Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a guide structure for preventing door deflection and a disinfection cabinet using the same. Background Technology

[0002] In daily life and industrial production, various types of equipment with door structures are widely used, such as common cabinets and boxes. The smoothness and stability of the opening and closing of these doors are crucial during use. However, many door structures currently suffer from door misalignment during actual use.

[0003] Taking disinfection cabinets as an example, with the improvement of people's quality of life and health awareness, disinfection cabinets have become an indispensable appliance in family kitchens and catering establishments. Modern disinfection cabinets are often designed to be large in size to meet the storage needs of more tableware. When the user closes the cabinet door, due to the large door size, uneven weight distribution, and wear and tear on hinges and other connecting parts after prolonged use, the door is prone to shifting left and right during the closing process. This shift not only prevents the door from closing properly, affecting the sealing performance of the disinfection cabinet and thus reducing the disinfection effect, but also causes friction and collision between the door and the door frame, accelerating damage to the door and frame and shortening the lifespan of the equipment.

[0004] Furthermore, door misalignment is also a prominent issue in some large industrial enclosures. Due to their large size and weight, the doors of large enclosures are more difficult to control during opening and closing. Once misalignment occurs, it may affect the normal working environment inside the equipment and even pose a safety hazard.

[0005] Therefore, it is necessary to propose an improved technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0007] A guide structure for preventing door deflection includes a door frame and a door body rotatably connected to the door frame. The door body is provided with guide protrusions arranged along the rotation path of the door body. During the rotation and closing of the door body, the guide protrusions abut against the side of the door frame to guide the rotation of the door body and prevent the door body from deflecting in the left and right directions.

[0008] As a further embodiment of this utility model: the guide protrusion is elongated;

[0009] Extending along the side edge of the door;

[0010] Or it can extend along the side and top edge of the door.

[0011] As a further embodiment of this utility model: the convex surface of the guide protrusion faces the door frame.

[0012] As a further embodiment of this utility model: the guide protrusion and the door body are integrally formed.

[0013] As a further embodiment of this utility model: the guide protrusion is composed of a top horizontal section, a first vertical side section, and a second vertical side section;

[0014] The top horizontal section is located at the top edge of the door and guides the top position when the door rotates;

[0015] The first vertical side section extends vertically along one edge of the door body, and the second vertical side section extends vertically along the other edge of the door body, respectively guiding and constraining the two sides of the door body.

[0016] As a further embodiment of this utility model: the top horizontal segment, the first vertical side segment, and the second vertical side segment transition smoothly into each other;

[0017] The first vertical side section extends upward from one edge of the door to the top and connects with the top horizontal section. The top horizontal section extends along the top edge of the door and then smoothly connects with the second vertical side section from the top. The second vertical side section extends downward along the other edge of the door.

[0018] As a further embodiment of this utility model: both the first vertical side section and the second vertical side section have a gradient shape. When extending from the top of the door to the side, the outline gradually narrows from wide to narrow and the thickness gradually thins from thick to thin, with a smooth and continuous curve transition to form a gradient shape.

[0019] This utility model also proposes a disinfection cabinet that applies the aforementioned door offset prevention guide structure, including a cabinet body and a cabinet door rotatably connected to the cabinet body, the cabinet door having the door body structure, and the cabinet body having the door frame structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1) The guide structure for preventing door offset and the disinfection cabinet using this structure, through the innovative design and reasonable arrangement of the guide protrusions, effectively solve the existing door offset problem, which has significant practicality and innovation, and can bring a better user experience and performance improvement to various equipment with door structures and related application scenarios.

[0022] 2) The guide protrusion consists of a top horizontal section, a first vertical side section, and a second vertical side section. The three sections are connected to each other to form a coherent and smooth overall structure. This structure does not add complex components or make too many structural modifications to the door surface. It does not damage the integrity of the door surface and achieves the guiding function through a simple form. During the rotation of the door, this coherent structure can smoothly transmit the guiding force and avoid stress concentration caused by structural abrupt changes.

[0023] 3) When the disinfection cabinet is in the open position, the guide protrusion on the door can also serve as a flow channel. Due to its smooth surface and specific slope, the condensate generated inside the cabinet will flow orderly to the bottom edge of the door along the flow path formed by the top horizontal section, the first vertical side section and the second vertical side section of the guide protrusion. This prevents the condensate from dripping randomly into other places inside the cabinet or directly onto the ground, keeping the inside and surrounding environment of the disinfection cabinet clean and dry, and reducing the risk of component corrosion caused by water accumulation.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-2 In this embodiment of the utility model, a guide structure for preventing door deflection is mainly composed of a door frame 1 and a door body 2 rotatably connected to the door frame 1. Its core innovation lies in the provision of guide protrusions 3 arranged along the rotation path of the door body 2 on the door body 2.

