DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0026] See Figures 1 to 4 As shown, a top and bottom hinge with a reinforced stable structure includes a door panel connecting seat 1 and a hinge shell 2, a hinge structure 3 is arranged in the hinge shell 2, a transmission plate structure 4 is arranged between the hinge structure 3 and the door panel connecting seat 1, the hinge structure 3 includes a hinge core bracket plate 31 and a thrust spring 32, a spring mounting area 33 is provided on the hinge core bracket plate 31, and a thrust spring swing rod 34 is provided at the center of the thrust spring 32. In this embodiment, the above structures are all existing technical structures in the patent technology in the background technology, so they are not recorded in detail. Please refer to the patent technical solution in the background technology for details.

[0027] A swing support 5 is provided between the bottom end of the thrust spring 32 and the bottom wall of the spring mounting area 33. In this embodiment, the swing support 5 is a metal structure. The addition of the swing support 5 allows the swing support 5 to swing synchronously with the swing of the thrust spring 32, thereby maintaining the thrust spring 32 vertical. This helps to solve the technical problem of the thrust spring 32 bending due to excessive swinging angle or causing wear and tear of the thrust spring 32 due to swinging.

[0028] During actual installation, the bottom end of the thrust spring swing rod 34 is inserted into the center of the swing support 5, and the bottom end of the thrust spring 32 is snapped onto the swing support 5. The movement of the thrust spring 32 drives the swing support 5 to swing synchronously and keeps the thrust spring 32 vertical.

[0029] In actual use, an arc-shaped limiting groove 15 is provided in the middle of the bottom wall of the spring mounting area 33, and an arc-shaped limiting protrusion 16 is integrally formed on the side wall of the swing support 5. The arc-shaped limiting protrusion 16 is disposed in the arc-shaped limiting groove 15. With the above structure, the swing support 5 can be reset through the arc-shaped limiting groove 15 during operation, thereby improving the stability of use.

[0030] At the same time, in order to solve the problem of door panels sagging in the prior art, in this embodiment, a door panel seat bracket piece 6 and an up and down adjustment slider seat 7 are provided in the door panel connecting seat 1;

[0031] The vertical adjustment slider seat 7 is provided with an inclined slider adjustment slot 8, with an angle of 15-30 degrees. An adjustment slider 9 is positioned within the adjustment slot 8. The adjustment slot 8 has a square cross-section, and the adjustment slider 9 is a parallelepiped slider. Because the adjustment slot is inclined, the adjustment slider 9 moves along the inclined edge when it is raised or lowered, thereby adjusting the door panel to prevent it from sagging.

[0032] The connecting door panel seat bracket plate 6 is rotatably connected to the door panel connecting seat 1 through a directional shaft 10, and the transmission plate structure is rotatably connected to the connecting door panel seat bracket plate through a shaft rod 11; this structure is a conventional setting of the prior art and is simply applied, so it is not recorded in detail. Please refer to the patent document of the background technology for details.

[0033] The upper and lower adjustment slider seat 7 is attached to the side surface of the door panel seat support plate and is fixed by a screw 12. The bottom surface of the door panel connection seat 1 is provided with an adjustment screw 13. The top of the adjustment screw 13 penetrates the slider adjustment slot 8 and is threadedly connected to the adjustment slider 9. In this embodiment, in actual application, the bottom surface of the upper and lower adjustment slider seat is a strip groove, that is, the screw can move within the strip groove, or it can be hollowed out, that is, it does not affect the movement of the screw. When the adjustment screw 13 rotates, the adjustment slider 9 is moved up and down within the slider adjustment slot 8 under the action of the adjustment screw 13 to achieve adjustment. When the adjustment screw rotates, the adjustment slider 9 rises and falls within the slider adjustment slot and moves under the guidance of the inclined edge, which drives the upper and lower adjustment slider seat 7 to move, achieving the adjustment operation.

[0034] In actual application, the top surface of the adjusting slider 9 is provided with a limiting snap ring 14 that is positioned at the top of the adjusting screw 13. The limiting snap ring 14 can limit the adjusting screw to prevent the adjusting slider from falling off the adjusting screw, thereby ensuring the effectiveness and reliability of the connection.

[0035] The present invention has positive effects:

[0036] 1. The present invention has a reasonable structure. A swing support is provided between the thrust spring and the bottom wall of the spring installation area. When the thrust spring swings, the swing support can swing synchronously to keep the thrust spring vertical. This helps to solve the technical problems of the thrust spring bending due to excessive swinging angle caused by the swing of the thrust spring, or the thrust spring being worn and broken due to the swinging. It can improve the stability and service life of the thrust spring and improve the stability.

[0037] 2. There are upper and lower adjustment slider seats in the door panel connecting seat, which are connected to the adjustment slider through the adjusting screw thread. When the adjusting screw is rotated, the adjustment slider can be driven to rise and fall in the slider adjustment slot, thereby driving the upper and lower adjustment slider seats to move, thereby realizing the adjustment of the door panel connecting seat, which is beneficial to prevent the door panel from sagging and improves the stability of use.
