Detailed Description
The invention is further described below with reference to the accompanying drawings.
Referring to fig. 1 to 3, the oven hinge with opening and closing assistance function of the present invention includes a base 1 installed on a cabinet body, and a swing arm 2 installed on a door body, wherein the swing arm 2 is hinged to the base 1 through a connecting shaft 13. The base 1 is provided with a transmission elastic component for stable rotation of the swing arm 2 and a power-assisted elastic component for driving the door body to open and close by the aid of the swing arm 2.
Wherein, the transmission elastic component comprises a connection elastic part 3 and a transmission part 4. The connecting elastic piece 3 is fixed in the base 1 through a fixing pin 5 and is installed with one end part of the transmission piece 4 through a sliding shaft 6 in a matching mode, the sliding shaft 6 is connected on the base 1 in a sliding mode, and the other end part of the transmission piece 4 is hinged to the lower end part of the swing arm 2 through a fixing shaft 7. The fixing pin 5, the sliding shaft 6, and the fixing shaft 7 are not on the same horizontal line, and the fixing shaft 7 is located above the connecting shaft 13.
The operating principle of operating the oven door is as follows: when the swing arm 2 rotates by taking the connecting shaft 13 as a fixed point and forms a torque with the base 1 smaller than the torque at the two ends of the connecting elastic piece 3, an included angle of 0-15 degrees for generating self-closing force is formed between the door body and the cabinet body. That is, when the oven door body rotates between 0 ° and 15 ° (including 0 °), the torque of the connection elastic member 3 is multiplied by the moment arm by the elastic force, and as the torque generated by the door weight is larger and larger when the oven door body rotates, the elastic force generated by stretching the connection elastic member 3 is also increased, which is enough to make the torque generated by the connection elastic member 3 be enough to automatically close the oven door body on the oven cabinet body.
When the swing arm 2 rotates by taking the connecting shaft 13 as a fixed point and forms a torque with the base 1 which is equal to the torque at the two ends of the connecting elastic part 3, an included angle of 15-70 degrees for generating balance force is formed between the door body and the cabinet body. That is, when the oven door body rotates at 15 ° to 70 °, the torque generated by the door weight when the oven door body rotates becomes larger and larger, the elastic force generated by stretching the connecting elastic member 3 is increased, and the torque generated by the connecting elastic member 3 can balance the gravity of the oven door body, so that the oven door body stays at any angle according to practical application when opened.
When the swing arm 2 rotates with the connecting shaft 13 as a fixed point and forms a torque with the base 1 which is larger than the torque at the two ends of the connecting elastic part 3, an included angle of 70-85 degrees which generates a self-opening door force is formed between the door body and the cabinet body. That is, when the oven door body rotates at 15 ° to 70 °, the torque generated by the door weight when the oven door body rotates becomes larger and larger. At this time, the base 1 is provided with a stopper groove 15 for sliding in cooperation with the slide shaft 6. When the sliding shaft 6 slides to the leftmost side, the elastic force generated by stretching the connecting elastic piece 3 is unchanged, so that the torque generated by the connecting elastic piece 3 is smaller than the torque generated by the gravity of the oven door body, and the oven door body is automatically opened.
Like this, under the structure cooperation of transmission elastic component's connection elastic component 3, driving medium 4, connect elastic component 3 atress all the time, the moment of torsion that makes door torsion angle produce forms the mutual transmission effort relation between the door body and the base 1 with the moment of torsion of being connected elastic component 3 to stop in arbitrary angle when reaching the oven door body and opening, improve the suitability, can make the oven door body have again and help and open and close a body function, strengthen stability.
In addition, the other end of the transmission member 4 is mounted with a flexible connection block 14 slidably connected to the wall surface of the base 1 as it moves. The fixing pin 5, the sliding shaft 6 and the fixing shaft 7 are matched with a structure which is not on the same horizontal line, and the double protection structure is adopted, so that the transmission stability is high, the friction is reduced, and the noise is reduced.
Referring to fig. 1 to 3, a base 1 is provided with an assisting elastic component for driving a door body to open and close by an assisting swing arm 2. The power-assisted elastic component comprises a power-assisted frame 8, a supporting plate 9 and a power-assisted elastic part 10, wherein the power-assisted frame 8 is arranged at the upper end of the base 1, and the power-assisted elastic part 10 acts on the supporting plate 9 to elastically reset and move relative to the power-assisted frame 8. A connecting wheel 11 is installed at one end of the supporting plate 9, and the swing arm 2 is provided with an arc groove 12 for connection with the connecting wheel 11 when the swing arm is closed inwards or opened outwards.
In practical application, the connecting wheel 11 is assembled on the positioning shaft 21, and the arc groove 12 is provided with an arc surface 23 which gradually changes from surface contact to line contact with the connecting wheel 11 along with the outward swinging of the swinging arm 2.
When the oven door body is closed at the cabinet body, the oven door body is compressed on the connecting wheel 11, under the effect of the power-assisted elastic part 10, the arc surface 23 of the power-assisted arc slot 12 is in surface contact with the connecting wheel 11, and the reinforced swing arm 2 is tightly connected to the base 1, so that the oven door body is tightly closed on the oven cabinet body under the dual effects of the power-assisted elastic component and the transmission elastic component, the wrong door body is effectively prevented from being opened or automatically opened, and the connection stability is improved.
When the oven door body is opened, along with the rotation of the oven door body, the arc groove position 12 and the connecting wheel 11 are in line contact gradually by surface contact, and the supporting plate 9 is elastically reset and moved relative to the power-assisted frame 8 under the action of the power-assisted elastic piece 10, so that the swinging arm 2 is assisted to be opened and closed, and the opening or closing operation of the oven door body is easier.
And the base 1 is provided with a positioning column 16 and an installation opening 17, and one end of the power-assisted frame 8 is provided with a positioning hole 18 for matching and installing the positioning column 16 and an installation fixture block 19 which is matched and slidably installed on the installation opening 17. Make helping hand elastic component 10 demountable installation on base 1, convenient assembling, the structure is firm, ensures oven hinge's result of use.
In addition, the inner side of the power-assisted frame 8 is provided with a limiting block 20 for limiting the elastic reset movement of the supporting plate 9, one end of the supporting plate 9 is inserted on the limiting block 20, the other end of the supporting plate 9 slides on the power-assisted frame 8 through a positioning shaft 21, and the power-assisted frame 8 is provided with a sliding hole 22 matched with the positioning shaft 21 for sliding connection. The power-assisted elastic part 10 runs stably, the connection stability is enhanced, and the use quality of the oven is improved.
The above embodiments are only embodiments with better effects, and any structure identical or equivalent to the oven hinge with opening and closing assisting function of the present invention is within the protection scope of the present invention.