[0033] During the rotation and closing of the door 2, the guide protrusion 3 will abut against the side of the door frame 1. When the door 2 starts to rotate and gradually approaches the closed position, that is, when the door 2 rotates from the open state to the closed state to a certain angle, the guide protrusion 3 begins to play its role, contacting the side of the door frame 1 and providing guiding force. This guiding force can correct any deviations that may occur in the left and right directions of the door 2 in real time, so that the door 2 can close accurately along the predetermined rotation path. This design fundamentally solves the existing door 2 offset problem and greatly improves the accuracy and stability of the door 2 closing.

[0034] Guide protrusion 3 has the following optimized design features:

[0035] Shape and Extension Method: The guide protrusion 3 is elongated. Depending on the actual application requirements, there are two possible arrangements. One is to extend along the side edge of the door body 2. This arrangement only extends along the side edge of the door body 2 and directly acts on the side of the door body 2. When the door body 2 rotates, it directly corrects the left and right offset of the door body 2 by abutting against the side of the door frame 1. The other is to extend along the side and top edges of the door body 2. In this method, the side extension still undertakes the main function of correcting the left and right offset, while the top extension does not directly correct the left and right offset. However, by cooperating with the top of the door frame 1, it restricts the vertical movement of the door body 2, ensuring that the top of the door body 2 is precisely aligned with the top of the door frame 1 and maintaining the overall sealing. At the same time, the top extension and the side extension work together to maintain the posture of the door body 2 when the door body 2 is twisted or shaken by external forces, indirectly assisting in correcting the left and right offset and simultaneously enhancing the overall guiding stability.

[0036] Integrated Molding and Orientation: The guide protrusion 3 and the door body 2 are integrally molded. During the manufacturing process, the guide protrusion 3 and the door body 2 are manufactured as a whole, ensuring the connection strength and stability between the two. Compared with the structure of installing the guide protrusion 3 on the door body 2 through subsequent assembly or connection, the integrated molding structure avoids the guiding error caused by loosening or deformation of the connection parts, so that the guide protrusion 3 can more accurately follow the rotation of the door body 2 and play its role. At the same time, the convex surface of the guide protrusion 3 faces the door frame 1. This design makes the contact between the guide protrusion 3 and the side of the door frame 1 more reasonable. The shape of the convex surface can disperse the contact pressure when it abuts against the side of the door frame 1, reduce wear, and make the guiding process smoother, reducing the resistance when the door body 2 rotates.

[0037] Segmented Structure and Transition: The guide protrusion 3 consists of a top horizontal segment 4, a first vertical side segment 5, and a second vertical side segment 6. The top horizontal segment 4 is located at the top edge of the door body 2. When the door body 2 rotates, the top horizontal segment 4 can guide and constrain the top position of the door body 2. Since the top position of the door body 2 is prone to left and right displacement during rotation, the top horizontal segment 4 can effectively constrain the movement of the top of the door body 2, ensuring accurate alignment between the top of the door body 2 and the top of the door frame 1. The first vertical side segment 5 extends vertically along one edge of the door body 2, and the second vertical side segment 6 extends vertically along the other edge of the door body 2. They guide and constrain the two sides of the door body 2 respectively. The first vertical side segment 5 and the second vertical side segment 6 on both sides can prevent the door body 2 from swinging in the left and right directions, ensuring that the two sides of the door body 2 remain parallel to the sides of the door frame 1 during rotation.

[0038] The top horizontal section 4, the first vertical side section 5, and the second vertical side section 6 are smoothly transitioned to each other. The first vertical side section 5 extends upward from one edge of the door body 2 to the top and connects with the top horizontal section 4. The top horizontal section 4 extends along the top edge of the door body 2 and then smoothly connects with the second vertical side section 6 from the top. The second vertical side section 6 extends downward along the other edge of the door body 2. This continuous and smooth transition design allows the guide protrusion 3 to provide stable and consistent guiding force at various key parts of the door body 2. For example, during the rotation of the door body 2, the movement trajectory of the door body 2 is continuous. The smoothly transitioned guide protrusion 3 can better adapt to the movement of the door body 2 and avoid sudden changes in guiding force due to discontinuity of the guide protrusion 3, thereby enhancing the overall guiding performance.

