Technical Field

[0001] The invention relates to the technical field of oven flap door damping hinges, in particular to a horizontal damping hinge for a steam oven flap door. Background Art

[0002] A damping hinge is a hydraulic buffer hinge that utilizes the buffering properties of liquid and has an ideal buffering effect. The door starts to close slowly at sixty degrees, reducing the impact force and forming a comfortable damping hinge effect when closing. Damping hinges are needed in the use of ovens, but existing damping hinges cannot close automatically when the flap is opened and closed widely, which increases the labor of manual closing and reduces the convenience of using the oven. Summary of the invention

[0003] In order to solve the problems raised in the above-mentioned background technology, the purpose of the present invention is to provide a horizontal damping hinge for the flap door of a steam oven, which has the advantage of auxiliary reset and solves the problem that the existing damping hinge does not have the function of auxiliary reset, resulting in the flap door opening and closing too large to close automatically.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a horizontal damping hinge for a flap door of a steam oven, comprising a hinge frame, the hinge frame being horizontally arranged at the bottom side of the flap door of the steam oven, a spring telescopic rod being arranged on the left side of an inner cavity of the hinge frame, an opening and closing hinge connecting piece being movably connected to the right side of the hinge frame through a rotating shaft, a fixed frame being fixedly connected to the left side of the bottom of the hinge frame, a fixed rod being laterally fixedly connected to the inner cavity of the fixed frame, a sliding sleeve being slidably connected to the left side of the surface of the fixed rod, a connecting block being fixedly connected to the top of the sliding sleeve, the top of the connecting block passing through the top of the fixed frame and being fixedly connected to the bottom of the spring telescopic rod, sliding columns being fixedly connected to the left and right sides of the bottom of the sliding sleeve, the bottom of the sliding column being slidably connected to the bottom of the inner wall of the fixed frame, and limiting rings being fixedly connected to the left and right sides of the surface of the fixed rod.

[0005] An opening is provided at the top of the fixing frame, the length of the opening is greater than the moving distance of the spring telescopic rod, and the width of the opening is less than one millimeter from the spacing between the connecting blocks.

[0006] A compression spring is sleeved on the surface of the fixing rod, the left side of the compression spring is fixedly connected to the right side of the sliding sleeve, and the right side of the compression spring is fixedly connected to the left side of the limiting ring.

[0007] A slide groove is provided at the bottom of the fixing frame. The length of the slide groove is greater than the moving distance of the slide column. The slide groove cooperates with the slide column.

The movement of the connecting block drives the sliding sleeve and the sliding column to move. When the sliding column moves in coordination with the sliding groove, the sliding sleeve works on the compression spring. The compression spring cooperates with the spring telescopic rod to reduce the power of the door opening and closing and reset the door to its initial position, thereby solving the problem that the existing damping hinge door opening and closing is too large to close automatically, reducing the labor of manual closing and increasing the convenience of using the oven.

[0012] 2. The present invention enables the connection block to completely pass through the opening for mechanical movement by setting the opening, thereby avoiding the phenomenon that the connection block moves to the edge of the opening and collides due to the opening being too short.

[0013] 3. The present invention can assist the sliding sleeve in working by setting the compression spring, and at the same time play the role of reset buffer, avoiding the vibration of the sliding sleeve due to friction during the movement, and reducing the friction resistance of the sliding sleeve during the movement. The present invention can assist the sliding column in working by setting the sliding groove, and at the same time play the role of limiting, avoiding the rotation of the sliding sleeve during the movement, and increasing the stability of the movement of the sliding column and the sliding bar.

[0014] 4. The present invention can assist the connection block in working by setting the rubber block, and at the same time play a protective role, avoiding the connection block from moving too long and colliding with the hinge frame, and also improving the safety of mechanical work. The present invention can increase the metal strength of the connection block by setting the connection block to be made of aluminum alloy, avoiding the connection block from being damaged or broken during long-term work, and also extending the service life of the connection block.
