Description

Technical Field

[0001] This utility model relates to the field of cabinet door opening and closing technology, specifically to an upward-opening door structure. Background Technology

[0002] Traditional top-hinged door structures use two gas springs to achieve the opening and closing function. This structure is only suitable for lighter top-hinged door structures. For heavy-duty top-hinged doors, the traditional structure requires a lot of force and cannot be easily opened and closed, which is time-consuming and laborious. In addition, the traditional top-hinged door structure has problems such as repeated adjustment of the installation position during installation, difficulty in selecting the gas spring push force, and exposed gas spring push rods that are prone to dirt and are unsightly. Utility Model Content

[0003] The purpose of this utility model is to provide an upward-opening door structure that is easy to install, saves time and effort, and solves the problem that the existing upward-opening door structure is not suitable for heavy-duty upward-opening door opening and closing.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a lifting door structure is provided, including: a bracket and a lifting door; the two sides of the lifting door are respectively rotatably engaged with the bracket through a rotating shaft, and the rotating shaft is respectively connected to the bracket through a support component;

[0005] The support assembly includes a connecting rod, a gas spring, and an elastic support component; one end of the connecting rod is fixedly connected to the rotating shaft, the other end of the connecting rod is rotatably connected to one end of the gas spring, the other end of the gas spring is rotatably connected to the bracket, one end of the elastic support component is rotatably connected to the middle of the connecting rod, and the other end of the elastic support component is rotatably connected to the bracket.

[0006] Furthermore, the elastic support assembly includes a sleeve, a slide rod, and a spring; one end of the slide rod slides into the sleeve, and the other end of the slide rod is rotatably connected to the middle of the connecting rod; the end of the sleeve away from the slide rod is rotatably connected to the bracket; a first limiting member is provided on the outside of the slide rod, a second limiting member is provided on the outside of the sleeve, and the spring is sleeved on the outside of the sleeve, with both ends of the spring connected to the first limiting member and the second limiting member respectively.

[0007] Furthermore, the second limiting member is connected to the side wall of the sleeve by a thread, which is used to adjust the distance between the second limiting member and the first limiting member.

[0008] Furthermore, the first limiting component is located on the side of the slide bar away from the sleeve.

[0009] Furthermore, the sleeve is rotatably connected to the first fixed seat, which is mounted on the bracket.

[0010] Furthermore, the end of the gas spring away from the connecting rod is rotatably connected to the second fixed seat, which is mounted on the bracket.

[0011] Furthermore, the rotating shaft is rotatably engaged with the third fixed seat, which is mounted on the bracket.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a combination of a gas spring and an elastic support assembly: when the door is closed, the elastic support assembly's stroke is fully compressed, providing a greater thrust to counteract the gas spring's resistance, resulting in less resistance when opening the door. Furthermore, the combination of the gas spring and elastic support assembly enables a slight self-locking function when the door is closed. When opening the door, the elastic support assembly assists in opening before the gas spring provides upward thrust; after the door is fully open, the gas spring provides thrust, at which point the elastic support assembly's stroke reaches its maximum and the thrust is minimum. This is to ensure the gas spring can support the door and prevent it from falling down, and to ensure that the elastic support assembly does not provide additional resistance when closing the door (the spring used in the elastic support assembly is a molded spring, whose thrust changes with the stroke, while the gas spring's thrust remains almost constant).

Detailed Implementation

[0018] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0019] like Figures 1 to 3 As shown, this embodiment provides an upward-opening door structure, including: a bracket 10 and an upward-opening door 20; both sides of the upward-opening door 20 are rotatably engaged with the bracket 10 through rotating shafts 30, and the rotating shafts 30 are respectively connected to the bracket 10 through support components 40;

[0020] The support assembly 40 includes a connecting rod 41, a gas spring 42, and an elastic support assembly 43; one end of the connecting rod 41 is fixedly connected to the rotating shaft 30, the other end of the connecting rod 41 is rotatably connected to one end of the gas spring 42, the other end of the gas spring 42 is rotatably connected to the bracket 10, one end of the elastic support assembly 43 is rotatably connected to the middle of the connecting rod 41, and the other end of the elastic support assembly 43 is rotatably connected to the bracket 10.

[0021] In this embodiment, the elastic support assembly 43 includes a sleeve 431, a slide rod 432, and a spring 433. One end of the slide rod 432 slides into the sleeve 431, and the other end of the slide rod 432 is rotatably connected to the middle of the connecting rod 41. The end of the sleeve 431 away from the slide rod 432 is rotatably connected to the bracket 10. A first limiting member 434 is provided on the outer side of the slide rod 432, and a second limiting member 435 is provided on the outer side of the sleeve 431. The spring 433 is sleeved on the outer side of the sleeve 431, and both ends of the spring 433 are connected to the first limiting member 434 and the second limiting member 435, respectively.

[0022] This upward-opening door structure achieves opening and closing through a combination of a gas spring 42 and an elastic support assembly 43. When the door is closed, the travel of the elastic support assembly 43 is fully compressed, providing a greater thrust to counteract the resistance of the gas spring 42, resulting in less resistance when opening the door. Furthermore, the combination of the gas spring 42 and the elastic support assembly 43 enables a slight self-locking function when the door is closed. When the door is fully open, the gas spring 42 provides the thrust, at which point the travel of the elastic support assembly 43 reaches its maximum, and the thrust is at its minimum. This is to ensure that the gas spring 42 can support the door and prevent it from falling down, and that the elastic support assembly 43 does not provide additional resistance when closing the door (the spring 433 used in the elastic support assembly 43 is a mold spring, whose thrust changes with the travel, while the thrust of the gas spring 42 remains almost constant).

[0023] In this embodiment, the second limiting member 435 is threadedly connected to the side wall of the sleeve 431, and is used to adjust the distance between the second limiting member 435 and the first limiting member 434. The first limiting member 434 is located on the side of the slide rod 432 away from the sleeve 431; the sleeve 431 is rotatably connected to the first fixed seat 50, which is mounted on the bracket 10; the end of the gas spring 42 away from the connecting rod 41 is rotatably connected to the second fixed seat 51, which is mounted on the bracket 10. The rotating shaft 30 is rotatably engaged with the third fixed seat 52, which is mounted on the bracket 10.

[0024] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
