Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, specifically to a flat-pressure hinge mechanism. This locking system can be applied to objects with high sealing requirements, such as energy storage containers. Background Technology

[0002] As a key infrastructure in the new energy field, the sealing and reliability of the door system of energy storage containers directly affect the safe operation of the internal electrical equipment. Currently, common energy storage container door systems on the market have the following technical defects—the hinge structure leads to uneven stress on the sealing strip.

[0003] Specifically, traditional hinges use a rotating mechanism around a pivot point to close, which prevents the sealing strip between the door panel and the frame from being pressed vertically together, and may even cause it to be damaged due to tilted force. This structure results in uncontrollable compression of the sealing strip, and after long-term use, the sealing strip at the hinge is prone to failure due to uneven stress, affecting the overall sealing effect of the container.

[0004] In summary, there is an urgent need for an energy storage container door system that can achieve uniform sealing force to solve the problems of sealing failure and insufficient structural durability in existing technologies. Utility Model Content

[0005] The purpose of this invention is to provide a flat-pressure hinge mechanism.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A flat-pressure hinge mechanism is installed between the door panel and the door frame to be locked, and at least one set is provided, each set including two brackets and two connecting rods;

[0008] One of the two brackets is fixed to the door panel, and the other is fixed to the door frame;

[0009] The two connecting rods are hinged at the middle, so that the two connecting rods form an X-shaped adjustment frame with an adjustable rotation angle;

[0010] The X-shaped adjustment frame is connected between the two supports, and when the door is open, the two supports are indirectly connected through the X-shaped adjustment frame and maintain a distance.

[0011] In a further technical solution, the first bracket of the two brackets is fixed to the inner side of the door panel, and the second bracket is fixed to the door frame and is arranged correspondingly to the first bracket.

[0012] In a further technical solution, one end of the first connecting rod is hinged to one end of the first bracket, and the other end is slidably connected to the second bracket along the length direction of the second bracket; one end of the second connecting rod is hinged to one end of the second bracket, and the other end is slidably connected to the first bracket along the length direction of the first bracket.

[0013] In a further technical solution, the first bracket has a first elongated hole along its length, and the other end of the second connecting rod is slidably connected to the first elongated hole; the second bracket has a second elongated hole along its length, and the other end of the first connecting rod is slidably connected to the second elongated hole.

[0014] In a further technical solution, both brackets are right-angle profiles with a horizontal surface and a vertical surface. The horizontal surface has the first elongated hole or the second elongated hole, and the vertical surface serves as the fixing surface to the door panel or the door frame.

[0015] In a further technical solution, the length of the second connecting rod is less than that of the first connecting rod, and a limiting groove is formed at the other end of the first connecting rod corresponding to the second connecting rod;

[0016] When the door is closed, the other end of the second connecting rod is located in the limiting groove.

[0022] The working principle and advantages of this utility model are as follows:

[0023] This invention provides an innovative flat-pressure angle-limiting hinge. Through a unique X-shaped adjustment frame design, it achieves a "first translate, then close" closing action, effectively solving the tilting or damage problems caused by traditional hinges when pressing the sealing strip. The design uses two hinged connecting rods forming an X-shaped structure with an adjustable rotation angle. When switching from the open to the closed state, the X-shaped adjustment frame maintains the initial distance between the door panel and the hinge point of the door frame, ensuring that the sealing strip is not prematurely compressed. During the closing process, the translational movement is completed first, followed by the final closure, allowing the pressure to be slowly and evenly released onto the sealing strips on all sides of the door frame, avoiding the concentrated pressure on the sealing strip in the initial closing stage of traditional hinges. This innovative hinge structure not only protects the sealing strip from damage caused by tilting forces but also significantly extends the service life of the sealing strip at the hinge point, thereby ensuring the overall sealing performance of the energy storage container door system under long-term operation and solving the sealing failure problem caused by traditional hinge designs.

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0039] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0040] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0041] See appendix Figure 1 As shown, the flat-pressure hinge mechanism of this embodiment is connected between the door panel 1 and the door frame 2 to be locked.

[0042] like Figures 2-13 As shown, the flat-pressure hinge mechanism has at least one set, and each set includes two brackets 21 and two connecting rods 22.

[0043] One of the two brackets 21 is fixed to the door panel 1, and the other is fixed to the door frame 2.

[0044] The two connecting rods 22 are hinged at the middle, so that the two connecting rods 22 form an X-shaped adjustment frame with an adjustable rotation angle.

[0045] The X-shaped adjustment frame is connected between the two supports 21, and in the open state, the two supports 21 are indirectly connected through the X-shaped adjustment frame and maintain a distance.

[0046] In this embodiment, the first bracket 21a of the two brackets 21 is fixed to the inner side of the door panel 1, and the second bracket 21b is fixed to the door frame 2 and is arranged corresponding to the first bracket 21a.

[0047] In this configuration, one end of the first connecting rod 22a is hinged to one end of the first bracket 21a, and the other end is slidably connected to the second bracket 21b along the length direction of the second bracket 21b; one end of the second connecting rod 22b is hinged to one end of the second bracket 21b, and the other end is slidably connected to the first bracket 21a along the length direction of the first bracket 21a.

[0048] Preferably, the first bracket 21a has a first elongated hole 211a along its length, and the other end of the second connecting rod 22b is slidably connected to the first elongated hole 211a; the second bracket 21b has a second elongated hole 211b along its length, and the other end of the first connecting rod 22a is slidably connected to the second elongated hole 211b.

[0049] Preferably, both brackets 21 are right-angle profiles with a horizontal surface 212 and a vertical surface 213. The horizontal surface 212 is provided with the first elongated hole 211a or the second elongated hole 211b, and the vertical surface 213 serves as the fixing surface to the door panel 1 or the door frame 2.

[0050] Preferably, the length of the second connecting rod 22b is less than that of the first connecting rod 22a, and the first connecting rod 22a has a limiting groove 25 at the other end of the second connecting rod 22b corresponding to the door; in the closed state, the other end of the second connecting rod 22b is located in the limiting groove 25.

[0051] The flat-pressure hinge mechanism of this utility model adopts a structural design of two connecting rods 22 hinged together to form an X-shaped adjustment frame. The two ends of the two connecting rods 22 respectively form a sliding and hinged engagement relationship with the two supports 21. When the system switches from the open state to the closed state, the X-shaped adjustment frame first maintains the initial distance between the two supports 21, so that the hinge point between the door panel 1 and the door frame 2 maintains an appropriate distance; then, through the rotation angle adjustment function of the X-shaped adjustment frame, the door panel 1 is driven to smoothly approach the door frame 2 to complete the closing action, realizing the closing process of "first moving, then closing".

[0052] In the initial stage of closing, the X-shaped adjusting bracket maintains the initial distance between the door panel 1 and the door frame 2, preventing the sealing strip 3 from being compressed prematurely. In the later stage of closing, the precise guidance of the adjusting bracket ensures that the door panel 1 smoothly presses against the door frame 2. This staged closing method ensures that the sealing strip 3 at the connection between the door panel 1 and the door frame 2 is evenly stressed, avoiding the tilting or concentrated pressure caused by traditional hinges. This effectively protects the sealing strip 3 and ensures that the system can maintain the required high sealing performance during long-term operation.

[0053] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
