However, the conventional hinge's damper mounting structure has the following disadvantages in the hinge cup opening and closing process: 1) The buffer damper is arranged at the tail end of the hinged support, the structure is complex, the disassembly and assembly are difficult, the buffer damper which runs linearly is always connected with the pushing rod through the transmission component, and when the hinge cup is closed and opened at a certain angle, the buffer stroke of the buffer damper which runs linearly is long, so that the buffer damper is difficult to always provide corresponding buffer force along with the opening and closing of the hinge cup, the buffer effect is affected, particularly, the hinges of the middle bent arm and the large bent arm are easy to cause the position deviation of the buffer damper and the transmission component to cause the blocking, and the door cannot be normally opened and closed; 2) The buffer damper generally adopts a buffer oil cylinder, the cylinder body of the buffer oil cylinder is fixed on the hinge arm, and the push rod of the buffer oil cylinder is in point contact with the torsion spring, so that the push rod is easily separated from the torsion spring due to vibration, the stability of buffer operation is influenced, even if gaps are formed between the radial directions of the torsion spring along with long service time, the push rod of the buffer oil cylinder is easily inserted into the gaps, the buffer effect is invalid, the normal use of the hinge is seriously influenced, and further improvement is necessary.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides the hardware buffer hinge which is simple in structure, convenient to use, capable of effectively prolonging the service life of a buffer and enabling the hinge to work more stably.
The utility model aims at realizing the following modes: the hardware buffer hinge comprises a hinge arm and a hinge cup, wherein the hinge arm is hinged with the hinge cup through an upper connecting rod and a lower connecting rod, and a four-connecting-rod structure is formed among the hinge arm, the hinge cup, the upper connecting rod and the lower connecting rod; the method is characterized in that: the hinge arm is characterized in that an accommodating cavity is formed in the hinge arm, a driving shell is fixedly arranged in the accommodating cavity, a buffer is arranged in the driving shell, a piston rod of the buffer extends out of the driving shell and is propped against a baffle plate arranged in the accommodating cavity, a driving arm is arranged on the lower connecting rod and is propped against a driving plate on the side wall of the buffer, and when the hinge is opened and closed, the driving arm pushes the buffer to slide back and forth in the driving shell through the driving plate.
The baffle is formed by bending the material of the hinge arm body into the accommodating cavity.
The baffle is independently formed and fixed in the accommodating cavity by welding.
The bottom of the side wall of the driving shell is provided with a mounting seat, and the locating pin penetrates through the mounting seat to be fixed with the hinge arm.
The beneficial effects of the utility model are as follows: 1. simple structure, low production cost and market competitiveness improvement. 2. The piston rod of buffer pushes up on setting up the baffle in the arm of hinging, and the baffle can effectively keep apart the buffer rod and directly bear on the torsional spring, avoids the flexible work of influence buffer because of torsional spring twists when the hinge switching, guarantees the life of hinge.

Detailed Description
The utility model is described in more detail below with reference to the accompanying drawings. The hardware buffer hinge comprises a hinge arm 1 and a hinge cup 2, wherein the hinge arm 1 and the hinge cup 2 are hinged through an upper connecting rod 3 and a lower connecting rod 4, a four-connecting-rod structure is formed among the hinge arm 1, the hinge cup 2, the upper connecting rod 3 and the lower connecting rod 4, a torsion spring 12 is arranged between the upper connecting rod and the hinge arm, and the hinge arm is always pushed to swing towards the closing direction; the method is characterized in that: the hinge arm 1 in be provided with holding chamber 5, holding intracavity 5 internally fixed mounting has drive shell 6, installs buffer 7 in the drive shell 6, the piston rod of buffer 7 extends outside the drive shell 6, with setting up baffle 8 roof pressure in holding intracavity 5, lower connecting rod 4 on be provided with actuating arm 9 roof pressure on the drive plate 10 of buffer 7 lateral wall, during hinge switching, actuating arm 9 promotes buffer 7 through drive plate 10 and slides back and forth in drive shell 6.
The baffle plate 8 is formed by bending the material of the body of the hinge arm 1 into the accommodating cavity 5.
The baffle plate 8 is independently molded and fixed in the accommodating cavity 5 by welding.
The bottom of the side wall of the driving shell 6 is provided with a mounting seat 11, and a positioning pin 121 penetrates through the mounting seat 11 to be fixed with the hinge arm 1.
Working principle: when the hinge works, the driving arm 9 is arranged on the lower connecting rod 4 to be propped against the driving plate 10 on the side wall of the buffer 7, and when the hinge is opened and closed, the driving arm 9 pushes the buffer 7 to slide back and forth in the driving shell 6 through the driving plate 10, so that the buffering function is achieved when the hinge is closed. When the buffer works, a piston rod of the buffer 7 extends out of the driving shell 6 and is propped against the baffle plate 8 arranged in the accommodating cavity 5, the pressure from the buffer is borne by the baffle plate, and when the pressure of the baffle plate is insufficient for supporting, the baffle plate can be borne on the torsion spring at the rear end of the baffle plate, so that the supporting force of the baffle plate is ensured. The buffer rod of the buffer can be prevented from being directly borne on the torsion spring by the baffle, so that transverse thrust is not generated due to torsion of the torsion spring when the hinge is opened and closed, and finally the buffer rod is bent and deformed, or the buffer rod radially prizes the sealing ring of the buffer main body, and the buffer is prevented from being blocked or damaged. The hinge is favorable for ensuring the stable and efficient operation of the hinge and prolonging the service life of the hinge, so the hinge can be widely popularized and used.
