required to engage the concave-convex groove on the upper lifter and the concave-convex groove on the lower lifter, and when the door needs to leave a specific stop position, a large force is also required to first disengage the concave-convex groove on the upper lifter from the engaged state, so that the door leaf can automatically reset, which is laborious and inconvenient to use. For this reason, an automatically reset hinge is proposed, which is convenient for people to enter and exit or move goods and can automatically reset the door. Summary of the invention

[0004] The purpose of the utility model is to solve the above problems and to provide an automatically reset hinge.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatically resettable hinge, comprising a hinge frame and a hinge sheet body rotatably mounted on the hinge frame; the hinge frame and the hinge sheet body are respectively provided with a hinge frame shaft sleeve and a hinge sheet body shaft sleeve; its characteristic is that an upper rotating seat with a plurality of toothed bosses is movably mounted in the hinge sheet body shaft sleeve; a limit block for limiting the position of the hinge sheet body is mounted on the upper rotating seat; and a torsion spring is also connected to the upper rotating shaft for facilitating the automatic reset of the hinge sheet body.

[0006] Preferably, the limit block is also provided with a toothed boss adapted to the toothed boss on the upper rotating seat.

[0007] Preferably, guiding inclined surfaces and limiting surfaces are provided on the toothed bosses.
