The horizontal dual-spring hinge, as shown in fig. 2-3, includes: a housing 100, a swing arm 200, a main spring assembly 300, and a spring locking mechanism 400.

A housing 100, which is made of a metal material and has a long strip shape, and includes a bottom plate and two side plates perpendicular to the bottom plate, wherein the two side plates are symmetrically arranged along the length direction of the bottom plate;

the swing arm 200 is formed by punching a metal material, one end of the swing arm 200 is connected with one end of the shell 100 through a pin shaft, and the swing arm can be unfolded or closed relative to the shell 100;

the main spring assembly 300 is used for buffering when the swing arm 200 swings relative to the shell 100; the main spring assembly 300 includes: the main spring 310 and the inner bracket 320, one end of the main spring 310 is limited inside the casing 100, the other end is limited at the beginning of the inner bracket 320, and the end of the inner bracket 320 is connected with the swing arm 200.

The open end of the inner support 320 is connected with the outer shell 100 through a pin shaft, and the outer shell 100 is correspondingly provided with a second strip-shaped groove 102, so that when the swing arm 200 swings to further pull the inner support 320 to move, the pin shaft moves along the second strip-shaped groove 102; and the main spring 310 is deformed while the inner holder 320 is moved.

Referring to fig. 1, during assembly, the housing 100 is assembled on the main body of the device, and the swing arm 200 is assembled on the door body of the device, and the two are opened and closed by being turned up and down; and the elasticity stored by the main spring 310 in the process of swinging and opening the swing arm 200 (opening the door) can offset the weight of the door body at each angle in the process of opening and closing in a segmented manner, so that the door body can be opened and suspended at any angle, and the use is convenient.

The main body is a main body of an electric appliance, and the electric appliance can be various electric appliances such as a disinfection cabinet, an oven, a steam oven, a microwave oven and the like, or in a cabinet pull-down turnover structure.

The spring locking mechanism 400 is installed in the housing 100, and the spring locking mechanism 400 includes: a small spring 410, a pressure spring guide rod 420, and a pulley 430.

The spring locking mechanism 400 provides a locking force when the swing arm 200 is closed, so that the door body and the main body are tightly closed.

Specifically, the small spring 410 is limited between the pressure spring guide rod 420 and the baffle 110 in the housing 100;

the shell 100 is provided with the baffle 110 for limiting one end of the small spring 410 and a first strip-shaped groove 101 for limiting the pressure spring guide rod 420, the pressure spring guide rod 420 is limited through a first pin 500, and the first pin 500 penetrates through the first strip-shaped groove 101.

The pressure spring guide rod 420 has an arc-shaped slot 421 for mounting the pulley 430 and a rod 422 for assembling the small spring 410, the first pin 500 is mounted through the pulley 430, and the pulley 430 rotates in the arc-shaped slot 411.

Referring to fig. 4, when closing, the pulley 430 acts on the end wall 210 of the end of the swing arm 200 connected to the housing 100, and the small spring 410 provides a locking force for closing the swing arm 200, so that the closing is tighter.

A first arc-shaped section 201 and a second arc-shaped section 202 are arranged on an end wall 210 of the swing arm 200, and a corner position 203 is formed between the first arc-shaped section 201 and the second arc-shaped section 202, as shown in fig. 4, in a closed state, the pulley 430 is abutted against the first arc-shaped section 201, and in an opening process, the pulley 430 needs to slide to the second arc-shaped section 202 under the action of external force to overcome the resistance of the corner position 203, and then is separated from the second arc-shaped section 202 along with the continuous unfolding of the swing arm 200;

in some embodiments, the pulley 430 is required to overcome the resistance of the corner 203 during opening by an external force, and then is released from contact with the end wall 210 of the swing arm 200, i.e., not with the second arc segment 202, as the swing arm 200 is unfolded.

Referring to fig. 5, a first supporting point a is formed between the swing arm 200 and the housing 100 through a pin connection, and a second supporting point B is formed between the open end of the inner support 320 and the housing 100 through a pin connection; a third supporting point C is formed between the first pin 400 and the housing 100; the first supporting point A, the second supporting point B and the third supporting point C are limited in a triangular mode, and the static bearing function is achieved.

And it can be seen from figure 5 that the pulley 430 has moved away from the end wall 210 of the swing arm 200.

In a further technical solution, the inner frame 320 includes: the first support plate 321 and the second support plate 322 are bilaterally symmetrical, the spring locking mechanism 400 is located or partially located between the first support plate 321 and the second support plate 322, one side of the inner support 320 is provided with a track groove 323 for the first pin 500 to move, and a positioning groove point 324 is formed at the tail end of the track groove 323.

As the pulley 430 leaves the end wall 210 of the swing arm 200, the first pin 300 moves along the track groove 323, and in the maximum open position, the first pin 300 falls into the detent point 324.

Through the structure, in the opening process, the main spring 210 can offset the weight of the door body at each angle in the opening and closing process in a segmented manner, so that the door body can be opened and can hover at any angle; and when the swing arm is closed, the spring locking mechanism 400 can provide locking force for closing the swing arm 200, so that the swing arm is closed more tightly.

In a further technical scheme, referring to fig. 6, a plurality of limiting holes 220 are formed in the swing arm 200, and when the limiting holes 220 are pre-assembled, a limiting pin 600 is inserted into the limiting holes 220, so that the limiting function of the hinge pre-assembled door body is achieved, and the door body is convenient to assemble.
