Detailed Description

The present invention will be further described with reference to the accompanying drawings. The utility model provides a can match hinge that multiple weight door body used, its includes main part 1 and articulated the hinge arm 2 of installing above that, still articulates on the hinge arm 2 and installs single arm-drag 3, and in the guide way 5 of the 3 other ends of single arm-drag 4 slidingtype installations on main part 1 through the guide post, be provided with extension spring 6 between main part 1 and the single arm-drag 3, extension spring 6 stimulates the hinge arm 2 through single arm-drag 3 all the time and closes its characterized in that: the main body 1 is internally provided with a friction plate 8 in a vertically sliding mode through a guide nail 7, the guide column 4 stretches across the top of the friction plate 8, an elastic device is arranged between the friction plate 8 and the main body 1 and pushes the friction plate 8 to be always upwards jacked to be in contact with the guide column 4, and when the hinge is opened and closed, the guide column 4 and the friction plate 8 rub with each other to generate movement resistance.

The surface of the guide post 4 is sleeved with a roller 9, and the roller 9 is positioned on the top of the friction plate 8 to slide.

The friction plate 8 is in a long waist shape, guide holes 81 are arranged at the head end and the tail end of the friction plate, and the guide nail 7 penetrates through the guide holes 81 to be fixedly connected with the main body 1.

The elastic device is a spring 82, the spring 82 is sleeved outside the guide nail 7, and the upper end and the lower end of the spring 82 are respectively pressed against the main body 1 and the friction plate 8.

The upper end face of the friction plate 8 is provided with a positioning groove 83 which is concave downwards, and after the hinge is closed, the guide column 4 is buckled in the positioning groove 83.

The main part 1 in still be provided with balance plate 12, balance plate 12 one end is articulated with single arm-drag 3 through guide post 4, the other end of balance plate 12 is installed in the spacing groove 14 on main part 1 through sliding column 13 slidingtype, the extension spring hang and detain on sliding column 13.

The working principle is as follows: when the hinge is opened to the set angle, the tension of the spring is matched with the counter-tension of the box door, so that the box door can be stopped at will in a specific angle, and the hinge is convenient for a user to use. In order to adapt to the use of the hinge for mounting the box doors with different weights (within an adaptive range value), a friction plate 8 is vertically and slidably mounted in a main body 1 through a guide nail 7, a guide column 4 stretches across the top of the friction plate 8, an elastic device is arranged between the friction plate 8 and the main body 1, the elastic device pushes the friction plate 8 to be always upwards jacked to be in contact with the guide column 4, and when the hinge is opened and closed, a pull arm pulls the guide column 4 and the friction plate 8 to rub with each other to generate movement resistance. Through this movement resistance, resistance when increasing the hinge switching, consequently, when the chamber door of different weight and this hinge match the use, still can be through the gravity phase-match of damping force and chamber door that increases, realize that the chamber door weight of wider within range can stop wantonly in the angle of settlement, promote the application scope (a section is multi-purpose promptly) of this hinge. Meanwhile, a positioning groove 83 which is recessed downwards is formed in the friction plate, and the guide post 4 is buckled into the positioning groove 83 after the hinge is closed. The locking function of the box door is achieved, and the box door is prevented from being opened under non-operation after being closed.

Further: in order to improve the smoothness in the switch, a balance plate 12 is further arranged in a main body 1 in the scheme, one end of the balance plate 12 is hinged to a pull arm 3 through a guide column 4, the other end of the balance plate 12 is installed in a limiting groove 14 in the main body 1 in a sliding mode through a sliding column 13, a tension spring is hung and buckled on the sliding column 13, the balance plate can play a role in connecting the pull arm and the tension spring, an angle difference does not exist between the pull arm and the tension spring, the phenomenon that the pull arm is damaged due to oblique movement or is scratched with the main body to generate abnormal sound due to oblique stress of the spring is avoided, the stability and the smoothness in the operation of the hinge are improved, and the hinge can be widely popularized and used.
