Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] Improved hinge, shown in Figure 7, please refer to [reference needed]. Figure 1 - Includes: a housing 100, a head 200 rotatably connected to one end of the housing 100, a tension spring assembly 300, and a buffer assembly 400; the head 200 is equipped with a latch 210, the latch 210 is rotatably mounted on the head 200, and when the hinge is installed on the device, the latch 210 keeps the head 200 and the housing 100 at an installation angle, characterized in that: the latch 210 is provided with a first limiting part 211 and a second limiting part 212; the head 200 is provided with a radially protruding protrusion 220, after the latch 210 is rotated, the second limiting part 212 abuts against the protrusion 220, and the first limiting part 211 abuts against the housing 100.

[0030] Specifically, the outer shell 100 is a long, rectangular frame, and one end of the head 200 is rotatably connected to one end of the outer shell 100 by rivets and pulleys, allowing it to swing relative to the outer shell 100.

[0031] Furthermore, such as Figure 4 As shown, the latch 210 includes a left latch plate and a right latch plate arranged symmetrically, and the head 200 can be inserted between the left latch plate and the right latch plate; the first limiting part 211 is provided at the upper end of the latch 210; the second limiting part 212 is provided at the lower end of the latch 210, and the lower end of the latch 210 is provided with a mounting hole;

[0032] The entire latch 210 is formed by pressing or bending metal material; the first limiting part 211 protrudes radially outward on the left latch plate and the right latch plate respectively, and can stably press against the outer shell 100; while the second limiting part 212 is hook-shaped and limits the protrusion 220.

[0033] like Figure 5 As shown, when the head 200 is at the installation angle, the first limiting part 211 of the latch 210 presses against the outer shell 100, and the second limiting part 212 presses against the protrusion 220, thereby constraining the hinge assembly and disassembly angle and preventing the latch 210 from opening too much or too little during the assembly and disassembly process, which would ultimately lead to the failure of the hinge function.

[0034] Furthermore, the latch 210 is rotatably mounted to the head 200 by means of rivets.

[0035] In one embodiment, the tension spring assembly 300 includes an inner support 310 and a tension spring 320. Specifically, the head 200 is connected to the end of the inner support 310, and a rivet is provided at the opening of the inner support 310, which is positioned within the first slot 110 of the outer casing 100.

[0036] The opening of the tension spring 320 is limited at the outer shell 100, and the end of the tension spring 320 is limited at the rivet at the opening of the inner bracket 310.

[0037] In one embodiment, the buffer assembly 400 includes: a spring pin 410, a spring 420, and a pulley 430; the spring 420 is sleeved on the spring pin 410;

[0038] When the pulley 430 is limited to the end of the spring pin 410 by a rivet, and the head 200 is in the closed position, the pulley 430 is pressed against the head 200 by the elastic force of the spring 420.

[0039] Specifically, the pulley 430 is pressed against the end face 201 of the head 200; the rivet of the pulley 430 is limited in the second slot 120 of the outer shell 100;

[0040] like Figure 5 As shown, a limiting plate is provided inside the outer casing 100, and a groove is provided on the limiting plate. The opening of the spring needle 410 passes through the groove, so that the spring needle 410 can move stably.

[0041] The specific use of this utility model is further explained below:

[0042] like Figure 5 As shown, the head 200 rotates relative to the outer shell 100 to the installation angle. At this time, the latch 210 has completed its rotation. The first limiting part 211 at the upper part of the latch 210 is pressed against the outer shell 100, and the second limiting part 212 at the lower part of the latch 210 is pressed against the protrusion 220. The latch 210 prevents the head 200 from continuing to rotate around the outer shell 100, thus limiting its rotation and facilitating the installation and removal of the hinge.

[0043] contrast Figure 5 and Figure 7 Obviously, Figure 5 The central locking buckle 210 is turned clockwise to extend the head 200, while Figure 7 The central locking buckle 210 is limited to the head 200.

[0044] like Figure 6 As shown, with the hinge closed, the head 200 and the outer casing 100 are approximately at 90°. At this time, the pulley 430 moves the spring force of the compression spring 420 against the end face 201 of the head 200, making the hinge closed and stable. Then, a force is applied to rotate the head 200 counterclockwise. During the rotation, due to the change in the curve of its end face 201, the head 200 pushes the pulley 430 to move the spring pin 410 to the right, and the spring 420 is compressed. Figure 7 As shown, when the head 200 is opened to its maximum angle, the pulley 430 moves away from the end face 201 of the head 200; at this time, the tension spring 320 is stretched, providing a pulling force to the right of the head 200.

[0045] When force was applied again, the head was 200... Figure 7 Rotate the position clockwise to Figure 6 During the rotation of the head 200, its end face 201 contacts the pulley 430 again. After the head 200 rotates to the closing angle, the pulley 430 presses the end face of the head 200 again. During the closing process, the compression spring 420 plays a buffering role.

[0046] The improved hinge of this utility model uses the limiting action of the latch to position the head 200 and the outer shell 100 at the installation angle during installation and disassembly, so as to achieve quick and stable assembly and disassembly; at the same time, the head 200 can achieve slow opening and closing during the closing and opening process.

[0047] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
