Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a lift lid electrical apparatus hinge structure which characterized in that: the electric appliance comprises an electric appliance main machine 1 and a lifting cover 2, wherein the electric appliance main machine 1 is hinged with the lifting cover 2 through a hinge, so that the lifting cover 2 is opened in an upturning mode; the hinge comprises a hinge main body 3 and a hinge arm 4, wherein a hinge hole 5 is formed in the hinge arm 4 and is hinged to the hinge main body 3 through a first hinge shaft 6, the front end of the hinge arm 4 is fixed to the electrical appliance main body 1 or the flip cover 2, the tail of the hinge arm 4 is hinged to a pull arm 7 through a second hinge shaft 61, the tail of the pull arm 7 is connected with the hinge main body 3 through a tension spring 8, and the tension spring 8 pulls the hinge arm 4 backwards all the time through the pull arm 7, so that the front end of the hinge arm 4 is tilted, and the hinge is always in an open state; the hinge is characterized in that a guide wheel frame 9 is further arranged in the hinge main body 3, the tail part of the guide wheel frame 9 is slidably installed in a guide hole 10, a guide wheel 11 is installed at the front end of the guide wheel frame 9, a push spring 12 is sleeved on the surface of the guide frame, and the push spring 12 pushes the guide wheel to move towards the hinge arm all the time.
The first hinge shaft 6 is located at the front end of the second hinge shaft 61.
The guiding surface 13 is a self-locking surface 131 and a reset surface 132 arranged on the outer contour of the hinge arm 4, the reset surface 132 pushes the guiding hole 10 to compress the push spring 12 to generate a direction towards the hinge arm in the process that the hinge arm 4 rotates around the hinge hole 5, and when the self-locking surface 131 rotates to the guiding hole 10, the push spring 12 pushes the guiding hole 10 to slide towards the self-locking surface 131, so that the cover 2 is automatically closed.
The guide wheel 11 is slidably mounted in a guide slot 15 of the hinge body 3 through a guide post 14.
The hinge body 3 is fixed on the electrical apparatus main machine 1, and the hinge arm 4 is fixed on the lifting cover 2.
The hinge body 3 is fixed on the flip cover 2, and the hinge arm 4 is fixed on the electrical apparatus main machine 1.
The electric appliance is an air fryer, a dish washer, a refrigerator, an electric cooker, a pressure cooker, a stew pot and a bread maker.
The working principle is as follows: compared with a single hinge structure in the prior art, the hinge has larger bearing capacity, so that the hinge is suitable for large or heavy cover-lifting electric appliances, such as air fryer, dish washer, refrigerator, electric cooker, pressure cooker, stew pot, bread maker and the like.
When the lifting cover needs to be opened by a user, the lifting cover drives the hinge arm to move, the hinge arm rotates by taking the hinge shaft as a circle center, the pull arm and the tension spring which are positioned at the tail part of the hinge arm have certain tension force while the hinge arm rotates, the hinge is forced to move towards the opening direction, therefore, the tension force of the tension spring is greater than the gravity of the lifting cover, when the lifting cover is opened to a set angle, the tension spring pulls the hinge arm to be automatically opened to a full-open state, and the opening state of the lifting cover is kept, so that the operation of the user is facilitated.
The tension spring 8 plays a role in damping the hinge closing process, balances the cover lifting gravity and the pressure of the push spring 12, enables the cover lifting to stop at any angle after the cover lifting is released by a user, and when the cover lifting is required to be closed by the user, the cover lifting is pulled downwards to drive the hinge arm to be closed, and when the hinge arm is closed, the pressure applied to the cover lifting by the user and the gravity of the cover lifting force the hinge and the cover lifting to be closed. When the hinge arm is closed to a certain included angle (the degree of the included angle can be freely designed), the guide surface on the outer contour of the hinge arm and the guide wheel are mutually extruded to realize automatic closing of the flip cover, and after the hinge and the flip cover are completely closed, the guide wheel enters the inwards concave self-locking surface 131, so that the hinge arm is locked, and the sealing effect on the flip cover is realized.
Compared with the prior art, the hinge in the present case has greater supporting force, thereby the large or heavy commercial electric cooker, pressure cooker, stew pan, bread maker and other equipment can be used, meanwhile, the hinge has the function of stopping at any angle, the lifting cover can stay at any angle after being opened, thereby the traditional lifting cover hinge is prevented from being in two states of opening or closing, the operation of a user is facilitated, and the hinge can be widely popularized and used.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