[0039] Gradual Shape: Both the first vertical side section 5 and the second vertical side section 6 have a gradual shape. As they extend from the top of the door body 2 to the side, their outline gradually narrows and their thickness gradually decreases, transitioning smoothly and continuously with a curve to form a gradual shape. This gradual design is an optimization based on the force and motion characteristics of the door body 2 at different positions during rotation. At the top of the door body 2, due to the greater inertia and force during rotation, the wider and thicker guide protrusion 3 can provide greater guiding and supporting force. As it extends to the side, the force on the door body 2 gradually decreases, and the narrower and thinner guide protrusion 3 can reduce the obstruction to the movement of the door body 2 while ensuring the guiding function. This gradual shape can better adapt to the relative movement between the door body 2 and the door frame 1, allowing the guide protrusion 3 to play the best guiding role at different positions, while also reducing the resistance that may be generated during the guiding process and improving the smoothness of the rotation of the door body 2.

[0040] Please see Figure 3 Disinfection cabinets using this guide structure

[0041] This utility model also provides a disinfection cabinet that applies the above-mentioned anti-door offset guiding structure. The disinfection cabinet includes a cabinet body 7 and a cabinet door 8 that is rotatably connected to the cabinet body 7. The cabinet door 8 has a door body 2 structure (which can be regarded as the inner door body of the cabinet door), and the cabinet body 7 has a door frame 1 structure.

[0042] To meet the storage needs of more tableware, modern disinfection cabinets are often designed to be large in size. When the user closes the cabinet door 8, due to the large size of the cabinet door 8, uneven weight distribution, and wear and tear on hinges and other connecting parts after long-term use, the cabinet door 8 is prone to shifting in the left and right directions during the rotation and closing process. By applying a guide structure to prevent door shifting to the disinfection cabinet, these problems can be effectively solved.

[0043] During the rotation and closing of the cabinet door 8, the guide protrusion 3 abuts against the side of the cabinet body 7 (door frame 1). Various parts of the guide protrusion 3, such as the top horizontal section 4, the first vertical side section 5, and the second vertical side section 6, guide the top and both sides of the cabinet door 8 respectively. The top horizontal section 4 ensures that the top of the cabinet door 8 accurately aligns with the top of the cabinet body 7, ensuring the sealing performance of the top of the disinfection cabinet. The vertical side sections on both sides prevent the cabinet door 8 from swinging in the left and right directions, allowing the cabinet door 8 to close smoothly. This guiding action ensures that the cabinet door 8 can close accurately and smoothly, improving the sealing performance of the disinfection cabinet. Good sealing performance is crucial for the disinfection cabinet, as it ensures the stability of internal conditions such as temperature, humidity, and disinfection gas concentration during the disinfection process, thereby guaranteeing the disinfection effect. At the same time, because the door body 2 can close accurately, it reduces friction and collision between the cabinet door 8 and the cabinet body 7, reduces the wear rate of components, and extends the service life of the disinfection cabinet.

[0044] Furthermore, the guide protrusion 3 is composed of a top horizontal section 4, a first vertical side section 5, and a second vertical side section 6. The three are connected to each other to form a coherent and smooth overall structure. This structure does not add any complex components or make too many structural modifications to the surface of the door body 2. It does not damage the integrity of the surface of the door body 2, and achieves the guiding function through a simple shape. During the rotation of the door body 2, this coherent structure can ensure that the guiding force is transmitted smoothly and avoid stress concentration caused by structural abrupt changes.

[0045] In addition, when the disinfection cabinet is in the open position, the guide protrusion 3 on the door 2 can also serve as a flow channel. Due to its smooth surface and specific slope, the condensate generated inside the cabinet will flow orderly to the bottom edge of the door 2 along the flow path formed by the top horizontal section 4, the first vertical side section 5, and the second vertical side section 6 of the guide protrusion 3. This prevents the condensate from dripping randomly into other places inside the cabinet or directly onto the ground, keeping the inside and surrounding environment of the disinfection cabinet clean and dry, and reducing the risk of component corrosion caused by water accumulation.

[0046] In summary, the guide structure for preventing door offset and the disinfection cabinet using this structure, through the innovative design and reasonable arrangement of the guide protrusions 3, effectively solve the existing door offset problem, demonstrating significant practicality and innovation. It can bring a better user experience and performance improvement to various devices with door structures 2 and related application scenarios.
