Problems solved by technology

[0004] 1. The bearing capacity is poor. When the weight of the door body is large, the hinge is easy to deform, which affects the normal use of the flap door
[0005] 2. When the flap door is opened upwards, it is necessary to overcome the weight of the door body first, the load is heavy, laborious and inconvenient to use
[0006] 3. It cannot be closed automatically, and it needs external force to achieve the closing effect. Use a single
[0007] 4. The flip door can only open the door at 90°, which limits the opening range of the door and cannot meet the needs of users
[0008] 5. It can only drive the flap door to rotate upwards to open or close, that is, it can only be fully opened or completely closed, and the use status is limited, which affects the use effect

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings.

[0032] According to attached Figure 1 to Figure 6 As shown, the upturning door hinge with opening and closing assistance of the present invention includes a door bracket 1 fixedly installed with the door body, and a hinge seat 2 fixedly installed with the cabinet body. Wherein, the connection between the hinge base 2 and the door bracket 1 is hinged with a transmission assembly for driving the door to open and close on the cabinet. The transmission assembly includes a transmission link group 3, a rotating cam 4, and a spring 5. The center point shaft of the rotating cam 4 is connected to the hinge base 2, the swing end of the rotating cam 4 is hinged with the positioning end of the transmission link group 3, and the driving end of the transmission link group 3 is hinged with the door bracket 1. The positioning end of the spring 5 is installed on the hinge base 2, and...

Abstract

The invention provides an upturning door hinge with opening and closing assistance. The upturning door hinge comprises a door support, and a hinge seat; a transmission assembly is hinged among the hinge seat and the door support; the transmission assembly comprises a transmission connecting rod group, a rotary cam, and a spring; a central point of the rotating cam is in shaft connection with the hinge seat; a swing end of the rotary cam is hinged with the positioning end of the transmission connecting rod group; the pushing end of the transmission connecting rod group is hinged with the door support; a positioning end of the spring is mounted on the hinge seat; a movable end of the spring is provided with a bearing which is tangentially connected with the outer edge of the rotary cam underthe elastic action; a tangent point of the bearing tangent to the outer edge of the rotating cam is located below or above a connecting line of the bearing and the central point of the rotating cam and generates a door closing torque or a door opening torque for pushing the rotating cam to rotate. The upturning door hinge with opening and closing assistance achieves automatic opening and closing,saves labor,, reduces deformation, improves convenience, structural stability and reliability, realizes high applicability, and guarantees using quality of products.

Description

technical field [0001] The invention relates to the field of upturning door hinges, in particular to an upturning door hinge with opening and closing assistance. Background technique [0002] The existing flip door hinge includes a main body, a spring, a hook lock and a hook; the spring, the hook lock and the hook are respectively installed on the main body; the hook and the spring are respectively connected with the hook lock. The elastic force of the spring is used to support and open the flap, so that the flap does not hang down and prevents the flap from rebounding at any angle. [0003] In actual operation, the above-mentioned flip door hinge has the following deficiencies: [0004] 1. The bearing capacity is poor. When the weight of the door body is heavy, the hinge is easily deformed, which affects the normal use of the flap door. [0005] 2. When the flap door is opened upwards, it is necessary to overcome the weight of the door body first, the load is heavy, labor...
