The swing arm is installed on the oven door, the base is installed on the oven cabinet, the swing arm and the base are hinged, the spring is sleeved on the pull rod, and the pull rod is connected to the base and the swing arm. Then, relying on the tension or elastic force of the spring, the torsion and pulling method is adopted. When opening the door, the door can be stretched or compressed by pulling the door open, so that the oven door can be opened; when closing, just let go of the oven door, and the oven door will be closed on the oven cabinet due to the reset effect of the spring.

[0003] However, the oven hinge of the above structure has the following disadvantages:

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] According to the attached Figures 1 to 6 As shown in the figure, the oven hinge mechanism with door closing force of the utility model comprises a fixed seat 1 installed on the door body, a swing arm 2 installed on the cabinet body, the swing arm 2 is rotatably connected to the fixed seat 1, and the fixed seat 1 is provided with a transmission component for opening and hovering the door body and a closing assist component for making the door body have closing force. The transmission component comprises a linkage frame 3, and the closing assist component comprises a guide rod 5, a compression spring 6, and a rolling connection group 7. The linkage frame 3 is arranged in the fixed seat 1 and is axially connected to the swing arm 2. One end of the guide rod 5 is clamped on the linkage frame 3, and the other end of the guide rod 5 is axially connected to the rolling connection group 7. The compression spring 6 is sleeved on the guide rod 5, and the two elastic ends of the compression spring 6 are respectively connected to the linkage frame 3 and the rolling connection group 7, so that the rolling connection group 7 is always slidably connected to the outer edge of the swing arm 2 as the door body opens and closes.

[0026] In actual operation, the outer edge of the swing arm 2 is provided with a flange 22 which can be slidably connected to the roller 71 as the door body opens and closes.

[0027] Under the elastic action of the compression spring 6 of the closing assist assembly, the rolling connection group 7 is always connected to the convex edge 22 of the swing arm 2.

[0028] Reference Figures 1 to 6As shown, the swing arm 2 is provided with a locking groove 21 that is matched with the rolling connection group 7. The rolling connection group 7 includes a roller 71 and a connecting bracket 72. The connecting bracket 72 is installed on the guide rod 5 and connected to an elastic end of the compression spring 6. The roller 71 is rotatably connected to the roller 71 bracket and is always compressed and connected to the swing arm 2 under the elastic action of the compression spring 6.

[0029] In practical application, the linkage frame 3 includes a front linkage part 31 and a rear linkage part 32. The front end of the front linkage part 31 is connected to the swing part shaft of the swing arm 2 through a linkage shaft 9, the guide rod 5 is arranged in the front linkage part 31, and the front linkage part 31 is provided with a positioning block 33 for adapting the guide rod 5 to move forward and backward linearly under the action of the compression spring 6, the rear linkage part 32 is connected with a tension spring 4, the tension spring 4 is buckled on the fixed seat 1, and the rear linkage part 32 is provided with a connecting shaft 10 for matching and buckling with the tension spring 4. In addition, limiting grooves 11 for limiting the moving position of the connecting shaft 10 are provided on both sides of the fixed seat 1.

[0030] When the hinge is opened or closed, the fixed seat 1 rotates relative to the swing arm 2 with the axis as the fixed point, and the tension spring 4 and the linkage frame 3 of the transmission assembly provide transmission force for the fixed seat 1, so that the elastic force of the tension spring 4 provides a torque force to balance the weight of the oven door, so that the oven door can be opened and hovered at any angle, which improves applicability and enhances stability.

[0031] During this period, under the structural coordination of the guide rod 5, compression spring 6, and rolling connection group 7 of the closing assist assembly, when the oven door rotates between 0° and 15° (including 0°), the tension spring 4 torque = elastic force * lever arm. As the oven door rotates, the torque generated by the door weight becomes smaller and smaller, and the elastic force generated by the tension spring 4 being stretched also becomes smaller and smaller, and even the elastic force returns to the original state. At this time, the roller 71 slides onto the locking groove 21 as the oven door rotates inward, and at the same time, under the action of the compression spring 6, it provides a greater automatic closing assist for the fixing seat 1, so that the oven door has an automatic door closing function, with a simple structure and easy operation, and the closing density of the oven door is enhanced to ensure the use effect of the oven.

[0032] The positioning end of the swing arm 2 is axially connected to the fixed seat 1 through the main shaft 8, and one end of the linkage frame 3 is connected to the swing part of the swing arm 2 through the linkage shaft 9. The locking groove 21 is provided on the swing arm 2 above the linkage shaft 9, and the roller 71 slides into the locking groove 21 from the outer edge of the swing arm 2 as the door body is closed, so that the main shaft 8, the linkage shaft 9 and the rotation axis of the roller 71 form a straight line of three points.

[0033] In this way, the swing arm 2 of the present structure cooperates with the fixed seat 1 and the linkage frame 3 to effectively reduce the amount of sinking of the oven door when it is opened, avoid interference and collision between the oven door and the furniture cabinet on which the oven is installed during the opening process, and ensure the normal opening and use of the oven door.

[0034] Furthermore, since the main shaft 8, the linkage shaft 9 and the rotating shaft of the roller 71 form a straight line, a closing force of the locking roller 71 is generated, so that the oven door has a closing function and the stability of the product is improved.

[0035] The above specific embodiments are only specific implementation methods with better effects of the utility model. Any structure that is the same or equivalent to the oven hinge mechanism with door closing force of the utility model is within the protection scope of the utility model.
